Dear Ms. Epps:

On June 28, 2012, the U.S. Environmental Protection Agency (EPA)
received a revision to the Allegheny County portion of the Pennsylvania
State Implementation Plan (SIP) from the Pennsylvania Department of
Environmental Protection.  The SIP revision pertains to the Control of
NOx emissions from glass melting furnaces.  EPA has determined that the
submittal is administratively and technically complete, and is reviewing
it to prepare a Notice of Proposed Rulemaking.  

If members of your staff have any questions, they may direct them to Ms.
Jacqueline Lewis, at (215) 814-2037.  She is the principal contact for
this rulemaking.    

Sincerely,

	

                                                                        
  

	               /s/

          David Arnold, Acting Director
