Notice of Draft Title V Permit Public Comment Period – Verizon Washington DC, Inc. – Southwest Central Office

Friday, February 1, 2019



Notice is hereby given that Verizon Washington DC, Inc. – Southwest Central Office 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 the following emission units and miscellaneous sources of air emissions at the facility located at 30 E Street SW, Washington DC 20016:

  • Four (4) 1,500 kW emergency generators (EG1, EG2, EG3, and EG4);
  • One (1) 225 kW generator (LSEG1);
  • Three 20,000-gallon underground storage tanks;
  • Two 150-gallon day tanks; and
  • Two chillers

The contact person for the facility is Mr. David Leland, Regional Environmental Manager, at (469) 886-4483 or [email protected].

The following is an estimate of the 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 Verizon Washington DC, Inc. – Southwest Central Office facility has the potential to emit approximately 24.48 tons per year of oxides of nitrogen (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. 045-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 at

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
