Enbridge Reports Oil Release at Pump Station Facility

CALGARY, ALBERTA -- (Marketwire) -- 06/19/12 -- Enbridge Inc. (TSX:ENB) (NYSE:ENB) has confirmed an oil release at its Elk Point oil pumping station on Line 19 (Athabasca Pipeline), approximately 70 kilometres (43.5 miles) south of Bonnyville, Alberta and approximately 24 kilometres (15 miles) from the town of Elk Point.

The release, which occurred June 18, 2012, is largely contained within the pumping station site. The area was secured and clean-up operations began immediately. There is no risk to public health or safety. Preliminary volume estimates of the release are approximately 230 m3 (1,400 barrels). The cause of the release appears to be a failure of a flange gasket in the pumping station.

Immediately upon Enbridge's detection of the pumping station leak, the pipeline was shut down. Enbridge contacted local emergency response organizations and has notified civic authorities and regulatory agencies.

With the Elk Point pump station isolated and shut down, the line was safely restarted on the afternoon on June 18 and has run normally since that time. However, the line was again shut down the afternoon of June 19 on the order of the Energy Resources Conservation Board (ERCB) as the ERCB and Enbridge continue their investigation. Enbridge is in discussion with the ERCB to determine the appropriate time for a restart of the line.
