Pages in the permit application have been updated to reflect the <br />changes as well. Two copies of all modified materials are included in this package. <br />1. The location of the main entrance to the Haldorson Sand and Gravel Mine in <br />longitude/latitude is 038° 30' 8.89"N / 107° 56' 3.36" W. <br />2. Since Map C-1 is busy and some detail in the map is lost or hard to discern, Map C-1 has <br />been split up into two separate maps. Map C-lA consists primarily of the natural <br />features. Map C-1 B consists mostly of manmade features. We believe that splitting the <br />map into these two maps will make it easier to discern all detail. The area of the previous <br />permit which has been removed has also been added to Map C-1 A in order to compare <br />the current permit area with the proposed permit area. <br />3. Temporary berms will always be placed around the perimeter of the mining operation in <br />order to create a screen for visual impacts and noise. Temporary berms will always be <br />placed around the active mining Phases on all sides. These berms will be 8 feet high with <br />a 3H:1 V slope except for the internal south berms, which will only be 2 feet high. A note <br />to describe this has been added to Map C-2, in order to clarify this issue, however <br />temporary berms are not shown on this map as the map would become too cluttered if the <br />berms were to be shown at every location. <br />4. The ratio for the proposed temporary seed mix has been added to the Mining Plan. The <br />percentage of each species will be the same and will total I S pounds per acre of <br />temporary seed mix which will be applied to the topsoil berms and temporary stockpiles. <br />This results in 5 pounds of live seed per acre each of slender wheatgrass, western <br />wheatgrass, and thickspike wheatgrass. <br />
