Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1928. Historical insurance policies issued during operations at this property and through 1986 could recover the cleanup costs already paid.

This property has operated as a gasoline service station since at least 1928. Six underground storage tanks were removed in 1990, at which time petroleum-contaminated soil was discovered; subsequent investigation documented benzene, lead, TPH-gasoline, and 1,2,4-trimethylbenzene in groundwater, and a vapor intrusion assessment including sub-slab soil vapor and indoor air sampling was completed. The site entered the Voluntary Cleanup Program and has since received a No Further Action determination from Ecology. 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.

Fueling operations at this site began nearly six decades before 1986, the year occurrence-based Commercial General Liability policies ceased reliably covering pollution claims in Washington. The petroleum contamination documented in groundwater — benzene, lead, TPH-gasoline — traces directly to underground storage tanks that were in service throughout that pre-1986 window. Remediation expenditures spanning UST removal, soil cleanup, groundwater monitoring, and vapor intrusion assessment represent costs that historical CGL carriers who insured this station during its decades of pre-1986 operations may still be obligated to cover.

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)
  • Policy numbers, carrier names, and coverage periods
  • Connection between contamination timing and policy period
  • Evidence linking cleanup obligation to insured activity

What We Deliver

  • Historical Coverage Chart
  • Trigger Analysis & Property/Policy Nexus
  • Coverage strategy with recommendations
  • Insurance funding for your remediation
  • 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.
