Industrial & Manufacturing cleanup site — Restorical Research
Dioxin Release at Mill St & N Railroad Ave

Restorical Research
Preliminary Site-Specific Analysis

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

This parcel is the off-property portion of the former Pacific Wood Treating facility, defined by a boundary established to capture dioxin contamination in soil that extends beyond the main facility footprint. A dioxin exceedance was confirmed in soil at this location, and the site is currently awaiting cleanup with no active remediation work commenced. The contamination source is the historical wood treating operations of the adjacent former Pacific Wood Treating Co. site. 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.

Dioxin contamination of this type is a hallmark of wood treating chemicals — particularly pentachlorophenol — that were in routine industrial use well before 1986, when occurrence-based Commercial General Liability policies contained no effective pollution exclusion. Because this parcel's dioxin burden traces directly to the former Pacific Wood Treating facility's pre-1986 operations, CGL policies issued to that operator during the applicable window may still be enforceable to fund the site investigation, cleanup design, and remediation work that lies ahead.

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.
