Official Code §2-505, and 20 DCMR §210, the Air Quality Division (AQD) of the Department of Energy and Environment (DOEE), located at 1200 First Street NE, 5^th Floor, Washington, DC, intends to issue Permit #5734-R1 to the District of Columbia Water and Sewer Authority (DC Water) to operate one (1) Burnham 8.31 MMBtu per hour natural gas-fired boiler, located at the Grit Chamber Building 2, 5000 Overlook Avenue, SW, Washington, DC. The contact person for the facility is Meena Gowda, Principal Counsel, at (202) 787-2628.

Boiler to be Permitted

Equipment Location	Address	Boiler Size	Boiler Model Number	Permit No.
Blue Plains WWTP-Grit Chamber Bldg 2	5000 Overlook Ave., SW Washington, DC	8.31 MMBtu/hr	Burnham 4FW99350GGP	5734-R1

The proposed emission limits are as follows:

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

Pollutant	Short-Term Limit (Natural Gas) (lb/hr)
Carbon Monoxide (CO)	0.68
Oxides of Nitrogen (NOx)	0.81
Total Particulate Matter (PM Total)*	0.06
Sulfur Dioxide (SO2)	0.005

*PM Total includes both filterable and condensable fractions.

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

3. Particulate matter emissions from the boiler shall not be greater than 0.11 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]

e.   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 boiler combustion process adjustments with the following characteristics [20 DCMR 805.1(a)(4) and 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;

2.   Inspection of the flame pattern or characteristics and adjustments necessary to minimize total emissions of NO_x and, to the extent practicable, minimize emissions of CO;

3.   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 emissions from the boiler is as follows:

Pollutant	Maximum Annual Emissions Using Natural Gas Only (tons/yr)
Carbon Monoxide (CO)	3.00
Oxides of Nitrogen (NOx)	3.57
Total Particulate Matter (PM Total)	0.27
Volatile Organic Compounds (VOCs)	0.20
Sulfur Dioxide (SO2)	0.021

The application to 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.
