Friday, August 10, 2018

PUBLIC NOTICE

Draft Air Quality Permit 7207, American University, Construction and operation of one 11.5 MMBTU/hr natural gas-fired microturbine at the Asbury Hall central steam plant, 4400 Massachusetts Avenue 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.7207 to American University to construct and operate one (1) natural gas-fired modular microturbine to be located at the Asbury Hall central steam plant, 4400 Massachusetts Avenue NW, Washington DC. The contact person for the facility is Mark A. Freedman, Manager, Energy Utilities Operations, at (202) 885-2378.

The following modular microturbine is to be permitted:

Equipment Location

Emission Unit ID

Model Number

Heat Input Rating (MMBTU/hr)

Permit Number

Asbury Hall Central Plant

4400 Massachusetts Ave NW

Washington DC

CHP-1

C1000S

11.5

7207

Emissions:

The estimated maximum annual emissions from the microturbine are expected to be as follows:

                                                  

Pollutant

Maximum Annual Emissions

(tons/yr)

Total Particulate Matter (PM Total)

0.350

Sulfur Dioxide (SO2)

0.175

Nitrogen Oxides (NOx)

1.75

Volatile Organic Compounds (VOC)

0.438

Carbon Monoxide (CO)

4.82

The proposed emission limits are as follows:

a.   The microturbine system shall not emit pollutants in excess of the following [20 DCMR 201]:

MicroTurbine Emission Limits (lb/hr)

Pollutant

C1000S

Carbon Monoxide (CO)

1.10

Oxides of Nitrogen (NOx)

0.40

Total Particulate Matter (PM Total)*

0.08

Volatile Organic Compounds (VOC)

0.10

*PM Total includes both filterable and condensable fractions.

b.   Visible emissions shall not be emitted into the outdoor atmosphere from the microturbine, except that discharges not exceeding forty percent (40 %) opacity (averaged) 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, if any, or malfunction of the microturbine. [20 DCMR 606.1]

  1. The Permittee shall not burn in the unit any fuel that contains total potential sulfur emissions in excess of 0.060 lb SO2/MMBtu heat input. [40 CFR 60.4330(a)(2)]
     
  2. NOx emissions from the microturbine shall not exceed 25 ppmvd corrected to 15% O2 [20 DCMR 805.4(a)(3)(A)(i) and 40 CFR 60.4320] Note that this is a streamlined requirement. The requirements of 20 DCMR 805.4(a)(3)(A)(i) are more stringent than the requirements of 40 CFR 60.4320. Compliance with this condition will ensure compliance with both requirements.

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 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]     

The application to construct and operate the boilers and the draft permits 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. 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 permits.


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