Oregon Revised Statutes Public Lands § 275.314

Each application presented to the governing body of the county under ORS 275.312 must be accompanied by evidence satisfactory to the governing body of the county showing that the applicant is the owner of the surface rights to the lands described in the application, and also by a cash deposit or an irrevocable letter of credit issued by an insured institution as defined in ORS 706.008 in an amount sufficient to reimburse the county for all costs of such transfer, including but not limited to the costs of investigation and legal work, which shall be paid by the applicant. The governing body of the county then shall cause an investigation to be made by qualified geologists or mining engineers in regard to the probable value of such mineral rights. If the governing body of the county finds that such rights are of little or doubtful value and that it would be in the best interests of the county to transfer such rights to the owner of the surface rights, the governing body of the county may make and enter an order declaring its intention to make such transfer and setting a time and place for hearing objections thereto. The time for the hearing shall be set not earlier than six weeks after the date of the order.
