Artis Sherman, federal prisoner # 36280-177, seeks leave to proceed in for-ma pauperis (IFP) on appeal from the district court’s denial of his 18 U.S.C. § 3582(c)(2) motion to reduce his sentence based on recent amendments to the Sentencing Guidelines for crack cocaine. He pleaded guilty to conspiracy to possess with the intent to distribute 50 grams or more of crack cocaine and was sentenced as a career offender under U.S.S.G. § 4B1.1 to 300 months of imprisonment. By moving to proceed IFP, Sherman is challenging the district court’s certification decision that his appeal was not taken in good faith because it is frivolous. See Baugh v. Taylor, 117 F.3d 197, 202 (5th Cir. 1997).

On appeal, Sherman argues that he is entitled to resentencing under Amendment 706 to the Guidelines because as a career offender, his offense level was based on the quantity of crack cocaine for which he was held responsible. His guidelines imprisonment range was not derived from the quantity of crack cocaine involved in the offense but rather from his status as a career offender. Therefore, the district court was correct in concluding that a sentencing reduction was not permitted. See § 3582(c)(2); United States v. Anderson, 591 F.3d 789, 790-91 (5th Cir. 2009).

He also challenges his status as a career offender. A § 3582(c)(2) motion may not be used to challenge a district court’s calculation of an original sentence or to contest the appropriateness of the sentence. United States v. Whitebird, 55 F.3d 1007, 1011 (5th Cir. 1995). Thus, Sherman’s challenges to his status as a career offender are not cognizable in a § 3582(c)(2) motion. See id.

Sherman further argues that he is entitled to a full resentencing under the holding of United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), and contends that his sentence is unreasonable. The Supreme Court’s decision in Booker does not apply to sentence reductions under § 3582(c)(2) because such proceedings are not full resentencings. United States v. Doublin, 572 F.3d 235, 238 (5th Cir.), cert. denied, — U.S. -, 130 S.Ct. 517, 175 L.Ed.2d 366 (2009); see also Dillon v. United States, — U.S. -, ---, 130 S.Ct. 2683, 2691-94, 177 L.Ed.2d 271 (2010) (holding that Booker does not apply to § 3582(c)(2) proceedings). Additionally, the Booker reasonableness standard does not apply in § 3582(c)(2) proceedings. United States v. Evans, 587 F.3d 667, 672 (5th Cir. 2009), cert. denied, — U.S. -, 130 S.Ct. 3462, 177 L.Ed.2d 1064 (2010).

Sherman has failed to show that he will raise a nonfrivolous issue on appeal. See Howard v. King, 707 F.2d 215, 220 (5th Cir. 1983). Accordingly, his IFP motion is DENIED. Because the appeal is frivolous, it is DISMISSED. See 5th Cir. R. 42.2.
