This industrial graving dock was constructed between 1945 and 1954 on the Umpqua River estuary and operated continuously for barge maintenance — sandblasting, anti-fouling paint application, and welding — through approximately 2011. Investigations dating to 1989 confirmed metals (barium, chromium, zinc, lead), BTEX, tributyltin (TBT), and petroleum hydrocarbons in upland soil, pore water, and estuary sediment, with TBT and metals detected across multiple sediment sampling events between 2011 and 2017. Oregon DEQ's Revised Focused Feasibility Study, completed in August 2023, recommends aggregate capping as the selected remedy, but implementation has not yet begun — filling the graving dock, capping, institutional controls, deed restrictions, and a Contaminated Media Management Plan all remain ahead. That history could support an insurance coverage claim against the carriers who issued policies more than 40 years ago — coverage that could help fund the cleanup ahead.
Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Oregon — and those policies may provide coverage that remains enforceable today. 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 contamination at this property — tributyltin, heavy metals, and petroleum hydrocarbons — originated from industrial barge maintenance operations that began as early as 1945, more than four decades before 1986. The substantial remedial work still ahead — aggregate capping, dock filling, institutional controls, and long-term sediment management under active Oregon DEQ oversight — represents ongoing and future cost obligations that pre-1986 carriers may be obligated to fund going forward.
