The permit numbers and approval numbers listed here are for the Chapter 2 permits and approvals under which these units were previously permitted and are for reference only. The requirements of these permits have been incorporated into this Title V operating permit and these separate Chapter 2 permit numbers and approval numbers will no longer be maintained. Unless otherwise identified by a permit number the emission units are already covered by the existing Title V operating permit.

In addition to the significant units listed above, American University identified in their application the following insignificant units:

  • Twenty-four (24) fuel oil storage tanks (2 underground tanks and 22 aboveground tanks) to support fuel oil storage for emergency generators;
  • Air Conditioning and Refrigeration operations [except as covered by Condition II(l) of this permit], including seventeen (17) cooling towers/chillers; fifty (50) fume hoods and periscopes, and photographic development chemicals;
  • Eight small natural gas-fired hot water boilers: One (1) Emission Unit –2.68 MMBTU/hr; Two (2) Emission Units –2.50 MMBTU/hr; One (1) Emission Unit -2.41 MMBTU/hr; One (1) Emission Unit – 1.34 MMBTU/hr; Two (2) Emission Units – 0.5 MMBTU/hr;  and One (1) Emission Unit – 0.24 MMBTU/hr; 
  • Eight (8) natural gas-fired water heaters: Three (3) units rated at 1.2 MMBTU/hr each, one (1) unit rated at 0.42 MMBTU/hr, two (2) units rated at 0.39 MMBTU/hr and one (1) unit rated at 0.75 MMBTU/hr, one (1) unit rated at 0.8 MMBTU/hr -  all less than 1.6 MMBTU/hr and equal to or less than 0.3 MMBTU/hr; and
  • Five (5) natural gas-fired water heaters: Two (2) unit rated at 0.19 MMBTU/hr each, , two (2) units rated at 0.078 MMBTU/hr each, and one (1) unit rated at 0.04 MMBTU/hr - all less than 0.3 MMBTU/hr.

EMISSIONS SUMMARY:

The following is an estimate of overall potential emissions from the facility:

FACILITY-WIDE EMISSIONS SUMMARY

Criteria Pollutants

Potential Emissions
(tons per year)

Oxides of Sulfur (SOx)

2.46

Oxides of Nitrogen (NOx)

88.22

Total Particulate Matter, including condensables (PM Total)

7.56

Volatile Organic Compounds (VOC)

5.73

Carbon Monoxide (CO)

44.33

Total Hazardous Air Pollutants (Total HAP)

1.62

American University has the potential to emit 88.22 tons per year (TPY) of oxides of nitrogen (NOx). The value for this criteria pollutant exceeds the major source threshold in the District of Columbia of 25 TPY of NOx (a precursor for ozone). No other pollutants have the potential to be emitted in excess of the other major source thresholds in the District. Because potential emissions of NOx exceed the relevant major source threshold, pursuant to 20 DCMR 300.1(a), the source is subject to Chapter 3 and must obtain an operating permit in accordance with that regulation and Title V of the federal Clean Air Act.

The Department of Energy and Environment (DOEE) has reviewed the permit application and related documents and has made a preliminary determination that the applicant meets all applicable air quality requirements promulgated by the U.S. Environmental Protection Agency (EPA) and the District. Therefore, draft permit No. 013-R3 has been prepared.

The application, the draft permit, and all other materials submitted by the applicant [except those entitled to confidential treatment under 20 DCMR 301.1(c)] considered in making this preliminary determination are available for public review during normal business hours at the offices of the Department of Energy and Environment, 1200 First Street NE, 5th Floor, Washington DC 20002. Copies of the draft permit and related Fact Sheet and Statement of Basis are available at in the attachments section below.

A public hearing on this permitting action will not be held unless DOEE has received a request for such a hearing within 30 days of the publication of this notice. Interested parties may also submit written comments on the permitting action.


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