Workers from the state-owned pipeline responded to the spill at the Sumas Pump Station in Abbotsford, B C, after an alarm went off at the pipeline control center early Saturday, the company said in a release posted on its website. The Trans Mountain pipeline has already spilled more than 80 times since it began operating.
Trans Mountain says oil is once again flowing through its pipeline following a spill Saturday near Abbotsford B.C.
The Trans Mountain expansion project would almost the 300,000 barrels it now carries daily from Alberta to a terminal in Burnaby, B.C.
"The big threat is the cumulative effects", Dalton Silver chief of Sumas First Nation told Global News.
Trans Mountain's initial investigation concluded the spill was the result of a 1-inch (2.54-centimeter) fitting on a piece of pipe connected to the mainline.
Oil spills have also remained a persistent worry for pipeline opponents.
"B.C. will insist the federal regulator ensures Trans Mountain takes full responsibility for negative environmental or other impacts", Environment Minister George Heyman said.
"The site has permanent groundwater monitoring in place and air monitoring continues". "There are a number of steps and procedures that need to happen before we can safely restart the pipeline".
He said in a statement Sunday that it's the fourth time in 15 years that there has been a spill from the pipeline on their land.
"We think of these as one-time events, but when you think about the life of a pipeline and you add up all these spills into the marine ecosystem and land ecosystems.it's really catastrophic for ecosystems", McCartney added.
The Trans Mountain pipeline in British Columbia resumed operation on Sunday after an oil spill occurred over the weekend.
The spill has been contained, and crews are working to clean up the site.
The Canadian government bought the Trans Mountain pipeline from Kinder Morgan Canada in 2018, as it faced regulatory and legal hurdles to expansion.
