Ladies and Gentlemen:

We are acting as counsel to Suburban Propane Partners, L.P., a Delaware limited partnership (the “Partnership”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”), under the Securities Act of 1933, as amended (the “Securities Act”), of a registration statement on Form S-3 (the “Registration Statement”), including a prospectus (the “Prospectus”), relating to the registration of common units representing limited partner interests in the Partnership (the “Common Units”) having an aggregate offering amount of up to $100,000,000. The Common Units will be issued and sold from time to time pursuant to the Registration Statement and an Equity Distribution Agreement, to be entered into by and among the Partnership and Wells Fargo Securities, LLC, J.P. Morgan Securities LLC, BofA Securities, Inc., and Evercore Group L.L.C., each acting as a sales agent and/or principal (the “Equity Distribution Agreement”) in one or more transactions deemed to be “at the market” offerings under Rule 415 of the Securities Act.

As such counsel, we have participated in the preparation of the Registration Statement and have examined originals or copies of such documents, limited partnership records and other instruments as we have deemed relevant, including, without limitation: (i) the Partnership’s Certificate of Limited Partnership, as amended to date (the “Certificate of Limited Partnership”); (ii) the Partnership’s Third Amended and Restated Agreement of Limited Partnership, dated as of October 19, 2006, as amended (the “Partnership Agreement”); (iii) a certificate, dated on or about the date hereof, issued by the Secretary of State of the State of Delaware, as to the Partnership’s existence and good standing in such jurisdiction; (iv) certain of the resolutions of the Board of Supervisors of the Partnership relating to the Equity Distribution Agreement and the authorization for the issuance of the Common Units; (v) the form of the Equity Distribution Agreement; (vi) the Registration Statement, together with the exhibits filed as a part thereof and including any documents incorporated by reference therein, and the Prospectus included therein; and (vii) such other documents and matters as we have determined to be necessary or appropriate to express the opinion set forth below, subject to the assumptions, limitations and qualifications stated herein.

As to matters of fact relevant to this opinion, we have relied upon, and assumed without independent verification, the accuracy of certificates of public officials and officers of the Partnership. We have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of documents submitted to us as originals, the conformity to the original documents of all documents submitted to us as certified, facsimile or photostatic copies, and the authenticity of the originals of such copies.
