EXHIBIT D -Minim Plan <br />a) This is a dry pit. Mining will commence in the northwest corner of the property <br />by removing vegetation, topsoil and a~ overburden at the highest altitude. <br />Topsoil will be stockpiled on the north and overburden on the west. Gravel <br />extraction will then begin by starting at the southeast side of the cleared area and <br />proceeding back into the slope to create a bench with a maximum high wall of <br />about twenty feet. When all gravel is removed from the entire bench to the <br />topsoil and overburden stockpiles, a new bench will be started about twenty feet <br />down slope on the southeast edge of the first bench. The high wall of the first <br />bench will be graded by cut and fill and using any available overburden. Topsoil <br />will then be spread on the final graded slope. Mining will progress down slope to <br />the east and south in successive benches until all gravel has been removed from <br />the property. <br />b) Topsoil and overburden will be removed and stockpiled using dozers and front- <br />end loaders. Gravel wilt be mined using front-end loaders andfor excavators. <br />Grading and topsoil replacement will be done with dozers and front-end loaders <br />and graders after gravel extraction <br />c) No water diversions or impoundments are anticipated for this operation <br />d) The size of the area to be worked at any one time will be 10 to l5 acres. <br />e) Mining will commerme in the spring of 200,f~- It is estimated that each bench will <br />take 3 to 5 years to rxrmplete and drat there will be pans of two benches active <br />once the initial bench is near completion This wits allow processing and <br />stockpile space on the upper beceh as excavation of the next bench is beginning. <br />Grading and topsoiling will be done on the upper bench after all gravel has been <br />removed to the north and west limits of that bench as defined by ericoumeriag the <br />underlying shale slope. We estimated the maxanum area in disriabance at any <br />one time would be about 7 5 acres. Mining is expected to be completed in tbe fall <br />of 2050. <br />f) The deposit to be mined consists of eraled stream terraces that form ridges <br />radiation south ~d east from a larger ridge to the northwest. 'The gravel is <br />underlain by shale. Soil overburden ranges from 0 to greater than 6tl inches of <br />fine-loamy material. The thickness of the gravel deposit ranges from a few feet to <br />greater than 50 feet. <br />g) The primary commodity to be mined is sand and gravel to be used as construction <br />aggregate. <br />h} Larger rocks abe boulders fiom the site may be used as decorative rock for <br />landscaping around homes and businesses. <br />
