Springs BMAPs Basin Management Action Plan (BMAP) Program Division - PowerPoint PPT Presentation

Springs BMAPs Basin Management Action Plan (BMAP) Program Division of Environmental Assessment & Restoration

Overview • Background • New requirements • Examples • Discussion 2

Water Quality Restoration • Watershed Restoration Act (403.067 Florida Statute) • Enacted in 1999, amended in 2006 for Basin Management Action Plans (BMAPs) • Updates in 2016 3

Florida Springs andAquifer ProtectionAct • New in 2016 • Florida Springs and AquiferProtection Act – Sub-Sections 373.801– 373.813, F.S. – Outstanding Florida Springs 4

Springs andAquifer ProtectionAct (cont.) All new or revised BMAPs must include: • Priority ranking of all projects needed to meet TMDL • Planning-level estimates for all projects – Costs – Completion dates – Expected load reduction • Source and amount of financial assistance And since springs are special… 7

Springs andAquifer ProtectionAct (cont.) Delineate springshed • Delineate a Priority Focus Area (PFAs) for each • spring Identification of point sources and nonpoint • source categories with estimated load allocations OSTDS remediation plan where needed • Achieve TMDL in 20 years! • 8

Springs andAquifer ProtectionAct (cont.) • Specifically requires: – Fertilizer ordinance for all local governments – Agricultural Best Management (BMPs) • Nitrogen Source Inventory Loading Tool (NSILT) – Provides relative contribution of nonpoint and point source contributions of loading to ground water • Delineates within the priority focus area (PFA): – List of projects – Create an OSTDS Remediation Plan if OSTDS loads are greater than or equal to 20% of nitrogen load, or determined to be needed by DEP • Prohibits within a PFA: – Wastewater treatment facilities greater than 100,000 gallons per day (GPD), UNLESS advanced wastewater treatment (AWT) is used – New OSTDS on less than one-acre lots, if in conflict with a OSTDS remediation plan – Ban on land application of biosolids – Hazardous waste facilities 9

BMAP Inputs • Priority Focus Area (PFA) • Nitrogen Source Inventory Loading Tool (NSILT) – Estimate N loading to groundwater within BMAP areas and identify potential sources – Dependent on recharge rates – Identify sources for which reductions in N loading could achieve restoration of impaired waters • Customize for individual spring basins 10

PFA Example • PFA is just that – focus area • Restoration activities needed throughout basin • Certain provisions will apply in entire BMAP area 11

NSILT Example – Wakulla Springs • Nitrogen loading estimates to ground water include these considerations: – Attenuation factor for each of the source categories – Rate of ground water recharge within the aquifer Example figure displays • relative nitrogen loads to ground water contributed from evaluated source categories 12

Silver and Rainbow Springs • TMDLs adopted for: – Silver Springs – Silver Springs Group – Upper Silver River – Rainbow Springs Group – Rainbow Spring Group Run • BMAP adopted Oct 2015 (Silver) and Dec 2015 (Rainbow) • Joint OSTDS advisory committee • OSTDS remediation plan – Required by statute no later than end of June 2018 13

Springs Coast BMAPs adopted: • Rainbow Springs BMAPs in development: • Crystal River / Kings Bay • Weeki Wachee Total maximum daily loads (TMDLs) adopted: • Homosassa • Chassahowitzka • Aripeka 16

OSTDS Remediation Plan OSTDS Remediation Plan to help achieve TMDL • reduction forthese sources within 20 years Parts of the Plan • Scientific Information – Effects of nutrients on springs • Public Education plan – OSTDS Information • Nutrient Reducing Projects – Cost-effective and • financially feasible 18

OSTDS #’s 19

OSTDS Remediation Plan Objectives • Evaluate and collect scientific information • Develop education plan • Identify and develop projects to reduce loading Plan • Prioritize areas where greatest risk exists • Determine areas of opportunity (cost/benefit ratio) 20

How to Achieve the TMDL? • BMAP area • PFA for Outstanding Florida Springs • BMAP area load reductions based on NSILT estimates • 5-, 10-, and 15-year milestones • OSTDS Remediation Plan • Projects to meet 5-, 10-, and 15- year milestones by source category adequate to meet TMDL in 20 yrs • Monitoring plan 21
