<br />January 7, 1987 <br />Page 4 <br /> <br />height of which will be approximately 45 feet. This open foot- <br />wall will not be recoiled or revegetated. In 2 or 3 areas where <br />the footwall will be 60-80 feet in height, raptor nesting areas <br />will be put into the rockwall. The DOW will be contacted for <br />their recommendations as to the appropriate size and height of <br />these raptor nesting areas. The bottom or the pit will be back- <br />filled to a slope of 3H:1V or flatter and will approximate the <br />existing rolling terrain. <br />In some areas where the footwall is 10 feet in height or less, <br />wildlife pathways will be constructed into the rock footwall. <br />These pathways will provide access for wildlife movement between <br />the upper and lower portions of the hogback; these pathways will <br />F ;~ be no more than 1,000 feet apart along the mined clay seams. If <br />~,~w~' necessary, the wildlife pathways will be cut into the rock foot- <br />~~~ wall with heavy equipment and possibly drilling and blasting. <br />The maximum slope will be 1.SH:1V with max length of 30 feet. <br />The sides of these cuts will be held at a 1H:1V slope. No top- <br />soil or vegetation will be replaced in these pathways. <br />Topsoilinq <br />Topsoil material will be stripped where available from the <br />advancing face and placed into topsoil stockpiles. After back- <br />filled material has been final graded, topsoil will be spread <br />to the same depth as stated in the current permit--from 3 to 5 <br />inches averaging 4 inches. <br />Fertilization <br />After recoiling the redistributed soils will be sampled and <br />tested to determine the quantity of supplemental nutrients that <br />are needed. Fertilizers will be added accordingly and spread as <br />recommended by the SCS or other soil specialists. Where <br />possible, fertilizer will be spread at the time of seeding and <br />blended into the top two to four inches of the soil by discing. <br />Revegetation Program <br />The soils will be prepared by discing, followed by either the <br />seed being broadcasted or drilled. If the seed is broadcasted, <br />the soil will then be harrowed. <br />The proposed seed mixture as recommended by the SCS is as <br />follows: <br />
