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 a truck leasing facility under Rollins Leasing Corp. before transitioning to Penske Truck Leasing. A release from underground storage tanks was documented in September 1988, and four USTs were subsequently removed from the site on January 16, 1991. Petroleum hydrocarbons — both diesel and other petroleum products — have been confirmed in groundwater beneath the property. Cleanup is underway under Washington's Standard Cleanup program. 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 already leaking by 1988 and at end-of-life when removed in 1991, indicating installation likely occurred in the 1970s or earlier — well within the era of occurrence-based CGL policies that carried no effective pollution exclusion. The confirmed petroleum contamination in groundwater traces directly to those pre-1986 tank operations. As cleanup costs continue to accrue under an active remediation program, historical carriers who insured the facility during the period of tank operation may bear responsibility for both the costs already incurred and those still 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.
