Industrial & Manufacturing cleanup site — Restorical Research
Middle Waterway Steel Slag
Tacoma, Pierce County
Restorical Research
Preliminary Site-Specific Analysis

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

This property in Tacoma's Middle Waterway served as a steel foundry and aluminum alloy piston casting facility, with industrial operations established well before the 1980s. The site's contamination — heavy metals, polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls (PCBs) in soil and sediment — was severe enough to warrant inclusion in the Commencement Bay/Nearshore Tideflats Superfund site when it was listed on the National Priorities List in 1983. Remediation under a 1996 Consent Decree included removal of 18,500 tons of contaminated soil and 300 tons of hazardous waste, with a remedial investigation and feasibility study following in 1997. Construction of the cleanup remedy is now complete, though performance monitoring continues and mercury contamination in Area A sediment remains above cleanup levels. 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.

Steel foundry and aluminum casting operations at this waterway site were established decades before 1986, placing the facility squarely within the era when occurrence-based Commercial General Liability policies covered pollution claims without effective exclusion. The 1983 Superfund listing confirms that contamination from those foundry operations was already significant before the CGL policy landscape shifted. The remediation expenditures incurred here — large-scale soil and hazardous waste removal, sediment cleanup, and ongoing monitoring for residual mercury — represent costs that historical carriers who insured the facility during that pre-1986 window 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.
