EXHIBIT D <br /> MINING PLAN <br /> PICKENPAUGH GRAVEL PIT (M-1978-078) <br /> Operation commenced 1978 and was initially scheduled to terminate in 2015. Due <br /> to catastrophic flooding in that portion of our county, the gravel within our <br /> permitted area was quickly depleted, with much more required to repair the <br /> damage to our county roads. This 112 conversion is now required, and the life of <br /> the site will advance until 2022. <br /> The depth of the salvaged topsoil to be used for reclamation is to be 3-4 inches <br /> thick. The topsoil for this site is to be located within the pit boundary to be used for <br /> reclamation of areas depleted of sand and gravel. Each stockpile will be stabilized <br /> with a vegetative cover of fast growing prosso millet if the need <br /> arises. <br /> The thickness of the overburden ranges from one foot to five feet. The thickness of <br /> the sand and gravel to be mined varies from six to twelve feet. <br /> Major components of the mining operation consists of the mining pit, haul road, as <br /> well as overburden, topsoil, and gravel stockpiles. <br /> No water will be used in conjunction with mining operation. <br /> Mining will continue in a Northwesterly direction. Sand and gravel will be the only <br /> resource mined. <br /> A berm in the Northeasterly border of the pit will be maintained to prevent <br /> stormwater out flow. <br /> Measures taken to minimize disturbance to the hydrologic balance consists of the <br /> mining operation to expose a minimal amount of surface area for mining at any <br /> given time. As excavation continues the disturbed area is to be back sloped to <br /> mitigate runoff possibilities. The lower area of the operation is flat and porous <br /> enough to slow any runoff from the operation. The soil in the affected mined area <br /> should not present any reclamation problems with standing precipitation due to its <br /> porous consistency. The land surrounding the mine is range and the proposed <br /> future use is to be the same. <br /> There will be no processing done on-site. No hazardous materials will be stored on <br /> site. Refueling of Road and Bridge equipment will also take place off-site. <br />
