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 served as the location of Aurora Crane Corporation's heavy equipment maintenance operations, where heavy oil washwater from routine crane servicing was discharged to the surface along the southern edge of the site. Contamination was identified during a 1990 inspection, revealing petroleum-contaminated soil extending to approximately five feet in depth. Remediation included the excavation of an estimated 200 to 203 tons of petroleum-contaminated soil transported off-site for bioremediation and landfarming, installation of a geotextile barrier along the southern property boundary, and backfilling of the excavation area. Cleanup under the Standard Cleanup program is ongoing. 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 petroleum contamination here originated from Aurora Crane Corporation's ongoing equipment-maintenance activities — routine industrial operations whose washwater discharges occurred well before 1986, when occurrence-based Commercial General Liability policies remained the industry standard and carried no effective pollution exclusion in Washington. Carriers who issued CGL policies to Aurora Crane Corporation or Washington Marine Engineering Corp during that pre-1986 operational window may remain obligated to address the resulting cleanup liability. The documented remediation costs — soil excavation, off-site bioremediation and landfarming, engineered barriers — represent expenditures those historical policies may be required both to recover and to fund as the cleanup continues.

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.
