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.
