2.1.1 Current Activities
- ERRS excavated an additional 6-10 inches of soil in areas at the southwest corner of the Walp Trucking property (location of samples C-001 and C-002). Confirmation samples were collected from these areas and analytical results show that the samples contain PCBs at concentrations less than 1 ppm.
- ERRS excavated soils to a depth of approximately 24 inches in the northeast corner of the site near Transportation Drive. Approximately 78 large capacitors were uncovered while excavating in this area. To date, a total of approximately 88 large capacitors and 2 small transformers have been found and are being stored on site in drums pending disposal.
- ERRS continued transporting soil off site for disposal. A total of 33 truckloads (approx 757 tons) of PCB contaminated soil was transported off site during the week of Oct 19-23. A total of 21 truckloads (approx 482 tons) of PCB contaminated soil was transported off site during the week of Oct 26-30. All waste was transported for disposal as PCB Remediation Waste at Wayne Disposal Waste Treatment in Belleville, Michigan. To date a total of 63 truckloads (approx. 1,433 tons) of PCB Remediation Waste have been transported off site for disposal.
- Contractors contacted PA One Call and conducted a ground penetrating radar (GPR) survey in areas of the parking lot where excavation is planned. Utility lines were identified and marked.
- START conducted air monitoring for particulates. No action levels were exceeded.
- ERRS cleared trees and debris in parts of the southwest corner of the Walp Trucking property in preparation for planned excavation.
- Removal activities have cut-off a drainage ditch that ran through the site. Water is now being pumped from a collection pond located prior to the drainage ditch to a culvert pipe that allows water to drain off site. Water is being pumped through a filter bag to remove sediments.
- ERRS scraped approximately 6 inches from the surface of an access road that runs adjacent to the drainage ditch. This area was previously determined to not contain PCBs greater than 1 ppm. However, surface contamination is believed to have resulted due to use of this path to transport contaminated soil across the site.
- START collected samples from the parking lot, the drainage ditch and the area where water drains on the opposite side of Transportation Drive. Results are expected next reporting period.
