2.   Nine (9) Aboveground Storage Tanks (ASTs) for diesel

3.   Thirty-four (34) Wet-Type Transformer Vaults for mineral oil;

The contact person for the facility is Mr. Jonathan Shriner, Assistant Superintendent, at (202) 707-2823 or [email protected]

The following is an estimate of overall potential emissions from the facility:

FACILITY-WIDE EMISSIONS SUMMARY [TONS PER YEAR]

Pollutants

Potential Emissions

Sulfur Dioxide (SO2)

0.38

Oxides of Nitrogen (NOx)

38.03

Total Particulate Matter (PM Total)

1.43

Volatile Organic Compounds (VOCs)

2.33

Carbon Monoxide (CO)

6.90

Total Hazardous Air Pollutants (HAPs)

0.02

This facility has the potential to emit 38.03 tons per year of oxides of nitrogen (NOx). The value for this criteria pollutant exceeds the major source thresholds in the District of Columbia of 25 TPY of NOx. Because potential emissions of NOx exceed the relevant major source threshold, pursuant to 20 DCMR 300.1(a), the source is subject to Chapter 3 and must obtain an operating permit in accordance with that regulation and Title V of the federal Clean Air Act.

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

The proposed emission limits for the parts washers (cold cleaning machines) 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]

b.   No solvents shall be used in the units that contain halogenated hazardous air pollutant (HAP) solvents in excess of five percent (5%) by weight as follows [20 DCMR 201]:

i.    Methylene chloride;
ii.   Perchloroethylene;
iii.  Trichloroethylene;
iv.  1,1,1-trichloroethane; or
v.   Chloroform.

Estimated Emissions from Parts Washers

The estimated maximum potential emissions from the cold cleaning machines are 0.99 tons per year of VOCs.
