Nonpoint Source 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.

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 or practices identified in a DEQ-accepted Watershed Restoration Plan, an EPA-approved Tribal Nonpoint Source plan, or the current Montana Nonpoint Source Management Plan.
• 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.)
• On-The-Ground projects must 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.

Additional minimum standards and requirements are included in the Call for Applications.

The following activities are NOT eligible for funding: 

• Development of a Watershed Restoration Plan, exception made for Capacity Building projects.
• Activities required as a condition of a point source (MPDES) discharge permit.
• 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.
• Statewide education and outreach campaigns.

Additional information is included in the Call for Applications.

The 2025 Call for Applications closed on March 28, 2025.

Funding Overview

Funding Sources:

United States Environmental Protection Agency (EPA) Section 319(h) of the Federal Clean Water Act. 

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

Funding Distribution: 

• $500K to On-The-Ground projects located within the Lower Gallatin and Shields Focus Watersheds. (Lower Gallatin is a DEQ Nonpoint Source Focus watershed; Shields is an NRCS National Water Quality Initiative watershed)
• $500K (plus any unallocated funds from the Focus Watersheds) to On-The-Ground projects elsewhere in Montana, and to Capacity Building / Education and Outreach projects. 

Project Types:

On-the-Ground Projects:
Recommended Range for Funding Requests: $10,000-$300,000
Application Form: On-the-Ground Projects

Capacity Building / Education and Outreach Projects:
Recommended Range for Funding Requests: $10,000-$30,000
Application Form: Capacity Building / Education and Outreach Projects

Match Requirements

A 40 percent match (cost share) 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 minimum amount of non-federal match for your project: ((319 dollars requested)/.60) – (grant funding requested) = 40% required non-federal match.

Timeline: Two-Phase Solicitation Schedule

A 2026 Call for Applications is expected to open in late 2025 or early 2026. Check back for updated information.  

The Lower Shields River Watershed has been selected as the next Focus Watershed. 

A focus watershed is a HUC10 watershed area where the goal is to increase the capacity of local organizations, raise public awareness, and build momentum to generate significant and measurable progress toward reducing nonpoint source pollution.

The Lower Shields River Watershed will be eligible for approximately $500k annually of Federal Clean Water Act §319 grant funding for three funding cycles (in 2026, 2027 and 2028) and additional technical assistance from DEQ staff.

Focus Watershed applications were accepted until January 3, 2025.

Montana DEQ encourages the development of locally-led Watershed Restoration Plans (WRPs) as a means of charting a path to improved water quality. All 319-funded projects must implement practices identified in a DEQ-accepted Watershed Restoration Plan or acceptable alternative.

Nine Minimum Elements

Each Watershed Restoration Plan must address nine minimum elements.

• Identification of causes of impairment and sources of pollution.
• An estimate of the pollutant load reductions needed to achieve water quality standard
• A description of the nonpoint source management measures needed to achieve pollutant load reductions.
• An estimate of the technical and financial assistance needed to implement the management measures.
• An education and outreach component to encourage public participation in designing and implementing the management measures.
• A reasonable schedule for implementing the management measures.
• Milestones to gauge progress in implementing the management measures.
• Criteria for determining to what extent management measures are reducing pollutant loads and improving water quality over time.
• A monitoring plan for collecting the data necessary to evaluate improvements based on the criteria above.

Planning Tools and Guidance

The Environmental Protection Agency and other entities have developed tools to guide watershed restoration plan development.

• Handbook for Developing Watershed Plans to Restore and Protect Our Waters (EPA) - An extensive guide to watershed restoration planning.
