Public Works cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1937. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has served as the Washington State Department of Transportation District 4 Headquarters and Maintenance Facility since 1937, housing vehicle and equipment maintenance, a sign shop, paint-blacksmith-carpenter shop, landscape operations, and storage of highway maintenance and construction materials. Cleanup under the Standard Cleanup program has included excavation and removal of multiple dry wells and contaminated soil — including 40 cubic yards from a hydraulic lift area installed in 1936 — disposal of contaminated soil and sludge at landfills, capping of excavated areas with asphalt or concrete slurry, in-place abandonment of dry wells with bentonite-cement slurry, bioremediation, and installation of a new stormwater collection and treatment system. Groundwater monitoring ran from 1991 through at least 1996, with additional assessments conducted in 2005–2006, and cleanup work remains 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.

Contamination at this facility traces to maintenance and industrial operations that began in the late 1930s — nearly five decades before 1986, when occurrence-based Commercial General Liability policies ceased reliably covering pollution claims. The documented remediation expenditures — soil excavation, dry well removal, bioremediation, capping, stormwater system installation, and over a decade of groundwater monitoring — were incurred to address releases tied directly to those pre-1986 operations. Historical carriers who issued CGL policies during that operational window may be obligated both to recover past cleanup costs and to fund the remediation work that continues at the site.

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.
