Preliminary Site-Specific Analysis

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

This Division Street property in Quincy served as a fumigant storage facility operated by Cenex Supply & Marketing Inc., an agricultural cooperative, with 1,2-Dichloropropane and 1,2,3-Trichloropropane identified as the primary contaminants in soil and groundwater by a Remedial Investigation completed in October 1997. Remediation has included active soil vapor extraction for soil, SVE/Microsparge treatment for groundwater, and engineered containment consisting of an impermeable asphalt cap and perimeter fence, all supported by a dedicated on-site remediation building. Construction is complete, and the site is in long-term performance monitoring with groundwater monitoring records spanning from 2001 through at least 2022. 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 fumigant contamination documented here — 1,2-Dichloropropane and 1,2,3-Trichloropropane from an agricultural cooperative's storage and rinsate operations — reflects releases that the 1997 Remedial Investigation found to be widespread and persistent, strongly indicating the contamination originated during the pre-1986 period when occurrence-based CGL policies carried no effective pollution exclusion. A cleanup covenant extending through 2025, combined with decades of vapor extraction, groundwater treatment, and engineered containment, represents substantial ongoing liability traceable to those historical operations. Historical carriers who issued CGL policies during the pre-1986 operational window may remain obligated to fund both the costs already incurred and the monitoring expenditures still accumulating.

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.
