3 <br />EXHIBIT D (Revised 3-10-78 )7j 3c{4 <br />• <br />~ alternate Cut No. 13 (not designated on map) vaill be prepared <br />east of the fault band near the new location of the crushing <br />~ facilities. Odd numbered cuts 15, 17, 19, 21 etc. will be <br />adjacent to new Cut No. 13. <br />Completion of Cut P1o. 20 (50 to 52 years or the year 2030) <br />will then deplete the west quarry and continuation of the <br />even numbered cuts can proceed in another location in the <br />east quarry. Additional exploration data will be required <br />to lay out specific cut sizes and locations in this east <br />quarry. Overburden removal and placement in adjacent cuts, <br />with production quarrying from alternate cuts is expected <br />to be performed in the same manner as already explained for <br />the west quarry. <br />Cuts No. 1 and No. 3 have up to 2 feet of the best topsoil <br />materials in the entire quarry. This grades into no recover- <br />able topsoil on Cuts No. 9 and No. 11 where shale is en- <br />countered at the surface. Topsoil and the better substitutes <br />will be stored on the fault zone, and the quarry perimeter <br />south of U.S. 50 until it can be moved back for final grading <br />after the cuts are refilled with overburden. The even- <br />numbered cut area has mostly gravels and shales at the surface. <br />(b) Earth Moving--In the future, top soil or substitute materials <br />can be moved around an adjacent open cut for direct deposition <br />on the filled cut to eliminate some storage and double handling. <br />. It is anticipated that scraper-type eeuipment will be purchased <br />
