These amendments implement the plain language reading of the "major source" and "area source" definitions of section 112 of the Clean Air Act (CAA) and provide that a major source can be reclassified to area source status at any time upon reducing its potential to emit (PTE) hazardous air pollutants (HAP) to below the major source thresholds (MST) of 10 tons per year (tpy) of any single HAP and 25 tpy of any combination of HAP. This rule also finalizes amendments to clarify the compliance dates, notification, and recordkeeping requirements that apply to sources choosing to reclassify to area source status and to sources that revert back to major source status, including a requirement for electronic notification. 86 FR 13819 A Court Vacatur of Exemption From Emission Standards During Periods of Startup, Shutdown, and Malfunction 3/11/2021 The U.S. Environmental Protection Agency (EPA) is amending the Code of Federal Regulations (CFR) to reflect a court order regarding the General Provisions for National Emissions Standards for Hazardous Air Pollutants (NESHAP) issued on December 19, 2008, by the United States Court of Appeals for the District of Columbia Circuit (the court). The court vacated two provisions in the General Provisions that exempted sources from hazardous air pollutant (HAP) non-opacity and opacity emission standards during periods of startup, shutdown, and malfunction (SSM). The court held that under the Clean Air Act (CAA), emissions standards or limitations must be continuous in nature and that the SSM exemptions in these two provisions violate this requirement. This ministerial action revises these two NESHAP General Provisions in the CFR to conform to the court's order. 87 FR 393 C Clean Air Act Section 112 List of Hazardous Air Pollutant: Amendments to the List of Hazardous Air Pollutants (HAP) 2/4/2022 The U.S. Environmental Protection Agency (EPA) is amending the list of hazardous air pollutants (HAP) under Clean Air Act (CAA) to add 1-bromopropane (1-BP) in response to public petitions previously granted by the EPA. This action amends the list of hazardous air pollutants initially listed under the CAA. 87 FR 8197 AAAA National Emission Standards for Hazardous Air Pollutants: Municipal Solid Waste Landfills Residual Risk and Technology Review; Correction 2/14/2022 In this action, the U.S. Environmental Protection Agency (EPA) is finalizing technical revisions and clarifications for the national emission standards for hazardous air pollutants (NESHAP) for MSW Landfills established in the March 26, 2020, final rule. This final rule also amends the MSW Landfills NSPS at 40 CFR part 60, subpart XXX, to clarify and align the timing of compliance for certain requirements involving installation of a gas collection and control system (GCCS) under related MSW landfill rules. Additionally, the EPA is revising the definition of Administrator in the MSW Landfills Federal Plan that was promulgated on May 21, 2021 to clarify who has the authority to implement and enforce the applicable requirements. The EPA is also making some minor typographical corrections. 87 FR 13183 YYYY National Emission Standards for Hazardous Air Pollutants: Stationary Combustion Turbines; Amendments 3/9/2022 The U.S. Environmental Protection Agency (EPA) is finalizing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Stationary Combustion Turbines. This final action removes the stay of the effectiveness of the standards for new lean premix and diffusion flame gas-fired turbines that was promulgated in 2004. 87 FR 48603 ZZZZ National Emission Standards for Hazardous Air Pollutants for Reciprocating Internal Combustion Engines; New Source Performance Standards for Stationary Internal Combustion Engines; Court Vacatur 8/10/2022 The Environmental Protection Agency (EPA) is amending the Code of Federal Regulations (CFR) to reflect a 2015 court decision regarding the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Stationary Reciprocating Internal Combustion Engines (RICE) and the New Source Performance Standards (NSPS) for Stationary Internal Combustion Engines (ICE). The court vacated provisions in the regulations specifying that emergency engines could operate for emergency demand response or during periods where there is a deviation of voltage or frequency. This ministerial rule revises the RICE NESHAP and ICE NSPS to conform to the court's decision. 87 FR 60816 DDDDD National Emission Standards for Hazardous Air Pollutants for Major Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters 12/5/2022 This action finalizes amendments to the national emission standards for hazardous air pollutants (NESHAP) at major sources from new and existing industrial, commercial, and institutional (ICI) boilers and process heaters. Certain aspects of these standards were challenged and subsequently remanded to the Agency by the United States Court of Appeals for the District of Columbia Circuit (D.C. Circuit). This action finalizes amendments to several numeric emission limits for new and existing boilers and process heaters consistent with the court's opinion and sets compliance dates for these new emission limits. This action also provides further explanation of one aspect of the Agency's use of carbon monoxide (CO) as a surrogate for organic hazardous air pollutants (HAP) and its use of a CO threshold to represent the application of the maximum achievable control technology (MACT) for organic HAP. We are also finalizing several technical clarifications and corrections. 87 FR 78545 GGGGG National Emission Standards for Hazardous Air Pollutants: 12/22/2022 This action finalizes amendments to the national emission standards for hazardous air pollutants (NESHAP) for the site remediation source category. This action finalizes amendments to remove exemptions from the rule for site remediation activities performed under authority of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as a remedial action or a non- time-critical removal action, and for site remediation activities performed under Resource Conservation and Recovery Act (RCRA) corrective actions conducted at treatment, storage, and disposal facilities. 88 FR 10842 HHHHH National Emission Standards for Hazardous Air Pollutants: Miscellaneous Coating Manufacturing Technology Review 2/2/2023 The U.S. Environmental Protection Agency (EPA) is taking final action on the technology review conducted on the Miscellaneous Coating Manufacturing (MCM) source category regulated under the National Emission Standards for Hazardous Air Pollutants (NESHAP). These final amendments include provisions for inorganic hazardous air pollutant (HAP) standards for process vessels. 40 CFR Part 63 Summary of Relevant Updates from July 1, 2020-July 1, 2024 R307-214 Relevant Effective Rules and Regulations for National Emission Standards for Hazardous Air Pollutants for Source Categories, Incorporated through R307-214 88 FR 11556 PPPPPP New Source Performance Standards Review for Lead Acid Battery Manufacturing Plants and National Emission Standards for Hazardous Air Pollutants for Lead Acid Battery Manufacturing Area Sources Technology Review 2/23/2023 This action finalizes the results of the Environmental Protection Agency's (EPA's) review of the New Source Performance Standards (NSPS) for Lead Acid Battery Manufacturing Plants and the technology review for the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Lead Acid Battery Manufacturing Area Sources as required under the Clean Air Act (CAA). The EPA is finalizing revised lead emission limits for grid casting, paste mixing, and lead reclamation operations for both the area source NESHAP and under a new NSPS subpart (for lead acid battery manufacturing facilities that begin construction, reconstruction, or modification after February 23, 2022). In addition, the EPA is finalizing the following amendments for both the area source NESHAP and under the new NSPS subpart: performance testing once every 5 years to demonstrate compliance; work practices to minimize emissions of fugitive lead dust; increased inspection frequency of fabric filters; clarification of activities that are considered to be lead reclamation activities; electronic reporting of performance test results and semiannual compliance reports; and the removal of exemptions for periods of startup, shutdown, and malfunctions (SSM). The EPA is also finalizing a revision to the applicability provisions in the area source NESHAP such that facilities which make lead-bearing battery parts or process input material, including but not limited to grid casting facilities and lead oxide manufacturing facilities, will be subject to the area source NESHAP. In addition, the EPA is finalizing a requirement in the new NSPS for new facilities to operate bag leak detection systems for emission points controlled by a fabric filter that do not include a secondary fabric filter. 88 FR 13956 UUUUU National Emission Standards for Hazardous Air Pollutants: Coal- and Oil-Fired Electric Utility Steam Generating Units-Revocation of the 2020 Reconsideration and Affirmation of the Appropriate and Necessary Supplemental Finding 3/6/2023 After consideration of public comments, the EPA is revoking a May 22, 2020 finding that it is not appropriate and necessary to regulate coal- and oil-fired electric utility steam generating units (EGUs) under Clean Air Act (CAA) section 112, and concluding, as it did in its April 25, 2016 finding, that it remains appropriate and necessary to regulate hazardous air pollutant (HAP) emissions from EGUs after considering cost. 89 FR 16408 RRRRR National Emission Standards for Hazardous Air Pollutants: Taconite Iron Ore Processing 3/6/2024 The U.S. Environmental Protection Agency (EPA) is finalizing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Taconite Iron Ore Processing. Specifically, the EPA is finalizing maximum achievable control technology (MACT) standards for mercury (Hg) and establishing revised emission standards for hydrogen chloride (HCl) and hydrogen fluoride (HF).
