ORDER AND JUDGMENT *

Candi Jane Sisk pled guilty to conspiring to distribute methamphetamine in violation of 21 U.S.C. § 846. At sentencing, the district court relied on the Presentence Investigation Report (“PSIR”) in decreasing Sisk’s offense level by two based on *833 her role as a minor participant, pursuant to U.S.S.G. § SBl^Cb). 1 Notwithstanding her failure to object below, Sisk challenges on appeal the district court’s determination that she was a minor participant in the drug conspiracy eligible for a two-level reduction, rather than a minimal participant eligible for a four-level reduction. Exercising jurisdiction under 28 U.S.C. § 1291 and 18 U.S.C. § 8742(a), we affirm.

In general, we review for clear error a district court’s factual determination as to whether a defendant was a minor or a minimal participant in a drug conspiracy, and we give due deference to the court’s application of the sentencing guidelines to the facts. United States v. Garcia, 182 F.3d 1165, 1175 (10th Cir. 1999). Because Sisk failed to object to the PSIR’s characterization of her role in the offense as minor, however, she has waived the issue on appeal unless the district court committed plain error. See United States v. Ivy, 83 F.3d 1266, 1297 (10th Cir. 1996) (“We have repeatedly held that if a defendant fails to object to [her] presentence report, [she] waives [her] right to challenge the district court’s reliance on it, unless the district court’s decision to do so amounts to plain error.”). It is well-established that, to constitute plain error, a district court’s decision must be “particularly egregious, as well as obvious and substantial.” Id. (quotation omitted).

Based on our review of the undisputed facts of the instant case, as set forth in the PSIR, it is far from obvious whether Sisk was a minimal versus a minor participant in the conspiracy. As described in the PSIR, Sisk was a “runner” in the drug conspiracy, she had obtained the necessary paraphernalia for the manufacture of methamphetamine, and she was aware of the conspiracy. (13 R. at 17 1159.) Even if the district court erred in concluding that Sisk was a minor, rather than a minimal, participant, its error was not “particularly egregious, obvious, or substantial,” Ivy, 83 F.3d at 1297, so as to constitute plain error. Accordingly, we AFFIRM.

The mandate shall issue forthwith.
