Commercial stormwater compliance occupies a place in stormwater management that is less formal than industrial stormwater, but is still subject to requirements enforced by a local agency. Commercial stormwater is not a formal term. It is one Complyrs uses to differentiate from three formal stormwater programs in California: Industrial, Construction and Municipal. Businesses not subject to permitting under the Industrial General Permit (IGP) may need to manage stormwater runoff to comply with local rules and regulations. Local rules and regulations applied to commercial entities originate from conditions of Municipal Separate Storm Sewer System (MS4) permits that are granted by the State Water Resources Control Board. The municipal entities that hold MS4 permits agree to regulate businesses within their jurisdiction as a condition of compliance with the MS4 permit.
Because municipalities regulate businesses as part of an MS4 permit, enforcement efforts and performance standards vary widely between jurisdictions.
Complyr’s Commercial Stormwater compliance program is based, in part, on Best Management Practices (BMPs) by the California Stormwater Quality Association (CASQA). We also use the San Diego County Stormwater Ordinance as a model for requirements.
Because of the delegation of enforcement, the agencies that implement and enforce can vary. Often a local department of public works, environmental health department or local stormwater agency.
