The requirements of 40 CFR Part 93 to demonstrate conformity required under § 176(c) of the federal Clean Air Act apply to all federal actions in designated nonattainment and maintenance areas where EPA has not approved this regulation. When EPA approves this regulation in a revision to the Commonwealth of Virginia applicable implementation plan, a conformity evaluation is governed by the approved or approved portion of this regulation. The regulations contained in 40 CFR Part 93 apply only for the portions, if any, of the 40 CFR Part 93 requirements not contained in the provisions of this regulation approved by EPA. In addition, any previously applicable implementation plan requirements shall remain enforceable until EPA approves the revision to the Commonwealth of Virginia's applicable implementation plan to specifically include the revised requirements or remove requirements.
