Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1956. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property has hosted industrial operations since at least 1956, when Pioneer Enamel began porcelain enamel application work in a building constructed in 1928. The operation generated process wastewater discharged through an interior sump — Metro sampled sludge from that sump in 1987, and Ecology sampled site soils in 1990 following an employee complaint about waste disposal practices. Metals priority pollutants have been identified in groundwater and surface water, with arsenic detected in groundwater at 5.5 µg/L, exceeding the Method A cleanup level. The site is now awaiting cleanup 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.

Porcelain enamel application at this property began approximately 1956 and continued for decades, with process wastewater discharge confirmed as early as 1987 — placing the origin of metals contamination squarely within the pre-1986 window when occurrence-based CGL policies carried no effective pollution exclusion. The cleanup costs this property now faces — site investigation, remediation design, and metals remediation in both groundwater and surface water — could plausibly be funded by historical carriers whose policies were in force during the decades of industrial operations that produced the contamination.

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.
