This marina property housed a 2,000-gallon bare steel underground storage tank used for gasoline — an uncoated tank with no corrosion protection, characteristics consistent with installation before 1986. A failed tightness test triggered a release investigation, and the abandoned tank, reported empty since June 2022, was removed in May 2025. Groundwater sampling confirmed petroleum hydrocarbons (TPH), polycyclic aromatic hydrocarbons (PAHs), 1-methylnaphthalene, and lead at concentrations exceeding MTCA cleanup levels, with petroleum and lead also detected in surface water and sediment. Cleanup is underway under Washington's Standard Cleanup program. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
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 at Lakebay Marina traces to a bare steel underground storage tank whose physical characteristics — uncoated steel, no corrosion protection, no compliance tagging — place its installation well before the 1988 EPA UST regulations and almost certainly before 1986. Occurrence-based CGL policies issued during that pre-1986 operational window carried no effective pollution exclusion in Washington. The remediation costs now being incurred — tank removal, contamination investigation, and cleanup of petroleum hydrocarbons and lead across groundwater, surface water, and sediment — represent expenditures that 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.
