Public Works cleanup site — Restorical Research
WA DNR Ellensburg
Ellensburg, Kittitas County

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 Washington State Department of Natural Resources' Southeast Regional Headquarters and a Kittitas County Public Works facility, with buildings constructed in 1977–1978 and a water supply well drilled as early as 1969. The site included a refueling station with underground storage tanks supplying gasoline and diesel fuel for the agencies' fleet vehicles. Cleanup activities have included the removal of two 6,000-gallon USTs in 1998, excavation of approximately 478 cubic yards of contaminated soil, and recovery of 1,400 gallons of contaminated fluids. Quarterly and semi-annual groundwater monitoring has been ongoing since at least 2002, and cleanup work continues 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.

Petroleum contamination at this facility originated from fueling operations that supported government fleet vehicles at a site operational since the late 1960s — well before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion in Washington. The documented remediation costs to date — tank removal, large-scale soil excavation, fluid recovery, and over two decades of groundwater monitoring — represent expenditures tied directly to those pre-1986 operations. With cleanup still underway, historical carriers whose CGL policies were in effect during the facility's early decades may be obligated both to reimburse 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.
