"Recent growth of domestic crude oil production has resulted in an unprecedented expansion of the United States' oil pipeline network. One of the largest domestic oil pipelines currently in development is the Dakota Access Pipeline, a 30-inch diameter, 1,172-mile project that would carry crude oil produced in northwest North Dakota to southern Illinois. The Dakota Access Pipeline is projected to carry 470,000 barrels per day, although its capacity could reach 570,000 barrels per day. [...] The federal government does not have jurisdiction over the siting of domestic oil pipelines like the Dakota Access Pipeline. Instead, authorization for the overall route must be granted by individual states, each of which may impose its own requirements and procedures. The Dakota Access Pipeline developer, Energy Transfer Partners, was granted siting approval from state utility regulators in South Dakota and Illinois in 2015, and from North Dakota and Iowa early in 2016."
