Preliminary Site-Specific Analysis

This property has a documented history as a property with a heating oil tank going back to 1968. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

The Corvid Construction property at 6332 6th Ave S carries contamination that migrated from the adjacent Emerald Tool facility — also known as And-All Electro Chrome, Inc. — which operated as an electroplating and manufacturing plant from approximately 1968 until it shut down in 1985. Sampling conducted in 1985 confirmed trichloroethylene (TCE), tetrachloroethylene (PCE), and metals beneath the subject property, consistent with those industrial operations next door. A 300-gallon heating oil underground storage tank on the subject property was removed in 2000 and reportedly never leaked. No active cleanup work has commenced at this site. 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 TCE, PCE, and metals beneath this property were deposited by Emerald Tool's electroplating and chrome-finishing processes across a seventeen-year window — 1968 to 1985 — that ended the year the facility closed. CGL policies issued to Emerald Tool's operators during that deposition window may carry obligations to fund the investigation and remediation costs now falling on the adjacent property. Because contamination crossed a property boundary, historical carriers for the source operator may face exposure to cleanup liability extending beyond the original facility footprint.

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.
