Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1970. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This industrial maintenance facility has been in operation since the early 1970s, serving as a storage and maintenance hub for Cenex trucks transporting fertilizer products, with service shops and a truck tank rinse-out station on site near the intersection of Highway 12 and US395 northeast of Pasco. The truck tank rinsing station was shut down in 1994, with rinsate collected in above-ground tanks as a source control measure. Groundwater monitoring for nitrate and arsenic has been conducted as part of a multi-year site assessment and monitoring project dating to at least 2000, and cleanup work is ongoing under Washington's Standard Cleanup program. 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.

Industrial maintenance and chemical-handling operations at this facility began in the early 1970s — more than a decade before 1986 — with contamination from benzene, petroleum hydrocarbons, metals, and nitrates traceable directly to those pre-1986 activities and to a leach field system in use prior to 1994. Occurrence-based Commercial General Liability policies issued to facility operators during that window carried no effective pollution exclusion under Washington law and remain enforceable today. The documented remediation trail — source control infrastructure, multi-year groundwater monitoring, and ongoing Standard Cleanup proceedings — represents expenditures 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.
