A $6 million benefit agreement with the Nisga'a Nation to build a gas pipeline through its territory is the first of a series of deals that will share benefits of liquefied natural gas development with B.C. First Nations, Aboriginal Relations Minister John Rustad says. Rustad and Natural Gas Development Minister Rich Coleman signed the agreement Thursday with Nisga'a Nation President Mitchell Stevens to accommodate a pipeline through Nisga'a territory to an LNG export facility proposed near Prince Rupert.
