Attachment #7 of Exhibit A <br />Administrative Order No. 58-97-07-F <br />Page 2 of 6 <br />2.2 .Calculating the MWMC .SDC <br />:.The MWMC SDC shall be determined by using-the reference data contained in Attachment <br />4 of this Appendix D which describes flow estimation units (FEU)-and associated,flow and <br />strength impacts of various types of development together with the unit cost of flow, BOD, ~- <br />and SS. If information for a particular development is not found in Attachment 4, it shall be <br />formulated using average data of like or similar development as determined by the City <br />Engineer. For any development, the MWMC SDC is determined by the following formula: <br />I 1. .Multiply the estimated gallons per day of flow per FEU, estimated. pounds per day BOD <br />per FEU., and estimated pounds per day SS per. FEU by their respective unit cost; <br />2. Sum these amounts, to .derive a total .cost per FEU, for a specific type of development; <br />~ 3. `Multiply the total cost per FEU for a development type by the number of FEUs for a <br />development application. <br />For more detailed and specific numerical data on FEU calculations, see Table 5. For formula <br />llustrations, see Figure 5 in this Appendix. <br />2.2.1 Process Wastewater <br />The MWMC SDC for development that discharges process wastewater to the <br />wastewater system'wiH be charged on the basis of the strength of that discharge. The <br />rates per. FEU for land uses .listed in Attachment 4 of this. Appendix include process <br />wastewater charges. For uses not otherwise listed in Attachment 4 that include process <br />wastewa#er, the MWMC SDC will. be.calculated by combining the charge for unit of <br />development .for general. industrial uses, and adding the charge. for the process <br />wastewater FEU that matches the strength of the proposed discharge. The strength <br />classes shown in Attachment 4 are the same strength classes used by MWMC in the <br />user fee system.. , <br />2.2.2 Regional Wastewater SDCs For AI! New Development with Annual Average <br />Daily Flow Equal to or Greater than 100,000 Gallons, and for Existing Development: <br />lncreasing Flow by or Greater than 100,000 Gallons per Day <br />Before calculating the SDC for any development with an anticipated discharge of <br />100,000 gallons or more of sewage per day, the Executive Officer of the MWMC (EO) <br />shall examine the developments impact on the twenty year schedule of capital projects: <br />If one or more capacity-increasing. projects will moveintothe 5-year CIP as a result of <br />the development,. the EO will establish new unit costs (based on the. total costs of the <br />amended 5-year CIP) upon which SDCS for all development will be calculated. If the. <br />:.MWMC. SDC rate is modified, the modified. fee will be applied to the development. that <br />caused the need for the modification and to all future development. <br />:July 7, 1997 ~ City of Eugene SDC Methodology Page D-7 <br />
