A Florida Keys National Marine Sanctuary (FKNMS) permit is required for projects that would otherwise not be allowed because they are prohibited by sanctuary regulations. FKNMS also has the ability to issue a letter of authorization for a permit issued by any federal, state, or local authority with jurisdiction over a project. FKNMS requires the same completed forms, drawings, and other pertinent documents required by Army Corps of Engineers, Florida Department of Environmental Protection (DEP), and South Florida Water Management District (SFWMD) in order to review projects and determine if impacts to sanctuary resources will occur. The dredging or removal of canal plugs is prohibited by one or more FKNMS regulations.
