Dear Mr. Sydnor:

On October 3, 2006, the United States Environmental Protection Agency
(EPA) received a revision to the Virginia State Implementation Plan
(SIP) from the Department of Environmental Quality pertaining to the
September 28, 2006, submittal of amendments to Virginia’s non-CTG NOx
RACT regulations (Regulation revision A99).  The 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
Christopher Cripps, Air Quality Planning Branch, at (215) 814-2179.  He
is the principal contact for this rulemaking.    

Sincerely, 

	/s/

   	Judith M. Katz, Director
