7 Water Quality Impairment Identified TMDLs In 2004 FDEP listed three Class I waters in the Shell & Prairie Creek Watersheds as verified impaired: WBID #2040 Myrtle Slough (Shell Creek) Chloride, sp. conductance, TDS WBID #2041 Shell Creek Chloride, sp. conductance, TDS WBID #1962 Prairie Creek Sp. conductance, TDS

11 Drought Conditions

12 Land Use in Watersheds Agriculture dominates 53% of area is agricultural land use 179 water use permits in Shell & Prairie Creek Watersheds 89% are agricultural 62.6 mgd permitted Majority are citrus agriculture

13 Location of SPJC Watersheds

15 Response to Impairment Stakeholders group formed 2001: Florida Department of Environmental Protection Florida Department of Agriculture and Consumer Services Southwest Florida Water Management District South Florida Water Management District University of Florida Institute of Food and Agricultural Science USDA/NRCS Charlotte Harbor National Estuary Program City of Punta Gorda Charlotte County Desoto County Peace River Valley Citrus Growers Association Florida Farm Bureau Florida Citrus Mutual Desoto/Charlotte Farm Bureau Florida Fruit and Vegetable Association Charlotte Harbor Environmental Center East Charlotte Drainage District Joshua Water Control District Private Agricultural Interests

16 Response to Impairment Stakeholders develop a Reasonable Assurance Plan documenting management actions that will restore water bodies to unimpaired conditions TMDLs will not be developed RA Plan will be responsible for improving water quality Goal of Reasonable Assurance Plan Improve water quality to meet Class I Standards TDS < 500 mg/l Chloride < 250 mg/l Goal will be reached by 2014 Goal will be achieved through implemented management actions Frequent reporting on performance monitoring results

17 Management Actions SPJC Well Back Plugging Program Facilitating Agricultural Resource Management Systems (FARMS) Program SWFWMD Resource Regulation Quality of Water Improvement Program (QWIP) Environmental Quality Incentives Program (EQIP) Florida Dept. of Agriculture & Consumer Services (FDACS) - Best Management Practices (BMPs) Land Acquisition SWUCA Recovery Strategy/Regional Water Management Plan Research and Education/Outreach

18 SPJC Well Back-Plugging Funding assistance initiated Designed to back-plug wells to improve water quality Over $400,000 currently budgeted (maximum reimbursement of $6,500/well) 1000 us/cm goal for each well To date 40 wells have been back-plugged Avg. reduction in Cl = 68% Avg. reduction in TDS = 55% Avg. yield loss = 24%

21 FARMS Program Overview FARMS is a BMP cost-share reimbursement program for agricultural projects located in the SWUCA Reduce Floridan Aquifer ground water withdrawals Improve water quality Conserve, restore, or augment water resources and ecology Provides up to 75% reimbursement for project costs Total funding over $6M

22 What does FARMS Fund? Precision Irrigation Soil Moisture Meters Auto Pump Starts/Valves

23 Alternative Supplies Surface water Tail water recovery Requires agricultural reservoirs

24 FARMS Program Status Two priority areas in the SWUCA Upper Myakka Watershed (Manasota) Shell, Prairie, and Joshua Creek Watersheds (Peace) 37 Board approved projects 11.2 mgd predicted ground water offset 19 Complete and operational projects Possible District-wide expansion in FY2008

25

26 Resource Regulation Well Construction Permitting Permit stipulations in SPJC area on new wells Provide maximum TD limits Require water quality sampling with depth Establish a maximum sp. conductance limit of 1,000 us/cm on well discharge

27 Resource Regulation Water Use Permitting Special conditions on new/renewed permits in SPJC area Well sampling Participation in Well Back-Plug Program or FARMS 78% of existing permits in SPJC will be reviewed/renewed by 2014

28 Quality of Water Improvement Program (QWIP) Established in 1974 to improve impacted water quality due to improper well construction or abandoned flowing wells 47 wells plugged (total plug) in Shell and Prairie Creek watersheds Long-term program with funding level of approximately $650,000 annually

29 Status of RA Plan Approval In March 2005, FDEP provided a letter to the District indicating their approval of the RA Plan The EPA provided a letter indicating support of the RA Plan - pending final review of the Group 3 verified impaired waters list The Group 3 list is under further revision The RA Plan will be first in the nation to be approved by the EPA
