Randy McClure/M- 1977- 215/TR -22 <br />June 7, 2013 <br />Page 3 <br />Waste Rock Storage Facility at 9400 Portal: Add 3.2 acres for placing and contouring additional waste <br />rock from 9400 decline. <br />History: The 9400 decline and disposal of associated waste rock were approved under TR -18 in 2011. <br />Additional land is required to accommodate future volume of waste rock from the decline. The 3.2 acres <br />of land was already disturbed by the previous operator, and was reclaimed. <br />Description: This TR -22 approves adding 3.2 acres for permanent placement of waste rock, in a pre - <br />disturbed location adjacent to the existing waste rock disposal area. A new 9400 portal access road will <br />be constructed along a different alignment on the dump face. <br />Mining Plan: The footprint of the additional affected area will be stripped of topsoil for later use in <br />reclamation. Waste rock will be contained in the defined area. Sediment controls will be used. The 3.2- <br />acre footprint of this addition was pre- disturbed, so there is no increase in affected area. <br />Reclamation Plan: The outslope of the waste rock disposal area will be graded to a maximum gradient of <br />2:1, final sediment controls will be established, topsoil will be replaced and the affected area seeded. Due <br />to the required slope reduction, topsoil replacement and seeding, there is an increase in reclamation costs. <br />Summary: All portions of the technical revision are approved. Throughout all phases of these changes, <br />the operator will document the progress of each installation, and provide as -built drawings and <br />photographs; engineering certifications will be provided as necessary. <br />The approved mining and reclamation plans require that the operator must also salvage available topsoil <br />and growth medium, protect it in stockpiles until it is used for reclamation, and control noxious weeds. <br />Financial Warranty: The operator has posted a total of $128,959 in financial warranty for this permit. The <br />additional financial warranty required for reclaiming the additional disturbance is $30,292. The updated <br />reclamation costs are shown in the enclosed packet. Please contact this office if you see any errors or <br />omissions in these reclamation cost figures. <br />The additional financial warranty should be submitted directly to the Division's surety specialist, Barbara <br />Coria, in the Denver office. The revision will not become final until the bond is approved by the <br />Division. Please note that the additional bond must be submitted within 60 days of this letter. <br />If you have any questions, I may be reached at the Division's Durango Field Office: 691 CR 233, Room <br />A -2, Durango, CO 81301; telephone 970 - 247 -5193. <br />Sincerely, / <br />Bob Oswald <br />Environmental Protection Specialist <br />Encl: TR -22 bond recalculation <br />Ec(w /o encl): Russ Means, DRMS Grand Junction <br />Barbara Coria, DRMS Denver <br />(c: \13 -06 docs\Bulldog TR -22 appr &fw /rco) <br />
