Pursuant to a plea agreement, Jaime Ramon Garcia Lozano-Alcorta pleaded guilty to one count of possession with intent to distribute five' kilograms or more of cocaine. As part of the plea agreement, Lozano-Alcorta agreed to waive his “right to appeal the conviction, the sentence imposed or the manner in which the sentence was determined.” The district court sentenced him to 80 months of imprisonment and five years of supervised release.

Lozano-Alcorta has filed a timely notice of appeal and contends that the district court erred regarding his sentence by refusing to grant a downward departure based on prospective amendments to the drug quantity tables in U.S.S.G. § 2D1.1. According to Lozano-Alcorta, the appeal waiver in his plea agreement is invalid because he could not have knowingly waived the right to appeal a sentence that had not yet been imposed. The Government seeks dismissal of the appeal based on the appeal waiver.

The validity of an appeal waiver is reviewed de novo. United States v. Rodriguez-Estrada, 741 F.3d 648, 650 (5th Cir. 2014). For a defendant’s waiver of his right to appeal to be knowing and voluntary, the “defendant must know that he had a right to appeal his sentence and that he was giving up that right.” United States v. Portillo, 18 F.3d 290, 292 (5th Cir. 1994) (internal quotation marks and citation omitted). Lozano-Alcorta’s challenge to his appeal waiver is unavailing. See United States v. Melancon, 972 F.2d 566, 567-68 (5th Cir. 1992). The waiver is enforceable and encompasses Lozano-Al-corta’s challenge to his sentence.

Accordingly, the appeal is DISMISSED.
