2.1.1 Narrative/On Site Activities
April 25 – Equipment support request provided to ERT West; air monitoring
instrumentation will be provided on loan at least until additional resource
acquisition can occur. Representative for the lessor of the haul road
arrived on-site to discuss road improvements on southern extent of haul road
connecting Highway 3 SW. ERRS continued segregating and stockpiling
surface debris on the landfill in preparation of initial excavation activities.
Containment cell construction also on-going; the number of containment cells in the
stockpile area reduced to seven (7) due to area limitations.
April 26 – Construction activities from previous day continued. START
performs background gamma radiation survey on accessible portions of landfill
and perimeters of stockpiled surface debris. START collected ambient
radiation levels which were within typical background readings for this
geographic location. Containment cell liners arrive on-site; construction
begins on containment cell nearest to landfill. Pump contract awarded for
creek diversion purposes.
April 27 – Construction activities from day
previous continued. ERRS acquires grass seed for seeding temporary borrow
near the command post. Security fencing arrives on-site and initial sections
consisting of gate and adjacent portions were installed at the northeast corner
of the site on the access road along the northern adjoining property. EPA
coordinates with the Pacific Strike Team (PST) for site personnel.
April 28 – EPA, START, and ERRS met with the lessor providing site access
from Highway 3 SW regarding issues pertaining to the lease agreement. A
health and safety drill was performed utilizing escape packs to be deployed
around the landfill for operators and technicians working in the excavation area.
ERRS completes temporary fence installation on northeast boundary of site along
Highway 3 SW.
April 29 – Construction activities from the previous day continued.
Two Fish and Wildlife Service personnel arrived on-site a provided two
time-lapse cameras to support site documentation activities. START
completed GPS data collection of site features on the haul road, command post,
and stockpile area.
April 30 – Construction activities from previous day continued; final block
of containment cells completed today. All cells awaiting placement of the
high-visibility liner to be placed on top of containment cells; however,
placement of this layer will occur at a later date, but prior to placement of landfill excavation material with
no sand layer between it and the high-vis layer.
May 2 – ERRS continued construction of the final cell in the stockpile
area. Two to four inch crushed stone was received for road construction in the
stockpile area and command post. The roads were compacted with a vibratory
compactor to accommodate haul trucks during the excavation. START and ERRS
discussed sample equipment procurement and analytical requirements.
May 3 – ERRS continued construction of the final cell and extending the
road in the stockpile area with crushed rock. Two representatives from the PST
arrived on site. The excavator was used to construct a pad using two to four
inch crushed rock as a base for the bypass pumps in the impoundment. Equipment
from ERT West was delivered to the site, including multiple AreaRae instruments
and a Viper telemetry system.
May 4 – Activities from the previous day continued, including
construction of the final cell and extending the road in the stockpile area
with crushed rock. The excavator was used to improve access to the bypass pump location
in order to connect pipes to the pumps later in the week. At approximately 5
am, a stolen vehicle was driven onto the site via the south access point and
abandoned at the western access point. The on-site security reported the
incident to ERRS, and a sheriff deputy stopped by the site to collect
information. No items were reported stolen, and the only damage was to the
fencing and gate.
May 5 – ERRS connected the pipes leading from the bypass pump in the
impoundment, and continued the pipe connection along the access road adjacent
to the Airport Auto Wrecking property located to the north of the Site.
Approximately 130 sandbags were shuttled to the base of the landfill on the
downstream side to form a settling pond. A START engineer arrived on site to
observe the pipe connection and settling pond construction. Crushed rock was
delivered and stockpiled at the site for construction of haul roads later in
the week. A cylinder designed to hold propane was discovered along an access
road. At 1330 hours, an adult black bear and two cubs were observed on the
landfill. All field personnel were notified of the bears via radio. START and
the PST worked together to strategize daily field tasking and assignments
during the excavation. PST collected GPS coordinates of site features around
the stockpile area.
May 6 – EPA and START discussed the possibility of encountering
asbestos-containing material (ACM) on site. START collected three air samples
for phase contrast microscopy (PCM) asbestos analysis via NIOSH Method 7400 to
determine baseline concentrations. One sample was collected in the command post
area, and two samples were collected on the top of the landfill. ERRS continued
to connect the sections of pipe for the stream bypass system. Additional
sandbags were prepared for construction of the settling pond. Two Kitsap Public
Health District (KPHD) visitors arrived on site to meet with the OSC. PST
collected GPS coordinates of site features around the landfill, including the
air sampling locations, as well as features in the stockpile area. START
updated a table containing health and safety action levels. Copies of the action level table will be
posted in the work trailers, and command post.
–START collected three air samples for PCM asbestos analysis via
NIOSH Method 7400 to determine baseline concentrations. One sample was
collected in the command post area, one sample in the stockpile area, and
another sample in the landfill. Bulk samples of suspected ACM were collected
from the landfill surface for polarized light microscopy (PLM) analysis via EPA
Method 600/R-93/116. The asbestos analytical subcontract was awarded. ERRS
continued to construct the haul road and build the settling pond for the stream
bypass. PST collected GPS coordinates of site features around the landfill,
including the air sampling locations.
