Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1965. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a petroleum product bulk storage and distribution facility, with aboveground and underground tanks supplying tanker trucks from a bermed tank farm area. An underground waste oil storage tank installed as early as the mid-1960s was removed in 1990, along with 40 cubic yards of contaminated soil. Ongoing remediation includes product recovery via hand-bailing and a Petrotrap system, Dual Phase Extraction and Product/Groundwater Recovery wells, soil vapor extraction systems, and a multi-year groundwater monitoring program. Cleanup work remains active. 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 bulk plant traces to storage and distribution operations that were well established before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The scope of documented remediation — tank removal, soil excavation, dual-phase extraction, product recovery, vapor extraction, and years of monitoring — represents substantial expenditures tied directly to releases from those pre-1986 operations. Historical carriers who issued CGL policies during the facility's early decades of operation may be obligated both to reimburse past cleanup costs and to fund the remediation that continues today.

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.
