Simulations 4 and 5 will be used by the CONSULTANT and OWNER in determining the groundwater level drawdown due to the total proposed IRCU EOP withdrawal (23.18 mgd) occurring from each wellfield. Since the relationship between pumping rate and groundwater level drawdown is linear in confined aquifers, the maximum pumping rate can be determined for each wellfield that will not impact other existing legal users of the UFA. Simulation 6 will be used as the baseline condition for determining cumulative drawdown. The deliverable for this task will be maps showing the cone of depression (groundwater level drawdown) for each wellfield pumping scenario and contours of cumulative groundwater level drawdown due to pumping. The results of these Simulations 4 and 5 are for internal purposes only and will not be submitted to SJRWMD in the groundwater modeling and impact evaluation TM and/or described in the revised groundwater modeling plan. The results of Simulation 6 will be submitted to SJRWMD in the groundwater modeling and impact evaluation TM and described in the revised groundwater modeling plan. TASK 2 - PREPARATION OF REVISED GROUNDWATER MODELING PLAN The CONSULTANT will modify/update the existing groundwater modeling plan developed and approved by SJRWMD in 2016 to describe the three simulations listed in WO No. 5 and the methodology and data to adjust the agricultural pumping from legal users in the model domain. The draft modeling plan will be submitted to the OWNER for review and comment. The CONSULTANT will incorporate comments provided by the OWNER into the plan and send the final plan to SJRWMD for review and approval before starting the model simulations. TASK 3 - PROJECT AND QUALITY MANAGEMENT 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 Work Order is consistent with CONSULTANT's standards and the OWNER's requirements. Specific activities included are identified below: Subtask 3.1 - Project Quality Management CONSULTANT maintains a Quality Management System (QMS) on all projects. In accordance with the QMS, a project planning and scope review meeting will be conducted at the start of the project. In addition, the CONSULTANT's Technical Specialists will perform quality reviews of the deliverables identified in Task 1. Subtask 3.2 - Project Status Reports CONSULTANT's project manager will prepare and submit monthly written status reports with each invoice for an anticipated project duration of 4 months. OTHER SERVICES NOT INCLUDED IN THIS WORK ORDER This Work Order does not include the following items: • Preparation of a Consumptive Use Permit application or permit fee; or • Modeling changes for SJRWMD Requests for Additional Information. OWNER's RESPONSIBILITIES The OWNER will provide all available data requested by the CONSULTANT for the purpose of completing the aforementioned tasks. The data necessary for this project are, but not limited to the following: CDM Smith Page 3 of 4 jj2688_Exhibit A.docn
