Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1961. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

General Electric Company operated an industrial apparatus service shop at this Spokane Valley property from 1961 to 1980, repairing transformers and other industrial and utility equipment — with polychlorinated biphenyls (PCBs) from transformer oils constituting the principal contamination left behind. Remediation has included demolition and excavation of buildings, tanks, dry wells, and contaminated soils, along with soil vitrification or off-site disposal and incineration, deep soil grouting, and long-term groundwater monitoring with institutional controls. Original vitrification costs were estimated at $4.9 million; a proposed shift of a portion of the impacted soils to off-site disposal and incineration was projected to cost an additional $3.5 million. Construction is complete and performance monitoring is ongoing. 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 PCB contamination at this property traces directly to transformer-repair operations that GE conducted from 1961 through 1980 — spanning more than two decades during which occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. Contamination was first identified in an October 1985 site inspection, placing its discovery squarely within the coverage window of pre-1986 policies that were in force during GE's operational tenure here. The remediation expenditures documented at this site — excavation, vitrification, incineration, deep grouting, and long-term monitoring with institutional controls, totaling millions of dollars — represent costs that historical carriers who issued CGL policies to GE during that period may still 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.
