Dear Secretary O’Mara:

On February 21, 2014, 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 pertains to 7 Del. Admin Code 1103 – Ambient Air
Quality Standards, which brings Delaware’s regulatory standards up to
date with current Federal requirements.  EPA has determined that the
submittal is administratively and technically complete, and is being
reviewed to prepare a Direct Final Rulemaking Notice. 

 

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
