PUBLIC NOTICE
AIR QUALITY TITLE V OPERATING PERMIT AND
GENERAL PERMIT FOR
SAINT ELIZABETHS WEST CAMPUS
Notice is hereby given that U.S. General Services Administration 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 notable emission units: two (2) 16.63 MMBtu/hr dual-fuel boilers; two (2) 12.45 MMBtu/hr dual-fuel boilers; four (4) small hot water heaters; two (2) 2191 kW emergency generators; two (2) 2711 kW emergency generators; one (1) 2180 kW pump house emergency generator, and one (1) trailer-mounted 620 kW emergency generator, at Saint Elizabeths West Campus located at 2701 Martin Luther King, Jr. Ave. SE, Washington DC. The contact person is Everett Smallwood, Customer Service Manager, at (202) 438-8471.
Saint Elizabeths West Campus (SEWC), has the potential to emit 19.86 tons per year (TPY) of nitrogen oxides (NOx), 1.00 TPY of sulfur dioxide (SO2), 1.44 TPY of particulate matter (PM), 1.50 TPY of volatile organic compounds (VOC), and 17.50 TPY of carbon monoxide.
Under normal maximum operating conditions for determination of the potential emissions of the facility (i.e., 500 hours per year per emergency generator), the combined emissions of the generators could possibly have exceeded the major source thresholds, and thus trigger a Non Attainment New Source Review (NNSR). In order to avoid this possibility, the facility opted for fuel and operating hour restrictions to keep their potential to emit nitrogen oxides under the major source threshold. The Chapter 3 permitting process is being used in this case to make these limits federally enforceable and enforceable as a practical matter.
Description and Emission Information for Unit being Permitted for the First Time
A trailer-mounted Caterpillar emergency diesel generator described below was neither in the initial Title V Permit application submitted to the District Department of the Environment nor permitted under the Chapter 2 Permit provisions of Title 20 of the District of Columbia Municipal Regulations, 20 DCMR. By way of this notice, the requirements of the Chapter 2 permit for this new emergency generator are hereby incorporated into the facility’s Title V operating permit being processed. The emergency generator is subject to the requirements of the New Source Performance Standards (NSPS), and these form the basis of the emission limits listed below.

The proposed emission limits for the new emergency generators are as follows:

[20 DCMR 606.1]
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]
