Environmentalists were outraged but not at all surprised to learn Thursday that the Keystone pipeline sprung yet another massive leak, this time spilling 383,000 gallons of crude oil in North Dakota.\u0022I wish I could say I was shocked, but a major spill from the Keystone pipeline is exactly what multiple experts predicted would happen,\u0022 Greenpeace USA senior research specialist Tim Donaghy said in a statement. \u0022In fact, this is the fourth significant spill from the Keystone pipeline in less than ten years of operation. History has shown us time and again that there is no safe way to transport fossil fuels, and pipelines are no exception.\u0022\u0022We\u0026#039;ve always said it\u0026#039;s not a question of whether a pipeline will spill, but when, and once again TC Energy has made our case for us.\u0022 —Catherine Collentine, Sierra ClubAs 350.org founder Bill McKibben tweeted in response to the leak, \u0022It happens over and over and over and over and over.\u0022The latest Keystone spill was first detected Tuesday night by TC Energy, the pipeline\u0026#039;s owner, and the extent of the damage to the surrounding areas is not yet known to the public. According to Greenpeace, the leak \u0022is already the eighth-largest pipeline oil spill of the last decade.\u0022The Keystone pipeline just spilled AGAIN** — and is now the 8th largest pipeline oil spill in the past decade. **Brought to you by the corporation that wants to build the much larger #KXL pipeline and have it cut right through the Midwest... https://t.co/gHXxIC12Sw #NoKXL\u0026mdash; Greenpeace USA (@greenpeaceusa) October 31, 2019 Brent Nelson, emergency manager for Walsh County, North Dakota, told the local\u0026nbsp;Grand Forks Herald that the cleanup process could take months.\u0022The roads around the spill area have been closed to assist with the cleanup,\u0022 the Herald reported. \u0022Walsh County Sheriff Ronald Jurgens asks the public to avoid the area so the cleanup process can proceed. On-site security will stop and fine any driver ignoring the closed road signs.\u0022TC Energy, previously known as TransCanada, denied that the spill had any impact on drinking water, a claim that was met with skepticism.Keystone Pipeline leak spills oil in northeastern North Dakota Corp says the oil hasn’t contaminated any drinking water \u0026amp; they’re cleaning it up but anyone who drives to the site will be fined by their security so who knows what’s going on. #NOKXL https://t.co/7H6Dcz4bsm— Ruth Hopkins (@RuthH_Hopkins) October 31, 2019Catherine Collentine, associate director of Sierra Club\u0026#039;s Beyond Dirty Fuels initiative, said \u0022this is not the first time this pipeline has spilled toxic tar sands, and it won\u0026#039;t be the last.\u0022\u0022We\u0026#039;ve always said it\u0026#039;s not a question of whether a pipeline will spill, but when,\u0022 said Collentine, \u0022and once again TC Energy has made our case for us.\u0022Keystone\u0026#039;s leak in North Dakota was detected just hours after the U.S. State Department held a public hearing in Billings, Montana to solicit comments on the department\u0026#039;s new analysis (pdf) of the potential environmental impact of the Keystone XL project.The Trump administration has worked hard to approve and accelerate the project over the protests and legal challenges of indigenous rights organizations and green groups.Joye Braun, frontline community organizer with the Indigenous Environmental Network, said the State Department meeting on Keystone XL \u0022seemed more like an industry showcase rather than public comment hearing.\u0022\u0022We stand firm in opposing this project as the latest spill is further evidence of just how dangerous pipelines are,\u0022 said Braun.
