This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
The Allnight Air Sweep site in Everett operated as a commercial street sweeping business, deploying truck-mounted industrial vacuums to sweep parking lots and streets under contract. Contamination at the property stems from vehicle leakage, truck maintenance activities, and improper disposal of automotive waste and collected street sweepings; a 1994 notice of violation documented large patches of oil and grease on site consistent with routine operational practices. The site has received an independent site assessment and is awaiting a formal Site Hazard Assessment under the Toxics Cleanup Program, with no active remediation 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 oil-and-grease contamination here is the product of habitual, recurring operations — not a one-time incident — and the 1994 notice of violation describes a pattern of accumulation that by its nature began well before 1986, when occurrence-based CGL policies without effective pollution exclusions were still the industry standard. Policies issued to the operators of this street sweeping business during that pre-1986 window may carry continuing obligations for the contamination those operations produced. The cleanup costs now facing this property — hazard assessment, remedial investigation, and eventual remediation — represent expenditures that historical carriers could plausibly be obligated to fund.
