The use of Best Management Practices (BMPs) will help to reduce pollution in our local creeks and waterways. This section provides guidance materials on BMPs relevant to most businesses. If you cannot find BMPs for a particular activity associated with your business, please email the Napa Countywide Stormwater Pollution Prevention Program (NCSPPP) Program Manager for assistance.
Go to the California Stormwater Quality Association (CASQA) website for more information on BMPs related to industrial and commercial activities.
