Metropolitan Wastewater Management Commission Eugene Budget Detail <br />services contracting. Also included within the Maintenance section's charge are the pump <br />stations and sewers in the regional and local collection system, and the facilities and equipment <br />at the Biosolids Management and Seasonal Industrial Waste Facilities. <br />BIOSOLIDS MANAGEMENT <br />The biological solids (Biosolids) produced as a result of the activated sludge treatment of <br />wastewater is managed by the Residuals Management section of the Wastewater Division. <br />This section operates the Biosolids Management Facility (BMF) located at Awbrey Lane in <br />Eugene. Approximately 4,438 dry tons of Biosolids are produced annually by the WPCF. <br />These Biosolids aze treated using anaerobic digestion, stored in facultative lagoons (which <br />provide some additional treatment benefits), and then air-dried to reduce the water content and <br />facilitate transport. The dried material is ultimately recycled to agricultural land as a beneficial <br />fertilizer and soil conditioner. <br />INDUSTRIAL SOURCE CONTROL (Pretreatment) <br />The pretreatment program is a regional activity implemented jointly by the cities of Eugene <br />and Springfield. The Industrial Source Control (ISC) section of the Wastewater Division is <br />charged with administering the pretreatment program for the regulation and oversight of <br />wastewaters discharged to the sanitary collection system by fixed-site industries in Eugenie and <br />by mobile waste haulers in the Eugene and Springfield azeas. ISC is responsible for ensuring <br />that these wastes do not damage the collection system, interfere with wastewater treatment <br />processes, result in the pass-through of harmful pollutants to treated effluent or Biosolids, or <br />threaten worker health or safety. . <br />This responsibility is fulfilled through the use of a permit system for industrial dischargers. <br />This permit system, common to both Eugene and Springfield, implements necessary limitations <br />on waste characteristics and establishes inspection, monitoring, and reporting requirements for <br />documenting waste quality and~quantity controls. The ISC staff is also responsible for locating <br />new industrial dischazges in Eugene and evaluating the impact of new non-residential <br />discharges on the WPCF. As of January 2002, there were 21 significant industrial users under <br />permit in Eugene. <br />The ISC unit also has responsibilities related to environmental spill response activities and <br />ambient and stormwater quality monitoring. <br />REGIONAL ENVIRONMENTAL ANALYTICAL SERVICES <br />The Environmental Analytical Services Laboratory provides necessary analytical services in <br />support of wastewater treatment, residuals management, industrial source control, stormwater <br />monitoring, and special project activities of the Wastewater Division. The Laboratory's <br />services include sample handling and analyses of influent sewage, treated wastewater, <br />Biosolids, industrial wastes, cannery wastewater, stormwater, and groundwater. Information <br />from the Laboratory is used to make treatment process control decisions, document compliance <br />with regulatory requirements, demonstrate environmental protection, and ensure worker health. <br />and safety. <br />Page 41 FY 02-03 Budget <br />
