SC-10 Non-Stormwater Discharges <br />- Types and quantities (in some cases) of wastes <br />- Patterns in time of occurrence (time of day/night, month, or year) <br />- Mode of dumping (abandoned containers, "midnight dumping" from moving vehicles, <br />direct dumping of materials, accidents/spills) <br />- Responsible parties <br />One of the keys to success of reducing or eliminating illegal dumping is increasing the number of <br />people at the facility who are aware of the problem and who have the tools to at least identify the <br />incident, if not correct it. Therefore, train field staff to recognize and report the incidents. <br />What constitutes a "non-stormwater" discharge? <br />■ Non-stormwater discharges to the stormwater collection system may include any water used <br />directly in the manufacturing process (process wastewater), air conditioning condensate and <br />coolant, non -contact cooling water, cooling equipment condensate, outdoor secondary <br />containment water, vehicle and equipment wash water, sink and drinking fountain <br />wastewater, sanitary wastes, or other wastewaters. <br />Permit Requirements <br />■ Facilities subject to stormwater permit requirements must include a certification that the <br />stormwater collection system has been tested or evaluated for the presence of non- <br />stormwater discharges. The State's General Industrial Stormwater Permit requires that non- <br />stormwater discharges be eliminated prior to implementation of the facility's SWPPP. <br />Performance Evaluation <br />■ Review annually internal investigation results; assess whether goals were met and what <br />changes or improvements are necessary. <br />■ Obtain feedback from personnel assigned to respond to, or inspect for, illicit connections <br />and illegal dumping incidents. <br />References and Resources <br />California's Nonpoint Source Program Plan hU://www.swreb.ca.gov/nns/index.html <br />Clark County Storm Water Pollution Control Manual <br />htL-D://www.co.clarkwa.us/pubworks/bmpman.pdf <br />King County Storm Water Pollution Control Manual http://dnr.metroke.gov/wlr/dss/spcm.htm <br />Santa Clara Valley Urban Runoff Pollution Prevention Program http: //www.scvurVDp.org <br />The Storm Water Managers Resource Center htto://www.stormwatereenter.net/ <br />6 of 6 California Stormwater BMP Handbook January 2003 <br />Industrial and Commercial <br />www.cabmphandbooks.com <br />
