The Transportation Safety Board of Canada and the National Energy Board are investigating a spill at an Enbridge storage facility in Strathcona County.
Enbridge said Monday that crews were responding to a leak just before 4 p.m., synthetic crude oil spilled from a tank valve at the company’s Edmonton Terminal.
Crews were deployed Monday to contain the spill and recover the product – officials said some of the product had flowed off of the property and onto a nearby industry site through a drainage ditch, before spilling into a creek.
On Monday, officials said that spill in the creek had been contained.
NEB officials are also on the scene.
“Leaks from these types of tanks are very rare, and leaks that extend beyond a tank and beyond a berm, and a berm is like a small hill that is around the storage facilities to ensure oil doesn’t get out, is also very rare,” NEB spokesperson Tom Neufeld said.
Enbridge said on Tuesday that almost all of the released product had been contained, and had been recovered, along with a sheen seen on spring runoff.
At last word, it wasn’t clear how much product spilled.
Officials said this case is the second time this year the TSB has investigated an oil spill at an Enbridge facility, back in February, more than 960,000 litres of oil leaked from a pipeline in the same area.
The Alberta Wilderness Association said state-of-the-art equipment that’s supposed to detect spills isn’t working well enough.
“We need to be able to count more on the detection equipment that is promised by operators when they put in a pipeline, that that will be the fastest and best way to detect spills, rather than people just discovering it,” Carolyn Campbell with the Alberta Wilderness Association said.
The NEB and TSB are still investigating.
