This property has a documented history as a landfill going back to 1974. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
The Horn Rapids Landfill has been permitted for disposal of municipal solid waste since 1974, owned and operated by the City of Richland Public Works Department on a 275-acre city-owned parcel near Twin Bridges Road and State Route 240. Volatile organic compounds from landfill gas have migrated into groundwater, prompting multi-year remediation that includes installation and ongoing operation of a landfill gas extraction and collection system, closure of Phase 1 in 2011 with Phase 2 closure anticipated in 2021, and long-term groundwater monitoring supported by natural attenuation. The landfill expanded operations in the fall of 2020 and remains an active municipal waste facility. 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.
VOC contamination in groundwater at this site traces directly to landfill gas generated by decades of municipal solid waste disposal that began in 1974 — twelve years before occurrence-based CGL policies gave way to claims-made forms with absolute pollution exclusions. The remediation expenditures already incurred — landfill gas extraction infrastructure, phased closure and final cover installation, and years of groundwater monitoring — along with costs still ahead represent the kind of long-tail environmental liability that historical carriers may be obligated both to reimburse and to continue funding under policies issued during that pre-1986 operational window.
