Coastal GasLink has been issued stop work orders on a stretch of pipeline construction for the second time in just over a week, the latest in a pattern of environmental violations for polluting sensitive waterways. The pipeline project crosses about 625 lakes, rivers, creeks, wetlands, and streams in northern B.C. On Tuesday, the BC Environmental Assessment Office Compliance and Enforcement Branch said it had issued four stop work orders to Coastal GasLink late last week because erosion and sediment were negatively impacting the upper Anzac River watershed, about 130 kilometres northeast of Prince George.
