    UNITED STATES of America, Plaintiff-Appellee, v. Edwin Reginald STRAUGHTER, a.k.a. Pooh, Defendant-Appellant.
    No. 08-11943
    Non-Argument Calendar.
    United States Court of Appeals, Eleventh Circuit.
    Dec. 16, 2008.
    Madeleine R. Shirley, Anne R. Schultz, Lisa A. Hirsch, U.S. Attorney’s Office, Miami, FL, for Plaintiff-Appellee.
    Edwin Reginald Straughter, Coleman, FL, pro se.
    
      Before CARNES, BARKETT and KRAVITCH, Circuit Judges.
   PER CURIAM:

Edwin Reginald Straughter, a federal prisoner proceeding pro se, appeals the district court’s denial of his motion to reduce his four concurrent life sentences under 18 U.S.C. § 3582(c)(2). The district court denied the motion because it found that Straughter was sentenced as a career offender, under U.S.S.G. 4B1.1, two of the underlying offenses called for a mandatory minimum life sentence, and, accordingly, Amendment 706 to the Sentencing Guidelines did not change his guideline range.

Although Straughter concedes that he was sentenced as a career offender, he argues that he still was eligible for a sentence reduction based on Amendment 706 to the Guidelines, Booker , and Booker*s progeny. “In a proceeding to modify a sentence under 18 U.S.C. § 3582(c)(2), we review de novo the district court’s legal conclusions regarding the scope of its authority under the Sentencing Guidelines.” United States v. White, 305 F.3d 1264, 1267 (11th Cir.2002). We review for an abuse of discretion a district court’s decision whether to reduce a sentence pursuant to § 3582(c)(2). Id.

Under § 3582(c)(2), a district court has discretion to reduce the term of imprisonment of an already incarcerated defendant if that defendant “has been sentenced to a term of imprisonment based on a sentencing range that has subsequently been lowered by the Sentencing Commission pursuant to 28 U.S.C. § 994(o).” 18 U.S.C. § 3582(c)(2). In such a case, the court may reduce the defendant’s sentence, after considering applicable § 3553(a) factors, “if such a reduction is consistent with applicable policy statements issued by the Sentencing Commission.” Id.

The Sentencing Commission’s policy statement on retroactive reduction of sentences, U.S.S.G. § 1B1.10, provides that:

In a case in which a defendant is serving a term of imprisonment, and the guideline range applicable to that defendant has subsequently been lowered as a result of an amendment to the Guidelines Manual listed in subsection (c) below, the court may reduce the defendant’s term of imprisonment as provided by 18 U.S.C. § 3582(c)(2), and any such reduction in the defendant’s term of imprisonment shall be consistent with this policy statement.

U.S.S.G. § lB1.10(a)(l). However, a reduction in the term of imprisonment is not consistent with the Guidelines policy statement, and therefore not authorized by § 3582(c)(2), if “an amendment listed in subsection (c) does not have the effect of lowering the defendant’s applicable guideline range.” U.S.S.G. § lB1.10(a)(2)(B); see also United States v. Armstrong, 347 F.3d 905, 909 (11th Cir.2003) (stating that only retroactively applicable amendments “that have the effect of lowering the sentencing range upon which a sentence was based, may be considered for reduction of a sentence under § 3582(c)(2)”). Accordingly, a sentence reduction is not authorized where an amendment “is applicable to the defendant but ... does not have the effect of lowering the defendant’s applicable guideline range because of the operation of another guideline or statutory-provision (e.g. a statutory mandatory minimum term of imprisonment).” U.S.S.G. § 1B1.10, comment, (n. 1(A)).

Amendment 706, which is listed in U.S.S.G. § lB1.10(c), was made retroactive by Amendment 713. See U.S.S.G.App. C, Amend. 713 (Supp. May 1, 2008); U.S.S.G. § 1B1.10(c) (Supp. May 1, 2008); see also, United States v, Stratton, 519 F.3d 1305, 1307 (11th Cir.2008). Amendment 706 reduced offense levels in certain crack cocaine cases by two levels, as reflected in the drug quantity table in U.S.S.G. § 2Dl.l(c). See U.S.S.GApp. C, Amend. 706 (2007). Nevertheless, Amendment 706 does not serve as a basis for a sentence reduction if, based on the operation of another guideline or statutory provision, it does not lower a defendant’s guideline range. U.S.S.G. § 1B1.10, comment. (n.l(A)).

In United States v. Moore, 541 F.3d 1323 (11th Cir.2008), we recently held that defendants sentenced as career offenders under U.S.S.G. § 4B1.1 typically are not eligible for a sentence reduction under § 3582(c)(2) based on Amendment 706 because the Amendment would not affect their guideline ranges, even though it reduced the base offense levels. Moore, 541 F.3d at 1330. Similarly, we have also held that defendants sentenced as armed career criminals under U.S.S.G. § 4B1.4 are not eligible for a sentence reduction under § 3582(c)(2). United States v. Thomas, 545 F.3d 1300, 1302 (11th Cir.2008); see also United States v. James, 548 F.3d 983, 985-86 (11th Cir.2008) (holding that defendant was not entitled to a § 3582(c)(2) sentence reduction when, based on the amount of crack and powder cocaine he was responsible for and an intervening change in the Guidelines, his offense level was higher under Amendment 706 than when he was sentenced).

Straughter was ineligible for a sentence reduction under § 3582(c)(2) because, although Amendment 706 may have reduced his crack cocaine base offense level, it did not affect his final guideline range, which was based on the career offender enhancement. Likewise, in regards to counts one and five, Straughter was ineligible for a sentence reduction because the guideline range for those charges was based on the mandatory statutory life sentence, under U.S.S.G. § 5Gl.l(b).
