§ 52.057 INDUSTRIAL CLASS USERS; FORMULAS.
   The amounts to be recovered annually from each industrial class user shall be determined in accordance with the three formulas set out below.
   (A)   (1)   For flow related recovery, the formula for each industrial class user shall be:
 
RF = FC x (User Flow-Annually/Design Flow-Annually) x (1/30 years)
 
      (2)   Definition of terms is:
         (a)   RF: industrial cost recovery based on flow; and
         (b)   FC: capital costs which are flow related.
   (B)   (1)   For BOD related recovery, the formula for each industrial class user shall be:
 
RB = BC x (User Loading - Pounds (Based on 200 mg/l as minimum)/Design Capacity - Pounds) x (1/30 years)
 
      (2)   Definition of terms is:
         (a)   RB: industrial cost recovery based on BOD loading; and
         (b)   BC: capital costs which are strength related.
   (C)   (1)   For suspended solids related recovery, the formula for each industrial class user shall be:
 
RS = SC x (User Loading - Pounds (based on 250 mg/l as minimum)/Design Capacity - Pounds) x (1/30 years)
 
      (2)   Definition of terms is:
         (a)   RS: industrial cost recovery based on suspended solids loading; and
         (b)   SC: capital costs which are strength related.
   (D)   Until such time as a unit process cost study is developed, the amounts of capital costs used in the formulas in divisions (A) through (C) above shall be 40% of total capital costs for flow, and 30% each for BOD and suspended solids.
