MarkWest Energy yesterday announced an open season for a “little” ethane pipeline in Pennsylvania. The little pipeline, which we now have a name for–MarkWest Liberty Ethane Pipeline–will run from Majorsville, PA to Houston, PA, about 30 miles. It is a pipeline to other pipelines. The MarkWest plant in Houston will provide access for the incoming ethane to be pipelined out of the area via the Mariner West pipeline (to Sarnia, Canada, going operational later this month), the Mariner East pipeline to the Marcus Hook refinery near Philadelphia (not ready until 2015), and the ATEX ethane pipeline to the Gulf Coast (ready sometime in 1Q14).
