Public Works cleanup site — Restorical Research
Puget Power Auburn Service Center
Auburn, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1969. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property served as the Auburn Service Center for Puget Sound Power & Light Company, constructed in 1969–1970 and used for vehicle maintenance, fuel dispensing for utility line trucks, and utility pole storage. Cleanup activities ran from 1993 to at least 2012 under the Standard Cleanup program, encompassing removal of underground storage tanks, excavation of over 3,000 cubic yards of contaminated soil, on-site soil treatment through landfarming and screening of 1,560 cubic yards, pumping and land-application of 20,000 gallons of excavation water, and ongoing groundwater monitoring. Cleanup work is ongoing. 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 facility — petroleum hydrocarbons from fueling operations and pentachlorophenol from the pole storage yard — originated from utility maintenance activities that began in 1969, more than fifteen years before 1986. Occurrence-based CGL policies issued to Puget Sound Power & Light during that pre-1986 operational window carried no effective pollution exclusion under Washington law and remain enforceable today. Nearly two decades of documented remediation expenditures — tank removals, large-scale soil excavation and treatment, water management, and long-term monitoring — represent costs the historical carriers 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.
