. ~.5 ~ .. <br />located at the drill sites. All of the bulk cement transfer is done using pneumatic systems. which <br />• should minimize the amount of dust and reduce the possibility of spills. Chesnik Construction <br />personnel will provide dozer assistance as needed for the lazge trucks that will deliver the bulk <br />cement [o the drill sites. We wilt plan to resupply the bins at the drill sites during night-time <br />hour. <br />Two large water storage tanks (?0,000 gallons each) will be Located at the drill sites. One tank <br />will be mobilized to the drill site by Sunday, Iv[azch ~'°, so that we can begin filling the tank with <br />water. The second tank will be mobilized to the drill site following the completion of the batch <br />testing at the mine site. Lang Drilling will be filling the water storage tanks with their water <br />trucks using water from [he ivlinnesota Reservoir. We expect tha[ approximately 3.000 gallons <br />of water will be required to complete the seals. It is expected that water will be hauled from the <br />reservoir to the drill sites on a continual basis during the project. <br />Halliburton will begin mobilizing their other equipment, including a bulk cement pump truck. <br />ni[rogen/foam cemen[ pump truck. L300 gallon diesel tank, chemical batch truck. control van, <br />and other miscellaneous control equipment. to the drill sites on ~fondav, t~(arch 6'" or Tuesday, <br />March T°, depending on the results of the batch testing. Mobilization and set-up at [he drill sites <br />will likely take two to three days. Each seal will require one to tvvo days to cons[ruct. <br />All materials and products for the foam cement will be contained at the corrals and on the drill <br />sites. Drill pads are bermed to ensure that any spills and stormwater will be contained on the <br />• pad. btud pits currently constructed on the drill sites will be used to capture equipment wash <br />down. Halliburton is expected to take care of any spill immediately. MCC expects that the mud <br />pits may need to be enlazged or cleaned-out prior to beginning this project. All cleanings will be <br />contained on the drill site. <br />Reclamation of the roads and drill pads will be addressed in a letter to be provided under sepazate <br />cover. However, Chesnik construction will be available throughout the Halliburton project to <br />grade roads as needed. and will regrade roads following the completion of the project. <br />The second step involved with extinguishing the combustion will involve pumping water from <br />either [CC's I? million gallon warer tanl: or Minnesota Reservoir through a pipeline. to one of <br />the drill holes and down into the mine to t]ood the combustion area. The details of this project <br />have not been worked out yet. and ~[CC will con[inue to inform you as this plan is finalized. <br />MCC appreciates the USFS's cooperation during this emergency. As you know from our <br />telephone conversations. locating the combustion area has bean a dynamic process and we <br />discover ne~v information about our situation each day. The above description represents the <br />best information we have at this time resazdine the construction of the seals. As the details are <br />finalized. and as we determine which holes will be utilized, and how many seals will be <br />constructed. [will notify you. <br /> <br />
