You will be receiving a formal approval letter from our Denver office <br /> soon. Please read this letter carefully, as it contains several important items you must be made aware <br /> of. <br /> The details of the mining and reclamation plans under this 112c conversion have not changed <br /> significantly from the original ones for the 110 permit. The pit will still be mined about 10 feet deep, <br /> no groundwater will be exposed, and crushing-and asphalt batching will be allowed. Pit slopes are to <br /> be reduced to 10:1. Topsoil will be salvaged so it can be replaced during reclamation, the same <br /> revegetation plan will be used that was approved when the pit was CDOT's, and the reclamation costs <br /> now include weed control. <br /> Your plan was to increase your disturbance by three acres at'a time, and to reclaim three acres as the <br /> pit expands, so as to keep the disturbance limited. The reclamation costs account for reclamation to be <br /> performed on up to 10 acres, since that is approximately the present amount of disturbance and it is <br /> expected to remain constant. Please ensure that you limit the disturbed area(and include land used for <br /> stockpiling or equipment storage)to 10 acres. If more land is needed for your operation, you may <br /> revise the permit to increase the disturbed area. You may have to post markers or fences to prevent <br /> contract operators orisite from redisturbing reclaimed areas. <br /> There are knapweed infestations onsite, and though there is-presently not an adequate weed control <br /> plan, the bond amount must include costs for their treatment. I have included that in the new bond <br /> estimate,but you must now revise your permit to include a.weed control plan. (The cost for a 112c <br /> technical revision is 216.) Please contact your local weed control office for assistance in preparing a <br /> plan. I will be inspecting the pit in the coming months to help wrap up these changes, and would like <br /> to review a complete weed control plan with you. <br /> This letter is also your notice that the required bond amount has been increased. Enclosed is an <br /> updated reclamation cost estimate packet that includes the tasks mentioned above; as well as the <br /> mobilization costs and indirect costs for contractor overhead and profit. Please review this and;contact <br /> Office of Office of <br /> 1nor6—MinPc <br />
