NuStar Energy L.P., now a subsidiary of Sunoco LP, operates a substantial network for the transportation, terminalling, and storage of various liquid products across the United States and Mexico. The company also engages in the marketing of refined petroleum products. Its operations are primarily categorized into three segments: Pipeline, Storage, and Fuels Marketing. The Pipeline segment is dedicated to moving refined products, crude oil, and anhydrous ammonia through an extensive system. The Storage segment encompasses terminal and storage facilities that provide services for crude oil, refined products, specialty chemicals, and a growing range of renewable fuels, including ethanol, biodiesel, and renewable diesel. This segment also offers handling and other related services for these liquids. The Fuels Marketing segment manages bunkering operations, primarily along the Gulf Coast, and conducts various blending activities, as well as the procurement of petroleum products for resale. As of May 2024, NuStar's integrated system includes approximately 9,500 miles of pipeline and 63 terminal and storage facilities, providing roughly 49 million barrels of storage capacity. These assets support operations throughout key regions of the United States and Mexico. NuStar Energy L.P. was established in 1999 and maintains its headquarters in San Antonio, Texas. In May 2024, the company was acquired by Sunoco LP in an all-equity transaction, making it a wholly-owned subsidiary, with its common units ceasing trade on the New York Stock Exchange.
