EXHIBIT D -Mining Plan (6.4.4) <br />(a) It is proposed that the method of mining will remain consistent throughout <br />Phases A, B,C, and E. This entails the removal of topsoil (where <br />applicable) and overburden utilizing, bulldozer and scrapers. Mining <br />operations will involve surface extraction with front-end loaders and/or <br />excavators. Phase C will be prepared utilizing trenched dewatering <br />techniques and mined with an excavator andlor front-end loader. <br />(b) Topsoil (where applicable) and overburden will be sequentially removed <br />from each phase with scrapers, dozer and and/or motor-grader. Such <br />material will be placed in perimeter berms as shown on Exhibit C. <br />(c) No water diversions are anticipated in Phases A, B, C, or E. Dewatering of <br />Phase D will be necessary to excavate the gravel. This will be <br />accomplished when appropriate water rights and state approvals are <br />granted. Impoundment and detention of stormwater are shown on Exhibit <br />C. <br />(d) Each phase as shown on Exhibit C varies in acreage. 1t is the intent of the <br />operator to mine an area within each phase not to exceed ten acres at any <br />given time. <br />(e) It is anticipated that this pit will be mined on a seasonal basis. As <br />mentioned above, the operator intends to mine in ten-acre increments. <br />Dependent upon market demand and production rates, it is expected that <br />each ten-acre area will be worked for a period of 12 to 24 months, <br />including off-season shut downs. <br />(f) The following information is CONFIDENTIAL. <br />(i) Phases A, B and C consist of terrace deposits with varying depths of <br />topsoil and overburden. The average depth to gravel is assumed to be 4 <br />feet {0 - .5' topsoil, 3.5 - 4' overburden). The average depth of grave{ is <br />predicted to be 11'. Phase D lies above the stream channel of the Florida <br />River and is alluvial in nature. This phase appears to have 2 -3' of <br />overburden and 10 - 15' of sand and gravel. Phase E lies atop the ridge <br />west of the Florida River valley. There is no perceptible topsoil in this area. <br />Overburden is expected to range from 3 -10'. The depth of gravel is <br />assumed to be 15 - 20'. <br />(ii) With the exception of Phase D, the strata underlying the gravel deposit <br />are either shale or mudstone. It is not known with certainty what underlies <br />the deposit in Phase D. <br />
