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

Riepilogo

On May 27, 1997, USEPA extended the attainment date for the Cincinnati-Hamilton interstate, moderate ozone nonattainment area from November 15, 1996 to November 15, 1997 utilizing ``direct final rulemaking'' procedures. On July 28, 1997, USEPA withdrew the direct final rule due to the receipt of adverse comments. In this action USEPA is responding to public comments received in response to the proposed rule and announcing that it is extending the attainment date for the Cincinnati-Hamilton interstate moderate ozone nonattainment area from November 15, 1996 to November 15, 1997. This extension is based in part on monitored air quality readings for the national ambient air quality standard (NAAQS) for ozone during 1996. The USEPA is also revising the table in the Code of Federal Regulations concerning ozone attainment dates in this area.
