MEMORANDUM **

Federal prisoner Jimmy Quan appeals pro se from the district court’s judgment denying, in part, his 28 U.S.C. § 2241 ha-beas petition. We have jurisdiction under 28 U.S.C. § 2253, and we affirm.

The Bureau of Prisons (BOP) contends that the district court lacked jurisdiction to consider Quan’s petition under 28 U.S.C. § 2241. This contention fails because Quan currently challenges the manner in which his sentence was executed. See Tucker v. Carlson, 925 F.2d 330, 331 (9th Cir. 1991) (stating that challenges to the manner in which a sentence was executed are maintainable only in habeas petitions filed under § 2241); see also Rodriguez v. Smith, 541 F.3d 1180 (9th Cir. 2008) (granting a petition filed under § 2241 that challenged a BOP policy regarding the transfer of inmates to Residential Re-entry Centers),

Quan contends that the BOP continues to categorically refuse to consider placing prisoners in Residential Re-entry Centers (RRC) prior to their final six months of incarceration, in violation of 18 U.S.C. §§ 3621(b), 3624(c), and Rodriguez. This contention fails because Quan has not presented any evidence to support this claim.

*183 Quan also contends that, under § 3621(b) and Rodriguez, the BOP is required to immediately assess him for placement in an RCC. This contention fails because § 3621(b) provides the BOP with discretionary authority to consider RCC placement for inmates prior to the last ten percent of the prison term. See Rodriguez, 541 F.3d at 1182-85.

Finally, Quan contends that the BOP is required to consider placing him in an RCC for the last ten percent of his sentence. While a true statement of law, see id. at 1184, Quan does not present any basis for relief because Quan concedes that he is not yet serving the last ten percent of the prison term. See 18 Unnamed “John Smith” Prisoners v. Meese, 871 F.2d 881, 882-83 (9th Cir. 1989) (controversy required for claim to be ripe).

AFFIRMED.
