MEMORANDUM

California state prisoner Patrick James Carrizosa, Jr., appeals pro se from the district court’s judgment denying his 28 U.S.C. § 2254 habeas petition. We have jurisdiction under 28 U.S.C. § 2253 , and we affirm.

Carrizosa contends that the State’s failure to award him day-for-day sentence credits violated his due process rights. However, Cal.Penal Code § 2933.1 limits the sentence credits Carrizosa may earn through his participation in the Inmate Work Training Incentive Program to fifteen percent. The other state statutes and regulations cited by Carrizosa do not create a protected due process liberty interest in sentence credits. See Sandin v. Conner, 515 U.S. 472, 483-85 , 115 S.Ct. 2293 , 132 L.Ed.2d 418 (1995); McLean v. Crabtree, 173 F.3d 1176, 1184-85 (9th Cir.1999).

To the extent Carrizosa challenges the state court’s application of state law concerning equitable estoppel, this contention does not state a cognizable claim of a violation of federal law. See Lewis v. Jeffers, 497 U.S. 764, 780 , 110 S.Ct. 3092 , 111 L.Ed.2d 606 (1990) (“[Fjederal habeas corpus relief does not lie for errors of state law[.]”). Furthermore, the district court correctly rejected Carrizosa’s government estoppel argument on the merits.

Finally, the district court properly rejected Carrizosa’s equal protection claim. The record reflects that the documentary evidence submitted by Carrizosa did not establish that he was treated differently from similarly situated individuals. See McLean, 173 F.3d at 1185 .

Thus, the California courts’ rejection of Carrizosa’s claims was neither contrary to nor an unreasonable application of clearly established federal law. See 28 U.S.C. § 2254 (d)(1). Moreover, because Carrizo-sa failed to raise a colorable claim for relief, see Phillips v. Woodford, 267 F.3d 966, 973 (9th Cir.2001), his contention that he is entitled to an evidentiary hearing on his claims lacks merit.

AFFIRMED.

This disposition is not appropriate for publication and is not precedent except as provided by 9th Cir. R. 36-3. . We certify for appeal on our own motion the issues presented in this appeal.
