July 4, 1977 – After 214 days of public hearings, the Board releases its Reasons for Decision on the Northern Gas Pipeline Applications. Citing environmental concerns, the Board denied separate applications from Foothills Pipe Lines and Canadian Arctic Gas Pipeline to build a gas pipeline through the Mackenzie Valley.
