The commissioner may waive the permit requirement for development in the coastal area pursuant to P.L. 1973, c.185 (C.13:19-1 et seq.) for any development that involves the grading or excavation of a dune by a governmental agency if the commissioner finds that such a waiver is warranted as a result of a storm, natural disaster or similar act of God.
