'' <br />Mr. Scott Briggs <br />February 18, 1980 <br />Page -2- <br />2) P-D-2 - "all mining east of this line will be within <br />Tract A." Should this be Tract A-1. <br />3) P-D-5 - The 12° to 18° slopes would be 42:1 and 3:1. <br />This is considered level enough to save topsoil. <br />4) Please estimate how much topsoil will be removed and <br />stockpiled from the undisturbed land. <br />5) If the topsoil stockpiles are to remain for more than <br />2 years, they will need to be stabilized. How will this <br />be done? Where will the stockpiles be? <br />D. Exhibit E - Reclamation Plan <br />1) The experimental area appears to be located outside of <br />the permit area, please explain. <br />2) P-E-1 - Please state the approximate acreage for the <br />industrial site and wildlife area. <br />3) P-E-5 - Please show on the reclamation map approximate <br />locations of the benches and terraces and state what the <br />anticipated measurements and degree of slope will be. All <br />areas steeper than 2:1 should also be shown on the map. <br />4) Vertical walls and slopes in excess of 2:1 need to have <br />their long term stability addressed. If the highwalls are <br />stable enough, holes could be randomly created of various <br />sizes for plant establishment and wildlife use. This method <br />or some other similar method could help break up what would <br />other wise be anomolous features. <br />5) P-E-6 - Please supply a soil test on the processing fines. <br />Will these fines be hauled from the sand plant? <br />6) P-E-6 - The final grade must be determined and created prior <br />to replacement of 12-24 inches of fines since it appear solid <br />rock will underlie the fines. <br />7) P-E-7 - Please state the flow capacity of the drainage <br />ditches and how they are protected from erosion and siltation. <br />8) P-E-7 - How will a stockpond benefit a residential or <br />industrial area? <br />9) P-E-8 - Please describe in greater detail why it is not <br />felt that there will be slippage or movement of the plant <br />medium. The S.C.S. report states that this material has <br />a moderate to high erosion hazard. <br />10) What type of broadcast seeder will be used? <br />(cont'd) <br />
