Each industrial user shall pay that portion of any federal grant, such grant obtained by the City of Mendota for the financing of the construction of wastewater treatment works, allocable to the treatment of the industrial waste from such user as required by Section 204(b) of the Act and subsequent rules, regulations and guidelines. The user's share shall not include an interest component.
A. 
An industrial user's portion of any federal grant shall be based upon the volume and strength of wastewater discharged to the wastewater treatment works of the City of Mendota based upon the following parameters:
(1) 
Volume. This value equals the average daily rate of water consumption as determined by the consumption records of the past year minus 20 gallons per employee per eight-hour shift for domestic waste or, where water consumption does not reflect the actual quantity of wastewater tributary to the treatment works from such user, then the average daily flow as recorded in the control manhole minus 20 gallons per employee per eight-hour shift for domestic waste.
(2) 
Biochemical oxygen demand (BOD). This value equals the average daily pounds of BOD in the wastewater minus 0.05 pound of BOD per employee per eight-hour shift (for domestic waste).
(3) 
Suspended solids (SS). This value equals the average daily pounds of suspended solids in the wastewater from such user minus 0.04 pound of suspended solids per employee per eight-hour shift (for domestic waste).
(4) 
Ammonia-nitrogen (NH3-N). This value equals the average daily pounds of ammonia-nitrogen in the wastewater from such user minus 0.0269 pound of ammonia-nitrogen per employee per eight-hour shift (for domestic waste).
B. 
Section 245-72 herein outlines the requirements for measurement of industrial waste flow and strength.
The dollar unit cost shall be determined as follows:
A. 
Proportion the project grant cost to major plant categories.
B. 
Proportion the grant cost associated with each major plant category to volume, BOD5, SS and NH3-N.
C. 
Compute the ICR rates by dividing the annual plant design loading into the grant amount allocated to volume, BOD5, SS and NH3-N. This results in the ICR rate for the thirty-year industrial cost recovery period. With additional divisions, the yearly and daily rate can be developed.

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I).
The cost to be recovered from an industrial user (C1) where the volume of average daily use exceeds the number of employees times 20 gallons per day shall be computed by the following formula:
C1 = (Volume) - ($211 + $9.50) (0.062383) (BOD5) + ($14.70) (0.00834) (SS) + ($16.40) (0.00834) (NH3-N)
Where:
C1 = industrial waste cost recovery amount per quarter to industrial user.
Volume = Million cubic feet of wastes discharged per quarter after adjustment for domestic wastes (§ 245-54A).
$211 = Volume ICR per million cubic feet per quarter.
$9.50 = BOD5 ICR rate per 1,000 pounds per quarter.
$14.70 = SS ICR rate per 1,000 pounds per quarter.
$16.40 = NH3-N ICR rate per 1,000 pounds per quarter.
0.0062383 = Constant.
BOD5 = Average annual 5-day biochemical oxygen demand in mg/l.
SS = Average annual suspended solids concentration in mg/l.
NH3-N = Average annual ammonia-nitrogen concentration in mg/l.
Each year during the industrial cost recovery period, each industrial user of the treatment works shall pay the cost recovery amount determined by § 245-56. Where an industry is connected to a public sewer after the start-up of the facilities constructed under a state grant, such industry shall only pay its portion of the state grant for each quarter remaining in the recovery period. Such industry will not be required to pay for those quarters of the recovery period prior to connection to a public sewer.
The industrial cost recovery period shall be equal to the useful life of the treatment works, which shall be 30 years beginning May 1, 1980.
For the purpose of industrial cost recovery, the year shall be divided into quarterly periods, said periods to begin on the first day of May, August, November and February, and all industrial users of the City of Mendota shall pay the cost as determined by § 245-56 for industrial cost recovery charges. Bills shall be sent out by the City Clerk within 10 days after the end of the period for which service has been supplied, and such charge shall be payable within 30 days after rendition thereof, and in the event such bills are not paid within said 30 days, a service charge of 10% shall be added thereto for each thirty-day period after the date of the quarterly bill, provided service is continued during this period. An overdue notice will be sent out 30 days after the bills are due and payable.
In the event the charges for industrial cost recovery are not paid within 90 days after the rendition of that bill, then such charges shall be deemed and are hereby declared to be delinquent, and thereafter such delinquent charge shall constitute a lien upon a real estate for which such sewer services were supplied. The City Clerk is hereby directed each quarter to file sworn statements showing such delinquencies in the office of the Recorder of Deeds of LaSalle County, Illinois, and the filing of such statements shall be deemed notice of a lien for the payment of such charges for industrial cost recovery. If the delinquency in the payment of the recovery cost continues for the period of more than 90 days, the sewer service shall be discontinued.
The initial payment made by an industrial user which is connected to the public sewer after the start-up of the treatment works constructed with a state grant shall be made by the next scheduled due date as defined in § 245-59 and shall be equal to the proportional share (based on days of service) of one quarterly charge as determined by § 245-56.
If there is a change in the strength and/or volume introduced into the treatment works by an industrial user as determined by the previous year's records, the City of Mendota may adjust the industrial waste cost recovery charge.
If there is an expansion for upgrading of the treatment works utilizing a state grant, each existing industrial user's share shall be adjusted accordingly.
An industrial user's portion of any state grant shall not include any portion of the grant amount allocable to unused or reserved capacity.
An industrial user's portion of any state grant shall include allowance for the cost of any firm commitment to the City of Mendota for any increased use by such user.
The City of Mendota shall retain 50% of the amounts recovered from industrial users. The remainder, together with any interest earned thereon, shall be returned to the State of Illinois Anti-Pollution Fund on an annual basis.
Eighty percent of the retained amounts, together with interest earned thereon, shall be used solely for the eligible costs of the expansion or reconstruction of treatment works associated with the project and necessary to meet the requirements of the state grant. The City of Mendota, prior to commitment of the retained amounts, shall obtain written approval of the IEPA for any expansion or reconstruction. The remainder of the retained amounts may be used for such expenditures as the City of Mendota deems appropriate.
Pending use, the grantee shall invest the retained amounts for reconstruction and expansion in:
A. 
Obligations of the United States Government; or
B. 
Obligations guaranteed as to principal and interest by the United States Government or any agency thereof; or
C. 
Deposits in accounts fully collateralized by obligations of the United States Government or by obligations fully guaranteed as to principal and interest by the United States Government or any agency thereof, whichever has the highest rate of interest at the time of investment.
The City Clerk shall maintain the necessary records for determination of the industrial user share of the cost and shall provide the billing and collection services as required by §§ 245-54 and 245-58 and Article VIII.
The City Treasurer shall be responsible for the investment and expenditure of all moneys collected for industrial cost recovery in accordance with Article VIII.
The Superintendent shall maintain a program of monitoring industrial user discharges as the Superintendent deems necessary, provided that any major contributing industry shall be monitored no less than 12 times annually. All other minor industrial users shall be monitored at such frequency as deemed necessary by the Superintendent for determination of the industrial cost recovery charge for that industrial user or the user may be assessed cost recovery payments on the basis of estimated discharges, provided that such waste discharge is compatible with the wastewater treatment process.
A. 
Major industrial waste dischargers, within 90 days of the date of notification by the City of Mendota, shall install metering devices and samplers and manholes as required to determine waste characteristics discharged to the public sewers.
B. 
Flow metering devices, installed in monitoring manholes or services lines, will be required for measurement of the volume of waste discharged to the sewers when volumes cannot otherwise be determined from metered water consumption records. This determination shall be made by the City of Mendota.
C. 
The industry shall install and maintain waste samplers and hire an approved laboratory to complete waste testing when directed by the City of Mendota. Waste sampling and testing shall be completed by the discharger as often as may be deemed necessary by the City of Mendota, and all certified test results shall be forwarded to the City of Mendota. The City shall reserve the right to sample and test all discharges at any time and bill the dischargers for all involved costs. The City of Mendota shall establish discharge loads and industrial waste cost recovery charges based on either or both tests and this shall be binding as a basis for industrial waste cost recovery charges.
