Dear Mr. Paylor:

On February 24, 2009, U.S. Environmental Protection Agency (EPA)
received a revision to the Commonwealth of Virginia’s State
Implementation Plan (SIP) from the Department of Environmental
Protection pertaining to the opacity variance for a rocket testing
facility located in Orange County.  EPA has determined that the
submittal is administratively and technically complete, and is reviewing
it to prepare a Notice of Proposed Rulemaking/Final Rulemaking Notice.  

If members of your staff have any questions, they may direct them to Mr.
Timothy Leon-Guerrero, Air-Quality Analysis Branch at (215) 814-2192. 
Mr. Leon Guerrero is the principal contact for this rulemaking.    

	Sincerely, 

                                                                        
  /s/
