Landfill cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1961. 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 construction-fill landfill from 1961 through 1991, receiving undocumented fill from various construction locations over three decades as part of Mr. Martin's excavation business. The deposited material included a wide range of debris — bricks, concrete, asphalt, wood, metal, and assorted building materials — resulting in petroleum hydrocarbon and carcinogenic polycyclic aromatic hydrocarbon (cPAH) contamination in soil and groundwater. An independent remedial action was completed on Parcel D in 2001, with groundwater monitoring conducted through 2004 and a restrictive covenant anticipated for that parcel; potential contamination from historic landfilling on Parcels A and C remains an active concern. 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.

Contamination at this site traces to landfill operations that began in 1961 and continued for thirty years under a single excavation business — well within the period when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion in Washington. The petroleum and cPAH contamination characteristic of decades of undocumented construction fill represents the type of slow, diffuse, long-running release those pre-1986 policies were written to address. Documented remediation expenditures — the 2001 remedial action on Parcel D, extended groundwater monitoring, and anticipated restrictive covenants — represent costs the historical carriers who insured the excavation business during those decades may be obligated to recover and 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.
