2.1.1 Narrative/On-Site Activities
Monday,
August 29
● ERRS continued to excavate in the landfill and loaded waste into Containment Cells 5 and 6.
● START collected three composite samples from Containment Cell 5. These samples, along with samples from Containment Cell 4 collected on Saturday, were delivered to the off-site laboratory by private courier.
● START collected three post-excavation samples (PE-14, PE-15, and PE-16) from the north slope of the excavated landfill, below AAW and to the east and SE of previous PE samples. Samples were delivered to the off-site laboratory by courier.
● ERRS began to regrade and backfill the NW corner of the excavation area (including the Airport Auto Wrecking property) using the existing clean slopes.
● START and USCG performed air monitoring with AreaRAEs, MultiRAEs, DataRAMs, and DustTraks and collected air samples for asbestos and lead. Air monitoring results were below action levels and within normal limits.
● The lead START engineer was on site and discussed the draft STORM plan with EPA and ERRS.
● Off-site laboratory results were received for lead air samples collected previously; all results were below site action levels.
● START submitted a weekly equipment report to the OSC, which includes an inventory of assets from the following sources: EPA Region 10 Warehouse, EPA Region 10 Manchester Laboratory, EPA ERT-Las Vegas, EPA ERT-Cincinnati, EPA ERT-New Jersey, USCG Pacific Strike Team, and WA Department of Fish and Wildlife, as well as assets purchased for use by site funds.
Tuesday, August 30
● ERRS loaded trucks and trailers with non-hazardous waste for off-site transportation and disposal from Containment Cell 7.
● ERRS continued to excavate in the landfill and loaded waste into Containment Cell 6.
● A load of steel was sent off site today for recycling.
● START collected two more post-excavation samples (PE-17 and PE-18) from the north slope of the excavated landfill. Samples for PCBs were delivered to the off-site laboratory by private courier. Because of a temporary delay with total metals analyses at the local laboratory, these post-excavation samples for metals were shipped via overnight courier to an alternate laboratory. Additionally, START collected a sample of the borrow source material for metals analysis, which was also shipped to the off-site metals laboratory.
● ERRS continued to regrade and backfill the NW corner of the excavation area (including the Airport Auto Wrecking property) using the existing clean slopes.
● START and USCG performed air monitoring with AreaRAEs, MultiRAEs, DataRAMs, and DustTraks and collected air samples for asbestos and lead. Air monitoring results were below action levels and within normal limits.
● Off-site laboratory results were received for an asbestos air sample submitted for transmission electron microscopy (TEM) analyses; the result was non-detect.
● START shipped air samples collected from August 25–29 for lead and asbestos analyses to the respective off-site laboratories.
● A representative from Washington Ecology's mercury program, who is knowledgeable about PCB regulations, visited the site and received a tour from the OSC.
● A representative from the Kitsap County Parks Department visited the site to assess the recovered pieces of granite for potential re-use at local parks.
● The geotechnical engineer was on site to perform compaction testing of areas being backfilled. The results indicated 90% compaction, which is right at the minimum recommended. The soil moisture was a little less than optimum, so he recommended that ERRS add more water during compaction.
● TCLP volatiles results were received for the drum of resin discovered last week; all results were non-detect.
Wednesday, August 31
● ERRS loaded trucks and trailers with non-hazardous waste for off-site transportation and disposal from Containment Cells 7 and 8.

● START collected two more post-excavation samples (PE-19 and PE-20) from the northwest slope of the excavated landfill. Samples were delivered to the off-site laboratories by private courier and overnight delivery.
● ERRS continued to regrade and backfill the NW corner of the excavation area (including the Airport Auto Wrecking property) using the existing clean slopes.
● START and USCG performed air monitoring with AreaRAEs, MultiRAEs, DataRAMs, and DustTraks and collected air samples for asbestos and lead. Air monitoring results were below action levels and within normal limits.
● Off-site laboratory results were received for asbestos and lead air samples collected previously; all results were below site action levels.
● Representative of the Kitsap County Public health District visited the site and met with the OSC.
● Several visitors were on site from EPA Region 10 and were given a tour of the removal activities, including the Regional Administrator, the Deputy Regional Administrator, and several office directors. Also attending the site tour were a council member and fisheries biologist from the Suquamish Tribe.
Thursday, September 1

Friday, September 2
● ERRS loaded trucks and trailers with non-hazardous waste for off-site transportation and disposal from Containment Cell 1.
● ERRS continued to excavate in the landfill and loaded waste into Containment Cell 8.
● ERRS continued to regrade and backfill the NW corner of the excavation area (including the Airport Auto Wrecking property) using the existing clean slopes.
● START and USCG performed air monitoring. Heavy rains and thunderstorms were expected today, so air monitoring was modified. The AreaRAEs ,MultiRAEs, and personal samplers for lead and asbestos were deployed, but the dust monitors (DataRAMs and DustTraks) and stationary air samplers for asbestos and lead were not deployed. Air monitoring results were below action levels and within normal limits.
● START shipped air samples collected from August 30–31 for lead and asbestos analyses to the respective off-site laboratories.
● Green and purple liquids (perhaps antifreeze, or dyes) were discovered in the bottom of the excavation area; START collected samples and performed hazardous categorization testing, and the results indicated no characteristics of hazardous waste.
● Results for the PE samples collected earlier this week began to arrive. The PCB results for one sample (PE-17) was slightly above site screening levels, so plans were made to remove additional soil in that area.
● ERRS secured the site for the Labor Day holiday weekend.
Saturday, September 3
● No work today for the Labor Day holiday weekend.
Monday,
September 5
● No work today - Labor Day holiday.
Tuesday,
September 6

into Containment Cell 8, then began loading waste into
Containment Cell 1.

local facilities for recycling.
● START
collected three composite samples from Containment Cell 8. These samples were
delivered to the off-site laboratory by courier.

over-excavated PE17 and PE18 approximately 1 foot due to elevated
concentrations of PCBs. This combined post-excavation decision unit, renamed
PE21, was screened with the XRF and re-sampled for PCBs and metals.
● START and
USCG performed air monitoring with AreaRAEs, MultiRAEs, DataRAMs, and DustTraks
and collected air samples for asbestos and lead. Air monitoring results were
below action levels and within normal limits.

continued to regrade and backfill the NW corner of the excavation area
(including the Airport Auto Wrecking property) using the existing clean slopes.
Wednesday,
September 7
● ERRS

USCG performed air monitoring with AreaRAEs, MultiRAEs, DataRAMs, and DustTraks
and collected air samples for asbestos and lead. Air monitoring results were
below action levels and within normal limits, with the exception of an LEL
alarm in a haul truck in the landfill. START and USCG responded with additional
air monitoring instrumentation, and determined that the alarm was an instrument
fault. The issue was resolved with a fresh-air calibration.
● START and
USCG performed radiation screening in Containment Cell 2 following an EPD alarm
reported by the excavator operator. The operator, excavator, material in the
cell, and trucks being loaded out were all screened with the Ludlum 19 and
2241-2 with pancake probe. No results above background readings were
detected.

below action levels and within normal limits.
● The
geotechnical engineer was on site to perform compaction testing of areas being
backfilled. The initial area tested failed compaction at 89% (minimum
recommended compaction is 90%), and 12% moisture, so that area was re-rolled
and tested again. All remaining locations passed at 92 to 95% compaction and
7-10% moisture. Moisture was above ideal content of 5 to 7%, but it had
recently rained prior to testing, and the rain occurred after compaction.
