ERRS then removed the ramp into the repository and re-excavated where hot spots were identified. In the early afternoon, final grading of the repository was completed and the repository was ready for final segment of liner installation. ERRS placed back fill into the ready line and adjacent slopes and graded slopes for erosion control measures installation and continued installation of the clean road to USFS lands. Northwest Linings laid geotextile and liner, moving westward to the end of the repository. URS conducted QA/QC during deployment of liner cap materials and processed weld samples for shipment to lab for analysis and testing. USFS crew assisted with hand excavation around the repository berm and continued installation of straw wattles and coir matting on the west side mine waste area slopes. START collected 10 samples from Mine Waste Area, 8 samples from USFS lands, and 2 samples from the roads. START analyzed 45 samples with XRF and prepared QC samples from shipment to the Region 9 laboratory. Aramark cook was upset by something that occurred the previous evening and refused to make breakfast and lunch for the entire crew. Cook requested for himself and the prep-cook to be replaced. One ERRS demobilized for personal reasons. Excavator operator fell ill and went back to camp to recuperate.
