Notice of action: The Department of Environmental Quality (DEQ) is announcing an opportunity for public comment on a revision to the Commonwealth's state implementation plan (SIP) to attain and maintain the national ambient air quality standard for ozone in the Northern Virginia Ozone Nonattainment Area. The Commonwealth intends to submit the plan revision in accordance with the requirements of § 110(a) of the federal Clean Air Act. The SIP is the plan developed by the Commonwealth in order to fulfill its responsibilities under the federal Clean Air Act to attain and maintain the ambient air quality standards promulgated by the U.S. Environmental Protection Agency (EPA) under the Act.

Purpose of notice: DEQ is seeking comments on the overall plan revision.

Public comment period: April 8 to May 8, 2013.

Public hearing: A public hearing will be conducted if a request is made in writing to the contact listed below. In order to be considered, the request must include the full name, address and telephone number of the person requesting the hearing and be received by DEQ on the last day of the comment period. Notice of the date, time, and location of any requested public hearing will be announced in a separate notice, and another 30-day comment period will be conducted.

Description of proposal: The proposed revision consists of the removal from Virginia's SIP of reference to two permits and a consent agreement for the GenOn (formerly PEPCO) Potomac River Generating Station, Alexandria, Virginia. On December 12, 2012, the department and the company entered into a mutual determination of permanent shutdown of the entire facility. All permits and consent agreements, including the 2 permits and consent agreement that had been previously approved by EPA into SIP, were rescinded as part of the shutdown agreement. There is therefore no longer a need for reference to these documents in the SIP.

Federal information: This notice is being given to satisfy the public participation requirements of federal regulations (40 CFR 51.102).  The proposal will be submitted as a revision to the Commonwealth of Virginia SIP under § 110(a) of the federal Clean Air Act in accordance with 40 CFR 51.104.  It is planned to submit all provisions of the proposal as a revision to the Commonwealth of Virginia SIP.

How to comment: DEQ accepts written comments by email, fax, and postal mail.  In order to be considered, comments must include the full name, address and telephone number of the person commenting and be received by DEQ on the last day of the comment period. All materials received are part of the public record.
