<br /> <br />GENERAL <br />MINING PLAN <br /> <br />The sand and gravel mining operation proposed in this <br />application will be a major disturbance. It is an exp <br />the existing Barnhart Pit limited impact (110) permit <br />(112) permit. <br />~rmit <br />:ion of <br />~ a regular <br />The aggregates to be mined vary in thickness from 23 t 27 feet <br />averaging 25 feet and will be removed down to the unde lying <br />shale, some 26 to 30 feet below surface elevation. Th deposit <br />contains approximately 2.06 million tons of aggregate. (Pit run) <br />Maximum anticipated mining rate will be 350,000 tons p <br />resulting in a pit life of 5.71 years. The exhibits a <br />timetables are predicated upon this extraction rate. <br />rate may vary from this due to market conditions and c <br />demand for the products. The sequence and relative ti <br />presented in the plan will be followed. <br />TOPSOIL <br />Topsoil within the affected area varies in thickness f <br />/ inches averaging approximately 26 inches. All availab <br />will be removed from areas prior to any other disturba <br />material will be stored in locations as shown on Map D <br />possible, be placed in concurrent reclamation areas wi <br />interim storage. Topsoil handling will be done with f <br />loader and/or scraper. <br />Topsoil in storage will be protected from erosion by d <br />berming around the sides of the piles. <br />No material other than the immediate topsoil exists o <br />bearing aggregates. Therfore, no other stockpiles of <br />material will be required. <br />MINING <br />The high ground water level and proximity to the Arkan: <br />will yield a wet pit operation as demonstrated by prior <br />ations. Primary extraction will be done with a 1-1/2 ~ <br />Northwest dragline. A minor amount of the aggregate m. <br />removed with front-end loaders.
