Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property is a Burlington Northern/Santa Fe Railroad right-of-way along the Seattle Ship Canal, with historical land uses that include railroad tracks and sidings, machine shops, manufacturing, fuel storage, and marine industries — and with current railroad tracks and operations still present on the corridor. Contamination has been confirmed at the site, with petroleum hydrocarbons (TPH), carcinogenic polycyclic aromatic hydrocarbons (cPAHs), diesel, oil, and lead identified in soil and groundwater consistent with those long-term industrial and railroad activities. Ecology has determined that further investigation or cleanup action is required under the Standard Cleanup program, and future construction activities are expected to encounter contaminated soil and groundwater, with provisions for handling, treatment, and disposal required in bid documents. 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 mix of contaminants documented here — petroleum hydrocarbons, cPAHs, diesel, oil, and lead — is the signature of railroad and heavy industrial operations that were already well-established before 1986, as confirmed by a 1983 USGS topographic map showing the physical setting in place at that time. Occurrence-based Commercial General Liability policies issued to the operators and right-of-way holders during that pre-1986 window had no effective pollution exclusion in Washington and remain legally enforceable today. The remediation costs now anticipated at this site — contamination investigation, soil and groundwater handling during construction, treatment, and disposal — represent expenditures that historical carriers whose policies were in force during those industrial operations may be obligated to fund.

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.
