(Adds comment from Enbridge in second paragraph)
CALGARY, Alberta Feb 21 Part of the shut
Enbridge Inc 2A pipeline in Alberta will need to be
drained for several days, Canada's National Energy Board said on
Tuesday, and it is not clear when shipments will resume.
Enbridge will repair the line after the ongoing cleanup and

cubic meters spilled because 20 km of the 24-inch (61-cm) 2A

Enbridge said on Monday downstream operations were normal,
but there was no estimated date for restarting the line. The
