Significant New Use Rules on Certain Chemical Substances (24-5.5e); Correction
EPA is making a correction to a final rule that appeared in the Federal Register on August 26, 2026. The final rule established significant new use rules (SNURs) under the Toxic Substances Control Act (TSCA) for chemical substances that were the subject of premanufacture notices (PMNs) and Orders issued by EPA pursuant to TSCA. Subsequent to the publication, the Agency identified an error in a chemical name.
Significant New Use Rules on Certain Chemical Substances (26-1)
EPA is issuing 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 to notify EPA at least 90 days before commencing the manufacture (defined by statute to include import) or processing of any of these chemical substances for an activity that is designated as a significant new use in the SNUR. 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.
Trichloroethylene (TCE); Regulation Under the Toxic Substances Control Act (TSCA); Compliance Date Extensions

Clean Water Act Hazardous Substance Facility Response Plans: Compliance Date Delay and Changes To Reflect Administration Policy
The Environmental Protection Agency (EPA) is finalizing an extension to the compliance date for Facility Response Plans (FRPs) required by the Clean Water Act (CWA) addressing potential worst-case discharges of CWA hazardous substances. These requirements apply to 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 action is also finalizing language modifications to remove references to climate change and environmental justice in the FRP requirements to align with Executive Order 14148 of January 20, 2025. EPA is revising the compliance deadlines in light of serious concerns that facilities may be unable to comply with the relevant requirements by the existing deadline. These changes are necessary to allow the Agency to consider implementation and compliance assistance tools that regulated facilities may be able to take advantage of when complying with the new requirements, and to ensure proper planning for all communities while promoting a science-based and risk-based approach to planning. EPA also recognizes that a delay would provide time for EPA to consider whether revisions are necessary before facilities must comply.

Notice of Availability for Public Comment; Reconsideration of Air Plan Disapproval; Texas; Control of Air Pollution From Visible Emissions and Particulate Matter
On August 20, 2020, the State of Texas, through the Texas Commission on Environmental Quality (TCEQ), submitted a state implementation plan (SIP) to the Environmental Protection Agency (EPA). The SIP submission addressed emissions during planned maintenance, startup, and shutdown (MSS) activities for certain electric generating units (EGUs) and included requirements intended to address visible emissions (opacity) and particulate matter (PM) emissions during planned MSS activities. These requirements were included in eight Agreed Orders (AOs) issued by TCEQ to the affected EGUs, which were provided in the 2020 SIP submission. The EPA disapproved the 2020 SIP submission on December 20, 2024, after determining that the requirements contained in these AOs did not meet the Clean Air Act's (CAA) enforceability requirements or the requirement that emission limitations must apply on a continuous basis. The EPA subsequently granted reconsideration of the disapproval on May 11, 2026. Through this notice of availability, the EPA is providing an opportunity for the public to provide additional information to the Agency during the reconsideration process. Since the EPA disapproved the 2020 SIP submission, TCEQ has rescinded four of the eight AOs. The EPA is soliciting public comments on the impact of these recissions on the EPA's prior evaluation of the SIP submission as well as any other information that would further inform the Agency's reconsideration of the 2024 disapproval action.

Rescission of the Greenhouse Gas Findings for Fossil Fuel-Fired Power Plants and Repeal of Regulations for Power Plant Greenhouse Gas Emissions Under Clean Air Act Section 111
In this action, the U.S. Environmental Protection Agency (EPA) is supplementing its proposal to repeal all greenhouse gas (GHG) emission standards for fossil fuel-fired electric generating units (EGUs) to effectuate the best reading of Clean Air Act (CAA) section 111. We propose that CAA section 111 does not authorize the EPA to regulate emissions from power plants in response to global climate change concerns. For the multiple and independent reasons described herein, this additional rationale would also require rescinding the Administrator's contrary findings and determinations in 2015 and repealing all associated 2015 and 2024 GHG standards for the fossil fuel-fired EGU source category. In a separate action published concurrently with this supplemental notice, the EPA is finalizing the repeal of certain 2024 GHG standards for the fossil fuel-fired EGU source category on distinct legal and technical grounds. We are not reopening that final rule. Nor are we soliciting further comment on those issues through this supplemental notice, except to the extent that commenters believe the final rule bears on the distinct questions of statutory authority addressed herein.
