2.0 Regional Metropolitan Wastewater Management Commission Wastewater <br />System Development Charge (Regional Wastewater Charge). <br />2.1 MWMC Wastewater SDC Formula <br />In addition to the local wastewater SDC collected, a Metropolitan Wastewater Management <br />mmission (MWMC) Systems Development Charge (also known as the Regional <br />Wastewater SDC) will be collected on all new connections to the system. This charge is a <br />combined reimbursement and improvement SDC. The Charge is meant to recoup the <br />region's investment in reserve sewage treatment capacity and recover an equitable share of <br />the capital necessary to increase capacity for new development. This charge is imposed on <br />all new connections by all new or existing development in the Eugene-Springfield area, and <br />for expansion or changes in use of existing development that increase impact on the MWMC <br />facilities. When recommended by MWMC, the City will adopt amendments to this <br />methodology pursuant to EC 2.019 and 2.020. <br />The reimbursement fee is based on the current value of the regional wastewater facilities <br />in place on the date the rate is established. Outstanding debt and any state and federal <br />grants are subtracted from this amount to determine the local equity. An analysis of the <br />regional wastewater facilities reveals that there are several individual measures of capacity <br />which impact cost and together determine the overall capacity of the regional wastewater <br />system. These measures of capacity are average flow, peak flow, biochemical oxygen <br />demand (BOD), and suspended solids (SS). The present capacity of the wastewater facilities <br />are shown in Table 5. Based upon the regional system analysis, the value of the regional <br />system is allocated to each of these types of capacity, reflected in the percentages shown <br />in Table 5. Costs per unit of each capacity measurement can be determined by dividing each <br />measurements allocation of local equity by its capacity. <br />The improvement fee is based on the estimated future cost of capacity-increasing projects <br />included in the MWMC five year capital improvement program at the time the fee is <br />calculated, the allocation of that future cost to the capacity measurements, and the amount <br />of each type of capacity being increased for each element. MWMC intends to maintain a <br />twenty year schedule of capital projects and for. individual capacity-increasing capital projects <br />to be scheduled to begin when one or more of the individual measurements of capacity are <br />estimated to reach 85% of their design. Projects will move into the MWMC CIP as their <br />~s~cheduled construction year enters the CIP's five year window. <br />2.2 Calculating the MWMC wastewater SDC <br />The MWMC wastewater SDC shall be determined by using the reference data contained in <br />Attachment 4 of this Appendix C which describes flow estimation units (FEU) and associated <br />flow and strength impacts of various types of development together with the unit cost of flow, <br />BOD, and SS. If information for a particular development is not found in Attachment 4, it shall <br />be formulated using average data of like or similar development. as determined by the City <br />Engineer. For any development, the MWMC wastewater SDC is determined by the following <br />formula: <br />1. Multiply the estimated gallons per day of flow per FEU, estimated pounds per day BOD per <br />tFEU, 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 />City of Eugene SDC Methodology Wastewater, Page C-7 <br />
