Risks and Uncertainties [Abstract]
Concentration Risk Disclosure [Text Block]	17. Concentration Risk We are part of the consolidated operations of Western, and we derive a substantial portion of our revenue from transactions with Western and its affiliates. Western accounted for approximately 28.9%, 25.9% and 24.5%, respectively, of our consolidated revenues for the years ended December 31, 2014, 2013 and 2012. These percentages are not comparable as Western did not charge for the Predecessor's services in prior years. Prior to the completion of the Offering, our Predecessor did not record all revenues for intercompany gathering, pipeline transportation, terminalling and storage services. We sell a variety of refined products to a diverse customer base. Sales to Kroger Company accounted for 23.0%, 27.1%, and 26.2% of consolidated net sales for the years ended December 31, 2014, 2013 and 2012, respectively. Sales to Western’s retail group accounted for 23.6%, 24.2% and 23.8% of consolidated net sales for the years ended December 31, 2014, 2013 and 2012, respectively. Sales of finished product to Western’s retail segment were historically at no margin. See Note 21, Related Party Transactions, for detailed information on our agreements with Western.
