Metropolitan Wastewater Management Commission Eugene Budget Detail a facility maintenance program to maintain the buildings, treatment structures, and grounds; and a stores unit that purchases and stocks parts and supplies and assists with professional services contracting. Also included within the Maintenance section's charge are the pump stations and sewers in the regional and local collection system, and the facilities and equipment at the Biosolids Management and Seasonal Industrial Waste Facilities. BIOSOLIDS MANAGEMENT The biological solids (biosolids) produced as a result of the activated sludge treatment of wastewater is managed by the Residuals Management section of the Wastewater Division. This section operates the Biosolids Management Facility (BMF) and Biocycle Farm located at Awbrey Lane in Eugene. Approximately 4,750 dry tons ofbiosolids are produced annually by the WPCF. These biosolids are treated using anaerobic digestion, stored in facultative lagoons (which provide some additional treatment benefits), and then air-dried to reduce the water content and facilitate transport. The dried material is ultimately recycled to agricultural land as a beneficial fertilizer and soil conditioner. In 2004 the first phase of the Biocycle Farm will begin operations, beneficially reusing biosolids through irrigation on poplar trees. This section also manages the Seasonal Industrial Waste (SIW) facility. INDUSTRIAL SOURCE CONTROL (Pretreatment) and ANALYTICAL SERVICES, SAMPLING TEAM The pretreatment program is a regional activity implemented jointly by the cities of Eugene and Springfield. The Industrial Source Control group of the Wastewater Division is charged with administering the pretreatment program for the regulation and oversight ofwastewaters discharged to the sanitary collection system by fixed-site industries in Eugene and by mobile waste haulers in the Eugene and Springfield areas. This group is also responsible for ensuring that these wastes do not damage the collection system, interfere with wastewater treatment processes, result in the pass-through of harmful pollutants to treated effluent or biosolids, or threaten worker health or safety. This responsibility is fulfilled through the use of a permit system for industrial dischargers. This permit system, common to both Eugene and Springfield, implements necessary limitations on waste characteristics and establishes inspection, monitoring, and reporting requirements for documenting waste quality and quantity controls. The staff is also responsible for locating new industrial discharges in Eugene and evaluating the impact of new non-residential discharges on the WPCF. As of January 2005, there were 22 significant industrial users under permit in Eugene. The section also has responsibilities related to environmental spill response activities. The Analytical Services group provides necessary analytical work in support of wastewater treatment, residuals management, industrial source control, stormwater monitoring, and special project activities of the Wastewater Division. The laboratory's services include sample handling and analyses of influent sewage, treated wastewater, biosolids, industrial wastes, stormwater, and groundwater. Information from the laboratory is used to make treatment process control decisions, document compliance with regulatory requirements, demonstrate environmental protection, and ensure worker health and safety.
