  • Capital Industries
  • Burlington Environmental (known as “PSC”)

Each of the four companies has completed remedial investigations under separate Orders. The draft Agreed Order contains requirements for jointly conducting a Feasibility Study and drafting a Cleanup Action Plan.

Ecology is also accepting public comment on a proposed permit modification for the Burlington Environmental (PSC Environmental Services) Georgetown facility. The Burlington Environmental facility no longer operates as a dangerous/hazardous waste treatment, storage, and disposal facility.

The current permit references an Agreed Order issued in 2010 to govern the cleanup of the eastern portion of Burlington Environmental’s Georgetown site. The proposed permit modification will additionally reference the new “West of 4th” Agreed Order, which sets out requirements for addressing the western portion of the s site.
