We would also retrieve some limestone core from the overlying limestone layer we are <br /> currently mining. <br /> Equipment and Coring Technique: <br /> The equipment we plan to use for drilling would either be a diesel-hydraulic Ingetrol 75F trailer mounted <br /> drill or a similar drill mounted on a rubber-tired flat-bed truck. Other equipment on-site at the time of <br /> the drilling would include a 4x4 truck, a small compressor, one or two 500-1000 gallon water tanks, and <br /> a 100 gallon fuel tank on the drill trailer. Core drilling would be performed using fresh water delivered to <br /> the site and placed within a pre-existing 2500-gallon storage tank. <br /> Drilling would be accomplished using two methods:Air/rotary techniques through the limestone horizon <br /> (limestone will also be spot-cored for testing samples) and coring techniques using wireline tooling and <br /> HQ(or similarly sized) coring tools. <br /> Fuel and Lubricants: <br /> Fuel will be stored in individual tanks on either the truck or the trailer. Equipment lubricants will be <br /> contained within the equipment they are lubricating.Any grease or small lubricant containers will be <br /> contained within the truck or secured on the drill trailer. <br /> In the case of a fuel or lubricant spill,the spill will be contained with an earthen berm or absorbent <br /> booms and absorbed using absorbent pads, powders,or dry earthen material.Contaminated products <br /> and soiled earth will be disposed of at an authorized facility in accordance with local, state, and federal <br /> regulations. Garfield County Landfill is one such authorized facility. <br /> Water, Cuttings Management, and Erosion Control: <br /> Drilling operations will be conducted using both wet and dry drilling techniques. Dry techniques(air and <br /> rotary)will produce cuttings at the collar of the drill hole.These cuttings will be kept at the collar or <br /> shoveled a few feet away from the collar. Cuttings will be kept and used for plugging the drill holes.Wet <br /> coring will employ the use of water to lubricate and cool the core drilling bit. Prior to the coring of a <br /> hole, a steel casing sleeve will be installed in the top section of the drill hole.The casing will extend <br /> down into the hole a few feet and will extend out of the hole a few feet as well.The casing above the <br /> surface will have an outlet on one side to allow returned water and cuttings to flow out of the casing in a <br /> controlled manner.The flow of returned water and cuttings will be directed into a holding tank with a <br /> volume of 500-1000 gallons.The water and cuttings will be allowed to settle in this tank and fill it up to <br /> the level of an outlet in the side of the tank. Once the water level reaches the tank outlet, it will flow <br /> into a second 500-1000 gallon tank, where the water and cutting fines will have additional time to settle <br /> and separate.Water in the second tank will be pumped out of the upper portion of the tank and <br /> recirculated down the drill hole as clean water for the coring process. Flocculants or other additives will <br /> not be used in the settling process. Water remaining in the settling tanks after the drilling process will be <br /> allowed to settle further and then pumped back into the 2500 gallon storage tank on site where it will <br /> be used as a dust suppressant in crushing operations. Drill cuttings and fines in the settling tanks will be <br /> emptied onto the ground near the drilling site and will either be used to plug the drill holes or will be <br /> disposed of in our fines pile on the northeast corner of our current bench area. <br /> 2 <br />
