Boardwalk Pipeline and BPHC have contributed a total of $79 million to the project as of December 31, 2013.

On October 1, 2012, a joint venture between Boardwalk Pipeline and BPHC acquired Boardwalk Louisiana Midstream LLC, a company that provides salt dome storage, pipeline transportation, fractionation and brine supply services, from PL Logistics LLC for approximately $620 million.
