Finding of Substantial Inadequacy of Implementation Plan; Call 
for Utah State Implementation Plan Revision

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 November 19, 2010 (75 FR 70888). In the November 19, 2010 document, 
EPA proposed a finding that the Utah State Implementation Plan (SIP) is 
substantially inadequate to attain or maintain the national ambient air 
quality standards (NAAQS) or to otherwise comply with the requirements 
of the Clean Air Act (CAA), based on Utah's rule R307-107, which 
exempts emissions during unavoidable breakdowns from compliance with 
emission limitations. At the request of several commentors, EPA is 
extending the comment period through January 3, 2011.

DATES: Comments must be received on or before January 3, 2011.
