Kitchen equipment are listed under Section IV under Miscellaneous/Insignificant activities.
These units were previously permitted under the stated Chapter 2 permit numbers. The reference here is for informational purposes only.

Additionally, the facility includes the following miscellaneous activities that have the potential to emit oxides of nitrogen, and are therefore addressed by this application:

The Permittee reported that the nameplate data is illegible due to corrosion. The capacities stated here are estimated based on AP-42 emission factor for residential furnaces.

The contact person for the facility is Mr. Anthony Kesslak at (202)-482-2520 or [email protected].

The applicant has requested that limitations on the operation of the emergency generator sets be established in the permit pursuant to 20 DCMR § 200.6 to avoid the applicability of 20 DCMR § 300.1, and pursuant to 20 DCMR § 200.7 to avoid applicability of 20 DCMR § 204. Specifically, the applicant has requested 400 hour per 12-month rolling period operational limitations for each of the emergency generator sets (Unit 1, Unit 2, and Unit 3)) and a limit on the hours of operation of the kitchen equipment not to exceed eighteen (18) hours in any twenty-four (24) hour 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)

0.029

Oxides of Nitrogen (NOx)

23.95

Particulate Matter (PM)

0.438

Volatile Organic Compounds (VOCs)

0.629

Carbon Monoxide (CO)

2.187

With the operational limitations included in the draft permit, the United States Department of Commerce facility has the potential to emit approximately 23.95 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.

The Department of Energy and Environment (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. 7322-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 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. 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:
