TC-3 - Entrance/'Outlet Tire Wash <br /> ■ Provide a drainage ditch that will convey the runoff from the wash area to a sediment <br /> trapping device. The drainage ditch should be of sufficient grade;width, and depth to carry <br /> the wash runoff. <br /> ■ Use hoses with automatic shutoff nozzles to prevent hoses from being left on. <br /> ■ Require that all employees, subcontractors, and others that leave the site with mud caked <br /> tires and undercarriages to use the wash facility. <br /> ■ Implement SC-7,Street Sweeping and Vacuuming, as needed. <br /> Costs <br /> Costs are low for installation of wash rack. <br /> Inspection and Maintenance <br /> ■ Inspect and verify that activity—based BMPs are in place prior to the commencement of <br /> associated activities. While activities associated with the BMP are underway, inspect weekly <br /> during the rainy season and of two-week intervals in the non-rainy season to verify <br /> continued BMP implementation. <br /> ■ Inspect BMPs subject to non-stormwater discharge daily while non-stormwater discharges <br /> occur. <br /> ■ Remove accumulated sediment in.wash rack and/or sediment trap to maintain system <br /> performance. <br /> ■ Inspect routinely for damage and repair as needed. <br /> References <br /> Blueprint for a Clean Bay: Best Management Practices to Prevent Stormwater Pollution from <br /> Construction Related Activities; Santa Clara Valley Nonpoint Source Pollution Control Program, <br /> 1995. <br /> Coastal Nonpoint Pollution Control Program; Program Development and Approval.Guidance, <br /> Working Group,Working Paper; USEPA,April 1992. <br /> Manual of Standards of Erosion and Sediment Control Measures,Association of Bay Area <br /> Governments,May 1995• <br /> Stormwater Quality Handbooks Construction Site Best Management Practices (BMPs)Manual, <br /> State of California Department of Transportation(Caltrans),November 2000. <br /> Stormwater Management for Construction Activities,Developing Pollution Prevention Plans <br /> and Best Management Practices, EPA 832-R-92005; USEPA,April 1992. <br /> 2 of 3 California Stormwater BMP Handbook January 2003 <br /> Construction. <br /> www.cabmphandbooks.com <br />
