Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1916. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Washington Water Power Central Steam Plant was built in 1915 and operated from 1916 through 1986, producing steam and electric power — initially from coal and sawdust, then exclusively from petroleum after all boilers were converted by 1970. Seven concrete underground storage tanks, installed between 1966 and 1975, supplied petroleum to the plant's boilers; a petroleum release from those tanks was identified between 1982 and 1984. Investigations beginning in the 1980s led to the installation of mechanical remediation systems in 1997 — including hydraulic control, free product recovery, bioventing for oil biodegradation, and stormwater controls — along with significant soil excavation. Operations and monitoring at the site remain active. 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.

Petroleum contamination at this property traces directly to underground storage tanks that supplied fuel to boilers during decades of industrial operations, all of which predate 1986. Occurrence-based CGL policies issued to Washington Water Power during that operational window carried no effective pollution exclusion under Washington law and remain enforceable today. The remediation expenditures documented here — multi-year investigations, mechanical recovery systems, bioventing, soil excavation, and ongoing monitoring now spanning nearly three decades — represent costs that historical carriers may be obligated to reimburse and to continue funding.

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.
