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

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…

Springs andAquifer ProtectionAct (cont.)

7

• 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!

Springs andAquifer ProtectionAct (cont.)

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

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

• f 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

• 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

NSILT Example – Wakulla Springs

12

• 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

BMAPs in development:

• Crystal River / Kings Bay
• Weeki Wachee

Total maximum daily loads (TMDLs) adopted:

• Homosassa
• Chassahowitzka
• Aripeka

Springs Coast

• 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

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
• pportunity

(cost/benefit ratio)

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
