Gas Station cleanup site — Restorical Research
Conconully General Store
Conconully, Okanogan County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1946. 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 gas station and general store since at least 1946. Two steel underground storage tanks installed in 1974 remained in service until 1995, when they were upgraded with new tanks; during that replacement work, petroleum contamination was discovered in the surrounding soils. Cleanup under the Standard Cleanup program has included removal and disposal of the two original USTs, excavation of 152 cubic yards of petroleum-contaminated soil hauled offsite for aeration, backfilling and asphalt capping of the excavation, and long-term monitoring of the stockpiled soil. 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.

Gas station operations at this property date to 1946 — four decades before occurrence-based Commercial General Liability policies gave way to claims-made forms with pollution exclusions in 1986. The petroleum release discovered in 1995 is tied directly to underground storage infrastructure that served those pre-1986 operations, and the documented remediation costs — tank removal, soil excavation, offsite treatment, and ongoing monitoring — are the type of cleanup expenditures that historical CGL 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.
