time. When the operator wishes to develop the northern deposit,the necessary application will be <br /> made to the DRMS. <br /> Additional Concerns—Security. Stormwater Control, Weed Control <br /> Throughout the life of this operation, erosion and presence of noxious weeds will continue to be <br /> monitored on all disturbed areas and addressed in a timely manner. <br /> The operator will install and maintain adequate stormwater controls for all affected areas of the site, <br /> including the quarry and operations pad areas, roadways, above-quarry slopes, topsoil stockpiles, and <br /> overburden cells. These controls may include earthen dams, culverts, ditches or diversions, and wattles <br /> or silt fence, as appropriate. See the Exhibit C maps for locations of the stormwater controls. <br /> The site will be kept secure by a single locked and gated entrance. The areas above the highwall will <br /> contain signage and/or physical barriers to deter accidental falls. <br /> Reclamation—Overburden and Topsoil Handling Reve eta <br /> Native topsoil is present throughout most of the undisturbed portions of the expanded permit area, <br /> though depths vary. Topsoil that is stripped prior to disturbance will be placed in one of the following <br /> areas: on the permanent overburden disposal cells, on the outslope of the expanded staging and <br /> stockpile area, on the new surfaces of the sloped areas above the expanded highwall, or placed in <br /> stockpiles for later use in reclamation. Topsoil will be spread on reclaimed surfaces at a depth of 3 to 6 <br /> inches. All areas where topsoil is placed, including the topsoil stockpiles, will be seeded with the <br /> approved revegetation seed mix at the approved rates. (Please see the Exhibit E reclamation plan for <br /> revegetation details.) <br /> Conclusion of Mininp, <br /> At the conclusion of the operations, all areas and features of the site will be fully reclaimed. This means <br /> the quarry will have stable, benched highwalls; slopes will be topsoiled and revegetated (excluding in- <br /> quarry surfaces with exposed obsidian); earthen stormwater controls will remain as permanent <br /> structures; roadways will be either stabilized to remain as permanent, or reclaimed by ripping followed <br /> by topsoiling and seeding; all stockpiled topsoil will be spread and seeded; all product stockpiles will be <br /> removed; all equipment and supplies will be removed; and the benches and operations pad area will be <br /> ripped, topsoiled and seeded. See Exhibit E for reclamation plan details. <br />
