The project would replace the joint sealant (caulking) located on the exterior walls of the Fred Johnson Building at the Celilo Converter Station facility in The Dalles, Oregon. The sealant between the precast stone panels, masonry columns, windows, and metal louvers would be removed and replaced. The existing sealant has been tested and determined to contain elevated levels of polychlorinated biphenyl, which would require abatement, and disposal at an approved landfill.
