Cat 740 haul trucks transported material pushed down from the slope above ADR Haul Road
stations 52+00 to 55+00 to stations 88+00 to 92+00 and to Bench K stations K30+00 to K32+00
where it was placed and compacted as structural fill.
Two Cat dozers were cutting the slope at the Ball Mill crossing south of the ADR Haul Road
station 87+00. The material was pushed down slope and spread as structural fill upslope of
Bench J stations J12+00 to J14+00.
Cat 740 haul trucks transported material from the Phase 2 Diversion Channel alignment on Dump
4 near station 38+00 to 46+00 to Bench K stations K30+00 to K40+00 where it was placed and
compacted as structural fill.
Stockpiled cut material from slope grading near ADR Haul Road station 15+00 was transported to
Bench F near station F20+00 and placed and compacted as structural fill.
A Cat excavator and dozer placed cut to fill near Bench I station 110+00 to 112+00 in the Midway
area.
A Cat excavator and a dozer excavated the outbound haul lane near Ames' Gate 2 where it
crosses the Phase 2 Diversion Channel alignment to place temporary piping allowing surface
water to flow from the upper Phase 2 channel under the haul road to the Phase 2 pond.
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 (SLF):
A Cat 330 excavator with a plate tamper attachment was used to build and compact berms using
SLF material on the south perimeter road near Bench P between stations PO+00 to P2+25.
Soil liner fill was spread by a Cat dozer in a minimum 1-foot-loose lift above Bench B between
stations B2+00 to B10+00. A Cat smooth drum roller compacted the finished grade. The soil
liner fill was moisture conditioned.
Soil Liner Fill was accepted for liner deployment from Bench DD to Bench B between
approximate stations BO+00 to B4+00.
See the attached Soil Liner Fill Map for accepted SLF in the Phase 1 area.

Primary Underdrain: Complete.
Secondary Underdrain: No work was performed during this reporting period.
Tertiary Underdrain: Approximately 400 lineal feet of tertiary underdrain was excavated, lined
with non-woven geofabric, filled with underdrain material, and covered with select structural fil
above Bench B station B16+00 in the Phase 1 area. This section of underdrain tied into existing
secondary underdrain at the northeast corner of the PSSA crossing the ADR haul road.
