DEQ anticipates receiving hazardous waste permit modification application
Chemical Waste Management, known as CWM, has notified DEQ it’s seeking to modify its Arlington landfill permit to add a new disposal unit that would expand its capacity to properly dispose of hazardous waste and chemicals of emerging concern. The facility has an existing landfill unit that accepts this kind of waste and anticipates needing additional capacity.
Much of the waste would arrive in the form of contaminated soil from large-scale cleanup operations occurring at former industrial sites including Superfund sites, firefighting training centers and military sites. Contaminants would include PFAS, a component of some firefighting foams and many consumer goods.
The facility would build the landfill unit to the same hazardous waste specifications as its existing units, including a triple-lined system that protects against groundwater contamination.
When DEQ receives the permit modification application, DEQ will analyze the application to ensure it meets DEQ and EPA hazardous waste requirements and Oregon environmental laws and regulations.
As part of this process, DEQ will work with CWM to hold a public information meeting (date TBD) and request comments on the permit application. DEQ will review the comments and draft the permit modification. Once the permit modification is drafted, DEQ will hold a public hearing and request comments on the draft permit modification.
