Section NR 283.015 - Applicability(1) This chapter applies to any plastics molding and forming process that discharges or may discharge pollutants to waters of the state or that introduces pollutants into a publicly owned treatment works. Plastics molding and forming processes include processes that blend, mold, form, or otherwise process plastic materials into intermediate or final plastic products. They include but are not limited to extrusion, molding, coating and laminating, thermoforming, calendering, casting, foaming, cleaning, and finishing.(2) Plastics molding and forming processes used by plastics resin manufacturers to process crude intermediate plastic material for shipment off-site are excluded from this chapter and are subject to chs. NR 235 and 280. Plastics molding and forming processes used by plastic resin manufacturers to process crude intermediate plastic materials, which are further processed on-site into intermediate or final plastic products in molding and forming processes, are subject to this chapter.(3) Processes that coat a plastic material onto a substrate are subject to the requirements of this chapter. Although these processes may fall within the definition of electroplating and metal finishing as defined in chs. NR 260 and 261, they are excluded from the requirements of chs. NR 260 and 261.(4) Coating of plastic material onto a formed metal substrate is subject to this chapter and is not covered by the specific metal forming guidelines in chs. NR 253, 257 and 273. However, the plastics molding and forming effluent limitations and standards in this chapter apply only to the coating process; the metal forming operations are subject to the specific metal forming regulation.(5) Research and development laboratories that produce plastic products using a plastics molding and forming process are subject to this chapter if the plastics molding and forming process discharges process water. The mass of plastic product produced in the plastics molding and forming process is not considered when determining the applicability of this chapter to plastics molding and forming processes at research and development laboratories.(6) Chemical and thermal reticulation processes for polyurethane foam are not subject to this chapter. Water used in those processes is not considered to be process water as defined in this chapter. However, processes used to further mold or form the reticulated foam are subject to this chapter if they discharge process water.(7) Processes used to regenerate cellulose and to produce a product from the regenerated cellulose are not subject to this chapter. Processes that mold or form cellulose derivatives are subject to this chapter if they discharge process water.Wis. Admin. Code Department of Natural Resources NR 283.015
