The proposed expansion will primarily consist of approximately 30 miles of new pipe and horsepower addition at existing compressor stations at various locations in Pennsylvania and New Jersey, in addition to existing facility modifications along its mainline. The capital cost of the project is estimated to be approximately $610 million.
Most of the new pipe will be installed either entirely within or parallel to existing pipeline and utility rights-of-way. All other compression-related activities will be performed entirely within existing compressor station facilities. If approved, compressor station construction would begin in the fall of 2014 with pipeline construction following in the spring of 2015.
