' thus minimizing the amount of wind erosion. At present, after corn is <br /> ' harvested at the site in the Autumn, the corn stocks are plowed under and <br /> the ground surface is allowed to remain unvegetated. This is the same <br /> ' practice as is utilized on most other farms in the area. After a portion <br /> of the site has been returned to a farmable condition the ground surface <br /> ' will be at a lower elevation than the original grade. Because of this , it <br /> ' is expected that the amount of material picked up by the wind will be less <br /> after crops are harvested than at present where the ground surface is <br /> higher and more directly affected by the wind. The four foot high berms <br /> to be constructed around the perimeter of the site will be vegetated as <br /> ' will be vegetated as will be discussed below, during the first growing <br /> ' season after construction of those berms to minimize the amount of bare <br /> soil subject to wind erosion. <br /> ' The gravel materials which will be processed through the crusher at the <br /> ' site will be in a moist condition. This should result in a much lower <br /> production of dust than if the material were dry. The proportion of rock <br /> tdust generated in the crushing operation is normally insignificant compared <br /> to the quantities of overburden handled at the site. Any stockpiles of <br /> ' overburden at the site which must be constructed will be seeded as soon as <br /> tpossible to minimize dust generation. <br /> ' The only real consideration regarding safety which applies to the site is <br /> the possibility of persons being injured by falling into the pit itself <br /> twhile mining operations are being conducted. The cut slopes in gravel <br /> will be maintained so that they are not steeper than 2: 1 (horizontal to <br /> ' vertical ratio) . Places where overburden cuts will not naturally assume <br /> ' a 2: 1 slope they will be benched back from the top of the gravel in five <br /> ' -24- <br />
