Section NR 422.09 - Automobile and light-duty truck manufacturing(1) APPLICABILITY. (a) This section applies to the application areas, flashoff areas, and ovens of automobile and light-duty truck manufacturing plants involved in prime, topcoat, and final repair coating of metallic front end and main body parts at any facility located in the county of Kenosha, Milwaukee, Ozaukee, Racine, Sheboygan, Washington, or Waukesha if VOC emissions from the prime, topcoat, and final repair coating and related cleaning activities at the facility, before consideration of controls, equal or exceed 3 tons per year on a 12 consecutive month rolling basis.(b) Subsections (2) to (5) apply to the coating operations described in par. (a) at any automobile and light-duty truck manufacturing facility located in the county of Brown, Calumet, Dane, Dodge, Door, Fond du Lac, Jefferson, Kewaunee, Manitowoc, Outagamie, Rock, Walworth, and Winnebago if VOC emissions from all coating operations described in par. (a) at the facility, before consideration of controls, equal or exceed 6.8 kilograms (15 pounds) in any one day. (c) Subsections (2) to (5) apply to coating operations as described in par. (a) at any automobile and light-duty truck manufacturing facility not subject to par. (a) or (b) if total VOC emissions from the facility, before consideration of controls, equal or exceed 100 tpy. (d) Subsections (2) to (5) do not apply to the coating of wheels, trunk interiors, steering columns, or nonmetallic parts; sealers; nonpriming anti-rust coatings; or processes, coatings, or inks described in s. NR 422.03(5) and (7).(2) EMISSION LIMITATIONS-ENAMELS. No owner or operator of an automobile surface coating line which, prior to January 1, 1979, used an enamel coating system, may cause, allow or permit the emission of any VOCs in excess of:(a) After December 31, 1983, 0.14 kilograms per liter of coating (1.2 pounds per gallon), excluding water, from an electrodeposition prime coat or equivalent coating line.(b) After December 31, 1982, 0.34 kilograms per liter of coating (2.8 pounds per gallon), excluding water, from a spray primer-surfacer coating line.(d) After December 31, 1985, 0.34 kilograms per liter of coating (2.8 pounds per gallon), excluding water, from a topcoat coating line.(e) After December 31, 1982, 0.58 kilograms per liter of coating (4.8 pounds per gallon), excluding water, from any final repair coating line.(3) EMISSION LIMITATIONS-LACQUERS. No owner or operator of an automobile surface coating line which, prior to January 1, 1979, used a lacquer coating system, may cause, allow or permit the emission of any VOCs in excess of: (b) After December 31, 1982, 0.14 kilograms per liter of coating (1.2 pounds per gallon), excluding water, from an electrodeposition prime coat coating line.(d) After December 31, 1986, 0.34 kilograms per liter of coating (2.8 pounds per gallon), excluding water, from a spray primer-surfacer coating line.(g) After December 31, 1986, 0.34 kilograms per liter of coating (2.8 pounds per gallon), excluding water, from a topcoat coating line.(i) After December 31, 1986, 0.58 kilograms per liter of coating (4.8 pounds per gallon), excluding water, from any final repair coating line.(4) EMISSION LIMITATIONS-TRUCKS. No owner or operator of a light-duty truck surface coating line may cause, allow or permit the emission of any VOCs in excess of: (b) After December 31, 1982, 0.14 kilograms per liter of coating (1.2 pounds per gallon), excluding water, from an electrodeposition prime coat coating line.(d) After December 31, 1987, 0.34 kilograms per liter of coating (2.8 pounds per gallon), excluding water, from a spray primer-surfacer coating line.(f) After December 31, 1987, 0.34 kilograms per liter of coating (2.8 pounds per gallon), excluding water, from a topcoat coating line.(g) After December 31, 1982, 0.58 kilograms per liter of coating (4.8 pounds per gallon), excluding water, from any final repair coating line.(5) EMISSION RATE AVERAGING. Each emission limit in this section may be interpreted as a weighted daily average, if specified in an approved compliance plan. The emission limits are referenced to waterborne coatings conventionally applied. Any coating line which achieves an equivalent emission rate per unit area coated shall be deemed in compliance.(6) WORK PRACTICES. Beginning on March 1, 2013, the owner or operator of a facility subject to this section shall do all of the following: (a) Minimize VOC emissions from cleaning of storage, mixing and conveying equipment.(b) Develop and implement a work practice plan to minimize VOC emissions from cleaning and purging of equipment associated with all coating operations. The plan shall specify practices and procedures for the following operations, at a minimum: 3. Flushing of coating systems.4. Cleaning of spray booth grates.5. Cleaning of spray booth walls.6. Cleaning of spray booth equipment.7. Cleaning of external spray booth areas.Wis. Admin. Code Department of Natural Resources NR 422.09
