Roadwork & Paving

Roadwork & Paving Problems
Road paving, surfacing and pavement removal activities contribute to urban runoff pollution because they take place right in the street, where urban runoff contamination can result from asphalt, saw-cut slurry or excavated material.

Rain or runoff can carry these toxic substances to the ocean through the storm drain system, posing a hazard to human and sea life.

Extra planning is required to store and dispose of materials properly and guard against storm water and ocean pollution. This brochure tells you how.

Solutions

General Business Practices

  • Schedule excavation and grading work for dry weather.

  • Keep materials out of the rain. Store them under cover, with temporary roofs or plastic sheets, protected from rainfall, runoff and the wind.

  • Develop and implement erosion and sediment control plans for embankments.

  • Recycle used oil, concrete, broken asphalt, etc.

Equipment Maintenance

  • Maintain all vehicles and heavy equipment. Inspect frequently for leaks.

  • Conduct all vehicle/equipment maintenance and refueling at one location - away from storm drains.

  • Perform major maintenance, repair jobs and vehicle/equipment washing off site.

  • Use gravel approaches where truck traffic is frequent to reduce soil compaction and limit the tracking of sediment into streets.

  • Use drip pans or drop cloths to catch drips and spills, if you drain and replace motor oil, radiator coolant or other fluids on site. Collect all used fluids, store in separate containers and recycle whenever possible.

  • Do not use diesel oil to lubricate equipment or parts.

Asphalt & Concrete Removal

  • When breaking up paving (cement or asphalt), be sure to pick up all the pieces. Recycle them at a crushing company.

  • Dispose of small amounts of excess dry concrete, grout and mortar in the trash

  • Never bury waste material. Recycle or dispose of it as hazardous waste material. Contact Hazardous Waste Hotline at (800) 552-5218.

  • Make sure broken pavement does not come in contact with rainfall or runoff.

  • Shovel or vacuum saw-cut slurry and remove from the site. For disposal information, call the Los Angeles County Household Hazardous Waste Hotline at (800) 522-5218.

  • Cover or barricade storm drain openings during saw-cutting

Disposal Options

  • Use a crushing company like those listed below to recycle cement, asphalt and porcelain rather than taking them to a landfill.

During Construction

  • Cover catch basins and maintenance holes when applying seal coat, slurry seal, fog seal, etc.

  • Use check dams, ditches or berms to divert runoff around excavations.

  • Never wash excess materials from exposed aggregate concrete or similar treatments into a street, gutter or storm drain. Collect and recycle, or dispose to a dirt area.

  • Collect and recycle excess abrasive gravel or sand.

  • Avoid over-application by water trucks for dust control

Spills

  • Never hose down "dirty" pavement or surfaces. Clean up all spills and leaks using "dry" methods (with absorbent materials and/or rags), or dig up and remove contaminated soil. For disposal information, call the Los Angeles County Hazardous Household Waste Hotline at (800) 552-5218.

  • Catch drips from paver with drip pans or absorbent material (cloth, rags, etc.) placed under machine when not in use.
