Dear Secretary O’Mara:

On May 31, 2013, the U.S. Environmental Protection Agency (EPA) received
a revision to the Delaware State Implementation Plan (SIP) from the
Delaware Department of Natural Resources and Environmental Control.  The
SIP revision addresses the requirements of the Clean Air Act section 110
infrastructure elements for the 2010 sulfur dioxide (SO2) national
ambient air quality standards.  EPA has determined that the submittal is
administratively and technically complete, and is being reviewed to
prepare a Notice of Proposed Rulemaking (NPR). 

 

If members of your staff have any questions, they may direct them to
Rose Quinto, Office of Air Program Planning at (215) 814-2182, or at
quinto.rose@epa.gov.  She is the principal contact for this rulemaking.

Sincerely, 

							/s/

        	Diana Esher, Director

Air Protection Division
