A natural gas pipeline that runs from northeastern British Columbia to the Chicago area shut down while its operator disposes of dangerous hydrogen sulphide gas that got into the system.
The major Canada-to-US line shut down for an indeterminate amount of time as Alliance Pipeline 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 U.S.
From oil to molasses and everything in between, pipelines have come under fire for various forms of safety issues.
An Plains All American Pipeline in California leaked from 101,000 to potentially 143,000 gallons of oil in May.
Meanwhile, a faulty pipeline caused a massive molasses spill in Honolulu Harbor two years ago, and now a U.S. shipping company will pay Hawaii more than $15 million to reimburse the state for the cost of cleanup and restoration. About 1,400 tons of brown, sticky liquid leaked into the harbor in September, 2013, from a faulty molasses-loading pipeline used to load it onto ships operated by Matson Navigation Company, an international ocean transport company.
In early July, a natural gas pipeline explosion and fire in White Deer, TX, located on the Panhandle left four workers hurt, including two in critical condition. The incident occurred in White Deer, about 35 miles northeast of Amarillo.
An explosion in rural DeWitt County, TX, in June shook nearby homes and illuminated the horizon. A 42-inch Energy Transfer pipeline containing natural gas ruptured. At the time of the explosion, the flames shot up to about 100 feet in the air.
In May, there was a water leak in North Dakota as a pipeline spill caused about 220,000 gallons of produced water to leak in a field near Mandaree on the Fort Berthold Indian Reservation.
