Gas Station cleanup site — Restorical Research
CSSL Properties LLC
Tacoma, Pierce County

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1923. 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 1923 to 1978, with petroleum tank systems in use throughout that 55-year period. Investigations have confirmed petroleum hydrocarbon contamination — gasoline-range organics, toluene, ethylbenzene, xylenes, and naphthalene — in the site's soil; groundwater is not considered a medium of concern. The current property owner is planning an independent remedial action centered on the installation and operation of a soil vapor extraction system, a multi-year effort to address the residual contamination. 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.

Every year of active gas station operations at this property — from 1923 through the facility's closure in 1978 — falls entirely within the era when occurrence-based Commercial General Liability policies covered pollution events without effective exclusions. The soil contamination identified here is directly attributed to those historical tank-system releases, not to any recent incident. The planned soil vapor extraction system and the long-term monitoring it will require represent costs that historical carriers who issued CGL policies across those five-plus decades of operations may be obligated both to recover and to fund going forward.

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.
