Winston’s Environmental Law Update

In October 2025, we covered the evolving legal landscape surrounding E15 gasoline—a fuel blend containing 15% ethanol—including the EPA's history of issuing short-term emergency waivers to allow summer sales, California's decision to authorize E15 statewide, and the introduction of the bipartisan Nationwide Consumer and Fuel Retailer Choice Act of 2025 in Congress.

On November 10, 2025, the Environmental Protection Agency (EPA or the Agency) issued a proposed rule to revise the reporting and recordkeeping requirements for per- and polyfluoroalkyl substances (PFAS) under Section 8(a)(7) of the Toxic Substances Control Act (TSCA).

The EPA establishes a national standard for gasoline volatility (Reid vapor pressure, or RVP) via section 211(h) of the Clean Air Act to reduce emissions of volatile organic compounds.

The EPA announced on June 11 its intention to repeal three rules under the Clean Air Act that regulate emissions from power plants. This move comes as part of the Trump Administration’s broad energy and regulatory policy shift aimed at expanding domestic energy production, reducing regulatory burdens, and ensuring affordable, reliable energy, as outlined in Executive Order 14154— “Unleashing American Energy” and Executive Order 14156— “Declaring a National Energy Emergency” issued in January 2025. Critics of the Administration’s strategy fear that adverse impacts may result to the energy industry, public health, and the climate.
