SUMMARY ORDER
In 1998, Defendant-Appellant Joel Vasquez was sentenced to 660 months’ imprisonment on his convictions for numerous narcotics, robbery, and firearm offenses. Years after his sentencing, Amendment 782 of the United States Sentencing Guidelines reduced the base offense level for his narcotics convictions. On June 3, 2020, the District Court (Dearie, J.) granted Vasquezs motion to reduce his sentence under 18 U.S.C. § 3582(c)(2) in light of Amendment 782, and reduced the sentence on his narcotics convictions by 68 months, the maximum permitted under § 3582(c)(2) and U.S.S.G. § 1B1.10. Vasquez now appeals from the amended criminal judgment reflecting the reduced sentence. He argues that this Court should grant him relief for alleged errors in his overall sentence that are unrelated to Amendment 782, notwithstanding that he elected not to raise those issues before the District Court—because the District Court lacked the authority to entertain them. We assume the parties’ familiarity with the underlying facts, the procedural history of the case, and the issues on appeal, to which we refer only as necessary to explain our dismissal of the appeal.
On appeal, Vasquez does not challenge the District Courts grant of his motion for a reduction in light of Amendment 782. Rather, he raises two unrelated issues pertaining to his original sentence: (1) the District Courts treatment of the Guidelines as mandatory at his 1998 sentencing before they were rendered advisory in United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005); and (2) the District Courts refusal to consider, under Dean v. United States, ––– U.S. ––––, 137 S. Ct. 1170, 197 L.Ed.2d 490 (2017), the severe effect of the consecutive mandatory minimum sentences of the firearm convictions under 18 U.S.C. § 924(c).
We must dismiss this appeal because it is not a proper vehicle for raising these two issues. Before the District Court was only a motion to reduce a sentence under § 3582(c)(2). Section 3582(c)(2) “narrow[ly]” authorizes courts to reduce the portion of a sentence impacted by a Guidelines amendment. Dillon v. United States, 560 U.S. 817, 825-26, 130 S.Ct. 2683, 177 L.Ed.2d 271 (2010). “[N]either the district court nor this Court is free to address, in a proceeding pursuant to 18 U.S.C. § 3582(c)(2), [a] defendants arguments regarding procedural errors at his original, now-final sentencing” if those purported errors are unrelated to any Guidelines amendment. United States v. Mock, 612 F.3d 133, 135 (2d Cir. 2010); see also id. at 138 (“[R]egardless of whether there is merit to defendants argument that the district court committed procedural error ․ at his original sentencing, neither the district court nor this Court is authorized to consider that contention in the context of a motion pursuant to 18 U.S.C. § 3582(c)(2).”). “Because the aspects of his sentence that [Vasquez] seeks to correct were not affected by the [Guidelines] amendment ․ they are outside the scope of the proceeding authorized by § 3582(c)(2)․” Dillon, 560 U.S. at 831, 130 S.Ct. 2683. Johnson v. United States, 623 F.3d 41 (2d Cir. 2010), the sole case cited by Vasquez in support of his contrary position, is not persuasive. In Johnson, we addressed only the question of when a 28 U.S.C. § 2255 petition qualifies as second or successive, not the issue here of what sentencing errors may be raised in an appeal from an amended criminal judgment following a § 3582(c)(2) motion.
For the foregoing reasons, we DISMISS the appeal.
