EPA is repealing most provisions of the 2024 Carbon Pollution Standards for greenhouse gas (GHG) emissions from fossil fuel-fired electric generating units (EGUs) based on a reevaluation of the best system of emission reduction for the relevant subcategories. Specifically, the EPA is repealing the emission guidelines for existing fossil fuel-fired steam generating units, the carbon capture and sequestration/storage (CCS)-based standards for coal-fired steam generating units undertaking a large modification, and the CCS-based standards for new base load stationary combustion turbines (i.e., Phase 2 standards). In a separate action published concurrently with this final rule, the EPA is issuing a supplemental proposal soliciting comment on additional reasons to rescind all GHG emission requirements for fossil fuel-fired EGUs to effectuate the best reading of Clean Air Act (CAA) section 111 and ensure consistency with applicable principles of administrative law beyond those reasons on which the EPA solicited comment in the June 2025 notice of proposed rulemaking. This final rule is effective on 16 November 2026. POC is Dr. Gregory Honda, tele: (919) 541-2034; and email: honda.gregory@epa.gov. (Federal Register 17 September 2026 [Rule] Pages 58954-59000)

In this action, 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. Comments must be received on or before 2 November 2026. POC is Ms. Lisa Thompson, tele: (919) 541-5158 and email: thompson.lisa@epa.gov. (Federal Register 17 September 2026 [Rule] Pages 59002-59046)

EPA proposes to revise a regulatory definition under the Clean Water Act (CWA) permitting regulations pertaining to discharges in the contiguous zone and ocean. The proposal would revise the regulatory definition of "discharge of a pollutant" to reflect and faithfully implement the statutory exclusion of vessels and other floating craft that add pollutants in the contiguous zone or the ocean from inclusion in the definition of "discharge of a pollutant" or "discharge", and thus, from National Pollutant Discharge Elimination System (NPDES) program requirements. The proposed rulemaking would also make conforming and clarifying changes to the NPDES regulatory exclusion for vessels and other floating craft. The effect of these changes would be that the addition of pollutants by a vessel or other floating craft in the contiguous zone or the ocean that is not secured to the seabed would not be a discharge and would not require CWA NPDES permit authorization to add pollutants to those waters. Comments must be received on or before 19 October 2026.

These two presentations highlight innovative passive-sampling approaches to improve the monitoring and assessment of per- and polyfluoroalkyl substances (PFAS) at Department of War (DoW) sites. The first presentation titled "Ion-Exchange Membranes as Passive Samplers for Diverse PFAS" presents the development of ion-exchange membranes as cost-effective, equilibrium passive samplers capable of measuring time-averaged PFAS concentrations while accounting for variations in pH, temperature, salinity, and dissolved organic matter without requiring site-specific calibrations. The second presentation titled "Demonstration of a Commercially Available Peeper Passive Sampler for PFAS in Sediment" demonstrates the application and validation of a commercially available dialysis-based passive sampler at two DoW aqueous film-forming foam (AFFF) sites, comparing passive-sampling results with traditional sampling methods and PFAS bioavailability measurements. Together, the presentations demonstrate how passive-sampling technologies can provide more efficient, practical, and potentially lower-cost tools for characterizing PFAS concentrations, sources, and bioavailability in water and sediment, while supporting more informed and sustainable monitoring programs.
