Approval and Promulgation of Implementation Plans; Minnesota

الملخص

USEPA is proposing to approve a revision to the Minnesota State Implementation Plan (SIP) for new source review in nonattainment areas, submitted to meet longstanding requirements as well as new requirements imposed by the Clean Air Act Amendments of 1990. This revision consists of the State Rules 7005.3010 through 7005.3060, which incorporate by reference the new source review requirements specified in appendix S to title 40 Code of Federal Regulations part 51 (40 CFR part 51), ``Emission Offset Interpretive Ruling,'' except for the deletion of unacceptable exemptions included in appendix S. Final approval of this revision would lift the current ban on permitting major sources and major modifications in Minnesota nonattainment areas.
