(a) Renewal. At the expiration of each permit, it may be renewed under the same procedure herein specified for an original application.

(b) Nonuse of permit. Nonuse of a permit for a period of three years following the date of issuance shall constitute an abandonment of the development or subdivision and the permit shall be considered expired. For purposes of this section, for a permit to be considered "used," construction must have commenced and substantial progress toward completion must have occurred within the three-year period, unless construction is delayed by litigation or proceedings to secure other permits or to secure title through foreclosure, or unless, at the time the permit is issued or in a subsequent proceeding, the District Commission provides that substantial construction may be commenced more than three years from the date the permit is issued.

(c) Extensions. If the application is made for an extension prior to expiration, the District Commission may grant an extension and may waive the necessity of a hearing.

(d) Completion dates for developments and subdivisions. Permits shall include dates by which there shall be full or phased completion. The Natural Resources Board, by rule, shall establish requirements for review of those portions of developments and subdivisions that fail to meet their completion dates, giving due consideration to fairness to the parties involved, competing land use demands, and cumulative impacts on the resources involved. If completion has been delayed by litigation, proceedings to secure other permits, proceedings to secure title through foreclosure, or because of market conditions, the District Commission shall provide that the completion dates be extended for a reasonable period of time.
