* 318,000-bpd Line 64 restarts after 5 days
* Enbridge still developing spill volume estimate
* Canadian cash crude differentials widen
CALGARY, Alberta, March 9 Enbridge Inc
said on Friday it had restarted the remaining segment
of a major U.S. Midwest oil pipeline it was forced to shut down
on the weekend when a deadly traffic accident damaged an
above-ground section in Illinois.
Line 64, the easternmost part of Enbridge's 318,000
barrel-per-day Line 14/64, had been shut since Saturday,
squeezing already tight pipeline capacity for Canadian crude
exports. The Line 14 segment had restarted on Tuesday.
The company is still working on an estimate for the volume
of oil spilled in the incident at a pumping station near the
township of New Lenox, Illinois, about 70 miles (113 km)
southwest of Chicago.
Two people were killed in the fiery wreck that was said to
have occurred when the driver of a car racing an SUV lost
control, smashed through a chain-link fence at the Enbridge
facility and hit the section of pipeline.
The accident exposed just how tight transport capacity to
major U.S. refining markets is for Canadian crude with
production from the Alberta tar sands surging. The situation was
already weighing on prices for Canadian oil versus international
grades before the outage.
The Line 14/64 system, whose volume is equal to about 3
percent of total U.S. oil imports, runs to Griffith, Indiana,
from Enbridge's storage hub at Superior, Wisconsin.
The company had cautioned that the outage could lead to
slow-downs or shutdowns of pipelines between Alberta and
Superior, or lines that feed supply to the major trunk system
from production facilities, but spokeswoman Lorraine Little said
on Friday the company now expects to manage the month's
Despite the restart, Canadian crude spreads widened on
Friday. Western Canada Select heavy blend for April delivery was
quoted at $34.75 a barrel under benchmark West Texas
Intermediate, about $1 wider than on Thursday.
April light synthetic sold for $15 a barrel under WTI, about
a $4 deeper discount than the day before.
Several refineries in major markets, including the U.S.
Midwest, Alberta and the West Coast, have begun planned
maintenance or experienced equipment failure over the past week.
