This property has a documented history as a landfill going back to 1900. Historical insurance policies issued during those prior operations and through 1986 could recover the cleanup costs already paid.
The Newhalem Dump served as a municipal disposal site for the City of Newhalem from the early 1900s through 1971, receiving household refuse, garbage, and tunnel excavation waste across two component dumpsites. One dumpsite closed in 1955 and the other in 1971; closure activities included covering the sites with native soils and gravels in the early 1970s, with municipal wastes trucked out of one dumpsite by a private contractor after its closure. Seattle City Light continues to maintain the soil cover at one of the sites. The site has received a No Further Action determination under Ecology's Standard Cleanup program. 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.
Municipal waste disposal at this property began more than eight decades before 1986, during the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The contamination potential from decades of landfill operations — household refuse, municipal wastes, and excavation debris deposited directly into the ground — represents the kind of gradual, long-duration environmental exposure these pre-1986 policies were designed to cover. Historical carriers who provided CGL coverage to the operators during those decades of active disposal may still bear obligation for the remediation and closure costs already incurred at the site.
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.
