The Environmental Protection Agency (EPA) is proposing to approve two State Implementation Plan (SIP) revisions submitted by the Commonwealth of Kentucky, through the Energy and Environment Cabinet (Cabinet), Division of Air Quality (DAQ) on January 26, 2024, and February 15, 2024, to certify two requirements under the Clean Air Act (CAA or Act). These revisions establish that the Kentucky SIP satisfies the nonattainment new source review (NNSR) and base year emissions inventory requirements for the 2010 1-hour sulfur dioxide (SO<INF>2</INF>) national ambient air quality standard (NAAQS) for the Henderson-Webster SO<INF>2</INF> nonattainment area (hereinafter "Henderson-Webster SO<INF>2</INF> Nonattainment Area" or "Area"). These actions are being proposed pursuant to the CAA.
The Environmental Protection Agency (EPA) is approving the regional haze state implementation plan (SIP) revision submitted by California on August 9, 2022 (hereinafter the "2022 California Regional Haze Plan" or "the Plan"), under the Clean Air Act (CAA) and the EPA's Regional Haze Rule (RHR) for the program's second implementation period. The Plan addresses the requirement that states must periodically revise their long-term strategies for making reasonable progress towards the national goal of preventing any future, and remedying any existing, anthropogenic impairment of visibility, including regional haze, in mandatory Class I Federal areas. The Plan also addresses other applicable requirements for the second implementation period of the regional haze program. The EPA is taking this action pursuant to CAA sections 110 and 169A.
Pursuant to the Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Arkansas through the Division of Environmental Quality (DEQ) on August 8, 2022, and clarified by DEQ on July 29, 2025, as satisfying the requirements of the Act and the EPA's Regional Haze Rule (RHR) for visibility protection in mandatory Class I Federal areas (Class I areas) for the program's second implementation period. Arkansas' SIP submission addresses the requirement that states must revise their long-term strategies for making reasonable progress to prevent any future and remedy any existing man-made visibility impairment in the Class I areas. The EPA is taking this action pursuant to sections 110 and 169A of the CAA.
With this direct final rule, the Environmental Protection Agency (EPA) is promulgating approval of revisions to the Clean Air Act Operating Permit Program (title V) of the San Diego County Air Pollution Control District (SDCAPCD or "District") in California. The EPA is taking this final action in accordance with federal regulations and the Clean Air Act (CAA or "Act").
On May 16, 2025, the United States Court of Appeals for the Fifth Circuit (the Court) granted petitions for review of the EPA's nonattainment area designation for the Rusk and Panola Counties area, Texas for the 2010 SO<INF>2</INF> National Ambient Air Quality Standard (NAAQS). Accordingly, that nonattainment designation for the area has been vacated. The vacatur of the nonattainment designation necessarily requires the withdrawal of two contingent actions since the underlying designation is no longer valid: EPA's finding of failure to submit an attainment plan (FFS) issued on August 10, 2020, and EPA's finding of failure to attain the NAAQS by the attainment date (FFA) issued on December 17, 2024. The EPA is withdrawing these two final actions in accordance with the court's decision and finds that any requirements deriving from either the FFS or the FFA are no longer applicable.
This document announces the Agency's receipt of and solicits public comment on initial filings of pesticide petitions requesting the establishment or modification of regulations for residues of pesticide chemicals in or on various commodities.

The United States Environmental Protection Agency (the EPA or Agency) is withdrawing the proposed rule entitled "Clean Water Act Effluent Limitations Guidelines and Standards for the Meat and Poultry Products Point Source Category," which published in the Federal Register on January 23, 2024. After considering public comments on the proposed rule, the EPA has decided not to finalize revised technology- based effluent limitations guidelines (ELGs) or pretreatment standards for the Meat and Poultry Products (MPP) industry, based on exercise of its statutory discretion and judgment that such revisions would not be appropriate.
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Georgia through the Georgia Environmental Protection Division (EPD) on June 27, 2024. The revision seeks to remove permitting requirements related to nonattainment, including nonattainment new source review (NNSR), from Georgia's SIP as obsolete, remove certain provisions related to the use of emission reduction credits (ERCs), and make other changes based upon the lack of any areas designated as nonattainment for the National Ambient Air Quality Standards (NAAQS) in Georgia. EPA is proposing to approve these changes pursuant to the Clean Air Act (CAA or Act).
The Environmental Protection Agency (EPA or the Agency) is proposing to approve the Wyoming coal combustion residuals (CCR) permit program under the Resource Conservation and Recovery Act (RCRA). After reviewing the CCR permit program application submitted by the Wyoming Department of Environmental Quality (WDEQ), EPA has preliminarily determined that Wyoming's CCR permit program meets the standard for partial approval under RCRA. If approved, Wyoming's CCR permit program will operate in lieu of the Federal CCR program with the exception of the specific provisions noted below. EPA is seeking comment on this proposal during a 60-day public comment period and will hold a hybrid in-person and online public hearing on EPA's preliminary approval of Wyoming's partial CCR permit program.

The EPA is also making additional administrative updates to the MDAQMD portion of the California SIP by correcting text in the Code of Federal Regulations.
The Environmental Protection Agency (EPA) is proposing to approve regulatory amendments that revise two previous program approvals from the Connecticut Department of Energy and Environmental Protection (CT DEEP). The revisions include amendments to the Regulations of Connecticut State Agencies (RCSA) that revise the Connecticut State Operating Permit Program and amendments to RCSA that revise limitations on potential to emit Clean Air Act (CAA) pollutants. A significant aspect of this action involves revising the definition of "hazardous air pollutant" in the RCSA in response to EPA adding 1- bromopropane to the list of hazardous air pollutants. This action is being taken under the Clean Air Act.
The Environmental Protection Agency (EPA) is proposing to approve revisions to Ohio Administrative Code (OAC) Chapters 3745-21 and 3745-110 into the Ohio State Implementation Plan (SIP). The Ohio Environmental Protection Agency ("Ohio" or "Ohio EPA") submitted these revisions on March 30, 2022, and supplemented the submittal on February 1, 2023, and August 28, 2023. EPA is proposing to approve parts of OAC Chapters 3745-21 and 3745-110 as satisfying some of the Moderate Volatile Organic Compound (VOC) Reasonably Available Control Technology (RACT) and Nitrogen Oxide (NO<INF>x</INF>) RACT requirements for the Cleveland, OH nonattainment area (Cuyahoga, Geauga, Lake, Lorain, Medina, Portage, and Summit counties) under the 2015 ozone National Ambient Air Quality Standard ("NAAQS" or "standard"). Finally, EPA is proposing to approve OAC rule 3745-15-03, submitted by Ohio on February 9, 2023, and supplemented on December 1, 2023, and December 30, 2024.
The U.S. Environmental Protection Agency (EPA) is finalizing, pursuant to the statutory framework established in the American Innovation and Manufacturing Act of 2020 (AIM Act), the eligibility of six applications to continue to receive priority access to allowances to produce or import hydrofluorocarbons. In this final rule, EPA establishes the framework for how EPA interprets the statutory criteria for assessing whether to renew the eligibility of applications to receive application-specific allowances and sets out determinations to renew or not renew each of the six applications that currently receive application-specific allowances. EPA is also finalizing revisions to the Technology Transitions regulations relevant to the specific applications under review, a procedural process for submitting a petition to designate a new application as eligible for priority access to allowances, the methodology used to allocate allowances to application-specific allowance holders for calendar years 2026 and beyond, and limited revisions to existing regulations. In addition, EPA is authorizing an entity to produce regulated substances for export. Lastly, EPA is finalizing certain regulatory confidentiality determinations for newly reported information.
The U.S. Environmental Protection Agency (EPA) is taking interim final action to provide for the temporary use of incineration units subject to commercial and industrial solid waste incinerator (CISWI) regulations during disaster recovery. Currently, only other solid waste incinerators (OSWI) are authorized to combust debris from a disaster or emergency on a temporary basis without having to comply with applicable Clean Air Act (CAA) section 129 requirements. We are also authorizing such temporary use for incinerators (including air curtain incinerators (ACI)) subject to CISWI regulations by adding temporary-use provisions that essentially mirror those in the OSWI regulations to existing Federal CISWI rule subparts. The EPA is requesting comments on all aspects of this interim final rule and will consider all comments received after the conclusion of the comment period.
The U.S. Environmental Protection Agency (EPA) is proposing to partially approve and partially disapprove or, in the alternative, to fully approve a submission by the State of California to revise its State Implementation Plan (SIP) relating to the control of emissions from non-gasoline combustion vehicles over 14,000 pounds. EPA is proposing to disapprove the State's "Heavy-Duty Inspection and Maintenance Regulation" to the extent it applies to vehicles registered out-of-state or out-of-country. The EPA has substantial concerns that the State has not provided adequate assurances under Clean Air Act (CAA) section 110(a)(2)(E)(i) that implementation of the SIP is not prohibited by Federal law. EPA seeks comment on this and other aspects of this proposed rule. If finalized as a partial approval and partial disapproval, this rule would allow certain aspects of the covered State regulations to go into effect and would not trigger CAA section 179 sanctions because the submittal is not a required submission under CAA section 110(a)(2). If finalized as an approval, this rule would allow all covered State regulations to go into effect.
The Environmental Protection Agency is taking final action to approve a state plan submitted by the State of Florida, through the Florida Department of Environmental Protection (FDEP) on May 31, 2017, that was supplemented on December 19, 2017, and February 2, 2018, for implementing and enforcing the Emissions Guidelines (EG) applicable to existing Commercial and Industrial Solid Waste Incineration (CISWI) units. The State plan provides for implementation and enforcement of the EG, as finalized by the EPA on February 7, 2013, and amended on June 23, 2016, applicable to existing CISWI units for which construction commenced on or before June 4, 2010, or for which modification or reconstruction commenced after June 4, 2010, but no later than August 7, 2013. The Florida State plan establishes emission limits, monitoring, operating, recordkeeping, and reporting requirements for affected CISWI units.
The Environmental Protection Agency (EPA) is correcting a document that appeared in the Federal Register (FR) on August 15, 2025. The EPA finalized the document announcing three public hearings and comment period extensions for the following rules: Extension of Deadlines: Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for Existing Sources: Oil and Natural Gas Sector Climate Review Interim Final Rule; National Emission Standards for Hazardous Air Pollutants for Integrated Iron and Steel Manufacturing Facilities; National Emission Standards for Hazardous Air Pollutants for Coke Ovens: Pushing, Quenching, and Battery Stacks, and Coke Oven Batteries. Following publication of this document, the EPA discovered inadvertent errors in the comment period extension dates for the Oil and Natural Gas and Iron and Steel rulemakings and is correcting them in this action.
The Environmental Protection Agency (EPA) is proposing to redesignate the nonattainment area in Muscatine County, Iowa to attainment for the 2010 1-hour sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standard (NAAQS). The EPA is also proposing to approve Iowa's maintenance plan for the 2010 1-hour SO<INF>2</INF> NAAQS for the Muscatine nonattainment area and approve modifications to source-specific permits in the Iowa State Implementation Plan (SIP). 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 updating the materials that are incorporated by reference (IBR) into the Washington State Implementation Plan (SIP). The regulations affected by this update have been previously submitted by Washington and approved by the EPA. This update affects the materials that are available for public inspection at the National Archives and Records Administration (NARA) and the EPA Regional Office.
The EPA is notifying the public that we have found the motor vehicle emissions budgets for the Klamath Falls, Oregon 2006 24-hour fine particulate matter standard nonattainment area adequate for transportation conformity purposes. The budgets were submitted on August 20, 2024, as part of Oregon's Klamath Falls Redesignation Request and Maintenance Plan. As a result of our finding, the Klamath Falls area must use these budgets for future transportation conformity determinations.
The Environmental Protection Agency (EPA) is finalizing our determination that the Sacramento Metro, California area attained the 2008 8-hour ozone national ambient air quality standards (NAAQS) by its December 31, 2024 attainment date. This determination is based on quality-assured and certified ambient air quality monitoring data from 2022 through 2024. We are also finalizing a determination that the requirement for the State to have contingency measures for reasonable further progress (RFP) and attainment for the 2008 ozone NAAQS no longer applies for this area.
