* Pipeline to run at reduced pressure for up to 24 hours
* TransCanada to talk with customers regarding impact
* Oil prices fell, partly on expectation of the restart
CALGARY, Alberta, Oct 22 TransCanada Corp
said on Monday it had restarted its major oil pipeline
to the central United States from Canada following a five-day
outage to check for a potential defect on the line in the U.S.
TransCanada, the country's largest pipeline company, said it
would operate the 590,000 barrel-a-day Keystone pipeline at
reduced rates for up to 24 hours while it completes its testing.
The outage of the line, which extends to southern Illinois,
and the Cushing, Oklahoma, storage hub from Hardisty, Alberta,
will affect scheduled shipments for this month, though the
extent is not yet known, spokesman James Millar said in an
"We will be having direct discussions with our customers
regarding the impact this will have on their deliveries to us,"
The line, which can move up to a quarter of Canada's crude
exports to the United States, will return to regular contractual
deliveries in November, he said.
The unplanned shutdown pushed up oil prices last week, but
they have since fallen back. November crude on the New York
Mercantile Exchange sank $1.32 to $88.73 a barrel on Monday on
economic worries and expectations that Keystone would restart.
TransCanada shut the pipeline late Wednesday when an in-line
inspection tool detected what the company called a "small
anomaly" on the pipe.
It did not give the location, but the U.S. Pipelines and
Hazardous Materials Safety Administration said it had sent an
inspector to observe repairs on a section between Missouri and
The pipeline is the first phase of TransCanada's overall
Keystone system and has been in operation since 2010.
The next phase, between Cushing and Gulf Coast refineries, is
under construction amid opposition from some landowners. The
contentious Keystone XL project, between Alberta and southern
Nebraska, still requires U.S. federal approval after U.S.
President Barack Obama rejected the initial application early
TransCanada has re-applied to build that $5.3 billion portion
of the system, hoping for an approval early next year.
