Blue Pit 112 Permit Amendment <br />disrupt the functionality of the ditch since this ditch supplies water users downstream. This will be <br />accomplished by mining as close as possible to the ditch from Mining Area i and then mining as <br />close as possible from Mining Area 2. <br />Schedule of Operations <br />Mining and processing will continue to operate 12 months per year. The hours of operation will be <br />Too a.m. to 5:00 p.m with administrative and maintenance functions occurring one hour prior and <br />two hours after the hours of operation, Monday through Saturday. <br />Garfield County Impacts and Environmental Impacts <br />The aggregate production is estimated to be average 450,000 tons annually, although this is only <br />approximate since past forecasts of economic conditions have been erratic. Impacts to Garfield <br />County include: <br />a) Truck traffic: The site will continue to use the same haul route to Highway 82, which is a <br />private road and is shown on Map C -2A and C -213. The daily or hourly haul traffic is not <br />increasing with the expansion of the reserves. There is an additional haul route when servicing <br />the area to the north of the pit which only produces a very small amount of tonnage per year. <br />This haul route uses CR 103 and CR 104 to access Crystal Creek Road and is shown on Map C- <br />aA and C -aB. <br />The haul traffic from the current operation exits the site from a private road and intersects <br />Highway 82 as shown on Map C -i. The haul traffic for the expanded operation will access the <br />site in the same fashion as it does currently. The existing access to Highway 82 has an access <br />permit from CDOT. Even though the Blue Pit is expanding, the annual production is going to <br />stay the same which means the truck traffic will stay the same. A traffic study was conducted <br />for CDOT to keep the existing access permit in the year eon and CDOT determined that the <br />existing permit is valid, CDOT will require improvements to Highway 82 access at a later date, <br />which will primarily involve an extension of the acceleration /deceleration road lanes to the pit <br />access road, which is located outside of the DRMS permit area. There is a small amount of truck <br />traffic that accesses the area north of the Blue Pit through CR 103 and CR 104. This access route <br />is only used for product sales north of the pit on Crystal Creek Road and is a very small amount <br />of the annual production. <br />b) Noise: Western Slope Aggregate has operated the site since 1991 and has not had a noise <br />violation. WSA will continue to operate the site below the state noise limits. A full noise study <br />was conducted and is part of the County Special Use process. <br />c) Dust: The processing equipment, along with the mining operation, has air emission permits in <br />place and will not be changed as part of this expansion. These air permits need to be revised <br />every 5 years and will be kept up to date with items relative to dust emissions. <br />Blue Pit May 2014 D -8 <br />
