"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 (Figure 1). The Dakota Access Pipeline is projected to carry 470,000 barrels per day, although its capacity could reach 570,000 barrels per day."
