Industrial & Manufacturing cleanup site — Restorical Research
Olympian Precast
Redmond, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1965. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as a precast concrete manufacturing plant from at least 1965 until 2023, with on-site fuel storage — gasoline, diesel, and Bunker C — integral to production and equipment maintenance throughout that span. Underground storage tanks were installed as early as 1961 for bunker oil and 1966 for other fuels, and cleanup activities have included removal of 10,000-, 3,000-, and 1,000-gallon USTs, a 2015 remedial excavation of 40 cubic yards of contaminated soil, installation of wastewater treatment systems with oil-water separators, on-site soil biological degradation, upgraded petroleum containment, and ongoing quarterly groundwater monitoring. Cleanup work is continuing under the Voluntary 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 industrial property originated from fuel storage and equipment operations that were underway by at least 1965 — more than two decades before 1986, when occurrence-based CGL policies still carried no effective pollution exclusion. USTs placed in service in the 1960s represent precisely the kind of pre-1986 exposure that historical carriers remain obligated to address. The remediation trail here — multiple tank removals, soil excavation, wastewater treatment, and long-term groundwater monitoring — documents expenditures tied directly to those decades-old operations, and future cleanup costs may likewise be recoverable from historical policies issued during the plant's active years.

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.
