Industrial & Manufacturing cleanup site — Restorical Research
Carnation Dairy Seattle
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as the Carnation Dairy facility, housing a main dairy processing plant, truck wash-down area, and vehicle maintenance building supported by an internal fueling infrastructure of four underground storage tanks totaling 17,500 gallons of gasoline, fuel oil, and waste oil. Cleanup activities from 1989 through January 1991 included removal of all four USTs, excavation and off-site disposal of 160 cubic yards of contaminated soil, dewatering of the excavation pit, demolition of a concrete pad, and abandonment of five groundwater monitoring wells. Laboratory analysis of soil samples confirmed the presence of Ethylene Dibromide (EDB), a lead-scavenger additive in leaded gasoline phased out before 1986, tying the contamination directly to the facility's historical fueling operations. 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.

The petroleum contamination at this site originated from underground storage tanks that stored gasoline, fuel oil, and waste oil during industrial dairy operations predating 1986 — the period when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The detection of EDB, a chemical marker of pre-1986 leaded gasoline, confirms that the releases occurred squarely within the CGL coverage window. Documented remediation expenditures — tank removals, large-scale soil excavation, dewatering, and monitoring-well infrastructure — represent costs that historical carriers who insured the dairy's operations may be obligated both to reimburse and to fund as cleanup continues.

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.
