COPCs
(What's in the tank?)
A chemical of potential concern (COPC) is a chemical found in tank waste vapors that may pose a hazard in the work environment. The COPCs for Hanford tank wastes were categorized in 2006 by evaluating the chemicals detected and hypothesized in the Hanford tank vapor space as a source for vapor hazards, as listed in the IH Technical Basis. The IH Technical basis details the approach to controlling against vapor-related hazards and references a series of Pacific Northwest National Laboratory technical documents.
