Nonpoint Source Program

Program Overview

Nonpoint source pollution typically comes from diffuse sources, such as grazing, timber harvest, abandoned mine lands, irrigation, recreation, and septic systems. It includes a wide range of pollutants and conditions, including nutrients (nitrogen and phosphorus), heavy metals, sediment, loss of riparian habitat, streamflow alteration, and temperature changes. Montana’s goal is to provide a clean and healthy environment by protecting and restoring water quality from the harmful effects of nonpoint source pollution. We believe this can best be achieved through voluntary implementation of land, soil, and water conservation practices.

319 Project Funding

Through the 319 Project Program, DEQ provides approximately $1,000,000 each year to local watershed groups, conservation districts, educational institutions, and government entities to design and implement on-the-ground projects that reduce and prevent nonpoint source pollution. Increasingly, DEQ is focusing funding on projects that will restore natural processes (e.g., stream channel migration, floodplain connectivity, native riparian revegetation) and are likely to result in measurable improvements in water quality.

Fiscal Year 2023 Funding Breakdown

Funding Source: The United States Environmental Protection Agency (EPA) under Section 319(h) of the Federal Clean Water Act.

Total Funding Available: Approximately $1,000,000.

Individual Awards: Recommended: $10,000 to $250,000 per project.

Fiscal Year 2023 Funding Breakdown

Funding will be divided into 3 pots, with unused funds from the Focus Watershed and Mini-Grant pots to be redistributed into the General Projects pot.

General Projects
Estimated Total Amount Available: $400,000 + any unused funds from the other two pots.
Recommended Range for Funding Requests: $10,000-$250,000

Focus Watershed Projects
Estimated Total Amount Available: $500,000
Recommended Range for Funding Requests: $10,000-$250,000
Specific Eligibility Requirements: Projects located in the Lower Gallatin watershed.

Mini-Grant Programs
Estimated Total Amount Available: $100,000
Recommended Range for Funding Requests: $30,000-$60,000

Cost Share: A 40 percent cost share (match) is required. The match must be from non-federal sources (state, local, private), and may include in-kind donations of time and resources contributed to completion of the project. Use the following formula to calculate the amount of non-federal match required for your project: ((319 dollars requested)/.60) – (319 dollars requested) = required non-federal match


Applicant Eligibility:

Applicants must meet the following criteria:

  • Be a governmental entity or a nonprofit organization. A governmental entity is a local, state, or federal organization that has been established and authorized by law. Nonprofit organizations are identified as having a tax-exempt declaration of 501(c)(3) from the Internal Revenue Service.
  • Be registered with the Montana Secretary of State to do business in the state of Montana.
  • Have the necessary liability insurance, and be in compliance with the Workers Compensation Act.

Project Eligibility

Projects must meet the following minimum requirements:

  • Address nonpoint source pollution.
  • Implement actions consistent with recommendations in the current Montana Nonpoint Source Management Plan.
  • Implement activities or practices identified in a DEQ-accepted Watershed Restoration Plan
  • Address impairments identified on Montana’s 2020 List of Impaired Waters. In some instances, projects on streams that are not listed as impaired may be acceptable. These projects must reduce pollutant loading to an impaired, downstream receiving water OR protect existing uses from becoming impaired.
  • Be completable within three years. (Note: In some instances, sponsors may be encouraged to apply for funding for design and permitting, and then come back and apply for funding for actual construction in a subsequent year.)
  • Projects addressing stream flow through improved water use efficiency must include reasonable assurance that unused water will remain in the stream (e.g., through a change of use to instream flow, or a signed commitment from the water right holder).
  • Projects involving grazing management (e.g., riparian fencing, creation of riparian pastures) must include a grazing management plan as a task deliverable.
  • Projects involving riparian or wetland buffer creation must have a minimum buffer width of 35 feet, as measured from the water’s edge. If the buffer must be less than 35 feet in some places to accommodate bridges, water gaps or other infrastructure, the buffer should be made proportionately wider in other areas.

The following activities are NOT eligible for funding:

  • Development of a Watershed Restoration Plan (WRP).
  • Activities required as a condition of a point source (MPDES) discharge permit.
  • Watershed characterization studies.
  • Pollutant source identification.
  • Water quality monitoring, except for monitoring the effectiveness of a current, 319-funded project.
  • Statewide education and outreach campaigns.
  • Projects whose primary purpose is to protect infrastructure from natural stream channel migration.
  • Use of non-native plant species in restoration projects.
  • Rip-rap, except in instances where it is necessary to protect a new bridge or culvert designed to restore aquatic organism passage.
  • Projects designed to address violations of state and federal law (e.g., projects that stem from a 310 violation or an Army Corps violation).
  • Projects that result in a net loss of wetlands or wetland function.

Additional Resources

DEQ provides limited funding for education and outreach through our E&O Mini-Grants Program, administered by Soil and Water Conservation. We are also often available to provide group presentations on a wide range of watershed health topics. DEQ provides significant support to watershed groups through partnerships and joint projects with the Montana Watershed Coordination Council, Montana Association of Conservation Districts, and state and federal agency partners.
