Industrial & Manufacturing cleanup site — Restorical Research
Tom Thumb Mine Complex Trevitt Mine
Republic, Ferry County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1908. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

The Trevitt Mine, part of the Tom Thumb Mine Complex in Republic, Ferry County, operated intermittently from 1908 through 1981 under a succession of owners including New Republic Mining Co. (1908–1910), Midget Gold Mining & Milling Co. (1909–1918), Aurum Mining Co. leased to C.M. Trevitt (1939–1950), and Day Mines, Inc., later acquired by Hecla Mining Co. (1951–1981). The mine is now inactive, with site features including two waste rock piles and three adits. An initial investigation identified elevated contaminant concentrations associated with the waste rock, but no cleanup or remediation activities have been undertaken to date. 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.

Mining operations at this site span more than seven decades before 1986, the year occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. The contamination identified at the Trevitt Mine traces directly to those decades of mining activity — waste rock disposal and associated releases that occurred while pre-1986 CGL policies were in force. The remediation costs the property now faces — site characterization, cleanup design, and eventual remediation of mine waste — could plausibly be funded by historical carriers whose occurrence-based policies covered the operators during the mine's active life.

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.
