The District allows certain minor modifications of Environmental Resource Permits (ERPs) to be made without completing a full ERP application form and without payment of an application fee. Rule 40D-4.331, F.A.C., is amended to require use of a new Modification Short Form instead of a letter to request these minor modifications, to allow applications to extend the duration of an ERP to be made using the Modification Short Form, and to clarify that permits may be extended in duration, as opposed to being “renewed.” Applications to extend the duration of an ERP will be granted if the construction proposed to take place during the extended permit duration will comply with the District’s rules in effect at the time the application is filed.
