(B) The term of a permit to operate shall not be extended by modification beyond the maximum duration specified in this rule.
(C) The director may issue any permit for a duration that is less than the full allowable term under this rule.
(1) Permits to drill for class I and class V wells shall terminate within eighteen months of the effective date of the permit to drill if the owner or operator has not undertaken a continuing program of installation or modification or has not entered into a binding contractual obligation to undertake and complete within a reasonable time a continuing program of installation or modification.
(2) The director may modify a permit to drill to extend these dates of expiration by up to twelve months if the applicant submits, within a reasonable time before the termination date, an application for modification containing information that, in the judgment of the director, adequately justifies an extension of time.
