On February 21, 1997 the Ohio Environmental Protection Agency (Ohio EPA) submitted a State Implementation Plan (SIP) revision request to USEPA under the Clean Air Act (CAA). This revision request contained a number of rules and rule paragraphs formerly contained in the Ohio Administrative Code (OAC) which had been incorporated in the Ohio SIP but which had been amended or removed from the OAC by the State. The State requested that these rules and rule paragraphs be removed from the Ohio SIP since they were no longer part of the OAC. In this action, USEPA is approving the State's SIP revision request through a ``direct final'' rulemaking; the rationale for this approval is set forth below. Elsewhere in this Federal Register, USEPA is proposing approval and soliciting comment on this direct final action; if appropriate comments are received, USEPA will withdraw the direct final rulemaking and address the comments received in a new final rule; otherwise, no further rulemaking will occur on this SIP revision request.
