Air Quality Operating Permit - Board of Regents at the National Museum of the American Indian


Notice Requesting Public Comment on Draft Title V and Chapter 2 Air Quality Operating Permit for the Smithsonian Institution, Board of Regents at the National Museum of the American Indian

Notice is hereby given that the Smithsonian Institution, Board of Regents has applied for a Title V air quality permit pursuant to the requirements of Title 20 of the District of Columbia Municipal Regulations, Chapters 2 and 3 (20 DCMR Chapters 2 and 3) to operate three 8.165 million BTU per hour boilers, one paint booth, one emergency generator, and miscellaneous other smaller equipment at the National Museum of the American Indian facility located at 4th Street & Independence Avenue SW, Washington, DC. The contact person for the facility is John Michael Bixler, Facility Zone Manager at (202) 633-2573.

The Smithsonian Institution National Museum of the American Indian has the potential to emit 22.24 tons per year (TPY) of nitrogen oxides (NOx), 7.81 TPY of sulfur dioxide (SO2), 1.83 TPY of particulate matter (PM), 1.94 TPY of volatile organic compounds (VOC), and 13.21 TPY of carbon monoxide.

Under normal maximum operating conditions for determination of the potential emissions of the facility, the facility would have the potential to emit more than 25 TPYof NOx (the District’s major source threshold) if each of the three 8.165 million BTU per hour boilers were to operate 8,760 hours per year firing No. 2 fuel oil or diesel fuel. However, in order to avoid Non-Attainment New Source Review (NNSR) program applicability, the Smithsonian Institution requested a permit limit of 144 hours of operation per 12-month rolling period using No. 2 fuel oil or diesel fuel (with unlimited hours of operation using natural gas) for each of the three 8.165 million BTU per hour boilers at the time the Chapter 2 permits were issued. The Chapter 3 permitting process is being used in this case to make these limits federally enforceable and enforceable as a practical matter.

Description and Emission Information for Unit being Permitted for the First Time:

One Cross-draft Paint Booth (SSB-1), used primarily for painting and finishing museum exhibits:

Maximum annual potential emissions from the unit are expected to be as follows:





Particulate Matter (PM) (Total)1


Volatile Organic Compounds (VOC)


The proposed emission limits for the paint booth are as follows:

A.  No person shall discharge into the atmosphere more than fifteen (15) pounds of volatile organic compound (VOC) emissions in any one (1) day, nor more than three pounds (3 lb.) in any one (1) hour, from any combination of articles, machines, units, equipment, or other contrivances at a facility, unless the uncontrolled VOC emissions are reduced by at least ninety percent (90%) overall capture and control efficiency. [20 DCMR 700.2]

B.  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]

C.  Visible emissions shall not be emitted into the outdoor atmosphere from the paint spray booth. [20 DCMR 107 and 606]

D.  No chemical strippers containing methylene chloride (MeCl) shall be used for paint stripping at the facility. [20 DCMR 201]

The District Department of the Environment (DDOE) 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 Title V permit #040 has been prepared.

The application, the draft Title V 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 District Department of the Environment, 1200 First Street NE, 5th Floor, Washington DC 20002. Copies of the draft permit and related fact sheet are available at http://ddoe.dc.gov.

A public hearing on this permitting action will not be held unless DDOE 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.  Hearing requests or comments should be directed to Stephen S. Ours, DDOE Air Quality Division, 1200 First Street NE, 5th Floor, Washington DC 20002.  Questions about this permitting action should be directed to Abraham T. Hagos at (202) 535-1354 or [email protected].  Comments or hearing requests submitted after September 29, 2014 will not be accepted.
