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 operation of the water treatment plant (WTP) and discharge to the sewer;

  • Continued excavation and installation of the cement/bentonite (CB) slurry trench for installation of the support of excavation (SOE) wall sheet piles:
  • None installed to final depth (48 feet below ground surface); and
  • 282 of 629 linear feet installed to date

Upcoming activities:

  • Relocate and expand the temporary containment building (TCB) over the SOE wall area in preparation for conducting the deep excavation;
