CUSHING, Okla. (AP) — New pipeline projects are expanding the size of an Oklahoma crude oil hub that is already one of the most important oil storage facilities in the world.

One new pipeline is in operation at the hub in Cushing, another is almost complete and a new project was announced earlier this month when Tulsa-based NGL Energy Partners revealed plans for the Grand Mesa Pipeline, a joint venture with Rimrock Midstream LLC, the Tulsa World reported Saturday (http://bit.ly/1qSnvYR ).
