Bulk Plant cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1971. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Olympic Pipeline Company Castle Rock Pump Station was constructed in 1971 as part of a fuel distribution system completed in 1965, moving gasoline and diesel through underground piping and pumps. A leaking pump drain line was observed in 1987, and in May 1997 a pump seal failure released approximately 1,090 gallons of fuel — primarily gasoline with some diesel — at the site. Cleanup activities have included excavation of impacted soil, installation and operation of groundwater treatment systems including multi-phase extraction (MPE) and sulfate injection, ongoing shallow groundwater capture and disposal, soil treatment, well abandonment, and multi-year monitoring and reporting. Remediation remains in progress. 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.

OPLC's pump station has operated since 1971, meaning the company carried CGL policies at this facility for more than fifteen years before 1986 — policies written for fuel distribution operations of this era that had not yet incorporated effective pollution exclusions. The contamination here is directly traceable to the fuel distribution infrastructure installed and operated during that pre-1986 window, giving those historical carriers a concrete connection to the releases documented at this site. The remediation expenditures already on record — excavations, piping reconstruction, groundwater treatment systems, long-term capture and monitoring programs — represent costs already incurred and work still underway; carriers whose policies covered OPLC's operations at this pump station before 1986 may be obligated both to recover 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.
