Senate Bill 205 Requirements - Stormwater Discharge Compliance

Senate Bill 205 (2019) was signed by Governor Gavin Newsom on October 2, 2019 and became effective January 1, 2020. This Senate Bill added sections 16000.3 and 16100.3 to the Business and Professions Code and section 13383.10 to the Water Code, and requires a person applying to a city or county for a new or renewed business license to demonstrate enrollment in a National Pollutant Discharge Elimination System (NPDES) storm water permit, if such a permit is required. Prior to the issuance or renewal of a business license, the city or county must determine whether the applicant is required to enroll in the NPDES General Permit for Storm Water Discharges Associated with Industrial Activities (Industrial General Permit) and, if so, ensure such enrollment has occurred. This will substantially increase the number of compliant industrial facilities and will reduce the spread of pollutants in storm water associated with industrial activities.
