06-26-2000 07:SSAM FROM J. E. STOVER 8 R950CIRTES TO 101089919702475104 P.05 begin and can be simultan~us after approximately 235,000 tons of • 1 aze produced. This inidai production period would last approximately 4 years. As the mining advances in an easterly direction, cover material will be trucked directly from the azea stripped to the reclaimed area, graded to final contours and then re-seeded. Approximately, 6.2 acres of the Phase II pit will be stripped of topsoil or cover material to create material to finish covering the Phase I disturbance. Refer to Exhibit F, Reclamation plan for reclamation sequence. The material removed from the pit will be hauled to a portable crushing and screening unit by the liontend-loader as it is removed from the pit. This cntshing and screening plant will size the gravel material and duect it to stockpiles for reloading and hauling off-site. The screening and crushing plant will be powered by a portable dieseUelectric generating set with a 350 gallon fltel tank, positioned neazby. The operator has no plans for an olIIce, but will have a truck fouler converted to a material shed located nearby the crusher and materal removal operation. A portable sanitation facility ("ports-pottP~ will be located near the supply trailer. A 1500 gallon fuel storage tank for fueling equipment and the generator fuel storage tank will be located in appropriate bermed and plastic lined containments. All ofthe above equipment is portable and will be relocated (always kept on disturbed soar) as the mining face advances to reduce loader cycle times and facilitate reclamation Any hazardous materials/petroleum products stored in the storage trailer will be stored in a containment cabinet designed for the purposed of providing primazy containment of spills. A semi portable truck scale will be installed neaz the property entrance along the haulage road neaz its intersection with the Redvale Road. Tlris scale will be mounted on three concrete piers measuring I S"wide x 12'7tigh x 8'long. Excavation of the gravel pit will create neazly vertical advancing and side slopes. The side slopes will be reduced to a 4h:ly slope before topsoil is applied and graded to depth. The advancing face of the pit will also be reduced to a 4h:ly slope as the pit is exhausted. Care will be taken to keep all activities and disturbance within the projected pit disturbance boundaries. A large puriivn of the projected disturbance are within azcas where the vegetation can be chazacteri~ed as noxious weeds and cheat grass. Noxious weeds on the permit area will be controlled per the Weed Control plan included in Exhibit J -Vegetation. A small portion of the phase li. area is interspersed with wetland species. The applicant does not believe this small azea is a jurisdictional wetland due to the influence of irriEation water. The area in question dots not fall within the next 5 years of mining, is not transected by access roads and will be tested to determine if it is a jurisdiction wetland prior to disturbance. However, mining may proceed in the phase II area before this determination is made as long as there is no disturbance to the wetland azea. The gravel deposit lies directly on a sandstone shelf. This sandstone has been detemlined to bean aquifer. Drilling indicates ground water may be present in the lower 10 feet of the gravel deposit. Mitring experience will dictate to what depth the gravel deposit maybe removed without disturbing this ground water. If ground water is encountered, pit floor projections will be revised to maiatain a m;.,;mum of 2 feet of undisturbed material about the ground water. The access road directs all truck traffic to all three phases of the gravel pit accesses the wunty maintained Redvale Road approximately SSO' east of the nearest dwelling. The planning of this road minimizes the effects of dust and noise generated by the operation on the rural lifestyle of the local community. D-2
