Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1965. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This Seattle property operated as a bus depot engaged in industrial-scale vehicle maintenance, including steam cleaning engines and draining truck fluids into an on-site pit, with two underground storage tanks — a 500-gallon diesel and a 1,000-gallon gasoline tank — fueling fleet operations. Both USTs were removed in 1990, the same year the site was placed on the state Contaminated Sites List due to confirmed diesel and gasoline contamination. Remediation included in-situ soil treatment of less than ten cubic yards of impacted material, installation and sampling of monitoring wells beginning in 1995, and site hazard assessments planned through at least 2014. Cleanup work remains ongoing under the Standard Cleanup program. 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 bus depot operations — engine fluid dumps and petroleum fueling — that an anonymous caller reported to Ecology in 1991 had been ongoing for years prior, and that the installed UST inventory suggests began as early as the mid-1960s. Those operations fall squarely within the window when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The documented cost trail — UST removal, in-situ soil remediation, multi-year groundwater monitoring, and continued hazard assessments — represents expenditures that historical carriers whose policies were in force during those pre-1986 operations 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.
