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 — and recover costs already spent.

The C-1 Building at this Everett site was developed in 1956 by Alaska Airlines for aircraft engine repair and overhaul, then sold in 1962 to the parent company of Precision Engines, which used it for aircraft engine repair and the manufacture of fuel injection systems alongside sister company Precision Airmotive. A site assessment conducted in 1986 documented improper disposal of chemicals and detected lead contamination, establishing a documented record of hazardous-material releases tied to those industrial operations. Cleanup work has included removal of a 1,000-gallon underground storage tank in 1991, soil excavation in 2001, and remedial excavation of mineral oil-impacted soil; the site currently holds a Cleanup Started status under the Voluntary Cleanup Program, backed by an Integrated Planning Grant from Ecology, with quarterly groundwater sampling anticipated as remediation continues. 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.

Industrial operations at this property — aircraft engine repair, fuel injection system manufacturing, and the routine use of solvents, oils, and metals — began in 1956 and ran for three decades before 1986, when occurrence-based Commercial General Liability policies remained the industry standard and lacked effective pollution exclusions. The 1986 assessment that uncovered improper chemical disposal and lead contamination reflects releases that were already underway during that pre-1986 operating window, directly linking the documented contamination to that insured period. Historical carriers whose CGL policies covered Precision Engines, Precision Airmotive, or their predecessors during those decades may be obligated both to recover the remediation costs already incurred and to fund the cleanup work the site still requires.

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.
