Sunoco Logistics’ Mariner East 1 pipeline that runs from southwest Pennsylvania all the way to a refinery near Philadelphia continues to make progress on beginning to flow both propane and ethane. We’ve written numerous stories on the project (see the list here). Almost all of the pipeline is already in the ground–has been for decades–and will be repurposed from transporting oil to transporting natural gas liquids. The current situation is this: Sunoco Logistics is still fighting a legal battle to build 18 pump and 17 valve stations in 31 municipalities along the route. We don’t have any update on the legal battle, but we do have an update on testing of the pipeline. In October we told you that a section of the pipeline near Lebanon, PA was being tested (see Mariner East NGL Pipeline Begins Tests in Lebanon, PA). Good news, the test is complete and the pipeline, in that area, passed with flying colors…
