DMG has inspected <br /> the site and is in agreement that reclamation was completed <br /> according to the Consent Decree work plan and MLR standards. <br /> Progress pictures are attached. <br /> - Gold Prince - Mill Tailings <br /> Mobilization for and completion of this project occurred <br /> during the 3rd quarter. The site was inspected for completion <br /> according to the Consent Decree amended work plan and MLR <br /> standards on September 22 , 1997. <br /> Work completed during the 3rd quarter of 1997 at this site <br /> includes; <br /> 1) construction of the adit bulkhead, installation of portal <br /> timber sets, and closure to entry by placing timber <br /> lagging on the interior timber set. <br /> 2) realignment of the County Road through the site to make <br /> room for the consolidated waste pile and stripping of soil <br /> material from the expansion area for later use as capping <br /> material. <br /> 3) construction of a containment area for the onsite tailings <br /> from mine waste with drains under the mine waste to allow <br /> any seeps or springs that may exist in this area to pass <br /> under the mine waste. <br /> 4) lining of the containment area by placement of a 40 mil <br /> PVC liner material underlain by geotextile material to <br /> protect the liner. <br /> 5) placement of tailings and coal ashes from T-1, T-2, and <br /> T-3 into the lined containment with alkaline material <br /> added to provide pH neutralization. <br /> 6) placement of 40 mil PVC liner material over the tailings <br /> and ash material to complete containment. <br /> 7) placement of mine waste from waste piles w-1, w-2 , w-3 , <br /> w- 4 , w-5, and w-6 over and around the lined containment <br /> area to consolidate the mine waste material and create <br /> contours resembling a historic mine dump to preserve the <br /> cultural and historic aspects of this site. Alkaline <br /> material was also added to this consolidated material <br /> although acidic conditions were not found. <br /> 8) capping of the top surface of the consolidated pile with <br /> soil material stockpiled for this purpose. <br /> 9) amending with limestone, seeding with a high altitude seed <br /> mix (mix sheet attached) , fertilizing, and mulching with <br /> hay, the capped areas and disturbed areas where waste and <br /> tailings material were removed. <br /> 10) construction of an upland diversion ditch to divert runoff <br /> around the mine waste. <br /> 11) diversion of the stream flow crossing the Hanson Mill <br /> waste area back into the original stream channel. <br />
