Dr. Tom Ryan:

The facility operates on the basis of certain waste acceptance criteria. The waste coming in has to meet that criteria to be processed by the plant. The operator of the facility has to have a process in place for periodically checking the categorisation of that waste. When the EPA is on site it will often check what is coming into the facility and have it tipped up to ensure it is appropriate. On one occasion it was noted the wrong type of waste was going into the facility. A non-compliance investigation was opened on that. The process is about making sure that the acceptance procedures are improved and that only the appropriate materials are accepted on-site.
