Approval and Promulgation of Implementation Plans; Oklahoma; Revisions to Minor New Source Review Permitting Program

The Environmental Protection Agency (EPA) is proposing to approve severable portions of revisions to the Oklahoma New Source Review (NSR) State Implementation Plan (SIP) submitted by the State of Oklahoma on February 14, 2002 (the February 14, 2002, SIP submittal). This action addresses revisions to the Oklahoma Administrative Code (OAC), Title 252, Chapters 4 and 100, concerning the State's Minor New Source Review air permitting program. Many revisions are administrative in nature and modify redundant or incorrect text within the SIP. The revisions also include renumbered or codified portions of the SIP and new sections that incorporate Federal rules. This rulemaking is being taken in accordance with section 110 of the Clean Air Act (CAA).
