meet the region’s needs for increased sewerage service and ensure compliance with the facility’s NPDES discharge permit. The Residuals Treatment Project is located at the Biosolids Management Facility (BMF) on Awbrey Lane in Lane County. The BMF’s function is to store, further stabilize, and dry digested biosolids received from the WPCF. The Beneficial Reuse Project is located at the Biocycle Farm along Highway 99 in Lane County. The Biocycle Farm’s function is to apply biosolids from the adjacent BMF to poplar trees, which absorb the water and nutrients contained in the biosolids. Conveyance: Conveyance capacity and inflow and infiltration (I/I) ratios are important criteria by which to assess the performance of a wastewater collection system. Conveyance capacity is a function of adequate pipe sizing and measures a system’s ability to move effluent efficiently. Inflow and infiltration ratios express the amount of stormwater entering a sewer system through defective pipes and pipe joints, or through the cross connection of stormwater lines, combined sewers, catch basins, or manhole covers. Such extraneous stormwater entering the wastewater system unnecessarily burdens both conveyance and treatment facilities. Capacity: The capacity of the wastewater system is expressed in four measures: average flow, peak flow, biochemical oxygen demand (BOD) and total suspended solids (TSS). The system’s current capacities and projected 2025 needed capacities are: Capacity Measure Current 2025 Average flow 49 mgd 59.3 mgd Peak flow 175 mgd 277 mgd BOD 66,000 lbs/day 74,000 lbs/day TSS 71,600 lbs/day 87,600 lbs/day Projects 300 through 305, described in Tables 4a and 4b, are designed to work together to increase the overall system capacities to meet the projected 2025 need. 5. Modify Chapter IV. Of the Public Facilities and Services Plan, by modifying the discussion of wastewater, in the subdivision entitled “Long-Term Service Availability Within Urbanizable Areas” (presently on page 97) to read as follows: 1. There are no areas within the metropolitan UGB that will be difficult to serve with wastewater facilities over the long-term (six to 20 years) assuming that public infrastructure specifications and requirements of the developing area can be addressed. Appropriate engineering design practices must be used during the development and expansion into sensitive areas that are approved for development (ex. – hillside construction, etc.). Expansion of the existing collection system will be necessary to meet demands of growth over this time period. 2. Based on 2003 analysis, the Eugene-Springfield metropolitan area treatment facilities will require facility improvements to address both dry and wet weather regulatory requirements relating to pollutant loads and wastewater flows. Regional and local wastewater improvements to the collection and treatment systems are being planned for and will be implemented to allow for growth within the UGB and for regulatory compliance.
