AltaGas Ltd. received the Alberta Court of Appeal decision dismissing the third party appeal of the decision of the Energy Resources Conservation Board (ERCB) which approved the Harmattan Co-stream project. AltaGas originally received the ERCB approval of the project on December 7, 2010.
In early January 2011, two of the initial interveners in AltaGas' ERCB application filed notices of motion for leave to appeal the ERCB decision to approve the Co-stream Project at the Court of Appeal of Alberta. In late January, one of those parties filed an application with the ERCB for a Review and Variance of the ERCB Decision. The application was dismissed by the ERCB on May 27, 2011. The leave to appeal applications were heard on June 8, 2011 and the appealing parties were granted leave to appeal on August 8, 2011. The appealing parties filed their notices of appeal with the Alberta Court of Appeal on September 7, 2011, and the hearing was held on April 5, 2012.
