• Exhibit Page 46 • <br />BLASTING AND NOISE CONTROL <br />Actions will be taken to reduce the impact of blasting and noise caused by the mine and <br />associated activities. <br />BLASTING <br />There will be no blasting done on site for the Line Camp Pit. <br />NOISE POTENTIAL <br />Due to the location of the site, located in a narrow valley between two 700 foot valley <br />walls, some problem with noise is expected, as discussed above, and noise reduction is <br />taken into account in the overall design and selection of stockpile and plant locations, <br />direction of working, and other noise control measures integrated into the operation. <br />Typical sources of noise associated with sand and gravel extraction include operation of <br />mobile and stationary equipment (engine, conveyor and like noises), back-up alarms, <br />movements of vehicles inside and to and from the site (brakes, acceleration, etc.), and <br />noises associated with heavy machinery and construction. During periods when traffic is <br />not present on Highway 145, other sounds carry well, and sound reflects off the valley walls. <br />Other than the Line Camp itself, the nearest dwellings are the Robinson family <br />house/camp approximately 1100 feet south and the Arin house approximately 850 feet <br />south and across the river from the south edge of the pit. <br />NOISE CONTROL <br />The proposed layout of the pit takes noise control and reduction into account. Most <br />noise from excavation, loading, screening, washing, crushing, and other operations at the <br />quarry will be done in areas below grade, so that the walls of the pit will reflect sound up <br />and away from adjacent properties and roads and other areas where people are often <br />present. Only stripping will be conducted above grade, except during the first half of the <br />first year's operations when screening, washing, and crushing will be done at two feet below <br />the original grade level. This will be partially buffered by use of stockpiles for berms. <br />Future stripping will be done behind additional berms on the permit boundaries. This will <br />allow the terrain features on site and off-site to act as sound barriers. <br />Operating procedures for all Four States Aggregates sand pits are designed and <br />implemented to reduce the impact of noise in the area and for neighbors. There will be no <br />blasting. Operating hours, maintenance of noise controls on equipment, and training of <br />personnel will be conducted in accordance with local requirements. Because of terrain, the <br />two neighbors to the south may be initially modestly affected by operations, until the first <br />portion of the pit is open, berms are built, and most activities move to below ground level. <br />However, a large buffer has been established to reduce this impact, and the two nearest <br />houses (not owned by the pit landowner) are more than 500 feet from any operations. <br />Operations will move constantly away from these two houses, and wooded areas, as well as <br />the berms, will buffer these locations. Other neighbors are not located where general pit <br />operations will be heard, but may be affected by traffic noises. <br />All complaints received by Four States Aggregates will be recorded and investigated <br />immediately. New methods of noise control will be regularly considered and adopted when <br />feasible. <br />Four States Aggregates, LLC 30 DEC 2000 <br />Application for Permit: Line Camp Pit FSA-LCP-D1-001 <br />
