Exhibit "C" 6.3.3 The Mining Plan for the Wet Canyon Gravel Pit is as follows, (please also see map). (a) Specify the estimated dates that mining will commence and end: Present plans aze for mining to start in the 3rd quarter of 2003 after pernilt approval. The 9.90 acre deposit is anticipated to have a life of 15 to 20 years depending upon population growth and the overall demand in this azea. This pit will be used for road base for the local roads that will be needed for the new homes and methane well development in the general area. Also construction aggregates will be sold in the area for private drive-ways, as well as structural fill and other construction activities. (b) The depth of plant growth medium to be salvaged for reclamation will vary with soil types. However it appears that the majority of the topsoil is a Gulnaze soil and the thickness will range from 10 to 16 inches. Therefore the operator will remove this layer of soil and save it for reclamation. Typically the surface is stony sandy loam 3 inches thick and the subsoil is gravelly clay loam and sandy clay loam 12 inches thick Although it is a sandy- loam topsoil i[ is an adequate growth medium. Established topsoil stockpiles will be saved on site and moved only when needed to prepaze the site for seeding. Topsoil stockpiles will be seeded with 7#/ PLS per acre of We"stern Wheatgrass to reduce the chance of erosion. Plant growth stockpiles will be • located separate from other stockpiles (which will be product) out of the way of mine traffic and drainage-ways. The location of plant growth medium stockpiles will be shown on DMG Exhibit "E" ma P• (c)The overburden depth vanes from 10" to 16". Most of this material will used for growth medium and used on the mine site to prepare for seeding. There is no waste rock in this deposit all of the rocks will be sold or used in reclamation therefore no waste rock or overburden piles will be left after reclamation. (d) Present indications are that the deposit that will be mined is 10 to I S feet deep. This is the best estimate at this time as mining goes forwazd it might be more. or less. (e) The major components of the mining operation are limited. Access to the pit will be by an access road constructed on the southeast side of the pit connected to an existing driveway road to the applicanUoperators home which the owner wants left for use upon completion. There will be no office, shop/maintenance facility. The only plant andlor processing facilities could be a portable crusher, and screening and gravel processing equipment production is expected to be less than 70,000 tons per yeaz. Since this is a dry open pit operation there will be no underground openings such as adits or ventilation facilities. The DMG Exhibit "E" map will shows the pertinent details. (f) The permit area is 9.90 acres. There will be no mine benches, impoundments, or • water rock disposal azea. ~s ,.
