PART 463--PLASTICS MOLDING AND FORMING POINT SOURCE CATEGORY--Table of Contents
 
Sec. 463.1  Applicability.

    (a) This part applies to any plastics molding and forming process 
that discharges or may discharge pollutants to waters of the United 
States 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 commonly recognized 
processes such as extrusion, molding, coating and laminating, 
thermoforming, calendering, casting, foaming, cleaning, and finishing.
    (b) 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 regulation 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 the effluent limitations guidelines and standards for the plastics 
molding and forming category in this part.
    (c) Processes that coat a plastic material onto a substrate may fall 
within the definition of electroplating and metal finishing as defined 
in 40 CFR parts 413 and 433. These coating processes are excluded from 
the effluent limitations guidelines and standards for the electroplating 
and metal finishing point source categories and are subject to the 
plastics molding and forming regulation in this part.

    (d) Coating of plastic material onto a formed metal substrate is 
also covered by the plastics molding and forming effluent limitations 
guidelines and standards and is not covered by the specific metal 
forming guidelines such as aluminum forming (40 CFR part 467), copper 
forming (40 CFR part 468), and nonferrous metals forming (40 CFR part 
471). However, the plastics molding and forming effluent limitations 
guidelines and standards in this part apply only to the coating process; 
the metal forming operations are subject to the specific metal forming 
regulation.
    (e) Research and development laboratories that produce plastic 
products using a plastics molding and forming process are subject to the 
effluent limitations guidelines and standards in this part 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 the plastics 
molding and forming regulation in this part to plastics molding and 
forming processes at research and development laboratories.
    (f) Chemical and thermal reticulation processes for polyurethane 
foam are not subject to the effluent limitations guidelines and 
standards in this part. Water used in those processes is not considered 
to be process water as defined in this regulation. Processes used to 
further mold or form the reticulated foam are subject, however, to this 
regulation if they discharge process water.
    (g) Processes used to regenerate cellulose and to produce a product 
(e.g., rayon) from the regenerated cellulose are not subject to the 
effluent limitations guidelines and standards in this part. Processes 
that mold or form cellulose derivatives (e.g., cellulose acetate) are 
subject to the effluent limitations guidelines and standards in this 
part if they discharge process water.
