To facilitate such <br />a cohesive narratlva descrlptlon, Clio staff suggests that equipment <br />to Ise used and time tables be Incorporated directly into the narrative. <br />(2) First, the mina plan should clearly explain Cho type and extent <br />of surface disturbance at the present time with the narrative keyed to <br />11ap L. <br />(3) Then the plan should discuss the mining sequence In detail.' <br />(a) descrlptlon of topsoil removal - How much will be removed <br />In Inches? Where wlil topsoi.i be stockpiled and how many cubic yards <br />of topsoil will be stockpiled? How will topsoil stockpiled be stabll- <br />Ized. How long will topsol) stockpiles exist? Will any topsoil removed <br />be placed directly on regraded spoils. <br />(b) descrlptlon of overburden removeal <br />(i) preparation of overburden for blasting. (Blasting procedure <br />In complicate with 30 CFR 715.13)can be discussed in Exhlblt D or In the <br />addendum). <br />(II) overburden excavation ;How much overburden will be removed <br />In feet? Where Trill overburden be stocl;piled tend how many cubic yards <br />of stockpiled overburden will there be7 Iloiv will overburden bo stockpiled? <br />Will any overburden be placed directly bacl: on a mined out area4 <br />(c) descrlptlon of teal removal <br />(1) preparation of coal.for blasting <br />( I i ) coo 1 rerrova 1 <br />(II) hauling of coal to processing area and processing of coal <br />(iv) descrlptlon of coa.1 loadout and treasportas~e0em from site. <br />(4) The mine plan should also discuss: <br />(1) present and proposed facilities qn side and topsoil procedures <br />for these areas <br />(ii) location of disposal areg and nature of refuse material <br />~Xalso rofcr to $0 CFR to 715.15 and 715.17) <br />(111) descrlptlon of excavation of sediment ponds, ditches, Yikes <br />and other surface water management structues, topsoil salvage pro- <br />cedures for these newly disturbed areas and capacity end design of surface <br />mater management structures (rofcr to 30 CFR 715.17 for guidance on <br />- capacities and design requlreents). A map delineating drainage areas . <br />for each sediment pond would be most useful. Stabilization of sediment <br />pond and ditch banks should also be discussed. <br />(Iv) handling of the natLLral qas pipeline In the permit area <br />'~ (v) how dust will be controlled at the site <br />(5) A topsoil balance for the permit area should be discussed. This would <br />Include locating areas and stating acreages where topsoil yasaoetla6liaged in the <br />~~etsaidagiageand topaetiglaraaeliatllatatthg appiigastofhooddoitso locate <br />areas where topsol] is abellable for salvaging and ylve fire cubic yards <br />of salvagagle topsoil and the n wiberoof acres to be retopsotled. The amount <br />of topsoil slavaged should be correlated to a site-specific soil coring <br />artd analysts program (Sec Exhibit 1 for details - also refer to 30 CFR <br />715.16)also see Exhlblt I for more details on the necessity of en over- <br />burden testing program). <br />(6) A detailed geologic cross-section, or several cross sections if ., . <br />necessary, should be presented with precise depths of strata to allow for <br />
