DEREGISTRATION OF UNSOLD SECURITIES

This Post-Effective Amendment No. 1 to the Registration Statement on Form S-3 (File No. 333-186887) (the “Registration Statement”) initially filed with the Securities and Exchange Commission on February 27, 2013 by El Paso Pipeline Partners, L.P., a Delaware limited partnership (“EPB”), is being filed to deregister all unsold securities of EPB (the “Registered Securities”) that were registered under the Registration Statement.

Effective on November 26, 2014, Kinder Morgan, Inc. (“KMI”) completed the acquisition of EPB, pursuant to the Agreement and Plan of Merger dated August 9, 2014 (the “Merger Agreement”), by and among KMI, EPB, E Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of KMI (“E Merger Sub”) and the other parties thereto.

Pursuant to the Merger Agreement, E Merger Sub was merged with and into EPB, with EPB surviving the merger as a wholly owned subsidiary of KMI (the “Merger”). As a result of the Merger, each outstanding common unit of EPB not owned by KMI and its subsidiaries was automatically converted into the right to receive the merger consideration described in the Merger Agreement.

As a result of the Merger, EPB has terminated all offerings of its securities pursuant to its existing registration statements, including the Registration Statement. In accordance with an undertaking made by EPB in the Registration Statement to remove by means of a post-effective amendment any securities that were registered under the Registration Statement which remain unsold at the termination of the offering, EPB hereby de-registers $137,964,953.36 of the Registered Securities, all of which remained unsold at the effective time of the Merger.
