Dear Mr. Paylor:

On September 29, 2010, the U.S. Environmental Protection Agency (EPA)
received a revision to the Virginia State Implementation Plan (SIP) from
the Virginia Department of Environmental Quality.  This revision
consists of a regulation (9VAC5 Chapter 30) that contains the ambient
air quality standards set out in 40 CFR Part 50.  The submittal added an
8-hour ozone standard of 0.075 parts per million (ppm) and related
reference conditions, as well as updated the list of appendices to 40
CFR Part 51 for documents incorporated by reference, 9VAC5-20-21.  EPA
has determined that the submittal is administratively and technically
complete, and is reviewing it to prepare a Direct Final Rulemaking
Notice.

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

		Sincerely, 

						/s/
