The B.C. Energy Regulator (BCER) is investigating after Coastal GasLink (CGL) reported two spills of clay lubricant while it was tunnelling under the Morice River to build a natural gas pipeline through northern British Columbia. The area around the Morice River has for years been the site of conflict between Wet'suwet'en hereditary chiefs and supporters, and CGL, its workers and the RCMP.
