National Technology Transfer and Advancement Act Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law No. 104–113, § 12(d) (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 standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies. The NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable voluntary consensus standards. The NTTAA does not apply to this action because it does not involve technical standards. Therefore, EPA did not consider the use of any voluntary consensus standards. J. Executive Order 12898: Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations Executive Order 12898, ‘‘Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations’’ (February 11, VerDate Aug<31>2005 17:22 Jun 01, 2006 Jkt 208001 1994), is designed to address the environmental and human health conditions of minority and low-income populations. EPA is committed to addressing environmental justice concerns and has assumed a leadership role in environmental justice initiatives to enhance environmental quality for all citizens of the United States. The Agency’s goals are to ensure that no segment of the population, regardless of race, color, national origin, income, or net worth bears disproportionately high and adverse human health and environmental impacts as a result of EPA’s policies, programs, and activities. Our goal is to ensure that all citizens live in clean and sustainable communities. This action merely proposes an interpretation of an existing rule and includes no changes that are expected to significantly or disproportionately impact environmental justice communities.

ACTION: Notice of proposed rulemaking. AGENCY: SUMMARY: This proposed rule would amend the reformulated gasoline (RFG) regulations to allow refiners and importers of reformulated gasoline blendstock for oxygenate blending, or RBOB, the option to use an alternative method of fulfilling a regulatory requirement to conduct quality assurance sampling and testing at downstream oxygenate blending facilities. This alternative method consists of a comprehensive program of quality assurance sampling and testing that would cover all terminals that blend oxygenate with RBOB in a specified reformulated gasoline covered area. The program would be carried out by an independent surveyor funded by industry. The program would be PO 00000 Frm 00038 Fmt 4702 Sfmt 4702 32015 conducted pursuant to a survey plan, approved by EPA, that is calculated to achieve the same objectives as the current regulatory quality assurance requirement. This proposed rule also would largely codify existing guidance for compliance by parties that handle pipeline interface with requirements for gasoline content standards, recordkeeping, sampling and testing. The proposed rule also contains new provisions which would provide additional flexibility to these regulated parties. The proposed rule would also establish gasoline sulfur standards for transmix processors and blenders that are consistent with the sulfur standards for other entities, such as pipelines and terminals, that are downstream of refineries in the gasoline distribution system, and would clarify the requirements for transmix processors under the Mobile Source Air Toxics program.

Refiner and Importer Quality Assurance Requirements for Downstream Oxygenate Blending A. Background The RFG regulations currently require RFG to contain a minimum of 2.0 weight percent oxygen. 40 CFR 80.41. To fulfill this requirement, oxygenate is VerDate Aug<31>2005 17:22 Jun 01, 2006 Jkt 208001 added either at the refinery before the gasoline is certified by the refiner as meeting RFG requirements, or it is added downstream from the refinery at an oxygenate blending facility. As discussed in more detail below, refiners often wish to require that more than the minimum amount of oxygenate be added downstream in order to include the additional oxygenate in their emissions performance compliance calculations. Although Congress recently removed the oxygen requirement for RFG in the Clean Air Act,1 we believe many refiners and importers may wish to continue to include oxygenate added downstream in their emissions compliance calculations. Under the current regulations, refiners must conduct a program of quality assurance testing at the downstream oxygenate blending facility in order to include the oxygenate in their compliance calculations. This proposed rule would provide an alternative QA requirement for these refiners and importers. Under the current regulations, when oxygenate is to be added to produce RFG at a downstream oxygenate blending facility, refiners produce a product called reformulated gasoline blendstock for oxygenate blending, or RBOB. RBOB is certified by the refiner, or by an importer who imports RBOB, as complying with all of the RFG requirements except the minimum 2.0 weight percent oxygen requirement. The oxygenate blender is responsible for complying with the oxygen requirement when the oxygenate is added to the RBOB to produce RFG at the oxygenate blending facility. Various oxygenates may be used to fulfill the oxygen requirement. Some oxygenates, such as methyl tertiary butyl ether, or MTBE, typically are added at the refinery. However, some oxygenates, such as ethanol, have a propensity to attract water, and, as a result, cannot be added at the refinery, particularly where the finished gasoline will be traveling through a pipeline on its way to terminals and retail gasoline stations. As a result, RFG containing ethanol is typically produced by blending the ethanol with RBOB at a blending facility downstream from the refinery that produced the RBOB. 1 1 Energy Policy Act of 2005, Pub. L. 109–58 (HR6), section 1504(a), 119 STAT 594, 1076– 1077(2005). In accordance with the Energy Policy Act, EPA has issued a rule amending the RFG regulations for California to remove the 2.0 weight percent oxygen standard (71 FR 8965 (February 22, 2006)), and has proposed a similar rule that would be applicable in the rest of the country (71 FR 9070 (February 22, 2006)). PO 00000 Frm 00040 Fmt 4702 Sfmt 4702 32017 Refiners and importers of RBOB are required to calculate compliance with the RFG emissions performance standards for VOC, NOX and toxics by sampling and testing a hand blended mixture of the RBOB and the type and amount of oxygenate that the refiner or importer of the RBOB designates must be added downstream. The type and amount of oxygenate to be added downstream must be indicated on the product transfer documents that accompany the gasoline when it is transferred to the downstream oxygenate blender. The oxygenate blender is required to add the type and amount of oxygenate designated on the product transfer documents. Under the current regulations, RBOB refiners and importers can designate either a specific type and specific amount of oxygenate to be added downstream, or they can designate one of two generic categories of RBOB: ‘‘anyoxygenate’’ RBOB or ‘‘ether-only’’ RBOB. 40 CFR 80.69(a)(8). Where the RBOB is designated as any-oxygenate RBOB, the refiner or importer must assume for purposes of its handblend that 2.0 weight percent ethanol will be added downstream. The downstream oxygenate blender may add any type of legal 2 oxygenate, to any-oxygenate RBOB in an amount sufficient to meet the minimum 2.0 weight percent requirement. Where the RBOB is designated as ether-only RBOB, the refiner or importer must assume for purposes of its handblend that 2.0 weight percent MTBE will be added downstream. The oxygenate blender may add any legal ether oxygenate to ether-only RBOB in an amount sufficient to meet the minimum 2.0 weight percent requirement. Where a specific type and amount of oxygenate is designated for the RBOB rather than one of the two generic designations, the regulations require the refiner or importer to conduct downstream oversight quality assurance (QA) sampling and testing of the downstream oxygenate blending facility. 40 CFR 80.69(a)(7). This is to ensure that the specific type and amount of oxygenate that is designated, which typically is greater than the 2.0 weight percent requirement, in fact is added to the RBOB by the oxygenate blender. In addition, the refiner or importer must have a contract with the oxygenate blender which requires the blender to comply with the blending procedures specified by the RBOB refiner or importer and allows the refiner or 2 Oxygenates that are allowed under EPA’s ‘‘substantially similar’’ rule and any section 211(f) waiver that may apply.

If the refiner or importer does not meet the contractual and quality assurance requirements and does not designate its RBOB as etheronly or any-oxygenate, the refiner or importer must assume for purposes of its handblend that 4.0 volume percent ethanol will be added to the RBOB downstream. B. Need for Action Recently, the states of New York and Connecticut promulgated state laws banning the use of MTBE in gasoline sold in these states. As a result, many refiners and importers that historically produced or imported RFG containing MTBE for the NY/CT RFG area currently produce or import RBOB for ethanol blending. Refiners in this area have indicated that, due to the complex gasoline marketplace in New York and Connecticut, it is extremely difficult, if not impossible, to track RBOB from the refinery where it is produced to the terminal where it is blended with ethanol in order to fulfill the downstream QA sampling and testing requirement. As a result, under the current regulations, refiners in the NY/ CT RFG area are effectively precluded from producing an RBOB which requires a specific type and amount of oxygenate, such as 10 volume percent ethanol, and instead must produce a generic any-oxygenate RBOB, which does not require the refiner to conduct downstream QA testing at the ethanol blender facility. As discussed above, for purposes of calculating compliance with RFG emissions performance standards, these refiners may then only include in their handblends ethanol in an amount which would result in gasoline having 2.0 weight percent ethanol (approximately 5.7 volume percent ethanol.) Some refiners have indicated that they will need to produce RBOB requiring 10 volume percent ethanol, which would allow them to include 10 volume percent ethanol for purposes of compliance calculations, in order to meet emissions performance standards. As a result, these refiners have asked EPA to allow use of an alternative method of meeting the downstream QA sampling and testing requirement. For the reasons discussed below, we believe it is appropriate to provide refiners and importers who produce or import RBOB for the NY/CT RFG area with an alternative means of meeting the QA sampling and testing requirement. We also believe it is appropriate to provide this alternative to refiners and importers who produce or import gasoline RBOB for other RFG areas. As a result, this proposed rule would amend the RFG regulations to provide an alternative QA sampling and testing option which will be available to any RBOB refiner or importer in any RFG covered area. As indicated above, we believe that providing this alternative QA requirement would be appropriate even after the 2.0 weight percent minimum oxygen standard is removed. C. This Action This proposal would provide RBOB refiners and importers the option to comply with an alternative QA requirement which consists of a program of sampling and testing designed to provide oversight of all terminals that blend ethanol with RBOB for use in a specified RFG covered area. Under this option, a refiner or importer would need to either arrange to have an independent surveyor conduct a program of compliance surveys, or participate in the funding of an organization which arranges to have independent surveyor conduct a program of compliance surveys. In either event, compliance surveys would need to be carried out by an independent surveyor pursuant to a survey plan calculated to achieve the same QA objectives as the current regulatory requirement. A detailed survey plan would be submitted to EPA for approval by September 1st of the year preceding the annual averaging period in which the alternative QA sampling and testing program would be implemented. The survey plan would include a methodology for determining when the survey samples will be collected, the location of the retail outlets where the samples will be collected, the number of samples to be included in the survey, and any other elements that EPA determines are necessary to achieve the same level of quality assurance as the current QA requirement. Under this alternative QA option, the independent surveyor would be required to obtain samples at retail stations in the RFG covered area in accordance with the survey plan and have the samples tested for type and amount of oxygenate. The sampling and testing conducted under this alternative QA option would be required to be done in accordance with the provisions in §§ 80.8 and 80.46. The surveyor would obtain from the retail outlet the product transfer documents associated with the gasoline, which will provide the surveyor with information regarding the type and amount of oxygenate that the gasoline is supposed to contain, and the VerDate Aug<31>2005 17:22 Jun 01, 2006 Jkt 208001 PO 00000 Frm 00041 Fmt 4702 Sfmt 4702 terminal that conducted the oxygenate blending. The surveyor would be required to notify EPA of any instance where the product transfer documents do not contain such information. If the test results show that the gasoline does not contain the type and/or the minimum amount of oxygenate indicated on the product transfer documents, the surveyor would be required to ask the terminal determined to have supplied the gasoline to produce documentation of the blending instructions from the refiner or importer of the RBOB. The surveyor would be required to notify EPA of any instances where the refiner’s or importer’s blending instructions indicate that the oxygenate blender did not add the type or minimum amount of oxygenate designated for the RBOB by the refinery or importer. The surveyor would be required to submit to EPA a report which includes the information and data collected during the survey, and to maintain records associated with the surveys for five years. This proposed rule would require each refiner and importer who chooses to comply with the alternative QA requirement to take all reasonable steps to ensure that parties downstream from the refiner or importer cooperate with the program by allowing the independent surveyor to collect samples, and by providing to the independent surveyor copies of product transfer documents and other information regarding the source of any gasoline received, the destination of any gasoline distributed, the oxygenate blending instructions for RBOB, and the rate the oxygenate was blended. In partial satisfaction of the ‘‘reasonable steps’’ requirement, the rule would require the refiner or importer to include such a requirement in contractual agreements with its branded downstream facilities. In addition, this proposed rule would require parties downstream from a refiner or importer that complies with the alternative QA requirement to include on product transfer documents the type and amount of oxygenate contained in the gasoline and identification of the oxygenate blending terminal that blended the gasoline. This proposed rule would require that the survey plan include a process for notifying all oxygenate blending terminals and other downstream parties in the affected area of the product transfer documentation requirement. Where a downstream party fails to receive notice of the product transfer requirement, the party would be required to begin complying with the E:\FR\FM\02JNP1.SGM 02JNP1 Federal Register / Vol. 71, No. 106 / Friday, June 2, 2006 / Proposed Rules product transfer requirement upon notification by EPA. We believe that use of this QA compliance alternative would result in oversight sampling and testing that is equivalent to the current regulatory QA requirement, and, in fact, may result in significantly superior QA oversight since the sampling and testing would be conducted by an independent surveyor in accordance with a comprehensive plan approved by EPA, rather than by individual refiners and importers. This rule would not have any adverse environmental impact, and would provide refiners and importers with additional flexibility in complying with the regulations. As a result, while this rulemaking was initiated in response to the compliance issues raised by refiners in the NY/CT area, we believe it is appropriate to provide this compliance alternative to refiners and importers supplying any RFG covered area. The rule, therefore, would provide this QA compliance alternative to any RBOB refiner or importer in any RFG area who either arranges to have an independent surveyor conduct a program of compliance surveys, or who participates in the funding of an organization that arranges to have an independent surveyor conduct a program of compliance surveys, in accordance with the provisions in this proposed rule. Compliance with this QA alternative would be optional. Refiners and importers may choose to comply with the existing QA requirement and not participate in a survey program. Refiners and importers who supply more than one RFG area may choose to participate in the survey program for one RFG area and comply with the existing QA requirement for another RFG area. This proposed rule would add a new paragraph (a)(11) to 40 CFR 80.69, which contains the current QA requirement. This proposed rule also would amend § 80.77 to require parties to include on product transfer documents the information required under § 80.69(a)(11) as described above. cchase on PROD1PC60 with PROPOSALS II. Requirements for Pipeline Interface A. Background Refined petroleum products that are transported by pipeline normally are pumped sequentially, as a continuous flow through the pipeline. As a result, some amount of mixing of adjacent product types normally occurs. The product in a pipeline between two adjacent volumes of petroleum product consists of a mixture of the two adjacent volumes and is called ‘‘interface.’’ Generally, interface is blended into the VerDate Aug<31>2005 17:22 Jun 01, 2006 Jkt 208001 two adjoining products that created the interface. For example, half of the interface between premium and regular gasoline is blended into the premium gasoline and half into the regular gasoline (called a ‘‘fifty percent cut’’ or a ‘‘mid-point cut.’’) However, certain product types, such as jet fuel, are not mixed with any other product type, and all of the interface that contains jet fuel is blended into the other product (called a ‘‘clean cut.’’) Where interface consists of a mixture of finished fuels that cannot be cut with adjoining product so as to produce a product that meets the specifications for a fuel that can be used or sold without further processing, the interface is called ‘‘transmix’’. Transmix is not blended into either of the two adjacent products transported by the pipeline, but is diverted by the pipeline as a distinct product into a separate storage tank. Transmix is generally transported via tank truck, pipeline or barge to a facility designed to separate the transmix into its fuel components. For example, where the transmix consists of gasoline and distillate fuel, the transmix may be transported to a ‘‘transmix processing’’ facility where the gasoline portion is separated from the distillate fuel. At locations where it is either relatively expensive or inconvenient to transport transmix to a transmix processing facility for separation, the transmix is sometimes blended into gasoline in very small amounts, typically around 0.25 volume percent of the gasoline. The reformulated gasoline (RFG) and anti-dumping requirements apply at any facility where gasoline is produced. See 40 CFR 80.2(h) and (i), 80.65(a), and 80.101. Gasoline most commonly is produced by processing crude oil at refineries, but it is also produced by other processes, such as combining blendstocks or adding blendstocks to finished gasoline. Gasoline is also produced when transmix is blended into gasoline, or when transmix is separated into gasoline and distillate fuel. Transmix blending is similar to adding blendstock to gasoline where the addition of the transmix, like blendstock, may change the properties of the gasoline. Similarly, the process of separating gasoline and distillate fuel may result in gasoline with different properties than the gasoline as originally certified by the refinery. Transmix processors and transmix blenders are refiners under the RFG/ anti-dumping regulations, but EPA has historically provided transmix processors and transmix blenders flexibility in complying with the refiner requirements. This proposed rule would PO 00000 Frm 00042 Fmt 4702 Sfmt 4702 32019 codify some of the existing practices into EPA regulations, and would also include modifications reflecting EPA experience. B. 1997 Notice of Proposed Rulemaking On July 11, 1997, EPA proposed to add a new § 80.84 to the RFG/antidumping regulations at 40 CFR Part 80 to clarify the manner in which interface, including transmix, would be treated under the RFG/anti-dumping regulations. The NPRM proposed requirements for designating different combinations of gasoline in interface. The NPRM also proposed requirements for transmix processors and transmix blenders that produce either RFG or conventional gasoline. The NPRM proposed to allow parties to blend transmix into conventional gasoline provided that the transmix resulted from normal pipeline operations, and either there was no means of transporting the transmix to a transmix processor via pipeline or water, or there was an historical practice of blending transmix at the facility before 1995. The rate of transmix blending was limited to the greater of 0.25 volume percent or the demonstrated blending rate in 1994. The NPRM proposed to allow transmix to be blended into RFG provided that the transmix resulted from normal pipeline operations, there was no means of transporting the transmix to a transmix processing facility via pipeline or water, and the party was unable to blend the transmix into conventional gasoline. The rate of transmix blending into RFG was limited to a maximum of 0.25 volume percent. The NPRM also proposed requiring transmix blenders to carry out a program of periodically sampling and testing of the RFG subsequent to transmix blending to ensure that the downstream standards were met. The NPRM proposed to require transmix processors who designate the gasoline produced from the transmix (such gasoline is one type of transmix gasoline product, or TGP) as conventional gasoline to exclude the TGP from anti-dumping compliance calculations for the transmix processing facility, but to include any blendstocks added to the TGP since such blendstocks would not previously have been included in any refinery’s compliance calculations. The NPRM proposed to require transmix processors who designate the gasoline produced from transmix as RFG to include the TGP, as well as any blendstocks used, in the RFG compliance calculations for the transmix processing facility to E:\FR\FM\02JNP1.SGM 02JNP1 cchase on PROD1PC60 with PROPOSALS 32020 Federal Register / Vol. 71, No. 106 / Friday, June 2, 2006 / Proposed Rules ensure that the gasoline produced using the transmix meets all RFG standards. Parties have been processing and blending transmix in accordance with EPA guidance which describes similar treatment of interface and transmix as that outlined in the July 11, 1997 NPRM. (See Reformulated Gasoline and Anti-dumping Questions and Answers (November 12, 1996)). Our experience since the guidance was issued indicates that the approach taken in the guidance is mostly appropriate, but that some revisions are warranted. EPA is also aware, from recent discussions with several pipeline operators, that volumes of transmix may increase as pipelines begin transporting ultra-low sulfur diesel fuel. EPA had anticipated that transporting ultra-low sulfur diesel would require greater volumes of diesel to be cut as interface into other highersulfur distillate fuels such as heating oil and jet fuel. However, some pipelines have indicated they intend to change their product sequencing by transporting volumes of ultra-low sulfur diesel between volumes of gasoline, in order to minimize sulfur contamination of the ultra-low sulfur diesel. This change would increase the number of gasoline/diesel interfaces cut to transmix, and increase the overall volume of transmix. Pipeline operators have also indicated that transporting ultra-low sulfur diesel fuel will cause them to generate transmix at locations where they have not historically generated transmix. In this proposed rule, we are including the provisions in § 80.84, which were previously proposed in the July 11, 1997 NPRM, with certain changes made in response to the comments we received on the NPRM, as discussed below. We believe it is appropriate to include in this proposal the provisions in § 80.84 given the length of time since they were originally proposed, and to include changes made in response to prior comments. We have also added several new provisions in this proposal clarifying, and in some instances expanding, the flexibilities available to transmix processors and transmix blenders for complying with the RFG/antidumping regulations. This proposed rule also includes modest recordkeeping requirements in §§ 80.74 and 80.104 which would require parties that handle interface and transmix to keep records verifying that the requirements of § 80.84 were met. In addition, this proposed rule includes provisions for transmix processors and transmix blenders related to gasoline sulfur and air toxics. This proposed rule only addresses gasoline produced by transmix processors and transmix VerDate Aug<31>2005 17:22 Jun 01, 2006 Jkt 208001 blenders. Distillate fuel produced by transmix processors and transmix blenders is addressed in the diesel sulfur regulations under 40 CFR part 80, subpart I. EPA believes the flexibilities available in this proposed rule are appropriate given the unique roles that transmix processors and transmix blenders fill in the petroleum products distribution system. Although transmix processors and transmix blenders are refiners under EPA’s regulations, almost all of the gasoline and distillate fuel they produce is derived from fuel which has already been produced and certified by an upstream refinery. Thus, this proposed rule would allow transmix processors the flexibility to exclude from their antidumping compliance calculations conventional gasoline that they recover directly from transmix, since the conventional gasoline has already been accounted for in the compliance calculations of an upstream refinery. Similarly, this proposed rule would allow transmix processors to only have to meet the downstream sulfur standards for gasoline they recover directly from transmix, since the gasoline has already been accounted for in the compliance calculations of an upstream refinery. However, transmix processors must comply with all refiner standards at each of their transmix processing facilities for any blendstocks they add to gasoline. Lastly, this proposed rule would allow transmix blenders to blend transmix into gasoline without restriction on location or rate, provided the endpoint of the transmixblended gasoline does not exceed 437 degrees Fahrenheit, and that the gasoline meets all applicable downstream standards. C. Pipelines This proposed rule includes designations for pipeline interface that are consistent with the designations in EPA’s current guidance and the 1997 NPRM. The designations for pipeline interface are primarily intended to ensure that pipelines cut their interfaces in a manner that maintains the quality of any RFG or VOC-controlled gasoline transported by a pipeline. For example, interfaces between volumes of RFG and conventional gasoline should be cut into the conventional gasoline to maintain the quality of the RFG. Regardless of gasoline product designation, all gasoline containing interface must meet all downstream standards, including but not limited to any standards and requirements that apply downstream of the refinery in 40 CFR Part 80 and the Clean Air Act. PO 00000 Frm 00043 Fmt 4702 Sfmt 4702 D. Transmix Processors 1. Comments on the 1997 Notice of Proposed Rulemaking EPA received a number of comments on the 1997 NPRM regarding transmix processors. One commenter said that the definition of transmix should be changed since transmix processors and transmix blenders sometimes process or blend mixtures of fuels that were unintentionally combined in tanks. Although such mixtures are similar in composition to transmix, they do not fit the definition of transmix proposed in the 1997 NPRM, which specified that transmix must be generated in a pipeline. EPA agrees that a product that in composition is similar to transmix, and that is produced by unintentionally mixing gasoline and distillate fuel in tanks, should be afforded the same treatment as transmix product generated in a pipeline. EPA also understands that transmix may include mixtures of gasoline and distillate fuel produced through normal operational activities at pipelines and terminals, such as draining tanks, or draining piping and hoses used to transfer gasoline or distillate fuel to tanks or trucks, or from a safety relief valve discharging to protect equipment from overpressuring. As a result, § 80.84(e) in this proposed rule specifically allows such products to be covered under the transmix provisions. EPA is aware that some transmix processors and transmix blenders may also be adding feedstocks to their transmix that were not produced from normal pipeline interface, or from inadvertently mixing gasoline and distillate fuel in tanks, or through normal operational activities at pipelines and terminals. Mixing other feedstocks in transmix prior to processing may cause these other feedstocks to be inappropriately accounted for under the antidumping regulations and gasoline sulfur regulations, as discussed later. The flexibility provided in this rule extends only to transmix composed of pipeline interface, mixtures of gasoline and distillate fuel that were unintentionally combined in a tank, and mixtures of gasoline and distillate fuel produced through normal operational activities at pipelines and terminals. A transmix processor or transmix blender who adds feedstocks derived from any other sources to their transmix must comply with all the standards applicable to a refiner under EPA’s regulations for all the gasoline they produce during a compliance period, including but not limited to any standards and requirements in 40 CFR parts 79, 80 and E:\FR\FM\02JNP1.SGM 02JNP1 cchase on PROD1PC60 with PROPOSALS Federal Register / Vol. 71, No. 106 / Friday, June 2, 2006 / Proposed Rules the Clean Air Act. Transmix processors that add feedstocks from any other sources should also take extra care to be sure that they are complying with Subtitle C of the Resource Conservation and Recovery Act (RCRA), 42 U.S.C. 6921–6939(e), and any state provision authorized pursuant to Section 3006 of RCRA, 42 U.S.C. 6926. One commenter said that the 1997 NPRM should clarify that the transmix processing requirements do not apply to transmix processed by a crude oil refinery where the transmix is received into a crude or other feedstock stream and is not separated before it is added to other feedstocks. EPA believes that the regulations in this proposed rule are clear in this regard, since they specifically apply to persons who separate transmix at a transmix processing facility. The term ‘‘transmix processing facility’’ is defined as excluding refineries that ‘‘produce gasoline by processing crude oil’’. Such refineries must comply with all existing refiner requirements, and would not be eligible to take advantage of the flexibilities available in this proposed rule. Some commenters said that they do not know the source of the transmix and, therefore, would not know the original designation of the gasoline portion of the transmix (e.g., RFG, conventional gasoline, blendstocks). The commenters said that the transmix processor should not be required to track and segregate transmix generated from different types of gasoline or blendstocks. This proposed rule would not require a transmix processor to track and segregate transmix. However, § 80.65 requires the transmix processor to designate the gasoline portion (i.e., conventional gasoline, RFG, or RBOB) that is separated from the distillate fuel. One commenter said that, under previous guidance, EPA provided for the exclusion of the transmix-based portion of conventional gasoline from anti-dumping compliance calculations as an option, whereas in the 1997 NPRM, the exclusion would be mandatory. The commenter believes the exclusion should be optional. Another commenter believes that transmix processing improves the quality of the gasoline separated from transmix by removing more heavy aromatics and sulfur compounds and improving E300 distillation point, and therefore, TGP should be included in compliance calculations for conventional gasoline to give credit for the improvements. EPA agrees with the commenters, and this proposed rule would modify the 1997 NPRM to allow the exclusion of the TGP from anti-dumping compliance VerDate Aug<31>2005 17:22 Jun 01, 2006 Jkt 208001 calculations to be optional, provided the TGP meets all of the downstream standards for conventional gasoline. However, in order to prevent transmix processors from selectively including only high quality TPG batches in their compliance calculations, while excluding those of low quality, transmix processors must consistently include or exclude TGP in their compliance calculations during each annual compliance period, with one exception. The exception occurs if transmix contains gasoline blendstocks that are derived from pipeline interface. EPA understands that some pipelines transport gasoline blendstocks, and that these pipelines may cut interfaces containing gasoline blendstock to a transmix tank. If a transmix processor produces conventional gasoline from transmix containing gasoline blendstocks and was allowed to exclude the TGP from their anti-dumping compliance calculations, the finished conventional gasoline would not be included in any refiner’s anti-dumping compliance calculations. Thus, under this proposal, if a transmix processor produces conventional gasoline at a transmix processing facility from transmix containing gasoline blendstocks derived from pipeline interface, the transmix processor must consistently include all TGP produced during a compliance period in their antidumping compliance calculations for that transmix processing facility. As discussed previously, if transmix processors add any feedstocks to their transmix that were not produced from normal pipeline interface, or from inadvertently mixing gasoline and distillate fuel in tanks, or through normal operational activities at pipelines and terminals, they would need to comply with all standards applicable to refiners under EPA’s regulations for all the gasoline they produce during a compliance period. This proposed rule would also require any RFG or RBOB produced by a transmix processor to be included in the RFG compliance calculations for the transmix processing facility. This proposed rule would also modify the 1997 NPRM by treating TGP as a blendstock when the transmix processor mixes the TGP with other blendstock(s) to produce conventional gasoline. In this situation, the TGP would be included in compliance calculations for the resulting conventional gasoline. We believe it is appropriate to treat TGP as a blendstock rather than as a previously certified gasoline in this situation, since the TGP is likely to have undergone changes as a result of having been interfaced with another product and PO 00000 Frm 00044 Fmt 4702 Sfmt 4702 32021 separated through transmix processing. For example, one transmix processor indicated that their TGP could not be directly sold as gasoline because it does not meet standards for octane or Reid vapor pressure. This approach is consistent with the approach taken in both the 1997 NPRM and the Question and Answer guidance with regard to RFG, where TGP is required to be included in compliance calculations when it is mixed with blendstock to produce RFG. Where TGP is sold as a blendstock, the transmix processor would be required to exclude the TGP from compliance calculations, with one exception. The exception is when the transmix processor sells the TGP to an oxygenate blender as a blendstock which becomes conventional gasoline solely upon the addition of an oxygenate, such as ethanol or MTBE. In this circumstance, the transmix processor would need to include the TGP in compliance calculations. This exception would not apply if the TGP is combined with any other nonoxygenated blendstocks to produce conventional gasoline. Thus, in order for a transmix processor to properly account for any TGP sold as a blendstock in compliance calculations for a transmix processing facility, the transmix processor must clearly state on the TGP product transfer documents whether or not the TGP may only be combined with an oxygenate to produce conventional gasoline. This approach is consistent with the anti-dumping regulations at § 80.101(d)(3), which require blendstocks that become conventional gasoline solely upon the addition of an oxygenate to be included in anti-dumping compliance calculations for the refiner that produced the blendstock. Transmix processors also sometimes blend sub-octane TGP with previously certified premium gasoline (PCG) to produce regular gasoline. EPA is proposing that transmix processors which blend sub-octane TGP with premium PCG to produce conventional gasoline must include the TGP in compliance calculations for the transmix processing facility, but may meet the sampling and testing requirements in one of three ways. First, the transmix processor may directly measure the properties of the TGP and treat each volume of TGP blended with PCG as a separate batch for purposes of compliance calculations. As a second alternative, the transmix processor may measure the volume and properties of the PCG prior to blending with the TGP, then measure the volume and properties of the gasoline subsequent to blending E:\FR\FM\02JNP1.SGM 02JNP1 32022 Federal Register / Vol. 71, No. 106 / Friday, June 2, 2006 / Proposed Rules cchase on PROD1PC60 with PROPOSALS with the TGP, and calculate the volume and properties of the TGP by subtracting the volume and properties of the PCG from the volume and properties of the gasoline subsequent to blending. As a third alternative, the transmix processor may demonstrate compliance using the procedures in § 80.101(g)(9). Where TGP is mixed with previously certified gasoline to produce RFG or RBOB, the transmix processor must demonstrate compliance using the procedures in § 80.65(i). One commenter said that EPA should allow transmix processors to blend oxygenates and other blendstocks into transmix-based conventional gasoline to produce RFG. This proposed rule would address this comment by allowing transmix processors to treat their TGP as a blendstock, and combine the TGP with other blendstocks to produce either conventional or reformulated gasoline. In this situation, the transmix processor would be required to fulfill all the requirements and standards for RFG that apply to a refiner. 2. Issues Not Addressed in the 1997 NPRM a. Gasoline Sulfur. In the preamble to the gasoline sulfur regulations, EPA indicated that the Agency would establish requirements for transmix processors in a future rulemaking (65 FR 6800, February 10, 2000). Therefore, as part of this rulemaking, EPA is also including proposed requirements for transmix processors and transmix blenders under the gasoline sulfur regulations at 40 CFR part 80, subpart H. As under the RFG/anti-dumping rule, transmix processors and transmix blenders are refiners under the gasoline sulfur regulations. As a result, transmix processors and transmix blenders are subject to the refinery sulfur standards under § 80.195 of the gasoline sulfur regulations. However, for reasons discussed below, we believe it is appropriate that such parties be held to the gasoline sulfur standards applicable to downstream parties under §§ 80.210 and 80.220 of the gasoline sulfur regulations, and not be held to the more stringent refinery standards in § 80.195. As indicated above, transmix processors generally do not control their feedstock, but receive mixtures of products from upstream refineries. The gasoline portion of transmix may be relatively high in sulfur if it was originally produced by a small refiner, a refiner producing gasoline for use in the Geographic Phase-in Area (GPA), or a refiner who has been given a temporary hardship extension to produce relatively high sulfur gasoline. As a result, holding transmix processors VerDate Aug<31>2005 17:22 Jun 01, 2006 Jkt 208001 to the downstream sulfur standards rather than the more stringent refinery standards would provide transmix processors the flexibility to recover gasoline originally produced by small refiners, refiners of GPA gasoline, or temporary hardship refiners. To ensure compliance with the applicable downstream sulfur standards, transmix processors will be required to test any gasoline produced from transmix for sulfur content. Under this proposed rule, transmix processors who add blendstocks not derived from transmix to their recovered gasoline would be required to meet all of the requirements and standards that apply to refiners under 40 CFR Part 80, subpart H, for such blendstocks. Where certain requirements are met, the transmix processor may use sulfur test results from the blendstock supplier for purposes of meeting the sampling and testing requirements under the sulfur rule. As mentioned previously, EPA has learned that some transmix processors have added feedstocks to their transmix, before the transmix is processed, that are not produced from pipeline interface, or from mixtures of gasoline and distillate fuel unintentionally combined in a tank, or from normal operations at pipelines and terminals. Under this proposal, transmix processors that use these other feedstocks would need to meet all EPA standards applicable to a refiner for all the gasoline they produce during a compliance period, including the refinery level sulfur standards in 40 CFR 80.195. These transmix processors could not utilize the flexibilities in this rule because they have chosen to use feedstocks that have not been previously accounted for by a refinery in the production of gasoline. When the transmix is processed, the previously compliant gasoline present in the transmix and the other feedstocks both distill out of the transmix together as a fungible product, and the transmix processor cannot distinguish exactly which portion of the TGP was derived from previously compliant gasoline and which was derived from other feedstocks. Thus, EPA proposes limiting the flexibility allowed by this proposed rule to gasoline produced from transmix, only if the transmix was produced from pipeline interface, or from mixtures of gasoline and distillate fuel that were unintentionally combined in a tank, or from mixtures of gasoline and distillate fuel produced from normal operational activities at pipelines and terminals. Transmix processors who add any other material to their transmix would need to comply PO 00000 Frm 00045 Fmt 4702 Sfmt 4702 with all EPA standards applicable to a refiner for all the gasoline they produce during a compliance period, including the refinery level sulfur standards in 40 CFR 80.195. This proposed rule would, however, allow transmix processors that produce gasoline from pipeline interface to meet the less stringent downstream gasoline sulfur standards, even if the interface contains small amounts of gasoline blendstocks that are transported via pipeline as a normal part of pipeline operations. EPA believes it is appropriate to allow transmix processors that produce gasoline from these interface mixtures to meet the downstream sulfur standards because they do not have the same level of control over their transmix as the transmix processors that intentionally introduce other feedstocks into the production process. Furthermore, because the volume of gasoline blendstocks in the transmix will be relatively small and since the gasoline will still have to meet downstream standards, EPA believes the environmental consequences of allowing these transmix processors to meet the less stringent downstream sulfur standard should be negligible. This proposed rule would add a new § 80.213 to the gasoline sulfur regulations. This section contains the additional requirements for demonstrating compliance with the gasoline sulfur rule discussed above for refiners who process or blend transmix in accordance with the provisions in § 80.84. EPA believes that the additional proposed requirements for transmix processors and transmix blenders in § 80.213 are necessary to maintain the flexibility of the current practices regarding transmix, and will not result in any adverse environmental consequences. This proposed rule would also add modest recordkeeping requirements to § 80.365 which require parties to retain records of any sampling and testing required under § 80.213. b. Air Toxics. The mobile source air toxics (MSAT) rule (66 FR 17230, March 29, 2001) requires the annual average toxics performance of a refinery’s or importer’s gasoline to be at least as clean as the average of its gasoline during the three-year baseline period 1998–2000. The MSAT requirements apply separately to RFG and to conventional gasoline. MSAT compliance is determined from the same gasoline data used by a refiner to determine its compliance with the RFG or anti-dumping requirements. As a result, only gasoline which would be included in the RFG or anti-dumping compliance determination of a refiner is E:\FR\FM\02JNP1.SGM 02JNP1 Federal Register / Vol. 71, No. 106 / Friday, June 2, 2006 / Proposed Rules included in the refiner’s MSAT baseline and compliance determinations. Most, if not all, transmix processors have unique individual MSAT baselines. Under MSAT, those with unique individual MSAT baselines (§ 80.915) are subject to their MSAT baseline up to their associated MSAT baseline volume (§ 80.850). Gasoline production above the MSAT baseline volume is subject to either the RFG toxics performance standard (§ 80.41) or to the refiner’s anti-dumping standard (§ 80.91). Because these standards are equal to or less stringent than the refiner’s MSAT baseline, they offer some flexibility to the refiner’s overall compliance with its MSAT standard. Because gasoline demand is increasing, EPA expects that this provision will provide most refiners with some degree of MSAT compliance flexibility. The MSAT rules also provide for limited credit and deficit carryover, allowing refiners to weather slightly off years with better toxics performance in an adjacent year (§ 80.815). Finally, because all refiners are subject to MSAT standards which are typically more stringent than the RFG toxics performance standard or their individual anti-dumping standard, it is likely that the gasoline portion of the transmix is also cleaner with respect to toxics performance than it was during the baseline period 1998–2000, thus providing some immediate flexibility to transmix processors and transmix blenders. This action clarifies that any gasoline or blendstock a transmix processor includes in their RFG or anti-dumping compliance determination is also included in their MSAT compliance calculations. Also, EPA has recently proposed to replace the existing MSAT regulations with a standard that would limit the benzene content of gasoline to an annual average of 0.62 percent by volume for most refiners, beginning in 2011. See 71 FR 15803 (March 29, 2006). The proposed toxics regulations would exempt transmix processors from the new benzene standard for any gasoline they recover from transmix, but require transmix processors to meet the standard for any blendstocks they add to transmix. cchase on PROD1PC60 with PROPOSALS E. Transmix Blenders 1. Comments on the 1997 Notice of Proposed Rulemaking One commenter was concerned that the sampling and testing procedures in the 1997 NPRM for blends of transmix and RFG, which would be performed after blending the transmix, may not prevent the release of noncompliant VerDate Aug<31>2005 17:22 Jun 01, 2006 Jkt 208001 RFG in the distribution system. For reasons discussed below, however, EPA believes that commercial standards limit transmix blending to such small percentages, that blending transmix in RFG will cause essentially no change in the emissions performance of the RFG. This proposed rule would specifically require that all gasoline produced by transmix blenders have an endpoint less than 437 degrees Fahrenheit. As described below, as a practical matter, EPA believes that this endpoint standard will effectively prevent the blending of transmix into gasoline from causing any appreciable changes in gasoline emissions performance. One commenter said that the 1996 Question and Answer guidance regarding transmix blended into conventional gasoline requires that the transmix be blended at a rate no greater than the historical rate that was used by the pipeline, whereas the NPRM provided that the transmix be blended at a rate no greater than the historical rate at the terminal or 0.25 volume percent, whichever is greater. The commenter said the NPRM did not cover a situation where, historically, transmix was moved through a pipeline to a terminal that is no longer used for blending transmix, and the transmix is currently moved through the same pipeline but blended at an intermediate terminal which historically had not been used for blending transmix. The commenter recommended that the language in the Q&A guidance, which covers this situation by allowing blending at the historical rate used by the pipeline rather than by the terminal, be adopted in the regulations. We believe the Q&A guidance is consistent with the 1997 NPRM in stating that if a pipeline stops blending transmix at a terminal, that the pipeline may not begin blending transmix at a second terminal at a rate equal to the first terminal’s blending rate. The Q&A guidance states: ‘‘* * * the transmix must be present in a terminal from which there is no out-bound pipeline or water transportation by which the transmix could be transported to a transmix processor, or the pipeline’s historical practice at the terminal [emphasis added] (the practice beginning at least before January, 1994) has been to blend all transmix into conventional gasoline without further processing.’’ This language indicates that the criteria regarding historical practice applies to the terminal in which the transmix was blended by the pipeline. Where a pipeline blends transmix at more than one terminal, the historical practice criterion would apply separately to each of the pipeline’s PO 00000 Frm 00046 Fmt 4702 Sfmt 4702 32023 terminals at which transmix is blended. However, as described below, this proposed rule would change this approach. 2. This Proposal This proposed rule would eliminate the historical practice criterion for determining amounts of transmix to be blended into conventional gasoline and the locations where this may occur, and also would eliminate the 0.25 volume percent limit for blending transmix in reformulated gasoline. This proposed rule would instead allow transmix to be blended into conventional or reformulated gasoline in any location and in any amount, provided the endpoint of the transmix-blended gasoline does not exceed 437 degrees Fahrenheit,3 and meets all other applicable downstream standards. As EPA’s diesel sulfur regulations begin phasing in, transmix will be generated at new locations. EPA believes it is appropriate to allow the flexibility to blend transmix into gasoline at locations which have not historically blended transmix, provided the endpoint of the transmix-blended gasoline does not exceed 437 degrees Fahrenheit, and the gasoline meets all other applicable downstream standards. In addition, EPA believes it is appropriate to use gasoline endpoint to regulate transmix blending because it takes into account the quality of the transmix-blended gasoline. The historical practice criterion for conventional gasoline and the 0.25 volume percent limit for RFG were crude approaches that did not account for the variability of transmix and its effect on the gasoline into which it was blended. EPA believes that blending small percentages of transmix in gasoline should be allowed at any facility, provided the facility takes appropriate steps to ensure that the endpoint of the transmix-blended gasoline does not exceed 437 degrees Fahrenheit. Transmix typically contains significant percentages of distillate fuels such as diesel fuel or heating oil, and distillate fuels have higher boiling points and much lower octane ratings than 3 437 degrees Fahrenheit is the maximum allowable endpoint for gasoline specified in ASTM’s standard for automotive spark-ignition engine fuel, D 4814–88. Gasoline endpoint is measured using ASTM D86–01. ASTM D86–01 measures the percentage of a gasoline sample that evaporates, as a function of temperature, as the sample is heated up under controlled conditions. Endpoint is the temperature at which all the volatile portion of a gasoline sample is evaporated. ASTM D4814–88 specifies a maximum allowable endpoint of 437 degrees Fahrenheit in order to limit the amount of higher-boiling point compounds that can be present in the gasoline. E:\FR\FM\02JNP1.SGM 02JNP1 32024 Federal Register / Vol. 71, No. 106 / Friday, June 2, 2006 / Proposed Rules cchase on PROD1PC60 with PROPOSALS gasoline. EPA’s existing guidance regarding transmix blending reflected a concern that blending excessive amounts of transmix in gasoline could have an appreciable effect on emissions. However, EPA believes that where transmix is blended at sufficiently low percentages, such that the endpoint of the transmix-blended gasoline does not exceed 437 degrees Fahrenheit, the emissions effect of blending transmix in gasoline will be negligible. In addition to affecting gasoline endpoint and octane, blending transmix in gasoline also affects parameters in EPA’s complex model, the model used to ensure that imported or produced gasoline complies with EPA standards. Although the complex model does not use gasoline endpoint or octane to predict gasoline emissions, the complex model does use several other gasoline parameters to predict gasoline emissions. These parameters include sulfur content, benzene content, aromatics content, olefin content, oxygen content, Reid vapor pressure (RVP), and two distillation points (E200 and E300). Compared to gasoline, the distillate fuel portion of transmix contains much less benzene, olefins, and oxygen (typically zero for all three parameters), has a much lower RVP, may contain a moderately greater percentage of aromatics, has significantly lower (typically zero) E200 and E300 distillation points, and may contain more sulfur. EPA is primarily concerned with the effect of transmix blending on average gasoline sulfur content. Beginning in 2006, EPA’s gasoline sulfur regulations specify that all gasoline produced by most refineries or imported by each importer must contain an annual average sulfur content of 30 ppm or less, in order to help significantly reduce emissions from gasoline-powered vehicles.4 Transmix may contain significant percentages of high sulfur distillate fuel such as heating oil, nonroad diesel or jet fuel, and blending transmix containing high sulfur distillate fuels into gasoline could cause an increase in the sulfur content of the gasoline. EPA believes, for two reasons, that the potential increase in gasoline sulfur due to blending transmix into gasoline would be so small, that the effect on emissions from gasoline engines would be negligible. The first reason is that the 4 Gasoline produced by most refineries or imported by each importer must also contain no more than 80 ppm sulfur per gallon beginning in 2006. However, EPA has allowed flexibility for some refiners to be able to produce gasoline that is higher on both an average basis and a per gallon basis through December 31, 2010. VerDate Aug<31>2005 17:22 Jun 01, 2006 Jkt 208001 percentage of transmix that can be blended into gasoline is significantly limited by the amount of distillate fuel in the transmix. Distillate fuels have much higher boiling points than gasoline, so transmix blenders must limit the addition of transmix so that the endpoint of the transmix-blended gasoline does not exceed 437 degrees Fahrenheit. Refiners already have to meet the ASTM endpoint standard under the ‘‘substantially similar’’ requirements for gasoline (56 FR 5352, February 11, 1991). Consequently, transmix which contains relatively high percentages of distillate fuel must be blended into gasoline at relatively low percentages so that the endpoint of the transmix-blended gasoline does not exceed 437 degrees Fahrenheit. The second reason is that EPA anticipates that the distillate fuel portion of transmix will contain significantly less sulfur beginning June, 2006, when the sulfur standard for highway diesel fuel drops sharply from 500 to 15 parts per million (ppm). Beginning in June, 2006, EPA estimates that the national average sulfur content of transmix will drop from approximately 800 ppm to 141 ppm, using product sulfur levels and pipeline product sequencing arrangements from Chapter 7 of the Regulatory Support Document (RSD) for the nonroad diesel sulfur regulations. Blending 0.25 volume percent transmix containing 141 ppm sulfur into gasoline raises the sulfur level of the gasoline by only approximately 0.3 ppm. Although the percentage of gasoline that is blended with transmix would be anticipated to increase under this proposed rule, EPA anticipates that transmix will be blended at no more than 0.25 volume percent on average nationwide, and that the overall average increase in gasoline sulfur from transmix blending will have a negligible impact on emissions from gasoline engines. Using EPA’s model for calculating emissions from vehicle fleets for a given year (MOBILE 6.2.03), EPA estimates that blending 0.25 volume percent transmix in gasoline would change emissions of various pollutants by only ¥0.2 to 0.3 percent. EPA believes that the effect of blending transmix in gasoline at relatively low percentages will have a similarly small effect on other complex model parameters, such that the consequent effect on gasoline emissions will also be negligible. Since gasoline toxics emissions are primarily affected by benzene, and the distillate fuel portion of transmix typically contains no benzene, transmix-blended gasoline is not expected to produce any more toxics than gasoline which does not PO 00000 Frm 00047 Fmt 4702 Sfmt 4702 contain transmix. Similarly, since evaporative emissions are primarily affected by RVP, and the distillate fuel portion of transmix has a much lower RVP than gasoline, volatile emissions from transmix-blended gasoline are not expected to be any greater than volatile emissions from gasoline which does not contain transmix. EPA is aware that the physical properties of gasoline and transmix can vary due to a variety of factors, which affect the percentage of transmix that can be blended into gasoline, without causing the endpoint of the transmixblended gasoline to exceed 437 degrees Fahrenheit. For example, gasoline that is produced for use during colder winter months often has an endpoint which is lower than the endpoint of gasoline produced during warmer summer months. Similarly, reformulated gasoline often has an endpoint which is lower than the endpoint of conventional gasoline produced during the same time of the year. Gasoline which has a relatively low endpoint compared to the ASTM standard can be blended with a greater percentage of distillate fuel without causing the endpoint of the transmix-blended gasoline to exceed 437 degrees Fahrenheit. Additionally, the properties of the transmix itself can vary widely due to the practices of the pipeline or terminal that produced the transmix. If transmix contains a relatively high percentage of gasoline, a relatively greater percentage of transmix can be blended into gasoline without causing the endpoint of the transmixblended gasoline to exceed 437 degrees Fahrenheit, since the transmix itself is already mostly composed of gasoline. Alternatively, if transmix contains a relatively high percentage of distillate fuel, the percentage of transmix that can be blended into gasoline without causing the endpoint of the transmixblended gasoline to exceed 437 degrees Fahrenheit is relatively low. EPA is not including any requirements in this proposed rule to list additional information on product transfer documents identifying gasoline or transmix properties. However, as described below, EPA is proposing that transmix blenders maintain a quality assurance program. EPA also understands that distillate fuel can potentially be blended more than once into the same volume of gasoline through transmix blending and other normal pipeline operations. Blending transmix multiple times into the same volume of gasoline can cause an excessive cumulative percentage of transmix to be blended into the gasoline, and cause the endpoint of the transmix-blended gasoline to exceed E:\FR\FM\02JNP1.SGM 02JNP1 Federal Register / Vol. 71, No. 106 / Friday, June 2, 2006 / Proposed Rules 437 degrees Fahrenheit. For example, a pipeline or terminal may blend transmix into gasoline, then send the gasoline to another pipeline or terminal which may blend transmix into the gasoline a second time. Similarly, as part of normal pipeline operation, pipeline operators may cut an interface between adjacent volumes of gasoline and distillate fuel directly into the gasoline volume. Cutting distillate fuel directly into gasoline has an effect on gasoline properties similar to the effect of blending transmix directly into the gasoline (gasoline endpoint increases and octane decreases). A downstream pipeline or terminal could then subsequently blend transmix into the same volume of gasoline which already contains distillate fuel from the interface cut. EPA is not including any requirements in this proposed rule to list any additional information on product transfer documents identifying whether gasoline has been blended with transmix or any distillate fuel. EPA believes that the requirement that gasoline produced by transmix blenders meet the 437 degree Fahrenheit endpoint standard will prevent any potentially deleterious effects from successive transmix blending. However, as described below, EPA is proposing that transmix blenders maintain a quality assurance program designed to ensure compliance with the endpoint standard. This proposed rule requires transmix blenders to maintain a quality assurance program that will ensure that the endpoint of transmix-blended gasoline does not exceed 437 degrees Fahrenheit, and that the transmix-blended gasoline will comply with the downstream standards for conventional or reformulated gasoline. As a part of this quality assurance program, transmix blenders must either sample and test transmix-blended gasoline at certain frequencies to determine the end-point of the gasoline, or submit a petition to EPA documenting how their quality assurance program ensures that the endpoint of their transmix-blended gasoline will not exceed 437 degrees Fahrenheit, and that the transmixblended gasoline meets all EPA downstream standards for conventional or reformulated gasoline. cchase on PROD1PC60 with PROPOSALS III. Administrative Requirements A. Executive Order 12866: Regulatory Planning and Review Under Executive Order 12866, (58 FR 51735 (October 4, 1993)) the Agency must determine whether the regulatory action is ‘‘significant’’ and therefore subject to OMB review and the VerDate Aug<31>2005 17:22 Jun 01, 2006 Jkt 208001 requirements of the Executive Order. The Order defines ‘‘significant regulatory action’’ as one that is likely to result in a rule that may: (1) Have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or tribal governments or communities; (2) Create a serious inconsistency or otherwise interfere with an action taken or planned by another agency; (3) Materially alter the budgetary impact of entitlements, grants, user fees, or loan programs or the rights and obligations of recipients thereof; or (4) Raise novel legal or policy issues arising out of legal mandates, the President’s priorities, or the principles set forth in the Executive Order.’’ It has been determined that this proposed rule does not satisfy the criteria stated above. As a result, this rule is not a ‘‘significant regulatory action’’ under the terms of Executive Order 12866 and is therefore not subject to OMB review. It would not have an annual effect on the economy of $100 million or more and is not expected to have any adverse economic effects as described in the Order. This proposed rule does not raise issues of consistency with the actions taken or planned by other agencies, would not materially alter the cited budgetary impacts, and does not raise any novel legal or policy issues as defined in the Order. B. Paperwork Reduction Act The modifications to the RFG information collection requirements in this rule have been 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 Request (ICR) document prepared by EPA has been assigned EPA ICR number 1591.21, OMB control number 2060–0277. This proposed rule addresses certain adverse impacts on refiners and importers of RBOB under the current rule and provides these refiners and importers with additional flexibility to comply with the regulations. The flexibility afforded under this rule is optional. Modest information collection requirements in the form gasoline surveys of oxygenate blending facilities are required for those parties who avail themselves of the flexibility provided in this rule. It is estimated that refiners and importers who choose this option will save, at a minimum, half of the cost they would incur if they complied with the existing QA requirements. PO 00000 Frm 00048 Fmt 4702 Sfmt 4702 32025 The estimated total hourly burden per respondent for the gasoline surveys is 20 hours. The estimated total hourly burden for all respondents is 700 hours (35 respondents maximum). The estimated hourly cost is estimated to be $71 per hour. The total estimated cost per respondent for the gasoline surveys is $1,420. The total estimated cost for all respondents is $49,700. In addition, the gasoline survey requirement is estimated to require purchase of services costs to industry of approximately $220,000, assuming that refiners and importers in all potentially affected RFG areas choose the compliance option under this rule. This rule would provide flexibility for transmix processors and transmix blenders to produce gasoline under certain circumstances without having to meet all of EPA’s standards for refiners. Transmix processors would be allowed to recover gasoline from transmix that does not need to be included in their compliance calculations, under certain circumstances. Transmix blenders would be provided with the additional flexibility to blend transmix at any rate and at any location, provided the endpoint of their transmix-blended gasoline does not exceed 437 degrees Fahrenheit. However, in order to ensure the endpoint of the transmix-blended gasoline does not exceed 437 degrees, transmix blenders would be required to either test every batch of transmixblended gasoline or submit a petition to EPA documenting that they maintain an oversight program that will prevent the endpoint of transmix-blended gasoline from exceeding 437 degrees. This proposed rule would codify existing practices designed to ensure that products transported by pipelines meet existing downstream standards. EPA estimates that approximately 25 transmix blenders will submit one-time petitions for approval of their quality testing programs. One transmix blender estimated that they would need 1–2 person-weeks to prepare a petition for EPA approval. For calculating the burden and cost of this rule, EPA has estimated that the average labor cost would be $71/hour, and that each petition would take 2 person-weeks (80 hours) to prepare. Multiplying the average labor cost by the total time required to prepare each petition (80 hours) by the total number of petitions (25) results in a total respondent cost of $142,000. The information under this rule will be collected by EPA’s Transportation and Regional Programs Division, Office of Transportation and Air Quality, Office of Air and Radiation (OAR), and by EPA’s Air Enforcement Division, E:\FR\FM\02JNP1.SGM 02JNP1 32026 Federal Register / Vol. 71, No. 106 / Friday, June 2, 2006 / Proposed Rules cchase on PROD1PC60 with PROPOSALS Office of Regulatory Enforcement, Office of Enforcement and Compliance Assurance (OECA). The information collected will be used by EPA to evaluate compliance with the requirements under the RFG and antidumping programs, and gasoline sulfur program. This oversight by EPA is necessary to ensure attainment of the air quality goals of the RFG and antidumping programs, and gasoline sulfur program. Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and systems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information. 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 in 40 CFR 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 proposed rule. C. Regulatory Flexibility Act The Regulatory Flexibility Act (RFA) generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute unless the agency certifies that the rule 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 proposed rule on small entities, small entity is defined as: (1) A small business as defined by the Small Business Administration (SBA) regulations at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city, county, town, VerDate Aug<31>2005 17:22 Jun 01, 2006 Jkt 208001 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 proposed rule on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. In determining whether a rule has a significant economic impact on a substantial number of small entities, the impact of concern is any significant adverse economic impact on small entities, since the primary purpose of the regulatory flexibility analyses is to identify and address regulatory alternatives ‘‘which minimize any significant economic impact of the rule on small entities.’’ 5 U.S.C. 603 and 604. Thus, an agency may certify that a rule will not have a significant economic impact on a substantial number of small entities if the rule relieves regulatory burden, or otherwise has a positive economic effect on all of the small entities subject to the rule. This proposed rule will not have any adverse economic impact on small entities. This proposed rule would codify existing guidance for the RFG and antidumping regulations, and establish provisions in the gasoline sulfur regulations (65 FR 6698, February 10, 2000) that allow transmix processors and transmix blenders more flexibility for compliance. The proposed rule would establish gasoline sulfur standards for transmix processors and blenders that are consistent with the sulfur standards for other entities, such as pipelines and terminals, that are downstream of refineries in the gasoline distribution system, and would clarify the requirements for transmix processors under the Mobile Source Air Toxics program. This proposed rule would codify existing practices designed to ensure that products transported by pipelines meet existing downstream standards. This proposed rule would also provide refiners and importers with an alternative compliance option for fulfilling a requirement to conduct downstream sampling and testing at oxygenate blender facilities. We have, therefore, concluded that this proposed rule would relieve regulatory burden for all small entities subject to the RFG regulations. We continue to be interested in the potential impacts of the proposed rule on small entities and welcome comments on issues related to such impacts. PO 00000 Frm 00049 Fmt 4702 Sfmt 4702 D. Unfunded Mandates Reform Act Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public Law 104–4, establishes requirements for Federal agencies to assess the effects of their regulatory actions on State, local, and tribal governments and the private sector. Under section 202 of the UMRA, EPA generally must prepare a written statement, including a cost-benefit analysis, for proposed and final rules with ‘‘Federal mandates’’ that may result in expenditures to State, local, and tribal governments, in the aggregate, or to the private sector, of $100 million or more in any one year. Before promulgating an EPA rule for which a written statement is needed, section 205 of the UMRA generally requires EPA to identify and consider a reasonable number of regulatory alternatives and adopt the least costly, most costeffective or least burdensome alternative that achieves the objectives of the rule. The provisions of section 205 do not apply when they are inconsistent with applicable law. Moreover, section 205 allows EPA to adopt an alternative other than the least costly, most cost-effective or least burdensome alternative if the Administrator publishes with the final rule an explanation why that alternative was not adopted. Before EPA establishes any regulatory requirements that may significantly or uniquely affect small governments, including tribal governments, it must have developed under section 203 of the UMRA a small government agency plan. The plan must provide for notifying potentially affected small governments, enabling officials of affected small governments to have meaningful and timely input in the development of EPA regulatory proposals with significant Federal intergovernmental mandates, and informing, educating, and advising small governments on compliance with the regulatory requirements. This proposed rule contains no Federal mandates (under the regulatory provisions of Title II of the UMRA) for State, local or tribal governments or the private sector that would result in expenditures of $100 million or more. This proposed rule provides refiners and importers of gasoline with additional flexibility in complying with regulatory requirements. As a result, this proposed rule would have the overall effect of reducing the burden of the RFG regulations on these regulated parties. This proposed rule would also codify existing practices designed to ensure that products transported by pipelines meet existing downstream standards. Therefore, the requirements E:\FR\FM\02JNP1.SGM 02JNP1 Federal Register / Vol. 71, No. 106 / Friday, June 2, 2006 / Proposed Rules of the Unfunded Mandates Act do not apply to this action. cchase on PROD1PC60 with PROPOSALS E. Executive Order 13132: Federalism Executive Order 13132, entitled ‘‘Federalism’’ (64 FR 43255, August 10, 1999), requires EPA to develop an accountable process to ensure ‘‘meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.’’ ‘‘Policies that have federalism implications’’ is defined in the Executive Order to include regulations that have ‘‘substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.’’ This proposed rule does not have federalism implications. It would not have substantial direct effects on the States, on the relationship between the National Government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132. This proposed rule would provide refiners and importers of gasoline with additional flexibility in complying with regulatory requirements. This proposed rule would also codify existing practices designed to ensure that products transported by pipelines meet existing downstream standards. The requirements of this proposed rule would be enforced by the Federal Government at the national level. Thus, Executive Order 13132 does not apply to this rule. F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments Executive Order 13175, entitled ‘‘Consultation and Coordination with Indian Tribal Governments’’ (65 FR 67249, November 6, 2000), requires EPA to develop an accountable process to ensure ‘‘meaningful and timely input by tribal officials in the development of regulatory policies that have tribal implications.’’ ‘‘Policies that have tribal implications’’ is defined in the Executive Order to include regulations that have ‘‘substantial direct effects on one or more Indian tribes, on the relationship between the Federal Government and the Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes.’’ VerDate Aug<31>2005 17:22 Jun 01, 2006 Jkt 208001 This proposed rule does not have tribal implications. It would not have substantial direct effects on tribal governments, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified in Executive Order 13175. This rule would apply to gasoline refiners and importers of gasoline. This action contains certain modifications to the federal requirements for RFG, and would not impose any enforceable duties on communities of Indian tribal governments. Thus, Executive Order 13175 does not apply to this rule. G. Executive Order 13045: Protection of Children From Environmental Health and Safety Risks Executive Order 13045: ‘‘Protection of Children from Environmental Health Risks and Safety Risks’’ (62 FR 19885, April 23, 1997) applies to any rule that: (1) Is determined to be ‘‘economically significant’’ as defined under Executive Order 12866, and (2) concerns an environmental health or safety risk that EPA has reason to believe may have a disproportionate effect on children. If the regulatory action meets both criteria, the Agency must evaluate the environmental health or safety effects of the planned rule on children, and explain why the planned regulation is preferable to other potentially effective and reasonably feasible alternatives considered by the Agency. EPA interprets Executive Order 13045 as applying only to those regulatory actions that are based on health or safety risks, such that the analysis required under the Order has the potential to influence the regulation. This proposed rule is not subject to Executive Order 13045 because it is not economically significant and does not establish an environmental standard intended to mitigate health or safety risks. H. Executive Order 13211: Acts That Significantly Affect Energy Supply, Distribution, or Use This proposed rule would not be an economically ‘‘significant energy action’’ as defined in Executive Order 13211, ‘‘Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use’’ (66 FR 28355 (May 22, 2001)) because it would not have a significant adverse effect on the supply, distribution, or use of energy. This PO 00000 Frm 00050 Fmt 4702 Sfmt 4702 32027 proposed rule will provide refiners and importers of gasoline with additional flexibility in complying with regulatory requirements. This proposed rule would also codify existing practices designed to ensure that products transported by pipelines meet existing downstream standards. As a result, this proposed rule may have a positive effect on gasoline supplies. 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, section 12(d) (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 standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies. The NTTAA directs EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable voluntary consensus standards. This proposed rule does not establish new technical standards within the meaning of the NTTAA. Therefore, EPA did not consider the use of any voluntary consensus standards. IV. Statutory Provisions and Legal Authority The statutory authority for the actions in this proposed rule comes from sections 211 and 301(a) of the CAA.

Regulation of Fuel and Fuel Additives: Refiner and Importer
Quality Assurance Requirements for Downstream Oxygenate Blending and
Requirements for Pipeline Interface

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of proposed rulemaking.

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

SUMMARY: This proposed rule would amend the reformulated gasoline (RFG)
regulations to allow refiners and importers of reformulated gasoline
blendstock for oxygenate blending, or RBOB, the option to use an
alternative method of fulfilling a regulatory requirement to conduct
quality assurance sampling and testing at downstream oxygenate blending
facilities. This alternative method consists of a comprehensive program
of quality assurance sampling and testing that would cover all
terminals that blend oxygenate with RBOB in a specified reformulated
gasoline covered area. The program would be carried out by an
independent surveyor funded by industry. The program would be conducted
pursuant to a survey plan, approved by EPA, that is calculated to
achieve the same objectives as the current regulatory quality assurance
requirement.
This proposed rule also would largely codify existing guidance for
compliance by parties that handle pipeline interface with requirements
for gasoline content standards, recordkeeping, sampling and testing.
The proposed rule also contains new provisions which would provide
additional flexibility to these regulated parties. The proposed rule
would also establish gasoline sulfur standards for transmix processors
and blenders that are consistent with the sulfur standards for other
entities, such as pipelines and terminals, that are downstream of
refineries in the gasoline distribution system, and would clarify the
requirements for transmix processors under the Mobile Source Air Toxics
program.

I. Refiner and Importer Quality Assurance Requirements for Downstream
Oxygenate Blending

A. Background

The RFG regulations currently require RFG to contain a minimum of
2.0 weight percent oxygen. 40 CFR 80.41. To fulfill this requirement,
oxygenate is added either at the refinery before the gasoline is
certified by the refiner as meeting RFG requirements, or it is added
downstream from the refinery at an oxygenate blending facility. As
discussed in more detail below, refiners often wish to require that
more than the minimum amount of oxygenate be added downstream in order
to include the additional oxygenate in their emissions performance
compliance calculations. Although Congress recently removed the oxygen
requirement for RFG in the Clean Air Act,\1\ we believe many refiners
and importers may wish to continue to include oxygenate added
downstream in their emissions compliance calculations. Under the
current regulations, refiners must conduct a program of quality
assurance testing at the downstream oxygenate blending facility in
order to include the oxygenate in their compliance calculations. This
proposed rule would provide an alternative QA requirement for these
refiners and importers.
---------------------------------------------------------------------------

\1\ 1 Energy Policy Act of 2005, Pub. L. 109-58 (HR6), section
1504(a), 119 STAT 594, 1076-1077(2005). In accordance with the
Energy Policy Act, EPA has issued a rule amending the RFG
regulations for California to remove the 2.0 weight percent oxygen
standard (71 FR 8965 (February 22, 2006)), and has proposed a
similar rule that would be applicable in the rest of the country (71
FR 9070 (February 22, 2006)).
---------------------------------------------------------------------------

Under the current regulations, when oxygenate is to be added to
produce RFG at a downstream oxygenate blending facility, refiners
produce a product called reformulated gasoline blendstock for oxygenate
blending, or RBOB. RBOB is certified by the refiner, or by an importer
who imports RBOB, as complying with all of the RFG requirements except
the minimum 2.0 weight percent oxygen requirement. The oxygenate
blender is responsible for complying with the oxygen requirement when
the oxygenate is added to the RBOB to produce RFG at the oxygenate
blending facility.
Various oxygenates may be used to fulfill the oxygen requirement.
Some oxygenates, such as methyl tertiary butyl ether, or MTBE,
typically are added at the refinery. However, some oxygenates, such as
ethanol, have a propensity to attract water, and, as a result, cannot
be added at the refinery, particularly where the finished gasoline will
be traveling through a pipeline on its way to terminals and retail
gasoline stations. As a result, RFG containing ethanol is typically
produced by blending the ethanol with RBOB at a blending facility
downstream from the refinery that produced the RBOB.
Refiners and importers of RBOB are required to calculate compliance
with the RFG emissions performance standards for VOC, NOX
and toxics by sampling and testing a hand blended mixture of the RBOB
and the type and amount of oxygenate that the refiner or importer of
the RBOB designates must be added downstream. The type and amount of
oxygenate to be added downstream must be indicated on the product
transfer documents that accompany the gasoline when it is transferred
to the downstream oxygenate blender. The oxygenate blender is required
to add the type and amount of oxygenate designated on the product
transfer documents.
Under the current regulations, RBOB refiners and importers can
designate either a specific type and specific amount of oxygenate to be
added downstream, or they can designate one of two generic categories
of RBOB: ``any-oxygenate'' RBOB or ``ether-only'' RBOB. 40 CFR
80.69(a)(8). Where the RBOB is designated as any-oxygenate RBOB, the
refiner or importer must assume for purposes of its handblend that 2.0
weight percent ethanol will be added downstream. The downstream
oxygenate blender may add any type of legal \2\ oxygenate, to any-
oxygenate RBOB in an amount sufficient to meet the minimum 2.0 weight
percent requirement. Where the RBOB is designated as ether-only RBOB,
the refiner or importer must assume for purposes of its handblend that
2.0 weight percent MTBE will be added downstream. The oxygenate blender
may add any legal ether oxygenate to ether-only RBOB in an amount
sufficient to meet the minimum 2.0 weight percent requirement.
---------------------------------------------------------------------------

\2\ Oxygenates that are allowed under EPA's ``substantially
similar'' rule and any section 211(f) waiver that may apply.
---------------------------------------------------------------------------

Where a specific type and amount of oxygenate is designated for the
RBOB rather than one of the two generic designations, the regulations
require the refiner or importer to conduct downstream oversight quality
assurance (QA) sampling and testing of the downstream oxygenate
blending facility. 40 CFR 80.69(a)(7). This is to ensure that the
specific type and amount of oxygenate that is designated, which
typically is greater than the 2.0 weight percent requirement, in fact
is added to the RBOB by the oxygenate blender. In addition, the refiner
or importer must have a contract with the oxygenate blender which
requires the blender to comply with the blending procedures specified
by the RBOB refiner or importer and allows the refiner or

[[Page 32018]]

importer to conduct the required QA sampling and testing. 40 CFR
80.69(a)(6). If the refiner or importer does not meet the contractual
and quality assurance requirements and does not designate its RBOB as
ether-only or any-oxygenate, the refiner or importer must assume for
purposes of its handblend that 4.0 volume percent ethanol will be added
to the RBOB downstream.

B. Need for Action

Recently, the states of New York and Connecticut promulgated state
laws banning the use of MTBE in gasoline sold in these states. As a
result, many refiners and importers that historically produced or
imported RFG containing MTBE for the NY/CT RFG area currently produce
or import RBOB for ethanol blending. Refiners in this area have
indicated that, due to the complex gasoline marketplace in New York and
Connecticut, it is extremely difficult, if not impossible, to track
RBOB from the refinery where it is produced to the terminal where it is
blended with ethanol in order to fulfill the downstream QA sampling and
testing requirement. As a result, under the current regulations,
refiners in the NY/CT RFG area are effectively precluded from producing
an RBOB which requires a specific type and amount of oxygenate, such as
10 volume percent ethanol, and instead must produce a generic any-
oxygenate RBOB, which does not require the refiner to conduct
downstream QA testing at the ethanol blender facility.
As discussed above, for purposes of calculating compliance with RFG
emissions performance standards, these refiners may then only include
in their handblends ethanol in an amount which would result in gasoline
having 2.0 weight percent ethanol (approximately 5.7 volume percent
ethanol.) Some refiners have indicated that they will need to produce
RBOB requiring 10 volume percent ethanol, which would allow them to
include 10 volume percent ethanol for purposes of compliance
calculations, in order to meet emissions performance standards. As a
result, these refiners have asked EPA to allow use of an alternative
method of meeting the downstream QA sampling and testing requirement.
For the reasons discussed below, we believe it is appropriate to
provide refiners and importers who produce or import RBOB for the NY/CT
RFG area with an alternative means of meeting the QA sampling and
testing requirement. We also believe it is appropriate to provide this
alternative to refiners and importers who produce or import gasoline
RBOB for other RFG areas. As a result, this proposed rule would amend
the RFG regulations to provide an alternative QA sampling and testing
option which will be available to any RBOB refiner or importer in any
RFG covered area. As indicated above, we believe that providing this
alternative QA requirement would be appropriate even after the 2.0
weight percent minimum oxygen standard is removed.

C. This Action

This proposal would provide RBOB refiners and importers the option
to comply with an alternative QA requirement which consists of a
program of sampling and testing designed to provide oversight of all
terminals that blend ethanol with RBOB for use in a specified RFG
covered area. Under this option, a refiner or importer would need to
either arrange to have an independent surveyor conduct a program of
compliance surveys, or participate in the funding of an organization
which arranges to have independent surveyor conduct a program of
compliance surveys. In either event, compliance surveys would need to
be carried out by an independent surveyor pursuant to a survey plan
calculated to achieve the same QA objectives as the current regulatory
requirement. A detailed survey plan would be submitted to EPA for
approval by September 1st of the year preceding the annual averaging
period in which the alternative QA sampling and testing program would
be implemented. The survey plan would include a methodology for
determining when the survey samples will be collected, the location of
the retail outlets where the samples will be collected, the number of
samples to be included in the survey, and any other elements that EPA
determines are necessary to achieve the same level of quality assurance
as the current QA requirement.
Under this alternative QA option, the independent surveyor would be
required to obtain samples at retail stations in the RFG covered area
in accordance with the survey plan and have the samples tested for type
and amount of oxygenate. The sampling and testing conducted under this
alternative QA option would be required to be done in accordance with
the provisions in Sec. Sec. 80.8 and 80.46. The surveyor would obtain
from the retail outlet the product transfer documents associated with
the gasoline, which will provide the surveyor with information
regarding the type and amount of oxygenate that the gasoline is
supposed to contain, and the terminal that conducted the oxygenate
blending. The surveyor would be required to notify EPA of any instance
where the product transfer documents do not contain such information.
If the test results show that the gasoline does not contain the type
and/or the minimum amount of oxygenate indicated on the product
transfer documents, the surveyor would be required to ask the terminal
determined to have supplied the gasoline to produce documentation of
the blending instructions from the refiner or importer of the RBOB. The
surveyor would be required to notify EPA of any instances where the
refiner's or importer's blending instructions indicate that the
oxygenate blender did not add the type or minimum amount of oxygenate
designated for the RBOB by the refinery or importer. The surveyor would
be required to submit to EPA a report which includes the information
and data collected during the survey, and to maintain records
associated with the surveys for five years.
This proposed rule would require each refiner and importer who
chooses to comply with the alternative QA requirement to take all
reasonable steps to ensure that parties downstream from the refiner or
importer cooperate with the program by allowing the independent
surveyor to collect samples, and by providing to the independent
surveyor copies of product transfer documents and other information
regarding the source of any gasoline received, the destination of any
gasoline distributed, the oxygenate blending instructions for RBOB, and
the rate the oxygenate was blended. In partial satisfaction of the
``reasonable steps'' requirement, the rule would require the refiner or
importer to include such a requirement in contractual agreements with
its branded downstream facilities.
In addition, this proposed rule would require parties downstream
from a refiner or importer that complies with the alternative QA
requirement to include on product transfer documents the type and
amount of oxygenate contained in the gasoline and identification of the
oxygenate blending terminal that blended the gasoline. This proposed
rule would require that the survey plan include a process for notifying
all oxygenate blending terminals and other downstream parties in the
affected area of the product transfer documentation requirement. Where
a downstream party fails to receive notice of the product transfer
requirement, the party would be required to begin complying with the

[[Page 32019]]

product transfer requirement upon notification by EPA.
We believe that use of this QA compliance alternative would result
in oversight sampling and testing that is equivalent to the current
regulatory QA requirement, and, in fact, may result in significantly
superior QA oversight since the sampling and testing would be conducted
by an independent surveyor in accordance with a comprehensive plan
approved by EPA, rather than by individual refiners and importers. This
rule would not have any adverse environmental impact, and would provide
refiners and importers with additional flexibility in complying with
the regulations. As a result, while this rulemaking was initiated in
response to the compliance issues raised by refiners in the NY/CT area,
we believe it is appropriate to provide this compliance alternative to
refiners and importers supplying any RFG covered area. The rule,
therefore, would provide this QA compliance alternative to any RBOB
refiner or importer in any RFG area who either arranges to have an
independent surveyor conduct a program of compliance surveys, or who
participates in the funding of an organization that arranges to have an
independent surveyor conduct a program of compliance surveys, in
accordance with the provisions in this proposed rule.
Compliance with this QA alternative would be optional. Refiners and
importers may choose to comply with the existing QA requirement and not
participate in a survey program. Refiners and importers who supply more
than one RFG area may choose to participate in the survey program for
one RFG area and comply with the existing QA requirement for another
RFG area.
This proposed rule would add a new paragraph (a)(11) to 40 CFR
80.69, which contains the current QA requirement. This proposed rule
also would amend Sec. 80.77 to require parties to include on product
transfer documents the information required under Sec. 80.69(a)(11) as
described above.

II. Requirements for Pipeline Interface

A. Background

Refined petroleum products that are transported by pipeline
normally are pumped sequentially, as a continuous flow through the
pipeline. As a result, some amount of mixing of adjacent product types
normally occurs. The product in a pipeline between two adjacent volumes
of petroleum product consists of a mixture of the two adjacent volumes
and is called ``interface.'' Generally, interface is blended into the
two adjoining products that created the interface. For example, half of
the interface between premium and regular gasoline is blended into the
premium gasoline and half into the regular gasoline (called a ``fifty
percent cut'' or a ``mid-point cut.'') However, certain product types,
such as jet fuel, are not mixed with any other product type, and all of
the interface that contains jet fuel is blended into the other product
(called a ``clean cut.'')
Where interface consists of a mixture of finished fuels that cannot
be cut with adjoining product so as to produce a product that meets the
specifications for a fuel that can be used or sold without further
processing, the interface is called ``transmix''. Transmix is not
blended into either of the two adjacent products transported by the
pipeline, but is diverted by the pipeline as a distinct product into a
separate storage tank. Transmix is generally transported via tank
truck, pipeline or barge to a facility designed to separate the
transmix into its fuel components. For example, where the transmix
consists of gasoline and distillate fuel, the transmix may be
transported to a ``transmix processing'' facility where the gasoline
portion is separated from the distillate fuel. At locations where it is
either relatively expensive or inconvenient to transport transmix to a
transmix processing facility for separation, the transmix is sometimes
blended into gasoline in very small amounts, typically around 0.25
volume percent of the gasoline.
The reformulated gasoline (RFG) and anti-dumping requirements apply
at any facility where gasoline is produced. See 40 CFR 80.2(h) and (i),
80.65(a), and 80.101. Gasoline most commonly is produced by processing
crude oil at refineries, but it is also produced by other processes,
such as combining blendstocks or adding blendstocks to finished
gasoline. Gasoline is also produced when transmix is blended into
gasoline, or when transmix is separated into gasoline and distillate
fuel. Transmix blending is similar to adding blendstock to gasoline
where the addition of the transmix, like blendstock, may change the
properties of the gasoline. Similarly, the process of separating
gasoline and distillate fuel may result in gasoline with different
properties than the gasoline as originally certified by the refinery.
Transmix processors and transmix blenders are refiners under the RFG/
anti-dumping regulations, but EPA has historically provided transmix
processors and transmix blenders flexibility in complying with the
refiner requirements. This proposed rule would codify some of the
existing practices into EPA regulations, and would also include
modifications reflecting EPA experience.

B. 1997 Notice of Proposed Rulemaking

On July 11, 1997, EPA proposed to add a new Sec. 80.84 to the RFG/
anti-dumping regulations at 40 CFR Part 80 to clarify the manner in
which interface, including transmix, would be treated under the RFG/
anti-dumping regulations. The NPRM proposed requirements for
designating different combinations of gasoline in interface. The NPRM
also proposed requirements for transmix processors and transmix
blenders that produce either RFG or conventional gasoline.
The NPRM proposed to allow parties to blend transmix into
conventional gasoline provided that the transmix resulted from normal
pipeline operations, and either there was no means of transporting the
transmix to a transmix processor via pipeline or water, or there was an
historical practice of blending transmix at the facility before 1995.
The rate of transmix blending was limited to the greater of 0.25 volume
percent or the demonstrated blending rate in 1994. The NPRM proposed to
allow transmix to be blended into RFG provided that the transmix
resulted from normal pipeline operations, there was no means of
transporting the transmix to a transmix processing facility via
pipeline or water, and the party was unable to blend the transmix into
conventional gasoline. The rate of transmix blending into RFG was
limited to a maximum of 0.25 volume percent. The NPRM also proposed
requiring transmix blenders to carry out a program of periodically
sampling and testing of the RFG subsequent to transmix blending to
ensure that the downstream standards were met.
The NPRM proposed to require transmix processors who designate the
gasoline produced from the transmix (such gasoline is one type of
transmix gasoline product, or TGP) as conventional gasoline to exclude
the TGP from anti-dumping compliance calculations for the transmix
processing facility, but to include any blendstocks added to the TGP
since such blendstocks would not previously have been included in any
refinery's compliance calculations. The NPRM proposed to require
transmix processors who designate the gasoline produced from transmix
as RFG to include the TGP, as well as any blendstocks used, in the RFG
compliance calculations for the transmix processing facility to

[[Page 32020]]

ensure that the gasoline produced using the transmix meets all RFG
standards.
Parties have been processing and blending transmix in accordance
with EPA guidance which describes similar treatment of interface and
transmix as that outlined in the July 11, 1997 NPRM. (See Reformulated
Gasoline and Anti-dumping Questions and Answers (November 12, 1996)).
Our experience since the guidance was issued indicates that the
approach taken in the guidance is mostly appropriate, but that some
revisions are warranted. EPA is also aware, from recent discussions
with several pipeline operators, that volumes of transmix may increase
as pipelines begin transporting ultra-low sulfur diesel fuel. EPA had
anticipated that transporting ultra-low sulfur diesel would require
greater volumes of diesel to be cut as interface into other higher-
sulfur distillate fuels such as heating oil and jet fuel. However, some
pipelines have indicated they intend to change their product sequencing
by transporting volumes of ultra-low sulfur diesel between volumes of
gasoline, in order to minimize sulfur contamination of the ultra-low
sulfur diesel. This change would increase the number of gasoline/diesel
interfaces cut to transmix, and increase the overall volume of
transmix. Pipeline operators have also indicated that transporting
ultra-low sulfur diesel fuel will cause them to generate transmix at
locations where they have not historically generated transmix.
In this proposed rule, we are including the provisions in Sec.
80.84, which were previously proposed in the July 11, 1997 NPRM, with
certain changes made in response to the comments we received on the
NPRM, as discussed below. We believe it is appropriate to include in
this proposal the provisions in Sec. 80.84 given the length of time
since they were originally proposed, and to include changes made in
response to prior comments. We have also added several new provisions
in this proposal clarifying, and in some instances expanding, the
flexibilities available to transmix processors and transmix blenders
for complying with the RFG/antidumping regulations. This proposed rule
also includes modest recordkeeping requirements in Sec. Sec. 80.74 and
80.104 which would require parties that handle interface and transmix
to keep records verifying that the requirements of Sec. 80.84 were
met. In addition, this proposed rule includes provisions for transmix
processors and transmix blenders related to gasoline sulfur and air
toxics. This proposed rule only addresses gasoline produced by transmix
processors and transmix blenders. Distillate fuel produced by transmix
processors and transmix blenders is addressed in the diesel sulfur
regulations under 40 CFR part 80, subpart I.
EPA believes the flexibilities available in this proposed rule are
appropriate given the unique roles that transmix processors and
transmix blenders fill in the petroleum products distribution system.
Although transmix processors and transmix blenders are refiners under
EPA's regulations, almost all of the gasoline and distillate fuel they
produce is derived from fuel which has already been produced and
certified by an upstream refinery. Thus, this proposed rule would allow
transmix processors the flexibility to exclude from their antidumping
compliance calculations conventional gasoline that they recover
directly from transmix, since the conventional gasoline has already
been accounted for in the compliance calculations of an upstream
refinery. Similarly, this proposed rule would allow transmix processors
to only have to meet the downstream sulfur standards for gasoline they
recover directly from transmix, since the gasoline has already been
accounted for in the compliance calculations of an upstream refinery.
However, transmix processors must comply with all refiner standards at
each of their transmix processing facilities for any blendstocks they
add to gasoline. Lastly, this proposed rule would allow transmix
blenders to blend transmix into gasoline without restriction on
location or rate, provided the endpoint of the transmix-blended
gasoline does not exceed 437 degrees Fahrenheit, and that the gasoline
meets all applicable downstream standards.

C. Pipelines

This proposed rule includes designations for pipeline interface
that are consistent with the designations in EPA's current guidance and
the 1997 NPRM. The designations for pipeline interface are primarily
intended to ensure that pipelines cut their interfaces in a manner that
maintains the quality of any RFG or VOC-controlled gasoline transported
by a pipeline. For example, interfaces between volumes of RFG and
conventional gasoline should be cut into the conventional gasoline to
maintain the quality of the RFG. Regardless of gasoline product
designation, all gasoline containing interface must meet all downstream
standards, including but not limited to any standards and requirements
that apply downstream of the refinery in 40 CFR Part 80 and the Clean
Air Act.

D. Transmix Processors

1. Comments on the 1997 Notice of Proposed Rulemaking
EPA received a number of comments on the 1997 NPRM regarding
transmix processors. One commenter said that the definition of transmix
should be changed since transmix processors and transmix blenders
sometimes process or blend mixtures of fuels that were unintentionally
combined in tanks. Although such mixtures are similar in composition to
transmix, they do not fit the definition of transmix proposed in the
1997 NPRM, which specified that transmix must be generated in a
pipeline. EPA agrees that a product that in composition is similar to
transmix, and that is produced by unintentionally mixing gasoline and
distillate fuel in tanks, should be afforded the same treatment as
transmix product generated in a pipeline. EPA also understands that
transmix may include mixtures of gasoline and distillate fuel produced
through normal operational activities at pipelines and terminals, such
as draining tanks, or draining piping and hoses used to transfer
gasoline or distillate fuel to tanks or trucks, or from a safety relief
valve discharging to protect equipment from overpressuring. As a
result, Sec. 80.84(e) in this proposed rule specifically allows such
products to be covered under the transmix provisions.
EPA is aware that some transmix processors and transmix blenders
may also be adding feedstocks to their transmix that were not produced
from normal pipeline interface, or from inadvertently mixing gasoline
and distillate fuel in tanks, or through normal operational activities
at pipelines and terminals. Mixing other feedstocks in transmix prior
to processing may cause these other feedstocks to be inappropriately
accounted for under the antidumping regulations and gasoline sulfur
regulations, as discussed later. The flexibility provided in this rule
extends only to transmix composed of pipeline interface, mixtures of
gasoline and distillate fuel that were unintentionally combined in a
tank, and mixtures of gasoline and distillate fuel produced through
normal operational activities at pipelines and terminals. A transmix
processor or transmix blender who adds feedstocks derived from any
other sources to their transmix must comply with all the standards
applicable to a refiner under EPA's regulations for all the gasoline
they produce during a compliance period, including but not limited to
any standards and requirements in 40 CFR parts 79, 80 and

[[Page 32021]]

the Clean Air Act. Transmix processors that add feedstocks from any
other sources should also take extra care to be sure that they are
complying with Subtitle C of the Resource Conservation and Recovery Act
(RCRA), 42 U.S.C. 6921-6939(e), and any state provision authorized
pursuant to Section 3006 of RCRA, 42 U.S.C. 6926.
One commenter said that the 1997 NPRM should clarify that the
transmix processing requirements do not apply to transmix processed by
a crude oil refinery where the transmix is received into a crude or
other feedstock stream and is not separated before it is added to other
feedstocks. EPA believes that the regulations in this proposed rule are
clear in this regard, since they specifically apply to persons who
separate transmix at a transmix processing facility. The term
``transmix processing facility'' is defined as excluding refineries
that ``produce gasoline by processing crude oil''. Such refineries must
comply with all existing refiner requirements, and would not be
eligible to take advantage of the flexibilities available in this
proposed rule.
Some commenters said that they do not know the source of the
transmix and, therefore, would not know the original designation of the
gasoline portion of the transmix (e.g., RFG, conventional gasoline,
blendstocks). The commenters said that the transmix processor should
not be required to track and segregate transmix generated from
different types of gasoline or blendstocks. This proposed rule would
not require a transmix processor to track and segregate transmix.
However, Sec. 80.65 requires the transmix processor to designate the
gasoline portion (i.e., conventional gasoline, RFG, or RBOB) that is
separated from the distillate fuel.
One commenter said that, under previous guidance, EPA provided for
the exclusion of the transmix-based portion of conventional gasoline
from anti-dumping compliance calculations as an option, whereas in the
1997 NPRM, the exclusion would be mandatory. The commenter believes the
exclusion should be optional. Another commenter believes that transmix
processing improves the quality of the gasoline separated from transmix
by removing more heavy aromatics and sulfur compounds and improving
E300 distillation point, and therefore, TGP should be included in
compliance calculations for conventional gasoline to give credit for
the improvements. EPA agrees with the commenters, and this proposed
rule would modify the 1997 NPRM to allow the exclusion of the TGP from
anti-dumping compliance calculations to be optional, provided the TGP
meets all of the downstream standards for conventional gasoline.
However, in order to prevent transmix processors from selectively
including only high quality TPG batches in their compliance
calculations, while excluding those of low quality, transmix processors
must consistently include or exclude TGP in their compliance
calculations during each annual compliance period, with one exception.
The exception occurs if transmix contains gasoline blendstocks that
are derived from pipeline interface. EPA understands that some
pipelines transport gasoline blendstocks, and that these pipelines may
cut interfaces containing gasoline blendstock to a transmix tank. If a
transmix processor produces conventional gasoline from transmix
containing gasoline blendstocks and was allowed to exclude the TGP from
their anti-dumping compliance calculations, the finished conventional
gasoline would not be included in any refiner's anti-dumping compliance
calculations. Thus, under this proposal, if a transmix processor
produces conventional gasoline at a transmix processing facility from
transmix containing gasoline blendstocks derived from pipeline
interface, the transmix processor must consistently include all TGP
produced during a compliance period in their antidumping compliance
calculations for that transmix processing facility. As discussed
previously, if transmix processors add any feedstocks to their transmix
that were not produced from normal pipeline interface, or from
inadvertently mixing gasoline and distillate fuel in tanks, or through
normal operational activities at pipelines and terminals, they would
need to comply with all standards applicable to refiners under EPA's
regulations for all the gasoline they produce during a compliance
period. This proposed rule would also require any RFG or RBOB produced
by a transmix processor to be included in the RFG compliance
calculations for the transmix processing facility.
This proposed rule would also modify the 1997 NPRM by treating TGP
as a blendstock when the transmix processor mixes the TGP with other
blendstock(s) to produce conventional gasoline. In this situation, the
TGP would be included in compliance calculations for the resulting
conventional gasoline. We believe it is appropriate to treat TGP as a
blendstock rather than as a previously certified gasoline in this
situation, since the TGP is likely to have undergone changes as a
result of having been interfaced with another product and separated
through transmix processing. For example, one transmix processor
indicated that their TGP could not be directly sold as gasoline because
it does not meet standards for octane or Reid vapor pressure. This
approach is consistent with the approach taken in both the 1997 NPRM
and the Question and Answer guidance with regard to RFG, where TGP is
required to be included in compliance calculations when it is mixed
with blendstock to produce RFG.
Where TGP is sold as a blendstock, the transmix processor would be
required to exclude the TGP from compliance calculations, with one
exception. The exception is when the transmix processor sells the TGP
to an oxygenate blender as a blendstock which becomes conventional
gasoline solely upon the addition of an oxygenate, such as ethanol or
MTBE. In this circumstance, the transmix processor would need to
include the TGP in compliance calculations. This exception would not
apply if the TGP is combined with any other non-oxygenated blendstocks
to produce conventional gasoline. Thus, in order for a transmix
processor to properly account for any TGP sold as a blendstock in
compliance calculations for a transmix processing facility, the
transmix processor must clearly state on the TGP product transfer
documents whether or not the TGP may only be combined with an oxygenate
to produce conventional gasoline. This approach is consistent with the
anti-dumping regulations at Sec. 80.101(d)(3), which require
blendstocks that become conventional gasoline solely upon the addition
of an oxygenate to be included in anti-dumping compliance calculations
for the refiner that produced the blendstock.
Transmix processors also sometimes blend sub-octane TGP with
previously certified premium gasoline (PCG) to produce regular
gasoline. EPA is proposing that transmix processors which blend sub-
octane TGP with premium PCG to produce conventional gasoline must
include the TGP in compliance calculations for the transmix processing
facility, but may meet the sampling and testing requirements in one of
three ways. First, the transmix processor may directly measure the
properties of the TGP and treat each volume of TGP blended with PCG as
a separate batch for purposes of compliance calculations. As a second
alternative, the transmix processor may measure the volume and
properties of the PCG prior to blending with the TGP, then measure the
volume and properties of the gasoline subsequent to blending

[[Page 32022]]

with the TGP, and calculate the volume and properties of the TGP by
subtracting the volume and properties of the PCG from the volume and
properties of the gasoline subsequent to blending. As a third
alternative, the transmix processor may demonstrate compliance using
the procedures in Sec. 80.101(g)(9). Where TGP is mixed with
previously certified gasoline to produce RFG or RBOB, the transmix
processor must demonstrate compliance using the procedures in Sec.
80.65(i).
One commenter said that EPA should allow transmix processors to
blend oxygenates and other blendstocks into transmix-based conventional
gasoline to produce RFG. This proposed rule would address this comment
by allowing transmix processors to treat their TGP as a blendstock, and
combine the TGP with other blendstocks to produce either conventional
or reformulated gasoline. In this situation, the transmix processor
would be required to fulfill all the requirements and standards for RFG
that apply to a refiner.
2. Issues Not Addressed in the 1997 NPRM
a. Gasoline Sulfur. In the preamble to the gasoline sulfur
regulations, EPA indicated that the Agency would establish requirements
for transmix processors in a future rulemaking (65 FR 6800, February
10, 2000). Therefore, as part of this rulemaking, EPA is also including
proposed requirements for transmix processors and transmix blenders
under the gasoline sulfur regulations at 40 CFR part 80, subpart H.
As under the RFG/anti-dumping rule, transmix processors and
transmix blenders are refiners under the gasoline sulfur regulations.
As a result, transmix processors and transmix blenders are subject to
the refinery sulfur standards under Sec. 80.195 of the gasoline sulfur
regulations. However, for reasons discussed below, we believe it is
appropriate that such parties be held to the gasoline sulfur standards
applicable to downstream parties under Sec. Sec. 80.210 and 80.220 of
the gasoline sulfur regulations, and not be held to the more stringent
refinery standards in Sec. 80.195.
As indicated above, transmix processors generally do not control
their feedstock, but receive mixtures of products from upstream
refineries. The gasoline portion of transmix may be relatively high in
sulfur if it was originally produced by a small refiner, a refiner
producing gasoline for use in the Geographic Phase-in Area (GPA), or a
refiner who has been given a temporary hardship extension to produce
relatively high sulfur gasoline. As a result, holding transmix
processors to the downstream sulfur standards rather than the more
stringent refinery standards would provide transmix processors the
flexibility to recover gasoline originally produced by small refiners,
refiners of GPA gasoline, or temporary hardship refiners. To ensure
compliance with the applicable downstream sulfur standards, transmix
processors will be required to test any gasoline produced from transmix
for sulfur content.
Under this proposed rule, transmix processors who add blendstocks
not derived from transmix to their recovered gasoline would be required
to meet all of the requirements and standards that apply to refiners
under 40 CFR Part 80, subpart H, for such blendstocks. Where certain
requirements are met, the transmix processor may use sulfur test
results from the blendstock supplier for purposes of meeting the
sampling and testing requirements under the sulfur rule.
As mentioned previously, EPA has learned that some transmix
processors have added feedstocks to their transmix, before the transmix
is processed, that are not produced from pipeline interface, or from
mixtures of gasoline and distillate fuel unintentionally combined in a
tank, or from normal operations at pipelines and terminals. Under this
proposal, transmix processors that use these other feedstocks would
need to meet all EPA standards applicable to a refiner for all the
gasoline they produce during a compliance period, including the
refinery level sulfur standards in 40 CFR 80.195. These transmix
processors could not utilize the flexibilities in this rule because
they have chosen to use feedstocks that have not been previously
accounted for by a refinery in the production of gasoline. When the
transmix is processed, the previously compliant gasoline present in the
transmix and the other feedstocks both distill out of the transmix
together as a fungible product, and the transmix processor cannot
distinguish exactly which portion of the TGP was derived from
previously compliant gasoline and which was derived from other
feedstocks. Thus, EPA proposes limiting the flexibility allowed by this
proposed rule to gasoline produced from transmix, only if the transmix
was produced from pipeline interface, or from mixtures of gasoline and
distillate fuel that were unintentionally combined in a tank, or from
mixtures of gasoline and distillate fuel produced from normal
operational activities at pipelines and terminals. Transmix processors
who add any other material to their transmix would need to comply with
all EPA standards applicable to a refiner for all the gasoline they
produce during a compliance period, including the refinery level sulfur
standards in 40 CFR 80.195.
This proposed rule would, however, allow transmix processors that
produce gasoline from pipeline interface to meet the less stringent
downstream gasoline sulfur standards, even if the interface contains
small amounts of gasoline blendstocks that are transported via pipeline
as a normal part of pipeline operations. EPA believes it is appropriate
to allow transmix processors that produce gasoline from these interface
mixtures to meet the downstream sulfur standards because they do not
have the same level of control over their transmix as the transmix
processors that intentionally introduce other feedstocks into the
production process. Furthermore, because the volume of gasoline
blendstocks in the transmix will be relatively small and since the
gasoline will still have to meet downstream standards, EPA believes the
environmental consequences of allowing these transmix processors to
meet the less stringent downstream sulfur standard should be
negligible.
This proposed rule would add a new Sec. 80.213 to the gasoline
sulfur regulations. This section contains the additional requirements
for demonstrating compliance with the gasoline sulfur rule discussed
above for refiners who process or blend transmix in accordance with the
provisions in Sec. 80.84. EPA believes that the additional proposed
requirements for transmix processors and transmix blenders in Sec.
80.213 are necessary to maintain the flexibility of the current
practices regarding transmix, and will not result in any adverse
environmental consequences. This proposed rule would also add modest
recordkeeping requirements to Sec. 80.365 which require parties to
retain records of any sampling and testing required under Sec. 80.213.
b. Air Toxics. The mobile source air toxics (MSAT) rule (66 FR
17230, March 29, 2001) requires the annual average toxics performance
of a refinery's or importer's gasoline to be at least as clean as the
average of its gasoline during the three-year baseline period 1998-
2000. The MSAT requirements apply separately to RFG and to conventional
gasoline. MSAT compliance is determined from the same gasoline data
used by a refiner to determine its compliance with the RFG or anti-
dumping requirements. As a result, only gasoline which would be
included in the RFG or anti-dumping compliance determination of a
refiner is

[[Page 32023]]

included in the refiner's MSAT baseline and compliance determinations.
Most, if not all, transmix processors have unique individual MSAT
baselines. Under MSAT, those with unique individual MSAT baselines
(Sec. 80.915) are subject to their MSAT baseline up to their
associated MSAT baseline volume (Sec. 80.850). Gasoline production
above the MSAT baseline volume is subject to either the RFG toxics
performance standard (Sec. 80.41) or to the refiner's anti-dumping
standard (Sec. 80.91). Because these standards are equal to or less
stringent than the refiner's MSAT baseline, they offer some flexibility
to the refiner's overall compliance with its MSAT standard. Because
gasoline demand is increasing, EPA expects that this provision will
provide most refiners with some degree of MSAT compliance flexibility.
The MSAT rules also provide for limited credit and deficit carryover,
allowing refiners to weather slightly off years with better toxics
performance in an adjacent year (Sec. 80.815). Finally, because all
refiners are subject to MSAT standards which are typically more
stringent than the RFG toxics performance standard or their individual
anti-dumping standard, it is likely that the gasoline portion of the
transmix is also cleaner with respect to toxics performance than it was
during the baseline period 1998-2000, thus providing some immediate
flexibility to transmix processors and transmix blenders.
This action clarifies that any gasoline or blendstock a transmix
processor includes in their RFG or anti-dumping compliance
determination is also included in their MSAT compliance calculations.
Also, EPA has recently proposed to replace the existing MSAT
regulations with a standard that would limit the benzene content of
gasoline to an annual average of 0.62 percent by volume for most
refiners, beginning in 2011. See 71 FR 15803 (March 29, 2006). The
proposed toxics regulations would exempt transmix processors from the
new benzene standard for any gasoline they recover from transmix, but
require transmix processors to meet the standard for any blendstocks
they add to transmix.

E. Transmix Blenders

1. Comments on the 1997 Notice of Proposed Rulemaking

One commenter was concerned that the sampling and testing
procedures in the 1997 NPRM for blends of transmix and RFG, which would
be performed after blending the transmix, may not prevent the release
of noncompliant RFG in the distribution system. For reasons discussed
below, however, EPA believes that commercial standards limit transmix
blending to such small percentages, that blending transmix in RFG will
cause essentially no change in the emissions performance of the RFG.
This proposed rule would specifically require that all gasoline
produced by transmix blenders have an endpoint less than 437 degrees
Fahrenheit. As described below, as a practical matter, EPA believes
that this endpoint standard will effectively prevent the blending of
transmix into gasoline from causing any appreciable changes in gasoline
emissions performance.
One commenter said that the 1996 Question and Answer guidance
regarding transmix blended into conventional gasoline requires that the
transmix be blended at a rate no greater than the historical rate that
was used by the pipeline, whereas the NPRM provided that the transmix
be blended at a rate no greater than the historical rate at the
terminal or 0.25 volume percent, whichever is greater. The commenter
said the NPRM did not cover a situation where, historically, transmix
was moved through a pipeline to a terminal that is no longer used for
blending transmix, and the transmix is currently moved through the same
pipeline but blended at an intermediate terminal which historically had
not been used for blending transmix. The commenter recommended that the
language in the Q&A guidance, which covers this situation by allowing
blending at the historical rate used by the pipeline rather than by the
terminal, be adopted in the regulations.
We believe the Q&A guidance is consistent with the 1997 NPRM in
stating that if a pipeline stops blending transmix at a terminal, that
the pipeline may not begin blending transmix at a second terminal at a
rate equal to the first terminal's blending rate. The Q&A guidance
states: ``* * * the transmix must be present in a terminal from which
there is no out-bound pipeline or water transportation by which the
transmix could be transported to a transmix processor, or the
pipeline's historical practice at the terminal [emphasis added] (the
practice beginning at least before January, 1994) has been to blend all
transmix into conventional gasoline without further processing.'' This
language indicates that the criteria regarding historical practice
applies to the terminal in which the transmix was blended by the
pipeline. Where a pipeline blends transmix at more than one terminal,
the historical practice criterion would apply separately to each of the
pipeline's terminals at which transmix is blended. However, as
described below, this proposed rule would change this approach.
2. This Proposal
This proposed rule would eliminate the historical practice
criterion for determining amounts of transmix to be blended into
conventional gasoline and the locations where this may occur, and also
would eliminate the 0.25 volume percent limit for blending transmix in
reformulated gasoline. This proposed rule would instead allow transmix
to be blended into conventional or reformulated gasoline in any
location and in any amount, provided the endpoint of the transmix-
blended gasoline does not exceed 437 degrees Fahrenheit,\3\ and meets
all other applicable downstream standards. As EPA's diesel sulfur
regulations begin phasing in, transmix will be generated at new
locations. EPA believes it is appropriate to allow the flexibility to
blend transmix into gasoline at locations which have not historically
blended transmix, provided the endpoint of the transmix-blended
gasoline does not exceed 437 degrees Fahrenheit, and the gasoline meets
all other applicable downstream standards. In addition, EPA believes it
is appropriate to use gasoline endpoint to regulate transmix blending
because it takes into account the quality of the transmix-blended
gasoline. The historical practice criterion for conventional gasoline
and the 0.25 volume percent limit for RFG were crude approaches that
did not account for the variability of transmix and its effect on the
gasoline into which it was blended.
---------------------------------------------------------------------------

\3\ 437 degrees Fahrenheit is the maximum allowable endpoint for
gasoline specified in ASTM's standard for automotive spark-ignition
engine fuel, D 4814-88. Gasoline endpoint is measured using ASTM
D86-01. ASTM D86-01 measures the percentage of a gasoline sample
that evaporates, as a function of temperature, as the sample is
heated up under controlled conditions. Endpoint is the temperature
at which all the volatile portion of a gasoline sample is
evaporated. ASTM D4814-88 specifies a maximum allowable endpoint of
437 degrees Fahrenheit in order to limit the amount of higher-
boiling point compounds that can be present in the gasoline.
---------------------------------------------------------------------------

EPA believes that blending small percentages of transmix in
gasoline should be allowed at any facility, provided the facility takes
appropriate steps to ensure that the endpoint of the transmix-blended
gasoline does not exceed 437 degrees Fahrenheit. Transmix typically
contains significant percentages of distillate fuels such as diesel
fuel or heating oil, and distillate fuels have higher boiling points
and much lower octane ratings than

[[Page 32024]]

gasoline. EPA's existing guidance regarding transmix blending reflected
a concern that blending excessive amounts of transmix in gasoline could
have an appreciable effect on emissions. However, EPA believes that
where transmix is blended at sufficiently low percentages, such that
the endpoint of the transmix-blended gasoline does not exceed 437
degrees Fahrenheit, the emissions effect of blending transmix in
gasoline will be negligible.
In addition to affecting gasoline endpoint and octane, blending
transmix in gasoline also affects parameters in EPA's complex model,
the model used to ensure that imported or produced gasoline complies
