Total Maximum Daily Loads
Water quality targets needed to
return a waterbody to a healthy state
Provides:
•Quantitative restoration targets
•Identification of pollutant sources
•Regulatory “backstop”
•Application of good science to management
Basin Management Action Plans
(BMAPs) implement TMDLs

BMAP Basics
• Developed by stakeholders; guidance from DEP
• Adopted by DEP Secretarial Order
• Linked directly to municipal stormwater and GRU
wastewater permits
• Linked to best management practices and
education for nonpoint sources (e.g. agriculture)
• Evaluated annually; revised every five years

Key Parts of the BMAP Document
•Refined source identification
•Management actions (projects)
•Focused studies (good science)
•Funding
•Monitoring & project tracking
•Commitments
•Follow-up and plan revision
BMAP Development
• Improved scientific understanding (nutrients
and bacteria)
• Developed new projects to address TMDLs,
including cooperative efforts
• Expanded the scope of existing projects
• Began implementing projects to address
known issues
• Identified additional studies to refine source
understanding
Working With Uncertainty
• Many unknowns remain in this watershed (e.g.
lake nutrient sources)
• Thus, the Orange Creek BMAP does not lay out all
necessary actions to achieve TMDLs
• Significant restoration efforts are underway to
address known sources
• Additional projects will be implemented as the
scientific understanding matures
Application of Good Science
Wise Use of Resources
BMAP Projects
The BMAP contains over 100 activities that
address bacteria and nutrient sources
•
•
•
•
Stormwater retrofits
Wastewater infrastructure management
Pollution prevention
Agricultural and municipal BMP
implementation
• Land use planning and land development
• Public education
Bacteria “Hot Spot” Project
• Extensive water quality sampling and microbial
source tracking (GRU & Alachua County)
completed to identify hot spots
• “Hot Spots” addressed geographically
• Pilot = Elizabeth Creek
GRU = sewer
G’ville = stormwater
ACHD = septic tanks
ACEPD = monitoring
DEP = Data collection & evaluation
Paynes Prairie/Sweetwater
Branch Sheetflow Restoration
Feasibility study completed
• Constructed water quality treatment area
• Rehydrate existing wetlands
• Remove direct discharge to Floridan aquifer
• Will help meet TN reductions identified in TMDL
Steps needed for project to proceed
• Funding commitments
• Land acquisition
• Project design
Studies Underway and
Planned
BMAP identifies specific studies and
monitoring needed to guide management
•

Microbial source tracking
In-stream bioassessments
Storm event nutrient assessments
Stormwater inlet protection pilot project
Reclaimed water master plan
BMAP Implementation Cost
Approx. $200M in projects completed or in
progress for the Orange Creek BMAP area
Detailed Studies
$14M in broader
actions/ programs
emphasized in BMAP
areas
Costs not estimated for
most future projects

Commitment to Plan
Implementation
Once adopted by DEP, the BMAP is legally binding for
responsible parties through Watershed Restoration
Act and stormwater permit program
Local commitments are needed before DEP will adopt
the BMAP
Government and non-government Working Group
members signing statements of commitment
Recommended Action
Adopt Resolution 07-xxx
A RESOLUTION OF THE BOARD OF
COUNTY COMMISSIONERS OF
ALACHUA COUNTY, FLORIDA, TO
SUPPORT AND WORK ON THE
IMPLEMENTATION OF THE ORANGE
CREEK BASIN MANAGEMENT ACTION
