This property has a documented history as a industrial and manufacturing facility going back to 1970. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
All Seasons Construction (also known as Glacier Excavation Inc.) operated an excavation and construction business at this light industrial property in Redmond, with multiple workshop buildings housing several businesses on site. An above-ground petroleum storage tank documented during a 1991 site visit had produced multiple spills, and heavy oil contamination from leaking equipment was identified on the property. Asbestos-containing demolition debris was found buried on site and is currently managed in-situ to prevent airborne release. Completed work includes tank removal, site regrading for surface water control, building relocation, and soil berm construction; a proposed excavation to achieve significant fill pad reductions has not yet commenced. 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 petroleum contamination at this site traces to an above-ground storage tank estimated to have been installed around 1970 — more than a decade before 1986, when occurrence-based CGL policies were still the prevailing coverage form for industrial operators like this construction and excavation business. The central remediation obligation still ahead — excavation to reduce the contaminated fill pads across the property — represents a substantial unfunded cleanup cost. Historical CGL carriers who issued policies to this operation during the pre-1986 years when the petroleum spills originated may be obligated to fund that upcoming work.
