TransCanada announced on Monday that it had shut down the Keystone Pipeline over concerns of a possible leak in South Dakota.
An investigation is underway after workers found signs of oil on an area of land about four miles away from the Freeman pump station on Saturday, the Wall Street Journal reports. TransCanada is cooperating with the authorities and will not reopen the pipeline until the investigation is complete.
No signs of serious environmental impact have been reported yet.
