drilling to achieve maximum trail width of 12 feet. In the event additional <br />trail is necessary, Northfield projects less than 500 feet of new trail per site <br />location. <br />Ephemeral streams are not in the vicinity of the proposed exploration. <br />Exploration activities will occur under weather conditions that will avoid <br />rutting and unnecessary vegetation disturbances along access trails and <br />exploration site. <br />Two of the proposed drill sites are located in areas of flat terrain to <br />avoid the need for drill pad leveling. Minor leveling may be necessary at site <br />NF-03. Each drill site will be approximately 45 feet wide and 100 feet long or <br />less than 0. i acre. Total disturbance for all exploratory activity will be <br />approximately 0.3 acres. The drill pad site will be prepared by stripping 3-12 <br />inches of topsoil with either a dozer or backhoe and stockpiling the topsoil. <br />The temporary topsoil stockpile will be placed upgradient to divert surface <br />storm water from the exploration site. A containment pit will be constructed <br />with a backhoe to collect drill cuttings and foam at each location with <br />dimensions of 2 feet wide by 10 feet long by 4 feet deep. All pit disturbances <br />will be contained within the 45 x 100 square foot drill pad. <br />Drilling will be performed with a Gardner Denver 15W, or similar <br />equipment, implementing airlift methods requiring foam injection. Drill hole <br />diameter will be six inches. Drilling water will be purchased in Florence, CO <br />and hauled to the site in a 3,000 gallon water truck. A van-type geophysical <br />logging truck will run standard natural gamma, caliper and density logs on <br />each completed drill hole. Access to and from the drill site will include <br />drilling and supervisory personnel via a 4x4 pickup truck. <br />Upon completion of each drill hole, the hole will be sealed to within 10 <br />feet of the surface with abandonment fluid and drill cuttings. During drilling, <br />each hole will be monitored to detect any water producing zones. Any <br />significant production zone, production equal to or greater than three gallons <br />per minute, will be sealed with cement grout extending 20 feet above and <br />below the limits of the estimated production zone. A cement plug will placed <br />above the abandonment fluid up to approximately three feet below the <br />ground surface. Soil and drill cuttings will be used as fill for the remaining <br />distance along with a metal stake, protruding through the surface for further <br />identification. Sealing will occur within 30 days of drill completion. In the <br />event a site is suitable to establish as a project monitoring well, the well will <br />be constructed and permitted according to State Engineer's Office regulation <br />for monitoring wells. <br />After completion of exploratory and sealing activities, the site will be <br />graded to approximate original contours. The pit will be allowed to dry prior <br />Yo backfilling with nontopsoil material. After the pit is backfilled, topsoil will <br />be placed to return the area to approximate original contours. Stockpiled <br />topsoil and drill cuttings will be distributed over the disturbed area in <br />3 <br />
