ELK POINT, Alta. - Enbridge Inc. has restarted a pumping station that caused 230 thousand litres of crude oil to spill northeast of Edmonton more than a week ago.

The company says it restarted the pumping station near Elk Point on Sunday after receiving approval from the Energy Resources Conservation Board.

The spill occurred because of a failed gasket, and Enbridge (TSX:ENB) says it has replaced the gasket and tested all other gaskets at other pumping stations along the line.

Enbridge says contaminated soil and free product is being removed from the site for processing and disposal.

The leak occurred in a field and the ERCB has said it didn't get into any standing water or waterways, while Enbridge said the spill has had no impact on wildlife or water.

The Athabasca pipeline was shut down for several hours after the leak was detected on June 18, but the ERCB ordered the line shut down again until certain conditions were met.

The board, which regulates pipelines in Alberta, gave the company the OK to restart the line at 11:30 p.m. on June 19.

Industry figures show at least 3.4 million litres of hydrocarbons have leaked from pipelines in the province every year since 2005.
