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.
