A water supply well was constructed in 1998 to supply water for the <br />offices and quality control lab associated with the operations. The <br />well is 178 feet deep and is finished in sand. A copy of the well log is <br />included as Exhibit 2. Wastewater is contained in a holding tank, <br />which is pumped and transported to final disposal by a State certified <br />and licensed contractor. <br /> <br />The site access is from 221 st Ave. An entrance road to the plant is <br />aligned with a new entrance road to the southern portion of the site. <br /> <br />Areas to be mined are cleared and grubbed and then stripped as <br />needed. Topsoil is stockpiled on site. Overburden is stockpiled or <br />used as backfill to reclaim completed portions of the mine. Sand and <br />gravel will be excavated from the active mining area and brought to <br />the processing area. <br /> <br />The site will be mined in phases. The progression of mining is <br />illustrated on Sheet 2 of 3, Phasing Plan. Restoration will begin as <br />phases of mining are completed. <br /> <br />No explosives will be used at the site. <br /> <br />9.) <br /> <br />Drainage, Erosion Control, Sedimentation, Dust, Access ContrOl and <br />Security: <br /> <br />Surface water drainage is directed to a Iow area within the excavation. <br />Collected surface water infiltrates into the underlying soils and/or <br />evaporates. Surface water drainage will not be directed off site. <br />Sedimentation may occur in the temporary ponding areas. These <br />ponds can readily be cleaned out by on-site equipment. <br /> <br />Erosion of finished slopes is minimized by backfilling to a minimum <br />slope of 4:1 and seeding and mulching. The berm has been <br />constructed to a minimum of 3:1 slopes and seeded and mulched. <br /> <br />Dust control has been implemented by hard-surfacing 221st Ave. from <br />the exit to US 169. The main entrance and exit roads to the plant <br />area are also hard-surfaced. Conveyors are used within the site <br />minimizing truck traffic on internal haul roads. Perimeter berms also <br />limit dust movement from the site. <br /> <br />Access control has been established by locking gates at the site <br />entrances and exits. The entire site will be fenced. <br /> <br />12 <br /> <br /> <br />
