The National Energy Board has scheduled public hearings on Kinder Morgan's proposed expansion of the Trans Mountain Pipeline system, which would triple its capacity to ship crude oil between Strathcona County, near Edmonton, and Burnaby, B.C.

The board will hear aboriginal traditional evidence in August and September. An oral hearing will begin next January.

More than 400 intervener and more than 1,200 commentators are expected to take part in the hearings, which will look at 12 issues.

They include potential environmental and socio-economic effects, as well as potential impacts on aboriginal interests, landowners and land use.

The project would add to the current pipeline network that exists in Alberta and B.C.

The final report is to be presented by July 2015.
