Trans-Arabian Pipeline years of constant arguing between Saudi Arabia and Syria and Lebanon over transit fees, the emergence of oil supertankers, and pipeline breakdowns, the section of the line beyond Jordan ceased operation in 1976. The remainder of the line between Saudi Arabia and Jordan continued to transport modest amounts of petroleum until 1990 when the Saudis cut off the pipeline in response to Jordan's support of Iraq during the first Gulf War. Today, the entire line is unfit for oil transport. The Trans-Arabian Pipeline was long with a diameter of . When constructed, it was the world's largest oil pipeline system.

Although the Pipeline and Hazardous Materials Safety Administration (PHMSA) has standard baseline incident frequencies to estimate the number of spills, TransCanada altered these assumptions based on improved pipeline design, operation, and safety. Whether these adjustments are justified is debatable as these assumptions resulted in a nearly 10-fold decrease in spill estimates. Given that the pipeline crosses 247 miles of the Ogallala Aquifer, or 14.5% of the entire pipeline length, and the 50-year life of the entire pipeline is expected to have between 11 – 91 spills, approximately 1.6 – 13.2 spills can be expected to occur over
