Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1953. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

The Loomis Armored Transport facility at 5200 E Marginal Way S has operated as an armored car dispatch and private fleet fueling center since 1953, with underground storage tanks dispensing gasoline and diesel for the vehicle fleet throughout that period. A 1990–1991 cleanup removed three USTs and excavated approximately 200 cubic yards of petroleum-contaminated soil, while a soil vapor extraction system treated an additional 150 cubic yards of impacted soil in situ. Despite confirmation sampling verifying initial MTCA compliance, the site remained on Ecology's active lists and was subject to a Site Hazard Assessment in 2013, indicating that remediation obligations extend across a multi-year project lifespan. 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 traces to UST operations that Loomis ran continuously from 1953 — more than three decades before 1986 — meaning multiple years of occurrence-based CGL coverage were in force during the period the underground releases were occurring. The expenditures already documented — three UST removals, 200 cubic yards of soil excavation, and in-situ vapor extraction — represent recoverable past costs. Critically, the 2013 Site Hazard Assessment placed the site back on Ecology's active roster, confirming that future remediation obligations remain open; historical carriers whose policies covered Loomis fleet operations during that pre-1986 window may be obligated both to reimburse completed work and to fund the cleanup the site still requires.

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.
