The land portion of the IGC Project is proposed to run approximately 34 miles (54 kilometres) from Williams’ Northwest Pipeline’s Canadian gas interconnect at Sumas, Washington to the shoreline in the Birch Bay/Custer, Washington area.
Early in the routing process, landowners along the proposed route are contacted to request permission to survey and stake the area for environmental, engineering and construction evaluations. Our goal is for every landowner to understand all of the proposed design and safety features of the proposed pipeline before construction, including the underground depth, pipe size, temporary and permanent width of the easement and above-ground equipment.
From digging trenches to laying pipe to final testing, pipeline construction is a complex process that involves many steps. Many people are surprised by the number of people and amount of equipment required to build a pipeline. Pipeline construction looks much like a moving assembly line. As one crew completes its work, the next crew will move into position to complete its piece of the construction process. It includes many components.
