The Environmental Protection Agency (EPA) is taking final action to approve the Regional Haze State Implementation Plan (SIP) for the State of Iowa as satisfying applicable requirements under the Clean Air Act (CAA) and EPA's Regional Haze Rule (RHR) for the program's second implementation period. Iowa's SIP submission 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 SIP submission also addresses other applicable requirements for the second implementation period of the regional haze program. The EPA is taking this action pursuant to the CAA.
In this action, the U.S. Environmental Protection Agency (EPA) is proposing to repeal all greenhouse gas (GHG) emission standards for light-duty, medium-duty, and heavy-duty vehicles and engines to effectuate the best reading of Clean Air Act (CAA) section 202(a). We propose that CAA section 202(a) does not authorize the EPA to prescribe emission standards to address global climate change concerns and, on that basis, propose to rescind the Administrator's prior findings in 2009 that GHG emissions from new motor vehicles and engines contribute to air pollution which may endanger public health or welfare. We further propose, in the alternative, to rescind the Administrator's prior findings in 2009 because the EPA unreasonably analyzed the scientific record and because developments cast significant doubt on the reliability of the findings. Lastly, we propose to repeal all GHG emission standards on the alternative bases that no requisite technology for vehicle and engine emission control can address the global climate change concerns identified in the findings without risking greater harms to public health and welfare.
The Environmental Protection Agency (EPA) is announcing a virtual public hearing to be held August 19 and 20, 2025, on its proposal for the "Reconsideration of 2009 Endangerment Finding and Greenhouse Gas Vehicle Standards," which was signed on July 29, 2025. An additional session will be held on August 21, 2025 if necessary, to accommodate the number of testifiers that sign up to testify. EPA is proposing to rescind EPA's 2009 Greenhouse Gas Endangerment Finding and repeal all greenhouse gas (GHG) emission standards for light-duty, medium-duty, and heavy-duty vehicles and engines.
The Environmental Protection Agency (EPA) is proposing to approve, under the Clean Air Act (CAA), the limited maintenance plan (LMP) for the 2006 PM<INF>2.5</INF> national ambient air quality standard (NAAQS) for the New Jersey portion of both of New Jersey's multi-state maintenance areas: the Northern New Jersey portion of the New York-Northern New Jersey-Long Island, NY-NJ-CT (Northern New Jersey) maintenance area and the New Jersey portion of the Philadelphia-Wilmington, PA-NJ-DE (Southern New Jersey) maintenance area. This LMP was submitted on July 6, 2023, and supplemented on June 6, 2024, by the New Jersey Department of Environmental Protection (NJDEP). The plan addresses the second 10-year maintenance period for particulate matter with an aerodynamic diameter less than or equal to a nominal 2.5 micrometers, known as PM<INF>2.5</INF>. The EPA is proposing approval of New Jersey's LMP submission because it provides for the maintenance of the 2006 24-hour PM<INF>2.5</INF> NAAQS through the end of the second 10-year portion of the maintenance period. In addition, the EPA completed the adequacy review process of this New Jersey PM<INF>2.5</INF> LMP for transportation conformity purposes on June 7, 2024.
The U.S. Environmental Protection Agency (EPA) is taking interim final action to extend certain deadlines within the final rule titled "Standards of Performance for New, Reconstructed, and Modified Sources and Emissions Guidelines for Existing Sources: Oil and Natural Gas Sector Climate Review," 89 FR 16820 (March 8, 2024) (hereafter "2024 final rule"). Specifically, the EPA is extending deadlines for certain provisions related to control devices, equipment leaks, storage vessels, process controllers, and covers/closed vent systems in "Subpart OOOOb--Standards of Performance for Crude Oil and Natural Gas Facilities for Which Construction, Modification or Reconstruction Commenced After December 6, 2022" (NSPS OOOOb). The EPA also is extending the date for future implementation of the SuperEmitter Program. Finally, the EPA is extending the state plan submittal deadline in "Subpart OOOOc--Emissions Guidelines (EG) for Greenhouse Gas Emissions From Existing Crude Oil and Natural Gas Facilities" (EG OOOOc). The EPA is requesting comments on all aspects of this interim final rule and will consider all comments received in determining whether amendments to this rule are appropriate after the conclusion of the comment period.
The Environmental Protection Agency (EPA) is proposing to approve a revision to the South Coast Air Quality Management District (SCAQMD) portion of the California State Implementation Plan (SIP) concerning a rule submitted to address section 185 of the Clean Air Act (CAA or "Act") with respect to the 1997 and 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS or "standard").

The Environmental Protection Agency (EPA) is proposing to approve a regional haze State Implementation Plan (SIP) revision submitted by the South Carolina Department of Health and Environmental Control (DHEC) dated March 3, 2022, as satisfying the applicable requirements under the Clean Air Act (CAA or Act) and EPA's Regional Haze Rule (RHR) for the program's second planning period. South Carolina's SIP submission addresses the requirement that states must periodically revise their long-term strategies for making reasonable progress toward 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 SIP submission also addresses other applicable requirements for the second planning period of the regional haze program. EPA is proposing this action pursuant to sections 110 and 169A of the Act.
The Environmental Protection Agency (EPA) is determining that Indian country under the jurisdiction of the Shinnecock Indian Nation located within the New York-Northern New Jersey-Long Island nonattainment area (Shinnecock Indian Nation area) failed to attain the 2015 ozone National Ambient Air Quality Standards (NAAQS) by the applicable attainment date. The effect of failing to attain by the applicable attainment date is that the area will be reclassified by operation of law to "Serious" nonattainment for the 2015 ozone NAAQS on September 2, 2025, the effective date of this final rule. This action fulfills the EPA's obligation under the Clean Air Act (CAA) to determine whether ozone nonattainment areas attained the NAAQS by the attainment date and to publish a document in the Federal Register identifying each area that is determined as having failed to attain and identifying the reclassification.
This regulation establishes tolerances for residues of pyroxasulfone in or on the nut, tree, group 14-12; the fruit, small, vine climbing, except fuzzy kiwifruit, subgroup 13-07F; and almond hulls. K-I Chemical U.S.A., Inc. requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).
EPA is issuing significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for certain chemical substances that were the subject of premanufacture notices (PMNs) and a Microbial Commercial Activity Notice (MCAN) and are also subject to an Order issued by EPA pursuant to TSCA. The SNURs require persons to notify EPA at least 90 days before commencing the manufacture (defined by statute to include import) or processing of any of these chemical substances for an activity that is designated as a significant new use in the SNUR. The required notification initiates EPA's evaluation of the conditions of that use for that chemical substance. In addition, the manufacture or processing for the significant new use may not commence until EPA has conducted a review of the required notification; made an appropriate determination regarding that notification; and taken such actions as required by that determination.
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the Rhode Island Department of Environmental Management Office of Air Resources on December 20, 2023, that includes an amended regulation for the Enhanced Motor Vehicle Inspection and Maintenance (I/M) program in Rhode Island. Overall, the submittal removes obsolete references, adds definitions, and clarifies the Rhode Island I/M program requirements, which consist primarily of conducting Onboard Diagnostics (OBD) testing. The intended effect of this action is to propose approval of the State's amended I/M program regulation into the Rhode Island SIP. This action is being taken under the Clean Air Act (CAA). EPA has evaluated the SIP revision and has preliminarily determined the changes will not impact emissions under the Rhode Island I/M program. EPA is proposing to conclude that approval of the SIP revision will not interfere with attainment or maintenance of any National Ambient Air Quality Standard (NAAQS) or with any other applicable requirement of the CAA. Therefore, EPA is proposing to determine that Rhode Island's December 20, 2023, SIP revision is consistent with the applicable provisions of the CAA.
The Environmental Protection Agency (EPA) is proposing to approve the regional haze State Implementation Plan (SIP) revision submitted by Washington on January 28, 2022, to address applicable requirements under the Clean Air Act (CAA) and the EPA's Regional Haze Rule (RHR) for the regional haze program's second implementation period. The EPA is proposing this action pursuant to the CAA.
The Environmental Protection Agency (EPA) is proposing to approve a state implementation plan (SIP) revision and redesignation request submitted on August 12, 2024 by the Pennsylvania Department of Environmental Protection (PADEP).

The Environmental Protection Agency (EPA) is proposing to approve a revision to the State of New York's State Implementation Plan (SIP) for the ozone National Ambient Air Quality Standard (NAAQS) related to a source-specific SIP (SSSIP) revision for Ortho Clinical Diagnostics, 513 Technology Boulevard, Rochester, New York (the Facility). The EPA is proposing to find that the control options in this SSSIP revision implement Reasonably Available Control Technology (RACT) with respect to volatile organic compound (VOC) emissions from the relevant Facility source, which are identified as one solvent-based film coating machine. This SSSIP revision is intended to implement VOC RACT for the relevant Facility source in accordance with the requirements for implementation of the 2008 and 2015 ozone NAAQS. EPA proposes to determine that this action will not interfere with ozone NAAQS requirements and meets all applicable requirements of the Clean Air Act (CAA).
Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to approve revisions to the Texas State Implementation Plan (SIP). The revisions were submitted by the Texas Commission on Environmental Quality (TCEQ) on May 12, 2020, and May 13, 2020, and address certain CAA requirements for the Dallas-Fort Worth (DFW) Serious Nonattainment Area (NAA) for the 2008 ozone National Ambient Air Quality Standard (NAAQS). Specifically, EPA is proposing to approve the revisions to 30 Texas Administrative Code (TAC) Chapter 117 to implement the major source Reasonably Available Control Technology (RACT) requirement for Nitrogen Oxides (NO<INF>X</INF>), as addressed in the NO<INF>X</INF> RACT analysis and negative declaration included with the Serious area Attainment Demonstration (AD) SIP revision. The volatile organic compounds (VOC) portion of the RACT analysis in the Serious area AD submittal is addressed in a separate action.
The Environmental Protection Agency (EPA) is proposing conditional approval of five permitting rules as a revision to the Mojave Desert Air Quality Management District (MDAQMD) portion of the California State Implementation Plan (SIP). These are revisions to the District's New Source Review (NSR) air permitting program rules for new and modified sources of air pollution under the Clean Air Act (CAA or "Act"). The submitted rules address deficiencies identified in a previous limited disapproval action and incorporate other revisions related to the NSR permitting requirements. If finalized, this action will update the MDAQMD's current SIP with the revised rules. As a separate action in this Federal Register, we are making an interim final determination that will stay or defer the imposition of CAA sanctions associated with our previous limited disapproval action.
The Environmental Protection Agency (EPA) is making an interim final determination that the California Air Resources Board (CARB) has submitted a Clean Air Act (CAA or "Act") state implementation plan (SIP) revision on behalf of the Mojave Desert Air Quality Management District (MDAQMD or "District") that corrects deficiencies concerning the District's New Source Review (NSR) stationary source permitting program. This determination is based on a proposed conditional approval, published elsewhere in this issue of the Federal Register, of MDAQMD Rules. The effect of this interim final determination is to stay the application of the offset sanction and to defer or stay the action of the highway sanction that were triggered by the EPA's limited disapproval of MDAQMD Rules on June 30, 2023.
The Environmental Protection Agency (EPA) is supplementing a proposed rule published on March 10, 2021, to approve revisions to the Texas State Implementation Plan (SIP) concerning Nitrogen Oxide (NO<INF>X</INF>) and Volatile Organic Compound (VOC) Reasonably Available Control Technology (RACT) requirements for the Serious Houston-Galveston-Brazoria (HGB), 2008 8-hour ozone National Air Quality Ambient Air Quality Standard (NAAQS) nonattainment area. Because of comments received on the March 10, 2021, proposal, we are providing additional analysis, in this proposal, regarding the RACT requirements which apply to sources of VOC in this area. Consistent with this analysis, EPA is proposing to determine that the Texas Rules meet the RACT requirements for sources of VOCs in the HGB Serious ozone nonattainment area for the purposes of the 2008 standard. The NO<INF>X</INF> portion of the RACT analysis in the March 10, 2021, proposal will be addressed in a separate action. The EPA is providing an opportunity for public comment on this supplemental proposal. Comments received on the March 10, 2021, proposal and this supplemental proposal will be addressed in a final rule.
The Environmental Protection Agency (EPA) is approving the Commonwealth of Pennsylvania's request to redesignate to attainment the Liberty-Clairton, Pennsylvania nonattainment area (Liberty-Clairton Area) for the 1997 annual and 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS or standard).
