The Sunoco Logistics Crude Oil Pipeline System consists of approximately 4,900 miles of crude oil trunk pipelines and 500 miles of crude oil gathering pipelines in the southwest and midwest regions of the United States. For more information on all of our assets and on their locations, visit our Asset Map.
Our pipelines in the southwest United States consist of approximately 2,950 miles of crude oil trunk pipelines and approximately 300 miles of crude oil gathering pipelines in Texas. The Texas system is connected to the Mid-Valley pipeline, other third-party pipelines and our Nederland Terminal. We also own and operate a crude oil pipeline and gathering system in Oklahoma. This system contains approximately 850 miles of crude oil trunk pipelines and approximately 200 miles of crude oil gathering pipelines. We have the ability to deliver substantially all of the crude oil gathered on our Oklahoma system to Cushing.
Our pipelines in the midwest United States consist of approximately 1,000 miles of a crude oil pipeline that originates in Longview, Texas and passes through Louisiana, Arkansas, Mississippi, Tennessee, Kentucky and Ohio, and terminates in Samaria, Michigan. This pipeline provides crude oil to a number of refineries, primarily in the midwest United States. In addition, we own approximately 100 miles of crude oil pipeline that runs from Marysville, Michigan to Toledo, Ohio, and a truck injection point for local production at Marysville.
Included in our Crude Oil Pipeline System is a 91% interest in Mid Valley Pipeline Company, a crude oil pipeline, that we operate, running from Longview, Texas to Samaria, Michigan and a 60.3% interest in West Texas Gulf Pipe Line Company, a crude oil pipeline, that we operate, running from Colorado City to Goodrich and Longview, Texas. We also own a 37% interest in the Mesa Pipeline system, a crude oil pipeline running from Midland, Texas to Colorado City, Texas.
Nearly all of our crude oil pipelines are common carrier lines, and the tariff rates on all of our pipelines (wholly owned and joint venture) are regulated by either the Federal Energy Regulatory Commission (for interstate movements) or individual state agencies (for intrastate movements).
