This industrial property has hosted heavy manufacturing since the 1920s, beginning with a steelworks foundry and plate shop that operated with earthen floors and oil-fueled boilers, followed by multiple industrial tenants from 1950 onward. Underground storage tanks for diesel and gasoline were installed before 1986 and removed in 1993, and while the associated 1995 UST release received a No Further Action determination, broader contamination persists — diesel concentrations up to 298 mg/L and PAHs have been confirmed in groundwater, and stormwater from the site drains to the Willamette River through Outfall 19. The property entered Oregon DEQ's Voluntary Cleanup Program in 2016, and an active stormwater source control evaluation is underway as part of the Portland Harbor Joint Source Control Strategy, with a revised workplan submitted in October 2025. 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 — diesel-range petroleum hydrocarbons and PAHs in groundwater, plus a stormwater pathway discharging to the Willamette River — traces to decades of heavy industrial use that began with a steelworks foundry in the 1920s and continued through multiple industrial operators and underground storage tank installations, all well before 1986. The ongoing stormwater source control evaluation under the Portland Harbor Joint Source Control Strategy, continued investigation through Oregon DEQ's Voluntary Cleanup Program, and any remediation ultimately required to address the groundwater and stormwater impacts represent future cost obligations that historical pre-1986 carriers may be obligated to fund.
Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.
