2. Reclamation Activities <br /> a. Site Preparation <br /> Site preparation will implement BMPs where soils or mined material are prone to erosion <br /> adjacent to stream channels. Other activities may include installing temporary water crossings, <br /> and establishing rock storage and equipment staging areas within the mine disturbed areas. <br /> b. Site Grading <br /> Disturbed areas including base of operation, stream channels and roads will be reclaimed to the <br /> approximate configuration illustrated on Figure F-2 To the extent practicable slopes of 2.5 (H) <br /> to 1 (V)will be established. Where possible, south facing mine disturbed slopes will be graded <br /> equal to or less than 3(H):1(V). If necessary, a rock rake will be used to prepare the disturbed <br /> graded surface for seeding. Exhibit E Attachment B provides representative BMPs to be used <br /> during mining and reclamation activities. Grading and related reclamation activities will be <br /> conducted annually. Gold Basin will reclaim mine disturbed areas in approximately equal areas <br /> disturbed by annual mining. Annual mine disturbance is anticipated to be less than l an acres. <br /> c. Scarifying <br /> Following site grading,the area will be scarified using a disc harrow. <br /> d. Topsoil <br /> Because topsoil is thin(less than 6 Inches), historical and current mining activities will not salvage <br /> topsoil. Alternative native growth materials will be used. <br /> e. Mulch <br /> Mulch will be applied at a rate of 1-2 tons per acre and crimped or tacked in place. <br /> f. Irrigation <br /> Irrigation will not be used during site reclamation activities. <br /> g. Fertilizes <br /> Fertilizers will not be used during site reclamation activities. <br /> h. Revegetation <br /> As necessary,mine reclaimed slopes steeper than 3(H):1(V)will be stabilized using BMPs.. <br /> Where possible,to enhance revegetation success, south facing slopes will be graded flatter <br /> QO <br /> r—1 <br /> December 28,2014 <br /> Colorado Division of Reclamation Mining and Safety <br /> Gold Basin Mine,Inc. <br /> Gold Basin Mine <br /> Granite,Colorado <br />
