EXHIBIT D—Mining Plan <br /> a) Mining will utilize the following operations: <br /> i. Remove and stockpile and existing top soil <br /> ii. Utilize dozer to push up gravel <br /> iii. Utilize a frontend loader to load material onto trucks. <br /> b) The site will be mined to approximately 15-20 feet deep. If supply is abundant, mining <br /> could go deeper. Mining will be done on an approximate 3:1 slope down to the bottom of <br /> the pit area. Topsoil is approximately 5" in depth. The topsoil will be stripped, stockpiled, <br /> and utilized when the pit is reclaimed. <br /> c) There are no anticipated water diversions or impoundments. There is no surface water at <br /> the site. When rainfall occurs, the pit area may be unworkable for a few days. Since the <br /> use of the pit is intermittent, we will be able to work around those occurrences. <br /> d) Our intent is to work approximately one-half of the new area at a time. <br /> e) Sand and gravel will be mined over the entire pit area. Topsoil will be stockpiled to the <br /> north side of the pit prior to commencement of mining. The area north of the creek in the <br /> expanded area will be mined first. Mining will proceed from the creek northward. The <br /> southern portion of the expanded area will be the last portion mined. Excavation will <br /> continue as gravel is needed for local road operations and as the supply remains available. <br /> It is anticipated that mining will be from 15-20 feet deep, but if supply is abundant, mining <br /> could go deeper. Some stockpiling may be done at the site, but most of the gravel will be <br /> utilized as it is mined. Any stockpiling that does occur will parallel the creek bed so as not to <br /> restrict flow. No processing of material is anticipated in the pit. The pit will continue to <br /> operate annually. The supply is undetermined, but is expected to last indefinitely because <br /> of the limited use of the pit. Mining will begin as soon as all the proper permits are <br /> obtained. <br /> i. Since the pit will be used on an intermittent basis, it is difficult to estimate the time <br /> it will take to mine the new area. We are estimating it will take ten years to mine <br /> the pit. <br /> ii. Area 3 will be approximately 4 acres and is located on the northern portion of the <br /> pit. Area 4 will be 5.9 acres and is located south of area number 3. <br /> iii. Newly added areas 5 and 6 will be the expansion Area 5 is approximately 2.0 acres <br /> and is located the northern portion of the pit. Area 6 will be 8.2 acres and is located <br /> south of area number 5. <br />
