Clean Air Act Promulgation of Extension of Attainment Date for the San Diego, California Serious Ozone Nonattainment Area

Riepilogo

EPA is extending the attainment date for the San Diego serious ozone nonattainment area from November 15, 1999, to November 15, 2000. This extension is based in part on monitored air quality readings for the 1-hour national ambient air quality standard (NAAQS) for ozone during 1999. Accordingly, we are updating the table concerning attainment dates for the State of California. In this action, we are approving the State's request through a "direct final" rulemaking. Elsewhere in this Federal Register, we are proposing approval and soliciting written comment on this action; if adverse written comments are received, we will withdraw the direct final rule and address the comments received in a new final rule; otherwise no further rulemaking will occur on this attainment date extension request.
