subch. I of ch. NR 465 Subchapter I — Wood Furniture Manufacturing Operations

NR 465.01 NR 465.01 Applicability; purpose.

NR 465.01(1) (1) Applicability.

NR 465.01(1)(a) (a) This subchapter applies to each facility that is engaged, either in part or in whole, in the manufacture of wood furniture or wood furniture components and that is located at a plant site that is a major source of hazardous air pollutants.

NR 465.01(1)(b) (b) An incidental wood furniture manufacturer shall maintain purchase or usage records demonstrating the source meets the criteria specified in s. NR 465.02 (33), but the source is not subject to any other provisions of this subchapter.

NR 465.01(1)(c) (c) A source that qualifies as an area source under this paragraph is not subject to any provisions of this subchapter other than those in this paragraph. For subds. 1. and 2., finishing materials, adhesives, cleaning solvents and washoff solvents used for wood furniture or wood furniture component manufacturing operations shall account for at least 90% of annual HAP emissions at the plant site, and if the plant site has HAP emissions that do not originate from the listed materials, the owner or operator shall keep any records necessary to demonstrate that the 90% criterion is being met. A source that initially relies on the limits and criteria specified in subd. 1., 2. or 3. to become an area source, but subsequently exceeds the relevant limit, without first obtaining and complying with other limits that keep its potential to emit hazardous air pollutants below major source levels, becomes a major source and shall comply thereafter with all applicable provisions of this subchapter starting on the applicable compliance date in s. NR 465.055. Nothing in this paragraph is intended to preclude a source from limiting its potential to emit through other appropriate mechanisms. A source qualifies as an area source for the purposes of this subchapter if the criteria in one of the following subdivisions are met:

NR 465.01(1)(c)1. 1. The owner or operator of the source uses no more than a total of 250 gallons per month, for every month, of coating, adhesive, cleaning material and washoff materials at the source, including materials used for source categories other than wood furniture, but excluding materials used in routine janitorial or facility grounds maintenance, personal uses by employees or other persons, the use of products for the purpose of maintaining motor vehicles operated by the facility, the use of toxic chemicals contained in intake water used for processing or noncontact cooling and intake air used either as compressed air or for combustion. The owner or operator shall maintain records for 5 years of the total gallons of coating, adhesive, cleaning material and washoff material used each month, and upon request submit the records to the department.

NR 465.01(1)(c)2. 2. The owner or operator of the source uses no more than 3,000 gallons per rolling 12-month period, for every 12-month period, of coating, adhesive, cleaning material and washoff material at the source, including materials used for source categories other than wood furniture, but excluding materials used in routine janitorial or facility grounds maintenance, personal uses by employees or other persons, the use of products for the purpose of maintaining motor vehicles operated by the facility, the use of toxic chemicals contained in intake water used for processing or noncontact cooling and intake air used either as compressed air or for combustion. The owner or operator of the source shall maintain records of the total gallons of coating, adhesive, cleaning material and washoff material used each month and the total gallons used each previous month, and upon request submit the records to the department. The owner or operator shall keep monthly records beginning no less than one year before the compliance date specified in s. NR 465.055 and maintain the records for 5 years.

NR 465.01(1)(c)3. 3. The source emits no more than 4.5 Mg (5 tons) of any one HAP per rolling 12-month period and no more than 11.4 Mg (12.5 tons) of any combination of HAP per rolling 12-month period, and at least 90% of the plantwide HAP emissions per rolling 12-month period are associated with the manufacture of wood furniture or wood furniture components. The owner or operator shall maintain records for 5 years that demonstrate that annual emissions do not exceed these levels, including monthly usage records and certified product data sheets for all finishing material, adhesive, cleaning material and washoff material, and any other records necessary to document emissions from source categories other than wood furniture. The owner or operator shall submit the records to the department upon request.

NR 465.01(1)(d) (d) This subchapter does not apply to research or laboratory equipment for which the primary purpose is to conduct research and development into new processes and products, where the equipment is operated under the close supervision of technically trained personnel and is not engaged in the manufacture of products for commercial sale in commerce, except in a de minimis manner.

NR 465.01(1)(e) (e) The owner or operator of an affected source shall comply with the requirements of ch. NR 460, according to the applicability of ch. NR 460 to the sources, as identified in ch. NR 460 Appendix JJ.

NR 465.01(1)(f) (f) Reconstructed affected sources are subject to the requirements for new affected sources. The costs associated with the purchase and installation of air pollution control equipment are not considered in determining whether the facility has been reconstructed, unless the control equipment is part of the process. Additionally, the costs of retrofitting and replacement of equipment that is installed specifically to comply with this subchapter are not considered reconstruction costs.

NR 465.01 Note Note: An example of when control equipment is part of a process is where the equipment is used to recover product or raw material. An example of costs for equipment replacement which would not be considered reconstruction costs is the replacement of storage tanks, mix equipment and transfer lines to accommodate conversion to waterborne coatings where the purpose of the conversion is to comply with this subchapter.

NR 465.01(2) (2) Purpose. This subchapter is adopted under ss. 285.27 (2) and 285.65, Stats., to establish emission standards for hazardous air pollutants for wood furniture and wood furniture component manufacturing operations.

NR 465.01 Note Note: This subchapter is based on the federal regulations contained in 40 CFR part 63 Subpart JJ, created Dec. 7, 1995, as last revised on Dec. 28, 1998.

NR 465.02 Note Note: Airless and air assisted airless spray technologies are not conventional air spray because the coating is not atomized by mixing it with compressed air. Electrostatic spray technology is also not considered conventional air spray because an electrostatic charge is employed to attract the coating to the workpiece.

NR 465.02(20) (20) “Day” means a period of 24 consecutive hours beginning at midnight local time, or beginning at a time consistent with a facility’s operating schedule.
