Industrial & Manufacturing cleanup site — Restorical Research
Block 52 East
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1951. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This Seattle industrial property has been in commercial use since 1948, when the main building was constructed with oil-fired furnace heating. Timken Roller Bearing Co. occupied the site from approximately 1951 through 1978, operating it for industrial and warehouse purposes — including a crane system installed under a 1955 Seattle DCLU permit. Cleanup work at the site has included underground storage tank removals, petroleum-contaminated soil excavations, and ongoing multi-year groundwater treatment and soil remediation. 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 petroleum contamination here traces to underground storage tanks and an oil furnace heating system installed during Timken Roller Bearing's industrial occupancy — operations that predate 1986 by more than three decades. Occurrence-based Commercial General Liability policies issued to operators during that pre-1986 window carried no effective pollution exclusion and remain enforceable today. The documented remediation at this site — UST removals, contaminated soil excavation, and continuing groundwater treatment — represents cleanup expenditures that historical carriers whose policies covered industrial operations here 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.
