PHOSPHORUS LOAD REDUCTION MEASURES ON EXISTING AND FORMER DAIRY PROPERTIES IN THE LAKE OKEECHOBEE WATERSHED
James A. Laing South Florida Water Management District West Palm Beach, FL
The objective of the Dairy Best Available Technologies (BATs) Program was to identify, select, monitor and oversee implementation of BATs that would significantly reduce the export of phosphorus (P) from dairy operations into tributaries and Lake Okeechobee. Various alternatives were evaluated to determine the best comprehensive system of technologies to address the multiple dairy farm components (High Intensity Areas, waste management system, pastures, etc.). The goal of the program was achieved using an objective methodology that allowed for review and input by a multi-agency team (Florida Department of Environmental Protection, Florida Department of Agriculture and Consumer Services, United States Department of Agriculture – Natural Resource Conservation Service, University of Florida – Institute of Food and Agricultural Sciences, and the South Florida Water Management District) and stakeholders throughout the technology selection and implementation process. Implementation of the selected technology, edge of farm stormwater retention/detention and reuse followed by alum chemical treatment, has occurred at four distinct project sites in the Lake Okeechobee watershed. Monitoring and evaluation has been underway for three years and will be presented in detail. The objective of another initiative on former dairy sites was to implement one or more alternatives to minimize P discharges from the Lamb Island Dairy Remediation Project site. The implemented alternatives were chosen to minimize P discharges to the maximum extent practicable while taking into consideration cost effectiveness as well as the minimization of long term operation and maintenance requirements. The design and implementation of this project also received review and input from a multi-agency team. Monitoring and evaluation of this project site will also be presented in detail.
