AGENDA. ITEM: Contract for Effiuent Copper Mixing Zone, Phase I
RFF' No. 0203-7
SUBMITTED BY: Donna Kaluzniak, CEP, Utility Director~.~ J
DATE: Junf: 16, 2003 ~
BACKGROUND: On .June 9, 2003, the City Commission authorized staff to negotiate a
contract with Camp, Dresser & McKee (CDM) to conduct a study in order to obtain att effluent
copper mixing zone from the Department of Environmental Protection (DEP). The study will be
conducted in two phases, l~s per RFP No. 0203-7. Phase I consists primarily of samplvlg,
analysis, and development of a modeling workplan to submit for DEP's approval. Pha::e II will
consist of modeling and permit modification activities after DEP's review of the data and
modeling p]an.
Staff has negotiated a prier, for Phase I of the contract for the Effiuent Copper Mincing :Lone in the
amount of $32,680.
BUDGET: Funding for Phase I of the Effluent Copper Mixing Zone is available in the Sewer
Fund, miscellaneous professional services, account nos. 410-5506-535-31-00 and 410-5508-535-
31-00. The project will be funded by all three beach cities as follows:
Treanment Plant Design Flow,
MGD
Total = 10.9 Percent of Total of All 4
Treatment Plants Cost for Phase I ofthe
E&Iuent Copper Mixing
Zone Stud .
Jacksonville Beach 4.5 41.3% $13,49b.84
Ne tune Beach 1.5 13.7% $4,477.16
""Atlantic Beach 4.9 45% $14,706.00
''Total of Wastewater Plant #1 (3.0 MGD) plus Wastewater Plant #2 (1.9 MGD)
RECOMMENDATION: Award the contract for Effiuent Copper Mixing Zone, Phase I, to
Camp, Dresser & McKee in the amount of $32,680.

Subject: Mixing Zone Analysis
Dear Ms. Kaluzniak:
Thank you for the opportunity to assist the City of Atlaric Beach in addressing the perntit
compliance issue with copper discharge concentrations from your wastewater treatment
plants (W WTPs) and those of the other Beach communises. As we undezstand it, Hie issues
areas follows:
^ The Cities of Atlantic Beach, Neptzme Beach, and Jacksonville Beach own and operate their
own W WiI's
^ The effluent kom one of Atlantic Beach's W WfP combines with the effluent fzoxn the
W WTPs of Neptune Beach and Jacksonville Beach before being dischargedmto the St.
Johns River through a common outfall
^ Effluent from Atlantic Beach's Bucaneer W WTP discharges adjacent to the common outfall
from the three W WTPs
^ Copper concentrations from aII W WTPs periodically exceed the State of Florida surface
water dixharge Limit of 29 parts per bfllfon (ppb)
^ Mercury concenizaiions from Atlantic Beach's two (2) W WTPs have periodicall}~ exceeded
the State of Florida surface water discharge Limit of 0.025 ppb
As ouHlned in our proposal, we have proposed a two step approach for d~**r++*+~ng the
feasibility of obtaining a mixing zone:
1. To sample the effluent from the W W'TPs and the water at and in the vicinity of the
outfall for 20 days and vse the data to preli:a+inarily assess if a mixing zone: is feasible

2. If feasible, model and permit the mi~dng zone for the two outfalls as if [he discharge
was front a single outfall
Camp Dresser & Mckee Inc. (CDM) is pleased ib provide you with a scope and fee proposal
for sampling, laboratory services, Preliminary engineet9rtg, and PREP meetings to
prelirrdnarily assess fhe feasibiliry of obtaining a mixing zone for copper and potentially
mercury at the point of discharge to the St. Johns River as s++TMm=*+>ed in the first step of our
approach outlined above CDM has trot considered the need for a mixing zone for mercury
and no sampling actlvities or feasibility analyses for a mercury mixing zone is included itt our
scope.
Scope of Services
7o complete step 1 0£ our approach and to preliminarily assess if a mixing zone is even
feasible, CDM will provide the City of Atlantic Beach (City) with the following tasks:
1. Attendance at a coordination and review meeting with FDEP staff to swr*n~++~e
and confirm the approach
2. Prepare a letter to the Florida Department of Environmental Protection discussing
the plan of action for sampling
3. A 2o-day sampling activity and laboratory analysis of samples
4. Two (2) meetings with the FDEP to review data from the samgling evetrt and
discuss the feasibility of obtaining a aiazng zone. Summary letters to F1~EP from
both meetings are also included in our scope
5. Development of a workplan for step 2 of our approach to model the outfall for a
u+ixing zone (if deemed feastble in Task 4)
Task 1: Sttmma-y Letter to FDF.P regarding grojeet coordination actiaities
CDM will author a 1 to 2 page letter to fire PREP summarizing the approach and significant
issues ducwsed with the FDEP std representatives from the Cities, and CDM
Task Z• Samyltr~ Platt of Action Letter to F!?F.P
Under this task CDM wfll first develop a sampling plan for the W WTPs and the outfalL
Otttfall sampling locations wr71 include three locations that will allow our team to best
characterize the feasibility of obtaining a mixing zone. CDM wiIl then provide a letter to the

kI7EP detat7ittg the approach for sampling and data collection. A telephone conversation will
be conducted with FDEP representatives to receive F171=P comments on our sampling plan.
For purposes of developing this scope, it is assumed that FDEP will not deviate kont its
position on sampling and data collection as defined in our project coordination meeting.
Task 3: SampIistg Regiment and Laboratory Analyses
CDM will take samples once a day, for twenty (20) consecutive days at the above mentioned
wastewater treatment plants for total and dissolved copper. Flow data from trealm.ent plant
operational staff wiIl be provided to CDM for use 3tt the analysis- The total number of samples
from the #our W WT7?s over 20 days is eighty (80).
CDM will also saanple at the St Johns River oulfall every other day £ot 20 days. Data to be
collected will include the foIlowing:
^ Tidal information
^ River velocity
^ Rainfall
^ Total and dissolved copper concentrations at the outfall. Measurements shall be done at
mid-depth One grab sample shall be taken per sample event
^ Total and dissoh>ed copper concentrations at approximately 30 to 60 feet from the outfall
Measurements shall be done atmid-depth. One grab sample shaII be taken per sample
event.
CDM will coordinate with an independent laboratory to analyze the samples taken daring-rite
testing. CDM wiIl also analyze e~dstittg water quality data that may be available for the area
within 300 feet of the ontfalL
Task 4 Summary Meetings With the TAEP to Discuss Resuiis
CDM will attend up in two meetings with the FDEP to discuss the results of the sampling and
data analysis. CDM. wiIl prepare summary letters from each meeting to FDEP.
Task 5: Workplan for mixittg zoxe (if requiretA
Under this tally CDM will develop a workplan to model a atixing zone for copper. This plan
willinclude model selection. permi4ting strategy development, and coordination with FDEP
to ensure that the model outputs will be acceptable to FDEP. From this workpIa~t, CDM wilt

work with the City to develop a scope of services and #ee proposal for the modeling work
necessary for the mixing zone determination.
Schedule
CDM will provide the services as described herein within 90 days upon approval of work
authorization and notice to proceed from the City.
Fee
CDM will perform the professional engineering services as outlined in this proposal for a
lump soot fee of $20,7.30. In addition, CDNI wdl engage the services of Environmental
Conservation laboratory, Inc. for the analytical work in the amount of $3,300; a:td Dial
Cordy and Assodates, lttc. for river sampling and data coIleclion in the amount of $9,250.
Tate total compensation for the work of the first phase is a lump sum fee of $32,f~80. CDM will
