Ladies and Gentlemen:

We have acted as counsel to Enterprise Products Partners L.P., a Delaware limited partnership (the “Partnership”), in connection with the preparation of a Post-Effective Amendment No. 1 (the “Post-Effective Amendment”) to the Registration Statement on Form S-3D filed by the Partnership with the Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of 1933, as amended (the “Securities Act”) on May 12, 2016 (File No. 333-211318) (as amended by the Post-Effective Amendment, the “Registration Statement”). The Registration Statement relates to the offering of up to 104,963,257 common units representing limited partner interests (the “Common Units”), which may be issued pursuant to the Partnership’s Distribution Reinvestment Plan. In connection therewith, we have participated in the preparation of the discussion set forth under the caption “Material U.S. Federal Income Tax Consequences” in the Registration Statement (the “Discussion”). All capitalized terms used but not defined herein have the respective meanings assigned to such terms in the Registration Statement.

This opinion is based on various facts and assumptions, and is conditioned upon certain representations made to us by the Partnership as to factual matters through an officer’s certificate (the “Officer’s Certificate”). In addition, this opinion is based upon the factual representations of the Partnership concerning its business, properties and governing documents as set forth in the Registration Statement and the Partnership’s responses to our examinations and inquiries.

In our capacity as counsel to the Partnership, we have made such legal and factual examinations and inquiries, including an examination of originals or copies certified or otherwise identified to our satisfaction of such documents, corporate records and other instruments, as we have deemed necessary or appropriate for purposes of this opinion. In our examination, we have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures thereon, the legal capacity of natural persons executing such documents and the conformity to authentic original documents of all documents submitted to us as copies. For the purpose of our opinion, we have not made an independent investigation or audit of the facts set forth in the above-referenced documents or representations. In addition, in rendering this opinion we have assumed the truth and accuracy of all representations and statements made to us which are qualified as to knowledge or belief, without regard to such qualification.

We hereby confirm that all statements of legal conclusions contained in the Discussion, subject to the qualifications and assumptions stated in the Discussion and the limitations and qualifications set forth herein, constitute the opinion of Sidley Austin LLP with respect to the matters described therein. This opinion is expressed as of the date hereof, and we disclaim any undertaking to advise you of any subsequent changes of the facts stated or assumed therein or any subsequent changes in law.

This opinion is based on various statutory provisions, regulations promulgated thereunder and interpretations thereof by the Internal Revenue Service and the courts having jurisdiction over such matters, all of which are subject to change either prospectively or retroactively. Also, any variation or difference in the facts from those set forth in the representations described above, including in the Registration Statement and the Officer’s Certificate, may affect the conclusions stated herein.

Sidley Austin LLP is a limited liability partnership practicing in affiliation with other Sidley Austin partnerships.

This opinion is furnished to you, and is for your use in connection with the transactions set forth in the Registration Statement. This opinion may not be relied upon by you for any other purpose or furnished to, assigned to, quoted to or relied upon by any other person, firm or other entity, for any purpose, without our prior written consent, except that this opinion may be relied upon by persons entitled to rely on it pursuant to applicable provisions of federal securities law, including purchasers of Common Units in this offering.

Furthermore, our opinion is not binding on the Internal Revenue Service or a court. In addition, we must note that our opinion represents merely our best legal judgment on the matters presented and that others may disagree with our conclusion. There can be no assurance that the Internal Revenue Service will not take a contrary position or that a court would agree with our opinion if litigated.

We hereby consent to the filing of this opinion as an exhibit to the Registration Statement and to the incorporation by reference of this opinion to the Registration Statement. In giving this consent we do not admit that we are included in the category of persons whose consent is required under Section 7 of the Securities Act, or the rules and regulations of the Commission.

Very truly yours,

/s/ Sidley Austin LLP
