The director may, before the proposed date for commencing any abandonment operation, approve by order in writing, or, if found to be necessary, approve orally to be followed within forty-eight (48) hours by a written approval order, or disapprove by order in writing, any proposed abandonment. An approval order may be made conditional or limited. Any conditional or limited approval order and any disapproval order shall be accompanied by requests for further tests or other practices than those proposed by the person seeking approval, which tests or practices would remove the disability from the proposed abandonment.
