Despite running 18 months behind schedule, Sunoco/Energy Transfer believes it will start shipping natural gas liquid along a hybrid pipeline in Chester and Delaware counties by the end of the year, according to Daily Local News.
The company plans to connect three different sized pipes along a 350-mile path from Marcellus shale deposits in West Virginia, Ohio and Pennsylvania to the former Marcus Hook, Delaware County Refinery. The original plans called for the construction of a 16-inch (Mariner East 2X pipeline) and 20-inch (Mariner East 2 pipeline) to follow a path along an existing 1930s easement. However, the new plans have been updated and require a mishmash of 20-inch, 16-inch and an existing 12-inch pipe, which would partially take a new route.
Sunoco is referring to the hybrid pipeline as Mariner East 2.
