Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1931. 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 combination log sort yard and sawmill, with aerial photographs confirming industrial activity as early as 1931 and on-site facilities including a machine shop, fueling area, and dip tank area. Slag fill was used across the yard until 1981, and environmental investigations beginning in the 1980s revealed extensive layers of wood waste and slag throughout the soil. Remediation under the Voluntary Cleanup Program has included source control, demolition of site structures, soil excavation, installation of groundwater monitoring wells, and construction of a 29.4-acre roller-compacted concrete cap. Cleanup work is ongoing, with soil testing conducted as recently as 2014. 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.

Industrial operations at this property date to at least 1931 — more than five decades before 1986, when occurrence-based Commercial General Liability policies still provided broad pollution coverage with no effective exclusion in Washington. The contamination requiring remediation here originated entirely from decades of slag disposal and log yard operations conducted within that pre-1986 window, with slag use ceasing in 1981. The documented cleanup expenditures — demolition, soil excavation, groundwater monitoring, and construction of a nearly 30-acre concrete cap — represent costs that historical carriers who issued CGL policies during those operational decades may be obligated both to recover and to fund going forward.

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.
