Please clarify the intended use and what volume of the overburden <br />will be used in reclamation and provide an estimate of the haul distance required to replace the <br />overburden during reclamation to its intended destination. <br />- Response Adequate <br />3) Please clarify on a map where topsoil and overburden will be stockpiled for Stages 3A, 313, 4, 5 and 6. <br />The map provided with the April 23, 2009 response indicates the locations of approximate <br />overburden stockpile locations for each stage. Per Rule 3.1.9(1), where it is necessary to <br />remove overburden in order to mine the construction material, topsoil shall be removed and <br />segregated from other spoil. If such topsoil is not replaced on a backfill area within a time <br />short enough to avoid deterioration of the topsoil, vegetative cover or other means shall be <br />employed so that the topsoil is protected from erosion and is in a useable condition for <br />reclamation. Please provide a map that clearly identifies where the topsoil and overburden <br />will be located for mine stages 3A, 3B, 4, 5 and 6. <br />Office of office of <br />Mined Land Reclamation Denver • Grand Junction • Durango Active and Inactive Mines
