Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property, historically known as the Signal Oil site, operated as a petroleum bulk plant engaged in the storage and distribution of petroleum products prior to 1986. Benzene and petroleum-gasoline contamination has been confirmed in soil, and cleanup is now underway under the Model Toxics Control Act, with the site enrolled in the PLIA Petroleum Technical Assistance Program. The property is currently subject to redevelopment as the Greenwood & 85th Redevelopment project. 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 petroleum-gasoline and benzene contamination at this site originated from bulk petroleum operations conducted during an era when occurrence-based Commercial General Liability policies had no effective pollution exclusion. Signal Oil's pre-1986 bulk-plant activities are the documented source of the release that now drives mandatory cleanup obligations under MTCA. Historical carriers whose CGL policies covered Signal Oil's operations during that window remain plausible candidates to fund the remediation costs the current responsible parties face going forward.

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.
