Gas Station cleanup site — Restorical Research
Olive Crest
Tacoma, Pierce County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1921. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This Tacoma property operated as a gasoline service station from 1921 through the mid-1960s, with two underground storage tanks — one 2,000 gallons and one 3,000 gallons — holding gasoline and petroleum products throughout that period. In July 2018, those relic USTs were excavated and removed along with 93.29 tons of petroleum-contaminated soil; the area was backfilled with crushed rock and pea gravel and the surface restored with new asphalt. Diesel-range and motor oil-range hydrocarbons remain detected in site groundwater above cleanup levels, and 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 — petroleum hydrocarbons, benzene, and lead — traces directly to gasoline storage and dispensing operations conducted from 1921 through the mid-1960s, entirely within the era of occurrence-based Commercial General Liability policies that carried no effective pollution exclusion. Lead detected inside the removed USTs is physical evidence of leaded gasoline dispensed during that pre-1986 window, corroborating the contamination timeline. Remediation expenditures already incurred — UST removal, soil excavation, site restoration — and costs still ahead to address groundwater exceedances are the type of losses that historical carriers active during those decades of operation 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.
