Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1970. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property operated as a mining facility under Transalta Centralia Mining LLC, with structures constructed in 1970 and industrial operations centered on heavy equipment maintenance — sandblasting, painting, and machine-shop work in areas including a Drainline Shop and machine shed. A Phase II environmental site assessment completed in December 2020 identified contamination exceeding MTCA cleanup levels in soil and groundwater adjacent to those maintenance areas. No formal cleanup has been completed to date, though some removal of contaminated soil is anticipated as the property is developed into a solid waste handling facility. 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 contamination documented here — arsenic, chromium, lead, petroleum hydrocarbons, carcinogenic PAHs, and pentachlorophenol — is consistent with long-running industrial maintenance activity that traces to structures built in 1970, more than fifteen years before occurrence-based CGL policies stopped reliably covering pollution claims. The site's multiple historical recognized environmental conditions confirm a long-standing contamination basis tied to those pre-1986 operations. The investigation, remediation design, and disposal costs the property owner now faces could plausibly be funded by historical carriers whose policies were in force during the facility's operational window.

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.
