a <br />EXHIBIT D (Revised 4-28-78) <br />' (a) and (b) Description of the methods of minine and earth- <br />' moving to be employed in each stage of the operation as <br /> related to any surface disturbance of affected land. <br /> Different methods and equipment have been used during <br /> the lust 50 years this quarry has operated, and will likely <br /> involve changes in technology and equipment during the <br />' ne..t 50 years. Current operation involves drilling holes <br /> and placing explosives to loosen and break overburden for <br />' moving with dragline equipment. Blasting is also required <br /> in order for dipper-type shovels and front-end loaders <br />' <br /> to load quarr,v type haul tracks with the cement plant <br />' raw materials. Front-end loaders and bulldozers ar= <br /> aloo used to load trucks, clean up around the operations, <br />' build ru;+ds, grade, e6c. A road grader and water truck are <br /> <br /> utilized to maintain access roads. <br />' l <br /> Shal <br />ow calcareous soils, limestone and shale out- <br />' croppings make it impractical to recover soils over much <br /> of the quarry area, An exception is the geology at the <br /> north end of the A-band quarry where a Swale east of <br /> the A-band ridge contains 2 to E feet of recoverable <br /> il <br />i <br />d <br />A <br />i <br />k <br /> so <br />s stockp <br />le <br />t.o the east. <br />s recoverable so <br />l poc <br />ets <br />' are encountered in future quarry operations, they will be <br /> :;eve+l. 4N~~c+l.l,cred :surface shales will provide limited amounts <br /> of acceptable soil substitutes for reclamation purposes. <br /> Refer to the Reclamation Plan for additional information. <br /> <br /> <br />
