The design for the basic program is shown in the five <br /> drawings which were left with the Department at the close <br /> of our meeting. A sixth drawing is enclosed herein and <br /> describes the general geology. <br /> The drawing "Asbestos Disposal Preliminary Proposal, Plot <br /> Plan" (M. Ley, 6-29-88) shows the location of the disposal <br /> site relative to the boundaries of the mine property• <br /> Access to the mine is controlled at the mine entry gates. <br /> The disposal site is about one half mile from the Arkansas <br /> River, which is the nearest stream and about 3/4 mile from <br /> the closest property boundary. <br /> The enclosed drawing, "Generalized Geology of the Climax <br /> Area" taken from the current Climax - reclamation plan, <br /> shows the general geology of the area. The ventilation <br /> shaft is in a metaphorphic, granite formation. There are <br /> no faults running through the location. <br /> The drawing "Asbestos Disposal Preliminary Proposal, Site <br /> Location" (M. Ley, 6-29-88) gives a closer view of the <br /> site. The disposal site is in very steep terrain which <br /> can be accessed by only one road. The road is a dirt road <br /> which must be plowed for most of the year to keep it in <br /> service. <br /> r <br /> The ventilation shaft is 10 feet in diameter and more that <br /> 660 feet deep. The collar consists of a steel liner plate <br /> which extends about 70 feet from . the surface down through <br /> clay, loose boulders and weathered granite into competent <br /> bedrock. (Details of the liner are shown in the drawing <br /> "CAVR Chronological Section as being Mined by Frontier <br /> Const. , " Drawing No. lOg 6-1 ) . The remaining 590 feet of <br /> the shaft are in bedrock. <br /> The drawing "600 Level Crushing Area Exhaust Vent Raise <br /> ( C.A.V.R. ) , 600 Level to Storke Level, Asbestos Dipsosal <br /> Preliminary Proposal" (M.Ley, 6-29-88) shows the <br /> modifications that will be made to the shaft to make it <br /> acceptable for asbestos disposal . After the shaft is <br /> taken out of service, open pit waste rock will be dumped <br /> into the shaft until the rock reaches just above the <br /> bottom of the shaft. A concrete plug of two foot minimun <br /> thickness will then be poured onto the top of the rock to <br /> seal the bottom of the shaft. A minimum 1 foot thick <br /> concrete bulkhead will also be placed in the Storke Powder <br /> horizontal drift to isolate that drift from the disposal <br /> shaft. <br /> Proposed modifications to the C.A.V.R. building, which <br /> encloses the top of the shaft, are shown in the drawing <br /> "Asbestos Disposal Preliminary Proposal, C.A.V.R. Building <br />
