1 1 1 ' gXH I T D ~B r!linin P l an .. _ ,__ ..._.. ... p__ . . ' The Airport Pit 3 application is a continuation of the nriningi that Monks Construction is presently doing on the property. Tn ' fact, the Airport Pit 3 property is owned by the same person that owns Airport Pit 1. The sand and rack to be mined in Rir^por•t Pit ~ 3 is the same alluvial deposit which is presently being minetl. The rasour•ce itaeif is about a 20 to 23 foot thick layer of sand ' and round rock which varies in ^ixe from 2 inches up to 1E.S inches. ' The mining will be a dr•y operation. The water table here is very deep and no water will be encountered. Excavation will be performed by powered scrapers which will r•emave and haul the raw resource to a processing plant. Rs shown in Exhibit C, this ' pr•ocessinp plant will move with the mining operation in phases. The ^crapers will deposit the material 1n a surge pile. A front and loader will deposit the material fr•am the surge pile into the ' crushing and screening plant. After crushing and screening, thtr products will either- be hauled off site or will be further processed by washing or used in the production of port land cement t concrete or asphaltic concrete. T'he processing site itself will involve approximately five (3) acres. The applicant anticipates that in later phases of the mining, a t concrete batch plant or an asphalt 6ntch plant may be desirable. Either oT these plants can fit within the five (3> acre ' processing plant envelope. The site itself contains very little overburden. Visual inspection reveals that cobble and rock fragments are on the ' surface of the entire property. Phases one through five which overlook Eight Mile Crerk contain no overburden. As you move east on the property, more overburden is encountered. In these areas there 1s some strippable overburden which wi1L 6e ' stockpiled. The ma~or•ity of the material used for- backfilling will come from non-marketable and rejected fines from the ~ processing plant. We anticipate this to be between 13% and 20% ' of the total material processed. This amount of fines will be more than adequate far- the backfilling and reclamation of the cite. ' Since no water- will be encountered in the operation, no water impoundments or^ ponds will be ce•sated. ' The mining operation will involve tan (1@) aer•es of land per• year. We anticipate that each phase will require between two (E) years to four- (4) years. Following is a ta61e showing the ' maximum amount of disturbance at any given time.
