<br />• EXHIBIT D (Revised 3-10-78) <br />77 3Nr~ <br />INTRODUCTION <br />A limestone quarry and cement manufacturing facilities <br />have been operated at this location since the late 1690's. <br />A new plant facility No.3 increased production in 1975, <br />vrhich has generally changed the limestone quarry operation. <br />The No. 1 plant has been mostly removed and the No. 2 plant con- <br />tinues to operate. About 1,500,000 tons of limestone raw materials <br />are required per year to supply Plants 2 and 3. Sandstone is <br />supplied from a small quarry in the floor of the limestone quarry <br />at an annual rate of 35,000 to 45,000 tons. Other raw materials <br />are purchased. <br />• The limestone formation lies relatively flat with the <br />Codell sandstone quarry floor sloping about 25 feet per 1,000 <br />feet to the southwest. The surface is gently rolling with a <br />dominant southward drainage into the Arkansas river. A 35.4 foot <br />average thickness of the better quality Fort Hays limestone rests <br />cn the Codell sandstone. Only the lower 8-12 feet of the overlying <br />Smoky Hi11 limestone and the Fort Hays is used. Oarying thick- <br />nesses of soil materials, gravels, or outcrop of Smoky Hi11 shale <br />make up the surface. <br />A major fault band at least 500 feet wide is indicated on <br />map pcc-1387 and extends from the south central portion of sec- <br /> tion 16 northwesterly. The entire formation drops douvnward from <br />. ;vest co east in steps across this fault. the fault band will not <br />
