Trash Storage Areas SD-32 <br />Description <br />Trash storage areas are areas where a trash receptacle (s) are <br />located for use as a repository for solid wastes. Stormwater <br />runoff from areas where trash is stored or disposed of can be <br />polluted. In addition, loose trash and debris can be easily <br />transported by water or wind into nearby storm drain inlets, <br />channels, and/or creeks. Waste handling operations that maybe <br />sources of stormwater pollution include dumpsters, litter control, <br />and waste piles. <br />Approach <br />This fact sheet contains details on the specific measures required <br />to prevent or reduce pollutants in stormwater runoff associated <br />with trash storage and handling. Preventative measures <br />including enclosures, containment structures, and impervious <br />pavements to mitigate spills, should be used to reduce the <br />likelihood of contamination. <br />Suitable Applications <br />Design Objectives <br />Maximize Infiltration <br />Provide Retention <br />Slow Runoff <br />Minimize Impervious Land <br />Coverage <br />Prohibit Dumping of Improper <br />Materials <br />0 Contain Pollutants <br />Collect and Convey <br />Appropriate applications include residential, commercial and industrial areas planned for <br />development or redevelopment. (Detached residential single-family homes are typically <br />excluded from this requirement.) <br />Design Considerations <br />Design requirements for waste handling areas are governed by Building and Fire Codes, and by <br />current local agency ordinances and zoning requirements. The design criteria described in this <br />fact sheet are meant to enhance and be consistent with these code and ordinance requirements. <br />Hazardous waste should be handled in accordance with legal requirements established in Title <br />22, California Code of Regulation. <br />Wastes from commercial and industrial sites are typically hauled by either public or commercial <br />carriers that may have design or access requirements for waste storage areas. The design <br />criteria in this fact sheet are recommendations and are not intended to be in conflict with <br />requirements established by the waste hauler. The waste hauler should be contacted prior to the <br />design of your site trash collection areas. Conflicts or issues should be discussed with the local <br />agency. <br />Designing New Installations <br />Trash storage areas should be designed to consider the following structural or treatment control <br />BMPs: <br />■ Design trash container areas so that drainage from adjoining <br />roofs and pavement is diverted around the area(s) to avoid <br />run-on. This might include berming or grading the waste <br />handling area to prevent run-on of stormwater. <br />■ Make sure trash container areas are screened or walled to <br />prevent off -site transport of trash. <br />CALFORn1A5 ORNv ATER <br />_ .I Ili i, I'.l li <br />January 2003 California Stormwater BMP Handbook 1 of 2 <br />New Development and Redevelopment <br />www.cabmphandbooks.com <br />
