Sec. 463.31  Specialized definitions.



    For the purpose of this subpart:

    (a) The ``average process water usage flow rate'' of a finishing 

water process in liters per day is equal to the volume of process water 

(liters) used per year by a process divided by the number of days per 

year the process operates. The ``average process water usage flow rate'' 

for a plant with more than one plastics molding and forming process that 

uses finishing water is the sum of the ``average process water usage 

flow rates'' for the finishing processes.

    (b) The ``volume of process water used per year'' is the volume of 

process water that flows through a finishing water process and comes in 

contact with the plastics product over a period of one year.
