SUMMARY:
DERR arrived on-site at 10:15 AM and met with representatives from Geosyntec. A safety briefing
was conducted with the contractors. The goal of the day was to remove both in-ground hydraulic
lifts, located near MW-5 and GP-5. EnviroCare was on-site to help with properly disposing the
hydraulic fluid.
The DERR observed the removal of the first lift by MW-5. No previous impacts were reported in
this area. The soil around the lift was excavated and disposed of. Excavation occurred down to the
groundwater. There was a hole in the bottom of the lift as the lift was being pulled out, with some
sheen observed in the groundwater. This sheen was also removed with the excavation. Samples
were collected from each of the sidewall and base of the excavation, and homogenized in a large
Ziploc bag. The DERR had Geosyntec collect one split sample from the east wall.
When draining the hydraulic fluid from the lift into one of the containers provided by EnviroCare,
the lift tipped and knocked over the container, spilling the contents (approximately 1/5-1/4 full).
The spill was limited to the concrete and EnviroCare worked to clean it up on-site. Padding used
to soak up the spill were placed in the EnviroCare container. EnviroCare were later observed
cleaning the inside of the lift with a pressurized liquid from their truck, localizing it to where the
spill occurred, and using the same method to absorb the liquid.
The DERR observed the removal of the second lift, located near GP-5, which has known impacts
of oil and grease at depth. The lift was strapped to the excavator bucket to allow for it to be drained
directly into the EnviroCare container. Samples were collected for the base and each sidewall of
the excavation.
Dust control practices were implemented. The excavator bucket was washed before collected soil
for sampling, and other decontamination procedures were observed. Trucks leaving the site with
soil were covered with a tarp.
