Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1973. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as an industrial manufacturing facility producing plastic buoys and fenders for watercraft, with a 2,500-gallon single-wall steel underground storage tank supplying di-2-ethylhexyl adipate — a plasticizer piped directly to the manufacturing floor. The UST was excavated and removed in March 1998, at which time groundwater contamination was detected in the excavation water. Despite the tank removal, the site remained on Ecology's Hazardous Sites List as of April 2013, indicating unresolved contamination requiring further action under the Standard Cleanup program. 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 at this property traces to an industrial process tank whose single-wall steel construction and long service life place its installation decades before 1986, squarely within the era of occurrence-based Commercial General Liability coverage with no effective pollution exclusion. Cleanup costs here — UST removal, groundwater investigation, and the remediation still required to clear the Hazardous Sites List — stem directly from releases tied to those pre-1986 manufacturing operations. Historical carriers who covered the facility during that operational window may be obligated both to recover past remediation expenditures and to fund the cleanup work that remains.

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.
