#### Jose Abel MARTINEZ, Petitioner-Appellant, v. A.M. FLOWERS, Respondent-Appellee.

No. 98-6241.

United States Court of Appeals, Tenth Circuit.

Dec. 14, 1998.

*1258Jose Abel Martinez, pro se.

Before BALDOCK, EBEL, and MURPHY, Circuit Judges.*

*

 After examining the briefs and appellate record, this panel has determined unanimously that oral argument would not materially assist the determination of this appeal. *See*Fed. R.App. P. 34(a)(2); 10th Cir. R. 34.1.9. The case is therefore ordered submitted without oral argument.

BALDOCK, Circuit Judge.

Petitioner Jose Abel Martinez appeals the district court’s denial of his 42 U.S.C. § 2241 petition for habeas corpus relief. He also seeks to proceed on appeal in forma pauperis. Petitioner, an inmate at the Federal Correctional Institution in El Reno, Oklahoma, alleges that the Bureau of Prisons (hereafter “BOP”) wrongfully refused to grant him a one year statutory sentence reduction upon his completion of a residential substance abuse treatment program at FCI El Reno. *See*18 U.S.C. § 3621(e)(2)(B). Our jurisdiction arises under 28 U.S.C. § 1291. We review de novo the district court’s denial of habeas corpus relief. *See Kell v. United States Parole Comm’n,*26 F.3d 1016, 1019 (10th Cir.1994). The district court’s factual findings are reviewed for clear error. *See Matthews v. Price,*83 F.3d 328, 331 (10th Cir.1996). Granting Petitioner’s request to proceed in forma pauperis, we affirm.

I.

In 1995, Petitioner was convicted of conspiracy to possess with intent to distribute and distribution of methamphetamine, in violation of 21 U.S.C. §§ 841(a)(1), (b)(1)(A) and § 846. The district court sentenced him to ten years imprisonment and a five-year term of supervised release. On March 14, 1996, Dr. Robert Johnson, FCIEI Reno drug abuse program coordinator, interviewed Petitioner to determine his eligibility for participation in a substance abuse treatment program. As an incentive for completing substance abuse treatment, § 3621(e)(2)(B) of the Violent Crime Control and Law Enforcement Act of 1994 provides that “[t]he period a prisoner convicted of a nonviolent offense remains in custody after successfully completing a [substance abuse] treatment program may be reduced by the Bureau of Prisons [by] one year from the term the prisoner must otherwise serve.” Petitioner concedes that at the time of his interview, Dr. Johnson informed him that he was ineligible for § 3621(e) early release. Nonetheless, Petitioner began the residential treatment program on June 12, 1996, completing it on March 21,1997. After completion, Petitioner filed an administrative complaint seeking the one year sentence reduction. The BOP denied the reduction under Program Statement 5330.10 and 28 *1259C.F.R. § 550.58, because Petitioner had an INS detainer against him and, as a result, would be unable to complete a community based program.

After the BOP denial, Petitioner filed for habeas corpus relief in district court. The district court referred the petition to a United States Magistrate for preliminary review pursuant to 28 U.S.C. § 636(b)(1)(B). The magistrate judge issued a report recommending dismissal of the petition. On May 13,1998, the district court adopted the report and recommendation and dismissed the petition.

II.

Petitioner argues that upon completion of the residential drug treatment program, he should have been granted a one-year reduction in sentence pursuant to § 3621(e). On appeal, Petitioner argues that: (1) amended versions of BOP Program Statement 5330.10 and 28 C.F.R. § 550.58 were improperly retroactively applied to him to exclude him from § 3621(e) early release; (2) in promulgating § 550.58, BOP exceeded its statutory authority; and (3) BOP’s decision to deny the sentence reduction violated his equal protection rights under the Fifth Amendment. We reject Petitioner’s arguments as set forth below.

A.

Petitioner correctly notes that in May 1996, 28 C.F.R. § 550.58 and Program Statement 5330.10 were amended to exclude from the sentence reduction program individuals who could not complete a community-based treatment program. Anended § 550.58 provides in relevant part that inmates “who are not eligible for participation in a community-based program” are not eligible for early release. 28 C.F.R. § 550.58 (as amended May 1996).1 Athough BOP ostensibly based its decision to deny Petitioner’s appeal on this portion of the amended version of § 550.58, we need not decide whether BOP could apply this amendment retroactively, because regardless of which version of § 550.58 BOP applied to Petitioner, he was excludable from the early release program on another ground. Both the original and amended versions of § 550.58 exclude individuals from early release who had previous convictions for “homicide, forcible rape, robbery, or aggravated assault.”2 Because Petitioner had a prior state conviction for vehicular manslaughter with gross negligence, a homicide under California law, he was ineligible for early release under either the original or amended version of 28 C.F.R. § 550.58.3

B.

Petitioner argues that in adopting 28 C.F.R. § 550.58, BOP exceeded its statutory authority. In reviewing an agency’s interpretation of a statute through a formal regulation, we defer to the agency’s interpretation if it is based on a permissible construction of the statute. *See Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc.,*467 U.S. 837, 843, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984); *Fristoe v. Thompson,*144 F.3d 627, 631 (10th Cir.1998). If the statutory language is ambiguous or silent on the issue, the agency’s regulation receives “controlling weight unless they are arbitrary, capricious, or manifestly contrary to the statute.” *Chevron,*467 U.S. at 844, 104 S.Ct. 2778.

Section 3621(e)(2)(B) allows BOP to reduce an inmate’s sentence by one year if the “prisoner [was] convicted of a nonviolent offense.” In order to implement § 3621(e)(2)(B), BOP promulgated § 550.58 which lists certain categories of inmates who are excluded from sentence reduction. The excluded categories include inmates such as Petitioner, “who have a prior conviction for homicide, forcible rape, robbery, or aggravated assault.” The statute is silent as to whether BOP may consider a prisoner’s past convictions or only the most recent one in determining eligibility for a sentence reduc*1260tion. Therefore, we must uphold the agency-regulation unless it is “arbitrary, capricious, or manifestly contrary to the statute.”

We have not previously considered the validity of this particular § 3621(e)(2)(B) eligibility requirement. Three other circuits, however, have addressed this question, and upheld the regulation, concluding that BOP may permissibly exclude inmates from the early release program, if they have prior convictions for a violent offense. *See Wottlin v. Fleming,*136 F.3d 1032 (5th Cir.1998); *Stiver v. Meko,*130 F.3d 574 (3rd Cir.1997); *Jacks v. Crabtree,*114 F.3d 983 (9th Cir.1997), ce*rt. denied,*— U.S. -, 118 S.Ct. 1196, 140 L.Ed.2d 325 (1998).

The statute states that the sentence of an inmate “convicted of a non-violent offense ... *may*be reduced by the Bureau of Prisons.” § 3621(e)(2)(B) (emphasis added). Absent from this language is a modifier which limits the non-eligibility criteria to the present conviction. The statute does not restrict the non-violent requirement to the “current” or “instant” conviction. In addition, the statute’s language grants broad discretion to BOP to grant or deny the one-year sentence reduction. In *Jacks v. Crabtree,*the Ninth Circuit reasoned that the unrestrictive language of the statute, coupled with the broad discretion granted to BOP by the statute, allowed BOP to promulgate a” regulation excluding inmates with prior convictions for violent crimes from early release. 114 F.3d at 986; *see also Bush v. Pitzer,*133 F.3d 455, 458 (7th Cir.1997) (“a prisoner whose offense is ‘nonviolent’ but whose underlying conduct is violent or prone to violence rationally can be excluded from the [early release] program”).

Likewise, in *Stiver,*the Third Circuit concluded that BOP’s “interpretation of the statute represents a reasonable accommodation of Congress’ goals of providing an incentive for inmates to obtain drug treatment while at the same time ensuring that persons likely to commit violent crimes do not receive early release.” *Stiver,*130 F.3d at 577. It would be inconsistent with Congress’ goal of limiting early release to nonviolent offenders, to allow individuals with a history of violent crimes to receive the one-year sentence, reduction merely because their latest conviction was for a non-violent crime. For these reasons, we agree with our sister circuits and uphold BOP’s promulgation of § 550.58.

Our decision does not conflict with a recent Tenth Circuit decision striking down a different eligibility requirement under § 3621(e)(2)(B). In *Fristoe v. Thompson,*144 F.3d 627 (10th Cir.1998), we held that the adoption of Program Statement 5162.02, which allowed consideration of sentencing factors, as well as the crime of conviction, to determine whether an inmate was eligible for a § 3621(e)(2)(B) sentence reduction, exceeded BOP’s statutory authority. The program statement provided that convictions obtained under 21 U.S.C. § 841 or § 846 should be considered crimes of violence “if the sentencing court increased the base level of the sentence for possession of a dangerous weapon during the commission of the offense.” *Fristoe,*144 F.3d at 629-30. In striking down the program statement, we first noted that courts “typically do -not consider the predicate drug offense, conspiracy to distribute, a crime of violence.” *Id.*at 631. Thus, the classification of Fristoe’s crime as “violent” rested entirely upon the sentencing factors. - *Id.*We held that such reliance conflicted with the plain language of the statute which refers to prisoners *“convicted*of a nonviolent offense.” (emphasis added). *Id.*We reasoned that § 3621(e)(2)(B) simply does not authorize BOP to treat sentence enhancements or factors as if they were “convictions.” *Id.*at 632. In other words, if the prisoner has not.been convicted of a violent offense, BOP cannot use sentencing factors or enhancements to convert a nonviolent offense into a violent one for purposes of § 3621(e)(2)(B).

The program statement at'issue in *Fristoe*differs from the regulation at issue in this case in two significant ways. First, § 550.58 explicitly requires that an inmate must have been previously *convicted*of a violent crime in order to be ineligible for the sentence reduction. Importantly, unlike the program statement at issue in *Fristoe,*§ 550.58 looks to inmates’ actual criminal convictions and does not attempt to convert something else, such as a sentencing enhancement, into a conviction. *See Jacks,*114 F.3d at 985. Thus, this case does not present the proble*1261matic denial of sentence reductions to inmates who have *never*been convicted of a violent crime because § 550.58 only excludes those inmates previously *convicted*of “homicide, forcible rape, robbery, or aggravated assault....”

Second, Fristoe is distinguishable from the present case because of the different legal analyses we apply to formal versus informal agency interpretations of statutes. A formal regulation is entitled to deference under *Chevron*and receives “controlling weight unless arbitrary, capricious or manifestly contrary to the statute.” *Chevron,*467 U.S. at 844, 104 S.Ct. 2778. Unlike a formal regulation, an informal program statement is not entitled to *Chevron*deference. *See Fristoe,*144 F.3d at 631. Instead, we consider whether the program statement is a well reasoned interpretation of the statute which has the “ ‘power to persuade.’ ” *Id.*(quoting *Skidmore v. Swift & Co.,*323 U.S. 134, 140, 65 S.Ct. 161, 89 L.Ed. 124 (1944)). In *Fris-toe*we applied the less deferential standard when we invalidated the program statement. In contrast, in this case we owe § 550.58 full *Chevron*deference. Consequently, *Fristoe*does not control the outcome of the instant case.

C.

Petitioner’s remaining equal protection argument is ineffectual at best. Petitioner argues that he was treated differently from other prisoners who have been granted sentence reductions. We review the government’s classification of inmates with prior violent crime convictions under a rational basis standard, as no suspect class or fundamental right is implemented. *See Wottlin,*136 F.3d at 1036 (reviewing § 550.58 under “rational basis” standard); *see Greenholtz v. Inmates of the Nebraska Penal & Correctional Complex,*442 U.S. 1,7, 99 S.Ct. 2100, 60 L.Ed.2d 668 (1979) (a convicted prisoner does not have a constitutional right to be released before the expiration of á valid sentence); *see also Shifrin v. Fields,*39 F.3d 1112, 1114 (10th Cir.1994) (violent offenders are not a suspect class). Under this standard, we uphold a classification if it is rationally related to a legitimate government interest. *See White v. State of Colorado,*157 F.3d 1226, 1234 (10th Cir.1998).

When enacting the sentence reduction statute, Congress balanced the goal of providing inmates with an incentive to participate in substance abuse treatment with the need to ensure that violent offenders were not given early release. Section 550.58 furthers the legitimate governmental purpose of the statute by limiting early release to nonviolent offenders. Thus, we conclude that the regulation’s treatment of inmates with prior convictions for violent crimes is rationally related to the legitimate governmental end of preventing the early release of potentially violent inmates. Consequently, BOP’s application of this regulation to Petitioner did not violate his right to equal protection. *See Wottlin,*136 F.3d at 1037.

AFFIRMED.

.The record also does not support a retroactivity argument. Petitioner entered the drug treatment' program in June 1996, one month *after*the amended version of § 550.58 went into effect.
