According to Enlink Midstream Partners LP, in an SEC filing:

The Phase I expansion added 130-miles of 12-inch diameter pipeline to our existing 440-mile Cajun-Sibon NGL pipeline system, connecting Mont Belvieu to our Eunice fractionator. Phase I of the pipeline currently has a capacity of 70,000 Bbls/d for raw make NGLs. The Phase I NGL pipeline extension originates from interconnects with major Mont Belvieu supply pipelines and provides connections for NGLs from the Permian Basin, Barnett Shale, Eagle Ford and other areas to our NGL fractionation facilities and key NGL markets in south Louisiana. Phase I is anchored by a five-year ethane sales agreement with Williams Olefins, a subsidiary of the Williams Companies and a five year natural gasoline sales agreement with another company. We have entered into yearly sales agreements for all other purity products.

The Cajun-Sibon expansion project consists of a 139-mile, 12-inch pipeline that will extend Crosstex’s existing 440-mile Cajun-Sibon NGL pipeline system, connecting its Eunice fractionation facility in south central Louisiana to Mont Belvieu supply lines in East Texas.

According to an EnLink press release:

The expanded Cajun-Sibon system connects EnLink Midstream’s Eunice fractionator in South Louisiana to Mt. Belvieu supply pipelines in East Texas, improving the reliability and diversity of NGL supply to the region’s petrochemical and refining markets. Phase II of the Cajun-Sibon project, which is supported by long term, fee-based ethane and propane sales agreements with a major petrochemical company in the region.

Phase III Expansion

A capacity expansion appears to have been proposed in 2018 during a binding season announcement, but there is no further evidence that the project moved forward. As of 2022 it is considered cancelled. The expansion would have been operational by the second quarter of 2019, and the additional capacity was expected to expand delivery to the Gulf Coast petrochemical industry.
