  5. (a) The permit may specify expiration dates by which the construction must be started and completed, which dates shall be compatible with any federal or state, or both, grants or grant funds impacted. The commissioner may grant an extension of time for start and completion of construction if the commissioner believes the extension is necessary and justified.
