†    These Chapter 2 permit numbers are for reference only. The requirements of the Chapter 2 permits have been incorporated into the draft permit and the separate Chapter 2 permit documents will no longer be maintained.

‡   These permit numbers were assigned to permit applications that did not result in stand-alone Chapter 2 permits being issued. These permit numbers are included here for reference purposes only.  

In addition to the above equipment, the facility maintains the following insignificant/miscellaneous units:

The contact person for the facility is Mr. Daniel DiRito, at (202) 997-3773 or [email protected]

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

Plantwide Emissions Summary (tons per year)

Total Particulate Matter (PM Total) – includes both filterable and condensable fractions

Total Hazardous Air Pollutants (HAPs)

This facility has the potential to emit (PTE) approximately 33.67 tons per year (TPY) of NOx.

This exceeds the major source threshold for NOx in the District of Columbia of 25 TPY.

Because potential emissions of NOx exceed the major source threshold, pursuant to 20 DCMR 300.1(a), the source is subject to Chapter 3 (Title V) 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:

Detroit Diesel Life Safety Generator, Serial No. 0765031

600 kW generator set powered by a 804 hp diesel engine, installed date 2003 (non-NSPS

Caterpillar Fire Pump, Serial No. 90N69428

121 hp diesel engine-powered fire pump, installed date: 1998 (non-NSPS)

The proposed emission limits for the Life Safety Generator and the Fire Pump are as follows:

A.  Visible emissions shall not be emitted into the outdoor atmosphere from the units, 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 24-hour period during start-up, cleaning, adjustment of combustion controls, or malfunction of the equipment. [20 DCMR 606.1]

B.  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 proposed emission limits for NAC Boilers 1 and 2 are as follows:

A.  The boilers shall not emit pollutants in excess of those specified in the following table [20 DCMR 201]:

(No. 2 Fuel Oil) (lb/hr)

Total Particulate Matter (PM Total)π

π   PM Total includes both filterable and condensable fractions.  

B.  Total suspended particulate matter (TSP) emissions from each boiler shall not exceed 0.08 pounds per million BTU. [20 DCMR 600.1]

C.  No visible emissions shall be emitted into the outdoor atmosphere from the boilers; 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.  NOx and CO emissions shall not exceed those achieved with the performance of combustion process tune-ups as specified in Condition III(b)(2)(E) and (F). [20 DCMR 805.1(a), 20 DCMR 805.5(b), and 20 DCMR 805.9]:

DOEE has reviewed the permit application and related documents and has made a preliminary determination that the applicant meets all applicable air quality requirements promulgated by the U.S. Environmental Protection Agency (EPA) and the District.
