<br /> <br />EXHIBIT D <br />GENERAL SPECIFICATIONS OF 'fHF. M]NING PL:\N <br />I. Purpose of the Material Site: <br />4. General use: <br />t. Pit run for road or dike subbase <br />2. Classified or crushed material for road surfacing or <br />for water conveyance, channel lining, etc. <br />3. Re,leci 3/4 minus with plasticity and crusher fines <br />ample to quality for road surfacing while crushing clean chip, <br />for Asphalt pad or Trot sealing a highway. <br />B. Final location of produced material <br />1. Highway work under contract with Federal, State, or <br />local agency. <br />2. Dirt roadway surfacing on County Roads through out <br />the County. <br />3. Dikes and canals or other water conveyance channels. <br />C. Tenw•e: <br />1. The pit <br />period of tune. Staged <br />the long form effects. <br />a. The <br />materia] are needed. <br />immediate. Nu stockpiles <br />for over three years <br />will he used anmtall>~ for a indefinite <br />production and reclamaton will mitigate <br />Estimated life of the pit in 211 years. <br />produced stockpiles will be removed as <br />Under some "contr;;rl" removal will be <br />Ihai are over 15' bc•i~ht wrl] be remain <br />II. Reclaimation Materials: <br />A. Top Soil: <br />Ample topsoil (approximately 12") will be removed and <br />stockpiled error to rernova] of the uuderlyiu~ waterial.^> <br />(subsoil soil, and production materialsl. Stockpiles will be <br />placed out of the way of excavation and production stockpiles. <br />They will not exceed twelve (12) feet in height and will be <br />buffered with enough area to allow equipment to work between the <br />piles and the outside boundary and. For tcrading u1' d:I slopes nn <br />the inside during staged reclamation (this includes subsoils and <br />spoil stock piles). <br />1. Enough subsoil will be removed to adequately cover fhe <br />reclaimed area with a minimum of 10" of subsoil. <br />2. This material is the calcium carbonalr• rune and contains <br />fines, both of which are needed to establish ;atisi'.,ctory rc~vcge- <br />tation. 'f he materials are also needed for roust produced waferials <br />to meet gradation specifications. See Item D for a possible <br />solution to this problem. <br />C. Spoil: <br />Overburden and oversized materials not needed for <br />production will be stockpiled with the same requirements a:; K. <br />subsoil above, omitting items 1 and 2. <br />
