Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1938. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.

Bloch Steel Industries has operated as a scrap iron recycling facility and steel distribution company at this property since 1938, with buildings on site dating to 1930 and 1949. An underground storage tank used to store diesel fuel for operational support leaked petroleum into soil and groundwater over decades of use. Cleanup under the Voluntary Cleanup Program began in 1992 with the removal of the UST and 233.90 tons of petroleum-contaminated soil, followed by on-site land farming, landfill disposal, groundwater monitoring, and free product removal from wells through 1999. Ecology issued a No Further Action determination in 2011. 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 diesel fuel contamination at this site traces to an underground storage tank that had been in service for over thirty years before its removal in 1992 — placing its operation squarely within the era of occurrence-based Commercial General Liability policies that carried no effective pollution exclusion in Washington. Nearly two decades of documented remediation costs — tank removal, soil excavation and treatment, groundwater monitoring, and free product recovery — were incurred to address releases tied directly to those pre-1986 industrial operations. Historical carriers who wrote CGL policies covering this facility during that window may still be obligated to reimburse those cleanup expenditures.

Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.

Recovering Costs from an Older Cleanup

If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.

What We Look For

  • Historical insurance policies (pre-1986)

  • Claims Management & Forensic Accounting

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 — Cost Recovery
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim and negotiate recovery of costs already incurred. Restorical's forensic accounting team re-establishes and documents past cleanup expenditures, managing the claim process to ensure the insurance companies fulfill their obligation in a timely manner.
