Pembina Pipeline Corporation Re-starts Western System Pipeline

CALGARY, July 11, 2011 /CNW/ - Pembina Pipeline Corporation ("Pembina") (TSX:PPL) today announced that its wholly-owned subsidiary, Plateau Pipe Line Ltd., has re-started operations on its Western System pipeline after proactively shutting down the line due to erosion and washout conditions which exposed portions of the pipeline in northeastern British Columbia the weekend of June 25, 2011.

The company confirmed that it did not experience any pipeline breach as a result of the washout conditions, but had shut the pipeline down to minimize the potential risk of a pipeline incident.

"We take the safety of our people and the communities along our pipeline rights-of-way very seriously," said Bob Michaleski, President and Chief Executive Officer. "We are committed to being a responsible operator and implemented these pre-emptive measures to reduce the potential impact of the erosion along our pipeline right-of-way."

Plateau Pipe Line Ltd. had shut down its 12" Western System pipeline in late June, which transports an average throughput of 18,500 barrels of oil per day of oil from Taylor to Kamloops, British Columbia. During the shut down, which lasted 15 days, the company monitored the line by air, land and through its Edmonton Control Centre, conducted integrity inspections of the line, and completed work to stabilize the line before determining it was safe to re-start operations.

Pembina Pipeline Corporation transports crude oil and natural gas liquids produced in western Canada, owns and operates oil sands pipelines and has a growing presence in the midstream & marketing and gas services sectors.  Pembina's common shares (PPL) and convertible debentures (PPL.DB.C) are traded on the TSX.
