Okla. Stat. tit. 45, § 45-740.6: Liens

A. Within six (6) months after the completion of projects to

restore, reclaim, abate, control or prevent the adverse effects of

past mining practices on privately owned land, the Commission shall

itemize the monies so expended and may file a statement of the

monies spent with the clerk of the county in which the land lies,

together with a notarized appraisal by an independent appraiser of

the value of the land before the restoration, reclamation,

abatement, control or prevention of adverse effects of past mining

practices if the monies so expended result in a significant increase

in property value. The statement shall constitute a lien on the

land. The lien shall not exceed the amount determined by either of

two appraisals to be the increase in the market value of the land as

a result of the restoration, reclamation, abatement, control or

prevention of the adverse effects of past mining practices. No lien

shall be filed against the property of any person, in accordance

with this subsection, who owned the surface prior to May 2, 1977,

and who neither consented to nor participated in nor exercised

control over the mining operation that necessitated the reclamation

performed hereunder.

B. Any affected landowner may petition the Commission within

sixty (60) days of the filing of the lien for a hearing concerning

the amount of the lien. That hearing and any appeal will be

conducted under the provisions of Sections 301 et seq. of Title 75.
