<br />1313 Sherman Street, Room 215 <br />Denver, CO 80203 <br /> <br />December 3, 2014 <br /> <br /> <br />Graham Roberts <br /> <br />Trapper Mining, Inc. <br /> <br />P.O. Box 187 <br /> <br />Craig, CO 81626 <br /> <br /> <br />RE: Trapper Mining, Inc., Permit C-1981-010 <br /> MR221; Adequacy Review <br /> <br />Dear Mr. Roberts, <br />The Colorado Division of Reclamation, Mining and Safety (Division) received MR221 on December 1, <br />2014 and deemed the application complete on December 3, 2014. The Division has reviewed the <br />proposed revised Blast Summary Form and permit text. Listed below are several items regarding the <br />Blast Summary Form that will need to be addressed prior to the approval of MR221. <br />1. The location of the blast is reported by indicating the pit in which the blast occurs. The Division <br />believes a better practice would be to report the specific location of the blast by indicating the <br />coordinates of the blast hole that is closest to the nearest dwelling, school, church or community <br />or institutional building either not located in the permit area; or not owned nor leased by the <br />person who conducts the surface coal mining operations. The blast summary form should be <br />updated to allow for a more precise recording of the location of the blast. <br /> <br />2. The current blast summary form depicted as Figure 3.4-3 in the permit includes a blank sketch <br />form. Trapper also records details of each of the drilled blast holes that includes; what row a hole <br />is in, the hole column number, the depth, water level, drilled depth and the weight of explosives <br />placed in each of the holes. The updated form submitted with MR221 does not include a copy of <br />the sketch form. The currently approved Figure 3.4-3 does not include a copy of the form used to <br />record the detailed information recorded for each drill hole. Does Trapper intend to update the <br />page used to sketch the blast pattern required by Rule 4.08.5(7) and (8)? Please include a copy of <br />the sketch form as part of Figure 3.4-3. Also, a copy of the form used to record the details of the <br />drilled blast holes should be included in the revised figure 3.4-3. <br /> <br />3. The blast summary form does not include a space to record if mats or other protections were used <br />in conjunction with a blast. Please revise the form to include a space to indicate if these items <br />were used. <br /> <br />This concludes the Divisions review of MR221. The decision date for this revision is December 13, <br />2014. If you need additional time to address the Divisions concerns, please request an extension of the <br />decision date.
