OPINION OF THE COURT

Juan Sanchez appeals the District Court’s denial of his motion for a modification of his sentence in light of the retroactive amendments to the crack cocaine Sentencing Guidelines. His attorney has moved to withdraw his representation under Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967). We will grant the motion to withdraw and will affirm the District Court’s order.

This Court’s rules provide that “[w]here, upon review of the district court record, trial counsel is persuaded that the appeal presents no issue of even arguable merit, counsel may file a motion to withdraw and supporting brief pursuant to Anders.” 3d Cir. LAR 109.2(a). If we concur with trial counsel’s assessment, we “will grant [the] Anders motion, and dispose of the appeal without appointing new counsel.” Id. Accordingly, our “inquiry when counsel submits an Anders brief is thus twofold ... :(1) whether counsel adequately fulfilled the rule’s requirements; and (2) whether an independent review of the record presents any nonfrivolous issues.” United States v. Youla, 241 F.3d 296, 300 (3d Cir. 2001).

Our review of the record has convinced us that trial counsel’s Anders brief is adequate and that there are no nonfrivolous grounds on which to challenge the District Court’s denial of Sanchez’s motion for a sentence reduction.

The District Court correctly held that Sanchez was ineligible for a sentence reduction under the retroactive amendments to the crack cocaine Sentencing Guidelines. While the amendments to U.S.S.G. § 2D1.1 lower the base offense *309level for most offenses involving crack cocaine, they do not apply here. Application Note 10 to U.S.S.G. § 2D1.1 provides in pertinent part that the two-level reduction “shall not apply” when “the [two]-level reduction results in a combined offense level that is less than the combined offense level that would apply ... if the offense involved only the other controlled substance(s) (ie., the controlled substances other than cocaine base).” U.S.S.G. § 2D1.1 cmt. n. 10(D)(ii)(II). Here, the District Court found that, if Sanchez’s Guidelines sentence were recalculated disregarding the crack cocaine, the marijuana equivalent drug weight would total 793.219 kilograms. That weight yields the same base offense level of 30 that was utilized at Sanchez’s original sentencing. Thus, a two-level reduction for Sanchez would result in a base offense level less than the offense level that would apply in the absence of any crack cocaine. We find no error.

Sanchez, in his supplemental pro se briefing before the District Court and this Court, seeks review of alleged errors occurring in his original sentencing and proceedings on his subsequent motion under 28 U.S.C. § 2255.1 However, as the District Court recognized, 18 U.S.C. § 3582(c)(2) only authorized it to apply Amendment 706. It did not allow the District Court to visit other sentencing issues. United States v. Mateo, 560 F.3d 152, 155-56 (3d Cir. 2009).2

Because our independent review of the record fails to reveal any nonfrivolous grounds for appeal, we will grant counsel’s motion to withdraw and will affirm the judgment of the District Court. In addition, we certify that the issues presented in this appeal lack legal merit and thus that counsel is not required to file a petition for writ of certiorari with the Supreme Court. 3d Cir. LAR 109.2(b).
