Friday, October 19, 2018

PUBLIC NOTICE

Draft Air Quality Permit 7231, Howard University, Construction and operation of one 8.27 6.0 MMBTU/hr natural gas-fired boiler at the Howard University Service Center, 2244 10th Street NW

Notice is hereby given that, pursuant to 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 No. 7231 to Howard University to construct and operate one 8.27 million Btu per hour natural gas-fired boiler at the Howard University Service Center located at 2244 10th Street NW, Washington DC 20059. The contact person for the facility is Susan Dreyer, Director of Environmental, Health, and Safety, at (202) 806-1006.

Emissions:

The estimated maximum annual emissions from the 8.27 MMBTU/hr natural gas-fired boiler are expected to be as follows:

                                                   

Maximum Annual Emissions
for Each Boiler

Pollutant

(tons/yr)

Total Particulate Matter (PM Total)

0.27

Sulfur Dioxide (SO2)

0.021

Nitrogen Oxides (NOx)

2.64

Volatile Organic Compounds (VOC)

0.20

Carbon Monoxide (CO)

1.34

The proposed emission limits are as follows:

a.   This 8.27 MMBTU per hour natural gas fired boiler shall not emit pollutants in excess of those specified in the following table [20 DCMR 201]:

Boiler Emission Limits

Pollutant

Short-Term Limit (lb/hr)

Carbon Monoxide (CO)

0.31

Oxides of Nitrogen (NOx)

0.60

Total Particulate Matter (PM Total)

0.06

Sulfur Dioxide (SO2)

0.005

*PM Total includes both filterable and condensable fractions.

  1. 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]

c.   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]

d.   Total suspended particulate matter (TSP) emissions from the boiler shall not exceed 0.11 pound per million BTU. [20 DCMR 600.1]

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 805.1(a)(4) and 20 DCMR 805.8(a) and (b)]:

i.    Inspection, adjustment, cleaning or replacement of fuel burning equipment, including the burners and moving parts necessary for proper operation as specified by the manufacturer;

ii.    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;

iii.   Inspection of the air-to-fuel ratio control system and adjustments necessary to ensure proper calibration and operation as specified by the manufacturer; and

iv.   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 Condition II of this permit.

The permit application and supporting documentation, along with the draft permit is 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.
