"The oil spilled from TC Energy Corp’s ruptured Keystone pipeline was diluted bitumen, the U.S. Environmental Protection Agency (EPA) said on Thursday, adding complications to the cleanup.
The 622,000 barrels per day (bpd) pipeline was shut last week after it spilled 14,000 barrels of oil in rural Kansas, including into a creek. Bitumen tends to sink in water, making it harder to collect than oils that float.
The parts of the pipeline carrying oil from Alberta, Canada, to refineries in Illinois opened on Wednesday at reduced capacity. The ruptured portion that extends from south of Steele City, Nebraska, to a storage hub in Cushing, Oklahoma, remains closed."
