Nonattainment Area

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule; extension of the comment period.

SUMMARY:

EPA is extending the comment period for a document published on December 1, 2009 (74 FR 62717). In the December 1, 2009 document, EPA proposed to disapprove the State of Utah's requests under the Clean Air Act to redesignate the Salt Lake County, Utah County, and Ogden City PM

10

nonattainment areas to attainment, and to approve some and disapprove other associated State Implementation Plan (SIP) revisions. The Governor of Utah submitted the redesignation requests and associated SIP revisions on September 2, 2005. EPA proposed to disapprove the redesignation requests because the areas do not meet all Clean Air Act requirements for redesignation. At the request of several commentors, EPA is extending the comment period through March 1, 2010.

DATES:

Comments must be received on or before March 1, 2010.
