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)(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:
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.
