ETP's filing, dated October 19, amends the tariff on its Sunoco Pipeline affiliate's Mariner East 1 and 2 pipelines carrying NGLs from the Utica/Marcellus shale plays to its Marcus Hook, Pennsylvania, terminal for export.
The existing 70,000 b/d Mariner East 1 line transports ethane and propane from Houston, Pennsylvania, to Marcus Hook. Mariner East 2, which has a nameplate capacity of 275,000 b/d, will move propane and butane from Scio, Ohio, through Houston, Pennsylvania, to Marcus Hook.
Under the new tariff, uncommitted shippers for propane, butane and C3+ will pay 1 cent/b less than committed shippers, with both paying somewhere around 9 cents/gal. C3+ is a mix of LPGs.
The relatively low uncommitted rates suggest Sunoco could be trying to capture some market share, according to S&P Global Platts Analytics.
