Sections of the TransCanada Corp Keystone oil pipeline remains closed, awaiting investigation, following a potential leak near Louis, Missouri.
Crews were sent to assess the suspected leak, located between Steele City, Nebraska and Patoka, Illinois, where the pipeline had been closed.
The pipeline that carries 590,000 barrels per day, is critical to transporting Canadian crude from Alberta to US refineries.
Two other pipelines near the release site will be evacuated in order to find the source of the leak, according to Darius Kirkwood, a spokesman for the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration.
Expanding Canadian production is increasing pressure on pipelines and have forced the Albert provincial government to order cuts to production last month. The increase demand comes following the US sanctions imposed on Venezuela’s PDVSA.
