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 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) 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 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.
VA is rescinding the interim final rule, Evaluative Rating: Impact of Medication, published on February 17, 2026, and restoring the prior regulatory text. This rescission is effective immediately upon publication.
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by reports that inappropriate tooling was used to torque the bolts securing the baggage door stop fittings, which may have resulted in an improper torque condition. This proposed AD would require performing a torque check of affected bolts, and re-torquing, re-installing, or replacing affected bolts and nuts as applicable. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757-200 and -300 series airplanes. This AD was prompted by reported crack findings on airplanes with scimitar blended winglets. This AD requires inspections for cracks, and repair as applicable. The FAA is issuing this AD to address the unsafe condition on these products.
The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its regulations to augment the existing byproduct material framework to be inclusive of fusion machines. The NRC is proposing requirements that are technology-inclusive to accommodate the wide variety of anticipated fusion machine designs across the National Materials Program. The NRC is also issuing for comment draft guidance for the implementation of this proposed rule, entitled NUREG-1556, Volume 22, "Consolidated Guidance About Materials Licenses: Program- Specific Guidance About Fusion Machine Licenses." The NRC will conduct at least one public meeting to promote full understanding of the proposed rule and to facilitate public comments. We seek comment on all aspects of this proposed rule.
The Board of Governors of the Federal Reserve System (Board) is inviting public comment on a notice of proposed rulemaking (proposal or proposed rule) that would codify the removal of reputation risk from the Board's supervisory programs. The proposal would prohibit the Board from encouraging or compelling Board-supervised banking organizations to deny or condition the provision of banking or other financial products or services to an individual or business based on their constitutionally protected political or religious beliefs, associations, speech, or conduct, or based on involvement by the individual or business in politically disfavored but lawful business activities perceived to present reputation risk.
On January 21, 2026, the U.S. Department of Energy ("DOE") published a notice of proposed rulemaking ("NOPR") seeking to amend certain regulations for worker safety and health to expedite the review, approval, and deployment of advanced reactors under DOE's jurisdiction, including qualified test reactors in DOE's reactor pilot program consistent with a recent Executive order. The NOPR provided an opportunity for submitting written comments, data, and information by February 20, 2026. By letter dated February 4, 2026, the American Federation of Labor and Congress of Industrial Organizations ("AFL- CIO") requested a 45-day extension to the comment period. DOE has reviewed this request and is re-opening the public comment period until March 23, 2026.
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-1A10, BD-700-1A11, and BD- 700-2A12 airplanes. This proposed AD was prompted by reports that certain seat frames were assembled without applying Loctite in certain locations of concern. This proposed AD would require a modification to the non-locking fastener joints of the seat frame assembly. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA is adopting a new airworthiness directive (AD) for all Leonardo S.p.A. Model AB139 and AW139 helicopters. This AD was prompted by a report of interference found in the overhead panel area between the electrical cables and adjacent connectors. This AD requires repetitively inspecting the overhead panel and, depending on the results, repairing or replacing the damaged wires. This AD also requires modifying the overhead panel on certain helicopters. The FAA is issuing this AD to address the unsafe condition on these products.
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.
We, the U.S. Fish and Wildlife Service (Service), propose to remove Geocarpon minimum from the Federal List of Endangered and Threatened Plants. Our review indicates that the threats to Geocarpon minimum have been eliminated or reduced to the point that the species no longer meets the definition of an endangered or threatened species under the Endangered Species Act of 1973, as amended (Act). Accordingly, we propose to delist Geocarpon minimum. This proposed rule completes the 5-year status review for the species. If we finalize this rule as proposed, the prohibitions and conservation measures provided by the Act, particularly through sections 4 and 7, would no longer apply to Geocarpon minimum.
The FAA is correcting a Notice of Proposed Rulemaking (NPRM) that was published in the Federal Register. That NPRM proposed to issue an airworthiness directive (AD) that would apply to all Leonardo S.p.a. Model AB139, AW139, and AW189 helicopters. As published, the references to the incorporated material in paragraphs (h)(1) through (4), and paragraph (i) of the NPRM reference an incorrect mandatory continuing airworthiness information (MCAI) identifier. This document corrects that error. In all other respects, the original document remains the same; however, for clarity, the FAA is publishing the entire proposed rule in the Federal Register.
In this document, the Federal Communications Commission (Commission) modifies its rules regarding the delegated authority of the Chairman and the Managing Director to settle claims filed against the agency under the Federal Tort Claims Act (FTCA) and the Military Personnel and Civilian Employees' Claims Act (MPCECA).
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model H160-B helicopters modified by Supplemental Type Certificate (STC) SR00223IB. This proposed AD was prompted by reports of various deficiencies on the parts installed on the jettisonable window system. This proposed AD would require removing the jettisonable window and, depending on the removal results, replacing the locking fingers; inspecting and replacing any missing retaining rings; and inspecting the left-hand (LH) side and right-hand (RH) side emergency handle latch covers (covers) and, depending on the inspection results, replacing the covers or reinstalling airworthy covers. This proposed AD would also require performing repetitive lubrication of the locking fingers installed on the windows jettisonable system and repetitive operational tests of the windows jettisonable system after each lubrication. Additionally, this proposed AD would require modifying the helicopter by replacing each cover and would prohibit the installation of certain window aesthetic covers or electrochromic windows unless certain requirements are met. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA proposes to adopt a new airworthiness directive (AD) for all ATR--GIE Avions de Transport R[eacute]gional Model ATR42-200, - 300, and -320 airplanes. This proposed AD was prompted by a report of an occurrence of a flap asymmetry detector and flap interconnection shaft having worn splines and not engaging mechanically. This proposed AD would require a special detailed inspection (SDI) of the affected flap asymmetry detection mechanism, and applicable corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
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.
This action establishes the Helena (HLN), MT, Very High Frequency Omnidirectional Range/Tactical Air Navigation (VORTAC) as a Domestic Low Altitude Reporting Point in the state of Montana.
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.
In response to a court order, we, the U.S. Fish and Wildlife Service (Service) are initiating a new 12-month petition finding process for the lesser prairie-chicken (Tympanuchus pallidicinctus) under the Endangered Species Act of 1973, as amended (Act). We ask the public to submit to us any information relevant to the status of the lesser prairie-chicken or its habitat.
In response to a court order, we, the U.S. Fish and Wildlife Service (Service) are removing the northern and the southern distinct population segments (DPSs) of the lesser prairie-chicken (Tympanuchus pallidicinctus) from the Federal List of Endangered and Threatened Wildlife. Additionally, we are rescinding the rule issued under section 4(d) of the Act for the northern DPS. As a result of the court's orders, the regulatory protections under the Endangered Species Act of 1973, as amended (Act) no longer apply to either DPS.
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.
In this document, the Federal Communications Commission (Commission) seeks comment on establishing eligibility restrictions and a limit on the number of applications that each applicant may file in the first-ever filing window for applications for new noncommercial educational (NCE) reserved band FM translator station construction permits. The proposed eligibility restrictions and application caps are intended to promote efficiency, curb speculative applications, and preserve spectrum for future secondary services.
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 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 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 Mine Safety and Health Administration (MSHA) is amending its published regulations to update the Agency's Headquarters address from Arlington, VA to its new location in Washington, DC.
This rule revokes the 2021 interim final rule and 2024 final rule requiring that public housing agencies (PHAs) and owners of properties receiving project-based rental assistance (PBRA) provide certain tenants with 30-day notification prior to termination of lease for nonpayment of rent. Regulatory requirements for notice of termination for nonpayment of rent will return to pre-2021 requirements, which range from 5 days to 30 days for HUD programs and depend on state and local laws. This rule also removes requirements from the 2021 and 2024 rules related to information in termination notices.
