Landfill cleanup site — Restorical Research
Marshall Landfill
Andrus & Spotted Rd, Marshall, Spokane County

Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1950. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Marshall Landfill encompasses four historic land use areas — the approximate 25-acre Main Landfill, the Five-Acre Landfill, a gravel pit, and the Former Spokane County Landfill — with waste disposal operations documented from the 1950s through 1990. The site received solid waste, demolition debris, and hazardous materials including jet fuel, with jet fuel disposal specifically documented from 1975 through 1983. Cleanup measures have included daily sand covers during operations, installation of a passive landfill gas venting system and compacted cap at the Five-Acre Landfill in 1990, and buttress berm construction. Groundwater monitoring ran from 1989 to 2017 and landfill gas monitoring from 2015 to 2017, with remediation work continuing under the Standard Cleanup program. 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.

Disposal of solid waste, demolition debris, and hazardous materials including jet fuel began at this property in the 1950s — more than three decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and pollution exclusions had not yet been broadly enforced. The contamination now driving decades of groundwater and landfill gas monitoring traces directly to those pre-1986 disposal activities. Historical carriers who issued CGL policies to the operators or owners of this property during that operational window may be obligated to contribute to the documented and ongoing remediation costs.

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.
