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.

Scott Waldal operated an environmental contractor business on this 5-acre Arlington property, using it to store and handle hazardous substances — petroleum, hydraulic oil, paint, 4-chlorotoluene, and chlorinated solvents — held in underground storage tanks, drums, and piping, with many of the tanks reportedly removed from off-site locations and stockpiled here. Initial investigations in 2020–2021 resulted in the removal and off-site disposal of 14 tanks and several drums and buckets of hazardous waste, with liquid wastes segregated, drummed, and transported for disposal; soil excavation, though explicitly recommended, did not occur during this initial phase. The property now sits on Ecology's Confirmed and Suspected Contaminated Sites List under MTCA, with soil remediation, long-term monitoring, and 5-year periodic reviews all still ahead. 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 property traces to Waldal's environmental contractor operation, which accumulated old underground storage tanks and hazardous waste in quantities and over a timeframe that site records suggest likely predates the 1986 regulatory threshold for USTs. The most significant costs here lie ahead of the property owner, not behind: the soil excavation explicitly deferred from the initial removal phase remains unstarted, and the cleanup schedule under MTCA incorporates long-term monitoring and periodic reviews extending years into the future. Historical CGL carriers whose policies covered Waldal's storage and handling operations during the pre-1986 period may be obligated to fund that forthcoming remediation 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.
