For each project which services a user as defined in Section 949.03 and which is constructed by or in conjunction with the City 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 of thirty years as defined in Section 949.01(d) which produces the annual industrial cost recovery rate. The annual rate is then divided by the respective annual capacity of the Wastewater Treatment Plant (WWTP) 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 yr.) | ||||
(2) | Annual ICR rate = ICR charge | |||
Annual Capacity of sewers into WWTP (100 cf) per 100 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 of subsections B. through D. hereof by the ICR period of thirty years to obtain individual ICR rates. | |||
(3) | Divide individual ICR rates by respective capacities of WWTP. | |||
A. | Annual ICR total rate | = ICR charge per 100 cf for normal | ||
Annual WWTP capacity (100 cf) | strength or less discharge | |||
B. | Annual ICR BOD rate | = ICR charge per 100 lbs. BOD | ||
Annual WWTP capacity (100 lbs. BOD) | in excess of 300 mg/l | |||
C. | Annual ICR SS rate | = ICR charge per 100 lbs. SS | ||
Annual WWTP capacity (100 lbs. SS) | in excess of normal limits | |||
D. | Annual ICR "other" rate | = ICR charge per other unit in | ||
Annual WWTP capacity (units of other) | excess of normal limits | |||
