Restorical Research
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 — and recover costs already spent.

This property operated as a hard chromium electroplating business beginning in the early 1970s, plating concave parts from wheat-farming equipment with chrome to protect them from wear. Cleanup activities have included soil excavation of up to 3,750 tons, in situ bioremediation pilot studies using dextrose and nutrient injections with groundwater recirculation, and the abandonment and replacement of two drinking water wells. Long-term site management involves an environmental covenant, containment of residual contaminated soil beneath a concrete cap, and ongoing stormwater controls. 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.

Chromium contamination at this site traces directly to electroplating operations that began in the early 1970s — more than a decade before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. The documented remediation expenditures here — thousands of tons of excavated soil, replacement drinking water wells, bioremediation pilot work, and a long-term environmental covenant — are all tied to those pre-1986 industrial operations. Historical carriers who issued CGL policies to the electroplating business during that window may remain obligated to fund both the cleanup costs already incurred and the long-term management work still under way.

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.
