Emissions:

The estimated maximum annual emissions from each of the three (3) 5.24 MMBtu/hr dual fuel-fired (natural gas and No. 2 fuel-oil) boilers, assuming 8,760 hours per year of operation at maximum capacity on the highest-polluting allowable fuel, are expected to be as follows:

	Maximum Annual Emissions for Each Boiler
Pollutant	(tons/yr)
Total Particulate Matter (PM Total)	0.54
Sulfur Dioxide (SO2)	1.18
Oxides of Nitrogen (NOx)	3.28
Volatile Organic Compounds (VOC)	0.13
Carbon Monoxide (CO)	1.93

The proposed boiler emission limits are as follows:

1. 1. Each of the boilers (identified as Hurst Boiler #1, Hurst Boiler #2, and Hurst Boiler #3) shall not emit pollutants in excess of those specified in the following table [20 DCMR 201]:

Pollutant	Short-Term Limit (Natural Gas) (lb/hr)	Short-Term Limit (No. 2 Fuel oil) (lb/hr)
Carbon Monoxide (CO)	0.441	0.187
Oxides of Nitrogen (NOx)	0.525	0.748
Total Particulate Matter (PM Total)1	0.040	0.123
Sulfur Dioxide (SO2)	0.003	0.269
Volatile Organic Compounds (VOC)	0.029	0.029

¹PM Total includes both filterable and condensable fractions.

b.   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]

3. Total suspended particulate matter (TSP) emissions from the each of the boilers shall not be greater than 0.12 pounds per million BTU. [20 DCMR 600.1].

d.   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]
