## Abstract

The purpose of this action is to announce the EPA's resolution of an intergovernmental dispute over a request by the Yavapai-Apache Tribal Council to redesignate the Yavapai-Apache Reservation (``the Reservation'') as a non-Federal Class I area under the Clean Air Act program for prevention of significant deterioration of air quality. On August 22, 1994 the Governor of Arizona raised concerns about EPA's proposal to approve the request of the Yavapai-Apache Tribe to redesignate its Reservation as a Class I area and asked EPA to initiate the intergovernmental dispute resolution process provided for in section 164(e) of the Clean Air Act. The State and the Tribe were unable to reach an agreement concerning the redesignation. Section 164(e) of the Clean Air Act provides that EPA must therefore resolve the dispute. After fully considering the concerns raised by the State of Arizona, EPA declines in these particular circumstances to disapprove the Tribe's decision to limit the amount of air quality deterioration allowed within its Reservation. Therefore, as described in a final rulemaking notice also published in today's Federal Register, EPA is finalizing its proposed decision to redesignate the Yavapai-Apache Reservation as a non-Federal Class I area. The Class I designation will result in lowering the allowable increases in ambient concentrations of particulate matter, sulfur dioxide, and nitrogen dioxide within the Reservation.
