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.

Simplot Grower Solutions operates an agricultural products retail facility on approximately 3.4 acres at 7528 Postma Road in Moxee, storing fertilizers, pesticides, and soil amendments in bulk tanks and retail containers delivered by rail and truck. A 1996 underground storage tank excavation on the adjacent Moxee City Shop property documents the area's legacy of buried infrastructure, and GeoEngineers conducted multi-year monitoring at the site as early as 2013. Simplot entered Ecology's Voluntary Cleanup Program in 2014, with four additional groundwater monitoring wells recommended as the next remediation step. 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 1996 UST excavation on the adjacent Moxee City Shop property — consistent with a tank installation around 1971 under a standard 25-year lifecycle — places active underground storage infrastructure in the immediate vicinity squarely within the pre-1986 insurance window. Multi-decade bulk agrichemical storage at this address, with nitrate and sulfate contamination bearing no sign of a recent accidental release, reflects the slow, ongoing release pattern that occurrence-based CGL policies issued before 1986 were written to cover. Historical carriers who wrote policies during that operational window may still be obligated to fund the investigation and remediation costs the Simplot Moxee City facility 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.
