As mandated by state requirements, the City is required to implement a Stormwater and Pollution Discharge Control Program, which includes business inspections.  The City protects the local creeks, wetlands, and Napa River by enforcing businesses to comply with the storm water program requirements and to follow Best Management Practices (BMPs). Discharging substances other than rain water to a storm drain is prohibited by the City’s Municipal Code, as well as by State and Federal laws. Violators may be subject to penalties and the cost of cleanup.       

 

The following are pollutants that degrade the quality of local waters, harm aquatic life, and potentially increase the population of pests. If allowed to run out on sidewalks, gutters and streets they flow untreated to our creeks and wetlands, and eventually to the Napa River. 

  • Detergents & cleansers
  • Food waste
  • Wine waste
  • Grease
  • Oil
  • Liquids leaking from dumpsters
  • Mop water
  • Pressure washer water

The City supports businesses in meeting Stormwater and Pollution Discharge Control Program requirements through outreach.  If you would like an Environmental Specialist to visit your business to discuss how you can meet the requirements, please call (707) 647-4521 or email us.
