ORS 153.022

If a statute provides that violation of the rules of an agency constitutes an offense, as described in ORS 161.505, the agency may by rule specify that violation of a specific rule of the agency is subject to a specific fine, or a specific maximum fine, that is less in amount than the maximum fine for the offense specified by the statute. In addition, the agency may specify that violation of the specific rule is a Class A, B, C or D violation under the provisions of ORS 153.012 as long as the class specified in the rule is lower than the statutory classification for the offense.
