periods of inactivity based on production activity, stockpile Inventory and demand. Boundary markers will be located at each corner and at Intervals. Boundary markers will be clearly marked on North, South and West boundaries to ensure offsite areas will not be disturbed by mining operations. The product extracted will be processed on -site and may include gravel, sand, road base, and crusher fine materials. a. The estimated date of commencement shall be on, or around September 1, 2014. The estimated end date shall be on, or before September 1, 2021. b. The initial mining operation shall commence with the removal and stockpile of existing topsoil. The method used for removing the topsoil shall include, but not be limited to, the use of carryalls, dozers, front end loaders, and trucks to scrape, push and haul the topsoil to the stockpile area located at the south end of the affected mining area. The estimated depth of topsoil in the affected mining area is 6" -14 ". The topsoil soil shall be separated and placed in a stockpile independent of mining activities and stabilized with a grass mix vegetative cover as necessary. c. The topsoil and any additional overburden shall be separated and placed in stockpiles on the East end of the affected mining area. The estimated thickness of overburden is 12" - 24". e. The estimated thickness of the deposit to be mined is plus or minus 40 feet. The anticipated direction of material extraction shall be South to Southwest as shown on the Mining Plan Map. While excavating the deposit a high -wall shall be created. The wall will be approximately 30'-0" to 40"-0" high, based on the anticipated product thickness, at 1:1 slope and approximately 1100 ft. in length along the North, Northwest Boundary lines at any given time during mining operations. See Exhibit C "Mining Man Map° for location details e. The main mining entrance is located on existing County Road LL The access road from the main entrance to the Friederichs Pit 112 is an existing, well maintained, dirt and gravel road. The affect mining area includes portable pit office and toilet facilities. The mining site entrance/exit is located on the Southeast corner of the site. Material screener(s) or crusher(s) are located on the Southern area of the site. Pit run material will be extracted by Excavator then transported and fed (dumped) into the screener or crusher by Front End Loader. Screeners will separate the product by conveyor into processed material piles which are transported by Front End Loader to waiting trucks and /or stockpiles located on site. There are no planned underground openings or ventilation facilities on site. See Exhibit C "Mininx Plan Map" for location details. f. The pit excavation area, stockpiles, drive area dimensions and other disturbances to the land surface shall vary, however, will incorporate, and be limited to, approximately 19 acres as permitted. See Exhibit C "'Mining Plan Map" for excavation exaacdon, stockpile and drive descriptions. g. The existing approximately 40'x SSO'access road does not require modification or improvement. No new roads or road improvement are required or included in this application. h. Water used for the operation of the Friederichs Pit 112 will be minimal and sporadic. Any water used in the operation of the pit will originate off-site per the operators current source(s) of non- potable water, be loaded into tanker(s) and trucked onto the site to be used as needed. I. Storm water shall be captured on -site with the use of a storm water rock filter established on the Southwest center boundary of the affected mining area. The planned filter includes, but is not limited to, an approximately 100'-0" long x 3'-0" wide cleaned and screened 1 W gravel berm approximately Ur to 24" high. The berm will be located approximately 3 to V inside the S.W. permit boundary line and is intended to mitigate and prevent storm run -off by allowing storm water to be immobilized then filter and evaporate naturally. If ground water is encountered during mining operations every effort will be made to stop flow and mitigate any future seep. j. The Friederrchs Plt112 site includes no historic water riithts either cmweved. or assumed. Friederichs Pit 112 - Riverside Aggregates, LLC. July 1, 2014 Page 2
