the need for drill pad leveling. At some sites, a small amount <br />• of dozer work may be aecessazy to create a level, flat surface <br />necessazy for drilling activities. Where leveling is necessazy, <br />a strip approximately 40 feet wide and 100 feet long <br />(approximately 0.1 acres) will be disturbed. Maximum cuts will <br />be held to 8 feet or less is height. All topsoil xill be removed <br />from those sites where grading is necessazy and stockpiled in <br />wind rows along the upper and lower sides of the pad for eventual <br />replacement and revegetation. Then a level pad will be dozed <br />within the stripped area. With the exception of mud pit <br />excavation, no other topsoil removal or earth work is planned. <br />Each drill site will be equipped with 2 mudpita for <br />containment of drill cuttings and drilling fluids. Each pit will <br />be a maximum of 20 feet long, 15 feet wide and ,6 feet deep (67 <br />cubic yards) and will be excavated with a backhoe or dozer. <br />Topsoil material will be excavated first and will be stockpiled <br />separately from the noasoil material. All excavated material <br />will be stored immediately adjacent to the pits for eventual <br />replacement and revegetation. Mudpit excavation at each Bite <br />will remove approximately 22 cubic yards of topsoil and 111 cubic <br />yazds of aonaoil material. <br />4. Drilling: All drilling and coring will be accomplished <br />using mud, foam or air lift methods with model 524 Portadrills or <br />like equipment. Water aeceseazy for drilling activities will be~ <br />hauled using a 3,000 gallon or similar size water truck. This <br />• water will be hauled from the Raton Creek Mine facilities or <br />other available water source neaz the drill sites. Drill <br />cuttings and fluids will be contained in the mudpita or in the <br />immediate vicinity of the drill sites. Each hole will be <br />geophysically logged using standazd electrical induction, natural <br />gamma and caliper techniques. Logging equipment will be housed <br />in a van-type truck. <br />5. Drill hole abandonment: During drilling activities, <br />each hole will be monitored to detect any water producing zones <br />and/or aquifers. Upon completion, each hole will be abandoned <br />utilizing abandonment drill mud and drill cuttings is areas where <br />no aquifers were encountered. All aquifers will be sealed with <br />grout extending 20 feet above and below the limit of the water <br />producing zone. Abandonment fluid and drill cuttings will be <br />placed in each hole to within 30 feet of the surface. A cement <br />plug will be placed from that point up to approximately 3 feet <br />below ground level and the remainder of the hole will be filled <br />with soil material. Each hole will be mazked by placing a metal <br />stake or pipe which protrudes through the surface for surveying <br />of its exact location and future hole identification. <br /> <br />6. Drill site rehabilitation: All mudpita will be allowed <br />to dry prior to backfilliag. When dry, they will be filled in <br />with noasoil material first and then the topsoil will be replaced <br />and the site will be graded to its original configuration. Those <br />sites which will require drill pad leveling will be regraded <br />after completion of drilling to their approximate original shape <br />
