STATE OF COLORADO <br />Roy Romer, Gove <br />DEPARTMENT OF NATURAL RESOURCES <br />MINED LAND RECLAMATION DIVISION <br />FRED R. BANTq, Dlrsetor <br />January 15, 1988 <br />Mr. Milliam T. Davis <br />1390 Ash Street <br />Denver, Colorado 80220 <br />Re: Notice of Intent No. X-87-202-00, Drill Hole Abandonment Report and Final <br />Reclamation Report <br />Dear Mr. Davis: <br />The above referenced reports have been reviewed. Both are acceptable to the <br />Division, although some questions arise from the Drill Hole Abandonment Report <br />in regard to Drill Hole No. 8. I interpret the report on this hole to <br />indicate a TD of 90 feet, the top of a water bearing zone at a depth of <br />75 feet, and cement plugs to have been placed between depths of 3 feet and <br />10 feet and between depths of 65 feet and 90 feet in the hole. Rule 4.07.3(2) <br />of the Regulations of the Colorado Mined Land Reclamation Board for Coal <br />Mining requires the sealing of water bearing zones not exhibitin_ artesian <br />flow at the surface with solid cement or other suitable media extending <br />20 feet above and below the zone. Accordingly if the top of the water bearing <br />zone was at 75 feet, the hole should have been sealed with cement or other <br />media up to a depth of 55 feet. The questions the Division has, therefore, <br />are 1). was the water level in the hole or the top of the water bearing zone <br />at 75 feet and 2). were drill cuttings or sane other material used to fill <br />the hole between depths of 10 feet and 65 feet? <br />Sincerely, <br />J~ti~ C ~~t~ <br />James C. Stevens <br />Reclamation Specialist <br />JCS/bdc <br />4703E <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203-2273 Tel. (303) 866-3567 <br />
