Please supply proof of publication. <br />Proof of publication is included with this letter. <br />2. In the Mine Plan please clarify in Exhibit A that only 9.11 acres will be the maximum <br />disturbance. <br />Will Dolinar from William H. Smith and Associates has provided the revised Exhibit A to the <br />DBMS with the corrected maximum proposed disturbance of 9.11 acres. <br />3. Please state in the Mine Plan the estimated depth to which soil, suitable as plant growth medium, <br />will be salvaged for use in the reclamation process. <br />As depicted on the mining plan map, an estimated 8 inches of topsoil suitable as a plant <br />growth medium, totaling 9,845 bank cubic yards, will be salvaged for use in the reclamation <br />process. <br />4. Please state in the Mine Plan the thickness of overburden or quantity of waste rock, if any, to be <br />removed to reach the deposit. <br />The overburden depth varies at the site from approximately 3 feet to 4 feet below existing site <br />grades. The estimated spoil, as depicted on the mining plan map, is 409,260 bank cubic <br />yards. <br />5. In the Mine Plan specify the thickness of the deposit to be mined. <br />The sandstone formation material (Uinta/Green River formation) reaches depths of several <br />hundred to thousands of feet. The material will only be mined to a depth of approximately 60 <br />ft below original site grade. <br />6. In the Mine Plan please specify the dimensions of any existing roads that require significant <br />upgrades or proposed roads that will be used for the mining operation. <br />No existing roads will require significant upgrades to support the mining operation. Two <br />short access roads will be constructed to the site from the road, one for ingress and one for <br />egress from the site. These two access roads are depicted on the mining plan map. The <br />entrance access road will be about 15' long and 20' wide. The exit access road will be about <br />10' long and 20' wide. <br />7. In the Reclamation Plan please explain how the seedbed will be prepared to eliminate compacted <br />conditions (e.g., plowed, chiseled, disced). <br />The seedbed will be prepared by discing. <br />Cordilleran Compliance Services, Inc. <br />Grand Junction, CO • Denver, CO • Casper, VVY • Laramie, WY <br />Environmental Consulting Engineers and Scientists <br />
