Oregon Revised Statutes Agriculture § 571.145

(1) The State Department of Agriculture shall inspect each licensed nursery at least once and as often thereafter as the department considers necessary to determine and control pest, disease and noxious weed conditions.

(2) The department may make additional inspections as necessary for the issuance of phytosanitary and other certificates. Such additional inspections are in addition to normal inspections as provided by subsection (1) of this section. The department may charge for such inspections requested by nurseries in order to issue state or federal phytosanitary certificates and any other certificate that requires inspection prior to issuance of such certificates. Such charge shall not be less than $10 per requested certificate or greater than $50 per such certificate. However, for license years after June 30, 1995, the department may establish the certificate fee without regard to the limitations provided in this subsection after consulting with the State Nursery Research and Regulatory Committee and after holding public hearings in accordance with ORS chapter 183.

(3) The department may establish a schedule of fees for nursery stock inspections and special services which may be performed by the department for persons who are not required to obtain a license pursuant to ORS 571.005 to 571.230 and 571.991. The fees shall be established in such amounts as are reasonably necessary to recover all costs incurred by the department in the performance of such inspections and special services. Payment for such inspections and special services shall be made to the department at the time the inspections or special services are performed.
