Heating Oil Tank cleanup site — Restorical Research
Flint Ink Building
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a property with a heating oil tank predating 1986. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

One underground storage tank was removed from the Flint Ink Building in Seattle in 2000, at which point approximately 600 gallons of fuel oil sludge and 1,400 gallons of additional sludge and rinsate water were disposed of off-site. Vents and lines were capped and sealed in place, and the excavation was backfilled with concrete debris and pea gravel. Site management and regulatory closure under the Standard Cleanup program concluded in 2012. 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 heating oil tank that contaminated this property was installed and operated for decades prior to its 2000 removal — a timeline consistent with pre-1986 operations, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The documented remediation work here — UST removal, sludge disposal, site restoration, and twelve years of regulatory oversight — represents real cleanup expenditures tied directly to that historical tank operation. Historical carriers who issued CGL policies during the tank's operational decades may still bear obligations to recover those costs.

Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.

Recovering Costs from an Older Cleanup

If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.

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 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
