The expansion project, which is a looping of the existing crude oil pipeline from Platteville, Colorado, to Cushing, Oklahoma, is slated to be fully operational in August 2014.
The project will enable the company to help meet the growing demand for midstream services by offering long-haul transportation from the Denver Julesburg Basin, White Cliffs Pipeline said in a statement.
Once operational, the White Cliffs pipeline capacity will increase from 76,000 barrels per day to approximately 150,000 barrels per day.
Rose Rock Midstream will continue to operate the White Cliffs Pipeline upon completion of the expansion project.
White Cliffs Pipeline is a partially owned subsidiary of Rose Rock Midstream, Plains All American Pipeline, Western Gas Partners and Noble Energy.
