Mine permit and reclamation plan changes-landowner approval.

HB 257 requires written consent from surface landowners (who are not the mining operator or mineral owner) before any revisions to mining permits or reclamation plans can be approved by Wyoming's environmental agencies. The bill specifically applies to all mining permits except surface coal mining permits and affects landowners who lease or own land where mining occurs but do not operate the mine. Key provisions mandate that operators must obtain this written landowner approval for any permit or reclamation plan changes, including boundary adjustments or operational modifications. The law became effective July 1, 2023, for all applications submitted after that date.
