Dear Mr. Hawkins:

On September 22, 2008, the U.S. Environmental Protection Agency (EPA)
received a revision to the District of Columbia’s State Implementation
Plan (SIP) from the District Department of the Environment (DDOE).  This
revision consists of Certification of Reasonably Available Control
Technology (RACT) State Implementation Plan under the 8-hour ozone
national ambient air quality standard (NAAQS).  EPA has determined that
the submittals are administratively and technically complete, and is
reviewing them to prepare a Notice of Proposed Rulemaking.  

If members of your staff have any questions, they may direct them to
Patrick Egan at (215) 814-3167.  He is the principal contact for this
rulemaking.    

	Sincerely, 

	

                                                                        
 /s/

         Judith M. Katz, Director
