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 % 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 />00 <br />a� <br />a <br />December 28, 2414 <br />Colorado Division of Reclamation Mining and Safety <br />Gold Basin Mine, Inc. <br />Gold Basin Mine <br />Granite, Colorado <br />
