The drain should be connected to a <br />dead-end sump or to the sanitary sewer. A positive control valve should be installed on <br />the drain. <br />■ For transfer from rail cars to storage tanks that must occur outside, use the following <br />procedures: <br />- Drip pans should be placed at locations where spillage may occur, such as hose <br />connections, hose reels, and filler nozzles. Use drip pans when making and breaking <br />connections. <br />- Drip pan systems should be installed between the rails to collect spillage from tank cars. <br />References and Resources <br />California's Nonpoint Source Program Plan htip::.//www.swreb.ca.gov/nus/index.html <br />Clark County Storm Water Pollution Control Manual <br />http://www.co.clark.wa.us/pubworks/bmpman.pd <br />King County Storm Water Pollution Control Manual http://dnr.metroke.gov/wlr/dss/spem.htm <br />Santa Clara Valley Urban Runoff Pollution Prevention Program hap://www.sevuLRgp.org <br />The Storm Water Managers Resource Center http://www.stormwatereenter.net/ <br />4 of 4 California Stormwater BMP Handbook January 2003 <br />Industrial and Commercial <br />www.cabmphandbooks.com <br />
