Pursuant to ORS 183.400, petitioner challenges a rule adopted by the Oregon Department of Corrections. He argues that OAR 291-97-020(7), which provides guidelines for the computation of earned-time credits for presentence incarceration, violates Article I, section 20, of the Oregon Constitution, and the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution.1
Our scope of review under ORS 183.4002 is limited to the face of the rule and the law pertinent to it. AFSCME Local 2623 v. Dept, of Corrections, 315 Or 74, 79, 843 P2d 409 (1992). Judicial review of the application of the rule to individual fact situations is reserved to other forums. See, e.g., ORS 183.482; ORS 183.484 (providing for judicial review of agency orders in fact-specific situations).
Petitioner concedes that the rule, on its face, provides that all inmates who are subject to the sentencing guidelines are eligible to receive earned-time credits for the time they spend incarcerated while awaiting sentencing.3 *505Petitioner contends, however, that the Department “says OAR 291-97-020(7) is not retroactive even though all inmates are bound by it.” He argues, as a consequence, that he and other inmates who were incarcerated before the effective date of the rule, June 9,1993, are denied the opportunity to receive earned-time credits for presentence incarceration. He asserts that the Department’s refusal to apply the rule retroactively to him denies him equal treatment in violation of the state and federal constitutions.
The basis for petitioner’s argument is unclear, because the rule does not provide that it applies only prospectively. Even assuming, however, that petitioner’s challenge has some basis in fact, such a challenge would be to the application of the rule to petitioner in a manner that violates the equal treatment guarantees in the state and federal constitutions. Petitioner’s challenge is not to the rule as it is written. Consequently, his challenge is beyond the scope of our review under ORS 183.400.
Rule held valid.
