u S%J Kellogg Garden Products ECO:LOGIC Engineering Groundwater Monitoring Well Installation Work Plan KELG04-001 11/10/2004 feet above land surface to a depth of 4.0 feet. A 3.5-foot diameter, 4-inch thick concrete pad will be poured surrounding each well. Well Cap—2-inch diameter expandable, lockable pressure plug. Surface Seal—Neat cement or cement grout will be placed from the land surface to a minimum depth of 20 feet and to the top of the bentonite seal. A minimum 2-feet of granular bentonite seal will be placed from the top of the filter pack to the bottom of the neat cement surface seal. Note that, where required,the above ground completion of the monitoring wells will have a minimum of three 6-inch diameter steel bollards filled with concrete. The above surface completion program is preferred to one where the top of the monitoring well is encased in a subsurface box set at grade. The latter runs the risk of having the well polluted by surface water that enters the box and covers the top of the monitoring well. Figures 4 and 5 depict a typical monitoring well completion anticipated for this site. EQUIPMENT DECONTAMINATION PROCEDURES Decontamination will comprise a hot water pressure wash of the drilling equipment and well purging and flushing equipment with a non-phosphate detergent, followed by a clean water rinse. As a precaution against cross-contamination between boreholes, the drilling and flushing equipment will be decontaminated prior to the start of drilling or flushing of the first monitoring well and between each successive monitoring well. HEALTH AND SAFETY PLAN Personal Protective Equipment The Kellogg facility currently directs contact water(water in contact with composting materials)to the Contact Water Pond for reuse or evaporation. Risks of exposure to hazardous chemical or biological agents originating from the effluent is minimal. The practice of good personal hygiene by the crew is warranted and will further reduce the exposure risk. Affected areas of the body shall be washed with clean soapy water followed by a clean water rinse. Level D personal protection equipment comprising a standard work uniform(coveralls,hard hat, gloves, steel- toed boots,safety glasses,hearing protection,etc.)shall be in practice during all work at the site. Emergency Procedures The telephone numbers of the appropriate entities to be contacted in case of emergency are as follows: San Joaquin County Sheriff:Emergency 911,Non-emergency(209)468-4400;209-468-4167(fax) Lockeford Fire District: Emergency 911,Non-emergency 209-727-0564 The nearest trauma center or emergency medical facility is: Lodi Memorial Hospital-Emergency Room 1235 W Vine St,Lodi,CA 95240 209-339-7600 The driving route to Lodi Memorial Hospital is contained in Appendix B. DRILLING DETAILS Prior to drilling, permits will be obtained for well construction from the San Joaquin County Department of Environmental Management,Environmental Health Division: 5
