Sec. 463.21  Specialized definitions.



    For the purpose of this subpart:

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

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 cleaning water is the sum of the ``average process water usage flow 

rates'' for the cleaning processes.

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

process water that flows through a cleaning process and comes in contact 

with the plastic product over a period of one year.
