Department Recommendations

DOH Recommendations 1

* Set a discharge limit of 10 milligrams per liter of
total nitrogen for new systems, systems being
modified, and for existing systems in the primary
and secondary Wekiva Study Area protection
zones.
* Prohibit the land-spreading of septage and
grease trap waste in the Wekiva Study Area.
Septage waste would be required to be
disposed of at wastewater treatment plants.

DOH Recommendations 2

* Evaluate the economic feasibility of sewering versus
nutrient removal upgrades to existing onsite sewage
treatment and disposal systems. A phased-in approach
to replacing the remaining existing systems should be
developed with a target completion date of 2010.

* Establish new regional wastewater management entities
or modify existing ones to oversee the maintenance of all
wastewater discharged from onsite sewage treatment
and disposal systems in the study area. These
programs should take the privatization approach and
contract with existing licensed septic tank contractors.

The

Recommended System

A Nutrient Reducing System with Drip Irrigation

System Construction and

Operating Costs

* Conventional system
$5,500 to $7,000

No operating permit
except IM zoned areas

* Proposed system
$7,500 to $9,000

$100 operating permit
Every 2 years

$140 in annual
electric costs

Maintenance agreement

DOH Rule Adoption Process

Rule Adoption

* Primary issues are to adopt a nitrogen limit and
require drip irrigation for onsite systems
* Permitting process is already in place in the rule

* Public Input Technical Review and Advisory
Panel (TRAP) established by 318.0068 FS
* Formal TRAP Meeting to review proposals in
May, 2005;
* Anticipated rule implementation as early as
March 2006

Solving Water Pollution Problems
in the Wakulla Springshed

The City of Tallahassee's Efforts to
Reduce Stormwater Pollution

Hydrogeology Workshop
May 12-13, 2005

Water Quality and Stormwater Pollution

* City of Tallahassee shares the goal of
preserving water quality with Leon and
Wakulla Counties, FDEP, EPA, Friends of
Wakulla Springs and all Stakeholders.

* Best accomplished through technically
sound planning and goal setting.

The Reality of Our Working Environment

* There are many competing needs for a
community's financial resources; fire, police,
schools, roads.....
Managing and improving water quality is an
expensive endeavor.
Due diligence must be used to ensure that the
limited funding that is available, is effectively
applied.
Failure to do so, actually works against the goal of
preserving water quality.

S* Pollutant Loading

\ /with BMP data to
develop a Program
S- Cost Model.
-* Done by evaluating
actual pond sites and
developing cost
estimates and removal
rates.
I-- Yielded cost curves for
-- a variety of alternative
S/ program levels.

Target Watersheds Alternative

Revenue limitations
led to examination of
alternative
approaches.

Identified 20 Target
-~ Watersheds with
)n highest loadings.

Target Watersheds Alternative

* $60 million in investment over approx. 20 years

* Not a "end-all" solution but a realistic start for
what will be a long term effort.

* Even this approach presents challenges.

o Stormwater perspectives: urban vs. national forest vs.

o TMDLs underway (assimilation capacity of water bodies
to minimize water qual. and quant. impacts
o First address stormwater entering most vulnerable
areas
o Continue working with DOT re: stormwater and
