Storm water pollution is a serious problem for wildlife dependent on our waterways and for the people who live near polluted streams or baylands. This pollution includes: spilled oil, fuel, and fluids from vehicles and heavy equipment; construction debris; landscaping runoff containing pesticides or weed killers; and materials such as used motor oil, antifreeze and paint products that people pour or spill into a street or storm drain. Chemicals are the number one water pollutant. Eighteen cities, the County, and the County Flood Control District have joined together to educate local residents and businesses to fight storm drain pollution. We hope you will join us by using the practices described in this pamphlet. Who should use this Brochure? Road crews Driveway/sidewalk/parking lot construction crews Seal coat contractors Operators of: grading equipment, paving machines, dump trucks, concrete mixers Construction inspectors General Contractors Developers Storm Drain Pollution from Roadwork Road paving, surfacing, and pavement removal happen right in the street, where there are numerous opportunities for storm drain contamination by asphalt, saw-cut slurry, or excavated material. Extra planning is required to store and dispose of materials properly and guard against pollution of the storm drains and creeks. What Can You Do? General Business Practices Develop and implement erosion/sedi- ment control plans for embankment. Schedule excavation and grading work for dry weather. Check for and repair leaking equipment. Perform major equipment repairs in designated areas at your yard, away from the construction site. When refueling or vehicle/equipment maintenance must be done on site, designate a location away from storm drains and creeks. Do not use diesel oil to lubricate equipment or parts. Recycle used oil, concrete, broken asphalt, etc., whenever possible. During Construction Avoid paving and seal coating in wet weather, or when rain is forecast before fresh pavement will have time to cure. Cover and seal catch basins and manholes when applying seal coat, slurry seal, fog seal, etc. Use check dams, ditches or berms to divert runoff around excavations. Never wash excess material from exposed aggregate concrete or similar treatments into a street or storm drain. Collect and recycle, or dispose to dirt area. Cover stockpiles (asphalt, sand, etc.) and other materials with plastic tarps. Protect from rainfall and prevent runoff with temporary roofs or plastic sheets and berms. Catch drips from paver with drip pans or absorbent material (cloth, rags, etc.) placed under machine when not in use. Clean up all spills and leaks using "dry" methods (with absorbent materials and/or rags), or dig up and remove contaminated soil. Collect and recycle or appropriately dispose of excess abrasive gravel or sand. Avoid over-application by water trucks for dust control. Asphalt/Concrete Removal Avoid creating excess dust when breaking asphalt or concrete. After breaking old pavement, be sure to remove all chunks and pieces. Make sure broken pavement does not come in contact with rainfall or runoff. Shovel or vacuum saw-cut slurry and remove from site. Cover or barricade storm drain during saw-cutting if necessary. Never hose down streets to clean up tracked dirt.
