Respondent disclosed they shipped and disposed PCB remediation waste at a landfill in Pennsylvania which is not authorized to accept PCB waste. Original material was low concentration (94 parts per million) and was diluted to non-detectable before disposal - Region 2 is not seeking its removal from the landfill since it would be impossible to identify and separate. Respondent established an enhanced system of monitoring, marking, separating, tracking, and disposal of all future hazardous waste shipments to guard against incidents of this nature occurring in the future. Final penalty $191,884.
