Oregon Revised Statutes Public Health and Safety § 459.108

(1) A city or county may impose a civil penalty to enforce the requirements of an ordinance that prohibits any action or conduct described in ORS 164.775, 164.785 or 164.805.

(2) An ordinance described in subsection (1) of this section may establish a maximum or minimum amount for the civil penalty imposed under the ordinance for each violation. The total amount of the civil penalty may be increased to include all of the costs incurred by the city or county in removing the refuse or offensive substance unlawfully placed on property and in eliminating the effects of such unlawful placement.

(3) A civil penalty imposed for violation of an ordinance prohibiting any action or conduct described in ORS 164.775, 164.785 or 164.805 shall be an alternative to criminal enforcement of the ordinance. A city or county that commences and maintains a civil action to collect such a civil penalty from any person shall not cause a criminal prosecution to be commenced or maintained against that person for the same violation of the ordinance.

(4) When a city or county ordinance prohibits any action or conduct that is described in ORS 164.775, 164.785 or 164.805, a name found on various items in a deposit of rubbish or other solid waste placed on land or in water in violation of the ordinance constitutes rebuttable evidence that the person whose name appears on the items has violated the ordinance. However, the rebuttable presumption created by this subsection exists only when a name on items denotes ownership of the items, such as the name of an addressee on an envelope.
