Farm/Agriculture cleanup site — Restorical Research
Sprague Pest Control
Spokane, Spokane County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a farm and agricultural operation predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property served as an operating base for Sprague Pest Control, with site use centered on the storage of equipment and various containers of pesticide products. Past handling of pesticides at the facility resulted in soil contamination from the insecticides chlordane and heptachlor — both chemicals whose widespread use predates their mid-1980s regulatory restrictions. The site is enrolled in Washington's Voluntary Cleanup Program; as of the most recent assessment, no active remediation had yet been undertaken. 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 chlordane and heptachlor contamination at this property traces to pesticide handling operations that occurred well before 1986, during the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The site now faces investigation and remediation costs under the Voluntary Cleanup Program — expenses that could plausibly be funded by historical carriers whose CGL policies were in force when the contamination-causing operations took place.

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.
