Exh 4BAGENDA ITEM 4B JUNE 23, 2003 CITY OF ATLANTIC BEACH CITY COMMISSION MEETING STAFF REPORT 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 .

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 consulting • anglrwcrlsq • wnssruRlvn • PP9nslone AGENDA ITEM 4B JUNE 23, 2003 Ms. Donna lCaluzr~iak J~ is, zoos Page 2 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 AGENDA ITEM 4B JUNE 23, 2003 ~~ t Ms. Donna 1Caluznia>a. June 13, 2003 Page 3 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 AGENDA ITEM 4B JUNE 23, 2003 ~• Ms. Donna Kaluztuak June 13, 2003 Page 4 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 invoice the City monthly as costs for our services are intuited. Thank you for the opportunity to assist you with your feasibility study. Please €~ve me a caIl if you have any questions. Very y yo , onald E Maur r, P.E., DEE Assoaate Camp Dresser & McKee Yxtc.
