 The EPA approved the "dry-tomb" PCB landfill which failed from the beginning because it was capped with nearly a million gallons of water in it.The site never operated as a commercial facility because residents forced the Governor to include in the deed that it was a one-time only toxic waste facility.The landfill was built with plastic liners, a clay cap, and PVC pipes which allowed for methane and toxic gas to be released from the landfill.
