Sherman <br />Executive Director <br />, / Ronald W. Cattany <br />N / Division Director <br />Re: Gallegos Pit, Permit M-1983-164, Conversion CN-1, Approval and Notice of Bond IncreaseSOUfCe Trustee <br />Dear Mr. Gallegos, <br />This letter is to inform you that I have approved the conversion application (CN-1) that converts your <br />110 permit to a 112c permit. 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 hatching 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 onsite 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 />P4 <br />??4 <br />Office of Office of <br />Mined Land Reclamation Denver Grand Junction • Durango Active and Inactive Mines
