land is zoned as AFT (agriculture, forestry, transitional), a special use permit is needed to conduct <br />gravel mining on this site <br />The average total aggregate annual production rate is given as 450,000 tons per year. Occasional big <br />jobs such as a large Interstate repaving project, etc., may exceed these averages but other periods <br />will see less activity, so the average is appropriate for estimating long term truck traffic. Using this <br />amount, the site will average trucking 37,500 tons/month. Using 25 days/month activity, this is 1500 <br />tons per day. Using 10 hrs/day, this is 150 tons/hr. Using 24 ton trucks, this is 6.25 trucks per hour. <br />Maximum truck traffic is expected to be 7-8 trucks per hour. All trucks will be covered and water <br />and/or magnesium chloride will be applied to the site access road as needed to keep dust down. <br />United is working with the State Highway Department in addressing all concerns for access to High- <br />way 50 and the town of Fruita. It is estimated that 90% of the trucks will go east to Fruita and will <br />remain on the frontage road to the western edge of Grand Junction, where the trucks will proceed <br />south on the River Road to United's main facility located a short distance south of the Interstate <br />frontage road. The vast majority of the trucks will not enter I-70 at Fruita. Some traffic (approx. <br />10%) will proceed west of the Piton Highway 50. <br />As described in the mining plan, the hydrologic system will detain all runoff so that no sediment will <br />leave the site and cloud any downstream waters. The 15 Road Pit will be reclaimed to part wildlife <br />habitat and part industrial/commercial use. United will work closely with Division of Wildlife, the <br />County, the landowners and the DMG to ensure that the reclamation plan is the best possible for <br />achieving the post-mining land use. Portable sanitation facilities will be provided to all workers at <br />the minesite. The waste will be taken off site for treatment in an approved facility. There will be no <br />leach fields or other means of sewage disposal. There will be no new demands on Mesa County ser- <br />vices from the additional extraction areas. <br />A gas line and power line that runs through [he property will be avoided and have played a large part <br />in determining the configwation of the lakes. <br />15 Road Pit 10102 23 <br />
