Section NR 465.05 - Work practice standards(1) WORK PRACTICE IMPLEMENTATION PLAN. The owner or operator of an affected source shall prepare and maintain a written work practice implementation plan that defines environmentally desirable work practices for each wood furniture manufacturing operation and addresses each of the work practice standards in subs. (2) to (12). The plan shall be developed no more than 60 days after the applicable compliance date in s. NR 465.055. The written work practice implementation plan shall be available for inspection by the department upon request. If the department determines that the work practice implementation plan does not adequately address each of the topics specified in subs. (2) to (12), or that the plan does not include sufficient mechanisms for ensuring that the work practice standards are being implemented, the department may require that the owner or operator of the affected source modify the plan. Revisions or modifications to the plan do not require a revision of a permit issued under ch. NR 407.(2) OPERATOR TRAINING COURSE. The owner or operator of an affected source shall train all personnel, including contract personnel, who are involved in finishing, gluing, cleaning or washoff operations, use of manufacturing equipment or implementation of the requirements of this subchapter. Personnel hired on or after the compliance date of the standard shall be trained upon hiring. Personnel hired before the compliance date shall be trained within 6 months of the compliance date of the standard. All personnel shall be given refresher training annually. The owner or operator of an affected source shall maintain a copy of the training program with the work practice implementation plan. The training program shall include, at a minimum, all of the following: (a) A list of all current personnel by name and job description that are required to be trained.(b) An outline of the subjects to be covered in the initial and refresher training for each position or group of personnel.(c) Lesson plans for courses to be given at the initial and the annual refresher training that include, at a minimum, appropriate application techniques, appropriate cleaning and washoff procedures, appropriate equipment setup and adjustment to minimize finishing material usage and overspray and appropriate management of cleanup wastes.(d) A description of the methods to be used to demonstrate and document that personnel have successfully completed the initial and refresher training.(3) INSPECTION AND MAINTENANCE PLAN. The owner or operator of an affected source shall prepare and maintain, with the work practice implementation plan, a written leak inspection and maintenance plan for all pumps, valves, flanges and other equipment used to transfer or apply coatings, adhesives or organic HAP solvents that specifies all of the following: (a) An inspection schedule which specifies a minimum visual inspection frequency of once per month.(b) Methods for documenting the date and results of each inspection and any repairs that were made.(c) The timeframe between identifying the leak and making the repair, which adheres, at a minimum, to the following schedule: 1. A first attempt at repair shall be made no later than 5 calendar days after the leak is detected.2. Final repairs shall be made within 15 calendar days after the leak is detected, unless the leaking equipment is to be replaced by a new purchase, in which case repairs shall be completed within 3 months.(4) CLEANING AND WASHOFF SOLVENT ACCOUNTING SYSTEM. The owner or operator of an affected source shall develop an organic HAP solvent accounting form to record all of the following:(a) The quantity and type of organic HAP solvent used each month for washoff and cleaning operations.(b) The number of pieces washed off, and the reason for the washoff.(c) The quantity of spent organic HAP solvent generated from each washoff and cleaning operation each month, and whether it is reused onsite in a process other than cleaning or washoff or disposed of outside of the facility boundaries.(5) CHEMICAL COMPOSITION OF CLEANING AND WASHOFF SOLVENTS. The owner or operator of an affected source may not use solvents for cleaning or washoff operations that contain any of the pollutants listed in Table 3 in this subchapter in concentrations 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).(6) SPRAY BOOTH CLEANING. The owner or operator of an affected source may not use compounds containing more than 8.0 % by weight of VOC for cleaning spray booth components other than conveyors, continuous coaters and their enclosures, or metal or plastic filters. If the spray booth coating or other protective material used to cover the booth is being replaced, the owner or operator may not use more than 1.0 gallon of organic HAP solvent per booth to prepare the surface of the booth prior to applying the booth coating.(7) STORAGE REQUIREMENTS. The owner or operator of an affected source shall store finishing, gluing, cleaning and washoff materials in closed containers.(8) APPLICATION EQUIPMENT REQUIREMENTS. The owner or operator of an affected source may use conventional air spray guns to apply finishing materials only under any of the following circumstances: (a) To apply finishing materials that have a VOC content no greater than 1.0 kg VOC/kg solids (1.0 lb VOC/lb solids), as applied.(b) For touchup and repair under any of the following conditions:1. The touchup and repair occurs after completion of the finishing operation.2. The touchup and repair occurs after the application of stain and before the application of any other type of finishing material, and the materials used for touchup and repair are applied from a container that has a volume of no more than 2.0 gallons.(c) When the spray gun is aimed and triggered automatically.(d) When emissions from the finishing application station are directed to a control device.(e) When the cumulative total usage of finishing materials applied with conventional air spray guns is no more than 5.0 % of the total gallons of finishing material used during that semiannual period.(f) When the conventional air gun is used to apply stain on a part for which it is technically or economically infeasible to use any other spray application technology. The owner or operator of an affected source shall demonstrate technical or economic infeasibility by submitting to the department a videotape, a technical report or other documentation that supports the affected source's claim of technical or economic infeasibility. The owner or operator shall use one or both of the following criteria to support a claim that no other spray application technology is technically or economically feasible: 1. The production speed is too high or the part shape is too complex for one operator to coat the part and the application station is not large enough to accommodate an additional operator.2. The excessively large vertical spray area of the part makes it difficult to avoid sagging or runs in the stain.(9) LINE CLEANING. The owner or operator of an affected source shall pump or drain all organic HAP solvent used for line cleaning into a container which shall be kept covered except when actively adding solvent to or removing solvent from the container.(10) GUN CLEANING. The owner or operator of an affected source shall collect all organic HAP solvent used to clean spray guns into a container which shall be kept covered except when actively adding solvent to or removing solvent from the container.(11) WASHOFF OPERATIONS. The owner or operator of an affected source shall control emissions from washoff operations by doing both of the following: (a) Equipping any tank used for washoff operations with a cover and keeping the cover closed whenever the tank is not being used.(b) Minimizing dripping by tilting or rotating the part to drain as much solvent as possible.(12) FORMULATION ASSESSMENT PLAN FOR FINISHING OPERATIONS.(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:1. Identifies VHAP from the list presented in Table 4 in this subchapter that are being used in finishing operations by the affected source.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. 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). (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: 1. The exceedance is no more than 15.0 % above the baseline level.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.3. The affected source is in compliance with ch. NR 400 to 499 for the VHAP.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.(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.(d) If, after November 1998, the owner or operator of an affected source uses a VHAP of potential concern listed in Table 5 in this subchapter for which a baseline level has not been previously established, the baseline level shall be established as the de minimis level provided in Table 5 in this subchapter for that chemical. The owner or operator shall track the annual usage of each VHAP of potential concern identified in this paragraph 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). If usage of the VHAP of potential concern exceeds the de minimis level listed in Table 5 in this subchapter for that chemical, the owner or operator shall provide an explanation to the department that documents the reason for exceedance of the de minimis level. If the explanation is not one of those listed in par. (b), the owner or operator shall follow the procedures in par. (c).Wis. Admin. Code Department of Natural Resources NR 465.05
