Countywide Stormwater Pollution Prevention Program

Foam Pollution (Stormwater)

Development

Stormwater runoff from homes, businesses and public facilities can be a significant source of pollution to the nation's waters, including our creeks and the Napa River. In 1987 Congress began to address this problem by requiring cities and counties to obtain National Pollutant Discharge Elimination System (NPDES) permits. The NPDES permits require cities and counties to develop and implement programs to control the discharge of pollutants both during construction and after the development is completed.  The General Construction Permit, effective July 1, 2010, establishes regulations for construction projects larger than one acre.  The Industrial General Permit was developed for industrial facilities (including wineries).
