Monday, September 26 - 27
● Excavation from landfill and filling of stockpiles continued.
Continue to line the downstream creek outfall area with concrete pieces
and PVC liner in preparation for the winter STORM operations. ERRS also began
to excavate the STORM surface water channel through the center of the remaining
● ERRS removed the pumps, generators, and piping that had been used for the
creek surface water bypass system.
● ERRS began to move the chain-link fence between the landfill and Highway 3 to
the perimeter of the excavation area in preparation of winter STORM operations.
● START submitted the updated STORM plan with 2016-2017 winter planting
recommendations to EPA and ERRS.
● 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 lead air samples collected
previously; all results were below site action levels.
● EPA ERT
staff arrived on site to assess the seven cylinders.
START mobilized the EPA Region 10 Level A truck to support the cylinder
assessment and neutralization, and the USCG provided health and safety oversight.
Six cylinders were related to industrial firefighting and confirmed to be
empty; the valves on these cylinders were disabled and the cylinders were set
aside for recycling. The remaining cylinder of suspect acetylene was prepared
for processing on the following day.
● Oct 4 During the afternoon
operations meeting, the following decisions were made: PPE requirements were
downgraded to modified Level D unless task-specific job hazards required
upgrading; no additional fixed or personal air sampling will be performed
during the remainder of the current field event; and, no electronic personal
dosimeters (EPDs) will be issued during the remainder of the current field
● ERT staff prepared
to remotely drill the cylinder of suspect acetylene. The cylinder was successfully
drilled. A de minimis volume of residual acetylene was present in the cylinder
and allowed to vent to atmosphere. Due to concern that the cylinder may contain
asbestos, it was set aside to be shipped off site for disposal as
asbestos-containing material (ACM). START and USCG provided support to ERT
including air monitoring, site setup, and tear down activities.
● START shipped five
cases of equipment used during the cylinder operations to the ERT warehouse in
Las Vegas, NV.
● During the afternoon
operations meeting, the following decisions were made: AreaRAEs will no longer
be deployed; the remaining Air Stations 1, 3, and 5 will be decommissioned; no
particulate monitors will be deployed for the remainder of the field season,
and therefore all Viper-related activities will be discontinued.
