On November 19, 2025, the Washington Suburban Sanitary Commission (WSSC) repealed Chapter 14.05 of the WSSC Code of Regulations, which codified the Industrial Discharge Control (IDC) Program’s Enforcement Response Plan (ERP) as a regulation. The ERP is better described as an Internal Operating Procedure that only affects one unit in the Commission and does not contain regulations affecting persons/entities outside of WSSC Water. IDC’s ERP will continue to be shared on the IDC Program website: www.wsscwater.com/idc.
THE EFFECTIVE DATE OF THE AMENDED REGULATION IS JANUARY 9, 2026.
