ITEMS TO DISCUSS <br />1. Design of perimeter monitoring wells <br />a. Probe pipe to bottom of rock section <br />b. Weights at bottom: specify total weight <br />c. Adjustments for soils types — avoid blocking high permeability soil lenses <br />2. Working hours: <br />a. Drilling: 7:00 am to 5:00 pm <br />b. Installation: 9:00 to 4:00 <br />a. Lunch break? <br />b. Provisions for overtime? <br />c. Other County staff in lieu of EHD staff? <br />3. Possible field adjustments <br />a. Depth to bottom of rock sections (depth of probes) by Solid Waste based on soils. <br />Avoid blocking high permeability layers with bentonite seals. <br />b. Others as needed to address field conditions, as long as key construction features <br />are maintained (depth of well, placement of probes) <br />c. (more?) <br />4. Items requiring direct EHD inspection <br />a. Depth to <br />i. Bottom of hole <br />ii. Top or bottom of rock sections (probe is at bottom of rock section) <br />b. Bentonite seals and top sand grout <br />c. (more?) <br />5. All other items can be installed without direct EHD inspection: <br />a. Drilling (no installation in hole w/o inspection) <br />b. Bollards and cattle fences <br />c. Removal of soil <br />d. Labeling probes <br />e. Painting <br />f. (more?) <br />6. Items to be available to EHD inspector by CQA monitor: field drilling log, focusing on soil <br />horizons (may vary in characterization from final log. <br />K <br />
