Magellan Midstream Partners, L.P. and Plains All American Pipeline, L.P. announced that they have formed Saddlehorn Pipeline Company, a 50/50 limited liability company, to construct, own and operate the Saddlehorn pipeline, an approximately 550-mile pipeline that will transport various grades of crude oil from the DJ Basin, and potentially the broader Rocky Mountain area resource plays, to storage facilities in Cushing, OK owned by Magellan and Plains. An extension to Carr, CO is also under consideration for connection to existing crude oil assets owned by Plains in that region.
