Mr. Tundermann: 

We are in receipt of the Utah Industry Environmental Coalition's (UIENC) request that EPA extend the 

public comment period on the proposed rule published in the Federal Register on December 1, 2009 

related to Utah PM 10 submittals. 

We received a number of requests to extend the comment period. 

We intend to publish a notice in the Federal Register by the end of this year to extend the comment period 

until March 1,2010. 

Thank you.

Re: Docket ID No. EPA-R08-0AR-2006-0013 

Dear Ms. Videtich: 

This letter is a request for an extension of the comment period on EPA's proposed 

disapproval of Utah's request to (a) redesignate the Salt Lake County, Utah County and 

Ogden City PM10 nonattainment areas to attainment and (b) approve certain State 

Implementation Plan (SIP) and Maintenance Plan provisions for those areas. 74 Fed. Reg. 

62717 (Dec. I, 2009). The Utah Industry Environmental Coalition ("UIENC") requests an 

extension of the comment period until March 31, 2010. 

UIENC is a group of Utah manufacturing and utility companies some of whose 

members are directly affected by Utah's PMlO SIP provisions and EPA's proposed 

disapprovals of Utah's redesignation requests and SIP and maintenance plans. UIENC's 

members include companies in the mining and mineral processing, steel, aerospace, pipe 

manufacture and natural gas industries. The proposed EPA disapprovals raise numerous 

legally and technically complex issues which cannot possibly be adequately addressed in 

the current thirty day comment period. Further, since years have passed since Utah 

submitted its requests, large files of data and analysis must be located and institutional 

memories refreshed to enable interested parties to comment knowledgably. Compounding 

the commenting task is that the comment period overlaps the holiday season. 

Accordingly, UIENC respectfully requests that the comment period for this 

proposed action be extended until March 31, 2010.
