reached 85% of the initial design capacity, the commission would institute a program to expand and/or upgrade the treatment system beyond the initial design capacity. This trigger point is now being reached for several of the unit process capacities. In the mid-1990s, the regional wastewater treatment facilities were modified to improve their performance, and the commission recognized that the facilities were experiencing capacity limitations relative to original design specifications. As a result, additional expansions would be needed to actualize the projected 2004 design life. In 1996, the commission responded with a directive to produce a master plan to evaluate short-term and long-range improvements necessary to improve facility operations and meet increasing capacity and evolving performance demands. The MWMC Master Plan was completed in 1997. Although it is not as comprehensive as the 2004 Facilities Plan, it did provide analysis of historic flows, pollutant loads, and reporting data to identify capital improvements needed to resolve shortfalls in the capacity for biosolids processing and peak flow management. Later in 1997, the commission adopted the Biosolids Management Plan, which was derived from a Citizen Advisory Committee (CAC) and engineering evaluation processes. This plan reflects the commission' s adoption of strategy to resolve shortfalls in biosolids processing capacity and is based upon an evaluation of available technologies, cost effectiveness, reliability, and public acceptance. The biosolids dewatering facility (completed in 2001), the ongoing maintenance of drying beds, the composting operation, the cooperative land application on private farms, and the development of the Biocycle Farm are the beneficial results of the commission's adopted biosolids management strategy. To address the peak flow capacity issues, the commission, the City of Eugene, and the City of Springfield adopted the WWFMP in 2001. The objectives of this plan were to eliminate overflows and basement flooding and provide the most cost-effective means to mitigate flows in excess of system capacity. The plan developed a sophisticated hydraulic model that was calibrated and refined with actual system performance over several years of the study. The Wet Weather CAC reviewed a wide mix of solutions and recommended the policies and capital improvements included in the WWFMP, and the plan remains the guiding policy document in setting the cities' annual CIP for sanitary sewer rehabilitation and replacement, as well as the commission's capital improvements and operations for addressing peak flows. Timing Planning projections indicate that important capacity limitations and needs for upgraded treatment capabilities will be realized in the relative short-term future. In addition, optimization of the various capital projects to meet multiple objectives and maximize the capabilities of existing infrastructure requires an integrated and synchronized process for design and construction. This process needs appropriate lead-time in order to ensure that the necessary projects can be designed, built, and brought on-line in time to meet regulatory deadlines and increased demands on the wastewater system. The significant financial needs presented by the magnitude of the Facilities Plan Project List also require careful planning for adequate cash-flow and implementation of revenue generation processes. While the commission is assigned the responsibility of planning for plan upgrade/expansion, and for constructing, operating, and maintaining them, the MWMC 2004 Facilities Plan and 20-Year Project List are being forward to the governing bodies for consideration, as it will in result expanded capacity and provide for community growth through 2025. Therefore, the commission is formally requesting that the governing bodies acknowledge their concurrence with the 2004 Facilities Plan. The City of Eugene has a scheduled work session on May 19, a public hearing on June 14, and council action on June 28. L:\CMO\2004 Council Agendas\M040519\S040519A. doc
