ASTi is the actual VOC content of stain i, in kilograms VOC per liter (pounds VOC per gallon), as delivered to the applicator during the actual production day
SSTi is the total amount of stain i, in liters (gallons), delivered to the applicator during the actual production day
NR 422.125(3)(b)1.1. Determine the overall control efficiency needed to demonstrate compliance daily using Equation 3. where:
R is the overall efficiency of the control system needed to demonstrate compliance on a daily basis, expressed as a percentage
C is the highest VOC content of all coatings subject to this paragraph on any given day in kilograms per kilogram of coating solids (pounds per pound of coating solids), as applied
E is the emission limitation applicable to the coating in kilograms per kilogram of coating solids (pounds per pound of coating solids), as applied
NR 422.125(3)(b)2.2. Document that the value of C in Equation 3 is obtained from the VOC and solids content of the as applied finishing material. NR 422.125(3)(b)4.4. Demonstrate compliance when R as determined under subd. 1. is greater than or equal to the overall efficiency of the control device determined under subd. 3. NR 422.125(4)(4) Application technology. After September 1, 1996, an owner or operator of a wood furniture manufacturing facility may use conventional air spray to apply finishing materials only under any of the following conditions: NR 422.125(4)(a)(a) When applying finishing materials that have an as applied VOC content no greater than 1.0 kilogram per kilogram of solids (1.0 pound per pound of solids). NR 422.125(4)(b)(b) When applying final touch-up and repair finishing materials. NR 422.125(4)(c)(c) When using a control device to meet the applicable requirements of this section. NR 422.125(4m)(4m) Cleaning material work practices. Beginning on March 1, 2013, the owner or operator of a facility subject to this subsection shall do all of the following: NR 422.125(4m)(a)(a) Use cleaning materials containing no more than 8.0% by weight VOC for cleaning spray booth components other than conveyors, continuous coaters and their enclosures, or metal or plastic filters. NR 422.125(4m)(c)(c) Collect all VOC-containing cleaning material used to clean spray guns and spray gun lines in a container and keep the container covered except when adding or removing material. NR 422.125(4m)(d)(d) Control emissions of VOC-containing cleaning material from washoff operations by doing both of the following: NR 422.125(4m)(d)1.1. Equipping the tank used for washoff operations with a cover and keeping the cover closed whenever the tank is not being used. NR 422.125(4m)(d)2.2. Minimizing dripping by tilting or rotating the part to drain as much cleaning material as possible into the tank. NR 422.125(4m)(e)(e) Use strippable spray booth materials containing no more than 0.8 pound of VOC per pound of solids, as applied. NR 422.125(5)(5) Initial compliance certification and notification requirements. NR 422.125(5)(a)(a) Emission limitations. Any owner or operator subject to this section shall submit a written notification to the department within 60 days after the compliance deadline in sub. (2), or upon changing the method of operation when such a change would result in a change in the emission limitations applicable under sub. (2). The notification shall contain: NR 422.125(5)(a)2.2. The name or identification number of all finishing operations subject to this section and the applicable emission limitations. NR 422.125(5)(a)3.3. Certification that all wood furniture finishing operations are in compliance with the applicable emission limitations. NR 422.125(5)(b)(b) Emission averaging. Any owner or operator of a wood furniture manufacturing facility achieving compliance with the emission limitations of sub. (2) by means of the emission averaging method allowed under sub. (3) (a) shall notify the department by 60 days prior to the compliance deadline in sub. (2), upon startup of a new finishing operation, or upon changing the method of compliance to sub. (3) (a). The notification shall contain:
