Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1965. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.

This site is part of the Olympic Pipe Line Company's underground petroleum pipeline system, constructed beginning in the mid-1960s to transport refined petroleum products from north Washington refineries to bulk terminals and distribution facilities. A release from a block valve at this location was discovered in August 1989 during a Phase II environmental study, with petroleum hydrocarbons — including TPH and BTEX — migrating through groundwater from the valve site toward the Green River. The site was addressed through the Voluntary Cleanup Program and has received a No Further Action determination. 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 Olympic pipeline system was constructed and operational from the mid-1960s — more than two decades before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion. The petroleum release discovered at this block valve in 1989 originated from infrastructure installed and operated during that pre-1986 policy window, and the resulting groundwater contamination with TPH, BTEX, diesel, and gasoline required remediation through the Voluntary Cleanup Program. Historical CGL carriers who covered the pipeline's operations during the 1960s, 1970s, and early 1980s may bear obligation for the cleanup costs incurred to address this release.

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.

What We Look For

  • Historical insurance policies (pre-1986)

  • Evidence linking cleanup obligation to insured activity

What We Deliver

  • Historical Coverage Chart
  • Trigger Analysis & Property/Policy Nexus

  • Claims Management & Forensic Accounting

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.
