Dear Secretary O’Mara:

On November 17, 2009, the U.S. Environmental Protection Agency (EPA)
received a revision to the Delaware State Implementation Plan (SIP) from
the Department of Natural Resources and Environmental Control.  The SIP
revision pertains to a plan entitled “Regulation No.1142 – Specific
Emission Control Requirements.”  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 Mr.
Gregory Becoat, at (215) 814-2036.  He is the principal contact for this
rulemaking.    

	Sincerely, 

	

                                                                        
  

                                                                        
     /s/

         David Arnold, Acting Director
