Update on AltaGas' Energy Export and Northeast BC Strategy

In connection with AltaGas' capital growth opportunities, AltaGas continues to make significant progress on its energy export and northeast British Columbia gas strategy. As previously announced, AltaGas has begun the formal environmental review process for the proposed Ridley Island Propane Export Terminal, filed an application with the National Energy Board for a 25 year propane export license and entered into a memorandum of understanding with Astomos Energy Corporation for the sale and purchase of liquefied petroleum gas from such terminal. AltaGas is also progressing with developing a liquids separation and handling facility, the North Pine Project, to be located 45 km northwest of Fort St. John, British Columbia. The North Pine Project will be connected to AltaGas' existing infrastructure in the region, including the proposed Ridley Island Propane Export Terminal, and will serve producers in the Montney region. AltaGas expects to reach final investment decisions in 2016 for both the North Pine Project and the Ridley Island Propane Export Terminal.
