California's Nonpoint Source (NPS) Pollution Control Program provides a coordinated statewide approach to addressing NPS pollution. This program addresses federal requirements to manage polution runoff under both the Clean Water Act and the Coastal Zone Management Act, by implementing California’s Coastal Nonpoint Pollution Control Program on a statewide basis.

The Coastal Nonpoint Pollution Control Program, established in 1990 by the Coastal Zone Act Reauthorization Amendments, is jointly administered by the National Oceanic and Atmospheric Administration and the U.S. Environmental Protection Agency. The program’s goal is to reduce polluted runoff to coastal waters.

The State Water Resources Control Board and the California Coastal Commission are the lead agencies for implementing California's NPS Program, in partnership with the nine Regional Water Quality Control Boards. There are 28 state agencies working collaboratively through the statewide Interagency Coordinating Committee (IACC) to implement the California NPS Program Implementation Plan.
