1. During the term of the permit the permittee may submit an application for a revision of the permit, together with a revised operations plan and reclamation plan, to the Director.

2. An application for a revision of a permit shall not be approved unless the Director finds that reclamation as required by the federal act and the permanent state regulatory program can be accomplished under the revised reclamation plan. The Director shall establish, by regulation, the period of time within which the revision shall be approved or disapproved, as well as guidelines for a determination of the scale or extent of a revision request for which all permit application information requirements and procedures, including notice and hearings, shall apply; however, any revisions which propose significant alterations in the operations plan and reclamation plan shall, at a minimum, be subject to notice and hearing requirements.

3. Any extension to the area covered by the permit, except insignificant boundary revisions, must be made by application for another permit.
