Current through June 24, 2024
(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.
