This property has served as a bus garage, storage, and maintenance facility for King County Metro — formerly the Municipality of Metropolitan Seattle — since Metro began transit operations in 1973. The facility includes registered underground storage tanks and a dedicated fuel building supporting fleet fueling and maintenance. Groundwater sampling has confirmed petroleum contamination well above cleanup levels, with bore pit water showing diesel-range total petroleum hydrocarbons at 190,000 µg/L — 380 times the MTCA Method A cleanup level — and gasoline-range and other petroleum compounds also confirmed above standards. Cleanup is underway under the 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.
King County Metro's Central Base has operated as a bus fueling and maintenance facility since 1973, more than a decade before 1986 — the year occurrence-based Commercial General Liability policies gave way to claims-made forms with absolute pollution exclusions. The petroleum contamination confirmed in groundwater beneath this facility is consistent with decades of fueling operations and underground storage tank use during that pre-1986 window. Remediation costs already incurred and those still ahead — investigation, cleanup design, and active groundwater remediation — represent expenditures that historical CGL carriers from the facility's pre-1986 operational period may be obligated 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.
