Current through Register Vol. 48, No. 28, July 12, 2024
a)
				Applicability
1) This Subpart CL applies to
				any plastics molding and forming process that introduces or may introduce
				process wastewater pollutants into a POTW. Plastics molding and forming
				processes include processes that blend, mold, form, or otherwise process
				plastic materials into intermediate or final plastic products. They include
				commonly recognized processes such as extrusion, molding, coating and
				laminating, thermoforming, calendering, casting, foaming, cleaning, and
				finishing.
2) Plastics molding and
				forming processes (e.g., extrusion and pelletizing) used by plastics resin
				manufacturers to process crude intermediate plastic material for shipment
				off-site are excluded from this Subpart and regulated under the organic
				chemicals, plastics, and synthetic fibers category. 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 plastics products in molding and forming processes, are
				controlled by this Subpart CL.
3)
				Processes that coat a plastic material onto a substrate may fall within the
				definition of electroplating and metal finished as defined in Subpart N or AH.
				These coating processes are excluded from the electroplating and metal
				finishing point source categories and are subject to this Subpart CL.
4) Coating of plastic material onto a formed
				metal substrate is also covered by this Subpart and is not covered by the
				specific metal forming rules such as aluminum forming, copper forming, and
				nonferrous metals forming (Subparts CP, CQ, and CT, respectively). This Subpart
				CL applies only to the coating process; the metal forming operations are
				subject to the specific metal forming rules.
5) Research and development laboratories that
				produce plastic products using a plastics molding and forming process are
				subject to this Subpart CL 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 Subpart CL 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 Subpart CL. Water used
				in those processes is not considered to be process water as defined in
				40 CFR
				463.2 (2003), incorporated by reference in
				subsection (b). Processes used to further mold or form the reticulated foam are
				subject, however, to this Subpart if they discharge process water.
7) Processes used to regenerate cellulose and
				to produce a product (e.g., rayon) from the regenerated cellulose are not
				subject to the limitations and standards in this Subpart. Processes that mold
				or form cellulose derivatives (e.g., cellulose acetate) are subject to this
				Subpart CL if they discharge process water.
