Notice of Public Comment Period - Draft Air Quality Permit 6554-R3, WMATA - Shepherd Parkway Bus Facility
PUBLIC NOTICE
Notice of Public Comment Period - Draft Air Quality Permit 6554-R3, Washington Metropolitan Area Transit Authority (WMATA), Shepherd Parkway Bus Facility
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. 6554-R3) to the Washington Metropolitan Area Transit Authority (WMATA) to operate one existing automotive paint spray booth at the Shepherd Parkway Bus Facility located at 2 DC Village Lane SW, Washington DC. The contact person for the facility is Claire Fox, Deputy Chief, EMAC at (301) 618-7508 or [email protected].
Emissions Estimate:
WMATA estimates that the maximum expected emissions of volatile organic compounds (VOC) from the automotive paint spray booth will not exceed 0.18 ton per year based on the types of materials currently used in the booth and estimated maximum use rates of these materials. Based on more conservative assumptions about the materials used and maximum theoretical usage of the unit AQD has estimated that the maximum potential to emit from the unit will not exceed 3.12 tons per year of VOC.
The proposed emission limits are as follows:
a. No chemical strippers containing methylene chloride (MeCl) shall be used for paint stripping at the facility. [20 DCMR 201.1]
b. The Permittee shall not use or apply to a motor vehicle, mobile equipment, or associated parts and components, an automotive coating with a VOC regulatory content calculated in accordance with the methods specified in this permit that exceeds the VOC content requirements of Table I below. [20 DCMR 718.3]

*VOC regulatory limit as applied = weight of VOC per volume of coating (prepared to manufacturer’s recommended maximum VOC content, minus water and non-VOC solvents)
c. Each cleaning solvent present at the facility shall not exceed a VOC content of twenty-five (25) grams per liter (twenty-one one-hundredths (0.21) pound per gallon), calculated in accordance with the methods specified in this permit, except for [20 DCMR 718.4]:
1. Cleaning solvent used as bug and tar remover if the VOC content of the cleaning solvent does not exceed three hundred fifty (350) grams per liter (two and nine-tenths (2.9) pounds per gallon), where usage of cleaning solvent used as bug and tar remover is limited as follows:
A. Twenty (20) gallons in any consecutive twelve-month (12) period for an automotive refinishing facility and operations with four hundred (400) gallons or more of coating usage during the preceding twelve (12) calendar months;
B. Fifteen (15) gallons in any consecutive twelve-month (12) period for an automotive refinishing facility and operations with one hundred fifty (150) gallons or more of coating usage during the preceding twelve (12) calendar months; or
C. Ten (10) gallons in any consecutive twelve-month (12) period for an automotive refinishing facility and operations with less than one hundred fifty (150) gallons of coating usage during the preceding twelve (12) calendar months;
2. Cleaning solvents used to clean plastic parts just prior to coating or VOC-containing materials for the removal of wax and grease provided that non-aerosol, hand-held spray bottles are used with a maximum cleaning solvent VOC content of seven hundred eighty (780) grams per liter and the total volume of the cleaning solvent does not exceed twenty (20) gallons per consecutive twelve-month (12) period per automotive refinishing facility;
3. Aerosol cleaning solvents if one hundred sixty (160) ounces or less are used per day per automotive refinishing facility; or
4. Cleaning solvent with a VOC content no greater than three hundred fifty (350) grams per liter may be used at a volume equal to two-and-one-half percent (2.5%) of the preceding calendar year’s annual coating usage up to a maximum of fifteen (15) gallons per calendar year of cleaning solvent.
d. If, on the container of an automotive coating, or a label or sticker affixed to the container, or in sales, advertising, technical, or product literature, a representation is made that indicates that the coating meets the definition of or is recommended for use for more than one (1) of the coating categories listed in Condition (b) (relating to coating VOC content limits), then the lowest applicable VOC content limit shall apply. [20 DCMR 718.8]
e. The Permittee may not possess either of the following [20 DCMR 718.9]:
1. An automotive coating that is not in compliance with Condition (b) (relating to coating VOC content limits); and
2. A cleaning solvent that does not meet the requirements of Condition (c) (relating to cleaning solvent VOC content limits).
f. 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]
f. Visible emissions shall not be emitted into the outdoor atmosphere from the paint booth. [20 DCMR 201.1, 20 DCMR 606, and 20 DCMR 903.1]
