Ames conducted Phase Na, b, and c construction activities on twelve days of this fourteen-day reporting period. Phase Na Ames conditioned and re-rolled the Soil Liner Fill (SLF) south of the currently in-place geomembrane. The SLF in this azea had failing moisture contents on several in-place tests. Ames used a CAT 330 Excavator with a rake attachment to break up the SLF and several water truck loads were used to moisture condition the SLF. Oversize materials were observed in the SLF after the area was re-worked. Random test pits were excavated by hand to determine the extent of oversized materials. It was determined that oversized material was from the subgrade and that it was present in the SLF over an azea that was approximately 120 feet wide and extended down the entire slope length.
