This property has a documented history as a industrial and manufacturing facility going back to 1974. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
MAMCO Manufacturing Company, an aerospace parts production facility, occupied this property and conducted metal plating and vapor degreasing operations using industrial solvents including trichloroethylene (TCE) and 1,1,1-trichloroethane (TCA), with operations expanding to the site by 1974. Cleanup work under the Voluntary Cleanup Program has included closure-in-place of a 2,000-gallon heating oil underground storage tank, collection of waste sludge from a sanitary sewer vault, and management of investigation-derived waste. A Remedial Investigation and Feasibility Study has been completed, identifying cleanup alternatives with estimated costs ranging from $1.44 million to $3.694 million. 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 chlorinated solvent contamination at this property — trichloroethylene and TCA released through aerospace degreasing and metal plating operations that began in the 1970s and early 1980s — originated well before 1986, when occurrence-based Commercial General Liability policies still lacked an effective pollution exclusion. Carriers who issued CGL policies to MAMCO or its predecessors during that pre-1986 operational window may remain obligated under those occurrence-based forms. With remediation cost estimates reaching $3.694 million, this site presents a documented liability trail that historical insurers may be required both to recover past expenditures and to fund the cleanup work ahead.
