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

The applicant has requested that limitations on the operation of the five emergency generator sets be established in the permit pursuant to 20 DCMR § 200.6 to avoid the applicability of 20 DCMR § 300.1. Specifically, the applicant has requested that the four 1,500 kWe emergency generator sets be limited to operating no more than 400 hours, each, in any 12-consecutive-month period and that the 250 kWe generator set be limited to operating no more than 125 hours in any 12-consecutve-month period.

Factoring in these operational limits, the following is an estimate of the overall potential emissions from the facility:

 

FACILITY-WIDE EMISSIONS SUMMARY [TONS PER YEAR]

Pollutants

Potential Emissions with 20 DCMR 200.6 Limits

Sulfur Dioxide (SO2)

0.021

Oxides of Nitrogen (NOx)

22.27

Coarse Particulate Matter (PM10)

0.44

Volatile Organic Compounds (VOCs)

1.74

Carbon Monoxide (CO)

2.56

With the operational limitations included in the draft permit, the Verizon Washington DC, Inc. – Southwest Central Office facility has the potential to emit approximately 22.27 tons per year of oxides of nitrogen (NOx), which is below the District’s major source threshold of 25 tons per year of NOx. Similarly, all other pollutants’ potential emissions are below their respective major source thresholds. As such, the facility is properly classified as a synthetic minor source pursuant to 20 DCMR § 300.3(c) and can avoid the applicability of a permit pursuant to 20 DCMR § 300.1.

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. 7290-SM has been prepared.

The permit application and supporting documentation, along with the draft permit are available for public inspection at AQD and copies may be made available between the hours of 8:15 A.M. and 4:45 P.M. Monday through Friday. Interested parties wishing to view these documents should provide their names, addresses, telephone numbers and affiliation, if any, to Stephen S. Ours at (202) 535-1747. Copies of the draft permit and related technical support memorandum are also available in the attachments 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. The written comments must include the person’s name, telephone number, affiliation, if any, mailing address and a statement outlining the air quality issues in dispute and any facts underscoring those air quality issues. All relevant comments will be considered in issuing the final permit.

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