Storm Water Quality


The automotive repair and maintenance industry works with hazardous chemicals and fluids that have the potential to contaminate our storm water, streams and ocean. When it rains, storm water can pick up and wash these pollutants into the City’s storm drain system which flows directly into our streams and coastal waters. The City has developed guidance and resources for the automotive industry to help them implement Best Management Practices (BMPs) to keep our island waters clean.

Clean It Right to prevent storm water pollution!

The Clean It Right Program highlights automotive businesses that have taken the pledge to make good housekeeping a priority and use best management practices to maintain their shops by:

  1. Cleaning up all drips and spills immediately;
  2. Using absorbent materials and other dry methods of cleaning; and,
  3. Never hosing out the shop area to the street or storm drain.
