(a) Charges and Fees. The City shall adopt charges and fees to provide for the cost of administration of the pretreatment program including fees for: monitoring, inspections and surveillance procedures; permit applications; filing appears; and reviewing accidental discharge procedures and construction. Fees shall be as follows:
(1) Wastewater Discharge Permit Fee. For the purposes provided for in Chapter 939, there is hereby levied a fee to be paid by every user required to obtain a wastewater discharge permit to discharge into the sanitary sewer system as set forth below. Such fees shall be payable upon the application for and/or the renewal of the permit.
(Ord. 1992-183. Passed 10-27-92.)
A. Insignificant User | $75.00 |
(Ord. 2008-099. Passed 11-11-08.) | |
B. Minor Significant User | 100.00 |
C. Major Significant, Non-categorical User | 150.00 |
D. Major Significant, Categorical User | 200.00 |
(2) Inspection Fee. There is hereby levied a fee to be paid by each user whose facility is inspected by City personnel for the purpose of determining compliance with Chapter 939, Codified Ordinances. Inspection fees shall be established by the Director of Public Service and shall be payable and collectible from time to time as determined by said Director, or his designate.
(3) Wastewater Rules and Regulations Charge. There is hereby levied a charge to be paid by each user who wishes to obtain a copy of the City's wastewater rules and regulations. The charge is determined to be ten dollars ($10.00) per copy to cover the printing costs, administrative costs, etc. This charge shall also cover any additions, changes or deletions to the regulations.
(b) Sewer Surcharge. A sewer surcharge shall be fixed by the City and levied for any person, firm or corporation whose premises are serviced by a sanitary sewer connection and discharges wastes other than normal sewage into the sewerage system.
(1) Surcharge formulas. Surcharges shall be based on the applicable constituents of the wastewater as follows:
A. Total suspended solids; and/or
B. C.B.O.D., five days at 20 degrees Centigrade; and/or
C. C.O.D.; and/or
D. Phosphorus; and/or
E. Oil and grease
Whenever the wastes are ruled acceptable to wastewater treatment and the wastewater contains suspended solids, C.B.O.D. and/or C.O.D. and/or phosphorus and/or oil and grease in excess of normal sewage, the excess shall be subjected to a surcharge derived in accordance with the following formulas:
SC = ((SS-225) x F x 8.34 x CS) + ((CBOD-185) x F x 8.34 x CB) = F x 8.34 x ((SS-225) x CS + (CBOD-185) x CB)
SC = Surcharge based on average daily flow.
SS = Total suspended solids in wastes as discharged in mg/l.
225 = Suspended solids concentrations in normal sewage in mg/l.
F = Flow in millions of gallons per day of wastes as discharged.
CS = Cost to treat one pound of suspended solids in cents per pound. Total operating cost attributable to total pounds of suspended solids/total pounds of suspended solids removed.
CBOD = Total C.B.O.D. in wastes as discharged in mg/l.
185 = C.B.O.D. concentration in normal sewage in mg/l.
CB = Cost to treat one pound of C.B.O.D. in cents per pound. Total operating cost attributable to C.B.O.D./total pounds of C.B.O.D. removed.
or
SC = ((SS-225) x F x 8.34 x CS) + ((COD-250) x F x 8.34 x CC) = F x 8.34 x ((SS-225) x CS + (COD-250) x CC)
COD = Total C.O.D. in wastes as discharged in mg/l.
250 = C.O.D. concentration in normal sewage in mg/l.
CC = Cost to treat one pound of C.O.D. in cents per pound. Total operating cost attributable to C.O.D./total pounds of C.O.D. removed.
or
SC = (P-8) x F x 8.34 x CP
P = Total phosphorus in wastes as discharged in mg/l.
8 = Total phosphorus concentration in normal sewage in mg/l.
CP = Cost to treat one pound of phosphorus in cents per pound. Total operating cost attributable to phosphorus/total pounds of phosphorus removed.
or
SC = (OG-80) x F x 8.34 x COG
OG = Total oil and grease in wastes as discharged in mg/l.
80 = Total oil and grease concentration in normal sewage in mg/l.
COG = Cost to remove one pound of oil and grease in cents per pound. Total operating cost attributable to oil and grease/total pounds of oil and grease removed.
(2) Use of C.B.O.D. and C.O.D. analyses. Whenever a waste cannot be analyzed by a C.B.O.D. test the C.O.D. result shall prevail in calculating a surcharge. Whenever both testing methods are possible, the City shall determine which analysis shall apply in computing the surcharge based on which will provide the higher surcharge.
(3) Annual review of strength surcharge. On or before March 1 of each year the strength surcharge for the POTW for the previous year will be reviewed. The cost to treat the C.B.O.D., C.O.D., oil and grease, suspended solids and phosphorus shall be based on the total operating cost of the sewerage works. Increases or decreases in the cost of treating and disposing of excess amounts of C.B.O.D., C.O.D., oil and grease, suspended solids and phosphorus shall be reflected on a proportionate basis in the strength surcharge on the basis of cost per pound.
