Clean Air Act Promulgation of Extension of Attainment Date for Ozone Nonattainment Area; Ohio; Kentucky

EPA is extending the attainment date for the Cincinnati- Hamilton interstate moderate ozone nonattainment area from November 15, 1997 to November 15, 1998. This extension is based in part on monitored air quality readings for the national ambient air quality standard (NAAQS) for ozone during 1997. Accordingly, EPA is revising the table in the Code of Federal Regulations concerning ozone attainment dates in this area. In this action, EPA is approving the States' request through ``direct final'' rulemaking; the rationale for this approval is set forth below. Elsewhere in this Federal Register, EPA is proposing approval and soliciting comment on this action; should EPA receive such comment, it will publish an action informing the public that this rule did not take effect; otherwise no further rulemaking will occur on this SIP revision request.
