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.
