NR 422.084 History History: CR 20-088: cr. Register May 2022 No. 797, eff. 6-1-22; correction in (10) (a) 1. made under s. 13.92 (4) (b) 14., Stats., Register May 2022 No. 797.

NR 422.085 NR 422.085 Leather coating.

NR 422.085(1) (1) Applicability. Effective February 1, 1987, this section applies to coating applications at leather coating facilities which are either of the following:

NR 422.085(1)(a) (a) Located in the county of Kenosha, Milwaukee, Ozaukee, Racine, Washington, or Waukesha, and which have maximum theoretical emissions of VOC from the facility greater than or equal to 25 tons per year.

NR 422.085(1)(b) (b) Located in the county of Door, Kewaunee, Manitowoc, Sheboygan, or Walworth, and which have maximum theoretical emissions of VOC from the facility greater than or equal to 100 tons per year.

NR 422.085(2) (2) Emission limitations. No owner or operator of a leather coating facility may cause, allow or permit the emission of any VOCs from coating applications in excess of 18.6 kilograms per 100 square meters (38.0 pounds per 1000 square feet) of coated product calculated on a daily average basis.

NR 422.085(3) (3) Compliance requirements and schedules. The owner or operator of a leather coating facility shall comply with the requirements of sub. (4) and s. NR 425.03 (1), (8), and (9).

NR 422.085(4) (4) Reporting and recordkeeping.

NR 422.085(4)(a) (a) To determine compliance with the leather coating VOC emission limit in this section, the facility shall maintain daily coating usage and leather production records in a format approved by the department. Reporting, recordkeeping and access to these records shall be in accordance with ss. NR 439.03 to 439.05.

NR 422.085(4)(b) (b) The daily VOC emission rate shall be determined by the following equation:

where:

c is the daily average VOC emission rate

a is the total amount of VOCs emitted during the day

b is the prorated surface area of leather coated during the day, where:

- See PDF for table

di is the total area of the ith batch of hides coated during the day

ei is the ratio of actual VOC emissions resulting from coating any portion of the ith batch of hides during the day to the total predicted VOC emissions resulting from all coating of the entire ith batch

NR 422.085(4)(c) (c) The facility shall measure the surface area of each piece of leather coated with a mechanism initially calibrated for minimum accuracy to the Turner Korrect Machine or Sawyer Measurement systems. The average surface area per coated piece of leather may be used for a batch of leather provided that the average is based on a minimum of 500 pieces. Otherwise, the facility average surface area per coated leather piece shall be used. In no case may the total area allocated to production over all days from a piece of leather exceed the average area for that leather.

NR 422.09 NR 422.09 Automobile and light-duty truck manufacturing.

NR 422.09(1) (1) Applicability.

NR 422.09(1)(a) (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.

NR 422.09(1)(b) (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.

NR 422.09(1)(c) (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.

NR 422.09(1)(d) (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).

NR 422.09(2) (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:

NR 422.09(2)(a) (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.

NR 422.09(2)(b) (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.

NR 422.09(2)(d) (d) After December 31, 1985, 0.34 kilograms per liter of coating (2.8 pounds per gallon), excluding water, from a topcoat coating line.
