Friday, February 16, 2018


Draft Air Quality Permits 7180 through 7187, The Catholic University of America, Construction and operation of eight 6.0 MMBTU/hr dual fuel fired boilers at 620 Michigan Avenue NE

Notice is hereby given that, pursuant to 40 C.F.R. Part 51.161, D.C. 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, 5th Floor, Washington, DC, intends to issue Permit Nos. 7180 through 7187 to The Catholic University of America to construct and operate eight (8) identical 6.0 million Btu per hour dual fuel fired boilers at 620 Michigan Avenue NE, Washington DC 20064. The contact person for the facility is Margaret M. Carney, Associate Vice President for Facilities Planning and Management, at (202) 319-5789.


Maximum potential emissions from the equipment are not expected to exceed the following:



Maximum Estimated Emissions from All Eight Units (Tons Per Year)

Oxides of Nitrogen (NOx)


Volatile Organic Compounds (VOC)


Sulfur Dioxide (SO2)


Total Particulate Matter (PM Total)*


Carbon Monoxide (CO)


Total Hazardous Air Pollutants (HAP)


*PM Total includes both filterable and condensable fractions.

Emission Limitations:

The following are the emission limits proposed for inclusion in the permit:

    1. Each of the eight (8) 6.0 MM BTU per hour dual fuel–fired boilers 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
(No. 2 Fuel Oil) (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.

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]

  1. Total suspended particulate matter (TSP) emissions from each of the boilers 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.   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 805.8(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 the emission limitations in this permit.   

The permit applications and 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 public 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 permits.

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

S. Ours, P.E. Chief, Permitting Branch
Air Quality Division - Department of Energy and Environment
