<P> The company estimated the pipeline would cost $3.78 billion, of which $1.4 billion would be invested in the North Dakota portion, $820 million in the South Dakota portion, $1.04 billion in the Iowa portion, and $516 million in the Illinois portion . Of this, $189 million would be paid to landowners . </P> <P> Energy Transfer Partners has estimated that the pipeline would create up to 40 permanent jobs and 8,200 to 12,000 temporary jobs, of which between 12 and 15 permanent jobs and from 2,000 to 4,000 temporary jobs will be in Iowa . The $1.35 billion capital investment in Iowa was projected to generate $33 million sales tax in Iowa during construction and $30 million property tax in 2017 . According to the Des Moines Register, Energy Transfer hired "Strategic Economics Group" in West Des Moines to prepare this analysis . Dave Swenson, an Iowa State University economics professor, said that "a strong fraction of work will accumulate to out - of - state employers who will bring in their skilled labor and then subcontract what they can along the way" to local concerns . </P> <P> The ETP desires the pipeline to provide an outlet for oil to be transferred across the country and then sold to international countries and corporations . Dakota Access, LLC's planning applications argued that the pipeline improves the overall safety to the public, would help the US to attain energy independence, and is a more reliable and safer method of transport to refineries than rail or road . Proponents have argued that the pipeline will free up railroads, which will allow farmers to ship more Midwest grain . About 70% of Bakken oil is transported by rail because of pipeline limitations . As of July 2014 Bakken shale oil was transported through nine Iowa counties exclusively via three freight trains per week . As of June 2014, 32 trains per week carrying Bakken oil traveled through Jo Daviess County in northwestern Illinois . </P> <P> Evaluating which is best for the cost of transport and human and environmental safety is difficult and involves a variety of factors . Rail offers greater flexibility and adaptability and has had fewer spill volume per Billion - Ton - Miles, but costs significantly more than pipeline transportation and, similar to pipeline, still requires additional investment . </P>
