More than 200,000 gallons of oil spilled from the Keystone Pipeline near Amherst, South Dakota late last week, yet further expansion of the pipeline’s bigger brother, Keystone XL, was approved by the state of Nebraska on Monday.

TransCanada, the company that owns both pipelines, shut down the Keystone Pipeline last Thursday morning at 6 am after detecting a drop in pressure, indicating a leak. About 5,000 barrels of oil spilled onto privately owned land roughly 200 miles north of Sioux Falls, South Dakota. The company is still investigating the cause of the pipeline’s rupture.

Just three days after the oil spill, Nebraska’s Public Service Commission decided the fate of the Keystone XL pipeline’s route through Nebraska. Caving to pressure from Nebraska’s conservative legislators as well as industry and labor groups, the five-person commission agreed to allow the pipeline to cross through Nebraska. However, the pipeline must follow an alternative route. While the pipeline will enter and exit the state in the originally proposed locations, the commission will require its route to follow an existing pipeline’s path. This change will make responding to leaks more efficient according to regulators.

The U.S. Environmental Protection Agency reports that 10-25 million gallons of oil spill each year. Not only do oil spills destroy habitat, kill plants and animals, and compromise agriculture, they also threaten public heath by contaminating drinking water and degrading air quality.

Thursday’s oil spill came exactly one year after Native American protesters were sprayed with water cannons in 23 degree weather as they attempted to stop the construction of the Dakota Access Pipeline through North Dakota, citing oil spills as a primary concern.

 

Nearly 140,000 gallons of oil spill from Iowa pipeline

Nearly 140,000 gallons of diesel fuel erupted from a broken pipeline onto an Iowa farm earlier this week.

The pipeline, located in north-central Worth County, was first discovered to have ruptured on Wednesday morning. Since then, clean up crews have managed to remove roughly 18 percent of the petroleum product despite high winds and heavy snowfall, according to a Thursday morning interview with Iowa Department of Natural Resources spokesperson Jeff Vansteenburg. Vansteenburg said that the diesel fuel and contaminated snow are being taken to a facility in Minneapolis, Minnesota while the remaining contaminated soil will be moved to a landfill near Clear Lake, Iowa.

Vansteenburg reported that the diesel fuel did not reach the nearby Willow Creek and wildlife reserve. The cause of the leak is still under investigation.

Magellan Midstream Partners, an Oklahoma-based company, owns the pipeline, which stretches through Illinois, Iowa, Minnesota, North Dakota, South Dakota and Wisconsin. Last October, another pipeline operated by Magellen Midstream Partners ruptured and released anhydrous ammonia, resulting in the evacuation of 23 homes and the death of one person near Decatur, Nebraska. The company was also fined over $45,000 by the U.S. Environmental Protection Agency in 2010 after roughly 5,000 gallons of diesel fuel leaked into a Milford, Iowa creek.

The Worth County spill is the largest diesel fuel spill since 2010 according to the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration. Since 2010, 807 spills have been reported to the administration causing an estimated $342 million in property damages and spewing 3 million gallons of refined oil products into the environment.

President Trump signed executive actions on Tuesday reviving the Keystone XL and Dakota Access pipelines. Ed Fallon is the director of Bold Iowa, an organization fighting the Dakota Access and Keystone XL oil pipeline projects. Fallon said, “We’ve been saying all along it’s not a question of if a pipeline will leak, it’s a question of when and where and how bad it will be.”

The Pipeline and Hazardous Materials Safety Administration (PHMSA) is charged with regulating pipelines in the U.S. Inside Energy reported last year that the agency is underfunded and understaffed. It read,

“According to PHMSA, the agency has 533 inspectors on its payroll. That works out to around one inspector for every 5,000 miles of pipe. A government audit in October [2016] found that that PHMSA is behind on implementing new rules. It has 41 mandates and recommendations related to pipeline safety that await rulemaking.”

A 2016 report by Inside Energy provides a map of all the oil pipeline spills reported since 2010.

BP Oil Spill in Lake Michigan

Workers at the Whiting refinery reported an oil sheen on the water this past Monday.

Mike Beslow, the EPA’s emergency response coordinator, said there appeared to be no negative effects on Lake Michigan, the source of drinking water for 7 million people in Chicago and the suburbs.

Researchers at Iowa State University, Columbia University and Louisiana State University are working together to create an environmentally friendly substance for cleaning up oil spills.

Current chemicals used to clean oil spills are toxic to marine life.

This research is in its beginning stages. Those involved in the project don’t expect to see their work turned into a commercial project for at least a decade.
