Sec. 463.2  General definitions.

    In addition to the definitions set forth in 40 CFR part 401, the 
following definitions apply to this part:
    (a) ``Plastics molding and forming'' is a manufacturing process in 
which plastic materials are blended, molded, formed, or otherwise 
processed into intermediate or final products.
    (b) ``Process water'' is any raw, service, recycled, or reused water 
that contacts the plastic product or contacts shaping equipment surfaces 
such as molds and mandrels that are, or have been, in contact with the 
plastic product.
    (c) ``Contact cooling and heating water'' is process water that 
contacts the raw materials or plastic product for the purpose of heat 
transfer during the plastics molding and forming process.
    (d) ``Cleaning water'' is process water used to clean the surface of 
an intermediate or final plastic product or to clean the surfaces of 
equipment used in plastics molding and forming that contact an 
intermediate or final plastic product. It includes water used in both 
the detergent wash and rinse cycles of a cleaning process.
    (e) ``Finishing'' water is processed water used to remove waste 
plastic material generated during a finishing process or to lubricate a 
plastic product during a finishing process. It includes water used to 
machine or to assemble intermediate or final plastic products.
    (f) ``Plastic material'' is a synthetic organic polymer (i.e., a 
thermoset polymer, a thermoplastic polymer, or a combination of a 
natural polymer and a thermoset or thermoplastic polymer) that is solid 
in its final form and that was shaped by flow. The material can be 
either a homogeneous polymer or a polymer combined with fillers, 
plasticizers, pigments, stabilizers, or other additives.
    (g) ``Crude intermediate plastic material'' is plastic material 
formulated in an on-site polymerization process.
    (h) ``Mass of pollutant that can be discharged'' is the pollutant 
mass calculated by multiplying the pollutant

concentration times the average process water usage flow rate.
