Clean Water Act Hazardous Substance Facility Response Plans
Proposed Planning Requirements
On March 28, 2022, EPA proposed planning requirements for worst case discharges of hazardous substances.
EPA is developing new requirements for certain facilities to plan for worst case discharges of hazardous substances under the Clean Water Act. A worst case discharge is the largest foreseeable discharge in adverse weather conditions, including those due to climate change.
The agency is currently reviewing comments received during the public comment period for the proposed rule, which closed on July 26, 2022.
If the requirements are finalized, the response plans should be consistent with the NCP and Area Contingency Plan.
