Industrial & Manufacturing cleanup site — Restorical Research
Moss G Milan Property
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1929. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This Seattle property operated as a foundry and pattern shop from 1929 to 1949, with industrial activity continuing at the site through 1985. Carcinogenic polycyclic aromatic hydrocarbons (cPAHs) detected in soil are directly linked to the site's former foundry use, found in a discolored soil layer consistent with that history. Remediation under a Voluntary Cleanup Program agreement (2007–2012) included limited soil excavation during a 2010 redevelopment, demolition of on-site buildings, and containment through capping with pavement and an impermeable membrane; a restrictive covenant limiting the property to industrial use is planned. Groundwater monitoring has been ongoing since 2006. 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 cPAH contamination here traces to foundry operations that began in 1929 — more than five decades before the 1986 threshold after which occurrence-based Commercial General Liability policies ceased to reliably cover pollution claims. Pre-1986 CGL carriers who insured the foundry or subsequent industrial operators during that window issued policies with no effective pollution exclusion in Washington and remain potentially liable today. The documented remediation expenditures at this property — excavation, building demolition, containment capping, and years of groundwater monitoring — are costs those historical policies 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.
