Tai Tan Duong, federal prisoner # 04216-078, has appealed the denial of his motion under 18 U.S.C. § 3582(c)(2) for modification of his sentence, in light of Sentencing Guidelines Amendment 591. Because the amendment did not lower the guideline range under which Duong was sentenced, the district court did not have authority under 18 U.S.C. § 3582(c)(2) to reduce his sentence. See United States v. Owens, 72 Fed.Appx. 200, 201 (5th Cir. 2003) (unpulished), cert. denied, — U.S. —, 124 S.Ct. 1525, 158 L.Ed.2d 167 (2004).

Duong contends for the first time on appeal that his sentence was illegal in light of Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000). Apprendi has not been applied retroactively. See United States v. Brown, 305 F.3d 304, 310 (5th Cir. 2002).

Because the appeal is frivolous, it is DISMISSED. See Howard v. King, 707 F.2d 215, 220 (5th Cir. 1983); 5th Cir. R. 42.2.

APPEAL DISMISSED.
