8. Revegetation Success Criteria <br /> Areas will be deemed adequate when vegetation is established to control erosion and noxious <br /> weeds are not present in any significant amounts and all of the conditions of Rule 3.1.10 are met. <br /> 9. Monitoring Reclamation Success <br /> Monitoring reclamation on an ongoing basis will allow minor revisions to assure efficient and <br /> successful reclamation. The Operator plans to use the local NRCS office to assist in determining <br /> the ability of the reclaimed land to control erosion. If minor changes or modifications are needed <br /> to the seeding and reclamation plan,revision plans will be submitted to the Division, as required. <br /> It is hoped that the Division will provide assistance in evaluating the success of ongoing <br /> reclamation processes. All areas disturbed and reclaimed and any other important items <br /> regarding reclamation will be submitted in the required annual reports to the Division. <br /> 10. Reclamation Bond <br /> Reclamation activities during the worst-case scenario include highwall knock-down and grading <br /> the active mining area, topsoiling and seeding the active working areas (mining and processing), <br /> and seeding the tailings pond once the area is completely dried out. At the landowner's request, <br /> the gravel stockpiling area and site roads will remain un-reclaimed. Highwall knock-down will <br /> occur to a maximum 15-foot depth over 100 feet of hi hwall in the active mining area and will <br /> P g g <br /> result in —1,250 CY of material movement and grading. —670 CY of topsoil applied at a 2-inch <br /> depth will be laid across the maximum 2.5 acres of reclaimable disturbed area. Reclaimable <br /> disturbed area includes open mining areas, the processing area, and tailings pond. Fertilizer and <br /> weed-free mulch may be applied, as needed. <br /> The bond for the site will be based upon $2,500 per acre. As the site will have two acres open to <br /> mining plus an additional 0.5 acres of processing and tailings area, the site will have 2.5 acres of <br /> disturbance at any given time. Additional acreage may be disturbed but, at the landowner's <br /> request, will not be reclaimed and is not included in the disturbance area used to calculate a <br /> bond. Since a fraction of an acre is counted a whole acre by the Division, the bond will be 3.0 <br /> acres x $2,500.00 per acre = $7,500.00. <br /> Bancroft Placer Mine 4:nV I rnKW&Ao A1WX VIA A <br /> July 2020 D-4 <br />
