Michael Dennis Olds appeals the district court’s orders denying his motions filed under 18 U.S.C.A. § 3582 (West 2000 & Supp. 2003), and for reconsideration. * We have reviewed the record and find no reversible error. The district court may not modify a sentence under § 3582 once it *657 has been imposed except in very narrow circumstances not applicable here. Because Olds’ claims were not cognizable under § 3582, we affirm the district court’s denial of relief on that basis. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

AFFIRMED
