Table D-2 Moonscape Pit Mining Sequence <br /> per <br />Productio Length of time to <br />Year year to phase Comments complete months <br /> 9 1 Site Preparation, Topsoil stripping, build stockpile along northern 1 <br />2009 permit boundary. <br />2009- 30 <br />000 2 Mine in Mining Area 1, stockpile topsoil. Seed the stockpile. Place 61.8 <br />2014 , overburden on the pit floor. Seed the topsoil stockpile. <br />2014- 30 <br />000 3 Mine in Mining Area 2, place topsoil on the sideslopes and pit floor 58.8 <br />2019 , of Mining Area 1. Seed and mulch topsoiled area. <br />2019- <br /> <br />30,000 <br /> <br />4 Mine in Mining Area 3, Place topsoil on the sideslopes and pit floor <br />26.2 <br />2022 of Mining Area 2. Seed and mulch topsoiled area. <br /> Remove scale and mobile equipment. Place stockpiled topsoil on the <br />2022 - 5 pit floor and sideslopes of Mining Area 3 and the pit floor of the 0.5 <br /> existing pit area. Seed and mulch topsoiled area. <br /> Total 148.3 <br />The mining schedule is planned to minimize disturbance by reclaiming areas as additional <br />mining is undertaken. This table is based on a reasonable projection of average production rates. <br />The table shows that mining and reclamation will occur approximately 12 years and the total <br />gravel mined will be approximately 366,900 tons. This is based on the average thickness of the <br />loose gravel and the conglomerate gravel being 14.5 feet, and the area of land being mined. <br />3. Mine Facilities and Operation <br />The crushing and screening will take place within the Product Stockpile and Processing Area. <br />Fuel will be brought to the site by a mobile fueling truck. No new permanent structures will be <br />built within the permit area, since all necessary structures are already located on site. Water will <br />be used to control dust on the haul roads. Water for this operation will be trucked to the site from <br />an offsite source. The source of water is Seep Creek. It is estimated that the operation will <br />consume 4,000 gallons per day for dust suppression. <br />Maintenance vehicles will visit the site regularly to provide oil, grease, and perform other minor <br />maintenance on vehicles and equipment. Any major repair work required will be performed off <br />site. <br />Moonscape Pit, July 2009 D-3
