Industrial & Manufacturing cleanup site — Restorical Research

Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1948. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property served as the base for Hurlen Construction Company's marine construction operations from the late 1940s through the early 2000s, encompassing pile driving, dredging, general marine construction, and storage and operation of cranes, barges, and other heavy equipment. Documented discharges include a used oil release in 1970 and a petroleum release in 1984. Cleanup activities within the Lower Duwamish Waterway and upland areas have included sediment and soil excavation, groundwater monitoring, stormwater management, and extensive source control measures — a long-term, multi-faceted remediation effort that remains 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.

Marine construction and heavy-equipment operations at this site began more than three decades before 1986, and the documented oil and petroleum discharges in 1970 and 1984 fall squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The remediation costs already incurred — sediment removal, soil excavation, groundwater monitoring, and years of source control — along with the costs still ahead as cleanup continues, represent expenditures that historical carriers who insured these operations may be obligated both to reimburse 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.
