Public Works cleanup site — Restorical Research
WA Army National Guard OMS 5
Kent, King County

Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1980. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Washington Military Department has owned and operated the Kent Readiness Center — an Army National Guard armory — since the early 1980s, with an indoor firing range as a central operational feature of the facility. Lead dust from the firing range's ventilation system migrated to surrounding soil and exterior building surfaces, contaminating areas near downspouts, a stormwater basin, and a driveway. Cleanup activities conducted between May 2006 and October 2007 included excavation of 9.2 tons of lead-contaminated soil, cleaning and scrubbing of contaminated roof surfaces, flashing, and ventilation louvers, plugging of an indoor drain, and installation of particulate capture on the ventilation exhaust unit, with recommendations for ongoing maintenance issued at project close. 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.

The lead contamination at this facility traces directly to indoor firing range operations that began in the early 1980s — before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion in Washington. The continuous accumulation and off-gassing of lead dust from the ventilation system during that pre-1986 operational window is the type of slow, ongoing release those policies were written to address. The documented remediation costs — soil excavation, structural surface cleaning, drainage modifications, and exhaust controls — represent expenditures that historical carriers who issued CGL policies during the facility's pre-1986 years 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.
