This property has a documented history as a industrial and manufacturing facility going back to 1892. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property was the location of the Everett Smelter, which operated from approximately 1892 to 1914, refining ores from the Monte Cristo mining district into lead, copper, gold, and silver; an arsenic processing plant was also constructed and operated on the site during that period. Interim actions have included soil placement and retaining wall construction. Planned remediation encompasses soil removal of up to 6,800 cubic yards, capping, in-situ solidification and stabilization, permeable reactive barrier installation, contaminated surface water treatment, and long-term seep-water and compliance monitoring. Estimated costs for site-wide remedial alternatives range from $14.7 million to $20.4 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.
The contamination at this site — arsenic, lead, and associated heavy metals — is the direct product of smelting and ore-refining operations that concluded more than seven decades before 1986, when occurrence-based CGL policies remained the industry standard and carried no effective pollution exclusion. Historical carriers who issued such policies to operators of the smelter or the arsenic processing plant during the facility's active years may be obligated to contribute to remediation expenditures. With projected cleanup costs reaching up to $20.4 million and active work still ahead, both recovery of past interim-action costs and funding for future remediation are plausibly within scope for historical insurance claims.
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.
