According to Energy Transfer Partners, work on the Dakota Access pipeline section in South Dakota is nearly complete.
In a report filed Friday to the South Dakota Public Utilities Commission, Energy Transfer stated that 100 percent of the South Dakota section of the four-state pipeline is underground. This includes underneath waterways such as the Big Sioux River.
The pump station in Redfield is 85 percent complete, according to the filed report, and the company is currently working on erosion control and testing.
The 272-mile section in South Dakota is part of a 1,170-mile oil pipeline that will travel through North Dakota, South Dakota, Iowa, and Illinois. It has spurred national controversy as thousands of protestors in North Dakota and other states have stood against its construction saying it would ruin waterways and destroy sacred sites.
