Landfill cleanup site — Restorical Research
National Oil Dump
Tacoma, Pierce County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1925. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This Tacoma property operated as a chemical waste dump for National Oil Co. beginning in 1925, accepting used chemicals for recycling and reuse and disposing of unusable materials on-site. A preliminary assessment of the site's historical environmental impacts was conducted in 1985; no further investigations or remedial actions have been documented since. The site remains classified as Awaiting Cleanup under Washington State's 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.

Chemical waste disposal at this property began in 1925 — more than six decades before the 1986 threshold after which Commercial General Liability policies were routinely issued with effective pollution exclusions. The long-running accumulation of chemical waste and unusable industrial materials from recycling operations is precisely the kind of slow, ongoing release that occurrence-based CGL policies issued to National Oil Co. before 1986 were written to cover. As investigation and remediation planning moves forward, historical carriers whose policies were in effect during those decades of dumping operations may be obligated to fund the cleanup costs now facing the property.

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.
