Dear Ms. Epps:

On January 9, 2008, the U.S. Environmental Protection Agency (EPA)
received a revision to the Pennsylvania State Implementation Plan (SIP)
from the Pennsylvania Department of Environmental Protection (PADEP).
This revision is requesting the approval of the Columbia County,
Pennsylvania’s 110(a)(1) 8-Hour Ozone Maintenance Plan and Base-Year
Inventory.   The EPA has determined that the submittal is
administratively and technically complete, and is reviewing it to
prepare a Notice of Proposed Rulemaking (NPR).  

If members of your staff have any questions, they may direct them to
Gregory Becoat, Air Quality Planning Branch, at (215) 814-2136.  He is
the principal contact for this rulemaking.    

	Sincerely, 

 

/s/
