SUMMARY ORDER

Defendant-appellant Jaime Alberto Mejia Gonzalez (“Mejia”) appeals the District Court’s denial of his motion for a sentence reduction pursuant to 18 U.S.C. § 3582(c)(2) and Amendment 782 to the U.S. Sentencing Guidelines, which lowered the base offense levels applicable to most drug crimes under U.S.S.G. § 2D1.1. We assume the parties’ familiarity with the underlying facts, the procedural history of the case, and the issues on appeal.

Section 3582(c)(2) provides that a sentencing court may reduce a defendant’s term of imprisonment if his sentence was based on a sentencing range subsequently lowered by the Sentencing Commission. Under Dillon v. United States, 560 U.S. 817, 826, 130 S.Ct. 2683, 177 L.Ed.2d 271 (2010), district courts must follow a “two-step inquiry” when deciding motions for a sentence reduction. The court must first determine whether the prisoner is eligible for a reduction. Then, if the prisoner is eligible, the court must determine, in its discretion, whether a reduction is warranted. We review de novo a district court’s ruling regarding a defendant’s eligibility for § 3582(c)(2) relief. See United States v. Christie, 736 F.3d 191, 195 (2d Cir. 2013).

We agree with the District Court that Mejia is ineligible for a reduction pursuant to § 3582(c)(2) as a matter of law. A district court may not reduce a sentence pursuant to § 3582(c)(2) if “the amendment does not have the effect of lowering the defendant’s applicable guideline range,” as is the case here. Mejia pleaded guilty to one count of conspiracy to distribute and possess with the intent to distribute more than 150 kilograms of cocaine, in violation of 21 U.S.C. §§ 841(a)(1)(C), 841(b)(l)(A)(ii)(II) and 846. At his sentencing, the District Court found Mejia to be responsible for 10,000 kilograms of cocaine. Amendment 782 to the U.S. Sentencing Guidelines raised the quantity of cocaine involved in a level 38 offense from 150 kilograms or more to 450 kilograms of cocaine or more. Because the District Court found Mejia to have been responsible for 10,000 kilograms of cocaine, Amendment 782 did not lower his applicable guideline. The District Court thus lacked the authority to reduce Mejia’s sentence and properly rejected this challenge.

Mejia also argues that the District Court should not have relied on the Presentence Investigation Report’s (“PSR”) determination regarding the quantity of drugs during his sentencing. We find this argument to be meritless. The Supreme Court has clearly articulated that the scope of § 3582 review is limited and instructed district courts to “leave all other guideline application decisions unaffected.” Dillon, 560 U.S. at 831, 130 S.Ct. 2683. The District Court “cannot make findings inconsistent with that of the original sentencing court.” United States v. Rios, 765 F.3d 133, 138 (2d Cir. 2014) (internal quotation marks omitted). Even if there were statutory authority under § 3582, Mejia forfeited this claim by failing to raise it on direct appeal. Therefore, we need not consider this argument further.

*52 CONCLUSION

We have reviewed the remaining arguments raised by the defendant on appeal and find them to be without merit. For the foregoing reasons, we AFFIRM the order of the District Court.
