Under Section 105 of the Clean Air Act, EPA awards financial support and encourages Tribes to partner with EPA to carry out Clean Air Act protections within reservations and Tribal communities. This announcement is for Clean Air Act implementation to be completed in federal FY2027 and FY2028. EPA encourages proposals for two-year work plans from current grant recipients with a strong record of grant performance. If a Tribe wants to request more than two years of funding, please talk to your Project Officer. All federally recognized Tribes and Tribal consortia in Region 10 are eligible to receive funding under this grant opportunity.

Section 106 of the Clean Water Act authorizes EPA to provide financial assistance to Tribes to establish and administer programs for the prevention, reduction, and elimination of water pollution. Under Section 319 of the Clean Water Act, EPA offers grants and technical assistance to support Tribal environmental programs in assessing and managing their nonpoint source pollution problems and threats. EPA is encouraging 4-year applications to support calendar year 2027 activities and beyond. These grants are available to eligible Tribes and Tribal Consortia throughout Region 10.
