2026 Clean Water Act Section 319 Nonpoint Source Pollution Grant

The 2026 Clean Water Act Section 319 Nonpoint Source Pollution Grant Program supports projects to reduce and mitigate the effects of nonpoint source pollutants to waters of the state within priority watersheds identified by the Regional Water Quality Control Boards. The program primarily funds implementation projects but occasionally offers grants for planning projects. Examples of projects include livestock fencing to reduce sediment and nutrient discharges, agricultural best management practices to reduce pesticide and nutrient discharges, dredging contaminated sediment from pesticide-impaired waters, habitat restoration such as installation of large woody debris and riparian revegetation, and rural road inventories and repairs to reduce sedimentation and erosion. • Eligible applicants include nonprofit organizations, public agencies, and tribal governments. • Eligible projects must address a program preference, which is a specific watershed or waterbody and pollutant combination identified by the Regional Water Quality Control Board. • The program requires a 25% match of the grant award amount. • The grant program is funded by the United States Environmental Protection Agency (U.S. EPA) under Clean Water Act (CWA) section 319.
