Implement and maintain a site-specific Stormwater Pollution Prevention Plan (SWPPP) for corporation yards to comply with water quality standards, including: municipal vehicle maintenance, heavy equipment maintenance, vehicle parking areas, and material storage facilities. Each SWPPP must incorporate all applicable BMPs that are described in the California Stormwater Quality Association’s (CASQA) Handbook for Municipal Operations and the Caltrans Storm Water Quality Handbook Maintenance Staff Guide, May 2003, and addenda, as appropriate.
