The U.S. Environmental Protection Agency (EPA) is announcing a funding opportunity (EPA-OAR-IO-25-01) for applications to support the operations of the National Tribal Air Association (NTAA). With a total funding amount of $1,675,000 over five years, this initiative aims to enhance Tribal air quality management by providing expert regulatory analysis and policy coordination for Federally recognized Tribes and Alaska Native Villages. Eligible applicants include states, local governments, Indian Tribes, and non-profit organizations, with a submission deadline set for October 1, 2025. The proposal emphasizes collaboration between the NTAA Executive Committee, member Tribes, and the EPA to facilitate Tribal participation in air quality planning and implementation activities. Key tasks involve ongoing administrative support, expert analysis of EPA policies, communication efforts, and organizing an annual conference to foster relationships and share knowledge among Tribes. Applicants must demonstrate their project’s significance, expected outputs and outcomes, and their organizational capability, including past performance and expertise. The evaluation process will consider the completeness of applications and adherence to submission guidelines while ensuring fair competition for funding based on the proposals' merits.
