Section 3.02.2 Determination of Bond Amount <br />65. Attached is the Division's reclamation cost estimate for PR-12. The estimate is comprised of eight <br />tasks (a summary sheet and tasks 251-257) and represents an increase in liability of $45,039.00. This <br />estimate included the transfer of three exploration holes (BRL-1-03-01, BRL-1-08-01 and BRL-1-08- <br />04), drill pads, light use roads, topsoil replacement and reseeding from the Bowie No. I Mine permit <br />into the Bowie No. 2 Mine permit. The original Bowie No. I Mine revisions were TR-41 and TR-49. <br />The Division's estimate is more than the one submitted by BRL because the Division updated the costs <br />for the tasks from TR-41 and TR-49 in the PR-12 estimate. Please inform the Division in writing <br />whether or not this estimate is acceptable to BRL. <br />This issue is resolved. In the June 1, 2010 submittal, BRL accepted the reclamation cost estimate. <br />Section 4.20 Subsidence Control <br />66. Under Rule 4.20.2, please provide documentation that owners of property, including structures, and <br />residents within the area above the underground workings and adjacent areas have received the <br />mining schedule as described in Rules 4.20.2(1), (2) and (3). <br />This issue is resolved for now. In a separate July 8, 2010 submittal, BRL provided a copy of the BLM <br />notification letter. BRL has chosen to wait to notify the owners of the Pitkin Mesa Pipeline Company <br />concerning their pipeline and Delta County concerning the Steven's Gulch Road. The Division will <br />add a stipulation to the PR-12 proposed decision that will require the future submittal of <br />documentation that these mining schedule notifications had been sent according to Rule 4.20.2. <br />General Comments Regarding Maps <br />67. Map 07 - Geology <br />A. The Legend provides a symbol for `B-Seam Projected" workings, but these workings <br />have not been depicted on the map. Please revise the map to represent the B-Seam <br />Projected workings, including the 1 West Mains. <br />B. There are areas of red and green cross-hatching shown within the permit boundary, <br />but the Legend does not explain these symbols. Please add the red and green cross- <br />hatching symbols and explanations to the Legend. <br />C. The source of the geologic base map is not identified -please provide a reference to <br />the base map used to develop Map 07. <br />D. On the Strike and Dip symbols shown on the map (2) and Legend, the Dip is <br />mistakenly given in % The numbers are correct, but the unit should be Degrees <br />Please modify each of these symbols accordingly. <br />This issue is resolved. Map 07 was revised in the June 1, 2010 submittal. However, the source of the <br />geologic base map is not known. <br />68. Maps 08 and 08A - Geologic Cross Sections <br />14
