~E~rr~,~ <br />I~ <br />MINING PLAN <br />AFit 1 ~ wu6 <br />EXHIBIT D <br /> <br /> <br />1. General Plan- Mining <br />Division °f Minerals and Ge°legy <br />Up to the permit new permit in 2006, the Bellgazdt Pit permit area consisted of approximately 19.5 <br />acres. The gravel zone is approximately 20-30 feet thick in a dry terrace deposit and is overlain by <br />soil and overburden of 2-10 feet. The average thickness of soiUoverburden is 1-3 feet. The gravel <br />zone to be mined in the 2002 Amendment and 2006 new permit azeas (Strip 1, 2 3, and 4) is <br />approximately 20-30 feet thick. Overburden increases as the terrain rises to the north. For the <br />relatively small size of the pit, all gravel and overburden zones can be assumed to be dipping at <br />approximately 5% to the southwest. The azea is mined by first excavating soiUoverburden with <br />dozers or front end loaders and stockpiling the material in separate stockpiles located south of the <br />pit, as shown on Map C-2. The raw gavel material is then loaded with a loader into a portable <br />crusher/screen plant and various sizes of product aze made and placed in sepazate stockpiles. The <br />portable plant usually operates for only one 4 - 6 week interval per yeaz. Mining proceeds from the <br />north end of the gravel deposit to the south, where the terrain is also dipping at a relatively steep <br />angle. The mining of the deposit will occur to the limits shown on Map C-2 and will be mined to a <br />slope no steeper than 2H:1 V. This is the same as the final slope of the land so that no backfilling <br />except topsoiling will occur after mining. No blasting will be performed at any time for this <br />operation. <br />Since there is a lack of topsoil in the main pinon juniper community which will be disturbed in <br />Strips 1 through 4, overburden will be used to reclaim the flat bench portion of the permit azea. The <br />topsoil will be used to cover the disturbed slope azeas. <br />The 2006 new permit was made to allow mining of the adjacent azea to the west of the previous <br />permit. This is done by adding approximately 16.52 acres, which results in a total permit azea of <br />36.02 acres. The disturbed area for the permit is 26.44 acres. The maximum total tonnage mined <br />and sold from the site in any one calendaz yeaz is 65,000 tons, which has not changed since the <br />initial permit and will not change for the new pernut in 2006. This tonnage includes all products, <br />Bellgazdt Pit 1/06 <br />
