Dear Mr. Aburn:

	On July 13, 2007, EPA received a revision to the Maryland State
Implementation Plan (SIP) from the Maryland Department of the
Environment (MDE) pertaining to emission limitations and related
requirements for nitrogen oxides (NOx) and sulfur dioxide (SO2) at 15
coal-fired electric generating units in Maryland.  EPA has determined
that the submittal is administratively and technically complete, and is
reviewing it to prepare a (Notice of Proposed Rulemaking (NPR). 

	If members of your staff have any questions, they may direct them to
Irene Shandruk, Air Quality Planning Branch, at (215) 814-2166.  She is
the principal contact for this rulemaking.    

Sincerely, 

						/s/
