NR 422.15(9)(a) (a) Store all VOC-containing cleaning materials and shop towels used for cleaning in closed containers.

NR 422.15(9)(b) (b) Ensure that storage containers used for VOC-containing materials are kept closed at all times except when depositing or removing material.

NR 422.15(9)(c) (c) Convey VOC-containing cleaning materials in closed containers or pipes.

NR 422.15(9)(d) (d) Minimize spills of VOC-containing cleaning materials.

NR 422.15(9)(e) (e) Minimize emissions of VOC 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.

NR 422.15(10) (10) Compliance schedule and certification.

NR 422.15(10)(a) (a) Compliance schedule. The owner or operator of a miscellaneous metal parts and products facility described under sub. (1) (am) and located in Kewaunee, Manitowoc, or Walworth county that commenced construction before June 1, 2022, shall comply with the applicable requirements of this section by November 28, 2022.

NR 422.15(10)(b) (b) Certification. No later than 60 days after the compliance deadline specified under par. (a), the owner or operator of a miscellaneous metal parts and products facility described in par. (a) shall submit to the department written certification that all affected miscellaneous metal parts and products coating operations are in compliance with the applicable requirements of this section. Any such facility that is required to have an operation permit under ch. NR 407 shall submit to the department a permit application or a permit revision or renewal application that meets the application requirements under s. NR 407.05 to meet this certification requirement, except that no application shall be required for a source operating under a general operation permit or a registration operation permit issued under s. NR 407.10 or 407.105.

NR 422.151(1) (1) Applicability. Beginning on June 1, 2022, this section applies to all coating line application areas, conveyors, flashoff areas, drying areas, forced-air driers, and ovens of any industry categorized under the 2-digit major groups of 33 to 39 as described in the Standard Industrial Classification Manual, 1987, incorporated by reference under s. NR 484.05 (1), that are involved in the surface coating of miscellaneous metal parts and products at a facility that meets all of the following criteria:

NR 422.151(1)(a) (a) The facility is located in any of the following areas:
