Draft Air Quality Permits 7330, 7331, and 7332, Gallaudet University
Construction and operation of three natural gas-fired internal combustion engine based combined heat and power units

Notice is hereby given that, pursuant to 20 DCMR §210, the Air Quality Division (AQD) of the Department of Energy and Environment (DOEE), located at 1200 First Street NE, 5^th Floor, Washington, DC, intends to issue permits (Nos. 7330, 7331 and 7332) to Gallaudet University to construct and operate three (3) 1,500 kWe combined heat and power (CHP) generator sets, each powered by a 2,095 hp natural gas-fired internal combustion engine, at the Central Utility Building of Gallaudet University, 800 Florida Avenue NE, Washington, DC.  The contact person for the facility is David Good, Director, Energy, Utilities, and Sustainability, at (202) 651-5758.

The following CHP units are to be permitted:

The proposed emission limits are as follows:

a.   Emissions from each engine, before the application of selective catalytic reduction (SCR), shall not exceed those in the following table [40 CFR 60.4233(e) and Subpart JJJJ, Table 1]:

¹The Permittee may choose to comply with the emission standards in this table in units of either g/HP-hr or ppmvd at 15 percent O₂.

²For purposes of this requirement, when calculating emissions of VOCs, emissions of formaldehyde should not be included.

b.   After application of SCR, required per Condition III(c), emissions from each CHP unit shall not exceed those in the following table [20 DCMR 201 and 20 DCMR 805.7(a)(2)]:

³This is a streamlined emission limit. The requirements of 20 DCMR 805.7(a)(2) are less stringent than the manufacturer’s guarantee requested by the applicant and included pursuant to 20 DCMR 201. As such, compliance with this limit will ensure compliance with both regulations.

c.   Visible emissions shall not be emitted into the outdoor atmosphere from the 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]

d.   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 estimated maximum emissions from the equipment are as follows:
