Exhibit Page 42 <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 Hay Camp Pit (Combined). <br />NOISE POTENTIAL <br />Due to the location of the site, located on a high mesa, some problem with noise is <br />expected, as discussed above, and noise reduction is taken into account in the overall <br />design and selection of stockpile and plant locations, direction of working, and other noise <br />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 />The nearest dwellings are various residences and businesses approximately 1600 feet <br />north, in the Dolores River Valley, and located north of the river and Highway 145. It is <br />more than one mile to any residences to the south, where farms and rural dwellings are <br />located along Highway 184 (Dolores-Mancos Highway). There are presently no residences <br />on either the Wallace or LMN Properties land, and none along County Road S to Highway <br />184. <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. Future <br />stripping will be done behind additional berms on the permit boundaries. This will allow the <br />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. <br />All complaints received by Four States Aggregates will be recorded and investigated <br />immediately. New methods of noise control wiH be regularly considered and adopted when <br />feasible. <br />
