VOC Content Limitations for Coatings Used in Plastic Parts Coating – Low VOC Coatings
[kilogram/liter (pounds/gallons) of coating, excluding water and exempt compounds listed in s. NR 400.02 (162) (a), as applied] NR 422.084 NoteNote: The VOC content limits for the coating and application types under Table 1C rows 1. a. to k. apply to any coating that does not meet the definitions for the specific coatings listed under Table 1C rows 2. a. to 5. h.
NR 422.084(4)(b)(b) If the low-VOC coatings 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 90 percent for VOC. NR 422.084(5)(5) Application methods. An owner or operator of an affected facility under this section, except for a facility that uses add-on control equipment as described under sub. (4) (b), shall use one or a combination of the following application methods for the affected coating operations: NR 422.084(5)(h)(h) Other coating application methods that are capable of achieving a transfer efficiency equivalent to or better than achieved by high-volume, low-pressure spraying and are approved by the department in writing. NR 422.084(6)(6) Add-on control equipment requirements. An owner or operator that uses add-on control equipment as described under sub. (4) (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 422.084(7)(7) Work practices for coating-related activities. The owner or operator of an affected facility under this section shall do all of the following for coating-related activities: NR 422.084(7)(a)(a) Store all VOC-containing coatings, thinners, and coating-related waste materials in closed containers. NR 422.084(7)(b)(b) Ensure that mixing and storage containers used for VOC-containing coatings, thinners, and coating-related waste materials are kept closed at all times, except when depositing or removing those materials. NR 422.084(7)(c)(c) Minimize spills of VOC-containing coatings, thinners, and coating-related waste materials. NR 422.084(7)(d)(d) Convey VOC-containing coatings, thinners, and coating-related waste materials from one location to another in closed containers or pipes. NR 422.084(8)(8) 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 422.084(8)(a)(a) Store all VOC-containing cleaning materials and used shop towels in closed containers. NR 422.084(8)(b)(b) Ensure that storage containers used for VOC-containing materials are kept closed at all times except when depositing or removing those materials. NR 422.084(8)(c)(c) Convey VOC-containing cleaning materials from one location to another in closed containers or pipes. NR 422.084(8)(e)(e) Minimize emissions of VOCs during cleaning of coating application, storage, mixing, and conveying equipment by ensuring that cleaning is performed without atomizing any VOC-containing cleaning material and that the used material is captured and contained.
