EPA's Fall 2024 regulatory agenda impacts air, land, water rules
2024-12-16T06:00:00Z
The Environmental Protection Agency (EPA) published the Fall 2024 Semiannual Agenda of Regulatory and Deregulatory Actions on December 13, 2024. The agenda reveals the agency’s upcoming regulatory actions and where each action is in the rulemaking process.
The agenda includes major EPA updates, such as:
- Finalizing a rule to add 16 individual per- and polyfluoroalkyl substances (PFAS) and 15 PFAS categories to the Toxics Release Inventory as chemicals of special concern, making them subject to reporting (final rule expected August 2025);
- Establishing greenhouse gas emission guidelines for existing fossil fuel-fired combustion turbine electric generating units (proposed rule expected February 2025);
- Lowering the 2024 cellulosic biofuel volume and associated percentage standard requirements under the Renewable Fuel Standard program (final rule expected in March 2025);
- Issuing renewal decisions for each of the six applications of hydrofluorocarbons (HFCs) prioritized under the HFC allowance allocation program starting in calendar year 2026 (final rule expected in July 2025); and
- Proposing and finalizing regulations to control unreasonable risks from multiple chemical substances regulated under the Toxic Substances Control Act, like:
- C. I. Pigment Violet 29 (proposed rule expected in April 2025),
- N-methylpyrrolidone (final rule expected in August 2025), and
- 1,4-dioxane (proposed rule expected in October 2025).
This article highlights some of the major rules we’re watching closely. You’ll want to review the entire agenda to learn about all the rulemakings on EPA’s docket. Please note that the agenda dates are tentative; they're when the agency seeks to publish the rulemakings in the Federal Register.
