Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) Data Reporting and Recordkeeping Under the Toxic Substances Control Act (TSCA); Change to Submission Period
Document Number: 2025-08168
Type: Rule
Date: 2025-05-13
Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA or Agency) is amending the data submission period for the Toxic Substances Control Act (TSCA) PFAS reporting rule by changing the start date for submissions and making corresponding changes to the end dates for the submission period, i.e., the data submission period begins on April 13, 2026, and ends on October 13, 2026, with an alternate end date for small manufacturers reporting exclusively as article importers of April 13, 2027. As promulgated in October 2023, the regulation requires manufacturers (including importers) of perfluoroalkyl and polyfluoroalkyl substances (PFAS) in any year between 2011-2022 to report certain data to EPA related to exposure and environmental and health effects. This change is necessary because EPA requires more time to prepare the reporting application to collect this data. The Agency is separately considering reopening certain aspects of the rule to public comment. The delayed reporting date ensures that EPA has adequate time to consider the public comments and propose and finalize any modifications to the rule before the submission period begins.

Air Plan Approval; WA; Southwest Clean Air Agency; Revisions to Excess Emissions, Startup, Shutdown, and General Requirements
Document Number: 2025-07846
Type: Rule
Date: 2025-05-09
Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is approving Washington State Implementation Plan (SIP) revisions to the Southwest Clean Air Agency (SWCAA) air quality regulations submitted by the State of Washington, through the Department of Ecology (Ecology) on June 22, 2023. The revisions were submitted in part to respond to the EPA's June 12, 2015 "SIP call" in which the EPA found a provision in the Washington SIP applicable in the area regulated by SWCAA to be substantially inadequate, providing affirmative defenses that operate to limit the jurisdiction of the Federal court in an enforcement action related to excess emissions during startup, shutdown, and malfunction (SSM) events. The EPA's approval of the SIP revisions to the substantially inadequate provision corrects the SWCAA deficiency identified in the 2015 SSM SIP call and the EPA's January 2022 finding of failure to submit. Washington withdrew some portions of the revisions submitted that were not identified in the 2015 SSM SIP call and therefore the EPA is not approving those withdrawn portions. The EPA proposed to approve this action on December 10, 2024, and received no comments.

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.

Since 1988, the Environmental Protection Agency (EPA) has maintained a Federal Agency Hazardous Waste Compliance Docket ("Docket") under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA).

This document identifies the Federal facilities not previously listed on the Docket and identifies Federal facilities reported to EPA since the last update on October 23, 2024. In addition to the list of additions to the Docket, this document includes a section with revisions of the previous Docket list and a section of Federal facilities that are to be deleted from the Docket.

Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) has prepared a Programmatic Environmental Assessment (PEA) (EPA No. N2025023) to analyze the potential environmental impacts related to the issuance of grant funding for the planning, design, and construction of eligible drinking water, wastewater, and stormwater infrastructure projects, and water quality protection projects under the Community Project Funding (CPF)/Congressionally Directed Spending (CDS), otherwise known as the Community Grants Program.

Based on the environmental impact analysis in the PEA, the EPA has made a preliminary determination that no significant environmental impacts are anticipated from the issuance of Community Grants Program funding. This notice initiates the 30-day review period and invites comments from Federal, State, and local agencies, Tribes, and the public regarding the EPA's preliminary determination.

Air Plan Approval; Ohio; Volatile Organic Compounds
Document Number: 2025-06604
Type: Rule
Date: 2025-04-17
Agency: Environmental Protection Agency
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.
