SC-44 Drainage System Maintenance <br />- OSHA Confined Space Entry training (Cal -OSHA Confined Space, Title 8 and Federal <br />OSHA 29 CFR 1910.146). <br />- Procedural training (field screening, sampling, smoke/dye testing, TV inspection). <br />Spill Response and Prevention <br />■ Investigate all reports of spills, leaks, and/or illegal dumping promptly. <br />■ Cleanup all spills and leaks using "dry" methods (with absorbent materials and/or rags) or <br />dig up, remove, and properly dispose of contaminated soil. <br />■ Refer to fact sheet SC-u Spill Prevention, Control, and Cleanup. <br />Other Considerations (Limitations and Regulations) <br />■ Clean-up activities may create a slight disturbance for local aquatic species. Access to items <br />and material on private property may be limited. Trade-offs may exist between channel <br />hydraulics and water quality/riparian habitat. If storm channels or basins are recognized as <br />wetlands, many activities, including maintenance, maybe subject to regulation and <br />permitting. <br />■ Storm drain flushing is most effective in small diameter pipes (36-inch diameter pipe or less, <br />depending on water supply and sediment collection capacity). Other considerations <br />associated with storm drain flushing may include the availability of a water source, finding a <br />downstream area to collect sediments, liquid/sediment disposal, and prohibition against <br />disposal of flushed effluent to sanitary sewer in some areas. <br />■ Regulations may include adoption of substantial penalties for illegal dumping and disposal. <br />■ Local municipal codes may include sections prohibiting discharge of soil, debris, refuse, <br />hazardous wastes, and other pollutants into the storm drain system. <br />Requirements <br />Costs <br />■ An aggressive catch basin cleaning program could require a significant capital and O&M <br />budget. <br />■ The elimination of illegal dumping is dependent on the availability, convenience, and cost of <br />alternative means of disposal. The primary cost is for staff time. Cost depends on how <br />aggressively a program is implemented. Other cost considerations for an illegal dumping <br />program include: <br />- Purchase and installation of signs. <br />- Rental of vehicle(s) to haul illegally -disposed items and material to landfills. <br />- Rental of heavy equipment to remove larger items (e.g., car bodies) from channels. <br />- Purchase of landfill space to dispose of illegally -dumped items and material. <br />4 of 6 California Stormwater BMP Handbook January 2003 <br />Industrial and Commercial <br />www.cabmphandbooks.com <br />
