Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1978. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

Red Dot Corporation operated a manufacturing plant at this Tukwila property from 1978 to 2023, with industrial parts cleaning performed using a trichloroethylene (TCE) vapor degreaser located on the north side of the building. The property's building dates to 1974 and was previously occupied by Owens Corning for insulation manufacturing. A TCE vapor degreaser and two underground storage tanks (7,500 and 2,000 gallons) were decommissioned in 1996; chlorinated volatile organic compounds tracing to the former degreaser remain in groundwater. Remediation has included an in-situ enhanced amendment injection campaign completed in March 2022, with a second campaign planned for Summer/Fall 2025, alongside ongoing quarterly groundwater monitoring. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.

Why Historical Insurance Policies May Be Accessible

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.

TCE vapor degreasing operations at this property began in 1978, eight years before 1986, when occurrence-based Commercial General Liability policies were still issued without effective pollution exclusions. The chlorinated solvent contamination documented in groundwater here is the product of continuous industrial degreasing conducted throughout that pre-1986 window, precisely the type of ongoing release those policies were written to cover. With a second remediation injection campaign still forthcoming and long-term monitoring underway, the remediation expenditures are both documented and unresolved — making the historical carrier window a plausible avenue for cost recovery.

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.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
