Industrial & Manufacturing cleanup site — Restorical Research
Balmer Yard BNR
Seattle, King County
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.

Balmer Yard and the adjacent BNSF Interbay Railyard have a documented history of large-scale petroleum operations — locomotive fueling, a Bunker C oil tank, diesel storage, and a caboose fueling line — all identified as sources of subsurface contamination. Since 1993, BNSF Railway Company has voluntarily conducted product recovery from groundwater, removing over 1,700 gallons of diesel and Bunker C LNAPL by 2009, along with tank removals, containment liner installation, well redevelopment, and multi-year groundwater monitoring. The site remains in Awaiting Cleanup status; formal remediation has not yet commenced. 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 Balmer Yard originates from fueling infrastructure and operations that predate 1986 — a former Bunker C oil tank documented in a 1991 report, a caboose fueling line leak, and locomotive maintenance activities spanning decades before that cutoff. The remediation work still ahead — full-scale LNAPL recovery, remedial investigation and design, and long-term groundwater management — will carry substantial costs. Pre-1986 Commercial General Liability policies issued to operators during those fueling years had no effective pollution exclusion and may be a source of funding for exactly the cleanup obligations this site has yet to discharge.

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.
