<br />about 2 years to mine each area. Before mining the gravel deposits we will <br />salvage stumps and trees and stockpile these along the boundary for <br />reclamation use. We will then strip a minimum of 6" topsoil (growth medium) and <br />stockpile adequate amounts along the length of the south and west boundaries. <br />We will then strip overburden material and stockpile at the south and west <br />boundaries separate from topsoil stockpiles. We will take approximately 7 years <br />to complete the mining of this entire area. Slope reclamation should be <br />completed within 10 years. We will maintain 2H:1 V slope highwalls while mining. <br />Mining and reclamation will be performed to standards set by BLM contract <br />COC 64651 and in the attached "Proposed Method of Operation" submitted to <br />BLM prior to the signing of the above contract. <br />The soils in this area are classified as Ustollic Haplargids, fine-silty, mixed mesic. <br />Basically these soils are deep, well drained soils which overlay the gravel <br />deposits. The pH of this soil is neutral and there are no salts present that will <br />affect plant growth. Depth of the overburden ranges from 10' to 20'. The gravel <br />deposit under the overburden runs approximately 50' deep with shale deposit <br />beneath. <br />The primary and secondary commodities to be mined are Class 6 roadbase <br />and Class 2 roadbase. Other types gravel will also be extracted as needed. <br />These materials will be used primarily for roadbase. Secondary use is <br />structural fill, landscaping, filtering, etc. <br />I have bolded the items that are changes or additions to the current Mining Plan. Our <br />current reclamation plan should stand as is. I am enclosing a copy of the BLM contract <br />and "Proposed Method of Operation" submitted to BLM. I believe you already have <br />these, but wanted to make sure. We have tried to make sure the mining/reclamation <br />plan presented to BLM and the mining/reclamation plan presented to DMG are in line <br />with each other while meeting each agency's specific requirements. <br />Regarding Item 3 -The west working face highwall has had overburden pushed off it and <br />is reduced to the approved 2H:1 V grade per John Gilleland. <br />Regarding Item 4 - C & J Gravel Products, Inc. commits to notifying DMG prior to <br />affecting Phase 2, so the reclamation cost estimate can be recalculated to account for <br />any additional cost that may be associated with mining of that phase. <br />Regarding Item 5 -This was resolved with the prior submission of financial warranty to <br />the State of Colorado. <br />I hope this answers all your concerns. Please contact our office if you have any <br />questions. <br />Sincerely, - <br />.ly~~L~~~C,~„ ~U <br />J Gilleland "'T <br />O ice Manager <br />
