 Wind River Tribes' application for "Treatment in a Similar Manner as a State" under the Clean Air Act

The Northern Arapaho and Eastern Shoshone Tribes of the Wind River Indian Reservation (Tribes) have applied to EPA Region 8 for Treatment in a Similar Manner as a State (TAS) pursuant to Clean Air Act (CAA) Section 301(d) and EPA regulations at 40 CFR Part 49. Specifically, the Tribes' CAA TAS application requests that EPA find that the Tribes are eligible to administer grants under CAA Section 105; to be treated as an "affected state" under CAA Section 505(a)(2); for approval for CAA provisions for which no separate Tribal program is required, including Sections 107(d)(3), 112(r)(7)(B)(iii), 126, 169B, 176A, and 184; and for a determination by EPA that the Tribes meet the eligibility requirements of 40 C.F.R. § 49.6.

The Tribes' CAA TAS application describes the Reservation boundary as: areas described in the 1868 Treaty of Fort Bridger, less those areas conveyed by the Tribes under the Lander and Thermopolis Purchase Acts, plus lands subsequently added to the Reservation under the Act of June 27, 1940, 54 Stat. 628.

Below, please find a copy of the public notice, plus relevant portions of the Tribes' application: the Tribes' description of the Reservation boundaries; the reference map; and their Statement of Legal Counsel.
