 Independent Petrochemical Corporation (IPC), was a wholly owned subsidiary of Charter Oil.On several occasions, and as a courtesy to a customer, IPC arranged for the disposal of waste oil by a St. Louis waste oil hauler, Bliss Oil, with the understanding that Bliss would take the oil to a waste disposal site.In actuality, after Bliss Oil's president tasted the oil to check its suitability for other uses and found the flavor fit, Bliss sprayed it as a dust suppressant at various locations throughout Missouri.
