Draft Air Quality Permit 6506-R1 - U.S. General Services Administration

Friday, April 20, 2018

PUBLIC NOTICE

Draft Air Quality Permit 6506-R1, U.S. General Services Administration, Operation of an existing 800 kWe diesel-fired emergency generator set at 400 Maryland Avenue SW

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 an air quality permit (No. 6506-R1) to the U.S. General Services Administration operate an 800 kWe emergency generator set powered by a 1,252 hp diesel-fired engine at 400 Maryland Avenue SW, Washington DC. The contact person for facility is Calvert M. Jones, Supervisory Building Engineer, at (202) 205-2279. The applicant’s mailing address is 400 Maryland Avenue SW Washington, DC 20024.

Emissions:

Maximum emissions from the 800 kW emergency generator set, assuming 500 hours per year of operation, are expected to be as follows: 

                                                  

Maximum Annual Emissions

Pollutant

(tons/yr)

Total Particulate Matter (PM Total)

0.22

Sulfur Dioxide (SO2)

                                    0.0038

Nitrogen Oxides (NOx)

7.51

Volatile Organic Compounds (VOC)

0.22

Carbon Monoxide (CO)

1.72

The proposed emission limits for the equipment are as follows:

a.   Visible emissions shall not be emitted into the outdoor atmosphere from this generator, 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].

Note that 20 DCMR 606 is subject to an EPA-issued call for a State Implementation Plan (SIP) revision (known as a “SIP call”) requiring the District to revise 20 DCMR 606. See “State Implementation Plans: Response to Petition for Rulemaking; Restatement and Update of EPA’s SSM Policy Applicable to SIPs; Findings of Substantial Inadequacy; and SIP Calls To Amend Provisions Applying to Excess Emissions During Periods of Startup, Shutdown and Malfunction”, 80 Fed. Reg. 33840 (June 12, 2015). It is likely that this federal action will result in changes to the requirements of 20 DCMR 606.  Any such changes, once finalized in the DCMR, will supersede the language of Condition II(a) as stated above.

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]

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

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 permit.
