        This Amendment No. 3 on Schedule 13D/A (“Amendment No. 3”) is being filed by Dan L. Duncan, an individual residing in Houston, Texas (“Dan Duncan”), Enterprise Products Delaware Holdings, L.P., a Delaware limited partnership (“EPDH”), EPC Partners II, Inc., a Delaware corporation (“EPC Partners”) and Enterprise Products Company, a Texas corporation (“EPCO”) to amend the Schedule 13D originally filed on August 14, 2003, as amended by Amendment No. 1 thereto, filed September 12, 2003 and Amendment No. 2 thereto, filed December 19, 2003 (the “Original Schedule 13D”), by Dan Duncan, EPDH, EPC Partners and EPCO (collectively, the “Reporting Persons”).

        Unless otherwise defined herein, capitalized terms used herein shall have the meanings set forth in the Original Schedule 13D.

Item 1.  Security and Issuer.

        No change to this Item.

Item 2.  Identity and Background.

        No change to this Item.

Item 3.  Source and Amount of Funds or Other Consideration.

        Item 3 of the Original Schedule 13D is hereby amended by adding the following at the end of such item:

        On February 11, 2004, EPDH purchased 930,669 Common Units pursuant to the Issuer’s Distribution Reinvestment Plan. The source of the funds used to purchase such Common Units pursuant to the Distribution Reinvestment Plan was the quarterly cash distributions on the Common Units currently held by EPDH.

        On May 3, 2004 and May 4, 2004, Dan Duncan purchased an aggregate of 200,000 Common Units. The source of the funds used to purchase such Common Units was cash advances from EPCO.

         On May 3, 2004 and May 4, 2004, the Duncan Family 1998 Trust purchased an aggregate of 200,000 Common Units. The source of funds was the Duncan Family 1998 Trust’s cash on hand. Dan Duncan has the sole power to direct the voting and disposition of the Common Units held in the Duncan Family 1998 Trust and therefore beneficially owns all of the Common Units held in the Duncan Family 1998 Trust.

        On May 3, 2004, May 6, 2004, May 7, 2004 and May 10, 2004, EPCO purchased an aggregate of 531,200 Common Units. The source of the funds was EPCO’s cash on hand.

        On May 12, 2004, EPDH purchased 1,527,694 Common Units pursuant to the Issuer’s Distribution Reinvestment Plan. The source of the funds used to purchase such Common Units pursuant to the Distribution Reinvestment Plan was the quarterly cash distributions on the Common Units currently held by EPDH.

        On May 12, 2004, the Duncan Family 2000 Trust, purchased 81,488 Common Units pursuant to the Issuer’s Distribution Reinvestment Plan. Dan Duncan has the sole power to direct the voting and disposition of the Common Units held in the Duncan Family 2000 Trust and therefore beneficially owns all of the Common Units held in the Duncan Family 2000 Trust.

The source of the funds used to purchase such Common Units pursuant to the Distribution Reinvestment Plan was the quarterly cash distributions on the Common Units currently held by EPDH.

Item 4.  Purpose of the Transaction.

        No change to this Item.

Item 5.  Interest in Securities of the Issuer.

        Item 5 of the Original Schedule 13D is deleted in its entirety and the following is substituted in lieu thereof:

        (a)   EPDH holds directly 110,458,481 Common Units. EPDH is an indirect wholly-owned subsidiary of EPC Partners. Accordingly, EPC Partners has an indirect beneficial ownership interest in the 110,458,481 Common Units owned by EPDH.

        EPC Partners is a wholly-owned subsidiary of EPCO. Therefore, EPCO has an indirect beneficial ownership interest in the 110,458,481 Common Units held by EPDH.

        EPCO holds directly 531,200 Common Units. Dan Duncan owns 50.473% of the voting stock of EPCO, therefore, Dan Duncan has an indirect beneficial ownership interest in the 531,200 Common Units held by EPCO.

        Dan Duncan is the record owner of 311,600 Common Units. Therefore, Dan Duncan exercises sole voting and dispositive power with respect to the 311,600 Common Units that he owns. In addition, Dan Duncan has the sole power to direct the voting and disposition of the Common Units held by (1) the Duncan Family 1998 Trust, which owns 4,478,200 Common Units, and (2) the Duncan Family 2000 Trust, which owns 4,381,524 Common Units. Therefore, Dan Duncan is also the beneficial owner of the 4,478,200 and 4,381,524 Common Units held by the Duncan Family 1998 Trust and the Duncan Family 2000 Trust, respectively.

        Dan Duncan owns 50.437% of the voting stock of EPCO and, accordingly, exercises shared voting and dispositive power with respect to the 110,989,681 Common Units beneficially owned by EPCO, which, together with Dan Duncan’s 311,600 Common Units, the 4,478,200 Common Units owned by the Duncan Family 1998 Trust, and the 4,381,524 Common Units owned by the Duncan Family 2000 Trust, represents 51.4% of the outstanding Common Units (based upon the number of Common Units outstanding as of May 26, 2004). The remaining shares of EPCO capital stock are owned primarily by trusts established for the benefit of Dan Duncan’s family.

        (b)   As set forth herein, Dan Duncan has sole voting and dispositive power over the 311,600 Common Units that he owns, the 4,478,200 Common Units owned by the Duncan Family 1998 Trust, and the 4,381,524 Common Units owned by the Duncan Family 2000 Trust. Dan Duncan also has shared voting and dispositive power over the 110,989,681 Common Units beneficially owned by EPCO.
