Draft Air Quality Permits 6745-R1, 6746-R1, and 6747-R1 - U.S. Department of the Navy

Friday, September 13, 2019


Draft Air Quality Permits 6745-R1, 6746-R1, and 6747-R1, U.S. Department of the Navy, Joint Base Anacostia-Bolling, Operation of three existing 30.25 MMBTU/hr dual fuel-fired (natural gas and No. 2 fuel oil) boilers at 18 Brookley Avenue SW

Notice is hereby given that, pursuant to 20 DCMR § 210, the Air Quality Division (AQD) of the Department of Energy and  Environment (DDOE), located at 1200 First Street NE, 5th Floor, Washington DC, intends to issue air quality permit Nos.  6745-R1, 6746-R1, and 6747-R1 to the U.S. Department of the Navy, Joint Base Anacostia-Bolling to operate three existing boilers rated at 30.25 MMBtu per hour heat input when operating using natural gas and 28.8 MMBTU/hr heat input when operating using No. 2 fuel oil. These boilers are located at Joint Base Anacostia-Bolling, Building 18. The base is located at 370 Brookley Avenue SW, Washington DC 20032; Building 18 is located at 18 Brookley Avenue SW, Washington DC 20032. The contact person for the facility is Paul D’Ornellas, Installation Environmental Program Director, Joint Base Anacostia-Bolling, at (202) 767-0193. 


Maximum emissions from the three units with operating constraints (total combined boiler operations of 13,872 hours per year) are expected to be as follows:


Maximum Annual Emissions



Total Particulate Matter (PM Total)


Oxides of Sulfur (SOx)


Oxides of Nitrogen (NOx)


Volatile Organic Compounds (VOC)


Carbon Monoxide (CO)


The proposed overall emission limits for the equipment are as follows:

a.   Each of the three boilers shall not emit pollutants in excess of those specified in the following tables [20 DCMR 201]:

Boiler Emission Limits




Each Boiler Individually

Total Combined

Annual Emissions Limit From the Three Boilers


Short-Term Limit

(Natural Gas) (lb/hr)

Short-Term Limit

(#2 Fuel Oil) (lb/hr)

Carbon Monoxide (CO)




Oxides of Nitrogen (NOx)




Total Particulate Matter (PM Total)*




Volatile Organic Compounds (VOC)




Oxides of Sulfur (SOx)




*PM Total includes both filterable and condensable fractions.

b.   Total suspended particulate matter emissions from each of the boilers shall not be greater than 0.08 pounds per million BTU.  [20 DCMR 600.1].

c.   Visible emissions shall not be emitted from these units except that discharges not exceeding 40% opacity (unaveraged) shall  be permitted for two (2) minutes in any sixty (60) minutes period and for an aggregate of twelve (12) minutes in any twenty-four (24) hours period during start-up, cleaning, adjustment of combustion controls, or malfunction of the equipment. [20 DCMR 606.1].

d.   In addition to the requirements of Condition (c), no greater than 20% opacity shall be permitted except for one six minute period per hour of not more than 27% opacity when burning No. 2 fuel oil. [40 CFR Subpart Dc, 60.43c(c) and 20 DCMR 205]

e.   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 likely to be injurious to the public health or welfare, or which interferes with the reasonable enjoyment of life and property is prohibited. [20 DCMR 903.1]

      f.    NOx and CO emissions shall not exceed those achieved with the performance of annual combustion adjustments on each boiler. To show compliance with this condition, the Permittee shall, each calendar year, perform adjustments of the combustion processes of the boilers with the following characteristics [20 DCMR 805.5(a) and 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 NOx 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 permit application package and the supporting documentation, along with the draft permits 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. Monday through Friday. Interested parties wishing to view these documents should provide their names, addresses, telephone numbers and affiliation, if any, to Stephen S. Ours at (202) 535-1747.

Interested persons may submit written comments or may request a hearing on this subject within 30 days of publication of this notice. The written comments must also include the person’s name, telephone number, affiliation, if any, mailing address and a statement outlining the air quality issues in dispute and any facts underscoring those air quality issues. All relevant comments will be considered in issuing the final permit.

Comments on the proposed permits and any request for a public hearing should be addressed to:
