    No. 08-31055
    Summary Calendar.
    United States Court of Appeals, Fifth Circuit.
    Nov. 22, 2010.
    Cristina Walker, Assistant U.S. Attorney, U.S. Attorney’s Office, Western District of Louisiana, Shreveport, LA, Richard Allan Willis, U.S. Attorney U.S. Attorney’s Office, Western District of Louisiana, Lafayette, LA, for PlaintiffAppellee.
    Christopher Michael Brown, Coleman, FL, for Defendant-Appellant.
    
      Before JOLLY, GARZA, and STEWART, Circuit Judges.
   PER CURIAM:

Christopher Michael Brown, federal prisoner # 10980-035, was convicted by a jury of one count of conspiracy to distribute cocaine and cocaine base (crack) and four distribution counts. Brown was sentenced to life in prison on the conspiracy count and concurrent terms of 40 year on the distribution counts. Brown now appeals the district court’s denial of his 18 U.S.C. § 3582(c)(2) motion to reduce his sentence based on amendments to the Sentencing Guidelines reducing base offense levels for some crack cocaine offenses. Brown argues that the district court erred by concluding that the amendments did not reduce his sentencing range, asserting that the amendments generally had the effect of reducing base offense levels by two levels; that the application of the 4.5 kilogram threshold for a base offense level of 38 was improperly applied to him retroactively in violation of the Ex Post Facto Clause; that the district court had authority to revisit his sentence and should have treated the Guidelines as advisory rather than mandatory pursuant to United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005); and that the district court should have held an evidentiary hearing. Brown’s arguments are without merit.

Amendment 706 altered the thresholds for crack cocaine offense levels. Previously, more than 1.5 kilograms of crack cocaine resulted in a base offense level of 38; under the amendments, it takes 4.5 kilograms of crack to achieve that offense level. However, Brown was held accountable for 106.667 kilograms of crack cocaine, which is well above the amended amount need for level 38. Thus, the amendments did not affect Brown’s guidelines range, and the district court had no authority to reduce his sentence. See U.S.S.G. § 1B1.10(a)(2)(B), p.s.; United States v. Carter, 595 F.3d 575, 580 (5th Cir.2010).

Brown’s arguments regarding Booker are foreclosed by Dillon v. United States, — U.S. —, 130 S.Ct. 2683, 2691-94, 177 L.Ed.2d 271 (2010), and United States v. Doublin, 572 F.3d 235, 238 (5th Cir.2009). In addition, there was no ex post facto violation because Brown was not subjected to greater punishment by the retroactive application of the amendments. See United States v. Kimler, 167 F.3d 889, 893 (5th Cir.1999). Finally, Brown has identified no factual disputes that required an evi-dentiary hearing.

The judgment of the district court is AFFIRMED. 
      
       Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir R. 47.5.4.
