ame <br />Earth & Environmental <br />centerline; and between stations J7+00 (+/-) and J12+00 (+/-), approximately 0 to 100 feet <br />right of centerline. Slope contouring was performed using various CAT dozers and various <br />CAT excavators. The material generated as the cut progressed was pushed down the slope. <br />D) Overburden to Stockpile <br />1) VLF <br />No work performed during the week. <br />E) Cut to Fill <br />1) VLF <br />A CAT 385 excavator was used to excavate structural fill material between stations E9+50 <br />(+/-) and E13+00 (+/-), approximately 20 feet left of centerline to 50 feet right of centerline <br />and J4+00 (+/-) and J10+00 (+/-), approximately 20 feet left of centerline to 20 feet right of <br />centerline. The structural fill material was loaded into CAT 777 haul trucks and hauled to fill <br />areas. <br />Structural fill was placed between stations A60+00 (+/-) and A64+25 (+/-), approximately 50 <br />feet left of centerline to 20 feet right of centerline and between stations C0+00 (+/-) and C7+00 <br />(+/-), approximately 60 feet left of centerline to 60 feet right of centerline. Structural fill was <br />placed in 18" to 24" lifts using various CAT dozers. Each lift was moisture conditioned using a <br />CAT 773 water truck (when necessary) and compacted using a 10-ton vibratory smooth drum <br />compactor, passing over the entire fill surface at least 4 times (method compaction technique <br />was applicable). <br />Blast pattern drilling was performed between stations E7+00 (+/-) and El 1+00 (+/-), <br />approximately 0 to 75 feet right of centerline. Blasting was performed on Monday (5/24/2010) <br />and Tuesday (5/25/2010). Blasting was not performed Wednesday (5/26/2010), Thursday <br />(5/27/2010), Friday (5/28/2010), and Saturday (5/22/2010). <br />F) Soil Liner Fill <br />1) VLF <br />Moisture conditioning of in-place SLF continued between stations B3+00 (+/-) and B10+00 <br />(+/-), approximately 0 to 600 feet right of centerline. A CAT D-6 dozer with a disc attachment <br />and a tandem-axle water truck were used to process the SLF, raising the moisture content. <br />Compaction of the SLF was performed using a 10-ton vibratory smooth drum compactor. <br />Nuclear density testing, moisture verification, and depth checks were performed in the <br />geomembrane deployment areas throughout the week. All test results were within project <br />specifications and all test locations were surveyed by Ames. <br />G) PSSA Ore Slope Construction <br />Construction of the remaining portion of the PSSA ore slope continued between stations G4+00 <br />(+/-) and G10+00 (+/-), approximately 0 to 225 feet left of centerline using a CAT D-6 LGP dozer <br />and a CAT 279 skid steer loader. Existing ore was pushed over the previously certified secondary <br />geomembrane, constructing the toe of the slope. Geotextile was placed over the geomembrane <br />within three feet of the slope toe. An AMEC field representative observed slope construction <br />constantly. A 10-ton smooth drum roller was used to compact the surface of the ore slope 2' or <br />VLF Weekly Report WE 05.29.10.D
