(a) For surface coal mining operations, this Chapter does not apply to extensions of the mine permit boundary. Any such extension, except incidental boundary revisions, must be made in accordance with the Act and by application for a permit amendment with public notice, and opportunity for hearing. The operator shall notify the Administrator in advance where the extension is an incidental boundary revision, and possess a copy of the notification at the site of the operation. The operator will not be allowed to utilize this provision for incidental boundary revisions so as to circumvent the policy and purpose of this Chapter and the Wyoming Environmental Quality Act.
