North Dakota, long known for its cattle ranches and open spaces, has recently become one of the oil and gas industry’s most prized (and profitable) possessions, thanks to theย advent of fracking. However, the price of oil and gas industry development is paid in destruction to the environment and strains to the regulatory framework meant to protect the public from a reckless industry, as Tesoroโs massive oil spillย attests.
Documents from an openย records request by Greenpeaceย have uncovered that Tesoro, a fracking giant based in Sanย Antonio:
Possibly knew their pipeline was dangerouslyย weak
Tesoro ran tests on the pipeline that ruptured more than 2 weeks before the spill wasย discovered.
A robot, known as a โsmart pig,โย detected weaknessesย in the pipeline onย September 10 and 11. Tesoro claims that they did not have ample time to digest the data before the spill, butย Tesoro employeesย on the ground tell a different story. Furthermore, once the pipeline spill was discovered, Tesoro dispatched crews to check two other sites on the pipeline for leaks, indicating they were aware of potential fail points in the pipeline. See the documents uncovered byย Greenpeace here.
Did not report the spill correctly orย promptly
Tesoro corp is not saying how long the pipeline has been leaking. The hole in the line was about aย quarter inch in diameter, and it would have taken some time for 20,600 barrels of oil to foul a wheat field the size of seven football fields. However, when the spill was finally reported to the authorities, the quarter inch hole had already released hundreds of thousands of gallons, enough to make the Teoro spill the largest in North Dakota history. When Tesoro did report the spill, it didย not report it through the proper channels. This caused confusion with state officials, and helped keep the spill out of the public eye forย weeks.
Still does not know how much oil wasย spilled
Tesoro has revised the amount they admit spilling multiple times since the oil spill became public, increasing the amount significantly each time. These revisions are not a surprise given that Tesoro is using anย inaccurate and backward system for measuring the oil lost, that experts say doesnโt โadd upโ. Their current method is to roughly estimate the amount of oil it would take to cause the evident destruction, rather than measuring the amount that should have arrived at the other end of theย pipeline.
Got help from regulators to โkeep the problem in Northย Dakotaโ
As with other areas that have faced oil industry invasion underwritten by fracking, North Dakotaโs oil infrastructure has far outpaced the stateโs ability to regulate it. Fun fact, Theย Pipeline and Hazardous Materials Safety Administrationย (PHMSA), the federal body in charge of Tesoroโs pipeline, has only 135 federal inspectors overseeing 2.6 million miles of pipeline, which means each inspector is responsible for almost enough pipe to circle theย Earth.
In North Dakota, the Department of Health oversees environmental crimes such as Tesoroโs spill. Documents obtained by Greenpeace show a close relationship between regulators for the Department of Health, the North Dakota body responsible for overseeing Tesoro, and the company itself. Regulators for North Dakotaโs DOHย helped Tesoro call the policeย on people investigating the spill, and helped Tesoroย โkeep the problem in North Dakota,โย by trying to contain leakedย information.
The huge boom in oil and gas production has been driven byย fracking, a controversial drilling process that has made North Dakota one of the top producing oil fields in the world. In August North Dakota produced more thanย 911,000 barrels of oil per day. The Tesoro spill belies the danger of under-regulated and dangerous pipelines, like the proposedย Keystone XL. These pipelines enrich the few, while the risks are borne by the unfortunate people in theirย path.
