Partners LLC, the general partner of Sunoco Logistics Partners L.P. (&#8220;Sunoco Logistics&#8221;), approved the appointment of Grant Thornton LLP (&#8220;Grant Thornton&#8221;) to serve as Sunoco Logistics&#8217; new independent registered public accounting firm for the fiscal year ending December&#160;31, 2013 and approved the dismissal of Ernst &amp; Young LLP (&#8220;Ernst &amp; Young&#8221;) as its independent registered public accounting firm.  Sunoco Logistics notified Ernst &amp; Young of its dismissal on April 1, 2013.  The decision was made as part of the integration process related to the recently completed acquisition of Sunoco Logistics&#8217; general partner by Energy Transfer Partners, L.P. (&#8220;ETP&#8221;).  The acquisition resulted in Sunoco Logistics becoming a consolidated subsidiary of ETP.

  Item 4.01.
  Changes in Registrant's Certifying Accountant.
  On April 1, 2013, the Board of Directors of Sunoco Partners LLC, the general partner of Sunoco Logistics Partners L.P. ("Sunoco Logistics"), approved the appointment of Grant Thornton LLP ("Grant Thornton") to serve as Sunoco Logistics' new independent registered public accounting firm for the fiscal year ending December 31, 2013 and approved the dismissal of Ernst & Young LLP ("Ernst & Young") as its independent registered public accounting firm.  Sunoco Logistics notified Ernst & Young of its dismissal on April 1, 2013.  The decision was made as part of the integration process related to the recently completed acquisition of Sunoco Logistics' general partner by Energy Transfer Partners, L.P. ("ETP").  The acquisition resulted in Sunoco Logistics becoming a consolidated subsidiary of ETP.  As Grant Thornton currently serves as ETP's independent registered public accounting firm, Sunoco Logistics' board determined that it would be beneficial for ETP and Sunoco Logistics to have the same firm audit their respective financial statements.
  The audit reports of Ernst & Young on the consolidated financial statements of Sunoco Logistics as of December 31, 2012 and for the period from October 5, 2012 to December 31, 2012 and the effectiveness of Sunoco Logistics' internal control over financial reporting as of December 31, 2012 were expressly relied upon by Grant Thornton, ETP's independent registered public accounting firm, in Grant Thornton's audit reports on the consolidated financial statements of ETP as of and for the year ended December 31, 2012 and the effectiveness of ETP's internal control over financial reporting as of December 31, 2012.  Grant Thornton will continue to act as the independent registered public accounting firm of ETP.
  The audit reports of Ernst & Young on the consolidated financial statements of Sunoco Logistics as of December 31, 2012 and 2011, and for the periods from October 5, 2012 to December 31, 2012, from January 1, 2012 to October 4, 2012, and the years ended December 31, 2011 and 2010, did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.  The audit reports of Ernst & Young on the effectiveness of Sunoco Logistics' internal control over financial reporting as of December 31, 2012 and December 31, 2011 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.
  During Sunoco Logistics' fiscal years ended December 31, 2012 and December 31, 2011, and during the subsequent interim period through April 1, 2013, the date of the dismissal of Ernst & Young, there were no (1) disagreements with Ernst & Young on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures, which disagreements, if not resolved to the satisfaction of Ernst & Young, would have caused Ernst & Young to make reference in connection with their report to the subject matter of the disagreement, or (2) "reportable events" as defined in Item 304(a)(1)(v) of Regulation S-K.
  ETP provided Ernst & Young with a copy of this Current Report on Form 8-K, and requested that Ernst & Young furnish ETP with a letter addressed to the Securities and Exchange Commission stating whether Ernst & Young agrees with the statements made by ETP in response to the disclosures required by Item 304(a) of Regulation S-K.  ETP subsequently received the requested letter, and a copy of such letter is filed as Exhibit 16.1 to this Current Report on Form 8-K.
  During Sunoco Logistics' fiscal years ended December 31, 2012 and December 31, 2011, and during the subsequent interim period through April 1, 2013, neither Sunoco Logistics nor anyone acting on Sunoco Logistics' behalf consulted with Grant Thornton regarding any of the matters specified in Item 304(a)(2) of Regulation S-K.
