Third oil spill fuels calls for Alberta pipeline review
“About 230,000 litres of heavy crude oil spilled from a pumping station on an Enbridge Inc. pipeline onto farmland, Alberta’s oil and gas regulator, the Energy Resources Conservation Board (ERCB), said Tuesday.
The regulator said 1,450 barrels of oil spilled from a pumping station on Enbridge’s Athabasca pipeline, 24 kilometres from Elk Point, Alta., a small town roughly 200 kilometres northeast of Edmonton. That pipeline, briefly shut down but then restarted Tuesday, connects the oil sands with Hardisty, Canada’s most important crude oil hub. The spill comes while crews are still working to clean up two other large leaks in Alberta, nearly 800,000 litres of oil from a Pace Oil & Gas Ltd. well about 200 kilometres from the Northwest Territories border, and 160,000 to 480,000 litres from a Plains Midstream Canada pipeline that ruptured beneath the Red Deer River.
Environmental groups are now seizing on the confluence of accidents, which includes another massive spill from a Plains pipe last year, to call for an expansive look at pipeline safety in Alberta.”
“Given the significant number of pipeline spills in recent months, Alberta should conduct a review of the integrity of Alberta’s pipeline system,” said Simon Dyer, policy director with Alberta’s the Pembina Institute. “Pipeline spills are inevitable but the risks can be reduced through stronger regulation and practices.”
ZetaTalk about Stretch Zone Accidents
Stretch zone incidents - where rock pulls apart or snaps, creating booms and vibrations and hums, dropping bridges that lose their moorings or snapping gas and water mains, or creating sinkholes or crevasses - are not considered earthquake incidents. Quakes occur when rock borders slide along each other or push under one another, creating a jolt or a series of jolts. Stretch zone accidents only happen when major plate movement is occurring, and are usually silent so do not get the attention that jolting earthquakes get. A bridge slips off its mooring and is attributed to heavy trucks or poor construction. A sinkhole appears and is attributed to ground water erosion. A building implodes and is attributed to settling, even though the building may have been there for centuries.
