Jorge A. Duarte pleaded guilty and was convicted of conspiracy to possess with the intent to distribute marijuana. The district court sentenced him to 70 months of imprisonment, four years of supervised release, and a $100 special assessment.

Duarte argues that he was wrongly denied a downward adjustment for his minor or minimal role in the offense. The advisory Sentencing Guidelines provide for a reduction in the base offense level of a “minor” or a “minimal” participant. U.S.S.G. § 3B1.2. To merit a reduction under § 3B1.2, the defendant must have been “substantially less culpable” than the average participant. § 3B1.2, comment. (n.3(A)). “The defendant bears the burden of establishing that he is eligible for the adjustment.” United States v. Partida, 385 F.3d 546, 566 (5th Cir.2004).

The presentence report indicates that Duarte was one of many lower-level participants in a drug trafficking organization. He participated for an extended period of time in activities such as conducting counter-surveillance to monitor law enforcement activity, driving loads of marijuana, and general loading and unloading of marijuana. Duarte has not shown that he is substantially less culpable than the average participant in the conspiracy, given that there were many lower-level participants such as himself. See § 3B1.2, comment. (n.3(A)). He has also not shown that his participation was “peripheral to the advancement of the illicit activity” or that his participation was not “critical to the offense.” United States v. Villanueva, 408 F.3d 193, 204 (5th Cir.2005); United States v. Tremelling, 43 F.3d 148, 153 (5th Cir.1995). We find no reversible error in the district court’s denial of a reduction under § 3B1.2.

AFFIRMED.
