Gold Eagle Mining Inc. JD -5 Mine Permit Number M- 1977 -248 reclamation plan on file with for the facility will remain effective until other opportunities can be determined in accordance with the DOE's PEIS findings. 7.0 Facilities Evaluation The ore stockpile is located on low - permeability soils which preclude release into underlying material or groundwater. More specifically, in 1980 a report was prepared by Gates & Fox Associates which reported the results of local soil permeability measurement. It was determined in these studies that the soils were variable with a range of in -situ permeability on the order of 5x10 to 9x10 cm/sec; however, remolded similar clay soils were quite impermeable with permeability rates on the order of 7x10 cm/sec, similar to that generally acceptable for clay liners. The locations of the pits where soil was tested are shown on Figure 2. Because the stockpile is located on a nearly flat terrain and there are no nearby drainages, releases to surface water are not possible. While the stockpile could be equipped with containment berms, this activity is currently prohibited by the DOE PEIS process. Given the extensive nature of the pending DOE PEIS it is expected that general conclusions about the nature of materials and the significance of impacts from ore stockpiles on the DOE properties will become available to append to this plan in the near future. This information will be used to guide future monitoring and response needs relative to the JD -5 stockpile. 8.0 Groundwater Information There are no tributary water courses, wells, springs, stock water ponds, reservoirs and ditches, on the affected land and on adjacent lands within two (2) miles, of the existing or proposed affected lands. An extensive data base of regional wells and springs was developed by Gates and Fox and is incorporated here by reference The JD -5 Mine site is located on the south side of Paradox Valley which is over the northwest trending Paradox Anticline. Mesozoic age continental sandstone, shale and mudstone are exposed by the incision of the valley. Geologic units dip at a shallow 2 to 5 degrees towards the southwest. Exposed formations of Mesozoic age within one mile of the JD -5 Mine (from bottom up) include the Jurassic Period - Navajo Sandstone (-200 ft. thick), Entrada Sandstone ( -70 to 90 ft. thick), Wanakah Formation also known as the Summervile Formation (-100 ft. thick), and 4 Environmental Protection Plan -JD -5 September, 2012
