Program for Phase I Large & Medium MS4s - Who's Covered

 

All Phase I large and medium MS4s were previously designated by EPA, based on the total population within the geo-political boundaries of the municipalities.

• A large MS4 is any MS4 that is located in an incorporated place or county with a population of 250,000 or greater.
   
• A medium MS4 is any MS4 that is located in an incorporated place or county with a population between 100,000 and 249,999.

Other MS4s located in areas with populations below 100,000 were also designated into the program as Phase I MS4s by EPA.  The list of Permitted Phase I MS4s in Florida is organized by permit title and provides contact information for each regulated entity.  DEP assumed responsibility for all Phase I MS4 permits when it became the permitting authority in October 2000.
