Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1936. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

Two service stations operated on this Renton property beginning as early as 1936 and 1937, with the northeastern parcel at 902 S 2nd St documented as a service station from 1937 to at least 1968. Regulatory records identify four underground storage tanks at the site — a 6,000-gallon, a 5,000-gallon, a 2,000-gallon, and a 1,000-gallon tank — along with physical evidence of a backfilled pit consistent with a prior tank removal. An intrusive soil investigation has confirmed TPH-G and 1,2-Dibromoethane (EDB) contamination in soil; no active cleanup work has yet commenced. 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.

Gasoline operations at this property date to 1936, and the detection of EDB — a leaded-gasoline additive phased out before 1986 — provides definitive chemical evidence tying the contamination to pre-1986 fueling activity. Occurrence-based CGL policies issued to the service station operators across that decades-long window had no effective pollution exclusion in Washington and remain enforceable today. The investigation, tank-related remediation, and soil cleanup costs that now lie ahead for this property represent expenditures that historical carriers whose policies covered those pre-1986 operations may be obligated to fund.

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.
