Box 30 <br /> �- Tracy, CA 95376-0030 <br /> SU TECi': OWENS-BROCKWAY UASS CONTAINERS - GROUND WATER <br /> MONITORING WORKPLAN <br /> Dear Mr. Hamrick <br /> Enclosed is the final draft of the ground water monitoring workplan for the Owens-Brockway <br /> facility. The workplan was prepared in response to the February 15, 1944 letter from the <br /> Regional Water Quality Control Board, Central Valley Region (Appendix A). Described in <br /> the workplan are regional ground water information and recommendations detailing how <br /> additional information about ground water conditions in the area of the Owens-Brockway <br /> facility can be obtained. The workplan also includes a water halance calculation of the <br /> Owens-Brockway facility wastewater disposal ponds. <br /> BACKGROUND <br /> The Owens-Brockway Glass Containers facility is located at 14700 West Schulte Road in the <br /> Town of Tracy. The process wastewater disposal system is located on the facility grounds <br /> and consists of three evaporation ponds. Five additional storm water retention/detention <br /> ponds are also located on the facility grounds which receive storm water runoff from the site. <br /> Plant sanitary discharges are treated by the plant's septic system. A location map for the <br /> Owens-Brockway Glass Containers Facility is presented in Figure 1. <br /> The three wastewater evaporation ponds receive backwash water from a reverse osmosis (RO) <br /> system and a small amount of excess process water. The three wastewater evaporation ponds <br /> have a combined surface area of approximately 0.57 acres with an average depth of <br /> 71-811. <br /> The process water consists of water used to steam clean equipment, wash the floors, and from <br /> the arts and ramp pressure testers. The process water is collected in the water circulation <br /> system in the facility's basement. Skimmers are used in the circulating system to remove oil <br /> NOLTE and ASSOCIATES,Inc. <br /> Engineers / Planners / 5urveynr5 <br /> 1750 Creekside oaks or.,Suite 2110,SaCramentc,CA 95833 Tel:(416)641-1500 FAX:(91 61 641-9222 <br />
