Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1904. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as part of the Lake Washington Belt Line railroad from 1904, with rail spurs serving light industrial companies through approximately 1974. Contaminated soil associated with those historical rail operations — found across six areas including locations where railroad ties and rails had been left in place — prompted a major excavation campaign in May and June 2021 that removed approximately 3,190 tons of impacted material. Groundwater monitoring wells have been proposed and data collection, including a Terrestrial Ecological Evaluation, remains ongoing as of 2022–2023. 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 contamination at this property — petroleum hydrocarbons, polycyclic aromatic hydrocarbons, metals, and creosote from railroad tie treatment — originated from rail operations that ran from 1904 through approximately 1974, entirely within the era when occurrence-based CGL policies carried no effective pollution exclusion. The source of the contamination is confirmed to be historical, not a recent release, which means policies issued to the railroad operators and industrial users of the rail spurs during that pre-1986 window remain enforceable today. The site's documented remediation expenditures — nearly 3,200 tons of excavated soil plus multi-year groundwater assessment and ecological study — represent costs the historical carriers 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.
