§ 60.27a Actions by the Administrator.

(a) The Administrator may, whenever he determines necessary, amend the period for submission of any plan or plan revision or portion thereof.

(b) After determination that a plan or plan revision is complete per the requirements of § 60.27a(g), the Administrator will take action on the plan or revision. The Administrator will, within twelve months of finding that a plan or plan revision is complete, approve or disapprove such plan or revision or each portion thereof.

(1) Full and partial approval and disapproval. In the case of any plan or plan revision on which the Administrator is required to act under this paragraph (b), the Administrator shall approve such plan or plan revision as a whole if it meets all of the applicable requirements of this subpart. If a portion of the plan or plan revision meets all the applicable requirements of this subpart, the Administrator may approve the plan or plan revision in part and disapprove in part. The plan or plan revision shall not be treated as meeting the requirements of this chapter until the Administrator approves the entire plan or revision as complying with the applicable requirements of this subpart.

(2) Conditional approval. The Administrator may approve a plan or plan revision based on a commitment of the State to adopt and submit to the Administrator specific enforceable measures by a date certain, but not later than twelve months after the date of conditional approval of the plan or plan revision. Any such conditional approval shall be treated as a disapproval if the State fails to comply with such commitment.

(c) The Administrator will promulgate, through notice-and-comment rulemaking, a Federal plan, or portion thereof, at any time within twelve months after:

(1) The State fails to submit a plan or plan revision within the time prescribed or the State has failed to satisfy the minimum criteria under paragraph (g) of this section as of the time prescribed in paragraph (g)(1) of this section; or

(2) The Administrator disapproves the required State plan or plan revision or any portion thereof, as unsatisfactory because the applicable requirements of this subpart or an applicable emission guideline under this part have not been met.

(d) The Administrator will promulgate a final Federal plan, or portion thereof, as described in paragraph (c) of this section unless the State corrects the deficiency, and the Administrator approves the plan or plan revision, before the Administrator promulgates such Federal plan.
