MISSOURI 63141 314-432-8070 Board of Public Works and Safety CITY OF JEFFERSONVILLE City/County Building Jeffersonville, IN 47130 RE: Wastewater Flows and Loadings Dear Sirs/and Madam: r Enclosed please find a table and graphs that illustrates the flows and loadings to the wastewater L, treatment facility for the period of May 1, 1994 through April 30, 1997. The loadings have been calculated by using the monthly average influent flow in million gallon per day (mgd). Total Suspended Solids (TSS), and Biochemical Oxygen Demand (BOD) were calculated in milligrams per liter (mg/l), for example: [ [ flow (mgd) x mg/l x 8.34(conversion factor) = lbs. As outlined in the contract agreement between EMC and the City of Jeffersonville, benchmark loading's in the first year of the contract are used to determine if a 10% increase or decrease in loadings to the facility has occurred during the previous contract year (Page 7 of the contract). This mechanism is used to determine if the compensation paid to EMC should be adjusted upward or downward to reflect the change. The following percent changes occurred this past year: ~ Flow (mgd) Pounds of Total Suspend Solids (TSS) Pounds of Biochemical Oxygen Demand (BOD) increased 60% increased 99% increased 216% ~ ... The increase in flows and loadings created a significant impact on EMC's cost to operate the treatment facility. The expense items most impacted by the increased loadings were electrical, chemical usage (polymer), and sludge disposal. .-- , ..-. I . i [ r , t , ..

At the end of the first twelve months of the Agreement, EMC will submit the following data to the City for the purposes of establishing benchmark flows and loadings for the Facilities. A verage Annual Daily Flow: A verage Daily Influent BOD: A verage Daily Influent TSS: 3.635 MGD 3649 lbs. 7753 lbs. Upon the City's approval of this data, the above blanks will be filled in with the appropriate figures and will serve as the benchmark data for this Agreement. If during any twelve month period the average flow and/or loadings increase or decrease by 10% or more, the compensation to EMC may be adjusted upward or downward to reflect the change. Theparties will negotiate this adjustment to reflect actual cost data submitted by EMC, to the extent that such data are available and can be traced to the flow and loadings changes. ' Compensation. During the first twelve months, the City shall pay EMC, as compensation for the services to be performed as described in this Agreement, the sum of $97,624.08 pe~month ($1,171,489.00 annually) with adjustments as specified hereinafter. Monthly payments are due the 10th of each month for which services will be rendered, upon presentation of invoices by EMC. Late payments shall accrue interest at the then current prime rate plus one percent per annum on the unpaid balance. The amount of compensation due EMC as outlined above may be reduced by a maximum of 15% of the annual overhead and profit line item in the "cost analysis and proposal schedule" of the Cost Proposal submitted to the City by EMC based on unsatisfactory levels consistent with thee "Quarterly Performance Scorecard" executed by the City and EMC, which is incorporated by reference' herein. It is understood that each quarterly review would place at risk one-quarter of the maximum annual amount defined above. Of this annual compensation amount, $1,071,489 shall be adjusted on May 1, 1995 and on every subsequent May 1 date of the contract term. The adjustment will be based upon the percentage change in the CPI-North Central Class D for the entire period preceding each adjustment date. Annual compensation adjustments will be cumulative. Notwithstanding the actual percentage change in CPI, it is agreed that the minimum amount of the adjustment based on the CPI change shall be 3% annually and the maximum amount shall be 6%.

The expenditures include the wastewater treatment facility and all 29 lift stations. The actual expenditures for this period was $208,148.43. As discussed on page 8, (Electrical Cap) of the contract between EMC and the City of Jeffersonville, the cap was exceeded. Th~ cap for the above mentioned period of time was $186,414.60. The difference between the actual expenditures and the cap was $21,733.83. Due to the expenditures exceeding the electrical cap, EMC is to reimburse the City in the amount of$21,733.83. The reason for the increased electrical cost can be attributed to the extremely wet weather, and increased Total Suspended Solids and Biochemical Oxygen Demand Loadings to the facility. The wet weather re..quired a significant increase in pumping at the various lift stations and increase in equipment use at the wastewater facility in order to provide proper treatment of the excessive amounts of wastewater. As always, EMC appreciates the opportunity to serve the City of Jeffersonville. If you may need additional information or would like to discuss this report or any other aspect of the operation, do not hesitate to contact me.
