Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1980. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

The Electrofinishing Company operated an electroplating facility at this Auburn property from the early 1980s through 1989, with industrial processes involving cyanide, acids, corrosives, and electroplating solutions. On-site treatment consisted of cyanide destruction and neutralization of spent electroplating solutions, but improper storage and management of solvents, acids, and other corrosives resulted in soil contamination that was identified in 1989. The site was added to Washington State's Contaminated Sites List in 1990, and 23 cubic yards of contaminated soil have been identified as requiring excavation; no active cleanup has yet commenced. 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.

Electroplating operations at this property began in the early 1980s and ran through 1989, spanning the years when occurrence-based Commercial General Liability policies had no effective pollution exclusion under Washington law. The contamination here — metals, cyanide, and halogenated organic compounds deposited through years of improper chemical handling — is the type of chronic industrial release that pre-1986 CGL policies were written to address. With remediation costs still ahead and 23 cubic yards of impacted soil yet to be excavated, historical carriers who issued policies during this facility's operating years may be obligated to fund the cleanup.

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.
