2.0 Regional Metropolitan Wastewater Management Commission Wastewater System Development Charge (Regional Wastewater Charge) 2.1 MWMC Wastewater SDC Formula In addition to the local wastewater SDC collected, a Metropolitan Wastewater Management Commission (MWMC) Systems Development Charge (also known as the Regional Wastewater SDC) will be collected on all new connections to the system. This charge is a combined reimbursement and improvement SOC. The Charge is meant to recoup the region's investment in reserve sewage treatment capacity and recover an equitable share of the capital necessary to increase capacity for new development. This charge is imposed on all new connections by all new or existing development in the Eugene-Springfield area, and for expansion or changes in use of existing development that increase impact on the MWMC facilities. When recommended by MWMC, the City will adopt amendments to this methodology pursuant to EC 2.019 and 2.020. The reimbursement fee is based on the current value of the regional wastewater facilities in place on the date the rate is established. Outstanding debt and any state and federal grants are subtracted from this amount to determine the local equity. An analysis of the regional wastewater facilities reveals that there are several individual measures of capacity which impact cost and together determine the overall capacity of the regional wastewater system. These measures of capacity are average flow, peak flow, biochemical oxygen demand (BOD), and suspended solids (SS). The present capacity of the wastewater facilities are shown in Table 8. Based upon the regional system analysis, the value of the regional system is allocated to each of these types of capacity, reflected in the percentages shown in Table 8. Costs per unit of each capacity measurement can be determined by dividing each measurements allocation of local equity by its capacity. The improvement fee is based on the estimated future cost of capacity-increasing projects included in the MWMC five year capital improvement program at the time the fee is calculated, the allocation of that future cost to the capacity measurements, and the amount of each type of capacity being increased for each element. MWMC intends to maintain a twenty year schedule of capital projects and for individual capacity-increasing capital projects to be scheduled to begin when one or more of the individual measurements of capacity are estimated to reach 850/0 of their design. Projects will move into the MWMC CIP as their scheduled construction year enters the CIP's five year window. 2.2 Calculating the MWMC wastewater SDC The MWMC wastewater SDC shall be determined by using the reference data contained in Table 10 which describes flow estimation units (FEU) and associated flow and strength impacts of various types of development together with the unit cost of flow, BOD, and SS. If information for a particular development is not found in Table 10, it shall be formulated using average data of like or similar development as determined by the City Engineer. For any development, the MWMC wastewater SDC is determined by the following formula: }> Multiply the estimated gallons per day of flow per FEU, estimated pounds per day BOD per FEU, and estimated pounds per day SS per FEU by their respective unit cost; City of Eugene SDC Methodology Wastewater, Page C-7
