CALGARY – A major cross-border natural gas pipeline is expected to restart on Thursday, nearly a week after it was forced to close because dangerous gas mistakenly got into the system.
Alliance Pipeline has been burning off the hydrogen sulphide-tainted gas in southeastern Saskatchewan since the weekend in order to safely dispose of it.

Alliance says the flaring near Arolca and Alameda is expected to wrap up on Wednesday.
Natural gas processor and transporter Keyera Corp. (TSX:KEY) said Friday that the toxic gas got into the Alliance pipeline after a “brief operational upset” at its Simonette gas plant in northwestern Alberta two days earlier.
Both Keyera and Alliance have said once they line is back up and running, they’ll be able to analyze data and figure out what went wrong.
The Alliance Pipeline runs from northeastern B.C. to the Chicago area and ships about 1.6 billion cubic feet of natural gas a day.
