A petroleum company continues to replace gasoline it delivered to nearly two dozen Minnesota communities because it contains too much ethanol. The gas came from the Magellan Midstream Partners Petroleum plant on Highway 68 in Mankato. A Magellan spokesperson says “an operational issue” caused the gas to contain more than 10% ethanol. The high ethanol gas has been traced to 21 communities, where Magellan has been “reclaiming” the gas and replacing it with gas from other terminals in the area, a project which is now nearly complete. The communities involved include Mankato, North Mankato, New Ulm, Redwood Falls, Sleepy Eye, Albert Lea, Austin, Renville, Owatonna, Olivia, Winnebago, Le Sueur, Springfield, St. Peter, Belle Plaine, Blue Earth, Hector, Winthrop, Morgan, Gaylord and Fairmont.
