Set TMDLs for Lake Okeechobee Tributaries - FDEP

Speed up development of total maximum daily loads of phosphorus allowed for the Lake Okeechobee watershed tributaries to protect and restore downstream water bodies

TMDLs = Total Maximum Daily Loads

18

Mandatory Fertilizer BMPs - FDACS

Revised application rates for agriculture; low phosphorus for urban use

Reassess fertilizer application rates for agriculture and encourage the development and use of low phosphorus fertilizer in urban settings

Mandatory Fertilizer Best Management Practices (BMPs):

19

Innovative Land-Use Planning - FDCA

Innovative land-use planning techniques, including use of Florida’s Rural Land Stewardship Areas Program, to facilitate the acquisition of lands for public works

Growth Management to Encourage Innovative Land-Use Planning

20

Eliminate Land Applications of Residuals - FDEP

End the practice of depositing domestic wastewater residuals on land, which can result in excess nutrients getting in tributaries and estuaries

Residuals Contain Nutrients that are land applied in Phosphorus-Sensitive Basins
