Parking/Storage Area Maintenance SC-43 <br />- Do not allow discharges to the storm drain. <br />- Vacuum/pump discharges to a tank or discharge to sanitary sewer. <br />- Appropriately dispose of spilled materials and absorbents. <br />Surface Repair <br />■ Preheat, transfer or load hot bituminous material away from storm drain inlets. <br />■ Apply concrete, asphalt, and seal coat during dry weather to prevent contamination from <br />contacting stormwater runoff. <br />■ Cover and seal nearby storm drain inlets where applicable (with waterproof material or <br />mesh) and manholes before applying seal coat, slurry seal, etc. Leave covers in place until <br />job is complete and all water from emulsified oil sealants has drained or evaporated. Clean <br />any debris from these covered manholes and drains for proper disposal. <br />■ Use only as much water as necessary for dust control, to avoid runoff. <br />■ Catch drips from paving equipment that is not in use with pans or absorbent material placed <br />under the machines. Dispose of collected material and absorbents properly. <br />Inspection <br />■ Have designated personnel conduct inspections of parking facilities and stormwater <br />conveyance systems associated with parking facilities on a regular basis. <br />■ Inspect cleaning equipment/sweepers for leaks on a regular basis. <br />Training <br />■ Provide regular training to field employees and/or contractors regarding cleaning of paved <br />areas and proper operation of equipment. <br />■ Train employees and contractors in proper techniques for spill containment and cleanup. <br />Spill Response and Prevention <br />■ Keep your Spill Prevention Control and Countermeasure (SPCC) Plan up-to-date. <br />■ Place a stockpile of spill cleanup materials where it will be readily accessible or at a central <br />location. <br />■ Clean up fluid spills immediately with absorbent rags or material. <br />■ Dispose of spilled material and absorbents properly. <br />Other Considerations <br />Limitations related to sweeping activities at large parking facilities may include high equipment <br />costs, the need for sweeper operator training, and the inability of current sweeper technology to <br />remove oil and grease. <br />January 2003 California Stormwater BMP Handbook 3 of 4 <br />Industrial and Commercial <br />www.cabmphandbooks.com <br />
