Industrial & Manufacturing cleanup site — Restorical Research

Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1883. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property was developed as a brewery in the late 1800s and operated continuously as the Rainier Brewery and bottling plant until 1996, with operations spanning kegging, bottling, warehouse storage, and vehicle maintenance. Cleanup activities under the Voluntary Cleanup Program have included soil excavation, free product extraction, in-situ treatment with oxygen-releasing compounds, and multi-year groundwater monitoring. Ongoing remediation work also addresses PCB and lead paint removal and storm drain cleaning across the property. 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.

Contamination at this site — petroleum hydrocarbons, PCBs, and lead — originated from brewery and industrial operations that began more than a century before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The documented remediation expenditures — soil excavation, free product recovery, in-situ treatment, groundwater monitoring, PCB abatement, and lead paint removal — represent costs tied directly to those decades of pre-1986 operations. With cleanup still underway, historical carriers who issued CGL policies during that operational window may be obligated both to recover past remediation costs and to fund the work that remains.

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.
