Bulk Plant cleanup site — Restorical Research
LTS Trucking
Renton, King County
Restorical Research
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.

This property operated as the LTS Trucking facility in Renton, with a loading dock, warehouse, and underground storage tanks — a 10,000-gallon diesel UST and a 5,000-gallon gasoline UST — serving its fleet operations. The USTs were removed in the late 1980s, and approximately 185 cubic yards of petroleum-contaminated soil were excavated and disposed of in 1996. Groundwater monitoring from 1997 through 1998 confirmed successful mitigation of groundwater contamination, and a Restrictive Covenant was filed in 1999 to manage residual contaminated soil beneath existing buildings, with periodic reviews and post-cleanup controls remaining in place. 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.

Petroleum contamination at this site originated from underground storage tanks that were installed and operated well before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — UST removal, large-scale soil excavation, multi-year groundwater monitoring, and institutional controls — were incurred to address releases tied directly to those pre-1986 fueling operations. With cleanup still subject to ongoing controls and periodic review, historical carriers who issued CGL policies during the facility's operational window may be obligated both to recover past remediation costs and to fund continuing compliance.

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.
