Dear Ms. Epps:

On July 5, 2007, the U.S. Environmental Protection Agency (EPA) received
a revision to the Pennsylvania State Implementation Plan (SIP) from the
Department of Environmental Protection dated June 26, 2007.  This SIP
revision pertains to redesignation of the Allentown-Bethlehem-Easton
8-hour ozone nonattainment area to attainment, as well as the
Allentown-Bethlehem-Easton area maintenance plan and 2002 base-year
inventory.  The EPA has determined that the SIP submittal is
administratively and technically complete, and is reviewing this SIP
revision to prepare a Notice of Proposed Rulemaking.  

If members of your staff have any questions, they may direct them to
Brian Rehn, Air Quality Planning Branch, at (215) 814-2176.  He is the
principal contact for this rulemaking.    

Sincerely, 

	/s/

   	Judith M. Katz, Director
