Notice of Draft Title V Permit Renewal Public Comment Period – Children’s National Medical Center

Friday, May 22, 2020

Notice Requesting Public Comment on Draft Title V and Chapter 2 Air Quality Operating Permit for Children’s National Medical Center

Notice is hereby given that Children’s National Medical Center has applied for a renewal of its Title V air quality permit pursuant to the requirements of Title 20 of the District of Columbia Municipal Regulations, Chapters 2 and 3 (20 DCMR Chapters 2 and 3) to continue operation of seven (7) diesel-fired emergency generators; several above and underground storage tanks, fume hoods, wet cooling towers, chillers, x-ray/photography development equipment, natural gas fired kitchen equipment, and laboratory equipment at Children’s National Medical Center, located at 111 Michigan Avenue NW, Washington DC 20010.  The contact person for the facility is Mr. Rodney Eason, Director of Facilities Management at (202) 476-2208 or [email protected].

The following is an estimate of overall potential emissions from the facility:



Potential Emissions

Sulfur Dioxide (SO2)


Oxides of Nitrogen (NOx)


Total Particulate Matter (PM Total)


Volatile Organic Compounds (VOCs)


Carbon Monoxide (CO)


With the emission limitations included in the draft permit, the facility has the potential to emit approximately 24.345 tons per year of nitrogen oxides(NOx), just under the District’s major source threshold of 25 tons per year of NOx. Under normal maximum operating conditions for determination of the potential emissions of the facility (i.e. 500 hours per year per emergency generator), the combined emissions of the equipment would possibly have exceeded the major source threshold for NOx and thus trigger a Non-Attainment New Source Review (NNSR). In order to avoid this possibility, the facility opted for operating hour restrictions to keep their potential to emit NOx under the major source threshold. The Chapter 3 permitting process is being used in this case to make these limits federally enforceable and enforceable as a practical matter.

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 No. 041-R1 has been prepared.

The application, the draft permit and associated Fact Sheet and Statement of Basis, 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 as attachments below.

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
