About this program

The Environmental Protection Agency is funding implementation of EPA-approved nonpoint source management programs under Clean Water Act Section 319 through formula grants to States, tribes, and intertribal consortia, with the most recent award to Idaho on January 1, 2026, under Assistance Listing 66.460.

The program has sustained activity across three decades, with 2,154 total awards since 1993 and an average of 47–54 awards per year over the past five years. The portfolio totals $3.61 billion in federal dollars obligated and $5.5 billion combined with non-federal cost-share. Grant awards support implementation of best management practices—including riparian restoration, stream stabilization, agricultural BMPs, erosion control, and green infrastructure—alongside watershed planning, monitoring, education, and outreach to reduce sediment, nutrient, bacterial, and thermal loading from diffuse pollution sources. Awards fund state and tribal programs to pass funding to subawardees for on-the-ground restoration and protection work.

Awards are predominantly Formula Grants, which represent 85 percent (1,823 awards), with smaller shares of Project Grants (14 percent) and Cooperative Agreements (2 percent). The Environmental Protection Agency accounts for the vast majority of funding, with its headquarters office obligating $2.64 billion across 1,703 awards. EPA regional offices—particularly Region 4 ($188.6 million), Region 5 ($174.5 million), Region 6 ($152.7 million), and Region 3 ($111 million)—distribute the remainder. Recent awards to California ($14.364 million), Florida ($10.551 million), Kansas ($9.425 million), Illinois ($12.230 million), and Ohio ($8.231 million) demonstrate multi-million-dollar federal investments typical of larger state programs.

Recent awards span state and tribal recipients. California received $14.364 million to implement coastal nonpoint source pollution control and watershed-based plans. Pennsylvania received $8.704 million for abandoned mine drainage remediation and agricultural BMPs. North Dakota received $6.490 million for nutrient reduction and farmer education in ten targeted watersheds. Tribal recipients—including Pueblo of Santa Clara, Ft. McDowell, Pawnee Nation, Iowa Tribe of Oklahoma, and Chemehuevi Indian Tribe—received smaller formula or base-grant awards ($50,000 to $268,169) for BMP implementation, water quality monitoring, and education.

A competitive grant opportunity for Indian Tribes and Intertribal Consortia (EPA-OW-OWOW-26-01) was posted August 17, 2026, with applications due November 9, 2026. It solicits on-the-ground BMP implementation projects and watershed planning under Clean Water Act Section 319, supporting federally recognized tribes and intertribal consortia with approved NPS management programs. Eligible applicants may use up to 25 percent of federal funds for nine-element watershed-based plan development; all projects must include on-the-ground BMP implementation.

Eligibility

Applicant eligibility

Eligible entities include States and qualified Indian Tribes and intertribal consortia who have approved nonpoint source assessment reports and management plans. To be qualified, Tribes must have treatment in a manner similar to a state (TAS) status for the 319 Program. Grants to States are awarded by formula. The State allotment is awarded to the agency in each State designated by the chief executive as the lead nonpoint source agency. The lead nonpoint source agency may distribute grant funds to other organizations in accordance with its work program, which is approved by EPA. Eligible Tribes are allocated a base allotment by formula; the remaining Tribal portion of the 319(h) appropriation is competed among qualified Indian Tribes and intertribal consortia. For certain competitive funding opportunities under this assistance listing, the Agency may limit eligibility to compete to a number or subset of eligible applicants consistent with the Agency's Assistance Agreement Competition Policy.

Beneficiary eligibility

State and local governments; interstate and intrastate agencies; federally recognized Indian tribal governments; intertribal consortia; the following US territory or possessions: the District of Columbia, American Samoa, Guam, Northern Marianas, Puerto Rico, Virgin Islands; public and private nonprofit organizations and institutions. The lead nonpoint source agency may distribute grant funds to other organizations in accordance with a work program which is approved by EPA.

Uses of assistance

Funds are provided to eligible applicants to carry out nonpoint source projects and programs pursuant to Section 319 of the Clean Water Act as amended by the Water Quality Act of 1987. Requirements under Section 319(h) include: nonfederal matching funds of at least 40 percent of project cost (match is an overall grant requirement - the match requirement for an individual project may be waived and in-kind services may be used as match); maintenance of effort; grants may be used for financial assistance to individual persons in the case of demonstration projects only; annual reporting; and EPA determinations of adequate recipient progress before additional funding. Assistance agreement awards under this program may involve or relate to geospatial information. Further information regarding geospatial information may be obtained by viewing the following website: Geospatial Resources at EPA. This program makes Federal awards on a discretionary basis. A discretionary award means an award in which the Federal awarding agency, in keeping with specific statutory authority that enables the agency to exercise judgement ("discretion"), selects the recipient and/or the amount of Federal funding awarded through a competitive process or based on merit of proposals. A discretionary award may be selected on a non-competitive basis, as appropriate. For further information, please contact the Headquarters or regional office.

Length and time phasing of assistance
