(a) Equipping any tank used for washoff operations with a cover and keeping the cover closed whenever the tank is not being used.
NR 465.05(11)(b)
(b) Minimizing dripping by tilting or rotating the part to drain as much solvent as possible.
NR 465.05(12)
(12) Formulation assessment plan for finishing operations. NR 465.05(12)(a)(a) The owner or operator of an affected source shall prepare and maintain with the work practice implementation plan a formulation assessment plan that does all of the following:
NR 465.05(12)(a)1.
1. Identifies VHAP from the list presented in Table 4 in this subchapter that are being used in finishing operations by the affected source.
NR 465.05(12)(a)2.
2. Establishes a baseline level of usage by the affected source for each VHAP identified in
subd. 1. The baseline usage level shall be the highest annual usage from 1994, 1995 or 1996, for each VHAP identified in
subd. 1., or from another year approved by the department if annual usage data for those years is not available or if the affected source was not in operation during those years. For formaldehyde, the baseline level of usage shall be based on the amount of free formaldehyde present in the finishing material when it is applied. For styrene, the baseline level of usage shall be an estimate of unreacted styrene, which shall be calculated by multiplying the amount of styrene monomer in the finishing material, when it is applied, by a factor of 0.16. For sources using a control device to reduce emissions, an adjusted usage may be calculated based on the overall control efficiency of the control system.
NR 465.05(12)(a)3.
3. Tracks the annual usage of each VHAP identified in
subd. 1. that is present in amounts that require inclusion on an MSDS in accordance with the occupational safety and health administration hazard communication standard in
29 CFR part 1910 Subpart Z, incorporated by reference in
s. NR 484.03 (1).
NR 465.05(12)(b)
(b) If, after November 1998, the annual usage of the VHAP identified under
par. (a) 1. exceeds the baseline level
established
under
par. (a) 2., the owner or operator of the affected source shall provide a written notification to the department that describes the amount of the increase and explains the reasons for exceedance of the baseline level. Any of the following explanations relieve the owner or operator from further action, unless the affected source is not in compliance with any state regulations or requirements for that VHAP:
NR 465.05(12)(b)2.
2. Usage of the VHAP is below the de minimis level presented in Table 4 in this subchapter for that VHAP. For sources using a control device to reduce emissions, an adjusted usage based on the overall control efficiency of the control system may be calculated and used to demonstrate that the source does not exceed the de minimis level in Table 4 in this subchapter.
NR 465.05(12)(b)4.
4. The source of the pollutant is a finishing material with a VOC content of no more than 1.0 kg VOC/kg solids (1.0 lb VOC/lb solids), as applied.
NR 465.05(12)(c)
(c) If none of the explanations in
par. (b) are the reason for the increase, the owner or operator shall confer with the department to discuss the reason for the increase and whether there are practical and reasonable technology-based solutions for reducing the usage. The evaluation of whether a technology is reasonable and practical shall be based on cost, quality and marketability of the product, whether the technology is being used successfully by other wood furniture manufacturing operations, or other criteria mutually agreed upon by the department and owner or operator. If there are no practical and reasonable solutions, the owner or operator need take no further action. If there are solutions, the owner or operator shall develop a plan to reduce usage of the pollutant to the extent feasible. The plan shall address the approach to be used to reduce emissions, a timetable for implementing the plan and a schedule for submitting notification of progress.
