EPA Withdraws PFAS Wastewater Permitting Guidance

The EPA recently rescinded 2022 guidance that recommended states use National Pollutant Discharge Elimination System (NPDES) permits, pretreatment programs, and monitoring requirements to identify and reduce discharges of per- and polyfluoroalkyl substances (PFAS). The PFAS memorandum was among five Office of Water guidance documents the EPA identified for rescission following a review of...

EPA Repeals Most 2024 Power Plant Carbon Standards

On September 14, 2026, the EPA announced the repeal of most of the greenhouse gas (GHG) requirements it adopted for fossil fuel-fired power plants in 2024, eliminating carbon capture and natural gas co-firing standards that would have applied to coal- and gas-fired generating units. At the same time, the EPA proposed rescinding the remaining GHG […] The post EPA Repeals Most 2024 Power Plant...

Proposed rule: National Emission Standards for Hazardous Air Pollutants for Gasoline Distribution Facilities and Standards of Performance for Bulk Gasoline Terminals Reconsideration

On May 8, 2024, the U.S. Environmental Protection Agency (EPA) published the National Emission Standards for Hazardous Air Pollutants (NESHAP): Gasoline Distribution Technology Reviews and New Source Performance Standards (NSPS) Review for Bulk Gasoline Terminals final rule ("2024 Final Rule"). The EPA is reconsidering various provisions of the 2024 Final Rule in this proposed rule, including the operating limits and continuous compliance requirements for air emission control devices, and the vapor tightness requirements for gasoline cargo tanks. The EPA is also reconsidering the modification

Notice: 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 prov

Proposed rule: 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 r
