On December 16, 2010, the National Energy Board (NEB) approved the application for the construction and operation of the Mackenzie Gas Project. The Project includes the 1,196 kilometer Mackenzie Valley Pipeline, three onshore natural gas fields and a 457 kilometer pipeline to carry natural gas liquids from near the coast of the Beaufort Sea to northwestern Alberta and onwards to southern markets. The NEB attached 264 conditions to the Project's approval in areas such as engineering, safety and environmental protection. The NEB will monitor the Project throughout its lifespan to ensure these conditions are being met.

The NEB began hearing evidence in January 2006 on five applications filed by a number of parties, including lead partner Imperial Oil. The Board held over 58 days of hearing sessions in 15 communities throughout the Northwest Territories and northern Alberta.

To move forward, the NEB's decision must now be approved by the Federal Cabinet. If the Project is approved, construction is expected to begin in 2014 and the pipeline is scheduled to be in operation by the end of 2018. If the Project proceeds, it will be the largest pipeline system to be constructed and operated in Canada's north.
