9-4-5: INDUSTRIAL COST RECOVERY:
   A.   Industrial Cost Recovery Required:
      1.   Each industrial user shall pay that portion of any State grant which has been obtained by the Village for the financing of the construction of wastewater treatment works allocable to the treatment of the wastewater from such user. Such user's share shall not include an interest component.
      2.   Each year during the industrial cost recovery period, each industrial user of the treatment works shall pay the cost recovery amount determined by subsection B or C of this section for such industry, divided by the recovery period. Where an industry is connected to a public sewer after the startup of the facilities constructed under a State grant, such industry shall only pay its portion of the State grant for each billing period remaining in the recovery period. Such industry will not be required to pay for those billing periods of the recovery period prior to connection to a public sewer.
   B.   Industrial Cost Recovery Charge: The charge for industrial cost recovery shall be based on a charge per unit volume of normal strength process flow. Normal strength flow shall be waste strength less than or equal to two hundred milligrams per liter (200 mg/L) BOD and two hundred fifty milligrams per liter (250 mg/L) SS. The industrial cost recovery charge will be computed as follows:
      1.   Estimate the State grant amount allocable to those treatment units used to process dry weather sewage flow (which includes industrial waste flows).
      2.   Divide the allocable State grant amount by the industrial cost recovery period.
      3.   Determine the average annual design flow volume by multiplying the daily design flow average of four hundred thousand (400,000) gallons per day by three hundred sixty five (365) days per year. (The result is 146,000,000 gallons per year.)
      4.   Divide the annual allocable grant amount determined in subsection B2 of this section by the average annual design flow volume of one hundred forty six million (146,000,000) gallons. (Ord. 1999-11, 10-4-1999)
      5.   The resulting charge as provided in section 9-4-13 of this chapter will be charged all industrial users having a process waste flow.
   C.   Total Charge To Industrial User:
      1.   The total industrial cost recovery charge for each billing period shall be determined by multiplying a user's industrial process flow volume discharged during the billing period by the amount provided in section 9-4-13 of this chapter. (Ord. 1999-11, 10-4-1999; amd. 2011 Code)
      2.   Industrial process flow volume shall be determined by measurement or estimation of all water flow through industrial plant processes. In the absence of meter readings, process flow shall be estimated by using the following formula:
         PF = TWF - DF - CF
 
Where:
PF
=
Process flow for billing period
TWF
=
Total water flow for billing period from meter reading, plus estimates of flow from private wells, if any
DF
=
Domestic flow from employees estimated by multiplying the average number of man shifts worked for the billing period by an allowance of 25 gallons per man shift worked
CF
=
Flow consumed or otherwise not returned to the sewer
 
      3.   If, in the opinion of the Village Clerk, the Village interest would be served by making the above estimation on an annual basis, then the Clerk may elect to negotiate with each industry a percentage of the total water flow to estimate the process flow each billing period.
   D.   Length Of Industrial Cost Recovery Period: The industrial cost recovery period shall be equal to the useful life of the treatment works which shall be thirty (30) years from 1979.
   E.   Payments And Billing: Industrial cost recovery charges to industrial users shall be included with the regular billing for sewer use charges as specified in this chapter.
   F.   Adjustment Of Charge:
      1.   If, at any time, during the industrial cost recovery period, an industry begins discharging wastes with strengths greater than two hundred milligrams per liter (200 mg/L) BOD and two hundred fifty milligrams per liter (250 mg/L) SS, a study shall be made under the direction of the Village Board to revise the industrial cost recovery charge to include a high waste strength surcharge as well as a process flow volume charge. The revised charge factors shall be applied to process flow volume and measured waste strength quantities in excess of normal.
      2.   If there is an expansion or upgrading of the treatment works utilizing a State grant, each existing industrial user's share shall be adjusted accordingly.
   G.   No Charge For Unused Or Unreserved Capacity: An industrial user's portion of any State grant shall not include any portion of the grant amount allocable to unused or reserved capacity.
   H.   Commitment For Increased Use: An industrial user's portion of any State grant shall include allowance for the cost of any firm commitment to the Village for any increased use by such user.
   I.   Retained Amounts:
      1.   Disposition: Eighty percent (80%) 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 Federal Act and the State. The Village, prior to commitment of the retained amounts, shall obtain written approval of the Illinois Environmental Protection Agency for any expansion or reconstruction. The remainder of the retained amount may be used for such expenditures as the Village deems appropriate.
      2.   Investment: Pending use, the grantee shall invest the retained amounts for reconstruction and expansion in:
         a.   Obligations of the U.S. government;
         b.   Obligations guaranteed as to principal and interest by the U.S. government or any agency thereof; or
         c.   Shall deposit such amounts in accounts fully collateralized by obligations of the U.S. government or by obligation fully guaranteed as to principal and interest by the U.S. government or any agency thereof.
   J.   Records, Billing, Expenditures: The Village Treasurer shall maintain the necessary records for determination of user share of the cost and shall provide the billing and collection services as required, and be responsible for the investment and expenditure of all monies collected for industrial cost recovery in accordance with subsections H and I of this section.
   K.   Monitoring Required: The Superintendent of Public Works shall maintain a program of monitoring industrial user discharges as the Village Board deems necessary; provided, that any major contributing industry shall be monitored no less than twelve (12) times annually. (Ord. 1999-11, 10-4-1999)
