Polluted Runoff: Nonpoint Source (NPS) Pollution

Current Tribal §319 Grant Information

Tribes are eligible to receive Clean Water Act Section 319 grant funding to implement EPA-approved NPS programs. As required under the Clean Water Act, tribes must be approved for treatment in a similar manner as a state (TAS) and have an EPA-approved NPS assessment report and NPS management program to receive §319 funds. Each year, a §319-eligible tribe may apply for a base §319 grant that support their NPS management program, and they are eligible to compete nationally for additional §319 funds (competitive §319 grants) to implement on-the-ground projects to restore and protect their waters. 

See below for current information on application deadlines, eligible tribes and additional guidance.

Base Grants

The EPA anticipates awarding section 319 base grants to eligible tribes in the amount of $30,000 or $50,000 of federal §319 funding (depending on land area) on a noncompetitive basis. For tribes with 640,000 acres (1,000 square miles) or more, the base allocation is $50,000; for tribes with 640,000 acres or less, the base allocation is $30,000. Section 319 base funds may be used for a range of activities that implement the tribe's approved NPS management program, including: hiring a program coordinator; conducting NPS education programs; providing training and authorized travel to attend training; updating the NPS management program; developing watershed-based plans; and implementing watershed-based plans and on-the-ground watershed projects.

See below for the current EPA Guidelines for Awarding Clean Water Act Section 319 Base Grants to Indian Tribes.

Proposed base 319 grant work plan deadlines vary by EPA Region. Please contact your EPA region for more details.

In addition to awarding section 319 base grants (described above), each year the EPA's National NPS Program solicits applications via a national competition from §319-eligible tribes and intertribal consortia to implement on-the-ground projects to manage NPS pollution. Competitive §319 grants may be used to develop and/or implement watershed-based plans and other on-the-ground projects that will result in significant steps towards solving NPS impairments on a watershed-wide basis. Tribal applicants may request up to $100,000 in federal §319 funds through this competition. In recent years, the EPA has awarded approximately $2.5 million/year in federal §319 funds under this solicition, depending on Agency funding levels.
