EXECUTIVE SUMMARY
Recommendation to approve time and material Work Order to PBS&J under Contract 09-
5262-CZ to develop locally-relevant and site-specific alternative water quality criteria for
the Clam Bay estuary and provide continued technical support for the next 6 months to the
Clam Bay technical work team as outlined in the attached PBS&J proposal dated March 7,
2011 not to exceed $77,148.
OBJECTIVE: To approve Work Order with PBS&J under Contract 09-5262-CZ to
develop locally-relevant and site-specific alternative water quality criteria for the Clam
Bay estuary and provide continued technical support for the next 6 months to the Clam
Bay technical work team.
CONSIDERATIONS:
The State of Florida,. through the Florida Department of Environmental Protection
(FDEP) has historically used a narrative standard for nutrient concentrations in surface
waters, which states that nutrient concentrations must not cause "...an imbalance of
flora and fauna." This approach has generally served the State well, as it allows for the
recognition that there can be locations where water quality impairment from a regulatory
viewpoint can actually reflect natural conditions. However, in January of 2009, the
Assistant Administrator of EPA concluded that the State of Florida's narrative standard
for nutrients was inadequate, and that EPA would then "... propose numeric nutrient
criteria for lakes and flowing waters within 12 months, and for estuaries and coastal
waters, within 24 months."
On November 14, 2010, EPA Administrator Lisa Jackson finalized the Water Quality
Standards for the State of Florida's Lakes and Flowing Waters. Included in that rule
was the comment that, "These final standards set numeric limits, or criteria, on the
amount of nutrient pollution allowed in Florida's lakes, rivers, streams and springs."
This rule, which covers lakes, rivers and springs, will take effect on March 6, 2012.
Additionally, EPA has stated that it will release revised numeric nutrient criteria for
estuaries, their watersheds, and coastal waters by November 2011, with final nutrient
criteria developed by August 2012.
This item is focused on developing numeric water quality criteria for Clam Bay, to be
submitted for consideration by FDEP and the EPA as a locally-developed and
appropriate set of water quality criteria for the protection of Clam Bay. This SOW is
predicated upon the following issues, relevant to Clam Bay:
1) Portions of Clam Bay consistently fail various water quality standards, as outlined
in FDEP's Impaired Waters Rule;
2) However, it is likely that for Clam Bay the water quality standards themselves are
problematic;
3) Within Clam Bay, there is little evidence of adverse impacts to water quality from
nutrient availability;
4) Clam Bay could be appropriately considered a location where a "hold the line"
approach to nutrient availability is appropriate, and

.
.
4/26/2011 Item 10.G.
5) Alternative criteria for nutrients, chlorophyll-a and dissolved oxygen are thus
appropriate for Clam Bay.
Water quality data from ongoing monitoring efforts of Collier County will be compiled,
reviewed for consistency with FDEP guidelines for the development of numeric criteria,
and then analyzed for the development of regulatory water quality criteria.
The following water quality data will be analyzed for this effort:
· Water temperature (degrees Celsius)
· Salinity andlor specific conductance (psu or IJmhos / cm)
· Dissolved oxygen (mg / liter)
· Inorganic nitrogen species (mg /liter)
. Total nitrogen (mg / liter)
· Inorganic phosphorus (mg / liter)
· Total phosphorus (mg / liter)
· Chlorophyll-a (lJg /liter)
· Turbidity (NTU)
· Color (PCU)
· Secchi disk depths (meters)
· Fecal coliform bacteria (# /100 ml)
In addition, the Clam Bay system water quality data set will be compared and
contrasted to similar data sets from nearby "reference" estuaries identified by other
researchers. Comparisons will be made between the nutrient and eutrophication
indicators relationships in Clam Bay vs. nutrient and eutrophication indicators in these
commonly-cited reference estuaries. Fecal coliform bacteria in Clam Bay will be
sampled and analyzed on a pass through basis to determine the genera of bacteria
more specific to humans and/or wildlife sources.
A Final Report that formalizes the rationale behind the development of locally-derived
alternative criteria for dissolved oxygen, nutrients and chlorophyll-a for Clam Bay, as
well as a documentation of the likely source(s) of fecal coliform bacteria within Clam
Bay. This report will then be presented for FDEP for proposed agency action to
promulgate site specific criteria for these variables for Clam Bay.
To continue to support Collier County in its efforts to successfully manage Outer, Inner
and Upper Clam Bays, PBS&J will continue to make one staff member available for
attending and participating in the Clam Bay work team dealing with Clam Bay estuary
issues. Support will be available for up to six (6) meetings in CZM offices within Collier
County.
Deliverables associated with this effort will include a final report outlining the data
sources, analytical techniques employed, and derivation of lo~ally-appropriate water
quality criteria for the Clam Bay system. These locally-derived proposed water quality
criteria will include the following:
· Numeric nutrient criteria for nitrogen and phosphorus concentrations within the
Clam Bay system,

Additional Work Request
Contract # 09-5262-CZ
March 7, 2011
CLAM P ASS/BAY ESTUARY
PBS&J is pleased to provide a scope of work for the development of numeric nutrient criteria
for Clam Bay. The intention of this Work Assignment is to develop numeric criteria for nutrient
and chlorophylI-a concentrations for the waters of Upper, Inner and Outer Clam Bays, as well
as downstream protective values (DPY) for nitrogen and phosphorous, and to oversee source
identification efforts for fecal coliform bacteria for Upper, Inner and Outer Clam Bays. In
accordance with Collier County Contract Number 09-5262-CZ "County Wide Engineering
Services-Coastal Zone" the following scope of work is presented herein.
SCOPE OF WORK
Task 1 - Data Compilation. Review and Analvsis
.
Water quality data from ongoing monitoring efforts of Collier County will be compiled,
reviewed for consistency with FDEP guidelines for the development of numeric criteria, and
then analyzed for the development of regulatory water quality criteria.
The following water quality data will be analyzed for this effort:
· Water temperature (degrees Celsius)
· Salinity and/or specific conductance (psu or Ilmhos 1 cm)
. Dissolved oxygen (mg 1 liter)
. Inorganic nitrogen species (mg 1 liter)
. Total nitrogen (mg 1 liter)
. Inorganic phosphorus (mg 1 liter)
. Total phosphorus (mg 1 liter)
· ChlorophylI-a (Ilg 1 liter)
· Turbidity (NTU)
· Color (pCU)
. Secchi disk depths (meters)
. Fecal colifornl bacteria (# 1100 ml)
These data will be analyzed to detect the presence of potential eutrophication-related empirical
relationships, such as positive correlations between total nutrients and Chlorophyll-a, negative
correlations between inorganic nutrients and Chlorophyll-a, negative correlations between
nutrient concentrations and dissolved oxygen, negative correlations between Chlorophyll-a and
Secchi disk depths, etc.
.
Results will be interpreted to determine if there is clear and unequivocal evidence of an
ongoing and negative impact of nutrient supply on nutrient-related water quality parameters. If
multiple and corroborating lines of evidence of such relationships are found, these would

SCOPE-OF- WORK
indicate the possibility of ongoing nutrient-related impacts to water quality. If no such
evidence is found, or if evidence is inconsistent, then results could indicate the absence of
nutrient-related impacts to water quality.
.
In addition, the Clam Bay system water quality data set will be compared and contrasted to
similar data sets from nearby "reference" estuaries identified by other researchers. For
example, data sets from Fakahathcee Bay and other locations within the Ten Thousand Islands
estuarine complex will be compared and contrasted with the water quality data set from the
Clam Bay system. Comparisons will be made between the nutrient and eutrophication
indicators relationships in Clam Bay vs. nutrient and eutrophication indicators in these
cOlmnonly-cited reference estuaries.
Finally, the Consultant will oversee data collection and interpretation efforts of Source
Molecular Corporation to determine the relative importance of wildlife sources such as birds, as
opposed to human sewage, as a source of fecal coliform bacteria in Clam Bay. As a pass-
through direct expense, samples will be obtained in Upper, Inner and Outer Clam Bay on two
occasions, and assessed for the presence of fecal coliform bacteria, genera of bacteria more
specific to humans and/or wildlife sources, and genetic markers specific to both birds and
humans as sources of fecal coliform bacteria. Results will then be interpreted within the
context of their implications to existing water quality criteria for Clam Bay.
Total Amount of Task 1 = $27,490. $18,040 for fully-loaded labor; $9,450 for direct .
expenses and pass-through for sub-consultants.
Task 2 - Ae-encv Review and Comment
The Consultant will undertake two local peer review efforts. The first effort will involve staff
from Collier County, the City of Naples, the South Florida Water Management District, the
FDEP-Fort Myers office, and faculty from Florida Gulf Coast University. This meeting will be
designed to solicit input on the findings of Task 1 activities. The second local meeting will be
with the County's chosen venue for communication of results to the public, such as a Board of
County Commissioners meeting or other such venues (at the County's discretion).
In addition, the Consultant will participate in two meetings with staff from FDEP- Tallahassee,
with the intent of soliciting input on the process used to develop water quality criteria for the
Clam Bay system. The first presentation will outline the approach used, the data sets analyzed,
and any preliminary findings. Results from this meeting will be used to refine, if needed, the
approaches used to develop local criteria. The second meeting would be a more formal
presentation of the proposed water quality criteria for consideration and eventual adoption by
the FDEP.
Based on the results of efforts within Task 1, and meetings with appropriate regulatory staff
during Task 2, the deliverable for Task 2 will be a Final Report that formalizes the rationale
behind the development of locally-derived alternative criteria for dissolved oxygen, nutrients
and chlorophyll-a for Clam Bay, as well as a documentation of the likely source(s) of fecal

coliform bacteria within Clam Bay. This report will then be presented for FDEP for proposed
agency action to promulgate site specific criteria for these variables for Clam Bay.
Total Amount of Task 2 = $31,784. $29,784 for fully-loaded labor; $2,000 for direct
expenses.
Task 3 - Continued Technical Support and Participation at Local Meetin!!s
To continue to support Collier County in its efforts to successfully manage Outer, Inner and
Upper Clam Bays, the Consultant will continue to make one staff member available for
attending and participating in the Clam Bay work team as Consultant to Collier County, dealing
with Clam Bay estuary issues only. Support will be available for up to six (6) meetings at a
location in or near the City of Naples, and one additional staff member available for up to three
(3) meetings at a location in Collier County. Preparation for, attendance and follow-up
activities will be budgeted based on an estimated total labor effort of 10 hours per staff member'
per meeting. These meetings are expected to cover miscellaneous issues related to the health of
the Clam Bay system, as well as ongoing coordination efforts between the Consultant and
Consultants chosen by the Pelican Bay Foundation. Pelican Bay's consultants are expected to
be working on a coordinated effort to develop proposed potential criteria for levels of dissolved
oxygen within the Clam Bay system.
. Total Amount of Task 3 = $17,874. $16,674 for fully-loaded labor; $1,200 for direct
. expenses.
Deliverables
Deliverables associated with this effort include preparation for and presentations at two local
(Collier County) meetings for peer review and input from various stakeholders, as well as
preparation for and presentations at two meetings with staff from FDEP - Tallahassee.
Deliverables will also include the preparation of draft and final reports outlining the data
sources, analytical techniques employed, and derivation of locally-appropriate water quality
criteria for the Clam Bay system. These locally-derived proposed water quality criteria will
include the following: 1) numeric nutrient criteria for nitrogen and phosphorus concentrations
within the Clam Bay system, 2) numeric criteria for levels of Chlorophyll-a within the Clam
Bay system, 3) numeric nutrient criteria for downstream protective values (DPVs) for
stormwater runoff for the Clam Bay system's watershed, 4) initial source-identification efforts
for fecal colifonn bacteria, and 5) in coordination with ongoing efforts by the Pelican Bay
Foundation and its consultants, proposed criteria for dissolved oxygen for the Clam Bay
system.
Budget
.
The consultant will be compensated for labor on a time and material basis in the amount of
$64,498 with an additional amount of $12,650 to be used for direct expenses, for a total not-to-
exceed cost of $77,148. If directed to do so by the County, the amount of $12,650 for direct
expenses for bacterial source identification efforts can be removed from the budget amount and
