ACTION: Supplemental notice of proposed rulemaking. AGENCY: This action supplements the proposed amendments to the new source performance standards (NSPS) and emission guidelines (EG) for the Other Solid Waste Incineration (OSWI) units source category published in the Federal Register on August 31, 2020. In that action, the Environmental Protection Agency (EPA) proposed changes to OSWI subcategories and related maximum achievable control technology (MACT) floor redeterminations, applicability-related changes and testing and monitoring flexibilities for certain small OSWI units, among other proposed changes. Based on the EPA’s analysis of comments received after proposal and discussions with the state of Alaska and tribes, we are proposing to add a definition for a rudimentary combustion device and are asking for specific comment on this definition. We are also proposing to postpone developing standards for such devices. DATES: Comments must be received on or before September 9, 2024. Public hearing. If anyone contacts us requesting a public hearing on or before July 30, 2024, we will hold a virtual hearing.

Where can I get a copy of this document and other related information? A memorandum showing the rule edits that would be necessary to incorporate the changes to 40 CFR part 60, subparts EEEE and FFFF proposed in this action is available in the docket (Docket ID No. EPA–HQ–OAR–2003– 0156). Following signature by the EPA Administrator, the EPA also will post a copy of this document to https:// www.epa.gov/stationary-sources-airpollution/other-solid-wasteincinerators-oswi-new-sourceperformance. II. Background A. What is the regulatory history for this action? Section 129 of the CAA requires the EPA to develop and adopt NSPS and EG for solid waste incineration units, in VerDate Sep<11>2014 17:40 Jul 24, 2024 Jkt 262001 accordance with CAA sections 129 and 111. Section 129(a) of the CAA requires the EPA to establish NSPS for new sources, and CAA section 129(b) requires the EPA to establish procedures for states to submit plans for implementing EG for existing sources (see CAA sections 111(b) and (d)). The EPA proposed NSPS and EG for OSWI units on December 9, 2004, and promulgated them on December 16, 2005 (70 FR 74870), at 40 CFR part 60, subparts EEEE and FFFF. Under the 2005 regulations, the term ‘‘OSWI unit’’ means either a very small municipal waste combustion (‘‘VSMWC’’) unit or an institutional waste incinerator (‘‘IWI’’) unit. A VSMWC unit is any municipal waste combustion unit that has the capacity to combust less than 35 tons per day (TPD) of municipal solid waste (MSW) or refuse-derived fuel. An IWI unit is any combustion unit that combusts institutional waste and is a distinct operating unit of the institutional facility (e.g., university, correctional institutions) that generated the waste. As required by section 129 of the CAA, the OSWI NSPS and EG rules set emission standards for nine pollutants: cadmium, carbon monoxide, dioxins/ furans, hydrochloric acid, lead, mercury, oxides of nitrogen, particulate matter, and sulfur dioxide. They also establish opacity standards. CAA section 129(a)(5) requires the EPA to review and, if appropriate, revise the requirements for solid waste incineration units. In 2018, the U.S. District Court for the District of PO 00000 Frm 00016 Fmt 4702 Sfmt 4702 Columbia ordered the EPA to publish a proposed rulemaking by August 31, 2020, and promulgate a final rule by May 31, 2021, because the EPA had not reviewed and revised the 2005 OSWI standards as required by law. Sierra Club v. Wheeler, 330 F. Supp. 3d 407, 413 (D.D.C. 2018).1 The EPA published a proposed rulemaking on August 31, 2020. The EPA proposed testing and monitoring flexibilities to help rudimentary combustion devices demonstrate compliance with the rule, but additional information is needed to address the issues related to these devices. This supplemental notice of proposed rulemaking proposes additional amendments to address issues related to certain rudimentary combustion devices as described in sections II.C. and III. of this preamble. B. What changes did we propose for the OSWI source category in our August 31, 2020, proposal? On August 31, 2020, the EPA published a proposed rule in the Federal Register for the OSWI NSPS and EG rules that addressed the requisite CAA section 129(a)(5) periodic review (85 FR 54178). We proposed that no new developments in practices, processes, or control technologies exist for any OSWI units and that it was not necessary to revise the OSWI standards under CAA section 129(a)(5). In accordance with the EPA’s general authority under CAA section 129(a), we 1 The deadline was extended to June 30, 2025. Sierra Club v. Wheeler, Civ. No. 16–2461, D.

E:\FR\FM\25JYP1.SGM 25JYP1 Federal Register / Vol. 89, No. 143 / Thursday, July 25, 2024 / Proposed Rules proposed: (1) MACT floors for newly proposed small OSWI unit subcategories; (2) changes to applicability provisions for the EG and NSPS including removing the term ‘‘collected from’’ as used in the ‘‘municipal solid waste’’ definition; (3) revised regulatory provisions related to emissions during periods of startup, shutdown, and malfunction (SSM); (4) testing and monitoring flexibilities so that units with rudimentary designs can demonstrate compliance with the rule; (5) provisions for electronic reporting of certain notices and reports; (6) revisions to recordkeeping and reporting provisions consistent with the revised testing and monitoring; (7) changes to title V permitting requirements; and (8) other technical edits, clarifications, and revisions intended to improve the understanding of the rules and improve consistency with other CAA section 129 rules. ddrumheller on DSK120RN23PROD with PROPOSALS1 C. What action is the Agency taking in this action? Based on comments received on the proposed rulemaking and discussions with state and tribal agencies in Alaska regarding rudimentary combustion devices, we are proposing to add a definition for a rudimentary combustion device to address the unique issues associated with them. Comments received on the proposed rulemaking are discussed in section III. of this preamble. The EPA is proposing to define a rudimentary combustion device as a combustion device with a capacity less than or equal to 10 TPD that is designed and constructed without one or more of the following elements: (1) a stack, chimney, or pipe designed for the purpose of managing air flow and discharging flue gases from combustion ; (2) mechanical draft to provide air flow; (3) burners designed to manage the combustion process; (4) an ancillary power supply to operate; or (5) supplemental fuel burners or nozzles. We are also proposing to postpone developing standards for these devices. D. What is the Agency’s authority for taking this action? Section 129 of the CAA requires the EPA to establish NSPS and EG pursuant to sections 111 and 129 of the CAA for new and existing solid waste incineration units, including ‘‘other categories of solid waste incineration units.’’ This action supplements our 2020 proposal 2 to amend the OSWI standards under such authority as discussed in greater detail in section III. of this preamble. In addition, CAA 2 85 FR 54178 (Aug. 31, 2020). VerDate Sep<11>2014 17:40 Jul 24, 2024 Jkt 262001 section 129(a)(5) specifically requires the EPA to review and revise the standards and the requirements for solid waste incineration units, including OSWI units, every 5 years. The EPA has discretion to distinguish among classes, types, and sizes of incinerator units within a category while setting standards. CAA section 129(a)(2) provides that standards ‘‘applicable to solid waste incineration units promulgated under . . . [section 111] and this section shall reflect the maximum degree of reduction in emissions of . . . [listed air pollutants] that the Administrator, taking into consideration the cost of achieving such emission reduction and any non-air quality health and environmental impacts and energy requirements, determines is achievable for new and existing units in each category.’’ E. What outreach and engagement did we conduct? In developing this supplemental proposal, the EPA conducted outreach activities with communities with environmental justice (EJ) concerns, states, and tribes. In addition to public comments received on the 2020 proposal, we obtained feedback from interested parties and evaluated and weighed the information received as we developed this supplemental proposal. In June 2020, the EPA conducted four pre-proposal informational calls for Federally Recognized Tribes, including an overview presentation during the June 25, 2020, National Tribal Air Association (NTAA) call. On August 31, 2020, the EPA sent an email notification to stakeholders announcing that this action had been published with a 45day comment period with an opportunity to request a public hearing. In September 2020, the EPA held several consultation meetings with tribes, including the Northway Village Tribe, Qagan Tayagungin Tribe, Louden Tribe, and the Mescalaro Apache Tribe. The EPA also conducted four informational calls on the OSWI rule in September 2020, including an overview at the Small Business Environmental Assistance Program (SBEAP) Annual Training, the Alaska Air Workgroup call, the Tribal Environmental Leaders Summit call. The EPA also provided an update at the NTAA call. Although a public hearing was not requested, the EPA continued to seek out additional opportunities for communities with EJ concerns and other key interested parties to be informed about potential requirements of this action. Outreach included a presentation to the SBEAP on June 5, 2023; regular meetings with the state of Alaska to discuss units that PO 00000 Frm 00017 Fmt 4702 Sfmt 4702 60345 could potentially be subject to the rule; and a presentation during the National Association of Clean Air Agencies (NACAA) Permitting and New Source Review Committee meeting in October 2020. III. Proposed Revisions We received numerous comments on the August 31, 2020, proposal and held discussions with state and tribal agencies in Alaska regarding rural rudimentary combustion devices and waste management concerns. Following consideration of the information and comments received, we are proposing to add a definition for a rudimentary combustion device to the OSWI rules to address the issues raised by commenters regarding these units. The issues raised are summarized in this section. Several commenters stated that burning MSW in simple burn boxes is a crucial aspect of waste management in rural Alaska. The commenters noted that according to the state of Alaska Solid Waste Program, 147 rural Alaskan landfills practice some type of waste burning. Of these, 118 depend on small burn units to manage their landfills. The commenters added that this inexpensive and effective waste management method helps isolated communities reduce physical waste volume, maintain safety, and extend the useful life of their landfills. The commenters stated that removing the Alaska class II/III municipal solid waste landfill exemption could result in an unfunded mandate and that it would be nearly impossible for most rural Alaskan communities to comply with the proposed standard. Commenters noted the costs for testing, monitoring, recordkeeping and reporting, and controls for these units would be unaffordable for rural Alaskan communities and would result in other methods of disposal that would be less environmentally friendly. Commenters added: • Very little funding is available for solid waste activities. Installing controls, increased operation and maintenance costs, and required monitoring would be financially impossible for rural Alaskan communities and their partner organizations. At a minimum, a new unit capable of meeting the proposed standards would cost several hundred thousand dollars. According to quotes from Anchorage-based stack testers, annual testing would cost $80,000$100,000 per community. • Many communities are likely to abandon their burn units and return to poorer burning practices, such as open burning of waste on the ground or barrel E:\FR\FM\25JYP1.SGM 25JYP1 ddrumheller on DSK120RN23PROD with PROPOSALS1 60346 Federal Register / Vol. 89, No. 143 / Thursday, July 25, 2024 / Proposed Rules burning, which would result in poorer air quality and inhalation exposure to more toxics for the affected areas, and a significant increase in wildfires caused by sparks or flames escaping the area. On the ground burning is also a fire issue for which the majority of villages are ill-prepared due to lack of firefighting equipment. The resident exposures entailed in extinguishing dump fires are substantial, involving a significant portion of the population in fighting the fire with inadequate or no personal protective equipment. If the number of villages with regular ground burning nearly doubled as commenters projected, concomitant doubled risk for dump-origin wildland fires would be expected. • Other communities may return to loose filling waste which would significantly decrease landfill life and increase adverse health and safety impacts of the landfill. This would cause a significant setback in rural waste management for Alaska. Rural Alaskan communities off the road system do not have the option to send their waste to larger regional landfills. Unburned waste attracts wildlife to rural Alaskan landfills. Animals such as bears impose an immediate health and safety risk and the constant prevalence of rabies in the Western Alaskan fox make it exceedingly important that waste disposal practices do not attract these possible vectors of human disease. • Waste burning is not an alternative to landfill disposal in rural Alaska. It is an essential aspect of landfill operations because space for landfill activities is extremely limited and burning waste reduces the physical volume of waste. Burning waste also aids in turning MSW into inert substances that are safe to dispose of locally. Heavy equipment required for traditional landfilling activities is expensive to purchase and difficult to maintain and use in rural Alaskan communities due to economic, environmental, and geological constraints. Burn units allow landfills to use smaller equipment, reducing operating and maintenance costs. Material required to provide adequate cover is not available in vast areas of the state. The spongey tundra that covers most of Western Alaska cannot be used for cover. Likewise, wetland environments, including tundra, make it exceedingly difficult to bury large quantities of non-inert waste without contaminating surface and groundwater sources. • If no to little alternate burning is carried out by these communities the dumpsites are more likely to get out of control, with residents more likely to experience waste contact exposures VerDate Sep<11>2014 17:40 Jul 24, 2024 Jkt 262001 when self-hauling or, as site access and aesthetics incentivize greater storage of waste in town and around homes, when simply conducting daily life in town. Commenters contended that the proposed stack test methods for Alaska burn boxes would be inapplicable or impractical because: • A majority of units do not have a stack, • Those with stacks are not capable of properly being tested as is and would need to be modified resulting in a substantial cost, • The proposed OSWI stack testing requirements would overwhelm existing testing infrastructure and capacity in Alaska. If all the villages that use burn boxes now were to continue operating with the exclusion removed (either by retrofit or new OSWI purchase), 120 villages would require 20 total sets of testing and analysis equipment, and 35 to 40 personnel (i.e., 3–4 person teams could each test only twice per month). This demand would well exceed the current capacity of qualified Alaska companies. Testing equipment must be freighted from far off locations resulting in substantial cost. Field testing logistics would result in substantial cost such as travel costs, and testing could only be performed with favorable wind conditions, resulting in delaying and extending testing, • The proposed test methods and sample numbers were not designed for this type of unit. The method assumes that the unit is operating for a minimum of 1 hour. However, there is no ignition and temperature control. Once the unit is lit, the batch burns. Regardless of the heterogeneity of the MSW, the average emissions and temperature vary substantially from load to load depending on how it is lit and how the load is placed. Because the test methods are inapplicable, a separate testing procedure would have to be developed by the testing company and approved by the EPA—for each burnbox type and field condition. • Operating a retrofitted or newly purchased incinerator capable of passing a stack test would add additional costs each year thereafter, regardless of whether it is a testing year. A commenter added that the definition of OSWI is inapplicable to burnboxes, which are dissimilar in multiple ways, as follows: • Burnboxes are absent a waste feed system, flue gas system, heat recovery and bottom ash system. • Burnboxes contain only a single chamber. There is no flue gas ‘‘system.’’ Burnboxes operate with natural venting. • Burnboxes lack a bottom ash system or equipment that transfers the ash. A PO 00000 Frm 00018 Fmt 4702 Sfmt 4702 shovel is used for ash or it is tipped out and deposited there. There is no final disposal. Following consideration of the comments received and discussions with state and tribal agencies, we are proposing to add a definition for rudimentary combustion device. The state of Alaska and communications with tribal representatives have provided us with additional information on the types of units used in rural communities spread across Alaska, many of which are located within Native American villages, and have small populations that have extremely limited financial resources. This information is available in the docket. We agree with commenters that many of these communities have limited road access to haul waste to a larger community for burning or landfilling. As a result, local waste disposal is the only option available. The rudimentary combustion devices used in these villages are often primitive in nature; often not commercially constructed or engineered; and have capacities less than 10 TPD. Because villages are likely to abandon their burn units and return to poorer burning practices, such as open burning of waste on the ground, if required to comply with the August 31, 2020, OSWI proposed rule, the EPA has determined that the affected areas would experience poorer air quality and a significant increase in risk of wildfires caused by sparks or flames escaping burning areas. We also agree with the commenters that some communities might return to loose-filling waste, which would significantly decrease landfill life and increase adverse health and safety impacts of the landfill. We agree these results would cause a significant setback in rural waste management for Alaska. We consider this a negative outcome of regulating these rudimentary combustion devices under the OSWI rules and are taking into consideration their unique situation for the final rulemaking. We reviewed incinerator information submitted in comment letters and in communications with tribal leaders and the state of Alaska to determine the characteristics of these units. As a result, we are proposing to define ‘‘rudimentary combustion device’’ as a combustion device with capacity less than or equal to 10 TPD that is designed and constructed without one or more of the following elements: (1) a stack, chimney, or pipe designed for the purpose of managing air flow and discharging flue gases from E:\FR\FM\25JYP1.SGM 25JYP1 Federal Register / Vol. 89, No. 143 / Thursday, July 25, 2024 / Proposed Rules ddrumheller on DSK120RN23PROD with PROPOSALS1 combustion; 3 (2) mechanical draft to provide airflow; (3) burners designed to manage the combustion process; (4) an ancillary power supply to operate; or (5) supplemental fuel burners or nozzles. These elements may also apply to small incineration units in the contiguous United States, particularly in rural areas. Because rudimentary combustion devices lack one or more of these elements, the emissions information, limits, and controls developed for the proposed OSWI rule would not be appropriate for them. Consequently, we are also proposing to postpone regulating rudimentary combustion devices. The EPA will undertake a separate rulemaking specific to these units. IV. Request for Comments We are not opening comment on aspects of the 2020 proposal (85 FR 54178) that have not changed and are not addressed in this supplemental proposal. Those comments will be addressed in the EPA’s Response to Comments document and in the final rule preamble for the OSWI source category. We do however solicit comments on this supplemental proposed action. In addition to general comments on this supplemental proposed action, the EPA is interested in additional data to refine the definition of ‘‘rudimentary combustion device,’’ including additional parameters that should be considered, capacity (tpd) and location of specific units, the number of devices per rural community, the five design elements, and any emissions test information available for them. We are also requesting information on the number of individuals in rural communities that use a rudimentary combustion device. Additionally, we request comments on the rudimentary combustion device definition, including the proposed capacity threshold of less than or equal to 10 tpd for a rudimentary combustion device, and, more specifically, whether a smaller capacity threshold of less than 10 tpd would adequately capture these rudimentary combustion devices. We would also like to hear from the public, including states, tribes, and local governments, if this proposed definition, including the amount of waste being burned in rudimentary combustion devices, presents regulatory issues or unintended consequences. In the 2020 OSWI proposal, the EPA proposed to remove the definition of the term ‘‘collected from’’ as used in, and 3 Under this element, the source does not have an exhaust stack. VerDate Sep<11>2014 17:40 Jul 24, 2024 Jkt 262001 60347 limiting the definition of, ‘‘municipal solid waste’’ in order to place focus on the source and type or nature of the waste, rather than the manner in which it is ‘‘collected’’ (85 FR 54186–87). The Agency did not receive any adverse comments. In light of the proposed change in this supplemental proposal, to add a definition of rudimentary combustion device, and this proposed change in the 2020 OSWI proposal to modify the definition of ‘‘municipal solid waste,’’ we are also soliciting comment on removing ‘‘collected from’’ from the ‘‘municipal solid waste’’ definition. A. Executive Order 12866: Regulatory Planning and Review and Executive Order 14094: Modernizing Regulatory Review This action is not a significant regulatory action as defined in Executive Order 12866, as amended by Executive Order 14094, and was therefore not subject to a requirement for Executive Order 12866 review. V. Summary of Cost, Environmental, and Economic Impacts C. Regulatory Flexibility Act (RFA) I certify that this action will not have a significant economic impact on a substantial number of small entities under the RFA. The small entities that may be subject to the requirements of this action are small businesses, small government jurisdictions, and small nonprofits that operate rudimentary combustion devices currently subject to the OSWI EG and NSPS. This supplemental proposal defines rudimentary combustion device and proposes to postpone developing standards for devices owned by small entities that meet the definition of rudimentary combustion device. We have therefore concluded that this action will have no regulatory burden for all directly regulated small entities. A. What are the affected facilities? We do not believe that we have complete information on the number of rudimentary combustion devices. We estimate that the OSWI database developed for the August 31, 2020, proposal includes at least 130 facilities with 143 units that may be rudimentary combustion devices. Through contacts with Alaskan state officials and tribal leaders, we have learned that there may be an additional 200 to 400 incinerators that could be classified as rudimentary combustion devices in Alaska. Due to their limited capacities, we believe that rudimentary combustion devices may be regulated by local governments through zoning or other ordinances. B. What are the air quality impacts? There are no air quality impacts associated with this supplemental proposal. The proposed addition of the rudimentary combustion device definition does not have an effect on the stringency of the standards in 40 CFR part 60, subparts EEEE or FFFF. C. What are the cost and economic impacts? There are no cost or economic impacts associated with this supplemental proposal. The proposed addition of the rudimentary combustion device definition does not have an effect on the stringency of the standards in 40 CFR part 60, subparts EEEE or FFFF. VI. Statutory and Executive Order Reviews Additional information about these statutes and Executive Orders can be found at https://www.epa.gov/lawsregulations/laws-and-executive-orders. PO 00000 Frm 00019 Fmt 4702 Sfmt 4702 B. Paperwork Reduction Act (PRA) This supplemental proposal does not impose an information collection burden under the PRA. There are no information collection request activities associated with this action. D. Unfunded Mandates Reform Act (UMRA) This supplemental proposal does not contain an unfunded mandate of $100 million or more as described in the UMRA, 2 U.S.C. 1531–1538, and does not significantly or uniquely affect small governments. This action imposes no enforceable duty on any State, local or Tribal governments or the private sector. E. Executive Order 13132: Federalism This supplemental proposal does not have federalism implications. It will 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. F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments This supplemental proposal has Tribal implications. However, it will neither impose substantial direct compliance costs on federally recognized Tribal governments, nor preempt Tribal law. This action E:\FR\FM\25JYP1.SGM 25JYP1 60348 Federal Register / Vol. 89, No. 143 / Thursday, July 25, 2024 / Proposed Rules proposes to provide regulatory relief to units that meet the definition of rudimentary combustion device. The EPA consulted with Tribal officials under the EPA Policy on Consultation and Coordination with Indian Tribes early in the process of developing this supplemental proposal to have meaningful and timely input into its development. A summary of that consultation is provided in section II.E. of this preamble. ddrumheller on DSK120RN23PROD with PROPOSALS1 G. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks The EPA interprets Executive Order 13045 as applying only to those regulatory actions that concern environmental health or safety risks that the EPA has reason to believe may disproportionately affect children, per the definition of ‘‘covered regulatory action’’ in section 2–202 of the Executive Order. Therefore, this supplemental proposal is not subject to Executive Order 13045 because it does not concern an environmental health risk or safety risk. Since this action does not concern human health, the EPA’s Policy on Children’s Health also does not apply. VerDate Sep<11>2014 17:40 Jul 24, 2024 Jkt 262001 H. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use This supplemental proposal is not a ‘‘significant energy action’’ because it is not likely to have a significant adverse effect on the supply, distribution or use of energy. Further, we have concluded that this supplemental proposal is not likely to have adverse energy effects because this supplemental proposal does not involve energy supply, distribution, or use of energy. I. National Technology Transfer and Advancement Act (NTTAA) and 1 CFR Part 51 This supplemental proposal does not involve technical standards. J. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations and Executive Order 14096: Revitalizing Our Nation’s Commitment to Environmental Justice for All The EPA believes that it is not practicable to assess whether the human health or environmental conditions that PO 00000 Frm 00020 Fmt 4702 Sfmt 9990 exist prior to this supplemental proposal result in disproportionate and adverse effects on communities with environmental justice concerns. The EPA is not aware of the number of incineration units that will meet the definition of rudimentary combustion device. Therefore, the EPA is unable to fully evaluate a potential baseline for environmental justice concerns. The EPA identified and addressed environmental justice concerns by conducting outreach activities with communities with environmental justice concerns, states, and tribes.

Standards of Performance for New Stationary Sources and Emission 
Guidelines for Existing Sources: Other Solid Waste Incineration Units 
Revisions to Definitions

AGENCY: Environmental Protection Agency (EPA).

ACTION: Supplemental notice of proposed rulemaking.

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

SUMMARY: This action supplements the proposed amendments to the new 
source performance standards (NSPS) and emission guidelines (EG) for 
the Other Solid Waste Incineration (OSWI) units source category 
published in the Federal Register on August 31, 2020. In that action, 
the Environmental Protection Agency (EPA) proposed changes to OSWI 
subcategories and related maximum achievable control technology (MACT) 
floor redeterminations, applicability-related changes and testing and 
monitoring flexibilities for certain small OSWI units, among other 
proposed changes. Based on the EPA's analysis of comments received 
after proposal and discussions with the state of Alaska and tribes, we 
are proposing to add a definition for a rudimentary combustion device 
and are asking for specific comment on this definition. We are also 
proposing to postpone developing standards for such devices.

A. Does this action apply to me?

    Categories and entities potentially affected by this supplemental 
proposal are those that operate rudimentary combustion devices as 
described in section II.C. of this preamble and currently subject to 
the OSWI EG and NSPS. OSWI units are not commercial and industrial 
solid waste incineration units (CISWI), hazardous waste combustion 
units, hospital/medical/infectious waste incinerators, sewage sludge 
incinerators, or other incinerators regulated under other provisions of 
section 129 of the Clean Air Act (CAA). The NSPS and EG for OSWI, 
hereinafter referred to as ``the OSWI standards,'' affect the 
categories of sources identified in table 1 of this preamble:

II. Background

A. What is the regulatory history for this action?

    Section 129 of the CAA requires the EPA to develop and adopt NSPS 
and EG for solid waste incineration units, in accordance with CAA 
sections 129 and 111. Section 129(a) of the CAA requires the EPA to 
establish NSPS for new sources, and CAA section 129(b) requires the EPA 
to establish procedures for states to submit plans for implementing EG 
for existing sources (see CAA sections 111(b) and (d)). The EPA 
proposed NSPS and EG for OSWI units on December 9, 2004, and 
promulgated them on December 16, 2005 (70 FR 74870), at 40 CFR part 60, 
subparts EEEE and FFFF.
    Under the 2005 regulations, the term ``OSWI unit'' means either a 
very small municipal waste combustion (``VSMWC'') unit or an 
institutional waste incinerator (``IWI'') unit. A VSMWC unit is any 
municipal waste combustion unit that has the capacity to combust less 
than 35 tons per day (TPD) of municipal solid waste (MSW) or refuse-
derived fuel. An IWI unit is any combustion unit that combusts 
institutional waste and is a distinct operating unit of the 
institutional facility (e.g., university, correctional institutions) 
that generated the waste. As required by section 129 of the CAA, the 
OSWI NSPS and EG rules set emission standards for nine pollutants: 
cadmium, carbon monoxide, dioxins/furans, hydrochloric acid, lead, 
mercury, oxides of nitrogen, particulate matter, and sulfur dioxide. 
They also establish opacity standards.
    CAA section 129(a)(5) requires the EPA to review and, if 
appropriate, revise the requirements for solid waste incineration 
units. In 2018, the U.S. District Court for the District of Columbia 
ordered the EPA to publish a proposed rulemaking by August 31, 2020, 
and promulgate a final rule by May 31, 2021, because the EPA had not 
reviewed and revised the 2005 OSWI standards as required by law. Sierra 
Club v. Wheeler, 330 F. Supp. 3d 407, 413 (D.D.C. 2018).\1\ The EPA 
published a proposed rulemaking on August 31, 2020. The EPA proposed 
testing and monitoring flexibilities to help rudimentary combustion 
devices demonstrate compliance with the rule, but additional 
information is needed to address the issues related to these devices. 
This supplemental notice of proposed rulemaking proposes additional 
amendments to address issues related to certain rudimentary combustion 
devices as described in sections II.C. and III. of this preamble.
---------------------------------------------------------------------------

    \1\ The deadline was extended to June 30, 2025. Sierra Club v. 
Wheeler, Civ. No. 16-2461, D. DC, Minute Order filed 11/7/2023.
---------------------------------------------------------------------------

B. What changes did we propose for the OSWI source category in our 
August 31, 2020, proposal?

    On August 31, 2020, the EPA published a proposed rule in the 
Federal Register for the OSWI NSPS and EG rules that addressed the 
requisite CAA section 129(a)(5) periodic review (85 FR 54178). We 
proposed that no new developments in practices, processes, or control 
technologies exist for any OSWI units and that it was not necessary to 
revise the OSWI standards under CAA section 129(a)(5). In accordance 
with the EPA's general authority under CAA section 129(a), we

[[Page 60345]]

proposed: (1) MACT floors for newly proposed small OSWI unit 
subcategories; (2) changes to applicability provisions for the EG and 
NSPS including removing the term ``collected from'' as used in the 
``municipal solid waste'' definition; (3) revised regulatory provisions 
related to emissions during periods of startup, shutdown, and 
malfunction (SSM); (4) testing and monitoring flexibilities so that 
units with rudimentary designs can demonstrate compliance with the 
rule; (5) provisions for electronic reporting of certain notices and 
reports; (6) revisions to recordkeeping and reporting provisions 
consistent with the revised testing and monitoring; (7) changes to 
title V permitting requirements; and (8) other technical edits, 
clarifications, and revisions intended to improve the understanding of 
the rules and improve consistency with other CAA section 129 rules.

C. What action is the Agency taking in this action?

    Based on comments received on the proposed rulemaking and 
discussions with state and tribal agencies in Alaska regarding 
rudimentary combustion devices, we are proposing to add a definition 
for a rudimentary combustion device to address the unique issues 
associated with them. Comments received on the proposed rulemaking are 
discussed in section III. of this preamble. The EPA is proposing to 
define a rudimentary combustion device as a combustion device with a 
capacity less than or equal to 10 TPD that is designed and constructed 
without one or more of the following elements: (1) a stack, chimney, or 
pipe designed for the purpose of managing air flow and discharging flue 
gases from combustion ; (2) mechanical draft to provide air flow; (3) 
burners designed to manage the combustion process; (4) an ancillary 
power supply to operate; or (5) supplemental fuel burners or nozzles. 
We are also proposing to postpone developing standards for these 
devices.

D. What is the Agency's authority for taking this action?

    Section 129 of the CAA requires the EPA to establish NSPS and EG 
pursuant to sections 111 and 129 of the CAA for new and existing solid 
waste incineration units, including ``other categories of solid waste 
incineration units.'' This action supplements our 2020 proposal \2\ to 
amend the OSWI standards under such authority as discussed in greater 
detail in section III. of this preamble. In addition, CAA section 
129(a)(5) specifically requires the EPA to review and revise the 
standards and the requirements for solid waste incineration units, 
including OSWI units, every 5 years.
---------------------------------------------------------------------------

    \2\ 85 FR 54178 (Aug. 31, 2020).
---------------------------------------------------------------------------

    The EPA has discretion to distinguish among classes, types, and 
sizes of incinerator units within a category while setting standards. 
CAA section 129(a)(2) provides that standards ``applicable to solid 
waste incineration units promulgated under . . . [section 111] and this 
section shall reflect the maximum degree of reduction in emissions of . 
. . [listed air pollutants] that the Administrator, taking into 
consideration the cost of achieving such emission reduction and any 
non-air quality health and environmental impacts and energy 
requirements, determines is achievable for new and existing units in 
each category.''

E. What outreach and engagement did we conduct?

    In developing this supplemental proposal, the EPA conducted 
outreach activities with communities with environmental justice (EJ) 
concerns, states, and tribes. In addition to public comments received 
on the 2020 proposal, we obtained feedback from interested parties and 
evaluated and weighed the information received as we developed this 
supplemental proposal. In June 2020, the EPA conducted four pre-
proposal informational calls for Federally Recognized Tribes, including 
an overview presentation during the June 25, 2020, National Tribal Air 
Association (NTAA) call. On August 31, 2020, the EPA sent an email 
notification to stakeholders announcing that this action had been 
published with a 45-day comment period with an opportunity to request a 
public hearing. In September 2020, the EPA held several consultation 
meetings with tribes, including the Northway Village Tribe, Qagan 
Tayagungin Tribe, Louden Tribe, and the Mescalaro Apache Tribe. The EPA 
also conducted four informational calls on the OSWI rule in September 
2020, including an overview at the Small Business Environmental 
Assistance Program (SBEAP) Annual Training, the Alaska Air Workgroup 
call, the Tribal Environmental Leaders Summit call. The EPA also 
provided an update at the NTAA call. Although a public hearing was not 
requested, the EPA continued to seek out additional opportunities for 
communities with EJ concerns and other key interested parties to be 
informed about potential requirements of this action. Outreach included 
a presentation to the SBEAP on June 5, 2023; regular meetings with the 
state of Alaska to discuss units that could potentially be subject to 
the rule; and a presentation during the National Association of Clean 
Air Agencies (NACAA) Permitting and New Source Review Committee meeting 
in October 2020.

III. Proposed Revisions

    We received numerous comments on the August 31, 2020, proposal and 
held discussions with state and tribal agencies in Alaska regarding 
rural rudimentary combustion devices and waste management concerns. 
Following consideration of the information and comments received, we 
are proposing to add a definition for a rudimentary combustion device 
to the OSWI rules to address the issues raised by commenters regarding 
these units. The issues raised are summarized in this section.
    Several commenters stated that burning MSW in simple burn boxes is 
a crucial aspect of waste management in rural Alaska. The commenters 
noted that according to the state of Alaska Solid Waste Program, 147 
rural Alaskan landfills practice some type of waste burning. Of these, 
118 depend on small burn units to manage their landfills. The 
commenters added that this inexpensive and effective waste management 
method helps isolated communities reduce physical waste volume, 
maintain safety, and extend the useful life of their landfills. The 
commenters stated that removing the Alaska class II/III municipal solid 
waste landfill exemption could result in an unfunded mandate and that 
it would be nearly impossible for most rural Alaskan communities to 
comply with the proposed standard. Commenters noted the costs for 
testing, monitoring, recordkeeping and reporting, and controls for 
these units would be unaffordable for rural Alaskan communities and 
would result in other methods of disposal that would be less 
environmentally friendly. Commenters added:
     Very little funding is available for solid waste 
activities. Installing controls, increased operation and maintenance 
costs, and required monitoring would be financially impossible for 
rural Alaskan communities and their partner organizations. At a 
minimum, a new unit capable of meeting the proposed standards would 
cost several hundred thousand dollars. According to quotes from 
Anchorage-based stack testers, annual testing would cost $80,000-
$100,000 per community.
     Many communities are likely to abandon their burn units 
and return to poorer burning practices, such as open burning of waste 
on the ground or barrel

[[Page 60346]]

burning, which would result in poorer air quality and inhalation 
exposure to more toxics for the affected areas, and a significant 
increase in wildfires caused by sparks or flames escaping the area. On 
the ground burning is also a fire issue for which the majority of 
villages are ill-prepared due to lack of firefighting equipment. The 
resident exposures entailed in extinguishing dump fires are 
substantial, involving a significant portion of the population in 
fighting the fire with inadequate or no personal protective equipment. 
If the number of villages with regular ground burning nearly doubled as 
commenters projected, concomitant doubled risk for dump-origin wildland 
fires would be expected.
     Other communities may return to loose filling waste which 
would significantly decrease landfill life and increase adverse health 
and safety impacts of the landfill. This would cause a significant 
setback in rural waste management for Alaska. Rural Alaskan communities 
off the road system do not have the option to send their waste to 
larger regional landfills. Unburned waste attracts wildlife to rural 
Alaskan landfills. Animals such as bears impose an immediate health and 
safety risk and the constant prevalence of rabies in the Western 
Alaskan fox make it exceedingly important that waste disposal practices 
do not attract these possible vectors of human disease.
     Waste burning is not an alternative to landfill disposal 
in rural Alaska. It is an essential aspect of landfill operations 
because space for landfill activities is extremely limited and burning 
waste reduces the physical volume of waste. Burning waste also aids in 
turning MSW into inert substances that are safe to dispose of locally. 
Heavy equipment required for traditional landfilling activities is 
expensive to purchase and difficult to maintain and use in rural 
Alaskan communities due to economic, environmental, and geological 
constraints. Burn units allow landfills to use smaller equipment, 
reducing operating and maintenance costs. Material required to provide 
adequate cover is not available in vast areas of the state. The spongey 
tundra that covers most of Western Alaska cannot be used for cover. 
Likewise, wetland environments, including tundra, make it exceedingly 
difficult to bury large quantities of non-inert waste without 
contaminating surface and groundwater sources.
     If no to little alternate burning is carried out by these 
communities the dumpsites are more likely to get out of control, with 
residents more likely to experience waste contact exposures when self-
hauling or, as site access and aesthetics incentivize greater storage 
of waste in town and around homes, when simply conducting daily life in 
town.
    Commenters contended that the proposed stack test methods for 
Alaska burn boxes would be inapplicable or impractical because:
     A majority of units do not have a stack,
     Those with stacks are not capable of properly being tested 
as is and would need to be modified resulting in a substantial cost,
     The proposed OSWI stack testing requirements would 
overwhelm existing testing infrastructure and capacity in Alaska. If 
all the villages that use burn boxes now were to continue operating 
with the exclusion removed (either by retrofit or new OSWI purchase), 
120 villages would require 20 total sets of testing and analysis 
equipment, and 35 to 40 personnel (i.e., 3-4 person teams could each 
test only twice per month). This demand would well exceed the current 
capacity of qualified Alaska companies. Testing equipment must be 
freighted from far off locations resulting in substantial cost. Field 
testing logistics would result in substantial cost such as travel 
costs, and testing could only be performed with favorable wind 
conditions, resulting in delaying and extending testing,
     The proposed test methods and sample numbers were not 
designed for this type of unit. The method assumes that the unit is 
operating for a minimum of 1 hour. However, there is no ignition and 
temperature control. Once the unit is lit, the batch burns. Regardless 
of the heterogeneity of the MSW, the average emissions and temperature 
vary substantially from load to load depending on how it is lit and how 
the load is placed. Because the test methods are inapplicable, a 
separate testing procedure would have to be developed by the testing 
company and approved by the EPA--for each burnbox type and field 
condition.
     Operating a retrofitted or newly purchased incinerator 
capable of passing a stack test would add additional costs each year 
thereafter, regardless of whether it is a testing year.
    A commenter added that the definition of OSWI is inapplicable to 
burnboxes, which are dissimilar in multiple ways, as follows:
     Burnboxes are absent a waste feed system, flue gas system, 
heat recovery and bottom ash system.
     Burnboxes contain only a single chamber. There is no flue 
gas ``system.'' Burnboxes operate with natural venting.
     Burnboxes lack a bottom ash system or equipment that 
transfers the ash. A shovel is used for ash or it is tipped out and 
deposited there. There is no final disposal.
    Following consideration of the comments received and discussions 
with state and tribal agencies, we are proposing to add a definition 
for rudimentary combustion device. The state of Alaska and 
communications with tribal representatives have provided us with 
additional information on the types of units used in rural communities 
spread across Alaska, many of which are located within Native American 
villages, and have small populations that have extremely limited 
financial resources. This information is available in the docket. We 
agree with commenters that many of these communities have limited road 
access to haul waste to a larger community for burning or landfilling. 
As a result, local waste disposal is the only option available. The 
rudimentary combustion devices used in these villages are often 
primitive in nature; often not commercially constructed or engineered; 
and have capacities less than 10 TPD. Because villages are likely to 
abandon their burn units and return to poorer burning practices, such 
as open burning of waste on the ground, if required to comply with the 
August 31, 2020, OSWI proposed rule, the EPA has determined that the 
affected areas would experience poorer air quality and a significant 
increase in risk of wildfires caused by sparks or flames escaping 
burning areas. We also agree with the commenters that some communities 
might return to loose-filling waste, which would significantly decrease 
landfill life and increase adverse health and safety impacts of the 
landfill. We agree these results would cause a significant setback in 
rural waste management for Alaska. We consider this a negative outcome 
of regulating these rudimentary combustion devices under the OSWI rules 
and are taking into consideration their unique situation for the final 
rulemaking.
    We reviewed incinerator information submitted in comment letters 
and in communications with tribal leaders and the state of Alaska to 
determine the characteristics of these units. As a result, we are 
proposing to define ``rudimentary combustion device'' as a combustion 
device with capacity less than or equal to 10 TPD that is designed and 
constructed without one or more of the following elements: (1) a stack, 
chimney, or pipe designed for the purpose of managing air flow and 
discharging flue gases from

[[Page 60347]]

combustion; \3\ (2) mechanical draft to provide airflow; (3) burners 
designed to manage the combustion process; (4) an ancillary power 
supply to operate; or (5) supplemental fuel burners or nozzles. These 
elements may also apply to small incineration units in the contiguous 
United States, particularly in rural areas. Because rudimentary 
combustion devices lack one or more of these elements, the emissions 
information, limits, and controls developed for the proposed OSWI rule 
would not be appropriate for them. Consequently, we are also proposing 
to postpone regulating rudimentary combustion devices. The EPA will 
undertake a separate rulemaking specific to these units.
---------------------------------------------------------------------------

    \3\ Under this element, the source does not have an exhaust 
stack.
---------------------------------------------------------------------------

IV. Request for Comments

    We are not opening comment on aspects of the 2020 proposal (85 FR 
54178) that have not changed and are not addressed in this supplemental 
proposal. Those comments will be addressed in the EPA's Response to 
Comments document and in the final rule preamble for the OSWI source 
category.
    We do however solicit comments on this supplemental proposed 
action. In addition to general comments on this supplemental proposed 
action, the EPA is interested in additional data to refine the 
definition of ``rudimentary combustion device,'' including additional 
parameters that should be considered, capacity (tpd) and location of 
specific units, the number of devices per rural community, the five 
design elements, and any emissions test information available for them. 
We are also requesting information on the number of individuals in 
rural communities that use a rudimentary combustion device. 
Additionally, we request comments on the rudimentary combustion device 
definition, including the proposed capacity threshold of less than or 
equal to 10 tpd for a rudimentary combustion device, and, more 
specifically, whether a smaller capacity threshold of less than 10 tpd 
would adequately capture these rudimentary combustion devices. We would 
also like to hear from the public, including states, tribes, and local 
governments, if this proposed definition, including the amount of waste 
being burned in rudimentary combustion devices, presents regulatory 
issues or unintended consequences.
    In the 2020 OSWI proposal, the EPA proposed to remove the 
definition of the term ``collected from'' as used in, and limiting the 
definition of, ``municipal solid waste'' in order to place focus on the 
source and type or nature of the waste, rather than the manner in which 
it is ``collected'' (85 FR 54186-87). The Agency did not receive any 
adverse comments. In light of the proposed change in this supplemental 
proposal, to add a definition of rudimentary combustion device, and 
this proposed change in the 2020 OSWI proposal to modify the definition 
of ``municipal solid waste,'' we are also soliciting comment on 
removing ``collected from'' from the ``municipal solid waste'' 
definition.

V. Summary of Cost, Environmental, and Economic Impacts

A. What are the affected facilities?

    We do not believe that we have complete information on the number 
of rudimentary combustion devices. We estimate that the OSWI database 
developed for the August 31, 2020, proposal includes at least 130 
facilities with 143 units that may be rudimentary combustion devices. 
Through contacts with Alaskan state officials and tribal leaders, we 
have learned that there may be an additional 200 to 400 incinerators 
that could be classified as rudimentary combustion devices in Alaska. 
Due to their limited capacities, we believe that rudimentary combustion 
devices may be regulated by local governments through zoning or other 
ordinances.

B. What are the air quality impacts?

    There are no air quality impacts associated with this supplemental 
proposal. The proposed addition of the rudimentary combustion device 
definition does not have an effect on the stringency of the standards 
in 40 CFR part 60, subparts EEEE or FFFF.

C. What are the cost and economic impacts?

    There are no cost or economic impacts associated with this 
supplemental proposal. The proposed addition of the rudimentary 
combustion device definition does not have an effect on the stringency 
of the standards in 40 CFR part 60, subparts EEEE or FFFF.

VI. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders 
can be found at https://www.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 14094: Modernizing Regulatory Review

    This action is not a significant regulatory action as defined in 
Executive Order 12866, as amended by Executive Order 14094, and was 
therefore not subject to a requirement for Executive Order 12866 
review.

B. Paperwork Reduction Act (PRA)

    This supplemental proposal does not impose an information 
collection burden under the PRA. There are no information collection 
request activities associated with this action.

C. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. The 
small entities that may be subject to the requirements of this action 
are small businesses, small government jurisdictions, and small 
nonprofits that operate rudimentary combustion devices currently 
subject to the OSWI EG and NSPS. This supplemental proposal defines 
rudimentary combustion device and proposes to postpone developing 
standards for devices owned by small entities that meet the definition 
of rudimentary combustion device. We have therefore concluded that this 
action will have no regulatory burden for all directly regulated small 
entities.

D. Unfunded Mandates Reform Act (UMRA)

    This supplemental proposal does not contain an unfunded mandate of 
$100 million or more as described in the UMRA, 2 U.S.C. 1531-1538, and 
does not significantly or uniquely affect small governments. This 
action imposes no enforceable duty on any State, local or Tribal 
governments or the private sector.

E. Executive Order 13132: Federalism

    This supplemental proposal does not have federalism implications. 
It will 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.

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

    This supplemental proposal has Tribal implications. However, it 
will neither impose substantial direct compliance costs on federally 
recognized Tribal governments, nor preempt Tribal law. This action

[[Page 60348]]

proposes to provide regulatory relief to units that meet the definition 
of rudimentary combustion device.
    The EPA consulted with Tribal officials under the EPA Policy on 
Consultation and Coordination with Indian Tribes early in the process 
of developing this supplemental proposal to have meaningful and timely 
input into its development. A summary of that consultation is provided 
in section II.E. of this preamble.

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

    The EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that concern environmental health or safety risks 
that the EPA has reason to believe may disproportionately affect 
children, per the definition of ``covered regulatory action'' in 
section 2-202 of the Executive Order.
    Therefore, this supplemental proposal is not subject to Executive 
Order 13045 because it does not concern an environmental health risk or 
safety risk. Since this action does not concern human health, the EPA's 
Policy on Children's Health also does not apply.

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

    This supplemental proposal is not a ``significant energy action'' 
because it is not likely to have a significant adverse effect on the 
supply, distribution or use of energy. Further, we have concluded that 
this supplemental proposal is not likely to have adverse energy effects 
because this supplemental proposal does not involve energy supply, 
distribution, or use of energy.

I. National Technology Transfer and Advancement Act (NTTAA) and 1 CFR 
Part 51

    This supplemental proposal does not involve technical standards.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations and 
Executive Order 14096: Revitalizing Our Nation's Commitment to 
Environmental Justice for All

    The EPA believes that it is not practicable to assess whether the 
human health or environmental conditions that exist prior to this 
supplemental proposal result in disproportionate and adverse effects on 
communities with environmental justice concerns. The EPA is not aware 
of the number of incineration units that will meet the definition of 
rudimentary combustion device. Therefore, the EPA is unable to fully 
evaluate a potential baseline for environmental justice concerns.
    The EPA identified and addressed environmental justice concerns by 
conducting outreach activities with communities with environmental 
justice concerns, states, and tribes.
    The information supporting this Executive Order review is contained 
in section II.E. of this preamble.
