OPINION

Chad Gilmore, a prisoner incarcerated at the Federal Correctional Institution in Fairton, New Jersey, appeals pro se the order of the United States District Court for the District of New Jersey denying his habeas petition filed pursuant to 28 U.S.C. § 2241. For the reasons that follow, we will summarily affirm the District Court’s order.

According to his § 2241 petition, Gilmore pled guilty to receipt of child pornography in the United States District Court for the District of Maryland. On January 27, 2003, Gilmore was sentenced to 32 months’ imprisonment, to be followed by three years of supervised release. The Bureau of Prisons (“BOP”) has calculated that Gilmore is eligible under 18 U.S.C. § 3624(b) to earn up to 125 days of good conduct time.

In February 2005, Gilmore filed the un-, derlying § 2241 petition in the District Court for the District of New Jersey. In his petition, Gilmore alleged that the BOP misinterpreted § 3624(b), depriving him of 19 days of good conduct time. Specifically, Gilmore argued that § 3624(b) allows him to earn up to 54 days per year of the term of sentence imposed, not 54 days per year of time actually served as the BOP’s calculation provides. By order entered March 1, 2005, the District Court denied Gilmore’s petition. This timely appeal followed.

The outcome of this appeal is controlled by our recent decision in O’Donald v. Johns, 402 F.3d 172 (3d Cir. 2005). In O’Donald, 402 F.3d at 174, we held that the meaning of § 3624(b) is ambiguous, and thus deferred to the BOP’s reasonable interpretation of the statute. Gilmore’s claim, identical to that raised and rejected in O’Donald, is unavailing. In short, for the reasons described in O’Donald, the District Court properly rejected Gilmore’s challenge to the BOP’s calculation of his good conduct time.

Because this appeal presents “no substantial question,” 3d Cir. LAR 27.4 and I.O.P. 10.6, we will summarily affirm the District Court’s March 1, 2005, order.
