Subsequent Events [Abstract]
Subsequent Events	Subsequent Events Recognizable events No recognizable events have occurred subsequent to December 31, 2019. Non-recognizable events On January 21, 2020, we announced an agreement to sell three marine terminals to Buckeye Partners, L.P. for $250 million. The terminals are located in New Haven, Connecticut, Wilmington, Delaware and Marrero, Louisiana. The sales price approximates the net book value of our investment in these terminals, and the impact of this transaction is not expected to be material to our 2020 financial statements. Also on January 21, 2020, we announced that our general partner’s board of directors authorized the repurchase of up to $750 million of common units through 2022. We intend to purchase our common units from time-to-time through a variety of methods, including open market purchases and negotiated transactions, all in compliance with the rules of the Securities and Exchange Commission and other applicable legal requirements. On February 14, 2020, we paid cash distributions of $1.0275 per unit on our outstanding common units to unitholders of record at the close of business on February 7, 2020.
