This Auburn property operated as a wood treatment facility under the name Tyee Cedar and Lumber (formerly Tyee Lumber and Manufacturing) from 1957 to 1969, during which wood gutters were dipped in a 5% pentachlorophenol solution for wood preservation. The site subsequently operated as a lumber yard from 1974 onward and has been listed on Ecology's Contaminated Sites List since October 1984. Cleanup activities have included the removal of two underground storage tanks in the early 1990s and the relocation of pentachlorophenol dip tanks; no active remediation of the soil contamination has yet commenced. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Washington. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.
The pentachlorophenol contamination at this property traces directly to wood treatment operations conducted between 1957 and 1969 — more than a decade before 1986, when occurrence-based Commercial General Liability policies still lacked effective pollution exclusions in Washington. Carriers who issued CGL policies to the wood treatment operator during that window may be obligated to fund the investigation, remedial design, and cleanup costs the property now faces. With the site still awaiting active remediation after more than four decades on Ecology's Contaminated Sites List, the recovery opportunity against those historical policies remains open.
