<br />these maps in the permit. Please inform the Division where <br />these maps can be located, or submit new maps to the Division. <br />These comments are for your information and do not necessarily need <br />to be addressed by the operator: <br />5. Section 2.05.3 of the permit pertains to the operation plan of <br />the HG Mine. Since the mine site is in reclamation status, <br />this requirement does not necessary apply. However, the <br />operations plan in the permit does state the plan prior to <br />reclamation in 1986, and appears to be in compliance. <br />6. Sealing & Managing Mine openings was researched in the permit. <br />It appears that seven (7) monitoring holes remain. These <br />wells include LC2, LC3, LC1, UC1, UC2, UC3 and UC4. The first <br />two wells mentioned appear to be dry, while the remaining five <br />encounter aquifers. It appears that HG has adequately <br />addressed the sealing and plugging method for reclamation of <br />the monitoring wells. <br />7. I conducted a reclamation cost estimate for the HG mine. It <br />was difficult to locate information in the permit based on <br />current on site conditions, because most of the permit dates <br />back prior to 1986. I used various aerial photographs and <br />post-mining contour maps located in the permit. Based on this <br />information, the Division calculated a reclamation bond <br />liability of $55,835.00. Please note that the Division <br />currently holds $1,386,313.00 in bond money, indicating that <br />we have sufficient funds if needed. Various assumptions were <br />made to determine the worst case scenario, and they are as <br />follows: <br />a. Task #1 - I estimated a cost for any miscellaneous <br />backfilling and grading needed on site. This was <br />concluded from our conversation of some minor slumping <br />over the highwall area. Based on the minor disturbance, <br />I believe that 40 hrs. using a Cat D4H dozer is adequate. <br />This task totals $2,349.00. <br />b. Task #2 - DMG typically includes an estimate for <br />additional rill & gully repairs needed on site. I <br />estimated 20 hrs. using a Cat D4H dozer based on the <br />vegetation success at the site. This task totals <br />$1,174.00. <br />c. Task #3, #4, #5 - I included a cost for ripping existing <br />haul roads, light-use roads, and access roads based on <br />the information in Exhibit I. I re-verified the roads on <br />the aerial photographs as well as consulting the <br />existence of roads with you. Based on this information, <br />I estimated a cost to rip the roads using a Cat D4H dozer <br />with a 1-shank ripper at $3,769.00. <br />
