Enbridge Inc. said on Friday that it returned its 491,000 barrel-a-day (BPD) Line 5 oil pipeline to service after repairing a leak in Michigan.

"We will have an update on Line 1 later today," company spokeswoman Lorraine Little said in an e-mail.

The company had shut Line 5, which is running from Superior in Wisconsin to Sarnia in Ontario, on Thursday to repair a small leak, estimated to have been less than three barrels at a site in Arenac County, Mich.

Enbridge also shut Line 1, a 237,000 BPD line that extends to Superior from Edmonton, due to high inventories at the end of that segment and lowered pressure on Line 5 to investigate other possible trouble spots of the leak.

"The temporary incremental pressure restriction is on Line 5 and will last until a review of similar features from inspection tool runs has been conducted," Ms. Little said.

The company's pipelines carry the bulk of Canada's crude exports to the United States.
