(2)(a) The Department of Revenue shall appraise each state-appraised industrial property situated within each county and advise the county assessor of the real market value of the property and the property's net improvements. Except as provided in subsection (3) of this section, no part of the cost of the appraisal shall be borne by the county. The cost of the appraisal shall be reimbursed from the County Assessment Function Funding Assistance Account as provided under ORS 294.184.

(b) The department shall advise the assessor of the values determined under this subsection by a date that is determined to give the assessor sufficient time to prepare the assessment roll.

(b) A request by the county assessor under this subsection must be made prior to January 1 for the following assessment year and must be accompanied by any information required by the department.

(c) If responsibility is delegated under this subsection, the entire cost of making the appraisals delegated shall be borne by the county.

(d) No appeal may be taken from any determination of the department under this subsection.

(4)(a) Once the responsibility for making appraisals of a state-appraised industrial property is delegated to the county assessor under subsection (3) of this section, the property shall remain a county-appraised industrial property for five consecutive assessment years.

(b) After five consecutive assessment years, the industrial property shall remain a county-appraised industrial property until the county assessor requests the department to resume responsibility for appraising the property. Upon the request of the county assessor, the property shall revert to a state-appraised industrial property as of the next following assessment year.
