Farm/Agriculture cleanup site — Restorical Research
Warden City Water Supply Wells No. 4 and 5
1900 Block W 1st St, Warden, Grant County
Restorical Research
Preliminary Site-Specific Analysis

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

This property operated as a Simplot Grower Solutions (also known as Simplot Soilbuilders) agri-chemical facility from at least 1940 through 1992, serving as a retail outlet for fertilizers, pesticides, and soil amendments while providing fertilizer blending, application services, and consulting. Ethylene dibromide (EDB) — deployed at this site as a soil fumigant and as an additive for leaded gasoline, and federally banned in 1984 — is a primary contaminant of concern, with contamination confirmed in city water supply wells drilled in 1957 and 1968. Cleanup has included excavation with updated volume and soil-treatment plans, proposed ex-situ soil vapor extraction, remedial investigation and feasibility study activities with monitoring from 2011 through 2018, well decommissioning, packer installation, and the use of institutional controls and monitored natural attenuation for groundwater. 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 contamination here is explicitly documented as a remnant of historical agri-chemical operations spanning from at least 1940 through 1992 — covering the entire pre-1986 period when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion in Washington. EDB's 1984 ban confirms that the compound was in active use at this property for decades before modern pollution-exclusion language became routine, placing the contamination-causing operations squarely within those historical carriers' coverage windows. The site's documented remediation expenditures — excavation, vapor extraction, years of remedial investigation, monitoring, and ongoing groundwater controls — represent costs the historical carriers 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.
