This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
The City of Westport Maintenance Yard is a municipal public works facility where perchloroethylene (PCE) was discovered in groundwater in August 2007, traced to historic fueling and maintenance activities at the site. Cleanup under the Voluntary Cleanup Program has included soil excavation, in-situ chemical oxidation via RegenOx injections, installation of perforated piping for electron donor delivery, and injection of 300 gallons of Regenesis 3-D Microemulsion into groundwater. Groundwater monitoring has been conducted since at least 2008, and cleanup work is ongoing. 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 PCE contamination at this municipal maintenance yard originated from fueling and maintenance operations that the site documents characterize as historic — predating the post-1986 shift to claims-made and pollution-exclusion policies. Occurrence-based CGL policies issued to the City during that pre-1986 operational window carried no effective pollution exclusion under Washington law and remain a plausible avenue for cost recovery. The documented remediation work — soil excavation, chemical oxidation, in-situ groundwater treatment, and years of ongoing monitoring — represents exactly the category of cleanup expenditure those historical policies were written to cover.
