What the agency says

The Environmental Protection Agency (EPA) is proposing to amend its regulations prescribing the manner in which prior notice of citizen suits is to be provided as required under the citizen suit provisions of the Clean Air Act (CAA), the Clean Water Act (CWA), the Safe Drinking Water Act (SDWA), the Noise Control Act (NCA), the Resource Conservation and Recovery Act (RCRA), the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and the Toxic Substances Control Act (TSCA). This proposed rulemaking would generally require electronic service to EPA of Notices of Intent (NOIs) to file a citizen suit under the listed environmental statutes. These proposed revisions would help ensure the Agency receives and processes such NOIs in a timely and efficient manner.
