NR 422.128(2)(b)3.3. Adhesives or adhesive primers used in medical equipment manufacturing operations. NR 422.128(2)(b)6.6. Processes using polyester bonding putties to assemble fiberglass parts at fiberglass boat manufacturing facilities and at other reinforced plastic composite manufacturing facilities. NR 422.128(2)(b)7.7. Processes using adhesives and adhesive primers that are supplied to the manufacturer in containers with a net volume of 16 ounces or less or a net weight of one pound or less. NR 422.128(3)(a)(a) Except as specified under par. (b), the owner or operator of an affected adhesive or adhesive primer application process located at an affected facility under this section shall use the low-VOC adhesives or adhesive primers that meet the VOC content limits in Table 2C for the affected adhesive or adhesive primer application processes. For general adhesive application processes using an adhesive to bond dissimilar substrates, the highest VOC emission limitation applies. Table 2C
VOC Content Limitations for Adhesives and Adhesive Primers
[gram/liter (pounds/gallons) of adhesive or adhesive primer, excluding water and exempt compounds listed in s. NR 400.02 (162) (a), as applied] NR 422.128 NoteNote: The VOC content limits for the adhesive and application types under Table 2C rows 1. a. to g. apply to any adhesive or adhesive primer that does not meet the definitions for the specific coatings listed under Table 2C rows 2. a. to 3. d.
NR 422.128(3)(b)(b) If the low-VOC adhesives or adhesive primers that meet the VOC content limits required under par. (a) are not used at an affected facility, the owner or operator shall use add-on control equipment that achieves a minimum overall emission reduction efficiency of 85 percent for VOC. NR 422.128(4)(4) Application methods. An owner or operator of an affected facility under this section shall use one or a combination of the following application methods: NR 422.128(4)(d)(d) Roll coating or hand application, including non-spray application methods similar to hand or mechanically powered caulking gun, brush, or direct hand application. NR 422.128(4)(h)(h) Other adhesive application methods that are capable of achieving a transfer efficiency equivalent to or better than that achieved by high-volume, low-pressure spraying and are approved by the department in writing. NR 422.128(5)(5) Add-on control equipment requirements. An owner or operator that uses add-on control equipment as described under sub. (3) (b) shall comply with the applicable monitoring, testing, and recordkeeping requirements specified under ss. NR 439.04 (5) (e), 439.055, and 439.075. NR 422.128(6)(6) Work practices for adhesive application processes. The owner or operator of an affected facility under this section shall do all of the following for adhesive or adhesive primer application processes: NR 422.128(6)(a)(a) Store all VOC-containing adhesives, adhesive primers, and process-related waste materials in closed containers. NR 422.128(6)(b)(b) Ensure that mixing and storage containers used for VOC-containing adhesives, adhesive primers, and process-related waste materials are kept closed at all times, except when depositing or removing those materials. NR 422.128(6)(c)(c) Minimize spills of VOC-containing adhesives, adhesive primers, and process-related waste materials. NR 422.128(6)(d)(d) Convey VOC-containing adhesives, adhesive primers, and process-related waste materials from one location to another in closed containers or pipes. NR 422.128(7)(7) Cleaning material work practices. The owner or operator of an affected facility under this section shall do all of the following for cleaning materials: NR 422.128(7)(a)(a) Store all VOC-containing cleaning materials and used shop towels in closed containers.
