Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Olympic Pipe Line Company Tacoma Delivery Facility — formerly owned by Shell Oil Products U.S. — is a bulk petroleum delivery site that receives refined product via the OPLC pipeline, situated on the Tacoma tide-flats adjacent to a former Shell Bulk Terminal and a ConocoPhillips Bulk Terminal. Documented releases of diesel fuel, gasoline, and trans-mix originating from a pump cooling line, a prover loop, and a sump area were recorded in 1992, 2000, and 2001. Cleanup work under the Voluntary Cleanup Program has included air sparging, ozone sparging, and soil vapor extraction operated from 2006 to 2012, the removal and replacement of a 1,500-gallon underground storage tank (process sump) in 2009, and quarterly groundwater monitoring that has continued since at least 2016. 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 releases at this facility originated from bulk petroleum handling infrastructure — a pump cooling line, a prover loop, and a process sump identified as an underground storage tank — whose installation and operation predate 1986, the period when occurrence-based Commercial General Liability policies covered pollution events without effective exclusions. Contamination tied to those operational components falls squarely within the coverage window of pre-1986 CGL policies issued to the facility's historical operators. The documented remediation costs here — multi-year sparge and vapor extraction systems, a UST removal, and ongoing groundwater monitoring — represent expenditures that historical carriers may be obligated both to recover and to fund going forward.

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.
