Re: ADS Waste Holdings, Inc.

Ladies and Gentlemen:

We have acted as special Maryland counsel to Western Maryland Waste Systems, LLC, a Maryland limited liability company (“Guarantor”), in connection with the filing by ADS Waste Holdings, Inc., a Delaware corporation (the “Company”) and parent of Guarantor, of a Registration Statement on Form S-4 filed on September 11, 2013 (the “Registration Statement”) with the United States Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the issuance of the Company’s 8  ¹⁄₄% Senior Notes due 2020 (the “Exchange Notes”) and the full and unconditional guarantee, on a senior unsecured basis, as to the payment of principal and interest on the Exchange Notes by Guarantor and other subsidiaries of the Company pursuant to the terms of an indenture, dated as of October 9, 2012 (as amended and supplemented, the “Indenture”), among ADS Waste Escrow Corp. and Wells Fargo Bank, National Association, as trustee (the “Trustee”) and the supplemental indenture, dated as of November 20, 2012, among the Company, Guarantor, certain other subsidiaries of the Company and the Trustee (the “Supplemental Indenture”). Pursuant to the prospectus forming a part of the Registration Statement (the “Prospectus”), the Company is offering to exchange (the “Exchange Offer”) up to $550,000,000 aggregate principal amount of Exchange Notes for a like amount of its outstanding 8  ¹⁄₄% Senior Notes due 2020 issued on October 9, 2012 (the “Old Notes”), which have not been registered under the Securities Act. The Exchange Notes, as guaranteed by Guarantor and certain other subsidiaries of the Company pursuant to the terms of the Indenture and Supplemental Indenture, will be registered under the Securities Act as set forth in the Registration Statement and will be issued upon consummation of the Exchange Offer. Pursuant to the requirements of Section 5(q) of the Indenture, we have been requested by the Company to render the legal opinions hereinafter expressed

(d) that all persons executing Documents on behalf of any party (other than Guarantor) are duly authorized;

We have not examined any court records, dockets, or other public records, nor have we investigated the history or other transactions of Guarantor, except as specifically set forth in this letter.
