TransCanada is reaffirming its plan to restart the Keystone oil pipeline from Canada to the Midwest on Saturday, although rainy weather is hampering the company's efforts.
TransCanada shut down the 2,100-mile pipeline Wednesday after tests showed possible safety issues. A company spokesman said Friday that no leaks have been detected but declined to provide more specifics until the pipeline is inspected.
The pipeline carries about 590,000 barrels of crude per day from Canada to facilities in the Midwest. The problems were detected in a section of the line between Missouri and Illinois.
Crude supplies are plentiful across the U.S. so the temporary closure isn't expected to affect refinery production or retail gas prices.
