PER CURIAM:

Jamal Siddq Rickenbacker pled guilty to distribution of cocaine base and possession of a firearm by a convicted felon. He was sentenced within his advisory Guidelines range to 168 months in prison. On appeal, his attorney has filed a brief pursuant to Anders v. California, 386 U.S. 738 (1967), concluding that there were no meritorious issues for appeal but questioning whether the Government acted in bad faith by moving for only a one-level departure under U.S. Sentencing Guidelines Manual § 5K1.1 (2009). Although informed of his right to do so, Rickenbacker has not filed a pro se supplemental brief. The Government has moved to dismiss the appeal based on Rickenbacker's waiver of appellate rights in his plea agreement. We grant the motion in part and dismiss the appeal with regard to Rickenbacker's sentence. After a review of the record under Anders, we affirm Rickenbacker's convictions.

A defendant may, in a valid plea agreement, waive the right to appeal. United States v. Wiggins, 905 F.2d 51, 53 (4th Cir. 1990). Any such waiver must be made by a knowing and intelligent decision to forgo the right to appeal. United States v. Broughton-Jones, 71 F.3d 1143, 1146 (4th Cir. 1995). Whether a defendant has effectively waived his right to appeal is an issue of law we review de novo. United States v. Marin, 961 F.2d 493, 496 (4th Cir. 1992).

The district court's plea colloquy was thorough, conformed to the dictates of Fed. R. Crim. P. 11, and specifically addressed the appellate waiver. Moreover, Rickenbacker does not challenge the voluntariness of his waiver. Accordingly, the waiver is enforceable.

The waiver expressly precluded Rickenbacker from appealing any sentence within or below the advisory Guidelines range "resulting from an adjusted base offense level of 31." Because the sentence imposed was within the advisory range based upon an offense level of 29, any challenge to the district court's sentence, including Rickenbacker's claim that the Government arbitrarily decided not to move for a larger reduction,* falls within the scope of that waiver. As such, we grant the Government's motion to dismiss Rickenbacker's appeal of his sentence.

However, the waiver's enforceability does not completely dispose of this appeal. Rickenbacker's appellate waiver did not waive his right to appeal his conviction. Though Rickenbacker does not raise a specific challenge to his conviction, pursuant to Anders, we must review the record for any meritorious issues. In accordance with Anders, we have reviewed the entire record and found no viable claims regarding Rickenbacker's conviction.

Accordingly, we affirm Rickenbacker's convictions. This court requires that counsel inform his client, in writing, of his right to petition the Supreme Court of the United States for further review. If the client requests that a petition be filed, but counsel believes that such a petition would be frivolous, then counsel may move this court for leave to withdraw from representation. Counsel's motion must state that a copy thereof was served on the client. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

DISMISSED IN PART; AFFIRMED IN PART.
