Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

The Mason County Sportsmans Association property operated as an indoor shooting range, generating lead contamination in soil at concentrations as high as 19,000 mg/kg alongside arsenic contamination in soil and groundwater above MTCA cleanup levels. Ecology has attributed the contamination to improper handling of lead wastes from range operations. No remediation has been completed at the site; the property is enrolled in the Standard Cleanup program and awaiting future cleanup action. 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.

Heavy metal contamination from shooting range operations is the product of years of accumulated deposition — not a single incident — and the lead and arsenic detected here reflect that long-term pattern. If the range operated at any point before 1986, occurrence-based Commercial General Liability policies in effect during that period carried no effective pollution exclusion in Washington and may still respond to cleanup costs today. The investigation, remedial design, and active cleanup of lead- and arsenic-impacted soil and groundwater that the property owner now faces are precisely the expenditures those historical policies were written 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.
