Enbridge Shuts Line 37 Near Cheecham Alberta After Light Synthetic Crude Released

CALGARY, ALBERTA--(Marketwired - June 23, 2013) - Enbridge Pipelines (Athabasca) Inc., a subsidiary of Enbridge Inc., (TSX:ENB)(NYSE:ENB) shut down and isolated its Line 37 pipeline north of Cheecham, Alberta, at 5:21 a.m. MDT today after our leak detection system detected a potential release from the line.

Field personnel were immediately mobilized to investigate. Light synthetic oil was discovered on the ground approximately two kilometers north of our Cheecham Terminal, approximately 70 kilometres southeast of Ft McMurray.

Initial estimates place the volume of the release at approximately 750 barrels. We are still investigating the cause, however we believe that unusually heavy rains in the area may have resulted in ground movement on the right-of way that may have impacted the pipeline. As a precaution, all other Enbridge pipelines in the area have been shut down including the Athabasca and Waupisoo pipelines.

Enbridge first responders with equipment are on-site and have installed booms which has contained product at the site and the local water bodies. There have been no reports of harm to wildlife.

An Incident Command System has been initiated that will continue around the clock and responders and support resources have been dispatched from Fort McMurray, Lac La Biche, Edmonton, Hardisty, Alberta and Kerrobert, Saskatchewan.

Line 37 was constructed in 2006 and is a 12-inch diameter pipeline that is 17-kilometers long and connects facilities in the Long Lake area to Cheecham and is part of Enbridge's Athabasca system.

Enbridge notified the Alberta Energy Regulator and are working with them, including Alberta Environment, government officials and local aboriginal communities. Enbridge will work with regulators and our community partners to insure this situation is resolved safely and as quickly as possible.
