MEMORANDUM **

In these consolidated appeals, Darrell L Snyder appeals from the district court’s order denying his motion for a sentence reduction under 18 U.S.C., § 3582(c)(2). We have jurisdiction under 28 U.S.C. § 1291, and we affirm.

Snyder contends that he is entitled to a sentence reduction under Amendment 782. Reviewing de novo, see United States v. Leniear, 574 F.3d 668, 672 (9th Cir. 2009), we agree with the district court that it lacked authority to reduce Snyder’s sentence. The sentencing court determined that Snyder was responsible for 1,068 kilograms of cocaine. Thus, his base offense level remains a 38 under Amendment 782, see U.S.S.G. § 201.1(c)(1) (2014), and he is ineligible for a sentence reduction. See Leniear, 574 F.3d at 674.

Snyder nonetheless contends that the district court erred in determining that he was responsible for 1,068 kilograms of cocaine, the amount calculated in the presen-tence report, and should have relied instead on the lower quantity of drugs for which he admitted responsibility in his plea agreement. We disagree. The record shows that the sentencing court adopted the drug quantity calculated in the undisputed presentence report, and Snyder cannot challenge that calculation in these proceedings. See Dillon v. United States, 560 U.S. 817, 826, 831, 130 S.Ct. 2683, 177 L.Ed.2d 271 (2010) (section 3582(c)(2) does not authorize a plenary resentencing hearing).

AFFIRMED.
