A Cat GPS D8 dozer was used to place stockpiled structural fill in 18 inch to 24 inch lifts at the Midway fill area near stations
1-10+00 to H2+00. A Cat CS56 smooth drum roller was used for compaction. The structural fill was placed and compacted per
project specification.
A Cat 980 loader,a Cat GPS D7 dozer,and 740 haul trucks were used to remove excess material from the PSSA pond floor.
The material was placed as structural fill at the eastern PSSA/HWY67 ramp. A Cat GPS D6 dozer and a Cat CS56 smooth
drum roller were used for placement and compaction. The structural fill was placed and compacted per project specifications.
Cat dozers cut the slope to rough grade near stations GO+00 to G2+00, JO+00 to J3+00, H22+00 to H30+00, CO+00
to C4+00, DD15+00 to DD16+00,down slope of stations B7+00 to B8+00, and at the PSSA embankment. A Cat
CS56 smooth drum roller compacted the finished subgrade slopes at the PSSA embankment afterwards.
Note:An AMEC field professional monitored structural fill material temperatures placed within fill areas. Average
structural fill temperatures were above 32°F and snow removal occurred prior to fill placement.
Clay(SLF)Processing:
Cameron Site: No clay mining or processing occurred at the Cameron Site. Approximately 244,860 tons of clay/
soil liner fill(SLF) material have been produced at the Cameron site. SLF produced from the operation remains
stockpiled at the Cameron Site for future use.
Squaw Gulch Clay Borrow Site: Clay mining and processing took place at the Squaw Gulch Clay Borrow Site.
Approximately, 110,500 tons of soil liner fill material has been produced at the Squaw Gulch Clay Borrow Site to
date.
Underdrain System:
Primary Underdrain: No work occurred on the primary underdrain.
Secondary Underdrain: No work occurred on the secondary underdrain.
Tree/Slash Grubbing and Clearing,Chipping:
No clearing or grubbing occurred.
B) Underground Workings
• Confirmatory Drilling
Confirmatory drilling occurred at underground working#U6115 and#U6273. Further remediation efforts are
required.
Drill access was constructed to underground workings#6112,#6119, and#6508. Confirmatory drilling is pending.
• Remediation
Underground working#U6114 and#U6391 were removed during cut operations and are considered remediated.
Underground working UG#6276 extended into the''/2:1 slope. Structural fill was placed in the opening of the alit
with a Cat 320 excavator. The working is considered remediated.
Underground workings#U6428,#6439,#6440,#U6441,#6494,#6495,#6498,#6500,#6501,#6515,#6516,
#6517,#6518,#6519,#6528, and#6529,were excavated to competent rock, backfilled with structural fill, and are
considered remediated.
Ames worked on exposing an adit and removing timbers at underground working#U6461 using a Cat 330 excavator
with a bucket and a Cat 330 excavator equipped with a rock hammer. Additional remediation efforts are required.
