Dear Mr. Mirzakhalili,:

On June 29, 2009, EPA received a revision to the Delaware State
Implementation Plan (SIP) from the Delaware Department of Natural
Resources and Environmental Control (DNREC) pertaining to administrative
and non-substantive changes to 36 Delaware SIP regulations. EPA has
determined that the submittal is administratively and technically
complete, and is reviewing it to prepare a Direct Final Rulemaking
Notice (DFRN).  

If members of your staff have any questions, they may direct them to
Harold A. Frankford, Office of Air Programs, at (215) 814-2108.  He is
the principal contact for this rulemaking action.    

	Sincerely, 

						    /s/

    Diana Esher, Acting Director
