Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This site was the location of a Peninsula Light Company voltage regulator containing PCB-laden mineral oil — a transformer that, given the 1979 federal ban on PCB manufacture, was produced and installed no later than the late 1970s. On January 24, 2004, the transformer ruptured, releasing approximately 60 gallons of PCB-containing oil into the surrounding environment. Subsequent investigation confirmed PCB contamination in groundwater at the property; the site is currently awaiting cleanup under the 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 transformer at this property was manufactured and installed before the 1979 PCB ban, placing its operational origins well within the pre-1986 window when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The PCB contamination now confirmed in groundwater traces directly to equipment that was in service during that earlier coverage period. Investigation and remediation costs the property faces — still ahead, with cleanup not yet commenced — could plausibly fall within the scope of historical CGL policies issued to the operators during the years the PCB-containing transformer was in active use.

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.
