This case study involves a hazardous waste/an environmental engineering expert’s assessment of the transportation of chemical supplies such as liquid propane (LP) gas and anhydrous ammonia to farms in the Midwest. The plaintiff in this case – a business owner that distributes LP gas -owns large storage tanks and distributes to more than 150 small farms. The plaintiff’s company purchases the fuel from large corporations such as Conoco Phillips, then hires a third party OTR logistics company to transport the fuel from the supplier to his distribution facility. The defendant’s company transports a number of liquefied substances to farms, including anhydrous ammonia, which is typically used as a pesticide/herbicide on farms. When the plaintiff purchased 18,000 gallons of LP, the defendant was called to transport it. The defendant used two 9,000-gallon tanker trailers that had been previously used to transport anhydrous ammonia. The defendant admits that he did not properly clean out the vessels prior to transporting the LP. 18,000 gallons of fuel were then delivered to the plaintiff’s distribution facility and later dispersed to numerous farms. The fuel has been proven to be tainted with anhydrous ammonia, and it has been introduced to hundreds of farms where it has caused tens of millions of dollars in damage. As a result of this damage, the plaintiff’s business went bankrupt.
