PUBLIC NOTICE

AIR QUALITY TITLE V OPERATING PERMIT AND GENERAL PERMIT FOR THE Architect of the Capitol, Library Buildings and Grounds Jurisdiction

Notice is hereby given that the Architect of the Capitol, Library Buildings and Grounds Jurisdiction has applied for a Title V air quality permit pursuant to the requirements of Title 20 of the District of Columbia Municipal Regulations, Chapters 2 and 3 (20 DCMR Chapters 2 and 3) to operate the following emission units and miscellaneous sources of air emissions at the Library of Congress, located at 101 Independence Ave SE, Washington DC 20540:

Miscellaneous Activities:

1.  One (1) Underground Storage Tank (UST) for diesel;

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

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

4.   Four (4) Reservoirs for hydraulic oil; and

5.   Two (2) carpentry shop dust collectors.

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 (NO_x). The value for this criteria pollutant exceeds the major source thresholds in the District of Columbia of 25 TPY of NO_x. Because potential emissions of NO_x 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:

Emission Unit ID	Emission Unit Identification
Parts Washer 1	Dyna Clean Model No. 915201 located in the metal shop in the Thomas Jefferson Building
Parts Washer 2	Dyna Clean Model No. 915201 located in the machine shop in the Thomas Jefferson Building
Parts Washer 3	Dyna Clean Model No. 915201 located on the 7th Floor of the James Madison Memorial Building

   

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.
