Industrial & Manufacturing cleanup site — Restorical Research
Myrtle Street Property
606 S Myrtle St, Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1917. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has supported continuous heavy industrial use since approximately 1917, when Seattle Astoria Iron Works established a machine shop, boiler room, steel-cutting operations, and a blacksmith shop on the site. Continental Can Company followed with can-making equipment manufacturing from the 1930s through 1985, and four aboveground storage tanks associated with these operations were removed in 1988. Cleanup under the Voluntary Cleanup Program included capping contaminated soil beneath asphalt pavement and buildings and implementing a restrictive covenant; post-cleanup groundwater monitoring ran from 1998 to 2000, with periodic effectiveness reviews continuing through at least 2025. The property is currently occupied by Seattle Iron & Metals, an active metals recycling facility. 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.

Heavy industrial operations at this site — machine shop work, steel cutting, can manufacturing, and aboveground fuel storage — ran from 1917 through 1985, spanning nearly seven decades before the cutoff year when occurrence-based CGL policies still carried no effective pollution exclusion in Washington. The contamination capped in place and monitored here is directly attributable to those successive pre-1986 operators and their storage infrastructure. Historical carriers who issued CGL policies to Seattle Astoria Iron Works, Continental Can Company, or other operators during that window may be obligated both to recover the remediation costs already incurred and to fund the ongoing institutional-control and periodic-review obligations that remain.

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.
