Model Number

Natural Gas Rating (MMBTU/hr)

Permit Number

Boiler 1 - B1

Fulton Vantage VTG-6000



Boiler 2 - B2

Fulton Vantage VTG-6000



Boiler 3 - B3

Fulton Vantage VTG-6000



Boiler 4 - B4

Fulton Vantage VTG-6000



Boiler 5 - B5

Each Boiler

Boilers (Sum)

Total Particulate Matter (PM Total)



Sulfur Dioxide (SO2)



Nitrogen Oxides (NOx)



Volatile Organic Compounds (VOC)



Carbon Monoxide (CO)



The proposed emission limits are as follows:

    1. Each of the six (6) 6.0 MMBTU per hour natural gas fired boilers shall not emit pollutants in excess of those specified in the following table [20 DCMR 201]:

Boiler Emission Limits


Short-Term Limit (lb/hr)

Carbon Monoxide (CO)


Oxides of Nitrogen (NOx)


Total Particulate Matter (PM Total)


Sulfur Dioxide (SO2)


*PM Total includes both filterable and condensable fractions.

    1.    Visible emissions shall not 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]

[20 DCMR 903.1]
  2. Total suspended particulate matter (TSP) emissions from each of the boilers shall not exceed 0.11 pound per million BTU. [20 DCMR 600.1]

The applications to construct and operate the boilers and the draft permits 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.
