Preliminary Site-Specific Analysis

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

This property operated as a Penske Truck Leasing facility at 12840 48th Avenue South in Tukwila, with underground storage tanks supporting fueling and maintenance of a commercial truck fleet. The site has been on Washington's Confirmed and Suspected Contaminated Sites List since 1990, and cleanup activities have included the removal of former underground storage tanks and related remediation work. Soil contamination above regulatory levels remains near the former tank locations, and further cleanup action is still required. 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 contamination at this site is tied to historical fueling and maintenance operations and former underground storage tanks — the kind of gradual, operations-driven release that occurrence-based CGL policies issued before 1986 were designed to cover. With the site listed as contaminated since 1990 and cleanup still underway, the remediation cost trail continues to grow. Historical carriers who provided CGL coverage during the pre-1986 operational window may be obligated both to recover past cleanup expenditures and to fund the remaining work.

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.
