I <br />C <br />of reducing the existing slopes to a non-hazardous and stable con- <br />dition. The portal liner will be steel and placed in a cut in the <br />road. The road bed will be replaced over the portal. It is antici- <br />pated that solid rock will be encountered without disturbance of the <br />slope above the road, If any disturbance of the slope occurs. it <br />will be graded and reseeded according to the recommendations of the <br />SCS. At a later date, two ventilation raises will be necessary. <br />An old mine shaft is near the location for one of these raises and . <br />if possible it will be used for ventilation. Near the second site, <br />the Bureau of Mines excavated a trench in years past which remains <br />unreclaimed. It may be possible to utilize this trench as a site <br />for drilling a ventilation raise. If this is passible, regrading <br />and reseeding of the site will improve an existing disturbed area. <br />If it is impractical to use the trench and the existing shaft site <br />for the ventilation raises, small areas will be stripped of topsoil <br />and leveled for drill pads. A steel liner will be inserted in each <br />raise, backfilled, graded and reseeded as recommended by the SCS. ' <br />When the area is finally abandoned, a bulkhead will be placed in the <br />steel liner, a concrete plug poured on the bulkhead and the surface <br />graded and reseeded. <br />4. Carlton. Tunnel Portal Area - The area of disturbance <br />at the Carlton Tunnel Portal will include the relocation of the ex- <br />isting county road on land. owned by the applicant, the construction <br />of settling ponds for the discharge water from the Carlton Tunnel <br />and addition of material to the existing waste dump. <br />The county road will be moved away from the existing <br /> <br />waste dump and relocated closer to Four Mile Creek.
