An <br />Ames CAT D -10 dozer was used to maintain the borrow area. A CAT 992 and CAT 988 front -end <br />loader were used to load overburden fill material into 777 haul truck's and CAT 40 -ton articulating <br />haul trucks. <br />Overburden fill was placed in the areas shown on Figure 1. DCF depth was checked by survey <br />and the area was approved prior to fill placement above DCF. Overburden fill was placed in 36" <br />to 40" lifts using various CAT dozers. Each lift was moisture conditioned using a tandem axle <br />water truck (when necessary) and compacted using a 10 -ton vibratory smooth drum compactor, <br />passing over the entire fill surface at least 4 times (method compaction technique was applicable). <br />Temperatures were monitored by an AMEC field representative prior to fill placement when <br />ambient temperatures were below 32 °F. Fill material was not placed until the entire fill area was at <br />or above 32 °F. Fill temperatures averaged between 33 °F and 42 °F. <br />B) Slope Contouring <br />Slope contouring of placed overburden fill was performed using a CAT 330 excavator. Material <br />generated during slope contouring was placed as overburden fill at the top of the slope. <br />C) Soil Liner Fill (SLF) <br />Soil liner fill placement is complete for the Mill Site Earthworks project.
