    UNITED STATES of America, Plaintiff—Appellee, v. Michael Dennis OLDS, Defendant—Appellant.
    No. 03-6934.
    United States Court of Appeals, Fourth Circuit.
    Submitted Sept. 10, 2003.
    Decided Feb. 10, 2004.
    Michael Dennis Olds, Appellant pro se. John Samuel Bowler, Assistant United States Attorney, Raleigh, North Carolina, for Appellee.
    Before LUTTIG, TRAXLER, and GREGORY, Circuit Judges.
    Affirmed by unpublished PER CURIAM opinion.
    Unpublished opinions are not binding precedent in this circuit. See Local Rule 36(c).
   PER CURIAM.

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 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 
      
       Olds does not challenge the district court’s denial of his motion for reconsideration in his informal brief filed in this court. He therefore has waived appellate review of that order. See 4th Cir. R. 34(b).
