Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1933. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a bulk petroleum facility for approximately 90 years, with operations dating to roughly 1933. An April 2022 diesel release produced a sheen on the South Fork Palouse River and prompted enrollment in the Voluntary Cleanup Program, but remedial work has addressed both the 2022 diesel spill (Phase I) and historical petroleum-contaminated soils from decades of prior operations (Phase II). Groundwater monitoring has confirmed diesel-range and oil-range petroleum hydrocarbons above MTCA Method A cleanup levels, and vapor intrusion testing detected benzene and naphthalene above Method B screening levels in indoor air at an adjacent building. 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.

Bulk petroleum operations at this site began roughly 1933 — more than five decades before 1986 — and the historical gasoline and BTEX contamination in soil is distinct from the recent diesel release. Occurrence-based CGL policies issued to operators during that extended pre-1986 window would have covered the gradual releases that produced the legacy contamination now requiring excavation, groundwater monitoring, and vapor intrusion assessment. With cleanup underway and remediation costs still accruing, historical carriers whose policies were in force during decades of petroleum operations may be obligated both to recover past expenditures and to fund the ongoing work.

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.
