Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1969. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

Boyer Towing, a family-owned freight and marine towing operation incorporated in 1959, has operated from this South Seattle terminal since 1969, when it began common-carriage freight service between the site and Southeast Alaska. The company acquired the terminal parcels in 1982 and 1983 and expanded operations through its subsidiary Boyer Alaska Barge Line, incorporated in 1975. Polychlorinated biphenyls (PCBs) and dioxins/furans have been confirmed above cleanup levels in sediment at the site, with both contaminants also suspected in groundwater. The property is in the Standard Cleanup program and awaiting remediation. 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.

Freight terminal operations at this property date to 1969 — more than fifteen years before occurrence-based Commercial General Liability policies ceased to be the industry standard in 1986. The confirmed PCB and dioxin/furan contamination in sediment and suspected groundwater impacts represent cleanup liabilities whose investigation, design, and remediation costs have yet to be incurred. Historical CGL carriers whose policies were in force during the terminal's pre-1986 operating decades may bear obligations to fund that upcoming cleanup work.

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.
