Oregon Revised Statutes Public Health and Safety § 459.215

(1) By rule and after public hearing, the Environmental Quality Commission may prescribe criteria and conditions for excluding classes of disposal sites from the permit requirements of ORS 459.205. Disposal sites so excluded shall be limited to those which, because of the nature or volume of solid waste handled, are not likely to create a public nuisance, health hazard, air or water pollution, or other serious problem. Facilities operated under a permit issued under ORS 468B.050 or 468B.053 are not required to obtain a permit from the Department of Environmental Quality pursuant to ORS 459.205. However, exclusion from the permit requirements of ORS 459.205 does not relieve any person from compliance with other requirements of ORS 459.005 to 459.105 and 459.205 to 459.385 and the rules and regulations adopted pursuant thereto.

(2) By rule and after public hearing the commission may establish classes of disposal sites that qualify for exclusion under this section.
