2 TMDL PRIORITIZATION REPORT MS4 Permit No. FLS Submitted to Florida Department of Environmental Protection (DEP): January 31, 2012 Considered only DEP-adopted, EPA-established TMDL s Factors based on practicality and relevance Included streams/canals and lakes Included both nutrient and bacteria TMDL s

3 Six (6) Factors used to help select waterbody 1. Shareholder Collaboration Potential 2. Shared Control 3. Impairment Status 4. Pollutant Loading 5. Landlocked Basin 6. Percent in City Limits Each factor worth maximum 3 points Prioritization Plan Waterbody selected will be highest in points (max =18 points)

4 6 Factors used to help select waterbody 1. Shareholder Collaboration Potential Waterbody entirely in City limits or shared jurisdiction More entities involved, potentially more difficult to accomplish goal on same time frame CRITERIA: Low number of stakeholders = 3 points Medium number of stakeholders = 2 points High number of stakeholders = 1 point

5 6 Factors used to help select waterbody 1. Shareholder Collaboration Potential 2. Shared Control Weighted emphasis CRITERIA: City only = 3 points Multiple stakeholders = 0 points

6 6 Factors used to help select waterbody 1. Shareholder Collaboration Potential 2. Shared Control 3. Impairment Status Degree of pollution/ reductions needed Averaged percentages of pollutant reductions CRITERIA: Over 75% = 3 points Between 50-74% = 2 points Between 25 49% = 1 point Less than 25% = 0 points

7 6 Factors used to help select waterbody 1. Shareholder Collaboration Potential 2. Shared Control 3. Impairment Status 4. Pollutant Loading Land uses in basin Used Orange Co Property Appraisers DOR Use Codes Integrated into GIS map with basin delineation to determine percentage of major land uses DEP WBID info & Orange County zoning used for determining land uses outside of City limits

8 6 Factors used to help select waterbody 1. Shareholder Collaboration Potential 2. Shared Control 3. Impairment Status 4. Pollutant Loading (continued) Some land uses excluded since limited nutrient impact Industrial areas contribute more pollution than others Increased number of outfalls contribute more pollution Residential areas contribute more bacterial pollution Considered when evaluating Bacteria TMDL s

9 6 Factors used to help select waterbody 1. Shareholder Collaboration Potential 2. Shared Control 3. Impairment Status 4. Pollutant Loading CRITERIA: High = 3 points Medium = 2 points Low = 1 point

10 6 Factors used to help select waterbody 1. Shareholder Collaboration Potential 2. Shared Control 3. Impairment Status 4. Pollutant Loading 5. Landlocked Basin Basins connected to other basins given priority Basins contributing pollutants outside of City limits given higher priority CRITERIA: Landlocked = 3 points Not landlocked = 0 points

11 6 Factors used to help select waterbody 1. Shareholder Collaboration Potential 2. Shared Control 3. Impairment Status 4. Pollutant Loading 5. Landlocked Basin 6. Percent in City Limits Pollutant(s) origin CRITERIA: 100% basin acreage within City limits = 3 points Over 75% basin acreage within City limits = 2 points Over 50% basin acreage within City limits = 1 point

12 Part VIII - B. Impaired Waters with DEP-Adopted, EPA-Established TMDLs 3. For water bodies with an adopted DEP TMDL or an EPA-established TMDL but without a BMAP Bay Lake (WBID 3004G) TN & TP Lake Lawne (WBID 3004C) TN & TP Lake Silver (WBID 3004O) TN & TP Little Wekiva Canal (WBID 3004) TN & BOD Little Wekiva Canal (WBID 3004) Fecal coliform Little Econlockhatchee River (WBID 3001) Fecal coliform

Shareholder Collaboration Potential CRITERIA: Low number of stakeholders = 3 points Medium number of stakeholders = 2 points High number of stakeholders = 1 point Bay Lawne Silver Little Wekiva Canal Little Econ River Shared Collaboration (Actual Value) Shared Collaboration (Points Assigned) Multiple Multiple

14 2. Shared Control CRITERIA: City only = 3 points Multiple stakeholders = 0 points Bay Lawne Silver Little Wekiva Canal Little Econ River Shared Control (Actual Value) Multiple Multiple Shared Control (Points Assigned)

15 3. Impairment Status Degree of pollution/ reductions needed Averaged percentages of pollutant reductions CRITERIA: Over 75% = 3 points Between 50-74% = 2 points Between 25 49% = 1 point Less than 25% = 0 points Bay Lawne Silver Little Wekiva Canal Little Econ River Impairment Status (Avg Reduction Needed) Impairment Status (Points Assigned) 52.5% 37.5% 47% 28.1% Nutr & 42.6% FC 57%

16 4. Pollutant Loading CRITERIA: High = 3 points Medium = 2 points Low = 1 point Bay Lawne Silver Little Wekiva Canal Little Econ River Pollutant Load (Predom Land Use [Actual Value]) A = 80ac R = 16% C = 14% I = 70% Outfl = 2 A =1,030ac R = 22% C = 30% I = 48% Outfl =8 A = 347ac R = 82% C = 18% I = 0% Outfl = 10 Residential Outfl = 1 Residential Outfl = 5 Pollutant Load (Points Assigned)

17 5. Landlocked Basin Basins connected to other basins given priority Basins contributing pollutants outside of City limits given higher priority CRITERIA: Landlocked = 3 points Not landlocked = 0 points Locklocked (Actual Value) Landlocked (Points Assigned) Bay Lawne Silver Little Wekiva Canal Little Econ River

18 6. Percent in City Limits Pollutant(s) origin CRITERIA: 100% within City limits = 3 points Over 75% within City limits = 2 points Over 50% within City limits = 1 point Bay Lawne Silver Little Wekiva Canal Little Econ River In City Limits (Actual Value) In City Limits (Points Assigned) 36% 66% 100% 37% 16%
