Last Updated:



The Clean Water Act Section 319 Grant Program awards grants to reduce and mitigate the effects of nonpoint  source pollution - such as sediment, pesticides, and nutrients - to waters of the state. 


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-0imparied waters, habitat restoration such as installation of large woody debris and riparian revegetation, and rural road inventories and repairs to reduce sedimentation and erosion. Most awards go to projects that improve impaired waters, but a small amount of funding goes to projects that protect high-quality waters, or that address a nonpoint source pollution problem created by a wildfire.
