This property has a documented history as a industrial and manufacturing facility going back to 1904. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as a manufactured gas plant from 1904 to 1956, producing carbureted gas from bituminous coal with associated gas holders, oil tanks, tar holders, and extraction equipment. Cleanup activities under the Standard Cleanup program have included removal of underground storage tanks in 1993 and 1994, excavation of 421 cubic yards of petroleum-impacted soil in 1998, DNAPL recovery, injection of Oxygen Release Compound into wells, closure of tar holder vessels, concrete capping, and installation of a 300-foot sheet pile barrier wall for containment. Groundwater monitoring has been ongoing since 1993, with future remediation alternatives estimated between $1.4 million and $3.2 million. 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.
Contamination at this site — coal tar, dense non-aqueous phase liquids, and polycyclic aromatic hydrocarbons characteristic of manufactured gas production — originated from industrial operations that began more than eight decades before 1986. Occurrence-based CGL policies issued to the plant's operators during that pre-1986 window carried no effective pollution exclusion under Washington law and remain enforceable today. The documented remediation expenditures already incurred and the millions in anticipated future cleanup costs represent obligations that historical carriers may be required both to reimburse 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.
