The next area to be mined is the portion of Phase II that lies <br />west of the Phase I pit and south of the Intermittent Ditch. Your operation appears to be in conformance with the <br />approved mining plan, and moving into the next mining phase does not require a revision to the permit. <br />You stated that the north, east and south slopes of the Phase I pit were sloped as they were mined, presumably <br />because they are in their final locations. Can you clarify whether the gradient of those slopes is the gradient <br />required in the final reclamation plan? If so, that reclamation cost may be removed from the bonded liability. I will <br />calculate the total bond amount, but will also review the cost figures provided with your letter. I will send the <br />revised bond amount soon, under separate cover. Please be reminded that upon notification of a bond increase, an <br />operator has 60 days to provide the necessary additional bond. <br />Thank you for the information. If you have additional questions, I may be reached at the Division's Durango field <br />office: 701 Camino del Rio, Room 125, Durango, CO 81301; telephone 970-247-5193. <br />Sincerely, <br />Bob Oswald <br />Environmental Protection Specialist <br />Ec: Bruce Humphries, DMg <br />C:\del norte west phase2 fw/rco <br />Office of Office of Colorado <br />Mined Land Reclamation Active and Inactive Mines Geological Survey <br />
