Since the last reporting period, ERRS has continued building stabilization activities. Portions of Buildings 912 and 925 have been removed in order to ensure building stability. The integrity of remaining buildings has been assessed. Damage done to Building 1014 has made it unsafe for entry. Work in this building will cease until the City demolition is completed.
START completed a subsurface soil assessment on August 21, 2008. Laboratory analytical results are anticipated during the next few weeks.
On August 27, 2008 a site walk with representatives from the City of Chicago was completed. Although a start date for Site work has not been determined the city is hoping to expedite demolition contractor procurement and start work as soon as possible.
Planned removal activities include the following:
• Continued building stabilization,
• Sampling and pumping of materials within the vault south of Building 912,
• Surgical soil excavation in areas of concern as identified by the subsurface soil assessment, and;
• Cleaning and sealing of PCB impacted floors pending safe building entry
The following actions are anticipated to occur during the next reporting periods:
:
• Reassess buildings for structural integrity,
• Review subsurface analytical results to determine lateral and horizontal extent of metals, PCBs and petroleum hydrocarbons,
• Determine areas for soil excavation and removal, and;
• Waste profiling to ensure proper disposal.
• • Documentation and photo-documentation of all EPA and city work,
• Address contaminants of concern throughout the site based on findings from the subsurface investigation,
• Tracking of excavation and disposal quantities, including soil and water.
