(a) Unless waived under (b) below, or prohibited by W.S. 35-11-1206 (West 2009), the Director shall file a lien against the land if the reclamation results in a substantial increase in the land's fair market value based on the appraisals obtained under Section 1.
(b) The Governor may waive the lien if all costs of filing it exceed the fair market value increase, or if the reclamation work primarily benefits health, safety or environmental values of the greater community or area in which the land is located. In addition, the lien may be waived if reclamation is necessitated by an unforeseen occurrence and the reclamation work will not result in a significant increase in the land's fair market value.
