The excavator continued until 4 pm on the oversize reject pile. (1) Hundai 480LC and (1) CAT D6 dozer continued screening operations. The Hundai 480LC was used to load soil from the east end of Stockpile 2 into the Power Screen screening plant. Screened product was stockpiled in a cone using a belt stacker to keep the screened soil separate from unprocessed soil. The oversize material was recycled back into the stockpile after brief track walking with the D6 dozer. The Contractor reported 1,525 tons of material screened today. A sample was collected for field sieve analysis. Results of sieve testing of a sample collected yesterday indicated 100% of the material was finer than 1 inch. LCRS Gravel Placement: Up to 17 tandem end -dump trucks began delivery of LCRS gravel this morning. Initially the material was very clean, but after a few loads, some contamination was observed in the loads. Occasional dirty loads continued throughout the day.
