will be extracted by Excavator then transported and fed(dumped) into the screener or crusher <br /> by Front End Loader.Screeners will separate the product by conveyor into processed material <br /> piles which are transported by Front End Loader to waiting trucks and/or stockpiles located on <br /> site.There are no planned underground openings or ventilation facilities on site. <br /> (b) Earthmoving shall commence with the removal and stockpile of existing topsoil. <br /> The method used for removing the topsoil shall include, but not be limited to,the use of <br /> carryalls, dozers,front end loaders,and trucks to scrape, push and haul the topsoil to the <br /> stockpile area located at the south end of the affected mining area.The estimated depth of <br /> topsoil in the affected mining area is 4"-8".The topsoil soil shall be separated and placed in <br /> a stockpile independent of mining activities and stabilized with vegetative cover if necessary. <br /> (c) The boundaries established for the affected mining area shall be enforced in an effort to <br /> minimize any detrimental disturbances to the existing hydrologic balance with-in the permitted <br /> area.Storm water shall be captured on-site with the use of a storm water rock filter established <br /> on the Southwest center boundary of the affected mining area.The planned filter includes, but <br /> not limited to,an approximately 100'-0"long x 3'-0"wide cleaned and screened 1%"gravel <br /> berm approximately 18"to 24" high.The berm will be located approximately 3 to 6'inside the <br /> west permit boundary line and is intended to mitigate and prevent storm run-off by allowing <br /> storm water to be immobilized then filter and evaporate naturally. If ground water is <br /> encountered during mining operations every effort will be made to stop flow and mitigate any <br /> future seep. <br /> (d) The pit excavation area,stockpiles,drive area dimensions and other disturbances to the land <br /> surface shall vary,however,will incorporate,and be limited to,approximately 19 acres M/L as <br /> permitted.See Exhibit D"Mining Plan Map"for excavation,extraction,stockpile and drive <br /> descriptions. <br /> (e) The approximate timetable for mining operations define an estimated date of commencement <br /> for excavation, processing,and sales of materials on,or around, March 1,2015.With an <br /> estimated end date on,or before March 1,2022 The site will be prepared and planted as one <br /> contiguous area and not in phases. <br /> (f) The estimated thickness of the deposit to be mined is 40 feet.The anticipated direction of <br /> material extraction shall be South to Southwest as shown on the Mining Plan Map.While <br /> excavating the deposit a high-wall shall be created.The wall will be approximately 30'-0"to <br /> 40"-0" high,based on the anticipated product thickness,at 1:1 slope and approximately 1100 ft. <br /> in length along the North, Northwest Boundary lines at any given time during mining <br /> operations.Technical Review may be requested as necessary. Riverside Aggregates, LLC <br /> plans to mine 40',or, potentially deeper if necessary to extract material. Deeper cuts <br /> shall be backfilled as required to permit depths with-in 60 days of excavation. <br /> Deposits will be processed:excavated,screened,and crushed on-site. Material <br /> screener(s)and crusher(s)are located on the Southwest area of the site. Pit run material will be <br /> extracted by Excavator then transported and fed(dumped) into the crusher and screener by <br /> Front End Loader.Screeners will separate the product by conveyor into processed material piles <br /> which are transported by Front End Loader to waiting trucks and/or stockpiles located on site. <br /> The operator will use no chemicals in processing the deposits.No refuse or acid forming or <br /> toxins should be mined.Any additional overburden shall be separated and placed in stockpiles <br /> on the east end of the affected mining area.The estimated thickness of overburden is 12"-24". <br /> The nature of stratum immediately beneath the material mined appears to be Rocky Ford Clay <br /> Loam.See Exhibit D"Mining Plan Map". <br /> (g) The primary commodities extracted include gravel,road base,and crusher fine material. <br /> Primary commodities are intended for use on county road projects,commercial and/or <br /> residential construction projects and state hi-way construction projects.Secondary <br /> commodities, if encountered,may include sand and large rock and may have diverse uses <br /> Friederichs Pit 112-Riverside Aggregates,LLC. <br /> October 1,2014 Page 3 <br />
