Official Code §2-505, and 20 DCMR §210, the Air Quality Division (AQD) of the Department of Energy and Environment (DOEE), located at 1200 First Street NE, 5th Floor, Washington, DC, intends to issue Permit No. 7169 to Georgetown University to construct and operate one 40 kWe emergency generator set powered by a 72 hp natural gas fired engine to be located at the Yates Building at Georgetown University, 3700 O Street NW, Washington DC.

The estimated emissions from the generator engine are as follows:

Pollutant

Maximum Annual Emissions (tons/yr)

Carbon Monoxide (CO)

0.65

Oxides of Nitrogen (NOx)

0.21

Total Particulate Matter (PM Total)

0.01

Volatile Organic Compounds (VOCs)

<0.001

Sulfur Dioxide (SOx)

<0.001

The proposed emission limits are as follows:

a.   Emissions from this unit shall not exceed those in the following table [40 CFR 60.4233(e) and Subpart JJJJ, Table 1]:

Pollutant Emission Limits

g/HP-hr

NOx + HC

CO

10

387

b.   Visible emissions shall not be emitted into the outdoor atmosphere from this generator, 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].

Note that 20 DCMR 606 is subject to an EPA-issued call for a State Implementation Plan (SIP) revision (known as a “SIP call”) requiring the District to revise 20 DCMR 606. See “State Implementation Plans: Response to Petition for Rulemaking; Restatement and Update of EPA’s SSM Policy Applicable to SIPs; Findings of Substantial Inadequacy; and SIP Calls To Amend Provisions Applying to Excess Emissions During Periods of Startup, Shutdown and Malfunction”, 80 Fed. Reg. 33840 (June 12, 2015). It is likely that this federal action will result in changes to the requirements of 20 DCMR 606.  Any such changes, once finalized in the DCMR, will supersede the language of Condition II(b) as stated above.

c.   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]

The application to operate the generator set and the draft permit and supporting documents 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.

Interested persons may submit written comments or may request a hearing on this subject within 30 days of publication of this notice.  The written comments must also 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 proposed permit and any request for a public hearing should be addressed to:
