total gravel volume to be mined is 190,000 cubic yazds. This is equivalent to 285,000 tons. These <br />calculations are approximate since the exact extent of the gravel deposit in the field is unknown. The <br />maximum annual mined tonnage rate for the pit is 70,000 tons, therefore, the mine azea will last ap- <br />proximately 4.1 yeazs, assuming the maximum rate is sold each yeaz. The mining of the azea will <br />leave 2.OH:1.OV sideslopes on all final outside slopes down to the mining depth. In fact, during the <br />mining process, the dozer will mine the deposit at a 2H:1 V slope, therefore, the worst case bond cal- <br />culations for reclamation will simply involve backfilling to 3H;1 V, replacing topsoil, then seeding. <br />No mining will be conducted at night. Mining will only be allowed from 6 am to 7 pm, Monday <br />through Saturday. No processing of any kind will occur on the North Fork Pit site. All material will <br />be mined with a front end loader and trucks will take the raw material over a flat caz bridge to the <br />processing area of the River Bottom Pit. The majority of the material will be mined, crushed and <br />sold in the spring, summer and fall months. There will be no fence azound the operation, since it is <br />well inside private property and there aze no facilities on site. No problems aze expected with van- <br />daIism. Access to the site is from 4005 Lane, which is a County Road. The mine sign will be posted <br />at the end of this road, adjacent to the Pit entrance. <br />It is extremely unlikely that any toxic or acid-producing materials will be encountered during the <br />mining operation since the total depth of excavation (20') is shallow and tests down to this depth <br />show that the material is alluvial in nature. However, in the event that such materials are encoun- <br />tered, they will be covered with topsoil from the stockpiles to the same depths outlined in the recla- <br />mation plan and no more mining will occur in this area. <br />United commits to cleazly mazking the permit boundary at all corners <br />North Fork Pit March 04 l9 <br />
