UNITED STATES COURT OF APPEALS

TENTH CIRCUIT

JEFFREY JON PEVEHOUSE, 		
		Petitioner-Appellant,	No. 06-6378	
	v.	(Case No. CIV-05-1363-R)	
JOSEPH SCIBANA, 	(W.D. Okla.)	
		Respondent-Appellee.		

ORDER AND JUDGMENT*	After examining the briefs and the appellate record, this panel has determined unanimously that oral argument would not be of material assistance in the determination of this appeal.  See Fed. R. App. P. 34(a)(2); 10th Cir. R. 34.1(G).  The case is therefore ordered submitted without oral argument.

Before BRISCOE, McKAY, and McCONNELL, Circuit Judges.

	Petitioner, a federal prisoner proceeding pro se, appeals the district court’s denial of his 28 U.S.C. § 2241 petition.  In his § 2241 petition, Petitioner argued that he was entitled to federal sentence credit for the time he spent in custody between February 23, 2001, when he was arrested by state authorities, and November 13, 2001, when he began serving his federal sentence.  After proceedings had begun in the district court, the Bureau of Prisons awarded Petitioner federal sentence credit for the eighteen days between February 23, 2001, and March 13, 2001.  Thus, only the period between March 13, 2001, and November 13, 2001, remains in dispute.
	Reviewing de novo, see Patterson v. Knowles, 162 F.3d 574, 575 (10th Cir. 1998), we affirm.  Petitioner received credit on his state sentence for all of the time between March 13, 2001, and November 13, 2001, when his federal sentence commenced.  A federal prisoner is only entitled to credit for time spent in official detention prior to commencement of his federal sentence if that time has not been credited against another sentence.  18 U.S.C. § 3585(b); see also United States v. Wilson, 503 U.S. 329, 337 (1993); Weekes v. Fleming, 301 F.3d 1175, 1179 (10th Cir. 2002).  Therefore, Petitioner is not entitled to federal sentence credit for the time credited to his state sentence.
	As for Petitioner’s argument that § 3585(b) is unconstitutional, the district court correctly held that he had waived this argument by failing to raise it before the magistrate.  See Marshall v. Chater, 75 F.3d 1421, 1426 (10th Cir. 1996).   Accordingly, we AFFIRM the district court’s dismissal of the action.  Petitioner’s motion for leave to proceed in forma pauperis is GRANTED.
