The proposed emission limits are as follows:

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



Short-Term Limit

(Natural Gas) (lb/hr)

Short-Term Limit

(Diesel Fuel Oil) (lb/hr)

Carbon Monoxide (CO)



Oxides of Nitrogen (NOx)



Total Particulate Matter (PM Total)*



Volatile Organic Compounds (VOC)



Sulfur Dioxide (SO2)



*PM Total includes both filterable and condensable fractions.

b.   Visible emissions shall not be emitted into the outdoor atmosphere from this boiler, 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].

c.   Particulate matter emissions from the boiler shall not be greater than 0.08 pounds per million BTU. [20 DCMR 600.1]

  1. 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]
  1. NOx and CO emissions shall not exceed those achieved with the performance of annual combustion adjustments on the boiler. To show compliance with this condition, the Permittee shall, each calendar year, perform adjustments of the combustion processes of the boiler with the following characteristic [20 DCMR 805.8(a) and (b)]:
  1. Inspection, adjustment, cleaning or replacement of fuel burning equipment, including the burners and moving parts necessary for proper operation as specified by the manufacturer;
  1. Inspection of the flame pattern or characteristics and adjustments necessary to minimize total emissions of NOx and , to the extent practicable, minimize emissions of CO;
  1. Inspection of the air-to-fuel ratio control system and adjustments necessary to ensure proper calibration and operation as specified by the manufacturer; and

4.   Adjustments shall be made such that the maximum emission rate for any contaminant does not exceed the maximum allowable emission rate as set forth in this section.

The estimated maximum potential emissions from the boiler are as follows:


Maximum Annual Emissions Using Exclusively Natural Gas (tons/yr)

Maximum Annual Emissions Using Exclusively No. 2 Fuel Oil (tons/yr)

Carbon Monoxide (CO)



Oxides of Nitrogen (NOx)



Total Particulate Matter , PM (Total)



Volatile Organic Compounds (VOCs)



Sulfur Dioxide (SO2)



The application to construct and operate the boiler and the draft permit and supporting documents are available for public inspection at AQD and copies may be made available between the hours of 8:15 A.M. and 4:45 P.M.
