Northern Tier Energy LLC

Our refining business primarily comprises operations of a 74,000 barrels per day (“bpd”) refinery, located in a suburb of St. Paul, Minnesota. We are one of only two refineries in Minnesota and one of four refineries in the upper Great Plains area within the PADD II region. Our strategic location allows us direct access, primarily via the Minnesota Pipe Line, to a variety of locally sourced and Canadian crude oils, as well as the ability to distribute our refined products throughout the midwestern United States. Our refinery produces a broad slate of refined products including gasoline, diesel, jet fuel and asphalt, which are then marketed to resellers and consumers in the PADD II region.
