Keystone’s North Dakota spill affected 10 times more land than first thought

Share

A crude oil spill on the Canadian-owned Keystone pipeline that runs from Alberta to the U.S. Gulf Coast appears to have affected almost 10 times more land in northeastern North Dakota than originally reported.

Calgary-based TC Energy, formerly known as TransCanada, first estimated that the Oct. 29 pipeline rupture near the town of Edinburg had affected 2,090 square metres of land.

North Dakota state regulators now say the leak affected 19,426 square metres.

The reassessment comes a little more than a week after TC Energy officials said on Nov. 10 that the pipeline was up and running again, with the approval of U.S. authorities.

North Dakota environmental scientist Bill Suess told Associated Press that TC Energy did not have an estimate of the land affected.

Suess said it included some wetlands but not any sources of drinking water.

Excavation equipment was used to search for the oil leak close to the Keystone oil pipeline near St. Charles, Mo. in February.

The director of North Dakota’s division of water quality, Karl Rockeman, told the U.S.-based website The Hill that earlier estimates were based on visual information.

Further inspection, he said, had resulted is what he called a more accurate assessment.

Rockeman told The Hill he thought the cleanup is, “making good progress.”

A TC Energy spokesman said in a statement the volume of initial figure of 383,000 gallons of oil that was spilled had not changed.

The $7.8 billion pipeline went into operation in 2011.

It runs from Alberta through Saskatchewan and Manitoba and then numerous U.S. states that include North Dakota, South Dakota, Nebraska, Kansas, Missouri, Oklahoma and Texas.

The Oct. 29 spill was the third on the pipeline route in less than three years and the fourth in nine years.

The cause has not yet been established.

When operating at full capacity, the pipeline carries 590,000 barrels a day.

    I am just not willing to read more of this criminal actions. It again and again shows, that promises of saftey are not kept, when it comes to technical structures of all kind.

    Many churches in Europe were built in the 11th and 12th century, they have to be repaired, but they still stand.
    Or look at Stonehenge it was built between 3000 till 15oo before Christ.

    And our generation?? Simply incapable.

    Greed, destruction, corruption, as usual, prevails. Is it any wonder true Christians believe that only Jesus Christ will ultimately prevail and give us a new earth after we have destroyed ours?
