Heating Oil Tank cleanup site — Restorical Research
Old Pierce County Court House
Tacoma, Pierce County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a property with a heating oil tank going back to 1971. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property housed an underground storage tank that stored fuel oil used to fire the boilers in the adjacent Armory building, with an estimated installation date around 1971. In October 1995, an oily substance was discovered discharging from a storm drain and traced back to the old UST, triggering containment, tank decommissioning, excavation of overburden and trenches, removal and off-site disposal of contaminated soil and water, vacuum-truck recovery of oil and water, and sealing off associated pipes. Remediation efforts and subsequent investigations continued through at least early 1997, and cleanup remains underway under the Standard Cleanup program. 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 fuel oil release at this property originated from an underground storage tank installed approximately twenty-five years before its 1996 removal — well within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — tank decommissioning, soil and water removal, vacuum-truck recovery, excavation, and multi-year investigation — are the type of progressive-damage cleanup costs that pre-1986 CGL carriers may be obligated to fund. With cleanup still in progress, additional remediation costs may continue to accrue against those same historical policies.

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.
