Since the last reporting period, ERRS has continued to stabilize site buildings. Portions of buildings 1012 and 1014 have been removed for demolition and in order to ensure building stability. ERRS has continued soil excavation in the area of concern south of building 912 as identified by the subsurface soil assessment. Basements and vaults within and north of building 924 continue to fill with varying degrees of water and oil of which the oil sources are unknown.
On September 30, 2008 a meeting with City of Chicago Department of Environment (CDOE) representatives was completed with U.S. EPA and START in attendance. The purpose of this meeting was to provide a site update, address potential site issues with basements and subsurface vaults refilling with oil product and water, and general planning moving forward. CDOE is currently finalizing Specs/ RFP and working on procuring a contractor to start demolition on the remainder of the buildings in November or December 2008.
Planned removal activities include the following:
• Continued building stabilization,
• Building 1012 and 1014 demolition,
• Continued 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,
• Further investigation of the north central area in building 924 to determine how product continues to enter in the basement, vaults, and pits;
• Waste profiling to ensure proper disposal, and;
• Building 1012 and 1014 demolition by ERRS in order to begin cleaning and sealing of the 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.
