ACTION: Final rule. AGENCY: The Environmental Protection Agency (EPA or the Agency) is making certain revisions to the 1988 underground storage tank (UST) regulation and to the 1988 state program approval (SPA) regulation. These changes establish Federal requirements that are similar to key portions of the Energy Policy Act of 2005 (EPAct); they also update the 1988 UST and SPA regulations. Changes to the regulations include: Adding secondary containment requirements for new and replaced tanks and piping; adding operator training requirements; adding periodic operation and maintenance requirements for UST systems; addressing UST systems deferred in the 1988 UST regulation; adding new release prevention and detection technologies; updating codes of practice; making editorial corrections and technical amendments; and updating state program approval requirements to incorporate these new changes. EPA thinks these changes will protect human health and the environment by reducing the number of releases to the environment and quickly detecting releases, if they occur.

III. Background tkelley on DSK3SPTVN1PROD with RULES2 A. Changes to the UST Regulations After reviewing and incorporating comments received during the five month public comment period, EPA is finalizing certain changes to the 1988 UST regulation in 40 CFR part 280. EPA is also revising its SPA regulation in 40 CFR part 281 to incorporate the changes in 40 CFR part 280. These revisions strengthen the 1988 UST regulation by increasing the emphasis on properly operating and maintaining equipment. The 1988 UST regulation required owners and operators to have spill, overfill, and release detection equipment in place for their UST systems, but did not require proper operation and maintenance for some of that equipment. For example, EPA required spill prevention equipment to capture drips and spills when the delivery hose is disconnected from the fill pipe, but did not require periodic testing of that equipment. These revisions require that UST equipment is operated and maintained properly, which will improve environmental protection. These revisions also acknowledge improvements in technology over the last 26 years, including the ability to detect releases from UST systems deferred in the 1988 UST regulation. EPA is revising the 1988 UST regulation to: • Establish federal requirements that are similar to certain key provisions of the Energy Policy Act of 2005; • Ensure owners and operators properly operate and maintain their UST systems; VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 • Address UST systems deferred in the 1988 UST regulation; • Include updates to current technology and codes of practices; • Make technical and editorial corrections; and • Update the SPA regulation to address the changes listed above. In 1988, EPA first promulgated the UST regulation (40 CFR part 280) to prevent, detect, and clean up petroleum releases into the environment. The 1988 UST regulation required new UST systems to be designed, constructed, and installed to prevent releases; existing UST systems had to be upgraded to prevent releases. In addition, owners and operators were required to perform release detection, demonstrate financial responsibility, and clean up releases. The Energy Policy Act of 2005 amended Subtitle I of SWDA, the statute that authorized the UST program. Key Energy Policy Act provisions (such as secondary containment and operator training) apply to all states and United States’ territories, hereafter referred to as states, receiving federal Subtitle I money under SWDA, regardless of their state program approval status, but do not apply in Indian country. The United States has a unique legal relationship with federally recognized Indian tribes. This government to government relationship includes recognizing the rights of tribes as sovereign governments with the right to self-determination and acknowledging the federal government’s trust responsibility to tribes. As a result, EPA directly implements the UST program in Indian country. In order to establish federal UST requirements that are similar to the UST secondary containment and operator training requirements of the Energy Policy Act, EPA decided to revise the 1988 UST regulation. These revisions also fulfill objectives in EPA’s August 2006 UST Tribal Strategy,1 where both EPA and tribes recognized the importance of requirements that ensure parity in program implementation Tribal Strategy, https://epa.gov/oust/ fedlaws/tribalst.htm. PO 00000 1 2006 Frm 00003 Fmt 4701 Sfmt 4700 111, 112. among states and in Indian country. Secondary containment will reduce releases to the environment by containing them within a secondary area and detecting them before they reach the environment. Operator training will educate UST system operators and help them prevent releases by complying with the regulation and performing better operation and maintenance of their UST systems. Since the beginning of the UST program, preventing petroleum and hazardous substance releases from UST systems into the environment has been one of the primary goals of the program. Although EPA and our partners have made significant progress in reducing the number of new releases, approximately 6,000 releases are discovered each year as of FY 2013.2 Lack of proper operation and maintenance of UST systems is the main cause of new releases. Information on sources and causes of releases shows that releases from tanks are less common than they once were. However, releases from piping and spills and overfills associated with deliveries have emerged as more common problems. In addition, releases at the dispenser are one of the leading sources of releases. Finally, data show that release detection equipment is only detecting approximately 50 percent of releases it is designed to detect. These problems are partly due to improper operation and maintenance. See section IV.B, Additional Requirements for Operation and Maintenance for a more detailed discussion of problems. EPA relied on two draft causes of releases studies to help support this final UST regulation. Petroleum Releases at Underground Storage Tank Facilities in Florida contains release data on 512 releases from new and 2 Semi-Annual Report Of UST Performance Measures, End Of Fiscal Year 2013, https://epa.gov/ oust/cat/camarchv.htm. E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 41568 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations upgraded tanks in Florida.3 The second draft study, Evaluation of Releases from New and Upgraded Underground Storage Tank Systems, contains release data on 580 releases from new and upgraded tanks in 23 states across the Northeast, South, and Central parts of the United States.4 Taken together, these draft studies provide information on 1,092 releases in 24 of 50 states. The data in the two studies generally provide a representative sampling of releases across the United States, because nearly half of the states contributed to the studies. Both drafts were peer reviewed but never finalized because passage of the Energy Policy Act of 2005 required a reallocation of personnel and resources. Even though these studies were never finalized, the underlying data and calculations can be used to support this final UST regulation because that information did not change as a result of the peer review process. These studies are available in the docket for this final action. Many USTs currently in the ground were upgraded to meet the spill, overfill, corrosion protection, and release detection requirements in the 1988 UST regulation. As these USTs continue to age, it is vital that we ensure they are still working as intended. These revisions to the 1988 UST regulation focus on ensuring equipment is working, rather than requiring UST owners and operators to replace or upgrade equipment already in place. The 1988 UST regulation requires owners and operators to use equipment that could help prevent releases. These revisions highlight the importance of operating and maintaining UST equipment so releases to the environment are prevented or quickly detected. This final UST regulation addresses UST systems deferred in the 1988 UST regulation by removing the deferral and regulating UST systems with fieldconstructed tanks, airport hydrant fuel distribution systems that meet the UST definition, and UST systems storing fuel solely for use by emergency power generators. Note that aboveground storage tanks associated with UST systems with field-constructed tanks and airport hydrant fuel distribution systems that meet the UST definition are partially excluded in this final UST regulation. EPA is partially excluding wastewater treatment tank systems that are not part of a wastewater treatment 3 Petroleum Releases At Underground Storage Tank Facilities In Florida, Peer Review Draft, US EPA/OUST, March 2005. 4 Evaluation Of Releases From New And Upgraded Underground Storage Tanks, Peer Review Draft, US EPA/OUST, August 2004.

See section IV.C, Addressing Deferrals, for more information. EPA is revising the 1988 SPA regulation (40 CFR part 281) to address the changes to 40 CFR part 280. By doing so, states will generally need to adopt the 40 CFR part 280 changes finalized today in order to obtain or retain SPA. Please note that, although not a part of this final UST regulation, owners and operators may also be subject to other requirements related to underground storage tank systems. For example, EPA’s Office of Air and Radiation has national emission standards for hazardous air pollutants for various source categories, including gasoline dispensing facilities (see 40 CFR part 63). These standards include some testing for UST systems, depending on the monthly throughput of the facility. Finally, EPA allows owners and operators the flexibility to maintain either paper or electronic records to demonstrate compliance with this final UST regulation. EPA encourages owners and operators to maintain records electronically, which promotes innovation 5 and simplifies compliance by using 21st century technology tools.6 B. History of the UST Laws and Regulations In 1984, Congress responded to the increasing threat to groundwater posed from leaking USTs by adding Subtitle I to SWDA, commonly referred to as RCRA. Subtitle I of SWDA required EPA to develop a comprehensive regulatory program for USTs storing petroleum or certain hazardous substances, ensuring that the environment and human health are protected from UST releases. In 1986, Congress amended Subtitle I of SWDA and created the Leaking Underground Storage Tank Trust Fund to implement a cleanup program and pay for cleanups at sites where the owner or operator is unknown, unwilling, or unable to respond, or which require emergency action. In 1988, EPA promulgated the UST regulation (40 CFR part 280), which set 5 Executive Order 13563, ‘‘Improving Regulation And Regulatory Review,’’ Section 3, see https:// www.gpo.gov/fdsys/pkg/FR-2011-01-21/pdf/20111385.pdf. 6 EPA Budget in Brief, February 2012, p. 4, see https://yosemite.epa.gov/sab/sabproduct.nsf/ 2B686066C751F34A852579A4007023C2/$File/ FY2013_BIB.pdf. PO 00000 Frm 00004 Fmt 4701 Sfmt 4700 minimum standards for new UST systems and required owners and operators of existing UST systems to upgrade, replace, or close them. In addition, after 1988 owners and operators were required to report and clean up releases from their USTs. The 1988 UST regulation set deadlines for owners and operators to meet those requirements by December 22, 1998. Owners and operators who chose to upgrade or replace had to ensure their UST systems included spill and overfill prevention equipment and were protected from corrosion. In addition, owners and operators were required to monitor their UST systems for releases using release detection (phased in through 1993, depending on when their UST systems were installed). Finally, owners and operators were required to demonstrate financial responsibility (phased in through 1998), which ensured they have financial resources to pay for cleaning up releases. EPA has not significantly changed the UST regulation since 1988. In 1988, EPA also promulgated a regulation for state program approval (40 CFR part 281). Since states are the primary implementers of the UST program, EPA established a process where state programs could operate in lieu of the federal program, if states met certain requirements and obtained state program approval from EPA. The state program approval regulation describes minimum requirements states must meet so their programs can be approved and operate in lieu of the federal program. In 2005, the Energy Policy Act further amended Subtitle I of SWDA. The Energy Policy Act required states receiving Subtitle I money from EPA to meet certain requirements. EPA developed grant guidelines for states regarding: Operator training; inspections; delivery prohibition; secondary containment; financial responsibility for manufacturers and installers; public record; and state compliance reports on government USTs.7 The operator training and secondary containment requirements are two major pieces of the Energy Policy Act that did not apply in Indian country, but will now apply with publication of this final UST regulation. C. Potential Impact of This Regulation This final UST regulation will improve parity in program implementation among states and in Indian country. This regulation is adding to the federal UST regulation 7 EPA guidelines for the Energy Policy Act can be found at: https://epa.gov/oust/fedlaws/epact_05.htm. E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations certain requirements, which will apply in Indian country. These requirements are similar to the Energy Policy Act’s operator training and secondary containment requirements, which apply in states receiving federal Subtitle I money from EPA. This action will also further strengthen protection of human health and the environment from UST releases by increasing the emphasis on proper operation and maintenance of release prevention and release detection equipment. These revisions also reflect improvements in technology that allow for the ability to prevent and quickly detect releases for many tank systems currently deferred from regulation under Subtitle I. The regulatory changes finalized today impose costs to owners and operators of existing regulated UST systems and owners and operators of USTs deferred in the 1988 UST regulation, as well as costs associated with state review of the changes. EPA prepared an analysis of the potential incremental costs and benefits associated with this action. This analysis is contained in the regulatory impact analysis (RIA) titled Assessment of The Potential Costs, Benefits, and Other Impacts of the Final Revisions to EPA’s Underground Storage Tank Regulations, which is available in the docket for this action. Numerous commenters submitted input relaying their concerns about the costs and feasibility of specific requirements in the 2011 proposed UST regulation. EPA considered these comments and adjusted this final UST regulation to alleviate some of the burden on owners and operators. For example, EPA is requiring testing of spill prevention equipment every three years instead of annually. EPA also adjusted some of the assumptions underlying the RIA to reflect information received from 41569 commenters. For example, several commenters provided water disposal costs associated with spill bucket testing. While the RIA for the 2011 proposed UST regulation assumed these costs were part of the spill prevention testing cost, EPA adjusted this assumption to reflect that, in some cases, owners and operators will incur additional costs to dispose of the water. A summary of these impacts is provided in section VI, Overview of Estimated Costs and Benefits, and in the table below. Note that due to data and resource constraints, EPA was unable to quantify or monetize some of this final UST regulation’s benefits, including avoidance of human health risks, groundwater protection, ecological benefits, and mitigation of acute exposure events and large-scale releases (e.g., releases from airport hydrant distribution systems and UST systems with field-constructed tanks).

The risk assessment examined potential impacts to groundwater and subsequent chemical transport, exposure, and risk. EPA decided not to spend resources to finalize the risk assessment through a formal peer review process, because the results from the risk assessment did not materially impact the RIA. Changes brought about by this final UST regulation are not expected to significantly alter these outcomes. The risk assessment developed for the 2011 proposed UST regulation is available for review in the docket. D. EPA’s Process in Deciding Which Changes To Incorporate in the Regulations After the Energy Policy Act became law, EPA recognized a need to revise the 1988 UST regulation. The Energy Policy Act required additional measures to protect groundwater (either with secondary containment or financial responsibility for manufacturers and installers) and operator training VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 requirements in states receiving federal Subtitle I money from EPA. However, no similar requirements would apply in Indian country until EPA promulgates a regulation. Both EPA and tribes are committed to ensuring program parity between states and in Indian country, and this final UST regulation achieves this parity. For the past 26 years, the 1988 UST regulation worked well to provide environmental protection. However, over two decades of experience implementing the UST program have shown there are a number of areas where EPA can improve the UST program and increase environmental protection. For example, updating the UST regulation to reflect current technologies and ensuring release prevention and release detection equipment are properly operated and maintained have surfaced as areas needing improvement and are included as part of this final UST regulation. Throughout the regulatory development process, EPA embraced an open, inclusive, and transparent process so all UST stakeholders had an opportunity to share their ideas and concerns. EPA recognizes concerns PO 00000 Frm 00005 Fmt 4701 Sfmt 4700 about costs to owners and operators and the importance of limiting requirements for retrofits. In developing this action, EPA reached out to stakeholders involved in all aspects of the tank program, provided multiple opportunities for sharing ideas, and kept stakeholders informed of progress. As a result of the information collected during our extensive outreach to stakeholders, EPA published proposed regulations in the November 2011 Federal Register.8 In order to ensure all stakeholders had an opportunity to comment, EPA provided a five month public comment period on the proposed UST and SPA regulations. A number of commenters provided general input on EPA’s 2011 proposal to update the UST and SPA regulations. Many commenters appreciated the extensive stakeholder outreach EPA conducted prior to drafting the proposed changes to the UST and SPA 8 Proposed Rule Revising the Underground Storage Tanks Regulation. Federal Register. November 18, 2011. https:// www.federalregister.gov/articles/2011/11/18/201129293/revising-underground-storage-tankregulations-revisions-to-existing-requirements-andnew. E:\FR\FM\15JYR2.SGM 15JYR2 41570 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations regulations. A few commenters believed EPA’s outreach was not adequate. EPA conducted extensive stakeholder outreach before publishing the proposal; we held more than 100 meetings with stakeholders during the two years prior to issuing the 2011 proposed UST and SPA regulations. To further understand comments and concerns, EPA continued to meet with all interested stakeholders during and after the five month public comment period. Most commenters expressed support for the general revisions to the 1988 UST and SPA regulations. They supported updating the regulations because technology has changed a great deal since the 1980s. Many commenters provided specific concerns on particular topics in the 2011 proposed UST and SPA regulations. We discuss these comments throughout the preamble for this action. Several commenters opposed the changes to the regulations due to concerns about potential costs on owners, especially small businesses. A few commenters requested EPA withdraw the entire proposal and conduct a small business advocacy review panel under the Regulatory Flexibility Act. EPA carefully considered the potential impacts of the proposal on small businesses and determined that a small business panel was not required. EPA also considered all of the comments submitted during the public comment period, including those concerns regarding the potential costs on small businesses, and worked to minimize those costs by making certain changes to the final regulations. EPA did not change this final UST and SPA regulations when comments were beyond the scope of the regulations or beyond EPA’s statutory authority. E. Implementation Timeframe This final UST regulation aligns the implementation time frames for the new operator training, operation and maintenance, and previously deferred UST system requirements. The table below provides the implementation time frames for each of the new requirements.

Walkthrough inspections. EPA proposed different implementation time frames for the various requirements, and for several requirements, a phased in approach based on tank age. Based on commenter input, EPA is not using the phased in approach and instead is requiring owners and operators to meet the requirements as described in the implementation table above. In addition, with one exception EPA is aligning implementation of the requirements in this final UST regulation to begin on the effective date of the UST regulation or three years after the effective date of the UST regulation. The requirements implemented on the effective date of the final UST regulation are those that either do not require significant VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 education and outreach or apply to new installations, repairs, or releases. EPA is allowing up to three years for owners and operators to implement the requirements that require significant outreach, equipment to be upgraded or installed (such as for previously deferred UST systems), or scheduling and testing. Three years allows ample time for implementing agencies to educate owners and operators about this new requirements and allows owners and operators to schedule testing. The exception to implementing the requirements immediately or in three years is that EPA is implementing the secondary containment requirement 180 days after the effective date of the UST regulation. The 180 day time frame allows flexibility for those owners and PO 00000 Frm 00006 Fmt 4701 Sfmt 4700 operators who have concrete plans but have not yet applied for or obtained approvals or permits for a new UST system installation. IV. Revisions to the Requirements for Owners and Operators of Underground Storage Tank Systems The following sections describe this final UST regulation, starting with establishing new requirements for operator training and secondary containment. The next four sections 9 Note that EPA is requiring owners and operators to also submit a one-time notification of existence for these UST systems within 3 years of the effective date of this final UST regulation. Owners and operators must demonstrate financial responsibility when they submit the one-time notification form E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations address changes to the 1988 UST regulation, organized by topic: Additional requirements for operation and maintenance; addressing UST systems deferred in the 1988 UST regulation; other changes to improve release prevention and release detection; and general updates to the 1988 UST regulation. Finally, there is a section describing alternative options considered. tkelley on DSK3SPTVN1PROD with RULES2 A. Establishing Federal Requirements for Operator Training and Secondary Containment 1. Operator Training This final UST regulation adds a new subpart J, which contains operator training requirements to ensure properly trained individuals operate all regulated UST systems. The operator training provision of the Energy Policy Act of 2005 requires implementing agencies, as a condition of receiving federal Subtitle I money, develop state-specific training requirements for three classes of UST system operators. EPA issued grant guidelines that provide minimum requirements state operator training programs must include in order for states to continue receiving federal Subtitle I money.10 All states are implementing or plan to implement operator training. The EPAct did not specifically require operator training in Indian country. To bring UST systems in Indian country to the same level of protection as UST systems in states, this final UST regulation implements operator training requirements. This final UST regulation closes the gap in coverage and ensures all operators designated as Class A, B, or C operators are trained according to their level of responsibility. Sufficiently training designated UST operators will increase compliance with regulatory requirements. In addition, operator training should decrease UST system releases by educating Class A, B, and C operators about their UST system requirements and result in greater protection of human health and the environment. The operator training requirements in this final UST regulation are consistent with the requirements in EPA’s operator training grant guidelines for states. In both, EPA establishes minimum operator training requirements, yet allows flexibility to tailor training programs for specific needs. This means that although there may be variations among operator training programs, all 10 Grant Guidelines To States For Implementing The Operator Training Provision Of The Energy Policy Act Of 2005: www.epa.gov/oust/fedlaws/ optraing.htm. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 Class A, B, and C operators will have a minimum level of knowledge about their UST system requirements. Definitions EPA is adding definitions for the three operator classes requiring training to distinguish them from the term operator originally defined in the 1988 UST regulation and maintained in this final UST regulation. Only if Class A, B, or C operators meet the definition of operator will they be subject to the same responsibilities and liabilities as an operator. EPA’s definitions of Class A, B, and C operators do not relieve UST system owners and operators from legal responsibility for complying with the UST regulation. EPA based the three operator class definitions on duties each typically perform at UST facilities. Commenters on the 2011 proposed UST regulation indicated this final UST regulation should further differentiate Class A, B, and C operators from EPA’s definition of operator. EPA agrees with commenters and is changing the title of § 280.241 to Designation of Class A, B, and C operators in the final UST regulation. This change correctly identifies the individuals who must be designated. With the exception of the definition for the Class C operator, the operator class definitions remain unchanged from the 2011 proposed UST regulation. Several commenters pointed out that UST system owners and operators were, at the time of the 2011 proposed UST regulation, using contractors to perform Class C operator functions. Some commenters believed EPA was restricting the use of a contractor as a Class C operator since the proposal required a Class C operator to be an employee. EPA agrees; we are removing the restriction. EPA does not intend for the operator training requirements to restrict UST system owners and operators who are using contractors to operate their UST systems. EPA added a definition for training program in the 2011 proposed UST regulation; we are modifying it in this final UST regulation. It is important that training programs for Class A, B, and C operators include both sharing information and evaluating knowledge. Several commenters requested clarification on how EPA expected knowledge to be verified. To address these requests, EPA changed the definition of training program by adding the phrase ‘‘through testing, practical demonstration, or another approach acceptable to the implementing agency.’’ This addition clarifies the definition and makes it consistent with PO 00000 Frm 00007 Fmt 4701 Sfmt 4700 41571 how the term is used in this final UST regulation. How Operators Are Designated This final UST regulation indicates how UST owners and operators are to designate the three operator classes for their facilities. UST owners and operators must designate at least one Class A and B operator at each facility. Class A and B operators may provide training to Class C operators, which should help UST owners and operators comply with this requirement. The UST owner and operator must ensure Class C operator training is documented. Because Class C operators’ duties typically require them to provide initial responses to emergencies, individuals who meet the Class C operator definition must be designated as such and trained in UST system emergency response—for example response to release detection alarms, spills, or releases. EPA received several comments on the 2011 proposed UST regulation requesting we require only one Class C operator be designated. The final UST regulation requires all individuals who meet the definition of Class C operator be trained. EPA maintains that the initial response to emergencies provided by this operator class is important to environmental protection. Requiring training for all individuals who meet the Class C operator definition will increase the likelihood UST system emergencies are quickly and appropriately addressed. This does not mean all workers need to be trained. For example, numerous workers at convenience stores do not control or monitor dispensing or sale of petroleum products, nor are they responsible for initial alarms. As a result, it is unnecessary to designate and train these individuals to meet Class C operator training requirements. In addition, EPA acknowledges some readers might misinterpret that control of the dispensing operation described in the definition of the Class C operator applies to anyone fueling a vehicle. The level of UST system control and responsibility of individuals who must be trained excludes customers who are pumping product into their vehicles. For example, police officers using an unmanned facility would not have to meet Class C operator training requirements unless they are responsible, as specifically tasked by UST system owners and operators, to respond to emergencies and alarms caused by spills or releases from the UST system. In the preamble to the 2011 proposed UST regulation, EPA acknowledged that many UST owners and operators might E:\FR\FM\15JYR2.SGM 15JYR2 41572 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations want to designate one person at an UST facility to fulfill more than one class of operator. This final UST regulation allows one person to serve in multiple operator classes; however, that person must be trained for each class designated. EPA is aware owners and operators rely on contractors to perform various UST system tasks, including those of Class A, B, and C operators. Because of the current use of contractors, EPA is allowing UST owners and operators to designate contractors as their Class A, B, and C operators, as long as they are trained in all areas for the class of operator designated. UST owners and operators must maintain documentation containing individual names (not just company names) of Class A, B, and C operators. This will allow implementing agencies to use individual names, rather than company names, when verifying training, retraining, and refresher training. tkelley on DSK3SPTVN1PROD with RULES2 Who Must Be Trained This final UST regulation requires training for designated Class A, B, and C operators at UST systems regulated under Subtitle I. This includes UST systems at attended and unattended facilities. An unattended UST facility means a Class A, B, or C operator might not be present when a facility is operating. Nonetheless, even for unattended UST facilities, owners and operators must designate and train Class A, B, and C operators. Requirements for Operator Training In the operator training grant guidelines for states, EPA based the three operator classes on duties each typically perform at UST facilities. Building on that, this final UST regulation requires each person designated in an operator class to participate in a specific training program or pass an examination comparable to the training program. • For Class A operators, the training program must teach and evaluate their knowledge to make informed decisions regarding compliance and determine whether appropriate people are performing the operation, maintenance, and recordkeeping requirements for UST systems. • For Class B operators, the training program must teach and evaluate their knowledge and skills to implement UST regulatory requirements on typical UST system components or site-specific equipment at UST facilities. • For Class C operators, the training program must teach and evaluate their knowledge to take appropriate action, including notifying appropriate VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 authorities, in response to emergencies or alarms caused by spills or releases from UST systems. • For all operator classes, the test is based on the training program and evaluates the minimum knowledge required for the operator class. EPA received several comments on the description of Class C operator training requirements. One commenter suggested EPA should clarify the scope of emergencies a Class C operator is trained on. This final UST regulation requires Class C operators receive training on emergencies or alarms caused by spills or releases from operating UST systems. EPA also agrees with the comment regarding Class C operator training avoiding triggering the Hazardous Waste Operations and Emergency Response (HAZWOPER) standard. HAZWOPER is the United States’ recognized standard of safety requirements employers and their subcontractors or public sector responders must meet in order to conduct cleanups or emergency response operations. The level of training in this standard is beyond that which EPA intends for Class C operators. This final UST regulation modifies the training requirements for Class C operators and clarifies that appropriate actions Class C operators can take include notifying appropriate authorities. For each class of operator, EPA considered developing specific training curricula prescribing length of training, topic areas, and trainer qualifications. Instead, this final UST regulation provides general criteria and requirements, because they provide flexibility while ensuring each class of operator is trained in a way that is comparable to EPA’s operator training grant guidelines for states. EPA also modified the lists of training requirements for Class A and B operators from those identified in the 2011 proposal. The modifications made it clearer that new operation and maintenance inspection and testing, and compatibility demonstration requirements must be covered by operator training programs and comparable examinations. EPA received several comments regarding restrictions on who may develop and administer the evaluation component of training, as well as restrictions on who may train Class A and B operators. This final UST regulation removes those restrictions because they could prohibit in-house and other potentially viable training. EPA supports a variety of operator training approaches. However, for retraining, EPA is revising language in PO 00000 Frm 00008 Fmt 4701 Sfmt 4700 § 280.244 to address conflicts of interest. This final UST regulation requires the training program or comparable examination to be developed or administered by an independent organization, the implementing agency, or a recognized authority. These retraining restrictions will help address any ineffective training approaches. This final UST regulation allows a variety of ways to train operators, including classroom, computer based, hands on, and any combination of these. In lieu of completing a training program, Class A, B, or C operators can pass a comparable examination—such as classroom, Internet, or computer based—that meets the requirements for operator training described in this final UST regulation. When Designated Operators Must Complete Operator Training This final UST regulation requires UST owners and operators ensure all Class A, B, and C operators successfully complete a training program or a comparable examination within three years of the effective date of this final UST regulation. EPA proposed a phased in approach over three years, based on UST installation dates because older USTs potentially pose a greater risk to the environment and Class A, B, and C operators of those systems should be trained first. EPA received comments strongly indicating EPA should not phase in the operator training requirements. EPA agrees with commenters that it is less confusing to establish a single compliance date for this requirement. EPA is aligning implementation of operator training with the three year inspection requirement, which will make it easier for UST system owners and operators to comply. Consistent with EPA’s operator training grant guidelines, new operators designated after the three year implementation period must be trained as follows: • Class A and B operators must be trained within 30 days of assuming duties • Class C operators must be trained before they assume their duties because they must be able to immediately respond to emergencies Retraining Class A and B operators are responsible for ensuring their UST systems are compliant. Generally, Class A and B operators need to be retrained if the UST systems they are responsible for are determined to be out of compliance. At a minimum, retraining must cover those areas the E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations implementing agency determines are out of compliance. Retraining must be completed within 30 days of the implementing agency’s final determination of noncompliance. This final UST regulation allows designated operators to take annual refresher training in lieu of retraining, as long as all training areas required by regulation are covered. Designated operators must be subject to the annual refresher training in place at the time of the violation. This final UST regulation also allows implementing agencies to waive the retraining requirement. Unless waived, Class A and B operators must complete retraining according to § 280.244. EPA recommends the waiver be in writing. In waiving the requirement, EPA expects the implementing agency to consider factors such as the severity and areas of noncompliance. For example, retraining should not be required for equipment found inoperative during an inspection if one of the following apply: The owner and operator was unaware of the problem and operation and maintenance records indicate the equipment was operating during the most recent test or inspection; or the owner or operator is aware of the problem and has scheduled a timely repair. In those instances where UST system noncompliance violations do not warrant retraining, EPA encourages implementing agencies to provide information about the compliance issue to Class A and B operators so they are able to return their facilities to compliance. This provides greater flexibility for UST owners and operators to meet the retraining requirement. This final UST regulation is consistent with EPA’s retraining requirement for noncompliance with significant operational compliance requirements and an annual refresher training allowance in our operator training grant guidelines for states. This final UST regulation addresses comments about the terms independent trainer and independent organization in the retraining requirement at § 280.244. In this section, EPA is requiring that a training program or comparable examination be developed, administered, or both by an independent organization, the implementing agency, or recognized authority. A recognized authority includes, but is not limited to, tribes recognized by the U.S. Department of Interior Bureau of Indian Affairs. The development, administration, or both by an independent organization applies to all training approaches (classroom, Internet based, testing, etc.) and provides sufficient control for the implementing agency to address conflict VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 of interest and other concerns during retraining. EPA considered requiring retraining when UST facilities change equipment, but decided this would be a significant burden on both the regulated community and implementing agencies. However, if an UST system is out of compliance because of an equipment change, EPA is requiring that UST owners and operators ensure Class A and B operators are retrained as discussed above. Documentation This final UST regulation requires owners and operators maintain records on currently designated Class A, B, and C operators, rather than records on all Class A, B, and C operators for the previous three years, as proposed. EPA is requiring owners and operators maintain basic information to document Class A, B, and C operators and confirm they are appropriately trained. For example, classroom training records must be signed by the trainer and include information about the training company; computer based training records do not require a signature, but must indicate the name of the training program and the Web address, if Internet based. This final UST regulation also modifies § 280.245(b)(1) by clarifying that the requirement for a record of training is also applicable when Class A or B operators train Class C operators. UST owners and operators must document verification of training or retraining for each class of operator. Owners and operators must maintain records verifying training or retraining as long as Class A, B, and C operators are designated at the facility. 2. Secondary Containment This final UST regulation adds new requirements for secondary containment and interstitial monitoring of new and replaced tanks and piping along with under-dispenser containment (UDC) of new dispenser systems. Data from release sites show a higher number of releases from single walled tanks and piping when compared to secondarily contained systems.11 12 These new requirements will prevent regulated substances from reaching the environment and ensure a consistent level of environmental protection for regulated UST systems across the United States. 11 Petroleum Releases At Underground Storage Tank Facilities In Florida, Peer Review Draft, US EPA/OUST, March 2005. 12 Evaluation Of Releases From New And Upgraded Underground Storage Tanks, Peer Review Draft, US EPA/OUST, August 2004. PO 00000 Frm 00009 Fmt 4701 Sfmt 4700 41573 The Energy Policy Act of 2005 requires implementing agencies, as a condition of receiving federal Subtitle I money, implement additional measures to protect groundwater. Under EPAct, implementing agencies’ choices to protect groundwater are: Secondary containment (including UDC); or financial responsibility for manufacturers and installers (and installer certification). All states are implementing or plan to implement secondary containment. The EPAct did not specifically require additional measures to protect groundwater in Indian country. To bring UST systems in Indian country to the same level of environmental protection as UST systems in states, this final UST regulation implements secondary containment requirements for new and replaced tanks and piping along with UDC underneath all new dispenser systems. The EPAct requires states that receive federal Subtitle I money (and choose the secondary containment option) to have secondary containment and UDC for tanks, piping, and dispensers only if they are installed or replaced within 1,000 feet of an existing community water system or potable drinking water well.13 However, EPA is requiring all new and replaced tanks and piping to install secondary containment and new dispenser systems to install UDC for these reasons: • Nearly all new and replaced tanks and piping are installed within 1,000 feet of an existing community water system (CWS) or potable drinking water well (PDWW). An UST listed with a commercial ownership type (i.e., gas station) is typically located within 1,000 feet of an on-site well or public water line because nearly all commerciallyowned facilities with USTs require water utilities in order to operate. In addition, privately owned facilities (i.e., fleet fueling for non-marketers) are generally in close proximity to some type of water supply, given that these sites are typically combined with other functional operations (office, maintenance, manufacturing, etc.) and require water for restrooms, water fountains, shops, etc.; 14 • Some implementing agencies that require secondary containment only 13 Title XV, Subtitle B, Section 1530 of Energy Policy Act of 2005, Public Law 109–58, August 8, 2005. 14 E2, Incorporated, memoranda and analyses submitted under Contract EP–W–05–018, U.S. Environmental Protection Agency. Underground Storage Tanks/Leaking Underground Storage Tanks Analytical And Technical Support. These supporting materials are located in the docket EPA– HQ–UST–2011–0301. E:\FR\FM\15JYR2.SGM 15JYR2 41574 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 within 1,000 feet of a CWS or PDWW informed EPA that installations of single walled tanks or piping are not occurring; and • Secondary containment for all new and replaced tanks and piping along with UDC for new dispenser systems will help protect other sensitive areas, such as designated source water protection areas, natural springs, and surface waters. The EPAct requires under-dispenser containment underneath new motor fuel dispenser systems at UST systems regulated under 40 CFR part 280. However, EPA is aware of a small number of dispenser systems, such as kerosene dispensers, that do not dispense motor fuel. Small releases can occur at these dispensers in the same manner as they occur at motor fuel dispensers.15 16 17 Therefore, this final UST regulation requires owners and operators install UDC underneath new dispenser systems at UST systems regulated under 40 CFR part 280, irrespective of whether they dispense motor fuel. The secondary containment requirement applies to new or replaced underground tanks and piping regulated under Subtitle I, except those excluded by regulation in § 280.10(b) and those partially excluded by regulation in § 280.10(c). Petroleum and hazardous substance USTs must meet the secondary containment requirement with the corresponding use of interstitial monitoring for release detection. The 1988 UST regulation allowed variances to the use of interstitial monitoring as the method of release detection for hazardous substance USTs. Since these variances are no longer an option, EPA is removing the language allowing variances for new installations from this final UST regulation. EPA is requiring owners and operators install tank and piping secondary containment that: Will contain regulated substances leaked from the primary containment until they are detected and removed; will prevent the release of regulated substances to the environment at any time during the operational life of the UST system; and is monitored for a leak at least once every 30 days using interstitial 15 Petroleum Releases At Underground Storage Tank Facilities In Florida, Peer Review Draft, US EPA/OUST, March 2005. 16 Evaluation Of Releases From New And Upgraded Underground Storage Tanks, Peer Review Draft, US EPA/OUST, August 2004. 17 Frequency And Extent Of Dispenser Releases At Underground Storage Tank Facilities In South Carolina (EPA–510–R–04–004, September 2004). https://epa.gov/oust/pubs/dispenser.htm. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 monitoring. These requirements are consistent with the requirements for secondarily contained hazardous substance tanks in § 280.42 and are necessary to help prevent releases to the environment. EPA is not requiring secondary containment for piping that meets the requirements of § 280.41(b)(2)(i) through (v), sometimes called safe suction piping, because such piping is currently not required to meet release detection requirements. Safe suction piping uses a suction pump to deliver regulated substances from the UST to the dispenser. Safe suction piping operates at less than atmospheric pressure, slopes towards the UST so regulated substances drain to the UST if suction is lost, and has only one check valve located close to the suction pump. As discussed in the 1988 UST regulation preamble, these characteristics ensure that little, if any, regulated substances will be released if a break occurs in the line.18 Similarly, EPA considers piping that manifolds two tanks together, which has characteristics that allow product to drain to the manifolded tanks if the piping loses suction, the same as safe suction piping. In addition, this final UST regulation does not require secondary containment for new and replaced piping associated with fieldconstructed tanks greater than 50,000 gallons in capacity and airport hydrant fuel distribution systems. See section C– 2 for additional information about these types of UST systems. EPA is not requiring secondary containment and UDC for UST systems where installation began on or before 180 days after the effective date of this final UST regulation. 180 days allows owners and operators who have concrete plans for a new UST system or dispenser installation to move forward with their plans before the secondary containment and UDC requirement takes effect. Similar to the definition of existing tank system in the 1988 UST regulation, EPA considers an installation to have begun after the owner or operator applied for or obtained all federal, state, and local approvals or permits and: • Physical construction or installation began; or • The owner or operator entered into a contractual agreement that cannot be cancelled or modified without substantial loss and physical construction or installation will commence within a reasonable time frame. 18 Preamble to 40 CFR part 280, 53 FR 37154, September 23, 1988. PO 00000 Frm 00010 Fmt 4701 Sfmt 4700 Requiring retrofits of major components would be a significant financial burden for owners and operators. EPA anticipates owners and operators will replace single walled UST systems as they age. When owners and operators replace single walled UST systems after the effective date of the final UST regulation, tanks and piping must be secondarily contained and new dispensers must have UDC. To implement secondary containment and UDC, EPA is adding new definitions to this final UST regulation. EPA is defining these terms so they are consistent with the definitions contained in EPA’s secondary containment grant guidelines to implementing agencies.19 New definitions in the final UST regulation are: • Dispenser—This means equipment located aboveground that dispenses regulated substances from the UST system. The 2011 proposed UST regulation defined dispenser system. However, based on comments received, EPA decided to also add the definition of dispenser to the final UST regulation. • Dispenser system—This means the dispenser and the equipment necessary to connect the dispenser to the UST system. As described above, EPA decided to add dispenser to the list of definitions in the final UST regulation for clarity. As a result, EPA shortened the definition of dispenser system in the final UST regulation to account for the new definition of dispenser. • Replaced—For a tank, this means to remove a tank and install another tank. For piping, it means to remove 50 percent or more of piping and install other piping, excluding connectors, connected to a single tank. For tanks with multiple piping runs, this definition applies independently to each piping run. Commenters suggested adding a definition of replaced as it applies to a dispenser system. However, since EPA is only applying the UDC requirement to new dispenser systems, we are not defining the term replaced as it relates to dispenser systems. • Secondary containment or secondarily contained—This means a release prevention and release detection system for a tank or piping. This system has an inner and outer barrier with an interstitial space that is monitored for leaks. This term includes containment sumps when used for interstitial monitoring of piping. The EPAct defines secondary containment as a release 19 Grant Guidelines to States for Implementing the Secondary Containment Provision of the Energy Policy Act of 2005: https://epa.gov/oust/fedlaws/ secondco.htm. E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 detection and prevention system that meets the interstitial monitoring requirement in § 280.43(g). Based on this definition, this final UST regulation includes interstitial monitoring as part of the secondary containment definition. Consistent with the 1988 UST regulation release detection requirements, EPA is requiring interstitial monitoring of new and replaced secondarily contained tanks and piping to occur at least once every 30 days. Some commenters expressed concern about whether secondary containment included containment sumps. To clarify the definition, EPA is adding language about containment sumps to the secondary containment definition. In addition, EPA is defining containment sump in this final UST regulation. See section B–4, Secondary Containment Tests, for details about this new definition. Several commenters suggested EPA add to the definition of secondary containment a 360 degree containment requirement for tanks. EPA relies on codes of practice developed by nationally recognized associations or independent testing laboratories to determine the degree of containment necessary to be considered secondarily contained. This final UST regulation continues to rely on these codes of practice for determining when the tanks and piping are considered secondarily contained. • Under-dispenser containment— This means containment underneath a dispenser system designed to prevent leaks from the dispenser and piping within or above the UDC from reaching soil or groundwater. Based on comments received and to provide clarification, EPA is adding piping in the containment sump to the definition. EPA’s secondary containment grant guidelines provide states with significant flexibility to define replaced as it applies to piping. The guidelines require that states, at a minimum, consider replacing piping when 100 percent of piping, excluding connectors, connected to a single UST is removed and other piping is installed. When deciding how to best define replaced as it applies to piping, EPA analyzed state UST regulations for approximately 40 states that currently require secondary containment and interstitial monitoring.20 About 75 percent of these states have requirements as stringent as, 20 E2, Incorporated, memoranda and analyses submitted under Contract EP–W–05–018, U.S. Environmental Protection Agency. Underground Storage Tanks/Leaking Underground Storage Tanks Analytical And Technical Support. These supporting materials are located in the docket EPA– HQ–UST–2011–0301. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 or more stringent than, the 50 percent threshold in this final UST regulation. In addition, EPA performed a screening analysis using limited, readily available data to determine when repair cost approached replacement cost (and at what point owners and operators were most likely to replace the entire piping run rather than repair it).21 The screening analysis suggested replacement cost of an entire piping run became equal to repair cost when about 60 percent of a piping run is repaired. Since 60 percent was an approximate screening number, EPA in this final UST regulation is requiring owners and operators to secondarily contain the entire piping run when 50 percent or more of a piping run is replaced. Fifty percent represents half of a piping run, is consistent with most implementing agency decisions, and provides flexibility for allowing repairs while continuing to protect the environment. Fifty percent also prevents owners and operators from leaving small pipe sections in the ground to avoid this secondary containment requirement. If an UST has multiple piping runs, the secondary containment requirement applies independently to each piping run where 50 percent or more of piping is replaced. Currently installed piping runs, and piping runs where less than 50 percent of the piping is repaired, do not require secondary containment. For pressurized piping, EPA considers a piping run to be the piping that connects the submersible turbine pump (STP) to all of the dispensers fed by that pump. For example, if a tank has two STPs, EPA considers the piping associated with each STP to be separate piping runs. For suction piping, a piping run is the piping that runs between the tank and the suction pump. Consistent with EPA’s current policy, if an owner or operator chooses to reinstall a secondarily contained tank or piping that was previously installed, that tank or piping must meet new tank and piping standards in § 280.20 at the time of installation. EPA is requiring owners and operators install UDC underneath new dispenser systems at UST systems regulated by 40 CFR part 280. Data from release sites show dispensers are one of the leading release sources.22 23 UDC is located underground and prevents some 21 Industrial Economics Incorporated, Work Assignment #1–19, Methodology and Calculator for Secondary Containment for Piping, October 3, 2008. 22 Petroleum Releases At Underground Storage Tank Facilities In Florida, Peer Review Draft, US EPA/OUST, March 2005. 23 Evaluation Of Releases From New And Upgraded Underground Storage Tanks, Peer Review Draft, US EPA/OUST, August 2004. PO 00000 Frm 00011 Fmt 4701 Sfmt 4700 41575 releases by containing small leaks that occur inside and underneath the dispenser. EPA considers a dispenser system new when owners and operators install both the dispenser and equipment needed to connect the dispenser to an UST system. EPA includes check valves, shear valves, unburied risers or flexible connectors, and other transitional components as equipment that connects a dispenser to an UST system. This equipment is located underneath the dispenser and typically connects underground piping to a dispenser. If an owner or operator replaces a dispenser but uses existing equipment to connect a dispenser to the UST system, then UDC is not required. To contain small releases from the dispenser, piping, and other equipment, UDC must be liquid tight. This final UST regulation requires UDC be liquid tight on its sides, bottom, and at any penetrations through the containment. EPA is requiring periodic testing of UDC in section B–4, Secondary Containment Tests, if the UDC is used for piping interstitial monitoring. In addition, EPA is requiring annual inspections of containment sumps in section B–1, Walkthrough Inspections, including UDC. Finally, an owner or operator must be able to access and visually inspect the containment. If visual inspection and access are not possible, then owners and operators must periodically monitor UDC (i.e., by electronic monitoring) to ensure it is intact and free of liquids. EPA proposed continuous UDC monitoring if visual inspection and access of the UDC are not possible. However, in guidance to state UST programs about meeting the secondary containment provision of the EPAct, EPA did not require continuous monitoring. Therefore, to provide owners and operators additional flexibility and be consistent with guidance provided to states, this final UST regulation requires periodic monitoring of UDC if access to and visual inspection of the UDC are not possible. B. Additional Requirements for Operation and Maintenance The 1988 UST regulation required owners and operators install improved UST system equipment to detect and prevent releases; however, it did not require operation and maintenance for all of that equipment. Owners and operators need to properly operate and maintain their UST system equipment in order to prevent and quickly detect releases. Therefore, this final UST regulation adds requirements for periodic walkthrough inspections, spill prevention equipment testing, overfill E:\FR\FM\15JYR2.SGM 15JYR2 41576 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations prevention equipment inspections, containment sump testing, and release detection equipment testing. When a test or inspection occurs, owners and operators may find problems with the UST system. When a test or inspection indicates a problem, owners and operators must repair the problem to remain in compliance with this final UST regulation. Section 280.33 of this final UST regulation describes repair requirements for UST systems. tkelley on DSK3SPTVN1PROD with RULES2 1. Walkthrough Inspections To help EPA determine whether walkthrough inspections will be effective, EPA asked nine states with requirements for periodic walkthrough inspections whether their requirements are effective.24 Seven states believe their programs are effective. Two states did not provide input because they had not been implementing their walkthrough inspection programs long enough to evaluate effectiveness. States providing input indicated their walkthrough inspections: Identify and resolve problems more quickly; decrease the chance of a potential spill or release; and increase understanding and compliance with the UST regulation. Based on this information and input received from comments on the 2011 proposed UST regulation, EPA thinks walkthrough inspections will be effective in helping prevent and detect releases. Based on comments EPA received, this final UST regulation requires owners and operators conduct walkthrough inspections as follows: • Every 30 days: Æ Visually check spill prevention equipment for damage and remove liquid or debris; check for and remove obstructions in the fill pipe; check the fill cap to ensure it is securely on the fill pipe; and, for double walled spill prevention equipment with interstitial monitoring, check for a leak in the interstitial area (exception: Owners and operators of spill prevention equipment at UST systems receiving deliveries at intervals greater than 30 days may check that equipment prior to each delivery) Æ Check release detection equipment to ensure it is operating with no alarms or unusual operating conditions present and ensure release detection records are reviewed and current • Annually: Æ Visually check containment sumps for damage and leaks to the containment area or releases to the environment; 24 Work Order No. 1004, Task 2, Subtask a—State Walkthrough Underground Storage Tank Inspections, SKEO, 1/31/2013 VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 remove liquid (in contained sumps) or debris; and, for double walled containment sumps with interstitial monitoring, check for a leak in the interstitial area Æ Check hand held release detection equipment, such as groundwater bailers and tank gauge sticks, for operability and serviceability In addition, this final UST regulation allows owners and operators to conduct operation and maintenance walkthrough inspections according to a standard code of practice developed by a nationally recognized association or independent testing laboratory or according to requirements developed by the implementing agency. The inspections must check equipment in a manner comparable to the walkthrough inspection requirements described above. This final UST regulation requires owners and operators maintain walkthrough inspection records for one year. Most commenters supported a one year recordkeeping requirement for walkthrough inspections. In addition, the one year recordkeeping time frame is consistent with the recordkeeping requirement for 30 day release detection monitoring. The walkthrough inspection record must include a list of each area checked, whether each area checked was acceptable or needed action taken, a description of actions taken to correct an issue, and delivery records if owners and operators check spill prevention equipment less frequently than every 30 days. In 2011, EPA proposed to implement the walkthrough inspection requirement on the effective date of the final UST regulation. However, based on comments received and to align implementation of all operation and maintenance requirements, owners and operators must begin conducting walkthrough inspections not later than three years after the effective date of this final UST regulation. This change will make compliance easier and allow owners and operators ample time to understand their walkthrough inspection responsibilities. In 2011, EPA proposed requiring owners and operators inspect containment sumps once every 30 days. Many commenters were concerned about inspecting containment sumps every 30 days because of the physical burdens of lifting heavy lids, the potential to ruin seals that prevent water from entering the sump, and the safety of the people performing the inspection in high traffic areas. While EPA thinks frequent containment sump inspections are a valuable part of UST system operation and maintenance, EPA PO 00000 Frm 00012 Fmt 4701 Sfmt 4700 recognizes the concerns raised by commenters and is moving the requirement to conduct containment sump inspections from once every 30 days to annual, which coincides with when owners and operators must open containment sumps to test release detection equipment. In the 2011 proposed UST regulation, EPA required that hand held release detection equipment be inspected once every 30 days. Based on commenter input, this final UST regulation requires annual inspections of hand held release detection equipment to coincide with other release detection equipment operation and maintenance requirements. In the 2011 proposed UST regulation, EPA required 30 day cathodic protection inspections as part of the walkthrough inspection. Several commenters indicated this frequency conflicted with the 60 day requirement already in the 1988 UST regulation. Based on this input, this final UST regulation keeps cathodic protection inspections at the 60 day interval as required in the 1988 UST regulation. Therefore, owners and operators must continue to perform the 60 day impressed current cathodic protection inspections to ensure equipment is running properly and keep the most recent three records of those inspections. The 2011 proposed UST regulation required checking monitoring and observation wells every 30 days to make sure they are secure. A few commenters questioned the need to perform these inspections because owners and operators seldom access these wells unless they are used for release detection or cleanup. EPA agrees with these commenters and also thinks that owners and operators will secure monitoring wells following each 30 day release detection monitoring event or during cleanups as part of their normal compliance activities. Therefore, EPA is not including monitoring and observation wells as part of the periodic walkthrough inspection requirement in this final UST regulation. EPA received several comments on the 2011 proposed UST regulation recommending treating nonretail UST systems differently than traditional commercial UST facilities because some nonretail UST systems receive infrequent deliveries. Based on the comments, this final UST regulation allows additional flexibility for inspecting spill prevention equipment at UST systems where filling occurs infrequently. In cases where filling activities occur less often than 30 days, owners and operators may inspect spill E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations prevention equipment prior to each delivery, instead of at least once every 30 days. This exception to the spill prevention equipment check for the 30 day walkthrough inspection requirement will still provide appropriate environmental protection because the purpose of this equipment is to catch drips and spills that may occur when the delivery hose is disconnected from the fill pipe. For UST systems receiving infrequent deliveries, inspecting spill prevention equipment before each delivery is adequate. This final UST regulation retains 30 day inspections of release detection equipment and spill prevention equipment. EPA thinks these inspections are needed at least once every 30 days for release detection to ensure the equipment is operating, check release detection records, and determine whether the tank or piping is leaking. Owners and operators who monitor their release detection system remotely may check the release detection equipment and records remotely as long as the release detection system at the UST system location is determined to be in communication with the remote monitoring equipment. In addition, 30 day inspections (or before each delivery) of spill prevention equipment will ensure these devices contain small drips and spills that occur when the delivery hose is disconnected from the fill pipe. Based on commenter input, EPA is adding the requirement to check for and remove obstructions in the fill pipe as part of the walkthrough inspection because obstructions in the fill pipe will cause a shutoff device to operate improperly. EPA is including Petroleum Equipment Institute’s Recommended Practice 900, Recommended Practices for the Inspection and Maintenance of UST Systems, as a code of practice that may be used to meet the walkthrough inspection requirement in this final UST regulation.25 This recommended practice includes daily, monthly, and annual inspections for properly maintaining underground storage tank systems. Owners and operators who use the code of practice option for meeting UST requirements must use the entire code of practice. For example, owners and operators would not meet the walkthrough inspection requirement if they chose to follow only some of the walkthrough inspection areas in the code of practice while ignoring others. This final UST regulation allows flexibility for owners and operators to conduct walkthrough inspections 25 This document is available for purchase at www.pei.org. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 themselves or hire a third party to conduct walkthrough inspections. Although EPA does not require training for owners and operators who conduct these inspections, operators trained in the Class A or B training requirements (see section A–1) should already have adequate knowledge to perform periodic walkthrough inspections. EPA received multiple comments suggesting we revise the 30 day inspection requirement to be a monthly requirement. After careful consideration, EPA is keeping the 30 day inspection requirement. Thirty days provides owners and operators with clarity about the inspection time frame by specifying the maximum number of days between walkthrough inspections. EPA is not moving to monthly inspections because owners and operators could misinterpret monthly and go 60 or more days without conducting a walkthrough inspection. For example, an owner or operator could perform a monthly inspection on January 31, then again on February 1, and then not inspect again until March 31. If an owner or operator continued this practice, six inspections would occur one day apart and six inspections would occur about 60 days apart. While this could be considered inspecting monthly, it is not inspecting consistently on or about the same time each month. EPA wants to ensure the walkthrough inspection frequency is consistent, rather than allow the more inconsistent monthly option in this example. Since 30 days is the average length of a month, EPA’s intent with requiring 30 days is to ensure owners and operators conduct walkthrough inspections on or about the same time each month. Some commenters raised concern about disposing of liquids owners and operators discover during the inspection. For spill prevention equipment and containment sumps to operate as intended, those areas must be free of liquids. In the past, when owners and operators found liquids in those areas, they needed to remove the liquids so the equipment would operate properly (and meet the 1988 UST regulation). This final UST regulation is requiring those areas be inspected periodically; as a result, owners and operators may discover the liquid sooner, but the responsibility to remove the liquid remains the same. EPA expects owners and operators to remove, manage, and dispose of the liquid properly (according to federal, state, and local requirements) as soon as practicable after discovery. PO 00000 Frm 00013 Fmt 4701 Sfmt 4700 41577 2. Spill Prevention Equipment Tests In this final UST regulation, EPA is adding a three year testing requirement for spill prevention equipment. This action helps ensure spill prevention equipment will contain small drips and spills when the delivery transfer hose is disconnected from the fill pipe. Owners and operators need to properly operate and maintain their spill prevention equipment in order to prevent releases to the environment. If a small release occurs at the fill port and the spill prevention equipment is not liquid tight, then the release can exit the spill prevention equipment and reach the environment. EPA is aware of various problems with spill prevention equipment. Data show that UST spills account for about 15 percent of releases from UST systems.26 27 Examples of problems with spill prevention equipment include damage due to: Vehicles driving over the spill prevention equipment; ground movement or freeze and thaw cycles; inadequate installation practices; and normal wear and tear. In addition, the typical life of spill prevention equipment is relatively short—five to eight years according to a South Carolina study.28 29 The life span for spill prevention equipment can be even shorter when exposed to more severe weather conditions such as freeze and thaw cycles and plowing following snow events. Because of these factors, periodic spill prevention equipment testing is needed to minimize problems and ensure spill prevention equipment will contain small releases from the delivery hose when disconnected from the fill pipe. This final UST regulation does not require periodic testing of double walled spill prevention equipment if the integrity of both walls is periodically monitored. Because the integrity of both walls is periodically monitored, this type of spill prevention equipment is periodically checked for tightness. In 2011, EPA proposed to exclude from the periodic testing requirement only double walled spill prevention equipment with continuous interstitial monitoring. Several commenters suggested that monitoring of the 26 Evaluation Of Releases From New And Upgraded Underground Storage Tanks, Peer Review Draft, US EPA/OUST, August 2004. 27 Petroleum Releases At Underground Storage Tank Facilities In Florida, Peer Review Draft, US EPA/OUST, March 2005. 28 Spill Bucket Performance Presentation by Dale Stoudemire, 2005 UST National Conference, March 14–15 2005, Seattle, WA. 29 Spill Buckets: Mistaken Expectations?, LUSTLine Bulletin 48, Dale W. Stoudemire, November 2004. E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 41578 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations interstitial area be used in lieu of periodic spill prevention equipment testing. EPA agrees with commenters that double walled spill prevention equipment, where the integrity of both walls is periodically monitored, should not have to undergo testing—as long as owners and operators conduct periodic monitoring of the equipment at a frequency consistent with, or more frequent than, the walkthrough inspection frequency (see section B–1). For example, owners and operators who check vacuum, pressure, or liquid interstitial integrity indicators on double walled spill containment devices as part of their 30 day walkthrough inspections are considered to be periodically monitoring the integrity of both walls. For spill prevention equipment that must be tested once every three years, this final UST regulation requires owners and operators to conduct testing using vacuum, pressure, or liquid methods. In addition, the test must be conducted in accordance with manufacturer’s requirements or a code of practice developed by a nationally recognized association or independent testing laboratory. The manufacturer’s requirement is an option only when the manufacturer has developed requirements for testing the tightness of their spill prevention equipment. As of the publication date of this final UST regulation, EPA is aware of one code of practice that contains procedures for testing spill prevention equipment: Petroleum Equipment Institute (PEI) Recommended Practice (RP) 1200, Recommended Practices for the Testing and Verification of Spill, Overfill, Leak Detection and Secondary Containment Equipment at UST Facilities.30 EPA is adding this code of practice to this final UST regulation. In addition, EPA is providing implementing agencies flexibility to allow other methods they determine to be as protective of human health and the environment as the manufacturer’s requirements or a code of practice. This option allows alternatives in case codes of practice and manufacturer’s requirements are not available for testing spill prevention equipment. Several commenters expressed concern that EPA did not establish specific pass or fail performance criteria for spill prevention equipment testing. EPA thinks the manufacturer, code of practice, or implementing agency are better suited to establish test method criteria because spill prevention devices are manufactured in different shapes and 30 This document is available for purchase at www.pei.org. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 sizes. Therefore, EPA is relying on the test method to establish specific pass or fail performance criteria. In 2011, EPA proposed a one year implementation time frame for owners and operators to begin conducting spill prevention equipment testing. However, based on commenter input suggesting implementation be consistent with other testing requirements, EPA is requiring owners and operators of spill containment equipment in use as of the effective date of this final UST regulation conduct the first test no later than three years after the effective date of this final UST regulation. EPA thinks aligning implementation dates for the different operation and maintenance testing requirements to the extent possible will provide clarity about the requirements owners and operators must meet. After the first spill prevention equipment test, owners and operators must test spill prevention equipment at least once every three years. For UST systems brought into use after the effective date of this final UST regulation, the spill prevention equipment testing requirement applies at installation. However, owners and operators must also follow the installation requirements in § 280.20(d) which require manufacturer’s instructions and installation standards be followed. These instructions and standards currently address liquid tightness of spill prevention equipment at installation. As long as the spill prevention equipment is tested and liquid tight at installation, the first periodic spill prevention equipment test does not have to be conducted until three years after installation. In 2011, EPA proposed that owners and operators test spill prevention equipment at least annually. However, based on comments received, EPA is requiring owners and operators test spill prevention equipment at least once every three years. Commenters suggested that all operation and maintenance testing should be aligned so that all tests can be conducted at the same time. EPA agrees. To make it easier for owners and operators to comply, this final UST regulation aligns periodic spill, overfill, and secondary containment testing to the extent possible. Since spill prevention equipment has a relatively short lifespan, EPA thinks a three year testing frequency, when combined with periodic visual checks via the walkthrough inspection (see section B– 1), is adequate to ensure spill prevention equipment will contain any drips or spills when the delivery hose is disconnected from the fill pipe. PO 00000 Frm 00014 Fmt 4701 Sfmt 4700 EPA received significant support for requiring owners and operators to keep records of the spill prevention equipment test for three years. This final UST regulation requires owners and operators maintain records of spill prevention equipment testing for three years for each spill prevention device at the facility. A three year period aligns with the maximum time between on-site UST facility compliance inspections. These records will demonstrate to implementing agencies that the spill prevention equipment was tested and tight at the time of the test. Owners and operators of UST systems with double walled spill prevention equipment, where the integrity of both walls is periodically monitored and who choose not to conduct spill prevention equipment testing at least once every three years, must maintain documentation showing that spill prevention equipment has two walls and the integrity of both walls is periodically monitored. Owners and operators must maintain this documentation for as long as the equipment is periodically monitored. Owners and operators who discontinue periodic monitoring of their double walled spill prevention equipment must conduct a test within 30 days of discontinuing the periodic monitoring. EPA considers this necessary because discontinuing periodic monitoring of the interstitial area may mean some portion of that area of the spill prevention equipment may no longer have integrity. Owners and operators need to ensure the primary containment of the spill prevention equipment is tight. Alternatively, owners and operators may choose to test double walled spill prevention equipment once every three years, and maintain the test record, in lieu of periodically monitoring this equipment and maintaining these monitoring records. Several commenters raised concerns about disposal of the spill prevention equipment test liquid following the test. EPA considered test liquid disposal in this final UST regulation and contacted several vendors to determine whether disposal of the test liquid was included as part of spill prevention equipment testing.31 Some vendors include handling of the test liquid as part of the test; they carry the test liquid with them and reuse it several times before disposal. Others charge a separate cost to dispose of the test liquid or make sure the owner or operator has drums on site to dispose of the test liquid. In addition, 31 Spill, Overfill, and Secondary Containment testing Questions and Answers from Three Vendors (11/8/12). E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 vendors sometimes use vacuum testing for spill prevention equipment testing, which eliminates the liquid from the test. A few commenters raised concerns about facility down time and replacement costs for spill prevention equipment as a result of testing. EPA acknowledges that, in instances where access to the spill prevention equipment is in the line of traffic, there could be a small amount of facility down time as a result of testing; however EPA thinks the benefit to the environment far outweighs the cost of potential down time. To minimize the effects of down time, owners and operators can also schedule the testing during low traffic times at the facility or when other routine maintenance occurs. EPA expects owners and operators to have properly functioning spill prevention equipment at all times and fix problems when they are discovered. The spill prevention equipment test may uncover a problem earlier, resulting in repair or replacement (and better protection from spills) sooner rather than later, and more quickly detect or prevent releases of regulated substances to the environment. 3. Overfill Prevention Equipment Inspections In this final UST regulation, EPA is adding periodic operation and maintenance requirements for overfill prevention equipment to help ensure the equipment is operating properly and will activate before an UST is overfilled. Owners and operators need to properly operate and maintain their overfill prevention equipment in order to prevent releases to the environment. If overfill prevention equipment is not working properly, an UST can be overfilled and release product to the environment. EPA is aware that USTs are being overfilled and there are problems with overfill prevention equipment. Data show that tank overfills account for about 15 percent of releases from UST systems.32 33 Examples of problems with overfill prevention equipment include: Tampering, improper use, and normal wear and tear. Overfill prevention equipment inspections will minimize problems and ensure overfill prevention equipment is operating properly. The 2011 proposed UST regulation used the term testing for overfill prevention equipment when describing 32 Petroleum Releases At Underground Storage Tank Facilities In Florida, Peer Review Draft, US EPA/OUST, March 2005. 33 Evaluation Of Releases From New And Upgraded Underground Storage Tanks, Peer Review Draft, US EPA/OUST, August 2004. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 the periodic functionality checks. However, based on input from commenters about potentially overfilling the tank during testing, EPA is using the term inspections—rather than testing—in this final UST regulation. The procedure to determine whether overfill prevention equipment is operating properly should not overfill the tank. Rather, the equipment must be inspected to determine whether it will operate or activate properly according to requirements in this final UST regulation. For example, the inspection to determine whether an automatic shutoff device in the fill pipe will activate at the correct height might involve removing and inspecting the device to ensure it operates as well as measuring the position of the device in the tank to ensure it activates at the appropriate level in the tank. For overfill prevention equipment inspections, owners and operators must use manufacturer’s requirements or a code of practice developed by a nationally recognized association or independent testing laboratory. Manufacturer’s requirements are an option only when manufacturers have developed inspection requirements for their overfill prevention equipment that determines the device is set to activate at the appropriate level in the tank and will activate when the regulated substance reaches that level. As of this final UST regulation, EPA is aware of one code of practice that contains procedures for inspecting overfill prevention equipment: PEI RP 1200, Recommended Practices for the Testing and Verification of Spill, Overfill, Leak Detection and Secondary Containment Equipment at UST Facilities.34 EPA added this code of practice in this final UST regulation. In addition, EPA is providing implementing agencies flexibility to allow other methods they determine to be as protective of human health and the environment as the manufacturer’s requirements or a code of practice. This option allows alternatives in case a code of practice and manufacturer’s requirements are not available for inspecting overfill prevention equipment. This final UST regulation requires owners and operators conduct overfill prevention equipment inspections at least once every three years. Commenters generally supported a three year or more frequent inspection cycle. EPA chose the three year time frame because it aligns with three year compliance inspections and is consistent with other operation and 34 This document is available for purchase at www.pei.org. PO 00000 Frm 00015 Fmt 4701 Sfmt 4700 41579 maintenance requirements, such as containment sump testing and spill prevention equipment testing. In 2011, EPA proposed to stagger implementation for overfill prevention equipment inspections over a three year period based on the installation date of the oldest UST at the facility. However, EPA received significant input from commenters opposing the phased in approach and advocating a single implementation date. EPA agrees with the merits of a more simplified approach. Therefore, for overfill prevention equipment installed as of this final UST regulation, owners and operators must conduct the first inspection within three years of the effective date of this final UST regulation. After the first overfill prevention equipment inspection, owners and operators must inspect overfill prevention equipment at least once every three years. For UST systems brought into use after the effective date of this final UST regulation, the overfill prevention equipment inspection requirement applies at installation. However, owners and operators must also follow the installation requirements in § 280.20(d) which require following manufacturer’s instructions and installation standards. These instructions and standards currently address the operability of the overfill equipment at installation. As long as the overfill prevention equipment is inspected for operability at installation, the first periodic overfill prevention equipment inspection does not have to be conducted until three years after installation. EPA received significant support for requiring owners and operators to keep records of overfill prevention equipment inspections for three years. The three year period aligns with the maximum time between on-site UST facility compliance inspections. Therefore, this final UST regulation requires owners and operators maintain for three years overfill prevention equipment inspection records for each overfill device at the facility. These records will demonstrate to implementing agencies that the overfill prevention equipment has been inspected, is set at the appropriate height in the tank, and will activate when regulated substances reach that height. Several commenters were concerned about potential damage to overfill prevention equipment during removal for inspection. EPA asked several vendors who perform overfill prevention equipment inspections about the potential for damage during periodic overfill prevention equipment E:\FR\FM\15JYR2.SGM 15JYR2 41580 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 inspections.35 The vendors indicated that seals may need to be replaced when removing the equipment, but that overfill prevention equipment itself would not easily be damaged during removal or reinstallation. The vendors also indicated that replacing these seals will result in little or no additional cost to the owner and operator. A few commenters raised concerns about facility down time and replacement costs for overfill prevention equipment as a result of periodic inspections. EPA acknowledges that, in instances where access to overfill prevention equipment is in the line of traffic, there could be a small amount of facility down time as a result of inspecting; however EPA thinks the benefit to the environment far outweighs the cost of potential down time. To minimize the effects of down time, owners and operators can also schedule the inspection during low traffic times at the facility or when other routine maintenance occurs. EPA expects owners and operators to have properly functioning overfill prevention equipment at all times and fix problems when they are discovered. The overfill prevention equipment inspection may uncover a problem earlier, resulting in repair or replacement (and better protection from overfills) sooner rather than later. 4. Secondary Containment Tests The 2011 proposed UST regulation included periodic secondary containment testing requirements for secondary containment areas of tanks and piping and for containment sumps used for monitoring the secondary containment areas of piping. However, based on the significant opposition commenters provided, this final UST regulation is not requiring periodic secondary containment testing of secondarily contained tanks and piping. EPA agrees with commenters who indicated secondarily contained UST systems using interstitial monitoring are more protective of the environment than single walled UST systems. In addition, EPA understands that some secondarily contained UST systems installed before this final UST regulation may not have been designed to have the interstitial areas periodically tested. Finally, EPA does not want to create a disincentive for owners and operators to replace older single walled UST systems with secondarily contained systems or penalize early installers of secondarily contained UST systems. However, this 35 Spill, Overfill, and Secondary Containment testing Questions and Answers from Three Vendors (11/8/12). VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 final UST regulation does require testing of these areas following a repair or, as appropriate, in response to a suspected release if they are used for interstitial monitoring. Interstitial areas where interstitial monitoring is used need to be tight following a repair so that the interstitial monitoring will detect a release before it reaches the environment. Likewise, interstitial areas need to be tested in response to a suspected release to determine whether a leak has reached the environment. EPA disagrees with commenters who suggested periodic testing for containment sumps used for interstitial monitoring of piping is unnecessary. These areas function similar to spill containment equipment, containing leaks from piping and other components in the sump. Containment sumps can degrade over time, resulting in releases to the environment. Information about source and cause of release shows that a significant number of releases occur in containment sump areas.36 37 Containment sumps have piping and other components that penetrate through the containment sump walls, increasing the likelihood that these areas are not liquid tight. Containment sumps used for interstitial monitoring of piping need to be liquid tight so they will contain regulated substances released from the primary wall of the piping. Therefore, this final UST regulation includes a three year testing requirement for containment sumps used for interstitial monitoring of piping. This final UST regulation does not require periodic testing of double walled containment sumps used for interstitial monitoring of piping if the integrity of both walls of the containment sump is periodically monitored. Because the integrity of both walls is periodically monitored, this type of containment sump is periodically checked for tightness. EPA proposed to exclude from the periodic testing requirement only containment sumps with continuous interstitial monitoring. Several commenters suggested that periodic monitoring (rather than continuous monitoring) of the interstitial area of the double walled containment sump would be adequate in lieu of performing the periodic containment sump testing. EPA agrees with commenters that double walled containment sumps, where the integrity of both walls is periodically monitored, 36 Petroleum Releases At Underground Storage Tank Facilities In Florida, Peer Review Draft, US EPA/OUST, March 2005. 37 Evaluation Of Releases From New And Upgraded Underground Storage Tanks, Peer Review Draft, US EPA/OUST, August 2004. PO 00000 Frm 00016 Fmt 4701 Sfmt 4700 should not have to undergo testing—as long as owners and operators conduct periodic monitoring of the equipment at a frequency consistent with, or more frequent than, the walkthrough inspection frequency (see section B–1). For example, owners and operators who check vacuum, pressure, or liquid interstitial integrity indicators on double walled containment sumps as part of their annual walkthrough inspections are considered to be periodically monitoring the integrity of both walls. This final UST regulation does not require periodic testing of containment sumps used for reasons other than interstitial monitoring of piping. Testing of these areas is not necessary to ensure the release detection will detect a leak because owners and operators are not using the containment sumps for interstitial monitoring. In these cases, owners and operators use another method of release detection and previously installed containment sumps as part of good business practice. Some commenters suggested EPA add definitions for continuous monitoring and interstitial monitoring. Since this final UST regulation uses the concept of periodic monitoring rather than continuous monitoring, EPA is not defining continuous monitoring. The concept of interstitial monitoring was used in the 1988 UST regulation and remains the same in this final UST regulation (see § 280.43(g)). In addition, this final UST regulation describes interstitial monitoring in detail in subpart D. Therefore, EPA is not further defining interstitial monitoring. Based on commenter input, EPA is adding to this final UST regulation a definition of containment sump, which addresses comments about what constitutes a containment sump. EPA considers a containment sump to be a liquid tight container that protects the environment by containing leaks and spills of regulated substances from piping, dispensers, pumps, and related components in the containment area. Containment sumps may be single walled or secondarily contained and located at the top of tank (tank top or submersible turbine pump sump), underneath the dispenser (underdispenser containment sump), or at other points in the piping run (transition or intermediate sump). This final UST regulation requires owners and operators conduct testing of containment sumps used for interstitial monitoring of piping at least once every three years. Commenters generally supported a three year or more frequent inspection cycle. EPA is choosing the three year time frame to: Make E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations compliance easier for owners and operators; align with three year compliance inspections; and be consistent with other operation and maintenance requirements, such as overfill prevention equipment inspections and spill prevention equipment testing. For containment sumps that require testing at least once every three years, this final UST regulation requires owners and operators conduct testing by using vacuum, pressure, or liquid methods. In addition, the test must be conducted in accordance with manufacturer’s requirements or a code of practice developed by a nationally recognized association or independent testing laboratory. The manufacturer’s requirement is an option only when the manufacturer has developed testing requirements for their containment sumps that ensure their containment sump is tight. As of this final UST regulation, EPA is aware of one code of practice that contains procedures for testing containment sumps: PEI RP 1200, Recommended Practices for the Testing and Verification of Spill, Overfill, Leak Detection and Secondary Containment Equipment at UST Facilities, and is adding this code of practice to the final UST regulation.38 In addition, EPA is providing implementing agencies flexibility to allow other methods they determine to be as protective of human health and the environment as the manufacturer’s requirements or a code of practice. This option allows alternatives in the event that a code of practice and manufacturer’s requirements are not available for testing containment sumps. Several commenters expressed concern that EPA did not establish specific pass or fail performance criteria for containment sump testing. However, EPA thinks the test method established by the manufacturer, code of practice, or implementing agency are better suited to establish criteria because containment sumps are made in different shapes and sizes. Therefore, EPA is relying on the test method to establish specific pass or fail performance criteria. In 2011, EPA proposed to stagger secondary containment testing implementation over a three year period, based on the installation date of the oldest UST at a facility.

Therefore, containment sumps used for interstitial monitoring of piping installed as of the effective date of this final UST regulation must be tested within three years of the effective date of this final UST regulation. After the first test, owners and operators must conduct periodic testing at least once every three years. For UST systems brought into use after the effective date of this final UST regulation, the containment sump testing requirement applies at installation. However, owners and operators must also follow the installation requirements in § 280.20(d) which require following manufacturer’s instructions and installation standards.

As long as the containment sump is tested and liquid tight at installation, the first periodic containment sump test does not have to be conducted until three years after installation. EPA received significant support for the three year recordkeeping time frame for secondary containment testing because the three year time period aligns with the maximum time between on-site UST facility compliance inspections. Therefore, this final UST regulation requires owners and operators maintain for three years containment sump testing records for each containment sump used for interstitial monitoring at a facility. These records will demonstrate to implementing agencies that containment sumps were tested and tight at the time of the test. Owners and operators who have double walled containment sumps where the integrity of both walls is periodically monitored and choose not to conduct containment sump testing at least once every three years must maintain documentation showing their containment sumps have two walls and the integrity of both walls is periodically monitored. Owners and operators must maintain this documentation for as long as the integrity of the two walls of the containment sump is periodically monitored. Owners and operators who discontinue periodic monitoring of their double walled containment sumps must conduct a test within 30 days of discontinuing the periodic monitoring. EPA considers this necessary because discontinuing periodic monitoring of the interstitial area may mean some portion of that area of the containment may no longer have integrity.

Alternatively, owners and PO 00000 Frm 00017 Fmt 4701 Sfmt 4700 41581 operators may choose to test double walled containment sumps (and maintain testing records) once every three years in lieu of maintaining these records. Several commenters raised concern about disposing of containment sump test liquid following the test. EPA considered test liquid disposal in this final UST regulation and contacted several vendors to determine whether they included disposal of test liquid as part of containment sump testing.39 Some vendors include handling of the test liquid as part of the test; they carry the test liquid with them and reuse it several times before disposal. Others charge a separate cost to dispose of the test liquid or make sure the owner or operator has drums on site to dispose of the test liquid. In addition, vendors could use vacuum testing for containment sump testing, which eliminates the liquid from the test. A few commenters raised concerns about facility down time and replacement costs for containment sumps as a result of testing. EPA acknowledges that, in instances where access to the containment sump is in the line of traffic, there could be a small amount of facility down time as a result of testing; however EPA thinks the benefit to the environment far outweighs the cost of potential down time. To minimize the effects of down time, owners and operators can also schedule the testing during low traffic times at the facility or when other routine maintenance occurs that requires opening containment sumps. EPA expects owners and operators to have properly functioning containment sumps at all times when those containment sumps are used for interstitial monitoring of piping and fix problems when they are discovered. The containment sump test may uncover a problem earlier than if a test was never conducted, resulting in repair or replacements of the containment sump (and better protection from releases) sooner rather than later. 5. Release Detection Equipment Tests This final UST regulation requires UST owners and operators perform annual operation and maintenance tests on electronic and mechanical components of their release detection equipment to ensure the equipment is operating properly. Owners and operators are required, at a minimum, to check this equipment: 39 Spill, Overfill, and Secondary Containment testing Questions and Answers from Three Vendors (11/8/12).

Changes include: • Noting that PEI RP 1200 may be used to meet the testing requirements • Increasing from one year to three years the time allowed for UST system owners and operators to implement the requirements • Using the term automatic line leak detector instead of line leak detector • Removing the leak sensing O-ring from the list of components tested • Adding handheld electronic equipment associated with vapor and groundwater monitoring EPA is concerned about the performance of release detection equipment. Inspectors routinely find release detection equipment installed on UST systems, but often that equipment is not properly operated or maintained. In addition, information from an analysis in Florida indicates that leak detection successfully detected 26 percent of all releases. Conversely, leak detection was specifically identified as failing to detect 23 percent of releases.40 To increase the effectiveness of release detection, this final UST regulation targets operation and maintenance. This final UST regulation requires that release detection is operated and maintained in accordance with manufacturer’s instructions, a code of practice, or requirements developed by the implementing agency. To achieve optimal performance from equipment and to meet release detection 40 Petroleum Releases At Underground Storage Tank Facilities In Florida, Peer Review Draft, US EPA–OUST, March 2005. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 requirements, it is important for UST system owners and operators to both install the equipment properly and properly operate and maintain it. In the 1988 UST regulation, EPA did not provide specifics on the minimum requirements to ensure adequate operation and maintenance of release detection equipment. As a result, manufacturer operation and maintenance requirements vary greatly, even among similar types of equipment. Some manufacturer’s requirements do not adequately address operation and maintenance. For example, some manufacturers only recommend operation and maintenance testing; but EPA is taking the position that testing should be mandatory instead of optional. In addition, similar release detection components should be tested in a similar manner, which will increase the likelihood all release detection equipment will function at optimal levels for as long as possible. California’s in field analysis of sensors used for release detection supports EPA’s position.41 This final UST regulation improves and standardizes operation and maintenance for all release detection equipment; it provides owners and operators with required equipment tests, which will help ensure equipment is properly operated and maintained. EPA is requiring a set of minimum operation and maintenance criteria that owners and operators must follow for electronic and mechanical based release detection equipment. The operation and maintenance minimum requirements for release detection established in This final UST regulation are based on common requirements and recommendations by various equipment manufacturers of similar equipment. EPA used the National Work Group On Leak Detection Evaluations’ (NWGLDE) list of leak detection equipment to identify commonly used equipment.42 In addition, EPA’s publication, Operating And Maintaining Underground Storage Tanks Systems: Practical Help And Checklists and PEI’s Recommended Practices for the Inspection and Maintenance of UST Systems (RP 900) also helped establish proper operation and maintenance activities. Owners and operators must meet the release detection operation and 41 California’s Field Evaluation Of Underground Storage Tank System Leak Detection Sensors, August 2002. https://www.waterboards.ca.gov/ water_issues/programs/ust/leak_prevention/ sensors/index.shtml. 42 National Work Group On Leak Detection Evaluations’ List Of Leak Detection Evaluations For Storage Tank Systems. https://www.nwglde.org/. PO 00000 Frm 00018 Fmt 4701 Sfmt 4700 maintenance requirements according to one of the following: Manufacturer’s instructions; a code of practice developed by a nationally recognized association or independent testing laboratory; or requirements determined by the implementing agency to be no less protective of human health and the environment than the two options listed above. These requirements are consistent with options for other operation and maintenance activities in this final UST regulation. As an example, see section B–2, Spill Prevention Equipment Tests. At the time of the 2011 proposed UST regulation, PEI was developing a code of practice, which EPA anticipated would address operability testing of release detection equipment. PEI issued the final recommended practice in 2012. EPA reviewed PEI’s final Recommended Practices for the Testing and Verification of Spill, Overfill, Leak Detection and Secondary Containment Equipment at UST Facilities (RP 1200) and is including it in this final regulation as an option for meeting the annual release detection equipment testing requirements.43 This final UST regulation requires owners and operators maintain records of the annual operation tests for three years. At a minimum, records must: List each component tested; indicate whether each component meets the criteria listed or needed to have action taken; and describe any action taken to correct an issue. The requirement to maintain records for three years is consistent with the three year compliance inspection cycle; maintaining records will allow owners and operators to demonstrate compliance with this operation and maintenance requirement. Based on comments received and EPA’s goal to align all implementation dates for consistency and easier compliance, this final UST regulation requires owners and operators meet operation and maintenance for release detection requirements no later than three years after the effective date of the final UST regulation. This is a change from the 2011 proposed UST regulation, which required that owners and operators meet this requirement no later than one year after the effective date of the final UST regulation. The 2011 proposed UST regulation used the term line leak detector as a component that must be tested. Based on comments received, this final UST regulation uses the term automatic line leak detector. This is consistent with 43 This document is available for purchase at www.pei.org. E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations how EPA has historically referenced line leak detectors in the 1988 UST regulation. These devices can be electronic or mechanical and are described in § 280.44(a). Commenters also asked EPA to add the performance criteria of 3 gallons per hour at 10 pounds per square inch line pressure to the simulated ALLD test required for the line leak detector. This is unnecessary since the 2011 proposed UST regulation required this performance standard for the simulated test by referencing § 280.44(a). This final UST regulation maintains that ALLDs, whether electronic or mechanical, must meet the annual simulated leak test of 3 gallons per hour at 10 pounds per square inch line pressure within 1 hour. One commenter noted his experience with testing release detection equipment, which verified electrical circuitry, but during operation the connected device still did not function to its intended precision. This commenter recommended EPA change the term test to functionality test. EPA thinks this change is unnecessary. The operation and maintenance requirements for release detection feature minimum performance criteria for testing. Each method used to meet the requirement (manufacturer’s instructions, a code of practice, or requirements developed by the implementing agency) must, at a minimum, cover each listed component and the stated performance criteria. EPA disagrees with the commenter who said EPA should allow selfdiagnostic equipment. Similar to the commenter in the previous paragraph, EPA is concerned that self-diagnostic equipment might verify electrical circuitry or communication, but not actually test equipment functionality. EPA requires testing to be performed in a manner that verifies equipment operation according to performance standards provided for each piece of release detection equipment. For example, testing ALLDs must involve simulating a system leak not greater than 3 gallons per hour at 10 pounds per square inch line pressure within 1 hour, or equivalent. ALLDs connected to ATG systems or other controllers may themselves be used to test electronic communication, but unless capable of simulating an appropriate leak in the system, do not meet the performance standard and, therefore, cannot be used to meet this requirement. In this final UST regulation, EPA is deleting language from the 2011 proposed UST regulation about inspecting and testing the leak sensing O-ring. Commenters requested EPA clarify what a leak sensing O-ring is. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 This O-ring is specific to the functional element of mechanical line leak detectors and is, therefore, only present on certain types of ALLDs. In addition, all functional elements will be tested as part of the simulated leak test conducted at 3 gallons per hour at 10 psi or equivalent for all ALLDs. This final UST regulation allows use of groundwater and vapor monitoring as methods of release detection, but with some restrictions (see section D–6). For owners and operators choosing groundwater or vapor monitoring as their method of release detection, this final UST regulation requires that hand held electronic devices such as photoionization devices meet the operation and maintenance requirements for release detection equipment. Non electronic hand held devices, such as measuring sticks and groundwater bailers, are covered in section B–1, Walkthrough Inspections. C. Addressing Deferrals This final UST regulation addresses airport hydrant fuel distribution systems and USTs with field-constructed tanks. In addition, this final UST regulation removes the release detection deferral for UST systems that store fuel solely for use by emergency power generators. As a result, these UST systems may no longer be subject to Spill Prevention, Control, and Countermeasure (SPCC) requirements. Finally, this final UST regulation partially excludes from Part 280 requirements wastewater treatment tank systems, UST systems containing radioactive material regulated under the Atomic Energy Act, and UST systems that are part of an emergency generator system at nuclear power generation facilities regulated by the Nuclear Regulatory Commission under 10 CFR part 50. To the extent these systems were regulated by the SPCC requirements, they will continue to be regulated by those requirements. In this final UST regulation, EPA partially excludes from part 280 requirements the aboveground storage tanks associated with airport hydrant fuel distribution systems and USTs with field-constructed tanks. These aboveground storage tanks are part of the UST system, but are excluded from most of this final UST regulation because they are not underground. At the time of the 1988 UST regulation, facilities with an aggregate completely buried storage capacity greater than 42,000 gallons and located near navigable waters of the United States or adjoining shorelines were subject to both UST regulations and SPCC regulations. Since then, the SPCC regulation has been amended and PO 00000 Frm 00019 Fmt 4701 Sfmt 4700 41583 exempts completely buried storage tanks, as well as connected underground piping, underground ancillary equipment, and containment systems when fully subject to the technical requirements of 40 CFR part 280. Partially excluded aboveground storage tanks which are part of the UST system may be subject to SPCC requirements. 1. UST Systems Storing Fuel Solely for Use by Emergency Power Generators— Require Release Detection This final UST regulation eliminates the deferral for UST systems storing fuel solely for use by emergency power generators (also referred to as emergency generator tanks). This means emergency generator tanks are no longer deferred from release detection requirements in 40 CFR part 280, subpart D and are subject to all UST requirements. This final UST regulation requires owners and operators of UST systems storing fuel solely for use by emergency power generators begin meeting these requirements: • For systems installed after the effective date of this final UST regulation, at the time of installation • For systems installed on or before the effective date of this final UST regulation, within three years of the effective date of this final UST regulation EPA is regulating UST systems storing fuel solely for use by emergency power generators because the rationale in the 1988 UST regulation for deferring release detection no longer applies. To allow time for developing workable release detection requirements, EPA in the 1988 UST regulation deferred release detection requirements for UST systems storing fuel solely for use by emergency power generators. The 1988 UST regulation preamble indicated that monthly monitoring requirements were unworkable because these tanks often were located at unmanned stations in remote areas and visited infrequently. EPA always intended for these systems to meet release detection requirements when appropriate release detection methods became available. Since the 1988 UST regulation, release detection technologies have matured greatly. In addition, technology is now available to perform release detection at remote sites. Emergency generator tanks can now be monitored for releases by the majority of methods listed in subpart D. EPA estimates about 30 percent of emergency generator tanks already have release detection. Effective remote monitoring methods for release detection are now available E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 41584 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations and currently used to monitor unmanned UST systems storing fuel solely for emergency generator tanks. Numerous companies perform remote monitoring for releases at these unmanned sites. When there is a suspected release, a remote monitor transmits a visual or audible alarm to a receiving console at a manned location. This provides owners and operators with real-time release detection data so owners and operators can quickly respond to suspected releases at sites with unmanned emergency generator tanks. Several commenters raised concerns that release detection methods may not properly operate on some emergency generator tanks and suggested changes to the release detection requirement. Commenters reported these issues: • Looped piping systems, which is piping configured to run continuously with integrated supply and return lines, cannot be properly isolated or does not have a sufficient quiet period to perform a precision test when using automatic tank gauging • Emergency generator tanks with copper piping may pose issues with meeting the release detection requirement due to system configurations • Most emergency generator tanks are single walled and are limited to automatic tank gauging as the form of release detection • Emergency generator tanks with day tanks and aboveground piping may need anti-siphon valves Other commenters suggested EPA limit the type of release detection, such as statistical inventory reconciliation (SIR), owners and operators may use on emergency generator tanks and that EPA should require owners and operators install electronic line leak detectors, which have a positive system shutdown of any product flow in the event of a leak. Other commenters recommended EPA clarify that automatic line leak detectors can go to alarm mode only and not shut down or restrict product flow when a leak is suspected in emergency generator tanks used during a crisis. EPA agrees that not all release detection methods may be suitable for all configurations of emergency generator tanks. EPA discussed the applicability of SIR on emergency generator tanks in general with several SIR vendors and received conflicting responses. A challenge to performing release detection is establishing a usage rate of product based on the run time of the system during operation. Although EPA thinks it is difficult to achieve accurate results, we do not have enough VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 information at this time to determine that SIR or other methods that rely on metered data are unacceptable for use on emergency generator tanks. Owners and operators must carefully consider whether these methods meet the release detection requirement for their UST systems. To meet the release detection requirement, some systems may require reconfiguration and addition of components such as anti-siphon valves to separate sections of the system. Some emergency generator tanks use safe suction piping, in which case release detection for piping is not required. However, release detection technologies have advanced since EPA issued the 1988 UST regulation and there are now various options available to meet this requirement. EPA understands some commenters want to require owners and operators to install automatic line leak detectors, which only shut off at the STP or allowing only certain release detection methods for these systems. However, to provide flexibility to owners and operators while continuing to protect human health and the environment, this final UST regulation allows owners and operators to choose the most appropriate release detection methods, including automatic line leak detectors that trigger an alarm only and not necessarily shut down the pump, for their systems. For an unmanned facility, the alarm must be transmitted to a monitoring center where someone can hear or see the alarm and quickly respond to a suspected release. One commenter suggested EPA define what is mission critical as it relates to emergency generator tanks. While EPA acknowledges the need for operating emergency generator tanks during an emergency, we think it is unnecessary to define the term mission critical or make exceptions for the release detection requirement for these tanks. The concern is that owners and operators of these systems should not have to shut down their systems during an emergency if they encounter a suspected release. EPA understands this concern but thinks owners and operators can perform release detection and respond to suspected releases while continuing to operate the UST system. Emergency generator tanks are located throughout the country. EPA’s review of several state databases revealed these systems are located at hospitals, universities, communication utilities, military installations, and other locations relying on backup power sources. Based on information from these databases, EPA estimates UST systems storing fuel solely for use by emergency power generators represent PO 00000 Frm 00020 Fmt 4701 Sfmt 4700 approximately 3 percent of the active tank population. Additionally, about 20 states currently require release detection for emergency generator tanks. Automatic tank gauging and secondary containment with interstitial monitoring are the most common release detection methods used for emergency generator tanks. Line tightness testing, automatic line leak detectors, or secondary containment with interstitial monitoring are the most common release detection methods used for piping. With technology now available to detect releases from emergency generator tanks and because they pose a risk to human health and the environment, this final UST regulation removes the deferral from release detection. The 2011 proposed UST regulation required owners and operators meet the release detection requirement within one year of the effective date of the final UST regulation. Several commenters raised concerns that a one-year time frame to meet this requirement is insufficient for owners and operators to assess, budget, and install release detection. Commenters also wanted EPA to establish a single implementation date, which is consistent with effective dates for release detection on other previously deferred tanks. EPA agrees that extending the time frame will allow owners and operators sufficient time for planning and installing necessary equipment to meet the release detection requirement; but we disagree with commenters who suggested a five to ten year implementation date. EPA also agrees that establishing a single effective date, which is consistent with other effective dates for the release detection requirement, decreases the tracking burden on implementing agencies as well as owners and operators. Based on support for increasing the final implementation date for release detection from one year and EPA’s goal of aligning regulatory implementation dates to make compliance easier for owners and operators, EPA is requiring owners and operators of emergency generator tanks installed on or before the effective date of this final UST regulation to meet the release detection requirement within three years of the effective date of this final UST regulation. Emergency generator tanks installed after the effective date of this final UST regulation must meet the release detection requirements when installed. The 2011 proposed UST regulation required that no later than 30 days after the effective date of the final UST regulation, owners of UST systems storing fuel solely for use by emergency E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations power generators notify implementing agencies that their systems exist. Commenters stated that this requirement is unnecessary because the 1988 UST regulation excluded emergency generator tanks from only the release detection requirement. EPA agrees with commenters. This final UST regulation does not include this onetime notification requirement for emergency generator tanks. 2. Airport Hydrant Fuel Distribution Systems and UST Systems With FieldConstructed Tanks This final UST regulation removes the 1988 deferral and requires owners and operators of airport hydrant fuel distribution systems (referred to as airport hydrant systems) comply with applicable requirements. However, EPA is tailoring the requirements to the unique nature of airport hydrant systems. Airport hydrant systems function and are designed differently than conventional USTs. Unlike conventional USTs, airport hydrant systems consist of networks of large diameter underground piping operating at high pressures to deliver fuel to aircraft. In addition, operation and maintenance requirements for airport hydrant systems may differ from those for conventional UST systems. This final UST regulation removes the 1988 deferral and requires owners and operators of UST systems with fieldconstructed tanks comply with applicable requirements. Similar to airport hydrant systems, EPA is tailoring the requirements to the unique nature of field-constructed tanks. UST systems with field-constructed tanks (referred to as field-constructed tanks) range from conventional sizes to very large capacities greater than 2 million gallons. A few commenters suggested EPA write regulations specifically for airport hydrant systems and field-constructed tanks, since they are distinctly different from conventional USTs. EPA agrees that airport hydrant systems and fieldconstructed tanks are different from conventional USTs. Additionally, EPA thinks it would help owners and operators if the requirements for airport hydrant systems and field-constructed tanks are in a separate subpart of the final UST regulation. In order to help owners and operators of these systems comply, this final UST regulation adds subpart K (UST Systems with FieldConstructed Tanks and Airport Hydrant Fuel Distribution Systems) and places most regulatory requirements for both airport hydrant systems and fieldconstructed tanks in one location. Since 1988, owners and operators of these systems have been required to comply with the requirements for subparts A (Program Scope and Interim Prohibition) and F (Release Response and Corrective Action for UST Systems Containing Petroleum or Hazardous Substances). This final UST regulation requires airport hydrant systems and fieldconstructed tanks installed on or before the effective date of the final UST regulation begin meeting the requirements of subpart K according to the schedule below. Airport hydrant systems and field-constructed tanks installed after the effective date of this final UST regulation must meet the requirements at the time of installation. Requirement Effective date Upgrading UST systems, general operating requirements, and operator training. Release detection ..................................................................................... Release reporting, response, and investigation; closure; financial responsibility and notification, except as provided in § 280.251(2)(b). tkelley on DSK3SPTVN1PROD with RULES2 This final UST regulation modifies the 2011 proposed UST regulation by revising the definition of airport hydrant fuel distribution system and defining a field-constructed tank. An airport hydrant fuel distribution system (also called airport hydrant system) is defined as an UST system which fuels aircraft and operates under high pressure with large diameter piping that typically terminates into one or more hydrants (fill stands). The airport hydrant system begins where fuel enters one or more tanks from an external source, such as a pipeline, barge, rail car, or other motor fuel carrier. A field-constructed tank is defined as a tank constructed in the field. For example, a tank constructed of concrete that is poured in the field, or a steel or fiberglass tank primarily fabricated in the field is considered field-constructed.

Release Prevention This final UST regulation requires airport hydrant systems and fieldconstructed tanks meet corrosion protection, spill, overfill, and walkthrough inspection requirements. Corrosion protection installed on airport hydrant systems and field-constructed tanks must meet either: • New tank and piping standards described in § 280.20, except that new and replaced hydrant piping and piping associated with fieldconstructed tanks greater than 50,000 PO 00000 Frm 00022 Fmt 4701 Sfmt 4700 gallons need not be secondarily contained or • Airport hydrant systems and fieldconstructed tanks installed on or before the effective date of the final UST regulation must either meet the corrosion protection upgrade requirements in § 280.252(b)(1) or the new tank and piping standards described above Airport hydrant systems and fieldconstructed tanks installed on or before the effective date of the final UST regulation that are not upgraded according to § 280.252(b) within three years of the effective date of the final UST regulation must be permanently closed according to subpart G.

Owners and operators must install the equipment and conduct the first spill test and overfill inspection no later than three years after the effective date of this final UST regulation and every three years thereafter. For airport hydrant systems brought into use after the effective date of this final UST regulation, spill and overfill prevention equipment requirements must be met at installation. Owners and operators must conduct walkthrough inspections that meet the requirements of § 280.252(c). Owners and operators must conduct the first inspection within three years after the effective date of the final UST regulation. In addition to the items inspected as part of the walkthrough inspection for other regulated UST systems, owners and operators of airport hydrant systems must inspect hydrant pits and hydrant piping vaults every 30 days for areas that do not require confined space entry according to the Occupational Safety and Health Administration (OSHA) and annually for areas that do require confined space entry. Owners and operators must keep documentation of the inspection according to § 280.36(b). Notification This final UST regulation requires owners and operators of regulated airport hydrant systems and fieldconstructed tanks meet these notification requirements: • For airport hydrant systems and fieldconstructed tanks currently installed, owners and operators must submit no later than 3 years after the effective date of this final UST regulation a one-time notification to their implementing agency that their systems exist • For airport hydrant systems and fieldconstructed tanks installed after the effective date of the final UST regulation, owners and operators must provide their implementing agency a notification of each newly installed system within 30 days of bringing each system into use • Owners must provide their implementing agency a notification of ownership change for each newly acquired airport hydrant system or field-constructed tank within 30 days of the date on which the new owner assumes ownership Financial Responsibility This final UST regulation requires owners and operators of airport hydrant systems and field-constructed tanks that have not been permanently closed meet VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 the financial responsibility requirements in subpart H at the time the one-time notification of existence is submitted to the implementing agency. Owners and operators who install these systems after the effective date of this final UST regulation must meet the financial responsibility requirements at installation. This requirement does not apply to state or federal owners of airport hydrant systems and fieldconstructed tanks. Partially Excluded Components This final UST regulation excludes aboveground storage tanks associated with airport hydrant systems and fieldconstructed tanks from the requirements of subparts B, C, D, E, G, J, and K. Owners and operators are still required to comply with subparts A (Program Scope and Installation Requirements for Partially Excluded UST Systems); and F (Release Response and Corrective Action for UST Systems Containing Petroleum or Hazardous Substances) for these tanks. Operator Training This final UST regulation requires owners and operators of airport hydrant systems and field-constructed tanks meet the operator training requirements in subpart J. Closure Requirements for Previously Closed Tanks When directed by the implementing agency, owners and operators of airport hydrant systems and field-constructed tanks permanently closed before the effective date of this final UST regulation must assess the excavation zone and close the UST system according to subpart G if releases from the UST may, in the judgment of the implementing agency, pose a current or potential threat to human health and the environment. Background Tanks and piping associated with airport hydrant systems and fieldconstructed tanks can store millions of gallons of fuel and handle large volumes of regulated substances on a daily basis. Leaks from these systems can contaminate subsurface soil beneath the airport apron and runways, groundwater, and nearby surface water systems, posing a significant risk to human health and the environment. As a result, EPA is removing the deferral. Some commenters indicated EPA needed to justify that airport hydrant systems and field-constructed tanks are leaking in order to regulate them. The 1988 UST regulation required owners and operators report only confirmed PO 00000 Frm 00023 Fmt 4701 Sfmt 4700 41587 releases from these tanks to implementing agencies. Owners and operators were not required to report suspected releases to implementing agencies, which sometimes resulted in gaps for ensuring proper site investigations or transmission of sufficient release information. As a result, implementing agencies have little to no available historical records regarding releases of regulated substances from airport hydrant systems and field-constructed tanks. In the 2011 proposed UST regulation, EPA provided details on several releases that previously occurred at airport hydrant systems. Since that time, EPA identified additional information on releases from both DoD and commercial airport hydrant systems. For example, at Hartsfield Jackson International Airport in Georgia, active remediation and free product recovery is ongoing (as of 2014) due to a 1988 release of an estimated 14,000 gallons of jet fuel.44 In 2003, an estimated 100,000 gallons of jet fuel leaked from the valves and flanges of an airport hydrant system at MinneapolisSt. Paul International Airport in Minnesota. Some of the jet fuel was released into the sanitary sewer and nearby waterway. During the investigation of the jet fuel release, personnel discovered a second jet fuel leak at a different concourse; this leak impacted the stormwater system and produced oily sheens in the Minnesota River. Responsible parties agreed to pay civil penalties and complete environmental projects, including continued site remediation and fuel recovery.45 In 1983 at Camp Lejeune, North Carolina, investigators discovered multiple feet of free product while using a hand auger to investigate the cause of a fuel inventory discrepancy.46 In addition, from the 1960s to the 1980s, thousands of gallons of jet fuel leaked from a former airport hydrant system at Pope Air Force Base, North Carolina. At one time, it was noted that as much as 75,000 gallons of free product was floating on top of the groundwater because of these releases. As of 2014, the site is undergoing remediation.47 In addition, at Marine Corps Air Station Cherry Point, North Carolina there have been multiple releases from the airport 44 Corrective Action Plan—Part B: HartsfieldJackson International Airport, Concourse Pit.

The station was cited twice in the 1990s for contaminating soil and groundwater under this fuel facility due to leaking tanks or fuel spills. An extensive environmental remediation effort is underway in 2014 to clean this site. Contamination from many of the releases combined and migrated to form a single plume. In the 2011 proposed UST regulation, EPA also provided details on several previous releases that occurred from field-constructed tanks. Since that time, EPA identified additional anecdotal information on releases from fieldconstructed tanks. At Adak Island, Alaska’s Tank Farm A, records show fuel was released at various times from 21,000 to 420,000 gallon fieldconstructed tanks and piping. As of 2014, all tanks have been removed, but the former fuel farm is still undergoing remediation through long term monitoring and monitored natural attenuation.48 Also at Adak Island, an overfill during a fuel transfer caused 142,800 gallons of diesel fuel to leak from a 4.8 million gallon underground field-constructed tank into the immediate and surrounding environment, causing harm to native wildlife.49 Releases can have a major impact on human health and the environment. Release prevention equipment, regular release detection tests, operator training, periodic walkthrough inspections, and proper operation and maintenance are keys to preventing and quickly identifying releases before they contaminate the surrounding environment. This final UST regulation adds these requirements for airport hydrant systems and field-constructed tanks in order to help prevent and quickly detect leaks from these systems into the environment. Definition of an Airport Hydrant System The 1988 UST regulation did not provide a definition for airport hydrant system. In the 2011 proposed UST regulation, EPA provided a definition of an airport hydrant system to clarify what components would be regulated. However, that definition was based on an airport hydrant system that received fuel at a single delivery point, designed with all components operating in tandem, and included only the immediate piping and tank directly feeding the airport hydrant piping. To clarify for owners and operators, EPA 48 Tank Farm A https://dec.alaska.gov/ Applications/SPAR/CCReports/Site_ Report.aspx?Hazard_ID=686. 49 https://www.darrp.noaa.gov/northwest/adak/ pdf/ADAK_DARPEA_FINAL_Draft%20PDF.pdf. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 presented scenarios of typical airport hydrant systems in a guidance document provided during the public comment period. After publishing the 2011 proposed UST regulation, EPA met with stakeholders to gather more information on airport hydrant system design and operation.50 51 EPA also provided another iteration of the schematics that contained better defined airport hydrant system scenarios. However, some commenters still were confused about which specific components of an airport hydrant system would be regulated.52 Many commenters requested that EPA provide guidance on how to perform the calculations to determine whether the airport hydrant system meets the definition of an underground storage tank and requested clarification of system components. In response to these comments, EPA is providing guidance below. In order for an airport hydrant system to be subject to the final UST regulation, it must first meet the definition of an underground storage tank. Airport hydrant systems are not regulated UST systems under 40 CFR part 280, unless 10 percent or more of the total capacity of the system is beneath the surface of the ground. When performing the calculation, include all tanks and underground piping that are part of the airport hydrant system. An airport hydrant system may have one or more of the following connected together: Aboveground tanks, underground tanks, field-constructed tanks, or factory constructed tanks. Below are two examples. Note that aboveground piping is not included when calculating the total volume. Example 1: A 1 million gallon aboveground storage tank (AST) connected to underground piping with a capacity of 100,000 gallons does not meet the definition of an UST, as explained below: 1 million gallons (AST) + 100,000 gallons (underground pipe) = 1.1 million gallons total volume 1.1 million gallons × 10% = 110,000 gallons The volume of the underground piping (100,000 gallons) is less than 10 percent of the total volume of the tanks and underground piping (110,000 gallons). 50 January 28, 2012, March 29, 2012, and October 19, 2012 meetings with representatives from Airlines for America. 51 February 28, 2013 and March 18, 2013 meetings with DoD’s Defense Logistics Agency Energy. 52 Airport Hydrant Systems Scenarios Revised, dated February 28, 2012. PO 00000 Frm 00024 Fmt 4701 Sfmt 4700 Example 2: A 2 million gallon AST feeds two 100,000 gallon fieldconstructed underground storage tanks and two 50,000 gallon underground tanks constructed in the factory which feed 100,000 gallons of underground hydrant piping. Calculating these values yields a total system capacity of 2,400,000 gallons with 400,000 gallons underground. More than 16% of this airport hydrant system is underground making it an UST. In response to comments on the proposed definition, EPA is clarifying the definition of an airport hydrant system in this final UST regulation. EPA determined that multiple tanks grouped or interconnected together can function as one system to fuel an airport hydrant system. EPA agrees with commenters that it would not be feasible to separate these tanks to define an airport hydrant system. EPA also found that other tanks not directly connected to the underground airport hydrant piping also could feed the airport hydrant system. The Agency is concluding that an airport hydrant system may consist of interconnected aboveground and underground storage tanks (that could be constructed in the factory or fieldconstructed) and piping that function as integral and interchangeable components of the fueling system. Field-constructed tanks that are part of the airport hydrant system are treated as part of the airport hydrant system and not independent UST systems that are field-constructed. The airport hydrant system begins when regulated substance enters from an external source such as a pipeline, barge, rail car, or other motor vehicle carrier, but does not include the external source. Airport hydrant systems use large diameter piping and operate at pressures higher than those of a conventional UST. This final definition alleviates stakeholder uncertainty on which components of an airport hydrant system must meet the UST regulation by including all integral components that form an airport hydrant system and deliver fuel to the aircraft. These systems include underground piping and ASTs or USTs that hold aircraft fuel (for example, settling tanks or product recovery tanks). They do not include tanks or underground piping not storing aircraft fuel (for example, additive tanks) or tanks and underground piping not connected to the airport hydrant system (for example, a system that fuels an emergency power generator for a pump house). In addition, EPA is aware there may be instances where an airport hydrant system might include permanently installed dispensing E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 equipment at the end of the hydrant piping instead of a fill stand. However, since these systems still operate under high pressure and contain large diameter piping, we consider them to be airport hydrant systems. Definition of a Field-Constructed Tank The preamble to the 1988 UST regulation described a field-constructed tank as a tank usually constructed of steel or concrete and shaped like flat vertical cylinders, with a capacity of greater than 50,000 gallons. Tanks that are primarily factory built, but assembled in the field, are considered factory built tanks. For example, welding two halves of a factory constructed tank together in the field does not qualify the tank as a fieldconstructed tank. Several commenters requested EPA define field-constructed tank in the final UST regulation in order for implementing agencies and owners and operators to know which tanks are applicable. While EPA thinks this term is self-evident, this final UST regulation defines field-constructed tank as a tank constructed in the field. For example, a tank constructed of concrete that is poured in the field, or a steel or fiberglass tank primarily fabricated in the field is considered field-constructed. Please note this definition excludes those tanks with components primarily manufactured in a factory with minimal assembly in the field. EPA considers those tanks are factory built tanks. Field-constructed tanks vary from sizes smaller than 50,000 gallons to sizes very large in capacity. Large capacity tanks may exceed size or shape limitations that prohibit transportation of the tank in whole to the UST site. Fieldconstructed tanks present an engineering, design, or transportation concern that cannot be addressed by fabrication in a factory or are more ideally addressed through in-field construction. This definition includes tanks that are mounded or partially buried, such as those defined in 40 CFR part 112, if 10 percent or more of the volume of the system is beneath the ground’s surface or otherwise covered with earthen material. EPA considers a field-constructed tank that is part of a wastewater treatment system to be partially excluded from the final UST regulation according to § 280.10(c). See section C–3 for additional information on the partial exclusion for wastewater treatment tank systems. Universe of Field-Constructed Tanks and Airport Hydrant Systems Affected UST systems with field-constructed tanks are generally very large and, in the event of a release, pose a substantial VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 threat to human health and the environment. Typical tank sizes range from 20,000 gallons to greater than 2 million gallons. EPA is aware of approximately 330 UST systems with field-constructed tanks owned by the Department of Defense and 12 fieldconstructed tanks owned by the Department of Energy (DOE). One commenter objected to EPA regulating airport hydrant systems because the 2011 proposed UST regulation addressed airport hydrant systems at military facilities and did not include systems at commercial airports. When issuing the 2011 proposed UST regulation, EPA thought the universe of these systems was mainly owned by DoD, based on information from DoD and commercial airport representatives. The 2011 proposed UST regulation also assumed the universe included two commercial airports with airport hydrant systems. Airlines for America (A4A, formerly known as Air Transport Association of America, Inc.) provided additional information during the public comment period that suggested nine commercial airports would be affected by the final UST regulation. As a result of the comments received, EPA did extensive research to confirm which commercial airports might be affected by the final UST regulation. EPA met with personnel from DoD and from eight of the nine suggested commercial airport facilities to gather additional information and determine the universe of airport hydrant systems that would have to comply with the final UST regulation.53 54 55 56 Additionally, EPA listened to concerns and answered questions about the 2011 proposed UST regulation. EPA also met with release detection vendors to determine whether commercial airports and DoD facilities could achieve release detection compliance within the specified time frames.57 58 59 EPA concluded that of the nine airports A4A named, eight would possibly be affected by the final UST regulation. Based on these meetings, 53 Discussions With Commercial Airports That May Be Affected By The Final UST Regulation dated February 6, 2013. 54 Note that EPA did not meet with personnel from Indianapolis International Airport however, A4A and vendors stated that the airport hydrant system is equipped with the necessary equipment to meet requirements in the final UST regulation. 55 January 28, 2013 and March 29, 2012 meetings with A4A. 56 February 28, 2013 and March 18, 2013 meetings with DoD’s Defense Logistics Agency Energy. 57 June 20, 2012 and May 19, 2013 meeting with Hansa Consult of North America, LLC. 58 June 20, 2012 meeting with VISTA Precision Solutions. 59 August 15, 2012 meeting with Ken Wilcox and Associates. PO 00000 Frm 00025 Fmt 4701 Sfmt 4700 41589 EPA found that most of the commercial airport hydrant systems have release prevention and detection equipment currently installed on them and airport personnel are already performing various activities that can be modified to meet the final UST regulation. Process for Obtaining Public Comment One commenter suggested that EPA: • Did not follow all requirements to allow stakeholder input prior to issuing the 2011 proposed UST regulation • Did not allow stakeholders adequate time to provide comments • Failed to follow the correct public notice procedures • Failed to inform stakeholders of two commercial airports that might be affected by the final UST regulation • May have led commercial airport stakeholders to doubt that any commercial airport hydrant systems would be affected by the final UST regulation The commenter also suggested EPA should withdraw the 2011 proposed UST regulation because the administrative record and resulting proposal conflicted with Executive Order 13563 (Improving Regulation and Regulatory Review).60 EPA disagrees with these comments. We performed extensive stakeholder outreach both prior to developing the 2011 proposed UST regulation and during the public comment period. In addition, EPA followed procedures required by the Administrative Procedure Act for providing public notice and requesting public comment through the Federal Register. In order to allow additional time for airport authorities to perform a preliminary assessment and respond to the 2011 proposed UST regulation, EPA extended the public comment period by two months as requested by commenters.61 EPA met with all interested stakeholders who requested meetings, including representatives of commercial airports. EPA carefully researched information provided during the public comment period; this included verifying methods of release detection currently 60 On January 18, 2011, President Obama issued Executive Order 13563, which directed federal agencies to develop a preliminary plan which outlined the agency’s approach for periodically reviewing regulations to determine whether any rules ‘‘should be modified, streamlined, expanded, or repealed so as to make the agency’s regulatory program more effective or less burdensome in achieving the regulatory objectives.’’ 61 January 5, 2012 request from A4A for a 60-day extension for more time to review and query its membership and potentially affected airports for a more complete understanding of the 2011 proposed UST regulation and potential costs. E:\FR\FM\15JYR2.SGM 15JYR2 41590 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations in use at commercial airports and DoD facilities, as well as what methods would be technically feasible at those facilities. When issuing the 2011 proposed UST regulation, EPA thought Lambert-St. Louis International Airport and Denver International Airport were the only commercial airports that would be affected by the final UST regulation. EPA identified these airports in a meeting with Airlines for America. During that meeting, the Agency also received additional information on other airports possibly affected by the proposal.62 While EPA did not specifically identify the two commercial airports that would potentially be affected by the final UST regulation, the 1988 UST regulation has been in effect for over two decades and portions of it have applied to airport hydrant systems since that time. Owners and operators of these systems have been required to comply with those applicable portions of the UST regulation since 1988, and it has been the responsibility of owners and operators to determine whether their airport hydrant systems are regulated since the effective date of the 1988 UST regulation. Nonetheless, EPA stated in the 2011 proposed UST regulation that airport hydrant systems are ‘‘. . . mainly owned by the Department of Defense (DoD) . . .,’’ not that DoD is the sole owner of all airport hydrant systems. This statement indicates there are non-DoD owned airport hydrant systems that could be affected by this final UST regulation. tkelley on DSK3SPTVN1PROD with RULES2 Impacts of Regulating Airport Hydrant Systems and Field-Constructed Tanks Commenters generally supported removing the deferral for these systems. However, there were some commenters who opposed regulating these systems. A few commenters were concerned about the costs for owners and operators to comply with the release detection requirements of the final UST regulation. EPA acknowledges that some release detection methods may result in additional costs to owners and operators. However, EPA carefully researched current release detection efforts at commercial airports and DoD facilities and used that information to estimate costs. See the RIA, which is available in the docket for this action, for additional information about how we estimated costs. Other Regulations That Affect Airport Hydrant Systems and Field-Constructed Tanks To avoid overlapping regulations, several commenters suggested EPA 62 January 28, 2012 meeting with A4A. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 evaluate other requirements that owners and operators of airport hydrant systems and field-constructed tanks perform as part of fuel management programs. One commenter also asserted that this evaluation was necessary to comply with Executive Order No. 13563.63 After issuing the 2011 proposed UST regulation, EPA performed this evaluation by gathering information on fuel management programs (such as release prevention, repairs, operation and maintenance, inspections, and operator training) owners and operators at these facilities must perform in order to meet other federal, state, and industry regulations.64 For example, EPA found that requirements administered by the Federal Aviation Authority (FAA), such as 14 CFR part 139 (Certification of Airports), and directives, such as ATA 103 and United Facilities Criteria (UFC) 3–460–03, require owners and operators of airport hydrant systems inspect airport hydrant systems and connected components. EPA also found that 14 CFR part 139 (Certification of Airports) emphasizes overall airport safety practices. One commenter asked whether EPA evaluated the SPCC requirements for regulating underground portions of airport hydrant systems. Another commenter suggested that EPA evaluate the effectiveness of existing state requirements for field-constructed tanks.65 EPA is aware that commercial airports and DoD facilities comply with SPCC requirements for their airport hydrant systems and field-constructed tanks. However, UST and SPCC regulations are complementary. The SPCC regulation focuses on oil discharges that could impact navigable waters, while the UST regulation focuses mainly on day-to-day maintenance and operation to prevent releases to soil and groundwater. For example, the SPCC regulation requires a tank inspection, such as an American Petroleum Institute (API) Standard 653 inspection, which ensures aboveground storage tanks and piping are structurally sound. In addition, regulatory overlap is 63 Executive Order 13563 requires federal agencies to avoid implementing unnecessary redundant requirements and promulgate regulations that are less burdensome to the regulated community. 64 EPA performed an assessment of the following additional requirements that owners and operators follow: 40 CFR part 112 (SPCC); 14 CFR part 139 (FAA); A4A 123; ATA 103; ATA O&M Guidance; UFC 3–460–1 [Proposed UST Requirements Compared To Existing Facility Requirements And Recommended Practices]. 65 New York allows owners and operators to perform a modified American Petroleum Institute Standard 653 inspection combined with monitoring well release detection for large field-constructed tanks. PO 00000 Frm 00026 Fmt 4701 Sfmt 4700 mitigated by the SPCC regulation, which allows UST release detection as a method to meet its tank inspection requirement. The SPCC regulation requires owners and operators conduct integrity and leak testing of buried piping at the time of installation, modification, construction, relocation, or replacement, but does not specify a method, frequency, or leak rate. The UST regulation is more specific and requires periodic release detection testing of underground piping. EPA thinks that other regulatory programs (such as SPCC and FAA) lack the necessary specificity or do not meet equivalency criteria we deem are necessary for these UST systems. Additionally, even though some A4A documents provide many recommended practices that owners and operators of airport hydrant systems and fieldconstructed tanks may follow for their fuel management programs, these practices are not regulatory requirements, and airports have the option of following them. Moreover, EPA developed a final UST regulation that is cost effective to the extent practical and is the least burdensome to owners and operators, yet still protects human health and the environment. This final UST regulation does not impose redundant requirements. Rather, it contains complementary requirements that will protect human health and the environment. Effect on Airport Operations One commenter suggested the requirements in the 2011 proposed UST regulation were not legally or technically viable for commercial airports. That commenter said EPA should develop a separate regulation specific to commercial airport hydrant systems. In addition, a few commenters were concerned that removing the deferral for airport hydrant systems would cause service disruptions due to installing release prevention and detection equipment. Those commenters also said performing release prevention and detection would cause massive service delays, affect military missions, and threaten national security and the National Airspace System. Based on discussions with DoD prior to issuing the 2011 proposed UST regulation and talking to DoD and potentially affected airports after issuing it, EPA concluded that most facilities already have the necessary equipment to meet many of the requirements in the final UST regulation. EPA also concluded from those conversations that release detection is normally performed during service downtimes or when E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 operations are minimal. Some airport hydrant systems have the capability of transferring product flow to other sections of the airport hydrant system to avoid system downtime. DoD stated that leak testing is performed according to prescribed requirements in Florida and California and at least biennially in other states when funding allows. Where feasible, piping is normally tested in segments to meet testing leak rates; piping segments can be isolated to find leaks more efficiently. EPA learned that some airport hydrant systems are capable of bypassing areas when airport hydrant piping is being tested; this avoids total system shutdown and allows continued airport operation. In addition, many airport personnel perform daily operations and maintenance activities, such as hydrant pit inspections and leak monitoring, on airport hydrant system components to avoid product loss, ensure fuel quality, and ensure personnel safety. This final UST regulation incorporates many of those tasks that operators normally perform regularly to prevent and detect leaks from these systems. However, to meet the final UST regulation, owners and operators may need to make minor modifications to their current activities. Since many airports have mechanisms in place and are already performing release monitoring, meeting requirements in the final UST regulation will not severely affect airport operations or cause service delays severe enough to significantly affect the military mission or disrupt the National Airspace System. EPA concluded that the information we gathered since issuing the 2011 proposed UST regulation supports regulating these systems as required in the final UST regulation. In addition, this final UST regulation includes changes to ensure compliance requirements are less disruptive and further mitigate concerns regarding service disruptions, such as adding options owners and operators may use to meet the release detection requirement. Implementation Time Frame EPA is aware that this final UST regulation adds new requirements for owners and operators, as well as implementing agencies which have not fully regulated airport hydrant systems and field-constructed tanks in the past. A few commenters voiced concerns that the proposed implementation time frames would not give owners and operators, or implementing agencies, adequate time to assess these systems and determine the proper course of action. EPA thinks providing a single VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 effective date is important because it reduces the burden on implementing agencies, owners, and operators to track various compliance deadlines. EPA is also allowing owners and operators who use periodic tightness testing for certain piping to phase in release detection requirements up to seven years. Additionally, EPA thinks three years gives owners and operators sufficient time for planning and installing necessary equipment to meet the requirements in this final UST regulation. Other Comments Commenters generally supported changing the applicability date for previously closed systems of airport hydrant systems and field-constructed tanks, giving implementing agencies the flexibility to require a site assessment and proper closure of systems closed between the effective date of the 1988 UST regulation and this final UST regulation. EPA agrees with commenters. As a result, this final UST regulation requires owners and operators of field-constructed tanks and airport hydrant systems, which were permanently closed before the effective date of this final UST regulation, to conduct a site assessment and close the UST system according to the closure requirements if directed to do so by the implementing agency. In the 2011 proposed UST regulation, EPA asked commenters if we should consider alternative options for closing very large UST systems in place. Most commenters recommended that large field-constructed tanks either be removed or filled with an inert solid material to prevent releases of residual contamination to the environment. Others suggested EPA allow some flexibility when closing these UST systems in place. EPA agrees with commenters that implementing agencies may need to have more flexibility in addressing these systems at closure. EPA is modifying the closure requirement in § 280.71(b) of the final UST regulation to allow closure in place in a manner approved by the implementing agency. This addition provides implementing agencies the option to determine that owners and operators may close the UST system in place without filling it with an inert solid material. One commenter recommended that EPA, in the final UST regulation, directly reference the military construction standard associated with field-constructed tank design and construction discussed in the preamble to the 2011 proposed UST regulation. EPA agrees with the commenter and is PO 00000 Frm 00027 Fmt 4701 Sfmt 4700 41591 adding the military construction criteria UFC 3–460–01—Petroleum Fuel Facilities to this final UST regulation.66 Although design standards are now available for aboveground fieldconstructed tanks, EPA is not aware of standards written according to a national code of practice developed by a nationally recognized or independent testing laboratory for non-military fieldconstructed tanks and airport hydrant systems. If demand arises and a commercial standard is not developed to address the need, owners and operators may use the UFC, where applicable. Release Detection Background In the preamble to the 1988 UST regulation, EPA discussed the large volumes of product throughput, large capacities, and long lengths of large diameter piping for airport hydrant systems. At the time, EPA believed release detection was not feasible for airport hydrant systems. These systems were monitored for releases periodically, but no single leak test existed as an industry standard. Inventory control was often used, but its sensitivity was limited due to the large product volumes airport hydrant systems typically handle. To allow more time for gathering information, EPA in the 1988 UST regulation deferred regulating airport hydrant systems from release detection requirements in subpart D. EPA also deferred UST systems with field-constructed tanks from most requirements in the 1988 UST regulation, due to a lack of appropriate release detection methods. At that time, EPA believed the majority of release detection methods applied to factory built tank systems and did not adequately work for UST systems with field-constructed tanks or airport hydrant systems. Challenges of Conventional Release Detection Methods Standard release detection methods can successfully test and detect releases on pressurized piping at commercial service stations, but that is not the case for airport hydrant systems and large diameter piping associated with fieldconstructed tanks. For a variety of reasons, the piping of most airport hydrant systems and field-constructed tanks cannot meet release detection 66 UFC 3–460–01—Petroleum Fuel Facilities is a military construction criteria that includes basic requirements for the design of fueling systems; the design of receiving, dispensing, and storage facilities; ballast treatment and sludge removal; corrosion and fire protection; and environmental requirements. E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 41592 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations requirements in the 1988 UST regulation. High product throughput makes it difficult and expensive to achieve the same leak rate thresholds established for traditional UST systems within a reasonable time frame. Product temperature fluctuations present challenges for release detection testing of conventional underground piping. However, release detection for piping of airport hydrant systems and large diameter piping associated with fieldconstructed tanks poses greater challenges. As temperatures fluctuate, product expands or contracts, increasing or decreasing product volume and pressure. The magnitude of piping associated with these systems creates an even greater temperature fluctuation; there are varying temperature gradients throughout the length of piping. Fluctuating line pressure during a release detection test can mask an existing release or falsely indicate one occurred. In addition, the out of service period needed to test airport hydrant piping could range from one to several days after the last product transfer. Removing airport hydrant systems from service for extended periods will greatly impede their purpose of rapid and timely delivery of fuel to aircraft. When using pressure based testing methods to produce accurate leak test results, airport hydrant system piping needs to be isolated in appropriately sized segments. Some airport hydrant systems have numerous isolation points with connections for release detection equipment. Others have longer underground piping segments with isolation valves for testing located up to 0.5 miles apart. The greater the volume of a segment, the more time it takes to obtain a valid result at a given leak rate. Although technology is available, it may be cost prohibitive and require significant facility down time for owners and operators to monitor airport hydrant systems for releases at the rates and frequencies required in the 1988 UST regulation. EPA also recognizes that most release detection methods for factory built tanks are capable of monitoring UST systems with field-constructed tanks up to 50,000 gallons. After evaluating current methods, EPA realized existing release detection options for tanks in subpart D of the 1988 UST regulation are generally not applicable to UST systems greater than 50,000 gallons because most methods are limited by tank capacity. EPA acknowledges the complexities in performing release detection on tanks significantly larger than 50,000 gallons. It is critical to allow sufficient time for a tank to reach a state of equilibrium prior to performing a test. As tank size VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 increases, the time for a tank to reach an equilibrium increases significantly. Based on discussions with release detection vendors, many larger tanks require multiple inactive days to yield an accurate test result. DoD owns most UST systems with field-constructed tanks. Taking these tanks out of service for multiple days to meet the 1988 release detection requirement would, in some cases, impede DoD’s mission, be impractical to sustain, and result in significant costs. Release Detection Is Now Available While release detection used for conventional USTs may not work well for airport hydrant systems and fieldconstructed tanks greater than 50,000 gallons, release detection methods specifically designed for these UST systems are now available. Over the last 25 years, the petroleum services industry has developed release detection technologies for airport hydrant systems and field-constructed tanks. The NWGLDE lists Large Diameter Line Leak Detection Method (6 Inches Diameter Or Above) and Bulk Underground Storage Tank Leak Detection Method (50,000 Gallons Or Greater), both of which identify methods capable of detecting releases from airport hydrant systems and fieldconstructed tanks.67 EPA contacted several vendors to determine the strengths and limitations of release detection methods for these UST systems. EPA also talked with DoD’s Defense Logistics Agency (DLA) Energy 68 about challenges in addressing release detection requirements in states, such as California, which do not defer airport hydrant systems from release detection. Because they perform release detection on airport hydrant systems in other states, DLA Energy has significant information about airport hydrant system release detection. As of this final UST regulation, some state UST programs require release detection for UST systems with field-constructed tanks and airport hydrant systems.69 67 National Work Group On Leak Detection Evaluation’s List Of Leak Detection Evaluations For Storage Tank Systems. https://www.nwglde.org/. 68 Defense Logistics Agency Energy was formerly known as Defense Energy Support Center. 69 Tasks 2–4, Work Assignment 1–25: Preliminary Assessment and Scoping of Data Related to Potential Revisions to the UST Regulations; Industrial Economics (IEc) Inc. identified 17 state UST programs that regulate airport hydrant systems. EPA’s Office of Underground Storage Tanks gathered additional information from seven of nine select state UST programs to identify the extent of the state’s release detection requirements and compare those requirements to the release detection requirements in EPA’s proposed 2011 UST regulation. PO 00000 Frm 00028 Fmt 4701 Sfmt 4700 Feasibility of Proposed Release Detection Options for Piping In order to allow owners and operators flexibility to meet the release detection requirement, EPA proposed these four alternatives for underground piping associated with airport hydrant systems and field-constructed tanks greater than 50,000 gallons: • Pressure based line testing methods • Continuous interstitial monitoring • Automatic line leak detector combined with interstitial monitoring and • Other methods approved by implementing agencies EPA requested comment or additional data on the proposed release detection requirements to determine their feasibility. Several commenters said the options in the 2011 proposed UST regulation were insufficient and requested EPA provide options that offered owners and operators more choices. A4A provided EPA with the names of nine commercial airports that could be affected by the final UST regulation and the feasibility of applying the release detection methods discussed in the 2011 proposed UST regulation to these airports. This information helped EPA further refine this final airport hydrant system requirements, including release detection. A4A stated that the only feasible choice EPA provided was pressure based methods and substantial retrofits would be required to meet the requirements at Chicago O’Hare International Airport (ORD), John F. Kennedy International Airport (JFK), and possibly other airports. However, EPA through our analysis and in depth discussions with those airports, thinks the airport hydrant system at JFK, as currently configured, may not meet the definition of an UST in this final UST regulation; this means the requirements would not apply. In addition, if planned capital upgrades are completed on one of ORD’s airport hydrant systems, that system may not meet the definition of an UST and would not be subject to this final UST regulation. If configurations for either of these airport hydrant systems change in the future, the owner and operator must re-evaluate the system to determine if it meets the definition of UST in this final UST regulation. Owners and operators are responsible for determining whether their airport hydrant systems meet the definition of an UST and, if necessary, comply with this final UST regulation. As a result of comments and while developing the final UST regulation, EPA met with DoD, A4A, personnel E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations representing potentially impacted commercial airports, and release detection vendors to develop release detection methods for the final UST regulation and determine how or if commercial airports and DoD facilities could achieve compliance within the specified time frames.70 71 72 73 74 From those discussions, EPA found that most, if not all, of the potentially affected commercial airports have or will have mechanisms in place to achieve compliance with the release detection requirements in this final UST regulation. In addition, owners and operators already implement release detection according to technical requirements in states where airport hydrant systems are not deferred. EPA found that many of these airport hydrant systems perform a type of inventory management and hydrostatic testing of the piping system to detect pressure changes in the UST system. EPA determined that although the 1988 UST regulation did not require airport hydrant system owners and operators perform these tests, both DoD facilities and commercial airports have already been performing various fuel management methods to monitor and track fuel inventories. Release Detection Options for Piping in the Final UST Regulation tkelley on DSK3SPTVN1PROD with RULES2 Based on comments, EPA is providing flexibility for owners and operators of piping associated with airport hydrant systems and field-constructed tanks greater than 50,000 gallons to meet the release detection requirements. This final UST regulation modifies the piping release detection options in the 2011 proposed UST regulation and incorporates some of the methods currently used at commercial airports and DoD facilities. Owners and operators of these systems may use existing piping release detection options provided in subpart D (except for passive groundwater and vapor monitoring, which must be combined with inventory control as described below), or they may use alternative piping release detection methods in § 280.252(d)(2). EPA thinks these options are reasonable and represent an appropriate balance of practicality and 70 January 28, 2012 and March 29, 2012 meetings with representatives from Airlines for America. 71 February 28, 2013 and March 18, 2013 meetings with DoD’s Defense Logistics Agency Energy. 72 June 20, 2012 and May 19, 2013 meeting with Hansa Consult of North America, LLC. 73 June 20, 2012 meeting with VISTA Precision Solutions. 74 August 15, 2012 meeting with Ken Wilcox and Associates. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 protectiveness. Piping associated with field-constructed tanks 50,000 gallons or less in capacity must use the release detection options listed in subpart D. Pressure Based Testing The final UST regulation allows owners and operators to perform pressure based testing methods according to performance criteria dependent on volume of the line segment tested. These criteria provide specific performance thresholds for both semiannual and annual testing. Owners and operators may perform semiannual or annual line testing at or above operating pressure with a probability of detection of 0.95 and a probability of false alarm of 0.05. This method allows owners and operators to meet a variable leak rate based on piping test section volume. The leak rate ranges from 1 to 3 gallons per hour, depending on piping volume for semiannual testing and from 0.5 to 1.5 gallons per hour for annual testing. The final UST regulation establishes 3 gallons per hour as the maximum threshold because the majority of available testing methods are capable of meeting this leak rate. For the first six years (or two test periods), piping segments that cannot meet a 3 gallons per hour threshold are allowed to meet a higher threshold of up to 6 gallons per hour. Available methods are capable of testing segments to a leak rate of 6 gallons per hour. The higher threshold provides for use of existing test methods during the first six year period. Six years will provide owners and operators time to upgrade their piping systems to meet the up to 3 gallons per hour threshold for semiannual testing. Between years six and seven, owners and operators must conduct one additional tightness test that, at a minimum, meets the semiannual testing threshold. In the seventh year, owners and operators must begin meeting the semiannual or annual line tightness testing requirements according to the requirements in § 280.252(d)(2)(i). EPA is providing a three year phase-in period for the remaining release detection options, because these methods will not require significant construction or upgrades for implementation. EPA asked commenters whether other release detection options should be considered for underground piping associated with airport hydrant systems and field-constructed tanks greater than 50,000 gallons. Based on comments, EPA is adding inventory control, groundwater and vapor monitoring, and other methods for piping as release detection options in this final UST regulation. PO 00000 Frm 00029 Fmt 4701 Sfmt 4700 41593 Inventory Control EPA reviewed performance standards for daily inventory control procedures used by DoD and the commercial airports identified by A4A.75 76 Based on performance standards for daily inventory control procedures performed by both DoD and A4A, EPA is allowing inventory control as part of a combination method of release detection. EPA chose 0.5 percent of flow through as the performance standard for inventory control because this value represents the maximum tolerance allowed under the performance standard for products typically stored or handled by airport hydrant systems. Owners and operators may conduct inventory control according to DoD Directive 4140.25, ATA’s Airport Fuel Facility Operations and Maintenance Guidance Manual, or equivalent procedures. EPA is allowing this method in combination with either a pressure based line tightness test using the leak rates from the semiannual test in § 280.252(d)(2)(i) at least once every two years, or passive groundwater or vapor monitoring once every 30 days as described below. Groundwater and Vapor Monitoring EPA proposed to phase out groundwater and vapor monitoring as release detection methods in the 2011 proposed UST regulation. However, this final UST regulation retains these methods with modifications. See section D–6 for more information. These methods are also allowed with some modifications in subpart K. EPA divided vapor monitoring into two categories: Active monitoring for chemical markers or tracers and passive monitoring for stored product in the tank system. Owners and operators of these systems 75 DoD’s Bulk Petroleum Management Policy— DoD 4140.25–M, Volume II—Petroleum Management, Chapter 10—Accountability (June 22, 1994) is accessible on line at: https://www.dtic.mil/ whs/directives/corres/pdf/414025-m-vol2chapter10.pdf. This standard recognizes that petroleum products are subject to losses and gains. The tolerance factor that represents the amount of fuel which might be lost or gained under normal conditions varies by product and status of fuel (i.e., storage or in transit). These values in the policy represent standard tolerances (i.e., system flowthrough) for various products in transit and storage: (1) Aviation and motor gas = 0.5 percent and 0.5 percent; (2) JP4 = 0.5 percent and 0.3 percent; (3) Jet Fuel, Distillates, Residuals = 0.5 percent and 0.25 percent; and (4) JP5, JP8, DF2, F76, etc. = varies by individual agreements with airports and 0.5 percent. 76 EPA reviewed Airlines For America Guidance—ATA Airport Fuel Facility Operation and Maintenance Guidance Manual, Revision 2004.1; and ATA Spec 123: Procedures for the Accounting of Jet Fuel Inventory 2011.2. The two documents provide guidance for operators to investigate, report, or explain any variances exceeding ±0.1 percent. E:\FR\FM\15JYR2.SGM 15JYR2 41594 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations may use active vapor monitoring methods characterized by testing or monitoring of chemical markers or a tracer compound placed in the tank system, according to § 280.43(e) to detect a release of at least 0.1 gallon per hour with probabilities of detection and false alarm of 0.95 and 0.05, respectively. Owners and operators choosing this option must conduct this test at least once every two years. This method may be used as a stand-alone method of release detection. Owners and operators may also combine passive vapor or groundwater monitoring with inventory control, described above, that can detect a release of at least 0.5 percent of flow through at least every 30 days. Passive vapor monitoring or groundwater monitoring must be conducted at least every 30 days according to § 280.43(e) or (f), respectively. tkelley on DSK3SPTVN1PROD with RULES2 Other Methods for Piping The final UST regulation maintains the option for owners and operators to use alternative methods of release detection for piping approved by the implementing agency, as discussed in the 2011 proposed UST regulation. This provides flexibility for owners and operators to comply by using methods or a combination of methods equivalent to the requirements in § 280.252(d)(2). EPA recognized that other methods not included in § 280.252(d)(2) could be acceptable, as long as they are as effective and are approved by implementing agencies. The performance criteria for piping release detection methods in § 280.252(d)(2) provide owners and operators with information about how to demonstrate the effectiveness of release detection methods that must be approved by the implementing agency. Proposed Release Detection Options for Piping Not Included in the Final UST Regulation Because piping segments associated with airport hydrant systems and fieldconstructed tanks can contain large volumes of regulated substances, EPA asked commenters if it was feasible to require ALLDs to detect a leak at 3 gallons per hour at 10 pounds per square inch line pressure within one hour or equivalent. EPA anticipated receiving information on the appropriate leak rate for ALLDs on this piping. EPA did not receive any indication that current performance standards of ALLDs could be modified for these systems. Although some portions of existing systems may be able to use this option, EPA agrees it is not feasible to use an ALLD with interstitial VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 monitoring on piping associated with airport hydrant systems and fieldconstructed tanks. This final UST regulation modifies the 2011 proposed UST regulation; owners and operators of airport hydrant systems or piping associated with fieldconstructed tanks greater than 50,000 gallons are not provided specific requirements in this final UST regulation for using continuous interstitial monitoring and the combination of automatic line leak detectors with interstitial monitoring for piping. Many of these systems lack secondary containment and automatic line leak detectors cannot adapt to the operating pressures of these systems. In the 2011 proposed UST regulation, EPA asked if testing the piping for airport hydrant systems and field-constructed tanks at operating pressure was sufficient. The 1988 UST regulation requires owners and operators test conventional systems at one and a half times operating pressure. EPA is aware that airport hydrant system piping operates at high pressures and agrees with commenters who stated that testing above operating pressure might be infeasible. This final UST regulation requires owners and operators to test these systems at least at operating pressure, because these large piping systems operate at pressures much higher than conventional gasoline stations. However, EPA is allowing testing at or above operating pressure, but is not providing a set value. Professional testers can decide the appropriate pressure to test these systems, as long as the pressure is at least the operating pressure of the system. Release Detection Requirements for Tanks Associated With Airport Hydrant Systems and Field-Constructed Tanks This final UST regulation establishes release detection requirements for tanks associated with airport hydrant systems and field-constructed tanks. Airport hydrant systems may consist of a series of large capacity shop fabricated tanks, although some airport hydrant systems use field-constructed tanks. Shop fabricated tanks and field-constructed tanks with a capacity less than or equal to 50,000 gallons must meet the requirements in subpart D. Fieldconstructed tanks with capacity greater than 50,000 gallons must either be monitored using release detection methods in subpart D (except for passive groundwater and vapor monitoring which must be combined with inventory control as described below) or use one of the alternative PO 00000 Frm 00030 Fmt 4701 Sfmt 4700 methods for tanks listed at § 280.252(d)(1). Feasibility of Proposed Release Detection Options for Field-Constructed Tanks To allow owners and operators more flexibility in meeting the release detection requirement, EPA proposed these four alternatives for UST systems with field-constructed tanks greater than 50,000 gallons: • Annual tank tightness test • Automatic tank gauging system that can detect a 1 gph leak combined with a tank tightness test every three years • Automatic tank gauging system that can detect a 2 gph leak combined with a tank tightness test every two years and • Other methods approved by the implementing agency EPA requested comment or additional data on the proposed release detection options to determine their feasibility. Most commenters thought the release detection options were appropriate and sufficient. One commenter thought EPA should include chemical marker or tracer testing. Another commenter thought EPA should expand the types of release detection methods specified in the final UST regulation to include use of sensors, probes, monthly visual inspections, or other methods approved by the implementing agency. EPA met with and obtained information from DoD and release detection vendors throughout the regulatory process. EPA researched suggested release detection options and standard practices conducted by DoD following the public comment period for the 2011 proposed UST regulation. EPA found that these facilities perform inventory management on their UST systems. EPA determined that although not performed as specified in the 1988 UST regulation, some DoD facilities are performing fuel management methods to monitor and track fuel inventories for their field-constructed tanks.77 78 Release Detection Options for FieldConstructed Tanks in the Final UST Regulation Based on comments and additional information from DoD as well as commercial airports about their operations, EPA is including in this final UST regulation all release 77 Final Report—Validation of the Low-Range Differential Pressure (LRDP) Leak Detection System for Small Leaks in Bulk Fuel Tanks Environmental Security Technology Certification Program, U.S. Department of Defense. 78 DoD 4140.25–M: Management of Bulk Petroleum Products, Storage, and Distribution Facilities, Volume V https://www.dtic.mil/whs/ directives/corres/html/414025m_vol1_3.html. E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations detection options discussed in the 2011 proposed UST regulation. EPA is also adding three other options to this final UST regulation. Owners and operators of field-constructed tanks less than or equal to 50,000 gallons must meet the release detection requirements in subpart D. Owners and operators of field-constructed tanks greater than 50,000 gallons must use the alternative release detection methods described in subpart K or the release detection options in subpart D (except that groundwater and vapor monitoring must be used in combination with inventory control as described below). EPA thinks these options are reasonable and will quickly detect releases when they occur. tkelley on DSK3SPTVN1PROD with RULES2 Tank Tightness Testing In the 2011 proposed UST regulation, EPA discussed the option of owners and operators performing annual tank tightness testing that can detect a 0.5 gallon per hour leak rate. EPA proposed this performance standard based on information about leaks from several field-constructed tanks. The information indicated leak rates from the tanks ranged from 0.31 gph to 10 gph, with a median leak rate of 0.58 gph. EPA determined that most available methods were capable of meeting the proposed leak rate of 0.5 gph. EPA did not receive comments regarding the performance standard during the public comment period. The final UST regulation retains the option for owners and operators to perform annual underground tank tightness testing that can detect a 0.5 gallon per hour leak rate. Automatic Tank Gauging Combinations with Tank Tightness Testing This final UST regulation allows owners and operators to combine an automatic tank gauging system with a tank tightness test that achieves different leak rates during different periods of performance. One combination uses an automatic tank gauging system performing release detection at least every 30 days that can detect a leak rate less than or equal to 1 gallon per hour with a tank tightness test that can detect a 0.2 gallon per hour leak rate performed at least every three years. Another combination couples an automatic tank gauging system performing release detection at least every 30 days that can detect a leak rate less than or equal to 2 gallons per hour with a tank tightness test that can detect a 0.2 gallon per hour leak rate performed at least every two years. This automatic tank gauging requirement is different from the release detection requirement in the 1988 UST regulation for factory built tanks. These leak rates VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 and time frames for release detection testing are appropriate because they will detect releases within a reasonable time frame, given the large tank sizes and time needed to perform testing on these tanks. Inventory Control This final UST regulation allows inventory control combined with one of these methods: passive groundwater monitoring every 30 days, passive vapor monitoring every 30 days, or a 0.5 gallon per hour tank tightness test performed at least once every two years. The inventory control option must meet the same requirements as inventory control for piping associated with airport hydrant systems and fieldconstructed tanks described in the Release Detection Options for Piping in the Final UST Regulation section above. Groundwater and Vapor Monitoring This final UST regulation allows active vapor monitoring for tanks using the same requirements as described in the Release Detection Options for Piping in the Final UST Regulation section above. In addition, owners and operators may also use a combination method incorporating inventory control and passive vapor monitoring or groundwater monitoring using the requirements described in the Release Detection Options for Piping in the Final UST Regulation section above. Other Methods for Field-Constructed Tanks Implementing agencies may approve another method if the owner and operator demonstrate the method can detect a release as effectively as any of the other five methods described in the Release Detection Options for FieldConstructed Tanks section. In comparing methods, an implementing agency shall consider the size of release the method can detect and frequency and reliability of detection. Other methods are described in Other Methods for Piping. Release Detection Recordkeeping This final UST regulation requires owners and operators maintain records of release detection for field-constructed tanks and airport hydrant systems in accordance with § 280.45. The results of any sampling, testing, or monitoring must be maintained for at least one year except as follows: Tank tightness testing; line tightness testing; and vapor monitoring using a tracer compound placed in the tank system must retain records until the next test is conducted. EPA is requiring owners and operators maintain these records until the next PO 00000 Frm 00031 Fmt 4701 Sfmt 4700 41595 test is conducted because owners and operators can choose different time frames to conduct release detection testing. This additional flexibility results in some testing occurring at frequencies ranging from less than one year to up to three years. Release Prevention As with all other regulated UST systems, this final UST regulation requires airport hydrant systems and field-constructed tanks meet corrosion protection, spill, and overfill requirements, as well as walkthrough inspections. Corrosion Protection This final UST regulation requires all airport hydrant systems and fieldconstructed tanks that routinely contain regulated substances and are in contact with the ground to meet corrosion protection requirements in § 280.252(b)(1). Metal tanks and piping which are encased or surrounded by concrete have no metal in contact with the ground and are not subject to the corrosion protection requirements. Because interim prohibition for deferred UST systems in the 1988 UST regulation has been in effect since May 1985, many of these systems are already equipped with corrosion protection (that is, constructed of: Non-corrodible material, coated and cathodically protected steel, fiberglass reinforced plastic, or steel tank clad with fiberglass reinforced plastic). In this final UST regulation, EPA renames § 280.11 to Installation requirements for partially excluded UST systems. For corrosion protection, airport hydrant systems and fieldconstructed tanks must meet the requirements in § 280.252(b)(1). Owners and operators must meet this requirement within three years of the effective date of this final UST regulation. This final UST regulation does not allow an internal lining as a method for meeting the corrosion protection upgrade requirement. EPA is not allowing an internal lining as corrosion protection because it does not protect steel in contact with the ground from corroding and causing a release to the environment. Field-constructed tanks and tanks associated with airport hydrant systems, which are not upgraded according to § 280.252(b), and are installed on or before the effective date of this final UST regulation must be permanently closed according to § 280.70. Spill and Overfill Prevention EPA concludes that using properly functioning equipment, which is E:\FR\FM\15JYR2.SGM 15JYR2 41596 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 operated according to manufacturer guidelines, is necessary to protect human health and the environment. After discussions with industry, DoD, and commercial airport personnel, EPA understands that existing airport hydrant systems are generally already equipped with spill and overfill prevention equipment to prevent spills and overfills. This final UST regulation requires owners and operators of airport hydrant systems and field-constructed tanks to have spill and overfill prevention equipment and conduct testing or inspections of the equipment. This will ensure the systems and tanks operate properly, contain releases, and decrease the likelihood of a leak into the environment. Owners and operators must install spill and overfill prevention equipment and conduct the first test or inspection within three years of the effective date of this final UST regulation, then at least once every three years thereafter. For more information on spill prevention equipment testing and overfill prevention equipment inspections, see sections B–2 and B–3, respectively. Walkthrough Inspections Owners and operators need to properly operate and maintain their UST system equipment in order to prevent and quickly detect releases. Therefore, this final UST regulation adds requirements for owners and operators of airport hydrant systems and field-constructed tanks to perform periodic walkthrough inspections to prevent and quickly detect releases. EPA found that owners and operators of airport hydrant systems are required to ensure safety and fuel quality, and frequently inspect these systems as part of other requirements and recommendations to ensure system components are operating properly. In addition, EPA understands that airport hydrant systems and some fieldconstructed tank facilities are already performing operation and maintenance inspections that ensure their systems and associated spill and overfill equipment are operating properly. Thus, EPA found these requirements will impose little, if any, additional burden at these facilities. This final UST regulation requires owners and operators of airport hydrant systems and field-constructed tanks conduct walkthrough inspections according to § 280.36. In addition, EPA is requiring owners and operators inspect hydrant pits and hydrant piping vaults. These areas are unique to airport hydrant systems. It is important to look at hydrant pits and hydrant piping vaults as part of periodic walkthrough VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 inspections to ensure these areas are: Free of liquid and debris, not damaged, and free of leaks. Owners and operators must inspect these areas at least once every 30 days if OSHA confined space entry is not required or at least annually if OSHA confined space entry is required. See 29 CFR part 1910 for information about OSHA confined space entry. Some owners and operators already periodically check these areas using the ATA guidance manual, Airport Fuel Facility Operations and Maintenance Guidance Manual. Owners and operators must conduct the first inspection within three years of the effective date of the final UST regulation. For more information on walkthrough inspections, see section B–1. Secondary Containment This final UST regulation does not require secondary containment for new and replaced piping associated with field-constructed tanks greater than 50,000 gallons in capacity or piping associated with airport hydrant systems. EPA understands this piping typically is larger diameter and runs for long distances, making it difficult to slope the piping to an interstitial monitoring area. In addition, EPA understands it is difficult to keep water out of the interstitial area of long piping runs. Since nearly all this piping is steel, corrosion can occur in the interstitial area when an electrolyte, such as water, is in the interstitial area. This corrosion can significantly shorten the piping’s operational life. Corrosion protection on the outside of the piping protects the part of the piping in contact with the ground from corrosion, but does not protect the inside part of piping from corrosion. To prevent corrosion caused by water in the interstitial area, owners and operators would need to add corrosion protection inside the interstitial area of piping, which EPA realizes would be difficult to do. Given these issues, EPA has determined that requiring secondary containment for these piping runs is not practical. However, EPA is requiring secondary containment for new and replaced piping associated with field-constructed tanks 50,000 gallons or less that do not feed airport hydrant system piping. EPA understands that new, smaller fieldconstructed tanks, such as those constructed within tanks following permanent closure of an existing UST, typically have piping similar to that installed at commercial gasoline stations. This piping can effectively meet the secondary containment requirements and better protect the PO 00000 Frm 00032 Fmt 4701 Sfmt 4700 environment. For more information, see section A–2, Secondary Containment. Notification The 1988 UST regulation did not require owners of airport hydrant systems or field-constructed tanks to comply with the notification requirements of § 280.22, which included certifying proper installation of airport hydrant systems. The 2011 proposed UST regulation required owners and operators of airport hydrant systems and field-constructed tanks installed prior to the effective date of the final UST regulation provide notification of existence to implementing agencies within 30 days of the effective date of this final UST regulation. This final UST regulation modifies the 2011 proposed UST regulation by requiring owners and operators provide a one-time notification of existence to implementing agencies no later than 3 years after the effective date of this final UST regulation. EPA agrees with commenters that airport hydrant system owners and operators need more than 30 days to provide the one-time notification of existence. This change allows owners and operators, as well as implementing agencies, time to identify airport hydrant systems covered by the final UST regulation and gives implementing agencies time to include these systems in their inventories. The final UST regulation does not consider currently installed tanks, including airport hydrant systems, as new UST systems. Therefore, EPA is requiring owners and operators only certify proper installation for airport hydrant systems and field-constructed tanks installed on or after the effective date of the final UST regulation according to § 280.22. In addition, EPA is requiring owners notify within 30 days of ownership change. See section D–3 for more information on notification requirements. Financial Responsibility Because EPA is eliminating the deferral for airport hydrant systems and field-constructed tanks, they are no longer be excluded from the financial responsibility requirements in subpart H. Owners and operators who install these UST systems after the effective date of this final UST regulation must comply with the financial responsibility requirements at installation. Owners and operators of airport hydrant systems and field-constructed tanks in use as of the effective date of this final UST regulation must have financial responsibility when they submit the one-time notification of existence for E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations these systems. However, subpart H exempts federal and state entities, which means that federal and state owners and operators of airport hydrant systems and field-constructed tanks do not have to meet the financial responsibility requirement. Operator Training EPA is aware that commercial airports are required to follow fuel facility training requirements of 14 CFR part 139; however, those requirements do not cover specifics of the UST requirements. This final UST regulation requires owners and operators of airport hydrant systems and field-constructed tanks meet the operator training requirements of subpart J. Owners and operators of some airport hydrant systems that are considered underground storage tanks may have already complied with state operator training requirements. For example, personnel from General Mitchell Field in Wisconsin report that operators have received Wisconsin class A and B operator training certification. All owners and operators must begin meeting this requirement not later than three years after the effective date of this final UST regulation. For more information see section A–1, Operator Training. tkelley on DSK3SPTVN1PROD with RULES2 Partially Excluded Components EPA regulates UST systems, including tanks and underground piping, in 40 CFR part 280 and aboveground tanks in 40 CFR part 112 (Oil Pollution Prevention). Facilities with greater than 1,320 gallons of aboveground oil storage capacity that could reasonably be expected to discharge oil into navigable waters or adjoining shorelines are subject to the SPCC regulation under the authority of the Clean Water Act.79 The SPCC regulation includes requirements for oil spill prevention, preparedness, and response to prevent oil discharges into navigable waters and adjoining shorelines. The SPCC regulation also requires regular inspections of aboveground valves, piping, and appurtenances along with integrity and leak testing of buried piping at the time of installation, modification, construction, relocation, or replacement. Facilities regulated by the SPCC regulation must also prepare and maintain a written SPCC plan that includes measures to prevent, prepare for, and respond to oil discharges that 79 https://www.ecfr.gov/cgi-bin/text-idx?c=ecfr& SID=b843807afdc641b203ffec44aa671d36&rgn= div5&view=text&node=40:23.0.1.1.7&idno=40. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 threaten navigable waters or adjoining shorelines. Aboveground storage tanks associated with airport hydrant systems and fieldconstructed tanks covered in this final UST regulation do not have to meet many of the requirements in the UST regulation because they are neither beneath the surface of the ground, nor in contact with the ground. For these reasons, the SPCC regulation is the most effective means of addressing the aboveground storage tanks associated with UST systems. Airport hydrant systems that do not meet the definition of UST system because the underground portion is less than 10 percent of the system capacity may be subject to the SPCC regulation for both the aboveground and underground portions of the system. Underground storage tank components such as hydrant pits and piping vaults are considered part of the UST system and subject to the requirements in 40 CFR part 280. Complementary Regulation of Partially Buried Tanks Partially buried (also called partially covered) field-constructed tanks may be regulated by both this final UST regulation and the SPCC regulation. The SPCC regulation exempts only completely buried storage tanks subject to all of 40 CFR part 280.80 Additionally, the SPCC regulation covers tanks situated on top of the ground’s surface or partially buried (for example, bunkered, also referred to as mounded tanks) and considers these to be aboveground storage tanks. If 10 percent or more of the total capacity of the tank or tanks and underground piping is underground, the tank system meets the definition of an UST regulated by 40 CFR part 280 or state equivalent program approved under 40 CFR part 281. Therefore, these containers or systems are covered by both SPCC and UST regulations. These regulations are complementary because the SPCC regulation focuses on oil discharges that could impact navigable waters or shorelines, while the UST regulation focuses primarily on day-to-day maintenance and operation to prevent releases that impact soil and groundwater. Change from Deferred to Partially Excluded The 2011 proposed UST regulation used the term deferred for aboveground 80 40 CFR 112.2 defines completely buried as any container completely below grade and covered with earth, sand, gravel, asphalt, or other material. Containers in vaults, bunkered tanks, or partially buried tanks are considered aboveground storage containers for purposes of the part.

The proposal indicated that although these aboveground storage tanks would be subject to some parts of the final UST regulation, EPA intended to continue evaluating whether to fully regulate them in the future. EPA reconsidered these aboveground storage tanks and is making the final determination that the SPCC requirements are the most effective means for addressing oil discharges from aboveground storage tanks. This final UST regulation excludes from subparts B, C, D, E, G, J, and K aboveground storage tanks associated with airport hydrant systems and field-constructed tanks. Aboveground storage tanks that are part of an UST system must continue to meet the requirements of subparts A and F. 3. Wastewater Treatment Tank Systems that Are Not Part of a Wastewater Treatment Facility Regulated Under Sections 402 or 307(b) of the Clean Water Act In the 2011 proposed UST regulation, EPA removed the existing deferral in § 280.10(c)(1) for wastewater treatment tank systems that are not part of a wastewater treatment facility regulated under sections 402 or 307(b) of the Clean Water Act. Since the 1988 UST regulation, owners and operators of these systems (hereafter referred to as wastewater treatment tanks) were deferred from complying with 40 CFR part 280, subparts B (UST Systems: Design, Construction, Installation and Notification); C (General Operating Requirements); D (Release Detection); E (Release Reporting, Investigation, and Confirmation); G (Out-of-Service UST Systems and Closure); and H (Financial Responsibility). Owners and operators have been required to comply with requirements for interim prohibition and release response and corrective action (40 CFR part 280, subparts A and F) since the effective date of the 1988 UST regulation. However, removing the deferral, as discussed in the 2011 proposed UST regulation, would have required owners and operators comply with all subparts of 40 CFR part 280. Change from Deferred to Partially Excluded The 1988 UST regulation used the term deferred for wastewater treatment tanks. Although these tanks were subject to some parts of the UST regulation, EPA intended to continue evaluating whether or not to regulate these tanks at a future date. EPA reconsidered these tanks and is making a final determination. EPA is excluding E:\FR\FM\15JYR2.SGM 15JYR2 41598 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 these tanks from most requirements in this final UST regulation; however, the regulatory requirements in subparts A and F for these systems remain the same. EPA deferred wastewater treatment tanks in the 1988 UST regulation due to uncertainty about the number of tanks that existed and the appropriateness of release detection for these systems. EPA’s intent in removing the deferral for these tanks in the 2011 proposed UST regulation was to regulate them further, which would protect human health and the environment from discharges of regulated substances contained in these systems. EPA used the proposal to obtain additional information on these systems, and determine if there were appropriate release prevention and detection technologies available to fully regulate them according to the UST regulation. According to commenter responses, EPA determined that these tanks are often subject to other environmental regulations; it may not be technically feasible to install release prevention and detection equipment on these systems due to varying designs of these systems; and many of these systems contain mostly water and are not significant sources of contamination. Installation Requirements for Partially Excluded Tanks In the 1988 UST regulation, deferred wastewater treatment tanks were required to meet the interim prohibition requirements at § 280.11 (that is, corrosion protected, made of noncorrodible materials, or otherwise designed and constructed to prevent releases during the operating life of the facility due to corrosion or structural failure). Therefore, these tanks are already equipped with corrosion protection if they were installed after the effective date of the 1988 UST regulation. EPA thinks it is appropriate to maintain this requirement, which ensures these tanks are provided with some degree of corrosion protection to prevent releases into the environment. Because EPA is partially excluding these systems, the term interim prohibition no longer applies. Therefore, EPA is rewording the title of § 280.11 to Installation requirements for partially excluded UST systems. In addition, EPA is changing § 280.11(a) to reflect that these requirements are installation requirements rather than prohibitions on installation. Many commenters did not support removing the deferral to regulate these UST systems and were unsure of the universe of wastewater treatment tanks. To address this concern, EPA developed VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 a February 2012 document describing wastewater treatment tanks that would have been regulated under the final UST regulation.81 Several commenters also voiced concern that regulating these systems may result in unintended consequences (for example, impracticability of technical requirements and dual regulation) for owners and operators and implementing agencies. To help determine the feasibility of the 2011 proposed UST regulation, EPA asked several stakeholders about operating various types of wastewater treatment tanks.82 83 84 EPA also gathered information from commenters about implementing other regulations that apply to these systems.85 86 87 88 After considering commenters’ feedback, EPA concluded that the historic level of regulation for these tanks is appropriate and provides adequate controls to ensure environmental protection. This final UST regulation excludes owners and operators of wastewater treatment tanks from 40 CFR part 280, subparts B (UST Systems: Design, Construction, Installation and Notification); C (General Operating Requirements); D (Release Detection); E (Release Reporting, Investigation, and Confirmation); G (Out-of-Service UST Systems and Closure); H (Financial Responsibility); J (Operator Training); and K (UST Systems with FieldConstructed Tanks and Airport Hydrant Fuel Distribution Systems). EPA is basing this decision on maintaining the installation requirement (§ 280.11), other regulatory controls in place, and the additional information gathered. Owners and operators of wastewater treatment tank systems are still required to comply with subparts A (Program Scope and Installation Requirements for Partially Excluded UST Systems); and F (Release Response and Corrective Action for UST Systems Containing Petroleum or Hazardous Substances). 81 https://www.epa.gov/oust/fedlaws/wwtts_2-2912_final.pdf. 82 April 2012 telephone conversation with Tom Groves, New England Interstate Water Pollution Control Commission. 83 April 2012 telephone conversation with Ming Pan, Massachusetts Department of Environmental Protection. 84 April 2012 telephone conversation with Joe Cerutti, Massachusetts Department of Environmental Protection. 85 March 2012 telephone conversation with Kevin Brackney, Nez Perce Tribe. 86 April 2012 telephone conversation with Chris Wiesberg, Missouri Department of Natural Resources. 87 April 2012 telephone conversation with Mary Hansen, Washington State Department of Ecology. 88 May 2012 telephone conversation with Candace Cady, Utah Department of Environmental Quality.

USTs Containing Radioactive Material and Emergency Generator UST Systems at Nuclear Power Generation Facilities Regulated by the Nuclear Regulatory Commission In the 2011 proposed UST regulation, EPA maintained the existing deferral in § 280.10(c)(2) and (3) for USTs containing radioactive material and for emergency generator UST systems at nuclear power generation facilities regulated by the United States Nuclear Regulatory Commission (NRC). Since the 1988 UST regulation, owners and operators of these tanks were deferred from complying with 40 CFR part 280, subparts B (UST Systems: Design, Construction, Installation and Notification); C (General Operating Requirements); D (Release Detection); E (Release Reporting, Investigation, and Confirmation); G (Out-of-Service UST Systems and Closure); and H (Financial Responsibility). Owners and operators have been required to comply with requirements for interim prohibition and release response and corrective action (40 CFR part 280, subparts A and F) since the effective date of the 1988 UST regulation. After review of DOE Orders and NRC regulations,89 EPA determined these requirements are comparable to EPA requirements for new and existing USTs regarding spill and overfill control (§ 280.30); operation and maintenance of corrosion protection (§ 280.31); and release detection (40 CFR part 280, subpart D).

DOE uses orders to regulate radioactive materials at their facilities. NRC regulations at 10 CFR part 50 require that construction permit applications include a design and safety analysis, health and safety risk assessment of facility operations, and determination of the adequacy of controls for accidental releases into the environment for the life of the operating unit. NRC regulations also require facilities meet minimum design, installation, testing, and performance criteria.95 Appendix B of 10 CFR part 50 requires a quality assurance report that includes testing of facility structures, systems, and components.96 NRC also developed guidance documents to assist operators with licensing compliance.97 EPA was concerned with whether NRC and DOE cleanup standards for radionuclides adequately protect 90 DOE Order 435.1 Chg 1, Radioactive Waste Management, ensures management of DOE radioactive waste (i.e. high-level, transuranic, lowlevel, and the radioactive component of mixed waste) is consistent with Atomic Energy Act of 1954 responsibilities, in a manner that provides radiological protection from DOE operations.

The 1988 UST regulation contains prescriptive procedures UST owners and operators must follow in responding to releases into the environment. NRC regulations are performance-based actions; they identify performance measures that are designed to ensure an adequate safety margin and offer incentives for licensees to improve safety without formal regulatory intervention.101 Accordingly, DOE created orders to supplement EPA regulations for USTs at DOE facilities already subject to the 1988 UST regulation.102 NRC requires that facilities perform site remediation as part of the decommissioning process, but there are currently no NRC regulations that require remediation at active facilities, unless dose limits are exceeded.103 EPA concludes it is appropriate to continue requiring release response and corrective action for these tanks, if the need arises. Due to the sensitive nature of these facilities, implementing agencies have flexibility to establish appropriate response and remediation requirements for owners and operators at these facilities. Move from Deferred to Partially Excluded The 1988 UST regulation used the term deferred for USTs containing radioactive material and for emergency generator UST systems at nuclear power generation facilities regulated by the NRC. This indicated that although these tanks were subject to some parts of the UST regulation, EPA intended to continue evaluating the applicability of full regulation of these tanks at a future date. EPA reconsidered these tanks and is making a final determination. EPA is 98 February 1997 letter from EPA to the NRC expressing concerns over the NRC’s proposal for increasing dose limits and eliminating the requirement to protect groundwater that could be used as drinking water. 99 December 1997 letter from EPA to DOE expressing concerns that DOE’s draft rule 10 CFR part 834 (Radiation Protection of the Public and the Environment) needs to be consistent with CERCLA and that inconsistencies exist between the draft rule and CERCLA and NCP guidance. 100 October 2002 Memorandum of Understanding between EPA and NRC to identify the interactions for only the decommissioning and decontamination of NRC-licensed sites and ensure dual regulation does not occur regarding the cleanup and reuse of NRC-licensed sites. 101 Contract No. GS–10F–0309N, EPA Work Order No. EP–G10S–00001, Work Order No. 1004, Task 2, Subtask c, Quick Turnaround Request No. 6, Release Response and Corrective Action. 102 Ibid. 103 Ibid.

Installation Requirements for Partially Excluded Tanks In the 1988 UST regulation, deferred USTs containing radioactive material and emergency generator UST systems at nuclear power generation facilities regulated by NRC were required to meet the interim prohibition requirements of § 280.11 (that is, corrosion protected, made of non-corrodible materials, or otherwise designed and constructed to prevent releases during the operating life of the facility due to corrosion or structural failure). While NRC’s regulation addresses design and installation standards, interim prohibition requirements have been in effect since the 1988 UST regulation. Accordingly, owners and operators have had to follow this requirement since the effective date of the 1988 UST regulation. EPA has no information suggesting that maintaining this requirement has been an issue for owners and operators. After considering commenters’ feedback, EPA concluded that the historic level of regulation for these tanks is appropriate and provides adequate environmental controls to ensure environmental protection. Therefore, this final UST regulation continues to require that owners and operators of these tanks comply with the requirements of § 280.11. Because EPA is partially excluding these systems, the term interim prohibition no longer applies. Therefore, EPA is rewording the title of § 280.11 to Installation requirements for partially excluded UST systems. In addition, EPA is changing § 280.11(a) to reflect that these requirements are installation requirements rather than prohibitions on installation. After considering comments and additional information, this final UST regulation excludes owners and operators of these tanks from 40 CFR part 280, subparts B (UST Systems: Design, Construction, Installation and Notification); C (General Operating Requirements); D (Release Detection); E (Release Reporting, Investigation, and Confirmation); G (Out-of-Service UST Systems and Closure); H (Financial Responsibility); J (Operator Training); and K (UST Systems with FieldConstructed Tanks and Airport Hydrant Fuel Distribution Systems). Owners and operators of these tank systems are still required to comply with subparts A (Program Scope and Installation Requirements for Partially Excluded E:\FR\FM\15JYR2.SGM 15JYR2 41600 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations UST Systems) and F (Release Response and Corrective Action for UST Systems Containing Petroleum or Hazardous Substances). This final UST regulation also amends § 280.10(c)(4) which refers to facilities licensed under 10 CFR part 50. This change is consistent with the regulatory citation listed in the Spill Prevention, Control, and Countermeasure provision in 40 CFR part 112 and also applies to installation of these tanks at NRC facilities in the future. D. Other Changes tkelley on DSK3SPTVN1PROD with RULES2 1. Changes to Overfill Prevention Equipment Requirements Through extensive stakeholder outreach, EPA identified vent line flow restrictors (also called ball float valves) as a significant concern for operability and safety. As a result, this final UST regulation modifies the 1988 UST regulation by eliminating vent line flow restrictors as an option for meeting the overfill prevention equipment requirement for new tank installations and when overfill prevention equipment is replaced. EPA makes this change to: reduce the frequency of UST releases due to operability issues, address system safety concerns, and address personnel safety concerns. Below are the issues: • Operability—For a vent line flow restrictor to operate properly, the device must restrict the flow of regulated substance into the UST when the flow restrictor engages. If the tank top is not liquid or vapor tight, flow into the UST is not restricted because vapors continue to escape through non-tight areas. If vapors continue to escape from the UST, there is no pressure buildup in the vapor area of the tank, resulting in no reduced flow rate into the UST. Examples where non-tight tank tops may result in ineffective flow restrictors include: loose tank bungs or other tank top components; tanks with coaxial stage I vapor recovery installed; and tanks with both tank top and remote fill areas. • System safety—Vent line flow restrictors can create safety concerns when they activate. USTs can become over pressurized and be damaged during deliveries when product is pumped into the tank. PEI’s recommended practice for installation, RP 100, advises against using vent restriction devices because the vent line flow restrictor pressurizes the UST, creating a hazardous condition when the device operates as designed. • Personnel safety—Delivery personnel can be sprayed with regulated substances when they disconnect the delivery hose from the fill pipe because VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 pressure can build up in the tank when the vent line flow restrictor activates. Owners and operators may continue to use flow restrictors not in vent lines (such as flow restrictors in fill pipes), automatic shutoff devices, and high level alarms to meet the overfill prevention requirement for their UST systems. Owners and operators using a vent line flow restrictor before the effective date of this final UST regulation may continue using it to meet the overfill prevention requirement, as long as it operates properly by restricting the flow of regulated substances into the UST when the device activates. Flow restrictors in vent lines must be periodically inspected for proper operation according to section B–3, Overfill Prevention Equipment Inspections. This means that the flow restrictor will need to be accessible to the person inspecting the overfill prevention device. In addition, owners and operators may continue to use flow restrictors in UST system vent lines for reasons other than meeting the overfill prevention requirement, as long as the flow restrictors do not interfere with operation of the overfill prevention equipment being used. Most commenters supported this change to the 1988 UST regulation. Several even suggested requiring retrofits of vent line flow restrictors with another type of overfill prevention equipment. Because EPA is concerned about imposing too many additional costs on owners and operators of existing UST systems, EPA is not requiring retrofits of existing vent line flow restriction devices, as long as they operate properly, alert delivery personnel, and prevent overfills. Some commenters suggested EPA continue to allow the use of vent line flow restrictors if they meet the criteria set forth in PEI’s RP 100. EPA reviewed the PEI recommended practice and noted that the code sets criteria for the allowed use of vent line flow restrictors. However, more importantly, the code advises against using vent line flow restrictors for overfill prevention under any circumstance because they pressurize the UST, creating a hazardous condition when the device operates as designed. Consistent with PEI’s RP 100 advisory, EPA is not allowing owners and operators to use vent line flow restrictors in new tanks or when overfill prevention equipment is replaced. Finally, several commenters suggested EPA continue to allow the use of vent line flow restrictors, as long as the flow restrictor can be shown to operate effectively. Because it is difficult to determine if flow restrictors PO 00000 Frm 00036 Fmt 4701 Sfmt 4700 in vent lines will effectively restrict flow when the tank is close to being full, EPA is not allowing their use in new UST system installations or when overfill prevention equipment is replaced. However, the final UST regulation allows continued use of vent line flow restrictors installed before the effective date of the final UST regulation, as long as they operate properly, alert delivery personnel, and prevent overfills. 2. Internal Linings that Fail the Periodic Lining Inspection and Cannot Be Repaired About 3 percent of tanks rely on internal lining as the sole method of corrosion protection to meet the 1988 UST regulation.104 Tanks that were internally lined to meet the 1988 UST regulation corrosion protection requirement at § 280.21 are typically older, bare steel tanks installed before 1986. The 1988 UST regulation preamble says that internal lining, when used as the sole method for corrosion protection, is not regarded as a permanent upgrade. However, it is adequate if the lining continues to meet original design specifications. If the internal lining no longer meets original design specifications and cannot be repaired according to industry codes, then the lined tank is subject to unprotected tank requirements and must be replaced after 1998. However, this language, which was in the 1988 UST regulation preamble, was inadvertently omitted from the 1988 UST regulation. This final UST regulation modifies the 1988 UST regulation by requiring owners and operators to permanently close an UST that uses internal lining as the sole method of corrosion protection for the tank when the lining inspection determines the internal lining is no longer performing according to original design specifications and the internal lining cannot be repaired according to a code of practice developed by a nationally recognized association or independent testing laboratory. EPA understands that codes of practice for internal lining inspections in use as of publication of this final UST regulation contain pass or fail criteria for the internal lining and criteria for allowing repairs to an internal lining that fails the internal lining inspection. 104 E2, Incorporated, memoranda and analyses submitted under Contract EP–W–05–018, U.S. Environmental Protection Agency.

Consistent with current EPA policy,105 tanks using the combination of cathodic protection and internal lining for corrosion protection are not required to be closed if the internal lining fails and cannot be repaired, as long as the cathodic protection is operated and maintained according to § 280.31 and the tank was assessed and found to be structurally sound and free of corrosion holes when the cathodic protection was added to the tank. In addition, owners and operators may use internal linings for purposes other than meeting EPA’s corrosion protection upgrade requirement (for example, internal linings used for compatibility or secondary containment). Most commenters supported this change to the 1988 UST regulation. Some even suggested more restrictive requirements: either phasing out internal lining as a corrosion protection upgrade or permanently closing an UST if the lining inspection failed. EPA is not requiring these more restrictive approaches because we think internal lining repairs can be appropriate and protect the environment when conducted according to a code of practice developed by a nationally recognized association or independent testing laboratory. In addition, requiring permanent closure under these more restrictive circumstances would place additional financial burdens on UST owners and operators. Several commenters offered adding cathodic protection and relining the tank as alternatives to permanent closure. EPA is not including these options in this final UST regulation because internally lined tanks that fail the lining inspection and cannot be repaired according to a code of practice are generally older and are nearing or past the end of their useful lives. 3. Notification This final UST regulation adds a onetime notification of existence for UST systems with field-constructed tanks and UST systems identified as airport 105 EPA UST Technical Compendium Question And Answer # 14: www.epa.gov/oust/compend/ nus.htm. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 hydrant fuel distribution systems. In addition, it adds a new notification requirement for ownership changes; provides a new form for making notification of ownership changes; and makes minor changes to the notification language and notification form. EPA agrees with commenters who opposed requiring one-time notification of existence for emergency power generator UST systems as was proposed. Commenters explained, and EPA agrees, that since the 1988 UST regulation deferred these systems only from the release detection requirements in subpart D, owners should have notified the appropriate implementing agency within 30 days of bringing an UST system into use in accordance with the notification requirements in subpart B. Therefore, in this final UST regulation, the requirement to submit a one-time notification of existence applies only to owners of UST systems with fieldconstructed tanks and airport hydrant fuel distribution systems. (This one-time notification of existence does not apply to wastewater treatment tank systems, UST systems containing radioactive material that are regulated under the Atomic Energy Act of 1954, and UST systems that are part of an emergency generator system at nuclear power generation facilities regulated by the Nuclear Regulatory Commission under 10 CFR part 50 previously deferred in the 1988 UST regulation and partially excluded in this final UST regulation.) Furthermore, EPA agrees with commenters’ requests to extend the time frame of 30 days in the 2011 proposed UST regulation for owners of UST systems with field-constructed tanks and airport hydrant fuel distribution systems to submit their one-time notification of existence. To provide owners more time for identifying and gathering information about these previously deferred systems, EPA is allowing owners of existing UST systems with field-constructed tanks and airport hydrant fuel distribution systems to submit a one-time notification of existence within 3 years of the effective date of this final UST regulation. EPA is requiring owners of UST systems with field-constructed tanks and airport hydrant fuel distribution systems brought into use after the effective date of the final UST regulation to submit notification forms; this notification requirement has been in place since 1986 for all UST owners bringing new USTs into use. See subpart K for other requirements related to UST systems with field-constructed tanks and airport hydrant fuel distribution systems. PO 00000 Frm 00037 Fmt 4701 Sfmt 4700 41601 Several commenters requested EPA allow 60 days instead of 30 days to submit a notification of ownership change, noting that the 30-day requirement is too stringent. One commenter stated that the time frame should be relaxed to account for large organizations where paperwork could involve a significant amount of time to process. Another stated that 30 days would be too short and unduly burdensome on small businesses. While EPA fully considered these comments, EPA thinks it is important for the ownership change notification requirement to be consistent with the new tank notification requirement (within 30 days of bringing an UST into use) in place since 1988. In addition, the ownership change notification form is shorter and takes less time to complete than the new tank notification form. As a result, this final UST regulation requires owners to submit a notification of ownership change within 30 days of assuming ownership of regulated UST systems. In this final UST regulation, EPA provides a new notification form titled Notification of Ownership Change for Underground Storage Tanks under appendix II. This form supplants the List of Agencies Designated to Receive Notifications in appendix II of the 1988 UST regulation. The list, published in 1988, contained agency names, addresses, and phone numbers, many of which are no longer accurate. EPA considered updating the list, but given the frequency with which contact information changes, decided it is pointless to publish information in the final UST regulation since it will quickly become obsolete. Rather, owners can obtain current agency contact information on EPA’s Web site at www.epa.gov/oust. Two commenters indicated it was unclear who the implementing agency is and whether owners and operators need to notify both the state and EPA. In this final UST regulation, EPA is clarifying that owners must submit notification forms to the appropriate implementing agency. The term implementing agency is defined in the UST regulation and owners can obtain current contact and other information regarding their implementing agency on EPA’s Web site at www.epa.gov/oust. In practice, EPA expects most owners will submit notification forms only to their respective state as their implementing agency, except in instances where the implementing agency is EPA. For example, EPA is the implementing agency for USTs located in Indian country; thus, owners with USTs in Indian country will submit their E:\FR\FM\15JYR2.SGM 15JYR2 41602 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations notification forms to EPA. Owners should also be aware that individual states may have state versions of notification forms which owners should use instead when submitting to the implementing agency. EPA is revising the regulatory language in § 280.22(a) and (b) and including language in subpart K to reflect that state forms may be used if the state requires owners to use notification forms that differ from those in appendices I and II. Lastly, EPA is amending the notification form in appendix I and the ownership change form in appendix II to incorporate comments regarding specific items on these forms. For example, two commenters noted that owners of previously deferred UST systems would be unable to complete the Certification of Installation section of the Notification for Underground Storage Tanks form because they were not subject to this requirement when the UST system was brought into use. In addition, records of installation for these previously deferred UST systems are likely to be nonexistent given the passage of time since installation. EPA agrees with these commenters and is revising the notification form to indicate that only owners of UST systems with field-constructed tanks and airport hydrant fuel distribution systems brought into use after the effective date of this final UST regulation need to complete this section. tkelley on DSK3SPTVN1PROD with RULES2 4. Compatibility Regulated Substance and Motor Fuel Definitions This final UST regulation revises the regulated substance definition to clarify that UST systems containing petroleum derived from non-crude oil products are regulated. The preamble to the supplement of the proposed 1988 UST regulation indicates that petroleum products can be derived from other materials, such as biomass, plant material, organic waste, coal, and shale oil.106 Petroleum is comprised of a complex blend of hydrocarbons regardless of its source material. Many people applied the definition of regulated substance in the 1988 UST regulation to petroleum UST systems only if the petroleum was derived from crude oil. This final UST regulation clarifies that petroleum derived from non-crude oil based products, such as green gasoline, is a regulated substance under 40 CFR part 280. This clarification is consistent with the preamble to the 1988 UST regulation, 106 ‘‘40 CFR parts 280 and 281 USTs; Supplement to Proposed Rule,’’ 52 FR 48640 (December 23, 1987). VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 which indicates petroleum is not limited to being derived from crude oil. This final UST regulation also modifies the definition of motor fuel to better accommodate new motor fuels that may be marketed and stored in the future. The definition in the 1988 UST regulation listed motor fuel products. This led to confusion as to whether new fuels, such as petroleum blended with ethanol or biodiesel, are motor fuels. This final UST regulation clarifies the definition of motor fuel and explains that it is any fuel typically used to operate a motor engine. In addition, EPA received comments to change the motor fuel definition from petroleum and petroleum-based substances to a complex blend of hydrocarbons. EPA agrees that using the phrase complex blend of hydrocarbons eliminates ambiguity; it provides a clearer definition of motor fuel by including complex blends of hydrocarbons that may not be petroleum or petroleumbased. EPA is making this change in this final UST regulation. Compatibility EPA understands that the chemical and physical properties of ethanol and biodiesel can be more degrading to certain UST system materials than petroleum alone. As the use of ethanoland biodiesel-blended fuels increases, EPA is concerned that not all UST system equipment or components are compatible with these fuel blends. For purposes of compatibility, EPA uses the term equipment to mean a group of components assembled together by the manufacturer. Compatibility can be determined for all components of a piece of equipment. Compatibility determinations for equipment are typically useful when an UST system is newly installed or when a complete piece of equipment is replaced. Examples of equipment include the piping system, STP assembly, and automatic shutoff device assembly. A component is considered an individual piece of an UST system and is typically a single piece of the equipment. Component compatibility is determined on a piece by piece basis. A component compatibility determination is typically needed when performing repairs on an UST system where only parts of a piece of equipment are replaced. Examples of components include gaskets, seals, and other individual pieces that form a piece of equipment. Gasoline containing 10 percent or less ethanol (E10) has been used in parts of the United States for many years. UST equipment and component manufacturers accommodated the E10 market by producing compatible PO 00000 Frm 00038 Fmt 4701 Sfmt 4700 equipment and components. According to the Renewable Fuels Association, ethanol is blended into over 90 percent of all gasoline sold in the United States,107 predominantly as E10. Recently, the United States has been moving toward use of higher blends of ethanol, due in part to federal and state laws encouraging increased use of biofuels. While most UST system equipment and components are compatible with E10, fuel blends containing greater than 10 percent ethanol do not have a long history of storage and may not be compatible with certain materials in existing UST systems. According to a 2011 report published by the U.S. Department of Energy’s Oak Ridge National Laboratory,108 some elastomeric materials are particularly affected by intermediate ethanol blends and certain sealants may not be suitable for any ethanol-blended fuels. A 2007 report from Underwriters Laboratories (UL) 109 evaluated the effect of 85 percent ethanol and 25 percent ethanol blends on dispenser components. Results indicated some materials used in the manufacture of seals degraded more when exposed to 25 percent ethanol test fluid than when exposed to 85 percent ethanol test fluid. Other literature suggests ethanol fuel blends can be more aggressive toward certain materials than independent fuel constituents, with maximum polymer swelling observed at approximately 15 percent ethanol by volume.110 Based on this information, this final UST regulation clarifies the compatibility requirements for owners and operators storing regulated substances containing greater than 10 percent ethanol. This final UST regulation also clarifies the compatibility requirements for owners and operators storing regulated substances containing greater than 20 percent biodiesel. Although the total use of biodiesel is significantly less than that of ethanol, biodiesel has 107 Renewable Fuels Association, Building Bridges to a More Sustainable Future: 2011 Ethanol Industry Outlook. https://www.ethanolrfa.org/page//2011%20RFA%20Ethanol%20Industry%20 Outlook.pdf?nocdn=1. 108 Oak Ridge National Laboratory, Intermediate Ethanol Blends Infrastructure Materials Compatibility Study: Elastomers, Metals, and Sealants (March 2011). 109 Underwriters Laboratories, Inc., Underwriters Laboratories Research Program on Material Compatibility and Test Protocols for E85 Dispensing Equipment (December 2007).

For example, pure biodiesel (B100) has known compatibility issues with certain materials. According to the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) Biodiesel Handling and Use Guide, Fourth Edition,111 ‘‘B100 will degrade, soften, or seep through some hoses, gaskets, seals, elastomers, glues, and plastics with prolonged exposure. . . . Nitrile rubber compounds, polypropylene, polyvinyl, and Tygon® materials are particularly vulnerable to B100.’’ In contrast, the properties of very low blends of biodiesel, such as B5 or less, are so similar to those of petroleum diesel that the American Society for Testing and Materials (ASTM) International considers conventional diesel that contains up to 5 percent biodiesel to meet its Standard Specification for Diesel Fuel Oils.112 For biodiesel blends between 5 and 100 percent, there is very little compatibility information; however, NREL’s handling and use guide concludes that biodiesel blends of B20 or less have less of an effect on materials and very low blends of biodiesel, such as B5 and B2, ‘‘. . . have no noticeable effect on materials compatibility.’’ 113 In addition, fleet service sites have stored B20 in UST systems for years, and EPA is not aware of compatibility-related releases associated with those UST systems storing B20. Therefore, this final UST regulation requires tank owners and operators who store greater than 20 percent biodiesel in their UST systems demonstrate compatibility of UST equipment or components by one of the options listed in § 280.32. This final UST regulation retains the requirement for owners and operators to use UST systems made of or lined with materials that are compatible with the substance stored in the UST system. It does not change the compatibility requirement in the 1988 UST regulation, but does add several options for owners and operators to demonstrate that their UST systems are compatible with regulated substances containing greater than 10 percent ethanol, greater than 20 111 National Renewable Energy Laboratory, Biodiesel Handling and Use Guide, Fourth Edition, (2009).

Owners and operators of these UST systems must meet one of the following options: • Use equipment or components that are certified or listed by a nationally recognized, independent testing laboratory for use with the fuel stored • Use equipment or components approved by the manufacturer to be compatible with the fuel stored In addition, owners and operators may use another option determined by the implementing agency to be no less protective of human health and the environment than the methods listed above. These options provide owners and operators flexibility in demonstrating compatibility while still protecting human health and the environment. In the past, owners and operators typically demonstrated compatibility by using equipment or components certified or listed by a nationally recognized, independent testing laboratory, such as UL. Many pieces of UST equipment and components in the ground today were manufactured before regulated substances containing ethanol or biodiesel existed and are not approved by nationally recognized, independent testing laboratories for use with these fuel blends. Currently, certain tanks and piping have been tested and are listed by UL for use with higher-level ethanol blends. However, many other pieces of equipment and components of UST systems, such as leak detection devices, sealants, and containment sumps, may not be listed by UL or another nationally recognized, independent testing laboratory for use with these blends. In addition, EPA is not aware of any nationally recognized, independent testing laboratory that has performed compatibility testing on UST system equipment or components with biodiesel-blended fuels. Absent certification or listing from a nationally recognized, independent testing laboratory or other verification that the equipment or component may be used with anything other than conventional fuels, the suitability of an UST system for use with biodiesel blends is questionable. As a result, EPA is providing several options for demonstrating compatibility to reduce the risk of releases due to material incompatibility. Owners and operators storing regulated substances blended with greater than 10 percent ethanol or greater than 20 percent biodiesel must meet the compatibility requirements before storing those regulated substances. PO 00000 Frm 00039 Fmt 4701 Sfmt 4700 41603 For equipment and components tested and approved by a nationally recognized, independent testing laboratory, owners and operators may demonstrate compatibility solely by keeping records of the equipment and components. In this instance, the testing laboratory’s listing, labeling, or approval demonstrates the equipment or component’s suitability to be used with the regulated substance stored. This means owners and operators will be able to demonstrate compatibility by retaining equipment or component records. Owners and operators may also demonstrate compatibility by obtaining manufacturer’s approval of the equipment or component. The manufacturer’s approval must be in writing and include an affirmative statement that the equipment or component is compatible with the fuel blend stored. The manufacturer’s approval must also specify the range of fuel blends for which the equipment or component is compatible. The manufacturer’s approval must be issued from the equipment or component manufacturer, not another entity, such as the installer or distributor. A manufacturer’s approval enables owners and operators to demonstrate compatibility for equipment or components not approved for use by a nationally recognized, independent testing laboratory. It also provides implementing agencies with verification that the equipment or component is compatible with the fuel stored. Implementing agencies may approve other options for complying with the compatibility requirement for regulated substances containing greater than 10 percent ethanol or greater than 20 percent biodiesel if they are no less protective of human health and the environment than manufacturer’s approval or a listing, labeling, or approval by a nationally recognized, independent testing laboratory. This provides implementing agencies with flexibility to consider other approaches they determine to be appropriate. For example, in lieu of an affirmative compatibility determination, implementing agencies may allow secondarily contained UST systems using interstitial monitoring to store regulated substances containing greater than 10 percent ethanol or 20 percent biodiesel. The rationale is that a leak from the primary containment will be contained by secondary containment and detected by interstitial monitoring equipment before regulated substances reach the environment. Although these options for demonstrating compatibility apply to E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 41604 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations UST systems storing regulated substances containing greater than 10 percent ethanol and greater than 20 percent biodiesel, this final UST regulation extends the compatibility demonstration requirement to other regulated substances identified by implementing agencies. This provides implementing agencies with the flexibility to require a demonstration of compatibility if there are concerns about other existing regulated substances and when new regulated substances, such as biobutanol, enter the fuel market. EPA received comments about the difficulty in determining whether some UST system equipment or components currently installed in the ground are compatible with ethanol and biodiesel blended fuels. In fact, EPA thinks there are many cases where some equipment or components of UST systems in the ground as of 2014 are not compatible with newer fuels. Unless owners and operators specifically requested all of the UST system be compatible with higher ethanol or biodiesel blends, installers probably installed lower cost options for certain UST system equipment, such as a STP assembly, which may not be compatible with some newer fuels. Non-compatible equipment or components, such as equipment in containment sumps, are usually easier to upgrade or replace than the tank or piping because they are typically located in areas not requiring excavation. In addition, EPA provides various options for meeting the compatibility requirement. To protect the environment from releases of ethanol blends greater than 10 percent, biodiesel blends greater than 20 percent, or any other regulated substance identified by the implementing agency, owners and operators must do one of the following: • Demonstrate the UST system is compatible through certification or listing by a nationally recognized, independent testing laboratory or manufacturer approval • Replace equipment or components not compatible or for which compatibility cannot be determined • Use another option determined by an implementing agency to be no less protective of human health and the environment • Not store these regulated substances in the UST system These options provide owners and operators with adequate flexibility when demonstrating compatibility and determining whether certain regulated substances may be stored in the UST system. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 Some commenters suggested adding other options owners and operators could use for determining compatibility. One suggested addition was certification by a professional engineer (P.E.), who would perform an on-site UST system analysis to determine compatibility. In order to perform this analysis, a P.E. would need to know the manufacturer and model of all UST system equipment or components. Because this information cannot be entirely obtained through visual observation, a P.E. would need to obtain records of the equipment to make an assessment and then search for relevant equipment listings or manufacturer certifications. This means a P.E. certification is equivalent to the options in this final UST regulation. EPA does not object to a P.E. performing a records review; however, we think it is impractical for a P.E. to perform a visual assessment of an UST system and make a compatibility determination in the absence of equipment records and certifications. Therefore, EPA is not explicitly allowing a P.E. to make a compatibility determination in the absence of UST system information and compatibility certifications. Some commenters suggested EPA use a tiered approach to demonstrate compatibility for UST systems storing regulated substances containing greater than 10 percent ethanol and greater than 20 percent biodiesel, and choose one method of determining compatibility. EPA interprets tiered approach to mean requiring the more stringent option first, which is listing by a nationally recognized, independent testing laboratory. If the more stringent option is not available, the second tier would allow manufacturer’s approval. This final UST regulation does not include a tiered approach because EPA thinks using this method for demonstrating compatibility makes the final UST regulation too complicated for implementing agencies as well as owners and operators. Even if the UST system equipment or components have a listing from a nationally recognized, independent testing laboratory, we do not always know whether compatibility testing was part of the listing. EPA thinks manufacturers will only issue written claims of compatibility if they have sufficient information to support such claims. The 2011 proposed UST regulation required owners and operators retain these records: • For all new and replaced equipment or components—so it is easier to demonstrate whether or not the equipment or component is PO 00000 Frm 00040 Fmt 4701 Sfmt 4700 compatible with the regulated substance stored • For UST systems storing greater than 10 percent ethanol, greater than 20 percent biodiesel, or other regulated substance identified by the implementing agency—to demonstrate the UST system is compatible with these regulated substances or compliance with alternatives allowed by the implementing agency However, after careful consideration of comments, this final UST regulation does not require owners and operators maintain records for all new and replaced equipment. EPA decided it is too onerous for owners and operators to maintain this information, which may not transfer when facilities change ownership. To make it easier for UST owners and operators to comply with the compatibility requirement, this final UST regulation requires that owners and operators notify the implementing agency at least 30 days before switching to a regulated substance containing greater than 10 percent ethanol, greater than 20 percent biodiesel, or any other regulated substance identified by the implementing agency. This notification prior to switching fuels gives the implementing agency an opportunity to inquire about the compatibility of the UST system before owners and operators begin storing the new regulated substance. This notification requirement already exists in some states. For example, Colorado, North Carolina, and South Carolina require UST owners submit a completed compatibility checklist prior to storing some newer fuel blends. To notify, owners and operators may contact implementing agencies via EPA’s Web site at www.epa.gov/oust/. This final UST regulation requires owners and operators maintain records that demonstrate compliance with § 280.32(b) for as long as the UST system stores greater than 10 percent ethanol, greater than 20 percent biodiesel, or other regulated substances identified by the implementing agency. Owners and operators must retain records for these regulated substances in order to meet this compatibility requirement. The 2011 proposed UST regulation preamble included an extensive list of UST system equipment and components that must be compatible but that list was not in the 2011 proposed UST regulation. Based on commenter input, this final UST regulation includes a list of UST system equipment and components that owners and operators E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations must demonstrate to be compatible when using the manufacturer’s approval and certification or listing options. The UST system equipment or components that owners and operators must demonstrate to be compatible are those related to the tank, piping, containment sumps, pumping equipment, release detection equipment, spill prevention equipment, and overfill prevention equipment. These items are a subset of an UST system, as defined by § 280.12, which, if incompatible, could lead to a release. This changes protect human health and the environment from potential releases from incompatible UST systems. These changes are not overly burdensome, nor do they require costly retrofits. They give owners and operators flexibility, yet provide EPA with confidence that UST systems are compatible with new fuel blends when owners and operators use one or more of the options to determine compatibility. This final UST regulation provides owners and operators with certainty about which options are allowed for demonstrating UST system compatibility with the substances stored. Finally, EPA is removing from the compatibility section of the 1988 UST regulation API Recommended Practice 1627, which is a code of practice related to methanol-blended fuels. EPA included this code of practice in the 1988 UST regulation to help owners and operators demonstrate compliance with the compatibility requirement for methanol-blended fuels. However, EPA’s subsequent review of this code revealed no substantial information about determining compatibility of UST systems with methanol-blended fuels. In August 2010, API published an updated version of API Recommended Practice 1626, which is a code of practice for storing and handling of ethanol-blended fuels. In the 2011 proposed UST regulation, EPA removed this code of practice because the proposed UST regulation provided specific requirements about how owners and operators may demonstrate compatibility for their UST systems. However, because commenters pointed out the code of practice includes requirements for demonstrating compatibility of UST systems with ethanol-blended fuels, EPA is including it as a code of practice that may be useful in complying with the compatibility section in this final UST regulation. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 5. Improving Repairs Changes to the Definition of Repair This final UST regulation adds these UST system components to the definition of repair: piping; spill prevention equipment; overfill prevention equipment; corrosion protection equipment; and release detection equipment. The 1988 UST regulation definition of repair used the generic term UST system component and provided no detail about what an UST system component is. By adding these UST system components, EPA is making it clear that these specific components are subject to the repairs allowed section of the final UST regulation. This means owners and operators performing repairs on these UST system components must follow the repairs allowed section (§ 280.33). Owners and operators commonly fix UST components that have not caused a release of regulated substance from the UST system. However, the repair definition in the 1988 UST regulation did not consider these types of fixes as repairs since they were not associated with releases. This final UST regulation removes the link that a repair is only associated with a release, requiring owners and operators meet the repairs allowed section (§ 280.33) when fixing UST system components that have failed to function properly, even if they have not caused a release of product from the UST system. This change means owners and operators must perform repairs in accordance with a code of practice developed by a nationally recognized association or independent testing laboratory and test or inspect the repaired equipment. This change ensures repair activities separate from a release are conducted properly. For example, under the 1988 UST regulation, fixing a cathodic protection system was not considered a repair. In this final UST regulation, this activity is considered a repair that must meet the repair requirements in § 280.33. EPA proposed adding a suspected release as part of the definition of repair, so repairs associated with suspected releases are covered under the repair definition. However, based on comments received, EPA is not including suspected release as part of the definition of repair in this final UST regulation because that circumstance is already covered under the ‘‘failed to function properly’’ language in the repair definition. EPA disagrees with commenters suggesting EPA remove the ‘‘failed to function properly’’ language because EPA thinks repairs need to occur both when a release occurs and PO 00000 Frm 00041 Fmt 4701 Sfmt 4700 41605 when UST system equipment fails to function properly. Finally, based on comments received, EPA is adding clarifying language to the repair definition to ensure UST system component repairs restore components to proper operating condition. Tests or Inspections After Repairs This final UST regulation adds new testing or inspection requirements for spill, overfill, and secondary containment equipment following a repair and allows owners and operators up to 30 days following the repair to test or inspect the repaired UST component. EPA acknowledges that some secondary containment can be tested through normal release detection if vacuum, pressure, or liquid-filled methods of interstitial monitoring are used as the method of release detection. In these cases, the secondary containment test occurs automatically, making it unnecessary to perform additional testing. EPA agrees with commenters about using the term inspecting rather than testing as it relates to the operability of overfill prevention equipment. Performing inspections will avoid potentially overfilling the tank while ensuring the overfill prevention equipment operates properly. EPA is revising the overfill prevention equipment test to be an overfill prevention equipment inspection. EPA agrees with commenters who indicated that testing or inspection following repair should only apply to the component or components repaired and not to the entire UST system. This final UST regulation requires testing or inspection, as appropriate, following a repair only for those UST system components repaired and not to all components at the UST site. In addition, EPA is requiring owners conduct a test of the secondary containment area (including containment sumps) only if the secondary containment area is repaired and that area is used for interstitial monitoring. Note that all secondary containment areas must use interstitial monitoring for tanks and piping installed 180 days after the effective date of this final UST regulation (see section A–2, Secondary Containment for additional information). Repairs to the primary containment areas of a tank or piping may be tested using other options for tanks and piping listed in the repairs section. Several commenters expressed concern that replacing UST system components that have not yet failed to function properly would trigger the repair requirements. If owners and E:\FR\FM\15JYR2.SGM 15JYR2 41606 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 operators choose to replace UST system components, those components must meet the installation requirements in § 280.20(d). Therefore, replaced UST system components do not have to meet the repair requirements in § 280.33. EPA solicited comments about whether to consider requiring tests or inspections of spill, overfill, and secondary containment areas before returning the UST system to service, rather than within 30 days of the repair. Many commenters were supportive of requiring testing or inspection before bringing the UST system back into service. However, this final UST regulation allows owners and operators up to 30 days following the repair to conduct testing or inspections. EPA thinks owners and operators need to test or inspect the repaired component as soon as possible following the repair. However, EPA understands there are circumstances where testing or inspection before returning the UST system to service may be impractical (for example, weather conditions, remote locations, or the need to schedule a test). In these examples, the UST system would remain out of service until the test or inspection is completed, resulting in unnecessary UST system down time for owners and operators. Thirty days allows some flexibility for completing the test or inspection, while allowing the UST system to return to service. 6. Vapor Monitoring and Groundwater Monitoring This final UST regulation retains vapor monitoring and groundwater monitoring as methods of release detection for tanks and piping installed before the effective date of this final regulation, as long as owners and operators demonstrate proper installation and performance through a site assessment. In addition, this final UST regulation revises the recordkeeping requirement in § 280.45, which means owners and operators must maintain site assessments according to § 280.43(e)(6) and (f)(7) for as long as these release detection methods are used. In the 2011 proposed UST regulation, EPA phased out vapor monitoring and groundwater monitoring over a five year time frame. However, EPA received significant comments in support of retaining these release detection methods. Many commenters presented circumstances where EPA should allow owners and operators to use vapor monitoring and groundwater monitoring such as: Until the system is replaced and the secondary containment requirement is triggered; or when the VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 UST implementing agency already has or will establish additional criteria for use. In addition, commenters suggested EPA continue allowing certain UST systems to use vapor monitoring and groundwater monitoring, specifying emergency generator tanks, certain highthroughput UST systems, or specific low-throughput systems. EPA also received numerous requests to expand our proposed release detection options for airport hydrant fuel systems and field-constructed tanks to allow the use of vapor monitoring or groundwater monitoring. Under the 2011 proposed UST regulation, these options are not acceptable release detection options for owners and operators of airport hydrant systems and field-constructed tanks. EPA agrees with commenters that owners and operators of emergency generator tanks, certain high-throughput UST systems, and specific lowthroughput systems could benefit from continued use of vapor monitoring and groundwater monitoring until owners and operators replace their UST systems to meet the secondary containment requirement necessitating interstitial monitoring. EPA thinks that requiring owners and operators to maintain the site assessment will increase environmental protection appreciably beyond the 1988 UST requirements. Implementing agencies have noted that site assessments often do not exist for vapor or groundwater monitoring. Thus, by requiring site assessment records, we will ensure vapor and groundwater monitoring wells are properly located and function as effective release detection. EPA also thinks that allowing these release detection options to be customized and used for airport hydrant systems and field-constructed tanks will make it easier for owners and operators to comply with the release detection requirement. Therefore, this final UST regulation continues to allow vapor and groundwater monitoring as long as owners and operators maintain a site assessment that demonstrates the release detection method meets the requirements in this final UST regulation. Owners and operators of airport hydrant systems and fieldconstructed tanks will have to meet the requirements for vapor monitoring and groundwater monitoring described in subpart K (see section C–2 for additional information). The 1988 UST regulation defined criteria for the use of both release detection methods as explicitly as possible, given the large variation of site-specific conditions at UST sites across the country. EPA supports UST implementing agencies’ efforts to better PO 00000 Frm 00042 Fmt 4701 Sfmt 4700 define site assessment criteria specific to their local geology in addition to what is required in the UST regulation. EPA also acknowledges and supports several UST implementing agencies’ efforts in conducting construction certification and recertification inspections. However, EPA has not analyzed the economic burden construction certification and recertification inspections would place on UST implementing agencies and potentially UST system owners and operators. Therefore, this final UST regulation does not require installation inspections, certification, or recertification inspections of monitoring wells. EPA expects UST implementing agencies will continue reviewing and accepting site assessments according to their program policies. In the event of a confirmed release at an UST site, vapor monitoring and groundwater monitoring are no longer acceptable options for release detection unless a new site assessment for the release detection method is conducted. If a release is confirmed, an owner and operator will have to remediate the site according to 40 CFR part 280, subpart F. Following site remediation, and as long as replacement of the UST system does not trigger the secondary containment requirement, an owner and operator must obtain a new site assessment to verify appropriate use of these methods, if the owner and operator chooses to continue using vapor monitoring or groundwater monitoring as the primary release detection method. Otherwise, owners and operators must use another method of release detection according to subpart D or subpart K. At the time of the 2011 proposed UST regulation, EPA estimated approximately 5 percent of all active UST systems were using vapor monitoring or groundwater monitoring to comply with release monitoring requirements.114 Commenters confirmed that 5 percent of vapor monitoring and groundwater monitoring was accurate. EPA also confirmed that although the methods are used very infrequently in the majority of jurisdictions, there is considerably high use in certain states. Arkansas, Louisiana, and Mississippi have a significant number of owners and operators using vapor monitoring, groundwater monitoring, or a combination of the two methods. 114 E2, Incorporated, memoranda and analyses submitted under Contract EP–W–05–018, U.S. Environmental Protection Agency.

Confirmation of high use in one particular geographic area of the country influenced EPA’s decision to continue allowing use of these methods. EPA agrees with comments about major benefits for UST system owners and operators to use backup release detection, whether it is vapor monitoring, groundwater monitoring, or another method. However, neither the 1988 UST regulation nor this final UST regulation requires a secondary 30 day release detection method. EPA discussed several issues in the 2011 proposed UST regulation that prompted our proposal to no longer allow vapor monitoring and groundwater monitoring as primary methods of release detection. However, the requirement in this final UST regulation for owners and operators to maintain the record of a site assessment for as long as the method is used will address most of these issues. If the site assessment is available when inspecting USTs, UST implementing agencies can confirm proper installation and use of monitoring wells. For example, if inspectors find what they believe to be insufficient numbers of wells or wells improperly located to sufficiently monitor all portions of the tank or piping that routinely contain product, inspectors will be able to reference the site assessment to determine adequacy of the wells. The site assessment will also help UST implementing agencies determine whether certain conditions, which allow users to switch between vapor monitoring and groundwater monitoring due to seasonal variations, have been met. Monitoring wells must be properly constructed and installed to meet all criteria in § 280.43(e) and (f). Wells used for vapor monitoring must allow vapors to collect; wells used for groundwater monitoring must be screened to prevent clogging and intercept the water table at both high and low groundwater conditions while being sealed from the ground to the top of the filter pack. Information regarding acceptability of the same wells used for both methods of release detection must be documented in the site assessment. In the 2011 proposed UST regulation, EPA discussed issues that were specific to vapor monitoring. These issues will be addressed when owners and operators maintain the site assessment for as long as the method is used. The site assessment will contain information on site conditions, such as whether porosity of the surrounding soil is VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 sufficient. The site assessment will confirm that vapors to be monitored will be unaffected by groundwater, rainfall, or soil moisture. Perhaps the most crucial information in the site assessment is the background contamination level at the site. This will allow owners, operators, and implementing agencies to determine whether that level interferes with monitoring methods. It also marks the threshold for determining a release has occurred when monitoring for petroleum hydrocarbons. Maintaining the site assessment also addresses specific groundwater monitoring issues EPA discussed. Groundwater at times can be more than 20 feet from the ground surface, due to seasonal water table variations. This can result in the depth to groundwater requirement not being met. Unless an analysis is performed and valid documentation regarding use of the wells for vapor monitoring during low water table conditions is included in the site assessment, the wells will be restricted for groundwater monitoring use only. In cases where there is no site assessment or an assessment does not sufficiently ensure requirements in § 280.43(e) or (f) are met, UST system owners and operators must reassess the site and maintain documentation required in § 280.43(e)(6) and (f)(7) in order to continue using groundwater or vapor monitoring as a method of release detection. At a minimum, a professional engineer or professional geologist, or equivalent licensed professional with experience in environmental engineering, hydrogeology, or other relevant technical discipline acceptable to the UST implementing agency must sign the new site assessment. EPA understands that in Arkansas, Louisiana, and Mississippi, where the methods are commonly used and account for the majority of use in the country, most UST system owners and operators or the UST implementing agency have sufficient documentation of the site assessment. This means most owners and operators in those states will not need to conduct a new site assessment to comply with this final UST regulation. Owners and operators in other areas of the country may need to conduct a site assessment in order to continue using vapor monitoring or groundwater monitoring. This final UST regulation also addresses another major aspect associated with vapor monitoring and groundwater monitoring methods. Equipment that is used as part of these release detection methods requires proper operation and maintenance in PO 00000 Frm 00043 Fmt 4701 Sfmt 4700 41607 order to provide optimal monitoring results. Operation and maintenance requirements for electronic and nonelectronic equipment are addressed in the release detection equipment testing requirement discussed in section B–5 and the walkthrough inspection requirement in section B–1, respectively. 7. Interstitial Monitoring Results, Including Interstitial Alarms, Under Subpart E This final UST regulation clarifies UST owners’ and operators’ responsibilities regarding interstitial monitoring results, including alarms, under 40 CFR part 280, subpart E. Specifically, EPA is making these changes: • § 280.50(b)—adding liquid in interstitial spaces of secondarily contained UST systems as an example of an unusual operating condition and adding to the list of criteria for not being required to report a suspected release that any liquid in the interstitial space not used as part of the interstitial monitoring method must be removed • § 280.50(c)—clarifying that an alarm during release detection monitoring is subject to the reporting requirement and describing exceptions to the reporting requirement • § 280.52(a)—adding owners and operators as appropriate must conduct secondary containment testing, and clarifying actions UST owners and operators must take if a test confirms a leak into the interstitial space or indicates a release to the environment The 1988 UST regulation implicitly covered interstitial monitoring when reporting suspected releases because it was a method of release detection. This final UST regulation makes changes to explicitly cover interstitial monitoring and reinforce that a leak into an interstitial space of a secondarily contained UST system also indicates a potential threat to the environment; leaks must be investigated, addressed, and as necessary, reported. This final UST regulation requires interstitial monitoring for all new or replaced tanks and piping (see section A–2, Secondary Containment). As new systems are installed, interstitial monitoring will become more widely used as a method of release detection. With this in mind, EPA wants UST owners and operators to clearly understand how interstitial monitoring results, including interstitial alarms, must be handled. In the 1988 UST regulation, EPA indicated that product or water in the E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 41608 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations interstice, and alarms signifying the presence of those conditions, are unusual operating conditions and must be investigated appropriately. However, EPA did not indicate how UST owners and operators were to address discrepancies with interstitial spaces. As a result, some UST owners and operators were uncertain about how best to respond to interstitial monitoring results and alarms associated with interstitial monitoring that indicate a release may have occurred. To alleviate uncertainty for owners and operators, EPA provides information below about interstitial monitoring and responses to alarms. This final UST regulation revises § 280.50(b) by adding interstitial spaces of secondarily contained UST systems and clarifying the presence of liquid in this space as an unusual operating condition unless the liquid is used for interstitial monitoring or meets the requirements described in § 280.43(g)(2)(iv). Water in the interstitial space (presumably from a breach in the secondary wall) and product in the interstitial space (presumably from a breach in the primary wall) are the two typically encountered liquids discovered in the interstice. However, EPA is using the broader term liquid to cover water, product, or other substances in the liquid-phase in the interstitial space. Any liquid in this space not used for interstitial monitoring or not meeting the requirements described in § 280.43(g)(2)(iv) indicates there is an UST system problem that needs to be resolved. As a result, EPA is specifying this as an unusual operating condition and is requiring UST owners and operators investigate and address it. Several commenters suggested changes to § 280.50(b) of the 2011 proposed UST regulation. Suggestions included: Deleting that water or product in the interstice is reportable and clarifying the requirement that the unexplained presence of water or product is an unusual operating condition. Based on comments, EPA in § 280.50(b) of this final UST regulation is using the term liquid, rather than water or product, to address any liquid in the interstitial space. To add clarity to this final UST regulation, EPA is also restructuring the section to provide subsections with separate examples of unusual operating conditions. This final UST regulation also allows owners and operators to not remove or report liquid under two conditions: Within secondary barriers described in § 280.43(g)(2)(iv), as long as interstitial monitoring is not rendered inoperative, or the liquid is VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 used as part of the interstitial monitoring method. EPA is clarifying in § 280.50(c) that an alarm during release detection monitoring, which indicates a potential release or compromise of the interstitial space, is subject to the reporting requirement. UST owners and operators must appropriately address all release detection monitoring alarms. For example, some interstitial monitoring systems will trigger an alarm, which indicates a potential release or that the interstitial space has been compromised. In subpart E, EPA is adding interstitial monitoring to emphasize its importance because the secondary containment requirement for new and replaced systems in section A– 2 will increase the use of interstitial monitoring. UST owners and operators are not required to report alarms from defective system equipment or components or alarms that are investigated and determined to be a non-release. Also, UST owners and operators do not have to report leaks, which are contained in the interstitial space; but owners and operators must investigate and repair problems. Except as provided in § 280.43(g)(2)(iv), any liquid in the interstitial space not used as part of the interstitial monitoring method, such as brine filled, must be removed. Several commenters misunderstood EPA’s discussion regarding reporting alarms. In the 2011 proposed UST regulation, EPA intended that owners and operators need to investigate all alarms, but only report confirmed releases and suspected releases that could not be ruled out by an investigation. Commenters suggested these changes to EPA’s 2011 proposed UST regulation at § 280.50(c): Deleting language pertaining to alarms; changing language regarding the time allowed to repair, recalibrate, or replace defective system equipment; and including an exception for reporting alarms that have been confirmed to be false alarms. Based on comments, EPA in § 280.50(c) of this final UST regulation is expanding and describing exceptions to reporting monitoring results, including investigation of an alarm from a release detection method that indicates a release may have occurred. EPA is adding secondary containment testing, as appropriate, to the release investigation and confirmation steps in § 280.52(a) of the final UST regulation. EPA thinks it is important to clarify actions UST owners and operators must take if a test confirms a leak into the interstitial space or indicates a release has occurred. If a leak into the interstice is confirmed, an UST owner and PO 00000 Frm 00044 Fmt 4701 Sfmt 4700 operator must correct or address the problem. In addition to options listed in the 1988 UST regulation, this final UST regulation includes closure as an option when an owner and operator confirms a release. Nothing in this final UST regulation changes the requirement in subpart F for an UST owner and operator to take corrective action if a release occurred. In the 2011 proposed UST regulation, EPA suggested that UST owners and operators follow integrity test requirements, now referred to as secondary containment testing, of the interstitial area. Many commenters noted that tank tightness testing or line tightness testing may be more appropriate tests to confirm a suspected release under certain circumstances, and UST system owners and operators should be allowed the choice of determining which test to use. EPA agrees and is revising § 280.52(a) to indicate use of secondary containment testing as appropriate. EPA received several comments about the terms release and leak used throughout the 2011 proposed UST regulation and the 1988 UST regulation. Historically, EPA used these terms interchangeably. As a result of EPA’s new secondary containment and interstitial monitoring requirement (see section A–2, Secondary Containment), there is now a subtle but important distinction between the terms. The term release is defined in the Solid Waste Disposal Act. EPA provides the same definition of release in the UST regulation at § 280.12. Release means any spilling, leaking, emitting, discharging, escaping, leaching or disposing from an UST into groundwater, surface water or subsurface soils. A release always reaches the environment. The term leak in this final UST regulation is a more general term that includes both cases of when a regulated substance enters into a contained area (such as secondary containment) but has not yet reached the environment and when a regulated substance reaches the environment (a release). Therefore, the term release is a subset of the more general term leak. Note that leaks and releases have investigation and reporting requirements in subpart E. As a result of distinguishing between a leak and a release, EPA is clarifying the definition of release detection. The 1988 UST regulation defined release detection as determining whether a release of a regulated substance occurred from the UST system into the environment or into the interstitial space between the UST system and its secondary barrier or secondary E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations containment around it. This final UST regulation revises the definition of release detection to clarify regulated substances entering into the interstitial space are leaks instead of releases. This final UST regulation defines release detection as determining whether a release of a regulated substance occurred from the UST system into the environment or a leak occurred into the interstitial space between the UST system and its secondary barrier or secondary containment around it. This change allows EPA to continue to use the term release detection as it applies to both leaks and releases. E. General Updates tkelley on DSK3SPTVN1PROD with RULES2 1. Incorporate Newer Technologies Since EPA promulgated the 1988 UST regulation, newer tank, piping, and release detection technologies have been developed and are being used. EPA is incorporating several of these newer technologies in this final UST regulation. In addition, because the 1988 UST regulation closure requirements unintentionally restrict use of a newer tank within a tank technology, EPA is revising closure requirements to provide additional flexibility for implementing agencies to allow field-constructed tank technologies that construct a tank within an existing closed tank. However, EPA is not specifically including field-constructed tank within a tank technologies in the new tank standards section in § 280.20 of the final UST regulation, because the tank construction technologies currently covered in this section include both factory constructed and fieldconstructed technologies. Note that § 280.20(d) requires new UST systems, including tank within a tank technologies, to be properly installed according to a code of practice developed by a nationally recognized association or independent testing laboratory and the manufacturer’s instructions. Clad and Jacketed Tanks This final UST regulation adds steel tanks that are clad or jacketed with a non-corrodible material to the list of specific new tank design and construction options for UST systems. EPA estimates 10 percent of regulated tanks today are jacketed with a noncorrodible material and 18 percent are clad with a non-corrodible material.115 115 E2, Incorporated, memoranda and analyses submitted under Contract EP–W–05–018, U.S. Environmental Protection Agency. Underground Storage Tanks/Leaking Underground Storage Tanks Analytical And Technical Support. These VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 The 1988 UST regulation allowed a steel-fiberglass-reinforced-plastic composite tank (also called a fiberglass clad tank), but did not specifically include other non-corrodible claddings. In addition to fiberglass, manufacturers in 2014 are using other non-corrodible materials claddings for steel tanks, which are listed by UL standard 1746, External Corrosion Protection Systems for Steel Underground Storage Tanks. These tank technologies are effective at preventing corrosion of the portion of the steel tank shell in contact with the ground. EPA considers a cladding to be a non-corrosive dielectric material, bonded to a steel tank with sufficient durability to prevent external corrosion during the tank’s life. Because they were not commonly used at the time, EPA did not include jacketed tanks in the 1988 UST regulation. These tanks are now: More commonly used; UL 1746 listed for external corrosion protection; and effective in preventing corrosion of the steel tank shell. EPA considers the tank jacket to be a non-corrosive dielectric material that: is constructed as secondary containment or jacketed around a steel tank; has sufficient durability to prevent external corrosion of the steel tank shell during a tank’s life; and prevents a regulated substance released from the primary steel tank wall from reaching the environment. Non-Corrodible Piping The 1988 UST regulation allowed fiberglass-reinforced plastic piping, but did not specifically include other noncorrodible piping options such as flexible plastic piping. Both fiberglass and flexible plastic piping are listed under the UL 971 standard, Nonmetallic Underground Piping for Flammable Liquids. Non-corrodible piping not made of fiberglass-reinforced plastic (in particular, flexible plastic piping) was installed at UST sites beginning in the 1990s and has evolved over the past 20 years. Flexible plastic piping is made of various non-corrodible materials, such as polyethylene and polyurethane. EPA estimates at least 13 percent of regulated piping currently installed is made of non-corrodible materials that are not fiberglass-reinforced plastic.116 This final UST regulation revises fiberglassreinforced piping to be non-corrodible supporting materials are located in the docket EPA– HQ–UST–2011–0301. 116 E2, Incorporated, memoranda and analyses submitted under Contract EP–W–05–018, U.S. Environmental Protection Agency.

Release Detection Technologies The 1988 UST regulation allowed UST owners and operators to use other methods that meet release detection performance criteria listed at § 280.43(h). Although continuous intank leak detection (CITLD) and SIR were allowed under § 280.43(h), EPA is including both by name and providing specific performance criteria in this final UST regulation for the reasons described below. CITLD The 1988 UST regulation allowed ATG systems as a recognized method of release detection. However, ATG systems were generally listed with performance requirements consistent with performing a static test. ATG systems rely on system down time and the absence of product delivery or dispensing activities to perform release detection. In static testing mode, an ATG system analyzes product level and determines whether a leak is present during that down time. UST owners and operators also use ATG systems as a means of continually monitoring tanks for potential releases. CITLD has evolved as a reliable means of providing release detection equivalent to other methods specified in § 280.41. Within this category of methods, this final UST regulation allows continuous in-tank methods where the system incrementally gathers measurements to determine a tank’s leak status within the 30-day monitoring period. One commenter asked EPA to further clarify the term CITLD. That commenter said EPA presented language in the 2011 proposed UST regulation that confused CITLD, continuous statistical leak detection (CSLD), and SIR because each is a statistically based release detection method. EPA agrees with the commenter and is clarifying use of the term CITLD, which encompasses all statistically based methods where the system incrementally gathers measurements on an uninterrupted or nearly uninterrupted basis to determine a tank’s leak status. Currently, there are two major groups that fit into this category: CSLD (also referred to as continuous automatic tank gauging methods) and continual reconciliation. Both groups typically use sensors permanently installed in the tank to obtain inventory measurements. They are combined with a microprocessor in E:\FR\FM\15JYR2.SGM 15JYR2 41610 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations the ATG system or other control console that processes the data. Continual reconciliation methods are further distinguished by their connection to dispensing meters that allow for automatic recording and use of dispensing data in analyzing tanks’ leak status. SIR, which we describe below, is not a continually operating method that fits into the CITLD category. This final UST regulation formally recognizes CITLD as a release detection method in § 280.43(d). Per § 280.41, a conclusive pass or fail result must be obtained within the 30-day monitoring period. All monitoring records must be maintained according to § 280.45. Another method of release detection is required in the event of an inconclusive result. For example, in the event of an inconclusive result, UST owners and operators may perform an in-tank static test using an ATG system or use another method of release detection. tkelley on DSK3SPTVN1PROD with RULES2 SIR This final UST regulation adds SIR as a release detection method and provides performance criteria for its use. SIR must: • Report a quantitative result with a calculated leak rate; • Be capable of detecting a leak rate of at least 0.2 gallon per hour or a release of 150 gallons within a 30-day period with a probability of detection of not less than 0.95 and a probability of false alarm of no greater than 0.05; and • Use a threshold that does not exceed one-half the minimum detectable leak rate. A quantitative result with a calculated leak rate is necessary to effectively perform release detection using SIR. Some SIR methods are qualitative based methods that simply provide a result of pass or fail without any additional information for UST owners and operators to gauge the validity of reported results. Based on information in the NWGLDE list,117 approximately 85 percent of SIR methods listed are quantitative-based methods. Many state UST implementing agencies already only allow quantitative methods. This final UST regulation only allows quantitative SIR as an option for meeting the release detection requirement. Consistent with the performance criteria described in the other methods option for release detection, this final UST regulation maintains the performance standards of a 0.2 gallon per hour release or a release of 150 117 National Work Group On Leak Detection Evaluations’ List Of Leak Detection Evaluations For Storage Tank Systems: https://www.nwglde.org/. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 gallons within a 30-day period with a probability of detection of 0.95 and a probability of false alarm of 0.05. The 2011 proposed UST regulation did not include the additional standard of 150 gallons within a 30-day period for SIR. EPA agrees with the commenter who noted the importance of the 150 gallons criteria if SIR methods are used for monitoring piping for release detection; as a result, we are retaining this performance standard for SIR in the final UST regulation because EPA and some other implementing agencies allow UST system owners and operators to use SIR for piping release detection. Like other release detection methods, SIR must be capable of detecting a release of 0.2 gallon per hour or less with a probability of detection (Pd) of at least 0.95 and probability of false alarm (Pfa) of no more than 0.05. In a normal probability distribution, SIR data typically analyzed through the calculation of the reportable values of minimum detectable leak rate (MDL) and the leak declaration threshold (T) are related as follows: • MDL is always greater than T • Pd = (1-Pfa), then MDL = 2 times T (i.e., T = 1⁄2 MDL) Any analysis of data indicating a threshold value greater than one-half minimum detectable leak rate should be investigated as a suspected release. One commenter asked EPA to further clarify SIR. The commenter said EPA presented language in the 2011 proposed UST regulation that confused statistically based release detection methods currently in use. EPA agrees and is modifying the description of SIR in this final UST regulation at § 280.43(h) to narrow the focus of statistically based methods, which fit under this section. SIR encompasses only those statistically based methods where inventory data is gathered over a period and typically provided to a vendor who analyzes the data to determine the leak status of the tank. These methods do not include systems that incrementally gather measurements on an uninterrupted or nearly uninterrupted basis to determine the tank’s leak status described in § 280.43(d) under continuous in tank leak detection. This final UST regulation addresses these issues associated with SIR: • SIR is not the same as inventory control Æ Historically, users, vendors, and regulators have incorrectly associated SIR with inventory control in § 280.43(a). SIR is more sophisticated than inventory control and not subject to the same PO 00000 Frm 00046 Fmt 4701 Sfmt 4700 requirement to combine it with tank tightness testing and limit its use to 10 years. Section 280.50(c)(3) allows owners and operators to use a second month of inventory control data to confirm initial possible failure results. However, this allowance does not apply to SIR. Therefore, any failed SIR result must be investigated as a suspected release. Also, in the event of an inconclusive result, UST owners and operators must use another method of release detection to determine the leak status of the tank. • Results for release detection, including SIR, are required within the 30-day monitoring period Æ EPA considered including a requirement in the final UST regulation that UST owners and operators obtain a record of SIR results within 30 days. However, this requirement is already covered in the release detection requirements. As § 280.41(a)(1) states, ‘‘Tanks . . . must be monitored for releases at least every 30 days using one of the methods listed in § 280.43(d) through (i) . . .’’ In this final UST regulation, EPA is adding a subsection to formally recognize SIR. A definitive result of pass or fail that identifies the tank’s leak status is required within the 30-day monitoring period for all release detection methods, including SIR. • Owners and operators must use another method of release detection if SIR results are inconclusive Æ For years, implementing agencies have been concerned about inconclusive results when using SIR for release detection. In 1993, EPA issued a policy regarding inconclusive SIR results,118 which says all methods used to meet release detection requirements in § 280.41 must obtain a conclusive result of pass or fail within the 30day monitoring period. All monitoring records must be maintained according to § 280.45. For SIR, this means UST owners and operators must obtain a report determining release status within the 30-day monitoring period. Another method of release detection is required when results are inconclusive; prior to sufficient data gathered to generate an initial report at startup; or when a report is not available for any month of 118 UST Technical Compendium, question and answer number 21:https://epa.gov/oust/compend/ rd.htm. E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations monitoring. Owners and operators have not performed release detection until the release status of the UST system has been conclusively determined. • Initial SIR report at startup Æ SIR methods need to gather data over a period in order to determine whether the tank is leaking. In some cases, implementing agencies have addressed significant lag times between when data is collected and when a tank status determination is available to owners and operators. NWGLDE’s list of third-party evaluated methods indicates the data collection period required for SIR methods ranges from 15 to 90 days. However, most methods require between 23 and 30 days to gather sufficient measurements that provide an accurate result. Any method that goes beyond a 30-day monitoring period is inconsistent with and does not meet the release detection requirement. It is imperative that UST owners and operators determine the status of their tanks within the established monitoring period to avoid increased risk of releases. Therefore, owners and operators must use another release detection method at least once every 30 days until a SIR result is obtained. After that, owners and operators must have a SIR result at least once every 30 days. • Meeting the 30-day monitoring requirement Æ EPA received several comments regarding the lack of timeliness associated with determining whether a leak exists when using SIR. In many instances, monitoring results are not produced until the next monitoring period or well beyond. These commenters also provided several suggestions for EPA to address the lag time between UST owners and operators collecting leak detection data and receiving late reporting on the leak status of the tank. EPA reiterates its established regulatory requirement that tanks must be monitored for releases at least once every 30 days. Æ Commenters provided other options for how owners and operators can meet the release detection requirement. One possible option is for EPA to require owners and operators perform a SIR analysis every 15 days using the last 30 days of data. This option results in a more frequent analysis of the UST system’s leak status. EPA agrees this option would allow owners and operators to meet the VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 release detection requirement. Another option suggested was for EPA to add a requirement that SIR results must be returned to owners within seven days of the end of the data collection period; other commenters indicated various other times. EPA disagrees with this option because it would not meet the requirement to conduct release detection at least once every 30 days. Providing additional time for one method to determine whether a leak has occurred would be both unfair to UST system owners and operators using other release detection methods, as well as result in decreased environmental protection. To meet the release detection requirement for SIR, owners and operators could conduct a more frequent analysis, as one commenter suggested, or send data more expeditiously by electronic means. EPA is retaining the 30-day release detection requirement, which allows owners and operators to use whatever method they choose, as long as the method meets performance standards. UST system owners and operators can discuss changing their methods or data collection procedures with their SIR vendors in order to meet EPA’s release detection requirement. Interstitial Monitoring The 2011 proposed UST regulation included three methods of continuous interstitial monitoring—vacuum, pressure, and liquid-filled methods—in § 280.43(g). EPA proposed these methods in conjunction with the periodic secondary containment testing requirement. Based on comments, EPA removed references to continuous interstitial monitoring in this final UST regulation. Because continuous interstitial monitoring is not discussed in this final UST regulation, EPA does not include language pertaining to continuous vacuum, pressure, or liquidfilled methods of interstitial monitoring in § 280.43(g). This does not impact release detection methods allowed under § 280.43(g). 2. Updates to Codes of Practice Listed in the UST Regulation This final UST regulation updates the codes of practice (also called standards or recommended practices) listed in the 1988 UST regulation to reflect new codes, changes to code names, and new nationally recognized associations and independent testing laboratories. The 1988 UST regulation relied on codes of practice developed by nationally PO 00000 Frm 00047 Fmt 4701 Sfmt 4700 41611 recognized associations or independent testing laboratories to implement many of the requirements. EPA will continue to rely on codes of practice in this final UST regulation. EPA reviewed information from more than 25 code making groups on more than 200 codes of practice, which have been developed or revised since the 1988 UST regulation.119 As a result, EPA is: • Updating titles and designations of existing codes of practice; • Adding applicable codes of practice developed after the 1988 UST regulation was finalized; • Moving codes of practice that were misplaced in the 1988 UST regulation; and • Removing codes of practice that: Æ Are out of date, no longer available, withdrawn, or rescinded; Æ No longer provide any information appropriate to or relevant to the final UST regulation where it was referenced; or Æ Are no longer needed. For example, EPA listed the Association for Composite Tanks ACT– 100 tank standard in § 280.20(a)(3) of the 1988 UST regulation as a code of practice for meeting the clad tank requirement. EPA is removing this code of practice from this final UST regulation because both the association and code of practice no longer exist. In several cases, EPA is moving a code of practice from one section of the final UST regulation to another. For example, EPA is moving Steel Tank Institute Standard F841, Standard for Dual Wall Underground Steel Storage Tanks from § 280.43(g)—interstitial monitoring to § 280.20(a)(2), which covers steel tanks. EPA thinks it makes more sense for this to be included under the UST design and construction standards, rather than as a release detection standard. EPA used similar rationale when relocating other codes of practice in this final UST regulation. As in the preamble to the 1988 UST regulation, this final UST regulation does not require use of a specific version or edition of any code. The consensus codes are frequently revised and updated. EPA recognizes that requiring use of the most recent edition of a code of practice would cause undue confusion in the regulated community. For example, owners and operators install UST systems according to codes 119 E2, Incorporated, memoranda and analyses submitted under Contract EP–W–05–018, U.S. Environmental Protection Agency. Underground Storage Tanks/Leaking Underground Storage Tanks Analytical And Technical Support. These supporting materials are located in the docket EPA– HQ–UST–2011–0301. E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 41612 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations of practice current at the time of installation, but may not have equipment in the ground that meets codes that are current 10 years later. EPA concludes that the industry codes in effect at the date of publication of this final UST regulation are protective of human health and the environment. Using future editions of codes instead of editions now in effect is not required, but is encouraged; updated codes will probably provide for newer, more effective technologies and practices. Using past codes, which have been replaced by new editions prior to the effective date of this final UST regulation, is not allowed because some past recommended industry practices may not represent current codes of practice or may not adequately cover the regulatory requirement. Consistent with the preamble to the 1988 UST regulation, this final UST regulation interprets the term nationally recognized organization to mean a technical or professional organization that has issued standards formed by the consensus of its members. The organization should consider all relevant viewpoints and interests, including those of consumers and future or existing potential industry participants. The resulting standards should be widely accepted and based on a broad range of technical information, and performance criteria should be central elements of the resulting standards. EPA regards the following organizations, whose codes of practice are listed in this final UST regulation, as examples of nationally recognized organizations: American Petroleum Institute (API) American Society for Testing and Materials (ASTM) Fiberglass Tank and Pipe Institute (FTPI) National Association of Corrosion Engineers (NACE) National Fire Protection Association (NFPA) National Leak Prevention Association (NLPA) Petroleum Equipment Institute (PEI) Steel Tank Institute (STI) Underwriters Laboratory (UL) EPA received broad support for updating the codes of practice listed in the final UST regulation. Several commenters pointed out errors to titles or designations in the 2011 proposed UST regulation. This final UST regulation corrects these errors. EPA received comments on the 2011 proposed UST regulation asking that we add or remove several codes of practice. EPA reviewed PEI’s recommended practice for testing and verification of VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 spill, overfill, leak detection, and secondary containment equipment (RP 1200), and in this final UST regulation is including it in areas where testing or inspecting UST equipment is required. EPA also reviewed and is including PEI’s recommended practice for the inspection and maintenance of UST systems (RP 900) in the walkthrough inspections portion of this final UST regulation. EPA is not including the Canadian code for installing fiber reinforced plastic linings (ULC/ORD– C58.4–05), because this final UST regulation no longer allows owners and operators to install internal linings to meet the corrosion protection upgrade. Owners may continue using internal linings for other reasons such as compatibility or secondary containment; but EPA determined there are no appropriate areas in this final UST regulation to list lining codes of practice for those purposes. Also, EPA is not including PEI’s recommended practice for the inspection and maintenance of motor fuel dispensing equipment (RP 500), because it is a standard for inspecting motor fuel dispensing equipment and Subtitle I of the SWDA does not give EPA the authority to regulate aboveground equipment such as motor fuel dispensing equipment. Finally, EPA is not including STI’s storage tank maintenance standard (R– 111) as an option for periodic walkthrough inspections because the content of the 2011 version of this code of practice only focused on water and contaminants in the tank along with compatibility. Except for a monthly inspection checklist, this code of practice does not describe how to conduct a periodic walkthrough inspection. If STI changes this code of practice, implementing agencies may determine whether the newer version is adequate for meeting the periodic walkthrough inspection requirement in this final UST regulation. In the 2011 proposed UST regulation, EPA asked for input on whether the requirement to follow codes of practice and manufacturer’s instructions under the installation requirements in § 280.20(d) should apply to just tanks and piping (as stated in the 1988 UST regulation) or apply to the UST system as a whole. Both the 1988 UST regulation and this final UST regulation define UST system as the underground storage tank, connected underground piping, underground ancillary equipment, and containment system, if any. Commenters strongly supported requiring installation of the UST system, rather than just tanks and piping, according to a code of practice PO 00000 Frm 00048 Fmt 4701 Sfmt 4700 developed by a nationally recognized association or independent testing laboratory and according to manufacturer’s instructions. For these reasons, this final UST regulation replaces tanks and piping with UST system in § 280.20(d). 3. Updates To Remove Old Upgrade and Implementation Deadlines This final UST regulation removes references to the 1998 deadline and old phase in schedules, while continuing to allow testing of corrosion protection and release detection. These changes acknowledge that the 1998 deadline for upgrading UST systems with release prevention and the 1990s release detection and financial responsibility deadlines passed more than a decade ago. In addition, as of 2010 implementing agencies have inspected all regulated UST systems at least once for compliance with release detection, release prevention, and financial responsibility requirements. EPA will no longer allow owners and operators to upgrade UST systems if they never met the 1998 upgrade requirements, unless the implementing agency determines the UST system is acceptable to upgrade. Owners and operators must permanently close nonupgraded UST systems according to the closure requirements in subpart G. Nonupgraded UST systems are older and have been in the ground for more than two decades. In addition, metal USTs and piping without corrosion protection pose a significant risk to human health and the environment, because unprotected metal in contact with soil corrodes. EPA is allowing implementing agencies to make case-by-case determinations on when to allow upgrades. EPA does not expect implementing agencies to allow continued use of tanks or piping not upgraded with corrosion protection. However, some implementing agencies may decide to allow owners and operators of UST systems with corrosion protection, but without spill or overfill prevention, to add spill or overfill prevention instead of requiring permanent closure. EPA will continue to allow UST systems with field-constructed tanks and airport hydrant systems to be upgraded with spill, overfill, and corrosion protection under subpart K of the UST regulation. See section C–2 for additional information on upgrading these UST systems. To meet the release detection requirement, § 280.41 of the 1988 UST regulation allowed owners and operators of USTs not upgraded with corrosion protection to use a E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations combination of monthly inventory control with annual tank tightness testing until December 22, 1998. Since owners and operators no longer have the option to use inventory control and annual tightness testing, EPA is removing this option from this final UST regulation. In response to comments received, EPA is removing the definition of petroleum marketing firm from subpart H of this final UST regulation. EPA only used the term petroleum marketing firm in the compliance dates section as it related to when these firms needed to meet the financial responsibility requirements. Since the compliance dates for conventional UST systems have passed more than a decade ago, the term no longer needs to be defined. tkelley on DSK3SPTVN1PROD with RULES2 4. Editorial Corrections and Technical Amendments This final UST regulation includes editorial corrections and technical amendments to the 1988 UST regulation. Editorial corrections include: Correcting misspellings; capitalizing words; removing unused acronyms; using conventional number formatting; and appropriately referring to parts, subparts, sections, and paragraphs. In addition, this final UST regulation adds technical amendments, which include updating the final UST regulation to incorporate statutory changes that occurred since the 1988 UST regulation was promulgated and clarifying longstanding Agency interpretations and policies. EPA is making the following technical amendments in this final UST regulation: • § 280.10(c)(4)—EPA is revising the Nuclear Regulatory Commission citation to be consistent with the Spill Prevention Control and Countermeasures requirements in 40 CFR part 112. This final UST regulation partially excludes emergency generator systems at nuclear power generation facilities licensed by the Nuclear Regulatory Commission that are subject to Nuclear Regulatory Commission requirements regarding design and quality criteria, including but not limited to 10 CFR part 50. EPA originally proposed only deleting appendix A from the regulatory citation. However, EPA agrees with commenters that using language consistent with the Spill Prevention Control and Countermeasures requirements in 40 CFR part 112 provides clarity and consistency for owners and operators of emergency generator UST systems at nuclear power generation facilities. • § 280.12—EPA is revising exclusion (ii) of the definition of UST to VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 incorporate a revision in section 9001 of the Solid Waste Disposal Act. • This final UST regulation adds a technical amendment to § 280.43(b), which codifies longstanding Agency policy adding additional flexibility for using manual tank gauging. This change updates UST capacity allowances and testing durations when using manual tank gauging. Since 1990, EPA allowed these deviations from the 1988 UST regulation through policy and included them in outreach publications. • The 2011 proposed UST regulation removed the requirement for inventory control for the automatic tank gauging release detection method in § 280.43(d) because some interpreted the language as requiring both inventory control and automatic tank gauging. However, EPA agrees with commenters who indicated the language is necessary to ensure automatic tank gauging equipment meets inventory control performance standards in § 280.43(a). More specifically, EPA is keeping the regulatory language to ensure owners and operators continue to measure for water as described in the inventory control requirement. This final UST regulation departs from the proposal and retains language established in the 1988 UST regulation that automatic tank gauging equipment also must meet the inventory control requirements. This final UST regulation does not require owners and operators to perform inventory control in addition to automatic tank gauging. • This final UST regulation expressly states which new operation and maintenance requirements owners and operators do not have to meet for UST systems in temporary closure. Owners and operators of temporarily closed UST systems that are empty do not have to perform the following periodic release detection operation and maintenance testing and inspections in subparts C and D: 30 day release detection checks, annual sump checks, and annual handheld release detection checks described in the walkthrough inspection section (see section B–1); testing of containment sumps used for interstitial monitoring described in the secondary containment testing section (see section B–4); and testing of release detection equipment described in the release detection equipment testing section (see section B–5). These requirements are unnecessary as long as the temporarily closed UST system is empty because release detection is not required in the first place. In addition, owners and operators of any UST system in temporary closure are not required to conduct the following periodic operation and maintenance PO 00000 Frm 00049 Fmt 4701 Sfmt 4700 41613 testing and inspections for spill prevention equipment and overfill prevention equipment in subpart C: Spill prevention equipment testing (see section B–2); overfill prevention equipment inspections (see section B– 3); or spill prevention equipment checks described in walkthrough inspections (see section B–1). Spill and overfill testing or inspections are not required for UST systems in temporary closure because those systems are not receiving deliveries of regulated substances. Finally, as a conforming amendment, this final UST regulation adds subpart K to the release detection citation because new release detection requirements for field-constructed tanks and airport hydrant systems are included in that subpart. • This final UST regulation amends the definition of the term accidental release in § 280.92 so it matches the definition described in the preamble to the 1988 UST regulation for the financial responsibility requirements (53 FR 43334). EPA intended the definition in the preamble to be included in the 1988 UST regulation, but failed to include the concept of releases as a result of operating the UST. Through this amendment, EPA is clarifying that owners and operators are required to have financial responsibility for releases arising from operating USTs (including releases due to filling USTs and releases occurring at dispensers). • § 280.94(a)(1)—EPA proposed to include the local government option citations in this section. However, those options are not included in this final UST regulation because they are already included in § 280.94(a)(2). • § 280.97(b)(1) and (2)—EPA added the local government options as part of the reference since those options are also viable financial responsibility mechanisms. • To make the local government bond rating test consistent with the requirements of the financial test in § 280.94, this final UST regulation adds a new subsection to § 280.104. • To ensure the definition of UST technical standards in subpart I, Lender Liability, includes all of the preventative and operating requirements in this final UST regulation, EPA revised the definition to include subparts J and K as part of the preventative and operating requirements under 40 CFR part 280. • To add clarity about the statement for shipping tickets and invoices in appendix III, this final UST regulation revises the appendix. • Finally, the final UST regulation revises sections that use the terms operating life or properly closed to be permanently closed or when a change- E:\FR\FM\15JYR2.SGM 15JYR2 41614 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations in-service occurs; this amendment will clearly indicate when the regulated operating life of an UST system ends. This final UST regulation does not define an operating life or proper closure. Rather, it describes permanent closure and change-in-service. F. Alternative Options EPA Considered In developing this final UST regulation (hereafter the Selected Option), EPA considered and evaluated variations of a subset of the regulatory requirements using two alternative options (hereafter Option 1 and Option 2). The table below highlights differences between the Selected Option and Options 1 and 2. Some of the regulatory requirements do not vary across the options (for example, notification of ownership changes is required in all three). As a result, regulatory changes discussed earlier in the preamble, but not listed here, mean those changes are in effect in all three options. Overall, Options 1 and 2 consist of regulatory changes that are more and less stringent, respectively, than those of the Selected Option.

For example, the 30-day walkthrough inspections in the 2011 proposed UST regulation included monthly check of sumps. Please see the 2011 proposed UST regulation for details. tkelley on DSK3SPTVN1PROD with RULES2 Below we explain Options 1 and 2, as well as our rationale for each. (Note that EPA conducted a regulatory impact analysis for all three options. The results are discussed in the RIA document titled Assessment of the Potential Costs, Benefits, and Other Impacts of the Final Revisions to EPA’s Underground Storage Tank Regulations, which is available in the docket for this action.) EPA’s Rationale for Option 1 EPA considered keeping walkthrough inspections as described in the 2011 proposed UST regulation. However, based on concerns from commenters regarding the proposed walkthrough inspection requirements, EPA decided to revise the components of the walkthrough inspection. See section B– 1 for details regarding this final UST regulation on walkthrough inspections. EPA also considered requiring annual inspections of overfill prevention equipment, annual spill prevention equipment tests, and annual VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 containment sump testing. After reviewing comments, considering the benefits of establishing one consistent implementation time frame across as many regulatory requirements as possible, as well as assessing the cost of requiring annual tests and inspections, EPA is requiring owners and operators inspect overfill prevention equipment and test spill prevention equipment and containment sumps once every three years. This balances the benefits of ensuring properly functioning equipment with the potential administrative burden and costs imposed on owners and operators. When considering operability checks for release detection equipment, EPA examined the possibility of keeping the operability checks as described in the 2011 proposed UST regulation. However, based on comments, EPA decided to revise some components of the operability checks. This resulted in allowing owners and operators to perform some release detection checks PO 00000 Frm 00050 Fmt 4701 Sfmt 4700 on an annual basis instead of every 30 days. See section B–5 for details regarding release detection equipment testing. EPA also considered maintaining the 2011 proposed option of a five year phase out of groundwater and vapor monitoring as permissible release detection methods. Based on concerns from states where groundwater and vapor monitoring are used frequently by owners and operators, EPA is retaining groundwater and vapor monitoring as long as owners and operators demonstrate proper installation and performance through a site assessment that must be maintained as long as the methods are used. See section D–6 for details regarding groundwater and vapor monitoring. EPA also considered maintaining its 2011 proposed requirements for release detection of emergency generator tanks and for demonstrating compatibility. However, as discussed in earlier sections (C–1 for emergency generator tanks and D–4 for compatibility), EPA is E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 revising these requirements in response to comments. For emergency generator tanks, we are revising the implementation time frame for consistency with other implementation dates. For compatibility, EPA is removing the recordkeeping requirement for new installations to make it easier for owners and operators to be in compliance. EPA is also adding a list of equipment that must demonstrate compatibility with storing ethanol blends greater than 10 percent or biodiesel blends greater than 20 percent, or any other regulated substance identified by the implementing agency. This will help owners and operators understand which UST equipment must be demonstrated to be compatible. Lastly, EPA considered requiring owners and operators of airport hydrants systems and field-constructed tanks submit a one-time notice of existence in addition to reporting confirmed releases to the implementing agency. Owners and operators of these systems would not be subject to any additional regulatory requirements under Option 1. After weighing the availability of release detection options for these systems, the applicability of other requirements in this final UST regulation, and the potential human health and environmental impact of releases from these systems, EPA is fully regulating these systems. See C–2 for EPA’s rationale for regulating airport hydrant systems and field-constructed tanks. EPA’s Rationale for Option 2 In comparing costs with benefits of the final regulatory changes, EPA weighed different frequencies for walkthrough inspections and periodic equipment inspections or tests. EPA assessed quarterly walkthrough inspections, and not requiring overfill prevention equipment inspections and containment sump testing as ways to reduce potential cost impacts on owners and operators. Compared to the 30-day requirement, quarterly walkthrough inspections would reduce costs to owners and operators. However, EPA thinks a period less frequent than 30 days for walkthrough inspections would considerably reduce benefits. High operator turnover and the frequency of deliveries both contribute to the need for 30-day walkthrough inspections. With that in mind, today EPA is requiring 30-day walkthrough inspections so owners and operators can consistently and routinely verify proper spill prevention and release detection performance. This will ensure problems are detected before a release occurs. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 EPA also considered not requiring overfill prevention equipment inspections and containment sump testing. However, as explained in sections B–3, Overfill Prevention Equipment Inspections and B–4, Secondary Containment Tests, tank overfills and containment sump areas account for a significant amount of releases from UST systems. As a result, EPA is requiring overfill prevention equipment inspections and containment sump testing (for containment sumps used for interstitial monitoring) once every three years. Overfill prevention equipment inspections will ensure overfill prevention equipment is operating properly. Similarly, containment sump testing will ensure that containment sumps used for interstitial monitoring will be liquid tight. To reduce total compliance costs of this final UST regulation for owners and operators, EPA considered allowing continued use of flow restrictors in vent lines (that is, ball float valves) as an acceptable form of overfill prevention equipment. After considering public comments, EPA maintains its position that vent line flow restrictors present problems for operability and safety reasons. As described in section D–1, EPA is eliminating ball float valves as an overfill prevention equipment option for all new tanks and when overfill prevention equipment is replaced in existing tanks. EPA considered maintaining the existing requirements for groundwater and vapor monitoring, in particular retaining the two as permissible release detection methods with no changes to the 1988 UST regulation. However, given the numerous concerns that have arisen over the years regarding these two release detection methods, such as misapplications and improper designs of monitoring wells, EPA is retaining these two release detection methods only if owners and operators demonstrate proper installation and performance through a site assessment. See section D–6 for details regarding groundwater and vapor monitoring. EPA also considered only retaining the current requirement for owners and operators to use UST systems made of or lined with materials that are compatible with the substance stored in the UST system. However, EPA understands that the chemical and physical properties of ethanol and biodiesel can be more degrading to certain UST materials than petroleum alone. As the use of ethanol- and biodiesel-blended fuels increases, EPA is concerned that not all UST system equipment or components are PO 00000 Frm 00051 Fmt 4701 Sfmt 4700 41615 compatible with these fuels. Therefore, EPA is requiring owners and operators demonstrate compatibility of certain UST system components when storing ethanol blends greater than 10 percent and biodiesel blends greater than 20 percent. Owners and operators can demonstrate compatibility of required components by using one of the three options described in this final UST regulation. See section D–4 for details regarding compatibility. Finally, EPA considered maintaining deferrals for airport hydrant systems and field-constructed tanks. However, as explained above, after weighing the availability of release detection options for these systems, the applicability of the other requirements in this final UST regulation, and the potential human health and environmental impact of releases from these systems, EPA is fully regulating these systems. See C–2 for EPA’s rationale for regulating airport hydrant systems and field-constructed tanks. V. Updates to State Program Approval Requirements EPA is making changes to the 1988 SPA regulation (40 CFR part 281) to make it consistent with certain Energy Policy Act requirements and certain revisions to the 1988 UST regulation (40 CFR part 280). Commenters generally supported EPA changing portions of the 1988 SPA regulation and making it consistent with revisions to the 1988 UST regulation. Commenters supported EPA keeping the general format of the 1988 SPA regulation and not making the final SPA regulation as explicit or prescriptive as this final UST regulation. EPA is making these substantive changes to the 1988 SPA regulation. • § 281.12(b)—adding definitional exceptions for several Energy Policy Act definitions • §§ 281.30(a), 281.33(c)(2), and 281.33(d)(3)—require secondary containment for new or replaced tanks and piping and under-dispenser containment for new motor fuel dispenser systems for UST systems located within 1,000 feet of a potable drinking water well or community water system, unless a state requires manufacturer and installer financial responsibility according to section 9003(i)(2) of the Solid Waste Disposal Act • §§ 281.30(a)(1) and 281.33(d)(3)— exclude safe suction piping, airport hydrant system piping, and fieldconstructed tank piping from being required to meet the secondary containment and interstitial monitoring requirements E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 41616 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations • § 281.30(b)—eliminate flow restrictors for new or replaced overfill prevention • § 281.30(c)—add notification for ownership changes • §§ 281.31 and 281.33(b)—delete upgrading requirements and eliminate phase-in schedule; add phase-in schedule for airport hydrant fuel distribution systems and UST systems with field-constructed tanks • § 281.32(c)—add requirement for states to include provisions for demonstrating compatibility with new and innovative regulated substances or other regulated substances identified by implementing agencies or include other provisions determined by the implementing agency to be no less protective of human health and the environment than the provisions for demonstrating compatibility • §§ 281.32(e) and (f) and 281.33(a)(3)— add periodic testing or inspection of spill and overfill prevention equipment, containment sumps used for interstitial monitoring of piping, and mechanical and electronic release detection components; and operation and maintenance walkthrough inspections, as well as maintaining associated records • § 281.33(c)—limit use of monthly inventory control in combination with tank tightness testing conducted every five years for the first ten years after the tank is installed or upgraded, if the tank was installed prior to a state receiving SPA • § 281.33(e)—require hazardous substance USTs to only use secondary containment with interstitial monitoring • § 281.34(a)(1)—add interstitial space may have been compromised to suspected releases • § 281.37—eliminate phase-in requirement for financial responsibility • § 281.39—require operator training according to § 9010 of the Solid Waste Disposal Act • § 281.41(a)(4)—add authority to prohibit deliveries EPA is making these technical changes to the SPA regulation. • § 281.10—change subpart to part • §§ 281.11(c), 281.20(d), 281.21(a)(2), 281.23, 281.50(a), and formerly § 281.51—eliminate interim approval • § 281.12(a)(2)—change Indian lands to Indian country • Formerly § 281.32(e)—eliminate requirement to maintain upgrade records • Formerly § 281.38—eliminate reserved section for financial VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 • • • • responsibility for USTs containing hazardous substances Move § 281.39 to § 281.38—Lender Liability §§ 281.50(e) and 281.51(c)(1)—clarify how to provide public notice to attract statewide attention § 281.51, formerly § 281.52—add requirement for approved states to submit a revised application within three years of 40 CFR part 281 changes that require a program revision § 281.61—move § 281.60(b) to § 281.61(b)(2) Background Information The 1988 SPA regulation in 40 CFR part 281 sets criteria state UST programs must meet to receive EPA’s approval to operate in lieu of the federal UST program. The 1988 SPA regulation sets performance criteria states must meet to be considered no less stringent than the federal UST regulation (hereafter 40 CFR part 280) and provides requirements for states to have adequate enforcement. It also details the components of a SPA application. EPA is changing the 1988 SPA regulation and making it consistent with this final UST regulation. By doing so, EPA will require states to adopt requirements similar to the final UST regulation, in order to obtain or retain SPA. Commenters supported maintaining the general format of the 1988 SPA regulation and EPA is keeping that general format. We are not making this final SPA regulation as explicit or prescriptive as this final UST regulation. Finally, EPA is making technical corrections and adding a deadline for states to apply for revised state program approval. Addressing Energy Policy Act Requirements and 40 CFR Part 280 Changes How SPA Works This final UST regulation primarily impacts the 1988 SPA regulation in 40 CFR part 281, subpart C—Criteria for No Less Stringent. As of 2014, 40 states, including the District of Columbia and Puerto Rico, have state program approval and state UST requirements apply in lieu of the federal requirements. To ensure these jurisdictions and any other states or territories obtaining SPA adopt these 40 CFR part 280 changes, EPA must update the 1988 SPA regulations in 40 CFR part 281, subpart C—Criteria for No Less Stringent. To continue providing states with flexibility and not disrupt current state programs, EPA is revising the 1988 SPA regulation to make it consistent PO 00000 Frm 00052 Fmt 4701 Sfmt 4700 with, but not identical to, the 40 CFR part 280 changes. Instead, EPA is making changes to the 1988 SPA regulation in a less prescriptive manner than the changes to 40 CFR part 280. Since 1988, this approach has proven a successful way to implement the UST program and provide environmental protection. The 1988 SPA regulation developed no less stringent criteria in the form of objectives.120 EPA is continuing this format so that, taken as a whole, state programs will be no less stringent than the federal requirements, even though state programs may deviate slightly from what is explicitly required in 40 CFR part 280. For example, § 281.30 covers the no less stringent requirement for new UST system design, construction, and installation; it corresponds to § 280.20 of this final UST regulation, but is much less explicit about requirements. According to § 281.30 and in order to receive SPA, a state must require all new UST systems ‘‘. . . [b]e designed, constructed, and installed in a manner that will prevent releases for their operating life due to manufacturing defects, structural failure, or corrosion . . .’’. In contrast, § 280.20 is much more explicit about how tank owners and operators ensure their tanks and piping prevent releases. It states what is required to prevent releases and provides codes of practice to comply. Although § 281.30 is less explicit, it nonetheless ensures owners and operators in approved states install UST systems that prevent releases and provides states flexibility in achieving that goal. Goal Oriented Changes EPA is making goal oriented changes to subpart C—Criteria for No Less Stringent. By the term goal oriented changes, EPA means changes in which states have some flexibility as to how they meet the goals of particular sections of the final SPA regulation. These changes reflect certain 40 CFR part 280 changes. • § 281.30(c)—add notification for ownership changes • §§ 281.31 and 281.33(b)—add a phasein schedule for upgrading previously deferred airport hydrant fuel distribution systems and UST systems with field-constructed tanks • § 281.32(c)—add requirement for states to include provisions for demonstrating compatibility with new and innovative regulated substances or other regulated substances identified by implementing agencies 120 53 E:\FR\FM\15JYR2.SGM FR 37216, September 23, 1988. 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations or include other provisions determined by the implementing agency to be no less protective of human health and the environment than the provisions for demonstrating compatibility • §§ 281.32(e) and (f) and 281.33(a)(3)— add periodic testing or inspection of spill and overfill prevention equipment, containment sumps used for interstitial monitoring of piping, and mechanical and electronic release detection components; and operation and maintenance walkthrough inspections, as well as maintaining associated records The ownership change notification in § 280.22 requires anyone who assumes ownership of an UST system to notify the implementing agency within 30 days of assuming ownership and specifies what notification must include. However, the SPA regulation change in § 281.30(c) is much less prescriptive and indicates that states require owners and operators to ‘‘. . . notify the implementing state agency within a reasonable time frame when assuming ownership of an UST system.’’ This provides states some flexibility in complying, including allowing them to continue relying on an annual tank registration program to meet this requirement. This is a reasonable way to ensure states know who owns USTs in their jurisdictions. EPA does not have an annual UST registration program, so we specify a time frame in § 280.22 because we want to know who owns tanks in jurisdictions where we are the implementing agency. EPA is requiring that previously deferred airport hydrant fuel distribution systems and UST systems with field-constructed tanks meet specific upgrade requirements in subpart K. This is one way that states can achieve compliance with § 281.31, which requires states ensure tanks are upgraded to prevent releases due to corrosion, spills, and overfills or be permanently closed. EPA concludes these more general requirements are sufficient for a state program to protect human health and the environment because they require UST systems to ‘‘. . . prevent releases for their operating life. . . .’’ EPA thinks it is also adequate to upgrade previously deferred systems to this standard. Additionally, EPA is requiring airport hydrant systems, field-constructed tanks, and emergency generator tanks be upgraded within three years of the effective date of the state requirements. For states which did not defer these systems or already had their requirements in place before the VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 effective date of this final SPA regulation, the three year requirement does not apply. In the past, EPA experienced issues with requiring states to have a particular requirement by a certain date in order to receive SPA. States applying for SPA after a deadline passed often had difficulty implementing or obtaining a retroactive requirement. EPA understands that states may have given owners and operators of UST systems previously deferred by EPA different time periods than three years to initially meet their requirements. In § 281.32(c), EPA is adding a requirement for states to include provisions for demonstrating compatibility with new and innovative regulated substances or other regulated substances identified by implementing agencies or include other provisions determined by the implementing agency to be no less protective of human health and the environment than the provisions for demonstrating compatibility. EPA is concerned about the compatibility of new and innovative fuels with the existing UST system infrastructure. We added to § 280.32 methods for demonstrating compatibility of UST systems with certain ethanol and biodiesel blends in response to this concern. State UST implementing agencies also need to ensure owners and operators only store regulated substances compatible with their UST systems. Requiring states have provisions in place for storing new and innovative regulated substances in order to receive SPA ensures states are taking appropriate steps to ensure compatibility of the UST system with a rapidly expanding spectrum of traditional and new and innovative fuels. This final UST regulation adds various UST operation and maintenance requirements. In 40 CFR part 280, EPA is requiring specific frequencies and procedures for testing or inspecting spill and overfill prevention equipment, testing containment sumps used for interstitial monitoring of piping, testing release detection equipment, and conducting operation and maintenance walkthrough inspections. According to § 281.32, states must require these tests or inspections in a manner and frequency that ensures proper functionality of equipment, includes proper operation and maintenance of the UST system, and prevents releases for the life of the equipment and UST system. EPA thinks this approach allows states that implement these requirements despite different frequencies or manners, to receive SPA, as long as their requirements PO 00000 Frm 00053 Fmt 4701 Sfmt 4700 41617 sufficiently ensure properly functioning non-releasing UST systems. EPA is updating § 281.32(g) by adding these activities to the recordkeeping requirements of SPA. Energy Policy Act Changes In this final SPA regulation, EPA is addressing Energy Policy Act requirements more generally than in this final UST regulation; however, the Energy Policy Act requirements are slightly different than the goal oriented approach discussed above. The Energy Policy Act amends the Solid Waste Disposal Act and requires states, which receive federal Subtitle I money, to adopt operator training requirements, delivery prohibition, and additional measures to protect groundwater from contamination. In the additional measures to protect groundwater provision, states must require either secondary containment and interstitial monitoring for new or replaced tanks and piping within 1,000 feet of a potable drinking water well or community water system, or manufacturer and installer financial responsibility and installer certification. The secondary containment requirement includes under-dispenser containment on any new motor fuel dispenser system within 1,000 feet of a potable drinking water well or community water system. EPA developed guidelines for states to implement the Energy Policy Act requirements; many states implemented the Energy Policy Act requirements according to these guidelines. In order to impose similar requirements in Indian country and in states that do not adopt Energy Policy Act requirements, EPA is adding secondary containment and operator training to these 40 CFR part 280 requirements. However, it is not EPA’s intent to supersede programs states developed to meet Energy Policy Act requirements. Several commenters had concerns about the Energy Policy Act provisions. Seven commenters wanted to ensure states only have to meet Energy Policy Act grant guidelines and do not have to change their regulations to mirror the 40 CFR part 280 requirements in order to obtain SPA. These commenters were also concerned that EPA requirements for secondary containment and operator training could be considered more stringent than state requirements that met the grant guidelines. EPA agrees that requiring states to alter newly implemented provisions could cause unnecessary work for states and UST owners. Therefore, this final SPA regulation explicitly addresses the secondary containment, manufacturer and installer financial responsibility E:\FR\FM\15JYR2.SGM 15JYR2 41618 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 and installer certification, delivery prohibition, and operator training requirements that appear in the Energy Policy Act. EPA agrees that it is not necessary for states already meeting these Energy Policy Act requirements to change their programs in order to receive or retain SPA. EPA was unable to incorporate a similar requirement in 40 CFR part 280, so states will need to obtain SPA in order to ensure there is no difference between state and federal requirements with respect to Energy Policy Act requirements. EPA is adding definitional exceptions in § 281.12(b). This final SPA regulation allows states to use definitions associated with tank and piping secondary containment and operator training that are different than those in 40 CFR part 280 as long as those definitions are consistent with definitions described in sections 9003 and 9010 of the Solid Waste Disposal Act. This change provides states with additional flexibility in defining key terms. EPA is adding additional measures to protect groundwater and is adding operator training requirements in subpart C (§§ 281.22(d)(3), 281.30(a), 281.33(c)(2), and 281.39). Delivery prohibition is in subpart D—Adequate Enforcement of Compliance (§ 281.40(a)). Because delivery prohibition is an enforcement option, EPA is requiring states have authority to prohibit deliveries according to the Energy Policy Act and EPA’s grant guidelines, rather than make this a no less stringent requirement. EPA is not adding delivery prohibition to 40 CFR part 280 because delivery prohibition is primarily an enforcement option for implementing agencies; it is not a requirement for owners and operators. Because the Energy Policy Act gives EPA clear delivery prohibition enforcement authority, we do not need to add delivery prohibition to this final UST regulation. However, the only way to ensure states have that same authority is to require states implement delivery prohibition as a prerequisite for SPA, as required in § 281.40(a). Specific Changes EPA is making the changes listed below to subpart C—Criteria for No Less Stringent to reflect changes made in 40 CFR part 280. These changes ensure states adopt the changes made in 40 CFR part 280 and are able to receive SPA. • §§ 281.30(a)(1) and 281.33(d)(3)— exclude safe suction piping, airport hydrant system piping, and fieldconstructed tank piping from being VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 • • • • • • required to meet the secondary containment and interstitial monitoring requirements § 281.30(b)—eliminate flow restrictors for new or replaced overfill prevention § 281.31—delete upgrading requirements § 281.33(c)—limit use of monthly inventory control in combination with tank tightness testing conducted every five years for the first ten years after the tank is installed or upgraded, if the tank was installed prior to a state receiving SPA § 281.33(e)—require hazardous substance USTs to only use secondary containment with interstitial monitoring § 281.34(a)(1)—add ‘‘. . . interstitial space may have been compromised . . .’’ to suspected releases § 281.37—eliminate phase-in requirement for financial responsibility In §§ 281.30(a)(1) and 281.33(d)(3) EPA is not requiring safe suction piping, airport hydrant system piping, and piping associated with field-constructed tanks greater than 50,000 gallons in capacity to meet the secondary containment and interstitial monitoring requirements. Suction piping that meets the requirements of § 281.33(d)(2)(ii) has characteristics that ensure little, if any, regulated substances will be released if a break occurs in the line. For additional information see section A–2, Secondary Containment. EPA is not requiring secondary containment for piping associated with field-constructed tanks greater than 50,000 gallons in capacity and airport hydrant system piping due to sloping and corrosion concerns. For additional information, see section C–2, Airport Hydrant Fuel Distribution Systems and UST Systems with FieldConstructed Tanks. In § 281.30(b), EPA is requiring states, which receive SPA, not allow installation of flow restrictors (commonly referred to as ball floats) in vent lines for overfill prevention for new installations or when flow restrictors need to be replaced. The existing goal of § 281.30(b) is for states to require that UST systems have equipment to prevent spills and overfills. In this final UST regulation, EPA maintains the overall goal to prevent spills and overfills; however, owners and operators can no longer install ball floats to achieve that goal. The deadlines for upgrades and for owners and operators to obtain financial responsibility have passed. As a result, EPA is deleting the 1988 UST regulation deadlines in the final SPA regulation. In PO 00000 Frm 00054 Fmt 4701 Sfmt 4700 §§ 281.31 and 281.33(b), EPA is removing the option for UST upgrades, except for USTs deferred in the 1988 UST regulation. In § 281.37, we are eliminating the financial responsibility phase-in schedule. Please note EPA is allowing states to implement UST requirements, such as upgrades and operation and maintenance, after the deadlines in 40 CFR part 280. EPA is taking this action because experience has shown that some states had difficulties implementing a retroactive requirement when applying for SPA after a federal deadline has passed. In § 281.33(c), EPA is allowing monthly inventory control in combination with tank tightness testing conducted every five years as a release detection method for the first ten years after a tank is installed or upgraded, only if a tank was installed prior to a state receiving SPA for the 1988 UST regulation. This reflects a change in 40 CFR part 280 and avoids another problem in the 1988 SPA regulation. First, EPA is eliminating this method for new installations. Second, EPA is tying the date for eliminating this method to the effective date of a state’s regulations. EPA concludes it is better to tie deadlines in the final SPA regulation to the effective date of states’ regulations, rather than dictate specific dates for all states. In the 2011 proposed SPA regulation, we tied the deadlines to the date a state submitted its SPA application or revised application. However, in this final SPA regulation, we realize tying the deadlines to the effective date of a state’s regulations is clearer for state regulators as well as owners and operators. Several commenters were concerned with how release detection requirements were expressed in 40 CFR part 281. One commenter was concerned that the term monthly in § 281.33(c)(1) is not as stringent as the 40 CFR part 280 requirement of completing release detection every 30 days. This commenter wanted EPA to amend the 40 CFR part 281 language so it matches the 30 day wording in 40 CFR part 280. EPA is maintaining the term monthly in 40 CFR part 281. EPA agrees there is variation between the 30 day time frame in 40 CFR part 280 and monthly in 40 CFR part 281. For states receiving SPA, the difference should result in a variation of only a few days, and therefore need not be changed. It is EPA’s position that release detection monitoring should be conducted on a consistent and frequently occurring basis. EPA chose the 30 day period in 40 CFR part 280 to represent an average calendar month. E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 In this final SPA regulation, EPA is requiring states, which wish to receive SPA, no longer allow installation of non-secondarily contained hazardous substance UST systems. This is consistent with EPA’s change in § 280.42(e); an equivalent and specific change in the final SPA regulation is the only way to ensure states adopt it. For consistency with changes in this final UST regulation and to ensure states wishing to receive SPA adopt this change, in § 281.34(a)(1), EPA is adding ‘‘. . . interstitial space may have been compromised . . .’’ to suspected release conditions. One commenter expressed concern with the release detection language in § 280.41(b)(2)(ii), which indicates EPA intends to exempt from release detection requirements suction piping that meets the condition of paragraphs (b)(1)(ii)(A) through (E). However § 281.33(d)(3) indicates that in order to be considered no less stringent, states must require new or replaced piping use interstitial monitoring with secondary containment. EPA agrees with the commenter that we need to modify § 281.33(d)(3) to incorporate the concepts of § 280.41(b)(2)(ii). In the final SPA regulation, EPA is modifying § 281.33(d)(3) to indicate that the requirement is applicable to all pressurized piping and suction piping that does not meet standards in § 281.33(d)(2)(ii). One commenter said that it may be very difficult to achieve compliance with release detection requirements for emergency power generator USTs within one year. This commenter suggested that EPA reword § 281.33(b)(3) to give owners at least three years from the effective date of the final SPA regulation. EPA agrees with the commenter and is extending the date of compliance for this requirement to three years as we are in this final UST regulation; this approach corresponds with EPA’s goal of aligning dates of compliance to the extent possible. Addressing SPA Revision Process EPA is adding a requirement for approved states to submit a revised application within three years of final SPA regulation changes that require a program revision under § 281.51. Approved states are required to revise their programs and submit revised applications whenever the federal program changes or EPA’s Administrator requests a revised application based on changes to a state’s program. Given these significant changes, EPA thinks it is necessary to develop a time frame which will ensure approved states meet final SPA VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 regulation changes in a reasonable time. EPA’s language in § 281.51 is intended only to require a state program revision within three years if EPA makes changes that necessitate state program changes. For instance, these changes to subpart C—Criteria for No Less Stringent will require state program revision. Commenters disagreed on the appropriate time frame for states to submit their SPA applications. Some said three years was appropriate, while others preferred a different time frame. EPA maintains that three years is adequate for most states to re-apply for SPA. One commenter expressed concern about what will happen to a state’s SPA status if it does not re-apply within the required time frame. While most states will be able to meet the three-year deadline for program revision, EPA is aware that some states may need additional time. EPA will work with states which have not revised their programs within three years. EPA will ask those states to demonstrate their level of effort, show progress to date, and provide dates when they will achieve major milestones for revising their programs and submitting revised applications. EPA will consider these factors before initiating state program approval withdrawal. One commenter was concerned about the cost to states of revising and reapplying for SPA. It is important for states to reapply for SPA to ensure they make appropriate changes to their programs. Additional Changes to SPA Regulation EPA is making these additional changes; they are not a direct result of these 40 CFR part 280 changes. Rather, the majority are corrections to the 1988 SPA regulation. • § 281.10—change subpart to part • §§ 281.11(c), 281.20(d), 281.21(a)(2), 281.23, and formerly § 281.51— eliminate interim approval • § 281.12(a)(2)—change Indian lands to Indian country • § 281.32(e)—eliminate requirement to maintain upgrade records • Formerly § 281.38—eliminate reserved section for financial responsibility for USTs containing hazardous substances • Move § 281.39 to § 281.38—Lender Liability • §§ 281.50(e) and 281.51(c)(1)—clarify how to provide public notice to attract statewide attention • § 281.61—move § 281.60(b) to § 281.61(b)(2) The 1988 SPA regulation incorrectly uses the term subpart in § 280.10 and, therefore, EPA is correctly changing this to part. EPA has been using the term PO 00000 Frm 00055 Fmt 4701 Sfmt 4700 41619 Indian country instead of Indian lands for years. We are now incorporating this term in this final SPA regulation; this does not alter the meaning. EPA is removing the reserved financial responsibility for USTs containing hazardous substances section (formerly § 281.38); moving the lender liability section from § 281.39 to § 281.38; and including the new operator training section in § 281.39. Because operator training needs to be in subpart C, which has no section numbers available, this eliminates the need to renumber subpart D. Also, the reserved financial responsibility for hazardous substances section is unnecessary since there is no corresponding requirement in 40 CFR part 280. EPA is deleting the interim SPA approval language in §§ 281.11(c) and 281.51. In more than 20 years of the UST program, no state applied for interim approval; it is more beneficial to receive full approval all at once, rather than in steps. Also, because 40 states, including the District of Columbia and Puerto Rico, have SPA as of 2014, EPA thinks interim SPA approval is unnecessary at this time. EPA is eliminating the requirement to maintain upgrade records for the operational life of an UST facility. This requirement in § 281.32(e) of the 1988 SPA regulation does not exist in 40 CFR part 280. In addition, except for airport hydrant systems and field-constructed tanks, EPA is no longer allowing upgrades. EPA is clarifying how to provide public notice to attract statewide attention in §§ 281.50(e) and 281.51(c)(1). In today’s digital age, it is unnecessary to require publication in a state’s newspapers. Each state can determine the most appropriate methods for public notice and statewide attention. EPA is also moving § 281.60(b) to § 281.61(b). This paragraph explains the procedure EPA will follow to withdraw approval after the conclusion of the proceeding to withdraw approval. EPA thinks this paragraph is better suited for § 281.61, which explains the procedures for withdrawing approval, as opposed to § 281.60, which explains the criteria for withdrawal. VI. Overview of Estimated Costs and Benefits EPA prepared an analysis of the potential incremental costs and benefits associated with this final UST regulation. This analysis is contained in the regulatory impact analysis document titled Assessment of the Potential Costs, Benefits, and Other Impacts of the Final Revisions to EPA’s E:\FR\FM\15JYR2.SGM 15JYR2 41620 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations Underground Storage Tank Regulations, which is available in the docket for this action. The RIA estimated regulatory implementation and compliance costs, as well as benefits for the three regulatory options described in section IV, subsection F. In the RIA, EPA estimated regulatory compliance costs on an annualized basis for the three options: $160 million (Selected Option), $290 million (Option 1), and $70 million (Option 2). Separately, the analysis assessed the potential benefits of the final UST regulation. As discussed in the RIA, a substantial portion of the beneficial impacts associated with the final UST regulation are avoided cleanup costs as a result of preventing releases and reducing the severity of releases. This action is expected to have annual cost savings related to avoided costs of $310 million (range: $120–$530 million) per year under the Selected Option, $450 million (range: $210–$670 million) per year under Option 1, and $230 million (range: $45–$420 million) per year under Option 2. Due to data and resource constraints, EPA was unable to quantify some of the final UST regulation’s benefits, including avoidance of human health risks, ecological benefits, and mitigation of acute exposure events and large-scale releases, such as those from airport hydrant systems and field-constructed tanks. EPA was also unable to place a monetary value on the groundwater protected by the final UST regulation, but estimates that this final UST regulation could potentially protect 50 billion to 240 billion gallons of groundwater each year. VII. Statutory and Executive Orders tkelley on DSK3SPTVN1PROD with RULES2 A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review Under section 3(f)(1) of Executive Order (EO) 12866 (58 FR 51735, October 4, 1993), this action is an economically significant regulatory action because it is likely to have an annual effect on the economy of $100 million or more. Accordingly, EPA submitted this action to the Office of Management and Budget (OMB) for review under EO 12866 and EO 13563 (76 FR 3821, January 21, 2011) and any changes made in response to OMB recommendations are documented in the docket for this action. Also, as part of EO 13563, EPA encourages owners and operators to maintain records electronically which simplifies compliance and VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 recordkeeping by using 21st century technology tools.121 B. Paperwork Reduction Act The information collection requirements (ICR) in this rule will be submitted for approval to the Office of Management and Budget (OMB) under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. The information collection requirements are not enforceable until OMB approves them. The proposed rule ICR was submitted to OMB on 11/18/2011 under OMB number 2050–0068, ICR number 1360.11. On 1/30/2012 OMB released a Notice of Action of comment filed on proposed rule and continue. They also issued this comment: ‘‘Terms of the previous clearance remain in effect. OMB is withholding approval at this time. Prior to publication of the final rule, the agency should provide a summary of any comments related to the information collection and their response, including any changes made to the ICR as a result of comments. In addition, the agency must enter the correct burden estimates. This action has no effect on any current approvals.’’ The final rule ICR will be submitted to OMB under a new ICR OMB control number. This action contains mandatory information collection requirements. The labor burden and associated costs for these requirements are estimated in the ICR supporting statement for this final action. The supporting statement identifies and estimates the burden for each of the changes to the regulation that include recordkeeping or reporting requirements. Changes include: adding secondary containment requirements for new and replaced tanks and piping; adding operator training requirements; adding periodic operation and maintenance requirements for UST systems; regulating certain UST systems deferred in the 1988 UST regulation; adding new release prevention and detection technologies; and updating state program approval requirements to incorporate these new changes. Based on the same data and cost calculations applied in the RIA for this action, but using the burden estimations for ICRs, the ICR supporting statement estimates an average annual labor hour burden of 344,000 hours and $12 million for the final UST regulation. One time capital and hourly costs are included in these estimates based on a three year annualization period. Burden 121 Executive Order 13563, Improving Regulation and Regulatory Review, Section 3, https:// www.gpo.gov/fdsys/pkg/FR-2011-01-21/pdf/20111385.pdf. PO 00000 Frm 00056 Fmt 4701 Sfmt 4700 is defined at 5 CFR 1320.3(b). The total universe of respondents for this ICR is comprised of 211,154 facilities and 56 states and territories. Burden is defined at 5 CFR 1320.3(b). An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA’s regulations are listed in 40 CFR part 9. When this ICR is approved by OMB, the agency will publish a technical amendment to 40 CFR part 9 in the Federal Register to display the OMB control number for the approved information collection requirements contained in this final rule. C. Regulatory Flexibility Act The Regulatory Flexibility Act generally requires an agency to prepare a regulatory flexibility analysis of any regulation subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute, unless the agency certifies that the regulation will not have a significant economic impact on a substantial number of small entities. Small entities include small businesses, small organizations, and small governmental jurisdictions. For purposes of assessing the impacts of this final UST regulation on small entities, a small entity is defined as: (1) A small business as defined by the Small Business Administration’s regulations at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city, county, town, school district, or special district with a population of less than 50,000; and (3) a small organization that is any not-forprofit enterprise which is independently owned and operated and is not dominant in its field. After considering the economic impacts of this final rule on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. The small entities directly regulated by this final rule are small businesses and small governmental jurisdictions. We have determined that less than 1 percent of potentially affected small firms in the retail motor fuel sector (NAICS 447) will experience an impact over 1 percent of revenues, but less than 3 percent of revenues. No small firms have impacts above 3 percent of revenues. In addition, we estimate that no small governmental jurisdictions will be impacted at 1 percent or 3 percent of revenues. This certification is based on the small entities analysis contained in the RIA for this final rule. E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 Although this final rule will not have a significant economic impact on a substantial number of small entities, EPA nonetheless sought to reduce the impact of this rule on small entities. EPA conducted extensive outreach to determine how to change the 1988 UST regulation. EPA worked with representatives of owners and operators and reached out specifically to small businesses. In addition, EPA limited changes that would have required major retrofits to UST systems, since this would place a high financial burden on small businesses. Finally, EPA provided numerous options for compliance in order to provide as much flexibility as possible for small entities. EPA also aligned compliance dates to facilitate owner and operator compliance. D. Unfunded Mandates Reform Act Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 1531–1538, requires federal agencies, unless otherwise prohibited by law, to assess the effects of their regulatory actions on state, local, and tribal governments and the private sector. This rule contains a federal mandate that may result in expenditures of $100 million or more for state, local, and tribal governments, in the aggregate, or the private sector in any one year. Accordingly, EPA prepared under section 202 of the UMRA a written statement which is summarized below. As estimated in the RIA, on an annualized basis, the total estimated regulatory compliance costs for the three options in this final action are $160 million (Selected Option), $290 million (Option 1), and $70 million (Option 2). Of this amount, annualized costs to state and local governments total $6.8 million under the Selected Option, $14 million under Option 1, and $3.6 million under Option 2. These costs consist of estimated regulatory compliance costs for state and local governments that currently own or operate UST systems and annualized costs of $120,000 for states to implement the final UST regulation. EPA estimates total annualized costs to owners and operators of tribally-owned UST systems are $0.67 million under the Selected Option. The estimated annualized cost to the private sector is approximately $130 million under the Selected Option, $270 million under Option 1, and $67 million under Option 2. While this final UST regulation may result in expenditures of $100 million or more for the private sector, thereby triggering section 202 of the UMRA, this final UST regulation is not subject to the requirements of section 204 of UMRA because EPA does not think state, local, VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 and tribal governments will incur aggregate costs of over $100 million per year. Consistent with section 205, EPA identified and considered a reasonable number of regulatory alternatives. This final UST regulation identifies the regulatory options EPA considered. The RIA estimates the annual cost across the three considered options may range between $70 million and $290 million. Section 205 of the UMRA requires federal agencies to select the least costly or most cost-effective regulatory alternative unless EPA publishes with the final regulation an explanation of why such alternative was not adopted. As discussed earlier in the preamble, EPA considered and evaluated variations of a subset of the regulatory requirements using two alternative options (Options 1 and 2). Despite Option 2’s lower costs, EPA chose the Selected Option because it provides for greater protection of human health and the environment and better addresses stakeholder concerns. This rule is not subject to the requirements of section 203 of UMRA because it contains no regulatory requirements that might significantly or uniquely affect small governments. E. Executive Order 13132: Federalism This action does not have federalism implications. It will not have substantial direct effects on states, the relationship between the federal government and states, or the distribution of power and responsibilities among various levels of government, as specified in EO 13132. Under this final action, total costs to all affected states and local governments (including direct compliance costs, notification costs, and state program costs) are approximately $9 million. This is not considered to be a substantial compliance cost under federalism requirements. Thus, Executive Order 13132 does not apply to this action. In the spirit of Executive Order 13132, and consistent with EPA policy to promote communications between EPA and State and local governments, EPA specifically solicited comment on the proposed action from State and local officials. F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments Subject to Executive Order 13175 (65 FR 67249, November 9, 2000) EPA may not issue a regulation that has tribal implications, that imposes substantial direct compliance costs, and that is not required by statute, unless the Federal government provides the money PO 00000 Frm 00057 Fmt 4701 Sfmt 4700 41621 necessary to pay the direct compliance costs incurred by tribal governments, or EPA consults with tribal officials early in the process of developing the proposed regulation and develops a tribal summary impact statement. EPA has concluded that this action will have tribal implications to the extent that tribally-owned entities with UST systems in Indian country will be affected. However, it will neither impose substantial direct compliance costs on tribal governments, nor preempt tribal law. EPA estimated total annualized costs for tribally-owned UST systems in Indian country to be $0.67 million. EPA consulted with tribal officials early in the process of developing this regulation to permit them to have meaningful and timely input to its development. EPA consulted with tribes on possible changes to the UST regulation shortly after the passage of the Energy Policy Act of 2005. The Energy Policy Act directed EPA to coordinate with tribes in developing and implementing an UST program strategy in Indian country which would supplement the existing approach. EPA and tribes worked collaboratively to develop a tribal strategy. There are certain key provisions of the Energy Policy Act that apply to states receiving federal Subtitle I money, but do not apply in Indian country. Nonetheless, EPA’s goal in this final UST regulation is to establish in Indian country federal requirements similar to the Energy Policy Act provisions; this is an important step in achieving more consistent program results in release prevention. Both EPA and tribes recognize the importance of ensuring parity in program implementation between states and in Indian country. In addition to early consultation with tribes, EPA also reached out to tribes as we started the official rulemaking process and while developing the 2011 proposed UST regulation. EPA sent letters to leaders of over 500 tribes, as well as to tribal regulatory staff, inviting their participation in developing the 2011 proposed UST regulation. EPA also held conference calls for tribes to provide input. EPA heard from both tribal officials who work as regulators as well as representatives of owners and operators of UST systems in Indian country. The tribal regulators raised concerns about ensuring parity of environmental protection between states and Indian country. EPA determined that this final UST regulation is needed to ensure parity between UST systems in states and in Indian country. This final UST regulation is also needed to ensure E:\FR\FM\15JYR2.SGM 15JYR2 41622 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 equipment is both installed and working properly, which will protect the environment from potential releases. As required by section 7(a), EPA’s Tribal Consultation Official certified that the requirements of the Executive Order have been met in a meaningful and timely manner. EPA included a copy of the certification in the docket for this action. G. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks This action is not subject to EO 13045 (62 FR 19885, April 23, 1997) because the Agency does not think the environmental health risks or safety risks addressed by this action present a disproportionate risk to children. EPA’s risk assessment for this action examines potential impacts to groundwater and subsequent chemical transport, exposure, and risk. While the risk assessment did not specifically measure exposure to children, the general exposure scenarios reflect four exposure pathways that have the most significant potential for human health impacts. They are: • Ingestion of chemicals in groundwater that have migrated from the source area to residential drinking water wells; • Inhalation of volatile chemicals when showering with contaminated groundwater; • Dermal contact with chemicals while bathing or showering with contaminated groundwater; and • Inhalation of vapors that may migrate upward from contaminated groundwater into overlying buildings. Adults and children can potentially be exposed through all four exposure pathways considered. For adults, inhalation of vapors while showering is the most significant exposure pathway; for children, ingestion is the most significant pathway, because they are assumed to take baths and are, therefore, not exposed via shower vapor inhalation. As a result of the longer exposure from showering, adults are more sensitive receptors for cancer effects compared to children, particularly those under age 5 who are assumed to take more baths and fewer showers.122 While the screening level risk assessment is limited in that it only examines benzene impacts, the final UST regulation will likely reduce other contaminant exposures to children in a 122 United States Department of Health and Human Services, Public Health Service, Agency for Toxic Substances and Disease Registry, Toxicological Profile For Polycyclic Aromatic Hydrocarbons, August 1995. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 similar pattern and will not create significant adverse impacts on children’s health. The screening level population analysis performed to examine EO 12898 shows that children under 18 years and children under 5 years of age are slightly less likely to be found in the vicinity of UST facilities. This suggests that the impacts of this action will not have a disproportionate impact on children’s health. Moreover, because all regulatory options in this action will increase regulatory stringency and reduce the number and size of releases, EPA does not expect this action to have any disproportionate adverse impact on children. H. Executive Order 13211: Actions Concerning Regulations that Significantly Affect Energy Supply, Distribution, or Use This action is not a significant energy action as defined in Executive Order 13211 (66 FR 28355, May 22, 2001), because it is not likely to have a significant adverse effect on the supply, distribution, or use of energy. The following summarizes EPA’s assessment of the energy impacts this final UST regulation will have on energy supply, distribution, and use. This final UST regulation consists of additional regulatory requirements that apply to the owners and operators of underground storage tanks. To the extent that the final UST regulation affects the motor fuel sector, it does so at the retail motor fuel sales level, rather than the level of refineries or distributors, who supply the retail stations with motor fuel. Therefore, we do not expect this final UST regulation to have a significant adverse impact on energy supply or distribution. The additional regulatory requirements contained in this final UST regulation may increase compliance costs for owners and operators of retail motor fuel stations. If owners and operators of retail motor fuel stations affected by the final UST regulation can pass through their increased compliance costs, energy use may be affected via higher energy prices caused by the final UST regulation. However, we do not expect a significant change in retail gasoline prices to result from this final UST regulation for the following reasons: • Economic analyses of retail fuel prices revealed that demand for gasoline is highly sensitive to price (elastic) within localized geographic areas—as a result, if one motor fuel retailer in an area passes through increases in compliance costs by increasing gasoline prices, while another does not, the one PO 00000 Frm 00058 Fmt 4701 Sfmt 4700 with higher prices is at a competitive disadvantage; and • Retail motor fuel stations often have associated stores or services, such as car washes, repair operations, and convenience outlets, on which they can more successfully pass through increases in compliance costs. Furthermore, when considered in the context of total fuel consumption in the United States, this final UST regulation will represent only a very small fraction of motor fuel prices, even if fully passed through to consumers. According to the Bureau of Transportation Statistics, the United States consumed approximately 169 billion gallons of motor fuel (including gasoline and diesel) in 2011 at an average price of $3.73.123 This implies that consumers spent $629 billion in 2012 on motor fuel. The overall cost of the final UST regulation is approximately $160 million, less than 0.1 percent of the amount spent by end users on motor fuel in 2012. In comparison, an increase of 1 cent in the average price of motor fuel in 2012 would have increased the total cost to consumers by approximately $1.7 billion. Given these circumstances, this final UST regulation should not measurably impact retail motor fuel prices. As a result, EPA does not expect this final UST regulation to have a significant adverse impact on energy prices or use. I. National Technology Transfer and Advancement Act Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 104– 113 (15 U.S.C. 272 note) directs EPA to use voluntary consensus standards in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical 123 2011 is the latest year data available from Bureau of Transportation Statistics for gallons of motor fuel consumed, as reported by: U.S. Department of Transportation, Research and Innovative Technology Administration, Bureau of Transportation Statistics. Accessed at: https:// www.rita.dot.gov/bts/sites/rita.dot.gov.bts/files/ publications/national_transportation_statistics/ html/table_04_09.html. The 2012 prices per gallon for all grades of retail motor gasoline and No. 2 diesel fuel (all concentrations of sulfur) were $3.63 and $3.97, respectively, as reported by: U.S. Energy Information Administration. Short-Term Energy Outlook—Real and Nominal Energy Prices for 2012. Accessed at: https://www.eia.gov/forecasts/steo/ realprices/. We weight these prices according to prime supplier sales volumes in 2012 published by the Energy Information Administration, which summed to 347,234.5 thousands of gallons per day for gasoline and 143,270.6 thousands of gallons per day for all grades of diesel fuel (U.S. Energy Information Administration.

NTTAA directs EPA to provide Congress, through OMB, explanations when EPA decides not to use available and applicable voluntary consensus standards. This action uses technical standards. EPA has decided to use voluntary consensus standards, called codes of practice, described in section E–2. These codes of practice meet the objectives of this action by establishing criteria for the design, construction, and maintenance of underground storage tanks. J. Executive Order 12898: Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations Executive Order 12898 (59 FR 7629, Feb. 16, 1994) establishes federal executive policy on environmental justice. Its main provision directs federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental effects of their programs, policies, and activities on minority populations and low-income populations in the United States. EPA has determined that this action will not have disproportionately high and adverse human health or environmental effects on minority or low-income populations because it increases the level of environmental protection for all affected populations without having any disproportionately high and adverse human health or environmental effects on any population, including any minority or low-income population. To inform us about the socioeconomic characteristics of communities potentially affected by this final UST regulation, EPA conducted a screening analysis under the 2011 proposed UST regulation to examine whether there is a statistically significant disparity between socioeconomic characteristics of populations located near UST facilities and those that are not.124 As discussed in the RIA, the results indicate that minority and low-income populations are slightly more likely to 124 Note that the affected populations identified in the screening analysis summarized here are simply defined by specific demographics surrounding UST locations. These affected populations are not necessarily equivalent to communities that others have specifically identified as environmental justice communities. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 41623 be located near UST facilities. An environmental justice analysis would then require an assessment of whether there would be disproportionate and adverse impacts on these populations. However, because all regulatory options considered in this final UST regulation would increase regulatory stringency and reduce the number and size of releases, EPA does not anticipate the final UST regulation will have any disproportionately high and adverse human health or environmental effects on these minority or low-income communities or any community.

Unless corrective action is initiated in accordance with subpart F, owners and operators must immediately investigate and confirm all suspected releases of regulated substances requiring reporting under § 280.50 within 7 days, or another reasonable time period specified by the implementing agency, using either the following steps or another procedure approved by the implementing agency: (a) System test. Owners and operators must conduct tests (according to the requirements for tightness testing in §§ 280.43(c) and 280.44(b) or, as appropriate, secondary containment testing described in § 280.33(d)). (1) The test must determine whether: (i) A leak exists in that portion of the tank that routinely contains product, or the attached delivery piping; or (ii) A breach of either wall of the secondary containment has occurred. (2) If the system test confirms a leak into the interstice or a release, owners and operators must repair, replace, upgrade, or close the UST system. In addition, owners and operators must begin corrective action in accordance with subpart F of this part if the test results for the system, tank, or delivery piping indicate that a release exists. (3) Further investigation is not required if the test results for the system, tank, and delivery piping do not indicate that a release exists and if environmental contamination is not the basis for suspecting a release. (4) Owners and operators must conduct a site check as described in paragraph (b) of this section if the test results for the system, tank, and delivery piping do not indicate that a release exists but environmental contamination is the basis for suspecting a release. (b) Site check. Owners and operators must measure for the presence of a release where contamination is most VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 likely to be present at the UST site. In selecting sample types, sample locations, and measurement methods, owners and operators must consider the nature of the stored substance, the type of initial alarm or cause for suspicion, the type of backfill, the depth of groundwater, and other factors appropriate for identifying the presence and source of the release. (1) If the test results for the excavation zone or the UST site indicate that a release has occurred, owners and operators must begin corrective action in accordance with subpart F of this part; (2) If the test results for the excavation zone or the UST site do not indicate that a release has occurred, further investigation is not required. § 280.53 Reporting and cleanup of spills and overfills. (a) Owners and operators of UST systems must contain and immediately clean up a spill or overfill and report to the implementing agency within 24 hours, or another reasonable time period specified by the implementing agency, and begin corrective action in accordance with subpart F of this part in the following cases: (1) Spill or overfill of petroleum that results in a release to the environment that exceeds 25 gallons or another reasonable amount specified by the implementing agency, or that causes a sheen on nearby surface water; and (2) Spill or overfill of a hazardous substance that results in a release to the environment that equals or exceeds its reportable quantity under CERCLA (40 CFR part 302). Note to paragraph (a). Pursuant to §§ 302.6 and 355.40 of this chapter, a release of a hazardous substance equal to or in excess of its reportable quantity must also be reported immediately (rather than within 24 hours) to the National Response Center under sections 102 and 103 of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 and to appropriate state and local authorities under Title III of the Superfund Amendments and Reauthorization Act of 1986. (b) Owners and operators of UST systems must contain and immediately clean up a spill or overfill of petroleum that is less than 25 gallons or another reasonable amount specified by the implementing agency, and a spill or overfill of a hazardous substance that is less than the reportable quantity. If cleanup cannot be accomplished within 24 hours, or another reasonable time period established by the implementing agency, owners and operators must immediately notify the implementing agency.

If these remedies include treatment or disposal of soils, the owner and operator must comply with applicable state and local requirements; (5) Measure for the presence of a release where contamination is most E:\FR\FM\15JYR2.SGM 15JYR2 41638 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations likely to be present at the UST site, unless the presence and source of the release have been confirmed in accordance with the site check required by § 280.52(b) or the closure site assessment of § 280.72(a). In selecting sample types, sample locations, and measurement methods, the owner and operator must consider the nature of the stored substance, the type of backfill, depth to groundwater and other factors as appropriate for identifying the presence and source of the release; and (6) Investigate to determine the possible presence of free product, and begin free product removal as soon as practicable and in accordance with § 280.64. (b) Within 20 days after release confirmation, or within another reasonable period of time determined by the implementing agency, owners and operators must submit a report to the implementing agency summarizing the initial abatement steps taken under paragraph (a) of this section and any resulting information or data. tkelley on DSK3SPTVN1PROD with RULES2 § 280.63 Initial site characterization. (a) Unless directed to do otherwise by the implementing agency, owners and operators must assemble information about the site and the nature of the release, including information gained while confirming the release or completing the initial abatement measures in §§ 280.60 and 280.61. This information must include, but is not necessarily limited to the following: (1) Data on the nature and estimated quantity of release; (2) Data from available sources and/or site investigations concerning the following factors: Surrounding populations, water quality, use and approximate locations of wells potentially affected by the release, subsurface soil conditions, locations of subsurface sewers, climatological conditions, and land use; (3) Results of the site check required under § 280.62(a)(5); and (4) Results of the free product investigations required under § 280.62(a)(6), to be used by owners and operators to determine whether free product must be recovered under § 280.64. (b) Within 45 days of release confirmation or another reasonable period of time determined by the implementing agency, owners and operators must submit the information collected in compliance with paragraph (a) of this section to the implementing agency in a manner that demonstrates its applicability and technical adequacy, or in a format and according to the VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 schedule required by the implementing agency. § 280.64 Free product removal. At sites where investigations under § 280.62(a)(6) indicate the presence of free product, owners and operators must remove free product to the maximum extent practicable as determined by the implementing agency while continuing, as necessary, any actions initiated under §§ 280.61 through 280.63, or preparing for actions required under §§ 280.65 through 280.66. In meeting the requirements of this section, owners and operators must: (a) Conduct free product removal in a manner that minimizes the spread of contamination into previously uncontaminated zones by using recovery and disposal techniques appropriate to the hydrogeologic conditions at the site, and that properly treats, discharges or disposes of recovery byproducts in compliance with applicable local, state, and federal regulations; (b) Use abatement of free product migration as a minimum objective for the design of the free product removal system; (c) Handle any flammable products in a safe and competent manner to prevent fires or explosions; and (d) Unless directed to do otherwise by the implementing agency, prepare and submit to the implementing agency, within 45 days after confirming a release, a free product removal report that provides at least the following information: (1) The name of the person(s) responsible for implementing the free product removal measures; (2) The estimated quantity, type, and thickness of free product observed or measured in wells, boreholes, and excavations; (3) The type of free product recovery system used; (4) Whether any discharge will take place on-site or off-site during the recovery operation and where this discharge will be located; (5) The type of treatment applied to, and the effluent quality expected from, any discharge; (6) The steps that have been or are being taken to obtain necessary permits for any discharge; and (7) The disposition of the recovered free product. § 280.65 Investigations for soil and groundwater cleanup. (a) In order to determine the full extent and location of soils contaminated by the release and the presence and concentrations of PO 00000 Frm 00074 Fmt 4701 Sfmt 4700 dissolved product contamination in the groundwater, owners and operators must conduct investigations of the release, the release site, and the surrounding area possibly affected by the release if any of the following conditions exist: (1) There is evidence that groundwater wells have been affected by the release (e.g., as found during release confirmation or previous corrective action measures); (2) Free product is found to need recovery in compliance with § 280.64; (3) There is evidence that contaminated soils may be in contact with groundwater (e.g., as found during conduct of the initial response measures or investigations required under §§ 280.60 through 280.64); and (4) The implementing agency requests an investigation, based on the potential effects of contaminated soil or groundwater on nearby surface water and groundwater resources. (b) Owners and operators must submit the information collected under paragraph (a) of this section as soon as practicable or in accordance with a schedule established by the implementing agency. § 280.66 Corrective action plan. (a) At any point after reviewing the information submitted in compliance with §§ 280.61 through 280.63, the implementing agency may require owners and operators to submit additional information or to develop and submit a corrective action plan for responding to contaminated soils and groundwater. If a plan is required, owners and operators must submit the plan according to a schedule and format established by the implementing agency. Alternatively, owners and operators may, after fulfilling the requirements of §§ 280.61 through 280.63, choose to submit a corrective action plan for responding to contaminated soil and groundwater. In either case, owners and operators are responsible for submitting a plan that provides for adequate protection of human health and the environment as determined by the implementing agency, and must modify their plan as necessary to meet this standard. (b) The implementing agency will approve the corrective action plan only after ensuring that implementation of the plan will adequately protect human health, safety, and the environment. In making this determination, the implementing agency should consider the following factors as appropriate: (1) The physical and chemical characteristics of the regulated E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations substance, including its toxicity, persistence, and potential for migration; (2) The hydrogeologic characteristics of the facility and the surrounding area; (3) The proximity, quality, and current and future uses of nearby surface water and groundwater; (4) The potential effects of residual contamination on nearby surface water and groundwater; (5) An exposure assessment; and (6) Any information assembled in compliance with this subpart. (c) Upon approval of the corrective action plan or as directed by the implementing agency, owners and operators must implement the plan, including modifications to the plan made by the implementing agency. They must monitor, evaluate, and report the results of implementing the plan in accordance with a schedule and in a format established by the implementing agency. (d) Owners and operators may, in the interest of minimizing environmental contamination and promoting more effective cleanup, begin cleanup of soil and groundwater before the corrective action plan is approved provided that they: (1) Notify the implementing agency of their intention to begin cleanup; (2) Comply with any conditions imposed by the implementing agency, including halting cleanup or mitigating adverse consequences from cleanup activities; and (3) Incorporate these self-initiated cleanup measures in the corrective action plan that is submitted to the implementing agency for approval. tkelley on DSK3SPTVN1PROD with RULES2 § 280.67 Public participation. (a) For each confirmed release that requires a corrective action plan, the implementing agency must provide notice to the public by means designed to reach those members of the public directly affected by the release and the planned corrective action. This notice may include, but is not limited to, public notice in local newspapers, block advertisements, public service announcements, publication in a state register, letters to individual households, or personal contacts by field staff. (b) The implementing agency must ensure that site release information and decisions concerning the corrective action plan are made available to the public for inspection upon request. (c) Before approving a corrective action plan, the implementing agency may hold a public meeting to consider comments on the proposed corrective action plan if there is sufficient public interest, or for any other reason. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 (d) The implementing agency must give public notice that complies with paragraph (a) of this section if implementation of an approved corrective action plan does not achieve the established cleanup levels in the plan and termination of that plan is under consideration by the implementing agency. Subpart G—Out-of-Service UST Systems and Closure § 280.70 Temporary closure. (a) When an UST system is temporarily closed, owners and operators must continue operation and maintenance of corrosion protection in accordance with § 280.31, and any release detection in accordance with subparts D and K of this part. Subparts E and F of this part must be complied with if a release is suspected or confirmed. However, release detection and release detection operation and maintenance testing and inspections in subparts C and D of this part are not required as long as the UST system is empty. The UST system is empty when all materials have been removed using commonly employed practices so that no more than 2.5 centimeters (one inch) of residue, or 0.3 percent by weight of the total capacity of the UST system, remain in the system. In addition, spill and overfill operation and maintenance testing and inspections in subpart C of this part are not required. (b) When an UST system is temporarily closed for 3 months or more, owners and operators must also comply with the following requirements: (1) Leave vent lines open and functioning; and (2) Cap and secure all other lines, pumps, manways, and ancillary equipment. (c) When an UST system is temporarily closed for more than 12 months, owners and operators must permanently close the UST system if it does not meet either performance standards in § 280.20 for new UST systems or the upgrading requirements in § 280.21, except that the spill and overfill equipment requirements do not have to be met. Owners and operators must permanently close the substandard UST systems at the end of this 12-month period in accordance with §§ 280.71 through 280.74, unless the implementing agency provides an extension of the 12-month temporary closure period. Owners and operators must complete a site assessment in accordance with § 280.72 before such an extension can be applied for.

(a) At least 30 days before beginning either permanent closure or a change-inservice under paragraphs (b) and (c) of this section, or within another reasonable time period determined by the implementing agency, owners and operators must notify the implementing agency of their intent to permanently close or make the change-in-service, unless such action is in response to corrective action. The required assessment of the excavation zone under § 280.72 must be performed after notifying the implementing agency but before completion of the permanent closure or a change-in-service. (b) To permanently close a tank, owners and operators must empty and clean it by removing all liquids and accumulated sludges. All tanks taken out of service permanently must: be removed from the ground, filled with an inert solid material, or closed in place in a manner approved by the implementing agency. (c) Continued use of an UST system to store a non-regulated substance is considered a change-in-service. Before a change-in-service, owners and operators must empty and clean the tank by removing all liquid and accumulated sludge and conduct a site assessment in accordance with § 280.72. Note to § 280.71. The following cleaning and closure procedures may be used to comply with this section: (A) American Petroleum Institute Recommended Practice RP 1604, ‘‘Closure of Underground Petroleum Storage Tanks’’; (B) American Petroleum Institute Standard 2015, ‘‘Safe Entry and Cleaning of Petroleum Storage Tanks, Planning and Managing Tank Entry From Decommissioning Through Recommissioning’’; (C) American Petroleum Institute Recommended Practice 2016, ‘‘Guidelines and Procedures for Entering and Cleaning Petroleum Storage Tanks’’; (D) American Petroleum Institute Recommended Practice RP 1631, ‘‘Interior Lining and Periodic Inspection of Underground Storage Tanks,’’ may be used as guidance for compliance with this section; (E) National Fire Protection Association Standard 326, ‘‘Standard for the Safeguarding of Tanks and Containers for Entry, Cleaning, or Repair’’; and (F) National Institute for Occupational Safety and Health Publication 80–106, ‘‘Criteria for a Recommended Standard . . .

(a) Before permanent closure or a change-in-service is completed, owners E:\FR\FM\15JYR2.SGM 15JYR2 41640 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations and operators must measure for the presence of a release where contamination is most likely to be present at the UST site. In selecting sample types, sample locations, and measurement methods, owners and operators must consider the method of closure, the nature of the stored substance, the type of backfill, the depth to groundwater, and other factors appropriate for identifying the presence of a release. The requirements of this section are satisfied if one of the external release detection methods allowed in § 280.43(e) and (f) is operating in accordance with the requirements in § 280.43 at the time of closure, and indicates no release has occurred. (b) If contaminated soils, contaminated groundwater, or free product as a liquid or vapor is discovered under paragraph (a) of this section, or by any other manner, owners and operators must begin corrective action in accordance with subpart F of this part. § 280.73 Applicability to previously closed UST systems. When directed by the implementing agency, the owner and operator of an UST system permanently closed before December 22, 1988 must assess the excavation zone and close the UST system in accordance with this subpart if releases from the UST may, in the judgment of the implementing agency, pose a current or potential threat to human health and the environment. § 280.74 Closure records. Owners and operators must maintain records in accordance with § 280.34 that are capable of demonstrating compliance with closure requirements under this subpart. The results of the excavation zone assessment required in § 280.72 must be maintained for at least three years after completion of permanent closure or change-in-service in one of the following ways: (a) By the owners and operators who took the UST system out of service; (b) By the current owners and operators of the UST system site; or (c) By mailing these records to the implementing agency if they cannot be maintained at the closed facility. tkelley on DSK3SPTVN1PROD with RULES2 Subpart H—Financial Responsibility § 280.90 Applicability.

(c) State and Federal government entities whose debts and liabilities are the debts and liabilities of a state or the United States are exempt from the requirements of this subpart. (d) The requirements of this subpart do not apply to owners and operators of any UST system described in § 280.10(b), (c)(1), (c)(3), or (c)(4). (e) If the owner and operator of a petroleum underground storage tank are separate persons, only one person is required to demonstrate financial responsibility; however, both parties are liable in event of noncompliance. § 280.91 Compliance dates. Owners of petroleum underground storage tanks must comply with the requirements of this subpart. Previously deferred UST systems must comply with the requirements of this subpart according to the schedule in § 280.251(a). § 280.92 Definition of terms. When used in this subpart, the following terms shall have the meanings given below: Accidental release means any sudden or nonsudden release of petroleum arising from operating an underground storage tank that results in a need for corrective action and/or compensation for bodily injury or property damage neither expected nor intended by the tank owner or operator. Bodily injury shall have the meaning given to this term by applicable state law; however, this term shall not include those liabilities which, consistent with standard insurance industry practices, are excluded from coverage in liability insurance policies for bodily injury. Chief Financial Officer, in the case of local government owners and operators, means the individual with the overall authority and responsibility for the collection, disbursement, and use of funds by the local government. Controlling interest means direct ownership of at least 50 percent of the voting stock of another entity. Director of the Implementing Agency means the EPA Regional Administrator, or, in the case of a state with a program approved under section 9004, the Director of the designated state or local agency responsible for carrying out an approved UST program. Financial reporting year means the latest consecutive twelve-month period for which any of the following reports used to support a financial test is prepared: (1) A 10–K report submitted to the SEC; PO 00000 Frm 00076 Fmt 4701 Sfmt 4700 (2) An annual report of tangible net worth submitted to Dun and Bradstreet; or (3) Annual reports submitted to the Energy Information Administration or the Rural Utilities Service. Note to the definition of Financial reporting year. ‘‘Financial reporting year’’ may thus comprise a fiscal or a calendar year period. Legal defense cost is any expense that an owner or operator or provider of financial assurance incurs in defending against claims or actions brought: (1) By EPA or a state to require corrective action or to recover the costs of corrective action; (2) By or on behalf of a third party for bodily injury or property damage caused by an accidental release; or (3) By any person to enforce the terms of a financial assurance mechanism. Local government shall have the meaning given this term by applicable state law and includes Indian tribes. The term is generally intended to include: (1) Counties, municipalities, townships, separately chartered and operated special districts (including local government public transit systems and redevelopment authorities), and independent school districts authorized as governmental bodies by state charter or constitution; and (2) Special districts and independent school districts established by counties, municipalities, townships, and other general purpose governments to provide essential services. Occurrence means an accident, including continuous or repeated exposure to conditions, which results in a release from an underground storage tank. Note to the definition of Occurrence. This definition is intended to assist in the understanding of these regulations and is not intended either to limit the meaning of ‘‘occurrence’’ in a way that conflicts with standard insurance usage or to prevent the use of other standard insurance terms in place of ‘‘occurrence.’’ Owner or operator, when the owner or operator are separate parties, refers to the party that is obtaining or has obtained financial assurances. Petroleum marketing facilities include all facilities at which petroleum is produced or refined and all facilities from which petroleum is sold or transferred to other petroleum marketers or to the public. Property damage shall have the meaning given this term by applicable state law. This term shall not include those liabilities which, consistent with standard insurance industry practices, E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations tkelley on DSK3SPTVN1PROD with RULES2 are excluded from coverage in liability insurance policies for property damage. However, such exclusions for property damage shall not include corrective action associated with releases from tanks which are covered by the policy. Provider of financial assurance means an entity that provides financial assurance to an owner or operator of an underground storage tank through one of the mechanisms listed in §§ 280.95 through 280.107, including a guarantor, insurer, risk retention group, surety, issuer of a letter of credit, issuer of a state-required mechanism, or a state. Substantial business relationship means the extent of a business relationship necessary under applicable state law to make a guarantee contract issued incident to that relationship valid and enforceable. A guarantee contract is issued ‘‘incident to that relationship’’ if it arises from and depends on existing economic transactions between the guarantor and the owner or operator. Substantial governmental relationship means the extent of a governmental relationship necessary under applicable state law to make an added guarantee contract issued incident to that relationship valid and enforceable. A guarantee contract is issued ‘‘incident to that relationship’’ if it arises from a clear commonality of interest in the event of an UST release such as coterminous boundaries, overlapping constituencies, common groundwater aquifer, or other relationship other than monetary compensation that provides a motivation for the guarantor to provide a guarantee. Tangible net worth means the tangible assets that remain after deducting liabilities; such assets do not include intangibles such as goodwill and rights to patents or royalties. For purposes of this definition, ‘‘assets’’ means all existing and all probable future economic benefits obtained or controlled by a particular entity as a result of past transactions. Termination under § 280.97(b)(1) and (2) means only those changes that could result in a gap in coverage as where the insured has not obtained substitute coverage or has obtained substitute coverage with a different retroactive date than the retroactive date of the original policy. § 280.93 Amount and scope of required financial responsibility. (a) Owners or operators of petroleum underground storage tanks must demonstrate financial responsibility for taking corrective action and for compensating third parties for bodily injury and property damage caused by VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 accidental releases arising from the operation of petroleum underground storage tanks in at least the following per-occurrence amounts: (1) For owners or operators of petroleum underground storage tanks that are located at petroleum marketing facilities, or that handle an average of more than 10,000 gallons of petroleum per month based on annual throughput for the previous calendar year; $1 million. (2) For all other owners or operators of petroleum underground storage tanks; $500,000. (b) Owners or operators of petroleum underground storage tanks must demonstrate financial responsibility for taking corrective action and for compensating third parties for bodily injury and property damage caused by accidental releases arising from the operation of petroleum underground storage tanks in at least the following annual aggregate amounts: (1) For owners or operators of 1 to 100 petroleum underground storage tanks, $1 million; and (2) For owners or operators of 101 or more petroleum underground storage tanks, $2 million. (c) For the purposes of paragraphs (b) and (f) of this section, only, ‘‘a petroleum underground storage tank’’ means a single containment unit and does not mean combinations of single containment units. (d) Except as provided in paragraph (e) of this section, if the owner or operator uses separate mechanisms or separate combinations of mechanisms to demonstrate financial responsibility for: (1) Taking corrective action; (2) Compensating third parties for bodily injury and property damage caused by sudden accidental releases; or (3) Compensating third parties for bodily injury and property damage caused by nonsudden accidental releases, the amount of assurance provided by each mechanism or combination of mechanisms must be in the full amount specified in paragraphs (a) and (b) of this section. (e) If an owner or operator uses separate mechanisms or separate combinations of mechanisms to demonstrate financial responsibility for different petroleum underground storage tanks, the annual aggregate required shall be based on the number of tanks covered by each such separate mechanism or combination of mechanisms. (f) Owners or operators shall review the amount of aggregate assurance provided whenever additional petroleum underground storage tanks are acquired or installed. If the number PO 00000 Frm 00077 Fmt 4701 Sfmt 4700 41641 of petroleum underground storage tanks for which assurance must be provided exceeds 100, the owner or operator shall demonstrate financial responsibility in the amount of at least $2 million of annual aggregate assurance by the anniversary of the date on which the mechanism demonstrating financial responsibility became effective. If assurance is being demonstrated by a combination of mechanisms, the owner or operator shall demonstrate financial responsibility in the amount of at least $2 million of annual aggregate assurance by the first-occurring effective date anniversary of any one of the mechanisms combined (other than a financial test or guarantee) to provide assurance.

Evidence of such interests also includes assignments, pledges, or other rights to or other forms of encumbrance against property that are held primarily to protect a security interest. A person is not required to hold title or a security interest in order to maintain indicia of ownership. (d) A holder is a person who, upon the effective date of this regulation or in the future, maintains indicia of ownership (as defined in § 280.200(c)) primarily to protect a security interest (as defined in § 280.200(f)(1)) in a petroleum UST or UST system or facility or property on which a petroleum UST or UST system is located. A holder includes the initial holder (such as a loan originator); any subsequent holder (such as a successorin-interest or subsequent purchaser of the security interest on the secondary market); a guarantor of an obligation, surety, or any other person who holds ownership indicia primarily to protect a security interest; or a receiver or other person who acts on behalf or for the benefit of a holder.

Security interests may also arise from transactions such as sale and leasebacks, conditional sales, installment sales, trust receipt transactions, certain assignments, factoring agreements, accounts receivable financing arrangements, and consignments, if the transaction creates or establishes an interest in an UST or UST system or in the facility or property on which the UST or UST system is located, for the E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations purpose of securing a loan or other obligation. (2) Primarily to protect a security interest, as used in this subpart, does not include indicia of ownership held primarily for investment purposes, nor ownership indicia held primarily for purposes other than as protection for a security interest. A holder may have other, secondary reasons for maintaining indicia of ownership, but the primary reason why any ownership indicia are held must be as protection for a security interest. (g) Operation means, for purposes of this subpart, the use, storage, filling, or dispensing of petroleum contained in an UST or UST system. tkelley on DSK3SPTVN1PROD with RULES2 § 280.210 Participation in management. The term ‘‘participating in the management of an UST or UST system’’ means that, subsequent to the effective date of this subpart, December 6, 1995, the holder is engaging in decisionmaking control of, or activities related to, operation of the UST or UST system, as defined herein. (a) Actions that are participation in management. (1) Participation in the management of an UST or UST system means, for purposes of this subpart, actual participation by the holder in the management or control of decisionmaking related to the operation of an UST or UST system. Participation in management does not include the mere capacity or ability to influence or the unexercised right to control UST or UST system operations. A holder is participating in the management of the UST or UST system only if the holder either: (i) Exercises decisionmaking control over the operational (as opposed to financial or administrative) aspects of the UST or UST system, such that the holder has undertaken responsibility for all or substantially all of the management of the UST or UST system; or (ii) Exercises control at a level comparable to that of a manager of the borrower’s enterprise, such that the holder has assumed or manifested responsibility for the overall management of the enterprise encompassing the day-to-day decisionmaking of the enterprise with respect to all, or substantially all, of the operational (as opposed to financial or administrative) aspects of the enterprise. (2) Operational aspects of the enterprise relate to the use, storage, filling, or dispensing of petroleum contained in an UST or UST system, and include functions such as that of a facility or plant manager, operations manager, chief operating officer, or chief VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 executive officer. Financial or administrative aspects include functions such as that of a credit manager, accounts payable/receivable manager, personnel manager, controller, chief financial officer, or similar functions. Operational aspects of the enterprise do not include the financial or administrative aspects of the enterprise, or actions associated with environmental compliance, or actions undertaken voluntarily to protect the environment in accordance with applicable requirements in this part or applicable state requirements in those states that have been delegated authority by EPA to administer the UST program pursuant to 42 U.S.C. 6991c and 40 CFR part 281. (b) Actions that are not participation in management pre-foreclosure. (1) Actions at the inception of the loan or other transaction. No act or omission prior to the time that indicia of ownership are held primarily to protect a security interest constitutes evidence of participation in management within the meaning of this subpart. A prospective holder who undertakes or requires an environmental investigation (which could include a site assessment, inspection, and/or audit) of the UST or UST system or facility or property on which the UST or UST system is located (in which indicia of ownership are to be held), or requires a prospective borrower to clean up contamination from the UST or UST system or to comply or come into compliance (whether prior or subsequent to the time that indicia of ownership are held primarily to protect a security interest) with any applicable law or regulation, is not by such action considered to be participating in the management of the UST or UST system or facility or property on which the UST or UST system is located. (2) Loan policing and work out. Actions that are consistent with holding ownership indicia primarily to protect a security interest do not constitute participation in management for purposes of this subpart. The authority for the holder to take such actions may, but need not, be contained in contractual or other documents specifying requirements for financial, environmental, and other warranties, covenants, conditions, representations or promises from the borrower. Loan policing and work out activities cover and include all such activities up to foreclosure, exclusive of any activities that constitute participation in management. (i) Policing the security interest or loan. (A) A holder who engages in policing activities prior to foreclosure PO 00000 Frm 00099 Fmt 4701 Sfmt 4700 41663 will remain within the exemption provided that the holder does not together with other actions participate in the management of the UST or UST system as provided in § 280.210(a). Such policing actions include, but are not limited to, requiring the borrower to clean up contamination from the UST or UST system during the term of the security interest; requiring the borrower to comply or come into compliance with applicable federal, state, and local environmental and other laws, rules, and regulations during the term of the security interest; securing or exercising authority to monitor or inspect the UST or UST system or facility or property on which the UST or UST system is located (including on-site inspections) in which indicia of ownership are maintained, or the borrower’s business or financial condition during the term of the security interest; or taking other actions to adequately police the loan or security interest (such as requiring a borrower to comply with any warranties, covenants, conditions, representations, or promises from the borrower). (B) Policing activities also include undertaking by the holder of UST environmental compliance actions and voluntary environmental actions taken in compliance with this part, provided that the holder does not otherwise participate in the management or daily operation of the UST or UST system as provided in § 280.210(a) and § 280.230. Such allowable actions include, but are not limited to, release detection and release reporting, release response and corrective action, temporary or permanent closure of an UST or UST system, UST upgrading or replacement, and maintenance of corrosion protection. A holder who undertakes these actions must do so in compliance with the applicable requirements in this part or applicable state requirements in those states that have been delegated authority by EPA to administer the UST program pursuant to 42 U.S.C. 6991c and 40 CFR part 281. A holder may directly oversee these environmental compliance actions and voluntary environmental actions, and directly hire contractors to perform the work, and is not by such action considered to be participating in the management of the UST or UST system. (ii) Loan work out. A holder who engages in work out activities prior to foreclosure will remain within the exemption provided that the holder does not together with other actions participate in the management of the UST or UST system as provided in § 280.210(a). For purposes of this rule, ‘‘work out’’ refers to those actions by which a holder, at any time prior to E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 41664 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations foreclosure, seeks to prevent, cure, or mitigate a default by the borrower or obligor; or to preserve, or prevent the diminution of, the value of the security. Work out activities include, but are not limited to, restructuring or renegotiating the terms of the security interest; requiring payment of additional rent or interest; exercising forbearance; requiring or exercising rights pursuant to an assignment of accounts or other amounts owing to an obligor; requiring or exercising rights pursuant to an escrow agreement pertaining to amounts owing to an obligor; providing specific or general financial or other advice, suggestions, counseling, or guidance; and exercising any right or remedy the holder is entitled to by law or under any warranties, covenants, conditions, representations, or promises from the borrower. (c) Foreclosure on an UST or UST system or facility or property on which an UST or UST system is located, and participation in management activities post-foreclosure. (1) Foreclosure. (i) Indicia of ownership that are held primarily to protect a security interest include legal or equitable title or deed to real or personal property acquired through or incident to foreclosure. For purposes of this subpart, the term ‘‘foreclosure’’ means that legal, marketable or equitable title or deed has been issued, approved, and recorded, and that the holder has obtained access to the UST, UST system, UST facility, and property on which the UST or UST system is located, provided that the holder acted diligently to acquire marketable title or deed and to gain access to the UST, UST system, UST facility, and property on which the UST or UST system is located. The indicia of ownership held after foreclosure continue to be maintained primarily as protection for a security interest provided that the holder undertakes to sell, re-lease an UST or UST system or facility or property on which the UST or UST system is located, held pursuant to a lease financing transaction (whether by a new lease financing transaction or substitution of the lessee), or otherwise divest itself of the UST or UST system or facility or property on which the UST or UST system is located, in a reasonably expeditious manner, using whatever commercially reasonable means are relevant or appropriate with respect to the UST or UST system or facility or property on which the UST or UST system is located, taking all facts and circumstances into consideration, and provided that the holder does not participate in management (as defined VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 in § 280.210(a)) prior to or after foreclosure. (ii) For purposes of establishing that a holder is seeking to sell, re-lease pursuant to a lease financing transaction (whether by a new lease financing transaction or substitution of the lessee), or divest in a reasonably expeditious manner an UST or UST system or facility or property on which the UST or UST system is located, the holder may use whatever commercially reasonable means as are relevant or appropriate with respect to the UST or UST system or facility or property on which the UST or UST system is located, or may employ the means specified in § 280.210(c)(2). A holder that outbids, rejects, or fails to act upon a written bona fide, firm offer of fair consideration for the UST or UST system or facility or property on which the UST or UST system is located, as provided in § 280.210(c)(2), is not considered to hold indicia of ownership primarily to protect a security interest. (2) Holding foreclosed property for disposition and liquidation. A holder, who does not participate in management prior to or after foreclosure, may sell, re-lease, pursuant to a lease financing transaction (whether by a new lease financing transaction or substitution of the lessee), an UST or UST system or facility or property on which the UST or UST system is located, liquidate, wind up operations, and take measures, prior to sale or other disposition, to preserve, protect, or prepare the secured UST or UST system or facility or property on which the UST or UST system is located. A holder may also arrange for an existing or new operator to continue or initiate operation of the UST or UST system. The holder may conduct these activities without voiding the security interest exemption, subject to the requirements of this subpart. (i) A holder establishes that the ownership indicia maintained after foreclosure continue to be held primarily to protect a security interest by, within 12 months following foreclosure, listing the UST or UST system or the facility or property on which the UST or UST system is located, with a broker, dealer, or agent who deals with the type of property in question, or by advertising the UST or UST system or facility or property on which the UST or UST system is located, as being for sale or disposition on at least a monthly basis in either a real estate publication or a trade or other publication suitable for the UST or UST system or facility or property on which the UST or UST system is located, or a newspaper of general circulation PO 00000 Frm 00100 Fmt 4701 Sfmt 4700 (defined as one with a circulation over 10,000, or one suitable under any applicable federal, state, or local rules of court for publication required by court order or rules of civil procedure) covering the location of the UST or UST system or facility or property on which the UST or UST system is located. For purposes of this provision, the 12month period begins to run from December 6, 1995 or from the date that the marketable title or deed has been issued, approved and recorded, and the holder has obtained access to the UST, UST system, UST facility and property on which the UST or UST system is located, whichever is later, provided that the holder acted diligently to acquire marketable title or deed and to obtain access to the UST, UST system, UST facility and property on which the UST or UST system is located. If the holder fails to act diligently to acquire marketable title or deed or to gain access to the UST or UST system, the 12-month period begins to run from December 6, 1995 or from the date on which the holder first acquires either title to or possession of the secured UST or UST system, or facility or property on which the UST or UST system is located, whichever is later. (ii) A holder that outbids, rejects, or fails to act upon an offer of fair consideration for the UST or UST system or the facility or property on which the UST or UST system is located, establishes by such outbidding, rejection, or failure to act, that the ownership indicia in the secured UST or UST system or facility or property on which the UST or UST system is located are not held primarily to protect the security interest, unless the holder is required, in order to avoid liability under federal or state law, to make a higher bid, to obtain a higher offer, or to seek or obtain an offer in a different manner. (A) Fair consideration, in the case of a holder maintaining indicia of ownership primarily to protect a senior security interest in the UST or UST system or facility or property on which the UST or UST system is located, is the value of the security interest as defined in this section. The value of the security interest includes all debt and costs incurred by the security interest holder, and is calculated as an amount equal to or in excess of the sum of the outstanding principal (or comparable amount in the case of a lease that constitutes a security interest) owed to the holder immediately preceding the acquisition of full title (or possession in the case of a lease financing transaction) pursuant to foreclosure, plus any unpaid interest, rent, or penalties E:\FR\FM\15JYR2.SGM 15JYR2 tkelley on DSK3SPTVN1PROD with RULES2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations (whether arising before or after foreclosure). The value of the security interest also includes all reasonable and necessary costs, fees, or other charges incurred by the holder incident to work out, foreclosure, retention, preserving, protecting, and preparing, prior to sale, the UST or UST system or facility or property on which the UST or UST system is located, re-lease, pursuant to a lease financing transaction (whether by a new lease financing transaction or substitution of the lessee), of an UST or UST system or facility or property on which the UST or UST system is located, or other disposition. The value of the security interest also includes environmental investigation costs (which could include a site assessment, inspection, and/or audit of the UST or UST system or facility or property on which the UST or UST system is located), and corrective action costs incurred under §§ 280.51 through 280.67 or any other costs incurred as a result of reasonable efforts to comply with any other applicable federal, state or local law or regulation; less any amounts received by the holder in connection with any partial disposition of the property and any amounts paid by the borrower (if not already applied to the borrower’s obligations) subsequent to the acquisition of full title (or possession in the case of a lease financing transaction) pursuant to foreclosure. In the case of a holder maintaining indicia of ownership primarily to protect a junior security interest, fair consideration is the value of all outstanding higher priority security interests plus the value of the security interest held by the junior holder, each calculated as set forth in this paragraph (c). (B) Outbids, rejects, or fails to act upon an offer of fair consideration means that the holder outbids, rejects, or fails to act upon within 90 days of receipt, a written, bona fide, firm offer of fair consideration for the UST or UST system or facility or property on which the UST or UST system is located received at any time after six months following foreclosure, as defined in § 280.210(c). A ‘‘written, bona fide, firm offer’’ means a legally enforceable, commercially reasonable, cash offer solely for the foreclosed UST or UST system or facility or property on which the UST or UST system is located, including all material terms of the transaction, from a ready, willing, and able purchaser who demonstrates to the holder’s satisfaction the ability to perform. For purposes of this provision, the six-month period begins to run from December 6, 1995 or from the date that VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 marketable title or deed has been issued, approved and recorded to the holder, and the holder has obtained access to the UST, UST system, UST facility and property on which the UST or UST system is located, whichever is later, provided that the holder was acting diligently to acquire marketable title or deed and to obtain access to the UST or UST system, UST facility and property on which the UST or UST system is located. If the holder fails to act diligently to acquire marketable title or deed or to gain access to the UST or UST system, the six-month period begins to run from December 6, 1995 or from the date on which the holder first acquires either title to or possession of the secured UST or UST system, or facility or property on which the UST or UST system is located, whichever is later. (3) Actions that are not participation in management post-foreclosure. A holder is not considered to be participating in the management of an UST or UST system or facility or property on which the UST or UST system is located when undertaking actions under this part, provided that the holder does not otherwise participate in the management or daily operation of the UST or UST system as provided in § 280.210(a) and § 280.230. Such allowable actions include, but are not limited to, release detection and release reporting, release response and corrective action, temporary or permanent closure of an UST or UST system, UST upgrading or replacement, and maintenance of corrosion protection. A holder who undertakes these actions must do so in compliance with the applicable requirements in this part or applicable state requirements in those states that have been delegated authority by EPA to administer the UST program pursuant to 42 U.S.C. 6991c and 40 CFR part 281. A holder may directly oversee these environmental compliance actions and voluntary environmental actions, and directly hire contractors to perform the work, and is not by such action considered to be participating in the management of the UST or UST system. § 280.220 Ownership of an underground storage tank or underground storage tank system or facility or property on which an underground storage tank or underground storage tank system is located. Ownership of an UST or UST system or facility or property on which an UST or UST system is located.

(a) This part specifies the requirements that state programs must meet for approval by the Administrator under section 9004 of the Solid Waste Disposal Act, and the procedures EPA will follow in approving, revising and withdrawing approval of state programs. (b) State submissions for program approval must be in accordance with the procedures set out in this part. (c) A state may apply for approval under this part at any time after the promulgation of release detection, prevention, and corrective action regulations under § 9003 of the Solid Waste Disposal Act. (d) Any state program approved by the Administrator under this part shall at all times be conducted in accordance with the requirements of this part. General requirements. (a) State program elements. The following substantive elements of a state program must be addressed in a state application for approval: (1) Requirements for all existing and new underground storage tanks: (i) New UST systems (design, construction, installation, and notification); (ii) Upgrading of existing UST systems; (iii) General operating requirements; (iv) Release detection; (v) Release reporting, investigation, and confirmation; (vi) Out-of-service USTs and closure; (vii) Release response and corrective action; (viii) Financial responsibility for UST systems containing petroleum; and (ix) Operator training. (2) Provisions for adequate enforcement of compliance with the above program elements. (b) Final approval. The state must demonstrate that its requirements under each state program element for existing and new UST systems are no less stringent than the corresponding federal requirements as set forth in subpart C of this part. The state must also demonstrate that it has a program that provides adequate enforcement of compliance with these requirements. (c) States with programs approved under this part are authorized to administer the state program in lieu of the federal program and will have primary enforcement responsibility with respect to the requirements of the approved program. EPA retains authority to take enforcement action in approved states as necessary and will PO 00000 Frm 00113 Fmt 4701 Sfmt 4700 Scope and definitions. (a) Scope. (1) The Administrator may approve either partial or complete state programs. A ‘‘partial’’ state program regulates either solely UST systems containing petroleum or solely UST systems containing hazardous substances. If a ‘‘partial’’ state program is approved, EPA will administer the remaining part of the program. A ‘‘complete’’ state program regulates both petroleum and hazardous substance tanks. (2) EPA will administer the UST program in Indian country, except where Congress has clearly expressed an intention to grant a state authority to regulate petroleum and hazardous substance USTs in Indian country. In either case, this decision will not impair a state’s ability to obtain program approval for petroleum or hazardous substances in non-Indian country in accordance with this part. (3) Nothing in this subpart precludes a state from: (i) Adopting or enforcing requirements that are more stringent or more extensive than those required under this part; or (ii) Operating a program with a greater scope of coverage than that required under this part. Where an approved state program has a greater scope of coverage than required by federal law, the additional coverage is not part of the federally-approved program. (b) Definitions. (1) The definitions in 40 CFR part 280 apply to this entire part except as described below. (i) States may use the definitions associated with tank and piping secondary containment as defined in section 9003 of the Solid Waste Disposal Act. (ii) States may use the definitions associated with operator training as described in § 9010 of the Solid Waste Disposal Act. (2) For the purposes of this part the term ‘‘final approval’’ means the approval received by a state program that meets the requirements in § 281.11(b). Subpart B—Components of a Program Application § 281.20 Program application. Any state that seeks to administer a program under this part must submit an application containing the following parts: (a) A transmittal letter from the Governor of the state requesting program approval; E:\FR\FM\15JYR2.SGM 15JYR2 41678 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations (b) A description in accordance with § 281.21 of the state program and operating procedures; (c) A demonstration of the state’s procedures to ensure adequate enforcement; (d) A Memorandum of Agreement outlining roles and responsibilities of EPA and the implementing agency; (e) An Attorney General’s statement in accordance with § 281.25 certifying to applicable state authorities; and (f) Copies of all applicable state statutes and regulations. § 281.21 Description of state program. tkelley on DSK3SPTVN1PROD with RULES2 A state seeking to administer a program under this part must submit a description of the program it proposes to administer under state law in lieu of the federal program. The description of a state’s existing or planned program must include: (a) The scope of the state program: (1) Whether the state program regulates UST systems containing petroleum or hazardous substances, or both; (2) Whether the state program is more stringent or broader in scope than the federal program, and in what ways; and (3) Whether the state has any existing authority in Indian country or has existing agreements with Indian tribes relevant to the regulation of underground storage tanks. (b) The organization and structure of the state and local agencies with responsibility for administering the program. The jurisdiction and responsibilities of all state and local implementing agencies must be delineated, appropriate procedures for coordination set forth, and one state agency designated as a ‘‘lead agency’’ to facilitate communications between EPA and the state. (c) Staff resources to carry out and enforce the required state program elements, both existing and planned, including the number of employees, agency where employees are located, general duties of the employees, and current limits or restrictions on hiring or utilization of staff. (d) An existing state funding mechanism to meet the estimated costs of administering and enforcing the required state program elements, and any restrictions or limitations upon this funding. § 281.22 Procedures for adequate enforcement. A state must submit a description of its compliance monitoring and enforcement procedures, including related state administrative or judicial review procedures. VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 § 281.23 Memorandum of agreement. EPA and the approved state will negotiate a Memorandum of Agreement (MOA) containing proposed areas of coordination and shared responsibilities between the state and EPA and separate EPA and state roles and responsibilities in areas including, but not limited to: Implementation of partial state programs; enforcement; compliance monitoring; EPA oversight; and sharing and reporting of information. At the time of approval, the MOA must be signed by the Regional Administrator and the appropriate official of the state lead agency. § 281.24 Attorney General’s statement. (a) A state must submit a written demonstration from the Attorney General that the laws and regulations of the state provide adequate authority to carry out the program described under § 281.21 and to meet other requirements of this part. This statement may be signed by independent legal counsel for the state rather than the Attorney General, provided that such counsel has full authority to independently represent the state Agency in court on all matters pertaining to the state program. This statement must include citations to the specific statutes, administrative regulations, and where appropriate, judicial decisions that demonstrate adequate authority to regulate and enforce requirements for UST systems. State statutes and regulations cited by the state Attorney General must be fully effective when the program is approved. (b) If a state currently has authority over underground storage tank activities in Indian country, the statement must contain an appropriate analysis of the state’s authority. Subpart C—Criteria for No Less Stringent § 281.30 New UST system design, construction, installation, and notification. In order to be considered no less stringent than the corresponding federal requirements for new UST system design, construction, installation, and notification, the state must have requirements that ensure all new underground storage tanks, and the attached piping in contact with the ground and used to convey the regulated substance stored in the tank, conform to the following: (a) Be designed, constructed, and installed in a manner that will prevent releases for their operating life due to manufacturing defects, structural failure, or corrosion. Unless the state requires manufacturer and installer PO 00000 Frm 00114 Fmt 4701 Sfmt 4700 financial responsibility and installer certification in accordance with section 9003(i)(2) of the Solid Waste Disposal Act, then the state must meet the following: (1) New or replaced tanks and piping must use interstitial monitoring within secondary containment in accordance with section 9003(i)(1) of the Solid Waste Disposal Act except as follows: (i) Underground piping associated with: Airport hydrant systems or fieldconstructed tanks greater than 50,000 gallons or (ii) Underground suction piping that meets § 281.33(d)(2)(ii). (2) New motor fuel dispenser systems installed and connected to an UST system must be equipped with underdispenser containment in accordance with section 9003(i)(1) of the Solid Waste Disposal Act. Note to paragraph (a). Codes of practice developed by nationally recognized organizations and national independent testing laboratories may be used to demonstrate that the state program requirements are no less stringent in this area. (b) Be provided with equipment to prevent spills and tank overfills when new tanks are installed or existing tanks are upgraded, unless the tank does not receive more than 25 gallons at one time. Flow restrictors used in vent lines are not allowable forms of overfill prevention when overfill prevention is installed or replaced. (c) All UST system owners and operators must notify the implementing agency of the existence of any new UST system and notify the implementing agency within a reasonable timeframe when assuming ownership of an UST system using a process designated by the implementing agency. § 281.31 Upgrading existing UST systems. In order to be considered no less stringent than the corresponding federal upgrading requirements, the state must have requirements that ensure existing UST systems meet the requirements of § 281.30; are upgraded to prevent releases for their operating life due to corrosion, spills, or overfills; or are permanently closed with the following exceptions: (a) Upgrade requirements for previously deferred UST systems. Previously deferred airport hydrant fuel distribution systems and UST systems with field-constructed tanks must within three years of the effective date of its state requirements meet the requirements of § 281.30 or be permanently closed. This provision would not apply, however, to states that did not defer these UST systems and E:\FR\FM\15JYR2.SGM 15JYR2 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations already had, prior to the effective date of this provision, existing requirements with specified compliance periods for these types of UST systems. (b) Upgrade requirements for other UST systems. States may allow UST systems to be upgraded if the state determines that the upgrade is appropriate to prevent releases for the operating life of the UST system due to corrosion and spills or overfills. § 281.32 General operating requirements. In order to be considered no less stringent than the corresponding federal general operating requirements, the state must have requirements that ensure all new and existing UST systems conform to the following: (a) Prevent spills and overfills by ensuring that the space in the tank is sufficient to receive the volume to be transferred and that the transfer operation is monitored constantly; (b) Where equipped with cathodic protection, be operated and maintained by a person with sufficient training and experience in preventing corrosion, and in a manner that ensures that no releases occur during the operating life of the UST system; tkelley on DSK3SPTVN1PROD with RULES2 Note to paragraph (b). Codes of practice developed by nationally recognized organizations and national independent testing laboratories may be used to demonstrate the state program requirements are no less stringent. (c) Be made of or lined with materials that are compatible with the substance stored; in order to ensure compatibility, the state requirements must also include provisions for demonstrating compatibility with new and innovative regulated substances or other regulated substances identified by the implementing agency or include other provisions determined by the implementing agency to be no less protective of human health and the environment than the provisions for demonstrating compatibility; (d) At the time of upgrade or repair, be structurally sound and upgraded or repaired in a manner that will prevent releases due to structural failure or corrosion during their operating lives; (e) Have spill and overfill prevention equipment periodically tested or inspected in a manner and frequency that ensures its functionality for the operating life of the equipment and have the integrity of containment sumps used for interstitial monitoring of piping periodically tested in a manner and frequency that prevents releases during the operating life of the UST system; (f) Have operation and maintenance walkthrough inspections periodically conducted in a manner and frequency VerDate Sep<11>2014 19:07 Jul 14, 2015 Jkt 235001 that ensures proper operation and maintenance for the operating life of the UST system; and (g) Have records of monitoring, testing, repairs, and inspections. These records must be made readily available when requested by the implementing agency. § 281.33 Release detection. In order to be considered no less stringent than the corresponding federal requirements for release detection, the state must have requirements that at a minimum ensure all UST systems are provided with release detection that conforms to the following: (a) General methods. Release detection requirements for owners and operators must consist of a method, or combination of methods, that is: (1) Capable of detecting a release of the regulated substance from any portion of the UST system that routinely contains regulated substances—as effectively as any of the methods allowed under this part—for as long as the UST system is in operation. In comparing methods, the implementing agency shall consider the size of release that the method can detect and the speed and reliability with which the release can be detected. (2) Designed, installed, calibrated, operated and maintained so that releases will be detected in accordance with the capabilities of the method; (3) Operated and maintained, and electronic and mechanical components and other equipment are tested or inspected periodically, in a manner and frequency that ensures proper operation to detect releases for the operating life of the release detection equipment. (b) Phase-in of requirements. Release detection requirements must, at a minimum, be applied at all UST systems immediately, except for UST systems previously deferred under § 280.10(a)(1). Release detection requirements must, at a minimum, be scheduled to be applied to those previously deferred UST systems as follows: (1) Immediately when a new previously deferred UST system is installed; and (2) For any previously deferred UST system within three years of the effective date of its state requirements. This provision would not apply, however, to states that did not defer these UST systems and already had, prior to the effective date of this provision, existing release detection requirements with specified compliance periods for these types of UST systems. PO 00000 Frm 00115 Fmt 4701 Sfmt 4700 41679 (c) Requirements for petroleum tanks. All petroleum tanks must meet the following requirements: (1) All petroleum tanks must be sampled, tested, or checked for releases at least monthly, except that tanks installed before October 13, 2015 or upgraded tanks (that is, tanks and piping protected from releases due to corrosion and equipped with both spill and overfill prevention devices) may temporarily use monthly inventory control (or its equivalent) in combination with tightness testing (or its equivalent) conducted every five years for the first 10 years after the tank is installed; and (2) New or replaced petroleum tanks must use interstitial monitoring within secondary containment in accordance with section 9003(i)(1) of the Solid Waste Disposal Act except when the state requires manufacturer and installer financial responsibility and installer certification in accordance with section 9003(i)(2) of the Solid Waste Disposal Act. (d) Requirements for petroleum piping. All underground piping attached to the tank that routinely conveys petroleum must conform to the following: (1) If the petroleum is conveyed under greater than atmospheric pressure: (i) The piping must be equipped with release detection that detects a release within an hour by restricting or shutting off flow or sounding an alarm; and (ii) The piping must have monthly monitoring applied or annual tightness tests conducted. (2) If suction lines are used: (i) Tightness tests must be conducted at least once every three years, unless a monthly method of detection is applied to this piping; or (ii) The piping is designed to allow the contents of the pipe to drain back into the storage tank if the suction is released and is also designed to allow an inspector to immediately determine the integrity of the piping system. (3) Except as provided for in § 281.30(a)(1) new or replaced petroleum piping must use interstitial monitoring within secondary containment in accordance with section 9003(i)(1) of the Solid Waste Disposal Act except when the state requires evidence of financial responsibility and certification in accordance with section 9003(i)(2) of the Solid Waste Disposal Act. (e) Requirements for hazardous substance UST systems. All new hazardous substance UST systems must use interstitial monitoring within secondary containment of the tanks and the attached underground piping that E:\FR\FM\15JYR2.SGM 15JYR2 41680 Federal Register / Vol. 80, No. 135 / Wednesday, July 15, 2015 / Rules and Regulations conveys the regulated substance stored in the tank. For hazardous substance UST systems installed prior to October 13, 2015, owners and operators can use another form of release detection if the owner and operator can demonstrate to the state (or the state otherwise determines) that another method will detect a release of the regulated substance as effectively as other methods allowed under the state program for petroleum UST systems and that effective corrective action technology is available for the hazardous substance being stored that can be used to protect human health and the environment. § 281.34 Release reporting, investigation, and confirmation. In order to be considered no less stringent than the corresponding federal requirements for release reporting, investigation, and confirmation, the state must have requirements that ensure all owners and operators conform with the following: (a) Promptly investigate all suspected releases, including: (1) When unusual operating conditions, release detection signals and environmental conditions at the site suggest a release of regulated substances may have occurred or the interstitial space may have been compromised; and (2) When required by the implementing agency to determine the source of a release having an impact in the surrounding area; and (b) Promptly report all confirmed underground releases and any spills and overfills that are not contained and cleaned up.

This information must be submitted in a timely manner that demonstrates its technical adequacy to protect human health and the environment; and (f) In accordance with § 280.67, the state must notify the affected public of all confirmed releases requiring a plan for soil and groundwater remediation, and upon request provide or make available information to inform the interested public of the nature of the release and the corrective measures planned or taken. § 281.36 Out-of-service UST systems and closure. In order to be considered no less stringent than the corresponding federal requirements for temporarily closed UST systems and permanent closure, the state must have requirements that ensure UST systems conform with the following: (a) Removal from service. All new and existing UST systems temporarily closed must: (1) Continue to comply with general operating requirements, release reporting and investigation, and release response and corrective action; (2) Continue to comply with release detection requirements if regulated substances are stored in the tank; (3) Be closed off to outside access; and (4) Be permanently closed if the UST system has not been protected from corrosion and has not been used in one year, unless the state approves an extension after the owner and operator conducts a site assessment. (b) Permanent closure of UST systems. All tanks and piping must be cleaned and permanently closed in a manner that eliminates the potential for safety hazards and any future releases. The owner or operator must notify the state of permanent UST system closures. The site must also be assessed to determine if there are any present or were past releases, and if so, release response and corrective action requirements must be complied with. (c) All UST systems taken out of service before the effective date of the PO 00000 Frm 00116 Fmt 4701 Sfmt 4700 federal regulations must permanently close in accordance with paragraph (b) of this section when directed by the implementing agency. § 281.37 Financial responsibility for UST systems containing petroleum.

Revising Underground Storage Tank Regulations--Revisions to 
Existing Requirements and New Requirements for Secondary Containment 
and Operator Training

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA or the Agency) is 
making certain revisions to the 1988 underground storage tank (UST) 
regulation and to the 1988 state program approval (SPA) regulation. 
These changes establish Federal requirements that are similar to key 
portions of the Energy Policy Act of 2005 (EPAct); they also update the 
1988 UST and SPA regulations. Changes to the regulations include: 
Adding secondary containment requirements for new and replaced tanks 
and piping; adding operator training requirements; adding periodic 
operation and maintenance requirements for UST systems; addressing UST 
systems deferred in the 1988 UST regulation; adding new release 
prevention and detection technologies; updating codes of practice; 
making editorial corrections and technical amendments; and updating 
state program approval requirements to incorporate these new changes. 
EPA thinks these changes will protect human health and the environment 
by reducing the number of releases to the environment and quickly 
detecting releases, if they occur.

DATES: This rule is effective October 13, 2015.

    EPA is revising these regulations under the authority of sections 
2002, 9001, 9002, 9003, 9004, 9005, 9006, 9007, 9010, and 9012 of the 
Solid Waste Disposal Act (SWDA) of 1965, as amended (commonly known as 
the Resource Conservation and Recovery Act (RCRA)) [42 U.S.C. 6912, 
6991, 6991(a), 6991(b), 6991(c), 6991(d), 6991(e), 6991(f), 6991(i), 
and 6991(k)].

III. Background

A. Changes to the UST Regulations

    After reviewing and incorporating comments received during the five 
month public comment period, EPA is finalizing certain changes to the 
1988 UST regulation in 40 CFR part 280. EPA is also revising its SPA 
regulation in 40 CFR part 281 to incorporate the changes in 40 CFR part 
280.
    These revisions strengthen the 1988 UST regulation by increasing 
the emphasis on properly operating and maintaining equipment. The 1988 
UST regulation required owners and operators to have spill, overfill, 
and release detection equipment in place for their UST systems, but did 
not require proper operation and maintenance for some of that 
equipment. For example, EPA required spill prevention equipment to 
capture drips and spills when the delivery hose is disconnected from 
the fill pipe, but did not require periodic testing of that equipment. 
These revisions require that UST equipment is operated and maintained 
properly, which will improve environmental protection. These revisions 
also acknowledge improvements in technology over the last 26 years, 
including the ability to detect releases from UST systems deferred in 
the 1988 UST regulation.
    EPA is revising the 1988 UST regulation to:
     Establish federal requirements that are similar to certain 
key provisions of the Energy Policy Act of 2005;
     Ensure owners and operators properly operate and maintain 
their UST systems;
     Address UST systems deferred in the 1988 UST regulation;
     Include updates to current technology and codes of 
practices;
     Make technical and editorial corrections; and
     Update the SPA regulation to address the changes listed 
above.
    In 1988, EPA first promulgated the UST regulation (40 CFR part 280) 
to prevent, detect, and clean up petroleum releases into the 
environment. The 1988 UST regulation required new UST systems to be 
designed, constructed, and installed to prevent releases; existing UST 
systems had to be upgraded to prevent releases. In addition, owners and 
operators were required to perform release detection, demonstrate 
financial responsibility, and clean up releases.
    The Energy Policy Act of 2005 amended Subtitle I of SWDA, the 
statute that authorized the UST program. Key Energy Policy Act 
provisions (such as secondary containment and operator training) apply 
to all states and United States' territories, hereafter referred to as 
states, receiving federal Subtitle I money under SWDA, regardless of 
their state program approval status, but do not apply in Indian 
country. The United States has a unique legal relationship with 
federally recognized Indian tribes. This government to government 
relationship includes recognizing the rights of tribes as sovereign 
governments with the right to self-determination and acknowledging the 
federal government's trust responsibility to tribes. As a result, EPA 
directly implements the UST program in Indian country.
    In order to establish federal UST requirements that are similar to 
the UST secondary containment and operator training requirements of the 
Energy Policy Act, EPA decided to revise the 1988 UST regulation. These 
revisions also fulfill objectives in EPA's August 2006 UST Tribal 
Strategy,\1\ where both EPA and tribes recognized the importance of 
requirements that ensure parity in program implementation among states 
and in Indian country. Secondary containment will reduce releases to 
the environment by containing them within a secondary area and 
detecting them before they reach the environment. Operator training 
will educate UST system operators and help them prevent releases by 
complying with the regulation and performing better operation and 
maintenance of their UST systems.
---------------------------------------------------------------------------

    \1\ 2006 Tribal Strategy, https://epa.gov/oust/fedlaws/tribalst.htm.
---------------------------------------------------------------------------

    Since the beginning of the UST program, preventing petroleum and 
hazardous substance releases from UST systems into the environment has 
been one of the primary goals of the program. Although EPA and our 
partners have made significant progress in reducing the number of new 
releases, approximately 6,000 releases are discovered each year as of 
FY 2013.\2\ Lack of proper operation and maintenance of UST systems is 
the main cause of new releases. Information on sources and causes of 
releases shows that releases from tanks are less common than they once 
were. However, releases from piping and spills and overfills associated 
with deliveries have emerged as more common problems. In addition, 
releases at the dispenser are one of the leading sources of releases. 
Finally, data show that release detection equipment is only detecting 
approximately 50 percent of releases it is designed to detect. These 
problems are partly due to improper operation and maintenance. See 
section IV.B, Additional Requirements for Operation and Maintenance for 
a more detailed discussion of problems.

    EPA relied on two draft causes of releases studies to help support 
this final UST regulation. Petroleum Releases at Underground Storage 
Tank Facilities in Florida contains release data on 512 releases from 
new and

[[Page 41568]]

upgraded tanks in Florida.\3\ The second draft study, Evaluation of 
Releases from New and Upgraded Underground Storage Tank Systems, 
contains release data on 580 releases from new and upgraded tanks in 23 
states across the Northeast, South, and Central parts of the United 
States.\4\ Taken together, these draft studies provide information on 
1,092 releases in 24 of 50 states. The data in the two studies 
generally provide a representative sampling of releases across the 
United States, because nearly half of the states contributed to the 
studies. Both drafts were peer reviewed but never finalized because 
passage of the Energy Policy Act of 2005 required a reallocation of 
personnel and resources. Even though these studies were never 
finalized, the underlying data and calculations can be used to support 
this final UST regulation because that information did not change as a 
result of the peer review process. These studies are available in the 
docket for this final action.

    Many USTs currently in the ground were upgraded to meet the spill, 
overfill, corrosion protection, and release detection requirements in 
the 1988 UST regulation. As these USTs continue to age, it is vital 
that we ensure they are still working as intended. These revisions to 
the 1988 UST regulation focus on ensuring equipment is working, rather 
than requiring UST owners and operators to replace or upgrade equipment 
already in place. The 1988 UST regulation requires owners and operators 
to use equipment that could help prevent releases. These revisions 
highlight the importance of operating and maintaining UST equipment so 
releases to the environment are prevented or quickly detected.
    This final UST regulation addresses UST systems deferred in the 
1988 UST regulation by removing the deferral and regulating UST systems 
with field-constructed tanks, airport hydrant fuel distribution systems 
that meet the UST definition, and UST systems storing fuel solely for 
use by emergency power generators. Note that aboveground storage tanks 
associated with UST systems with field-constructed tanks and airport 
hydrant fuel distribution systems that meet the UST definition are 
partially excluded in this final UST regulation. EPA is partially 
excluding wastewater treatment tank systems that are not part of a 
wastewater treatment facility regulated under sections 402 or 307(b) of 
the Clean Water Act, USTs containing radioactive material, and 
emergency generator UST systems at nuclear power generation facilities 
regulated by the Nuclear Regulatory Commission. See section IV.C, 
Addressing Deferrals, for more information.
    EPA is revising the 1988 SPA regulation (40 CFR part 281) to 
address the changes to 40 CFR part 280. By doing so, states will 
generally need to adopt the 40 CFR part 280 changes finalized today in 
order to obtain or retain SPA.
    Please note that, although not a part of this final UST regulation, 
owners and operators may also be subject to other requirements related 
to underground storage tank systems. For example, EPA's Office of Air 
and Radiation has national emission standards for hazardous air 
pollutants for various source categories, including gasoline dispensing 
facilities (see 40 CFR part 63). These standards include some testing 
for UST systems, depending on the monthly throughput of the facility.
    Finally, EPA allows owners and operators the flexibility to 
maintain either paper or electronic records to demonstrate compliance 
with this final UST regulation. EPA encourages owners and operators to 
maintain records electronically, which promotes innovation \5\ and 
simplifies compliance by using 21st century technology tools.\6\

---------------------------------------------------------------------------

B. History of the UST Laws and Regulations

    In 1984, Congress responded to the increasing threat to groundwater 
posed from leaking USTs by adding Subtitle I to SWDA, commonly referred 
to as RCRA. Subtitle I of SWDA required EPA to develop a comprehensive 
regulatory program for USTs storing petroleum or certain hazardous 
substances, ensuring that the environment and human health are 
protected from UST releases. In 1986, Congress amended Subtitle I of 
SWDA and created the Leaking Underground Storage Tank Trust Fund to 
implement a cleanup program and pay for cleanups at sites where the 
owner or operator is unknown, unwilling, or unable to respond, or which 
require emergency action.
    In 1988, EPA promulgated the UST regulation (40 CFR part 280), 
which set minimum standards for new UST systems and required owners and 
operators of existing UST systems to upgrade, replace, or close them. 
In addition, after 1988 owners and operators were required to report 
and clean up releases from their USTs. The 1988 UST regulation set 
deadlines for owners and operators to meet those requirements by 
December 22, 1998. Owners and operators who chose to upgrade or replace 
had to ensure their UST systems included spill and overfill prevention 
equipment and were protected from corrosion. In addition, owners and 
operators were required to monitor their UST systems for releases using 
release detection (phased in through 1993, depending on when their UST 
systems were installed). Finally, owners and operators were required to 
demonstrate financial responsibility (phased in through 1998), which 
ensured they have financial resources to pay for cleaning up releases. 
EPA has not significantly changed the UST regulation since 1988.
    In 1988, EPA also promulgated a regulation for state program 
approval (40 CFR part 281). Since states are the primary implementers 
of the UST program, EPA established a process where state programs 
could operate in lieu of the federal program, if states met certain 
requirements and obtained state program approval from EPA. The state 
program approval regulation describes minimum requirements states must 
meet so their programs can be approved and operate in lieu of the 
federal program.
    In 2005, the Energy Policy Act further amended Subtitle I of SWDA. 
The Energy Policy Act required states receiving Subtitle I money from 
EPA to meet certain requirements. EPA developed grant guidelines for 
states regarding: Operator training; inspections; delivery prohibition; 
secondary containment; financial responsibility for manufacturers and 
installers; public record; and state compliance reports on government 
USTs.\7\ The operator training and secondary containment requirements 
are two major pieces of the Energy Policy Act that did not apply in 
Indian country, but will now apply with publication of this final UST 
regulation.

C. Potential Impact of This Regulation

    This final UST regulation will improve parity in program 
implementation among states and in Indian country. This regulation is 
adding to the federal UST regulation

[[Page 41569]]

certain requirements, which will apply in Indian country. These 
requirements are similar to the Energy Policy Act's operator training 
and secondary containment requirements, which apply in states receiving 
federal Subtitle I money from EPA. This action will also further 
strengthen protection of human health and the environment from UST 
releases by increasing the emphasis on proper operation and maintenance 
of release prevention and release detection equipment. These revisions 
also reflect improvements in technology that allow for the ability to 
prevent and quickly detect releases for many tank systems currently 
deferred from regulation under Subtitle I.
    The regulatory changes finalized today impose costs to owners and 
operators of existing regulated UST systems and owners and operators of 
USTs deferred in the 1988 UST regulation, as well as costs associated 
with state review of the changes. EPA prepared an analysis of the 
potential incremental costs and benefits associated with this action. 
This analysis is contained in the regulatory impact analysis (RIA) 
titled Assessment of The Potential Costs, Benefits, and Other Impacts 
of the Final Revisions to EPA's Underground Storage Tank Regulations, 
which is available in the docket for this action. Numerous commenters 
submitted input relaying their concerns about the costs and feasibility 
of specific requirements in the 2011 proposed UST regulation. EPA 
considered these comments and adjusted this final UST regulation to 
alleviate some of the burden on owners and operators. For example, EPA 
is requiring testing of spill prevention equipment every three years 
instead of annually. EPA also adjusted some of the assumptions 
underlying the RIA to reflect information received from commenters. For 
example, several commenters provided water disposal costs associated 
with spill bucket testing. While the RIA for the 2011 proposed UST 
regulation assumed these costs were part of the spill prevention 
testing cost, EPA adjusted this assumption to reflect that, in some 
cases, owners and operators will incur additional costs to dispose of 
the water. A summary of these impacts is provided in section VI, 
Overview of Estimated Costs and Benefits, and in the table below. Note 
that due to data and resource constraints, EPA was unable to quantify 
or monetize some of this final UST regulation's benefits, including 
avoidance of human health risks, groundwater protection, ecological 
benefits, and mitigation of acute exposure events and large-scale 
releases (e.g., releases from airport hydrant distribution systems and 
UST systems with field-constructed tanks).

* Totals may not add up due to rounding

    EPA also prepared a risk assessment for the 2011 proposed UST 
regulation titled Risk Analysis to Support Potential Revisions to 
Underground Storage Tank (UST) Regulations. The risk assessment 
examined potential impacts to groundwater and subsequent chemical 
transport, exposure, and risk. EPA decided not to spend resources to 
finalize the risk assessment through a formal peer review process, 
because the results from the risk assessment did not materially impact 
the RIA. Changes brought about by this final UST regulation are not 
expected to significantly alter these outcomes. The risk assessment 
developed for the 2011 proposed UST regulation is available for review 
in the docket.

D. EPA's Process in Deciding Which Changes To Incorporate in the 
Regulations

    After the Energy Policy Act became law, EPA recognized a need to 
revise the 1988 UST regulation. The Energy Policy Act required 
additional measures to protect groundwater (either with secondary 
containment or financial responsibility for manufacturers and 
installers) and operator training requirements in states receiving 
federal Subtitle I money from EPA. However, no similar requirements 
would apply in Indian country until EPA promulgates a regulation. Both 
EPA and tribes are committed to ensuring program parity between states 
and in Indian country, and this final UST regulation achieves this 
parity.
    For the past 26 years, the 1988 UST regulation worked well to 
provide environmental protection. However, over two decades of 
experience implementing the UST program have shown there are a number 
of areas where EPA can improve the UST program and increase 
environmental protection. For example, updating the UST regulation to 
reflect current technologies and ensuring release prevention and 
release detection equipment are properly operated and maintained have 
surfaced as areas needing improvement and are included as part of this 
final UST regulation.
    Throughout the regulatory development process, EPA embraced an 
open, inclusive, and transparent process so all UST stakeholders had an 
opportunity to share their ideas and concerns. EPA recognizes concerns 
about costs to owners and operators and the importance of limiting 
requirements for retrofits. In developing this action, EPA reached out 
to stakeholders involved in all aspects of the tank program, provided 
multiple opportunities for sharing ideas, and kept stakeholders 
informed of progress.
    As a result of the information collected during our extensive 
outreach to stakeholders, EPA published proposed regulations in the 
November 2011 Federal Register.\8\ In order to ensure all stakeholders 
had an opportunity to comment, EPA provided a five month public comment 
period on the proposed UST and SPA regulations.
---------------------------------------------------------------------------

---------------------------------------------------------------------------

    A number of commenters provided general input on EPA's 2011 
proposal to update the UST and SPA regulations. Many commenters 
appreciated the extensive stakeholder outreach EPA conducted prior to 
drafting the proposed changes to the UST and SPA

[[Page 41570]]

regulations. A few commenters believed EPA's outreach was not adequate. 
EPA conducted extensive stakeholder outreach before publishing the 
proposal; we held more than 100 meetings with stakeholders during the 
two years prior to issuing the 2011 proposed UST and SPA regulations. 
To further understand comments and concerns, EPA continued to meet with 
all interested stakeholders during and after the five month public 
comment period.
    Most commenters expressed support for the general revisions to the 
1988 UST and SPA regulations. They supported updating the regulations 
because technology has changed a great deal since the 1980s. Many 
commenters provided specific concerns on particular topics in the 2011 
proposed UST and SPA regulations. We discuss these comments throughout 
the preamble for this action. Several commenters opposed the changes to 
the regulations due to concerns about potential costs on owners, 
especially small businesses. A few commenters requested EPA withdraw 
the entire proposal and conduct a small business advocacy review panel 
under the Regulatory Flexibility Act. EPA carefully considered the 
potential impacts of the proposal on small businesses and determined 
that a small business panel was not required. EPA also considered all 
of the comments submitted during the public comment period, including 
those concerns regarding the potential costs on small businesses, and 
worked to minimize those costs by making certain changes to the final 
regulations. EPA did not change this final UST and SPA regulations when 
comments were beyond the scope of the regulations or beyond EPA's 
statutory authority.

E. Implementation Timeframe

    This final UST regulation aligns the implementation time frames for 
the new operator training, operation and maintenance, and previously 
deferred UST system requirements. The table below provides the 
implementation time frames for each of the new requirements.

------------------------------------------------------------------------

    EPA proposed different implementation time frames for the various 
requirements, and for several requirements, a phased in approach based 
on tank age. Based on commenter input, EPA is not using the phased in 
approach and instead is requiring owners and operators to meet the 
requirements as described in the implementation table above. In 
addition, with one exception EPA is aligning implementation of the 
requirements in this final UST regulation to begin on the effective 
date of the UST regulation or three years after the effective date of 
the UST regulation. The requirements implemented on the effective date 
of the final UST regulation are those that either do not require 
significant education and outreach or apply to new installations, 
repairs, or releases. EPA is allowing up to three years for owners and 
operators to implement the requirements that require significant 
outreach, equipment to be upgraded or installed (such as for previously 
deferred UST systems), or scheduling and testing. Three years allows 
ample time for implementing agencies to educate owners and operators 
about this new requirements and allows owners and operators to schedule 
testing. The exception to implementing the requirements immediately or 
in three years is that EPA is implementing the secondary containment 
requirement 180 days after the effective date of the UST regulation. 
The 180 day time frame allows flexibility for those owners and 
operators who have concrete plans but have not yet applied for or 
obtained approvals or permits for a new UST system installation.
---------------------------------------------------------------------------

    \9\ Note that EPA is requiring owners and operators to also 
submit a one-time notification of existence for these UST systems 
within 3 years of the effective date of this final UST regulation. 
Owners and operators must demonstrate financial responsibility when 
they submit the one-time notification form
---------------------------------------------------------------------------

IV. Revisions to the Requirements for Owners and Operators of 
Underground Storage Tank Systems

    The following sections describe this final UST regulation, starting 
with establishing new requirements for operator training and secondary 
containment. The next four sections

[[Page 41571]]

address changes to the 1988 UST regulation, organized by topic: 
Additional requirements for operation and maintenance; addressing UST 
systems deferred in the 1988 UST regulation; other changes to improve 
release prevention and release detection; and general updates to the 
1988 UST regulation. Finally, there is a section describing alternative 
options considered.

A. Establishing Federal Requirements for Operator Training and 
Secondary Containment

1. Operator Training
    This final UST regulation adds a new subpart J, which contains 
operator training requirements to ensure properly trained individuals 
operate all regulated UST systems. The operator training provision of 
the Energy Policy Act of 2005 requires implementing agencies, as a 
condition of receiving federal Subtitle I money, develop state-specific 
training requirements for three classes of UST system operators. EPA 
issued grant guidelines that provide minimum requirements state 
operator training programs must include in order for states to continue 
receiving federal Subtitle I money.\10\ All states are implementing or 
plan to implement operator training. The EPAct did not specifically 
require operator training in Indian country. To bring UST systems in 
Indian country to the same level of protection as UST systems in 
states, this final UST regulation implements operator training 
requirements.
---------------------------------------------------------------------------

    \10\ Grant Guidelines To States For Implementing The Operator 
Training Provision Of The Energy Policy Act Of 2005: www.epa.gov/oust/fedlaws/optraing.htm.
---------------------------------------------------------------------------

    This final UST regulation closes the gap in coverage and ensures 
all operators designated as Class A, B, or C operators are trained 
according to their level of responsibility. Sufficiently training 
designated UST operators will increase compliance with regulatory 
requirements. In addition, operator training should decrease UST system 
releases by educating Class A, B, and C operators about their UST 
system requirements and result in greater protection of human health 
and the environment.
    The operator training requirements in this final UST regulation are 
consistent with the requirements in EPA's operator training grant 
guidelines for states. In both, EPA establishes minimum operator 
training requirements, yet allows flexibility to tailor training 
programs for specific needs. This means that although there may be 
variations among operator training programs, all Class A, B, and C 
operators will have a minimum level of knowledge about their UST system 
requirements.
Definitions
    EPA is adding definitions for the three operator classes requiring 
training to distinguish them from the term operator originally defined 
in the 1988 UST regulation and maintained in this final UST regulation. 
Only if Class A, B, or C operators meet the definition of operator will 
they be subject to the same responsibilities and liabilities as an 
operator. EPA's definitions of Class A, B, and C operators do not 
relieve UST system owners and operators from legal responsibility for 
complying with the UST regulation. EPA based the three operator class 
definitions on duties each typically perform at UST facilities. 
Commenters on the 2011 proposed UST regulation indicated this final UST 
regulation should further differentiate Class A, B, and C operators 
from EPA's definition of operator. EPA agrees with commenters and is 
changing the title of Sec.  280.241 to Designation of Class A, B, and C 
operators in the final UST regulation. This change correctly identifies 
the individuals who must be designated.
    With the exception of the definition for the Class C operator, the 
operator class definitions remain unchanged from the 2011 proposed UST 
regulation. Several commenters pointed out that UST system owners and 
operators were, at the time of the 2011 proposed UST regulation, using 
contractors to perform Class C operator functions. Some commenters 
believed EPA was restricting the use of a contractor as a Class C 
operator since the proposal required a Class C operator to be an 
employee. EPA agrees; we are removing the restriction. EPA does not 
intend for the operator training requirements to restrict UST system 
owners and operators who are using contractors to operate their UST 
systems.
    EPA added a definition for training program in the 2011 proposed 
UST regulation; we are modifying it in this final UST regulation. It is 
important that training programs for Class A, B, and C operators 
include both sharing information and evaluating knowledge. Several 
commenters requested clarification on how EPA expected knowledge to be 
verified. To address these requests, EPA changed the definition of 
training program by adding the phrase ``through testing, practical 
demonstration, or another approach acceptable to the implementing 
agency.'' This addition clarifies the definition and makes it 
consistent with how the term is used in this final UST regulation.
How Operators Are Designated
    This final UST regulation indicates how UST owners and operators 
are to designate the three operator classes for their facilities. UST 
owners and operators must designate at least one Class A and B operator 
at each facility. Class A and B operators may provide training to Class 
C operators, which should help UST owners and operators comply with 
this requirement. The UST owner and operator must ensure Class C 
operator training is documented.
    Because Class C operators' duties typically require them to provide 
initial responses to emergencies, individuals who meet the Class C 
operator definition must be designated as such and trained in UST 
system emergency response--for example response to release detection 
alarms, spills, or releases. EPA received several comments on the 2011 
proposed UST regulation requesting we require only one Class C operator 
be designated. The final UST regulation requires all individuals who 
meet the definition of Class C operator be trained. EPA maintains that 
the initial response to emergencies provided by this operator class is 
important to environmental protection. Requiring training for all 
individuals who meet the Class C operator definition will increase the 
likelihood UST system emergencies are quickly and appropriately 
addressed. This does not mean all workers need to be trained. For 
example, numerous workers at convenience stores do not control or 
monitor dispensing or sale of petroleum products, nor are they 
responsible for initial alarms. As a result, it is unnecessary to 
designate and train these individuals to meet Class C operator training 
requirements.
    In addition, EPA acknowledges some readers might misinterpret that 
control of the dispensing operation described in the definition of the 
Class C operator applies to anyone fueling a vehicle. The level of UST 
system control and responsibility of individuals who must be trained 
excludes customers who are pumping product into their vehicles. For 
example, police officers using an unmanned facility would not have to 
meet Class C operator training requirements unless they are 
responsible, as specifically tasked by UST system owners and operators, 
to respond to emergencies and alarms caused by spills or releases from 
the UST system.
    In the preamble to the 2011 proposed UST regulation, EPA 
acknowledged that many UST owners and operators might

[[Page 41572]]

want to designate one person at an UST facility to fulfill more than 
one class of operator. This final UST regulation allows one person to 
serve in multiple operator classes; however, that person must be 
trained for each class designated.
    EPA is aware owners and operators rely on contractors to perform 
various UST system tasks, including those of Class A, B, and C 
operators. Because of the current use of contractors, EPA is allowing 
UST owners and operators to designate contractors as their Class A, B, 
and C operators, as long as they are trained in all areas for the class 
of operator designated. UST owners and operators must maintain 
documentation containing individual names (not just company names) of 
Class A, B, and C operators. This will allow implementing agencies to 
use individual names, rather than company names, when verifying 
training, retraining, and refresher training.
Who Must Be Trained
    This final UST regulation requires training for designated Class A, 
B, and C operators at UST systems regulated under Subtitle I. This 
includes UST systems at attended and unattended facilities. An 
unattended UST facility means a Class A, B, or C operator might not be 
present when a facility is operating. Nonetheless, even for unattended 
UST facilities, owners and operators must designate and train Class A, 
B, and C operators.
Requirements for Operator Training
    In the operator training grant guidelines for states, EPA based the 
three operator classes on duties each typically perform at UST 
facilities. Building on that, this final UST regulation requires each 
person designated in an operator class to participate in a specific 
training program or pass an examination comparable to the training 
program.
     For Class A operators, the training program must teach and 
evaluate their knowledge to make informed decisions regarding 
compliance and determine whether appropriate people are performing the 
operation, maintenance, and recordkeeping requirements for UST systems.
     For Class B operators, the training program must teach and 
evaluate their knowledge and skills to implement UST regulatory 
requirements on typical UST system components or site-specific 
equipment at UST facilities.
     For Class C operators, the training program must teach and 
evaluate their knowledge to take appropriate action, including 
notifying appropriate authorities, in response to emergencies or alarms 
caused by spills or releases from UST systems.
     For all operator classes, the test is based on the 
training program and evaluates the minimum knowledge required for the 
operator class.
    EPA received several comments on the description of Class C 
operator training requirements. One commenter suggested EPA should 
clarify the scope of emergencies a Class C operator is trained on. This 
final UST regulation requires Class C operators receive training on 
emergencies or alarms caused by spills or releases from operating UST 
systems. EPA also agrees with the comment regarding Class C operator 
training avoiding triggering the Hazardous Waste Operations and 
Emergency Response (HAZWOPER) standard. HAZWOPER is the United States' 
recognized standard of safety requirements employers and their 
subcontractors or public sector responders must meet in order to 
conduct cleanups or emergency response operations. The level of 
training in this standard is beyond that which EPA intends for Class C 
operators. This final UST regulation modifies the training requirements 
for Class C operators and clarifies that appropriate actions Class C 
operators can take include notifying appropriate authorities.
    For each class of operator, EPA considered developing specific 
training curricula prescribing length of training, topic areas, and 
trainer qualifications. Instead, this final UST regulation provides 
general criteria and requirements, because they provide flexibility 
while ensuring each class of operator is trained in a way that is 
comparable to EPA's operator training grant guidelines for states. EPA 
also modified the lists of training requirements for Class A and B 
operators from those identified in the 2011 proposal. The modifications 
made it clearer that new operation and maintenance inspection and 
testing, and compatibility demonstration requirements must be covered 
by operator training programs and comparable examinations.
    EPA received several comments regarding restrictions on who may 
develop and administer the evaluation component of training, as well as 
restrictions on who may train Class A and B operators. This final UST 
regulation removes those restrictions because they could prohibit in-
house and other potentially viable training. EPA supports a variety of 
operator training approaches. However, for retraining, EPA is revising 
language in Sec.  280.244 to address conflicts of interest. This final 
UST regulation requires the training program or comparable examination 
to be developed or administered by an independent organization, the 
implementing agency, or a recognized authority. These retraining 
restrictions will help address any ineffective training approaches.
    This final UST regulation allows a variety of ways to train 
operators, including classroom, computer based, hands on, and any 
combination of these. In lieu of completing a training program, Class 
A, B, or C operators can pass a comparable examination--such as 
classroom, Internet, or computer based--that meets the requirements for 
operator training described in this final UST regulation.
When Designated Operators Must Complete Operator Training
    This final UST regulation requires UST owners and operators ensure 
all Class A, B, and C operators successfully complete a training 
program or a comparable examination within three years of the effective 
date of this final UST regulation. EPA proposed a phased in approach 
over three years, based on UST installation dates because older USTs 
potentially pose a greater risk to the environment and Class A, B, and 
C operators of those systems should be trained first. EPA received 
comments strongly indicating EPA should not phase in the operator 
training requirements. EPA agrees with commenters that it is less 
confusing to establish a single compliance date for this requirement. 
EPA is aligning implementation of operator training with the three year 
inspection requirement, which will make it easier for UST system owners 
and operators to comply.
    Consistent with EPA's operator training grant guidelines, new 
operators designated after the three year implementation period must be 
trained as follows:
     Class A and B operators must be trained within 30 days of 
assuming duties
     Class C operators must be trained before they assume their 
duties because they must be able to immediately respond to emergencies
Retraining
    Class A and B operators are responsible for ensuring their UST 
systems are compliant. Generally, Class A and B operators need to be 
retrained if the UST systems they are responsible for are determined to 
be out of compliance. At a minimum, retraining must cover those areas 
the

[[Page 41573]]

implementing agency determines are out of compliance. Retraining must 
be completed within 30 days of the implementing agency's final 
determination of noncompliance. This final UST regulation allows 
designated operators to take annual refresher training in lieu of 
retraining, as long as all training areas required by regulation are 
covered. Designated operators must be subject to the annual refresher 
training in place at the time of the violation.
    This final UST regulation also allows implementing agencies to 
waive the retraining requirement. Unless waived, Class A and B 
operators must complete retraining according to Sec.  280.244. EPA 
recommends the waiver be in writing. In waiving the requirement, EPA 
expects the implementing agency to consider factors such as the 
severity and areas of noncompliance. For example, retraining should not 
be required for equipment found inoperative during an inspection if one 
of the following apply: The owner and operator was unaware of the 
problem and operation and maintenance records indicate the equipment 
was operating during the most recent test or inspection; or the owner 
or operator is aware of the problem and has scheduled a timely repair. 
In those instances where UST system noncompliance violations do not 
warrant retraining, EPA encourages implementing agencies to provide 
information about the compliance issue to Class A and B operators so 
they are able to return their facilities to compliance. This provides 
greater flexibility for UST owners and operators to meet the retraining 
requirement. This final UST regulation is consistent with EPA's 
retraining requirement for noncompliance with significant operational 
compliance requirements and an annual refresher training allowance in 
our operator training grant guidelines for states.
    This final UST regulation addresses comments about the terms 
independent trainer and independent organization in the retraining 
requirement at Sec.  280.244. In this section, EPA is requiring that a 
training program or comparable examination be developed, administered, 
or both by an independent organization, the implementing agency, or 
recognized authority. A recognized authority includes, but is not 
limited to, tribes recognized by the U.S. Department of Interior Bureau 
of Indian Affairs. The development, administration, or both by an 
independent organization applies to all training approaches (classroom, 
Internet based, testing, etc.) and provides sufficient control for the 
implementing agency to address conflict of interest and other concerns 
during retraining.
    EPA considered requiring retraining when UST facilities change 
equipment, but decided this would be a significant burden on both the 
regulated community and implementing agencies. However, if an UST 
system is out of compliance because of an equipment change, EPA is 
requiring that UST owners and operators ensure Class A and B operators 
are retrained as discussed above.
Documentation
    This final UST regulation requires owners and operators maintain 
records on currently designated Class A, B, and C operators, rather 
than records on all Class A, B, and C operators for the previous three 
years, as proposed. EPA is requiring owners and operators maintain 
basic information to document Class A, B, and C operators and confirm 
they are appropriately trained. For example, classroom training records 
must be signed by the trainer and include information about the 
training company; computer based training records do not require a 
signature, but must indicate the name of the training program and the 
Web address, if Internet based. This final UST regulation also modifies 
Sec.  280.245(b)(1) by clarifying that the requirement for a record of 
training is also applicable when Class A or B operators train Class C 
operators. UST owners and operators must document verification of 
training or retraining for each class of operator. Owners and operators 
must maintain records verifying training or retraining as long as Class 
A, B, and C operators are designated at the facility.
2. Secondary Containment
    This final UST regulation adds new requirements for secondary 
containment and interstitial monitoring of new and replaced tanks and 
piping along with under-dispenser containment (UDC) of new dispenser 
systems. Data from release sites show a higher number of releases from 
single walled tanks and piping when compared to secondarily contained 
systems.11 12 These new requirements will prevent regulated 
substances from reaching the environment and ensure a consistent level 
of environmental protection for regulated UST systems across the United 
States.

    The Energy Policy Act of 2005 requires implementing agencies, as a 
condition of receiving federal Subtitle I money, implement additional 
measures to protect groundwater. Under EPAct, implementing agencies' 
choices to protect groundwater are: Secondary containment (including 
UDC); or financial responsibility for manufacturers and installers (and 
installer certification). All states are implementing or plan to 
implement secondary containment. The EPAct did not specifically require 
additional measures to protect groundwater in Indian country. To bring 
UST systems in Indian country to the same level of environmental 
protection as UST systems in states, this final UST regulation 
implements secondary containment requirements for new and replaced 
tanks and piping along with UDC underneath all new dispenser systems.
    The EPAct requires states that receive federal Subtitle I money 
(and choose the secondary containment option) to have secondary 
containment and UDC for tanks, piping, and dispensers only if they are 
installed or replaced within 1,000 feet of an existing community water 
system or potable drinking water well.\13\ However, EPA is requiring 
all new and replaced tanks and piping to install secondary containment 
and new dispenser systems to install UDC for these reasons:
---------------------------------------------------------------------------

    \13\ Title XV, Subtitle B, Section 1530 of Energy Policy Act of 
2005, Public Law 109-58, August 8, 2005.
---------------------------------------------------------------------------

     Nearly all new and replaced tanks and piping are installed 
within 1,000 feet of an existing community water system (CWS) or 
potable drinking water well (PDWW). An UST listed with a commercial 
ownership type (i.e., gas station) is typically located within 1,000 
feet of an on-site well or public water line because nearly all 
commercially-owned facilities with USTs require water utilities in 
order to operate. In addition, privately owned facilities (i.e., fleet 
fueling for non-marketers) are generally in close proximity to some 
type of water supply, given that these sites are typically combined 
with other functional operations (office, maintenance, manufacturing, 
etc.) and require water for restrooms, water fountains, shops, etc.;

within 1,000 feet of a CWS or PDWW informed EPA that installations of 
single walled tanks or piping are not occurring; and
     Secondary containment for all new and replaced tanks and 
piping along with UDC for new dispenser systems will help protect other 
sensitive areas, such as designated source water protection areas, 
natural springs, and surface waters.
    The EPAct requires under-dispenser containment underneath new motor 
fuel dispenser systems at UST systems regulated under 40 CFR part 280. 
However, EPA is aware of a small number of dispenser systems, such as 
kerosene dispensers, that do not dispense motor fuel. Small releases 
can occur at these dispensers in the same manner as they occur at motor 
fuel dispensers.15 16 17 Therefore, this final UST 
regulation requires owners and operators install UDC underneath new 
dispenser systems at UST systems regulated under 40 CFR part 280, 
irrespective of whether they dispense motor fuel.

---------------------------------------------------------------------------

    The secondary containment requirement applies to new or replaced 
underground tanks and piping regulated under Subtitle I, except those 
excluded by regulation in Sec.  280.10(b) and those partially excluded 
by regulation in Sec.  280.10(c). Petroleum and hazardous substance 
USTs must meet the secondary containment requirement with the 
corresponding use of interstitial monitoring for release detection. The 
1988 UST regulation allowed variances to the use of interstitial 
monitoring as the method of release detection for hazardous substance 
USTs. Since these variances are no longer an option, EPA is removing 
the language allowing variances for new installations from this final 
UST regulation.
    EPA is requiring owners and operators install tank and piping 
secondary containment that: Will contain regulated substances leaked 
from the primary containment until they are detected and removed; will 
prevent the release of regulated substances to the environment at any 
time during the operational life of the UST system; and is monitored 
for a leak at least once every 30 days using interstitial monitoring. 
These requirements are consistent with the requirements for secondarily 
contained hazardous substance tanks in Sec.  280.42 and are necessary 
to help prevent releases to the environment.
    EPA is not requiring secondary containment for piping that meets 
the requirements of Sec.  280.41(b)(2)(i) through (v), sometimes called 
safe suction piping, because such piping is currently not required to 
meet release detection requirements. Safe suction piping uses a suction 
pump to deliver regulated substances from the UST to the dispenser. 
Safe suction piping operates at less than atmospheric pressure, slopes 
towards the UST so regulated substances drain to the UST if suction is 
lost, and has only one check valve located close to the suction pump. 
As discussed in the 1988 UST regulation preamble, these characteristics 
ensure that little, if any, regulated substances will be released if a 
break occurs in the line.\18\ Similarly, EPA considers piping that 
manifolds two tanks together, which has characteristics that allow 
product to drain to the manifolded tanks if the piping loses suction, 
the same as safe suction piping. In addition, this final UST regulation 
does not require secondary containment for new and replaced piping 
associated with field-constructed tanks greater than 50,000 gallons in 
capacity and airport hydrant fuel distribution systems. See section C-2 
for additional information about these types of UST systems.
---------------------------------------------------------------------------

    \18\ Preamble to 40 CFR part 280, 53 FR 37154, September 23, 
1988.
---------------------------------------------------------------------------

    EPA is not requiring secondary containment and UDC for UST systems 
where installation began on or before 180 days after the effective date 
of this final UST regulation. 180 days allows owners and operators who 
have concrete plans for a new UST system or dispenser installation to 
move forward with their plans before the secondary containment and UDC 
requirement takes effect. Similar to the definition of existing tank 
system in the 1988 UST regulation, EPA considers an installation to 
have begun after the owner or operator applied for or obtained all 
federal, state, and local approvals or permits and:
     Physical construction or installation began; or
     The owner or operator entered into a contractual agreement 
that cannot be cancelled or modified without substantial loss and 
physical construction or installation will commence within a reasonable 
time frame.
    Requiring retrofits of major components would be a significant 
financial burden for owners and operators. EPA anticipates owners and 
operators will replace single walled UST systems as they age. When 
owners and operators replace single walled UST systems after the 
effective date of the final UST regulation, tanks and piping must be 
secondarily contained and new dispensers must have UDC.
    To implement secondary containment and UDC, EPA is adding new 
definitions to this final UST regulation. EPA is defining these terms 
so they are consistent with the definitions contained in EPA's 
secondary containment grant guidelines to implementing agencies.\19\ 
New definitions in the final UST regulation are:
---------------------------------------------------------------------------

    \19\ Grant Guidelines to States for Implementing the Secondary 
Containment Provision of the Energy Policy Act of 2005: https://epa.gov/oust/fedlaws/secondco.htm.
---------------------------------------------------------------------------

     Dispenser--This means equipment located aboveground that 
dispenses regulated substances from the UST system. The 2011 proposed 
UST regulation defined dispenser system. However, based on comments 
received, EPA decided to also add the definition of dispenser to the 
final UST regulation.
     Dispenser system--This means the dispenser and the 
equipment necessary to connect the dispenser to the UST system. As 
described above, EPA decided to add dispenser to the list of 
definitions in the final UST regulation for clarity. As a result, EPA 
shortened the definition of dispenser system in the final UST 
regulation to account for the new definition of dispenser.
     Replaced--For a tank, this means to remove a tank and 
install another tank. For piping, it means to remove 50 percent or more 
of piping and install other piping, excluding connectors, connected to 
a single tank. For tanks with multiple piping runs, this definition 
applies independently to each piping run. Commenters suggested adding a 
definition of replaced as it applies to a dispenser system. However, 
since EPA is only applying the UDC requirement to new dispenser 
systems, we are not defining the term replaced as it relates to 
dispenser systems.
     Secondary containment or secondarily contained--This means 
a release prevention and release detection system for a tank or piping. 
This system has an inner and outer barrier with an interstitial space 
that is monitored for leaks. This term includes containment sumps when 
used for interstitial monitoring of piping. The EPAct defines secondary 
containment as a release

[[Page 41575]]

detection and prevention system that meets the interstitial monitoring 
requirement in Sec.  280.43(g). Based on this definition, this final 
UST regulation includes interstitial monitoring as part of the 
secondary containment definition. Consistent with the 1988 UST 
regulation release detection requirements, EPA is requiring 
interstitial monitoring of new and replaced secondarily contained tanks 
and piping to occur at least once every 30 days. Some commenters 
expressed concern about whether secondary containment included 
containment sumps. To clarify the definition, EPA is adding language 
about containment sumps to the secondary containment definition. In 
addition, EPA is defining containment sump in this final UST 
regulation. See section B-4, Secondary Containment Tests, for details 
about this new definition. Several commenters suggested EPA add to the 
definition of secondary containment a 360 degree containment 
requirement for tanks. EPA relies on codes of practice developed by 
nationally recognized associations or independent testing laboratories 
to determine the degree of containment necessary to be considered 
secondarily contained. This final UST regulation continues to rely on 
these codes of practice for determining when the tanks and piping are 
considered secondarily contained.
     Under-dispenser containment--This means containment 
underneath a dispenser system designed to prevent leaks from the 
dispenser and piping within or above the UDC from reaching soil or 
groundwater. Based on comments received and to provide clarification, 
EPA is adding piping in the containment sump to the definition.
    EPA's secondary containment grant guidelines provide states with 
significant flexibility to define replaced as it applies to piping. The 
guidelines require that states, at a minimum, consider replacing piping 
when 100 percent of piping, excluding connectors, connected to a single 
UST is removed and other piping is installed. When deciding how to best 
define replaced as it applies to piping, EPA analyzed state UST 
regulations for approximately 40 states that currently require 
secondary containment and interstitial monitoring.\20\ About 75 percent 
of these states have requirements as stringent as, or more stringent 
than, the 50 percent threshold in this final UST regulation.

---------------------------------------------------------------------------

    In addition, EPA performed a screening analysis using limited, 
readily available data to determine when repair cost approached 
replacement cost (and at what point owners and operators were most 
likely to replace the entire piping run rather than repair it).\21\ The 
screening analysis suggested replacement cost of an entire piping run 
became equal to repair cost when about 60 percent of a piping run is 
repaired. Since 60 percent was an approximate screening number, EPA in 
this final UST regulation is requiring owners and operators to 
secondarily contain the entire piping run when 50 percent or more of a 
piping run is replaced. Fifty percent represents half of a piping run, 
is consistent with most implementing agency decisions, and provides 
flexibility for allowing repairs while continuing to protect the 
environment. Fifty percent also prevents owners and operators from 
leaving small pipe sections in the ground to avoid this secondary 
containment requirement. If an UST has multiple piping runs, the 
secondary containment requirement applies independently to each piping 
run where 50 percent or more of piping is replaced. Currently installed 
piping runs, and piping runs where less than 50 percent of the piping 
is repaired, do not require secondary containment.
---------------------------------------------------------------------------

    \21\ Industrial Economics Incorporated, Work Assignment #1-19, 
Methodology and Calculator for Secondary Containment for Piping, 
October 3, 2008.
---------------------------------------------------------------------------

    For pressurized piping, EPA considers a piping run to be the piping 
that connects the submersible turbine pump (STP) to all of the 
dispensers fed by that pump. For example, if a tank has two STPs, EPA 
considers the piping associated with each STP to be separate piping 
runs. For suction piping, a piping run is the piping that runs between 
the tank and the suction pump.
    Consistent with EPA's current policy, if an owner or operator 
chooses to reinstall a secondarily contained tank or piping that was 
previously installed, that tank or piping must meet new tank and piping 
standards in Sec.  280.20 at the time of installation.
    EPA is requiring owners and operators install UDC underneath new 
dispenser systems at UST systems regulated by 40 CFR part 280. Data 
from release sites show dispensers are one of the leading release 
sources.22 23 UDC is located underground and prevents some 
releases by containing small leaks that occur inside and underneath the 
dispenser. EPA considers a dispenser system new when owners and 
operators install both the dispenser and equipment needed to connect 
the dispenser to an UST system. EPA includes check valves, shear 
valves, unburied risers or flexible connectors, and other transitional 
components as equipment that connects a dispenser to an UST system. 
This equipment is located underneath the dispenser and typically 
connects underground piping to a dispenser. If an owner or operator 
replaces a dispenser but uses existing equipment to connect a dispenser 
to the UST system, then UDC is not required.

---------------------------------------------------------------------------

    To contain small releases from the dispenser, piping, and other 
equipment, UDC must be liquid tight. This final UST regulation requires 
UDC be liquid tight on its sides, bottom, and at any penetrations 
through the containment. EPA is requiring periodic testing of UDC in 
section B-4, Secondary Containment Tests, if the UDC is used for piping 
interstitial monitoring. In addition, EPA is requiring annual 
inspections of containment sumps in section B-1, Walkthrough 
Inspections, including UDC. Finally, an owner or operator must be able 
to access and visually inspect the containment. If visual inspection 
and access are not possible, then owners and operators must 
periodically monitor UDC (i.e., by electronic monitoring) to ensure it 
is intact and free of liquids. EPA proposed continuous UDC monitoring 
if visual inspection and access of the UDC are not possible. However, 
in guidance to state UST programs about meeting the secondary 
containment provision of the EPAct, EPA did not require continuous 
monitoring. Therefore, to provide owners and operators additional 
flexibility and be consistent with guidance provided to states, this 
final UST regulation requires periodic monitoring of UDC if access to 
and visual inspection of the UDC are not possible.

B. Additional Requirements for Operation and Maintenance

    The 1988 UST regulation required owners and operators install 
improved UST system equipment to detect and prevent releases; however, 
it did not require operation and maintenance for all of that equipment. 
Owners and operators need to properly operate and maintain their UST 
system equipment in order to prevent and quickly detect releases. 
Therefore, this final UST regulation adds requirements for periodic 
walkthrough inspections, spill prevention equipment testing, overfill

[[Page 41576]]

prevention equipment inspections, containment sump testing, and release 
detection equipment testing.
    When a test or inspection occurs, owners and operators may find 
problems with the UST system. When a test or inspection indicates a 
problem, owners and operators must repair the problem to remain in 
compliance with this final UST regulation. Section 280.33 of this final 
UST regulation describes repair requirements for UST systems.
1. Walkthrough Inspections
    To help EPA determine whether walkthrough inspections will be 
effective, EPA asked nine states with requirements for periodic 
walkthrough inspections whether their requirements are effective.\24\ 
Seven states believe their programs are effective. Two states did not 
provide input because they had not been implementing their walkthrough 
inspection programs long enough to evaluate effectiveness. States 
providing input indicated their walkthrough inspections: Identify and 
resolve problems more quickly; decrease the chance of a potential spill 
or release; and increase understanding and compliance with the UST 
regulation. Based on this information and input received from comments 
on the 2011 proposed UST regulation, EPA thinks walkthrough inspections 
will be effective in helping prevent and detect releases.
---------------------------------------------------------------------------

    \24\ Work Order No. 1004, Task 2, Subtask a--State Walkthrough 
Underground Storage Tank Inspections, SKEO, 1/31/2013
---------------------------------------------------------------------------

    Based on comments EPA received, this final UST regulation requires 
owners and operators conduct walkthrough inspections as follows:
     Every 30 days:
    [cir] Visually check spill prevention equipment for damage and 
remove liquid or debris; check for and remove obstructions in the fill 
pipe; check the fill cap to ensure it is securely on the fill pipe; 
and, for double walled spill prevention equipment with interstitial 
monitoring, check for a leak in the interstitial area (exception: 
Owners and operators of spill prevention equipment at UST systems 
receiving deliveries at intervals greater than 30 days may check that 
equipment prior to each delivery)
    [cir] Check release detection equipment to ensure it is operating 
with no alarms or unusual operating conditions present and ensure 
release detection records are reviewed and current
     Annually:
    [cir] Visually check containment sumps for damage and leaks to the 
containment area or releases to the environment; remove liquid (in 
contained sumps) or debris; and, for double walled containment sumps 
with interstitial monitoring, check for a leak in the interstitial area
    [cir] Check hand held release detection equipment, such as 
groundwater bailers and tank gauge sticks, for operability and 
serviceability
    In addition, this final UST regulation allows owners and operators 
to conduct operation and maintenance walkthrough inspections according 
to a standard code of practice developed by a nationally recognized 
association or independent testing laboratory or according to 
requirements developed by the implementing agency. The inspections must 
check equipment in a manner comparable to the walkthrough inspection 
requirements described above.
    This final UST regulation requires owners and operators maintain 
walkthrough inspection records for one year. Most commenters supported 
a one year recordkeeping requirement for walkthrough inspections. In 
addition, the one year recordkeeping time frame is consistent with the 
recordkeeping requirement for 30 day release detection monitoring. The 
walkthrough inspection record must include a list of each area checked, 
whether each area checked was acceptable or needed action taken, a 
description of actions taken to correct an issue, and delivery records 
if owners and operators check spill prevention equipment less 
frequently than every 30 days.
    In 2011, EPA proposed to implement the walkthrough inspection 
requirement on the effective date of the final UST regulation. However, 
based on comments received and to align implementation of all operation 
and maintenance requirements, owners and operators must begin 
conducting walkthrough inspections not later than three years after the 
effective date of this final UST regulation. This change will make 
compliance easier and allow owners and operators ample time to 
understand their walkthrough inspection responsibilities.
    In 2011, EPA proposed requiring owners and operators inspect 
containment sumps once every 30 days. Many commenters were concerned 
about inspecting containment sumps every 30 days because of the 
physical burdens of lifting heavy lids, the potential to ruin seals 
that prevent water from entering the sump, and the safety of the people 
performing the inspection in high traffic areas. While EPA thinks 
frequent containment sump inspections are a valuable part of UST system 
operation and maintenance, EPA recognizes the concerns raised by 
commenters and is moving the requirement to conduct containment sump 
inspections from once every 30 days to annual, which coincides with 
when owners and operators must open containment sumps to test release 
detection equipment.
    In the 2011 proposed UST regulation, EPA required that hand held 
release detection equipment be inspected once every 30 days. Based on 
commenter input, this final UST regulation requires annual inspections 
of hand held release detection equipment to coincide with other release 
detection equipment operation and maintenance requirements.
    In the 2011 proposed UST regulation, EPA required 30 day cathodic 
protection inspections as part of the walkthrough inspection. Several 
commenters indicated this frequency conflicted with the 60 day 
requirement already in the 1988 UST regulation. Based on this input, 
this final UST regulation keeps cathodic protection inspections at the 
60 day interval as required in the 1988 UST regulation. Therefore, 
owners and operators must continue to perform the 60 day impressed 
current cathodic protection inspections to ensure equipment is running 
properly and keep the most recent three records of those inspections.
    The 2011 proposed UST regulation required checking monitoring and 
observation wells every 30 days to make sure they are secure. A few 
commenters questioned the need to perform these inspections because 
owners and operators seldom access these wells unless they are used for 
release detection or cleanup. EPA agrees with these commenters and also 
thinks that owners and operators will secure monitoring wells following 
each 30 day release detection monitoring event or during cleanups as 
part of their normal compliance activities. Therefore, EPA is not 
including monitoring and observation wells as part of the periodic 
walkthrough inspection requirement in this final UST regulation.
    EPA received several comments on the 2011 proposed UST regulation 
recommending treating nonretail UST systems differently than 
traditional commercial UST facilities because some nonretail UST 
systems receive infrequent deliveries. Based on the comments, this 
final UST regulation allows additional flexibility for inspecting spill 
prevention equipment at UST systems where filling occurs infrequently. 
In cases where filling activities occur less often than 30 days, owners 
and operators may inspect spill

[[Page 41577]]

prevention equipment prior to each delivery, instead of at least once 
every 30 days. This exception to the spill prevention equipment check 
for the 30 day walkthrough inspection requirement will still provide 
appropriate environmental protection because the purpose of this 
equipment is to catch drips and spills that may occur when the delivery 
hose is disconnected from the fill pipe. For UST systems receiving 
infrequent deliveries, inspecting spill prevention equipment before 
each delivery is adequate.
    This final UST regulation retains 30 day inspections of release 
detection equipment and spill prevention equipment. EPA thinks these 
inspections are needed at least once every 30 days for release 
detection to ensure the equipment is operating, check release detection 
records, and determine whether the tank or piping is leaking. Owners 
and operators who monitor their release detection system remotely may 
check the release detection equipment and records remotely as long as 
the release detection system at the UST system location is determined 
to be in communication with the remote monitoring equipment. In 
addition, 30 day inspections (or before each delivery) of spill 
prevention equipment will ensure these devices contain small drips and 
spills that occur when the delivery hose is disconnected from the fill 
pipe. Based on commenter input, EPA is adding the requirement to check 
for and remove obstructions in the fill pipe as part of the walkthrough 
inspection because obstructions in the fill pipe will cause a shutoff 
device to operate improperly.
    EPA is including Petroleum Equipment Institute's Recommended 
Practice 900, Recommended Practices for the Inspection and Maintenance 
of UST Systems, as a code of practice that may be used to meet the 
walkthrough inspection requirement in this final UST regulation.\25\ 
This recommended practice includes daily, monthly, and annual 
inspections for properly maintaining underground storage tank systems. 
Owners and operators who use the code of practice option for meeting 
UST requirements must use the entire code of practice. For example, 
owners and operators would not meet the walkthrough inspection 
requirement if they chose to follow only some of the walkthrough 
inspection areas in the code of practice while ignoring others.

---------------------------------------------------------------------------

    This final UST regulation allows flexibility for owners and 
operators to conduct walkthrough inspections themselves or hire a third 
party to conduct walkthrough inspections. Although EPA does not require 
training for owners and operators who conduct these inspections, 
operators trained in the Class A or B training requirements (see 
section A-1) should already have adequate knowledge to perform periodic 
walkthrough inspections.
    EPA received multiple comments suggesting we revise the 30 day 
inspection requirement to be a monthly requirement. After careful 
consideration, EPA is keeping the 30 day inspection requirement. Thirty 
days provides owners and operators with clarity about the inspection 
time frame by specifying the maximum number of days between walkthrough 
inspections. EPA is not moving to monthly inspections because owners 
and operators could misinterpret monthly and go 60 or more days without 
conducting a walkthrough inspection. For example, an owner or operator 
could perform a monthly inspection on January 31, then again on 
February 1, and then not inspect again until March 31. If an owner or 
operator continued this practice, six inspections would occur one day 
apart and six inspections would occur about 60 days apart. While this 
could be considered inspecting monthly, it is not inspecting 
consistently on or about the same time each month. EPA wants to ensure 
the walkthrough inspection frequency is consistent, rather than allow 
the more inconsistent monthly option in this example. Since 30 days is 
the average length of a month, EPA's intent with requiring 30 days is 
to ensure owners and operators conduct walkthrough inspections on or 
about the same time each month.
    Some commenters raised concern about disposing of liquids owners 
and operators discover during the inspection. For spill prevention 
equipment and containment sumps to operate as intended, those areas 
must be free of liquids. In the past, when owners and operators found 
liquids in those areas, they needed to remove the liquids so the 
equipment would operate properly (and meet the 1988 UST regulation). 
This final UST regulation is requiring those areas be inspected 
periodically; as a result, owners and operators may discover the liquid 
sooner, but the responsibility to remove the liquid remains the same. 
EPA expects owners and operators to remove, manage, and dispose of the 
liquid properly (according to federal, state, and local requirements) 
as soon as practicable after discovery.
2. Spill Prevention Equipment Tests
    In this final UST regulation, EPA is adding a three year testing 
requirement for spill prevention equipment. This action helps ensure 
spill prevention equipment will contain small drips and spills when the 
delivery transfer hose is disconnected from the fill pipe. Owners and 
operators need to properly operate and maintain their spill prevention 
equipment in order to prevent releases to the environment. If a small 
release occurs at the fill port and the spill prevention equipment is 
not liquid tight, then the release can exit the spill prevention 
equipment and reach the environment. EPA is aware of various problems 
with spill prevention equipment. Data show that UST spills account for 
about 15 percent of releases from UST systems.26 27 Examples 
of problems with spill prevention equipment include damage due to: 
Vehicles driving over the spill prevention equipment; ground movement 
or freeze and thaw cycles; inadequate installation practices; and 
normal wear and tear. In addition, the typical life of spill prevention 
equipment is relatively short--five to eight years according to a South 
Carolina study.28 29 The life span for spill prevention 
equipment can be even shorter when exposed to more severe weather 
conditions such as freeze and thaw cycles and plowing following snow 
events. Because of these factors, periodic spill prevention equipment 
testing is needed to minimize problems and ensure spill prevention 
equipment will contain small releases from the delivery hose when 
disconnected from the fill pipe.

    This final UST regulation does not require periodic testing of 
double walled spill prevention equipment if the integrity of both walls 
is periodically monitored. Because the integrity of both walls is 
periodically monitored, this type of spill prevention equipment is 
periodically checked for tightness. In 2011, EPA proposed to exclude 
from the periodic testing requirement only double walled spill 
prevention equipment with continuous interstitial monitoring. Several 
commenters suggested that monitoring of the

[[Page 41578]]

interstitial area be used in lieu of periodic spill prevention 
equipment testing. EPA agrees with commenters that double walled spill 
prevention equipment, where the integrity of both walls is periodically 
monitored, should not have to undergo testing--as long as owners and 
operators conduct periodic monitoring of the equipment at a frequency 
consistent with, or more frequent than, the walkthrough inspection 
frequency (see section B-1). For example, owners and operators who 
check vacuum, pressure, or liquid interstitial integrity indicators on 
double walled spill containment devices as part of their 30 day 
walkthrough inspections are considered to be periodically monitoring 
the integrity of both walls.
    For spill prevention equipment that must be tested once every three 
years, this final UST regulation requires owners and operators to 
conduct testing using vacuum, pressure, or liquid methods. In addition, 
the test must be conducted in accordance with manufacturer's 
requirements or a code of practice developed by a nationally recognized 
association or independent testing laboratory. The manufacturer's 
requirement is an option only when the manufacturer has developed 
requirements for testing the tightness of their spill prevention 
equipment. As of the publication date of this final UST regulation, EPA 
is aware of one code of practice that contains procedures for testing 
spill prevention equipment: Petroleum Equipment Institute (PEI) 
Recommended Practice (RP) 1200, Recommended Practices for the Testing 
and Verification of Spill, Overfill, Leak Detection and Secondary 
Containment Equipment at UST Facilities.\30\ EPA is adding this code of 
practice to this final UST regulation. In addition, EPA is providing 
implementing agencies flexibility to allow other methods they determine 
to be as protective of human health and the environment as the 
manufacturer's requirements or a code of practice. This option allows 
alternatives in case codes of practice and manufacturer's requirements 
are not available for testing spill prevention equipment. Several 
commenters expressed concern that EPA did not establish specific pass 
or fail performance criteria for spill prevention equipment testing. 
EPA thinks the manufacturer, code of practice, or implementing agency 
are better suited to establish test method criteria because spill 
prevention devices are manufactured in different shapes and sizes. 
Therefore, EPA is relying on the test method to establish specific pass 
or fail performance criteria.

    In 2011, EPA proposed a one year implementation time frame for 
owners and operators to begin conducting spill prevention equipment 
testing. However, based on commenter input suggesting implementation be 
consistent with other testing requirements, EPA is requiring owners and 
operators of spill containment equipment in use as of the effective 
date of this final UST regulation conduct the first test no later than 
three years after the effective date of this final UST regulation. EPA 
thinks aligning implementation dates for the different operation and 
maintenance testing requirements to the extent possible will provide 
clarity about the requirements owners and operators must meet. After 
the first spill prevention equipment test, owners and operators must 
test spill prevention equipment at least once every three years.
    For UST systems brought into use after the effective date of this 
final UST regulation, the spill prevention equipment testing 
requirement applies at installation. However, owners and operators must 
also follow the installation requirements in Sec.  280.20(d) which 
require manufacturer's instructions and installation standards be 
followed. These instructions and standards currently address liquid 
tightness of spill prevention equipment at installation. As long as the 
spill prevention equipment is tested and liquid tight at installation, 
the first periodic spill prevention equipment test does not have to be 
conducted until three years after installation.
    In 2011, EPA proposed that owners and operators test spill 
prevention equipment at least annually. However, based on comments 
received, EPA is requiring owners and operators test spill prevention 
equipment at least once every three years. Commenters suggested that 
all operation and maintenance testing should be aligned so that all 
tests can be conducted at the same time. EPA agrees. To make it easier 
for owners and operators to comply, this final UST regulation aligns 
periodic spill, overfill, and secondary containment testing to the 
extent possible. Since spill prevention equipment has a relatively 
short lifespan, EPA thinks a three year testing frequency, when 
combined with periodic visual checks via the walkthrough inspection 
(see section B-1), is adequate to ensure spill prevention equipment 
will contain any drips or spills when the delivery hose is disconnected 
from the fill pipe.
    EPA received significant support for requiring owners and operators 
to keep records of the spill prevention equipment test for three years. 
This final UST regulation requires owners and operators maintain 
records of spill prevention equipment testing for three years for each 
spill prevention device at the facility. A three year period aligns 
with the maximum time between on-site UST facility compliance 
inspections. These records will demonstrate to implementing agencies 
that the spill prevention equipment was tested and tight at the time of 
the test.
    Owners and operators of UST systems with double walled spill 
prevention equipment, where the integrity of both walls is periodically 
monitored and who choose not to conduct spill prevention equipment 
testing at least once every three years, must maintain documentation 
showing that spill prevention equipment has two walls and the integrity 
of both walls is periodically monitored. Owners and operators must 
maintain this documentation for as long as the equipment is 
periodically monitored. Owners and operators who discontinue periodic 
monitoring of their double walled spill prevention equipment must 
conduct a test within 30 days of discontinuing the periodic monitoring. 
EPA considers this necessary because discontinuing periodic monitoring 
of the interstitial area may mean some portion of that area of the 
spill prevention equipment may no longer have integrity. Owners and 
operators need to ensure the primary containment of the spill 
prevention equipment is tight. Alternatively, owners and operators may 
choose to test double walled spill prevention equipment once every 
three years, and maintain the test record, in lieu of periodically 
monitoring this equipment and maintaining these monitoring records.
    Several commenters raised concerns about disposal of the spill 
prevention equipment test liquid following the test. EPA considered 
test liquid disposal in this final UST regulation and contacted several 
vendors to determine whether disposal of the test liquid was included 
as part of spill prevention equipment testing.\31\ Some vendors include 
handling of the test liquid as part of the test; they carry the test 
liquid with them and reuse it several times before disposal. Others 
charge a separate cost to dispose of the test liquid or make sure the 
owner or operator has drums on site to dispose of the test liquid. In 
addition,

[[Page 41579]]

vendors sometimes use vacuum testing for spill prevention equipment 
testing, which eliminates the liquid from the test.

Questions and Answers from Three Vendors (11/8/12).
---------------------------------------------------------------------------

    A few commenters raised concerns about facility down time and 
replacement costs for spill prevention equipment as a result of 
testing. EPA acknowledges that, in instances where access to the spill 
prevention equipment is in the line of traffic, there could be a small 
amount of facility down time as a result of testing; however EPA thinks 
the benefit to the environment far outweighs the cost of potential down 
time. To minimize the effects of down time, owners and operators can 
also schedule the testing during low traffic times at the facility or 
when other routine maintenance occurs. EPA expects owners and operators 
to have properly functioning spill prevention equipment at all times 
and fix problems when they are discovered. The spill prevention 
equipment test may uncover a problem earlier, resulting in repair or 
replacement (and better protection from spills) sooner rather than 
later, and more quickly detect or prevent releases of regulated 
substances to the environment.
3. Overfill Prevention Equipment Inspections
    In this final UST regulation, EPA is adding periodic operation and 
maintenance requirements for overfill prevention equipment to help 
ensure the equipment is operating properly and will activate before an 
UST is overfilled. Owners and operators need to properly operate and 
maintain their overfill prevention equipment in order to prevent 
releases to the environment. If overfill prevention equipment is not 
working properly, an UST can be overfilled and release product to the 
environment. EPA is aware that USTs are being overfilled and there are 
problems with overfill prevention equipment. Data show that tank 
overfills account for about 15 percent of releases from UST 
systems.32 33 Examples of problems with overfill prevention 
equipment include: Tampering, improper use, and normal wear and tear. 
Overfill prevention equipment inspections will minimize problems and 
ensure overfill prevention equipment is operating properly.

---------------------------------------------------------------------------

    The 2011 proposed UST regulation used the term testing for overfill 
prevention equipment when describing the periodic functionality checks. 
However, based on input from commenters about potentially overfilling 
the tank during testing, EPA is using the term inspections--rather than 
testing--in this final UST regulation. The procedure to determine 
whether overfill prevention equipment is operating properly should not 
overfill the tank. Rather, the equipment must be inspected to determine 
whether it will operate or activate properly according to requirements 
in this final UST regulation. For example, the inspection to determine 
whether an automatic shutoff device in the fill pipe will activate at 
the correct height might involve removing and inspecting the device to 
ensure it operates as well as measuring the position of the device in 
the tank to ensure it activates at the appropriate level in the tank.
    For overfill prevention equipment inspections, owners and operators 
must use manufacturer's requirements or a code of practice developed by 
a nationally recognized association or independent testing laboratory. 
Manufacturer's requirements are an option only when manufacturers have 
developed inspection requirements for their overfill prevention 
equipment that determines the device is set to activate at the 
appropriate level in the tank and will activate when the regulated 
substance reaches that level. As of this final UST regulation, EPA is 
aware of one code of practice that contains procedures for inspecting 
overfill prevention equipment: PEI RP 1200, Recommended Practices for 
the Testing and Verification of Spill, Overfill, Leak Detection and 
Secondary Containment Equipment at UST Facilities.\34\ EPA added this 
code of practice in this final UST regulation. In addition, EPA is 
providing implementing agencies flexibility to allow other methods they 
determine to be as protective of human health and the environment as 
the manufacturer's requirements or a code of practice. This option 
allows alternatives in case a code of practice and manufacturer's 
requirements are not available for inspecting overfill prevention 
equipment.
---------------------------------------------------------------------------

---------------------------------------------------------------------------

    This final UST regulation requires owners and operators conduct 
overfill prevention equipment inspections at least once every three 
years. Commenters generally supported a three year or more frequent 
inspection cycle. EPA chose the three year time frame because it aligns 
with three year compliance inspections and is consistent with other 
operation and maintenance requirements, such as containment sump 
testing and spill prevention equipment testing.
    In 2011, EPA proposed to stagger implementation for overfill 
prevention equipment inspections over a three year period based on the 
installation date of the oldest UST at the facility. However, EPA 
received significant input from commenters opposing the phased in 
approach and advocating a single implementation date. EPA agrees with 
the merits of a more simplified approach. Therefore, for overfill 
prevention equipment installed as of this final UST regulation, owners 
and operators must conduct the first inspection within three years of 
the effective date of this final UST regulation. After the first 
overfill prevention equipment inspection, owners and operators must 
inspect overfill prevention equipment at least once every three years.
    For UST systems brought into use after the effective date of this 
final UST regulation, the overfill prevention equipment inspection 
requirement applies at installation. However, owners and operators must 
also follow the installation requirements in Sec.  280.20(d) which 
require following manufacturer's instructions and installation 
standards. These instructions and standards currently address the 
operability of the overfill equipment at installation. As long as the 
overfill prevention equipment is inspected for operability at 
installation, the first periodic overfill prevention equipment 
inspection does not have to be conducted until three years after 
installation.
    EPA received significant support for requiring owners and operators 
to keep records of overfill prevention equipment inspections for three 
years. The three year period aligns with the maximum time between on-
site UST facility compliance inspections. Therefore, this final UST 
regulation requires owners and operators maintain for three years 
overfill prevention equipment inspection records for each overfill 
device at the facility. These records will demonstrate to implementing 
agencies that the overfill prevention equipment has been inspected, is 
set at the appropriate height in the tank, and will activate when 
regulated substances reach that height.
    Several commenters were concerned about potential damage to 
overfill prevention equipment during removal for inspection. EPA asked 
several vendors who perform overfill prevention equipment inspections 
about the potential for damage during periodic overfill prevention 
equipment

[[Page 41580]]

inspections.\35\ The vendors indicated that seals may need to be 
replaced when removing the equipment, but that overfill prevention 
equipment itself would not easily be damaged during removal or 
reinstallation. The vendors also indicated that replacing these seals 
will result in little or no additional cost to the owner and operator.

Questions and Answers from Three Vendors (11/8/12).
---------------------------------------------------------------------------

    A few commenters raised concerns about facility down time and 
replacement costs for overfill prevention equipment as a result of 
periodic inspections. EPA acknowledges that, in instances where access 
to overfill prevention equipment is in the line of traffic, there could 
be a small amount of facility down time as a result of inspecting; 
however EPA thinks the benefit to the environment far outweighs the 
cost of potential down time. To minimize the effects of down time, 
owners and operators can also schedule the inspection during low 
traffic times at the facility or when other routine maintenance occurs. 
EPA expects owners and operators to have properly functioning overfill 
prevention equipment at all times and fix problems when they are 
discovered. The overfill prevention equipment inspection may uncover a 
problem earlier, resulting in repair or replacement (and better 
protection from overfills) sooner rather than later.
4. Secondary Containment Tests
    The 2011 proposed UST regulation included periodic secondary 
containment testing requirements for secondary containment areas of 
tanks and piping and for containment sumps used for monitoring the 
secondary containment areas of piping. However, based on the 
significant opposition commenters provided, this final UST regulation 
is not requiring periodic secondary containment testing of secondarily 
contained tanks and piping. EPA agrees with commenters who indicated 
secondarily contained UST systems using interstitial monitoring are 
more protective of the environment than single walled UST systems. In 
addition, EPA understands that some secondarily contained UST systems 
installed before this final UST regulation may not have been designed 
to have the interstitial areas periodically tested. Finally, EPA does 
not want to create a disincentive for owners and operators to replace 
older single walled UST systems with secondarily contained systems or 
penalize early installers of secondarily contained UST systems. 
However, this final UST regulation does require testing of these areas 
following a repair or, as appropriate, in response to a suspected 
release if they are used for interstitial monitoring. Interstitial 
areas where interstitial monitoring is used need to be tight following 
a repair so that the interstitial monitoring will detect a release 
before it reaches the environment. Likewise, interstitial areas need to 
be tested in response to a suspected release to determine whether a 
leak has reached the environment.
    EPA disagrees with commenters who suggested periodic testing for 
containment sumps used for interstitial monitoring of piping is 
unnecessary. These areas function similar to spill containment 
equipment, containing leaks from piping and other components in the 
sump. Containment sumps can degrade over time, resulting in releases to 
the environment. Information about source and cause of release shows 
that a significant number of releases occur in containment sump 
areas.36 37 Containment sumps have piping and other 
components that penetrate through the containment sump walls, 
increasing the likelihood that these areas are not liquid tight. 
Containment sumps used for interstitial monitoring of piping need to be 
liquid tight so they will contain regulated substances released from 
the primary wall of the piping. Therefore, this final UST regulation 
includes a three year testing requirement for containment sumps used 
for interstitial monitoring of piping.

---------------------------------------------------------------------------

    This final UST regulation does not require periodic testing of 
double walled containment sumps used for interstitial monitoring of 
piping if the integrity of both walls of the containment sump is 
periodically monitored. Because the integrity of both walls is 
periodically monitored, this type of containment sump is periodically 
checked for tightness. EPA proposed to exclude from the periodic 
testing requirement only containment sumps with continuous interstitial 
monitoring. Several commenters suggested that periodic monitoring 
(rather than continuous monitoring) of the interstitial area of the 
double walled containment sump would be adequate in lieu of performing 
the periodic containment sump testing. EPA agrees with commenters that 
double walled containment sumps, where the integrity of both walls is 
periodically monitored, should not have to undergo testing--as long as 
owners and operators conduct periodic monitoring of the equipment at a 
frequency consistent with, or more frequent than, the walkthrough 
inspection frequency (see section B-1). For example, owners and 
operators who check vacuum, pressure, or liquid interstitial integrity 
indicators on double walled containment sumps as part of their annual 
walkthrough inspections are considered to be periodically monitoring 
the integrity of both walls.
    This final UST regulation does not require periodic testing of 
containment sumps used for reasons other than interstitial monitoring 
of piping. Testing of these areas is not necessary to ensure the 
release detection will detect a leak because owners and operators are 
not using the containment sumps for interstitial monitoring. In these 
cases, owners and operators use another method of release detection and 
previously installed containment sumps as part of good business 
practice.
    Some commenters suggested EPA add definitions for continuous 
monitoring and interstitial monitoring. Since this final UST regulation 
uses the concept of periodic monitoring rather than continuous 
monitoring, EPA is not defining continuous monitoring. The concept of 
interstitial monitoring was used in the 1988 UST regulation and remains 
the same in this final UST regulation (see Sec.  280.43(g)). In 
addition, this final UST regulation describes interstitial monitoring 
in detail in subpart D. Therefore, EPA is not further defining 
interstitial monitoring. Based on commenter input, EPA is adding to 
this final UST regulation a definition of containment sump, which 
addresses comments about what constitutes a containment sump. EPA 
considers a containment sump to be a liquid tight container that 
protects the environment by containing leaks and spills of regulated 
substances from piping, dispensers, pumps, and related components in 
the containment area. Containment sumps may be single walled or 
secondarily contained and located at the top of tank (tank top or 
submersible turbine pump sump), underneath the dispenser (under-
dispenser containment sump), or at other points in the piping run 
(transition or intermediate sump).
    This final UST regulation requires owners and operators conduct 
testing of containment sumps used for interstitial monitoring of piping 
at least once every three years. Commenters generally supported a three 
year or more frequent inspection cycle. EPA is choosing the three year 
time frame to: Make

[[Page 41581]]

compliance easier for owners and operators; align with three year 
compliance inspections; and be consistent with other operation and 
maintenance requirements, such as overfill prevention equipment 
inspections and spill prevention equipment testing.
    For containment sumps that require testing at least once every 
three years, this final UST regulation requires owners and operators 
conduct testing by using vacuum, pressure, or liquid methods. In 
addition, the test must be conducted in accordance with manufacturer's 
requirements or a code of practice developed by a nationally recognized 
association or independent testing laboratory. The manufacturer's 
requirement is an option only when the manufacturer has developed 
testing requirements for their containment sumps that ensure their 
containment sump is tight. As of this final UST regulation, EPA is 
aware of one code of practice that contains procedures for testing 
containment sumps: PEI RP 1200, Recommended Practices for the Testing 
and Verification of Spill, Overfill, Leak Detection and Secondary 
Containment Equipment at UST Facilities, and is adding this code of 
practice to the final UST regulation.\38\ In addition, EPA is providing 
implementing agencies flexibility to allow other methods they determine 
to be as protective of human health and the environment as the 
manufacturer's requirements or a code of practice. This option allows 
alternatives in the event that a code of practice and manufacturer's 
requirements are not available for testing containment sumps. Several 
commenters expressed concern that EPA did not establish specific pass 
or fail performance criteria for containment sump testing. However, EPA 
thinks the test method established by the manufacturer, code of 
practice, or implementing agency are better suited to establish 
criteria because containment sumps are made in different shapes and 
sizes. Therefore, EPA is relying on the test method to establish 
specific pass or fail performance criteria.

    In 2011, EPA proposed to stagger secondary containment testing 
implementation over a three year period, based on the installation date 
of the oldest UST at a facility. However, EPA received significant 
input from commenters opposing a phased in approach and advocating a 
single implementation date. EPA agrees with the merits of a more 
simplified approach. Therefore, containment sumps used for interstitial 
monitoring of piping installed as of the effective date of this final 
UST regulation must be tested within three years of the effective date 
of this final UST regulation. After the first test, owners and 
operators must conduct periodic testing at least once every three 
years.
    For UST systems brought into use after the effective date of this 
final UST regulation, the containment sump testing requirement applies 
at installation. However, owners and operators must also follow the 
installation requirements in Sec.  280.20(d) which require following 
manufacturer's instructions and installation standards. These 
instructions and standards currently address liquid tightness of 
containment sumps at installation. As long as the containment sump is 
tested and liquid tight at installation, the first periodic containment 
sump test does not have to be conducted until three years after 
installation.
    EPA received significant support for the three year recordkeeping 
time frame for secondary containment testing because the three year 
time period aligns with the maximum time between on-site UST facility 
compliance inspections. Therefore, this final UST regulation requires 
owners and operators maintain for three years containment sump testing 
records for each containment sump used for interstitial monitoring at a 
facility. These records will demonstrate to implementing agencies that 
containment sumps were tested and tight at the time of the test.
    Owners and operators who have double walled containment sumps where 
the integrity of both walls is periodically monitored and choose not to 
conduct containment sump testing at least once every three years must 
maintain documentation showing their containment sumps have two walls 
and the integrity of both walls is periodically monitored. Owners and 
operators must maintain this documentation for as long as the integrity 
of the two walls of the containment sump is periodically monitored. 
Owners and operators who discontinue periodic monitoring of their 
double walled containment sumps must conduct a test within 30 days of 
discontinuing the periodic monitoring. EPA considers this necessary 
because discontinuing periodic monitoring of the interstitial area may 
mean some portion of that area of the containment may no longer have 
integrity. Therefore, owners and operators need to ensure the primary 
containment of the containment sump is tight. Alternatively, owners and 
operators may choose to test double walled containment sumps (and 
maintain testing records) once every three years in lieu of maintaining 
these records.
    Several commenters raised concern about disposing of containment 
sump test liquid following the test. EPA considered test liquid 
disposal in this final UST regulation and contacted several vendors to 
determine whether they included disposal of test liquid as part of 
containment sump testing.\39\ Some vendors include handling of the test 
liquid as part of the test; they carry the test liquid with them and 
reuse it several times before disposal. Others charge a separate cost 
to dispose of the test liquid or make sure the owner or operator has 
drums on site to dispose of the test liquid. In addition, vendors could 
use vacuum testing for containment sump testing, which eliminates the 
liquid from the test.

Questions and Answers from Three Vendors (11/8/12).
---------------------------------------------------------------------------

    A few commenters raised concerns about facility down time and 
replacement costs for containment sumps as a result of testing. EPA 
acknowledges that, in instances where access to the containment sump is 
in the line of traffic, there could be a small amount of facility down 
time as a result of testing; however EPA thinks the benefit to the 
environment far outweighs the cost of potential down time. To minimize 
the effects of down time, owners and operators can also schedule the 
testing during low traffic times at the facility or when other routine 
maintenance occurs that requires opening containment sumps. EPA expects 
owners and operators to have properly functioning containment sumps at 
all times when those containment sumps are used for interstitial 
monitoring of piping and fix problems when they are discovered. The 
containment sump test may uncover a problem earlier than if a test was 
never conducted, resulting in repair or replacements of the containment 
sump (and better protection from releases) sooner rather than later.
5. Release Detection Equipment Tests
    This final UST regulation requires UST owners and operators perform 
annual operation and maintenance tests on electronic and mechanical 
components of their release detection equipment to ensure the equipment 
is operating properly. Owners and operators are required, at a minimum, 
to check this equipment:


[[Page 41582]]


 Automatic tank gauge (ATG) systems and other controllers
    [cir] Test alarm
    [cir] Verify system configuration
    [cir] Test battery back-up
 Probes and sensors
    [cir] Inspect for residual build-up
    [cir] Ensure floats move freely
    [cir] Ensure shaft is not damaged
    [cir] Ensure cables are free of kinks and breaks
    [cir] Test alarm operability and communication with controller
 Automatic line leak detector (ALLD)
    [cir] Simulate leak which determines capability to detect a leak
 Vacuum pumps and pressure gauges
    [cir] Ensure proper communication with sensors and controller
 Handheld electronic sampling equipment associated with vapor 
and groundwater monitoring
    [cir] Ensure proper operation

    This final UST regulation changes some requirements discussed in 
the 2011 proposed operation and maintenance for release detection 
equipment requirements. Changes include:

 Noting that PEI RP 1200 may be used to meet the testing 
requirements
 Increasing from one year to three years the time allowed for 
UST system owners and operators to implement the requirements
 Using the term automatic line leak detector instead of line 
leak detector
 Removing the leak sensing O-ring from the list of components 
tested
 Adding handheld electronic equipment associated with vapor and 
groundwater monitoring

    EPA is concerned about the performance of release detection 
equipment. Inspectors routinely find release detection equipment 
installed on UST systems, but often that equipment is not properly 
operated or maintained. In addition, information from an analysis in 
Florida indicates that leak detection successfully detected 26 percent 
of all releases. Conversely, leak detection was specifically identified 
as failing to detect 23 percent of releases.\40\ To increase the 
effectiveness of release detection, this final UST regulation targets 
operation and maintenance.
---------------------------------------------------------------------------

    \40\ Petroleum Releases At Underground Storage Tank Facilities 
In Florida, Peer Review Draft, US EPA-OUST, March 2005.
---------------------------------------------------------------------------

    This final UST regulation requires that release detection is 
operated and maintained in accordance with manufacturer's instructions, 
a code of practice, or requirements developed by the implementing 
agency. To achieve optimal performance from equipment and to meet 
release detection requirements, it is important for UST system owners 
and operators to both install the equipment properly and properly 
operate and maintain it. In the 1988 UST regulation, EPA did not 
provide specifics on the minimum requirements to ensure adequate 
operation and maintenance of release detection equipment. As a result, 
manufacturer operation and maintenance requirements vary greatly, even 
among similar types of equipment.
    Some manufacturer's requirements do not adequately address 
operation and maintenance. For example, some manufacturers only 
recommend operation and maintenance testing; but EPA is taking the 
position that testing should be mandatory instead of optional. In 
addition, similar release detection components should be tested in a 
similar manner, which will increase the likelihood all release 
detection equipment will function at optimal levels for as long as 
possible. California's in field analysis of sensors used for release 
detection supports EPA's position.\41\

---------------------------------------------------------------------------

    This final UST regulation improves and standardizes operation and 
maintenance for all release detection equipment; it provides owners and 
operators with required equipment tests, which will help ensure 
equipment is properly operated and maintained. EPA is requiring a set 
of minimum operation and maintenance criteria that owners and operators 
must follow for electronic and mechanical based release detection 
equipment.
    The operation and maintenance minimum requirements for release 
detection established in This final UST regulation are based on common 
requirements and recommendations by various equipment manufacturers of 
similar equipment. EPA used the National Work Group On Leak Detection 
Evaluations' (NWGLDE) list of leak detection equipment to identify 
commonly used equipment.\42\ In addition, EPA's publication, Operating 
And Maintaining Underground Storage Tanks Systems: Practical Help And 
Checklists and PEI's Recommended Practices for the Inspection and 
Maintenance of UST Systems (RP 900) also helped establish proper 
operation and maintenance activities.

---------------------------------------------------------------------------

    Owners and operators must meet the release detection operation and 
maintenance requirements according to one of the following: 
Manufacturer's instructions; a code of practice developed by a 
nationally recognized association or independent testing laboratory; or 
requirements determined by the implementing agency to be no less 
protective of human health and the environment than the two options 
listed above. These requirements are consistent with options for other 
operation and maintenance activities in this final UST regulation. As 
an example, see section B-2, Spill Prevention Equipment Tests.
    At the time of the 2011 proposed UST regulation, PEI was developing 
a code of practice, which EPA anticipated would address operability 
testing of release detection equipment. PEI issued the final 
recommended practice in 2012. EPA reviewed PEI's final Recommended 
Practices for the Testing and Verification of Spill, Overfill, Leak 
Detection and Secondary Containment Equipment at UST Facilities (RP 
1200) and is including it in this final regulation as an option for 
meeting the annual release detection equipment testing 
requirements.\43\
---------------------------------------------------------------------------

    \43\ This document is available for purchase at www.pei.org.
---------------------------------------------------------------------------

    This final UST regulation requires owners and operators maintain 
records of the annual operation tests for three years. At a minimum, 
records must: List each component tested; indicate whether each 
component meets the criteria listed or needed to have action taken; and 
describe any action taken to correct an issue. The requirement to 
maintain records for three years is consistent with the three year 
compliance inspection cycle; maintaining records will allow owners and 
operators to demonstrate compliance with this operation and maintenance 
requirement.
    Based on comments received and EPA's goal to align all 
implementation dates for consistency and easier compliance, this final 
UST regulation requires owners and operators meet operation and 
maintenance for release detection requirements no later than three 
years after the effective date of the final UST regulation. This is a 
change from the 2011 proposed UST regulation, which required that 
owners and operators meet this requirement no later than one year after 
the effective date of the final UST regulation.
    The 2011 proposed UST regulation used the term line leak detector 
as a component that must be tested. Based on comments received, this 
final UST regulation uses the term automatic line leak detector. This 
is consistent with

[[Page 41583]]

how EPA has historically referenced line leak detectors in the 1988 UST 
regulation. These devices can be electronic or mechanical and are 
described in Sec.  280.44(a). Commenters also asked EPA to add the 
performance criteria of 3 gallons per hour at 10 pounds per square inch 
line pressure to the simulated ALLD test required for the line leak 
detector. This is unnecessary since the 2011 proposed UST regulation 
required this performance standard for the simulated test by 
referencing Sec.  280.44(a). This final UST regulation maintains that 
ALLDs, whether electronic or mechanical, must meet the annual simulated 
leak test of 3 gallons per hour at 10 pounds per square inch line 
pressure within 1 hour.
    One commenter noted his experience with testing release detection 
equipment, which verified electrical circuitry, but during operation 
the connected device still did not function to its intended precision. 
This commenter recommended EPA change the term test to functionality 
test. EPA thinks this change is unnecessary. The operation and 
maintenance requirements for release detection feature minimum 
performance criteria for testing. Each method used to meet the 
requirement (manufacturer's instructions, a code of practice, or 
requirements developed by the implementing agency) must, at a minimum, 
cover each listed component and the stated performance criteria.
    EPA disagrees with the commenter who said EPA should allow self-
diagnostic equipment. Similar to the commenter in the previous 
paragraph, EPA is concerned that self-diagnostic equipment might verify 
electrical circuitry or communication, but not actually test equipment 
functionality. EPA requires testing to be performed in a manner that 
verifies equipment operation according to performance standards 
provided for each piece of release detection equipment. For example, 
testing ALLDs must involve simulating a system leak not greater than 3 
gallons per hour at 10 pounds per square inch line pressure within 1 
hour, or equivalent. ALLDs connected to ATG systems or other 
controllers may themselves be used to test electronic communication, 
but unless capable of simulating an appropriate leak in the system, do 
not meet the performance standard and, therefore, cannot be used to 
meet this requirement.
    In this final UST regulation, EPA is deleting language from the 
2011 proposed UST regulation about inspecting and testing the leak 
sensing O-ring. Commenters requested EPA clarify what a leak sensing O-
ring is. This O-ring is specific to the functional element of 
mechanical line leak detectors and is, therefore, only present on 
certain types of ALLDs. In addition, all functional elements will be 
tested as part of the simulated leak test conducted at 3 gallons per 
hour at 10 psi or equivalent for all ALLDs.
    This final UST regulation allows use of groundwater and vapor 
monitoring as methods of release detection, but with some restrictions 
(see section D-6). For owners and operators choosing groundwater or 
vapor monitoring as their method of release detection, this final UST 
regulation requires that hand held electronic devices such as 
photoionization devices meet the operation and maintenance requirements 
for release detection equipment. Non electronic hand held devices, such 
as measuring sticks and groundwater bailers, are covered in section B-
1, Walkthrough Inspections.

C. Addressing Deferrals

    This final UST regulation addresses airport hydrant fuel 
distribution systems and USTs with field-constructed tanks. In 
addition, this final UST regulation removes the release detection 
deferral for UST systems that store fuel solely for use by emergency 
power generators. As a result, these UST systems may no longer be 
subject to Spill Prevention, Control, and Countermeasure (SPCC) 
requirements. Finally, this final UST regulation partially excludes 
from Part 280 requirements wastewater treatment tank systems, UST 
systems containing radioactive material regulated under the Atomic 
Energy Act, and UST systems that are part of an emergency generator 
system at nuclear power generation facilities regulated by the Nuclear 
Regulatory Commission under 10 CFR part 50. To the extent these systems 
were regulated by the SPCC requirements, they will continue to be 
regulated by those requirements.
    In this final UST regulation, EPA partially excludes from part 280 
requirements the aboveground storage tanks associated with airport 
hydrant fuel distribution systems and USTs with field-constructed 
tanks. These aboveground storage tanks are part of the UST system, but 
are excluded from most of this final UST regulation because they are 
not underground. At the time of the 1988 UST regulation, facilities 
with an aggregate completely buried storage capacity greater than 
42,000 gallons and located near navigable waters of the United States 
or adjoining shorelines were subject to both UST regulations and SPCC 
regulations. Since then, the SPCC regulation has been amended and 
exempts completely buried storage tanks, as well as connected 
underground piping, underground ancillary equipment, and containment 
systems when fully subject to the technical requirements of 40 CFR part 
280. Partially excluded aboveground storage tanks which are part of the 
UST system may be subject to SPCC requirements.
1. UST Systems Storing Fuel Solely for Use by Emergency Power 
Generators--Require Release Detection
    This final UST regulation eliminates the deferral for UST systems 
storing fuel solely for use by emergency power generators (also 
referred to as emergency generator tanks). This means emergency 
generator tanks are no longer deferred from release detection 
requirements in 40 CFR part 280, subpart D and are subject to all UST 
requirements.
    This final UST regulation requires owners and operators of UST 
systems storing fuel solely for use by emergency power generators begin 
meeting these requirements:

 For systems installed after the effective date of this final 
UST regulation, at the time of installation
     For systems installed on or before the effective date of 
this final UST regulation, within three years of the effective date of 
this final UST regulation

    EPA is regulating UST systems storing fuel solely for use by 
emergency power generators because the rationale in the 1988 UST 
regulation for deferring release detection no longer applies. To allow 
time for developing workable release detection requirements, EPA in the 
1988 UST regulation deferred release detection requirements for UST 
systems storing fuel solely for use by emergency power generators. The 
1988 UST regulation preamble indicated that monthly monitoring 
requirements were unworkable because these tanks often were located at 
unmanned stations in remote areas and visited infrequently.
    EPA always intended for these systems to meet release detection 
requirements when appropriate release detection methods became 
available. Since the 1988 UST regulation, release detection 
technologies have matured greatly. In addition, technology is now 
available to perform release detection at remote sites. Emergency 
generator tanks can now be monitored for releases by the majority of 
methods listed in subpart D. EPA estimates about 30 percent of 
emergency generator tanks already have release detection.
    Effective remote monitoring methods for release detection are now 
available

[[Page 41584]]

and currently used to monitor unmanned UST systems storing fuel solely 
for emergency generator tanks. Numerous companies perform remote 
monitoring for releases at these unmanned sites. When there is a 
suspected release, a remote monitor transmits a visual or audible alarm 
to a receiving console at a manned location. This provides owners and 
operators with real-time release detection data so owners and operators 
can quickly respond to suspected releases at sites with unmanned 
emergency generator tanks.
    Several commenters raised concerns that release detection methods 
may not properly operate on some emergency generator tanks and 
suggested changes to the release detection requirement. Commenters 
reported these issues:

 Looped piping systems, which is piping configured to run 
continuously with integrated supply and return lines, cannot be 
properly isolated or does not have a sufficient quiet period to perform 
a precision test when using automatic tank gauging
 Emergency generator tanks with copper piping may pose issues 
with meeting the release detection requirement due to system 
configurations
 Most emergency generator tanks are single walled and are 
limited to automatic tank gauging as the form of release detection
 Emergency generator tanks with day tanks and aboveground 
piping may need anti-siphon valves

    Other commenters suggested EPA limit the type of release detection, 
such as statistical inventory reconciliation (SIR), owners and 
operators may use on emergency generator tanks and that EPA should 
require owners and operators install electronic line leak detectors, 
which have a positive system shutdown of any product flow in the event 
of a leak. Other commenters recommended EPA clarify that automatic line 
leak detectors can go to alarm mode only and not shut down or restrict 
product flow when a leak is suspected in emergency generator tanks used 
during a crisis.
    EPA agrees that not all release detection methods may be suitable 
for all configurations of emergency generator tanks. EPA discussed the 
applicability of SIR on emergency generator tanks in general with 
several SIR vendors and received conflicting responses. A challenge to 
performing release detection is establishing a usage rate of product 
based on the run time of the system during operation. Although EPA 
thinks it is difficult to achieve accurate results, we do not have 
enough information at this time to determine that SIR or other methods 
that rely on metered data are unacceptable for use on emergency 
generator tanks. Owners and operators must carefully consider whether 
these methods meet the release detection requirement for their UST 
systems. To meet the release detection requirement, some systems may 
require reconfiguration and addition of components such as anti-siphon 
valves to separate sections of the system. Some emergency generator 
tanks use safe suction piping, in which case release detection for 
piping is not required. However, release detection technologies have 
advanced since EPA issued the 1988 UST regulation and there are now 
various options available to meet this requirement. EPA understands 
some commenters want to require owners and operators to install 
automatic line leak detectors, which only shut off at the STP or 
allowing only certain release detection methods for these systems. 
However, to provide flexibility to owners and operators while 
continuing to protect human health and the environment, this final UST 
regulation allows owners and operators to choose the most appropriate 
release detection methods, including automatic line leak detectors that 
trigger an alarm only and not necessarily shut down the pump, for their 
systems. For an unmanned facility, the alarm must be transmitted to a 
monitoring center where someone can hear or see the alarm and quickly 
respond to a suspected release.
    One commenter suggested EPA define what is mission critical as it 
relates to emergency generator tanks. While EPA acknowledges the need 
for operating emergency generator tanks during an emergency, we think 
it is unnecessary to define the term mission critical or make 
exceptions for the release detection requirement for these tanks. The 
concern is that owners and operators of these systems should not have 
to shut down their systems during an emergency if they encounter a 
suspected release. EPA understands this concern but thinks owners and 
operators can perform release detection and respond to suspected 
releases while continuing to operate the UST system.
    Emergency generator tanks are located throughout the country. EPA's 
review of several state databases revealed these systems are located at 
hospitals, universities, communication utilities, military 
installations, and other locations relying on backup power sources. 
Based on information from these databases, EPA estimates UST systems 
storing fuel solely for use by emergency power generators represent 
approximately 3 percent of the active tank population.
    Additionally, about 20 states currently require release detection 
for emergency generator tanks. Automatic tank gauging and secondary 
containment with interstitial monitoring are the most common release 
detection methods used for emergency generator tanks. Line tightness 
testing, automatic line leak detectors, or secondary containment with 
interstitial monitoring are the most common release detection methods 
used for piping. With technology now available to detect releases from 
emergency generator tanks and because they pose a risk to human health 
and the environment, this final UST regulation removes the deferral 
from release detection.
    The 2011 proposed UST regulation required owners and operators meet 
the release detection requirement within one year of the effective date 
of the final UST regulation. Several commenters raised concerns that a 
one-year time frame to meet this requirement is insufficient for owners 
and operators to assess, budget, and install release detection. 
Commenters also wanted EPA to establish a single implementation date, 
which is consistent with effective dates for release detection on other 
previously deferred tanks. EPA agrees that extending the time frame 
will allow owners and operators sufficient time for planning and 
installing necessary equipment to meet the release detection 
requirement; but we disagree with commenters who suggested a five to 
ten year implementation date. EPA also agrees that establishing a 
single effective date, which is consistent with other effective dates 
for the release detection requirement, decreases the tracking burden on 
implementing agencies as well as owners and operators. Based on support 
for increasing the final implementation date for release detection from 
one year and EPA's goal of aligning regulatory implementation dates to 
make compliance easier for owners and operators, EPA is requiring 
owners and operators of emergency generator tanks installed on or 
before the effective date of this final UST regulation to meet the 
release detection requirement within three years of the effective date 
of this final UST regulation. Emergency generator tanks installed after 
the effective date of this final UST regulation must meet the release 
detection requirements when installed.
    The 2011 proposed UST regulation required that no later than 30 
days after the effective date of the final UST regulation, owners of 
UST systems storing fuel solely for use by emergency

[[Page 41585]]

power generators notify implementing agencies that their systems exist. 
Commenters stated that this requirement is unnecessary because the 1988 
UST regulation excluded emergency generator tanks from only the release 
detection requirement. EPA agrees with commenters. This final UST 
regulation does not include this one-time notification requirement for 
emergency generator tanks.
2. Airport Hydrant Fuel Distribution Systems and UST Systems With 
Field-Constructed Tanks
    This final UST regulation removes the 1988 deferral and requires 
owners and operators of airport hydrant fuel distribution systems 
(referred to as airport hydrant systems) comply with applicable 
requirements. However, EPA is tailoring the requirements to the unique 
nature of airport hydrant systems. Airport hydrant systems function and 
are designed differently than conventional USTs. Unlike conventional 
USTs, airport hydrant systems consist of networks of large diameter 
underground piping operating at high pressures to deliver fuel to 
aircraft. In addition, operation and maintenance requirements for 
airport hydrant systems may differ from those for conventional UST 
systems.
    This final UST regulation removes the 1988 deferral and requires 
owners and operators of UST systems with field-constructed tanks comply 
with applicable requirements. Similar to airport hydrant systems, EPA 
is tailoring the requirements to the unique nature of field-constructed 
tanks. UST systems with field-constructed tanks (referred to as field-
constructed tanks) range from conventional sizes to very large 
capacities greater than 2 million gallons.
    A few commenters suggested EPA write regulations specifically for 
airport hydrant systems and field-constructed tanks, since they are 
distinctly different from conventional USTs. EPA agrees that airport 
hydrant systems and field-constructed tanks are different from 
conventional USTs. Additionally, EPA thinks it would help owners and 
operators if the requirements for airport hydrant systems and field-
constructed tanks are in a separate subpart of the final UST 
regulation. In order to help owners and operators of these systems 
comply, this final UST regulation adds subpart K (UST Systems with 
Field-Constructed Tanks and Airport Hydrant Fuel Distribution Systems) 
and places most regulatory requirements for both airport hydrant 
systems and field-constructed tanks in one location. Since 1988, owners 
and operators of these systems have been required to comply with the 
requirements for subparts A (Program Scope and Interim Prohibition) and 
F (Release Response and Corrective Action for UST Systems Containing 
Petroleum or Hazardous Substances).
    This final UST regulation requires airport hydrant systems and 
field-constructed tanks installed on or before the effective date of 
the final UST regulation begin meeting the requirements of subpart K 
according to the schedule below. Airport hydrant systems and field-
constructed tanks installed after the effective date of this final UST 
regulation must meet the requirements at the time of installation.

------------------------------------------------------------------------

    This final UST regulation modifies the 2011 proposed UST regulation 
by revising the definition of airport hydrant fuel distribution system 
and defining a field-constructed tank.
    An airport hydrant fuel distribution system (also called airport 
hydrant system) is defined as an UST system which fuels aircraft and 
operates under high pressure with large diameter piping that typically 
terminates into one or more hydrants (fill stands). The airport hydrant 
system begins where fuel enters one or more tanks from an external 
source, such as a pipeline, barge, rail car, or other motor fuel 
carrier.
    A field-constructed tank is defined as a tank constructed in the 
field. For example, a tank constructed of concrete that is poured in 
the field, or a steel or fiberglass tank primarily fabricated in the 
field is considered field-constructed.
Overview of Actions
Release Detection--Tanks
    This final UST regulation requires airport hydrant system tanks and 
field-constructed tanks meet these requirements:
     These tanks must be monitored using release detection 
methods specified in subpart D:
    [cir] Shop fabricated tanks and
    [cir] Field-constructed tanks with a capacity less than or equal to 
50,000 gallons
     Field-constructed tanks with a capacity greater than 
50,000 gallons must either be monitored using release detection methods 
specified in subpart D (except tanks using groundwater and vapor 
monitoring must combine that method with inventory control as described 
in the alternatives below) or use one of the alternatives below
    [cir] Conduct an annual tank tightness test that can detect a 0.5 
gallon per hour (gph) leak rate
    [cir] At least once every 30 days, use an automatic tank gauging 
system to perform release detection, which can detect a leak rate of 1 
gallon per hour or less; and at least once every three years, use a 
tank tightness test that can detect a 0.2 gallon per hour leak rate
    [cir] At least once every 30 days, use an automatic tank gauging 
system to perform release detection, which can detect a leak rate of 2 
gallons per hour or less; and at least every two years, use a tank 
tightness test that can detect a 0.2 gallon per hour leak rate
    [cir] At least every two years, perform vapor monitoring (conducted 
according to Sec.  280.43(e) for a tracer compound placed in the tank 
system) capable of detecting a 0.1 gallon per hour leak rate
    [cir] At least every 30 days, perform inventory control, conducted 
according to Department of Defense (DoD) Directive 4140.25; Air 
Transport Association (ATA) Airport Fuel Facility Operations and 
Maintenance Guidance Manual; or equivalent procedures that can detect a 
leak equal to or less than 0.5 percent of flow through and either
    [ssquf] At least every two years, perform a tank tightness test 
that can detect a 0.5 gallon per hour leak rate or
    [ssquf] At least every 30 days, perform vapor monitoring or 
groundwater monitoring (conducted according to Sec.  280.43(e) or (f), 
respectively, for the stored regulated substance)


[[Page 41586]]


    The implementing agency may approve another method of release 
detection if the owner or operator can demonstrate the method can 
detect a release as effectively as any of methods listed above. In 
comparing methods, the implementing agency shall consider the size of 
release the method can detect and frequency and reliability of 
detection.
Release Detection--Piping
    Underground piping associated with field-constructed tanks less

Release Prevention
    This final UST regulation requires airport hydrant systems and 
field-constructed tanks meet corrosion protection, spill, overfill, and 
walkthrough inspection requirements. Corrosion protection installed on 
airport hydrant systems and field-constructed tanks must meet either:

 New tank and piping standards described in Sec.  280.20, 
except that new and replaced hydrant piping and piping associated with 
field-constructed tanks greater than 50,000 gallons need not be 
secondarily contained or
 Airport hydrant systems and field-constructed tanks installed 
on or before the effective date of the final UST regulation must either 
meet the corrosion protection upgrade requirements in Sec.  
280.252(b)(1) or the new tank and piping standards described above

    Airport hydrant systems and field-constructed tanks installed on or 
before the effective date of the final UST regulation that are not 
upgraded according to Sec.  280.252(b) within three years of the 
effective date of the final UST regulation must be permanently closed 
according to subpart G. The presence of an internal lining does not 
meet the corrosion protection upgrade requirement.
    Owners and operators of airport hydrant systems and field-
constructed tanks must install spill and overfill prevention equipment 
and meet the

[[Page 41587]]

periodic spill testing and overfill inspection requirements of Sec.  
280.35. Owners and operators must install the equipment and conduct the 
first spill test and overfill inspection no later than three years 
after the effective date of this final UST regulation and every three 
years thereafter. For airport hydrant systems brought into use after 
the effective date of this final UST regulation, spill and overfill 
prevention equipment requirements must be met at installation.
    Owners and operators must conduct walkthrough inspections that meet 
the requirements of Sec.  280.252(c). Owners and operators must conduct 
the first inspection within three years after the effective date of the 
final UST regulation. In addition to the items inspected as part of the 
walkthrough inspection for other regulated UST systems, owners and 
operators of airport hydrant systems must inspect hydrant pits and 
hydrant piping vaults every 30 days for areas that do not require 
confined space entry according to the Occupational Safety and Health 
Administration (OSHA) and annually for areas that do require confined 
space entry. Owners and operators must keep documentation of the 
inspection according to Sec.  280.36(b).
Notification
    This final UST regulation requires owners and operators of 
regulated airport hydrant systems and field-constructed tanks meet 
these notification requirements:

 For airport hydrant systems and field-constructed tanks 
currently installed, owners and operators must submit no later than 3 
years after the effective date of this final UST regulation a one-time 
notification to their implementing agency that their systems exist
 For airport hydrant systems and field-constructed tanks 
installed after the effective date of the final UST regulation, owners 
and operators must provide their implementing agency a notification of 
each newly installed system within 30 days of bringing each system into 
use
 Owners must provide their implementing agency a notification 
of ownership change for each newly acquired airport hydrant system or 
field-constructed tank within 30 days of the date on which the new 
owner assumes ownership
Financial Responsibility
    This final UST regulation requires owners and operators of airport 
hydrant systems and field-constructed tanks that have not been 
permanently closed meet the financial responsibility requirements in 
subpart H at the time the one-time notification of existence is 
submitted to the implementing agency. Owners and operators who install 
these systems after the effective date of this final UST regulation 
must meet the financial responsibility requirements at installation. 
This requirement does not apply to state or federal owners of airport 
hydrant systems and field-constructed tanks.
Partially Excluded Components
    This final UST regulation excludes aboveground storage tanks 
associated with airport hydrant systems and field-constructed tanks 
from the requirements of subparts B, C, D, E, G, J, and K. Owners and 
operators are still required to comply with subparts A (Program Scope 
and Installation Requirements for Partially Excluded UST Systems); and 
F (Release Response and Corrective Action for UST Systems Containing 
Petroleum or Hazardous Substances) for these tanks.
Operator Training
    This final UST regulation requires owners and operators of airport 
hydrant systems and field-constructed tanks meet the operator training 
requirements in subpart J.
Closure Requirements for Previously Closed Tanks
    When directed by the implementing agency, owners and operators of 
airport hydrant systems and field-constructed tanks permanently closed 
before the effective date of this final UST regulation must assess the 
excavation zone and close the UST system according to subpart G if 
releases from the UST may, in the judgment of the implementing agency, 
pose a current or potential threat to human health and the environment.
Background
    Tanks and piping associated with airport hydrant systems and field-
constructed tanks can store millions of gallons of fuel and handle 
large volumes of regulated substances on a daily basis. Leaks from 
these systems can contaminate subsurface soil beneath the airport apron 
and runways, groundwater, and nearby surface water systems, posing a 
significant risk to human health and the environment. As a result, EPA 
is removing the deferral.
    Some commenters indicated EPA needed to justify that airport 
hydrant systems and field-constructed tanks are leaking in order to 
regulate them. The 1988 UST regulation required owners and operators 
report only confirmed releases from these tanks to implementing 
agencies. Owners and operators were not required to report suspected 
releases to implementing agencies, which sometimes resulted in gaps for 
ensuring proper site investigations or transmission of sufficient 
release information. As a result, implementing agencies have little to 
no available historical records regarding releases of regulated 
substances from airport hydrant systems and field-constructed tanks.
    In the 2011 proposed UST regulation, EPA provided details on 
several releases that previously occurred at airport hydrant systems. 
Since that time, EPA identified additional information on releases from 
both DoD and commercial airport hydrant systems. For example, at 
Hartsfield Jackson International Airport in Georgia, active remediation 
and free product recovery is ongoing (as of 2014) due to a 1988 release 
of an estimated 14,000 gallons of jet fuel.\44\ In 2003, an estimated 
100,000 gallons of jet fuel leaked from the valves and flanges of an 
airport hydrant system at Minneapolis-St. Paul International Airport in 
Minnesota. Some of the jet fuel was released into the sanitary sewer 
and nearby waterway. During the investigation of the jet fuel release, 
personnel discovered a second jet fuel leak at a different concourse; 
this leak impacted the stormwater system and produced oily sheens in 
the Minnesota River. Responsible parties agreed to pay civil penalties 
and complete environmental projects, including continued site 
remediation and fuel recovery.\45\ In 1983 at Camp Lejeune, North 
Carolina, investigators discovered multiple feet of free product while 
using a hand auger to investigate the cause of a fuel inventory 
discrepancy.\46\ In addition, from the 1960s to the 1980s, thousands of 
gallons of jet fuel leaked from a former airport hydrant system at Pope 
Air Force Base, North Carolina. At one time, it was noted that as much 
as 75,000 gallons of free product was floating on top of the 
groundwater because of these releases. As of 2014, the site is 
undergoing remediation.\47\ In addition, at Marine Corps Air Station 
Cherry Point, North Carolina there have been multiple releases from the 
airport

[[Page 41588]]

hydrant system underground piping. The station was cited twice in the 
1990s for contaminating soil and groundwater under this fuel facility 
due to leaking tanks or fuel spills. An extensive environmental 
remediation effort is underway in 2014 to clean this site. 
Contamination from many of the releases combined and migrated to form a 
single plume.

    In the 2011 proposed UST regulation, EPA also provided details on 
several previous releases that occurred from field-constructed tanks. 
Since that time, EPA identified additional anecdotal information on 
releases from field-constructed tanks. At Adak Island, Alaska's Tank 
Farm A, records show fuel was released at various times from 21,000 to 
420,000 gallon field-constructed tanks and piping. As of 2014, all 
tanks have been removed, but the former fuel farm is still undergoing 
remediation through long term monitoring and monitored natural 
attenuation.\48\ Also at Adak Island, an overfill during a fuel 
transfer caused 142,800 gallons of diesel fuel to leak from a 4.8 
million gallon underground field-constructed tank into the immediate 
and surrounding environment, causing harm to native wildlife.\49\

    Releases can have a major impact on human health and the 
environment. Release prevention equipment, regular release detection 
tests, operator training, periodic walkthrough inspections, and proper 
operation and maintenance are keys to preventing and quickly 
identifying releases before they contaminate the surrounding 
environment. This final UST regulation adds these requirements for 
airport hydrant systems and field-constructed tanks in order to help 
prevent and quickly detect leaks from these systems into the 
environment.
Definition of an Airport Hydrant System
    The 1988 UST regulation did not provide a definition for airport 
hydrant system. In the 2011 proposed UST regulation, EPA provided a 
definition of an airport hydrant system to clarify what components 
would be regulated. However, that definition was based on an airport 
hydrant system that received fuel at a single delivery point, designed 
with all components operating in tandem, and included only the 
immediate piping and tank directly feeding the airport hydrant piping. 
To clarify for owners and operators, EPA presented scenarios of typical 
airport hydrant systems in a guidance document provided during the 
public comment period.
    After publishing the 2011 proposed UST regulation, EPA met with 
stakeholders to gather more information on airport hydrant system 
design and operation.50 51 EPA also provided another 
iteration of the schematics that contained better defined airport 
hydrant system scenarios. However, some commenters still were confused 
about which specific components of an airport hydrant system would be 
regulated.\52\

---------------------------------------------------------------------------

    Many commenters requested that EPA provide guidance on how to 
perform the calculations to determine whether the airport hydrant 
system meets the definition of an underground storage tank and 
requested clarification of system components. In response to these 
comments, EPA is providing guidance below.
    In order for an airport hydrant system to be subject to the final 
UST regulation, it must first meet the definition of an underground 
storage tank. Airport hydrant systems are not regulated UST systems 
under 40 CFR part 280, unless 10 percent or more of the total capacity 
of the system is beneath the surface of the ground. When performing the 
calculation, include all tanks and underground piping that are part of 
the airport hydrant system. An airport hydrant system may have one or 
more of the following connected together: Aboveground tanks, 
underground tanks, field-constructed tanks, or factory constructed 
tanks. Below are two examples. Note that aboveground piping is not 
included when calculating the total volume.
    Example 1: A 1 million gallon aboveground storage tank (AST) 
connected to underground piping with a capacity of 100,000 gallons does 
not meet the definition of an UST, as explained below:

1 million gallons (AST) + 100,000 gallons (underground pipe) = 1.1 
million gallons total volume
1.1 million gallons x 10% = 110,000 gallons

    The volume of the underground piping (100,000 gallons) is less than 
10 percent of the total volume of the tanks and underground piping 
(110,000 gallons).
    Example 2: A 2 million gallon AST feeds two 100,000 gallon field-
constructed underground storage tanks and two 50,000 gallon underground 
tanks constructed in the factory which feed 100,000 gallons of 
underground hydrant piping. Calculating these values yields a total 
system capacity of 2,400,000 gallons with 400,000 gallons underground. 
More than 16% of this airport hydrant system is underground making it 
an UST.
    In response to comments on the proposed definition, EPA is 
clarifying the definition of an airport hydrant system in this final 
UST regulation. EPA determined that multiple tanks grouped or 
interconnected together can function as one system to fuel an airport 
hydrant system. EPA agrees with commenters that it would not be 
feasible to separate these tanks to define an airport hydrant system. 
EPA also found that other tanks not directly connected to the 
underground airport hydrant piping also could feed the airport hydrant 
system. The Agency is concluding that an airport hydrant system may 
consist of interconnected aboveground and underground storage tanks 
(that could be constructed in the factory or field-constructed) and 
piping that function as integral and interchangeable components of the 
fueling system. Field-constructed tanks that are part of the airport 
hydrant system are treated as part of the airport hydrant system and 
not independent UST systems that are field-constructed. The airport 
hydrant system begins when regulated substance enters from an external 
source such as a pipeline, barge, rail car, or other motor vehicle 
carrier, but does not include the external source. Airport hydrant 
systems use large diameter piping and operate at pressures higher than 
those of a conventional UST. This final definition alleviates 
stakeholder uncertainty on which components of an airport hydrant 
system must meet the UST regulation by including all integral 
components that form an airport hydrant system and deliver fuel to the 
aircraft. These systems include underground piping and ASTs or USTs 
that hold aircraft fuel (for example, settling tanks or product 
recovery tanks). They do not include tanks or underground piping not 
storing aircraft fuel (for example, additive tanks) or tanks and 
underground piping not connected to the airport hydrant system (for 
example, a system that fuels an emergency power generator for a pump 
house). In addition, EPA is aware there may be instances where an 
airport hydrant system might include permanently installed dispensing

[[Page 41589]]

equipment at the end of the hydrant piping instead of a fill stand. 
However, since these systems still operate under high pressure and 
contain large diameter piping, we consider them to be airport hydrant 
systems.
Definition of a Field-Constructed Tank
    The preamble to the 1988 UST regulation described a field-
constructed tank as a tank usually constructed of steel or concrete and 
shaped like flat vertical cylinders, with a capacity of greater than 
50,000 gallons. Tanks that are primarily factory built, but assembled 
in the field, are considered factory built tanks. For example, welding 
two halves of a factory constructed tank together in the field does not 
qualify the tank as a field-constructed tank. Several commenters 
requested EPA define field-constructed tank in the final UST regulation 
in order for implementing agencies and owners and operators to know 
which tanks are applicable. While EPA thinks this term is self-evident, 
this final UST regulation defines field-constructed tank as a tank 
constructed in the field. For example, a tank constructed of concrete 
that is poured in the field, or a steel or fiberglass tank primarily 
fabricated in the field is considered field-constructed. Please note 
this definition excludes those tanks with components primarily 
manufactured in a factory with minimal assembly in the field. EPA 
considers those tanks are factory built tanks. Field-constructed tanks 
vary from sizes smaller than 50,000 gallons to sizes very large in 
capacity. Large capacity tanks may exceed size or shape limitations 
that prohibit transportation of the tank in whole to the UST site. 
Field-constructed tanks present an engineering, design, or 
transportation concern that cannot be addressed by fabrication in a 
factory or are more ideally addressed through in-field construction. 
This definition includes tanks that are mounded or partially buried, 
such as those defined in 40 CFR part 112, if 10 percent or more of the 
volume of the system is beneath the ground's surface or otherwise 
covered with earthen material. EPA considers a field-constructed tank 
that is part of a wastewater treatment system to be partially excluded 
from the final UST regulation according to Sec.  280.10(c). See section 
C-3 for additional information on the partial exclusion for wastewater 
treatment tank systems.
Universe of Field-Constructed Tanks and Airport Hydrant Systems 
Affected
    UST systems with field-constructed tanks are generally very large 
and, in the event of a release, pose a substantial threat to human 
health and the environment. Typical tank sizes range from 20,000 
gallons to greater than 2 million gallons. EPA is aware of 
approximately 330 UST systems with field-constructed tanks owned by the 
Department of Defense and 12 field-constructed tanks owned by the 
Department of Energy (DOE).
    One commenter objected to EPA regulating airport hydrant systems 
because the 2011 proposed UST regulation addressed airport hydrant 
systems at military facilities and did not include systems at 
commercial airports. When issuing the 2011 proposed UST regulation, EPA 
thought the universe of these systems was mainly owned by DoD, based on 
information from DoD and commercial airport representatives. The 2011 
proposed UST regulation also assumed the universe included two 
commercial airports with airport hydrant systems. Airlines for America 
(A4A, formerly known as Air Transport Association of America, Inc.) 
provided additional information during the public comment period that 
suggested nine commercial airports would be affected by the final UST 
regulation. As a result of the comments received, EPA did extensive 
research to confirm which commercial airports might be affected by the 
final UST regulation. EPA met with personnel from DoD and from eight of 
the nine suggested commercial airport facilities to gather additional 
information and determine the universe of airport hydrant systems that 
would have to comply with the final UST 
regulation.53 54 55 56 Additionally, EPA listened to 
concerns and answered questions about the 2011 proposed UST regulation. 
EPA also met with release detection vendors to determine whether 
commercial airports and DoD facilities could achieve release detection 
compliance within the specified time frames.57 58 59 EPA 
concluded that of the nine airports A4A named, eight would possibly be 
affected by the final UST regulation. Based on these meetings, EPA 
found that most of the commercial airport hydrant systems have release 
prevention and detection equipment currently installed on them and 
airport personnel are already performing various activities that can be 
modified to meet the final UST regulation.

Process for Obtaining Public Comment
    One commenter suggested that EPA:

 Did not follow all requirements to allow stakeholder input 
prior to issuing the 2011 proposed UST regulation
 Did not allow stakeholders adequate time to provide comments
 Failed to follow the correct public notice procedures
 Failed to inform stakeholders of two commercial airports that 
might be affected by the final UST regulation
 May have led commercial airport stakeholders to doubt that any 
commercial airport hydrant systems would be affected by the final UST 
regulation
    The commenter also suggested EPA should withdraw the 2011 proposed 
UST regulation because the administrative record and resulting proposal 
conflicted with Executive Order 13563 (Improving Regulation and 
Regulatory Review).\60\

    \60\ On January 18, 2011, President Obama issued Executive Order 
13563, which directed federal agencies to develop a preliminary plan 
which outlined the agency's approach for periodically reviewing 
regulations to determine whether any rules ``should be modified, 
streamlined, expanded, or repealed so as to make the agency's 
regulatory program more effective or less burdensome in achieving 
the regulatory objectives.''
---------------------------------------------------------------------------

    EPA disagrees with these comments. We performed extensive 
stakeholder outreach both prior to developing the 2011 proposed UST 
regulation and during the public comment period. In addition, EPA 
followed procedures required by the Administrative Procedure Act for 
providing public notice and requesting public comment through the 
Federal Register. In order to allow additional time for airport 
authorities to perform a preliminary assessment and respond to the 2011 
proposed UST regulation, EPA extended the public comment period by two 
months as requested by commenters.\61\ EPA met with all interested 
stakeholders who requested meetings, including representatives of 
commercial airports. EPA carefully researched information provided 
during the public comment period; this included verifying methods of 
release detection currently

[[Page 41590]]

in use at commercial airports and DoD facilities, as well as what 
methods would be technically feasible at those facilities. When issuing 
the 2011 proposed UST regulation, EPA thought Lambert-St. Louis 
International Airport and Denver International Airport were the only 
commercial airports that would be affected by the final UST regulation. 
EPA identified these airports in a meeting with Airlines for America. 
During that meeting, the Agency also received additional information on 
other airports possibly affected by the proposal.\62\ While EPA did not 
specifically identify the two commercial airports that would 
potentially be affected by the final UST regulation, the 1988 UST 
regulation has been in effect for over two decades and portions of it 
have applied to airport hydrant systems since that time. Owners and 
operators of these systems have been required to comply with those 
applicable portions of the UST regulation since 1988, and it has been 
the responsibility of owners and operators to determine whether their 
airport hydrant systems are regulated since the effective date of the 
1988 UST regulation. Nonetheless, EPA stated in the 2011 proposed UST 
regulation that airport hydrant systems are ``. . . mainly owned by the 
Department of Defense (DoD) . . .,'' not that DoD is the sole owner of 
all airport hydrant systems. This statement indicates there are non-DoD 
owned airport hydrant systems that could be affected by this final UST 
regulation.

Impacts of Regulating Airport Hydrant Systems and Field-Constructed 
Tanks
    Commenters generally supported removing the deferral for these 
systems. However, there were some commenters who opposed regulating 
these systems. A few commenters were concerned about the costs for 
owners and operators to comply with the release detection requirements 
of the final UST regulation. EPA acknowledges that some release 
detection methods may result in additional costs to owners and 
operators. However, EPA carefully researched current release detection 
efforts at commercial airports and DoD facilities and used that 
information to estimate costs. See the RIA, which is available in the 
docket for this action, for additional information about how we 
estimated costs.
Other Regulations That Affect Airport Hydrant Systems and Field-
Constructed Tanks
    To avoid overlapping regulations, several commenters suggested EPA 
evaluate other requirements that owners and operators of airport 
hydrant systems and field-constructed tanks perform as part of fuel 
management programs. One commenter also asserted that this evaluation 
was necessary to comply with Executive Order No. 13563.\63\ After 
issuing the 2011 proposed UST regulation, EPA performed this evaluation 
by gathering information on fuel management programs (such as release 
prevention, repairs, operation and maintenance, inspections, and 
operator training) owners and operators at these facilities must 
perform in order to meet other federal, state, and industry 
regulations.\64\ For example, EPA found that requirements administered 
by the Federal Aviation Authority (FAA), such as 14 CFR part 139 
(Certification of Airports), and directives, such as ATA 103 and United 
Facilities Criteria (UFC) 3-460-03, require owners and operators of 
airport hydrant systems inspect airport hydrant systems and connected 
components. EPA also found that 14 CFR part 139 (Certification of 
Airports) emphasizes overall airport safety practices.
---------------------------------------------------------------------------

    \63\ Executive Order 13563 requires federal agencies to avoid 
implementing unnecessary redundant requirements and promulgate 
regulations that are less burdensome to the regulated community.
    \64\ EPA performed an assessment of the following additional 
requirements that owners and operators follow: 40 CFR part 112 
(SPCC); 14 CFR part 139 (FAA); A4A 123; ATA 103; ATA O&M Guidance; 
UFC 3-460-1 [Proposed UST Requirements Compared To Existing Facility 
Requirements And Recommended Practices].
---------------------------------------------------------------------------

    One commenter asked whether EPA evaluated the SPCC requirements for 
regulating underground portions of airport hydrant systems. Another 
commenter suggested that EPA evaluate the effectiveness of existing 
state requirements for field-constructed tanks.\65\ EPA is aware that 
commercial airports and DoD facilities comply with SPCC requirements 
for their airport hydrant systems and field-constructed tanks. However, 
UST and SPCC regulations are complementary. The SPCC regulation focuses 
on oil discharges that could impact navigable waters, while the UST 
regulation focuses mainly on day-to-day maintenance and operation to 
prevent releases to soil and groundwater. For example, the SPCC 
regulation requires a tank inspection, such as an American Petroleum 
Institute (API) Standard 653 inspection, which ensures aboveground 
storage tanks and piping are structurally sound. In addition, 
regulatory overlap is mitigated by the SPCC regulation, which allows 
UST release detection as a method to meet its tank inspection 
requirement. The SPCC regulation requires owners and operators conduct 
integrity and leak testing of buried piping at the time of 
installation, modification, construction, relocation, or replacement, 
but does not specify a method, frequency, or leak rate. The UST 
regulation is more specific and requires periodic release detection 
testing of underground piping.
---------------------------------------------------------------------------

    \65\ New York allows owners and operators to perform a modified 
American Petroleum Institute Standard 653 inspection combined with 
monitoring well release detection for large field-constructed tanks.
---------------------------------------------------------------------------

    EPA thinks that other regulatory programs (such as SPCC and FAA) 
lack the necessary specificity or do not meet equivalency criteria we 
deem are necessary for these UST systems. Additionally, even though 
some A4A documents provide many recommended practices that owners and 
operators of airport hydrant systems and field-constructed tanks may 
follow for their fuel management programs, these practices are not 
regulatory requirements, and airports have the option of following 
them. Moreover, EPA developed a final UST regulation that is cost 
effective to the extent practical and is the least burdensome to owners 
and operators, yet still protects human health and the environment. 
This final UST regulation does not impose redundant requirements. 
Rather, it contains complementary requirements that will protect human 
health and the environment.
Effect on Airport Operations
    One commenter suggested the requirements in the 2011 proposed UST 
regulation were not legally or technically viable for commercial 
airports. That commenter said EPA should develop a separate regulation 
specific to commercial airport hydrant systems. In addition, a few 
commenters were concerned that removing the deferral for airport 
hydrant systems would cause service disruptions due to installing 
release prevention and detection equipment. Those commenters also said 
performing release prevention and detection would cause massive service 
delays, affect military missions, and threaten national security and 
the National Airspace System.
    Based on discussions with DoD prior to issuing the 2011 proposed 
UST regulation and talking to DoD and potentially affected airports 
after issuing it, EPA concluded that most facilities already have the 
necessary equipment to meet many of the requirements in the final UST 
regulation. EPA also concluded from those conversations that release 
detection is normally performed during service downtimes or when

[[Page 41591]]

operations are minimal. Some airport hydrant systems have the 
capability of transferring product flow to other sections of the 
airport hydrant system to avoid system downtime. DoD stated that leak 
testing is performed according to prescribed requirements in Florida 
and California and at least biennially in other states when funding 
allows. Where feasible, piping is normally tested in segments to meet 
testing leak rates; piping segments can be isolated to find leaks more 
efficiently. EPA learned that some airport hydrant systems are capable 
of bypassing areas when airport hydrant piping is being tested; this 
avoids total system shutdown and allows continued airport operation. In 
addition, many airport personnel perform daily operations and 
maintenance activities, such as hydrant pit inspections and leak 
monitoring, on airport hydrant system components to avoid product loss, 
ensure fuel quality, and ensure personnel safety.
    This final UST regulation incorporates many of those tasks that 
operators normally perform regularly to prevent and detect leaks from 
these systems. However, to meet the final UST regulation, owners and 
operators may need to make minor modifications to their current 
activities. Since many airports have mechanisms in place and are 
already performing release monitoring, meeting requirements in the 
final UST regulation will not severely affect airport operations or 
cause service delays severe enough to significantly affect the military 
mission or disrupt the National Airspace System. EPA concluded that the 
information we gathered since issuing the 2011 proposed UST regulation 
supports regulating these systems as required in the final UST 
regulation. In addition, this final UST regulation includes changes to 
ensure compliance requirements are less disruptive and further mitigate 
concerns regarding service disruptions, such as adding options owners 
and operators may use to meet the release detection requirement.
Implementation Time Frame
    EPA is aware that this final UST regulation adds new requirements 
for owners and operators, as well as implementing agencies which have 
not fully regulated airport hydrant systems and field-constructed tanks 
in the past. A few commenters voiced concerns that the proposed 
implementation time frames would not give owners and operators, or 
implementing agencies, adequate time to assess these systems and 
determine the proper course of action. EPA thinks providing a single 
effective date is important because it reduces the burden on 
implementing agencies, owners, and operators to track various 
compliance deadlines. EPA is also allowing owners and operators who use 
periodic tightness testing for certain piping to phase in release 
detection requirements up to seven years. Additionally, EPA thinks 
three years gives owners and operators sufficient time for planning and 
installing necessary equipment to meet the requirements in this final 
UST regulation.
Other Comments
    Commenters generally supported changing the applicability date for 
previously closed systems of airport hydrant systems and field-
constructed tanks, giving implementing agencies the flexibility to 
require a site assessment and proper closure of systems closed between 
the effective date of the 1988 UST regulation and this final UST 
regulation. EPA agrees with commenters. As a result, this final UST 
regulation requires owners and operators of field-constructed tanks and 
airport hydrant systems, which were permanently closed before the 
effective date of this final UST regulation, to conduct a site 
assessment and close the UST system according to the closure 
requirements if directed to do so by the implementing agency.
    In the 2011 proposed UST regulation, EPA asked commenters if we 
should consider alternative options for closing very large UST systems 
in place. Most commenters recommended that large field-constructed 
tanks either be removed or filled with an inert solid material to 
prevent releases of residual contamination to the environment. Others 
suggested EPA allow some flexibility when closing these UST systems in 
place. EPA agrees with commenters that implementing agencies may need 
to have more flexibility in addressing these systems at closure. EPA is 
modifying the closure requirement in Sec.  280.71(b) of the final UST 
regulation to allow closure in place in a manner approved by the 
implementing agency. This addition provides implementing agencies the 
option to determine that owners and operators may close the UST system 
in place without filling it with an inert solid material.
    One commenter recommended that EPA, in the final UST regulation, 
directly reference the military construction standard associated with 
field-constructed tank design and construction discussed in the 
preamble to the 2011 proposed UST regulation. EPA agrees with the 
commenter and is adding the military construction criteria UFC 3-460-
01--Petroleum Fuel Facilities to this final UST regulation.\66\ 
Although design standards are now available for aboveground field-
constructed tanks, EPA is not aware of standards written according to a 
national code of practice developed by a nationally recognized or 
independent testing laboratory for non-military field-constructed tanks 
and airport hydrant systems. If demand arises and a commercial standard 
is not developed to address the need, owners and operators may use the 
UFC, where applicable.
---------------------------------------------------------------------------

    \66\ UFC 3-460-01--Petroleum Fuel Facilities is a military 
construction criteria that includes basic requirements for the 
design of fueling systems; the design of receiving, dispensing, and 
storage facilities; ballast treatment and sludge removal; corrosion 
and fire protection; and environmental requirements.
---------------------------------------------------------------------------

Release Detection
Background
    In the preamble to the 1988 UST regulation, EPA discussed the large 
volumes of product throughput, large capacities, and long lengths of 
large diameter piping for airport hydrant systems. At the time, EPA 
believed release detection was not feasible for airport hydrant 
systems. These systems were monitored for releases periodically, but no 
single leak test existed as an industry standard. Inventory control was 
often used, but its sensitivity was limited due to the large product 
volumes airport hydrant systems typically handle. To allow more time 
for gathering information, EPA in the 1988 UST regulation deferred 
regulating airport hydrant systems from release detection requirements 
in subpart D. EPA also deferred UST systems with field-constructed 
tanks from most requirements in the 1988 UST regulation, due to a lack 
of appropriate release detection methods. At that time, EPA believed 
the majority of release detection methods applied to factory built tank 
systems and did not adequately work for UST systems with field-
constructed tanks or airport hydrant systems.
Challenges of Conventional Release Detection Methods
    Standard release detection methods can successfully test and detect 
releases on pressurized piping at commercial service stations, but that 
is not the case for airport hydrant systems and large diameter piping 
associated with field-constructed tanks. For a variety of reasons, the 
piping of most airport hydrant systems and field-constructed tanks 
cannot meet release detection

[[Page 41592]]

requirements in the 1988 UST regulation. High product throughput makes 
it difficult and expensive to achieve the same leak rate thresholds 
established for traditional UST systems within a reasonable time frame. 
Product temperature fluctuations present challenges for release 
detection testing of conventional underground piping. However, release 
detection for piping of airport hydrant systems and large diameter 
piping associated with field-constructed tanks poses greater 
challenges. As temperatures fluctuate, product expands or contracts, 
increasing or decreasing product volume and pressure. The magnitude of 
piping associated with these systems creates an even greater 
temperature fluctuation; there are varying temperature gradients 
throughout the length of piping. Fluctuating line pressure during a 
release detection test can mask an existing release or falsely indicate 
one occurred. In addition, the out of service period needed to test 
airport hydrant piping could range from one to several days after the 
last product transfer.
    Removing airport hydrant systems from service for extended periods 
will greatly impede their purpose of rapid and timely delivery of fuel 
to aircraft. When using pressure based testing methods to produce 
accurate leak test results, airport hydrant system piping needs to be 
isolated in appropriately sized segments. Some airport hydrant systems 
have numerous isolation points with connections for release detection 
equipment. Others have longer underground piping segments with 
isolation valves for testing located up to 0.5 miles apart. The greater 
the volume of a segment, the more time it takes to obtain a valid 
result at a given leak rate. Although technology is available, it may 
be cost prohibitive and require significant facility down time for 
owners and operators to monitor airport hydrant systems for releases at 
the rates and frequencies required in the 1988 UST regulation.
    EPA also recognizes that most release detection methods for factory 
built tanks are capable of monitoring UST systems with field-
constructed tanks up to 50,000 gallons. After evaluating current 
methods, EPA realized existing release detection options for tanks in 
subpart D of the 1988 UST regulation are generally not applicable to 
UST systems greater than 50,000 gallons because most methods are 
limited by tank capacity. EPA acknowledges the complexities in 
performing release detection on tanks significantly larger than 50,000 
gallons. It is critical to allow sufficient time for a tank to reach a 
state of equilibrium prior to performing a test. As tank size 
increases, the time for a tank to reach an equilibrium increases 
significantly. Based on discussions with release detection vendors, 
many larger tanks require multiple inactive days to yield an accurate 
test result.
    DoD owns most UST systems with field-constructed tanks. Taking 
these tanks out of service for multiple days to meet the 1988 release 
detection requirement would, in some cases, impede DoD's mission, be 
impractical to sustain, and result in significant costs.
Release Detection Is Now Available
    While release detection used for conventional USTs may not work 
well for airport hydrant systems and field-constructed tanks greater 
than 50,000 gallons, release detection methods specifically designed 
for these UST systems are now available. Over the last 25 years, the 
petroleum services industry has developed release detection 
technologies for airport hydrant systems and field-constructed tanks. 
The NWGLDE lists Large Diameter Line Leak Detection Method (6 Inches 
Diameter Or Above) and Bulk Underground Storage Tank Leak Detection 
Method (50,000 Gallons Or Greater), both of which identify methods 
capable of detecting releases from airport hydrant systems and field-
constructed tanks.\67\ EPA contacted several vendors to determine the 
strengths and limitations of release detection methods for these UST 
systems. EPA also talked with DoD's Defense Logistics Agency (DLA) 
Energy \68\ about challenges in addressing release detection 
requirements in states, such as California, which do not defer airport 
hydrant systems from release detection. Because they perform release 
detection on airport hydrant systems in other states, DLA Energy has 
significant information about airport hydrant system release detection. 
As of this final UST regulation, some state UST programs require 
release detection for UST systems with field-constructed tanks and 
airport hydrant systems.\69\

Underground Storage Tanks gathered additional information from seven

state's release detection requirements and compare those 
requirements to the release detection requirements in EPA's proposed 
2011 UST regulation.
---------------------------------------------------------------------------

Feasibility of Proposed Release Detection Options for Piping
    In order to allow owners and operators flexibility to meet the 
release detection requirement, EPA proposed these four alternatives for 
underground piping associated with airport hydrant systems and field-
constructed tanks greater than 50,000 gallons:

 Pressure based line testing methods
 Continuous interstitial monitoring
 Automatic line leak detector combined with interstitial 
monitoring and
 Other methods approved by implementing agencies

    EPA requested comment or additional data on the proposed release 
detection requirements to determine their feasibility. Several 
commenters said the options in the 2011 proposed UST regulation were 
insufficient and requested EPA provide options that offered owners and 
operators more choices. A4A provided EPA with the names of nine 
commercial airports that could be affected by the final UST regulation 
and the feasibility of applying the release detection methods discussed 
in the 2011 proposed UST regulation to these airports. This information 
helped EPA further refine this final airport hydrant system 
requirements, including release detection.
    A4A stated that the only feasible choice EPA provided was pressure 
based methods and substantial retrofits would be required to meet the 
requirements at Chicago O'Hare International Airport (ORD), John F. 
Kennedy International Airport (JFK), and possibly other airports. 
However, EPA through our analysis and in depth discussions with those 
airports, thinks the airport hydrant system at JFK, as currently 
configured, may not meet the definition of an UST in this final UST 
regulation; this means the requirements would not apply. In addition, 
if planned capital upgrades are completed on one of ORD's airport 
hydrant systems, that system may not meet the definition of an UST and 
would not be subject to this final UST regulation. If configurations 
for either of these airport hydrant systems change in the future, the 
owner and operator must re-evaluate the system to determine if it meets 
the definition of UST in this final UST regulation. Owners and 
operators are responsible for determining whether their airport hydrant 
systems meet the definition of an UST and, if necessary, comply with 
this final UST regulation.
    As a result of comments and while developing the final UST 
regulation, EPA met with DoD, A4A, personnel

[[Page 41593]]

representing potentially impacted commercial airports, and release 
detection vendors to develop release detection methods for the final 
UST regulation and determine how or if commercial airports and DoD 
facilities could achieve compliance within the specified time 
frames.70 71 72 73 74 From those discussions, EPA found that 
most, if not all, of the potentially affected commercial airports have 
or will have mechanisms in place to achieve compliance with the release 
detection requirements in this final UST regulation. In addition, 
owners and operators already implement release detection according to 
technical requirements in states where airport hydrant systems are not 
deferred. EPA found that many of these airport hydrant systems perform 
a type of inventory management and hydrostatic testing of the piping 
system to detect pressure changes in the UST system. EPA determined 
that although the 1988 UST regulation did not require airport hydrant 
system owners and operators perform these tests, both DoD facilities 
and commercial airports have already been performing various fuel 
management methods to monitor and track fuel inventories.

Release Detection Options for Piping in the Final UST Regulation
    Based on comments, EPA is providing flexibility for owners and 
operators of piping associated with airport hydrant systems and field-
constructed tanks greater than 50,000 gallons to meet the release 
detection requirements. This final UST regulation modifies the piping 
release detection options in the 2011 proposed UST regulation and 
incorporates some of the methods currently used at commercial airports 
and DoD facilities. Owners and operators of these systems may use 
existing piping release detection options provided in subpart D (except 
for passive groundwater and vapor monitoring, which must be combined 
with inventory control as described below), or they may use alternative 
piping release detection methods in Sec.  280.252(d)(2). EPA thinks 
these options are reasonable and represent an appropriate balance of 
practicality and protectiveness. Piping associated with field-
constructed tanks 50,000 gallons or less in capacity must use the 
release detection options listed in subpart D.
Pressure Based Testing
    The final UST regulation allows owners and operators to perform 
pressure based testing methods according to performance criteria 
dependent on volume of the line segment tested. These criteria provide 
specific performance thresholds for both semiannual and annual testing. 
Owners and operators may perform semiannual or annual line testing at 
or above operating pressure with a probability of detection of 0.95 and 
a probability of false alarm of 0.05. This method allows owners and 
operators to meet a variable leak rate based on piping test section 
volume. The leak rate ranges from 1 to 3 gallons per hour, depending on 
piping volume for semiannual testing and from 0.5 to 1.5 gallons per 
hour for annual testing. The final UST regulation establishes 3 gallons 
per hour as the maximum threshold because the majority of available 
testing methods are capable of meeting this leak rate.
    For the first six years (or two test periods), piping segments that 
cannot meet a 3 gallons per hour threshold are allowed to meet a higher 
threshold of up to 6 gallons per hour. Available methods are capable of 
testing segments to a leak rate of 6 gallons per hour. The higher 
threshold provides for use of existing test methods during the first 
six year period. Six years will provide owners and operators time to 
upgrade their piping systems to meet the up to 3 gallons per hour 
threshold for semiannual testing. Between years six and seven, owners 
and operators must conduct one additional tightness test that, at a 
minimum, meets the semiannual testing threshold. In the seventh year, 
owners and operators must begin meeting the semiannual or annual line 
tightness testing requirements according to the requirements in Sec.  
280.252(d)(2)(i). EPA is providing a three year phase-in period for the 
remaining release detection options, because these methods will not 
require significant construction or upgrades for implementation.
    EPA asked commenters whether other release detection options should 
be considered for underground piping associated with airport hydrant 
systems and field-constructed tanks greater than 50,000 gallons. Based 
on comments, EPA is adding inventory control, groundwater and vapor 
monitoring, and other methods for piping as release detection options 
in this final UST regulation.
Inventory Control
    EPA reviewed performance standards for daily inventory control 
procedures used by DoD and the commercial airports identified by 
A4A.75 76 Based on performance standards for daily inventory 
control procedures performed by both DoD and A4A, EPA is allowing 
inventory control as part of a combination method of release detection. 
EPA chose 0.5 percent of flow through as the performance standard for 
inventory control because this value represents the maximum tolerance 
allowed under the performance standard for products typically stored or 
handled by airport hydrant systems. Owners and operators may conduct 
inventory control according to DoD Directive 4140.25, ATA's Airport 
Fuel Facility Operations and Maintenance Guidance Manual, or equivalent 
procedures. EPA is allowing this method in combination with either a 
pressure based line tightness test using the leak rates from the 
semiannual test in Sec.  280.252(d)(2)(i) at least once every two 
years, or passive groundwater or vapor monitoring once every 30 days as 
described below.
---------------------------------------------------------------------------

    \75\ DoD's Bulk Petroleum Management Policy--DoD 4140.25-M,

recognizes that petroleum products are subject to losses and gains. 
The tolerance factor that represents the amount of fuel which might 
be lost or gained under normal conditions varies by product and 
status of fuel (i.e., storage or in transit). These values in the 
policy represent standard tolerances (i.e., system flow-through) for 
various products in transit and storage: (1) Aviation and motor gas 
= 0.5 percent and 0.5 percent; (2) JP4 = 0.5 percent and 0.3 
percent; (3) Jet Fuel, Distillates, Residuals = 0.5 percent and 0.25 
percent; and (4) JP5, JP8, DF2, F76, etc. = varies by individual 
agreements with airports and 0.5 percent.

Inventory 2011.2. The two documents provide guidance for operators 
to investigate, report, or explain any variances exceeding 0.1 percent.
---------------------------------------------------------------------------

Groundwater and Vapor Monitoring
    EPA proposed to phase out groundwater and vapor monitoring as 
release detection methods in the 2011 proposed UST regulation. However, 
this final UST regulation retains these methods with modifications. See 
section D-6 for more information. These methods are also allowed with 
some modifications in subpart K. EPA divided vapor monitoring into two 
categories: Active monitoring for chemical markers or tracers and 
passive monitoring for stored product in the tank system. Owners and 
operators of these systems

[[Page 41594]]

may use active vapor monitoring methods characterized by testing or 
monitoring of chemical markers or a tracer compound placed in the tank 
system, according to Sec.  280.43(e) to detect a release of at least 
0.1 gallon per hour with probabilities of detection and false alarm of 
0.95 and 0.05, respectively. Owners and operators choosing this option 
must conduct this test at least once every two years. This method may 
be used as a stand-alone method of release detection.
    Owners and operators may also combine passive vapor or groundwater 
monitoring with inventory control, described above, that can detect a 
release of at least 0.5 percent of flow through at least every 30 days. 
Passive vapor monitoring or groundwater monitoring must be conducted at 
least every 30 days according to Sec.  280.43(e) or (f), respectively.
Other Methods for Piping
    The final UST regulation maintains the option for owners and 
operators to use alternative methods of release detection for piping 
approved by the implementing agency, as discussed in the 2011 proposed 
UST regulation. This provides flexibility for owners and operators to 
comply by using methods or a combination of methods equivalent to the 
requirements in Sec.  280.252(d)(2). EPA recognized that other methods 
not included in Sec.  280.252(d)(2) could be acceptable, as long as 
they are as effective and are approved by implementing agencies. The 
performance criteria for piping release detection methods in Sec.  
280.252(d)(2) provide owners and operators with information about how 
to demonstrate the effectiveness of release detection methods that must 
be approved by the implementing agency.
Proposed Release Detection Options for Piping Not Included in the Final 
UST Regulation
    Because piping segments associated with airport hydrant systems and 
field-constructed tanks can contain large volumes of regulated 
substances, EPA asked commenters if it was feasible to require ALLDs to 
detect a leak at 3 gallons per hour at 10 pounds per square inch line 
pressure within one hour or equivalent. EPA anticipated receiving 
information on the appropriate leak rate for ALLDs on this piping. EPA 
did not receive any indication that current performance standards of 
ALLDs could be modified for these systems. Although some portions of 
existing systems may be able to use this option, EPA agrees it is not 
feasible to use an ALLD with interstitial monitoring on piping 
associated with airport hydrant systems and field-constructed tanks.
    This final UST regulation modifies the 2011 proposed UST 
regulation; owners and operators of airport hydrant systems or piping 
associated with field-constructed tanks greater than 50,000 gallons are 
not provided specific requirements in this final UST regulation for 
using continuous interstitial monitoring and the combination of 
automatic line leak detectors with interstitial monitoring for piping. 
Many of these systems lack secondary containment and automatic line 
leak detectors cannot adapt to the operating pressures of these 
systems. In the 2011 proposed UST regulation, EPA asked if testing the 
piping for airport hydrant systems and field-constructed tanks at 
operating pressure was sufficient. The 1988 UST regulation requires 
owners and operators test conventional systems at one and a half times 
operating pressure. EPA is aware that airport hydrant system piping 
operates at high pressures and agrees with commenters who stated that 
testing above operating pressure might be infeasible. This final UST 
regulation requires owners and operators to test these systems at least 
at operating pressure, because these large piping systems operate at 
pressures much higher than conventional gasoline stations. However, EPA 
is allowing testing at or above operating pressure, but is not 
providing a set value. Professional testers can decide the appropriate 
pressure to test these systems, as long as the pressure is at least the 
operating pressure of the system.
Release Detection Requirements for Tanks Associated With Airport 
Hydrant Systems and Field-Constructed Tanks
    This final UST regulation establishes release detection 
requirements for tanks associated with airport hydrant systems and 
field-constructed tanks. Airport hydrant systems may consist of a 
series of large capacity shop fabricated tanks, although some airport 
hydrant systems use field-constructed tanks. Shop fabricated tanks and 
field-constructed tanks with a capacity less than or equal to 50,000 
gallons must meet the requirements in subpart D. Field-constructed 
tanks with capacity greater than 50,000 gallons must either be 
monitored using release detection methods in subpart D (except for 
passive groundwater and vapor monitoring which must be combined with 
inventory control as described below) or use one of the alternative 
methods for tanks listed at Sec.  280.252(d)(1).
Feasibility of Proposed Release Detection Options for Field-Constructed 
Tanks
    To allow owners and operators more flexibility in meeting the 
release detection requirement, EPA proposed these four alternatives for 
UST systems with field-constructed tanks greater than 50,000 gallons:
     Annual tank tightness test
     Automatic tank gauging system that can detect a 1 gph leak 
combined with a tank tightness test every three years
     Automatic tank gauging system that can detect a 2 gph leak 
combined with a tank tightness test every two years and
     Other methods approved by the implementing agency
    EPA requested comment or additional data on the proposed release 
detection options to determine their feasibility. Most commenters 
thought the release detection options were appropriate and sufficient. 
One commenter thought EPA should include chemical marker or tracer 
testing. Another commenter thought EPA should expand the types of 
release detection methods specified in the final UST regulation to 
include use of sensors, probes, monthly visual inspections, or other 
methods approved by the implementing agency.
    EPA met with and obtained information from DoD and release 
detection vendors throughout the regulatory process. EPA researched 
suggested release detection options and standard practices conducted by 
DoD following the public comment period for the 2011 proposed UST 
regulation. EPA found that these facilities perform inventory 
management on their UST systems. EPA determined that although not 
performed as specified in the 1988 UST regulation, some DoD facilities 
are performing fuel management methods to monitor and track fuel 
inventories for their field-constructed tanks.77 78

Release Detection Options for Field-Constructed Tanks in the Final UST 
Regulation
    Based on comments and additional information from DoD as well as 
commercial airports about their operations, EPA is including in this 
final UST regulation all release

[[Page 41595]]

detection options discussed in the 2011 proposed UST regulation. EPA is 
also adding three other options to this final UST regulation. Owners 
and operators of field-constructed tanks less than or equal to 50,000 
gallons must meet the release detection requirements in subpart D. 
Owners and operators of field-constructed tanks greater than 50,000 
gallons must use the alternative release detection methods described in 
subpart K or the release detection options in subpart D (except that 
groundwater and vapor monitoring must be used in combination with 
inventory control as described below). EPA thinks these options are 
reasonable and will quickly detect releases when they occur.
Tank Tightness Testing
    In the 2011 proposed UST regulation, EPA discussed the option of 
owners and operators performing annual tank tightness testing that can 
detect a 0.5 gallon per hour leak rate. EPA proposed this performance 
standard based on information about leaks from several field-
constructed tanks. The information indicated leak rates from the tanks 
ranged from 0.31 gph to 10 gph, with a median leak rate of 0.58 gph. 
EPA determined that most available methods were capable of meeting the 
proposed leak rate of 0.5 gph. EPA did not receive comments regarding 
the performance standard during the public comment period. The final 
UST regulation retains the option for owners and operators to perform 
annual underground tank tightness testing that can detect a 0.5 gallon 
per hour leak rate.
Automatic Tank Gauging Combinations with Tank Tightness Testing
    This final UST regulation allows owners and operators to combine an 
automatic tank gauging system with a tank tightness test that achieves 
different leak rates during different periods of performance. One 
combination uses an automatic tank gauging system performing release 
detection at least every 30 days that can detect a leak rate less than 
or equal to 1 gallon per hour with a tank tightness test that can 
detect a 0.2 gallon per hour leak rate performed at least every three 
years. Another combination couples an automatic tank gauging system 
performing release detection at least every 30 days that can detect a 
leak rate less than or equal to 2 gallons per hour with a tank 
tightness test that can detect a 0.2 gallon per hour leak rate 
performed at least every two years. This automatic tank gauging 
requirement is different from the release detection requirement in the 
1988 UST regulation for factory built tanks. These leak rates and time 
frames for release detection testing are appropriate because they will 
detect releases within a reasonable time frame, given the large tank 
sizes and time needed to perform testing on these tanks.
Inventory Control
    This final UST regulation allows inventory control combined with 
one of these methods: passive groundwater monitoring every 30 days, 
passive vapor monitoring every 30 days, or a 0.5 gallon per hour tank 
tightness test performed at least once every two years. The inventory 
control option must meet the same requirements as inventory control for 
piping associated with airport hydrant systems and field-constructed 
tanks described in the Release Detection Options for Piping in the 
Final UST Regulation section above.
Groundwater and Vapor Monitoring
    This final UST regulation allows active vapor monitoring for tanks 
using the same requirements as described in the Release Detection 
Options for Piping in the Final UST Regulation section above. In 
addition, owners and operators may also use a combination method 
incorporating inventory control and passive vapor monitoring or 
groundwater monitoring using the requirements described in the Release 
Detection Options for Piping in the Final UST Regulation section above.
Other Methods for Field-Constructed Tanks
    Implementing agencies may approve another method if the owner and 
operator demonstrate the method can detect a release as effectively as 
any of the other five methods described in the Release Detection 
Options for Field-Constructed Tanks section. In comparing methods, an 
implementing agency shall consider the size of release the method can 
detect and frequency and reliability of detection. Other methods are 
described in Other Methods for Piping.
Release Detection Recordkeeping
    This final UST regulation requires owners and operators maintain 
records of release detection for field-constructed tanks and airport 
hydrant systems in accordance with Sec.  280.45. The results of any 
sampling, testing, or monitoring must be maintained for at least one 
year except as follows: Tank tightness testing; line tightness testing; 
and vapor monitoring using a tracer compound placed in the tank system 
must retain records until the next test is conducted. EPA is requiring 
owners and operators maintain these records until the next test is 
conducted because owners and operators can choose different time frames 
to conduct release detection testing. This additional flexibility 
results in some testing occurring at frequencies ranging from less than 
one year to up to three years.
Release Prevention
    As with all other regulated UST systems, this final UST regulation 
requires airport hydrant systems and field-constructed tanks meet 
corrosion protection, spill, and overfill requirements, as well as 
walkthrough inspections.
Corrosion Protection
    This final UST regulation requires all airport hydrant systems and 
field-constructed tanks that routinely contain regulated substances and 
are in contact with the ground to meet corrosion protection 
requirements in Sec.  280.252(b)(1). Metal tanks and piping which are 
encased or surrounded by concrete have no metal in contact with the 
ground and are not subject to the corrosion protection requirements. 
Because interim prohibition for deferred UST systems in the 1988 UST 
regulation has been in effect since May 1985, many of these systems are 
already equipped with corrosion protection (that is, constructed of: 
Non-corrodible material, coated and cathodically protected steel, 
fiberglass reinforced plastic, or steel tank clad with fiberglass 
reinforced plastic). In this final UST regulation, EPA renames Sec.  
280.11 to Installation requirements for partially excluded UST systems. 
For corrosion protection, airport hydrant systems and field-constructed 
tanks must meet the requirements in Sec.  280.252(b)(1). Owners and 
operators must meet this requirement within three years of the 
effective date of this final UST regulation.
    This final UST regulation does not allow an internal lining as a 
method for meeting the corrosion protection upgrade requirement. EPA is 
not allowing an internal lining as corrosion protection because it does 
not protect steel in contact with the ground from corroding and causing 
a release to the environment. Field-constructed tanks and tanks 
associated with airport hydrant systems, which are not upgraded 
according to Sec.  280.252(b), and are installed on or before the 
effective date of this final UST regulation must be permanently closed 
according to Sec.  280.70.
Spill and Overfill Prevention
    EPA concludes that using properly functioning equipment, which is

[[Page 41596]]

operated according to manufacturer guidelines, is necessary to protect 
human health and the environment. After discussions with industry, DoD, 
and commercial airport personnel, EPA understands that existing airport 
hydrant systems are generally already equipped with spill and overfill 
prevention equipment to prevent spills and overfills. This final UST 
regulation requires owners and operators of airport hydrant systems and 
field-constructed tanks to have spill and overfill prevention equipment 
and conduct testing or inspections of the equipment. This will ensure 
the systems and tanks operate properly, contain releases, and decrease 
the likelihood of a leak into the environment. Owners and operators 
must install spill and overfill prevention equipment and conduct the 
first test or inspection within three years of the effective date of 
this final UST regulation, then at least once every three years 
thereafter. For more information on spill prevention equipment testing 
and overfill prevention equipment inspections, see sections B-2 and B-
3, respectively.
Walkthrough Inspections
    Owners and operators need to properly operate and maintain their 
UST system equipment in order to prevent and quickly detect releases. 
Therefore, this final UST regulation adds requirements for owners and 
operators of airport hydrant systems and field-constructed tanks to 
perform periodic walkthrough inspections to prevent and quickly detect 
releases.
    EPA found that owners and operators of airport hydrant systems are 
required to ensure safety and fuel quality, and frequently inspect 
these systems as part of other requirements and recommendations to 
ensure system components are operating properly. In addition, EPA 
understands that airport hydrant systems and some field-constructed 
tank facilities are already performing operation and maintenance 
inspections that ensure their systems and associated spill and overfill 
equipment are operating properly. Thus, EPA found these requirements 
will impose little, if any, additional burden at these facilities. This 
final UST regulation requires owners and operators of airport hydrant 
systems and field-constructed tanks conduct walkthrough inspections 
according to Sec.  280.36. In addition, EPA is requiring owners and 
operators inspect hydrant pits and hydrant piping vaults. These areas 
are unique to airport hydrant systems. It is important to look at 
hydrant pits and hydrant piping vaults as part of periodic walkthrough 
inspections to ensure these areas are: Free of liquid and debris, not 
damaged, and free of leaks. Owners and operators must inspect these 
areas at least once every 30 days if OSHA confined space entry is not 
required or at least annually if OSHA confined space entry is required. 
See 29 CFR part 1910 for information about OSHA confined space entry. 
Some owners and operators already periodically check these areas using 
the ATA guidance manual, Airport Fuel Facility Operations and 
Maintenance Guidance Manual. Owners and operators must conduct the 
first inspection within three years of the effective date of the final 
UST regulation. For more information on walkthrough inspections, see 
section B-1.
Secondary Containment
    This final UST regulation does not require secondary containment 
for new and replaced piping associated with field-constructed tanks 
greater than 50,000 gallons in capacity or piping associated with 
airport hydrant systems. EPA understands this piping typically is 
larger diameter and runs for long distances, making it difficult to 
slope the piping to an interstitial monitoring area. In addition, EPA 
understands it is difficult to keep water out of the interstitial area 
of long piping runs. Since nearly all this piping is steel, corrosion 
can occur in the interstitial area when an electrolyte, such as water, 
is in the interstitial area. This corrosion can significantly shorten 
the piping's operational life. Corrosion protection on the outside of 
the piping protects the part of the piping in contact with the ground 
from corrosion, but does not protect the inside part of piping from 
corrosion. To prevent corrosion caused by water in the interstitial 
area, owners and operators would need to add corrosion protection 
inside the interstitial area of piping, which EPA realizes would be 
difficult to do. Given these issues, EPA has determined that requiring 
secondary containment for these piping runs is not practical.
    However, EPA is requiring secondary containment for new and 
replaced piping associated with field-constructed tanks 50,000 gallons 
or less that do not feed airport hydrant system piping. EPA understands 
that new, smaller field-constructed tanks, such as those constructed 
within tanks following permanent closure of an existing UST, typically 
have piping similar to that installed at commercial gasoline stations. 
This piping can effectively meet the secondary containment requirements 
and better protect the environment. For more information, see section 
A-2, Secondary Containment.
Notification
    The 1988 UST regulation did not require owners of airport hydrant 
systems or field-constructed tanks to comply with the notification 
requirements of Sec.  280.22, which included certifying proper 
installation of airport hydrant systems. The 2011 proposed UST 
regulation required owners and operators of airport hydrant systems and 
field-constructed tanks installed prior to the effective date of the 
final UST regulation provide notification of existence to implementing 
agencies within 30 days of the effective date of this final UST 
regulation. This final UST regulation modifies the 2011 proposed UST 
regulation by requiring owners and operators provide a one-time 
notification of existence to implementing agencies no later than 3 
years after the effective date of this final UST regulation. EPA agrees 
with commenters that airport hydrant system owners and operators need 
more than 30 days to provide the one-time notification of existence. 
This change allows owners and operators, as well as implementing 
agencies, time to identify airport hydrant systems covered by the final 
UST regulation and gives implementing agencies time to include these 
systems in their inventories. The final UST regulation does not 
consider currently installed tanks, including airport hydrant systems, 
as new UST systems. Therefore, EPA is requiring owners and operators 
only certify proper installation for airport hydrant systems and field-
constructed tanks installed on or after the effective date of the final 
UST regulation according to Sec.  280.22. In addition, EPA is requiring 
owners notify within 30 days of ownership change. See section D-3 for 
more information on notification requirements.
Financial Responsibility
    Because EPA is eliminating the deferral for airport hydrant systems 
and field-constructed tanks, they are no longer be excluded from the 
financial responsibility requirements in subpart H. Owners and 
operators who install these UST systems after the effective date of 
this final UST regulation must comply with the financial responsibility 
requirements at installation. Owners and operators of airport hydrant 
systems and field-constructed tanks in use as of the effective date of 
this final UST regulation must have financial responsibility when they 
submit the one-time notification of existence for

[[Page 41597]]

these systems. However, subpart H exempts federal and state entities, 
which means that federal and state owners and operators of airport 
hydrant systems and field-constructed tanks do not have to meet the 
financial responsibility requirement.
Operator Training
    EPA is aware that commercial airports are required to follow fuel 
facility training requirements of 14 CFR part 139; however, those 
requirements do not cover specifics of the UST requirements. This final 
UST regulation requires owners and operators of airport hydrant systems 
and field-constructed tanks meet the operator training requirements of 
subpart J. Owners and operators of some airport hydrant systems that 
are considered underground storage tanks may have already complied with 
state operator training requirements. For example, personnel from 
General Mitchell Field in Wisconsin report that operators have received 
Wisconsin class A and B operator training certification. All owners and 
operators must begin meeting this requirement not later than three 
years after the effective date of this final UST regulation. For more 
information see section A-1, Operator Training.
Partially Excluded Components
    EPA regulates UST systems, including tanks and underground piping, 
in 40 CFR part 280 and aboveground tanks in 40 CFR part 112 (Oil 
Pollution Prevention). Facilities with greater than 1,320 gallons of 
aboveground oil storage capacity that could reasonably be expected to 
discharge oil into navigable waters or adjoining shorelines are subject 
to the SPCC regulation under the authority of the Clean Water Act.\79\ 
The SPCC regulation includes requirements for oil spill prevention, 
preparedness, and response to prevent oil discharges into navigable 
waters and adjoining shorelines. The SPCC regulation also requires 
regular inspections of aboveground valves, piping, and appurtenances 
along with integrity and leak testing of buried piping at the time of 
installation, modification, construction, relocation, or replacement. 
Facilities regulated by the SPCC regulation must also prepare and 
maintain a written SPCC plan that includes measures to prevent, prepare 
for, and respond to oil discharges that threaten navigable waters or 
adjoining shorelines.
---------------------------------------------------------------------------

    \79\ https://www.ecfr.gov/cgi-bin/text-idx?c=ecfr&SID=b843807afdc641b203ffec44aa671d36&rgn=div5&view=text&node=40:23.0.1.1.7&idno=40.
---------------------------------------------------------------------------

    Aboveground storage tanks associated with airport hydrant systems 
and field-constructed tanks covered in this final UST regulation do not 
have to meet many of the requirements in the UST regulation because 
they are neither beneath the surface of the ground, nor in contact with 
the ground. For these reasons, the SPCC regulation is the most 
effective means of addressing the aboveground storage tanks associated 
with UST systems. Airport hydrant systems that do not meet the 
definition of UST system because the underground portion is less than 
10 percent of the system capacity may be subject to the SPCC regulation 
for both the aboveground and underground portions of the system. 
Underground storage tank components such as hydrant pits and piping 
vaults are considered part of the UST system and subject to the 
requirements in 40 CFR part 280.
Complementary Regulation of Partially Buried Tanks
    Partially buried (also called partially covered) field-constructed 
tanks may be regulated by both this final UST regulation and the SPCC 
regulation. The SPCC regulation exempts only completely buried storage 
tanks subject to all of 40 CFR part 280.\80\ Additionally, the SPCC 
regulation covers tanks situated on top of the ground's surface or 
partially buried (for example, bunkered, also referred to as mounded 
tanks) and considers these to be aboveground storage tanks. If 10 
percent or more of the total capacity of the tank or tanks and 
underground piping is underground, the tank system meets the definition 
of an UST regulated by 40 CFR part 280 or state equivalent program 
approved under 40 CFR part 281. Therefore, these containers or systems 
are covered by both SPCC and UST regulations. These regulations are 
complementary because the SPCC regulation focuses on oil discharges 
that could impact navigable waters or shorelines, while the UST 
regulation focuses primarily on day-to-day maintenance and operation to 
prevent releases that impact soil and groundwater.
---------------------------------------------------------------------------

    \80\ 40 CFR 112.2 defines completely buried as any container 
completely below grade and covered with earth, sand, gravel, 
asphalt, or other material. Containers in vaults, bunkered tanks, or 
partially buried tanks are considered aboveground storage containers 
for purposes of the part.
---------------------------------------------------------------------------

Change from Deferred to Partially Excluded
    The 2011 proposed UST regulation used the term deferred for 
aboveground storage tanks associated with airport hydrant systems and 
field-constructed tanks considered to be UST systems. The proposal 
indicated that although these aboveground storage tanks would be 
subject to some parts of the final UST regulation, EPA intended to 
continue evaluating whether to fully regulate them in the future. EPA 
reconsidered these aboveground storage tanks and is making the final 
determination that the SPCC requirements are the most effective means 
for addressing oil discharges from aboveground storage tanks. This 
final UST regulation excludes from subparts B, C, D, E, G, J, and K 
aboveground storage tanks associated with airport hydrant systems and 
field-constructed tanks. Aboveground storage tanks that are part of an 
UST system must continue to meet the requirements of subparts A and F.
3. Wastewater Treatment Tank Systems that Are Not Part of a Wastewater 
Treatment Facility Regulated Under Sections 402 or 307(b) of the Clean 
Water Act
    In the 2011 proposed UST regulation, EPA removed the existing 
deferral in Sec.  280.10(c)(1) for wastewater treatment tank systems 
that are not part of a wastewater treatment facility regulated under 
sections 402 or 307(b) of the Clean Water Act. Since the 1988 UST 
regulation, owners and operators of these systems (hereafter referred 
to as wastewater treatment tanks) were deferred from complying with 40 
CFR part 280, subparts B (UST Systems: Design, Construction, 
Installation and Notification); C (General Operating Requirements); D 
(Release Detection); E (Release Reporting, Investigation, and 
Confirmation); G (Out-of-Service UST Systems and Closure); and H 
(Financial Responsibility). Owners and operators have been required to 
comply with requirements for interim prohibition and release response 
and corrective action (40 CFR part 280, subparts A and F) since the 
effective date of the 1988 UST regulation. However, removing the 
deferral, as discussed in the 2011 proposed UST regulation, would have 
required owners and operators comply with all subparts of 40 CFR part 
280.
Change from Deferred to Partially Excluded
    The 1988 UST regulation used the term deferred for wastewater 
treatment tanks. Although these tanks were subject to some parts of the 
UST regulation, EPA intended to continue evaluating whether or not to 
regulate these tanks at a future date. EPA reconsidered these tanks and 
is making a final determination. EPA is excluding

[[Page 41598]]

these tanks from most requirements in this final UST regulation; 
however, the regulatory requirements in subparts A and F for these 
systems remain the same.
    EPA deferred wastewater treatment tanks in the 1988 UST regulation 
due to uncertainty about the number of tanks that existed and the 
appropriateness of release detection for these systems. EPA's intent in 
removing the deferral for these tanks in the 2011 proposed UST 
regulation was to regulate them further, which would protect human 
health and the environment from discharges of regulated substances 
contained in these systems. EPA used the proposal to obtain additional 
information on these systems, and determine if there were appropriate 
release prevention and detection technologies available to fully 
regulate them according to the UST regulation. According to commenter 
responses, EPA determined that these tanks are often subject to other 
environmental regulations; it may not be technically feasible to 
install release prevention and detection equipment on these systems due 
to varying designs of these systems; and many of these systems contain 
mostly water and are not significant sources of contamination.
Installation Requirements for Partially Excluded Tanks
    In the 1988 UST regulation, deferred wastewater treatment tanks 
were required to meet the interim prohibition requirements at Sec.  
280.11 (that is, corrosion protected, made of non-corrodible materials, 
or otherwise designed and constructed to prevent releases during the 
operating life of the facility due to corrosion or structural failure). 
Therefore, these tanks are already equipped with corrosion protection 
if they were installed after the effective date of the 1988 UST 
regulation. EPA thinks it is appropriate to maintain this requirement, 
which ensures these tanks are provided with some degree of corrosion 
protection to prevent releases into the environment. Because EPA is 
partially excluding these systems, the term interim prohibition no 
longer applies. Therefore, EPA is rewording the title of Sec.  280.11 
to Installation requirements for partially excluded UST systems. In 
addition, EPA is changing Sec.  280.11(a) to reflect that these 
requirements are installation requirements rather than prohibitions on 
installation.
    Many commenters did not support removing the deferral to regulate 
these UST systems and were unsure of the universe of wastewater 
treatment tanks. To address this concern, EPA developed a February 2012 
document describing wastewater treatment tanks that would have been 
regulated under the final UST regulation.\81\ Several commenters also 
voiced concern that regulating these systems may result in unintended 
consequences (for example, impracticability of technical requirements 
and dual regulation) for owners and operators and implementing 
agencies. To help determine the feasibility of the 2011 proposed UST 
regulation, EPA asked several stakeholders about operating various 
types of wastewater treatment tanks.82 83 84 EPA also 
gathered information from commenters about implementing other 
regulations that apply to these systems.85 86 87 88 After 
considering commenters' feedback, EPA concluded that the historic level 
of regulation for these tanks is appropriate and provides adequate 
controls to ensure environmental protection.

    This final UST regulation excludes owners and operators of 
wastewater treatment tanks from 40 CFR part 280, subparts B (UST 
Systems: Design, Construction, Installation and Notification); C 
(General Operating Requirements); D (Release Detection); E (Release 
Reporting, Investigation, and Confirmation); G (Out-of-Service UST 
Systems and Closure); H (Financial Responsibility); J (Operator 
Training); and K (UST Systems with Field-Constructed Tanks and Airport 
Hydrant Fuel Distribution Systems). EPA is basing this decision on 
maintaining the installation requirement (Sec.  280.11), other 
regulatory controls in place, and the additional information gathered. 
Owners and operators of wastewater treatment tank systems are still 
required to comply with subparts A (Program Scope and Installation 
Requirements for Partially Excluded UST Systems); and F (Release 
Response and Corrective Action for UST Systems Containing Petroleum or 
Hazardous Substances).
4. USTs Containing Radioactive Material and Emergency Generator UST 
Systems at Nuclear Power Generation Facilities Regulated by the Nuclear 
Regulatory Commission
    In the 2011 proposed UST regulation, EPA maintained the existing 
deferral in Sec.  280.10(c)(2) and (3) for USTs containing radioactive 
material and for emergency generator UST systems at nuclear power 
generation facilities regulated by the United States Nuclear Regulatory 
Commission (NRC). Since the 1988 UST regulation, owners and operators 
of these tanks were deferred from complying with 40 CFR part 280, 
subparts B (UST Systems: Design, Construction, Installation and 
Notification); C (General Operating Requirements); D (Release 
Detection); E (Release Reporting, Investigation, and Confirmation); G 
(Out-of-Service UST Systems and Closure); and H (Financial 
Responsibility). Owners and operators have been required to comply with 
requirements for interim prohibition and release response and 
corrective action (40 CFR part 280, subparts A and F) since the 
effective date of the 1988 UST regulation.
    After review of DOE Orders and NRC regulations,\89\ EPA determined 
these requirements are comparable to EPA requirements for new and 
existing USTs regarding spill and overfill control (Sec.  280.30); 
operation and maintenance of corrosion protection (Sec.  280.31); and 
release detection (40 CFR part 280, subpart D). DOE established 
standards for facility operations that: protect the public and 
environment from exposure to radiation from radioactive

responsibilities for implementing DOE O 435.1, Radioactive Waste

responsibilities for new or modified existing systems: Secondary 
containment designed to detect and contain releases, and compatible 
with material stored (Chapter II P(2)(b)); spill/overfill control 
(Chapter II(P)(2)(i)); release detection for tanks (Chapter 
II(Q)(2)(a)(1)), and other storage components (Chapter II(Q)(2)(c)); 
release detection for failed containment and/or other abnormal 
conditions (Chapter II(P)(2)(j)); monitoring and/or leak detection 
for secondary containment (Chapter IIP(2)(j)); corrosion protection

    EPA concludes it is appropriate to continue requiring release 
response and corrective action for these tanks, if the need arises. Due 
to the sensitive nature of these facilities, implementing agencies have 
flexibility to establish appropriate response and remediation 
requirements for owners and operators at these facilities.
Move from Deferred to Partially Excluded
    The 1988 UST regulation used the term deferred for USTs containing 
radioactive material and for emergency generator UST systems at nuclear 
power generation facilities regulated by the NRC. This indicated that 
although these tanks were subject to some parts of the UST regulation, 
EPA intended to continue evaluating the applicability of full 
regulation of these tanks at a future date. EPA reconsidered these 
tanks and is making a final determination. EPA is excluding these tanks 
from most requirements in this final UST regulation; however, the 
regulatory requirements in subparts A and F for these systems remain 
the same.
Installation Requirements for Partially Excluded Tanks
    In the 1988 UST regulation, deferred USTs containing radioactive 
material and emergency generator UST systems at nuclear power 
generation facilities regulated by NRC were required to meet the 
interim prohibition requirements of Sec.  280.11 (that is, corrosion 
protected, made of non-corrodible materials, or otherwise designed and 
constructed to prevent releases during the operating life of the 
facility due to corrosion or structural failure). While NRC's 
regulation addresses design and installation standards, interim 
prohibition requirements have been in effect since the 1988 UST 
regulation. Accordingly, owners and operators have had to follow this 
requirement since the effective date of the 1988 UST regulation. EPA 
has no information suggesting that maintaining this requirement has 
been an issue for owners and operators. After considering commenters' 
feedback, EPA concluded that the historic level of regulation for these 
tanks is appropriate and provides adequate environmental controls to 
ensure environmental protection. Therefore, this final UST regulation 
continues to require that owners and operators of these tanks comply 
with the requirements of Sec.  280.11. Because EPA is partially 
excluding these systems, the term interim prohibition no longer 
applies. Therefore, EPA is rewording the title of Sec.  280.11 to 
Installation requirements for partially excluded UST systems. In 
addition, EPA is changing Sec.  280.11(a) to reflect that these 
requirements are installation requirements rather than prohibitions on 
installation.
    After considering comments and additional information, this final 
UST regulation excludes owners and operators of these tanks from 40 CFR 
part 280, subparts B (UST Systems: Design, Construction, Installation 
and Notification); C (General Operating Requirements); D (Release 
Detection); E (Release Reporting, Investigation, and Confirmation); G 
(Out-of-Service UST Systems and Closure); H (Financial Responsibility); 
J (Operator Training); and K (UST Systems with Field-Constructed Tanks 
and Airport Hydrant Fuel Distribution Systems). Owners and operators of 
these tank systems are still required to comply with subparts A 
(Program Scope and Installation Requirements for Partially Excluded

[[Page 41600]]

UST Systems) and F (Release Response and Corrective Action for UST 
Systems Containing Petroleum or Hazardous Substances).
    This final UST regulation also amends Sec.  280.10(c)(4) which 
refers to facilities licensed under 10 CFR part 50. This change is 
consistent with the regulatory citation listed in the Spill Prevention, 
Control, and Countermeasure provision in 40 CFR part 112 and also 
applies to installation of these tanks at NRC facilities in the future.

D. Other Changes

1. Changes to Overfill Prevention Equipment Requirements
    Through extensive stakeholder outreach, EPA identified vent line 
flow restrictors (also called ball float valves) as a significant 
concern for operability and safety. As a result, this final UST 
regulation modifies the 1988 UST regulation by eliminating vent line 
flow restrictors as an option for meeting the overfill prevention 
equipment requirement for new tank installations and when overfill 
prevention equipment is replaced. EPA makes this change to: reduce the 
frequency of UST releases due to operability issues, address system 
safety concerns, and address personnel safety concerns. Below are the 
issues:
     Operability--For a vent line flow restrictor to operate 
properly, the device must restrict the flow of regulated substance into 
the UST when the flow restrictor engages. If the tank top is not liquid 
or vapor tight, flow into the UST is not restricted because vapors 
continue to escape through non-tight areas. If vapors continue to 
escape from the UST, there is no pressure buildup in the vapor area of 
the tank, resulting in no reduced flow rate into the UST. Examples 
where non-tight tank tops may result in ineffective flow restrictors 
include: loose tank bungs or other tank top components; tanks with 
coaxial stage I vapor recovery installed; and tanks with both tank top 
and remote fill areas.
     System safety--Vent line flow restrictors can create 
safety concerns when they activate. USTs can become over pressurized 
and be damaged during deliveries when product is pumped into the tank. 
PEI's recommended practice for installation, RP 100, advises against 
using vent restriction devices because the vent line flow restrictor 
pressurizes the UST, creating a hazardous condition when the device 
operates as designed.
     Personnel safety--Delivery personnel can be sprayed with 
regulated substances when they disconnect the delivery hose from the 
fill pipe because pressure can build up in the tank when the vent line 
flow restrictor activates.
    Owners and operators may continue to use flow restrictors not in 
vent lines (such as flow restrictors in fill pipes), automatic shutoff 
devices, and high level alarms to meet the overfill prevention 
requirement for their UST systems.
    Owners and operators using a vent line flow restrictor before the 
effective date of this final UST regulation may continue using it to 
meet the overfill prevention requirement, as long as it operates 
properly by restricting the flow of regulated substances into the UST 
when the device activates. Flow restrictors in vent lines must be 
periodically inspected for proper operation according to section B-3, 
Overfill Prevention Equipment Inspections. This means that the flow 
restrictor will need to be accessible to the person inspecting the 
overfill prevention device. In addition, owners and operators may 
continue to use flow restrictors in UST system vent lines for reasons 
other than meeting the overfill prevention requirement, as long as the 
flow restrictors do not interfere with operation of the overfill 
prevention equipment being used.
    Most commenters supported this change to the 1988 UST regulation. 
Several even suggested requiring retrofits of vent line flow 
restrictors with another type of overfill prevention equipment. Because 
EPA is concerned about imposing too many additional costs on owners and 
operators of existing UST systems, EPA is not requiring retrofits of 
existing vent line flow restriction devices, as long as they operate 
properly, alert delivery personnel, and prevent overfills. Some 
commenters suggested EPA continue to allow the use of vent line flow 
restrictors if they meet the criteria set forth in PEI's RP 100. EPA 
reviewed the PEI recommended practice and noted that the code sets 
criteria for the allowed use of vent line flow restrictors. However, 
more importantly, the code advises against using vent line flow 
restrictors for overfill prevention under any circumstance because they 
pressurize the UST, creating a hazardous condition when the device 
operates as designed. Consistent with PEI's RP 100 advisory, EPA is not 
allowing owners and operators to use vent line flow restrictors in new 
tanks or when overfill prevention equipment is replaced. Finally, 
several commenters suggested EPA continue to allow the use of vent line 
flow restrictors, as long as the flow restrictor can be shown to 
operate effectively. Because it is difficult to determine if flow 
restrictors in vent lines will effectively restrict flow when the tank 
is close to being full, EPA is not allowing their use in new UST system 
installations or when overfill prevention equipment is replaced. 
However, the final UST regulation allows continued use of vent line 
flow restrictors installed before the effective date of the final UST 
regulation, as long as they operate properly, alert delivery personnel, 
and prevent overfills.
2. Internal Linings that Fail the Periodic Lining Inspection and Cannot 
Be Repaired
    About 3 percent of tanks rely on internal lining as the sole method 
of corrosion protection to meet the 1988 UST regulation.\104\ Tanks 
that were internally lined to meet the 1988 UST regulation corrosion 
protection requirement at Sec.  280.21 are typically older, bare steel 
tanks installed before 1986. The 1988 UST regulation preamble says that 
internal lining, when used as the sole method for corrosion protection, 
is not regarded as a permanent upgrade. However, it is adequate if the 
lining continues to meet original design specifications. If the 
internal lining no longer meets original design specifications and 
cannot be repaired according to industry codes, then the lined tank is 
subject to unprotected tank requirements and must be replaced after 
1998. However, this language, which was in the 1988 UST regulation 
preamble, was inadvertently omitted from the 1988 UST regulation.

---------------------------------------------------------------------------

    This final UST regulation modifies the 1988 UST regulation by 
requiring owners and operators to permanently close an UST that uses 
internal lining as the sole method of corrosion protection for the tank 
when the lining inspection determines the internal lining is no longer 
performing according to original design specifications and the internal 
lining cannot be repaired according to a code of practice developed by 
a nationally recognized association or independent testing laboratory. 
EPA understands that codes of practice for internal lining inspections 
in use as of publication of this final UST regulation contain pass or 
fail criteria for the internal lining and criteria for allowing repairs 
to an internal lining that fails the internal lining inspection.

[[Page 41601]]

    Owners and operators using internal lining as the sole method of 
corrosion protection for the tank may continue using that method as 
long as the internal lining is periodically inspected according to 
Sec.  280.21(b)(1)(ii) and the internal lining passes the inspection or 
is repaired so it meets original design specifications according to a 
code of practice developed by a nationally recognized association or 
independent testing laboratory.
    Consistent with current EPA policy,\105\ tanks using the 
combination of cathodic protection and internal lining for corrosion 
protection are not required to be closed if the internal lining fails 
and cannot be repaired, as long as the cathodic protection is operated 
and maintained according to Sec.  280.31 and the tank was assessed and 
found to be structurally sound and free of corrosion holes when the 
cathodic protection was added to the tank. In addition, owners and 
operators may use internal linings for purposes other than meeting 
EPA's corrosion protection upgrade requirement (for example, internal 
linings used for compatibility or secondary containment).
---------------------------------------------------------------------------

    \105\ EPA UST Technical Compendium Question And Answer # 14: 
www.epa.gov/oust/compend/nus.htm.
---------------------------------------------------------------------------

    Most commenters supported this change to the 1988 UST regulation. 
Some even suggested more restrictive requirements: either phasing out 
internal lining as a corrosion protection upgrade or permanently 
closing an UST if the lining inspection failed. EPA is not requiring 
these more restrictive approaches because we think internal lining 
repairs can be appropriate and protect the environment when conducted 
according to a code of practice developed by a nationally recognized 
association or independent testing laboratory. In addition, requiring 
permanent closure under these more restrictive circumstances would 
place additional financial burdens on UST owners and operators. Several 
commenters offered adding cathodic protection and relining the tank as 
alternatives to permanent closure. EPA is not including these options 
in this final UST regulation because internally lined tanks that fail 
the lining inspection and cannot be repaired according to a code of 
practice are generally older and are nearing or past the end of their 
useful lives.
3. Notification
    This final UST regulation adds a one-time notification of existence 
for UST systems with field-constructed tanks and UST systems identified 
as airport hydrant fuel distribution systems. In addition, it adds a 
new notification requirement for ownership changes; provides a new form 
for making notification of ownership changes; and makes minor changes 
to the notification language and notification form.
    EPA agrees with commenters who opposed requiring one-time 
notification of existence for emergency power generator UST systems as 
was proposed. Commenters explained, and EPA agrees, that since the 1988 
UST regulation deferred these systems only from the release detection 
requirements in subpart D, owners should have notified the appropriate 
implementing agency within 30 days of bringing an UST system into use 
in accordance with the notification requirements in subpart B. 
Therefore, in this final UST regulation, the requirement to submit a 
one-time notification of existence applies only to owners of UST 
systems with field-constructed tanks and airport hydrant fuel 
distribution systems. (This one-time notification of existence does not 
apply to wastewater treatment tank systems, UST systems containing 
radioactive material that are regulated under the Atomic Energy Act of 
1954, and UST systems that are part of an emergency generator system at 
nuclear power generation facilities regulated by the Nuclear Regulatory 
Commission under 10 CFR part 50 previously deferred in the 1988 UST 
regulation and partially excluded in this final UST regulation.)
    Furthermore, EPA agrees with commenters' requests to extend the 
time frame of 30 days in the 2011 proposed UST regulation for owners of 
UST systems with field-constructed tanks and airport hydrant fuel 
distribution systems to submit their one-time notification of 
existence. To provide owners more time for identifying and gathering 
information about these previously deferred systems, EPA is allowing 
owners of existing UST systems with field-constructed tanks and airport 
hydrant fuel distribution systems to submit a one-time notification of 
existence within 3 years of the effective date of this final UST 
regulation. EPA is requiring owners of UST systems with field-
constructed tanks and airport hydrant fuel distribution systems brought 
into use after the effective date of the final UST regulation to submit 
notification forms; this notification requirement has been in place 
since 1986 for all UST owners bringing new USTs into use. See subpart K 
for other requirements related to UST systems with field-constructed 
tanks and airport hydrant fuel distribution systems.
    Several commenters requested EPA allow 60 days instead of 30 days 
to submit a notification of ownership change, noting that the 30-day 
requirement is too stringent. One commenter stated that the time frame 
should be relaxed to account for large organizations where paperwork 
could involve a significant amount of time to process. Another stated 
that 30 days would be too short and unduly burdensome on small 
businesses. While EPA fully considered these comments, EPA thinks it is 
important for the ownership change notification requirement to be 
consistent with the new tank notification requirement (within 30 days 
of bringing an UST into use) in place since 1988. In addition, the 
ownership change notification form is shorter and takes less time to 
complete than the new tank notification form. As a result, this final 
UST regulation requires owners to submit a notification of ownership 
change within 30 days of assuming ownership of regulated UST systems.
    In this final UST regulation, EPA provides a new notification form 
titled Notification of Ownership Change for Underground Storage Tanks 
under appendix II. This form supplants the List of Agencies Designated 
to Receive Notifications in appendix II of the 1988 UST regulation. The 
list, published in 1988, contained agency names, addresses, and phone 
numbers, many of which are no longer accurate. EPA considered updating 
the list, but given the frequency with which contact information 
changes, decided it is pointless to publish information in the final 
UST regulation since it will quickly become obsolete. Rather, owners 
can obtain current agency contact information on EPA's Web site at 
www.epa.gov/oust.
    Two commenters indicated it was unclear who the implementing agency 
is and whether owners and operators need to notify both the state and 
EPA. In this final UST regulation, EPA is clarifying that owners must 
submit notification forms to the appropriate implementing agency. The 
term implementing agency is defined in the UST regulation and owners 
can obtain current contact and other information regarding their 
implementing agency on EPA's Web site at www.epa.gov/oust. In practice, 
EPA expects most owners will submit notification forms only to their 
respective state as their implementing agency, except in instances 
where the implementing agency is EPA. For example, EPA is the 
implementing agency for USTs located in Indian country; thus, owners 
with USTs in Indian country will submit their

[[Page 41602]]

notification forms to EPA. Owners should also be aware that individual 
states may have state versions of notification forms which owners 
should use instead when submitting to the implementing agency. EPA is 
revising the regulatory language in Sec.  280.22(a) and (b) and 
including language in subpart K to reflect that state forms may be used 
if the state requires owners to use notification forms that differ from 
those in appendices I and II.
    Lastly, EPA is amending the notification form in appendix I and the 
ownership change form in appendix II to incorporate comments regarding 
specific items on these forms. For example, two commenters noted that 
owners of previously deferred UST systems would be unable to complete 
the Certification of Installation section of the Notification for 
Underground Storage Tanks form because they were not subject to this 
requirement when the UST system was brought into use. In addition, 
records of installation for these previously deferred UST systems are 
likely to be nonexistent given the passage of time since installation. 
EPA agrees with these commenters and is revising the notification form 
to indicate that only owners of UST systems with field-constructed 
tanks and airport hydrant fuel distribution systems brought into use 
after the effective date of this final UST regulation need to complete 
this section.
4. Compatibility
Regulated Substance and Motor Fuel Definitions
    This final UST regulation revises the regulated substance 
definition to clarify that UST systems containing petroleum derived 
from non-crude oil products are regulated. The preamble to the 
supplement of the proposed 1988 UST regulation indicates that petroleum 
products can be derived from other materials, such as biomass, plant 
material, organic waste, coal, and shale oil.\106\ Petroleum is 
comprised of a complex blend of hydrocarbons regardless of its source 
material.
---------------------------------------------------------------------------

    \106\ ``40 CFR parts 280 and 281 USTs; Supplement to Proposed 
Rule,'' 52 FR 48640 (December 23, 1987).
---------------------------------------------------------------------------

    Many people applied the definition of regulated substance in the 
1988 UST regulation to petroleum UST systems only if the petroleum was 
derived from crude oil. This final UST regulation clarifies that 
petroleum derived from non-crude oil based products, such as green 
gasoline, is a regulated substance under 40 CFR part 280. This 
clarification is consistent with the preamble to the 1988 UST 
regulation, which indicates petroleum is not limited to being derived 
from crude oil.
    This final UST regulation also modifies the definition of motor 
fuel to better accommodate new motor fuels that may be marketed and 
stored in the future. The definition in the 1988 UST regulation listed 
motor fuel products. This led to confusion as to whether new fuels, 
such as petroleum blended with ethanol or biodiesel, are motor fuels. 
This final UST regulation clarifies the definition of motor fuel and 
explains that it is any fuel typically used to operate a motor engine. 
In addition, EPA received comments to change the motor fuel definition 
from petroleum and petroleum-based substances to a complex blend of 
hydrocarbons. EPA agrees that using the phrase complex blend of 
hydrocarbons eliminates ambiguity; it provides a clearer definition of 
motor fuel by including complex blends of hydrocarbons that may not be 
petroleum or petroleum-based. EPA is making this change in this final 
UST regulation.
Compatibility
    EPA understands that the chemical and physical properties of 
ethanol and biodiesel can be more degrading to certain UST system 
materials than petroleum alone. As the use of ethanol- and biodiesel-
blended fuels increases, EPA is concerned that not all UST system 
equipment or components are compatible with these fuel blends. For 
purposes of compatibility, EPA uses the term equipment to mean a group 
of components assembled together by the manufacturer. Compatibility can 
be determined for all components of a piece of equipment. Compatibility 
determinations for equipment are typically useful when an UST system is 
newly installed or when a complete piece of equipment is replaced. 
Examples of equipment include the piping system, STP assembly, and 
automatic shutoff device assembly. A component is considered an 
individual piece of an UST system and is typically a single piece of 
the equipment. Component compatibility is determined on a piece by 
piece basis. A component compatibility determination is typically 
needed when performing repairs on an UST system where only parts of a 
piece of equipment are replaced. Examples of components include 
gaskets, seals, and other individual pieces that form a piece of 
equipment.
    Gasoline containing 10 percent or less ethanol (E10) has been used 
in parts of the United States for many years. UST equipment and 
component manufacturers accommodated the E10 market by producing 
compatible equipment and components. According to the Renewable Fuels 
Association, ethanol is blended into over 90 percent of all gasoline 
sold in the United States,\107\ predominantly as E10. Recently, the 
United States has been moving toward use of higher blends of ethanol, 
due in part to federal and state laws encouraging increased use of 
biofuels. While most UST system equipment and components are compatible 
with E10, fuel blends containing greater than 10 percent ethanol do not 
have a long history of storage and may not be compatible with certain 
materials in existing UST systems. According to a 2011 report published 
by the U.S. Department of Energy's Oak Ridge National Laboratory,\108\ 
some elastomeric materials are particularly affected by intermediate 
ethanol blends and certain sealants may not be suitable for any 
ethanol-blended fuels. A 2007 report from Underwriters Laboratories 
(UL) \109\ evaluated the effect of 85 percent ethanol and 25 percent 
ethanol blends on dispenser components. Results indicated some 
materials used in the manufacture of seals degraded more when exposed 
to 25 percent ethanol test fluid than when exposed to 85 percent 
ethanol test fluid. Other literature suggests ethanol fuel blends can 
be more aggressive toward certain materials than independent fuel 
constituents, with maximum polymer swelling observed at approximately 
15 percent ethanol by volume.\110\ Based on this information, this 
final UST regulation clarifies the compatibility requirements for 
owners and operators storing regulated substances containing greater 
than 10 percent ethanol.

---------------------------------------------------------------------------

    This final UST regulation also clarifies the compatibility 
requirements for owners and operators storing regulated substances 
containing greater than 20 percent biodiesel. Although the total use of 
biodiesel is significantly less than that of ethanol, biodiesel has

[[Page 41603]]

become increasingly available across the United States and may be 
incompatible with certain materials in UST systems. For example, pure 
biodiesel (B100) has known compatibility issues with certain materials. 
According to the U.S. Department of Energy's National Renewable Energy 
Laboratory (NREL) Biodiesel Handling and Use Guide, Fourth 
Edition,\111\ ``B100 will degrade, soften, or seep through some hoses, 
gaskets, seals, elastomers, glues, and plastics with prolonged 
exposure. . . . Nitrile rubber compounds, polypropylene, polyvinyl, and 
Tygon[supreg] materials are particularly vulnerable to B100.''

and Use Guide, Fourth Edition, (2009). Available in the UST Docket 
under Docket ID No. EPA-HQ-UST-2010-0651.
---------------------------------------------------------------------------

    In contrast, the properties of very low blends of biodiesel, such 
as B5 or less, are so similar to those of petroleum diesel that the 
American Society for Testing and Materials (ASTM) International 
considers conventional diesel that contains up to 5 percent biodiesel 
to meet its Standard Specification for Diesel Fuel Oils.\112\ For 
biodiesel blends between 5 and 100 percent, there is very little 
compatibility information; however, NREL's handling and use guide 
concludes that biodiesel blends of B20 or less have less of an effect 
on materials and very low blends of biodiesel, such as B5 and B2, ``. . 
. have no noticeable effect on materials compatibility.'' \113\ In 
addition, fleet service sites have stored B20 in UST systems for years, 
and EPA is not aware of compatibility-related releases associated with 
those UST systems storing B20. Therefore, this final UST regulation 
requires tank owners and operators who store greater than 20 percent 
biodiesel in their UST systems demonstrate compatibility of UST 
equipment or components by one of the options listed in Sec.  280.32.

---------------------------------------------------------------------------

    This final UST regulation retains the requirement for owners and 
operators to use UST systems made of or lined with materials that are 
compatible with the substance stored in the UST system. It does not 
change the compatibility requirement in the 1988 UST regulation, but 
does add several options for owners and operators to demonstrate that 
their UST systems are compatible with regulated substances containing 
greater than 10 percent ethanol, greater than 20 percent biodiesel, or 
any other regulated substances identified by the implementing agency. 
Owners and operators of these UST systems must meet one of the 
following options:

 Use equipment or components that are certified or listed by a 
nationally recognized, independent testing laboratory for use with the 
fuel stored
 Use equipment or components approved by the manufacturer to be 
compatible with the fuel stored

    In addition, owners and operators may use another option determined 
by the implementing agency to be no less protective of human health and 
the environment than the methods listed above.
    These options provide owners and operators flexibility in 
demonstrating compatibility while still protecting human health and the 
environment. In the past, owners and operators typically demonstrated 
compatibility by using equipment or components certified or listed by a 
nationally recognized, independent testing laboratory, such as UL. Many 
pieces of UST equipment and components in the ground today were 
manufactured before regulated substances containing ethanol or 
biodiesel existed and are not approved by nationally recognized, 
independent testing laboratories for use with these fuel blends. 
Currently, certain tanks and piping have been tested and are listed by 
UL for use with higher-level ethanol blends. However, many other pieces 
of equipment and components of UST systems, such as leak detection 
devices, sealants, and containment sumps, may not be listed by UL or 
another nationally recognized, independent testing laboratory for use 
with these blends.
    In addition, EPA is not aware of any nationally recognized, 
independent testing laboratory that has performed compatibility testing 
on UST system equipment or components with biodiesel-blended fuels. 
Absent certification or listing from a nationally recognized, 
independent testing laboratory or other verification that the equipment 
or component may be used with anything other than conventional fuels, 
the suitability of an UST system for use with biodiesel blends is 
questionable. As a result, EPA is providing several options for 
demonstrating compatibility to reduce the risk of releases due to 
material incompatibility. Owners and operators storing regulated 
substances blended with greater than 10 percent ethanol or greater than 
20 percent biodiesel must meet the compatibility requirements before 
storing those regulated substances.
    For equipment and components tested and approved by a nationally 
recognized, independent testing laboratory, owners and operators may 
demonstrate compatibility solely by keeping records of the equipment 
and components. In this instance, the testing laboratory's listing, 
labeling, or approval demonstrates the equipment or component's 
suitability to be used with the regulated substance stored. This means 
owners and operators will be able to demonstrate compatibility by 
retaining equipment or component records.
    Owners and operators may also demonstrate compatibility by 
obtaining manufacturer's approval of the equipment or component. The 
manufacturer's approval must be in writing and include an affirmative 
statement that the equipment or component is compatible with the fuel 
blend stored. The manufacturer's approval must also specify the range 
of fuel blends for which the equipment or component is compatible. The 
manufacturer's approval must be issued from the equipment or component 
manufacturer, not another entity, such as the installer or distributor. 
A manufacturer's approval enables owners and operators to demonstrate 
compatibility for equipment or components not approved for use by a 
nationally recognized, independent testing laboratory. It also provides 
implementing agencies with verification that the equipment or component 
is compatible with the fuel stored.
    Implementing agencies may approve other options for complying with 
the compatibility requirement for regulated substances containing 
greater than 10 percent ethanol or greater than 20 percent biodiesel if 
they are no less protective of human health and the environment than 
manufacturer's approval or a listing, labeling, or approval by a 
nationally recognized, independent testing laboratory. This provides 
implementing agencies with flexibility to consider other approaches 
they determine to be appropriate. For example, in lieu of an 
affirmative compatibility determination, implementing agencies may 
allow secondarily contained UST systems using interstitial monitoring 
to store regulated substances containing greater than 10 percent 
ethanol or 20 percent biodiesel. The rationale is that a leak from the 
primary containment will be contained by secondary containment and 
detected by interstitial monitoring equipment before regulated 
substances reach the environment.
    Although these options for demonstrating compatibility apply to

[[Page 41604]]

UST systems storing regulated substances containing greater than 10 
percent ethanol and greater than 20 percent biodiesel, this final UST 
regulation extends the compatibility demonstration requirement to other 
regulated substances identified by implementing agencies. This provides 
implementing agencies with the flexibility to require a demonstration 
of compatibility if there are concerns about other existing regulated 
substances and when new regulated substances, such as biobutanol, enter 
the fuel market.
    EPA received comments about the difficulty in determining whether 
some UST system equipment or components currently installed in the 
ground are compatible with ethanol and biodiesel blended fuels. In 
fact, EPA thinks there are many cases where some equipment or 
components of UST systems in the ground as of 2014 are not compatible 
with newer fuels. Unless owners and operators specifically requested 
all of the UST system be compatible with higher ethanol or biodiesel 
blends, installers probably installed lower cost options for certain 
UST system equipment, such as a STP assembly, which may not be 
compatible with some newer fuels. Non-compatible equipment or 
components, such as equipment in containment sumps, are usually easier 
to upgrade or replace than the tank or piping because they are 
typically located in areas not requiring excavation. In addition, EPA 
provides various options for meeting the compatibility requirement. To 
protect the environment from releases of ethanol blends greater than 10 
percent, biodiesel blends greater than 20 percent, or any other 
regulated substance identified by the implementing agency, owners and 
operators must do one of the following:

 Demonstrate the UST system is compatible through certification 
or listing by a nationally recognized, independent testing laboratory 
or manufacturer approval
 Replace equipment or components not compatible or for which 
compatibility cannot be determined
 Use another option determined by an implementing agency to be 
no less protective of human health and the environment
 Not store these regulated substances in the UST system

    These options provide owners and operators with adequate 
flexibility when demonstrating compatibility and determining whether 
certain regulated substances may be stored in the UST system.
    Some commenters suggested adding other options owners and operators 
could use for determining compatibility. One suggested addition was 
certification by a professional engineer (P.E.), who would perform an 
on-site UST system analysis to determine compatibility. In order to 
perform this analysis, a P.E. would need to know the manufacturer and 
model of all UST system equipment or components. Because this 
information cannot be entirely obtained through visual observation, a 
P.E. would need to obtain records of the equipment to make an 
assessment and then search for relevant equipment listings or 
manufacturer certifications. This means a P.E. certification is 
equivalent to the options in this final UST regulation. EPA does not 
object to a P.E. performing a records review; however, we think it is 
impractical for a P.E. to perform a visual assessment of an UST system 
and make a compatibility determination in the absence of equipment 
records and certifications. Therefore, EPA is not explicitly allowing a 
P.E. to make a compatibility determination in the absence of UST system 
information and compatibility certifications.
    Some commenters suggested EPA use a tiered approach to demonstrate 
compatibility for UST systems storing regulated substances containing 
greater than 10 percent ethanol and greater than 20 percent biodiesel, 
and choose one method of determining compatibility. EPA interprets 
tiered approach to mean requiring the more stringent option first, 
which is listing by a nationally recognized, independent testing 
laboratory. If the more stringent option is not available, the second 
tier would allow manufacturer's approval. This final UST regulation 
does not include a tiered approach because EPA thinks using this method 
for demonstrating compatibility makes the final UST regulation too 
complicated for implementing agencies as well as owners and operators. 
Even if the UST system equipment or components have a listing from a 
nationally recognized, independent testing laboratory, we do not always 
know whether compatibility testing was part of the listing. EPA thinks 
manufacturers will only issue written claims of compatibility if they 
have sufficient information to support such claims.
    The 2011 proposed UST regulation required owners and operators 
retain these records:

 For all new and replaced equipment or components--so it is 
easier to demonstrate whether or not the equipment or component is 
compatible with the regulated substance stored
 For UST systems storing greater than 10 percent ethanol, 
greater than 20 percent biodiesel, or other regulated substance 
identified by the implementing agency--to demonstrate the UST system is 
compatible with these regulated substances or compliance with 
alternatives allowed by the implementing agency

    However, after careful consideration of comments, this final UST 
regulation does not require owners and operators maintain records for 
all new and replaced equipment. EPA decided it is too onerous for 
owners and operators to maintain this information, which may not 
transfer when facilities change ownership.
    To make it easier for UST owners and operators to comply with the 
compatibility requirement, this final UST regulation requires that 
owners and operators notify the implementing agency at least 30 days 
before switching to a regulated substance containing greater than 10 
percent ethanol, greater than 20 percent biodiesel, or any other 
regulated substance identified by the implementing agency. This 
notification prior to switching fuels gives the implementing agency an 
opportunity to inquire about the compatibility of the UST system before 
owners and operators begin storing the new regulated substance. This 
notification requirement already exists in some states. For example, 
Colorado, North Carolina, and South Carolina require UST owners submit 
a completed compatibility checklist prior to storing some newer fuel 
blends. To notify, owners and operators may contact implementing 
agencies via EPA's Web site at www.epa.gov/oust/.
    This final UST regulation requires owners and operators maintain 
records that demonstrate compliance with Sec.  280.32(b) for as long as 
the UST system stores greater than 10 percent ethanol, greater than 20 
percent biodiesel, or other regulated substances identified by the 
implementing agency. Owners and operators must retain records for these 
regulated substances in order to meet this compatibility requirement.
    The 2011 proposed UST regulation preamble included an extensive 
list of UST system equipment and components that must be compatible but 
that list was not in the 2011 proposed UST regulation. Based on 
commenter input, this final UST regulation includes a list of UST 
system equipment and components that owners and operators

[[Page 41605]]

must demonstrate to be compatible when using the manufacturer's 
approval and certification or listing options. The UST system equipment 
or components that owners and operators must demonstrate to be 
compatible are those related to the tank, piping, containment sumps, 
pumping equipment, release detection equipment, spill prevention 
equipment, and overfill prevention equipment. These items are a subset 
of an UST system, as defined by Sec.  280.12, which, if incompatible, 
could lead to a release.
    This changes protect human health and the environment from 
potential releases from incompatible UST systems. These changes are not 
overly burdensome, nor do they require costly retrofits. They give 
owners and operators flexibility, yet provide EPA with confidence that 
UST systems are compatible with new fuel blends when owners and 
operators use one or more of the options to determine compatibility. 
This final UST regulation provides owners and operators with certainty 
about which options are allowed for demonstrating UST system 
compatibility with the substances stored.
    Finally, EPA is removing from the compatibility section of the 1988 
UST regulation API Recommended Practice 1627, which is a code of 
practice related to methanol-blended fuels. EPA included this code of 
practice in the 1988 UST regulation to help owners and operators 
demonstrate compliance with the compatibility requirement for methanol-
blended fuels. However, EPA's subsequent review of this code revealed 
no substantial information about determining compatibility of UST 
systems with methanol-blended fuels. In August 2010, API published an 
updated version of API Recommended Practice 1626, which is a code of 
practice for storing and handling of ethanol-blended fuels. In the 2011 
proposed UST regulation, EPA removed this code of practice because the 
proposed UST regulation provided specific requirements about how owners 
and operators may demonstrate compatibility for their UST systems. 
However, because commenters pointed out the code of practice includes 
requirements for demonstrating compatibility of UST systems with 
ethanol-blended fuels, EPA is including it as a code of practice that 
may be useful in complying with the compatibility section in this final 
UST regulation.
5. Improving Repairs
Changes to the Definition of Repair
    This final UST regulation adds these UST system components to the 
definition of repair: piping; spill prevention equipment; overfill 
prevention equipment; corrosion protection equipment; and release 
detection equipment. The 1988 UST regulation definition of repair used 
the generic term UST system component and provided no detail about what 
an UST system component is. By adding these UST system components, EPA 
is making it clear that these specific components are subject to the 
repairs allowed section of the final UST regulation. This means owners 
and operators performing repairs on these UST system components must 
follow the repairs allowed section (Sec.  280.33).
    Owners and operators commonly fix UST components that have not 
caused a release of regulated substance from the UST system. However, 
the repair definition in the 1988 UST regulation did not consider these 
types of fixes as repairs since they were not associated with releases. 
This final UST regulation removes the link that a repair is only 
associated with a release, requiring owners and operators meet the 
repairs allowed section (Sec.  280.33) when fixing UST system 
components that have failed to function properly, even if they have not 
caused a release of product from the UST system. This change means 
owners and operators must perform repairs in accordance with a code of 
practice developed by a nationally recognized association or 
independent testing laboratory and test or inspect the repaired 
equipment. This change ensures repair activities separate from a 
release are conducted properly. For example, under the 1988 UST 
regulation, fixing a cathodic protection system was not considered a 
repair. In this final UST regulation, this activity is considered a 
repair that must meet the repair requirements in Sec.  280.33.
    EPA proposed adding a suspected release as part of the definition 
of repair, so repairs associated with suspected releases are covered 
under the repair definition. However, based on comments received, EPA 
is not including suspected release as part of the definition of repair 
in this final UST regulation because that circumstance is already 
covered under the ``failed to function properly'' language in the 
repair definition. EPA disagrees with commenters suggesting EPA remove 
the ``failed to function properly'' language because EPA thinks repairs 
need to occur both when a release occurs and when UST system equipment 
fails to function properly.
    Finally, based on comments received, EPA is adding clarifying 
language to the repair definition to ensure UST system component 
repairs restore components to proper operating condition.
Tests or Inspections After Repairs
    This final UST regulation adds new testing or inspection 
requirements for spill, overfill, and secondary containment equipment 
following a repair and allows owners and operators up to 30 days 
following the repair to test or inspect the repaired UST component. EPA 
acknowledges that some secondary containment can be tested through 
normal release detection if vacuum, pressure, or liquid-filled methods 
of interstitial monitoring are used as the method of release detection. 
In these cases, the secondary containment test occurs automatically, 
making it unnecessary to perform additional testing.
    EPA agrees with commenters about using the term inspecting rather 
than testing as it relates to the operability of overfill prevention 
equipment. Performing inspections will avoid potentially overfilling 
the tank while ensuring the overfill prevention equipment operates 
properly. EPA is revising the overfill prevention equipment test to be 
an overfill prevention equipment inspection.
    EPA agrees with commenters who indicated that testing or inspection 
following repair should only apply to the component or components 
repaired and not to the entire UST system. This final UST regulation 
requires testing or inspection, as appropriate, following a repair only 
for those UST system components repaired and not to all components at 
the UST site. In addition, EPA is requiring owners conduct a test of 
the secondary containment area (including containment sumps) only if 
the secondary containment area is repaired and that area is used for 
interstitial monitoring. Note that all secondary containment areas must 
use interstitial monitoring for tanks and piping installed 180 days 
after the effective date of this final UST regulation (see section A-2, 
Secondary Containment for additional information). Repairs to the 
primary containment areas of a tank or piping may be tested using other 
options for tanks and piping listed in the repairs section.
    Several commenters expressed concern that replacing UST system 
components that have not yet failed to function properly would trigger 
the repair requirements. If owners and

[[Page 41606]]

operators choose to replace UST system components, those components 
must meet the installation requirements in Sec.  280.20(d). Therefore, 
replaced UST system components do not have to meet the repair 
requirements in Sec.  280.33.
    EPA solicited comments about whether to consider requiring tests or 
inspections of spill, overfill, and secondary containment areas before 
returning the UST system to service, rather than within 30 days of the 
repair. Many commenters were supportive of requiring testing or 
inspection before bringing the UST system back into service. However, 
this final UST regulation allows owners and operators up to 30 days 
following the repair to conduct testing or inspections. EPA thinks 
owners and operators need to test or inspect the repaired component as 
soon as possible following the repair. However, EPA understands there 
are circumstances where testing or inspection before returning the UST 
system to service may be impractical (for example, weather conditions, 
remote locations, or the need to schedule a test). In these examples, 
the UST system would remain out of service until the test or inspection 
is completed, resulting in unnecessary UST system down time for owners 
and operators. Thirty days allows some flexibility for completing the 
test or inspection, while allowing the UST system to return to service.
6. Vapor Monitoring and Groundwater Monitoring
    This final UST regulation retains vapor monitoring and groundwater 
monitoring as methods of release detection for tanks and piping 
installed before the effective date of this final regulation, as long 
as owners and operators demonstrate proper installation and performance 
through a site assessment. In addition, this final UST regulation 
revises the recordkeeping requirement in Sec.  280.45, which means 
owners and operators must maintain site assessments according to Sec.  
280.43(e)(6) and (f)(7) for as long as these release detection methods 
are used.
    In the 2011 proposed UST regulation, EPA phased out vapor 
monitoring and groundwater monitoring over a five year time frame. 
However, EPA received significant comments in support of retaining 
these release detection methods. Many commenters presented 
circumstances where EPA should allow owners and operators to use vapor 
monitoring and groundwater monitoring such as: Until the system is 
replaced and the secondary containment requirement is triggered; or 
when the UST implementing agency already has or will establish 
additional criteria for use. In addition, commenters suggested EPA 
continue allowing certain UST systems to use vapor monitoring and 
groundwater monitoring, specifying emergency generator tanks, certain 
high-throughput UST systems, or specific low-throughput systems. EPA 
also received numerous requests to expand our proposed release 
detection options for airport hydrant fuel systems and field-
constructed tanks to allow the use of vapor monitoring or groundwater 
monitoring. Under the 2011 proposed UST regulation, these options are 
not acceptable release detection options for owners and operators of 
airport hydrant systems and field-constructed tanks.
    EPA agrees with commenters that owners and operators of emergency 
generator tanks, certain high-throughput UST systems, and specific low-
throughput systems could benefit from continued use of vapor monitoring 
and groundwater monitoring until owners and operators replace their UST 
systems to meet the secondary containment requirement necessitating 
interstitial monitoring. EPA thinks that requiring owners and operators 
to maintain the site assessment will increase environmental protection 
appreciably beyond the 1988 UST requirements. Implementing agencies 
have noted that site assessments often do not exist for vapor or 
groundwater monitoring. Thus, by requiring site assessment records, we 
will ensure vapor and groundwater monitoring wells are properly located 
and function as effective release detection. EPA also thinks that 
allowing these release detection options to be customized and used for 
airport hydrant systems and field-constructed tanks will make it easier 
for owners and operators to comply with the release detection 
requirement.
    Therefore, this final UST regulation continues to allow vapor and 
groundwater monitoring as long as owners and operators maintain a site 
assessment that demonstrates the release detection method meets the 
requirements in this final UST regulation. Owners and operators of 
airport hydrant systems and field-constructed tanks will have to meet 
the requirements for vapor monitoring and groundwater monitoring 
described in subpart K (see section C-2 for additional information).
    The 1988 UST regulation defined criteria for the use of both 
release detection methods as explicitly as possible, given the large 
variation of site-specific conditions at UST sites across the country. 
EPA supports UST implementing agencies' efforts to better define site 
assessment criteria specific to their local geology in addition to what 
is required in the UST regulation. EPA also acknowledges and supports 
several UST implementing agencies' efforts in conducting construction 
certification and recertification inspections. However, EPA has not 
analyzed the economic burden construction certification and 
recertification inspections would place on UST implementing agencies 
and potentially UST system owners and operators. Therefore, this final 
UST regulation does not require installation inspections, 
certification, or recertification inspections of monitoring wells. EPA 
expects UST implementing agencies will continue reviewing and accepting 
site assessments according to their program policies.
    In the event of a confirmed release at an UST site, vapor 
monitoring and groundwater monitoring are no longer acceptable options 
for release detection unless a new site assessment for the release 
detection method is conducted. If a release is confirmed, an owner and 
operator will have to remediate the site according to 40 CFR part 280, 
subpart F. Following site remediation, and as long as replacement of 
the UST system does not trigger the secondary containment requirement, 
an owner and operator must obtain a new site assessment to verify 
appropriate use of these methods, if the owner and operator chooses to 
continue using vapor monitoring or groundwater monitoring as the 
primary release detection method. Otherwise, owners and operators must 
use another method of release detection according to subpart D or 
subpart K.
    At the time of the 2011 proposed UST regulation, EPA estimated 
approximately 5 percent of all active UST systems were using vapor 
monitoring or groundwater monitoring to comply with release monitoring 
requirements.\114\ Commenters confirmed that 5 percent of vapor 
monitoring and groundwater monitoring was accurate. EPA also confirmed 
that although the methods are used very infrequently in the majority of 
jurisdictions, there is considerably high use in certain states. 
Arkansas, Louisiana, and Mississippi have a significant number of 
owners and operators using vapor monitoring, groundwater monitoring, or 
a combination of the two methods.

[[Page 41607]]

Estimated use of both methods in these states is 29 percent, 12 
percent, and 65 percent, respectively. Confirmation of high use in one 
particular geographic area of the country influenced EPA's decision to 
continue allowing use of these methods.

---------------------------------------------------------------------------

    EPA agrees with comments about major benefits for UST system owners 
and operators to use backup release detection, whether it is vapor 
monitoring, groundwater monitoring, or another method. However, neither 
the 1988 UST regulation nor this final UST regulation requires a 
secondary 30 day release detection method.
    EPA discussed several issues in the 2011 proposed UST regulation 
that prompted our proposal to no longer allow vapor monitoring and 
groundwater monitoring as primary methods of release detection. 
However, the requirement in this final UST regulation for owners and 
operators to maintain the record of a site assessment for as long as 
the method is used will address most of these issues.
    If the site assessment is available when inspecting USTs, UST 
implementing agencies can confirm proper installation and use of 
monitoring wells. For example, if inspectors find what they believe to 
be insufficient numbers of wells or wells improperly located to 
sufficiently monitor all portions of the tank or piping that routinely 
contain product, inspectors will be able to reference the site 
assessment to determine adequacy of the wells.
    The site assessment will also help UST implementing agencies 
determine whether certain conditions, which allow users to switch 
between vapor monitoring and groundwater monitoring due to seasonal 
variations, have been met. Monitoring wells must be properly 
constructed and installed to meet all criteria in Sec.  280.43(e) and 
(f). Wells used for vapor monitoring must allow vapors to collect; 
wells used for groundwater monitoring must be screened to prevent 
clogging and intercept the water table at both high and low groundwater 
conditions while being sealed from the ground to the top of the filter 
pack. Information regarding acceptability of the same wells used for 
both methods of release detection must be documented in the site 
assessment.
    In the 2011 proposed UST regulation, EPA discussed issues that were 
specific to vapor monitoring. These issues will be addressed when 
owners and operators maintain the site assessment for as long as the 
method is used. The site assessment will contain information on site 
conditions, such as whether porosity of the surrounding soil is 
sufficient. The site assessment will confirm that vapors to be 
monitored will be unaffected by groundwater, rainfall, or soil 
moisture. Perhaps the most crucial information in the site assessment 
is the background contamination level at the site. This will allow 
owners, operators, and implementing agencies to determine whether that 
level interferes with monitoring methods. It also marks the threshold 
for determining a release has occurred when monitoring for petroleum 
hydrocarbons.
    Maintaining the site assessment also addresses specific groundwater 
monitoring issues EPA discussed. Groundwater at times can be more than 
20 feet from the ground surface, due to seasonal water table 
variations. This can result in the depth to groundwater requirement not 
being met. Unless an analysis is performed and valid documentation 
regarding use of the wells for vapor monitoring during low water table 
conditions is included in the site assessment, the wells will be 
restricted for groundwater monitoring use only.
    In cases where there is no site assessment or an assessment does 
not sufficiently ensure requirements in Sec.  280.43(e) or (f) are met, 
UST system owners and operators must reassess the site and maintain 
documentation required in Sec.  280.43(e)(6) and (f)(7) in order to 
continue using groundwater or vapor monitoring as a method of release 
detection. At a minimum, a professional engineer or professional 
geologist, or equivalent licensed professional with experience in 
environmental engineering, hydrogeology, or other relevant technical 
discipline acceptable to the UST implementing agency must sign the new 
site assessment.
    EPA understands that in Arkansas, Louisiana, and Mississippi, where 
the methods are commonly used and account for the majority of use in 
the country, most UST system owners and operators or the UST 
implementing agency have sufficient documentation of the site 
assessment. This means most owners and operators in those states will 
not need to conduct a new site assessment to comply with this final UST 
regulation. Owners and operators in other areas of the country may need 
to conduct a site assessment in order to continue using vapor 
monitoring or groundwater monitoring.
    This final UST regulation also addresses another major aspect 
associated with vapor monitoring and groundwater monitoring methods. 
Equipment that is used as part of these release detection methods 
requires proper operation and maintenance in order to provide optimal 
monitoring results. Operation and maintenance requirements for 
electronic and non-electronic equipment are addressed in the release 
detection equipment testing requirement discussed in section B-5 and 
the walkthrough inspection requirement in section B-1, respectively.
7. Interstitial Monitoring Results, Including Interstitial Alarms, 
Under Subpart E
    This final UST regulation clarifies UST owners' and operators' 
responsibilities regarding interstitial monitoring results, including 
alarms, under 40 CFR part 280, subpart E. Specifically, EPA is making 
these changes:

 Sec.  280.50(b)--adding liquid in interstitial spaces of 
secondarily contained UST systems as an example of an unusual operating 
condition and adding to the list of criteria for not being required to 
report a suspected release that any liquid in the interstitial space 
not used as part of the interstitial monitoring method must be removed
 Sec.  280.50(c)--clarifying that an alarm during release 
detection monitoring is subject to the reporting requirement and 
describing exceptions to the reporting requirement
 Sec.  280.52(a)--adding owners and operators as appropriate 
must conduct secondary containment testing, and clarifying actions UST 
owners and operators must take if a test confirms a leak into the 
interstitial space or indicates a release to the environment

    The 1988 UST regulation implicitly covered interstitial monitoring 
when reporting suspected releases because it was a method of release 
detection. This final UST regulation makes changes to explicitly cover 
interstitial monitoring and reinforce that a leak into an interstitial 
space of a secondarily contained UST system also indicates a potential 
threat to the environment; leaks must be investigated, addressed, and 
as necessary, reported.
    This final UST regulation requires interstitial monitoring for all 
new or replaced tanks and piping (see section A-2, Secondary 
Containment). As new systems are installed, interstitial monitoring 
will become more widely used as a method of release detection. With 
this in mind, EPA wants UST owners and operators to clearly understand 
how interstitial monitoring results, including interstitial alarms, 
must be handled.
    In the 1988 UST regulation, EPA indicated that product or water in 
the

[[Page 41608]]

interstice, and alarms signifying the presence of those conditions, are 
unusual operating conditions and must be investigated appropriately. 
However, EPA did not indicate how UST owners and operators were to 
address discrepancies with interstitial spaces. As a result, some UST 
owners and operators were uncertain about how best to respond to 
interstitial monitoring results and alarms associated with interstitial 
monitoring that indicate a release may have occurred. To alleviate 
uncertainty for owners and operators, EPA provides information below 
about interstitial monitoring and responses to alarms.
    This final UST regulation revises Sec.  280.50(b) by adding 
interstitial spaces of secondarily contained UST systems and clarifying 
the presence of liquid in this space as an unusual operating condition 
unless the liquid is used for interstitial monitoring or meets the 
requirements described in Sec.  280.43(g)(2)(iv). Water in the 
interstitial space (presumably from a breach in the secondary wall) and 
product in the interstitial space (presumably from a breach in the 
primary wall) are the two typically encountered liquids discovered in 
the interstice. However, EPA is using the broader term liquid to cover 
water, product, or other substances in the liquid-phase in the 
interstitial space. Any liquid in this space not used for interstitial 
monitoring or not meeting the requirements described in Sec.  
280.43(g)(2)(iv) indicates there is an UST system problem that needs to 
be resolved. As a result, EPA is specifying this as an unusual 
operating condition and is requiring UST owners and operators 
investigate and address it.
    Several commenters suggested changes to Sec.  280.50(b) of the 2011 
proposed UST regulation. Suggestions included: Deleting that water or 
product in the interstice is reportable and clarifying the requirement 
that the unexplained presence of water or product is an unusual 
operating condition. Based on comments, EPA in Sec.  280.50(b) of this 
final UST regulation is using the term liquid, rather than water or 
product, to address any liquid in the interstitial space. To add 
clarity to this final UST regulation, EPA is also restructuring the 
section to provide subsections with separate examples of unusual 
operating conditions. This final UST regulation also allows owners and 
operators to not remove or report liquid under two conditions: Within 
secondary barriers described in Sec.  280.43(g)(2)(iv), as long as 
interstitial monitoring is not rendered inoperative, or the liquid is 
used as part of the interstitial monitoring method.
    EPA is clarifying in Sec.  280.50(c) that an alarm during release 
detection monitoring, which indicates a potential release or compromise 
of the interstitial space, is subject to the reporting requirement. UST 
owners and operators must appropriately address all release detection 
monitoring alarms. For example, some interstitial monitoring systems 
will trigger an alarm, which indicates a potential release or that the 
interstitial space has been compromised. In subpart E, EPA is adding 
interstitial monitoring to emphasize its importance because the 
secondary containment requirement for new and replaced systems in 
section A-2 will increase the use of interstitial monitoring. UST 
owners and operators are not required to report alarms from defective 
system equipment or components or alarms that are investigated and 
determined to be a non-release. Also, UST owners and operators do not 
have to report leaks, which are contained in the interstitial space; 
but owners and operators must investigate and repair problems. Except 
as provided in Sec.  280.43(g)(2)(iv), any liquid in the interstitial 
space not used as part of the interstitial monitoring method, such as 
brine filled, must be removed.
    Several commenters misunderstood EPA's discussion regarding 
reporting alarms. In the 2011 proposed UST regulation, EPA intended 
that owners and operators need to investigate all alarms, but only 
report confirmed releases and suspected releases that could not be 
ruled out by an investigation. Commenters suggested these changes to 
EPA's 2011 proposed UST regulation at Sec.  280.50(c): Deleting 
language pertaining to alarms; changing language regarding the time 
allowed to repair, recalibrate, or replace defective system equipment; 
and including an exception for reporting alarms that have been 
confirmed to be false alarms. Based on comments, EPA in Sec.  280.50(c) 
of this final UST regulation is expanding and describing exceptions to 
reporting monitoring results, including investigation of an alarm from 
a release detection method that indicates a release may have occurred.
    EPA is adding secondary containment testing, as appropriate, to the 
release investigation and confirmation steps in Sec.  280.52(a) of the 
final UST regulation. EPA thinks it is important to clarify actions UST 
owners and operators must take if a test confirms a leak into the 
interstitial space or indicates a release has occurred. If a leak into 
the interstice is confirmed, an UST owner and operator must correct or 
address the problem. In addition to options listed in the 1988 UST 
regulation, this final UST regulation includes closure as an option 
when an owner and operator confirms a release. Nothing in this final 
UST regulation changes the requirement in subpart F for an UST owner 
and operator to take corrective action if a release occurred.
    In the 2011 proposed UST regulation, EPA suggested that UST owners 
and operators follow integrity test requirements, now referred to as 
secondary containment testing, of the interstitial area. Many 
commenters noted that tank tightness testing or line tightness testing 
may be more appropriate tests to confirm a suspected release under 
certain circumstances, and UST system owners and operators should be 
allowed the choice of determining which test to use. EPA agrees and is 
revising Sec.  280.52(a) to indicate use of secondary containment 
testing as appropriate.
    EPA received several comments about the terms release and leak used 
throughout the 2011 proposed UST regulation and the 1988 UST 
regulation. Historically, EPA used these terms interchangeably. As a 
result of EPA's new secondary containment and interstitial monitoring 
requirement (see section A-2, Secondary Containment), there is now a 
subtle but important distinction between the terms. The term release is 
defined in the Solid Waste Disposal Act. EPA provides the same 
definition of release in the UST regulation at Sec.  280.12. Release 
means any spilling, leaking, emitting, discharging, escaping, leaching 
or disposing from an UST into groundwater, surface water or subsurface 
soils. A release always reaches the environment. The term leak in this 
final UST regulation is a more general term that includes both cases of 
when a regulated substance enters into a contained area (such as 
secondary containment) but has not yet reached the environment and when 
a regulated substance reaches the environment (a release). Therefore, 
the term release is a subset of the more general term leak. Note that 
leaks and releases have investigation and reporting requirements in 
subpart E.
    As a result of distinguishing between a leak and a release, EPA is 
clarifying the definition of release detection. The 1988 UST regulation 
defined release detection as determining whether a release of a 
regulated substance occurred from the UST system into the environment 
or into the interstitial space between the UST system and its secondary 
barrier or secondary

[[Page 41609]]

containment around it. This final UST regulation revises the definition 
of release detection to clarify regulated substances entering into the 
interstitial space are leaks instead of releases. This final UST 
regulation defines release detection as determining whether a release 
of a regulated substance occurred from the UST system into the 
environment or a leak occurred into the interstitial space between the 
UST system and its secondary barrier or secondary containment around 
it. This change allows EPA to continue to use the term release 
detection as it applies to both leaks and releases.

E. General Updates

1. Incorporate Newer Technologies
    Since EPA promulgated the 1988 UST regulation, newer tank, piping, 
and release detection technologies have been developed and are being 
used. EPA is incorporating several of these newer technologies in this 
final UST regulation. In addition, because the 1988 UST regulation 
closure requirements unintentionally restrict use of a newer tank 
within a tank technology, EPA is revising closure requirements to 
provide additional flexibility for implementing agencies to allow 
field-constructed tank technologies that construct a tank within an 
existing closed tank. However, EPA is not specifically including field-
constructed tank within a tank technologies in the new tank standards 
section in Sec.  280.20 of the final UST regulation, because the tank 
construction technologies currently covered in this section include 
both factory constructed and field-constructed technologies. Note that 
Sec.  280.20(d) requires new UST systems, including tank within a tank 
technologies, to be properly installed according to a code of practice 
developed by a nationally recognized association or independent testing 
laboratory and the manufacturer's instructions.
Clad and Jacketed Tanks
    This final UST regulation adds steel tanks that are clad or 
jacketed with a non-corrodible material to the list of specific new 
tank design and construction options for UST systems. EPA estimates 10 
percent of regulated tanks today are jacketed with a non-corrodible 
material and 18 percent are clad with a non-corrodible material.\115\

located in the docket EPA-HQ-UST-2011-0301.
---------------------------------------------------------------------------

    The 1988 UST regulation allowed a steel-fiberglass-reinforced-
plastic composite tank (also called a fiberglass clad tank), but did 
not specifically include other non-corrodible claddings. In addition to 
fiberglass, manufacturers in 2014 are using other non-corrodible 
materials claddings for steel tanks, which are listed by UL standard 
1746, External Corrosion Protection Systems for Steel Underground 
Storage Tanks. These tank technologies are effective at preventing 
corrosion of the portion of the steel tank shell in contact with the 
ground. EPA considers a cladding to be a non-corrosive dielectric 
material, bonded to a steel tank with sufficient durability to prevent 
external corrosion during the tank's life.
    Because they were not commonly used at the time, EPA did not 
include jacketed tanks in the 1988 UST regulation. These tanks are now: 
More commonly used; UL 1746 listed for external corrosion protection; 
and effective in preventing corrosion of the steel tank shell. EPA 
considers the tank jacket to be a non-corrosive dielectric material 
that: is constructed as secondary containment or jacketed around a 
steel tank; has sufficient durability to prevent external corrosion of 
the steel tank shell during a tank's life; and prevents a regulated 
substance released from the primary steel tank wall from reaching the 
environment.
Non-Corrodible Piping
    The 1988 UST regulation allowed fiberglass-reinforced plastic 
piping, but did not specifically include other non-corrodible piping 
options such as flexible plastic piping. Both fiberglass and flexible 
plastic piping are listed under the UL 971 standard, Nonmetallic 
Underground Piping for Flammable Liquids. Non-corrodible piping not 
made of fiberglass-reinforced plastic (in particular, flexible plastic 
piping) was installed at UST sites beginning in the 1990s and has 
evolved over the past 20 years. Flexible plastic piping is made of 
various non-corrodible materials, such as polyethylene and 
polyurethane. EPA estimates at least 13 percent of regulated piping 
currently installed is made of non-corrodible materials that are not 
fiberglass-reinforced plastic.\116\ This final UST regulation revises 
fiberglass-reinforced piping to be non-corrodible piping and allows UST 
owners and operators to install other types of non-corrodible piping, 
such as flexible plastic, without requiring implementing agencies to 
make a determination on the suitability of those materials.

---------------------------------------------------------------------------

Release Detection Technologies
    The 1988 UST regulation allowed UST owners and operators to use 
other methods that meet release detection performance criteria listed 
at Sec.  280.43(h). Although continuous in-tank leak detection (CITLD) 
and SIR were allowed under Sec.  280.43(h), EPA is including both by 
name and providing specific performance criteria in this final UST 
regulation for the reasons described below.
CITLD
    The 1988 UST regulation allowed ATG systems as a recognized method 
of release detection. However, ATG systems were generally listed with 
performance requirements consistent with performing a static test. ATG 
systems rely on system down time and the absence of product delivery or 
dispensing activities to perform release detection. In static testing 
mode, an ATG system analyzes product level and determines whether a 
leak is present during that down time. UST owners and operators also 
use ATG systems as a means of continually monitoring tanks for 
potential releases. CITLD has evolved as a reliable means of providing 
release detection equivalent to other methods specified in Sec.  
280.41. Within this category of methods, this final UST regulation 
allows continuous in-tank methods where the system incrementally 
gathers measurements to determine a tank's leak status within the 30-
day monitoring period.
    One commenter asked EPA to further clarify the term CITLD. That 
commenter said EPA presented language in the 2011 proposed UST 
regulation that confused CITLD, continuous statistical leak detection 
(CSLD), and SIR because each is a statistically based release detection 
method. EPA agrees with the commenter and is clarifying use of the term 
CITLD, which encompasses all statistically based methods where the 
system incrementally gathers measurements on an uninterrupted or nearly 
uninterrupted basis to determine a tank's leak status. Currently, there 
are two major groups that fit into this category: CSLD (also referred 
to as continuous automatic tank gauging methods) and continual 
reconciliation. Both groups typically use sensors permanently installed 
in the tank to obtain inventory measurements. They are combined with a 
microprocessor in

[[Page 41610]]

the ATG system or other control console that processes the data. 
Continual reconciliation methods are further distinguished by their 
connection to dispensing meters that allow for automatic recording and 
use of dispensing data in analyzing tanks' leak status. SIR, which we 
describe below, is not a continually operating method that fits into 
the CITLD category.
    This final UST regulation formally recognizes CITLD as a release 
detection method in Sec.  280.43(d). Per Sec.  280.41, a conclusive 
pass or fail result must be obtained within the 30-day monitoring 
period. All monitoring records must be maintained according to Sec.  
280.45. Another method of release detection is required in the event of 
an inconclusive result. For example, in the event of an inconclusive 
result, UST owners and operators may perform an in-tank static test 
using an ATG system or use another method of release detection.
SIR
    This final UST regulation adds SIR as a release detection method 
and provides performance criteria for its use. SIR must:
     Report a quantitative result with a calculated leak rate;
     Be capable of detecting a leak rate of at least 0.2 gallon 
per hour or a release of 150 gallons within a 30-day period with a 
probability of detection of not less than 0.95 and a probability of 
false alarm of no greater than 0.05; and
     Use a threshold that does not exceed one-half the minimum 
detectable leak rate.
    A quantitative result with a calculated leak rate is necessary to 
effectively perform release detection using SIR. Some SIR methods are 
qualitative based methods that simply provide a result of pass or fail 
without any additional information for UST owners and operators to 
gauge the validity of reported results. Based on information in the 
NWGLDE list,\117\ approximately 85 percent of SIR methods listed are 
quantitative-based methods. Many state UST implementing agencies 
already only allow quantitative methods. This final UST regulation only 
allows quantitative SIR as an option for meeting the release detection 
requirement.
---------------------------------------------------------------------------

Leak Detection Evaluations For Storage Tank Systems: https://www.nwglde.org/.
---------------------------------------------------------------------------

    Consistent with the performance criteria described in the other 
methods option for release detection, this final UST regulation 
maintains the performance standards of a 0.2 gallon per hour release or 
a release of 150 gallons within a 30-day period with a probability of 
detection of 0.95 and a probability of false alarm of 0.05. The 2011 
proposed UST regulation did not include the additional standard of 150 
gallons within a 30-day period for SIR. EPA agrees with the commenter 
who noted the importance of the 150 gallons criteria if SIR methods are 
used for monitoring piping for release detection; as a result, we are 
retaining this performance standard for SIR in the final UST regulation 
because EPA and some other implementing agencies allow UST system 
owners and operators to use SIR for piping release detection.
    Like other release detection methods, SIR must be capable of 
detecting a release of 0.2 gallon per hour or less with a probability 
of detection (Pd) of at least 0.95 and probability of false alarm (Pfa) 
of no more than 0.05. In a normal probability distribution, SIR data 
typically analyzed through the calculation of the reportable values of 
minimum detectable leak rate (MDL) and the leak declaration threshold 
(T) are related as follows:

 MDL is always greater than T
 Pd = (1-Pfa), then MDL = 2 times T (i.e., T = \1/2\ MDL)

    Any analysis of data indicating a threshold value greater than one-
half minimum detectable leak rate should be investigated as a suspected 
release.
    One commenter asked EPA to further clarify SIR. The commenter said 
EPA presented language in the 2011 proposed UST regulation that 
confused statistically based release detection methods currently in 
use. EPA agrees and is modifying the description of SIR in this final 
UST regulation at Sec.  280.43(h) to narrow the focus of statistically 
based methods, which fit under this section. SIR encompasses only those 
statistically based methods where inventory data is gathered over a 
period and typically provided to a vendor who analyzes the data to 
determine the leak status of the tank. These methods do not include 
systems that incrementally gather measurements on an uninterrupted or 
nearly uninterrupted basis to determine the tank's leak status 
described in Sec.  280.43(d) under continuous in tank leak detection.
    This final UST regulation addresses these issues associated with 
SIR:
 SIR is not the same as inventory control
    [cir] Historically, users, vendors, and regulators have incorrectly 
associated SIR with inventory control in Sec.  280.43(a). SIR is more 
sophisticated than inventory control and not subject to the same 
requirement to combine it with tank tightness testing and limit its use 
to 10 years. Section 280.50(c)(3) allows owners and operators to use a 
second month of inventory control data to confirm initial possible 
failure results. However, this allowance does not apply to SIR. 
Therefore, any failed SIR result must be investigated as a suspected 
release. Also, in the event of an inconclusive result, UST owners and 
operators must use another method of release detection to determine the 
leak status of the tank.
 Results for release detection, including SIR, are required 
within the 30-day monitoring period
    [cir] EPA considered including a requirement in the final UST 
regulation that UST owners and operators obtain a record of SIR results 
within 30 days. However, this requirement is already covered in the 
release detection requirements. As Sec.  280.41(a)(1) states, ``Tanks . 
. . must be monitored for releases at least every 30 days using one of 
the methods listed in Sec.  280.43(d) through (i) . . .'' In this final 
UST regulation, EPA is adding a subsection to formally recognize SIR. A 
definitive result of pass or fail that identifies the tank's leak 
status is required within the 30-day monitoring period for all release 
detection methods, including SIR.
 Owners and operators must use another method of release 
detection if SIR results are inconclusive
    [cir] For years, implementing agencies have been concerned about 
inconclusive results when using SIR for release detection. In 1993, EPA 
issued a policy regarding inconclusive SIR results,\118\ which says all 
methods used to meet release detection requirements in Sec.  280.41 
must obtain a conclusive result of pass or fail within the 30-day 
monitoring period. All monitoring records must be maintained according 
to Sec.  280.45. For SIR, this means UST owners and operators must 
obtain a report determining release status within the 30-day monitoring 
period. Another method of release detection is required when results 
are inconclusive; prior to sufficient data gathered to generate an 
initial report at startup; or when a report is not available for any 
month of

[[Page 41611]]

monitoring. Owners and operators have not performed release detection 
until the release status of the UST system has been conclusively 
determined.

21:https://epa.gov/oust/compend/rd.htm.
---------------------------------------------------------------------------

 Initial SIR report at startup
    [cir] SIR methods need to gather data over a period in order to 
determine whether the tank is leaking. In some cases, implementing 
agencies have addressed significant lag times between when data is 
collected and when a tank status determination is available to owners 
and operators. NWGLDE's list of third-party evaluated methods indicates 
the data collection period required for SIR methods ranges from 15 to 
90 days. However, most methods require between 23 and 30 days to gather 
sufficient measurements that provide an accurate result. Any method 
that goes beyond a 30-day monitoring period is inconsistent with and 
does not meet the release detection requirement. It is imperative that 
UST owners and operators determine the status of their tanks within the 
established monitoring period to avoid increased risk of releases. 
Therefore, owners and operators must use another release detection 
method at least once every 30 days until a SIR result is obtained. 
After that, owners and operators must have a SIR result at least once 
every 30 days.
 Meeting the 30-day monitoring requirement
    [cir] EPA received several comments regarding the lack of 
timeliness associated with determining whether a leak exists when using 
SIR. In many instances, monitoring results are not produced until the 
next monitoring period or well beyond. These commenters also provided 
several suggestions for EPA to address the lag time between UST owners 
and operators collecting leak detection data and receiving late 
reporting on the leak status of the tank. EPA reiterates its 
established regulatory requirement that tanks must be monitored for 
releases at least once every 30 days.
    [cir] Commenters provided other options for how owners and 
operators can meet the release detection requirement. One possible 
option is for EPA to require owners and operators perform a SIR 
analysis every 15 days using the last 30 days of data. This option 
results in a more frequent analysis of the UST system's leak status. 
EPA agrees this option would allow owners and operators to meet the 
release detection requirement. Another option suggested was for EPA to 
add a requirement that SIR results must be returned to owners within 
seven days of the end of the data collection period; other commenters 
indicated various other times. EPA disagrees with this option because 
it would not meet the requirement to conduct release detection at least 
once every 30 days. Providing additional time for one method to 
determine whether a leak has occurred would be both unfair to UST 
system owners and operators using other release detection methods, as 
well as result in decreased environmental protection. To meet the 
release detection requirement for SIR, owners and operators could 
conduct a more frequent analysis, as one commenter suggested, or send 
data more expeditiously by electronic means. EPA is retaining the 30-
day release detection requirement, which allows owners and operators to 
use whatever method they choose, as long as the method meets 
performance standards. UST system owners and operators can discuss 
changing their methods or data collection procedures with their SIR 
vendors in order to meet EPA's release detection requirement.
Interstitial Monitoring
    The 2011 proposed UST regulation included three methods of 
continuous interstitial monitoring--vacuum, pressure, and liquid-filled 
methods--in Sec.  280.43(g). EPA proposed these methods in conjunction 
with the periodic secondary containment testing requirement. Based on 
comments, EPA removed references to continuous interstitial monitoring 
in this final UST regulation. Because continuous interstitial 
monitoring is not discussed in this final UST regulation, EPA does not 
include language pertaining to continuous vacuum, pressure, or liquid-
filled methods of interstitial monitoring in Sec.  280.43(g). This does 
not impact release detection methods allowed under Sec.  280.43(g).
2. Updates to Codes of Practice Listed in the UST Regulation
    This final UST regulation updates the codes of practice (also 
called standards or recommended practices) listed in the 1988 UST 
regulation to reflect new codes, changes to code names, and new 
nationally recognized associations and independent testing 
laboratories. The 1988 UST regulation relied on codes of practice 
developed by nationally recognized associations or independent testing 
laboratories to implement many of the requirements. EPA will continue 
to rely on codes of practice in this final UST regulation.
    EPA reviewed information from more than 25 code making groups on 
more than 200 codes of practice, which have been developed or revised 
since the 1988 UST regulation.\119\ As a result, EPA is:

located in the docket EPA-HQ-UST-2011-0301.

 Updating titles and designations of existing codes of 
practice;
 Adding applicable codes of practice developed after the 1988 
UST regulation was finalized;
 Moving codes of practice that were misplaced in the 1988 UST 
regulation; and
 Removing codes of practice that:
    [cir] Are out of date, no longer available, withdrawn, or 
rescinded;
    [cir] No longer provide any information appropriate to or relevant 
to the final UST regulation where it was referenced; or
    [cir] Are no longer needed.

    For example, EPA listed the Association for Composite Tanks ACT-100 
tank standard in Sec.  280.20(a)(3) of the 1988 UST regulation as a 
code of practice for meeting the clad tank requirement. EPA is removing 
this code of practice from this final UST regulation because both the 
association and code of practice no longer exist.
    In several cases, EPA is moving a code of practice from one section 
of the final UST regulation to another. For example, EPA is moving 
Steel Tank Institute Standard F841, Standard for Dual Wall Underground 
Steel Storage Tanks from Sec.  280.43(g)--interstitial monitoring to 
Sec.  280.20(a)(2), which covers steel tanks. EPA thinks it makes more 
sense for this to be included under the UST design and construction 
standards, rather than as a release detection standard. EPA used 
similar rationale when relocating other codes of practice in this final 
UST regulation.
    As in the preamble to the 1988 UST regulation, this final UST 
regulation does not require use of a specific version or edition of any 
code. The consensus codes are frequently revised and updated. EPA 
recognizes that requiring use of the most recent edition of a code of 
practice would cause undue confusion in the regulated community. For 
example, owners and operators install UST systems according to codes

[[Page 41612]]

of practice current at the time of installation, but may not have 
equipment in the ground that meets codes that are current 10 years 
later. EPA concludes that the industry codes in effect at the date of 
publication of this final UST regulation are protective of human health 
and the environment. Using future editions of codes instead of editions 
now in effect is not required, but is encouraged; updated codes will 
probably provide for newer, more effective technologies and practices. 
Using past codes, which have been replaced by new editions prior to the 
effective date of this final UST regulation, is not allowed because 
some past recommended industry practices may not represent current 
codes of practice or may not adequately cover the regulatory 
requirement.
    Consistent with the preamble to the 1988 UST regulation, this final 
UST regulation interprets the term nationally recognized organization 
to mean a technical or professional organization that has issued 
standards formed by the consensus of its members. The organization 
should consider all relevant viewpoints and interests, including those 
of consumers and future or existing potential industry participants. 
The resulting standards should be widely accepted and based on a broad 
range of technical information, and performance criteria should be 
central elements of the resulting standards. EPA regards the following 
organizations, whose codes of practice are listed in this final UST 
regulation, as examples of nationally recognized organizations:

American Petroleum Institute (API)
American Society for Testing and Materials (ASTM)
Fiberglass Tank and Pipe Institute (FTPI)
National Association of Corrosion Engineers (NACE)
National Fire Protection Association (NFPA)
National Leak Prevention Association (NLPA)
Petroleum Equipment Institute (PEI) Steel Tank Institute (STI) 
Underwriters Laboratory (UL)
EPA received broad support for updating the codes of practice listed in 
the final UST regulation. Several commenters pointed out errors to 
titles or designations in the 2011 proposed UST regulation. This final 
UST regulation corrects these errors.

    EPA received comments on the 2011 proposed UST regulation asking 
that we add or remove several codes of practice. EPA reviewed PEI's 
recommended practice for testing and verification of spill, overfill, 
leak detection, and secondary containment equipment (RP 1200), and in 
this final UST regulation is including it in areas where testing or 
inspecting UST equipment is required. EPA also reviewed and is 
including PEI's recommended practice for the inspection and maintenance 
of UST systems (RP 900) in the walkthrough inspections portion of this 
final UST regulation. EPA is not including the Canadian code for 
installing fiber reinforced plastic linings (ULC/ORD-C58.4-05), because 
this final UST regulation no longer allows owners and operators to 
install internal linings to meet the corrosion protection upgrade. 
Owners may continue using internal linings for other reasons such as 
compatibility or secondary containment; but EPA determined there are no 
appropriate areas in this final UST regulation to list lining codes of 
practice for those purposes. Also, EPA is not including PEI's 
recommended practice for the inspection and maintenance of motor fuel 
dispensing equipment (RP 500), because it is a standard for inspecting 
motor fuel dispensing equipment and Subtitle I of the SWDA does not 
give EPA the authority to regulate aboveground equipment such as motor 
fuel dispensing equipment. Finally, EPA is not including STI's storage 
tank maintenance standard (R-111) as an option for periodic walkthrough 
inspections because the content of the 2011 version of this code of 
practice only focused on water and contaminants in the tank along with 
compatibility. Except for a monthly inspection checklist, this code of 
practice does not describe how to conduct a periodic walkthrough 
inspection. If STI changes this code of practice, implementing agencies 
may determine whether the newer version is adequate for meeting the 
periodic walkthrough inspection requirement in this final UST 
regulation.
    In the 2011 proposed UST regulation, EPA asked for input on whether 
the requirement to follow codes of practice and manufacturer's 
instructions under the installation requirements in Sec.  280.20(d) 
should apply to just tanks and piping (as stated in the 1988 UST 
regulation) or apply to the UST system as a whole. Both the 1988 UST 
regulation and this final UST regulation define UST system as the 
underground storage tank, connected underground piping, underground 
ancillary equipment, and containment system, if any. Commenters 
strongly supported requiring installation of the UST system, rather 
than just tanks and piping, according to a code of practice developed 
by a nationally recognized association or independent testing 
laboratory and according to manufacturer's instructions. For these 
reasons, this final UST regulation replaces tanks and piping with UST 
system in Sec.  280.20(d).
3. Updates To Remove Old Upgrade and Implementation Deadlines
    This final UST regulation removes references to the 1998 deadline 
and old phase in schedules, while continuing to allow testing of 
corrosion protection and release detection. These changes acknowledge 
that the 1998 deadline for upgrading UST systems with release 
prevention and the 1990s release detection and financial responsibility 
deadlines passed more than a decade ago. In addition, as of 2010 
implementing agencies have inspected all regulated UST systems at least 
once for compliance with release detection, release prevention, and 
financial responsibility requirements.
    EPA will no longer allow owners and operators to upgrade UST 
systems if they never met the 1998 upgrade requirements, unless the 
implementing agency determines the UST system is acceptable to upgrade. 
Owners and operators must permanently close non-upgraded UST systems 
according to the closure requirements in subpart G. Non-upgraded UST 
systems are older and have been in the ground for more than two 
decades. In addition, metal USTs and piping without corrosion 
protection pose a significant risk to human health and the environment, 
because unprotected metal in contact with soil corrodes. EPA is 
allowing implementing agencies to make case-by-case determinations on 
when to allow upgrades. EPA does not expect implementing agencies to 
allow continued use of tanks or piping not upgraded with corrosion 
protection. However, some implementing agencies may decide to allow 
owners and operators of UST systems with corrosion protection, but 
without spill or overfill prevention, to add spill or overfill 
prevention instead of requiring permanent closure.
    EPA will continue to allow UST systems with field-constructed tanks 
and airport hydrant systems to be upgraded with spill, overfill, and 
corrosion protection under subpart K of the UST regulation. See section 
C-2 for additional information on upgrading these UST systems.
    To meet the release detection requirement, Sec.  280.41 of the 1988 
UST regulation allowed owners and operators of USTs not upgraded with 
corrosion protection to use a

[[Page 41613]]

combination of monthly inventory control with annual tank tightness 
testing until December 22, 1998. Since owners and operators no longer 
have the option to use inventory control and annual tightness testing, 
EPA is removing this option from this final UST regulation.
    In response to comments received, EPA is removing the definition of 
petroleum marketing firm from subpart H of this final UST regulation. 
EPA only used the term petroleum marketing firm in the compliance dates 
section as it related to when these firms needed to meet the financial 
responsibility requirements. Since the compliance dates for 
conventional UST systems have passed more than a decade ago, the term 
no longer needs to be defined.
4. Editorial Corrections and Technical Amendments
    This final UST regulation includes editorial corrections and 
technical amendments to the 1988 UST regulation. Editorial corrections 
include: Correcting misspellings; capitalizing words; removing unused 
acronyms; using conventional number formatting; and appropriately 
referring to parts, subparts, sections, and paragraphs. In addition, 
this final UST regulation adds technical amendments, which include 
updating the final UST regulation to incorporate statutory changes that 
occurred since the 1988 UST regulation was promulgated and clarifying 
longstanding Agency interpretations and policies. EPA is making the 
following technical amendments in this final UST regulation:
     Sec.  280.10(c)(4)--EPA is revising the Nuclear Regulatory 
Commission citation to be consistent with the Spill Prevention Control 
and Countermeasures requirements in 40 CFR part 112. This final UST 
regulation partially excludes emergency generator systems at nuclear 
power generation facilities licensed by the Nuclear Regulatory 
Commission that are subject to Nuclear Regulatory Commission 
requirements regarding design and quality criteria, including but not 
limited to 10 CFR part 50. EPA originally proposed only deleting 
appendix A from the regulatory citation. However, EPA agrees with 
commenters that using language consistent with the Spill Prevention 
Control and Countermeasures requirements in 40 CFR part 112 provides 
clarity and consistency for owners and operators of emergency generator 
UST systems at nuclear power generation facilities.
     Sec.  280.12--EPA is revising exclusion (ii) of the 
definition of UST to incorporate a revision in section 9001 of the 
Solid Waste Disposal Act.
     This final UST regulation adds a technical amendment to 
Sec.  280.43(b), which codifies longstanding Agency policy adding 
additional flexibility for using manual tank gauging. This change 
updates UST capacity allowances and testing durations when using manual 
tank gauging. Since 1990, EPA allowed these deviations from the 1988 
UST regulation through policy and included them in outreach 
publications.
     The 2011 proposed UST regulation removed the requirement 
for inventory control for the automatic tank gauging release detection 
method in Sec.  280.43(d) because some interpreted the language as 
requiring both inventory control and automatic tank gauging. However, 
EPA agrees with commenters who indicated the language is necessary to 
ensure automatic tank gauging equipment meets inventory control 
performance standards in Sec.  280.43(a). More specifically, EPA is 
keeping the regulatory language to ensure owners and operators continue 
to measure for water as described in the inventory control requirement. 
This final UST regulation departs from the proposal and retains 
language established in the 1988 UST regulation that automatic tank 
gauging equipment also must meet the inventory control requirements. 
This final UST regulation does not require owners and operators to 
perform inventory control in addition to automatic tank gauging.
     This final UST regulation expressly states which new 
operation and maintenance requirements owners and operators do not have 
to meet for UST systems in temporary closure. Owners and operators of 
temporarily closed UST systems that are empty do not have to perform 
the following periodic release detection operation and maintenance 
testing and inspections in subparts C and D: 30 day release detection 
checks, annual sump checks, and annual hand-held release detection 
checks described in the walkthrough inspection section (see section B-
1); testing of containment sumps used for interstitial monitoring 
described in the secondary containment testing section (see section B-
4); and testing of release detection equipment described in the release 
detection equipment testing section (see section B-5). These 
requirements are unnecessary as long as the temporarily closed UST 
system is empty because release detection is not required in the first 
place. In addition, owners and operators of any UST system in temporary 
closure are not required to conduct the following periodic operation 
and maintenance testing and inspections for spill prevention equipment 
and overfill prevention equipment in subpart C: Spill prevention 
equipment testing (see section B-2); overfill prevention equipment 
inspections (see section B-3); or spill prevention equipment checks 
described in walkthrough inspections (see section B-1). Spill and 
overfill testing or inspections are not required for UST systems in 
temporary closure because those systems are not receiving deliveries of 
regulated substances. Finally, as a conforming amendment, this final 
UST regulation adds subpart K to the release detection citation because 
new release detection requirements for field-constructed tanks and 
airport hydrant systems are included in that subpart.
     This final UST regulation amends the definition of the 
term accidental release in Sec.  280.92 so it matches the definition 
described in the preamble to the 1988 UST regulation for the financial 
responsibility requirements (53 FR 43334). EPA intended the definition 
in the preamble to be included in the 1988 UST regulation, but failed 
to include the concept of releases as a result of operating the UST. 
Through this amendment, EPA is clarifying that owners and operators are 
required to have financial responsibility for releases arising from 
operating USTs (including releases due to filling USTs and releases 
occurring at dispensers).
     Sec.  280.94(a)(1)--EPA proposed to include the local 
government option citations in this section. However, those options are 
not included in this final UST regulation because they are already 
included in Sec.  280.94(a)(2).
     Sec.  280.97(b)(1) and (2)--EPA added the local government 
options as part of the reference since those options are also viable 
financial responsibility mechanisms.
     To make the local government bond rating test consistent 
with the requirements of the financial test in Sec.  280.94, this final 
UST regulation adds a new subsection to Sec.  280.104.
     To ensure the definition of UST technical standards in 
subpart I, Lender Liability, includes all of the preventative and 
operating requirements in this final UST regulation, EPA revised the 
definition to include subparts J and K as part of the preventative and 
operating requirements under 40 CFR part 280.
     To add clarity about the statement for shipping tickets 
and invoices in appendix III, this final UST regulation revises the 
appendix.
     Finally, the final UST regulation revises sections that 
use the terms operating life or properly closed to be permanently 
closed or when a change-

[[Page 41614]]

in-service occurs; this amendment will clearly indicate when the 
regulated operating life of an UST system ends. This final UST 
regulation does not define an operating life or proper closure. Rather, 
it describes permanent closure and change-in-service.

F. Alternative Options EPA Considered

    In developing this final UST regulation (hereafter the Selected 
Option), EPA considered and evaluated variations of a subset of the 
regulatory requirements using two alternative options (hereafter Option 
1 and Option 2). The table below highlights differences between the 
Selected Option and Options 1 and 2. Some of the regulatory 
requirements do not vary across the options (for example, notification 
of ownership changes is required in all three). As a result, regulatory 
changes discussed earlier in the preamble, but not listed here, mean 
those changes are in effect in all three options. Overall, Options 1 
and 2 consist of regulatory changes that are more and less stringent, 
respectively, than those of the Selected Option.

----------------------------------------------------------------------------------------------------------------
* In the 2011 proposed UST regulation, these regulatory changes generally consisted of more or stricter
  requirements than what is in the final UST regulation. For example, the 30-day walkthrough inspections in the
  2011 proposed UST regulation included monthly check of sumps. Please see the 2011 proposed UST regulation for
  details.

    Below we explain Options 1 and 2, as well as our rationale for 
each. (Note that EPA conducted a regulatory impact analysis for all 
three options. The results are discussed in the RIA document titled 
Assessment of the Potential Costs, Benefits, and Other Impacts of the 
Final Revisions to EPA's Underground Storage Tank Regulations, which is 
available in the docket for this action.)
EPA's Rationale for Option 1
    EPA considered keeping walkthrough inspections as described in the 
2011 proposed UST regulation. However, based on concerns from 
commenters regarding the proposed walkthrough inspection requirements, 
EPA decided to revise the components of the walkthrough inspection. See 
section B-1 for details regarding this final UST regulation on 
walkthrough inspections.
    EPA also considered requiring annual inspections of overfill 
prevention equipment, annual spill prevention equipment tests, and 
annual containment sump testing. After reviewing comments, considering 
the benefits of establishing one consistent implementation time frame 
across as many regulatory requirements as possible, as well as 
assessing the cost of requiring annual tests and inspections, EPA is 
requiring owners and operators inspect overfill prevention equipment 
and test spill prevention equipment and containment sumps once every 
three years. This balances the benefits of ensuring properly 
functioning equipment with the potential administrative burden and 
costs imposed on owners and operators.
    When considering operability checks for release detection 
equipment, EPA examined the possibility of keeping the operability 
checks as described in the 2011 proposed UST regulation. However, based 
on comments, EPA decided to revise some components of the operability 
checks. This resulted in allowing owners and operators to perform some 
release detection checks on an annual basis instead of every 30 days. 
See section B-5 for details regarding release detection equipment 
testing.
    EPA also considered maintaining the 2011 proposed option of a five 
year phase out of groundwater and vapor monitoring as permissible 
release detection methods. Based on concerns from states where 
groundwater and vapor monitoring are used frequently by owners and 
operators, EPA is retaining groundwater and vapor monitoring as long as 
owners and operators demonstrate proper installation and performance 
through a site assessment that must be maintained as long as the 
methods are used. See section D-6 for details regarding groundwater and 
vapor monitoring.
    EPA also considered maintaining its 2011 proposed requirements for 
release detection of emergency generator tanks and for demonstrating 
compatibility. However, as discussed in earlier sections (C-1 for 
emergency generator tanks and D-4 for compatibility), EPA is

[[Page 41615]]

revising these requirements in response to comments. For emergency 
generator tanks, we are revising the implementation time frame for 
consistency with other implementation dates. For compatibility, EPA is 
removing the recordkeeping requirement for new installations to make it 
easier for owners and operators to be in compliance. EPA is also adding 
a list of equipment that must demonstrate compatibility with storing 
ethanol blends greater than 10 percent or biodiesel blends greater than 
20 percent, or any other regulated substance identified by the 
implementing agency. This will help owners and operators understand 
which UST equipment must be demonstrated to be compatible.
    Lastly, EPA considered requiring owners and operators of airport 
hydrants systems and field-constructed tanks submit a one-time notice 
of existence in addition to reporting confirmed releases to the 
implementing agency. Owners and operators of these systems would not be 
subject to any additional regulatory requirements under Option 1. After 
weighing the availability of release detection options for these 
systems, the applicability of other requirements in this final UST 
regulation, and the potential human health and environmental impact of 
releases from these systems, EPA is fully regulating these systems. See 
C-2 for EPA's rationale for regulating airport hydrant systems and 
field-constructed tanks.
EPA's Rationale for Option 2
    In comparing costs with benefits of the final regulatory changes, 
EPA weighed different frequencies for walkthrough inspections and 
periodic equipment inspections or tests. EPA assessed quarterly 
walkthrough inspections, and not requiring overfill prevention 
equipment inspections and containment sump testing as ways to reduce 
potential cost impacts on owners and operators. Compared to the 30-day 
requirement, quarterly walkthrough inspections would reduce costs to 
owners and operators. However, EPA thinks a period less frequent than 
30 days for walkthrough inspections would considerably reduce benefits. 
High operator turnover and the frequency of deliveries both contribute 
to the need for 30-day walkthrough inspections. With that in mind, 
today EPA is requiring 30-day walkthrough inspections so owners and 
operators can consistently and routinely verify proper spill prevention 
and release detection performance. This will ensure problems are 
detected before a release occurs.
    EPA also considered not requiring overfill prevention equipment 
inspections and containment sump testing. However, as explained in 
sections B-3, Overfill Prevention Equipment Inspections and B-4, 
Secondary Containment Tests, tank overfills and containment sump areas 
account for a significant amount of releases from UST systems. As a 
result, EPA is requiring overfill prevention equipment inspections and 
containment sump testing (for containment sumps used for interstitial 
monitoring) once every three years. Overfill prevention equipment 
inspections will ensure overfill prevention equipment is operating 
properly. Similarly, containment sump testing will ensure that 
containment sumps used for interstitial monitoring will be liquid 
tight.
    To reduce total compliance costs of this final UST regulation for 
owners and operators, EPA considered allowing continued use of flow 
restrictors in vent lines (that is, ball float valves) as an acceptable 
form of overfill prevention equipment. After considering public 
comments, EPA maintains its position that vent line flow restrictors 
present problems for operability and safety reasons. As described in 
section D-1, EPA is eliminating ball float valves as an overfill 
prevention equipment option for all new tanks and when overfill 
prevention equipment is replaced in existing tanks.
    EPA considered maintaining the existing requirements for 
groundwater and vapor monitoring, in particular retaining the two as 
permissible release detection methods with no changes to the 1988 UST 
regulation. However, given the numerous concerns that have arisen over 
the years regarding these two release detection methods, such as 
misapplications and improper designs of monitoring wells, EPA is 
retaining these two release detection methods only if owners and 
operators demonstrate proper installation and performance through a 
site assessment. See section D-6 for details regarding groundwater and 
vapor monitoring.
    EPA also considered only retaining the current requirement for 
owners and operators to use UST systems made of or lined with materials 
that are compatible with the substance stored in the UST system. 
However, EPA understands that the chemical and physical properties of 
ethanol and biodiesel can be more degrading to certain UST materials 
than petroleum alone. As the use of ethanol- and biodiesel-blended 
fuels increases, EPA is concerned that not all UST system equipment or 
components are compatible with these fuels. Therefore, EPA is requiring 
owners and operators demonstrate compatibility of certain UST system 
components when storing ethanol blends greater than 10 percent and 
biodiesel blends greater than 20 percent. Owners and operators can 
demonstrate compatibility of required components by using one of the 
three options described in this final UST regulation. See section D-4 
for details regarding compatibility.
    Finally, EPA considered maintaining deferrals for airport hydrant 
systems and field-constructed tanks. However, as explained above, after 
weighing the availability of release detection options for these 
systems, the applicability of the other requirements in this final UST 
regulation, and the potential human health and environmental impact of 
releases from these systems, EPA is fully regulating these systems. See 
C-2 for EPA's rationale for regulating airport hydrant systems and 
field-constructed tanks.

V. Updates to State Program Approval Requirements

    EPA is making changes to the 1988 SPA regulation (40 CFR part 281) 
to make it consistent with certain Energy Policy Act requirements and 
certain revisions to the 1988 UST regulation (40 CFR part 280). 
Commenters generally supported EPA changing portions of the 1988 SPA 
regulation and making it consistent with revisions to the 1988 UST 
regulation. Commenters supported EPA keeping the general format of the 
1988 SPA regulation and not making the final SPA regulation as explicit 
or prescriptive as this final UST regulation.
    EPA is making these substantive changes to the 1988 SPA regulation.

 Sec.  281.12(b)--adding definitional exceptions for several 
Energy Policy Act definitions
 Sec. Sec.  281.30(a), 281.33(c)(2), and 281.33(d)(3)--require 
secondary containment for new or replaced tanks and piping and under-
dispenser containment for new motor fuel dispenser systems for UST 
systems located within 1,000 feet of a potable drinking water well or 
community water system, unless a state requires manufacturer and 
installer financial responsibility according to section 9003(i)(2) of 
the Solid Waste Disposal Act
 Sec. Sec.  281.30(a)(1) and 281.33(d)(3)--exclude safe suction 
piping, airport hydrant system piping, and field-constructed tank 
piping from being required to meet the secondary containment and 
interstitial monitoring requirements

replaced overfill prevention
 Sec.  281.30(c)--add notification for ownership changes
 Sec. Sec.  281.31 and 281.33(b)--delete upgrading requirements 
and eliminate phase-in schedule; add phase-in schedule for airport 
hydrant fuel distribution systems and UST systems with field-
constructed tanks
 Sec.  281.32(c)--add requirement for states to include 
provisions for demonstrating compatibility with new and innovative 
regulated substances or other regulated substances identified by 
implementing agencies or include other provisions determined by the 
implementing agency to be no less protective of human health and the 
environment than the provisions for demonstrating compatibility
 Sec. Sec.  281.32(e) and (f) and 281.33(a)(3)--add periodic 
testing or inspection of spill and overfill prevention equipment, 
containment sumps used for interstitial monitoring of piping, and 
mechanical and electronic release detection components; and operation 
and maintenance walkthrough inspections, as well as maintaining 
associated records
 Sec.  281.33(c)--limit use of monthly inventory control in 
combination with tank tightness testing conducted every five years for 
the first ten years after the tank is installed or upgraded, if the 
tank was installed prior to a state receiving SPA
 Sec.  281.33(e)--require hazardous substance USTs to only use 
secondary containment with interstitial monitoring
 Sec.  281.34(a)(1)--add interstitial space may have been 
compromised to suspected releases
 Sec.  281.37--eliminate phase-in requirement for financial 
responsibility
 Sec.  281.39--require operator training according to Sec.  
9010 of the Solid Waste Disposal Act
 Sec.  281.41(a)(4)--add authority to prohibit deliveries

    EPA is making these technical changes to the SPA regulation.

 Sec.  281.10--change subpart to part
 Sec. Sec.  281.11(c), 281.20(d), 281.21(a)(2), 281.23, 
281.50(a), and formerly Sec.  281.51--eliminate interim approval
 Sec.  281.12(a)(2)--change Indian lands to Indian country
 Formerly Sec.  281.32(e)--eliminate requirement to maintain 
upgrade records
 Formerly Sec.  281.38--eliminate reserved section for 
financial responsibility for USTs containing hazardous substances
 Move Sec.  281.39 to Sec.  281.38--Lender Liability
 Sec. Sec.  281.50(e) and 281.51(c)(1)--clarify how to provide 
public notice to attract statewide attention
 Sec.  281.51, formerly Sec.  281.52--add requirement for 
approved states to submit a revised application within three years of 
40 CFR part 281 changes that require a program revision
 Sec.  281.61--move Sec.  281.60(b) to Sec.  281.61(b)(2)

Background Information

    The 1988 SPA regulation in 40 CFR part 281 sets criteria state UST 
programs must meet to receive EPA's approval to operate in lieu of the 
federal UST program. The 1988 SPA regulation sets performance criteria 
states must meet to be considered no less stringent than the federal 
UST regulation (hereafter 40 CFR part 280) and provides requirements 
for states to have adequate enforcement. It also details the components 
of a SPA application.
    EPA is changing the 1988 SPA regulation and making it consistent 
with this final UST regulation. By doing so, EPA will require states to 
adopt requirements similar to the final UST regulation, in order to 
obtain or retain SPA. Commenters supported maintaining the general 
format of the 1988 SPA regulation and EPA is keeping that general 
format. We are not making this final SPA regulation as explicit or 
prescriptive as this final UST regulation. Finally, EPA is making 
technical corrections and adding a deadline for states to apply for 
revised state program approval.

Addressing Energy Policy Act Requirements and 40 CFR Part 280 Changes

How SPA Works
    This final UST regulation primarily impacts the 1988 SPA regulation 
in 40 CFR part 281, subpart C--Criteria for No Less Stringent. As of 
2014, 40 states, including the District of Columbia and Puerto Rico, 
have state program approval and state UST requirements apply in lieu of 
the federal requirements. To ensure these jurisdictions and any other 
states or territories obtaining SPA adopt these 40 CFR part 280 
changes, EPA must update the 1988 SPA regulations in 40 CFR part 281, 
subpart C--Criteria for No Less Stringent. To continue providing states 
with flexibility and not disrupt current state programs, EPA is 
revising the 1988 SPA regulation to make it consistent with, but not 
identical to, the 40 CFR part 280 changes. Instead, EPA is making 
changes to the 1988 SPA regulation in a less prescriptive manner than 
the changes to 40 CFR part 280. Since 1988, this approach has proven a 
successful way to implement the UST program and provide environmental 
protection.
    The 1988 SPA regulation developed no less stringent criteria in the 
form of objectives.\120\ EPA is continuing this format so that, taken 
as a whole, state programs will be no less stringent than the federal 
requirements, even though state programs may deviate slightly from what 
is explicitly required in 40 CFR part 280. For example, Sec.  281.30 
covers the no less stringent requirement for new UST system design, 
construction, and installation; it corresponds to Sec.  280.20 of this 
final UST regulation, but is much less explicit about requirements.
---------------------------------------------------------------------------

    \120\ 53 FR 37216, September 23, 1988.
---------------------------------------------------------------------------

    According to Sec.  281.30 and in order to receive SPA, a state must 
require all new UST systems ``. . . [b]e designed, constructed, and 
installed in a manner that will prevent releases for their operating 
life due to manufacturing defects, structural failure, or corrosion . . 
.''. In contrast, Sec.  280.20 is much more explicit about how tank 
owners and operators ensure their tanks and piping prevent releases. It 
states what is required to prevent releases and provides codes of 
practice to comply. Although Sec.  281.30 is less explicit, it 
nonetheless ensures owners and operators in approved states install UST 
systems that prevent releases and provides states flexibility in 
achieving that goal.
Goal Oriented Changes
    EPA is making goal oriented changes to subpart C--Criteria for No 
Less Stringent. By the term goal oriented changes, EPA means changes in 
which states have some flexibility as to how they meet the goals of 
particular sections of the final SPA regulation. These changes reflect 
certain 40 CFR part 280 changes.

 Sec.  281.30(c)--add notification for ownership changes
 Sec. Sec.  281.31 and 281.33(b)--add a phase-in schedule for 
upgrading previously deferred airport hydrant fuel distribution systems 
and UST systems with field-constructed tanks
 Sec.  281.32(c)--add requirement for states to include 
provisions for demonstrating compatibility with new and innovative 
regulated substances or other regulated substances identified by 
implementing agencies

[[Page 41617]]

or include other provisions determined by the implementing agency to be 
no less protective of human health and the environment than the 
provisions for demonstrating compatibility
 Sec. Sec.  281.32(e) and (f) and 281.33(a)(3)--add periodic 
testing or inspection of spill and overfill prevention equipment, 
containment sumps used for interstitial monitoring of piping, and 
mechanical and electronic release detection components; and operation 
and maintenance walkthrough inspections, as well as maintaining 
associated records

    The ownership change notification in Sec.  280.22 requires anyone 
who assumes ownership of an UST system to notify the implementing 
agency within 30 days of assuming ownership and specifies what 
notification must include. However, the SPA regulation change in Sec.  
281.30(c) is much less prescriptive and indicates that states require 
owners and operators to ``. . . notify the implementing state agency 
within a reasonable time frame when assuming ownership of an UST 
system.'' This provides states some flexibility in complying, including 
allowing them to continue relying on an annual tank registration 
program to meet this requirement. This is a reasonable way to ensure 
states know who owns USTs in their jurisdictions. EPA does not have an 
annual UST registration program, so we specify a time frame in Sec.  
280.22 because we want to know who owns tanks in jurisdictions where we 
are the implementing agency.
    EPA is requiring that previously deferred airport hydrant fuel 
distribution systems and UST systems with field-constructed tanks meet 
specific upgrade requirements in subpart K. This is one way that states 
can achieve compliance with Sec.  281.31, which requires states ensure 
tanks are upgraded to prevent releases due to corrosion, spills, and 
overfills or be permanently closed. EPA concludes these more general 
requirements are sufficient for a state program to protect human health 
and the environment because they require UST systems to ``. . . prevent 
releases for their operating life. . . .'' EPA thinks it is also 
adequate to upgrade previously deferred systems to this standard.
    Additionally, EPA is requiring airport hydrant systems, field-
constructed tanks, and emergency generator tanks be upgraded within 
three years of the effective date of the state requirements. For states 
which did not defer these systems or already had their requirements in 
place before the effective date of this final SPA regulation, the three 
year requirement does not apply. In the past, EPA experienced issues 
with requiring states to have a particular requirement by a certain 
date in order to receive SPA. States applying for SPA after a deadline 
passed often had difficulty implementing or obtaining a retroactive 
requirement. EPA understands that states may have given owners and 
operators of UST systems previously deferred by EPA different time 
periods than three years to initially meet their requirements.
    In Sec.  281.32(c), EPA is adding a requirement for states to 
include provisions for demonstrating compatibility with new and 
innovative regulated substances or other regulated substances 
identified by implementing agencies or include other provisions 
determined by the implementing agency to be no less protective of human 
health and the environment than the provisions for demonstrating 
compatibility. EPA is concerned about the compatibility of new and 
innovative fuels with the existing UST system infrastructure. We added 
to Sec.  280.32 methods for demonstrating compatibility of UST systems 
with certain ethanol and biodiesel blends in response to this concern. 
State UST implementing agencies also need to ensure owners and 
operators only store regulated substances compatible with their UST 
systems. Requiring states have provisions in place for storing new and 
innovative regulated substances in order to receive SPA ensures states 
are taking appropriate steps to ensure compatibility of the UST system 
with a rapidly expanding spectrum of traditional and new and innovative 
fuels.
    This final UST regulation adds various UST operation and 
maintenance requirements. In 40 CFR part 280, EPA is requiring specific 
frequencies and procedures for testing or inspecting spill and overfill 
prevention equipment, testing containment sumps used for interstitial 
monitoring of piping, testing release detection equipment, and 
conducting operation and maintenance walkthrough inspections. According 
to Sec.  281.32, states must require these tests or inspections in a 
manner and frequency that ensures proper functionality of equipment, 
includes proper operation and maintenance of the UST system, and 
prevents releases for the life of the equipment and UST system. EPA 
thinks this approach allows states that implement these requirements 
despite different frequencies or manners, to receive SPA, as long as 
their requirements sufficiently ensure properly functioning non-
releasing UST systems. EPA is updating Sec.  281.32(g) by adding these 
activities to the recordkeeping requirements of SPA.
Energy Policy Act Changes
    In this final SPA regulation, EPA is addressing Energy Policy Act 
requirements more generally than in this final UST regulation; however, 
the Energy Policy Act requirements are slightly different than the goal 
oriented approach discussed above. The Energy Policy Act amends the 
Solid Waste Disposal Act and requires states, which receive federal 
Subtitle I money, to adopt operator training requirements, delivery 
prohibition, and additional measures to protect groundwater from 
contamination. In the additional measures to protect groundwater 
provision, states must require either secondary containment and 
interstitial monitoring for new or replaced tanks and piping within 
1,000 feet of a potable drinking water well or community water system, 
or manufacturer and installer financial responsibility and installer 
certification. The secondary containment requirement includes under-
dispenser containment on any new motor fuel dispenser system within 
1,000 feet of a potable drinking water well or community water system.
    EPA developed guidelines for states to implement the Energy Policy 
Act requirements; many states implemented the Energy Policy Act 
requirements according to these guidelines. In order to impose similar 
requirements in Indian country and in states that do not adopt Energy 
Policy Act requirements, EPA is adding secondary containment and 
operator training to these 40 CFR part 280 requirements. However, it is 
not EPA's intent to supersede programs states developed to meet Energy 
Policy Act requirements.
    Several commenters had concerns about the Energy Policy Act 
provisions. Seven commenters wanted to ensure states only have to meet 
Energy Policy Act grant guidelines and do not have to change their 
regulations to mirror the 40 CFR part 280 requirements in order to 
obtain SPA. These commenters were also concerned that EPA requirements 
for secondary containment and operator training could be considered 
more stringent than state requirements that met the grant guidelines. 
EPA agrees that requiring states to alter newly implemented provisions 
could cause unnecessary work for states and UST owners. Therefore, this 
final SPA regulation explicitly addresses the secondary containment, 
manufacturer and installer financial responsibility

[[Page 41618]]

and installer certification, delivery prohibition, and operator 
training requirements that appear in the Energy Policy Act. EPA agrees 
that it is not necessary for states already meeting these Energy Policy 
Act requirements to change their programs in order to receive or retain 
SPA. EPA was unable to incorporate a similar requirement in 40 CFR part 
280, so states will need to obtain SPA in order to ensure there is no 
difference between state and federal requirements with respect to 
Energy Policy Act requirements.
    EPA is adding definitional exceptions in Sec.  281.12(b). This 
final SPA regulation allows states to use definitions associated with 
tank and piping secondary containment and operator training that are 
different than those in 40 CFR part 280 as long as those definitions 
are consistent with definitions described in sections 9003 and 9010 of 
the Solid Waste Disposal Act. This change provides states with 
additional flexibility in defining key terms.
    EPA is adding additional measures to protect groundwater and is 
adding operator training requirements in subpart C (Sec. Sec.  
281.22(d)(3), 281.30(a), 281.33(c)(2), and 281.39). Delivery 
prohibition is in subpart D--Adequate Enforcement of Compliance (Sec.  
281.40(a)). Because delivery prohibition is an enforcement option, EPA 
is requiring states have authority to prohibit deliveries according to 
the Energy Policy Act and EPA's grant guidelines, rather than make this 
a no less stringent requirement.
    EPA is not adding delivery prohibition to 40 CFR part 280 because 
delivery prohibition is primarily an enforcement option for 
implementing agencies; it is not a requirement for owners and 
operators. Because the Energy Policy Act gives EPA clear delivery 
prohibition enforcement authority, we do not need to add delivery 
prohibition to this final UST regulation. However, the only way to 
ensure states have that same authority is to require states implement 
delivery prohibition as a prerequisite for SPA, as required in Sec.  
281.40(a).
Specific Changes
    EPA is making the changes listed below to subpart C--Criteria for 
No Less Stringent to reflect changes made in 40 CFR part 280. These 
changes ensure states adopt the changes made in 40 CFR part 280 and are 
able to receive SPA.

 Sec. Sec.  281.30(a)(1) and 281.33(d)(3)--exclude safe suction 
piping, airport hydrant system piping, and field-constructed tank 
piping from being required to meet the secondary containment and 
interstitial monitoring requirements
 Sec.  281.30(b)--eliminate flow restrictors for new or 
replaced overfill prevention
 Sec.  281.31--delete upgrading requirements
 Sec.  281.33(c)--limit use of monthly inventory control in 
combination with tank tightness testing conducted every five years for 
the first ten years after the tank is installed or upgraded, if the 
tank was installed prior to a state receiving SPA
 Sec.  281.33(e)--require hazardous substance USTs to only use 
secondary containment with interstitial monitoring
 Sec.  281.34(a)(1)--add ``. . . interstitial space may have 
been compromised . . .'' to suspected releases
 Sec.  281.37--eliminate phase-in requirement for financial 
responsibility

    In Sec. Sec.  281.30(a)(1) and 281.33(d)(3) EPA is not requiring 
safe suction piping, airport hydrant system piping, and piping 
associated with field-constructed tanks greater than 50,000 gallons in 
capacity to meet the secondary containment and interstitial monitoring 
requirements. Suction piping that meets the requirements of Sec.  
281.33(d)(2)(ii) has characteristics that ensure little, if any, 
regulated substances will be released if a break occurs in the line. 
For additional information see section A-2, Secondary Containment. EPA 
is not requiring secondary containment for piping associated with 
field-constructed tanks greater than 50,000 gallons in capacity and 
airport hydrant system piping due to sloping and corrosion concerns. 
For additional information, see section C-2, Airport Hydrant Fuel 
Distribution Systems and UST Systems with Field-Constructed Tanks.
    In Sec.  281.30(b), EPA is requiring states, which receive SPA, not 
allow installation of flow restrictors (commonly referred to as ball 
floats) in vent lines for overfill prevention for new installations or 
when flow restrictors need to be replaced. The existing goal of Sec.  
281.30(b) is for states to require that UST systems have equipment to 
prevent spills and overfills. In this final UST regulation, EPA 
maintains the overall goal to prevent spills and overfills; however, 
owners and operators can no longer install ball floats to achieve that 
goal.
    The deadlines for upgrades and for owners and operators to obtain 
financial responsibility have passed. As a result, EPA is deleting the 
1988 UST regulation deadlines in the final SPA regulation. In 
Sec. Sec.  281.31 and 281.33(b), EPA is removing the option for UST 
upgrades, except for USTs deferred in the 1988 UST regulation. In Sec.  
281.37, we are eliminating the financial responsibility phase-in 
schedule. Please note EPA is allowing states to implement UST 
requirements, such as upgrades and operation and maintenance, after the 
deadlines in 40 CFR part 280. EPA is taking this action because 
experience has shown that some states had difficulties implementing a 
retroactive requirement when applying for SPA after a federal deadline 
has passed.
    In Sec.  281.33(c), EPA is allowing monthly inventory control in 
combination with tank tightness testing conducted every five years as a 
release detection method for the first ten years after a tank is 
installed or upgraded, only if a tank was installed prior to a state 
receiving SPA for the 1988 UST regulation. This reflects a change in 40 
CFR part 280 and avoids another problem in the 1988 SPA regulation. 
First, EPA is eliminating this method for new installations. Second, 
EPA is tying the date for eliminating this method to the effective date 
of a state's regulations. EPA concludes it is better to tie deadlines 
in the final SPA regulation to the effective date of states' 
regulations, rather than dictate specific dates for all states. In the 
2011 proposed SPA regulation, we tied the deadlines to the date a state 
submitted its SPA application or revised application. However, in this 
final SPA regulation, we realize tying the deadlines to the effective 
date of a state's regulations is clearer for state regulators as well 
as owners and operators.
    Several commenters were concerned with how release detection 
requirements were expressed in 40 CFR part 281. One commenter was 
concerned that the term monthly in Sec.  281.33(c)(1) is not as 
stringent as the 40 CFR part 280 requirement of completing release 
detection every 30 days. This commenter wanted EPA to amend the 40 CFR 
part 281 language so it matches the 30 day wording in 40 CFR part 280. 
EPA is maintaining the term monthly in 40 CFR part 281. EPA agrees 
there is variation between the 30 day time frame in 40 CFR part 280 and 
monthly in 40 CFR part 281. For states receiving SPA, the difference 
should result in a variation of only a few days, and therefore need not 
be changed. It is EPA's position that release detection monitoring 
should be conducted on a consistent and frequently occurring basis. EPA 
chose the 30 day period in 40 CFR part 280 to represent an average 
calendar month.

[[Page 41619]]

    In this final SPA regulation, EPA is requiring states, which wish 
to receive SPA, no longer allow installation of non-secondarily 
contained hazardous substance UST systems. This is consistent with 
EPA's change in Sec.  280.42(e); an equivalent and specific change in 
the final SPA regulation is the only way to ensure states adopt it. For 
consistency with changes in this final UST regulation and to ensure 
states wishing to receive SPA adopt this change, in Sec.  281.34(a)(1), 
EPA is adding ``. . . interstitial space may have been compromised . . 
.'' to suspected release conditions.
    One commenter expressed concern with the release detection language 
in Sec.  280.41(b)(2)(ii), which indicates EPA intends to exempt from 
release detection requirements suction piping that meets the condition 
of paragraphs (b)(1)(ii)(A) through (E). However Sec.  281.33(d)(3) 
indicates that in order to be considered no less stringent, states must 
require new or replaced piping use interstitial monitoring with 
secondary containment. EPA agrees with the commenter that we need to 
modify Sec.  281.33(d)(3) to incorporate the concepts of Sec.  
280.41(b)(2)(ii). In the final SPA regulation, EPA is modifying Sec.  
281.33(d)(3) to indicate that the requirement is applicable to all 
pressurized piping and suction piping that does not meet standards in 
Sec.  281.33(d)(2)(ii).
    One commenter said that it may be very difficult to achieve 
compliance with release detection requirements for emergency power 
generator USTs within one year. This commenter suggested that EPA 
reword Sec.  281.33(b)(3) to give owners at least three years from the 
effective date of the final SPA regulation. EPA agrees with the 
commenter and is extending the date of compliance for this requirement 
to three years as we are in this final UST regulation; this approach 
corresponds with EPA's goal of aligning dates of compliance to the 
extent possible.

Addressing SPA Revision Process

    EPA is adding a requirement for approved states to submit a revised 
application within three years of final SPA regulation changes that 
require a program revision under Sec.  281.51. Approved states are 
required to revise their programs and submit revised applications 
whenever the federal program changes or EPA's Administrator requests a 
revised application based on changes to a state's program. Given these 
significant changes, EPA thinks it is necessary to develop a time frame 
which will ensure approved states meet final SPA regulation changes in 
a reasonable time. EPA's language in Sec.  281.51 is intended only to 
require a state program revision within three years if EPA makes 
changes that necessitate state program changes. For instance, these 
changes to subpart C--Criteria for No Less Stringent will require state 
program revision.
    Commenters disagreed on the appropriate time frame for states to 
submit their SPA applications. Some said three years was appropriate, 
while others preferred a different time frame. EPA maintains that three 
years is adequate for most states to re-apply for SPA. One commenter 
expressed concern about what will happen to a state's SPA status if it 
does not re-apply within the required time frame. While most states 
will be able to meet the three-year deadline for program revision, EPA 
is aware that some states may need additional time. EPA will work with 
states which have not revised their programs within three years. EPA 
will ask those states to demonstrate their level of effort, show 
progress to date, and provide dates when they will achieve major 
milestones for revising their programs and submitting revised 
applications. EPA will consider these factors before initiating state 
program approval withdrawal. One commenter was concerned about the cost 
to states of revising and reapplying for SPA. It is important for 
states to reapply for SPA to ensure they make appropriate changes to 
their programs.

Additional Changes to SPA Regulation

    EPA is making these additional changes; they are not a direct 
result of these 40 CFR part 280 changes. Rather, the majority are 
corrections to the 1988 SPA regulation.

 Sec.  281.10--change subpart to part
 Sec. Sec.  281.11(c), 281.20(d), 281.21(a)(2), 281.23, and 
formerly Sec.  281.51--eliminate interim approval
 Sec.  281.12(a)(2)--change Indian lands to Indian country
 Sec.  281.32(e)--eliminate requirement to maintain upgrade 
records
 Formerly Sec.  281.38--eliminate reserved section for 
financial responsibility for USTs containing hazardous substances
 Move Sec.  281.39 to Sec.  281.38--Lender Liability
 Sec. Sec.  281.50(e) and 281.51(c)(1)--clarify how to provide 
public notice to attract statewide attention
 Sec.  281.61--move Sec.  281.60(b) to Sec.  281.61(b)(2)

    The 1988 SPA regulation incorrectly uses the term subpart in Sec.  
280.10 and, therefore, EPA is correctly changing this to part. EPA has 
been using the term Indian country instead of Indian lands for years. 
We are now incorporating this term in this final SPA regulation; this 
does not alter the meaning. EPA is removing the reserved financial 
responsibility for USTs containing hazardous substances section 
(formerly Sec.  281.38); moving the lender liability section from Sec.  
281.39 to Sec.  281.38; and including the new operator training section 
in Sec.  281.39. Because operator training needs to be in subpart C, 
which has no section numbers available, this eliminates the need to 
renumber subpart D. Also, the reserved financial responsibility for 
hazardous substances section is unnecessary since there is no 
corresponding requirement in 40 CFR part 280.
    EPA is deleting the interim SPA approval language in Sec. Sec.  
281.11(c) and 281.51. In more than 20 years of the UST program, no 
state applied for interim approval; it is more beneficial to receive 
full approval all at once, rather than in steps. Also, because 40 
states, including the District of Columbia and Puerto Rico, have SPA as 
of 2014, EPA thinks interim SPA approval is unnecessary at this time.
    EPA is eliminating the requirement to maintain upgrade records for 
the operational life of an UST facility. This requirement in Sec.  
281.32(e) of the 1988 SPA regulation does not exist in 40 CFR part 280. 
In addition, except for airport hydrant systems and field-constructed 
tanks, EPA is no longer allowing upgrades.
    EPA is clarifying how to provide public notice to attract statewide 
attention in Sec. Sec.  281.50(e) and 281.51(c)(1). In today's digital 
age, it is unnecessary to require publication in a state's newspapers. 
Each state can determine the most appropriate methods for public notice 
and statewide attention.
    EPA is also moving Sec.  281.60(b) to Sec.  281.61(b). This 
paragraph explains the procedure EPA will follow to withdraw approval 
after the conclusion of the proceeding to withdraw approval. EPA thinks 
this paragraph is better suited for Sec.  281.61, which explains the 
procedures for withdrawing approval, as opposed to Sec.  281.60, which 
explains the criteria for withdrawal.

VI. Overview of Estimated Costs and Benefits

    EPA prepared an analysis of the potential incremental costs and 
benefits associated with this final UST regulation. This analysis is 
contained in the regulatory impact analysis document titled Assessment 
of the Potential Costs, Benefits, and Other Impacts of the Final 
Revisions to EPA's

[[Page 41620]]

Underground Storage Tank Regulations, which is available in the docket 
for this action. The RIA estimated regulatory implementation and 
compliance costs, as well as benefits for the three regulatory options 
described in section IV, subsection F. In the RIA, EPA estimated 
regulatory compliance costs on an annualized basis for the three 
options: $160 million (Selected Option), $290 million (Option 1), and 
$70 million (Option 2). Separately, the analysis assessed the potential 
benefits of the final UST regulation. As discussed in the RIA, a 
substantial portion of the beneficial impacts associated with the final 
UST regulation are avoided cleanup costs as a result of preventing 
releases and reducing the severity of releases. This action is expected 
to have annual cost savings related to avoided costs of $310 million 
(range: $120-$530 million) per year under the Selected Option, $450 
million (range: $210-$670 million) per year under Option 1, and $230 
million (range: $45-$420 million) per year under Option 2. Due to data 
and resource constraints, EPA was unable to quantify some of the final 
UST regulation's benefits, including avoidance of human health risks, 
ecological benefits, and mitigation of acute exposure events and large-
scale releases, such as those from airport hydrant systems and field-
constructed tanks. EPA was also unable to place a monetary value on the 
groundwater protected by the final UST regulation, but estimates that 
this final UST regulation could potentially protect 50 billion to 240 
billion gallons of groundwater each year.

VII. Statutory and Executive Orders

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulation and Regulatory Review

    Under section 3(f)(1) of Executive Order (EO) 12866 (58 FR 51735, 
October 4, 1993), this action is an economically significant regulatory 
action because it is likely to have an annual effect on the economy of 
$100 million or more. Accordingly, EPA submitted this action to the 
Office of Management and Budget (OMB) for review under EO 12866 and EO 
13563 (76 FR 3821, January 21, 2011) and any changes made in response 
to OMB recommendations are documented in the docket for this action. 
Also, as part of EO 13563, EPA encourages owners and operators to 
maintain records electronically which simplifies compliance and 
recordkeeping by using 21st century technology tools.\121\

Review, Section 3, https://www.gpo.gov/fdsys/pkg/FR-2011-01-21/pdf/2011-1385.pdf.
---------------------------------------------------------------------------

B. Paperwork Reduction Act

    The information collection requirements (ICR) in this rule will be 
submitted for approval to the Office of Management and Budget (OMB) 
under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. The 
information collection requirements are not enforceable until OMB 
approves them.
    The proposed rule ICR was submitted to OMB on 11/18/2011 under OMB 
number 2050-0068, ICR number 1360.11. On 1/30/2012 OMB released a 
Notice of Action of comment filed on proposed rule and continue. They 
also issued this comment: ``Terms of the previous clearance remain in 
effect. OMB is withholding approval at this time. Prior to publication 
of the final rule, the agency should provide a summary of any comments 
related to the information collection and their response, including any 
changes made to the ICR as a result of comments. In addition, the 
agency must enter the correct burden estimates. This action has no 
effect on any current approvals.'' The final rule ICR will be submitted 
to OMB under a new ICR OMB control number.
    This action contains mandatory information collection requirements. 
The labor burden and associated costs for these requirements are 
estimated in the ICR supporting statement for this final action. The 
supporting statement identifies and estimates the burden for each of 
the changes to the regulation that include recordkeeping or reporting 
requirements. Changes include: adding secondary containment 
requirements for new and replaced tanks and piping; adding operator 
training requirements; adding periodic operation and maintenance 
requirements for UST systems; regulating certain UST systems deferred 
in the 1988 UST regulation; adding new release prevention and detection 
technologies; and updating state program approval requirements to 
incorporate these new changes.
    Based on the same data and cost calculations applied in the RIA for 
this action, but using the burden estimations for ICRs, the ICR 
supporting statement estimates an average annual labor hour burden of 
344,000 hours and $12 million for the final UST regulation. One time 
capital and hourly costs are included in these estimates based on a 
three year annualization period. Burden is defined at 5 CFR 1320.3(b). 
The total universe of respondents for this ICR is comprised of 211,154 
facilities and 56 states and territories. Burden is defined at 5 CFR 
1320.3(b).
    An agency may not conduct or sponsor, and a person is not required 
to respond to, a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for EPA's 
regulations are listed in 40 CFR part 9. When this ICR is approved by 
OMB, the agency will publish a technical amendment to 40 CFR part 9 in 
the Federal Register to display the OMB control number for the approved 
information collection requirements contained in this final rule.

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act generally requires an agency to 
prepare a regulatory flexibility analysis of any regulation subject to 
notice and comment rulemaking requirements under the Administrative 
Procedure Act or any other statute, unless the agency certifies that 
the regulation will not have a significant economic impact on a 
substantial number of small entities. Small entities include small 
businesses, small organizations, and small governmental jurisdictions.
    For purposes of assessing the impacts of this final UST regulation 
on small entities, a small entity is defined as: (1) A small business 
as defined by the Small Business Administration's regulations at 13 CFR 
121.201; (2) a small governmental jurisdiction that is a government of 
a city, county, town, school district, or special district with a 
population of less than 50,000; and (3) a small organization that is 
any not-for-profit enterprise which is independently owned and operated 
and is not dominant in its field.
    After considering the economic impacts of this final rule on small 
entities, I certify that this action will not have a significant 
economic impact on a substantial number of small entities. The small 
entities directly regulated by this final rule are small businesses and 
small governmental jurisdictions. We have determined that less than 1 
percent of potentially affected small firms in the retail motor fuel 
sector (NAICS 447) will experience an impact over 1 percent of 
revenues, but less than 3 percent of revenues. No small firms have 
impacts above 3 percent of revenues. In addition, we estimate that no 
small governmental jurisdictions will be impacted at 1 percent or 3 
percent of revenues. This certification is based on the small entities 
analysis contained in the RIA for this final rule.

[[Page 41621]]

    Although this final rule will not have a significant economic 
impact on a substantial number of small entities, EPA nonetheless 
sought to reduce the impact of this rule on small entities. EPA 
conducted extensive outreach to determine how to change the 1988 UST 
regulation. EPA worked with representatives of owners and operators and 
reached out specifically to small businesses. In addition, EPA limited 
changes that would have required major retrofits to UST systems, since 
this would place a high financial burden on small businesses. Finally, 
EPA provided numerous options for compliance in order to provide as 
much flexibility as possible for small entities. EPA also aligned 
compliance dates to facilitate owner and operator compliance.

D. Unfunded Mandates Reform Act

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 
U.S.C. 1531-1538, requires federal agencies, unless otherwise 
prohibited by law, to assess the effects of their regulatory actions on 
state, local, and tribal governments and the private sector. This rule 
contains a federal mandate that may result in expenditures of $100 
million or more for state, local, and tribal governments, in the 
aggregate, or the private sector in any one year. Accordingly, EPA 
prepared under section 202 of the UMRA a written statement which is 
summarized below.
    As estimated in the RIA, on an annualized basis, the total 
estimated regulatory compliance costs for the three options in this 
final action are $160 million (Selected Option), $290 million (Option 
1), and $70 million (Option 2). Of this amount, annualized costs to 
state and local governments total $6.8 million under the Selected 
Option, $14 million under Option 1, and $3.6 million under Option 2. 
These costs consist of estimated regulatory compliance costs for state 
and local governments that currently own or operate UST systems and 
annualized costs of $120,000 for states to implement the final UST 
regulation. EPA estimates total annualized costs to owners and 
operators of tribally-owned UST systems are $0.67 million under the 
Selected Option. The estimated annualized cost to the private sector is 
approximately $130 million under the Selected Option, $270 million 
under Option 1, and $67 million under Option 2. While this final UST 
regulation may result in expenditures of $100 million or more for the 
private sector, thereby triggering section 202 of the UMRA, this final 
UST regulation is not subject to the requirements of section 204 of 
UMRA because EPA does not think state, local, and tribal governments 
will incur aggregate costs of over $100 million per year.
    Consistent with section 205, EPA identified and considered a 
reasonable number of regulatory alternatives. This final UST regulation 
identifies the regulatory options EPA considered. The RIA estimates the 
annual cost across the three considered options may range between $70 
million and $290 million. Section 205 of the UMRA requires federal 
agencies to select the least costly or most cost-effective regulatory 
alternative unless EPA publishes with the final regulation an 
explanation of why such alternative was not adopted. As discussed 
earlier in the preamble, EPA considered and evaluated variations of a 
subset of the regulatory requirements using two alternative options 
(Options 1 and 2). Despite Option 2's lower costs, EPA chose the 
Selected Option because it provides for greater protection of human 
health and the environment and better addresses stakeholder concerns.
    This rule is not subject to the requirements of section 203 of UMRA 
because it contains no regulatory requirements that might significantly 
or uniquely affect small governments.

E. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have 
substantial direct effects on states, the relationship between the 
federal government and states, or the distribution of power and 
responsibilities among various levels of government, as specified in EO 
13132. Under this final action, total costs to all affected states and 
local governments (including direct compliance costs, notification 
costs, and state program costs) are approximately $9 million. This is 
not considered to be a substantial compliance cost under federalism 
requirements. Thus, Executive Order 13132 does not apply to this 
action.
    In the spirit of Executive Order 13132, and consistent with EPA 
policy to promote communications between EPA and State and local 
governments, EPA specifically solicited comment on the proposed action 
from State and local officials.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    Subject to Executive Order 13175 (65 FR 67249, November 9, 2000) 
EPA may not issue a regulation that has tribal implications, that 
imposes substantial direct compliance costs, and that is not required 
by statute, unless the Federal government provides the money necessary 
to pay the direct compliance costs incurred by tribal governments, or 
EPA consults with tribal officials early in the process of developing 
the proposed regulation and develops a tribal summary impact statement.
    EPA has concluded that this action will have tribal implications to 
the extent that tribally-owned entities with UST systems in Indian 
country will be affected. However, it will neither impose substantial 
direct compliance costs on tribal governments, nor preempt tribal law. 
EPA estimated total annualized costs for tribally-owned UST systems in 
Indian country to be $0.67 million.
    EPA consulted with tribal officials early in the process of 
developing this regulation to permit them to have meaningful and timely 
input to its development. EPA consulted with tribes on possible changes 
to the UST regulation shortly after the passage of the Energy Policy 
Act of 2005. The Energy Policy Act directed EPA to coordinate with 
tribes in developing and implementing an UST program strategy in Indian 
country which would supplement the existing approach. EPA and tribes 
worked collaboratively to develop a tribal strategy.
    There are certain key provisions of the Energy Policy Act that 
apply to states receiving federal Subtitle I money, but do not apply in 
Indian country. Nonetheless, EPA's goal in this final UST regulation is 
to establish in Indian country federal requirements similar to the 
Energy Policy Act provisions; this is an important step in achieving 
more consistent program results in release prevention. Both EPA and 
tribes recognize the importance of ensuring parity in program 
implementation between states and in Indian country.
    In addition to early consultation with tribes, EPA also reached out 
to tribes as we started the official rulemaking process and while 
developing the 2011 proposed UST regulation. EPA sent letters to 
leaders of over 500 tribes, as well as to tribal regulatory staff, 
inviting their participation in developing the 2011 proposed UST 
regulation. EPA also held conference calls for tribes to provide input. 
EPA heard from both tribal officials who work as regulators as well as 
representatives of owners and operators of UST systems in Indian 
country. The tribal regulators raised concerns about ensuring parity of 
environmental protection between states and Indian country.
    EPA determined that this final UST regulation is needed to ensure 
parity between UST systems in states and in Indian country. This final 
UST regulation is also needed to ensure

[[Page 41622]]

equipment is both installed and working properly, which will protect 
the environment from potential releases.
    As required by section 7(a), EPA's Tribal Consultation Official 
certified that the requirements of the Executive Order have been met in 
a meaningful and timely manner. EPA included a copy of the 
certification in the docket for this action.

G. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    This action is not subject to EO 13045 (62 FR 19885, April 23, 
1997) because the Agency does not think the environmental health risks 
or safety risks addressed by this action present a disproportionate 
risk to children. EPA's risk assessment for this action examines 
potential impacts to groundwater and subsequent chemical transport, 
exposure, and risk. While the risk assessment did not specifically 
measure exposure to children, the general exposure scenarios reflect 
four exposure pathways that have the most significant potential for 
human health impacts. They are:
     Ingestion of chemicals in groundwater that have migrated 
from the source area to residential drinking water wells;
     Inhalation of volatile chemicals when showering with 
contaminated groundwater;
     Dermal contact with chemicals while bathing or showering 
with contaminated groundwater; and
     Inhalation of vapors that may migrate upward from 
contaminated groundwater into overlying buildings.
    Adults and children can potentially be exposed through all four 
exposure pathways considered. For adults, inhalation of vapors while 
showering is the most significant exposure pathway; for children, 
ingestion is the most significant pathway, because they are assumed to 
take baths and are, therefore, not exposed via shower vapor inhalation. 
As a result of the longer exposure from showering, adults are more 
sensitive receptors for cancer effects compared to children, 
particularly those under age 5 who are assumed to take more baths and 
fewer showers.\122\

Registry, Toxicological Profile For Polycyclic Aromatic 
Hydrocarbons, August 1995.
---------------------------------------------------------------------------

    While the screening level risk assessment is limited in that it 
only examines benzene impacts, the final UST regulation will likely 
reduce other contaminant exposures to children in a similar pattern and 
will not create significant adverse impacts on children's health.
    The screening level population analysis performed to examine EO 
12898 shows that children under 18 years and children under 5 years of 
age are slightly less likely to be found in the vicinity of UST 
facilities. This suggests that the impacts of this action will not have 
a disproportionate impact on children's health. Moreover, because all 
regulatory options in this action will increase regulatory stringency 
and reduce the number and size of releases, EPA does not expect this 
action to have any disproportionate adverse impact on children.

H. Executive Order 13211: Actions Concerning Regulations that 
Significantly Affect Energy Supply, Distribution, or Use

    This action is not a significant energy action as defined in 
Executive Order 13211 (66 FR 28355, May 22, 2001), because it is not 
likely to have a significant adverse effect on the supply, 
distribution, or use of energy. The following summarizes EPA's 
assessment of the energy impacts this final UST regulation will have on 
energy supply, distribution, and use.
    This final UST regulation consists of additional regulatory 
requirements that apply to the owners and operators of underground 
storage tanks. To the extent that the final UST regulation affects the 
motor fuel sector, it does so at the retail motor fuel sales level, 
rather than the level of refineries or distributors, who supply the 
retail stations with motor fuel. Therefore, we do not expect this final 
UST regulation to have a significant adverse impact on energy supply or 
distribution.
    The additional regulatory requirements contained in this final UST 
regulation may increase compliance costs for owners and operators of 
retail motor fuel stations. If owners and operators of retail motor 
fuel stations affected by the final UST regulation can pass through 
their increased compliance costs, energy use may be affected via higher 
energy prices caused by the final UST regulation. However, we do not 
expect a significant change in retail gasoline prices to result from 
this final UST regulation for the following reasons:
     Economic analyses of retail fuel prices revealed that 
demand for gasoline is highly sensitive to price (elastic) within 
localized geographic areas--as a result, if one motor fuel retailer in 
an area passes through increases in compliance costs by increasing 
gasoline prices, while another does not, the one with higher prices is 
at a competitive disadvantage; and
     Retail motor fuel stations often have associated stores or 
services, such as car washes, repair operations, and convenience 
outlets, on which they can more successfully pass through increases in 
compliance costs.
    Furthermore, when considered in the context of total fuel 
consumption in the United States, this final UST regulation will 
represent only a very small fraction of motor fuel prices, even if 
fully passed through to consumers. According to the Bureau of 
Transportation Statistics, the United States consumed approximately 169 
billion gallons of motor fuel (including gasoline and diesel) in 2011 
at an average price of $3.73.\123\ This implies that consumers spent 
$629 billion in 2012 on motor fuel. The overall cost of the final UST 
regulation is approximately $160 million, less than 0.1 percent of the 
amount spent by end users on motor fuel in 2012. In comparison, an 
increase of 1 cent in the average price of motor fuel in 2012 would 
have increased the total cost to consumers by approximately $1.7 
billion. Given these circumstances, this final UST regulation should 
not measurably impact retail motor fuel prices. As a result, EPA does 
not expect this final UST regulation to have a significant adverse 
impact on energy prices or use.
---------------------------------------------------------------------------

    \123\ 2011 is the latest year data available from Bureau of 
Transportation Statistics for gallons of motor fuel consumed, as 
reported by: U.S. Department of Transportation, Research and 
Innovative Technology Administration, Bureau of Transportation 
Statistics. Accessed at: https://www.rita.dot.gov/bts/sites/rita.dot.gov.bts/files/publications/national_transportation_statistics/html/table_04_09.html. The 2012 
prices per gallon for all grades of retail motor gasoline and No. 2 
diesel fuel (all concentrations of sulfur) were $3.63 and $3.97, 
respectively, as reported by: U.S. Energy Information 
Administration. Short-Term Energy Outlook--Real and Nominal Energy 
Prices for 2012. Accessed at: https://www.eia.gov/forecasts/steo/realprices/. We weight these prices according to prime supplier 
sales volumes in 2012 published by the Energy Information 
Administration, which summed to 347,234.5 thousands of gallons per 
day for gasoline and 143,270.6 thousands of gallons per day for all 
grades of diesel fuel (U.S. Energy Information Administration.

I. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (NTTAA), Public Law 104-113 (15 U.S.C. 272 note) directs 
EPA to use voluntary consensus standards in its regulatory activities 
unless to do so would be inconsistent with applicable law or otherwise 
impractical. Voluntary consensus standards are technical

[[Page 41623]]

standards (e.g., materials specifications, test methods, sampling 
procedures, and business practices) that are developed or adopted by 
voluntary consensus standards bodies. NTTAA directs EPA to provide 
Congress, through OMB, explanations when EPA decides not to use 
available and applicable voluntary consensus standards.
    This action uses technical standards. EPA has decided to use 
voluntary consensus standards, called codes of practice, described in 
section E-2. These codes of practice meet the objectives of this action 
by establishing criteria for the design, construction, and maintenance 
of underground storage tanks.

J. Executive Order 12898: Federal Actions to Address Environmental 
Justice in Minority Populations and Low-Income Populations

    Executive Order 12898 (59 FR 7629, Feb. 16, 1994) establishes 
federal executive policy on environmental justice. Its main provision 
directs federal agencies, to the greatest extent practicable and 
permitted by law, to make environmental justice part of their mission 
by identifying and addressing, as appropriate, disproportionately high 
and adverse human health or environmental effects of their programs, 
policies, and activities on minority populations and low-income 
populations in the United States.
    EPA has determined that this action will not have 
disproportionately high and adverse human health or environmental 
effects on minority or low-income populations because it increases the 
level of environmental protection for all affected populations without 
having any disproportionately high and adverse human health or 
environmental effects on any population, including any minority or low-
income population.
    To inform us about the socioeconomic characteristics of communities 
potentially affected by this final UST regulation, EPA conducted a 
screening analysis under the 2011 proposed UST regulation to examine 
whether there is a statistically significant disparity between 
socioeconomic characteristics of populations located near UST 
facilities and those that are not.\124\ As discussed in the RIA, the 
results indicate that minority and low-income populations are slightly 
more likely to be located near UST facilities. An environmental justice 
analysis would then require an assessment of whether there would be 
disproportionate and adverse impacts on these populations. However, 
because all regulatory options considered in this final UST regulation 
would increase regulatory stringency and reduce the number and size of 
releases, EPA does not anticipate the final UST regulation will have 
any disproportionately high and adverse human health or environmental 
effects on these minority or low-income communities or any community.
---------------------------------------------------------------------------

    \124\ Note that the affected populations identified in the 
screening analysis summarized here are simply defined by specific 
demographics surrounding UST locations. These affected populations 
are not necessarily equivalent to communities that others have 
specifically identified as environmental justice communities.
---------------------------------------------------------------------------

K. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this rule and other 
required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A Major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is a ``major rule'' as defined by 5 U.S.C. 
804(2). This rule is effective September 14, 2015.

Sec.  280.11  Installation requirements for partially excluded UST 
systems.

    (a) Owners and operators must install an UST system listed in Sec.  
280.10(c)(1), (3), or (4) storing regulated substances (whether of 
single or double wall construction) that meets the following 
requirements:
    (1) Will prevent releases due to corrosion or structural failure 
for the operational life of the UST system;
    (2) Is cathodically protected against corrosion, constructed of 
non-corrodible material, steel clad with a non-corrodible material, or 
designed in a manner to prevent the release or threatened release of 
any stored substance; and
    (3) Is constructed or lined with material that is compatible with 
the stored substance.
    (b) Notwithstanding paragraph (a) of this section, an UST system 
without corrosion protection may be installed at a site that is 
determined by a corrosion expert not to be corrosive enough to cause it 
to have a release due to corrosion during its operating life. Owners 
and operators must maintain records that demonstrate compliance with 
the requirements of this paragraph for the remaining life of the tank.

    Note to paragraphs (a) and (b).  The following codes of practice 
may be used as guidance for complying with this section:
    (A) NACE International Standard Practice SP 0285, ``External 
Corrosion Control of

[[Page 41625]]

Underground Storage Tank Systems by Cathodic Protection'';
    (B) NACE International Standard Practice SP 0169, ``Control of 
External Corrosion on Underground or Submerged Metallic Piping 
Systems'';
    (C) American Petroleum Institute Recommended Practice 1632, 
``Cathodic Protection of Underground Petroleum Storage Tanks and 
Piping Systems''; or
    (D) Steel Tank Institute Recommended Practice R892, 
``Recommended Practice for Corrosion Protection of Underground 
Piping Networks Associated with Liquid Storage and Dispensing 
Systems''.

Sec.  280.12  Definitions.

    Aboveground release means any release to the surface of the land or 
to surface water. This includes, but is not limited to, releases from 
the aboveground portion of an UST system and aboveground releases 
associated with overfills and transfer operations as the regulated 
substance moves to or from an UST system.
    Ancillary equipment means any devices including, but not limited 
to, such devices as piping, fittings, flanges, valves, and pumps used 
to distribute, meter, or control the flow of regulated substances to 
and from an UST.
    Belowground release means any release to the subsurface of the land 
and to groundwater. This includes, but is not limited to, releases from 
the belowground portions of an underground storage tank system and 
belowground releases associated with overfills and transfer operations 
as the regulated substance moves to or from an underground storage 
tank.
    Beneath the surface of the ground means beneath the ground surface 
or otherwise covered with earthen materials.
    Cathodic protection is a technique to prevent corrosion of a metal 
surface by making that surface the cathode of an electrochemical cell. 
For example, a tank system can be cathodically protected through the 
application of either galvanic anodes or impressed current.

operation of the new UST system.


Sec.  280.43  Methods of release detection for tanks.

    Each method of release detection for tanks used to meet the 
requirements of Sec.  280.41 must be conducted in accordance with the 
following:
    (a) Inventory control. Product inventory control (or another test 
of equivalent performance) must be conducted monthly to detect a 
release of at least 1.0 percent of flow-through plus 130 gallons on a 
monthly basis in the following manner:
    (1) Inventory volume measurements for regulated substance inputs, 
withdrawals, and the amount still remaining in the tank are recorded 
each operating day;
    (2) The equipment used is capable of measuring the level of product 
over the full range of the tank's height to the nearest one-eighth of 
an inch;
    (3) The regulated substance inputs are reconciled with delivery 
receipts by measurement of the tank inventory volume before and after 
delivery;
    (4) Deliveries are made through a drop tube that extends to within 
one foot of the tank bottom;
    (5) Product dispensing is metered and recorded within the local 
standards for meter calibration or an accuracy of 6 cubic inches for 
every 5 gallons of product withdrawn; and
    (6) The measurement of any water level in the bottom of the tank is 
made to the nearest one-eighth of an inch at least once a month.

    Note to paragraph (a). Practices described in the American 
Petroleum Institute Recommended Practice RP 1621, ``Bulk Liquid 
Stock Control at Retail Outlets'' may be used, where applicable, as 
guidance in meeting the requirements of this paragraph (a).

    (b) Manual tank gauging. Manual tank gauging must meet the 
following requirements:
    (1) Tank liquid level measurements are taken at the beginning and 
ending of a period using the appropriate minimum duration of test value 
in the table below during which no liquid is added to or removed from 
the tank;
    (2) Level measurements are based on an average of two consecutive 
stick readings at both the beginning and ending of the period;
    (3) The equipment used is capable of measuring the level of product 
over the full range of the tank's height to the nearest one-eighth of 
an inch;
    (4) A release is suspected and subject to the requirements of 
subpart E if the variation between beginning and ending measurements 
exceeds the weekly or monthly standards in the following table:

----------------------------------------------------------------------------------------------------------------
                                                                  Weekly standard (one    Monthly standard (four
        Nominal tank capacity         Minimum duration of test           test)                test average)
----------------------------------------------------------------------------------------------------------------
550 gallons or less.................  36 hours................  10 gallons.............  5 gallons
551-1,000 gallons (when tank          44 hours................  9 gallons..............  4 gallons
 diameter is 64 inches).
551-1,000 gallons (when tank          58 hours................  12 gallons.............  6 gallons
 diameter is 48 inches).
551-1,000 gallons (also requires      36 hours................  13 gallons.............  7 gallons
 periodic tank tightness testing).
1,001-2,000 gallons (also requires    36 hours................  26 gallons.............  13 gallons
 periodic tank tightness testing).
----------------------------------------------------------------------------------------------------------------


[[Page 41635]]

    (5) Tanks of 550 gallons or less nominal capacity and tanks with a 
nominal capacity of 551 to 1,000 gallons that meet the tank diameter 
criteria in the table in paragraph (b)(4) of this section may use this 
as the sole method of release detection. All other tanks with a nominal 
capacity of 551 to 2,000 gallons may use the method in place of 
inventory control in Sec.  280.43(a). Tanks of greater than 2,000 
gallons nominal capacity may not use this method to meet the 
requirements of this subpart.
    (c) Tank tightness testing. Tank tightness testing (or another test 
of equivalent performance) must be capable of detecting a 0.1 gallon 
per hour leak rate from any portion of the tank that routinely contains 
product while accounting for the effects of thermal expansion or 
contraction of the product, vapor pockets, tank deformation, 
evaporation or condensation, and the location of the water table.
    (d) Automatic tank gauging. Equipment for automatic tank gauging 
that tests for the loss of product and conducts inventory control must 
meet the following requirements:
    (1) The automatic product level monitor test can detect a 0.2 
gallon per hour leak rate from any portion of the tank that routinely 
contains product;
    (2) The automatic tank gauging equipment must meet the inventory 
control (or other test of equivalent performance) requirements of Sec.  
280.43(a); and
    (3) The test must be performed with the system operating in one of 
the following modes:
    (i) In-tank static testing conducted at least once every 30 days; 
or
    (ii) Continuous in-tank leak detection operating on an 
uninterrupted basis or operating within a process that allows the 
system to gather incremental measurements to determine the leak status 
of the tank at least once every 30 days.
    (e) Vapor monitoring. Testing or monitoring for vapors within the 
soil gas of the excavation zone must meet the following requirements:
    (1) The materials used as backfill are sufficiently porous (e.g., 
gravel, sand, crushed rock) to readily allow diffusion of vapors from 
releases into the excavation area;
    (2) The stored regulated substance, or a tracer compound placed in 
the tank system, is sufficiently volatile (e.g., gasoline) to result in 
a vapor level that is detectable by the monitoring devices located in 
the excavation zone in the event of a release from the tank;
    (3) The measurement of vapors by the monitoring device is not 
rendered inoperative by the groundwater, rainfall, or soil moisture or 
other known interferences so that a release could go undetected for 
more than 30 days;
    (4) The level of background contamination in the excavation zone 
will not interfere with the method used to detect releases from the 
tank;
    (5) The vapor monitors are designed and operated to detect any 
significant increase in concentration above background of the regulated 
substance stored in the tank system, a component or components of that 
substance, or a tracer compound placed in the tank system;
    (6) In the UST excavation zone, the site is assessed to ensure 
compliance with the requirements in paragraphs (e)(1) through (4) of 
this section and to establish the number and positioning of monitoring 
wells that will detect releases within the excavation zone from any 
portion of the tank that routinely contains product; and
    (7) Monitoring wells are clearly marked and secured to avoid 
unauthorized access and tampering.
    (f) Groundwater monitoring. Testing or monitoring for liquids on 
the groundwater must meet the following requirements:
    (1) The regulated substance stored is immiscible in water and has a 
specific gravity of less than one;
    (2) Groundwater is never more than 20 feet from the ground surface 
and the hydraulic conductivity of the soil(s) between the UST system 
and the monitoring wells or devices is not less than 0.01 cm/sec (e.g., 
the soil should consist of gravels, coarse to medium sands, coarse 
silts or other permeable materials);
    (3) The slotted portion of the monitoring well casing must be 
designed to prevent migration of natural soils or filter pack into the 
well and to allow entry of regulated substance on the water table into 
the well under both high and low groundwater conditions;
    (4) Monitoring wells shall be sealed from the ground surface to the 
top of the filter pack;
    (5) Monitoring wells or devices intercept the excavation zone or 
are as close to it as is technically feasible;
    (6) The continuous monitoring devices or manual methods used can 
detect the presence of at least one-eighth of an inch of free product 
on top of the groundwater in the monitoring wells;
    (7) Within and immediately below the UST system excavation zone, 
the site is assessed to ensure compliance with the requirements in 
paragraphs (f)(1) through (5) of this section and to establish the 
number and positioning of monitoring wells or devices that will detect 
releases from any portion of the tank that routinely contains product; 
and
    (8) Monitoring wells are clearly marked and secured to avoid 
unauthorized access and tampering.
    (g) Interstitial monitoring. Interstitial monitoring between the 
UST system and a secondary barrier immediately around or beneath it may 
be used, but only if the system is designed, constructed, and installed 
to detect a leak from any portion of the tank that routinely contains 
product and also meets one of the following requirements:
    (1) For double walled UST systems, the sampling or testing method 
can detect a leak through the inner wall in any portion of the tank 
that routinely contains product;
    (2) For UST systems with a secondary barrier within the excavation 
zone, the sampling or testing method used can detect a leak between the 
UST system and the secondary barrier;
    (i) The secondary barrier around or beneath the UST system consists 
of artificially constructed material that is sufficiently thick and 
impermeable (at least 10-6 cm/sec for the regulated 
substance stored) to direct a leak to the monitoring point and permit 
its detection;
    (ii) The barrier is compatible with the regulated substance stored 
so that a leak from the UST system will not cause a deterioration of 
the barrier allowing a release to pass through undetected;
    (iii) For cathodically protected tanks, the secondary barrier must 
be installed so that it does not interfere with the proper operation of 
the cathodic protection system;
    (iv) The groundwater, soil moisture, or rainfall will not render 
the testing or sampling method used inoperative so that a release could 
go undetected for more than 30 days;
    (v) The site is assessed to ensure that the secondary barrier is 
always above the groundwater and not in a 25-year flood plain, unless 
the barrier and monitoring designs are for use under such conditions; 
and,
    (vi) Monitoring wells are clearly marked and secured to avoid 
unauthorized access and tampering.
    (3) For tanks with an internally fitted liner, an automated device 
can detect a leak between the inner wall of the tank and the liner, and 
the liner is compatible with the substance stored.
    (h) Statistical inventory reconciliation. Release detection methods 
based on the application of statistical principles to inventory data 
similar to those described in Sec.  280.43(a) must meet the following 
requirements:

[[Page 41636]]

    (1) Report a quantitative result with a calculated leak rate;
    (2) Be capable of detecting a leak rate of 0.2 gallon per hour or a 
release of 150 gallons within 30 days; and
    (3) Use a threshold that does not exceed one-half the minimum 
detectible leak rate.
    (i) Other methods. Any other type of release detection method, or 
combination of methods, can be used if:
    (1) It can detect a 0.2 gallon per hour leak rate or a release of 
150 gallons within a month with a probability of detection of 0.95 and 
a probability of false alarm of 0.05; or
    (2) The implementing agency may approve another method if the owner 
and operator can demonstrate that the method can detect a release as 
effectively as any of the methods allowed in paragraphs (c) through (h) 
of this section. In comparing methods, the implementing agency shall 
consider the size of release that the method can detect and the 
frequency and reliability with which it can be detected. If the method 
is approved, the owner and operator must comply with any conditions 
imposed by the implementing agency on its use to ensure the protection 
of human health and the environment.


Sec.  280.44  Methods of release detection for piping.

    Each method of release detection for piping used to meet the 
requirements of Sec.  280.41 must be conducted in accordance with the 
following:
    (a) Automatic line leak detectors. Methods which alert the operator 
to the presence of a leak by restricting or shutting off the flow of 
regulated substances through piping or triggering an audible or visual 
alarm may be used only if they detect leaks of 3 gallons per hour at 10 
pounds per square inch line pressure within 1 hour. An annual test of 
the operation of the leak detector must be conducted in accordance with 
Sec.  280.40(a)(3).
    (b) Line tightness testing. A periodic test of piping may be 
conducted only if it can detect a 0.1 gallon per hour leak rate at one 
and one-half times the operating pressure.
    (c) Applicable tank methods. Except as described in Sec.  
280.41(a), any of the methods in Sec.  280.43(e) through (i) may be 
used if they are designed to detect a release from any portion of the 
underground piping that routinely contains regulated substances.


Sec.  280.45  Release detection recordkeeping.

    All UST system owners and operators must maintain records in 
accordance with Sec.  280.34 demonstrating compliance with all 
applicable requirements of this subpart. These records must include the 
following:
    (a) All written performance claims pertaining to any release 
detection system used, and the manner in which these claims have been 
justified or tested by the equipment manufacturer or installer, must be 
maintained for 5 years, or for another reasonable period of time 
determined by the implementing agency, from the date of installation. 
Not later than October 13, 2018, records of site assessments required 
under Sec.  280.43(e)(6) and (f)(7) must be maintained for as long as 
the methods are used. Records of site assessments developed after 
October 13, 2015 must be signed by a professional engineer or 
professional geologist, or equivalent licensed professional with 
experience in environmental engineering, hydrogeology, or other 
relevant technical discipline acceptable to the implementing agency;
    (b) The results of any sampling, testing, or monitoring must be 
maintained for at least one year, or for another reasonable period of 
time determined by the implementing agency, except as follows:
    (1) The results of annual operation tests conducted in accordance 
with Sec.  280.40(a)(3) must be maintained for three years. At a 
minimum, the results must list each component tested, indicate whether 
each component tested meets criteria in Sec.  280.40(a)(3) or needs to 
have action taken, and describe any action taken to correct an issue; 
and
    (2) The results of tank tightness testing conducted in accordance 
with Sec.  280.43(c) must be retained until the next test is conducted; 
and
    (3) The results of tank tightness testing, line tightness testing, 
and vapor monitoring using a tracer compound placed in the tank system 
conducted in accordance with Sec.  280.252(d) must be retained until 
the next test is conducted; and
    (c) Written documentation of all calibration, maintenance, and 
repair of release detection equipment permanently located on-site must 
be maintained for at least one year after the servicing work is 
completed, or for another reasonable time period determined by the 
implementing agency. Any schedules of required calibration and 
maintenance provided by the release detection equipment manufacturer 
must be retained for five years from the date of installation.

Subpart E--Release Reporting, Investigation, and Confirmation


Sec.  280.50  Reporting of suspected releases.

    Owners and operators of UST systems must report to the implementing 
agency within 24 hours, or another reasonable period specified by the 
implementing agency, and follow the procedures in Sec.  280.52 for any 
of the following conditions:
    (a) The discovery by owners and operators or others of released 
regulated substances at the UST site or in the surrounding area (such 
as the presence of free product or vapors in soils, basements, sewer 
and utility lines, and nearby surface water).
    (b) Unusual operating conditions observed by owners and operators 
(such as the erratic behavior of product dispensing equipment, the 
sudden loss of product from the UST system, an unexplained presence of 
water in the tank, or liquid in the interstitial space of secondarily 
contained systems), unless:
    (1) The system equipment or component is found not to be releasing 
regulated substances to the environment;
    (2) Any defective system equipment or component is immediately 
repaired or replaced; and
    (3) For secondarily contained systems, except as provided for in 
Sec.  280.43(g)(2)(iv), any liquid in the interstitial space not used 
as part of the interstitial monitoring method (for example, brine 
filled) is immediately removed.
    (c) Monitoring results, including investigation of an alarm, from a 
release detection method required under Sec. Sec.  280.41 and 280.42 
that indicate a release may have occurred unless:
    (1) The monitoring device is found to be defective, and is 
immediately repaired, recalibrated or replaced, and additional 
monitoring does not confirm the initial result;
    (2) The leak is contained in the secondary containment and:
    (i) Except as provided for in Sec.  280.43(g)(2)(iv), any liquid in 
the interstitial space not used as part of the interstitial monitoring 
method (for example, brine filled) is immediately removed; and
    (ii) Any defective system equipment or component is immediately 
repaired or replaced;
    (3) In the case of inventory control described in Sec.  280.43(a), 
a second month of data does not confirm the initial result or the 
investigation determines no release has occurred; or
    (4) The alarm was investigated and determined to be a non-release 
event

[[Page 41637]]

(for example, from a power surge or caused by filling the tank during 
release detection testing).


Sec.  280.51  Investigation due to off-site impacts.

    When required by the implementing agency, owners and operators of 
UST systems must follow the procedures in Sec.  280.52 to determine if 
the UST system is the source of off-site impacts. These impacts include 
the discovery of regulated substances (such as the presence of free 
product or vapors in soils, basements, sewer and utility lines, and 
nearby surface and drinking waters) that has been observed by the 
implementing agency or brought to its attention by another party.


Sec.  280.52  Release investigation and confirmation steps.

    Unless corrective action is initiated in accordance with subpart F, 
owners and operators must immediately investigate and confirm all 
suspected releases of regulated substances requiring reporting under 
Sec.  280.50 within 7 days, or another reasonable time period specified 
by the implementing agency, using either the following steps or another 
procedure approved by the implementing agency:
    (a) System test. Owners and operators must conduct tests (according 
to the requirements for tightness testing in Sec. Sec.  280.43(c) and 
280.44(b) or, as appropriate, secondary containment testing described 
in Sec.  280.33(d)).
    (1) The test must determine whether:
    (i) A leak exists in that portion of the tank that routinely 
contains product, or the attached delivery piping; or
    (ii) A breach of either wall of the secondary containment has 
occurred.
    (2) If the system test confirms a leak into the interstice or a 
release, owners and operators must repair, replace, upgrade, or close 
the UST system. In addition, owners and operators must begin corrective 
action in accordance with subpart F of this part if the test results 
for the system, tank, or delivery piping indicate that a release 
exists.
    (3) Further investigation is not required if the test results for 
the system, tank, and delivery piping do not indicate that a release 
exists and if environmental contamination is not the basis for 
suspecting a release.
    (4) Owners and operators must conduct a site check as described in 
paragraph (b) of this section if the test results for the system, tank, 
and delivery piping do not indicate that a release exists but 
environmental contamination is the basis for suspecting a release.
    (b) Site check. Owners and operators must measure for the presence 
of a release where contamination is most likely to be present at the 
UST site. In selecting sample types, sample locations, and measurement 
methods, owners and operators must consider the nature of the stored 
substance, the type of initial alarm or cause for suspicion, the type 
of backfill, the depth of groundwater, and other factors appropriate 
for identifying the presence and source of the release.
    (1) If the test results for the excavation zone or the UST site 
indicate that a release has occurred, owners and operators must begin 
corrective action in accordance with subpart F of this part;
    (2) If the test results for the excavation zone or the UST site do 
not indicate that a release has occurred, further investigation is not 
required.


Sec.  280.53  Reporting and cleanup of spills and overfills.

    (a) Owners and operators of UST systems must contain and 
immediately clean up a spill or overfill and report to the implementing 
agency within 24 hours, or another reasonable time period specified by 
the implementing agency, and begin corrective action in accordance with 
subpart F of this part in the following cases:
    (1) Spill or overfill of petroleum that results in a release to the 
environment that exceeds 25 gallons or another reasonable amount 
specified by the implementing agency, or that causes a sheen on nearby 
surface water; and
    (2) Spill or overfill of a hazardous substance that results in a 
release to the environment that equals or exceeds its reportable 
quantity under CERCLA (40 CFR part 302).

    Note to paragraph (a). Pursuant to Sec. Sec.  302.6 and 355.40 
of this chapter, a release of a hazardous substance equal to or in 
excess of its reportable quantity must also be reported immediately 
(rather than within 24 hours) to the National Response Center under 
sections 102 and 103 of the Comprehensive Environmental Response, 
Compensation, and Liability Act of 1980 and to appropriate state and 
local authorities under Title III of the Superfund Amendments and 
Reauthorization Act of 1986.

    (b) Owners and operators of UST systems must contain and 
immediately clean up a spill or overfill of petroleum that is less than 
25 gallons or another reasonable amount specified by the implementing 
agency, and a spill or overfill of a hazardous substance that is less 
than the reportable quantity. If cleanup cannot be accomplished within 
24 hours, or another reasonable time period established by the 
implementing agency, owners and operators must immediately notify the 
implementing agency.

Subpart F--Release Response and Corrective Action for UST Systems 
Containing Petroleum or Hazardous Substances


Sec.  280.60  General.

    Owners and operators of petroleum or hazardous substance UST 
systems must, in response to a confirmed release from the UST system, 
comply with the requirements of this subpart except for USTs excluded 
under Sec.  280.10(b) and UST systems subject to RCRA Subtitle C 
corrective action requirements under section 3004(u) of the Resource 
Conservation and Recovery Act, as amended.


Sec.  280.61  Initial response.

    Upon confirmation of a release in accordance with Sec.  280.52 or 
after a release from the UST system is identified in any other manner, 
owners and operators must perform the following initial response 
actions within 24 hours of a release or within another reasonable 
period of time determined by the implementing agency:
    (a) Report the release to the implementing agency (e.g., by 
telephone or electronic mail);
    (b) Take immediate action to prevent any further release of the 
regulated substance into the environment; and
    (c) Identify and mitigate fire, explosion, and vapor hazards.


Sec.  280.62  Initial abatement measures and site check.

    (a) Unless directed to do otherwise by the implementing agency, 
owners and operators must perform the following abatement measures:
    (1) Remove as much of the regulated substance from the UST system 
as is necessary to prevent further release to the environment;
    (2) Visually inspect any aboveground releases or exposed 
belowground releases and prevent further migration of the released 
substance into surrounding soils and groundwater;
    (3) Continue to monitor and mitigate any additional fire and safety 
hazards posed by vapors or free product that have migrated from the UST 
excavation zone and entered into subsurface structures (such as sewers 
or basements);
    (4) Remedy hazards posed by contaminated soils that are excavated 
or exposed as a result of release confirmation, site investigation, 
abatement, or corrective action activities. If these remedies include 
treatment or disposal of soils, the owner and operator must comply with 
applicable state and local requirements;
    (5) Measure for the presence of a release where contamination is 
most

[[Page 41638]]

likely to be present at the UST site, unless the presence and source of 
the release have been confirmed in accordance with the site check 
required by Sec.  280.52(b) or the closure site assessment of Sec.  
280.72(a). In selecting sample types, sample locations, and measurement 
methods, the owner and operator must consider the nature of the stored 
substance, the type of backfill, depth to groundwater and other factors 
as appropriate for identifying the presence and source of the release; 
and
    (6) Investigate to determine the possible presence of free product, 
and begin free product removal as soon as practicable and in accordance 
with Sec.  280.64.
    (b) Within 20 days after release confirmation, or within another 
reasonable period of time determined by the implementing agency, owners 
and operators must submit a report to the implementing agency 
summarizing the initial abatement steps taken under paragraph (a) of 
this section and any resulting information or data.


Sec.  280.63  Initial site characterization.

    (a) Unless directed to do otherwise by the implementing agency, 
owners and operators must assemble information about the site and the 
nature of the release, including information gained while confirming 
the release or completing the initial abatement measures in Sec. Sec.  
280.60 and 280.61. This information must include, but is not 
necessarily limited to the following:
    (1) Data on the nature and estimated quantity of release;
    (2) Data from available sources and/or site investigations 
concerning the following factors: Surrounding populations, water 
quality, use and approximate locations of wells potentially affected by 
the release, subsurface soil conditions, locations of subsurface 
sewers, climatological conditions, and land use;
    (3) Results of the site check required under Sec.  280.62(a)(5); 
and
    (4) Results of the free product investigations required under Sec.  
280.62(a)(6), to be used by owners and operators to determine whether 
free product must be recovered under Sec.  280.64.
    (b) Within 45 days of release confirmation or another reasonable 
period of time determined by the implementing agency, owners and 
operators must submit the information collected in compliance with 
paragraph (a) of this section to the implementing agency in a manner 
that demonstrates its applicability and technical adequacy, or in a 
format and according to the schedule required by the implementing 
agency.


Sec.  280.64  Free product removal.

    At sites where investigations under Sec.  280.62(a)(6) indicate the 
presence of free product, owners and operators must remove free product 
to the maximum extent practicable as determined by the implementing 
agency while continuing, as necessary, any actions initiated under 
Sec. Sec.  280.61 through 280.63, or preparing for actions required 
under Sec. Sec.  280.65 through 280.66. In meeting the requirements of 
this section, owners and operators must:
    (a) Conduct free product removal in a manner that minimizes the 
spread of contamination into previously uncontaminated zones by using 
recovery and disposal techniques appropriate to the hydrogeologic 
conditions at the site, and that properly treats, discharges or 
disposes of recovery byproducts in compliance with applicable local, 
state, and federal regulations;
    (b) Use abatement of free product migration as a minimum objective 
for the design of the free product removal system;
    (c) Handle any flammable products in a safe and competent manner to 
prevent fires or explosions; and
    (d) Unless directed to do otherwise by the implementing agency, 
prepare and submit to the implementing agency, within 45 days after 
confirming a release, a free product removal report that provides at 
least the following information:
    (1) The name of the person(s) responsible for implementing the free 
product removal measures;
    (2) The estimated quantity, type, and thickness of free product 
observed or measured in wells, boreholes, and excavations;
    (3) The type of free product recovery system used;
    (4) Whether any discharge will take place on-site or off-site 
during the recovery operation and where this discharge will be located;
    (5) The type of treatment applied to, and the effluent quality 
expected from, any discharge;
    (6) The steps that have been or are being taken to obtain necessary 
permits for any discharge; and
    (7) The disposition of the recovered free product.


Sec.  280.65  Investigations for soil and groundwater cleanup.

    (a) In order to determine the full extent and location of soils 
contaminated by the release and the presence and concentrations of 
dissolved product contamination in the groundwater, owners and 
operators must conduct investigations of the release, the release site, 
and the surrounding area possibly affected by the release if any of the 
following conditions exist:
    (1) There is evidence that groundwater wells have been affected by 
the release (e.g., as found during release confirmation or previous 
corrective action measures);
    (2) Free product is found to need recovery in compliance with Sec.  
280.64;
    (3) There is evidence that contaminated soils may be in contact 
with groundwater (e.g., as found during conduct of the initial response 
measures or investigations required under Sec. Sec.  280.60 through 
280.64); and
    (4) The implementing agency requests an investigation, based on the 
potential effects of contaminated soil or groundwater on nearby surface 
water and groundwater resources.
    (b) Owners and operators must submit the information collected 
under paragraph (a) of this section as soon as practicable or in 
accordance with a schedule established by the implementing agency.


Sec.  280.66  Corrective action plan.

    (a) At any point after reviewing the information submitted in 
compliance with Sec. Sec.  280.61 through 280.63, the implementing 
agency may require owners and operators to submit additional 
information or to develop and submit a corrective action plan for 
responding to contaminated soils and groundwater. If a plan is 
required, owners and operators must submit the plan according to a 
schedule and format established by the implementing agency. 
Alternatively, owners and operators may, after fulfilling the 
requirements of Sec. Sec.  280.61 through 280.63, choose to submit a 
corrective action plan for responding to contaminated soil and 
groundwater. In either case, owners and operators are responsible for 
submitting a plan that provides for adequate protection of human health 
and the environment as determined by the implementing agency, and must 
modify their plan as necessary to meet this standard.
    (b) The implementing agency will approve the corrective action plan 
only after ensuring that implementation of the plan will adequately 
protect human health, safety, and the environment. In making this 
determination, the implementing agency should consider the following 
factors as appropriate:
    (1) The physical and chemical characteristics of the regulated

[[Page 41639]]

substance, including its toxicity, persistence, and potential for 
migration;
    (2) The hydrogeologic characteristics of the facility and the 
surrounding area;
    (3) The proximity, quality, and current and future uses of nearby 
surface water and groundwater;
    (4) The potential effects of residual contamination on nearby 
surface water and groundwater;
    (5) An exposure assessment; and
    (6) Any information assembled in compliance with this subpart.
    (c) Upon approval of the corrective action plan or as directed by 
the implementing agency, owners and operators must implement the plan, 
including modifications to the plan made by the implementing agency. 
They must monitor, evaluate, and report the results of implementing the 
plan in accordance with a schedule and in a format established by the 
implementing agency.
    (d) Owners and operators may, in the interest of minimizing 
environmental contamination and promoting more effective cleanup, begin 
cleanup of soil and groundwater before the corrective action plan is 
approved provided that they:
    (1) Notify the implementing agency of their intention to begin 
cleanup;
    (2) Comply with any conditions imposed by the implementing agency, 
including halting cleanup or mitigating adverse consequences from 
cleanup activities; and
    (3) Incorporate these self-initiated cleanup measures in the 
corrective action plan that is submitted to the implementing agency for 
approval.


Sec.  280.67  Public participation.

    (a) For each confirmed release that requires a corrective action 
plan, the implementing agency must provide notice to the public by 
means designed to reach those members of the public directly affected 
by the release and the planned corrective action. This notice may 
include, but is not limited to, public notice in local newspapers, 
block advertisements, public service announcements, publication in a 
state register, letters to individual households, or personal contacts 
by field staff.
    (b) The implementing agency must ensure that site release 
information and decisions concerning the corrective action plan are 
made available to the public for inspection upon request.
    (c) Before approving a corrective action plan, the implementing 
agency may hold a public meeting to consider comments on the proposed 
corrective action plan if there is sufficient public interest, or for 
any other reason.
    (d) The implementing agency must give public notice that complies 
with paragraph (a) of this section if implementation of an approved 
corrective action plan does not achieve the established cleanup levels 
in the plan and termination of that plan is under consideration by the 
implementing agency.

Subpart G--Out-of-Service UST Systems and Closure


Sec.  280.70  Temporary closure.

    (a) When an UST system is temporarily closed, owners and operators 
must continue operation and maintenance of corrosion protection in 
accordance with Sec.  280.31, and any release detection in accordance 
with subparts D and K of this part. Subparts E and F of this part must 
be complied with if a release is suspected or confirmed. However, 
release detection and release detection operation and maintenance 
testing and inspections in subparts C and D of this part are not 
required as long as the UST system is empty. The UST system is empty 
when all materials have been removed using commonly employed practices 
so that no more than 2.5 centimeters (one inch) of residue, or 0.3 
percent by weight of the total capacity of the UST system, remain in 
the system. In addition, spill and overfill operation and maintenance 
testing and inspections in subpart C of this part are not required.
    (b) When an UST system is temporarily closed for 3 months or more, 
owners and operators must also comply with the following requirements:
    (1) Leave vent lines open and functioning; and
    (2) Cap and secure all other lines, pumps, manways, and ancillary 
equipment.
    (c) When an UST system is temporarily closed for more than 12 
months, owners and operators must permanently close the UST system if 
it does not meet either performance standards in Sec.  280.20 for new 
UST systems or the upgrading requirements in Sec.  280.21, except that 
the spill and overfill equipment requirements do not have to be met. 
Owners and operators must permanently close the substandard UST systems 
at the end of this 12-month period in accordance with Sec. Sec.  280.71 
through 280.74, unless the implementing agency provides an extension of 
the 12-month temporary closure period. Owners and operators must 
complete a site assessment in accordance with Sec.  280.72 before such 
an extension can be applied for.


Sec.  280.71  Permanent closure and changes-in-service.

    (a) At least 30 days before beginning either permanent closure or a 
change-in-service under paragraphs (b) and (c) of this section, or 
within another reasonable time period determined by the implementing 
agency, owners and operators must notify the implementing agency of 
their intent to permanently close or make the change-in-service, unless 
such action is in response to corrective action. The required 
assessment of the excavation zone under Sec.  280.72 must be performed 
after notifying the implementing agency but before completion of the 
permanent closure or a change-in-service.
    (b) To permanently close a tank, owners and operators must empty 
and clean it by removing all liquids and accumulated sludges. All tanks 
taken out of service permanently must: be removed from the ground, 
filled with an inert solid material, or closed in place in a manner 
approved by the implementing agency.
    (c) Continued use of an UST system to store a non-regulated 
substance is considered a change-in-service. Before a change-in-
service, owners and operators must empty and clean the tank by removing 
all liquid and accumulated sludge and conduct a site assessment in 
accordance with Sec.  280.72.

    Note to Sec.  280.71.  The following cleaning and closure 
procedures may be used to comply with this section:
    (A) American Petroleum Institute Recommended Practice RP 1604, 
``Closure of Underground Petroleum Storage Tanks'';
    (B) American Petroleum Institute Standard 2015, ``Safe Entry and 
Cleaning of Petroleum Storage Tanks, Planning and Managing Tank 
Entry From Decommissioning Through Recommissioning'';
    (C) American Petroleum Institute Recommended Practice 2016, 
``Guidelines and Procedures for Entering and Cleaning Petroleum 
Storage Tanks'';
    (D) American Petroleum Institute Recommended Practice RP 1631, 
``Interior Lining and Periodic Inspection of Underground Storage 
Tanks,'' may be used as guidance for compliance with this section;
    (E) National Fire Protection Association Standard 326, 
``Standard for the Safeguarding of Tanks and Containers for Entry, 
Cleaning, or Repair''; and
    (F) National Institute for Occupational Safety and Health 
Publication 80-106, ``Criteria for a Recommended Standard . . . 
Working in Confined Space'' may be used as guidance for conducting 
safe closure procedures at some hazardous substance tanks.

Sec.  280.72  Assessing the site at closure or change-in-service.

    (a) Before permanent closure or a change-in-service is completed, 
owners

[[Page 41640]]

and operators must measure for the presence of a release where 
contamination is most likely to be present at the UST site. In 
selecting sample types, sample locations, and measurement methods, 
owners and operators must consider the method of closure, the nature of 
the stored substance, the type of backfill, the depth to groundwater, 
and other factors appropriate for identifying the presence of a 
release. The requirements of this section are satisfied if one of the 
external release detection methods allowed in Sec.  280.43(e) and (f) 
is operating in accordance with the requirements in Sec.  280.43 at the 
time of closure, and indicates no release has occurred.
    (b) If contaminated soils, contaminated groundwater, or free 
product as a liquid or vapor is discovered under paragraph (a) of this 
section, or by any other manner, owners and operators must begin 
corrective action in accordance with subpart F of this part.


Sec.  280.73  Applicability to previously closed UST systems.

    When directed by the implementing agency, the owner and operator of 
an UST system permanently closed before December 22, 1988 must assess 
the excavation zone and close the UST system in accordance with this 
subpart if releases from the UST may, in the judgment of the 
implementing agency, pose a current or potential threat to human health 
and the environment.


Sec.  280.74  Closure records.

    Owners and operators must maintain records in accordance with Sec.  
280.34 that are capable of demonstrating compliance with closure 
requirements under this subpart. The results of the excavation zone 
assessment required in Sec.  280.72 must be maintained for at least 
three years after completion of permanent closure or change-in-service 
in one of the following ways:
    (a) By the owners and operators who took the UST system out of 
service;
    (b) By the current owners and operators of the UST system site; or
    (c) By mailing these records to the implementing agency if they 
cannot be maintained at the closed facility.

Subpart H--Financial Responsibility


Sec.  280.90  Applicability.

    (a) This subpart applies to owners and operators of all petroleum 
underground storage tank (UST) systems except as otherwise provided in 
this section.
    (b) Owners and operators of petroleum UST systems are subject to 
these requirements in accordance with Sec.  280.91.
    (c) State and Federal government entities whose debts and 
liabilities are the debts and liabilities of a state or the United 
States are exempt from the requirements of this subpart.
    (d) The requirements of this subpart do not apply to owners and 
operators of any UST system described in Sec.  280.10(b), (c)(1), 
(c)(3), or (c)(4).
    (e) If the owner and operator of a petroleum underground storage 
tank are separate persons, only one person is required to demonstrate 
financial responsibility; however, both parties are liable in event of 
noncompliance.


Sec.  280.91  Compliance dates.

    Owners of petroleum underground storage tanks must comply with the 
requirements of this subpart. Previously deferred UST systems must 
comply with the requirements of this subpart according to the schedule 
in Sec.  280.251(a).


Sec.  280.92  Definition of terms.

    When used in this subpart, the following terms shall have the 
meanings given below:
    Accidental release means any sudden or nonsudden release of 
petroleum arising from operating an underground storage tank that 
results in a need for corrective action and/or compensation for bodily 
injury or property damage neither expected nor intended by the tank 
owner or operator.
    Bodily injury shall have the meaning given to this term by 
applicable state law; however, this term shall not include those 
liabilities which, consistent with standard insurance industry 
practices, are excluded from coverage in liability insurance policies 
for bodily injury.
    Chief Financial Officer, in the case of local government owners and 
operators, means the individual with the overall authority and 
responsibility for the collection, disbursement, and use of funds by 
the local government.
    Controlling interest means direct ownership of at least 50 percent 
of the voting stock of another entity.
    Director of the Implementing Agency means the EPA Regional 
Administrator, or, in the case of a state with a program approved under 
section 9004, the Director of the designated state or local agency 
responsible for carrying out an approved UST program.
    Financial reporting year means the latest consecutive twelve-month 
period for which any of the following reports used to support a 
financial test is prepared:
    (1) A 10-K report submitted to the SEC;
    (2) An annual report of tangible net worth submitted to Dun and 
Bradstreet; or
    (3) Annual reports submitted to the Energy Information 
Administration or the Rural Utilities Service.
    Note to the definition of Financial reporting year. ``Financial 
reporting year'' may thus comprise a fiscal or a calendar year period.
    Legal defense cost is any expense that an owner or operator or 
provider of financial assurance incurs in defending against claims or 
actions brought:
    (1) By EPA or a state to require corrective action or to recover 
the costs of corrective action;
    (2) By or on behalf of a third party for bodily injury or property 
damage caused by an accidental release; or
    (3) By any person to enforce the terms of a financial assurance 
mechanism.
    Local government shall have the meaning given this term by 
applicable state law and includes Indian tribes. The term is generally 
intended to include:
    (1) Counties, municipalities, townships, separately chartered and 
operated special districts (including local government public transit 
systems and redevelopment authorities), and independent school 
districts authorized as governmental bodies by state charter or 
constitution; and
    (2) Special districts and independent school districts established 
by counties, municipalities, townships, and other general purpose 
governments to provide essential services.
    Occurrence means an accident, including continuous or repeated 
exposure to conditions, which results in a release from an underground 
storage tank.
    Note to the definition of Occurrence. This definition is intended 
to assist in the understanding of these regulations and is not intended 
either to limit the meaning of ``occurrence'' in a way that conflicts 
with standard insurance usage or to prevent the use of other standard 
insurance terms in place of ``occurrence.''
    Owner or operator, when the owner or operator are separate parties, 
refers to the party that is obtaining or has obtained financial 
assurances.
    Petroleum marketing facilities include all facilities at which 
petroleum is produced or refined and all facilities from which 
petroleum is sold or transferred to other petroleum marketers or to the 
public.
    Property damage shall have the meaning given this term by 
applicable state law. This term shall not include those liabilities 
which, consistent with standard insurance industry practices,

[[Page 41641]]

are excluded from coverage in liability insurance policies for property 
damage. However, such exclusions for property damage shall not include 
corrective action associated with releases from tanks which are covered 
by the policy.
    Provider of financial assurance means an entity that provides 
financial assurance to an owner or operator of an underground storage 
tank through one of the mechanisms listed in Sec. Sec.  280.95 through 
280.107, including a guarantor, insurer, risk retention group, surety, 
issuer of a letter of credit, issuer of a state-required mechanism, or 
a state.
    Substantial business relationship means the extent of a business 
relationship necessary under applicable state law to make a guarantee 
contract issued incident to that relationship valid and enforceable. A 
guarantee contract is issued ``incident to that relationship'' if it 
arises from and depends on existing economic transactions between the 
guarantor and the owner or operator.
    Substantial governmental relationship means the extent of a 
governmental relationship necessary under applicable state law to make 
an added guarantee contract issued incident to that relationship valid 
and enforceable. A guarantee contract is issued ``incident to that 
relationship'' if it arises from a clear commonality of interest in the 
event of an UST release such as coterminous boundaries, overlapping 
constituencies, common groundwater aquifer, or other relationship other 
than monetary compensation that provides a motivation for the guarantor 
to provide a guarantee.
    Tangible net worth means the tangible assets that remain after 
deducting liabilities; such assets do not include intangibles such as 
goodwill and rights to patents or royalties. For purposes of this 
definition, ``assets'' means all existing and all probable future 
economic benefits obtained or controlled by a particular entity as a 
result of past transactions.
    Termination under Sec.  280.97(b)(1) and (2) means only those 
changes that could result in a gap in coverage as where the insured has 
not obtained substitute coverage or has obtained substitute coverage 
with a different retroactive date than the retroactive date of the 
original policy.


Sec.  280.93  Amount and scope of required financial responsibility.

    (a) Owners or operators of petroleum underground storage tanks must 
demonstrate financial responsibility for taking corrective action and 
for compensating third parties for bodily injury and property damage 
caused by accidental releases arising from the operation of petroleum 
underground storage tanks in at least the following per-occurrence 
amounts:
    (1) For owners or operators of petroleum underground storage tanks 
that are located at petroleum marketing facilities, or that handle an 
average of more than 10,000 gallons of petroleum per month based on 
annual throughput for the previous calendar year; $1 million.
    (2) For all other owners or operators of petroleum underground 
storage tanks; $500,000.
    (b) Owners or operators of petroleum underground storage tanks must 
demonstrate financial responsibility for taking corrective action and 
for compensating third parties for bodily injury and property damage 
caused by accidental releases arising from the operation of petroleum 
underground storage tanks in at least the following annual aggregate 
amounts:
    (1) For owners or operators of 1 to 100 petroleum underground 
storage tanks, $1 million; and
    (2) For owners or operators of 101 or more petroleum underground 
storage tanks, $2 million.
    (c) For the purposes of paragraphs (b) and (f) of this section, 
only, ``a petroleum underground storage tank'' means a single 
containment unit and does not mean combinations of single containment 
units.
    (d) Except as provided in paragraph (e) of this section, if the 
owner or operator uses separate mechanisms or separate combinations of 
mechanisms to demonstrate financial responsibility for:
    (1) Taking corrective action;
    (2) Compensating third parties for bodily injury and property 
damage caused by sudden accidental releases; or
    (3) Compensating third parties for bodily injury and property 
damage caused by nonsudden accidental releases, the amount of assurance 
provided by each mechanism or combination of mechanisms must be in the 
full amount specified in paragraphs (a) and (b) of this section.
    (e) If an owner or operator uses separate mechanisms or separate 
combinations of mechanisms to demonstrate financial responsibility for 
different petroleum underground storage tanks, the annual aggregate 
required shall be based on the number of tanks covered by each such 
separate mechanism or combination of mechanisms.
    (f) Owners or operators shall review the amount of aggregate 
assurance provided whenever additional petroleum underground storage 
tanks are acquired or installed. If the number of petroleum underground 
storage tanks for which assurance must be provided exceeds 100, the 
owner or operator shall demonstrate financial responsibility in the 
amount of at least $2 million of annual aggregate assurance by the 
anniversary of the date on which the mechanism demonstrating financial 
responsibility became effective. If assurance is being demonstrated by 
a combination of mechanisms, the owner or operator shall demonstrate 
financial responsibility in the amount of at least $2 million of annual 
aggregate assurance by the first-occurring effective date anniversary 
of any one of the mechanisms combined (other than a financial test or 
guarantee) to provide assurance.
    (g) The amounts of assurance required under this section exclude 
legal defense costs.
    (h) The required per-occurrence and annual aggregate coverage 
amounts do not in any way limit the liability of the owner or operator.


Sec.  280.94  Allowable mechanisms and combinations of mechanisms.

    (a) Subject to the limitations of paragraphs (b) and (c) of this 
section:
    (1) An owner or operator, including a local government owner or 
operator, may use any one or combination of the mechanisms listed in 
Sec. Sec.  280.95 through 280.103 to demonstrate financial 
responsibility under this subpart for one or more underground storage 
tanks; and
    (2) A local government owner or operator may use any one or 
combination of the mechanisms listed in Sec. Sec.  280.104 through 
280.107 to demonstrate financial responsibility under this subpart for 
one or more underground storage tanks.
    (b) An owner or operator may use a guarantee under Sec.  280.96 or 
surety bond under Sec.  280.98 to establish financial responsibility 
only if the Attorney(s) General of the state(s) in which the 
underground storage tanks are located has (have) submitted a written 
statement to the implementing agency that a guarantee or surety bond 
executed as described in this section is a legally valid and 
enforceable obligation in that state.
    (c) An owner or operator may use self-insurance in combination with 
a guarantee only if, for the purpose of meeting the requirements of the 
financial test under this rule, the financial statements of the owner 
or operator are not consolidated with the financial statements of the 
guarantor.


Sec.  280.95  Financial test of self-insurance.

    (a) An owner or operator, and/or guarantor, may satisfy the 
requirements

[[Page 41642]]

operator, and/or guarantor must meet the criteria of paragraph (b) or 
(c) of this section based on year-end financial statements for the 
latest completed fiscal year.
    (b)(1) The owner or operator, and/or guarantor, must have a 
tangible net worth of at least ten times:
    (i) The total of the applicable aggregate amount required by Sec.  
280.93, based on the number of underground storage tanks for which a 
financial test is used to demonstrate financial responsibility to EPA 
under this section or to a state implementing agency under a state 
program approved by EPA under 40 CFR part 281;
    (ii) The sum of the corrective action cost estimates, the current 
closure and post-closure care cost estimates, and amount of liability 
coverage for which a financial test is used to demonstrate financial 
responsibility to EPA under 40 CFR 264.101, 264.143, 264.145, 265.143, 
265.145, 264.147, and 265.147 or to a state implementing agency under a 
state program authorized by EPA under 40 CFR part 271; and
    (iii) The sum of current plugging and abandonment cost estimates

    (e) If an owner or operator using the test to provide financial 
assurance finds that he or she no longer meets the requirements of the 
financial test based on the year-end financial statements, the owner or 
operator must obtain alternative coverage within 150 days of the end of 
the year for which financial statements have been prepared.
    (f) The Director of the implementing agency may require reports of 
financial condition at any time from the owner or operator, and/or 
guarantor. If the Director finds, on the basis of such reports or other 
information, that the owner or operator, and/or guarantor, no longer 
meets the financial test requirements of Sec.  280.95(b) or (c) and 
(d), the owner or operator must obtain alternate coverage within 30 
days after notification of such a finding.
    (g) If the owner or operator fails to obtain alternate assurance 
within 150 days of finding that he or she no longer meets the 
requirements of the financial test based on the year-end financial 
statements, or within 30 days of notification by the Director of the 
implementing agency that he or she no longer meets the requirements of 
the financial test, the owner or operator must notify the Director of 
such failure within 10 days.


Sec.  280.96  Guarantee.

    (a) An owner or operator may satisfy the requirements of Sec.  
280.93 by obtaining a guarantee that conforms to the requirements of 
this section. The guarantor must be:
    (1) A firm that:
    (i) Possesses a controlling interest in the owner or operator;
    (ii) Possesses a controlling interest in a firm described under 
paragraph (a)(1)(i) of this section; or,
    (iii) Is controlled through stock ownership by a common parent firm 
that possesses a controlling interest in the owner or operator; or,
    (2) A firm engaged in a substantial business relationship with the 
owner or operator and issuing the guarantee as an act incident to that 
business relationship.
    (b) Within 120 days of the close of each financial reporting year 
the guarantor must demonstrate that it meets the financial test 
criteria of Sec.  280.95 based on year-end financial statements for the 
latest completed financial reporting year by completing the letter from 
the chief financial officer described in Sec.  280.95(d) and must 
deliver the letter to the owner or operator. If the guarantor fails to 
meet the requirements of the financial test at the end of any financial 
reporting year, within 120 days of the end of that financial reporting 
year the guarantor shall send by certified mail, before cancellation or 
nonrenewal of the guarantee, notice to the owner or operator. If the 
Director of the implementing agency notifies the guarantor that he no 
longer meets the requirements of the financial test of Sec.  280.95(b) 
or (c) and (d), the guarantor must notify the owner or operator within 
10 days of receiving such notification from the Director. In both 
cases, the guarantee will terminate no less than 120 days after the 
date the owner or operator receives the notification, as evidenced by 
the return receipt. The owner or operator must obtain alternative 
coverage as specified in Sec.  280.114(e).
    (c) The guarantee must be worded as follows, except that 
instructions in brackets are to be replaced with the relevant 
information and the brackets deleted:

[[Page 41644]]

     Guarantee
    Guarantee made this [date] by [name of guaranteeing entity], a 
business entity organized under the laws of the state of [name of 
state], herein referred to as guarantor, to [the state implementing 
agency] and to any and all third parties, and obligees, on behalf of 
[owner or operator] of [business address].
     Recitals.
    (1) Guarantor meets or exceeds the financial test criteria of 40 
CFR 280.95(b) or (c) and (d) and agrees to comply with the requirements 
for guarantors as specified in 40 CFR 280.96(b).
    (2) [Owner or operator] owns or operates the following underground 
storage tank(s) covered by this guarantee: [List the number of tanks at 
each facility and the name(s) and address(es) of the facility(ies) 
where the tanks are located. If more than one instrument is used to 
assure different tanks at any one facility, for each tank covered by 
this instrument, list the tank identification number provided in the 
notification submitted pursuant to 40 CFR 280.22 or the corresponding 
state requirement, and the name and address of the facility.] This 
guarantee satisfies 40 CFR part 280, subpart H requirements for 
assuring funding for [insert: ``taking corrective action'' and/or 
``compensating third parties for bodily injury and property damage 
caused by'' either ``sudden accidental releases'' or ``nonsudden 
accidental releases'' or ``accidental releases''; if coverage is 
different for different tanks or locations, indicate the type of 
coverage applicable to each tank or location] arising from operating 
the above-identified underground storage tank(s) in the amount of 
[insert dollar amount] per occurrence and [insert dollar amount] annual 
aggregate.
    (3) [Insert appropriate phrase: ``On behalf of our subsidiary'' (if 
guarantor is corporate parent of the owner or operator); ``On behalf of 
our affiliate'' (if guarantor is a related firm of the owner or 
operator); or ``Incident to our business relationship with'' (if 
guarantor is providing the guarantee as an incident to a substantial 
business relationship with owner or operator)] [owner or operator], 
guarantor guarantees to [implementing agency] and to any and all third 
parties that:
    In the event that [owner or operator] fails to provide alternative 
coverage within 60 days after receipt of a notice of cancellation of 
this guarantee and the [Director of the implementing agency] has 
determined or suspects that a release has occurred at an underground 
storage tank covered by this guarantee, the guarantor, upon 
instructions from the [Director], shall fund a standby trust fund in 
accordance with the provisions of 40 CFR 280.112, in an amount not to 
exceed the coverage limits specified above.
    In the event that the [Director] determines that [owner or 
operator] has failed to perform corrective action for releases arising 
out of the operation of the above-identified tank(s) in accordance with 
40 CFR part 280, subpart F, the guarantor upon written instructions 
from the [Director] shall fund a standby trust in accordance with the 
provisions of 40 CFR 280.112, in an amount not to exceed the coverage 
limits specified above.
    If [owner or operator] fails to satisfy a judgment or award based 
on a determination of liability for bodily injury or property damage to 
third parties caused by [``sudden'' and/or ``nonsudden''] accidental 
releases arising from the operation of the above-identified tank(s), or 
fails to pay an amount agreed to in settlement of a claim arising from 
or alleged to arise from such injury or damage, the guarantor, upon 
written instructions from the [Director], shall fund a standby trust in 
accordance with the provisions of 40 CFR 280.112 to satisfy such 
judgment(s), award(s), or settlement agreement(s) up to the limits of 
coverage specified above.
    (4) Guarantor agrees that if, at the end of any fiscal year before 
cancellation of this guarantee, the guarantor fails to meet the 
financial test criteria of 40 CFR 280.95(b) or (c) and (d), guarantor 
shall send within 120 days of such failure, by certified mail, notice 
to [owner or operator]. The guarantee will terminate 120 days from the 
date of receipt of the notice by [owner or operator], as evidenced by 
the return receipt.
    (5) Guarantor agrees to notify [owner or operator] by certified 
mail of a voluntary or involuntary proceeding under Title 11 
(Bankruptcy), U.S. Code naming guarantor as debtor, within 10 days 
after commencement of the proceeding.
    (6) Guarantor agrees to remain bound under this guarantee 
notwithstanding any modification or alteration of any obligation of 
[owner or operator] pursuant to 40 CFR part 280.
    (7) Guarantor agrees to remain bound under this guarantee for so 
long as [owner or operator] must comply with the applicable financial 
responsibility requirements of 40 CFR part 280, subpart H for the 
above-identified tank(s), except that guarantor may cancel this 
guarantee by sending notice by certified mail to [owner or operator], 
such cancellation to become effective no earlier than 120 days after 
receipt of such notice by [owner or operator], as evidenced by the 
return receipt.
    (8) The guarantor's obligation does not apply to any of the 
following:
    (a) Any obligation of [insert owner or operator] under a workers' 
compensation, disability benefits, or unemployment compensation law or 
other similar law;
    (b) Bodily injury to an employee of [insert owner or operator] 
arising from, and in the course of, employment by [insert owner or 
operator];
    (c) Bodily injury or property damage arising from the ownership, 
maintenance, use, or entrustment to others of any aircraft, motor 
vehicle, or watercraft;
    (d) Property damage to any property owned, rented, loaded to, in 
the care, custody, or control of, or occupied by [insert owner or 
operator] that is not the direct result of a release from a petroleum 
underground storage tank;
    (e) Bodily damage or property damage for which [insert owner or 
operator] is obligated to pay damages by reason of the assumption of 
liability in a contract or agreement other than a contract or agreement 
entered into to meet the requirements of 40 CFR 280.93.
    (9) Guarantor expressly waives notice of acceptance of this 
guarantee by [the implementing agency], by any or all third parties, or 
by [owner or operator].
    I hereby certify that the wording of this guarantee is identical to 
the wording specified in 40 CFR 280.96(c) as such regulations were 
constituted on the effective date shown immediately below.

damage caused by'' either ``sudden accidental releases'' or ``nonsudden 
accidental releases'' or ``accidental releases''; in accordance with 
and subject to the limits of liability, exclusions, conditions, and 
other terms of the policy; if coverage is different for different tanks 
or locations, indicate the type of coverage applicable to each tank or 
location] arising from operating the underground storage tank(s) 
identified above.
    The limits of liability are [insert the dollar amount of the ``each

    2. The insurance afforded with respect to such occurrences is

amounts within any deductible applicable to the policy to the provider

written notice is received by the insured. Cancellation for non-payment 
of premium or misrepresentation by the insured will be effective only 
upon written notice and only after expiration of a minimum of 10 days 
after a copy of such written notice is received by the insured.

[Insert for claims-made policies:
    e. The insurance covers claims otherwise covered by the policy that 
are reported to the [``Insurer'' or ``Group''] within six months of the 
effective date of cancellation or non-renewal of the policy except 
where the new or renewed policy has the same retroactive date or a 
retroactive date earlier than that of the prior policy, and which arise 
out of any covered occurrence that commenced after the policy 
retroactive date, if applicable, and prior to such policy renewal or 
termination date. Claims reported during such extended reporting period 
are subject to the terms, conditions, limits, including limits of 
liability, and exclusions of the policy.]
    I hereby certify that the wording of this instrument is identical 
to the wording in 40 CFR 280.97(b)(1) and that the [``Insurer'' or

    Know All Persons by These Presents, that we, the Principal and 
Surety(ies), hereto are firmly bound to [the implementing agency], in 
the above penal sums for the payment of which we bind ourselves, our 
heirs, executors, administrators, successors, and assigns jointly and 
severally; provided that, where the Surety(ies) are corporations acting 
as co-sureties, we, the Sureties, bind ourselves in such sums jointly 
and severally only for the purpose of allowing a joint action or 
actions against any or all of us, and for all other purposes each 
Surety binds itself,

[[Page 41647]]

jointly and severally with the Principal, for the payment of such sums 
only as is set forth opposite the name of such Surety, but if no limit 
of liability is indicated, the limit of liability shall be the full 
amount of the penal sums.
    Whereas said Principal is required under Subtitle I of the Solid 
Waste Disposal Act, as amended, to provide financial assurance for 
[insert: ``taking corrective action'' and/or ``compensating third 
parties for bodily injury and property damage caused by'' either 
``sudden accidental releases'' or ``nonsudden accidental releases'' or 
``accidental releases''; if coverage is different for different tanks 
or locations, indicate the type of coverage applicable to each tank or 
location] arising from operating the underground storage tanks 
identified above, and
    Whereas said Principal shall establish a standby trust fund as is 
required when a surety bond is used to provide such financial 
assurance;
    Now, therefore, the conditions of the obligation are such that if 
the Principal shall faithfully [``take corrective action, in accordance 
with 40 CFR part 280, subpart F and the Director of the state 
implementing agency's instructions for,'' and/or ``compensate injured 
third parties for bodily injury and property damage caused by'' either 
``sudden accidental releases'' or ``nonsudden accidental releases'' or 
``accidental releases''] arising from operating the tank(s) identified 
above, or if the Principal shall provide alternate financial assurance, 
as specified in 40 CFR part 280, subpart H, within 120 days after the 
date the notice of cancellation is received by the Principal from the 
Surety(ies), then this obligation shall be null and void; otherwise it 
is to remain in full force and effect.
    Such obligation does not apply to any of the following:
    (a) Any obligation of [insert owner or operator] under a workers' 
compensation, disability benefits, or unemployment compensation law or 
other similar law;
    (b) Bodily injury to an employee of [insert owner or operator] 
arising from, and in the course of, employment by [insert owner or 
operator];
    (c) Bodily injury or property damage arising from the ownership, 
maintenance, use, or entrustment to others of any aircraft, motor 
vehicle, or watercraft;
    (d) Property damage to any property owned, rented, loaned to, in 
the care, custody, or control of, or occupied by [insert owner or 
operator] that is not the direct result of a release from a petroleum 
underground storage tank;
    (e) Bodily injury or property damage for which [insert owner or 
operator] is obligated to pay damages by reason of the assumption of 
liability in a contract or agreement other than a contract or agreement 
entered into to meet the requirements of 40 CFR 280.93.
    The Surety(ies) shall become liable on this bond obligation only 
when the Principal has failed to fulfill the conditions described 
above.
    Upon notification by [the Director of the implementing agency] that 
the Principal has failed to [``take corrective action, in accordance 
with 40 CFR part 280, subpart F and the Director's instructions,'' and/
or ``compensate injured third parties''] as guaranteed by this bond, 
the Surety(ies) shall either perform [``corrective action in accordance 
with 40 CFR part 280 and the Director's instructions,'' and/or ``third-
party liability compensation''] or place funds in an amount up to the 
annual aggregate penal sum into the standby trust fund as directed by 
[the Regional Administrator or the Director] under 40 CFR 280.112.
    Upon notification by [the Director] that the Principal has failed 
to provide alternate financial assurance within 60 days after the date 
the notice of cancellation is received by the Principal from the 
Surety(ies) and that [the Director] has determined or suspects that a 
release has occurred, the Surety(ies) shall place funds in an amount 
not exceeding the annual aggregate penal sum into the standby trust 
fund as directed by [the Director] under 40 CFR 280.112.
    The Surety(ies) hereby waive(s) notification of amendments to 
applicable laws, statutes, rules, and regulations and agrees that no 
such amendment shall in any way alleviate its (their) obligation on 
this bond.
    The liability of the Surety(ies) shall not be discharged by any 
payment or succession of payments hereunder, unless and until such 
payment or payments shall amount in the annual aggregate to the penal 
sum shown on the face of the bond, but in no event shall the obligation 
of the Surety(ies) hereunder exceed the amount of said annual aggregate 
penal sum.
    The Surety(ies) may cancel the bond by sending notice of 
cancellation by certified mail to the Principal, provided, however, 
that cancellation shall not occur during the 120 days beginning on the 
date of receipt of the notice of cancellation by the Principal, as 
evidenced by the return receipt.
    The Principal may terminate this bond by sending written notice to 
the Surety(ies).
    In Witness Thereof, the Principal and Surety(ies) have executed 
this Bond and have affixed their seals on the date set forth above.
    The persons whose signatures appear below hereby certify that they 
are authorized to execute this surety bond on behalf of the Principal 
and Surety(ies) and that the wording of this surety bond is identical

    (c) Under the terms of the bond, the surety will become liable on 
the bond obligation when the owner or operator fails to perform as 
guaranteed by the bond. In all cases, the surety's liability is limited 
to the per-occurrence and annual aggregate penal sums.
    (d) The owner or operator who uses a surety bond to satisfy the 
requirements of Sec.  280.93 must establish a standby trust fund when 
the surety bond is acquired. Under the terms of the bond, all amounts 
paid by the surety under the bond will be deposited directly into the 
standby trust fund in accordance with instructions from the Director 
under Sec.  280.112. This standby trust fund must meet the requirements 
specified in Sec.  280.103.

Sec.  280.100  Use of state-required mechanism.

    (a) For underground storage tanks located in a state that does not 
have an approved program, and where the state requires owners or 
operators of underground storage tanks to demonstrate financial 
responsibility for taking corrective action and/or for compensating 
third parties for bodily injury and property damage, an owner or 
operator may use a state-required financial mechanism to meet the 
requirements of Sec.  280.93 if the Regional Administrator determines 
that the state mechanism is at least equivalent to the financial 
mechanisms specified in this subpart.
    (b) The Regional Administrator will evaluate the equivalency of a 
state-required mechanism principally in terms of: certainty of the 
availability of funds for taking corrective action and/or for 
compensating third parties; the amount of funds that will be made 
available; and the types of costs covered. The Regional Administrator 
may also consider other factors as is necessary.
    (c) The state, an owner or operator, or any other interested party 
may submit to the Regional Administrator a written petition requesting 
that one or more of the state-required mechanisms be considered 
acceptable for meeting the requirements of Sec.  280.93. The submission 
must include copies of the appropriate state statutory and regulatory 
requirements and must show the amount of funds for corrective action 
and/or for compensating third parties assured by the mechanism(s). The 
Regional Administrator may require the petitioner to submit additional 
information as is deemed necessary to make this determination.
    (d) Any petition under this section may be submitted on behalf of 
all of the state's underground storage tank owners and operators.
    (e) The Regional Administrator will notify the petitioner of his 
determination regarding the mechanism's acceptability in lieu of 
financial mechanisms specified in this

[[Page 41649]]

subpart. Pending this determination, the owners and operators using 
such mechanisms will be deemed to be in compliance with the 
requirements of Sec.  280.93 for underground storage tanks located in 
the state for the amounts and types of costs covered by such 
mechanisms.


Sec.  280.101  State fund or other state assurance.

    (a) An owner or operator may satisfy the requirements of Sec.  
280.93 for underground storage tanks located in a state, where EPA is 
administering the requirements of this subpart, which assures that 
monies will be available from a state fund or state assurance program 
to cover costs up to the limits specified in Sec.  280.93 or otherwise 
assures that such costs will be paid if the Regional Administrator 
determines that the state's assurance is at least equivalent to the 
financial mechanisms specified in this subpart.
    (b) The Regional Administrator will evaluate the equivalency of a 
state fund or other state assurance principally in terms of: Certainty 
of the availability of funds for taking corrective action and/or for 
compensating third parties; the amount of funds that will be made 
available; and the types of costs covered. The Regional Administrator 
may also consider other factors as is necessary.
    (c) The state must submit to the Regional Administrator a 
description of the state fund or other state assurance to be supplied 
as financial assurance, along with a list of the classes of underground 
storage tanks to which the funds may be applied. The Regional 
Administrator may require the state to submit additional information as 
is deemed necessary to make a determination regarding the acceptability 
of the state fund or other state assurance. Pending the determination 
by the Regional Administrator, the owner or operator of a covered class 
of USTs will be deemed to be in compliance with the requirements of 
Sec.  280.93 for the amounts and types of costs covered by the state 
fund or other state assurance.
    (d) The Regional Administrator will notify the state of his 
determination regarding the acceptability of the state's fund or other 
assurance in lieu of financial mechanisms specified in this subpart. 
Within 60 days after the Regional Administrator notifies a state that a 
state fund or other state assurance is acceptable, the state must 
provide to each owner or operator for which it is assuming financial 
responsibility a letter or certificate describing the nature of the 
state's assumption of responsibility. The letter or certificate from 
the state must include, or have attached to it, the following 
information: the facility's name and address and the amount of funds 
for corrective action and/or for compensating third parties that is 
assured by the state. The owner or operator must maintain this letter 
or certificate on file as proof of financial responsibility in 
accordance with Sec.  280.111(b)(8).


Sec.  280.102  Trust fund.

    (a) An owner or operator may satisfy the requirements of Sec.  
280.93 by establishing a trust fund that conforms to the requirements 
of this section. The trustee must be an entity that has the authority 
to act as a trustee and whose trust operations are regulated and 
examined by a federal agency or an agency of the state in which the 
fund is established.
    (b) The wording of the trust agreement must be identical to the 
wording specified in Sec.  280.103(b)(1), and must be accompanied by a 
formal certification of acknowledgement as specified in Sec.  
280.103(b)(2).
    (c) The trust fund, when established, must be funded for the full 
required amount of coverage, or funded for part of the required amount 
of coverage and used in combination with other mechanism(s) that 
provide the remaining required coverage.
    (d) If the value of the trust fund is greater than the required 
amount of coverage, the owner or operator may submit a written request 
to the Director of the implementing agency for release of the excess.
    (e) If other financial assurance as specified in this subpart is 
substituted for all or part of the trust fund, the owner or operator 
may submit a written request to the Director of the implementing agency 
for release of the excess.
    (f) Within 60 days after receiving a request from the owner or 
operator for release of funds as specified in paragraph (d) or (e) of 
this section, the Director of the implementing agency will instruct the 
trustee to release to the owner or operator such funds as the Director 
specifies in writing.


Sec.  280.103  Standby trust fund.

    (a) An owner or operator using any one of the mechanisms authorized 
by Sec. Sec.  280.96, 280.98, or 280.99 must establish a standby trust 
fund when the mechanism is acquired. The trustee of the standby trust 
fund must be an entity that has the authority to act as a trustee and 
whose trust operations are regulated and examined by a Federal agency 
or an agency of the state in which the fund is established.
    (b)(1) The standby trust agreement, or trust agreement, must be 
worded as follows, except that instructions in brackets are to be 
replaced with the relevant information and the brackets deleted:
Trust Agreement
    Trust agreement, the ``Agreement,'' entered into as of [date] by 
and between [name of the owner or operator], a [name of state] [insert 
``corporation,'' ``partnership,'' ``association,'' or 
``proprietorship''], the ``Grantor,'' and [name of corporate trustee], 
[insert ``Incorporated in the state of ___ '' or ``a national bank''], 
the ``Trustee.''
    Whereas, the United States Environmental Protection Agency, 
``EPA,'' an agency of the United States Government, has established 
certain regulations applicable to the Grantor, requiring that an owner 
or operator of an underground storage tank shall provide assurance that 
funds will be available when needed for corrective action and third-
party compensation for bodily injury and property damage caused by 
sudden and nonsudden accidental releases arising from the operation of 
the underground storage tank. The attached Schedule A lists the number 
of tanks at each facility and the name(s) and address(es) of the 
facility(ies) where the tanks are located that are covered by the 
[insert ``standby'' where trust agreement is standby trust agreement] 
trust agreement.
    [Whereas, the Grantor has elected to establish [insert either ``a 
guarantee,'' ``surety bond,'' or ``letter of credit''] to provide all 
or part of such financial assurance for the underground storage tanks 
identified herein and is required to establish a standby trust fund 
able to accept payments from the instrument (This paragraph is only 
applicable to the standby trust agreement.)];
    Whereas, the Grantor, acting through its duly authorized officers, 
has selected the Trustee to be the trustee under this agreement, and 
the Trustee is willing to act as trustee;
    Now, therefore, the Grantor and the Trustee agree as follows:
Section 1. Definitions
    As used in this Agreement:
    (a) The term ``Grantor'' means the owner or operator who enters 
into this Agreement and any successors or assigns of the Grantor.
    (b) The term ``Trustee'' means the Trustee who enters into this 
Agreement and any successor Trustee.

Section 2. Identification of the Financial Assurance Mechanism
    This Agreement pertains to the [identify the financial assurance 
mechanism, either a guarantee, surety bond, or letter of credit, from 
which the standby trust fund is established to receive payments (This 
paragraph is only applicable to the standby trust agreement.)].
Section 3. Establishment of Fund
    The Grantor and the Trustee hereby establish a trust fund, the 
``Fund,'' for the benefit of [implementing agency]. The Grantor and the 
Trustee intend that no third party have access to the Fund except as 
herein provided. [The Fund is established initially as a standby to 
receive payments and shall not consist of any property.] Payments made 
by the provider of financial assurance pursuant to [the Director of the 
implementing agency's] instruction are transferred to the Trustee and 
are referred to as the Fund, together with all earnings and profits 
thereon, less any payments or distributions made by the Trustee 
pursuant to this Agreement. The Fund shall be held by the Trustee, IN 
TRUST, as hereinafter provided. The Trustee shall not be responsible 
nor shall it undertake any responsibility for the amount or adequacy 
of, nor any duty to collect from the Grantor as provider of financial 
assurance, any payments necessary to discharge any liability of the 
Grantor established by [the state implementing agency]
Section 4. Payment for [``Corrective Action'' and/or ``Third-Party 
Liability Claims'']
    The Trustee shall make payments from the Fund as [the Director of 
the implementing agency] shall direct, in writing, to provide for the 
payment of the costs of [insert: ``taking corrective action'' and/or

    (c) The Director of the implementing agency will instruct the 
trustee to refund the balance of the standby trust fund to the provider 
of financial assurance if the Director determines that no additional 
corrective action costs or third-party liability claims will occur as a 
result of a release covered by the financial assurance mechanism for 
which the standby trust fund was established.
    (d) An owner or operator may establish one trust fund as the 
depository mechanism for all funds assured in compliance with this 
rule.


Sec.  280.104  Local government bond rating test.

    (a) A general purpose local government owner or operator and/or 
local government serving as a guarantor may satisfy the requirements of 
Sec.  280.93 by having a currently outstanding issue or issues of 
general obligation bonds of $1 million or more, excluding refunded 
obligations, with a Moody's rating of Aaa, Aa, A, or Baa, or a Standard 
& Poor's rating of AAA, AA, A, or BBB. Where a local government has 
multiple outstanding issues, or where a local government's bonds are 
rated by both Moody's and Standard and Poor's, the lowest rating must 
be used to determine eligibility. Bonds that are backed by credit 
enhancement other than municipal bond insurance may not be considered 
in determining the amount of applicable bonds outstanding.
    (b) A local government owner or operator or local government 
serving as a guarantor that is not a general-purpose local government 
and does not have the legal authority to issue general obligation bonds 
may satisfy the requirements of Sec.  280.93 by having a currently 
outstanding issue or issues of revenue bonds of $1 million or more, 
excluding refunded issues, and by also having a Moody's rating of Aaa, 
Aa, A, or Baa, or a Standard & Poor's rating of AAA, AA, A, or BBB as 
the lowest rating for any rated revenue bond issued by the local 
government. Where bonds are rated by both Moody's and Standard & 
Poor's, the lower rating for each bond must be used to determine 
eligibility. Bonds that are backed by credit enhancement may not be 
considered in determining the amount of applicable bonds outstanding.
    (c) The local government owner or operator and/or guarantor must 
maintain a copy of its bond rating published within the last 12 months 
by Moody's or Standard & Poor's.
    (d) To demonstrate that it meets the local government bond rating 
test, the chief financial officer of a general purpose local government 
owner or operator and/or guarantor must sign a letter worded exactly as 
follows, except that the instructions in brackets are to be replaced by 
the relevant information and the brackets deleted:
Letter from Chief Financial Officer
    I am the chief financial officer of [insert: name and address of 
local government owner or operator, or guarantor]. This letter is in

responsibility for [insert: ``taking corrective action'' and/or 
``compensating third parties for bodily injury and property damage''] 
caused by [insert: ``sudden accidental releases'' or ``nonsudden 
accidental releases'' or ``accidental releases''] in the amount of at 
least [insert: dollar amount] per occurrence and [insert: dollar 
amount] annual aggregate arising from operating (an) underground 
storage tank(s).
    Underground storage tanks at the following facilities are assured 
by this bond rating test: [List for each facility: the name and address 
of the facility where tanks are assured by the bond rating test].
    The details of the issue date, maturity, outstanding amount, bond 
rating, and bond rating agency of all outstanding bond issues that are

----------------------------------------------------------------------------------------------------------------

    The total outstanding obligation of [insert amount], excluding 
refunded bond issues, exceeds the minimum amount of $1 million. All 
outstanding general obligation bonds issued by this government that 
have been rated by Moody's or Standard & Poor's are rated as at least 
investment grade (Moody's Baa or Standard & Poor's BBB) based on the 
most recent ratings published within the last 12 months. Neither rating 
service has provided notification within the last 12 months of 
downgrading of bond ratings below investment grade or of withdrawal of 
bond rating other than for repayment of outstanding bond issues.
    I hereby certify that the wording of this letter is identical to 
the wording specified in 40 CFR 280.104(d) as such regulations were 
constituted on the date shown immediately below.

    The total outstanding obligation of [insert amount], excluding

are not backed by third-party credit enhancement or insured by a 
municipal bond insurance company. Neither rating service has provided 
notification within the last 12 months of downgrading of bond ratings 
below investment grade or of withdrawal of bond rating other than for

    (f) The Director of the implementing agency may require reports of 
financial condition at any time from the local government owner or 
operator, and/or local government guarantor. If the Director finds, on 
the basis of such reports or other information, that the local 
government owner or operator, and/or guarantor, no longer meets the 
local government bond rating test requirements of Sec.  280.104, the 
local government owner or operator must obtain alternative coverage 
within 30 days after notification of such a finding.
    (g) If a local government owner or operator using the bond rating 
test to provide financial assurance finds that it no longer meets the 
bond rating test requirements, the local government owner or operator 
must obtain alternative coverage within 150 days of the change in 
status.
    (h) If the local government owner or operator fails to obtain 
alternate assurance within 150 days of finding that it no longer meets 
the requirements of the bond rating test or within 30 days of 
notification by the Director of the implementing agency that it no 
longer meets the requirements of the bond rating test, the owner or 
operator must notify the Director of such failure within 10 days.

provide financial assurance finds that it no longer meets the 
requirements of the financial test based on the year-end financial 
statements, the owner or operator must obtain alternative coverage 
within 150 days of the end of the year for which financial statements 
have been prepared.
    (e) The Director of the implementing agency may require reports of 
financial condition at any time from the local government owner or 
operator. If the Director finds, on the basis of such reports or other 
information, that the local government owner or operator no longer 
meets the financial test requirements of Sec.  280.105(b) and (c), the 
owner or operator must obtain alternate coverage within 30 days after 
notification of such a finding.
    (f) If the local government owner or operator fails to obtain 
alternate assurance within 150 days of finding that it no longer meets 
the requirements of the financial test based on the year-end financial 
statements or within 30 days of notification by the Director of the 
implementing agency that it no longer meets the requirements of the 
financial test, the owner or operator must notify the Director of such 
failure within 10 days.


Sec.  280.106  Local government guarantee.

    (a) A local government owner or operator may satisfy the 
requirements of Sec.  280.93 by obtaining a guarantee that conforms to 
the requirements of this section. The guarantor must be either the 
state in which the local government owner or operator is located or a 
local government having a ``substantial governmental relationship'' 
with the owner and operator and issuing the guarantee as an act 
incident to that relationship. A local government acting as the 
guarantor must:
    (1) Demonstrate that it meets the bond rating test requirement of 
Sec.  280.104 and deliver a copy of the chief financial officer's 
letter as contained in Sec.  280.104(d) and (e) to the local government 
owner or operator; or
    (2) Demonstrate that it meets the worksheet test requirements of 
Sec.  280.105 and deliver a copy of the chief financial officer's 
letter as contained in Sec.  280.105(c) to the local government owner 
or operator; or
    (3) Demonstrate that it meets the local government fund 
requirements of Sec.  280.107(a), (b), or (c) and deliver a copy of the 
chief financial officer's letter as contained in Sec.  280.107 to the 
local government owner or operator.
    (b) If the local government guarantor is unable to demonstrate 
financial assurance under any of Sec. Sec.  280.104, 280.105, or 
280.107(a), (b), or (c), at the end of the financial reporting year, 
the guarantor shall send by certified mail, before cancellation or non-
renewal of the guarantee, notice to the owner or operator. The 
guarantee will terminate no less than 120 days after the date the owner 
or operator receives the notification, as evidenced by the return 
receipt. The owner or operator must obtain alternative coverage as 
specified in Sec.  280.114(e).
    (c) The guarantee agreement must be worded as specified in 
paragraph (d) or (e) of this section, depending on which of the 
following alternative guarantee arrangements is selected:
    (1) If, in the default or incapacity of the owner or operator, the 
guarantor guarantees to fund a standby trust as directed by the 
Director of the implementing agency, the guarantee shall be worded as 
specified in paragraph (d) of this section.
    (2) If, in the default or incapacity of the owner or operator, the 
guarantor guarantees to make payments as directed by the Director of 
the implementing agency for taking corrective action or compensating 
third parties for bodily injury and property damage, the guarantee 
shall be worded as specified in paragraph (e) of this section.
    (d) If the guarantor is a state, the local government guarantee 
with standby trust must be worded exactly as follows, except that 
instructions in brackets are to be replaced with relevant information 
and the brackets deleted:

releases arising from the operation of the above-identified tank(s), or 
fails to pay an amount agreed to in settlement of a claim arising from

guarantee by [the implementing agency], by any or all third parties, or

Sec.  280.107  Local government fund.

    A local government owner or operator may satisfy the requirements 
of Sec.  280.93 by establishing a dedicated fund account that conforms 
to the requirements of this section. Except as specified in paragraph 
(b) of this section, a dedicated fund may not be commingled with other 
funds or otherwise used in normal operations. A dedicated fund will be 
considered eligible if it meets one of the following requirements:
    (a) The fund is dedicated by state constitutional provision, or 
local government statute, charter, ordinance, or order to pay for 
taking corrective action and for compensating third parties for bodily 
injury and property damage caused by accidental releases arising from 
the operation of petroleum underground storage tanks and is funded for 
the full amount of coverage required under Sec.  280.93, or funded for 
part of the required amount of coverage and used in combination with 
other mechanism(s) that provide the remaining coverage; or
    (b) The fund is dedicated by state constitutional provision, or 
local government statute, charter, ordinance, or order as a contingency 
fund for general emergencies, including taking corrective action and 
compensating third parties for bodily injury and property damage caused 
by accidental releases arising from the operation of petroleum 
underground storage tanks, and is funded for five times the full amount 
of coverage required under Sec.  280.93, or funded for part of the 
required amount of coverage and used in combination with other 
mechanism(s) that provide the remaining coverage. If the fund is funded 
for less than five times the amount of coverage required under Sec.  
280.93, the amount of financial responsibility demonstrated by the fund 
may not exceed one-fifth the amount in the fund; or
    (c) The fund is dedicated by state constitutional provision, or 
local government statute, charter, ordinance or order to pay for taking 
corrective action and for compensating third parties for bodily injury 
and property damage caused by accidental releases arising from the 
operation of petroleum underground storage tanks. A payment is made to 
the fund once every year for seven years until the fund is fully-
funded. This seven year period is hereafter referred to as the ``pay-
in-period.'' The amount of each payment must be determined by this 
formula:
[GRAPHIC] [TIFF OMITTED] TR15JY15.042


Where TF is the total required financial assurance for the owner or 
operator, CF is the current amount in the fund, and Y is the number of 
years remaining in the pay-in-period; and,
    (1) The local government owner or operator has available bonding 
authority, approved through voter referendum (if such approval is 
necessary prior to the issuance of bonds), for an amount equal to the 
difference between the required amount of coverage and the amount held 
in the dedicated fund. This bonding authority shall be available for 
taking corrective action and for compensating third parties for bodily 
injury and property damage caused by accidental releases arising from 
the operation of petroleum underground storage tanks; or
    (2) The local government owner or operator has a letter signed by 
the appropriate state attorney general stating that the use of the 
bonding authority will not increase the local government's debt beyond 
the legal debt ceilings established by the relevant state laws. The 
letter must also state that prior voter approval is not necessary 
before use of the bonding authority.
    (d) To demonstrate that it meets the requirements of the local 
government fund, the chief financial officer of the local government 
owner or operator and/or guarantor must sign a letter worded exactly as 
follows, except that the instructions in brackets are to be replaced by 
the relevant information and the brackets deleted:

     Letter from Chief Financial Officer
    I am the chief financial officer of [insert: name and address of

action'' and/or ``compensating third parties for bodily injury and 
property damage''] caused by [insert: ``sudden accidental releases'' or 
``nonsudden accidental releases'' or ``accidental releases''] in the 
amount of at least [insert: dollar amount] per occurrence and [insert: 
dollar amount] annual aggregate arising from operating (an) underground 
storage tank(s).
    Underground storage tanks at the following facilities are assured 
by this local government fund mechanism: [List for each facility: The

government fund is funded for five times the full amount of coverage 
required under Sec.  280.93, or funded for part of the required amount 
of coverage and used in combination with other mechanisms(s) that 
provide the remaining coverage,'' or ``A payment is made to the fund 
once every year for seven years until the fund is fully-funded and 
[name of local government owner or operator] has available bonding 
authority, approved through voter referendum, of an amount equal to the 
difference between the required amount of coverage and the amount held 
in the dedicated fund'' or ``A payment is made to the fund once every

and (2) that prior voter approval is not necessary before use of the 
bonding authority''].

Sec.  280.112  Drawing on financial assurance mechanisms.

    (a) Except as specified in paragraph (d) of this section, the 
Director of the implementing agency shall require the guarantor, 
surety, or institution issuing a letter of credit to place the amount 
of funds stipulated by the Director, up to the limit of funds provided 
by the financial assurance mechanism, into the standby trust if:
    (1)(i) The owner or operator fails to establish alternate financial 
assurance within 60 days after receiving notice of cancellation of the 
guarantee, surety bond, letter of credit, or, as applicable, other 
financial assurance mechanism; and
    (ii) The Director determines or suspects that a release from an 
underground storage tank covered by the mechanism has occurred and so 
notifies the owner or operator or the owner or operator has notified 
the Director pursuant to subparts E or F of a release from an 
underground storage tank covered by the mechanism; or
    (2) The conditions of paragraph (b)(1) or (b)(2)(i) or (ii) of this 
section are satisfied.
    (b) The Director of the implementing agency may draw on a standby 
trust fund when:
    (1) The Director makes a final determination that a release has 
occurred and immediate or long-term corrective action for the release 
is needed, and the owner or operator, after appropriate notice and 
opportunity to comply, has not conducted corrective action as required 
under subpart F of this part; or
    (2) The Director has received either:
    (i) Certification from the owner or operator and the third-party 
liability claimant(s) and from attorneys representing the owner or 
operator and the third-party liability claimant(s) that a third-party 
liability claim should be paid. The certification must be worded as

the owner or operator has not satisfied the judgment.
    (c) If the Director of the implementing agency determines that the 
amount of corrective action costs and third-party liability claims 
eligible for payment under paragraph (b) of this section may exceed the 
balance of the standby trust fund and the obligation of the provider of 
financial assurance, the first priority for payment shall be corrective 
action costs necessary to protect human health and the environment. The 
Director shall pay third-party liability claims in the order in which 
the Director receives certifications under paragraph (b)(2)(i) of this 
section, and valid court orders under paragraph (b)(2)(ii) of this

    An owner or operator is no longer required to maintain financial 
responsibility under this subpart for an underground storage tank after

commencement and submit the appropriate forms listed in Sec.  
280.111(b) documenting current financial responsibility.
    (b) Within 10 days after commencement of a voluntary or involuntary

providing financial assurance as debtor, such guarantor must notify the 
owner or operator by certified mail of such commencement as required 
under the terms of the guarantee specified in Sec.  280.96.
    (c) Within 10 days after commencement of a voluntary or involuntary 
proceeding under Title 11 (Bankruptcy), U.S. Code, naming a local 
government owner or operator as debtor, the local government owner or 
operator must notify the Director of the implementing agency by 
certified mail of such commencement and submit the appropriate forms

notify the Director of the implementing agency.
    (f) Within 30 days after receipt of notification that a state fund 
or other state assurance has become incapable of paying for assured

which the funds were drawn:
    (1) Replenish the value of financial assurance to equal the full 
amount of coverage required; or

which funds in the standby trust have been reduced.
    (b) For purposes of this section, the full amount of coverage 
required is the amount of coverage to be provided by Sec.  280.93. If a 
combination of mechanisms was used to provide the assurance funds which 
were drawn upon, replenishment shall occur by the earliest anniversary 
date among the mechanisms.


Sec.  280.116  Suspension of enforcement. [Reserved]

Subpart I--Lender Liability


Sec.  280.200  Definitions.

    (a) UST technical standards, as used in this subpart, refers to the 
UST preventative and operating requirements under subparts B, C, D, G, 
J, and K of this part and Sec.  280.50.
    (b) Petroleum production, refining, and marketing. (1) Petroleum 
production means the production of crude oil or other forms of 
petroleum (as defined in Sec.  280.12) as well as the production of 
petroleum products from purchased materials.
    (2) Petroleum refining means the cracking, distillation, 
separation, conversion, upgrading, and finishing of refined petroleum 
or petroleum products.
    (3) Petroleum marketing means the distribution, transfer, or sale 
of petroleum or petroleum products for wholesale or retail purposes.
    (c) Indicia of ownership means evidence of a secured interest, 
evidence of an interest in a security interest, or evidence of an 
interest in real or personal property securing a loan or other 
obligation, including any legal or equitable title or deed to real or 
personal property acquired through or incident to foreclosure. Evidence 
of such interests include, but are not limited to, mortgages, deeds of 
trust, liens, surety bonds and guarantees of obligations, title held 
pursuant to a lease financing transaction in which the lessor does not 
select initially the leased property (hereinafter ``lease financing 
transaction''), and legal or equitable title obtained pursuant to 
foreclosure. Evidence of such interests also includes assignments, 
pledges, or other rights to or other forms of encumbrance against 
property that are held primarily to protect a security interest. A 
person is not required to hold title or a security interest in order to 
maintain indicia of ownership.
    (d) A holder is a person who, upon the effective date of this 
regulation or in the future, maintains indicia of ownership (as defined 
in Sec.  280.200(c)) primarily to protect a security interest (as 
defined in Sec.  280.200(f)(1)) in a petroleum UST or UST system or 
facility or property on which a petroleum UST or UST system is located. 
A holder includes the initial holder (such as a loan originator); any 
subsequent holder (such as a successor-in-interest or subsequent 
purchaser of the security interest on the secondary market); a 
guarantor of an obligation, surety, or any other person who holds 
ownership indicia primarily to protect a security interest; or a 
receiver or other person who acts on behalf or for the benefit of a 
holder.
    (e) A borrower, debtor, or obligor is a person whose UST or UST 
system or facility or property on which the UST or UST system is 
located is encumbered by a security interest. These terms may be used 
interchangeably.
    (f) Primarily to protect a security interest means that the 
holder's indicia of ownership are held primarily for the purpose of 
securing payment or performance of an obligation.
    (1) Security interest means an interest in a petroleum UST or UST 
system or in the facility or property on which a petroleum UST or UST 
system is located, created or established for the purpose of securing a 
loan or other obligation. Security interests include but are not 
limited to mortgages, deeds of trusts, liens, and title pursuant to 
lease financing transactions. Security interests may also arise from 
transactions such as sale and leasebacks, conditional sales, 
installment sales, trust receipt transactions, certain assignments, 
factoring agreements, accounts receivable financing arrangements, and 
consignments, if the transaction creates or establishes an interest in 
an UST or UST system or in the facility or property on which the UST or 
UST system is located, for the

[[Page 41663]]

purpose of securing a loan or other obligation.
    (2) Primarily to protect a security interest, as used in this 
subpart, does not include indicia of ownership held primarily for 
investment purposes, nor ownership indicia held primarily for purposes 
other than as protection for a security interest. A holder may have 
other, secondary reasons for maintaining indicia of ownership, but the 
primary reason why any ownership indicia are held must be as protection 
for a security interest.
    (g) Operation means, for purposes of this subpart, the use, 
storage, filling, or dispensing of petroleum contained in an UST or UST 
system.


Sec.  280.210  Participation in management.

    The term ``participating in the management of an UST or UST 
system'' means that, subsequent to the effective date of this subpart, 
December 6, 1995, the holder is engaging in decisionmaking control of, 
or activities related to, operation of the UST or UST system, as 
defined herein.
    (a) Actions that are participation in management. (1) Participation 
in the management of an UST or UST system means, for purposes of this 
subpart, actual participation by the holder in the management or 
control of decisionmaking related to the operation of an UST or UST 
system. Participation in management does not include the mere capacity 
or ability to influence or the unexercised right to control UST or UST 
system operations. A holder is participating in the management of the 
UST or UST system only if the holder either:
    (i) Exercises decisionmaking control over the operational (as 
opposed to financial or administrative) aspects of the UST or UST 
system, such that the holder has undertaken responsibility for all or 
substantially all of the management of the UST or UST system; or
    (ii) Exercises control at a level comparable to that of a manager 
of the borrower's enterprise, such that the holder has assumed or 
manifested responsibility for the overall management of the enterprise 
encompassing the day-to-day decisionmaking of the enterprise with 
respect to all, or substantially all, of the operational (as opposed to 
financial or administrative) aspects of the enterprise.
    (2) Operational aspects of the enterprise relate to the use, 
storage, filling, or dispensing of petroleum contained in an UST or UST 
system, and include functions such as that of a facility or plant 
manager, operations manager, chief operating officer, or chief 
executive officer. Financial or administrative aspects include 
functions such as that of a credit manager, accounts payable/receivable 
manager, personnel manager, controller, chief financial officer, or 
similar functions. Operational aspects of the enterprise do not include 
the financial or administrative aspects of the enterprise, or actions 
associated with environmental compliance, or actions undertaken 
voluntarily to protect the environment in accordance with applicable 
requirements in this part or applicable state requirements in those 
states that have been delegated authority by EPA to administer the UST 
program pursuant to 42 U.S.C. 6991c and 40 CFR part 281.
    (b) Actions that are not participation in management pre-
foreclosure. (1) Actions at the inception of the loan or other 
transaction. No act or omission prior to the time that indicia of 
ownership are held primarily to protect a security interest constitutes 
evidence of participation in management within the meaning of this 
subpart. A prospective holder who undertakes or requires an 
environmental investigation (which could include a site assessment, 
inspection, and/or audit) of the UST or UST system or facility or 
property on which the UST or UST system is located (in which indicia of 
ownership are to be held), or requires a prospective borrower to clean 
up contamination from the UST or UST system or to comply or come into 
compliance (whether prior or subsequent to the time that indicia of 
ownership are held primarily to protect a security interest) with any 
applicable law or regulation, is not by such action considered to be 
participating in the management of the UST or UST system or facility or 
property on which the UST or UST system is located.
    (2) Loan policing and work out. Actions that are consistent with 
holding ownership indicia primarily to protect a security interest do 
not constitute participation in management for purposes of this 
subpart. The authority for the holder to take such actions may, but 
need not, be contained in contractual or other documents specifying 
requirements for financial, environmental, and other warranties, 
covenants, conditions, representations or promises from the borrower. 
Loan policing and work out activities cover and include all such 
activities up to foreclosure, exclusive of any activities that 
constitute participation in management.
    (i) Policing the security interest or loan. (A) A holder who 
engages in policing activities prior to foreclosure will remain within 
the exemption provided that the holder does not together with other 
actions participate in the management of the UST or UST system as 
provided in Sec.  280.210(a). Such policing actions include, but are 
not limited to, requiring the borrower to clean up contamination from 
the UST or UST system during the term of the security interest; 
requiring the borrower to comply or come into compliance with 
applicable federal, state, and local environmental and other laws, 
rules, and regulations during the term of the security interest; 
securing or exercising authority to monitor or inspect the UST or UST 
system or facility or property on which the UST or UST system is 
located (including on-site inspections) in which indicia of ownership 
are maintained, or the borrower's business or financial condition 
during the term of the security interest; or taking other actions to 
adequately police the loan or security interest (such as requiring a 
borrower to comply with any warranties, covenants, conditions, 
representations, or promises from the borrower).
    (B) Policing activities also include undertaking by the holder of 
UST environmental compliance actions and voluntary environmental 
actions taken in compliance with this part, provided that the holder 
does not otherwise participate in the management or daily operation of 
the UST or UST system as provided in Sec.  280.210(a) and Sec.  
280.230. Such allowable actions include, but are not limited to, 
release detection and release reporting, release response and 
corrective action, temporary or permanent closure of an UST or UST 
system, UST upgrading or replacement, and maintenance of corrosion 
protection. A holder who undertakes these actions must do so in 
compliance with the applicable requirements in this part or applicable 
state requirements in those states that have been delegated authority 
by EPA to administer the UST program pursuant to 42 U.S.C. 6991c and 40 
CFR part 281. A holder may directly oversee these environmental 
compliance actions and voluntary environmental actions, and directly 
hire contractors to perform the work, and is not by such action 
considered to be participating in the management of the UST or UST 
system.
    (ii) Loan work out. A holder who engages in work out activities 
prior to foreclosure will remain within the exemption provided that the 
holder does not together with other actions participate in the 
management of the UST or UST system as provided in Sec.  280.210(a). 
For purposes of this rule, ``work out'' refers to those actions by 
which a holder, at any time prior to

[[Page 41664]]

foreclosure, seeks to prevent, cure, or mitigate a default by the 
borrower or obligor; or to preserve, or prevent the diminution of, the 
value of the security. Work out activities include, but are not limited 
to, restructuring or renegotiating the terms of the security interest; 
requiring payment of additional rent or interest; exercising 
forbearance; requiring or exercising rights pursuant to an assignment 
of accounts or other amounts owing to an obligor; requiring or 
exercising rights pursuant to an escrow agreement pertaining to amounts 
owing to an obligor; providing specific or general financial or other 
advice, suggestions, counseling, or guidance; and exercising any right 
or remedy the holder is entitled to by law or under any warranties, 
covenants, conditions, representations, or promises from the borrower.
    (c) Foreclosure on an UST or UST system or facility or property on 
which an UST or UST system is located, and participation in management 
activities post-foreclosure.
    (1) Foreclosure. (i) Indicia of ownership that are held primarily 
to protect a security interest include legal or equitable title or deed 
to real or personal property acquired through or incident to 
foreclosure. For purposes of this subpart, the term ``foreclosure'' 
means that legal, marketable or equitable title or deed has been 
issued, approved, and recorded, and that the holder has obtained access 
to the UST, UST system, UST facility, and property on which the UST or 
UST system is located, provided that the holder acted diligently to 
acquire marketable title or deed and to gain access to the UST, UST 
system, UST facility, and property on which the UST or UST system is 
located. The indicia of ownership held after foreclosure continue to be 
maintained primarily as protection for a security interest provided 
that the holder undertakes to sell, re-lease an UST or UST system or 
facility or property on which the UST or UST system is located, held 
pursuant to a lease financing transaction (whether by a new lease 
financing transaction or substitution of the lessee), or otherwise 
divest itself of the UST or UST system or facility or property on which 
the UST or UST system is located, in a reasonably expeditious manner, 
using whatever commercially reasonable means are relevant or 
appropriate with respect to the UST or UST system or facility or 
property on which the UST or UST system is located, taking all facts 
and circumstances into consideration, and provided that the holder does 
not participate in management (as defined in Sec.  280.210(a)) prior to 
or after foreclosure.
    (ii) For purposes of establishing that a holder is seeking to sell, 
re-lease pursuant to a lease financing transaction (whether by a new 
lease financing transaction or substitution of the lessee), or divest 
in a reasonably expeditious manner an UST or UST system or facility or 
property on which the UST or UST system is located, the holder may use 
whatever commercially reasonable means as are relevant or appropriate 
with respect to the UST or UST system or facility or property on which 
the UST or UST system is located, or may employ the means specified in 
Sec.  280.210(c)(2). A holder that outbids, rejects, or fails to act 
upon a written bona fide, firm offer of fair consideration for the UST 
or UST system or facility or property on which the UST or UST system is 
located, as provided in Sec.  280.210(c)(2), is not considered to hold 
indicia of ownership primarily to protect a security interest.
    (2) Holding foreclosed property for disposition and liquidation. A 
holder, who does not participate in management prior to or after 
foreclosure, may sell, re-lease, pursuant to a lease financing 
transaction (whether by a new lease financing transaction or 
substitution of the lessee), an UST or UST system or facility or 
property on which the UST or UST system is located, liquidate, wind up 
operations, and take measures, prior to sale or other disposition, to 
preserve, protect, or prepare the secured UST or UST system or facility 
or property on which the UST or UST system is located. A holder may 
also arrange for an existing or new operator to continue or initiate 
operation of the UST or UST system. The holder may conduct these 
activities without voiding the security interest exemption, subject to 
the requirements of this subpart.
    (i) A holder establishes that the ownership indicia maintained 
after foreclosure continue to be held primarily to protect a security 
interest by, within 12 months following foreclosure, listing the UST or 
UST system or the facility or property on which the UST or UST system 
is located, with a broker, dealer, or agent who deals with the type of 
property in question, or by advertising the UST or UST system or 
facility or property on which the UST or UST system is located, as 
being for sale or disposition on at least a monthly basis in either a 
real estate publication or a trade or other publication suitable for 
the UST or UST system or facility or property on which the UST or UST 
system is located, or a newspaper of general circulation (defined as 
one with a circulation over 10,000, or one suitable under any 
applicable federal, state, or local rules of court for publication 
required by court order or rules of civil procedure) covering the 
location of the UST or UST system or facility or property on which the 
UST or UST system is located. For purposes of this provision, the 12-
month period begins to run from December 6, 1995 or from the date that 
the marketable title or deed has been issued, approved and recorded, 
and the holder has obtained access to the UST, UST system, UST facility 
and property on which the UST or UST system is located, whichever is 
later, provided that the holder acted diligently to acquire marketable 
title or deed and to obtain access to the UST, UST system, UST facility 
and property on which the UST or UST system is located. If the holder 
fails to act diligently to acquire marketable title or deed or to gain 
access to the UST or UST system, the 12-month period begins to run from 
December 6, 1995 or from the date on which the holder first acquires 
either title to or possession of the secured UST or UST system, or 
facility or property on which the UST or UST system is located, 
whichever is later.
    (ii) A holder that outbids, rejects, or fails to act upon an offer 
of fair consideration for the UST or UST system or the facility or 
property on which the UST or UST system is located, establishes by such 
outbidding, rejection, or failure to act, that the ownership indicia in 
the secured UST or UST system or facility or property on which the UST 
or UST system is located are not held primarily to protect the security 
interest, unless the holder is required, in order to avoid liability 
under federal or state law, to make a higher bid, to obtain a higher 
offer, or to seek or obtain an offer in a different manner.
    (A) Fair consideration, in the case of a holder maintaining indicia 
of ownership primarily to protect a senior security interest in the UST 
or UST system or facility or property on which the UST or UST system is 
located, is the value of the security interest as defined in this 
section. The value of the security interest includes all debt and costs 
incurred by the security interest holder, and is calculated as an 
amount equal to or in excess of the sum of the outstanding principal 
(or comparable amount in the case of a lease that constitutes a 
security interest) owed to the holder immediately preceding the 
acquisition of full title (or possession in the case of a lease 
financing transaction) pursuant to foreclosure, plus any unpaid 
interest, rent, or penalties

[[Page 41665]]

(whether arising before or after foreclosure). The value of the 
security interest also includes all reasonable and necessary costs, 
fees, or other charges incurred by the holder incident to work out, 
foreclosure, retention, preserving, protecting, and preparing, prior to 
sale, the UST or UST system or facility or property on which the UST or 
UST system is located, re-lease, pursuant to a lease financing 
transaction (whether by a new lease financing transaction or 
substitution of the lessee), of an UST or UST system or facility or 
property on which the UST or UST system is located, or other 
disposition. The value of the security interest also includes 
environmental investigation costs (which could include a site 
assessment, inspection, and/or audit of the UST or UST system or 
facility or property on which the UST or UST system is located), and 
corrective action costs incurred under Sec. Sec.  280.51 through 280.67 
or any other costs incurred as a result of reasonable efforts to comply 
with any other applicable federal, state or local law or regulation; 
less any amounts received by the holder in connection with any partial 
disposition of the property and any amounts paid by the borrower (if 
not already applied to the borrower's obligations) subsequent to the 
acquisition of full title (or possession in the case of a lease 
financing transaction) pursuant to foreclosure. In the case of a holder 
maintaining indicia of ownership primarily to protect a junior security 
interest, fair consideration is the value of all outstanding higher 
priority security interests plus the value of the security interest 
held by the junior holder, each calculated as set forth in this 
paragraph (c).
    (B) Outbids, rejects, or fails to act upon an offer of fair 
consideration means that the holder outbids, rejects, or fails to act 
upon within 90 days of receipt, a written, bona fide, firm offer of 
fair consideration for the UST or UST system or facility or property on 
which the UST or UST system is located received at any time after six 
months following foreclosure, as defined in Sec.  280.210(c). A 
``written, bona fide, firm offer'' means a legally enforceable, 
commercially reasonable, cash offer solely for the foreclosed UST or 
UST system or facility or property on which the UST or UST system is 
located, including all material terms of the transaction, from a ready, 
willing, and able purchaser who demonstrates to the holder's 
satisfaction the ability to perform. For purposes of this provision, 
the six-month period begins to run from December 6, 1995 or from the 
date that marketable title or deed has been issued, approved and 
recorded to the holder, and the holder has obtained access to the UST, 
UST system, UST facility and property on which the UST or UST system is 
located, whichever is later, provided that the holder was acting 
diligently to acquire marketable title or deed and to obtain access to 
the UST or UST system, UST facility and property on which the UST or 
UST system is located. If the holder fails to act diligently to acquire 
marketable title or deed or to gain access to the UST or UST system, 
the six-month period begins to run from December 6, 1995 or from the 
date on which the holder first acquires either title to or possession 
of the secured UST or UST system, or facility or property on which the 
UST or UST system is located, whichever is later.
    (3) Actions that are not participation in management post-
foreclosure. A holder is not considered to be participating in the 
management of an UST or UST system or facility or property on which the 
UST or UST system is located when undertaking actions under this part, 
provided that the holder does not otherwise participate in the 
management or daily operation of the UST or UST system as provided in 
Sec.  280.210(a) and Sec.  280.230. Such allowable actions include, but 
are not limited to, release detection and release reporting, release 
response and corrective action, temporary or permanent closure of an 
UST or UST system, UST upgrading or replacement, and maintenance of 
corrosion protection. A holder who undertakes these actions must do so 
in compliance with the applicable requirements in this part or 
applicable state requirements in those states that have been delegated 
authority by EPA to administer the UST program pursuant to 42 U.S.C. 
6991c and 40 CFR part 281. A holder may directly oversee these 
environmental compliance actions and voluntary environmental actions, 
and directly hire contractors to perform the work, and is not by such 
action considered to be participating in the management of the UST or 
UST system.


Sec.  280.220  Ownership of an underground storage tank or underground 
storage tank system or facility or property on which an underground 
storage tank or underground storage tank system is located.

    Ownership of an UST or UST system or facility or property on which 
an UST or UST system is located. A holder is not an ``owner'' of a 
petroleum UST or UST system or facility or property on which a 
petroleum UST or UST system is located for purposes of compliance with 
the UST technical standards as defined in Sec.  280.200(a), the UST 
corrective action requirements under Sec. Sec.  280.51 through 280.67, 
and the UST financial responsibility requirements under Sec. Sec.  
280.90 through 280.111, provided the person:
    (a) Does not participate in the management of the UST or UST system 
as defined in Sec.  280.210; and
    (b) Does not engage in petroleum production, refining, and 
marketing as defined in Sec.  280.200(b).


Sec.  280.230  Operating an underground storage tank or underground 
storage tank system.

    (a) Operating an UST or UST system prior to foreclosure. A holder, 
prior to foreclosure, as defined in Sec.  280.210(c), is not an 
``operator'' of a petroleum UST or UST system for purposes of 
compliance with the UST technical standards as defined in Sec.  
280.200(a), the UST corrective action requirements under Sec. Sec.  
280.51 through 280.67, and the UST financial responsibility 
requirements under Sec. Sec.  280.90 through 280.111, provided that, 
after December 6, 1995, the holder is not in control of or does not 
have responsibility for the daily operation of the UST or UST system.
    (b) Operating an UST or UST system after foreclosure. The following 
provisions apply to a holder who, through foreclosure, as defined in 
Sec.  280.210(c), acquires a petroleum UST or UST system or facility or 
property on which a petroleum UST or UST system is located.
    (1) A holder is not an ``operator'' of a petroleum UST or UST 
system for purposes of compliance with this part if there is an 
operator, other than the holder, who is in control of or has 
responsibility for the daily operation of the UST or UST system, and 
who can be held responsible for compliance with applicable requirements 
of this part or applicable state requirements in those states that have 
been delegated authority by EPA to administer the UST program pursuant 
to 42 U.S.C. 6991c and 40 CFR part 281.
    (2) If another operator does not exist, as provided for under 
paragraph (b)(1) of this section, a holder is not an ``operator'' of 
the UST or UST system, for purposes of compliance with the UST 
technical standards as defined in Sec.  280.200(a), the UST corrective 
action requirements under Sec. Sec.  280.51 through 280.67, and the UST 
financial responsibility requirements under Sec. Sec.  280.90 through 
280.111, provided that the holder:
    (i) Empties all of its known USTs and UST systems within 60 
calendar days

[[Page 41666]]

after foreclosure or within 60 calendar days after December 6, 1995, 
whichever is later, or another reasonable time period specified by the 
implementing agency, so that no more than 2.5 centimeters (one inch) of 
residue, or 0.3 percent by weight of the total capacity of the UST 
system, remains in the system; leaves vent lines open and functioning; 
and caps and secures all other lines, pumps, manways, and ancillary 
equipment; and
    (ii) Empties those USTs and UST systems that are discovered after 
foreclosure within 60 calendar days after discovery or within 60 
calendar days after December 6, 1995, whichever is later, or another 
reasonable time period specified by the implementing agency, so that no 
more than 2.5 centimeters (one inch) of residue, or 0.3 percent by 
weight of the total capacity of the UST system, remains in the system; 
leaves vent lines open and functioning; and caps and secures all other 
lines, pumps, manways, and ancillary equipment.
    (3) If another operator does not exist, as provided for under 
paragraph (b)(1) of this section, in addition to satisfying the 
conditions under paragraph (b)(2) of this section, the holder must 
either:
    (i) Permanently close the UST or UST system in accordance with 
Sec. Sec.  280.71 through 280.74, except Sec.  280.72(b); or
    (ii) Temporarily close the UST or UST system in accordance with the 
following applicable provisions of Sec.  280.70:
    (A) Continue operation and maintenance of corrosion protection in 
accordance with Sec.  280.31;
    (B) Report suspected releases to the implementing agency; and
    (C) Conduct a site assessment in accordance with Sec.  280.72(a) if 
the UST system is temporarily closed for more than 12 months and the 
UST system does not meet either the performance standards in Sec.  
280.20 for new UST systems or the upgrading requirements in Sec.  
280.21, except that the spill and overfill equipment requirements do 
not have to be met. The holder must report any suspected releases to 
the implementing agency. For purposes of this provision, the 12-month 
period begins to run from December 6, 1995 or from the date on which 
the UST system is emptied and secured under paragraph (b)(2) of this 
section, whichever is later.
    (4) The UST system can remain in temporary closure until a 
subsequent purchaser has acquired marketable title to the UST or UST 
system or facility or property on which the UST or UST system is 
located. Once a subsequent purchaser acquires marketable title to the 
UST or UST system or facility or property on which the UST or UST 
system is located, the purchaser must decide whether to operate or 
close the UST or UST system in accordance with applicable requirements 
in this part or applicable state requirements in those states that have 
been delegated authority by EPA to administer the UST program pursuant 
to 42 U.S.C. 6991c and 40 CFR part 281.

Subpart K--UST Systems with Field-Constructed Tanks and Airport 
Hydrant Fuel Distribution Systems


Sec.  280.250  Definitions.

    For purposes of this subpart, the following definitions apply:
    Airport hydrant fuel distribution system (also called airport 
hydrant system) means an UST system which fuels aircraft and operates 
under high pressure with large diameter piping that typically 
terminates into one or more hydrants (fill stands). The airport hydrant 
system begins where fuel enters one or more tanks from an external 
source such as a pipeline, barge, rail car, or other motor fuel 
carrier.
    Field-constructed tank means a tank constructed in the field. For 
example, a tank constructed of concrete that is poured in the field, or 
a steel or fiberglass tank primarily fabricated in the field is 
considered field-constructed.


Sec.  280.251  General requirements.

    (a) Implementation of requirements. Owners and operators must 
comply with the requirements of this part for UST systems with field-
constructed tanks and airport hydrant systems as follows:
    (1) For UST systems installed on or before October 13, 2015 the

6991(k).

Subpart A--Purpose, General Requirements and Scope


Sec.  281.10  Purpose.

    (a) This part specifies the requirements that state programs must 
meet for approval by the Administrator under section 9004 of the Solid 
Waste Disposal Act, and the procedures EPA will follow in approving, 
revising and withdrawing approval of state programs.
    (b) State submissions for program approval must be in accordance 
with the procedures set out in this part.
    (c) A state may apply for approval under this part at any time 
after the promulgation of release detection, prevention, and corrective 
action regulations under Sec.  9003 of the Solid Waste Disposal Act.
    (d) Any state program approved by the Administrator under this part 
shall at all times be conducted in accordance with the requirements of 
this part.


Sec.  281.11  General requirements.

    (a) State program elements. The following substantive elements of a 
state program must be addressed in a state application for approval:
    (1) Requirements for all existing and new underground storage 
tanks:
    (i) New UST systems (design, construction, installation, and 
notification);
    (ii) Upgrading of existing UST systems;
    (iii) General operating requirements;
    (iv) Release detection;
    (v) Release reporting, investigation, and confirmation;
    (vi) Out-of-service USTs and closure;
    (vii) Release response and corrective action;
    (viii) Financial responsibility for UST systems containing 
petroleum; and
    (ix) Operator training.
    (2) Provisions for adequate enforcement of compliance with the 
above program elements.
    (b) Final approval. The state must demonstrate that its 
requirements under each state program element for existing and new UST 
systems are no less stringent than the corresponding federal 
requirements as set forth in subpart C of this part. The state must 
also demonstrate that it has a program that provides adequate 
enforcement of compliance with these requirements.
    (c) States with programs approved under this part are authorized to 
administer the state program in lieu of the federal program and will 
have primary enforcement responsibility with respect to the 
requirements of the approved program. EPA retains authority to take 
enforcement action in approved states as necessary and will notify the 
designated lead state agency of any such intended action.


Sec.  281.12  Scope and definitions.

    (a) Scope. (1) The Administrator may approve either partial or 
complete state programs. A ``partial'' state program regulates either 
solely UST systems containing petroleum or solely UST systems 
containing hazardous substances. If a ``partial'' state program is 
approved, EPA will administer the remaining part of the program. A 
``complete'' state program regulates both petroleum and hazardous 
substance tanks.
    (2) EPA will administer the UST program in Indian country, except 
where Congress has clearly expressed an intention to grant a state 
authority to regulate petroleum and hazardous substance USTs in Indian 
country. In either case, this decision will not impair a state's 
ability to obtain program approval for petroleum or hazardous 
substances in non-Indian country in accordance with this part.
    (3) Nothing in this subpart precludes a state from:
    (i) Adopting or enforcing requirements that are more stringent or 
more extensive than those required under this part; or
    (ii) Operating a program with a greater scope of coverage than that 
required under this part. Where an approved state program has a greater 
scope of coverage than required by federal law, the additional coverage 
is not part of the federally-approved program.
    (b) Definitions. (1) The definitions in 40 CFR part 280 apply to 
this entire part except as described below.
    (i) States may use the definitions associated with tank and piping 
secondary containment as defined in section 9003 of the Solid Waste 
Disposal Act.
    (ii) States may use the definitions associated with operator 
training as described in Sec.  9010 of the Solid Waste Disposal Act.
    (2) For the purposes of this part the term ``final approval'' means 
the approval received by a state program that meets the requirements in 
Sec.  281.11(b).

Subpart B--Components of a Program Application


Sec.  281.20  Program application.

    Any state that seeks to administer a program under this part must 
submit an application containing the following parts:
    (a) A transmittal letter from the Governor of the state requesting 
program approval;

[[Page 41678]]

    (b) A description in accordance with Sec.  281.21 of the state 
program and operating procedures;
    (c) A demonstration of the state's procedures to ensure adequate 
enforcement;
    (d) A Memorandum of Agreement outlining roles and responsibilities 
of EPA and the implementing agency;
    (e) An Attorney General's statement in accordance with Sec.  281.25 
certifying to applicable state authorities; and
    (f) Copies of all applicable state statutes and regulations.


Sec.  281.21  Description of state program.

    A state seeking to administer a program under this part must submit 
a description of the program it proposes to administer under state law 
in lieu of the federal program. The description of a state's existing 
or planned program must include:
    (a) The scope of the state program:
    (1) Whether the state program regulates UST systems containing 
petroleum or hazardous substances, or both;
    (2) Whether the state program is more stringent or broader in scope 
than the federal program, and in what ways; and
    (3) Whether the state has any existing authority in Indian country 
or has existing agreements with Indian tribes relevant to the 
regulation of underground storage tanks.
    (b) The organization and structure of the state and local agencies 
with responsibility for administering the program. The jurisdiction and 
responsibilities of all state and local implementing agencies must be 
delineated, appropriate procedures for coordination set forth, and one 
state agency designated as a ``lead agency'' to facilitate 
communications between EPA and the state.
    (c) Staff resources to carry out and enforce the required state 
program elements, both existing and planned, including the number of 
employees, agency where employees are located, general duties of the 
employees, and current limits or restrictions on hiring or utilization 
of staff.
    (d) An existing state funding mechanism to meet the estimated costs 
of administering and enforcing the required state program elements, and 
any restrictions or limitations upon this funding.


Sec.  281.22  Procedures for adequate enforcement.

    A state must submit a description of its compliance monitoring and 
enforcement procedures, including related state administrative or 
judicial review procedures.


Sec.  281.23  Memorandum of agreement.

    EPA and the approved state will negotiate a Memorandum of Agreement 
(MOA) containing proposed areas of coordination and shared 
responsibilities between the state and EPA and separate EPA and state 
roles and responsibilities in areas including, but not limited to: 
Implementation of partial state programs; enforcement; compliance 
monitoring; EPA oversight; and sharing and reporting of information. At 
the time of approval, the MOA must be signed by the Regional 
Administrator and the appropriate official of the state lead agency.


Sec.  281.24   Attorney General's statement.

    (a) A state must submit a written demonstration from the Attorney 
General that the laws and regulations of the state provide adequate 
authority to carry out the program described under Sec.  281.21 and to 
meet other requirements of this part. This statement may be signed by 
independent legal counsel for the state rather than the Attorney 
General, provided that such counsel has full authority to independently 
represent the state Agency in court on all matters pertaining to the 
state program. This statement must include citations to the specific 
statutes, administrative regulations, and where appropriate, judicial 
decisions that demonstrate adequate authority to regulate and enforce 
requirements for UST systems. State statutes and regulations cited by 
the state Attorney General must be fully effective when the program is 
approved.
    (b) If a state currently has authority over underground storage 
tank activities in Indian country, the statement must contain an 
appropriate analysis of the state's authority.

Subpart C--Criteria for No Less Stringent


Sec.  281.30  New UST system design, construction, installation, and 
notification.

    In order to be considered no less stringent than the corresponding 
federal requirements for new UST system design, construction, 
installation, and notification, the state must have requirements that 
ensure all new underground storage tanks, and the attached piping in 
contact with the ground and used to convey the regulated substance 
stored in the tank, conform to the following:
    (a) Be designed, constructed, and installed in a manner that will 
prevent releases for their operating life due to manufacturing defects, 
structural failure, or corrosion. Unless the state requires 
manufacturer and installer financial responsibility and installer 
certification in accordance with section 9003(i)(2) of the Solid Waste 
Disposal Act, then the state must meet the following:
    (1) New or replaced tanks and piping must use interstitial 
monitoring within secondary containment in accordance with section 
9003(i)(1) of the Solid Waste Disposal Act except as follows:
    (i) Underground piping associated with: Airport hydrant systems or 
field-constructed tanks greater than 50,000 gallons or
    (ii) Underground suction piping that meets Sec.  281.33(d)(2)(ii).
    (2) New motor fuel dispenser systems installed and connected to an 
UST system must be equipped with under-dispenser containment in 
accordance with section 9003(i)(1) of the Solid Waste Disposal Act.

    Note to paragraph (a). Codes of practice developed by nationally 
recognized organizations and national independent testing 
laboratories may be used to demonstrate that the state program 
requirements are no less stringent in this area.

    (b) Be provided with equipment to prevent spills and tank overfills 
when new tanks are installed or existing tanks are upgraded, unless the 
tank does not receive more than 25 gallons at one time. Flow 
restrictors used in vent lines are not allowable forms of overfill 
prevention when overfill prevention is installed or replaced.
    (c) All UST system owners and operators must notify the 
implementing agency of the existence of any new UST system and notify 
the implementing agency within a reasonable timeframe when assuming 
ownership of an UST system using a process designated by the 
implementing agency.


Sec.  281.31  Upgrading existing UST systems.

    In order to be considered no less stringent than the corresponding 
federal upgrading requirements, the state must have requirements that 
ensure existing UST systems meet the requirements of Sec.  281.30; are 
upgraded to prevent releases for their operating life due to corrosion, 
spills, or overfills; or are permanently closed with the following 
exceptions:
    (a) Upgrade requirements for previously deferred UST systems. 
Previously deferred airport hydrant fuel distribution systems and UST 
systems with field-constructed tanks must within three years of the 
effective date of its state requirements meet the requirements of Sec.  
281.30 or be permanently closed. This provision would not apply, 
however, to states that did not defer these UST systems and

[[Page 41679]]

already had, prior to the effective date of this provision, existing 
requirements with specified compliance periods for these types of UST 
systems.
    (b) Upgrade requirements for other UST systems. States may allow 
UST systems to be upgraded if the state determines that the upgrade is 
appropriate to prevent releases for the operating life of the UST 
system due to corrosion and spills or overfills.


Sec.  281.32  General operating requirements.

    In order to be considered no less stringent than the corresponding 
federal general operating requirements, the state must have 
requirements that ensure all new and existing UST systems conform to 
the following:
    (a) Prevent spills and overfills by ensuring that the space in the 
tank is sufficient to receive the volume to be transferred and that the 
transfer operation is monitored constantly;
    (b) Where equipped with cathodic protection, be operated and 
maintained by a person with sufficient training and experience in 
preventing corrosion, and in a manner that ensures that no releases 
occur during the operating life of the UST system;

    Note to paragraph (b).  Codes of practice developed by 
nationally recognized organizations and national independent testing 
laboratories may be used to demonstrate the state program 
requirements are no less stringent.

    (c) Be made of or lined with materials that are compatible with the 
substance stored; in order to ensure compatibility, the state 
requirements must also include provisions for demonstrating 
compatibility with new and innovative regulated substances or other 
regulated substances identified by the implementing agency or include 
other provisions determined by the implementing agency to be no less 
protective of human health and the environment than the provisions for 
demonstrating compatibility;
    (d) At the time of upgrade or repair, be structurally sound and 
upgraded or repaired in a manner that will prevent releases due to 
structural failure or corrosion during their operating lives;
    (e) Have spill and overfill prevention equipment periodically 
tested or inspected in a manner and frequency that ensures its 
functionality for the operating life of the equipment and have the 
integrity of containment sumps used for interstitial monitoring of 
piping periodically tested in a manner and frequency that prevents 
releases during the operating life of the UST system;
    (f) Have operation and maintenance walkthrough inspections 
periodically conducted in a manner and frequency that ensures proper 
operation and maintenance for the operating life of the UST system; and
    (g) Have records of monitoring, testing, repairs, and inspections. 
These records must be made readily available when requested by the 
implementing agency.


Sec.  281.33  Release detection.

    In order to be considered no less stringent than the corresponding 
federal requirements for release detection, the state must have 
requirements that at a minimum ensure all UST systems are provided with 
release detection that conforms to the following:
    (a) General methods. Release detection requirements for owners and 
operators must consist of a method, or combination of methods, that is:
    (1) Capable of detecting a release of the regulated substance from 
any portion of the UST system that routinely contains regulated 
substances--as effectively as any of the methods allowed under this 
part--for as long as the UST system is in operation. In comparing 
methods, the implementing agency shall consider the size of release 
that the method can detect and the speed and reliability with which the 
release can be detected.
    (2) Designed, installed, calibrated, operated and maintained so 
that releases will be detected in accordance with the capabilities of 
the method;
    (3) Operated and maintained, and electronic and mechanical 
components and other equipment are tested or inspected periodically, in 
a manner and frequency that ensures proper operation to detect releases 
for the operating life of the release detection equipment.
    (b) Phase-in of requirements. Release detection requirements must, 
at a minimum, be applied at all UST systems immediately, except for UST 
systems previously deferred under Sec.  280.10(a)(1). Release detection 
requirements must, at a minimum, be scheduled to be applied to those 
previously deferred UST systems as follows:
    (1) Immediately when a new previously deferred UST system is 
installed; and
    (2) For any previously deferred UST system within three years of 
the effective date of its state requirements. This provision would not 
apply, however, to states that did not defer these UST systems and 
already had, prior to the effective date of this provision, existing 
release detection requirements with specified compliance periods for 
these types of UST systems.
    (c) Requirements for petroleum tanks. All petroleum tanks must meet 
the following requirements:
    (1) All petroleum tanks must be sampled, tested, or checked for 
releases at least monthly, except that tanks installed before October 
13, 2015 or upgraded tanks (that is, tanks and piping protected from 
releases due to corrosion and equipped with both spill and overfill 
prevention devices) may temporarily use monthly inventory control (or 
its equivalent) in combination with tightness testing (or its 
equivalent) conducted every five years for the first 10 years after the 
tank is installed; and
    (2) New or replaced petroleum tanks must use interstitial 
monitoring within secondary containment in accordance with section 
9003(i)(1) of the Solid Waste Disposal Act except when the state 
requires manufacturer and installer financial responsibility and 
installer certification in accordance with section 9003(i)(2) of the 
Solid Waste Disposal Act.
    (d) Requirements for petroleum piping. All underground piping 
attached to the tank that routinely conveys petroleum must conform to 
the following:
    (1) If the petroleum is conveyed under greater than atmospheric 
pressure:
    (i) The piping must be equipped with release detection that detects 
a release within an hour by restricting or shutting off flow or 
sounding an alarm; and
    (ii) The piping must have monthly monitoring applied or annual 
tightness tests conducted.
    (2) If suction lines are used:
    (i) Tightness tests must be conducted at least once every three 
years, unless a monthly method of detection is applied to this piping; 
or
    (ii) The piping is designed to allow the contents of the pipe to 
drain back into the storage tank if the suction is released and is also 
designed to allow an inspector to immediately determine the integrity 
of the piping system.
    (3) Except as provided for in Sec.  281.30(a)(1) new or replaced 
petroleum piping must use interstitial monitoring within secondary 
containment in accordance with section 9003(i)(1) of the Solid Waste 
Disposal Act except when the state requires evidence of financial 
responsibility and certification in accordance with section 9003(i)(2) 
of the Solid Waste Disposal Act.
    (e) Requirements for hazardous substance UST systems. All new 
hazardous substance UST systems must use interstitial monitoring within 
secondary containment of the tanks and the attached underground piping 
that

[[Page 41680]]

conveys the regulated substance stored in the tank. For hazardous 
substance UST systems installed prior to October 13, 2015, owners and 
operators can use another form of release detection if the owner and 
operator can demonstrate to the state (or the state otherwise 
determines) that another method will detect a release of the regulated 
substance as effectively as other methods allowed under the state 
program for petroleum UST systems and that effective corrective action 
technology is available for the hazardous substance being stored that 
can be used to protect human health and the environment.


Sec.  281.34  Release reporting, investigation, and confirmation.

    In order to be considered no less stringent than the corresponding 
federal requirements for release reporting, investigation, and 
confirmation, the state must have requirements that ensure all owners 
and operators conform with the following:
    (a) Promptly investigate all suspected releases, including:
    (1) When unusual operating conditions, release detection signals 
and environmental conditions at the site suggest a release of regulated 
substances may have occurred or the interstitial space may have been 
compromised; and
    (2) When required by the implementing agency to determine the 
source of a release having an impact in the surrounding area; and
    (b) Promptly report all confirmed underground releases and any 
spills and overfills that are not contained and cleaned up.
    (c) Ensure that all owners and operators contain and clean up 
unreported spills and overfills in a manner that will protect human 
health and the environment.


Sec.  281.35  Release response and corrective action.

    In order to be considered no less stringent than the corresponding 
federal requirements for release response and corrective action, the 
state must have requirements that ensure:
    (a) All releases from UST systems are promptly assessed and further 
releases are stopped;
    (b) Actions are taken to identify, contain and mitigate any 
immediate health and safety threats that are posed by a release (such 
activities include investigation and initiation of free product 
removal, if present);
    (c) All releases from UST systems are investigated to determine if 
there are impacts on soil and groundwater, and any nearby surface 
waters. The extent of soil and groundwater contamination must be 
delineated when a potential threat to human health and the environment 
exists.
    (d) All releases from UST systems are cleaned up through soil and 
groundwater remediation and any other steps are taken, as necessary to 
protect human health and the environment;
    (e) Adequate information is made available to the state to 
demonstrate that corrective actions are taken in accordance with the 
requirements of paragraphs (a) through (d) of this section. This 
information must be submitted in a timely manner that demonstrates its 
technical adequacy to protect human health and the environment; and
    (f) In accordance with Sec.  280.67, the state must notify the 
affected public of all confirmed releases requiring a plan for soil and 
groundwater remediation, and upon request provide or make available 
information to inform the interested public of the nature of the 
release and the corrective measures planned or taken.


Sec.  281.36  Out-of-service UST systems and closure.

    In order to be considered no less stringent than the corresponding 
federal requirements for temporarily closed UST systems and permanent 
closure, the state must have requirements that ensure UST systems 
conform with the following:
    (a) Removal from service. All new and existing UST systems 
temporarily closed must:
    (1) Continue to comply with general operating requirements, release 
reporting and investigation, and release response and corrective 
action;
    (2) Continue to comply with release detection requirements if 
regulated substances are stored in the tank;
    (3) Be closed off to outside access; and
    (4) Be permanently closed if the UST system has not been protected 
from corrosion and has not been used in one year, unless the state 
approves an extension after the owner and operator conducts a site 
assessment.
    (b) Permanent closure of UST systems. All tanks and piping must be 
cleaned and permanently closed in a manner that eliminates the 
potential for safety hazards and any future releases. The owner or 
operator must notify the state of permanent UST system closures. The 
site must also be assessed to determine if there are any present or 
were past releases, and if so, release response and corrective action 
requirements must be complied with.
    (c) All UST systems taken out of service before the effective date 
of the federal regulations must permanently close in accordance with 
paragraph (b) of this section when directed by the implementing agency.


Sec.  281.37  Financial responsibility for UST systems containing 
petroleum.

    (a) In order to be considered no less stringent than the federal 
requirements for financial responsibility for UST systems containing 
petroleum, the state requirements for financial responsibility for 
petroleum UST systems must ensure that:
    (1) Owners and operators have $1 million per occurrence for 
corrective action and third-party claims in a timely manner to protect 
human health and the environment;
    (2) Owners and operators not engaged in petroleum production, 
refining, and marketing and who handle a throughput of 10,000 gallons 
of petroleum per month or less have $500,000 per occurrence for 
corrective action and third-party claims in a timely manner to protect 
human health and the environment;
    (3) Owners and operators of 1 to 100 petroleum USTs must have an 
annual aggregate of $1 million; and
    (4) Owners and operators of 101 or more petroleum USTs must have an 
annual aggregate of $2 million.
    (b) States may allow the use of a wide variety of financial 
assurance mechanisms to meet this requirement. Each financial mechanism 
must meet the following criteria in order to be no less stringent than 
the federal requirements. The mechanism must: Be valid and enforceable; 
be issued by a provider that is qualified or licensed in the state; not 
permit cancellation without allowing the state to draw funds; ensure 
that funds will only and directly be used for corrective action and 
third party liability costs; and require that the provider notify the 
owner or operator of any circumstances that would impair or suspend 
coverage.
    (c) States must require owners and operators to maintain records 
that demonstrate compliance with the state financial responsibility 
requirements, and these records must be made readily available when 
requested by the implementing agency.


Sec.  281.38  Lender liability.

    (a) A state program that contains a security interest exemption 
will be considered to be no less stringent than, and as broad in scope 
as, the federal program provided that the state's exemption:
    (1) Mirrors the security interest exemption provided for in 40 CFR 
part 280, subpart I; or

[[Page 41681]]

    (2) Achieves the same effect as provided by the following key 
criteria:
    (i) A holder, meaning a person who maintains indicia of ownership 
primarily to protect a security interest in a petroleum UST or UST 
system or facility or property on which a petroleum UST or UST system 
is located, who does not participate in the management of the UST or 
UST system as defined under Sec.  280.10 of this chapter, and who does 
not engage in petroleum production, refining, and marketing as defined 
under Sec.  280.200(b) of this chapter is not:
    (A) An ``owner'' of a petroleum UST or UST system or facility or 
property on which a petroleum UST or UST system is located for purposes 
of compliance with the requirements of 40 CFR part 280; or
    (B) An ``operator'' of a petroleum UST or UST system for purposes 
of compliance with the requirements of 40 CFR part 280, provided the 
holder is not in control of or does not have responsibility for the 
daily operation of the UST or UST system.
    (ii) [Reserved]
    (b) [Reserved]


Sec.  281.39  Operator training.

    In order to be considered no less stringent than the corresponding 
federal requirements for operator training, the state must have an 
operator training program that meets the minimum requirements of 
section 9010 of the Solid Waste Disposal Act.

Subpart D--Adequate Enforcement of Compliance


Sec.  281.40  Requirements for compliance monitoring program and 
authority.

    (a) Any authorized representative of the state engaged in 
compliance inspections, monitoring, or testing must have authority to 
obtain by request any information from an owner or operator with 
respect to the UST system(s) that is necessary to determine compliance 
with the UST regulations.
    (b) Any authorized representative of the state must have authority 
to require an owner or operator to conduct monitoring or testing.
    (c) Authorized representatives must have the authority to enter any 
site or premises subject to UST regulations or in which records 
relevant to the operation of the UST system(s) are kept, and to copy 
these records, obtain samples of regulated substances, and inspect or 
conduct the monitoring or testing of UST system(s).
    (d) State programs must have procedures for receipt, evaluation, 
retention, and investigation of records and reports required of owners 
or operators and must provide for enforcement of failure to submit 
these records and reports.
    (e)(1) State programs must have inspection procedures to determine, 
independent of information supplied by regulated persons, compliance 
with program requirements, and must provide for enforcement of failure 
to comply with the program requirements. States must maintain a program 
for systematic inspections of facilities subject to UST regulations in 
a manner designed to determine compliance or non-compliance, to verify 
accuracy of information submitted by owners or operators of regulated 
USTs, and to verify adequacy of methods used by owners or operators in 
developing that information.
    (2) When inspections are conducted, samples taken, or other 
information gathered, these procedures must be conducted in a manner 
(for example, using proper ``chain of custody'' procedures) that will 
produce evidence admissible in an enforcement proceeding, or in court.
    (f) Public effort in reporting violations must be encouraged and 
states must make available information on reporting procedures. State 
programs must maintain a program for investigating information obtained 
from the public about suspected violations of UST program requirements.
    (g) The state must maintain the data collected through inspections 
and evaluation of records in such a manner that the implementing agency 
can monitor over time the compliance status of the regulated community. 
Any compilation, index, or inventory of such facilities and activities 
shall be made available to EPA upon request.


Sec.  281.41  Requirements for enforcement authority.

    (a) Any state administering a program must have the authority to 
implement the following remedies for violations of state program 
requirements:
    (1) To restrain immediately and effectively any person by order or 
by suit in state court from engaging in any unauthorized activity that 
is endangering or causing damage to public health or the environment;
    (2) To sue in courts of competent jurisdiction to enjoin any 
threatened or continuing violation of any program requirement;
    (3) To assess or sue to recover in court civil penalties as 
follows:
    (i) Civil penalties for failure to notify or for submitting false 
information pursuant to tank notification requirements must be capable 
of being assessed up to $5,000 or more per violation.
    (ii) Civil penalties for failure to comply with any state 
requirements or standards for existing or new tank systems must be 
capable of being assessed for each instance of violation, up to $5,000 
or more for each tank for each day of violation. If the violation is 
continuous, civil penalties shall be capable of being assessed up to 
$5,000 or more for each day of violation.
    (4) To prohibit the delivery, deposit, or acceptance of a regulated 
substance into an underground storage tank identified by the 
implementing agency to be ineligible for such delivery, deposit, or 
acceptance in accordance with section 9012 of the Solid Waste Disposal 
Act.
    (b) The burden of proof and degree of knowledge or intent required 
under state law for establishing violations under paragraph (a)(3) of 
this section, must be no greater than the burden of proof or degree of 
knowledge or intent that EPA must provide when it brings an action 
under Subtitle I of the Solid Waste Disposal Act.
    (c) A civil penalty assessed, sought, or agreed upon by the 
implementing agency(ies) under paragraph (a)(3) of this section must be 
appropriate to the violation.


Sec.  281.42  Requirements for public participation.

    Any state administering a program must provide for public 
participation in the state enforcement process by providing any one of 
the following three options:
    (a) Authority that allows intervention analogous to Federal Rule 
24(a)(2) from Title IV of the Federal Rules of Civil Procedure, and 
assurance by the state that it will not oppose intervention under the 
state analogue to Rule 24(a)(2) on the ground that the applicant's 
interest is adequately represented by the state.
    (b) Authority that allows intervention of right in any civil action 
to obtain the remedies specified in Sec.  281.41 by any citizen having 
an interest that is or may be adversely affected; or
    (c) Assurance by the appropriate state agency that:
    (1) It will provide notice and opportunity for public comment on 
all proposed settlements of civil enforcement actions (except where 
immediate action is necessary to adequately protect human health and 
the environment);
    (2) It will investigate and provide responses to citizen complaints 
about violations; and

[[Page 41682]]

    (3) It will not oppose citizen intervention when permissive 
intervention is allowed by statute, rule, or regulation.


Sec.  281.43  Sharing of information.

    (a) States with approved programs must furnish EPA, upon request, 
any information in state files obtained or used in the administration 
of the state program. This information includes:
    (1) Any information submitted to the state under a claim of 
confidentiality. The state must submit that claim to EPA when providing 
such information. Any information obtained from a state and subject to 
a claim of confidentiality will be treated in accordance with federal 
regulations in 40 CFR part 2; and
    (2) Any information that is submitted to the state without a claim 
of confidentiality. EPA may make this information available to the 
public without further notice.
    (b) EPA must furnish to states with approved programs, upon 
request, any information in EPA files that the state needs to 
administer its approved state program. Such information includes:
    (1) Any information that is submitted to EPA without a claim of 
confidentiality; and
    (2) Any information submitted to EPA under a claim of 
confidentiality, subject to the conditions in 40 CFR part 2.

Subpart E--Approval Procedures


Sec.  281.50  Approval procedures for state programs.

    (a) The following procedures are required for all applications, 
regardless of whether the application is for a partial or complete 
program, as defined in Sec.  281.12.
    (b) Before submitting an application to EPA for approval of a state 
program, the state must provide an opportunity for public notice and 
comment in the development of its underground storage tank program.
    (c) When EPA receives a state program application, EPA will examine 
the application and notify the state whether its application is 
complete, in accordance with the application components required in 
Sec.  281.20. The 180-day statutory review period begins only after EPA 
has determined that a complete application has been received.
    (d) The state and EPA may by mutual agreement extend the review 
period.
    (e) After receipt of a complete program application, the 
Administrator will tentatively determine approval or disapproval of the 
state program. EPA shall issue public notice of the tentative 
determination in the Federal Register and other mechanisms to attract 
state-wide attention. Notice of the tentative determination must also:
    (1) Afford the public 30 days after the notice to comment on the 
state's application and the Administrator's tentative determination; 
and
    (2) Include a general statement of the areas of concern, if the 
Administrator indicates the state program may not be approved; and
    (3) Note the availability for inspection by the public of the state 
program application; and
    (4) Indicate that a public hearing will be held by EPA no earlier 
than 30 days after notice of the tentative determination unless 
insufficient public interest is expressed, at which time the Regional 
Administrator may cancel the public hearing.
    (f) Within 180 days of receipt of a complete state program 
application, the Administrator must make a final determination whether 
to approve the state program after review of all public comments. EPA 
will give notice of its determination in the Federal Register and 
codify the approved state program. The notice must include a statement 
of the reasons for this determination and a response to significant 
comments received.


Sec.  281.51  Revision of approved state programs.

    (a) Either EPA or the approved state may initiate program revision. 
Program revision may be necessary when the controlling federal or state 
statutory or regulatory authority is changed or when responsibility for 
the state program is shifted to a new agency or agencies. The state 
must inform EPA of any proposed modifications to its basic statutory or 
regulatory authority or change in division of responsibility among 
state agencies. EPA will determine in each case whether a revision of 
the approved program is required. Approved state programs must submit a 
revised application within three years of any changes to this part that 
requires a program revision.
    (b) Whenever the Administrator has reason to believe that 
circumstances have changed with respect to an approved state program or 
the federal program, the Administrator may request, and the state must 
provide, a revised application as prescribed by EPA.
    (c) The Administrator will approve or disapprove program revisions 
based on the requirements of this part and Subtitle I of the Solid 
Waste Disposal Act pursuant to the procedures under this section, or 
under Sec.  281.50 if EPA has reason to believe the proposed revision 
will receive significant negative comment from the public.
    (1) The Administrator must issue public notice of planned approval 
or disapproval of a state program revision in the Federal Register and 
other mechanisms to attract state-wide attention. The public notice 
must summarize the state program revision, indicate whether EPA intends 
to approve or disapprove the revision, and provide for an opportunity 
to comment for a period of 30 days.
    (2) The Administrator's decision on the proposed revision becomes 
effective 60 days after the date of publication in the Federal Register 
in accordance with paragraph (c)(1) of this section, unless significant 
negative comment opposing the proposed revision is received during the 
comment period. If significant negative comment is received, EPA must 
notify the state and within 60 days after the date of publication, 
publish in the Federal Register either:
    (i) A withdrawal of the immediate final decision, which will then 
be treated as a tentative decision in accordance with the applicable 
procedures of Sec.  281.50(e) and (f); or
    (ii) A notice that contains a response to significant negative 
comments and affirms either that the immediate final decision takes 
effect or reverses the decision.
    (d) Revised state programs that receive approval must be codified 
in the Federal Register.

Subpart F--Withdrawal of Approval of State Programs


Sec.  281.60  Criteria for withdrawal of approval of state programs.

    The Administrator may withdraw program approval when the Agency 
determines that a state no longer has adequate regulatory or statutory 
authority or is not administering and enforcing an approved program in 
accordance with this part. The state must have adequate capability to 
administer and enforce the state program. In evaluating whether such 
capability exists, the Agency will consider whether the state is 
implementing an adequate enforcement program by evaluating the quality 
of compliance monitoring and enforcement actions.


Sec.  281.61  Procedures for withdrawal of approval of state programs.

    (a) The following procedures apply when a state with an approved 
program voluntarily transfers to EPA those program responsibilities 
required by federal law.
    (1) The state must give EPA notice of the proposed transfer, and 
submit, at

[[Page 41683]]

least 90 days before the transfer, a plan for the orderly transfer of 
all relevant program information necessary for EPA to administer the 
program.
    (2) Within 30 days of receiving the state's transfer plan, EPA must 
evaluate the plan and identify any additional information needed by the 
federal government for program administration.
    (3) At least 30 days before the transfer is to occur, EPA must 
publish notice of the transfer in the Federal Register and other 
mechanisms to attract state-wide attention.
    (b) The following procedures apply when the Administrator considers 
withdrawing approval.
    (1) When EPA begins proceedings to determine whether to withdraw 
approval of a state program (either on its own initiative or in 
response to a petition from an interested person), withdrawal 
proceedings will be conducted in accordance with procedures set out in 
40 CFR 271.23(b) and (c), except for Sec.  271.23(b)(8)(iii) to the 
extent that it deviates from requirements under Sec.  281.60.
    (2) If the state fails to take appropriate action within a 
reasonable time, not to exceed 120 days after notice from the 
Administrator that the state is not administering and enforcing its 
program in accordance with the requirements of this part, EPA will 
withdraw approval of the state's program.
