Monitoring Well B8 Plans and Specifications Kiuitas County Solid Waste site while drilling operations take place. At the completion of the field activities, the CONTRACTOR shall restore the drilling site to its pre -drilling condition as specified in Section 2.1.3, In the event that any damages to the site property occur because of the CONTRACTOR'S activities, the CONTRACTOR shall, at their own expense, repair the damages or reclaim the land to the extent deemed suitable by the GEOLOGIST. 2.2 , 2 Decontamination Procedures All large drilling equipment (rods, bits, drill rig, etc.) will be steam cleaned with a high-pressure washer prior to drilling the well and after completion of the final well. The area designated for steam cleaning activities will be located at least 50 feet away from the well site, or as designated by the GEOLOGIST and OWNER. Rinse water from steam cleaning can be disposed of on -site in the easternmost lined leachate evaporation pond (See Sheet A-2), Coordinate with the site contact prior to disposal for access to the pond. 2.2.3 Borehole Logging Borehole logging shall be conducted by the GEOLOGIST for the purpose of this project and must also be done by the CONTRACTOR for fulfillment of state requirements. The CONTRACTOR shall endeavor to provide information on drilling conditions that will assist the GEOLOGIST in making determinations of subsurface material character including but not limited to soil and groundwater conditions, voids, sloughing and soil collapse, and penetration rates. 2.2.4 Alignment Alignment requirements during drilling are that any casing, liner, or drill tools can be run freely through the boring. At a minimum, the alignment shall conform to Chapter 173-160-191 WAC. 2.2.5 Abandonment Any well that does not meet the alignment or other requirements, or which is contaminated by the CONTRACTOR, or any well on which the CONTRACTOR stops work will be considered abandoned. Once a well installed by the CONTRACTOR has been designated as abandoned, the CONTRACTOR, at their own expense down to the last drilling depth, shall initiate installation of a new well in the immediate vicinity at a location designated by the GEOLOGIST. The CONTRACTOR may, at their own expense, remove any ungrouted casing. At a minimum, all abandoned wens shall be completed in accordance with decommissioning standards of Chapter 173-160-460 WAC. 2.2.6 Determining Appropriate Drilling Depth Drilling completion depth at the well location will be confirmed by the CONTRACTOR with the GEOLOGIST_ If the CONTRACTOR anticipates the final drilling depth will not be reached due to site conditions, the CONTRACTOR shall contact the OWNER and GEOLOGIST immediately to determine appropriate actions. The anticipated drilling depth for the well is 200 feet below ground surface with the top of the Vantage Interbed estimated to be approximately 190 feet below ground surface. The CONTRACTOR shall bring enough drilling materials to advance the borehole and complete a monitoring well to a minimum of 250 feet below ground to avoid any downtime for mobilization of equipment/materials. 10 February 2025 1553-1763-010
