The Site encompasses approximately 36.16 acres and includes a 120,000 square foot vacant building; paved parking areas, grassed areas and lightly wooded areas within a unsecured security fence and in front of the building; and a larger undeveloped wooded area outside of the unsecured security fence extending south to the Roaring Branch of the Walloomsac River (Roaring Branch) and west to adjacent properties. The Site’s current local zoning classification is Industrial.
Hazardous substances include PCBs and asbestos. High levels of PCBs are located in the soil outside and beneath the building, in the concrete slab of portions of the building, and on the steels walls of the building. Asbestos was identified in floor tiles in the building. VT DEC also noted elevated levels of DEHP, VOCs, and Zinc in their Brownsfield report.
During the week of 8/28/2006:
1. Bid walk was conducted for the clearing and grubbing of the immediate area around the JARD building.
2. Site walk and meeting with the ERRS T&D Coordinator and Demolition Engineer. ERRS to research various strategies of disposing of building steel. Demo RFP went out around 9/13/2006.
During the week of 9/18/2006:
1. Tree cutting of the entire facility exterior footprint.
2. Mobilization of all support zone equipment and materials.
3. Mobilization and set up of approximately 700 feet of temporary security fence and 2 sets of gates.
4. Site Walk on 9/20/2006 for the building demo portion of this removal. Bids were due 10/11/2006.
During the week of 9/25/2006:
1. Removal of all asbestos containing floor tile in the facility.
2. Removal of asbestos tile insulation from processing unit.
3. Removal of ballast, bulbs, mercury switches, and transformers from inside of the building.
On 10/10/2006, removed 3 separate sets of power lines and wires leading from a set of four transformers and another set of three transformers, all still attached to electric panels within the facility.
On 10/11/2006, OSC met with EPA Tech Specialist, EPA Region 1 TOSCA specialist, 2 VT DEC reps, and Bennington town officials in Town Hall for a discussion regarding the engineered cap of the Site. One VT DEC reps requested a cap design that was 100% water impermiable (to limit PCB migration and groundwater contamination) whereas the other rep felt it was unnecessaty since the plan calls for the removal of highly contaminated PCB soil. OSC reminded the group that groundwater was not an imminent hazard and thus not a significant concern of this removal. Thusm an earthen cover that would mitigated the potential for contact threat is the likely design with the understanding that the state of Vermont or town of Bennington would be responsible for the upkeep. Determined that EPA Tech Specialist only reviews CAP designs and thus WESTON needs to be tasked to create and provide engineer drawings for the CAP.
On 10/12/2006, OSC met with WESTON START to discuss tasking mechanism. Request for TDD for specialized labor will thus be made.
1) Remove 1-above ground storage tank, 1- below ground storage tank, 1 bag house structure, and 2-Transformers currently on concrete slab.
2) Demolition, segregation and disposal of the 120,000 square foot facility.
3) Demolition and disposal of the former drum storage containment area.
4) Removal and disposal of the former facility concrete slab contaminated with PCB’S. Excavation and disposal of PCB contaminated soils from under slab floor up to a possible depth of six (6 “+) feet.
5) Removal of the dry well located at the far north end of the former facility. Complete any miscellaneous soil excavation from around the former facility foot print and disposal of material.
6) Design and install an Earth cap across the entire former facility foot print and seed.
7) Decontamination of equipment and demobilization of all support zone areas.
Direct and coordinate with START and ERRS the ongoing removal action. In addition, coordinate efforts with VT DEC and the Town of Bennington, VT.
Town of Bennington and Vermont DEC have to agree on a maintenance agreement regarding keeping the integrity of the earthen cap of the Site.
