Since the last reporting period, ERRS has halted prepping and sealing activities on the PCB impacted floor of building 1014, with an estimated two hours of work left until completion of the second epoxy coat. Excavation of the interior of the test trench and associated oil intrusion investigation activities has been completed in building 924. ERRS encountered oil-saturated soils and oil-containing pipes in this area during the investigation, which are the presumed sources of the oil intrusion in the building 924 basements. The excavation south of building 912 has begun being backfilled with brick materials stockpiled on the southwest side of the site, which originated from building 912 demolition activities.
SAMPLING ACTIVITIES
On April 29, 2009 ERRS collected three wipe samples from the frac tank in Building 924 for PCB analysis. The samples were sent to Test America in North Canton, OH and analytical results are pending.
|
|
Planned removal activities include the following:
• City of Chicago demolition of remaining buildings;
• Haul out soil stockpiles resulting from the excavation activities inside of building 924 and south of building 912 for disposal;
• Completion of sealing the PCB impacted floor at building 1024.
|
|
The following actions are anticipated to occur during the next reporting periods:
• Reassess buildings for structural integrity;
• Backfill the soil excavation south of building 912 from the area of concern as identified by the subsurface soil assessment and the surgical soil excavation inside building 924 from the investigation of the subsurface oil intrusion source;
• Waste profiling to ensure proper disposal, and;
• Completion of the sealing activities on the building 1014 concrete floor.
|
|
• Documentation and photo-documentation of all EPA and city work,
• Address contaminants of concern throughout the site based on findings from the subsurface investigation, and;
• Tracking of excavation and disposal quantities, including soil and water.
