within an earthen berm that will have a capacity of at least 110%of the volume of the tanks <br /> to be kept onsite. No permanent structures will be built within the permit area as part of this <br /> operation. Water will be used to control dust on site. Water for this operation will be <br /> purchased from an offsite source in Colorado City and trucked to the site It is estimated that <br /> the operation will consume up to 10,000 gallons of water per day for dust suppression. <br /> Portable plants will be used onsite for rock crushing. Spray bars will be used in the crushing <br /> and screening plant to minimize dust. <br /> Aggregate processing equipment is portable. The processing equipment may move and <br /> follow active mining throughout the site. Portable mining equipment such as loaders, dozers, <br /> trucks, and excavators will be serviced onsite as needed. Upon reclamation,all portable <br /> equipment will be removed from the site. <br /> On-site roads are temporary and will change as mining progresses to the east. Support <br /> equipment will come to the site on an as-needed basis.Night mining activity may occur <br /> in the operation and portable lighting may be used within the pit from time to time. Portable <br /> toilets will be used for employees. <br /> Stormwater drainage on the disturbed areas will be directed by berms that border all <br /> disturbed areas of the site. The operation will create a depressed area. No stormwater or <br /> process water will leave the site and will be directed toward the center of the disturbed area <br /> where it will infiltrate within 72 hours. Except for the highwall,which will not exceed 200 <br /> feet in length and 20 feet in height, slopes will be maintained at 3H:1 V or shallower. <br /> 9. Topsoil and Overburden Handling <br /> Topsoil will be salvaged from the disturbed areas and placed in temporary perimeter berms <br /> surrounding the disturbed area. Piles are shown at the perimeter of the permit boundary on <br /> the Mining Map. These stockpiles will be seeded with the reclamation seed mix listed <br /> below. Topsoil is expected to be approximately 3-4 inches and overburden is expected to be <br /> approximately 18-30 inches. The topsoil and overburden berms will be used for reclamation <br /> to construct 3H:1V slopes or shallower. The deposit is approximately 20 feet in depth. The <br /> haul road will be approximately 30 feet wide and will be constructed as with any gravel <br /> Page 9 of 24 <br />
