Industrial & Manufacturing cleanup site — Restorical Research
Seattle Barrel & Cooperage

Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1913. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

Seattle Barrel and Cooperage has operated at this site since 1913, reconditioning fifty-five gallon drums by washing them in hot detergent solution and repainting them — a process that involved draining residual petroleum products and waste materials from used drums. A site hazard assessment identified 111 cubic yards of contaminated soil, with heavy oil, lead, and semi-volatile compounds linked to these industrial drum-handling operations. No active remediation has commenced; the site remains at the assessment and scoping stage. 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 here — petroleum residues, heavy oil, and lead — traces directly to drum reconditioning practices that were ongoing decades before 1986, when occurrence-based Commercial General Liability policies routinely lacked effective pollution exclusions. The contamination was the product of continuous industrial operations dating to 1913, not an isolated spill, making it precisely the type of long-running release those pre-1986 CGL policies were written to address. The costs now facing this property — hazard assessment, remedial design, and excavation of over 100 cubic yards of impacted soil — could plausibly be funded by historical carriers whose policies were in force during the decades of pre-1986 operations.

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.
