Site cleanup efforts within Massachusetts over the past three years have relied more on remediation waste processing facilities outside the Commonwealth. According to filings with the MassDEP from 2011 to 2013 the proportion of shipments going outside Massachusetts went from 39% to 47%.
The proportion of constituents and contaminants processed out-of-state increased for all categories except PCBs and VOCs.
Looking at a sampling of soil-based remediation waste that was electronically attested and quantified by the receiving facility, 63% of submissions, a significant difference in quantity is observed between 2012 and 2013. In 2012 230,000 tons of contaminated soil was processed in MA while a little over 200,000 tons was processed outside MA. In 2013, soil processed in MA dropped to 137,000 tons while it increased to 230,000 tons outside MA.
What factors are influencing these trends? Regulations? Economics?
Are these trends continuing? What role do LSPs, transporters, processing facilities and PRPs play?
