SemGroup recently announced it is converting a portion of the White Cliffs Pipeline system to NGL Y-grade service connecting the DJ Basin to Cushing, Oklahoma. To complete the project, DCP Midstream will construct a 25 mile pipeline in the DJ Basin, connecting its system to White Cliffs, and SemGroup will construct a 12 mile extension of White Cliffs Pipeline south of Cushing to interconnect with Southern Hills Pipeline. The project is backstopped by 10-year agreements with DCP Midstream, LP and its affiliate DCP Southern Hills Pipeline, LLC. SemGroup owns 51% of White Cliffs Pipeline and is the operator. DCP owns 66% of Southern Hills Pipeline and is the operator.
