CALGARY, Alberta, Aug 6 Enbridge Inc (ENB.TO)
extracted the ruptured section of pipeline on Friday that had
caused crude oil to foul part of southern Michigan, but U.S.
regulators will have the final say on any schedule for
restarting the line.
With start-up timing still unknown, a third U.S. refinery
has been forced to cut output due to a shortage of crude that
would normally flow on Enbridge's Line 6B.
The 190,000 barrel a day pipeline broke open on July 26
near Marshall, Michigan. The line serves refineries in
Michigan, Ohio, Pennsylvania and Ontario that produce more than
700,000 barrels a day.
A new section of pipe, replacing the damaged one that will
be sent to Washington for analysis, could be in place this
weekend, said Steve Wuori, president of Enbridge's liquids
However, the company, which ships most of Canada's crude
oil exports to the United States, must work with the U.S.
National Transportation Safety Board and Environmental
Protection Agency on the plans and timing for resuming flows of
crude on the line, he said.
"That's dependent on determination when we finish the
removal of the pipe and replacement of it. We don't have a
specific restart time," Wuori said during a conference call.
When oil flows again, the pipeline will run at reduced
rates until regulators are convinced it is safe, Enbridge Chief
Executive Pat Daniel said.

PROBE OF ENTIRE LINE URGED
Michigan Representative Mark Schauer, whose congressional
district includes the spill zone, called on the U.S. Department
of Transportation and Enbridge to ensure the safety of the
entire pipeline to Sarnia, Ontario, from Indiana, and hold a
public meeting on the findings, before restarting it.
The outage caused more headaches for refiners. Sunoco Inc
(SUN.N) was running its 160,000 barrel a day Toledo, Ohio,
refinery at reduced rates, a source said. [ID:nN06239668]
It followed United Refining Co, which reduced rates 35
percent at its Warren, Pennsylvania, refinery, and BP Plc's
(BP.L) and Husky Energy Inc's (HSE.TO) Toledo plant, which also
Sarnia-area refiners, including Imperial Oil Ltd (IMO.TO),
Suncor Energy Inc (SU.TO) and Royal Dutch Shell (RDSa.L), have
reported no reduction in output, but have been forced to
scramble for alternative supplies on other pipelines.
The outage has pressured prices for Canadian heavy crude on
the cash market, trading sources have said.
The July 26 rupture spilled an estimated 19,500 barrels of
heavy Cold Lake Blend crude into the Kalamazoo River system,
forcing a cleanup effort involving more than 800 workers and
120,000 feet (36,580 metres) of containment and absorbent
U.S. officials and the company said oil sheen on the river
is dissipating as cleanup efforts continue in the region.
The spill represents one of the largest pipeline leaks in
recent U.S. history. It arguably gained increased profile
against the backdrop of the much bigger BP disaster in the Gulf
Enbridge shares fell 4 Canadian cents to C$51.72 on the
Toronto Stock Exchange on Friday. Its U.S. affiliate, Enbridge
Energy Partners (EEP.N), rose 13 cents to $57.04 in New York.
