Notice Requesting Public Comment on Draft Title V and Ch. 2 Air Quality Operating Permit - Virginia Electric and Power Co

Friday, October 6, 2017


Notice Requesting Public Comment on Draft Title V and Chapter 2 Air Quality Operating Permit Significant Modification for Virginia Electric and Power Co. dba Dominion Virginia Power Operations at Joint Base Myer-Henderson Hall (Fort Lesley J. McNair)

Notice is hereby given that Virginia Electric and Power Co. dba Dominion Virginia Power has applied for a Title V air quality permit significant modification pursuant to the requirements of Title 20 of the District of Columbia Municipal Regulations, Chapters 2 and 3 (20 DCMR Chapters 2 and 3). The modification will add a thirteenth diesel-fired emergency generator set to the previously issued permit to operate twelve (12) diesel fired emergency generators at Joint Base Myer-Henderson Hall (Fort Lesley J. McNair), located at 4th and P Streets SW, Washington DC. The new emergency generator set consists of a 400 kWe generator powered by a 619 hp diesel-fired engine. The contact person for the applicant is Mr. Andy Gates, at (804) 273-2950.

The following table shows the impact of the addition of the new generator set to the facility’s potential to emit air pollutants:



Criteria Pollutants

Potential Emissions

Before Additional Generator Set

Potential Emissions of Additional Generator Set

Total New Potential Emissions of the Facility

Sulfur Dioxide (SO2)




Oxides of Nitrogen (NOx)




Total Particulate Matter (PM Total)




Volatile Organic Compounds (VOC)




Carbon Monoxide (CO)




With the potential to emit approximately 52.41 tons per year of NOx, the source has the potential to emit greater than the District’s major source threshold of 25 tons per year of NOx. Additionally, these units constitute a support facility for Joint Base Myer-Henderson Hall, which is a separately permitted major source. Therefore, the facility is classified as a major source of air pollution and is subject to 20 DCMR Chapter 3 and must obtain an operating permit under that regulation.

The Department of Energy and Environment (DOEE) has reviewed the permit application and related documents and has made a preliminary determination that the applicant meets all applicable air quality requirements promulgated by the U.S. Environmental Protection Agency (EPA) and the District.  Therefore, draft permit #043-A1 has been prepared.

The application, the draft permit, and all other materials submitted by the applicant [except those entitled to confidential treatment under 20 DCMR 301.1(c)] considered in making this preliminary determination are available for public review during normal business hours at the offices of the Department of Energy and Environment, 1200 First Street NE, 5th Floor, Washington DC 20002. Copies of the draft permit and related fact sheet are available at https://doee.dc.gov/service/public-notices-hearings.

A public hearing on this permitting action will not be held unless DOEE has received a request for such a hearing within 30 days of the publication of this notice.  Interested parties may also submit written comments on the permitting action.

Comments on the draft permit and any request for a public hearing should be addressed to:

Stephen S. Ours  
Chief, Permitting Branch - Air Quality Division
