Reclassification of Major Sources as Area Sources Under
Section 112 of the Clean Air Act.
1/19/2021 This rule finalizes amendments to the General Provisions that apply to National
Emission Standards for Hazardous Air Pollutants (NESHAP). 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.

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
