All of NuStar Energy L.P.’s crude oil and refined product pipelines are operated via satellite communication systems from one of two central control rooms located in San Antonio and Dumas, Texas. Each control center can provide backup capability for the other, and each center is capable of monitoring and controlling all of the pipelines. There is also a backup control center located at our south San Antonio refined product terminal.

The control centers are equipped with state-of-the-art computer systems designed to continuously monitor real time operational data, operate equipment associated with the delivery of crude oil and refined products, and control safety measures to ensure smooth and safe operations of our pipelines.
