This Amendment No. 1 amends and supplements the Schedule 13D first filed August 14, 2014 (the “Original Schedule 13D” and, as amended, this “Schedule 13D”), and is being filed jointly by the Filing Parties with respect to the Common Units, Class B Convertible Units and Subordinated Units of Southcross Energy Partners, L.P. (“SXE”). Capitalized terms used herein but not defined herein shall have the meanings attributed to them in the Original Schedule 13D.

Item 2. Identity and Background

The last paragraph of Item 2 of the Original Schedule 13D is hereby amended and replaced with the following:

Southcross Energy LLC (“SELLC”) holds approximately 29% of Holdings and approximately 29.6% of Holdings GP. Each of (i) SELLC, Charlesbank Capital Partners, LLC (which the Filing Parties understand is the investment advisor to an investment fund which owns a majority of SELLC) (“CCP”), and the other Southcross Parties (as defined in Item 5) and (ii) the Tailwater Parties, which, following the BBTS Distribution, own approximately 34% of Holdings and approximately 34.4% of Holdings GP, have separately filed Schedule 13Ds with respect to the securities to which this Schedule 13D relates. As a result of the relationship of SELLC, CCP, the Southcross Parties, the Tailwater Parties and the Filing Parties among themselves, each of such parties may have been or continue to be members of a group under Rule 13d-5(b) with respect to the Common Units reported as beneficially owned by the Filing Parties in this Schedule 13D, although the Filing Parties do not affirm that, notwithstanding that such a group may have initially existed as of the closing of such transactions giving rise to the acquisition of beneficial ownership of such Common Units, such group is deemed to continue from and after such closing.

Item 4. Purpose of Transaction.

Item 4 of the Original Schedule 13D is hereby amended and supplemented with the following:

On December 5, 2014, BBTS Borrower LP (“BBTS-B”) distributed (the “BBTS Distribution”) its approximately 69.5% interest in Holdings and its approximately 70.4% interest in Holdings GP (together, the “BBTS Interest”) to BBTS Guarantor LP (“Guarantor LP”), Guarantor LP distributed the BBTS Interest to BlackBrush TexStar LP (“BlackBrush”), and BlackBrush distributed (i) 51.14% of the BBTS Interest to EIG BlackBrush Holdings, LLC (“EIG”), which resulted in EIG becoming a limited partner of Holdings and a member of Holdings GP and directly owning approximately 35.5% of Holdings and approximately 36% of Holdings GP and (ii) 48.86% of the BBTS Interest to TW BBTS Aggregator LP (“Aggregator”), which resulted in Aggregator becoming a limited partner of Holdings and a member of Holdings GP and directly owning approximately 34% of Holdings and approximately 34.4% of Holdings GP.

Item 5. Interest in Securities of the Issuer.

Items 5(a)-(c) of the Original Schedule 13D are hereby amended and restated in their entirety as follows:

As of November 7, 2014, 23,800,943 Common Units, 14,633,000 Class B Convertible Units and 12,213,713 Subordinated Units were outstanding, as reported in SXE’s Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2014.

SHB owns of record 2,116,400 Common Units and all 14,633,000 Class B Convertible Units and 12,213,713 Subordinated Units that are outstanding. SHB is owned 100% by Southcross Holdings Guarantor LP (“Guarantor”) and its non-economic general partner interest is held by Southcross Holdings Borrower GP LLC (“SHB GP”), which is owned 100% by Guarantor. Guarantor is owned 100% by Holdings and its non-economic general partner interest is held by Southcross Holdings Guarantor GP LLC (“Guarantor GP”), which is owned 100% by Holdings (SHB, SHB GP, Guarantor, Guarantor GP, Holdings and Holdings GP are referred to collectively as the “Southcross Parties”).

Page 14 of 17

Immediately prior to the BBTS Distribution, BBTS-B owned approximately 69.5% of Holdings and approximately 70.4% of Holdings GP. On December 4, 2014, BBTS-B distributed the BBTS Interest to Guarantor LP, Guarantor LP distributed the BBTS Interest to BlackBrush, and BlackBrush distributed (i) 51.14% of the BBTS Interest to EIG, which resulted in EIG becoming a limited partner of Holdings and a member of Holdings GP and directly owning approximately 35.5% of Holdings and approximately 36% of Holdings GP and (ii) 48.86% of the BBTS Interest to Aggregator, which resulted in Aggregator becoming a limited partner of Holdings and a member of Holdings GP and directly owning approximately 34% of Holdings and approximately 34.4% of Holdings GP.

In connection with the BBTS Distribution, EIG and Aggregator became parties to that certain Second Amended and Restated Limited Liability Company Agreement of Holdings GP dated November 21, 2014 (the “Holdings GP Agreement”) and that certain Second Amended and Restated Limited Partnership Agreement of Holdings dated November 21, 2014 (the “Holdings LP Agreement”). Pursuant to the Holdings GP Agreement, EIG has the right to designate two directors to the Holdings GP Board and two directors to the SXE Board (one of whom must be an Independent Director). The Partnership Agreement, Holdings GP Agreement and the Holdings LP Agreement govern the voting and disposition of Common Units held by SHB.

As a result of the relationship of EIG to Holdings and Holdings GP and the relationship of the Filing Parties among themselves, each Filing Party may be deemed to have shared power to vote, or direct the disposition of, and to dispose, or direct the disposition of, the Common Units, Class B Convertible Units and Subordinated Units held of record by SHB, which (giving effect to the conversion of such Class B Convertible Units and Subordinated Units) constitutes approximately 57.2% of the Common Units.

Other than as described above, there have been no reportable transactions in the Common Units, Class B Convertible Units or Subordinated Units that were effected in the last 60 days by the Filing Parties.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Item 6 of the Original Schedule 13D is hereby amended and supplemented with the following:

In connection with the BBTS Distribution, EIG and Aggregator became parties to the Holdings GP Agreement and the Holdings LP Agreement. Pursuant to the Holdings GP Agreement, EIG has the right to designate two directors to the Holdings GP Board and two directors to the SXE Board (one of whom must be an Independent Director). The Partnership Agreement, Holdings GP Agreement and the Holdings LP Agreement govern the voting and disposition of Common Units held by SHB.

In connection with the BBTS Distribution, the BBTS Letter Agreement terminated in accordance with its terms.
