939.03 DETERMINATION OF ICR RATES.
For each project which services a user as defined in Section 939.02 and which is constructed by or in conjunction with the Agency and for which USEPA financial assistance is used and industrial cost recovery is required, the final grant amount shall be divided by the ICRS period (30 years) as defined in Section 931.01 (18) which produces the annual industrial cost recovery rate. The annual rate is then divided by the respective annual capacity of the treatment works to produce an incremental charge per unit of usage. The method for developing ICR rates for the two general types of improvements is as follows:
(a) Collection System Improvements, Except Infiltration/Inflow Correction or Treatment.
(1) Final grant amount
——————————— = Annual ICR rate
ICR period (30 years)
(2) Annual ICR rate
—————————————————————— = ICR charge per 1000 cf
Annual Capacity of sewers into WWTP (1000 cf)
(b) Wastewater Treatment Plant Improvements.
(1) Allocate final grant by facility constructed
A. Flow
B. BOD removal
C. SS removal
D. Other pollutant removal or treatment related grant
(2) Divide the total grant amount and the individual facility grant amounts B. through D. inclusive by ICR period (30 years) to obtain individual ICR rates.
(3) Divide individual ICR rates by respective capacities of WWTP.
A. Annual ICR Total rate ICR charge per 1000 cf for
—————————————— = normal strength or less
—————————————— = normal strength or less
Annual WWTP capacity (1000 cf) discharge
B. Annual ICR BOD rate ICR charge per 100 lbs
———————————————— = BOD in excess of 210
———————————————— = BOD in excess of 210
Annual WWTP capacity (100 lbs BOD) mg/l
C. Annual ICR SS rate ICR charge per 100 lbs
———————————————— = SS in excess of 240
———————————————— = SS in excess of 240
Annual WWTP capacity (100 lbs SS) mg/l
D. Annual ICR "other" rate ICR charge per
———————————————— = unit other in
———————————————— = unit other in
Annual WWTP capacity (units of other) excess of normal
