2.0 Regi nal Metropolitan Wastewater Management Commission Wastewater <br /> Syste Development Charge (Regional Wastewater Charge) <br /> 2.1 WMC Wastewater SDC Formula <br /> In add tion to the local wastewater SDC collected, a Metropolitan Wastewater <br /> Mana ement Commission (MWMC) Systems Development Charge (also known as the <br /> Regio al Wastewater SDC) will be collected on all new connections to the system. This <br /> charg is a combined reimbursement and improvement SDC. The Charge is meant to <br /> recou the region's investment in reserve sewage treatment capacity and recover an <br /> equity le share of the capital necessary to increase capacity for new development. This <br /> charg is imposed on all new connections by all new or existing development in the <br /> Euge e-Springfield area, and for expansion or changes in use of existing development <br /> that in rease impact on the MWMC facilities. When recommended by MWMC, the City <br /> will ad pt amendments to this methodology pursuant to EC 2.019 and 2.020. <br /> <br /> I'~, The r imbursement fee is based on the current value of the regional wastewater facilities <br /> in pla a 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 /> region I wastewater facilities reveals that there are several individual measures of <br /> capac y which impact cost and together determine the overall capacity of the regional <br /> waste ater system. These measures of capacity are average flow, peak flow, <br /> bioch mica) oxygen demand (BOD), and suspended solids (SS). The present capacity of <br /> thew stewater facilities are shown in Table 5. Based upon the regional system analysis, <br /> the v lue of the regional system is allocated to each of these types of capacity, reflected <br /> in the ercentages shown in Table 5. Costs per unit of each capacity measurement can <br /> be det rmined by dividing each measurements allocation of local equity by its capacity. <br /> The i provement fee is based on the estimated future cost of capacity-increasing <br /> projec s included in the MWMC five year capital improvement program at the time the fee <br /> is calc lated, the allocation of that future cost to the capacity measurements, and the <br /> amou t of each type of capacity being increased for each element. MWMC intends to <br /> maint in a twenty year schedule of capital projects and for individual capacity-increasing <br /> capital projects to be scheduled to begin when one or more of the individual <br /> meas rements of capacity are estimated to reach 85% of their design. Projects will move <br /> into th MWMC CIP as their scheduled construction year enters the CIP's five year <br /> windo <br /> 2.2 alculating the MWMC wastewater SDC <br /> The M MC wastewater SDC shall be determined by using the reference data contained <br /> in Atta hment 4 of this Appendix C which describes flow estimation units (FEU) and <br /> associ ted flow and strength impacts of various types of development together with the <br /> unit c t of flow, BOD, and SS. If information for a particular development is not found in <br /> Attach ent 4, it shall be formulated using average data of like or similar development as <br /> deter fined by the City Engineer. For any development, the MWMC wastewater SDC is <br /> deter fined by the following formula: <br /> ~ ultiply the estimated gallons per day of flow per FEU, estimated pounds per day <br /> OD per FEU, and estimated pounds per day SS per FEU by their respective unit <br /> st, <br /> City of Eug ne SDC Methodology Wastewater, Page C- 7 <br /> <br />
