Mud Creek Pit -Reclamation Permit Application -112 (C) Exhibits Page 51 of 67
<br />TRAFFIC COUNTS AND SCHEDULES
<br />See CDOT access application and permit.
<br />DUST CONTROL DURING HAULS
<br />Dust control practices to be used in the pit, including the access road, will be based on pit traffic, and will include
<br />traffic control, water spraying (see Exhibit G), and use of dust control agents such as magnesium chloride brine
<br />(magwater) or ligneous sulfide, as needed. When hauling material less than %4-inch, haul trucks will be controlled to
<br />prevent dust, including tarping (chemically or physically) or wetting of material in accordance with state and local
<br />requirements. If necessary, hauling will be curtailed during extreme high wind conditions.
<br />BLASTING AND NOISE CONTROL
<br />Actions will reduce the impact of noise caused by the mine and associated activities.
<br />BLASTING There will be no blasting done on site for the Mud Creek Pit.
<br />NOISE POTENTIAL
<br />Due to the location of the site, sloping away from US-160 and in a wide valley setting, little 'rf any problem
<br />with noise is expected, as discussed above, and noise reduction is taken into account in the overall design and
<br />selection of stockpile and plant locations, direction of working, and other noise control measures integrated into
<br />the operation.
<br />Typical sources of noise associated with sand and gravel extraction include operation of mobile and
<br />stationary equipment (engine, conveyor and like noises), back-up alarms, movements of vehicles inside and to
<br />and from the site (brakes, acceleration, etc.), and noises associated with heavy machinery and construction.
<br />During periods when traffic is not present on US-160, other sounds carry well, but traffic is steady on this
<br />highway.
<br />The nearest dwellings are the Neva family house to the east, and the Hogan (a trading post) and several
<br />associated houses to the south. For the most part, the south buffer (facing US-160) ensures that operations are
<br />separated from these potential receptors, and noise levels will remain under the state-mandated 55 dBA at those
<br />receptors, and will comply with County Land Use Code requirements.
<br />NOISE CONTROL
<br />The proposed layout of the pit takes noise control and reduction into account. Most noise
<br />from excavation, loading, screening, washing, crushing, and other operations at the quarry
<br />will be done in areas below grade, so that the walls of the pit will reflect sound up and away
<br />from adjacent properties and roads and other areas where people are often present. Only
<br />stripping will be conducted above grade. This will be partially buffered by use of stockpile
<br />berms as they are built. This will allow the terrain features on site and off-site to act as
<br />sound barriers.
<br />Operating procedures for all McStone Aggregates pits are designed and implemented to
<br />reduce the impact of noise in the area and for neighbors. There will be no blasting.
<br />Operating hours, maintenance of noise controls on equipment, and training of personnel will
<br />be conducted in accordance with local requirements. Because of terrain, the two neighbors
<br />to the south may be initially modestly affected by operations, until the first portion of the pit is
<br />open, berms are built, and most activities move to below ground level. However, a large
<br />buffer has been established to reduce this impact, and the two nearest houses (not owned
<br />by the pit landowner) are more than 500 feet from any operations. Operations will move
<br />constantly away from these two houses, and wooded areas, as well as the berms, will buffer
<br />these locations. Other neighbors are not located where general pit operations will be heard,
<br />but may be affected by traffic noises.
