Site Remediation Continues

On-going activities:

  • Continued the application of water and calcium chloride for dust control;
  • Continued the application of odor-suppressant foam and BioSolve for odor and dust control;
  • Maintained erosion and sediment (E&S) controls (Installed waddles - wood chip and straw filled fabric tubes - around the Site perimeter to prevent silt and sediment from leaving the Site and covered all stockpiles);
  • Continued pumping from the decontamination pads and excavated areas to the water treatment plant (WTP);
  • Continued operation of the WTP and discharge to the sewer;
  • Continued lining and loading trucks and shipping impacted soil to Bayshore Soil Management for treatment and disposal:
    • 6 trucks; 173.66 tons shipped last week; and
    • 9,801.29 tons shipped to date.
  • Continued crushing clean excavated material for reuse as backfill in the deep excavation;
  • Loaded and transported two loads of clean asphalt to Bayshore Soil Management for recycling;
  • Continued shallow excavation and backfilled select fill with compaction on the eastern side of the Site;
  • Decommissioned four monitoring wells in the eastern areas of the Site;
  • Continued plumbing the ground water extraction wells and sumps with pumps to convey water from the deep excavation area to the WTP;
  • Continued the assembly of the expansion of the temporary containment building (TCB) over the deep excavation area; and
  • Initiated the installation of electrical service for the dewatering pumps and lighting and vapor management system (VMS) for the TCB.

Upcoming activities:

  • Install the six VMS units for the TCB; and
  • Initiate the deep excavation within the SOE wall.
