2.1.1 Current Activities
- ERRS continued loading out PCB contaminated soil for disposal. PCB contaminated soil is being transported by truck and rail to Heritage Environmental Services in Roachdale, Indiana for disposal as PCB Remediation Waste.
- During this reporting period a total of approximately 1,976 tons (92 intermodal containers) of PCB Remediation Waste was transported off site for disposal from CLI's property and a total of approximately 1,395 tons (63 intermodal containers) of PCB Remediation Waste was transported off site for disposal from Walp Trucking's property.
- To date, a total of approximately 5,408 tons of PCB remediation waste has been excavated and transported off site from the Walp property. A total of approximately 3,714 tons of PCB remediation waste has been excavated and transported off site from the CLI's property.
- ERRS excavated PCB contaminated soil and backfilled excavations with clean fill in the western portion of CLI's property. Areas were excavated to a depth of 24" to 40" depending on subsurface sample results. In areas were subsurface samples (18" - 24") contained PCB's at greater than 25 ppm, post excavation sampling was conducted to ensure site cleanup goals were achieved. A total 62 loads of clean fill were transported on site during the reporting period.
- START collected 8 subsurface samples to better delineate contamination in the subsurface along the border of the Walp and CLI properties. PCB concentrations ranged from 0.14 to 135 ppm PCBs in the samples.
- START conducted daily particulate monitoring. No action levels were exceeded.
