EPA Actions

  • The Senate Ratifies the Kigali Amendment, Strengthening U.S. Commitment to Phase Down Hydrofluorocarbons

    On September 21, 2022, the U.S. Senate voted to ratify the 2016 Kigali Amendment to the Montreal Protocol on Substances That Deplete the Ozone Layer. In so doing, the United States formally joins 137 other nations in pledging to reduce the production and consumption of hydrofluorocarbons (HFCs). HFCs are greenhouse gases commonly used in a variety of applications including refrigeration, air-conditioning, building insulation, fire extinguishing systems, refrigerated shipping and aerosols. Because individual HFCs often have significantly greater warming potential than carbon dioxide, HFCs are widely considered one of the most potent drivers of climate change.

  • Supreme Court Issues Opinion in West Virginia v. EPA

  • Biden EPA Doubles Down on Chemical Regulation with PFAS Strategic Roadmap


    Federal efforts to regulate per- and polyfluoroalkyl substances (PFAS) have continued in recent months. Most notably, on October 21, 2021, the United States Environmental Protection Agency (EPA or the Agency) released its PFAS Strategic Roadmap. This document promises to establish a comprehensive, whole-of-agency approach to regulating PFAS, by building off the Trump EPA’s 2019 PFAS Action Plan and related federal initiatives. The Roadmap reflects EPA’s intent to regulate a broader range of activities than those contemplated in the 2019 Action Plan, as well as to accelerate the implementation of activities identified in the earlier Agency document.

  • Time Will Tell If Trump Infrastructure Executive Order Shortens Federal Reviews

    On August 15, President Trump issued an Executive Order that seeks to streamline federal environmental review and approvals of major infrastructure projects by imposing new timelines and procedures. Key provisions create a two-year deadline for completing review and issuing authorizations.

  • Chemicals, Compliance and the Toxic Substances Control Act

    The Toxic Substances Control Act (TSCA) required the compiling of a national register of chemicals that were manufactured in or imported into the United States for a non-exempt commercial purpose, and the first TSCA Inventory in 1979 included approximately 62,000 chemicals. Since then, the Inventory has been expanded to include approximately 90,000 chemicals—a rate of over 700 new chemicals per year.

  • Up in the Air
