David Aonzo, federal prisoner # 44847-177, seeks leave to proceed in forma pau-peris (“IFP”) on appeal of the denial of his 18 U.S.C. § 3582(c)(2) motion to reduce his sentence based on retroactive amendment 782 to U.S.S.G. § 2D1.1. By moving to proceed IFP, Aonzo is challenging the district court’s certification 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).

Under § 3582(c)(2), a sentence may be modified if it is based on a sentencing range that subsequently was lowered by the Sentencing Commission. The district court did not err in concluding that Aon- *271 zo’s range was not lowered by amendment 782.

Alonzo 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, the motion to proceed IFP is DENIED, and the appeal is DISMISSED. See Baugh, 117 F.3d at 202 n. 24; 5th Cir. R. 42.2.
