Public Works cleanup site — Restorical Research
South Seattle Community College
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1969. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has served as South Seattle Community College since at least the late 1960s, with campus operations including automotive and aircraft mechanics and maintenance training supported by numerous underground storage tanks holding aviation gasoline, jet fuel, diesel, automotive gasoline, naphtha, and waste oil. In 1994, 17 USTs, hydraulic hoists, and oil/water separators were removed along with 430 cubic yards of contaminated soil, accompanied by groundwater pumping and installation of a soil venting pipe. A second phase in 2013 removed 11 additional USTs and dispenser islands, requiring tank inerting, triple rinsing, and offsite disposal of approximately 3,750 gallons of rinsate and pit water. Cleanup work is ongoing. 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 underground storage tanks at this site were installed and operated decades before 1986, during an era when occurrence-based Commercial General Liability policies routinely covered pollution events without exclusion. Two documented phases of remediation — spanning 1994 through 2013 and encompassing 28 tank removals, large-scale soil excavation, groundwater recovery, and continued site management — represent substantial cleanup expenditures tied to contamination from those pre-1986 operations. Historical carriers who issued CGL policies during that operational window may be obligated both to recover past remediation costs and to fund the cleanup work that remains.

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.
