This joint resolution proposes to disapprove a specific rule issued by the Environmental Protection Agency (EPA) concerning updates to new chemicals regulations under the Toxic Substances Control Act (TSCA). Utilizing the authority granted by chapter 8 of title 5, United States Code, commonly known as the Congressional Review Act, the resolution seeks to prevent the EPA's rule, published on December 18, 2024, from having any legal force or effect. If passed by Congress and signed into law, this action would effectively nullify the EPA's regulatory updates regarding new chemicals, meaning the agency's revised regulations would not be implemented, thereby maintaining the status quo prior to the EPA's proposed changes.
