Tosco Bulk Plant 0296
Ilwaco, Pacific County

Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1930. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Tosco Bulk Plant 0296 has operated as a bulk fuel facility at 302 1st Avenue S.W. in Ilwaco since at least the 1930s, with ownership passing through Unocal (which held the site until 1992–93), Tosco Refining Company, Tetz Oil Company, and Wilcox and Flegel Oil Company. Documented cleanup work includes the removal of a 550-gallon heating oil tank in 1996, followed by multi-year groundwater monitoring from at least 2002 through 2006. As of October 2017, Phillips 66 Company has assumed responsibility for ongoing corrective action and remediation obligations at the site. 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.

Bulk fuel distribution operations at this property date to the 1930s — more than five decades before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion. The petroleum hydrocarbon contamination documented here is the direct result of that long-term bulk plant activity across a succession of operators, each of whom would have carried CGL policies during their respective tenures. The remediation obligations now managed by Phillips 66 — tank removal, groundwater monitoring, and ongoing corrective action — represent costs that historical carriers from the pre-1986 operational window may be obligated to fund.

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.
