- Description
- Project Schedule: The Forest Service expects to award the design contract in late April or early May of 2006, with design completion expected by December. Construction will be solicited as a separate contract upon completion of the project design, and is not expected to begin until the site is accessible in late May or early June of 2007. Project Location: The Juniper mine is located at an elevation of 8,500 feet in the Stanislaus National Forest, Summit Ranger District, about 40 miles east of Sonora, California. Directions: HWY 108 east of Sonora to Forest Service road 5N01, approximately 35 miles, on the right, follow signs to Niagara OHV area. Stay on 5N01 for approximately 12 miles to the turn off for Forest Service road 5N33, the entrance gate to the Site is a few hundred yards up 5N33, which is closed to the public. The 5N33 turn off is between Sardine and Red Rock Meadows. Haypress Meadow, and a cluster of summer cabins, is 1 -2 miles past the turn off. Project Description: A detailed description of the site and planned removal action can be found in the Engineering Evaluation/ Cost Analysis (EE/CA), which is available to perspective vendors on request. The Juniper Uranium Mine Site (Site) is an abandoned open pit uranium mine. After discovery of uranium in 1955, the mine produced an estimated 500 tons of ore from 1956 to 1966. Ore processing was not performed on site. The main site features, including the open pit and three overburden and waste rock piles, encompass approximately 34 acres. The estimated combined volume of the waste rock and overburden piles is approximately 50,000 cubic yards. As described in the EE/CA, the Forest Service plans to consolidate the waste piles and sediments from outwash areas around the site back into the open pit in an engineered Group A mine waste repository. Because of a spring at the bottom of the pit and seeps emanating from the pit head wall, construction of an under drain (drain rock, perforated polyvinyl chloride (PVC) piping, drainage fabric, and sand layer) to prevent groundwater from flowing into the repository will be required. Contaminated material is to be consolidated into the repository in a prescribed order, covered with a 30-mil flexible geomembrane liner, a sand drainage layer and a minimum of 3 feet of clean soil from waste pile #3. Disturbed areas and the final cover material will be graded, blended in with natural contours and revegetated to minimize surface erosion. Because of the partially saturated condition of waste pile # 2, which is the most significant source of waste to be place in the repository, a water treatment system will be required. The repository is expected to generate drainage that will require treatment for a brief period of time after construction. The Forest Service expects to use an on site passive ion exchange to treat drain down from the repository. Design specifications for treatment will be developed based on analytical results of drainage after construction is completed. Brief Hazard Description: (Hazards/Environmental Impacts): Elevated levels of uranium and gamma radiation have been detected in the area of the open pit and waste rock pile #2. Levels of gamma radiation were highest in waste rock pile #2 (125 to 11,500 micro Rem per hour) and the mine pit (30 to 6,500 micro Rem per hour). Uranium was detected above the 1,064 mg/kg recreational Preliminary Remediation Goal (PRG) on the surface of waste rock pile #2. Sediments containing radio nuclides, including Uranium and it’s decay products continue to migrate offsite from the pit and waste pile #2 with spring runoff, frequent summer thunderstorms and windborne dust. Red rock creek and the area immediately around the site are utilized by the public, wildlife and grazing cattle. Sensitive areas immediately down gradient from the site include Red Rock and Sardine meadows. No Pre bid tour date will be scheduled.
