At the request of Kim Jones (ERRG), the Galli Group was onsite to perform nuclear density testing of the soil "cap" (brown, silty Sand w/gravel) on the disposal cell at the Blue Ledge Mine removal project on 1060 Road in the Rogue River National Forest.

A total of six density tests were conducted. Three tests in the "cap" fill section (85% plus or minus 2 % compaction specification), and three tests in the road sub base (95% compaction specification) along the east side of the disposal cell. A sample of the fill material was collected for lab testing (ASTM D 1557 Method C). Based on the maximum laboratory dry density of 134.2 pcf, the test results indicated that the fill material for the "cap" was compacted to between 86 and 92 percent and the road subbase was compacted to 93 percent. Kim was informed of the test results. Please see the attached Field Compaction Tests sheet for specific test locations and results.
