To date a request for more information concerning compaction <br />requirements for the residential areas in A, E and F and a response to the Preliminary Adequacy Review <br />has not been forwarded to this Office. Given the current switch in personnel at Elam /Ephemeral this is <br />understandable but is causing some delay in the application process. DMG staff has some further <br />questions that must be answered in addition to those already presented to Elam /Ephemeral in order to <br />accurately calculate the cost for reclamation. Please respond to the following questions: <br />1) A review of the amount of overburden available on site indicates that there may not be enough to <br />backfill and compact the areas designated as A, E and F along with the other areas. Reclamation Map 6- <br />6 shows varying depths of overburden and it is difficult to ascertain exact volumes. Please suonly a <br />detailed soil balance sheet showine that there is enou>?h overburden to do all the reouired reclamation <br />within the permitted azea. <br />2) It is assumed that temporary site berms will be constructed of stripped topsoil and overburden. 1n <br />Area B no such berms are noted. Where will the overburden and topsoil be stored from this area? <br />3) The Mining Plan states that mining will begin in either Area A or B depending on "Mazket <br />Demands". In order to calculate the bond a firm commitment to a starting_Roint needs to be identified. <br />Concurrently, the sequence of mining needs to be identified. <br />If you need additional information, please contact me at the Division of Minerals and Geology, Grand <br />Junction Field Office, 101 S. 3rd St., Suite 301, Grand Junction, Colorado 81501, telephone no. <br />970.241.1117. <br />Sincerely <br />~_.. <br />G.
