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 at 4739–4743 Ballard Avenue NW, operated by Kolstrand Supply, carries heavy metal and petroleum hydrocarbon contamination consistent with historical industrial use and the property's location within the Tacoma Smelter Plume King County facility — an area affected by smelter operations that ceased in 1986. A 2008 ERTS complaint identified existing contamination attributable to those historical uses, and excavation and removal of fill material was completed in 2009 under the Voluntary Cleanup Program. Groundwater monitoring for arsenic has continued at least through 2018 with further sampling still required, while historical groundwater exceedances of cadmium, chromium, and lead have since returned to compliance. 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.

The arsenic, cadmium, chromium, and lead contamination documented at this site traces to industrial operations and smelter-era fallout that predate 1986 — the year occurrence-based Commercial General Liability policies began incorporating effective pollution exclusions in Washington. Historical CGL carriers who issued policies to Kolstrand Supply or prior property operators during that pre-1986 window may remain obligated to fund the documented remediation costs, including the 2009 excavation, ongoing groundwater monitoring, and any additional remedial action the outstanding arsenic sampling may require. The property's confirmed position within the Tacoma Smelter Plume provides an unusually traceable contamination origin, tightening the evidentiary link between the pre-1986 operational period and the insurance coverage in force at the time.

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.
