This Schedule 13D relates to common units representing limited partner interests (“Common Units” or “WPZ Common Units”) of Williams Partners L.P., a Delaware limited partnership (the “Issuer” or “WPZ”). Unless specifically amended hereby, the disclosure set forth in the Original Schedule 13D, as amended by Amendment No. 1, Amendment No. 2, Amendment No. 3 and Amendment No. 4, shall remain unchanged.

Item 2. Identity and Background.

The information previously provided in response to Item 2 is hereby amended and restated by replacing the text thereof in its entirety with the following:

(a)

This Schedule 13D is filed by (i) Williams, a Delaware corporation, and (ii) Williams Gas Pipeline, a Delaware limited liability company (collectively, the “Reporting Persons”).

Williams owns directly 100% of Williams Gas Pipeline; accordingly, the Reporting Persons are hereby filing a joint Schedule 13D.

(b)

The principal business address of each of the Reporting Persons is One Williams Center, Tulsa, Oklahoma 74172-0172.

(c)

The principal business of Williams and its affiliates is to operate as an energy infrastructure company focused on connecting North America’s significant hydrocarbon resource plays to growing markets for natural gas, natural gas liquids, and olefins.

(d)

During the past five years, none of the Reporting Persons has (i) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) nor (ii) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of which was or is subject to a judgment, decree, or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

To the Reporting Persons’ knowledge, none of the Listed Persons has been, during the last five years, (i) convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors), or (ii) a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Under the terms of the Merger Agreement, (i) each outstanding WPZ Common Unit held by a unitholder other than Williams, Williams Gas Pipeline and their respective subsidiaries (collectively, other than ACMP and its subsidiaries and WPZ and its subsidiaries, the “Williams Parties”) was converted into the right to receive newly issued common units of ACMP (“ACMP Common Units”) and (ii) each outstanding WPZ Common Unit held by the Williams Parties was converted into the right to receive ACMP Common Units, in each

case in consideration for each WPZ Common Unit that such holder owned at the effective time of the Merger and at the exchange ratio specified in the Merger Agreement. All of the general partner interest in WPZ outstanding immediately prior to the effective time of the Merger was converted into the right to receive ACMP general partner interests (the “ACMP General Partner Interest”) such that, immediately following consummation of the GP Merger, the ACMP General Partner’s ACMP General Partner Interest represented, in the aggregate, 2% of the outstanding ACMP partnership interest. Prior to the closing of the Merger, each Class D limited partner unit of WPZ, all of which were held by Williams or its affiliates, was converted into WPZ Common Units on a one-for-one basis pursuant to the terms of the WPZ partnership agreement.

Following the closing of the Merger, WPZ merged with and into ACMP, with ACMP surviving, ACMP changed its name to Williams Partners L.P., and the separate existence of WPZ ceased.
