The Environmental Protection Agency (EPA) is approving certain portions of State Implementation Plan (SIP) revisions submitted by the State of North Dakota (North Dakota) on January 12, 2015, and August 11, 2022, to address regional haze. Specifically, the EPA is approving North Dakota's nitrogen oxides (NO<INF>X</INF>) Best Available Retrofit Technology (BART) determination for Coal Creek Station power plant (Coal Creek) for the first implementation period of the regional haze program and North Dakota's five-year regional haze progress report. This action addresses the United States Court of Appeals for the Eighth Circuit's September 23, 2013, vacatur and remand of the portion of EPA's 2012 Regional Haze Federal Implementation Plan (FIP) that promulgated a BART emission limit of 0.13 pounds per million BTU (lb/ MMBtu) NO<INF>X</INF> (30-day rolling average) for Coal Creek. The EPA is taking this action pursuant to the Clean Air Act (CAA).
The U.S. Environmental Protection Agency (EPA) is finalizing new source performance standards (NSPS) and emission guidelines (EG) for the large municipal waste combustion (MWC) source category. This final rule responds to a voluntary remand of the preceding rule for this source category and announces the results of the non-discretionary review at five-year intervals required by Clean Air Act (CAA) section 129(a)(5), fulfilling the requirements of a consent decree for the source category. The final rule revises the remanded emission limits for cadmium, lead, particulate matter, polychlorinated dibenzodioxins and dibenzofurans, mercury, hydrogen chloride, and sulfur dioxide for all sources subject to the NSPS and EG and the remanded emission limits for nitrogen oxides and carbon monoxide for some sources subject to the EG and all sources subject to the NSPS. This final rule also removes certain startup, shutdown, and malfunction (SSM) exclusions and exemptions. In addition, the EPA is taking this opportunity to streamline regulatory language; revise recordkeeping and reporting requirements; establish electronic notification; reestablish new and existing source applicability dates; eliminate title V requirements for air curtain incinerators that burn only wood waste, yard waste, and clean lumber; close a 2007 proposed reconsideration action; and make certain typographical and technical corrections and clarifications. The EPA estimates this final rule will result in 3,269 tpy reduction in regulated pollutants from existing sources through implementation of the final emission limits.
The Environmental Protection Agency (EPA) is proposing to delay the compliance date for Facility Response Plan (FRP) requirements as well as to make language modifications to align with the Administration's climate change and environmental justice policies in Executive Order 14148 of January 20, 2025. These requirements are for onshore non-transportation-related facilities that could reasonably be expected to cause substantial harm to the environment from a CWA hazardous substance worst case discharge to navigable waters, adjoining shorelines, or the exclusive economic zone. This delay action is necessary to allow the Agency to consider implementation and compliance assistance tools that regulated parties may be able to take advantage of when complying with the new requirements. EPA notes that it cannot quantify the number, nature, and magnitude of covered discharges that may occur during the proposed rule delay period.
The U.S. Environmental Protection Agency (EPA) is proposing regulatory amendments to the hazardous waste manifest regulations to establish a date for sunsetting use of paper manifests in favor of electronic manifests. Phasing out paper manifests would unlock the estimated $28.5 million annual savings through decreased burden to manifest users while also increasing human health and environmental protection through better tracking of hazardous waste and greater transparency for regulators and the public. The proposed rule also introduces several conforming amendments to existing regulations. These include new registration requirements with the EPA's e-Manifest system for RCRA hazardous waste transporters, certain PCB waste generators, and PCB waste transporters. Additionally, the rule updates exception reporting requirements for very small quantity generators (VSQGs) managing hazardous waste from episodic events, as well as for healthcare facilities and reverse distributors handling hazardous waste pharmaceuticals. It also revises discrepancy reporting requirements for owners and operators of hazardous waste facilities operating under standardized permits. Lastly, the proposed rule includes four technical corrections to the import and export requirements to correct EPA's mailing address, remove obsolete text, and correct a citation associated with manifest corrections for export shipments.
Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to approve the CAA section 111(d) state plan submitted by the State of Texas for sources subject to the Municipal Solid Waste (MSW) Landfills Emission Guidelines (EG). The Texas MSW landfills plan was submitted to fulfill the state's obligations under CAA section 111(d) to implement and enforce the requirements under the MSW Landfills EG. The EPA is proposing to approve the state plan and amend the agency regulations in accordance with the requirements of the CAA.
The U.S. Environmental Protection Agency (EPA) is proposing amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the marine tank vessel loading operations (MTVLO) source category under Clean Air Act (CAA) section 112. The EPA is proposing certain decisions resulting from the Agency's technology review of the MTVLO NESHAP pursuant to CAA section 112(d)(6). Specifically, the EPA is proposing enhanced flare monitoring requirements, requirements to perform periodic performance testing, electronic reporting provisions, and removal of startup, shutdown, and malfunction (SSM) exemptions.
The Environmental Protection Agency (EPA) proposes to approve an August 20, 2024 request by the Oregon Department of Environmental Quality (Oregon) to revise the attainment plan for the Klamath Falls, Oregon, nonattainment area; redesignate the Klamath Falls nonattainment area to attainment for the 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) National Ambient Air Quality Standard (NAAQS); and approve into the Oregon state implementation plan (SIP) a maintenance plan for the area that demonstrates continued attainment through 2037. This proposed rulemaking includes approving the motor vehicle emission budget for the area and approving updated state rules and the Klamath County Clean Air Ordinance, to be incorporated by reference. EPA proposes these actions pursuant to the Clean Air Act (CAA or the Act).
The Environmental Protection Agency (EPA) is issuing a Notice of Intent to delete six sites and partially delete two sites from the National Priorities List (NPL) and requests public comments on this proposed action. The NPL, promulgated pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). The EPA and the applicable states, through their designated state agency, have determined that all appropriate response actions under CERCLA have been completed. However, this deletion does not preclude future actions under Superfund.
The Environmental Protection Agency (EPA) announces the deletion of one site, Corozal Well, from the Superfund National Priorities List (NPL). The NPL, created under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980, as amended, is an appendix of the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). In accordance with 40 CFR 300.425(e), sites may be deleted from the NPL where no further response is appropriate. The EPA and the Commonwealth of Puerto Rico, through the Puerto Rico Department of Natural and Environmental Resources (PRDNER), have determined that all appropriate response actions under CERCLA have been completed and no further response is appropriate. However, this deletion does not preclude future actions under Superfund.
The Environmental Protection Agency (EPA) is proposing to approve revisions to the Arizona state implementation plan (SIP) for attaining the 1971 and 2010 sulfur dioxide (SO<INF>2</INF>) national ambient air quality standards (NAAQS or "standards") in the Hayden SO<INF>2</INF> nonattainment area. These SIP revisions, collectively referred to as the "Hayden SO<INF>2</INF> Plan" or "Plan," include Arizona's attainment demonstration and other elements required under Clean Air Act (CAA or "Act") sections 110, 172, 191, and 192. In addition to an attainment demonstration, the revisions address the requirements for meeting reasonable further progress (RFP) toward attainment of the NAAQS, reasonably available control measures and reasonably available control technology (RACM/RACT), base-year and projection-year emissions inventories, nonattainment new source review (NSR), emissions limitations necessary to provide for attainment, and contingency measures. The EPA is proposing to approve the SIP revisions as meeting the CAA requirements. This action is being taken under the CAA. We are taking comments on this proposal and plan to follow with a final action.
The Environmental Protection Agency (EPA) is extending the comment period for the proposed "Interstate Transport Plan Review for the 2015 Ozone NAAQS," published in the Federal Register on January 30, 2026. The current comment period for the proposed rule is set to end on March 2, 2026. The EPA has received numerous requests to extend the comment period. The EPA is extending the comment period for the proposed action to March 23, 2026.
The Environmental Protection Agency (EPA) is approving the Alaska regional haze plan for the second implementation period. Alaska submitted the plan to address applicable requirements under the Clean Air Act and the EPA's Regional Haze Rule.
The U.S. Environmental Protection Agency (EPA) is announcing the approval of the petition by the Commonwealth of Kentucky ("Kentucky" or "the Commonwealth") to opt out of the reformulated gasoline (RFG) program and remove the requirement to sell RFG in Jefferson County and parts of Bullitt and Oldham Counties (the "Kentucky portion of the Louisville Area"), which are part of the Louisville Moderate nonattainment area for the 2015 ozone National Ambient Air Quality Standard (NAAQS) and the maintenance area for the 1997 ozone NAAQS. Specifically, by letter dated February 26, 2026, to the Governor of Kentucky, the EPA has approved the Commonwealth's petition and set an effective date for the opt-out from the RFG program as May 27, 2026. The EPA has determined that this removal of the RFG program for the Kentucky portion of the Louisville Area is consistent with the applicable provisions of the Clean Air Act (CAA) and the EPA's regulations.
The Environmental Protection Agency (EPA or the Agency) is updating the list of chemicals subject to toxic chemical release reporting under the Emergency Planning and Community Right-to-Know Act (EPCRA) and the Pollution Prevention Act (PPA). Specifically, this action updates the regulations to identify one perfluoroalkyl substance that must be reported pursuant to the National Defense Authorization Act for Fiscal Year 2020 (FY 2020 NDAA) enacted on December 20, 2019. As this action is being taken to conform the regulations to a Congressional legislative mandate, notice and comment rulemaking is unnecessary.
The U.S. Environmental Protection Agency (EPA) is promulgating this final rule to extend the reporting deadline under the Greenhouse Gas Reporting Rule for reporting year 2025 from March 31, 2026 to October 30, 2026. This final rule changes only the reporting deadline for annual greenhouse gas (GHG) reports for reporting year 2025 in response to comments received on the proposed rescission of the Greenhouse Gas Reporting Program (GHGRP). The EPA anticipates addressing the remainder of the proposed rule in one or more subsequent final actions.
This regulation revises a use of pyridate on mint (with tolerances on mint, fresh leaves and mint, dried leaves); a crop group expansion to field corn subgroup 15-22C; and a crop group conversion to vegetable, brassica, head and stem, group 5-16, which includes a tolerance on orphan crop kohlrabi. The Interregional Project Number 4 (IR-4) requested this tolerance under the Federal Food, Drug, and Cosmetic Act (FFDCA).
The Environmental Protection Agency (EPA) is proposing to approve the regional haze State Implementation Plan (SIP) revision submitted by the Illinois Environmental Protection Agency (Illinois EPA) on June 3, 2024, as satisfying applicable requirements under the Clean Air Act (CAA) and the EPA's Regional Haze Rule for the program's second implementation period. The EPA proposes to find that Illinois' regional haze SIP submission fulfills 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 in mandatory Class I Federal areas. The EPA is also proposing to approve portions of Illinois' September 29, 2017, and May 16, 2019, infrastructure SIP submissions for the 2012 fine particulate matter (PM<INF>2.5</INF>) and 2015 ozone National Ambient Air Quality Standards (NAAQS), respectively. The EPA is proposing that Illinois' infrastructure submissions fulfill CAA requirements for a State's SIP to contain adequate provisions prohibiting emissions that will interfere with required visibility protection measures in any other State's SIP.
The Environmental Protection Agency (EPA) is proposing to approve revisions and additions to Michigan Air Pollution Control Rules (MAPCR) Parts 6 and 8 for inclusion in the Michigan State Implementation Plan (SIP). Michigan submitted these SIP revisions to meet the Moderate Volatile Organic Compound (VOC) and Nitrogen Oxide (NO<INF>X</INF>) Reasonably Available Control Technology (RACT) requirements for the Western Michigan nonattainment areas (Berrien, Western portion of Allegan, and Western portion of Muskegon counties) under the 2015 ozone National Ambient Air Quality Standard (NAAQS or standard). The EPA is also proposing to approve MAPCR Rules that limit VOC emissions from consumer products and architectural and industrial maintenance coatings, as SIP strengthening measures for the Western Michigan nonattainment areas under the 2015 ozone standard. The Michigan Department of Environment, Great Lakes, and Energy (Michigan or EGLE) submitted the VOC SIP revisions on March 7, 2024, supplementing the submittal on May 2, 2024, and submitted the NO<INF>X</INF> SIP revisions on May 5, 2025, supplementing the submittal on August 6, 2025.
The Environmental Protection Agency (EPA or Agency) is finalizing several pesticide tolerance actions under the Federal Food, Drug, and Cosmetic Act (FFDCA) that the Agency previously determined were necessary or appropriate during the registration review conducted under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). During registration review, EPA reviews all aspects of a pesticide case, including existing tolerances, to ensure that the pesticide continues to meet the standard for registration under FIFRA. The Agency is also finalizing tolerance actions identified outside of registration review as housekeeping measures, such as removing expired tolerances from the Code of Federal Register (CFR). The pesticide tolerances and active ingredients addressed in this rulemaking are identified and discussed in detail in Unit III. of this document.
The Environmental Protection Agency (EPA) is proposing to approve revisions to the volatile organic compound (VOC) requirements for Keystone Automotive Industries dba Saturn Wheel (Keystone) of Huntington County, Indiana. Keystone owns and operates an aluminum alloy wheel refurbishing and distribution facility at which it performs cold cleaner degreasing operations and is subject to the VOC rules under article 8 of the Indiana Administrative Code (IAC). On February 26, 2025, the Indiana Department of Environmental Management (IDEM) submitted a Commissioner's Order containing the revised requirements and requested that the EPA approve it as an amendment to the Indiana State Implementation Plan (SIP). IDEM is seeking the EPA approval of an equivalent control device and site specific Reasonably Available Control Technology (RACT) for Keystone's degreasing operations, as provided in IAC article 8.
The Environmental Protection Agency (EPA) is proposing to approve source-specific State Implementation Plan (SIP) revisions submitted by Ohio. These revisions address major source volatile organic compound (VOC) and nitrogen oxide (NO<INF>X</INF>) reasonably available control technology (RACT) requirements for the Cleveland, OH Moderate nonattainment area under the 2015 ozone National Ambient Air Quality Standard (NAAQS or standard). The affected facilities include PPG Industries Ohio, Inc. (PPG), Owens Corning, Akron Paint and Varnish, Charter Steel, U.S. Steel Tubular Lorain, Carmeuse Lime, and Ross Incineration. The EPA is also proposing to approve source-specific SIP revisions for General Electric Aviation Evendale and Tyson Foods for the Cincinnati maintenance area under the 2015 ozone standard. Finally, the EPA is proposing to rescind the source-specific VOC RACT rule for Formica Corporation since it is subject to an equivalent CTG-based rule in the Ohio Administrative Code (OAC).
The Environmental Protection Agency (EPA) is proposing to determine under the Clean Air Act (CAA) that the Cleveland, Ohio nonattainment area (hereafter also referred to as "Cleveland area" or "area") has attained the 2015 ozone National Ambient Air Quality Standard (NAAQS or standard). This determination is based upon complete, quality-assured, and certified ambient air monitoring data for the 2023-2025 design period showing that the Cleveland area achieved attainment of the 2015 ozone NAAQS. This determination relies on an exceptional events request submitted by the Ohio Environmental Protection Agency (Ohio EPA) on December 8, 2025, which the EPA concurred with on January 12, 2026. The EPA is proposing to take final agency action on Ohio's exceptional events request and the EPA's concurrence. As a result of this determination, the EPA is proposing to suspend the requirements for the state to submit an attainment demonstration and associated Reasonable Available Control Measures (RACM), Reasonable Further Progress (RFP) plans, contingency measures for failure to attain or make reasonable progress, and other planning State Implementation Plans (SIPs) related to attainment of the 2015 NAAQS, for as long as the Cleveland area continues to attain the 2015 ozone NAAQS.
The Environmental Protection Agency (EPA or the Agency) is approving the Wyoming partial 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 determined that Wyoming's partial CCR permit program meets the standard for approval under RCRA. Wyoming's partial CCR permit program will operate in lieu of the Federal CCR program, with the exception of the specific provisions noted below.
The Environmental Protection Agency (EPA) is proposing to determine under the Clean Air Act (CAA) that the Illinois portion of the St. Louis, MO-IL nonattainment area (hereafter also referred to, respectively, as the "St. Louis area" or "area") has attained the 2015 ozone National Ambient Air Quality Standards (NAAQS or standard). This determination is based upon complete, quality-assured, and certified ambient air monitoring data for the 2023-2025 design value period showing that the Illinois portion of the area achieved attainment of the 2015 ozone NAAQS. This determination also relies on the EPA concurrence of an exceptional events request submitted by the Illinois Environmental Protection Agency (Illinois EPA) on December 18, 2025, and concurred on by the EPA on January 12, 2026. Therefore, the EPA is proposing to take final agency action on Illinois' exceptional events request. In a separate action, the EPA is proposing a similar determination for the Missouri portion of the St. Louis area. If finalized, this determination would suspend the requirements for the area to submit attainment demonstrations and associated Reasonably Available Control Measures (RACM), Reasonable Further Progress (RFP) plans, contingency measures for failure to attain or make reasonable progress, and other planning State Implementation Plans (SIPs) related to attainment of the 2015 ozone NAAQS, for as long as the area continues to attain the 2015 ozone NAAQS.
The Environmental Protection Agency (EPA) is proposing to determine under the Clean Air Act (CAA) that the Missouri portion of the St. Louis, MO-IL nonattainment area (hereafter also referred to, respectively, as the "St. Louis area" or "area") has achieved clean data for the 2015 ozone National Ambient Air Quality Standards (NAAQS or standard). This determination of clean data is based upon complete, quality-assured, and certified ambient air monitoring data for the 2023-2025 design value period showing that the Missouri portion of the area achieved attainment of the 2015 ozone NAAQS. The 2023-2025 design value relies upon EPA concurrence on a portion of the exceptional events request as submitted by the Missouri Department of Natural Resources (MoDNR) on November 3, 2025, and concurred on by the EPA on January 27, 2026. Therefore, the EPA is proposing to approve Missouri's November 3, 2025, Clean Data Determination (CDD) request. If finalized, this proposed CDD would suspend the obligations of the State of Missouri to submit certain nonattainment area planning requirements for as long as the Missouri portion of the St. Louis area continues to attain the 2015 ozone NAAQS. In a separate action, the EPA is proposing a similar determination for the Illinois portion of the St. Louis area.
The Environmental Protection Agency (EPA) is approving with conditions, no-migration variances for nine categories/groups of wastes, containing up to a combined 100 temporary disposal units ("put piles") at any one time, from the Resource Conservation and Recovery Act (RCRA) Land Disposal Restrictions (LDR) standards at Clean Harbors' Lone Mountain (Clean Harbors) commercial treatment, storage and disposal facility (TSDF) in Waynoka, Oklahoma. These variances will allow Clean Harbors to temporarily store treated hazardous wastes that are awaiting LDR compliance verification in put piles within its Subtitle C (hazardous waste) landfill. The petitioner demonstrated, to a reasonable degree of certainty, that there will be no migration of hazardous constituents from the put piles for as long as the wastes remain hazardous. Additionally, once LDR compliance is verified, the put piles will be disposed within the onsite RCRA hazardous waste landfill area and will be subject to the conditions set out in the Compliance Monitoring Plan section of this document.
The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Missouri State Implementation Plan (SIP) and the Missouri Operating Permits Program related to Reporting Emission Data, Emission Fees, and Process Information. The revisions set emission fees and a base fee for calendar years 2025-2028 and beyond, add 1-Bromopropane to the category 1 Hazardous Air Pollutant list in table 1, update two publication dates for material that is incorporated by reference and make minor administrative changes to the rule. These revisions do not impact the stringency of the SIP or have an adverse effect on air quality. The EPA's final 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 approving a State Implementation Plan (SIP) revision submitted by the State of Connecticut. This action consists of revisions to Regulations of Connecticut State Agencies (RCSA) sections 22a-174-22e and 22a-174-22f, primarily to add compliance dates for sources brought into the applicability of these sections due to a change in the definition of "severe non-attainment area for ozone." The definition change had previously been approved into Connecticut's SIP. This action is being taken in accordance with the Clean Air Act.
Under the Clean Air Act (CAA), EPA may approve State or local rules or programs to be implemented and enforced in place of certain otherwise applicable Federal rules, emissions standards, or requirements. On October 6, 2025, the Missouri Department of Natural Resources (MoDNR), on behalf of the State of Missouri, requested delegation of a partial CAA Risk Management Program (RMP) for agricultural anhydrous ammonia facilities. The request was supplemented by MoDNR on October 9, 2025, and on October 27, 2025. The EPA has determined that MoDNR's request meets CAA requirements for delegation of a partial program, and the EPA is proposing to approve the request.
The Environmental Protection Agency (EPA) is approving a revision to the Michigan State Implementation Plan (SIP) as meeting the reasonable further progress (RFP) requirements of the Clean Air Act (CAA) for the Allegan County (partial county), Berrien County, and Muskegon County (partial county) Moderate nonattainment areas for the 2015 ozone national ambient air quality standard (NAAQS). The EPA is also approving updated 2017 base year emissions inventories and is finding adequate and approving the 2023 motor vehicle emissions budgets (budgets) associated with the Allegan County, Berrien County, and Muskegon County Moderate ozone nonattainment RFP demonstrations. The EPA is approving these portions of the State's SIP submission pursuant to section 110 and part D of the CAA, and EPA's regulations. The EPA proposed to approve this action on December 11, 2025, and received no adverse comments.
