Nonpoint Source Program

Staff Contact: Robert Ray (406) 444-5319

Goal:  Protect water quality from the harmful effects of nonpoint source pollution. Nonpoint source pollution includes all forms of pollution not regulated by a discharge permit under the Montana Pollutant Discharge Elimination System. It typically comes from diffuse sources (as opposed to a pipe or ditch). It’s broad enough to include substances like nitrogen, phosphorus, metals, and sediment, and also conditions like stream temperature and riparian habitat.

Method:  Provide local, state, and federal partners with access to the tools they need in order to make significant, measurable improvements in water quality within their home watersheds.

The state of Montana receives funding annually from the Environmental Protection Agency (EPA) through Section 319 of the Clean Water Act to distribute throughout the state to groups interested in implementing projects that help achieve this goal. See the map below of projects we have funded, and for more information, visit the Nonpoint Source 319 Funding page.
