Landfill cleanup site — Restorical Research
Mica Landfill
Hidden Hollow Dr, Mica, Spokane County

Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1972. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

The Mica Landfill operated as a solid waste disposal facility from 1972 through 1990 under Spokane County, and jointly with the City of Spokane through 1991, accepting approximately 65,000 tons per year of residential and municipal solid waste, dewatered sewage treatment plant sludge, demolition debris, and industrial wastes. Groundwater monitoring began in 1983, contamination was confirmed, and the site was placed on the National Priorities List in 1985. A comprehensive remedial investigation and feasibility study ran from 1988 through 1992, followed by an interim action from 1992 to 1994 that included landfill capping and the installation of leachate, stormwater, and gas collection and treatment systems. The site remains under active operation and maintenance, with ongoing institutional controls, groundwater monitoring, site security, and five-year reviews of cleanup actions. 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.

Landfill operations here began in 1972 and contamination was already confirmed and on the regulatory record by 1985 — entirely within the window when occurrence-based Commercial General Liability policies were standard and lacked enforceable pollution exclusions. The operators at the time — Spokane County and the City of Spokane — carried institutional insurance during those pre-1986 years, and the slow, continuous leachate migration and groundwater impacts documented at this site are precisely the type of occurrence those policies were written to cover. Decades of documented expenditures on cap construction, collection systems, and long-term monitoring represent costs that historical carriers may still 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.
