April 10 (Reuters) - TransCanada Corp TRP.TO said it aims
to restart the 590,000- barrel-per-day Keystone crude pipeline
by Sunday, after it received American authorization the previous
day to do so at reduced pressure.
The pipeline, which delivers light and heavy crude from
Hardisty, Alberta, to Cushing, Oklahoma, and Illinois, was shut
on April 2 after a potential leak was discovered in South
Dakota.
