Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	INCOME TAXES The Partnership’s effective tax rate differs from the statutory rate primarily due to Partnership earnings that are not subject to United States federal and most state income taxes at the Partnership level. For the three months ended March 31, 2018 the Partnership’s income tax benefit also reflected a $38 million deferred benefit adjustment as the result of a state statutory rate reduction.
