The Division <br />has received formal objections to your Amendment application; therefore the Division is required to <br />make a recommendation [o the Mined Land Reclamation Board (',viLRB) three working days prior to a <br />Pre-Hcarino Meeting. This meeting has bucn scheduled for March 3, 2005; therefore, the <br />recommendation must be issued by February 25; 2005. The Division requests that your response to the <br />following adequacy review concerns should be received by the Division by February 18, 2005 in order <br />to sivc the Division some time to review the responses. <br />The Division's comments/concems are as follows: <br />I. Exhibit C -Pre-Mining and Mining Plan Maps <br />a) Since this application is an amendment to an existing permit, M-2000-b1G, the Riverbend <br />Operation, and will incorporate a second active pit, ~t-198S-088, the Fort Lupton Pit, into <br />the amended azea, the Division is requesting that the applicant provide a map showing the <br />boundaries of the two currently permitted sites and their correlation with the areas to be <br />incorporated into the Riverbend permit through the amendment process. This could be <br />done by adding the requested information to the current Exhibit CI Pre-Mine Map. <br />h) The legend on the Exhibi[ C3 Mine Plan Iefap indicates that the purple dashed line with hco <br />dots between each dash represents lateral ditches. In dte northeast comer of Phase 3 onYhis <br />map there are pttrple dashed lines with only one dot between each dash. What does this <br />symbol represent? <br />c) An examination of the Mine Plan Maps shows several locations, especially within Phases 4 <br />and 6, where the topsoiUoverburden stockplcs are located within 20 or 30 feet of the South <br />`~~nce ac P.fice M ColoraCo <br />nn:~etl Land Rccarnetion n<riee and ~~»: d•.,. m~oc.
