Under this section, a State may seek approval of a State program to be implemented and enforced in lieu of specified existing or future Federal emission standards or requirements promulgated under section 112. A State may not seek approval under this section for a program that implements and enforces part 68 requirements.

At its discretion, the State may include in this submittal a request for approval of specific alternative requirements under paragraph (b)(3) of this section.
(2) [Reserved]
(3) The Administrator will require that comments be submitted concurrently to the State.
(4) If, after review of all public comments and State responses to comments submitted to the Administrator, the Administrator finds that the criteria of paragraph (b) of this section and the criteria of § 63.91 are met, the Administrator will approve or partially approve the State program. The approved State program will be published in the Federal Register and incorporated, directly or by reference, in the appropriate subpart of part 63.
(5) If the Administrator finds that any of the criteria of paragraph (b) of this section or § 63.91 have not been met, the Administrator will partially approve or disapprove the State program.

(i) Within 90 days after receipt of a complete request for approval of a State program submitted under paragraph (b)(1) or (b)(2) of this section; or
(ii) Within 180 days after receipt of a complete request for approval of a State program submitted under paragraphs (b)(1) or (b)(2) and paragraph (b)(3) of this section.
(b) Criteria for up-front approval. Any request for program approval under this section shall meet all of the criteria of this paragraph and § 63.91 before approval.
