Oregon Revised Statutes Mineral Resources § 517.865

(1) If an operator fails to faithfully perform the reclamation required by the reclamation plan and if the bond or security required by ORS 517.810 is not sufficient to compensate the State Department of Geology and Mineral Industries for all reasonably necessary costs and expenses incurred by it in reclaiming the surface-mined land, the amount due shall be a lien in favor of the department upon all property, whether real or personal, belonging to the operator. However, for any operator that is first issued a permit after June 30, 1989, the lien shall not exceed $2,500 for each site plus $1,500 per acre.

(2) The lien shall attach upon the filing of a notice of claim of lien with the county clerk of the county in which the property is located. The notice of lien claim shall contain a true statement of the demand, the insufficiency of the bond or security to compensate the department and the failure of the operator to perform the reclamation required.

(3) The lien created by this section is prior to all other liens and encumbrances, except that the lien shall have equal priority with tax liens.

(4) The lien created by this section may be foreclosed by a suit in the circuit court in the manner provided by law for the foreclosure of other liens on real or personal property.
