Mount and Sorenson: <br />We are in receipt of your Adequacy Letter for the Rock Island Operation <br />110 Permit Application to re-mine some of the placer dredge tailing up the <br />Swan River. The following are our responses to your questions: <br />1. As directed, we have applied the 5 % Office Administration cost to the <br />Reclamation Cost w/ Contract Administration. This increased the Total <br />Reclamation Bond by approximately $528 (see attached revised Reclamation <br />Cost Estimate). <br />2. The maximum lace that might be excavated at any one time would be <br />perhaps 20 feet high and 200 feet long. Reducing such a slope from 1.3:1 to 2 <br />or 3:1 of unconsolidated material would be a task that could be accomplished <br />easily with a dozer in about 1 hour. A backhoe/front-end loader might even <br />reasonably accomplish the task in 2 hours. Hence, we have added $200 to the <br />Base Cost for this contingency. <br />3. You are wondering whether or not fuel will be stored at the site. There will <br />be no fixed above ground or below ground fuel, oil or grease storage tanks at <br />the site. On-site equipment will be fueled by a mobile fuel trailer that may or <br />may not park on-site. <br />
