Project Details

  • Operator: Energy Transfer Partners
  • Current capacity: 240,000 barrels per day (bpd)
  • Proposed capacity:
  • Length: 1,570 kilometers (976 miles)
  • Status: Operating
  • Start Year: 1950[3]


The Mid-Valley pipeline system consists of approximately 976 miles of 20” and 22” crude oil pipelines that originate in Longview, Texas and pass through Louisiana, Arkansas, Mississippi, Tennessee, Kentucky, and Ohio, and terminate in Samaria, Michigan. The pipeline has a nominal capacity of 240,000 bpd, and provides crude oil to a number of refineries, primarily in the midwest United States, including the Lima Refinery and Toledo Refinery.[1] This pipeline also receives crude oil from the Enbridge Mainline Pipeline system for delivery to refineries located in Toledo, Ohio and to Marathon's Samaria, Michigan tank farm, which supplies its refinery in Detroit, Michigan.[4]


The pipeline was owned by Sunoco Logistics.[1] In October 2012, Sunoco became a wholly owned subsidiary of Energy Transfer Partners (ETP),[5] and by 2017 Sunoco took on the name Energy Transfer Partners.[6]

Oil spills

In January 2005 Mid-Valley Oil Pipeline leaked into the Kentucky and Ohio rivers. In response, Sunoco agreed to pay a US$2.57 million penalty, as well as a federal civil penalty of US$300,000 for Clean Water Act violations.[7]

In October 2014, the pipeline leaked approximately 168,000 gallons of crude oil into the Miller Branch Creek of the Tete Bayou, near Mooringsport, Louisiana.[7]

On June 29, 2022, the pipeline leaked over 200,000 gallons of oil into the rural town of Henderson, Tennessee, after a mowing contractor struck the line. The leak spilled directly into Horse Creek, narrowly avoiding contamination of the state's biggest aquifer. At the time, it was the second-largest crude oil spill in Tennessee history, with an estimated cleanup cost of $4.7 million; the EPA indicated that fish, land animals, water, and soil were impacted by the spill, including turtles.[3][8][9]
