Gas Station cleanup site — Restorical Research
Cascade Loggers Supply Inc
Chehalis, Lewis County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1968. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as Cascade Loggers Supply Inc in Chehalis, with underground storage tanks dispensing diesel, gasoline, and oil — a facility confirmed on a 1985 USGS topographic map. In May 1993 the USTs were removed and contaminated soil was excavated, though some impacted soil was left in place. Remediation has continued under the Voluntary Cleanup Program with soil recycling, institutional controls including a Restrictive Covenant, ongoing monitoring, and periodic site reviews spanning from 1993 through at least 2019, with potential biological treatment still under consideration. 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.

The underground storage tanks at Cascade Loggers Supply were likely installed around 1968 based on their removal date, and the facility's presence on a 1985 USGS map confirms it was operating throughout the period when occurrence-based CGL policies carried no effective pollution exclusion under Washington law. The diesel, oil, and gasoline contamination found in soil and groundwater traces directly to those decades of pre-1986 tank operations. More than 25 years of documented remediation costs — UST removal, excavation, long-term monitoring, institutional controls, and planned biological treatment — represent expenditures that historical carriers who covered this facility during the contamination window may be obligated both to recover and to 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.
