1 Springs Coast Basin Management Action Plans (BMAPs) January 2018 Terry Hansen P.G., Basin Coordinator

2 Springs Coast BMAP Study Areas and Priority Focus Areas (PFAs)

3 Florida Springs and Aquifer Protection Act (2016-1) The 2016 Florida Springs and Aquifer Protection Act lists requirements for BMAPs for Outstanding Florida Springs (OFS): BMAPs adopted within two years after initiation five-year incremental milestones implementation plan designed achieve the TMDL no more than 20 years after adoption ( (1)(b), F.S.).

4 Florida Springs and Aquifer Protection Act (2016-1) Specifically requires: Identification of point sources and nonpoint source categories with estimated load allocations (NSILT). Fertilizer ordinance for all local governments. Agricultural BMPs. Priority Focus Area (PFA): Definition: Area or areas of a basin where the Floridan Aquifer is generally most vulnerable to pollutant inputs where there is a known connectivity between ground water pathways and an Outstanding Florida Spring (OFS). Prohibitions within a PFA Must be adopted within BMAP Creation of an on-site sewage treatment and disposal system (OSTDS) Remediation Plan if OSTDS loads are greater than or equal to 20% of nitrogen load, or determined to be needed by the DEP.

13 TMDLs / BMAP To achieve the TMDLs, BMAP implementation will be a 20-year process Plan will define nitrogen reduction milestones: 30% reduction within 5 years 50% reduction within 10 years 20% reduction within 15 years Use last 5 years to finish up and see results

14 KB/CR Gap Analysis Nitrogen Source Credits Based on Project Tables (lb- N/yr) OSTDS 103,868 Urban Turf Fertilizer 4,050 Atmospheric Deposition Farm Fertilizer (FF) 10,604 Sports Turf Fertilizer (STF) 4,886 Livestock 3,079 Description Credits identified for stakeholder OSTDS projects (enhancement or sewer) DEP approved credits (up to 6 %) for public education activities as well as credits identified for stakeholder stormwater projects No reduction 15 % BMP credit on FF load to groundwater, assuming 100 % owner-implemented BMPs on all fertilized lands 6 % BMP credit for sports fields and 10 % BMP credit for golf courses on STF load to groundwater, assuming 100 % BMP implementation on golf courses and sports fields 10 % BMP credit on load to groundwater, assuming 100 % owner-implemented BMPs at all livestock facilities Wastewater Treatment Facility 9,322 Achieved by BMAP WWTF policy (achieving 3 or 6 mg/l) Total Credits 135,810 Required Reduction 274,000 Load Remaining: 138,190

16 WW BMAP Gap Analysis Nitrogen Source Credits Based on Project Tables (lb-n/yr) Description OSTDS 27,538 Credits identified for stakeholder OSTDS projects (enhancement or sewer) Urban Turf Fertilizer 5,230 DEP approved credits (up to 6%) for public education activities as well as credits identified for stakeholder stormwater projects Atmospheric Deposition No reduction Farm Fertilizer (FF) 24,590 Sports Turf Fertilizer (STF) 5,342 Livestock 9,135 15% BMP credit on FF load to groundwater, assuming 100% ownerimplemented BMPs on all fertilized lands 6% BMP credit for sports fields and 10% BMP credit for golf courses on STF load to groundwater, assuming 100% BMP implementation on golf courses and sports fields 10% BMP credit on load to groundwater, assuming 100% owner-implemented BMPs at all livestock facilities Wastewater Treatment Facility (WWTF) 33,058 Achieved by BMAP WWTF policy (achieving 3 or 6 mg/l) Total Credits 158,164 (Includes 53,272 lb-n/yr from Pasco County Restoration Project FY17/18) Required Reduction 195,200 Load Remaining: 37,036

17 GAP Reduction - (OSTDS) Remediation Plan The Florida Springs and Aquifer Protection Act mandates that a BMAP with OSTDS contributing at least 20 % of nonpoint source load within a PFA include an OSTDS Remediation Plan. OFS Springs in BMAPs with <20% OSTDS also include a Remediation Plan. The OSTDS Remediation Plan includes: Public education plan Scientific information on effect of nutrients on springs Projects designed to reduce nutrient impacts from OSTDS The OSTDS Remediation Plan is included as an appendix in the BMAP

18 OSTDS Options The Springs Coast BMAPs basically requires OSTDS systems to have a minimum nitrogen-reducing efficiency of 65%. In Florida, the following systems have been approved and have more than 65% of nitrogen-reducing efficiency (plus the drainfield attention). 1. Aerobic Treatment Units (ATU) technologies that meet the NSF 245 standard. 2. A set of performance based treatment systems (PBTS) and media filter systems that are being tested by FDOH through the innovative system testing processes Passive nitrogen-reducing in-tank systems tested through the Florida Onsite Sewage Passive Nitrogen Reduction Strategies Study. 4. Sewering From DOH 19DEC17

19 OSTDS Remediation Plan In the PFA and on lots of all sizes, all property owners must, no later than 20 years after BMAP adoption, abandon the OSTDS, install a new OSTDS, or retrofit an existing OSTDS to include nitrogenreducing enhancement features as specified in in Section D.3.1. In order to be successful, local funding needs to be available to homeowners
