The Proposed Project

• Westcoast Energy Inc. (Westcoast) is proposing the Sunrise Expansion Program in British Columbia. This project involves building approximately 137 kilometres (km) of 42-inch diameter natural gas pipeline, extending southwest of Chetwynd to the Canada-United States border near Sumas, British Columbia. 
• Westcoast plans to route the CS-8B to CS9 pipeline loop through Seabird Island Band reserve lands. These reserve lands are federal lands, as defined in section 2 of the Impact Assessment Act.
• For the works occurring on Seabird Island Band reserve lands, the proponent has applied to Environment and Climate Change Canada for a Species at Risk Act permit under section 73(3).
