Sec. 463.11  Specialized definitions.

    For the purpose of this subpart:
    (a) The ``average process water usage flow rate'' of a contact 
cooling and heating 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 contact cooling and heating water is the 
sum of the ``average process water usage flow rates'' for the contact 
cooling and heating processes.
    (b) The ``volume of process water used per year'' is the volume of 
process water that flows through a contact cooling and heating water 
process and comes in contact with the plastic product over a period of 
one year.
