Determination of Attainment for the Carbon Monoxide National Ambient Air Quality Standard for Metropolitan Provo; State of Utah, and Approval of Revisions to the Oxygenated Gasoline Program

Riepilogo

This proposed rule would make a determination of attainment for the carbon monoxide (CO) National Ambient Air Quality Standard (NAAQS) for the metropolitan Provo CO nonattainment area (hereafter Provo area) which was classified as "moderate". The Provo area was required by the Clean Air Act Amendments of 1990 to attain the CO NAAQS by December 31, 1995. This determination would be based on complete, quality assured ambient air quality monitoring data for the years 1994 and 1995. In addition, on September 27, 2001, the Governor submitted revisions to Utah's rule R307-301 "Utah and Weber Counties: Oxygenated Gasoline Program". EPA is also proposing approval of the revisions to rule R307-301. In the Final Rules Section of this Federal Register, EPA is approving the determination of attainment for the CO NAAQS for the Provo CO nonattainment area and the revisions to R307-301 as a direct final rule without prior proposal because the Agency views this action as noncontroversial and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this proposed rule, no further activity is conte
