Farm/Agriculture cleanup site — Restorical Research
WA WSU Research Pesticide Storage Bldg
Wenatchee, Chelan County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a farm and agricultural operation going back to 1938. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Old Research Pesticide Storage Building at Washington State University's Tree Fruit Research Center in Wenatchee was used for agricultural chemical storage and mixing from 1938 through 1995, when chemicals were transferred to a new pesticide storage facility. Contamination attributable to that historic chemical use — including the pesticides DDT and DDE as well as heavy metals — has been detected at the site. A Site Hazard Assessment scoring the site's contamination potential has been completed, though active remediation has not yet commenced. 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.

Agricultural chemical storage and mixing operations at this property began nearly five decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion. The DDT, DDE, and heavy metal contamination found here reflects the slow, cumulative release characteristic of routine chemical handling — exactly the type of ongoing environmental damage those pre-1986 policies were written to address. Historical carriers who issued CGL policies to WSU or the Tree Fruit Research Center's operators during that pre-1986 window may be obligated to fund the investigation and remediation costs this site now faces.

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.
