Draft Air Quality Permit 7391, The Howard University, Installation and operation of a cold solvent degreasing unit at 732 N. Capitol Street NW, Washington DC

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, proposes to issue an air quality permit (No. 7391) to the U.S. Government Publishing Office (GPO) to install and operate a 20-gallon capacity OEMTOOLS 24805 mobile remote reservoir cold solvent degreasing unit (also known as a “cold cleaning machine” or “parts washer”), to be located at 732 N. Capitol Street NW, Washington DC. The contact person for the applicant is Daryl Kosturock, Environmental Manager, at (202) 512-1626 or [email protected].

Emissions Estimate:

Maximum potential emissions from the unit are expected to be no greater than the following:

No hazardous air pollutant (HAP) emissions are expected from the unit.

The proposed overall emission limits for the equipment are as follows:

a.   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]

Violation of the requirements of this condition that occur as a result of unavoidable malfunction, despite the conscientious employment of control practices, shall be an affirmative defense for which the owner or operator shall bear the burden of proof. A malfunction shall not be considered unavoidable if the owner or operator could have taken, but did not take, appropriate steps to eliminate the malfunction within a reasonable time, as determined by the Department. [20 DCMR 903.13(b)]

Note: This condition is District enforceable only.

b.   No solvents shall be used in the units that contain halogenated hazardous air pollutant (HAP) solvents as follows [20 DCMR 201]:

1.   Methylene chloride;

2.   Perchloroethylene;

3.   Trichloroethylene;

4.   1,1,1-trichloroethane;

5.   Carbon tetrachloride; or

6.   Chloroform.

It should be noted that emissions are primarily minimized from this type of equipment by operational limitations and procedures set forth in the permit, rather than from explicit emission limits.
