The delegation of authority must be consistent with s. 373.441 and chapter 62-344, Florida Administrative Code. To further streamline permitting within the Miami-Dade County Lake Belt, the department and Miami-Dade County are encouraged to work with the United States Army Corps of Engineers to establish a general permit under s. 404 of the Clean Water Act for limerock mining activities within the geographic area of the Miami-Dade County Lake Belt consistent with the report submitted in February 1997. Miami-Dade County is further encouraged to seek delegation from the United States Army Corps of Engineers for the implementation of any such general permit.
