Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1951. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property served as a warehouse and distribution center for Associated Grocers beginning in 1951, with four buildings constructed in 1951–1952 including a truck repair shop and pump island supported by underground storage tanks containing gasoline, diesel, and oil. Cleanup activities have spanned decades under the Voluntary Cleanup Program: UST removals in the late 1980s and again in 2022, free product recovery via passive skimmers since 2002, and a major 2009 excavation that removed 12,000 tons of contaminated soil and 17,500 gallons of affected groundwater with 1,500 pounds of Oxygen Release Compound applied. The site is also part of the Lower Duwamish Waterway Superfund Site, with continuous monitoring and planned future remedial actions still underway. 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.

Petroleum contamination at this property originated from underground storage tanks installed in the early 1950s to fuel Associated Grocers' truck fleet — more than three decades before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion. The scale of documented remediation expenditures here is substantial: multiple rounds of tank removal, years of free product recovery, a 12,000-ton soil excavation, groundwater recovery, and ongoing monitoring across more than two decades. Historical carriers who issued CGL policies during that pre-1986 operational window may be obligated both to recover past cleanup costs and to fund the remedial work that remains ahead.

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.
