The contact person for the facility is Mr. Nicholas Carros at (202)-736-4705 or [email protected]

The applicant has requested that limitations on the operation of the boilers and 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 100 hour per year operational limitations for the twelve emergency generator sets (E-41-2, E-41-3, E-41-5, E-41-6, E-41-8, E-41-9, E-41-10, E-41-11, E-41-12, E-41-15, E-41-16, and E-41-17) and a limit on total natural gas consumption at the facility not to exceed 121.298 million standard cubic feet (MMSCF) per twelve-consecutive-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)

0.24

Oxides of Nitrogen (NOx)

20.41

Particulate Matter (PM)

4.06

Volatile Organic Compounds (VOCs)

1.18

Carbon Monoxide (CO)

6.02

With the operational limitations included in the draft permit, the United States Department of State facility has the potential to emit approximately 20.41 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.

Description and Emission Information for Units Being Permitted for the First Time:

The following units are being permitted for the first time through this permitting action. After the table of units, the proposed emission limits are specified.

Emergency Generator Sets Powered by Compression Ignition Internal Combustion Engines (CI-ICE) not subject to New Source Performance Standards (NSPS): Nine (9) emergency standby generator sets powered by diesel-fired engines not subject to NSPS Subpart IIII, but subject to National Emission Standards for Hazardous Air Pollutants (NESHAP) Subpart ZZZZ as described in the following table:

Emissions Limitations:

A.  Visible emissions shall not be emitted into the outdoor atmosphere from these generators, except that discharges not exceeding forty percent (40%) opacity (unaveraged) shall be permitted for two (2) minutes in any sixty (60) minute period and for an aggregate of twelve (12) minutes in any twenty-four hour (24 hr.) period during start-up, cleaning, adjustment of combustion controls, or malfunction of the equipment. [20 DCMR 606.1]

B.  An emission into the atmosphere of odorous or other air pollutants from any source in any quantity and of any characteristic, and duration which is, or is likely to be injurious to the public health or welfare, or which interferes with the reasonable enjoyment of life or property is prohibited. [20 DCMR 903.1]

C.  Emissions of NOx from each of the generator sets shall not exceed the following:

i.    0.031 lb/hp-hr for the following engines less than 600 hp. [20 DCMR 200.6, 20 DCMR 200.7, and 20- DCMR 201]

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. 7305-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 availablein 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:
