The Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) revisions related to volatile organic compound (VOC) reasonably available control technology (RACT), submitted by the Wisconsin Department of Natural Resources (``Wisconsin'' or ``WDNR'') on June 28, 2022. The SIP revisions consist of several additions, corrections, and clarifications to the Wisconsin Administrative Code (WAC) NR 400 series and update the VOC RACT requirements for the Miscellaneous Industrial Adhesives and Miscellaneous Metal and Plastic Parts Coatings Control Techniques Guidelines (CTG) source categories. Also, EPA is approving Wisconsin's August 10, 2022, request to remove three previously approved Administrative Orders from the SIP. The request to remove these Administrative Orders includes a Clean Air Act (CAA) Section 110(l) demonstration highlighting that the revisions to Wisconsin's rules do not interfere with any applicable requirement concerning attainment or any other applicable requirement of the CAA because this SIP revision is a direct replacement for the previously approved orders. These SIP revisions apply to nonattainment areas in Wisconsin classified as moderate or above under the 2008 or later ozone National Ambient Air Quality Standards (``NAAQS'' or ``standard''). These revisions are consistent with the CTG documents issued by EPA in 2008 and are approvable because they serve as SIP strengthening measures. EPA proposed to approve this action on January 30, 2023, and received no adverse comments.
The Environmental Protection Agency (EPA) is approving a revision to the New York State Implementation Plan (SIP) for the purposes of implementing controls of air pollution by particulate matter (PM).

The Agency will hold three public webinars and is accepting written feedback on establishing the new grant and technical assistance programs and a carbon labeling program for construction materials with substantially lower levels of embodied carbon.
The Environmental Protection Agency (EPA) is proposing to approve revisions to the Iowa State Implementation Plan (SIP) and the Operating Permit Program for the State of Iowa. The revisions require the electronic submittal of air emissions reporting, construction permit applications, and Title V permit applications, and make administrative updates. These revisions do not impact the stringency of the SIP or have an adverse effect on air quality. The EPA's proposed approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).
The Environmental Protection Agency (EPA) is finalizing a program to further reduce air pollution, including ozone and particulate matter (PM), from heavy-duty engines and vehicles across the United States. The final program includes new emission standards that are significantly more stringent and that cover a wider range of heavy-duty engine operating conditions compared to today's standards; further, the final program requires these more stringent emissions standards to be met for a longer period of when these engines operate on the road. Heavy-duty vehicles and engines are important contributors to concentrations of ozone and particulate matter and their resulting threat to public health, which includes premature death, respiratory illness (including childhood asthma), cardiovascular problems, and other adverse health impacts. The final rulemaking promulgates new numeric standards and changes key provisions of the existing heavy-duty emission control program, including the test procedures, regulatory useful life, emission-related warranty, and other requirements. Together, the provisions in the final rule will further reduce the air quality impacts of heavy-duty engines across a range of operating conditions and over a longer period of the operational life of heavy- duty engines. The requirements in the final rule will lower emissions of NO<INF>X</INF> and other air pollutants (PM, hydrocarbons (HC), carbon monoxide (CO), and air toxics) beginning no later than model year 2027. We are also finalizing limited amendments to the regulations that implement our air pollutant emission standards for other sectors (e.g., light-duty vehicles, marine diesel engines, locomotives, and various other types of nonroad engines, vehicles, and equipment).
The Environmental Protection Agency (EPA) has submitted an information collection request (ICR), Prevention of Significant Deterioration and Nonattainment New Source Review (EPA ICR Number 1230.34, OMB Control Number 2060-0003), to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act. This is a proposed extension of the ICR, which is currently approved through January 31, 2023. Public comments were previously requested via the Federal Register on April 8, 2022, during a 60-day comment period. This notice allows for 30 days for public comments.
The Environmental Protection Agency (EPA) is approving, under the Clean Air Act (CAA), a request submitted by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) on December 18, 2020, to revise the Michigan State Implementation Plan (SIP). EGLE's submittal addresses the emissions inventory and statement requirements for the Allegan County, Berrien County, Detroit (Livingston, Macomb, Monroe, Oakland, St. Clair, Washtenaw, and Wayne Counties) and Muskegon County nonattainment areas under the 2015 ozone National Ambient Air Quality Standard (NAAQS or standard). The CAA requires states to develop and submit, as SIP revisions, emission inventories for all ozone nonattainment areas. In this action, EPA is approving EGLE's emissions inventories for the Allegan County, Berrien County, and Muskegon County nonattainment areas under the 2015 ozone NAAQS and the removal of the repealed Act 348, Section 14a. EPA approved the portions of EGLE's December 18, 2020, submittal pertaining to the certification of EGLE's stationary annual emissions statement regulation and emissions inventories for the Detroit nonattainment area under the 2015 ozone NAAQS in a separate action on July 6, 2022.

The Indian Wells Second Maintenance Plan includes, among other elements, a base year emissions inventory, a maintenance demonstration, contingency provisions, and motor vehicle emissions budgets for use in transportation conformity determinations. The EPA is finalizing these actions because the SIP revision meets the applicable statutory and regulatory requirements for such plans and motor vehicle emissions budgets.
The Environmental Protection Agency (EPA) is taking final action to approve a revision to the San Diego County Air Pollution Control District's (SDCAPCD or ``District'') portion of the California State Implementation Plan (SIP). This revision concerns a negative declaration for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS) in the ozone nonattainment area under the jurisdiction of the SDCAPCD and one volatile organic compound (VOC) rule covering transfer of organic compounds into mobile transport trucks. We are approving a local rule to regulate these emission sources under the Clean Air Act (CAA or ``the Act'') and the negative declaration. We are also correcting sections in the Code of Federal Regulations (CFR) to reflect the current status of certain provisions of the California SIP.
The Environmental Protection Agency (EPA or the ``Agency'') is proposing approval of a request submitted by the Colorado Department of Public Health and Environment (CDPHE) on June 27, 2022 for delegation of authority to implement and enforce Federal Plan Requirements for Hospital/Medical/Infectious Waste Incinerators (HMIWI) Constructed On or Before December 1, 2008 (the Federal Plan), within the state of Colorado. The Federal Plan establishes emission limits and monitoring, operating, and recordkeeping requirements for HMIWI units constructed on or before December 1, 2008, or modified on or before April 6, 2010. A Memorandum of Agreement (MOA) was signed on July 21, 2022 by the CDPHE Air Pollution Control Division Director, Michael Ogletree. This MOA constitutes the mechanism for the transfer of authority from the EPA to CDPHE. The MOA became effective upon signature by Regional Administrator, KC Becker, on August 8, 2022. The MOA delineates policies, responsibilities, and procedures by which the Federal plan will be administered and enforced by the CDPHE, as well as the authorities retained by EPA. The MOA and the request letter are included in the docket for this action. Accordingly, EPA is proposing to approve CDPHE's submittal in accordance with the Clean Air Act (CAA).
The EPA is taking final action finding that the state of California has failed to submit state implementation plan (SIP) revisions for the Sacramento Metro nonattainment area to satisfy certain requirements of the Clean Air Act (CAA) for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS). Specifically, these requirements pertain to the assessment and collection of fees under CAA section 185. This action triggers certain CAA deadlines for the imposition of sanctions if California does not submit the required SIP revisions within the specified timeframes. This finding also establishes a CAA deadline for the EPA to promulgate federal implementation plans (FIPs) to address the CAA section 185 requirements if the State does not submit or the EPA does not approve the State's section 185 SIP revisions.
On December 1, 2022, the U.S. Environmental Protection Agency (EPA) proposed a rule titled ``New Source Performance Standards Review for Secondary Lead Smelters.''

The comment period will now remain open until February 1, 2023, to allow additional time for stakeholders and Tribal Nations to review and comment on the proposal.
The Environmental Protection Agency (EPA) is finalizing approval of a state implementation plan (SIP) revision submitted by the State of North Carolina, through the North Carolina Department of Environment Quality, Division of Air Quality (DAQ), via a letter dated December 9, 2021. The SIP revision includes the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS) Limited Maintenance Plan (LMP) for the North Carolina portion (hereinafter referred to as the Metrolina Area) of the Charlotte-Gastonia-Rock Hill NC-SC 1997 8-hour ozone maintenance area (hereinafter referred to as the ``Charlotte NC- SC 1997 8-hour NAAQS Area'' or ``bi-state Charlotte Area''). The Charlotte NC-SC 1997 8-hour NAAQS Area is comprised of Cabarrus, Gaston, Lincoln, Mecklenburg, Rowan and Union Counties and a portion of Iredell County (i.e., Davidson and Coddle Creek Townships) in North Carolina; and the Rock Hill Metropolitan Planning Organization boundary in York County, South Carolina. EPA is finalizing approval because the LMP provides for the maintenance of the 1997 8-hour ozone NAAQS within the Metrolina Area through the end of the second 10-year portion of the maintenance period. This action makes certain commitments related to maintenance of the 1997 8-hour ozone NAAQS in the Metrolina Area federally enforceable as part of the North Carolina SIP.
The Environmental Protection Agency (EPA) is finalizing the approval of a revision to the North Carolina State Implementation Plan (SIP) submitted by the North Carolina Department of Environmental Quality (NCDEQ), Division of Air Quality, via a letter dated April 13, 2021, and received by EPA on April 14, 2021.

The intended effect of this action is to propose approval of the amended Asbestos Disposal Site Rule in place of the Asbestos NESHAP provisions for inactive waste disposal sites not operated after July 9, 1981. This approval would make the New Hampshire Department of Environmental Services' (NH DES) amended Asbestos Disposal Site Rule federally enforceable. This action is being taken under the Clean Air Act.
The Environmental Protection Agency (EPA) is determining that the Imperial County, California fine particulate matter (PM<INF>2.5</INF>) nonattainment area (``Imperial PM<INF>2.5</INF> nonattainment area'') attained the 2012 annual PM<INF>2.5</INF> national ambient air quality standards (NAAQS or ``standard'') by its December 31, 2021 ``Moderate'' area attainment date. This determination is based upon ambient air quality monitoring data from 2019 through 2021. We are also making a clean data determination (CDD) based on our determination that preliminary air quality monitoring data from 2022 indicate the Imperial PM<INF>2.5</INF> nonattainment area continues to attain the 2012 annual PM<INF>2.5</INF> NAAQS. As a result of this CDD, certain Clean Air Act (CAA) requirements that apply to the Imperial County Air Pollution Control District (ICAPCD or ``District'') are suspended for so long as the area continues to meet the 2012 annual PM<INF>2.5</INF> NAAQS. The area remains nonattainment for the 2012 annual PM<INF>2.5</INF> NAAQS until the area is redesignated to attainment. The EPA is also approving a revision to California's state implementation plan (SIP) consisting of the 2012 base year emissions inventory for the Imperial PM<INF>2.5</INF> nonattainment area, submitted by the California Air Resources Board (CARB or ``State'') on July 18, 2018.
The Environmental Protection Agency (EPA) is promulgating this final rule to adjust the level of the maximum (and minimum) statutory civil monetary penalty amounts under the statutes the EPA administers. This action is mandated by the Federal Civil Penalties Inflation Adjustment Act of 1990, as amended through the Federal Civil Penalties Inflation Adjustment Act Improvements Act of 2015 (``the 2015 Act''). The 2015 Act prescribes a formula for annually adjusting the statutory maximum (and minimum) amount of civil monetary penalties to reflect inflation, maintain the deterrent effect of statutory civil monetary penalties, and promote compliance with the law. The rule does not establish specific civil monetary penalty amounts the EPA may seek in particular cases, as appropriate given the facts of particular cases and applicable agency penalty policies. The EPA's civil penalty policies, which guide enforcement personnel on how to exercise the EPA's discretion within statutory penalty authorities, take into account a number of fact-specific considerations, e.g., the seriousness of the violation, the violator's good faith efforts to comply, any economic benefit gained by the violator as a result of its noncompliance, and the violator's ability to pay.
The Environmental Protection Agency (EPA) is finalizing the approval of a State Implementation Plan (SIP) revision, submitted by North Carolina on April 13, 2021. Specifically, EPA is approving updates to the incorporation by reference of Federal new source review (NSR) regulations and federal guidelines on air quality modeling in the North Carolina SIP. EPA is also converting a previous conditional approval regarding the infrastructure SIP prevention of significant deterioration (PSD) elements, for the 2015 ozone national ambient air quality standards (NAAQS) for North Carolina to a full approval. EPA is also approving updates to North Carolina's NSR regulations to better align them with the federal rules. EPA is approving these changes pursuant to the Clean Air Act (CAA or Act).
The Environmental Protection Agency (EPA or Agency) is determining that the Las Vegas, Nevada nonattainment area (``Las Vegas'') failed to attain the 2015 ozone National Ambient Air Quality Standard (NAAQS) by the applicable attainment date. The effect of failing to attain by the applicable attainment date is that Las Vegas is being reclassified by operation of law as ``Moderate'' nonattainment for the 2015 ozone NAAQS on January 5, 2023, the effective date of this final rule. Accordingly, the Nevada Division of Environmental Protection (NDEP) must submit State Implementation Plan (SIP) revisions and implement controls to satisfy the statutory and regulatory requirements for Moderate areas for the 2015 ozone NAAQS according to the deadlines established in this final rule.
The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants for Lime Manufacturing Plants (Lime Manufacturing NESHAP), as required by the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is taking final action to disapprove revisions to the Missouri State Implementation Plan (SIP) submitted by Missouri on March 7, 2019. In its submission, Missouri requested rescinding a regulation addressing sulfur compounds from the SIP and replacing it with a new regulation that establishes requirements for units emitting sulfur dioxide (SO<INF>2</INF>). The EPA is disapproving the SIP revision because the state has not demonstrated that the removal of SO<INF>2</INF> emission limits for the Evergy-Hawthorn (Hawthorn, formerly Kansas City Power & Light-Hawthorn) and Ameren Labadie (Labadie) power plants from the SIP would not interfere with National Ambient Air Quality Standard (NAAQS) attainment and reasonable further progress (RFP), or any other applicable requirement of the Clean Air Act (CAA). This disapproval action is being taken under the CAA to maintain the stringency of the SIP and preserve air quality.

The Environmental Protection Agency (EPA) is taking final action to find that the State of California has failed to submit State Implementation Plan (SIP) revisions to satisfy the contingency measures requirements of the Clean Air Act (CAA) for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS or ``standards'') for both the Riverside County (Coachella Valley), California (``Coachella Valley'') and Los Angeles-San Bernardino Counties (West Mojave Desert), California (``West Mojave Desert'') nonattainment areas. Under the CAA and the EPA's implementing regulations, by July 20, 2016, California was required to submit, among other SIP revisions, contingency measures for the Coachella Valley and West Mojave Desert nonattainment areas to be triggered if the areas fail to attain or fail to meet reasonable further progress (RFP). The State submitted the required SIP revisions, but subsequently withdrew the contingency measures portion. This finding establishes a 2-year deadline for the EPA to promulgate Federal Implementation Plans (FIPs) to address the contingency measure requirements for these areas, unless, prior to the EPA promulgating FIPs, California submits, and the EPA approves, SIP revisions that meet these requirements. The CAA also provides for the imposition of sanctions if California does not submit the required SIP revisions within timeframes specified by the CAA.

These revisions do not interfere with attainment or maintenance of any National Ambient Air Quality Standard (NAAQS), reasonable further progress, or other Clean Air Act (CAA) requirements. Approval of these revisions will ensure consistency between state and federally approved rules.
The Environmental Protection Agency (EPA) is approving three elements of a State Implementation Plan (SIP) revision, which was submitted by the State of Rhode Island on December 6, 2017. This revision addressed the infrastructure requirements of the Clean Air Act (CAA or the Act) for the 2012 annual fine particle (PM<INF>2.5</INF>) National Ambient Air Quality Standard (NAAQS). On May 31, 2022, EPA approved much of the submission, but did not act on three elements related to the infrastructure requirement to have a comprehensive Prevention of Significant Deterioration (PSD) program. In today's action, EPA is approving the three remaining elements of the state's December 2017 infrastructure SIP submittal based on a previous EPA approval of Rhode Island's Air Pollution Control Regulation (APCR) No. 9. This action is being taken in accordance with the Clean Air Act.
Notice is hereby given that the Environmental Protection Agency (EPA) has determined that, in accordance with the provisions of the Federal Advisory Committee Act (FACA), the National Environmental Justice Advisory Council (NEJAC) is necessary and in the public interest in connection with the performance of duties imposed on the agency by law. Accordingly, NEJAC will be renewed for an additional two-year period. The purpose of the NEJAC is to provide advice and recommendations to the Administrator about issues associated with integrating environmental justice concerns into EPA's outreach activities, public policies, science, regulatory, enforcement, and compliance decisions.
The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the Commonwealth of Virginia. The revision provides Virginia's determination for the 2015 Ozone national ambient air quality standards (NAAQS), via a negative declaration, that there are no sources within the Northern Virginia volatile organic compound (VOC) Emissions Control Area subject to EPA's 2016 Oil and Natural Gas control techniques guidelines (2016 Oil and Gas CTG). The negative declaration covers only the 2016 Oil and Gas CTG and asserts that there are no sources subject to this CTG located in the Northern Virginia VOC Emissions Control Area. EPA is approving these revisions to the Virginia SIP in accordance with the requirements of the Clean Air Act (CAA).
The Environmental Protection Agency (EPA or the Agency) is disapproving State Implementation Plan (SIP) submissions from New York and New Jersey addressing interstate transport for the 2008 8-hour ozone national ambient air quality standards (NAAQS). The ``good neighbor'' or ``interstate transport'' provision of the Clean Air Act (CAA) requires that each state's SIP contain adequate provisions to prohibit emissions from within the state from significantly contributing to nonattainment or interfering with maintenance of the NAAQS in other states. This requirement is part of the broader ``infrastructure'' requirements, which are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA.
The Environmental Protection Agency (EPA) is taking final action to approve revisions to the State Implementation Plan (SIP) and Operating Permit Program for the State of Iowa. This final action will amend the SIP to update incorporations by reference to EPA methods for measuring air pollutant emissions, performance testing (stack testing) and continuous monitoring. These revisions do not impact the stringency of the SIP or have an adverse effect on air quality. The EPA's approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Montana on March 25, 2020, addressing regional haze. Specifically, EPA is proposing to approve a SIP revision for the first implementation period of the Clean Air Act's (CAA) regional haze program that addresses the nitrogen oxides (NO<INF>X</INF>) and sulfur dioxide (SO<INF>2</INF>) Best Available Retrofit Technology (BART) requirements for two electric generating unit (EGU) facilities, as well as proposing to withdraw portions of the Federal Implementation Plan (FIP) promulgated by EPA in 2012 (2012 regional haze FIP) addressing the NO<INF>X</INF>, SO<INF>2</INF> and particulate matter (PM) BART requirements for two cement kilns and the PM BART requirements for the same two EGU facilities. This action also addresses the United States Court of Appeals for the Ninth Circuit's June 9, 2015 vacatur and remand of portions of the FIP. EPA is proposing this action pursuant to sections 110 and 169A of the CAA.

Under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (``CERCLA'' or ``Superfund''), the Environmental Protection Agency (EPA or the Agency) is proposing to designate perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), including their salts and structural isomers, as hazardous substances. CERCLA authorizes the Administrator to promulgate regulations designating as hazardous substances such elements, compounds, mixtures, solutions, and substances which, when released into the environment, may present substantial danger to the public health or welfare or the environment. Such a designation would ultimately facilitate cleanup of contaminated sites and reduce human exposure to these ``forever'' chemicals.
EPA is finalizing an optional alternative renewable identification number (RIN) retirement schedule for small refineries under the Renewable Fuel Standard (RFS) program for the 2020 compliance year. Small refineries that elect to use the alternative RIN retirement schedule will have to fully comply with their 2020 RFS obligations-- including any RIN deficits from 2019 carried forward into the 2020 compliance year--by February 1, 2024. EPA is taking this action because small refineries may need more time to plan for compliance with their RFS obligations given EPA's delay in deciding small refinery exemption (SRE) petitions and setting the associated compliance deadlines.
On November 23, 2016, the Environmental Protection Agency (EPA) issued a final rule titled ``Approval and Promulgation of Implementation Plans; State of Arizona; Revised Format for Materials Incorporated by Reference.'' That publication inadvertently omitted an entry for a regulation approved as part of the Maricopa County portion of the Arizona State Implementation Plan (SIP) and contained certain other errors. The EPA is proposing to correct this omission and to correct the other errors. The regulations affected by this correcting amendment have all been previously submitted by the State of Arizona and approved by the EPA.
The Environmental Protection Agency (EPA) is proposing to amend its Risk Management Program (RMP) regulations as a result of Agency review. The proposed revisions include several changes and amplifications to the accident prevention program requirements, enhancements to the emergency preparedness requirements, increased public availability of chemical hazard information, and several other changes to certain regulatory definitions or points of clarification. These proposed amendments seek to improve chemical process safety; assist in planning, preparedness, and responding to RMP-reportable accidents; and improve public awareness of chemical hazards at regulated sources.
The Environmental Protection Agency (EPA) is promulgating a Federal implementation plan (FIP) for the Commonwealth of Pennsylvania (Pennsylvania or the Commonwealth). This FIP sets emission limits for nitrogen oxides (NO<INF>X</INF>) emitted from coal-fired electric generating units (EGUs) equipped with selective catalytic reduction (SCR) in Pennsylvania in order to meet the reasonably available control technology (RACT) requirements for the 1997 and 2008 ozone national ambient air quality standards (NAAQS). This action is being taken in accordance with the requirements of the Clean Air Act (CAA).
The Environmental Protection Agency (EPA) is taking final action finding that 15 states have failed to submit State Implementation Plans (SIPs) to satisfy the visibility protection requirements of the Clean Air Act (CAA), as described in implementing regulations, for the regional haze second planning period. These findings of failure to submit establish a 2-year deadline for the EPA to promulgate Federal Implementation Plans (FIPs) to address these requirements for a given state unless, prior to the EPA promulgating a FIP, the state submits, and the EPA approves, a SIP that meets these requirements.
The Environmental Protection Agency (EPA) has submitted an information collection request (ICR), ``Renewable Fuel Standard (RFS) Program'' (EPA ICR Number 2546.03, OMB Control Number 2060-0725) to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act. This is a proposed extension of the ICR, which is currently approved through August 31, 2022. Public comments were previously requested via the Federal Register on February 11, 2022, during a 60-day comment period. This notice allows for an additional 30 days for public comments. A fuller description of the ICR is given below, including its estimated burden and cost to the public. 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.
Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision from the New Mexico Environment Department (NMED) submitted on October 17, 2016, on behalf of the Albuquerque-Bernalillo County Air Quality Control Board (Air Board). The submittal is in response to the EPA's national SIP call on June 12, 2015, concerning excess emissions during periods of Startup, Shutdown, and Malfunction (SSM). EPA is approving the SIP submittal and finds that the SIP revision corrects the substantial inadequacies identified in the June 12, 2015, SIP call.
