INFORMATION SHEET <br /> ORDER NO. <br /> OWENS-BROCKWAY GLASS FURNACE FACILITY, OWENS-ILLINOIS <br /> SAN JOAQUIN COUNTY <br /> Owens-Brockway, a subsidiary of Owens-Illinois, operates a glass furnace facility at 14700 W. Shulte <br /> Road, in Tracy, San Joaquin County. The facility stockpiles raw material, manufactures glass <br /> products, and warehouses products prior to shipment. In January 2000, Owens-Brockway submitted a <br /> Report of Waste Discharge. The facility generates approximately 18,000 gallons per day from cullet <br /> water, overflow , furnace drain water , cooling tower overflow, reverse osmosis reject water and <br /> cleaning water(collectively process water). The process wastewater is discharged to three evaporation <br /> and percolation ponds. <br /> Approximately 14,000 gallons per day of domestic wastewater is discharged to a primary septic tank <br /> and leachfield. A second small septic tank and leachfield serves a leased portion of the facility. All <br /> stormwater is discharged to several stormwater ponds where it percolates to the subsurface. <br /> Depth to the first water bearing zone is approximately 75 feet. A 100-foot thick aquitard exists below <br /> the first water bearing zone. The plant water supply is provided by a water well screened in deep <br /> aquifer zones below the aquitard. Groundwater in the deep aquifer zone contains elevated <br /> concentrations of total dissolved solids. Four groundwater monitoring wells exist at the facility; one of <br /> the wells has been dry from the time of installation. Two sample events have been performed with the <br /> groundwater monitoring wells. Elevated concentrations of TDS, specific conductance, and other <br /> compounds consistent with the process wastewater disposal were reported in the groundwater <br /> monitoring well located adjacent to the wastewater evaporation and percolation ponds. <br /> Under these Waste Discharge Requirements, effluent, pond, and groundwater monitoring will be <br /> required. Additional groundwater monitoring wells will be installed to better characterize and monitor <br /> shallow groundwater. A determination of whether groundwater has been impacted by pond discharges <br /> shall be made. Monitoring data will be used to determine whether wastewater treatment and/or pond <br /> mitigation efforts are necessary. <br /> tro <br /> C:\Projal_Films Si¢slOwmslllwois\info.dx <br />
