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 to <br />catastrophic flooding in that portion of our county, the gravel within our permitted area <br />was quickly depleted, with much more required to repair the damage to our county roads <br />This 112 conversion is now required, and the life of the site will advance until 2022. <br />The depth of the salvaged topsoil to be used for reclamation is to be 3 -4 inches thick. The <br />topsoil for this site is to be located within the pit boundary to be used for reclamation of <br />areas depleted of sand and gravel. Each stockpile will be stabilized with a vegetative cover <br />of fast growing prosso millet if the need arises. <br />The thickness of the overburden ranges from one foot to five feet. The thickness of the <br />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 well as <br />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 resource <br />mined. <br />Mining will continue in the downward direction until the sand and gravel has been <br />removed, and that the loamy clay stratum beneath the sand and gravel is exposed. At this <br />point, mining is terminated in a downward direction. <br />A berm in the Northeasterly border of the pit will be maintained to prevent stormwater out <br />flow. <br />Measures taken to minimize disturbance to the hydrologic balance consists of the mining <br />operation to expose a minimal amount of surface area for mining at any given time. As <br />excavation continues the disturbed area is to be back sloped to mitigate runoff <br />possibilities. The lower area of the operation is flat and porous enough to slow any runoff <br />from the operation. The soil in the affected mined area should not present any reclamation <br />problems with standing precipitation due to its porous consistency. The land surrounding <br />the mine is range and the proposed future use is to be the same. <br />There will be no processing done on -site. No hazardous materials will be stored on site. <br />Refueling of Road and Bridge equipment will also take place off -site. <br />
