On May 14, 1997 USEPA published a direct final rule (62 FR 26396) approving, and an accompanying proposed rule (62 FR 26463) proposing to approve a revision submitted on July 9, 1996 and January 31, 1997, to the ozone maintenance plans for the Dayton-Springfield Area (Miami, Montgomery, Clark and Greene Counties), Toledo Area (Lucas and Wood Counties), Canton Area (Stark County), Ohio portion of the Youngstown-Warren-Sharon Area (Mahoning and Trumbell Counties), Columbus Area (Franklin, Delaware, and Licking Counties), Cleveland- Akron-Lorain Area (Ashtabula, Cuyahoga, Lake, Lorain, Medina, Summit, Portage, and Geauga Counties), Preble County, Jefferson County, Columbiana and Clinton Counties. The revision was based on a request from the State of Ohio to revise the federally approved maintenance plan for these areas to provide the State and the affected areas with greater flexibility in choosing the appropriate ozone contingency measures for each area in the event such a measure is needed. On June 13, 1997 (62 FR 32204) the USEPA delayed the effective date of this rule for 60 days to allow for a 60-day extension of the public comment period. In the proposed rules section of the June 13, 1997 Federal Register (62 FR 32257), USEPA announced a 60-day extension of the public comment period on these maintenance plans, until August 12, 1997. On August 12, 1997 (62 FR 43109), USEPA further delayed the effective date of the approval of these maintenance plans for an additional 120 days until January 9, 1998. In the proposed rules section of the August 12, 1997 Federal Register (62 FR 43140), USEPA extended the public comment period until December 10, 1997. The USEPA is withdrawing this final rule due to the adverse comments received on these actions. In a subsequent final rule, USEPA will summarize and respond to the comments received and take final rulemaking action on this requested Ohio SIP revision.
