CenterPoint Energy natural gas line running through a Minneapolis, Minnesota neighborhood ruptured, and gas from it ignited, caused evacuations to buildings nearby, and Interstate 35W was closed from downtown Minneapolis to Highway 62. There were no injuries. The Minnesota Office of Pipeline Safety later found the pipe there was not designed to handle the load of soil and passing cars, and efforts to shore up the pipeline were incorrectly carried out. A farmer and rancher near White Oak Township, Michigan smelled gasoline on April 13, and discovered gasoline from a products pipeline leaking into a drainage ditch. As of late September, an estimated 460,000 gallons of gasoline had been released, with about 111,000 gallons of it recovered. On May 7, a threaded connection failed on a Keystone Pipeline pump at a station in Sargent County, North Dakota, spilling about 400 barrels of crude oil. Due to a number of other leaks on this pipeline system, Keystone's owner, TransCanada Corporation, was given a Corrective Action Order by PHMSA. An 8-inch NGL pipeline failed in Romeoville, Illinois on May 14, leaking about 4200 gallons of butane. Corrosion inside a casing under a road was the cause of the failure. Corrosion only 2.5 feet from the failure had been seen by a smart pig run in 2007, but was not within action limits at the time. On May 19, a 10-inch crude oil pipeline ruptured near Maysville, Oklahoma. Over of crude were lost. There was no fire. Internal pipeline corrosion was the cause. A 2-inch lateral on a crude oil pipeline ruptured in Huntington Beach, California on July 1. A major road, Goldenwest Street, had to be closed for cleaning and pipeline repairs. Late on July 1, a 12-inch Exxon Mobil crude oil pipeline. also known as the Silvertip Pipeline, ruptured, and spilled about 63,000 gallons of oil into the Yellowstone River in south-central Montana. There was confusion in the pipeline control room, causing a delayed pipeline shutdown. Some residents of Laurel, Montana had to be evacuated. The break near Billings fouled the riverbank and forced municipalities and irrigation districts to close intakes. Exxon later increased the spill size estimate to 1500 barrels in January 2012 after seeing the damage to the pipeline. About 140 people were evacuated starting about 12:15 a.m. Saturday due to concerns about possible explosions and the overpowering fumes. All were allowed to return after instruments showed petroleum odors
