Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1940. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The area south of Sunset Highway in Cashmere operated as a lumber mill from the 1940s through the late 1970s, producing lumber for fruit boxes and generating significant wood waste throughout that period. Contamination attributed to mill operations includes wood waste fill, petroleum hydrocarbons from lubrication oils, and metals in soil and groundwater. Remedial activities under the Voluntary Cleanup Program have included excavation of approximately 2,400 bank cubic yards of wood waste and 1,600 bank cubic yards of overburden soil, with ongoing site characterization, groundwater monitoring, periodic reviews, and institutional controls in place. Cleanup work is ongoing. 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 petroleum, metals, and wood waste contamination documented at this property originated from mill operations conducted over three to four decades before 1986 — the era when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. The remediation scope already undertaken — thousands of cubic yards of contaminated soil removed, groundwater monitoring programs, and institutional controls — represents documented expenditures tied directly to those pre-1986 operations. Historical carriers who issued CGL policies to the mill operators during that window may be obligated to recover past cleanup costs, with ongoing remediation creating continued exposure for future recovery as well.

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.
