The contact person for the facility is Ms. Mamie Bittner at (202)228-1793 or [email protected].

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

 

FACILITY-WIDE EMISSIONS SUMMARY [TONS PER YEAR]

Pollutants

Potential Emissions

Sulfur Dioxide (SO2)

0.03

Oxides of Nitrogen (NOx)

39.24

Total Particulate Matter (PM Total)

2.10

Volatile Organic Compounds (VOCs)

1.04

Carbon Monoxide (CO)

2.21

Total Hazardous Air Pollutants (HAPs)

0.02

This facility has the potential to emit 39.24 tons per year of oxides of nitrogen (NOx). The value for this criteria pollutant exceeds the major source thresholds in the District of Columbia of 25 TPY of NOx. Because potential emissions of NOx exceed the relevant major source threshold, pursuant to 20 DCMR 300.1(a), the source is subject to Chapter 3 and must obtain an operating permit in accordance with that regulation and Title V of the federal Clean Air Act.

The 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. 051 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 http://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:
