VANCOUVER (NEWS 1130) – A natural gas pipeline that runs from northeastern BC to the Chicago area has been shut down while its operator disposes of dangerous hydrogen sulphide gas that got into the system.

Alliance Pipeline says the major Canada-to-US line will be closed for an indeterminate amount of time as it deals with the gas, which is poisonous, corrosive, flammable and smells like rotten eggs.

The company did not say how much hydrogen sulphide entered the pipeline, only that the amount exceeded its standards.

The Alliance Pipeline — jointly owned by an affiliate of pipeline giant Enbridge and Calgary-based Veresen — runs carries 1.6 billion cubic feet of natural gas a day to the US.
