We, the U.S. Fish and Wildlife Service (FWS) and the National Marine Fisheries Service (NMFS; collectively, the "Services") propose to revise portions of our regulations for section 7 of the Endangered Species Act of 1973, as amended (ESA or Act). The proposed revisions to the interagency cooperation regulations confirm the Services' application of statutory requirements for interagency cooperation, while continuing to provide for the conservation of listed species.
The Coast Guard is establishing a permanent security zone in the vicinity of Seaport Manatee facilities and ship berths. This action is necessary to enhance safety and protect vessels, facilities and infrastructure from potential threats. This regulation will allow for controlled access of authorized vessels and facility personnel within the security zone.
The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the State of Rhode Island. This revision removes requirements for Stage II vapor recovery equipment at gasoline dispensing facilities (GDFs). This revision also includes minor updates to Stage I vapor recovery regulatory amendments. The intended effect of this action is to approve Rhode Island's revised vapor recovery regulations. This action is being taken in accordance with the Clean Air Act.
The Environmental Protection Agency (EPA) is approving a revision to the Minnesota State Implementation Plan (SIP) with updates to Minnesota's air program rules. The Minnesota Pollution Control Agency (MPCA) submitted the request to EPA on October 1, 2021. The revision to Minnesota's air quality rules reflects changes that have occurred since July 2020. EPA proposed to approve this submittal, which will result in consistent requirements of rules at both the State and Federal level, on July 16, 2025, and received no adverse comments.
The Environmental Protection Agency (EPA) is proposing to approve a request from the Commonwealth of Pennsylvania to redesignate the Allegheny County, Pennsylvania nonattainment area (Allegheny County Area) to attainment for the 2012 annual fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standard (NAAQS or standard). The EPA has already approved, as a revision to the Pennsylvania state implementation plan (SIP), a maintenance plan that demonstrates maintenance of the 2012 annual PM<INF>2.5</INF> NAAQS through 2035 in the Allegheny County Area. The redesignation request was 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 Clean Air Act (CAA).
The Environmental Protection Agency (EPA) is proposing to approve a Clean Air Act (CAA) operating permit program revision submitted by the State of Maine. The revisions include minor changes to Maine's operating permit program that are considered clarifications, that correct grammar, that codify longstanding practices, or that are necessary to utilize an expected future electronic application system. The revisions also include provisions allowing the public comment period on a draft permit to run concurrently with EPA's review of a proposed permit. The intended effect of EPA's action is to propose approval of Maine's revisions. This action is being taken under the CAA.
The Environmental Protection Agency (EPA) is proposing to approve revisions to the State of New Hampshire's Clean Air Act (CAA) title V operating permit program. These revisions amend the definitions of "hazardous air pollutant" and "regulated air pollutant" in New Hampshire regulations to remain consistent with Federal permitting and air toxics requirements in accordance with the CAA.
The Environmental Protection Agency (EPA) is taking final action to approve a revision to the Eastern Kern Air Pollution Control District (EKAPCD or "District") portion of the California State Implementation Plan (SIP). This revision concerns emissions of oxides of nitrogen (NO<INF>X</INF>) from stationary gas turbines. We are approving a local rule that regulates these emissions sources under the Clean Air Act (CAA or "Act").
The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Connecticut. This revision updates state regulations containing ambient air quality standards (AAQS) for ozone to be consistent with EPA's national ambient air quality standards (NAAQS). In addition, this update clarifies the volatile organic compound (VOC) calculation methods for adhesive and sealant products. The intended effect of this action is to propose approval of these regulations into the Connecticut SIP. This action is being taken under the Clean Air Act.
The Environmental Protection Agency (EPA) previously granted the State of Connecticut's request to reclassify the Greater Connecticut ozone nonattainment area from Moderate to Serious under the 2015 ozone National Ambient Air Quality Standards (NAAQS). That request, however, did not include areas governed by the Mashantucket Pequot Tribal Nation and the Mohegan Indian Tribe that are located within this nonattainment area. Given that ozone monitoring data indicate that the Greater Connecticut area failed to attain the 2015 ozone NAAQS by the applicable attainment date, we are proposing to find that these tribal portions of the area did not attain the standards by the attainment date and to reclassify those portions of the area by operation of law to Serious nonattainment for the 2015 ozone NAAQS. This action, if finalized as proposed, would fulfill the EPA's statutory obligation to determine whether the Mashantucket Pequot Tribal Nation and the Mohegan Indian Tribe portions of the Greater Connecticut area attained the NAAQS by the attainment date. This action also solicits public comment on EPA's prior action on CT DEEP's request to exclude event-influenced air quality monitoring data from regulatory decisions. EPA is required to provide an opportunity for public comment on the claimed exceptional events and all supporting data. This proposed action provides the public with an opportunity to comment on the claimed exceptional events, all supporting documents, and the EPA's July 22, 2024 concurrence and nonconcurrence with CT DEEP's request.
The Environmental Protection Agency (EPA) is finalizing approval of a state implementation plan (SIP) revision submitted by the State of South Carolina, through the South Carolina Department of Environmental Services (SCDES, formerly the "South Carolina Department of Health and Environmental Control"), on September 26, 2023. The SIP revision includes the State's plan for maintaining the 2008 ozone National Ambient Air Quality Standard (NAAQS) through 2036 for the South Carolina portion of the bi-state Charlotte-Rock Hill, North Carolina-South Carolina 2008 8-hour ozone nonattainment area (the entire area is hereinafter referred to as the "bi-State Charlotte Area" and the South Carolina portion is hereinafter referred to as the "York County Area"). EPA is approving and incorporating this maintenance plan, including the 2018 and 2036 motor vehicle emission budgets (budgets) for nitrogen oxides (NO<INF>X</INF>) and volatile organic compounds (VOC) for the York County Area, into the SIP. EPA is finalizing approval because the York County Area maintenance plan provides for the maintenance of the 2008 8-hour ozone NAAQS within the Area through the end of the second 10-year portion of the maintenance period. Additionally, EPA finds the 2018 and 2036 budgets for the York County Area adequate for the purposes of transportation conformity.
This regulation establishes tolerances for residues of isocycloseram (CASRN 2061933-85-3) in or on multiple commodities which are identified and discussed later in this document. Under the Federal Food, Drug, and Cosmetic Act (FFDCA), Syngenta Crop Protection, LLC submitted a petition to EPA requesting that EPA establish a maximum permissible level for residues of this pesticide in or on the identified commodities.
The Environmental Protection Agency (EPA) is proposing to approve a request from the Allegheny County Health Department (ACHD) for delegation of authority to implement and enforce the Federal Plan Requirements for Sewage Sludge Incineration (SSI) units within Allegheny County in the Commonwealth of Pennsylvania. On April 29, 2016, the EPA promulgated the Federal Plan for SSI units to fulfill the requirements of sections 111(d)/129 of the Clean Air Act (CAA). The Federal Plan addresses the implementation and enforcement of the emission guidelines applicable to existing SSI units located in areas not covered by an approved and currently effective state plan. The Federal Plan imposes emission limits and other control requirements for existing affected SSI facilities which will reduce designated pollutants.
The Environmental Protection Agency (EPA) is approving 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 (HAPs). This action is being taken under the Clean Air Act.
PHMSA is withdrawing its proposed rulemaking that would have increased registration fees for persons who transport, or offer for transportation, certain categories and quantities of hazardous materials.
The FAA is superseding Airworthiness Directive (AD) 2024-09- 02, which applies to all Leonardo S.p.a. Model AW169 helicopters. AD 2024-09-02 required replacing certain aft float assemblies or, as an alternative, deactivating the emergency flotation system (EFS). AD 2024-09-02 also prohibited the installation of certain forward and aft float assemblies. Since the FAA issued AD 2024-09-02, the FAA has determined that replacing additional forward and aft float assemblies is necessary. This AD retains all the actions of AD 2024-09-02 and also requires replacing certain forward and aft float assemblies within 24 months or during the next accomplishment of a certain maintenance task. The FAA is issuing this AD to address the unsafe condition on these products.
The Environmental Protection Agency (EPA) is proposing to approve the regional haze state implementation plan (SIP) revision submitted by Rhode Island on March 7, 2025, as satisfying applicable requirements under the Clean Air Act (CAA) and EPA's Regional Haze Rule (RHR) for the program's second implementation period. Rhode Island'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. EPA is also proposing to approve the remaining element of Rhode Island's September 23, 2020, infrastructure SIP submittal for the 2015 ozone National Ambient Air Quality Standards (NAAQS). The proposed approval of Rhode Island's second implementation period regional haze plan addresses infrastructure SIP requirements related to visibility protection. The EPA is taking this action pursuant to sections 110 and 169A of the Clean Air Act.
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 the Athens Generating Plant, located at 9300 US Route 9 West, Athens, NY 12015 ("Athens" or "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 Oxides of Nitrogen (NO<INF>X</INF>) emissions from the relevant Facility sources, which are identified as three combined-cycle Westinghouse model 501G combustion turbines with associated heat recovery steam generators and steam turbines (identified as Emission Units U-00001, U-00002, and U- 00003 in the Facility's Title V permit and New York's submission). This SSSIP revision is intended to implement NOx RACT for the relevant Facility sources in accordance with the requirements for implementation of the 2008 and 2015 ozone NAAQS. The EPA proposes to determine that this action will not interfere with ozone NAAQS requirements and that it meets all applicable requirements of the Clean Air Act (CAA).
Two regional fishery management councils have submitted to NMFS for review, and consideration of approval and implementation by NMFS, amendments to four fishery management plans (FMPs) in the Gulf of America (Gulf), South Atlantic, and Atlantic, referenced here as the Commercial Electronic Logbook Amendments. If approved by the Secretary of Commerce (Secretary) and implemented by NMFS, the Commercial Electronic Logbook Amendments would require submission of certain commercial fishing logbooks in an electronic format rather than the current paper format. These FMP amendments also propose minor changes to some of the required data fields in the logbooks determined to be necessary to successfully transition from paper to electronic reporting. The purpose of the Commercial Electronic Logbook Amendments is to increase the accuracy and efficiency of fisheries data that NMFS receives from federally permitted fishermen participating in the applicable commercial fisheries that occur in the Gulf, South Atlantic, and Atlantic.
The Postal Service (USPS[supreg]) is proposing to amend Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM[supreg]) in various sections to implement shape-based labeling lists for SCF letters, flats, and parcels.
The Environmental Protection Agency (EPA) is proposing to approve a limited maintenance plan (LMP) submitted by the Delaware Department of Natural Resources and Environmental Control (DNREC). This LMP is a revision to Delaware's state implementation plan (SIP) and addresses the New Castle County portion of the Philadelphia-Wilmington, PA-NJ-DE area (Philadelphia Area). The EPA is proposing to approve the New Castle County portion of the Philadelphia Area LMP because it provides for the maintenance of the 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standard (NAAQS) through the end of the second 10-year maintenance period. In addition, the EPA is initiating the process to find the LMP adequate for transportation conformity purposes. This action is being taken under the Clean Air Act (CAA).
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model H160-B helicopters. This proposed AD was prompted by a report that several self-locking nuts of the window jettisoning system could be loosened by hand due to a non-conformity in the cable kit. This proposed AD would require modifying an affected window into a serviceable window. This proposed AD would also prohibit installing an affected window or an affected door on any helicopter. The FAA is proposing this AD to address the unsafe condition on these products.
The Environmental Protection Agency (EPA) is extending the comment period for the proposed rulemaking entitled "Air Plan Approval; AK; Regional Haze Plan for the Second Implementation Period," that published on October 30, 2025. This will allow interested persons additional time to prepare and submit comments.
In this document, the Federal Communications Commission (Commission) seeks comment on proposed rule changes that would support and accelerate the nation's ongoing market-based broadcast television transition to ATSC 3.0 (or Next Gen TV). The document tentatively concludes that the Commission should eliminate the simulcasting requirement for stations that transition to 3.0, while continuing to permit simulcasting on a voluntary, simplified basis. It also seeks comment on a range of closely related issues and other matters touching on the Next Gen TV transition.
This regulation establishes, modifies, and revokes tolerances for residues of glufosinate (CASRN 77182-82-2) in or on rice and tea commodities. Under the Federal Food, Drug, and Cosmetic Act (FFDCA), BASF Corporation submitted a petition to EPA requesting that EPA establish a maximum permissible level for residues of this pesticide on in or on the identified commodity(ies).
The Postal Service is amending Mailing Standards of the United States Postal Service, Domestic Mail Manual (DMM), to reflect changes to certain prices for competitive products. There are no mailing standards changes scheduled for competitive products.
The Environmental Protection Agency (EPA) is proposing to approve a request from the Minnesota Pollution Control Agency (MPCA) to revise its State Implementation Plan (SIP) by updating information for the Metropolitan Council Environmental Service (MCES) Metropolitan Council Wastewater Treatment Plant (Metro Plant) in Ramsey County, Minnesota. This SIP revision is being proposed in conjunction with an amendment to a part 70 permit maintaining federally enforceable title I SIP conditions. This SIP revision would result in a reduction of allowable emissions of particulate matter less than 10 microns (PM<INF>10</INF>) emitted by the facility.
The Environmental Protection Agency (EPA) is approving an element of a State Implementation Plan (SIP) submission from Michigan regarding the infrastructure requirements of section 110 of the Clean Air Act (CAA) for the 2015 ozone National Ambient Air Quality Standards (NAAQS). The infrastructure requirements ensure that the structural components of each State's air quality management program are adequate to meet CAA requirements. This action pertains to CAA section 110(a)(2)(E)(ii).
The Environmental Protection Agency (EPA) is proposing to approve the negative declarations submitted by the District of Columbia Department of Energy and Environment (DCDOEE) on July 19, 2024 and August 28, 2024. The negative declarations submitted by the DCDOEE certify that there are no existing large municipal waste combustors (LMWC), crude oil and natural gas facilities, or electric utility generating units subject to sections 111(d) and 129 of the Clean Air Act (CAA) within the jurisdiction of the District of Columbia.
The U.S. Environmental Protection Agency (EPA) and the U.S. Department of the Army ("the agencies") are publishing for public comment a proposed rule revising the regulations defining the scope of waters federally covered under the Federal Water Pollution Control Act, as amended, also known as the Clean Water Act, in light of the U.S. Supreme Court's 2023 decision in Sackett v. Environmental Protection Agency. With this proposed rule, the agencies intend to provide greater regulatory certainty and increase Clean Water Act program predictability and consistency by clarifying the definition of "waters of the United States." This proposed rule is also intended to implement the overall objective of the Clean Water Act to restore and maintain the quality of the Nation's waters while respecting State and Tribal authority over their own land and water resources.
