Belvieu Alternative for NGLs Y-Grade Pipeline (BANGL) was a proposed natural gas liquids (NGL) pipeline in Texas, United States.[1] In May 2020, the project promoters announced that they were cancelling the project.[2]


The pipeline was planned to run from the Permian Basin to the Sweeny, Texas area.[1]

The BANGL pipeline was planned to move Y-grade NGL from the Permian Basin to the NGL fractionation hub in Sweeny, Texas, with a planned initial capacity of approximately 500,000 barrels per day. It was expected to be operational in late 2021.[1]

Marathon announced in May 2020 that it was cancelling the project due to the collapse in oil prices and said that instead it would be focusing on expanding capacity on its existing pipelines. A fractionation capacity and export facility associated with the BANGL project was also cancelled. Reuters reported Marathon's CEO Michael Hennigan explaining the reason for the cancellation: "We are still committed to an NGL solution. It just won’t be the original scope that we had envisioned early on. We wanted to not commit to that full scope until we were really sure that the volume commitments would be there (and) with what’s happening in the market, the volume commitments are slower."[2]

In August 2020, a joint venture was announced among MPLX LP, WhiteWater Midstream, and West Texas Gas to accomplish the goals of the original BANGL Pipeline, but using existing infrastructure with limited initial construction, and allowing for potential future expansions. This joint venture, later identified as BANGL LLC, included multiple capacity arrangements from Orla to Sweeny, Texas, USA that included the EPIC NGL Pipeline.[3] Commercial operations began in the fourth quarter of 2021, and in January 2022, Rattler Midstream LP was announced as a fourth parter of the BANGL LLC joint venture.[4]
