Public Works cleanup site — Restorical Research
520 Pontoon Construction Site
Aberdeen, Grays Harbor County
Restorical Research
Preliminary Site-Specific Analysis

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

This property served as the SR 520 Pontoon Casting Project construction facility in Aberdeen, managed by the Washington State Department of Transportation. During site closure, WSDOT personnel observed PCP-treated light poles that appeared to be leaching pentachlorophenol into surrounding soils. Site investigation has been conducted, with drill cuttings from soil borings contained in a 55-gallon drum; no active remediation beyond that containment measure has been reported to date. 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 site originates from pentachlorophenol-treated wood poles installed as part of a public infrastructure project — materials whose use was significantly restricted and phased out for most new applications before 1986 due to environmental and health concerns. Occurrence-based Commercial General Liability policies issued during that pre-1986 window carried no effective pollution exclusion and remain potentially enforceable against historical carriers. The ongoing leaching from these poles establishes a release directly traceable to pre-1986 materials, giving WSDOT or associated responsible parties a plausible basis to access those historical policies to fund investigation and cleanup costs.

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.
