(b) The requirements of sections 160 through 165 of the Clean Air Act are not met for Indian reservations since the plan does not include approvable procedures for preventing significant deterioration of air quality on Indian reservations. Therefore, the provisions of § 52.21 except paragraph (a)(1) are hereby incorporated and made part of the applicable plan for Indian reservations in the State of Idaho. (c) The requirements of section 165 of the Clean Air Act are not met for sources subject to prevention of significant deterioration requirements prior to August 22, 1986, the effective date of EPA's approval of the rules cited in paragraph (a) of this section. Therefore, the provisions of § 52.21 except paragraph (a)(1) are hereby incorporated and made part of the applicable plan for sources subject to § 52.21 prior to August 22, 1986.
