Bulk Plant cleanup site — Restorical Research
UNOCAL 76
Yakima, Yakima County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1950. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a petroleum bulk plant since the 1950s, originally built as a UNOCAL/76 bulk fuel distributing plant before being sold to Tosco Distributing Company. Site infrastructure includes an above-ground storage tank farm, a pumping station, two dispensers, a loading rack, and two unloading racks — the full footprint of a regional fuel distribution terminal. Active remediation under the Voluntary Cleanup Program includes Petrofix™ in-situ groundwater injections completed in November 2020, passive LNAPL collection via oil sorbent socks in 2021, and ongoing groundwater monitoring. 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.

UNOCAL held and operated this bulk fuel terminal for the decades spanning the 1950s through at least the 1980s — the precise window when the subsurface spill documented here would have occurred and begun migrating. CGL policies UNOCAL carried as the original operator are the most direct source of coverage for the contamination now driving remediation costs under Tosco's stewardship. In-situ treatment, LNAPL recovery, investigation-derived waste disposal, and multi-year monitoring are all expenditures tied to a release that originated on UNOCAL's operational watch, and historical carriers from that era may be obligated to fund both past and ongoing cleanup costs.

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.
