Notice Requesting Public Comment on Air Quality Operating Permit for AT&T

Notice Requesting Public Comment on Draft Title V and Chapter 2 Air Quality Operating Permit for AT&T Corporation

Notice is hereby given that AT&T Corporation (AT&T) has applied for a 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 operate the following equipment at the facility located at 725 13th Street NW, Washington, DC 20005:

  • Two (2) 1,600 kWe emergency generator sets powered by 2,145 hp diesel engines; and
  • One (1) 1,750 kWe emergency generator set powered by a 2,561 hp diesel engine.

The contact person for the facility is Ms. Jalayna Bolden, Assistant Secretary at (214) 748-5702.

The facility would have the potential to emit greater than 25 tons per year (TPY) of oxides of nitrogen, the threshold for being designated a major source in the District of Columbia if all three generators were assessed assuming 500 hours per year of operation, as is usually done for such equipment. However, the applicant requested a federally enforceable limit of 340 hours per year of operation for each of the 1,600 kWe generator sets to ensure that emissions remain below this threshold. This limit is being placed in the Title V permit as a federally enforceable limit on the potential to emit of the facility.

With this 340 hour operational limit on each of the two 1,600 kWe generator sets and the standard 500 hour per year limit on the 1,750 kWe generator set, the facility has the potential to emit the following pollutants:

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 #049 has been prepared.

Copies of the draft permit and related fact sheet are also available in the attachment section 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.
