Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1978. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

The J.H. Baxter South Woodwaste Landfill began operations in 1978 as a private disposal site for woodwaste — primarily untreated wood shavings and bark — generated at J.H. Baxter Company's adjacent wood preserving facility. The landfill was scheduled for closure in 1989, with closure activities encompassing final grading, placement of a two-foot vegetated soil cap, stormwater drainage controls, and gas control measures. Groundwater monitoring commenced in 1988 and continued through at least 2001 under a planned 20-year post-closure monitoring program, with closure costs estimated at $163,500 and annual post-closure monitoring costs of $22,400. The landfill is currently inactive. 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.

Woodwaste disposal operations at this site ran from 1978 through planned closure in 1989, spanning the full period during which occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. The contamination at issue — leachate and gas migration from the landfill's decomposing woodwaste mass — is precisely the kind of gradual, continuous release those pre-1986 policies were written to address. The groundwater monitoring obligations and closure costs the property owner faces now represent remedial expenditures that historical carriers whose policies were in force during the 1978–1986 operational window may be obligated to fund.

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.
