station 85+00 of the ADR haul road. The material was placed as structural fill on the former Ball
Mill access road by a Cat dozer and compacted with a smooth drum roller.
Two Cat dozers were cutting the slope at the Ball Mill crossing south of the ADR Haul Road a`
station 87+00. The material was pushed down slope and spread as structural fill upslope of
stations J12+00 to J14+00. The structural fill was placed per project specifications but still
requires compaction.
Processed undersized riprap material was transported between stations 20+00 and 25+00 on the
ADR haul road. Some washed out low volume fill material was also hauled from the PSSA floor
to the area. The material was placed as structural fill by a Cat dozer and compacted with a
smooth drum roller.
Stockpiled cut material from slope grading near ADR Haul Road station 15+00 was transported to
Bench F near station F20+00 and placed as structural fill.
Subgrade:
No new subgrade was accepted during this reporting period. See the attached figure of accepted
subgrade in the Phase 1 area.
Soil Liner Fill:
Excess soil liner fill was removed from Bench B.
Soil liner fill (SLF)was spread by a Cat dozer in an approximate nominal 1.2 to 1.3 foot loose-lift
above Bench B between stations B2+00 to B8+00. Portions of the SLF surface were compacted
by a smooth drum roller per project specification.
SLF Processing:
Cameron Site: There was no SLF processing activity at the Cameron Site during this reporting
period.
Underdrain System:
Primary Underdrain: Complete.
Secondary Underdrain: No work was performed during this reporting period.
Tertiary Underdrain: A Cat excavator and hammer hoe worked on trenching for tertiary
underdrain above Bench B station B16+00 in the Phase 1 area.
B) Underground Workings:
Underground working UG#6588 was blasted. Additional remediation is required.
Workings UG#6117, UG#6153, UG#6551, and UG#6579 were plugged with concrete.
Concrete cylinders were cast for strength testing. Additional remediation is required.
C) Geomembrane:
PSSA
Primary 100-mil DSMS LLDPE Liner Installation
ECA installed 100-mil LLDPE smooth geomembrane in the PSSA. Panels P-373 through P-429
were deployed on accepted LVSCF. Twenty full rolls and multiple partial rolls of 100-mil LLDPE
smooth geomembrane were deployed yielding 7,236 lineal feet of fusion welds for an
approximate installed weekly total of 129,553 square feet. Quality control was performed using
