The company will hold the open season for the pipeline from 19 November to 17 December 2012.
The under construction NGL pipeline will be used to transport unfractionated NGLs from the Bakken Shale in the Williston Basin to an interconnection with ONEOK’s 50% owned Overland Pass Pipeline in northern Colorado.
ONEOK’s NGL pipeline is expected to begin operations in the first quarter of 2013.
The company has already announced expanding the capacity of the pipeline which is scheduled for completion in the third quarter of 2014.
Open season process allows potential shippers to book the pipeline for long-term transportation contracts and ONEOK will in return provide priority transportation service for both the initial and expanded capacity.
