(b) Applications under this section shall contain the following with respect to the proposed operating plan:
(i) Evidence that groundwater in the proposed formation intervals will not be adversely influenced by the injections and that the operations shall at all times be in compliance with applicable groundwater quality regulations and underground injection control program requirements.

(B) Obtaining a class V well permit from the Wyoming department of environmental quality.
(c) Upon the filing of an application under this section, the commission shall promptly set the matter for hearing. In addition to any notice required by law or commission rules, the commission shall give notice of the hearing by certified mail to all persons owning or having an interest in coal or its production in the proposed application area. The notice shall be mailed at least thirty (30) days before the hearing, shall specify the time and place of hearing and shall describe briefly the purpose of the hearing and the land affected.
(d) Following the hearing, the commission shall enter an order setting forth findings and approving the application if the commission finds that the provisions of W.S. 30-5-109 or 30-5-110 have been met.
