Flow Meter Accuracy Report Form (EN-51) must be submitted to the District within 30 days of the inspection/calibration. 25. The permittee must maintain all flowmeters and alternative methods for measuring flow. In case of failure or breakdown of any meter, the District must be notified in writing within 5 days of its discovery. A defective meter must be repaired or replaced within 30 days of its discovery. 26. The permittee must implement the Water Conservation Plan submitted to the District on September 26, 2023, in accordance with the schedule contained therein. 27. The permittee must have in place a process for reporting, recording and documenting unmetered water uses including, but not limited to, main breaks, sewer cleaning, and water quality flushing. 28. The permittee must conduct a detailed water audit every five years and submit it to the District by February 28th of 2030, 2035, 2040, and 2045. All water uses given in the audit must be for the previous calendar year and documentation provided on how the amounts were metered or determined. If the water audit shows that the system losses and unaccounted for water utility uses exceed 10%, the permittee must submit an annual corrective action plan and annual water audit to the District until the water audit shows the system losses and unaccounted for water utility uses do not exceed 10%. 29. The permittee must submit to the District a 10-year compliance report pursuant to subsection 373.236(4), F.S., during the term of the permit. The permittee❑must submit the report by May 13, 2035. The report shall contain sufficient information to demonstrate that the permittee's use of water will continue, for the remaining duration of the permit, to meet the conditions for permit issuance set forth in the District rules that existed at the time the permit was issued for 20 years by the District. At a minimum, the compliance report must include: a. documentation verifying the permittee's use of water is efficient and continues to meet the demands of the service area; b. documentation verifying the permittee is implementing water conservation measures identified in the Water Conservation Plan submitted to the District on September 26, 2023; c. documentation verifying that the permittee's groundwater pumping has not caused to contributed to groundwater quality changes; and d. information demonstrating that the lowest quality source of water available, including reclaimed water, is being used to meet water demands unless demonstrated that such use is not feasible. 30. The permittee shall use the lowest quality water source, such as reclaimed water, surface/storm water, or alternative water supply, to supply the needs of the project when deemed feasible pursuant to District rules and applicable state law. 31. During the construction of any proposed well the permittee must conduct the following tests and submit the testing results to the District within 90 days of completion of the testing: (a) Downhole field water quality testing for chlorides, sulfates and specific conductivity taken during drilling, at the end of each drill rod or 30-foot intervals, upon penetration of the Floridan aquifer, or when the drilling method changes from mud-rotary to the reverse- air/direct-air drilling technique. Any change in these parameters of 20% or greater between consecutive samples will require that the permittee collect a sample for laboratory analysis for those major anions and cations listed in Appendix F of the Applicant's Handbook. All major ion analyses must be checked for anion-cation balance and must balance within 10%. It is recommended that duplicates be taken to allow for laboratory errors or data loss. (b) A suite of geophysical logs (gamma, electrical resistivity, caliper, flow, and fluid resistivity) and a video log of the well. All logs must be submitted to the District in hard copy and electronically in LAS format. (c) GPS (latitude, longitude) and a site map location of the well. (d) Water quality testing upon completion of the well for: Field o Field temperature (°C) o Field pH o Field specific conductance (umhos/cm) o Field turbidity (NTU) Laboratory Calcium (mg/L), Magnesium (mg/L), Potassium (mg/L), Sodium (mg/L), Total iron (mg/L), Chloride (mg/L), Sulfate (mg/L), Strontium (mg/L), Bicarbonate Alkalinity (as mg/L CaCO3), Carbonate Alkalinity (as mg/L CaCO3), Total Dissolved Solids (mg/L), Specific Conductance (umhos/cm or uS/cm) Sample Collection Groundwater samples must be collected in accordance with the Florida Department of Environmental Protection's (FDEP) standard operating procedures (SOP), DEP-SOP- 001/01, DEP Quality Assurance Rule, 62-160, F.A.C. The well must be purged in accordance with the appropriate procedure in DEP-SOP- 001/01, as necessary to evacuate water from the well column and induce groundwater representative of the hydrogeologic formation into the well prior to sampling. Purged water must be sampled and analyzed in the field for the following parameters: o Water Temperature (°C) o pH (SU) o Specific Conductance (umhos/cm or uS/cm) o Turbidity (NTU) Purging must be documented using the Groundwater Sampling Log form referenced in the FDEP SOP or equivalent. Water samples must be stored on ice immediately after collection and remain on ice until received by the laboratory. It is recommended that sample duplicates be taken to allow for laboratory errors or data loss, and these samples be stored by the laboratory for a minimum of 60 days to ensure backup sample availability should re-analyses be required. Quality Assurance The permittee must provide documentation that field instruments were properly calibrated prior to obtaining field measurements during purging and sampling. All water quality analyses must be performed by a laboratory certified by the Florida Department of Health (FDOH) and the National Environmental Laboratory Accreditation Program (NELAP). All laboratory analyses must be by methods for which the laboratory has FDOH certification. All laboratory analyses must be completed within EPA holding times. If data is lost or a laboratory error occurs and the EPA holding time for an analysis has expired, the permittee must have the well re-sampled within 15 days of notification from the laboratory that a loss or laboratory error has occurred. The resample shall be collected according to the procedures described above, and analyzed for the field parameters and the major ion suite listed above. With the exception of pH, laboratory analyses utilizing selective ion electrodes are not acceptable due to the inadequate sensitivity of these methods. Analyses utilizing test kits typically used for field screening (e.g., Hatch and LaMotte) are also not acceptable for the same reason. All major ion analyses must be checked for anion-cation balance (equivalent concentration in meq/L) and must not exceed 5% difference. If the ion balance exceeds 5% difference, the permittee must review the data and include in the report submitted to the District, a discussion of the cause or explanation of the imbalance. The permittee may also be required to have the sample re-analyzed if it is within acceptable holding times or have the well re-sampled. The resample shall be collected according to the procedures described above and analyzed for the four field parameters and the major ion suite. Reports A report must be submitted to the District within 30 days of receipt of data analysis from the laboratory. The report must include the following: o Table summarizing results for field measurements and laboratory chemical analyses o Well sampling log o Field instrument calibration verification o Chain of custody forms (if outsourced) o Laboratory analytical report (if outsourced) All data must be submitted to the District in a District-approved electronic format readable by the District's computerized database. 32. Permittee's total required offset (or"lift") to address its proportionate share of impact to Lakes Brooklyn and Geneva minimum flows and levels (MFL) as established by rule 40C- 8.031(5), F.A.C., effective September 28, 2021 is 0.67 feet which is comprised of 0.12 feet resulting from Permittee's average water use for the years 2014-2018 and 0.55 feet for Permittee's water use over and above the years 2014-2018. The determination of the amount of lift needed to offset the impact on Lakes Brooklyn and Geneva MFLs from Permittee's water use is based upon the Permittee's withdrawal scenario reflected in Exhibit "B" to Cost Participation Agreement No. 4 for Construction and Operation and Maintenance of the Black Creek Water Resource Development Project (Cost Participation Agreement) and the North Florida Southeast Georgia Regional Groundwater Flow Model version 1.1 (NFSEG) in combination with the KHTM local scale model version 2.0 simulation run by the District on June 25, 2021, and provided to the Permittee on June 30, 2021, which included a future water use scenario of 24 MGD. The files associated with this model simulation have been filed with District Item no. 1426562 and have made a part of the application file for permit no. 416-49. Permittee has elected to participate financially in the construction and operation of the Black Creek Water Resource Development Project as a means of addressing its proportional share of the required recovery of the MFLs for Lakes Brooklyn and Geneva and to ensure its future water use as specified above complies with the Lakes Brooklyn and Geneva MFL criteria by not causing a violation of the Lakes Brooklyn and Geneva MFLs. Permittee has entered into the Cost Participation Agreement with the District, to purchase 0.67 feet of lift associated with the Black Creek Water Resource Development Project. Permittee is, therefore, in compliance with the Recovery Strategy for Implementation of the Minimum Levels for Lakes Brooklyn and Geneva, condition 10 of CUPs 416, 51227, and 137335 as well as condition 29 of CUP 431 and the requirements of Rule 40-2.301(2)(h), F.A.C., and sections 2.3(h) and 3.8 of the Applicant Handbook: Consumptive Uses of Water (August 29, 2018), relative to the Lakes Brooklyn and Geneva MFLs up to the 0.67 of lift purchased. If Permittee elects to modify its wellfield positions as shown in Exhibit "B" to the Cost Participation Agreement or its wellfield operation plan in a manner that materially deviates from the aforementioned model simulation Permittee and the District will use the North Florida Southeast Georgia Regional Groundwater Flow Model version 1.1 (NFSEG) in combination with the KHTM local scale model version 2.0 to determine if any additional deficit in the Lakes Brooklyn and Geneva MFLs will be caused by Permittee' s revised wellfield locations and operation plan. Upon mutual agreement of the District and Permittee, alternative groundwater flow models or future updates to the NFSEG Model version 1.1 or KHTM local scale model version 2.0 may be utilized for the determination of deficits and lift. The Permittee is on notice that it must receive all other required authorizations, including permit modifications, to authorize the wellfield withdrawals identified in the aforementioned model simulation.
