MEMORANDUM **

Jose Luis Bernal-Arias appeals from the district court’s judgment and challenges the 60-month sentence imposed following his guilty-plea conviction for conspiracy to possess with intent to distribute heroin, in violation of 21 U.S.C. §§ 841(a)(1), 841(b)(l)(B)(i), and 846. We dismiss.

Bernal-Arias challenges the district court’s finding that he was not safety valve eligible, as well as the district court’s decision to apply a two-level enhancement for maintaining a premises for the purpose of manufacturing or distributing a controlled substance. The government contends that the appeal is barred by an appeal waiver in the parties’ plea agreement. We review de novo whether the appeal is barred by a waiver. See United States v. Arias-Espinosa, 704 F.3d 616, 618 (9th Cir. 2012).

The appeal waiver in the parties’ plea agreement covers Bernal-Arias’s claims, and the record reflects that the waiver was knowing and voluntary. See United States v. Harris, 628 F.3d 1203, 1205 (9th Cir. 2011). Nonetheless, Bernal-Arias argues that the district court vitiated the written waiver at sentencing. This claim fails because the court’s statement regarding Ber-nal-Arias’s right to appeal was qualified. See Arias-Espinosa, 704 F.3d at 618-20. We also reject Bernal-Arias’s call to ignore the appeal waiver to prevent a “miscarriage of justice.” Even assuming this court recognized such an exception to the enforceability of an appeal waiver, it does not apply here.

DISMISSED.
