Mr. Paul Daggett, Mining Engineer <br />White River Field Office / <br />Bureau of Land Management v <br />220 East Market Street <br />Meeker CO 81641 <br />Dear Paul and Travis: <br />Mr. Travis Marshall, <br />Environmeal Protection Specialist' <br />CDRMS <br />101 South P Street, Suite 301 rSICE <br />Grand Junction CO 81501 <br />APR 25 2011 <br />?r- 2,00' 6 - 0 +4 (o C)M: ion of Rec13-m4 lion, <br />Mining and Safety <br />As we discussed on site last Tuesday, AMSO would like to bury dewatered drill cuttings under <br />our TM Pad and not truck them to the Rio Blanco County landfill as previously planned. There <br />would be no new disturbance, and burying the cuttings on site would reduce local road truck <br />traffic and other impacts. <br />We would dig a trench about eight feet deep to rock, parallel to and near the northern end of the <br />TM Pad. The trench would be about ten feet wide and about 200 feet long to accommodate the <br />drill cuttings we will generate. We would pile most of the excavated material on the north side <br />of the trench next to, but separate from, the wind-row of topsoil. We would use some of the <br />excavated material to make a short berm around the ends and south side of the trench for safety <br />purposes. <br />The cuttings would be dewatered as much as feasible before being put into the trench. The <br />cuttings would then be covered with at least two feet of the material removed from the trench <br />(we would keep the level of cuttings two feet below grade). The cuttings, the two feet of fill, and <br />the topsoil replaced for reclamation would provide an adequate root zone for plant growth. The <br />remainder of the material removed from the trench would be evenly distributed over the pad <br />during final reclamation. <br />We sampled the drill cuttings from different depths of our previously drilled core hole and had <br />those drill cuttings analyzed following the procedure established by Rio Blanco County. The list <br />of analyses is enclosed. The analyses showed the cuttings pose no environmental concern, and <br />the approval we received from Rio Blanco County to dispose the cuttings in their landfill is <br />enclosed. <br />Sincerely, <br />/?`, -4 <br />Roger L. Day <br />Vice President of Operations <br />
