Update for the Week Ending July 22, 2016

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:
    • 33 trucks; 925.96 tons shipped last week; and
    • 9,028.19 tons shipped to date.
  • Continued crushing clean excavated material for reuse as backfill in the deep excavation;
  • Conducted shallow excavation and backfilled select fill with compaction on the east and west sides of the support of excavation (SOE) wall; and
  • Continued installation of dewatering wells inside the SOE wall in preparation for the deep excavation.

Recently completed activities:

  • Completed cutting the SOE wall sheet piles to grade in order to relocate the Temporary Containment Building (TCB) over the deep excavation area; and
  • Relocated the TCB from the southeast corner of the Site westward over the SOE wall in preparation for conducting the deep excavation.

Upcoming activities:

  • Expand the TCB northward over the SOE wall (from N. 11th Street to N. 12th Street) area in preparation for conducting the deep excavation;
  • Install the six vapor management system (VMS) units for the TCB;
  • Initiate abandonment of monitoring wells located within the excavation; and
  • Initiate the deep excavation within the SOE wall.
