3 DESERADO MINE <br />BLUE MOUNTAIN ENERGY <br />3607 County Rd. 65 <br />Rangely, CO 81648 <br />(970)675-4300 <br />fax (970)675-4399 <br />January 11, 2016 <br />Mr. Clayton Wein <br />Division of Reclamation, Mining and Safety <br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br />RE: Professional Certification for the Coal Processing Waste Banks <br />Deserado Mine - Permit No. C-1981-018 <br />Dear Clayton: <br />RECEIVEr) <br />Division ofRecia <br />Mining & Sai ation, <br />During the fourth quarter of 2015, qualified persons working under my direction and I conducted <br />a series of compliance inspections on the active coal processing waste banks located within the <br />Deserado permit area. These inspections were conducted roughly on a bi-weekly basis. <br />I am a professional engineer registered in the State of Colorado and my experience fulfills the <br />requirements of the Colorado Surface Coal Mining Reclamation Act. <br />The purpose of these inspections and subsequent certification is to ensure proper construction of <br />the refuse piles and to satisfy the requirements of Rule 4.10.2 of the Colorado Mined Land <br />Reclamation Board. <br />INSPECTION OF ACTIVE AREAS 2-3-4 and 5A <br />There are no apparent points of seepage, or indications of slope failure on the active piles. The <br />surface drainage facilities were adequately maintained and were working properly to convey <br />surface runoff. Sediment control structures need periodic maintenance and are cleaned out as <br />conditions warrant. <br />The following maintenance work was completed since the last quarterly report: <br />1. Refuse was placed, spread, and compacted on Areas 2-3-4 and 5A during the quarter. <br />2. A winter stockpile was started on Area 5A. <br />Our permit requires no sub -drain system, as geotechnical investigations for the disposal site <br />revealed no groundwater present. <br />Refuse is spread and compacted in lifts not exceeding 24" in depth. Typically refuse is spread <br />much thinner producing 6" to 8" lifts. <br />
