This property has a documented history as a industrial and manufacturing facility going back to 1958. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This Tacoma property has been in continuous industrial use since at least 1958, first as the home of Bay Chemical Company — which manufactured zinc sulfate and calcium chloride from 1958 through 1975 — and subsequently as the operating base of Airo Services Inc., a firm providing industrial and marine cleaning, chemical and oil spill response, and hazardous waste transportation. Cleanup activity dates to 1978. A major removal action between July and December 2008 recovered 114 drums, approximately 100 cubic yards of contaminated solids, 8,000 gallons of free product, and 70,000 gallons of oily water, and included the physical removal of on-site tanks. Remediation continues under the Voluntary 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.
Chemical manufacturing and industrial cleaning operations at this property began nearly three decades before 1986, when occurrence-based Commercial General Liability policies were still the industry norm and carried no effective pollution exclusion in Washington. The contamination profile here — petroleum free product, oily water, drummed hazardous materials, and chemically impacted soils — reflects exactly the kind of slow, diffuse release from ongoing industrial handling that pre-1986 CGL policies were written to cover. Historical carriers whose policies were in force during Bay Chemical's manufacturing years or Airo Services' spill-response operations may be obligated to fund continued remediation and to recover the substantial removal costs already incurred.
