Reingold, County Attorney EXHIBIT A SCOPE OF WORK INDIAN RIVER COUNTY UPPER FLORIDAN AQUIFER MODELING AND CONSUMPTIVE USE PERMIT MODIFICATION This Authorization, when executed, shall be incorporated in and become part of the Contract for Consulting/Professional Services between the Indian River County (County), and CDM Smith Inc. (Consultant), dated December 6, 2011, and the Extension and Amendment of Continuing Contract Agreement for Professional Services, dated November 4, 2014, hereafter referred to as the Contract. BACKGROUND The County owns and operates two Water Treatment Plants (WTP) which currently operate with 15 existing Upper Floridan Aquifer (UFA) production wells. The South County WTP relies on six existing (and one proposed) UFA production wells, while the North County WTP relies on nine existing UFA production wells. The County's existing Consumptive Use Permit (CUP) allows for a total, combined groundwater withdrawal allocation of 12.838 million gallons per day (mgd) with 6.4 mgd from the South County wellfield and 6.438 mgd from the North County wellfield (maximum withdrawal in year 2021) In 2009, the County completed a substantial expansion of the North County WTP to add five functional production skids (1 additional constructed, but not equipped with membranes for treatment). When operating at full capacity (seven treatment skids), the North County WTP would require approximately 12.6 mgd of raw groundwater. The ability to operate the WTP at capacity is limited by the 6.438 mgd North County wellfield groundwater allocation in the existing CUP. The County plans to modify the existing CUP to allow for full operation of the North County WTP and reflect the North County WTP as the primary production facility (with South County used as needed). The North County wellfield is historically more productive than the South County wellfield, and the newer North County WTP can be operated more efficiently than the South County WTP. The overall CUP combined average day withdrawal will not be significantly increased. The modification to the CUP described above will require revisions to the UFA groundwater model to include the increased allocation in the North County wellfield, to determine the impacts on existing legal and neighboring users (to the extent where information is available for non -CUP wells) and other potential water resources constraints. The following is the scope of services to be provided under this authorization for both the UFA model development and the CUP permit modification for submittal to the St. Johns River Water Management District (SJRWMD). SCOPE OF SERVICES Consultant will perform the following task services: TASK 1.0 COORDINATION WITH SJRWMD Subtask 1.1 Pre -Application Conference In accordance with the SJRWMD Applicant's Handbook, Consultant will request a pre -application conference with SJRWMD permitting staff to discuss the proposed modeling approach, need for the QUO Smith A-1 jj1703_Ltr with Exhibits.doc project and schedule for the permit modification. Consultant's Project Manager and modelers (2) will participate in the pre -application conference. Subtask 1.2 Preparation of Modeling Approach Memorandum In advance of the pre -application conference, Consultant will prepare a memorandum summarizing the proposed modeling approach to be used in support of the CUP modification. The memorandum will specifically identify the model(s) to be used, verification of the SEC model calibration, the groundwater withdrawal scenarios to be included and the report format to be submitted to SJRWMD. This document will be used at the pre -application conference to obtain input and consensus from the permit reviewers prior to commencing modeling activities. Subtask 1.3 Preparation of Permit Application Consultant will prepare and submit SJRWMD Form No. 40C-2 900(1)(e), Consumptive Use Permit for Public Supply — Form E. The application, per the Applicant's Handbook, will be required to include the following: • Historical water use; • Wellfield operating schedule; • Groundwater model summary report; and • Application fee. Preliminary discussions with SJRWMD permitting staff indicate that there will not be a requirement to update the water conservation plan, reuse feasibility study, population projections or unaccounted for water survey. If SJRWMD determines, upon submittal of the initial application, that these updates are required, additional services will be negotiated with the County prior to commencing additional work. Consultant will submit an electronic draft of the application to the County for review and comment prior to the submittal to SJRWMD. To the extent possible, consultant will submit the application and supporting documentation electronically through the SJRWMD e -Permitting system. Consultant will furnish the County with an electronic file of all documents submitted to SJRWMD in support of the application. The County will furnish the check for the permit application fee, to be submitted to SJRWMD by the Consultant. An application package will be submitted to SJRWMD within 120 days of receipt of the Notice to Proceed for this Work Order. Subtask 1.4 Response to Requests for Additional Information Consultant will respond to up to two requests for additional information (RAI) from SJRWMD, provided that neither request includes revisions to the modeling efforts. If additional modeling is required, an amendment to this Work Order will be negotiated prior to commencing work. This task assumes a level of effort to reply to each of the two RAIs of 16 hours (total 32 hours). If response to the RAI(s) requires a more detailed response than anticipated, Consultant will notify the County and negotiate the additional services prior to incurring additional costs. CDM Smith A-2 jj1703_1tr with Exhibits.doc Subtask 1.5 Review of Draft Permit Consultant will review the draft permit provided by SJRWMD prior to final issuance, on behalf of the County. Consultant will provide written comments to the County and SJRWMD (if needed) for incorporation into the final permit. Task 2.0 MEETING WITH SJRWMD Consultant will perform the required groundwater modeling for inclusion in initial permit application submittal to SJRWMD. Modeling will be performed using the Southeast -Central (SEC) MODFLOW model that has been developed and calibrated by SJRWMD. SJRWMD is continuing to improve the calibration of the surficial aquifer system by more refined inclusion of the surface water network in the model area using the MODFLOW RIVER package. The Consultant will use the most recent version of the model available at the time when modeling begins. This model covers all of Indian River and St. Lucie Counties, along with portions of Brevard, Highlands, Okeechobee, Osceola and Polk Counties. Consistent with all of the other regional models developed by SJRWMD, the model was calibrated to 1995 conditions, which is a baseline year in which there was abundant water use and hydrological data available to calibrate the model. The model includes a representation of the surficial aquifer, the Intermediate Confining Unit (Hawthorn Group), the UFA and Lower Floridan Aquifer. Calibration of the model will be verified to ensure that the difference between measured groundwater elevations and model computed groundwater elevations (residuals) are within acceptable range and that there is no spatial bias in these differences. The verified model will be used to perform up to five modeling simulations (one 1995 baseline pumping scenario and four proposed County pumping scenarios) to determine the optimum pumping rates that will maximize the withdrawal from North County wellfield, as agreed upon by the County and the Consultant. These five simulations will use different combinations of North County wellfield and South County wellfield withdrawals along with other permitted users within the model extent withdrawing at the permitted annual average allocation. Model simulations will be used to determine the effects, if any, from the pumpage of the County's wellfield(s) based on the following resources evaluation criteria: • No interference with other existing legal uses; • Cannot induce saline water intrusion; • Cannot create or contribute to pollution of the water resources; • Cannot adversely affect existing offsite land uses; • Cannot produce impacts to wetlands; and • No lowering minimum flow and levels for designated water bodies. Consultant will produce maps showing the anticipated cone of depression for each wellfield pumping scenario and contours of incremental and cumulative groundwater level drawdown due to pumping. These maps will be used in the evaluation of potential impacts to the resource evaluation criteria above. A technical memorandum describing the model that was used, results of model verification, a description of the simulations performed, the results of the modeling and impact evaluation including figures and tables will be submitted to the County for review and comment. The Consultant will review and incorporate County comments and finalize the groundwater modeling memorandum. This final technical memorandum will be used to support the application to modify the County's CUP modification for increased operational flexibility. cSmith A-3 jj1703_Ltr with Exhibits.doc TASK 3.0 PROJECT MANAGEMENT AND QUALITY CONTROL Activities performed under this task consist of those general functions required to maintain the project on schedule, within budget, and that the quality of the work products defined within this scope is consistent with Consultant's standards and the County's expectations.
