Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1956. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Graphic Packaging International's facility at 601 Monster Rd SW has operated as an active industrial site since approximately 1956, with folding carton manufacturing and printing operations anchoring its long commercial tenure. The property housed a former Oil Water Separator, a Waste Solvent Vault that operated from 1979 to 1984, and a waste collection vault — subgrade infrastructure consistent with decades of industrial activity. Cleanup activities beginning in the late 1980s have included excavation and off-site disposal of at least 678 tons and 165 cubic yards of impacted soil, removal of all three subgrade features, periodic free-product recovery from groundwater monitoring wells, and injection of approximately 165 pounds of oxygen-release compound to support enhanced biodegradation. Remediation is 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.

Industrial operations at this property began in 1956 — thirty years before the post-1986 pollution exclusions that rendered most CGL policies unavailable for contamination claims. The waste solvents managed in an on-site vault and the free product recovered from groundwater are precisely the slow, ongoing releases that occurrence-based pre-1986 CGL policies were written to cover. The documented remediation costs here — large-scale soil excavation, subgrade structure removal, free-product recovery, and active biodegradation treatment — represent expenditures that historical carriers 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.
