Nonpoint Source Program (NPS)
NPS Program Overview
The Porter-Cologne Water Quality Control Act (Porter-Cologne Act) was amended in 1999 to require the State Water Resource Control Board (SWRCB) to develop guidance to enforce the state’s Non-Point Source (NPS) pollution control program. Compliance was attained by adopting the NPS Implementation and Enforcement Policy on May 20, 2004. Every five years the State Board, nine Regional Boards, and California Coastal Commission put together the NPS Implementation plan. The goal of this five-year plan is to present, in one place, the general goals and objectives of the co-lead agencies for addressing NPS pollution over the timeframe of January 2021 to June 2025.
The NPS program also administers grant money through section 319(h) of the Federal Clean Water Act. This funding can be used to implement projects that reduce NPS pollution. For more information on grants and funding please visit the 319(h) grant program website below.
The Region's NPS Program implements the statewide Nonpoint Source Pollution Implementation Plan, and is consistent with the statewide Policy for Implementation and Enforcement of the Nonpoint Source Pollution Control Program.
