analysis. Additional modeling simulations are therefore necessary to determine whether the new <br />demand of 23.81 mgd will cause any adverse impacts to water resources, environmental resources, and <br />other legal users. <br />This Work Order has been developed to provide the groundwater modeling services with the new <br />projected 2050 demands in support of the CUP modification. , <br />SCOPE OF WORK <br />The following is a description of the work to be provided under this Work Order. <br />TASK 1- GROUNDWATER MODELING AND IMPACT EVALUATIONS <br />The CONSULTANT will perform the required groundwater modeling for inclusion in the initial permit <br />application submittal to SJRWMD. Modeling will be performed using the modified ECFM for the <br />increased UFA allocation and COUAQ model to determine impacts on the SAS consistent with the 2016 <br />modeling and be required by SJRWMD for.the 2020 CUP application. These models were used during <br />previous permit modification attempt in 2016 that were initially accepted by SJRWMD. <br />Up to three (3) groundwater modeling simulations will be performed using the End -of -Permit (EOP) <br />withdrawals for all permitted users, IRCU wells pumping at 0 mgd, and at the requested allocation <br />increase of 23.81 mgd. These three simulations are listed below: <br />1. Simulation 1 (SIM 1) — IRCU wells and other legal user wells within the model domain pumping at <br />their current EOP withdrawal rate. The CONSULTANT has received a geodatabase from <br />SJRWMD containing EOP withdrawals for all permitted users within the model domain. <br />Simulation 2 (SIM2) — IRCU wells pumping turned off (0 MGD) and other permitted user wells <br />within the model domain pumping at their current EOP withdrawal rate. SJRWMD no longer <br />uses 1995 conditions as baseline conditions and uses "pumps off' (0 mgd) for the applicant's <br />withdrawal for this simulation. <br />3. Simulation 3 (SIM3) — IRCU wells pumping at their requested withdrawal rate for 2050 (23.81 <br />mgd) and other permitted user wells within the model domain pumping at their current EOP <br />withdrawal rate. <br />These simulations are consistent with the requirements outlined by the SJRWMD in an email dated <br />October 30, 2019. The latest EOP water use withdrawal database will be obtained from the SJRWMD for <br />other permitted users. The wells from this database will be compared to the permitted user wells used <br />during the previous modeling in 2016. Any wells that have been abandoned or capped since 2016, will <br />be removed from the model while any wells that have been permitted since 2016 will be added to the <br />model. <br />The distribution of the 2050 (SIM3) pumping rate between IRCU North and South wellfields will be made <br />after consultation with the OWNER. <br />Model simulations will be used to determine the effects, if any, from the pumpage of the OWNER's <br />wellfield(s) based on the following resources evaluation criteria: <br />CDM <br />Smith 105 <br />
