The Environmental Protection Agency (EPA) is proposing to approve Louisiana's State Implementation Plan (SIP) revision submitted to EPA on April 2, 2025, for the Evangeline Parish 2010 1-hour sulfur dioxide (SO<INF>2</INF>) primary national ambient air quality standard (NAAQS) nonattainment area. EPA is proposing approval of the following Clean Air Act (CAA) SIP elements: The attainment demonstration for the SO<INF>2</INF> NAAQS, which includes an Agreed Order on Consent (AOC) for the Cabot Corporation's Ville Platte Plant (Cabot) facility; the reasonable further progress (RFP) plan; the reasonably available control measures (RACM) and reasonably available control technology (RACT) demonstration; the emission inventories; and the contingency measures. The State has demonstrated that its current Nonattainment New Source Review (NNSR) program covers this NAAQS; therefore, no revision to the SIP is required for the NNSR element.
The Environmental Protection Agency (EPA) is proposing to approve revisions to the Missouri State Implementation Plan (SIP) related to the control of emissions during petroleum liquid storage, loading and transfer in the Kansas City metropolitan area. The revisions to this rule include adding incorporations by reference to other state rules, adding definitions specific to the rule, revising unnecessarily restrictive or duplicative language, and making administrative wording changes. 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).
In the Proposed Rules section of this Federal Register, EPA is proposing approval of portions of State Implementation Plan (SIP) submissions from the State of Colorado dated June 26, 2023, May 23, 2024, and April 2, 2025. The submissions relate to Colorado Air Quality Control Commission Regulation Number 7 (Reg. 7) and Regulation Number 25 (Reg. 25) and address Colorado's SIP obligations for the contingency measures Serious ozone nonattainment area requirement for the 2008 ozone National Ambient Air Quality Standard (NAAQS). In this action, the EPA is making an interim final determination based on that proposed approval. The effect of this interim final determination is that the imposition of sanctions that were triggered by the EPA's November 7, 2023 disapproval are now deferred. Although this action is effective upon publication, the EPA will take comment on this interim final determination.
The Environmental Protection Agency (EPA) is proposing to approve state implementation plan (SIP) submittals under the Clean Air Act (CAA) that address contingency measures requirements for the 2008 ozone National Ambient Air Quality Standards (NAAQS) for the Denver Metro/North Front Range (DMNFR) ozone nonattainment area. The requirements at issue relate to the area's previous Serious nonattainment classification. The EPA is proposing to find that the State has met the applicable CAA requirements for Serious area contingency measures and is proposing approval of the contingency measures SIP submittals, except that we are not taking action on one of the two identified contingency measures included in the submittals. In addition, the EPA is proposing to approve regulatory revisions that Colorado adopted to implement the submitted motor vehicle coating contingency measure. The EPA is taking this action pursuant to the CAA.
The Environmental Protection Agency (EPA) is approving revisions to the Ohio State Implementation Plan (SIP) submitted by the Ohio Environmental Protection Agency (Ohio EPA) on November 4, 2024.

The revised rules include non-substantive updates to rule language and updates to referenced material.
The Environmental Protection Agency (EPA) is proposing to approve revisions to the Ohio State Implementation Plan (SIP) submitted by the Ohio Environmental Protection Agency (Ohio EPA) on November 4, 2024. The SIP revisions consist of revised Ohio Administrative Code (OAC) rules implementing the Nitrogen Oxide (NO<INF>X</INF>) Budget Program. The revised rules include non- substantive updates to rule language and updates to referenced material.
The Environmental Protection Agency (EPA) is proposing approval of a State Implementation Plan (SIP) revision submitted by the Missouri Department of Natural Resources (MoDNR) on November 14, 2018. MoDNR requests that the EPA remove from its SIP two rules related to control of emissions of nitrogen oxides (NO<INF>X</INF>). One of the rules previously applied to electricity generating units (EGUs) and certain non-EGUs in a portion of the state and the other rule previously applied to EGUs throughout the entire state. The EPA has already approved a SIP revision that included provisions to sunset the two rules, and removal of the now-sunsetted rules from the SIP would not 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 taking final action to approve revisions to the State Implementation Plan (SIP) and Operating Permits Program and the 112(l) plan submitted by the State of Kansas on February 20, 2023. The revised Kansas rules update the Class I emission fee and emissions inventory regulations, establish a Class II fee schedule and ensure that Kansas's Operating Permits Program is adequately funded. Approval of these revisions ensures consistency between the State and federally-approved rules and does not impact air quality.
The Environmental Protection Agency (EPA) is approving both a redesignation request and state implementation plan (SIP) revision submitted on November 14, 2023 by the Commonwealth of Pennsylvania on behalf of the Allegheny County Health Department (ACHD). The request asked the EPA to redesignate the Allegheny County, Pennsylvania area from nonattainment to attainment for the 2010 1-hour primary sulfur dioxide (SO<INF>2</INF>) national ambient air quality standard (NAAQS), while the revision included Allegheny County's maintenance plan for the 2010 1-hour primary SO<INF>2</INF> standard for the Allegheny County Area. The EPA is approving this redesignation of the Allegheny County Area from nonattainment to attainment for the 2010 SO<INF>2</INF> NAAQS and the revision to the Pennsylvania SIP in accordance with the requirements of the Clean Air Act (CAA).
The Environmental Protection Agency (EPA) is proposing to modify nitrogen oxide (NO<INF>X</INF>) emission limits for the indurating furnace at United States Steel's (U.S. Steel's) Keetac taconite facility in Keewatin, Minnesota (Keetac), to satisfy the requirement for best available retrofit technology (BART) at taconite facilities. EPA is proposing this action pursuant to sections 110 and 169A of the Clean Air Act (CAA).
The Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) revisions submitted by the State of Connecticut for the 2015 ozone National Ambient Air Quality Standard (NAAQS). These revisions certify the adequacy of the SIP to satisfy the nonattainment new source review permitting requirements of the Clean Air Act (CAA) for the reclassification of the Greater Connecticut area to moderate nonattainment for the 2015 ozone NAAQS, and certify the emission statement program satisfies CAA requirements for the initial nonattainment designations and the reclassification to moderate nonattainment for the 2015 ozone NAAQS. This action is being taken in accordance with the CAA.
The Environmental Protection Agency (EPA) is revising the format for materials that are made part of the Wisconsin State Implementation Plan (SIP) through the process of incorporation by reference (IBR). The regulations and materials affected by this format change have all been previously submitted by Wisconsin and approved by EPA as part of the SIP.
The Environmental Protection Agency (EPA) is closing the reopened comment period on the proposed Standards of Performance for New Stationary Sources and Emission Guidelines for Existing Sources: Large Municipal Waste Combustors Voluntary Remand Response and 5-Year Review. The original proposed rule was published on January 23, 2024, with a 60-day comment period closing March 25, 2024. This comment period was reopened on January 16, 2025, for an additional 6 months. The EPA is providing notice that the comment period for this rule will now close on May 30, 2025. We believe that a 6.5-month comment period in total is sufficient for interested stakeholders to submit comments and additional data.
The Environmental Protection Agency (EPA) is proposing to approve under the Clean Air Act (CAA) a request from the Indiana Department of Environmental Management (IDEM) to revise the Indiana State Implementation Plan (SIP) to incorporate revisions to nitrogen oxides (NO<INF>X</INF>) emissions monitoring, reporting and record keeping requirements for new and existing large non-Electric Generating Units (non-EGUs) affected by the NO<INF>X</INF> SIP Call. This SIP revision would approve monitoring, reporting, and record keeping requirements that are permissible as alternatives under Federal rules for these sources for purposes of the NO<INF>X</INF> SIP Call.
The Environmental Protection Agency (EPA) is proposing to approve the regional haze State implementation plan (SIP) revision submitted by West Virginia (West Virginia, WV, or the State) on August 12, 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 EPA is also withdrawing its previous proposed rule to disapprove West Virginia's regional haze SIP revision as published in the Federal Register on January 21, 2025.
The Environmental Protection Agency (EPA) is approving a September 28, 2023, State Implementation Plan (SIP) submittal from the Ohio Environmental Protection Agency (Ohio EPA). The SIP submittal consists of a source-specific volatile organic compound (VOC) limitation for a flexographic printing line cold cleaner at the Valgroup company's plastic extrusion plant in Findlay, Ohio. The source-specific limitation reflects the technological differences between the facility's new control unit and cold cleaner requirements currently established in Ohio's SIP. Ohio EPA has determined that the source-specific VOC limitation for the cold cleaner is more stringent than existing cold cleaner limits in the Ohio SIP. EPA proposed to approve this action on October 7, 2024, and received no adverse comments.
The Environmental Protection Agency (EPA) is approving revisions to the Washington State Implementation Plan (SIP) that were submitted by the Department of Ecology (Ecology) in coordination with the Spokane Regional Clean Air Agency (SRCAA). In 2021, the EPA approved a comprehensive update to the SRCAA general air quality regulations in the SIP, which include new source review permitting requirements as well as other general requirements for sources regulated under SRCAA's jurisdiction. In this action, the EPA is approving additional updates to the SRCAA general air quality regulations promulgated since our comprehensive approval in 2021.
The Environmental Protection Agency (EPA) is finalizing, largely as proposed, a narrow modification to its 2022 Construction General Permit (CGP) to expand the list of areas eligible for coverage to include construction projects in all Lands of Exclusive Federal Jurisdiction. This modification is necessary because the EPA is the permitting authority in Lands of Exclusive Federal Jurisdiction, and when the CGP was issued on February 17, 2022, the permit did not specifically provide eligibility for these areas as a class. The modification also clarifies the CGP requirements that apply to projects that discharge to receiving waters within Lands of Exclusive Federal Jurisdiction in response to the Supreme Court's recent decision in City and County of San Francisco v. EPA. The permit modification and accompanying permit fact sheet can be found at https://www.epa.gov/ npdes/2022-construction-general-permit-cgp.
Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to approve the portion of the State Implementation Plan (SIP) submittal from the State of Louisiana demonstrating that the State satisfies the interstate transport requirements of section 110(a)(2)(D)(i)(I), also known as the "good neighbor" provision of the CAA, for the 2010 1-hour sulfur dioxide (SO<INF>2</INF>) primary National Ambient Air Quality Standard (NAAQS). The good neighbor provision requires each State's implementation plan contain adequate provisions prohibiting the interstate transport of air pollution in amounts that will contribute significantly to nonattainment, or interfere with maintenance, of a NAAQS in any other State.
Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving revisions to the Texas State Implementation Plan (SIP) submitted to the EPA by the Texas Commission on Environmental Quality (TCEQ or State) on December 18, 2023. The SIP revisions address Control of Air Pollution from Motor Vehicles and establish a Motor Vehicle Inspection and Maintenance (I/M) program for the San Antonio ozone nonattainment area. The revisions also update definitions and address options for displaying a vehicle's registration as proof of compliance with I/M requirements. Additionally, this final action terminates the EPA's requirement to promulgate a Federal Implementation Plan (FIP) for a Basic I/M program in the San Antonio nonattainment area.
This document announces the Agency's receipt of initial filings of pesticide petitions requesting the establishment or modification of regulations for residues of pesticide chemicals in or on various commodities. EPA is hereby providing notice of receipt and opportunity to comment on these petitions.
The Environmental Protection Agency (EPA) is proposing to approve a request from the Commonwealth of Pennsylvania to redesignate the Liberty-Clairton, Pennsylvania nonattainment area (Liberty-Clairton Area) to attainment for the 1997 annual and 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS or standard). The EPA is also proposing to approve, as revisions to the Pennsylvania state implementation plan (SIP), the Commonwealth's plan for maintaining the 1997 annual and 2006 24-hour PM<INF>2.5</INF> NAAQS through 2035 for the Liberty-Clairton Area. Additionally, the EPA is proposing to approve the maintenance plan for the Allegheny County, Pennsylvania nonattainment area (Allegheny County Area) for the 2012 annual PM<INF>2.5</INF> NAAQS through 2035. The maintenance plan includes 2017, 2026, and 2035 mobile vehicle emissions budgets (MVEBs) for mobile sources of PM<INF>2.5</INF> and nitrogen oxides (NO<INF>X</INF>) for the Allegheny County Area. The EPA is proposing to find these 2017, 2026, and 2035 MVEBs for PM<INF>2.5</INF> and NO<INF>X</INF> adequate and to approve these MVEBs into the Pennsylvania SIP for transportation conformity purposes. This action does not redesignate the Allegheny County Area to attainment for the 2012 annual PM<INF>2.5</INF> NAAQS, as Pennsylvania withdrew its redesignation request specific to the Allegheny County Area. The redesignation request and maintenance plan were submitted by the Commonwealth of Pennsylvania Department of Environmental Protection (PADEP or Pennsylvania) on behalf of the Allegheny County Health Department (ACHD). This action is being taken under the CAA.
This regulation establishes tolerances for residues of tiafenacil in or on multiple commodities. ISK Biosciences Corporation requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).
The Environmental Protection Agency (EPA) is proposing approval of State Implementation Plan (SIP) revisions submitted by the State of Connecticut that relate to the 2015 Ozone National Ambient Air Quality Standards (NAAQS). The SIP revisions are for the Greater Connecticut and the Connecticut portion of the New York-Northern New Jersey-Long Island, NY-NJ-CT ozone nonattainment areas. The intended effect of this action is to propose approval of submittals which include a 2017 base year emissions inventory for the 2015 Ozone National Ambient Air Quality Standard. This action is being taken under the Clean Air Act.
This regulation establishes an exemption from the requirement of a tolerance for residues of choline chloride (CASRN 67-48-1) when used as an inert ingredient (adjuvant) applied to or on animals. Stratacor, Inc. on behalf of Emery Olochemicals LLC, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA), requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of choline chloride, when used in accordance with the terms of the exemption.
The Environmental Protection Agency (EPA) is finalizing multiple actions related to the Washington, DC-MD-VA nonattainment area (the Washington Area or the Area) for the 2015 8-hour ozone national ambient air quality standards (2015 ozone NAAQS). First, the EPA is determining that the Washington Area attained the 2015 ozone NAAQS by the applicable attainment date of August 3, 2024. Second, the EPA is determining that the Washington Area has clean data under the EPA's Clean Data Policy. Lastly, the EPA is taking final action on an exceptional events request submitted by the District of Columbia (DC) on March 20, 2024, and concurred on by the EPA on July 17, 2024. This action addresses the EPA's obligation under Clean Air Act (CAA) sections 179(c) and 181(b)(2) to determine whether the Washington Area attained the 2015 ozone NAAQS by the August 3, 2024 attainment date and, as set forth in the EPA's Clean Data Policy, will suspend the obligation of DC, the State of Maryland (MD), and the Commonwealth of Virginia (VA) to submit certain attainment planning requirements for as long as the Washington Area continues to attain the 2015 ozone NAAQS. This action is being taken under the CAA.
EPA is proposing 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 are also subject to an Order issued by EPA pursuant to TSCA. The SNURs require persons who intend to manufacture (defined by statute to include import) or process any of these chemical substances for an activity that is proposed as a significant new use by this rulemaking to notify EPA at least 90 days before commencing that activity. 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 approving 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 Lehigh Cement Company LLC, located at 313 Warren Street, Glens Falls, New York (the Facility). The control options in this SSSIP revision implement Reasonably Available Control Technology (RACT) with respect to nitrogen oxide (NO<INF>X</INF>) emissions from the relevant Facility source, which is identified as one Portland cement kiln (the Kiln). This action is being taken in accordance with the requirements of the Clean Air Act (CAA) for implementation of the 2008 and 2015 ozone NAAQS. The EPA proposed to approve this rule on December 26, 2024, and received no comments. This final action will not interfere with ozone NAAQS requirements and meets all applicable requirements of the CAA.
The Environmental Protection Agency (EPA or Agency) is postponing the effectiveness of certain regulatory provisions of the final rule entitled "Trichloroethylene (TCE); Regulation Under the Toxic Substances Control Act (TSCA)" for 90 days pending judicial review. Specifically, this postponement applies to the conditions imposed on the uses with TSCA exemptions.
The Environmental Protection Agency (EPA) is proposing to approve a revision to the Placer County Air Pollution Control District (PCAPCD or "District") portion of the California State Implementation Plan (SIP). This revision concerns the District's Clean Air Act (CAA or "Act") nonattainment new source review permitting program that regulates construction and modifications of major stationary sources of air pollution in nonattainment areas. We are proposing to approve a local rule that has been revised to address deficiencies previously identified by the EPA in a prior action that included a limited approval/limited disapproval of a prior version of the rule. We are taking comments on this proposal and plan to follow with a final action. Elsewhere in this Federal Register, we are making an interim final determination that will defer the imposition of CAA sanctions associated with our previous limited disapproval.
