Other Treated Water Rates <br /> As part of the rate setting process the Board also adopts the Recharge Fee, In-Lieu Water <br /> Rate and Temporary Treated Rate. These rates are described in the following sections. <br /> Recharge Fee: <br /> The annual rate schedule includes a recharge fee for retailer pumping beyond their respective <br /> independent/groundwater pumping quota. The Recharge Fee applies only when Retailers <br /> exceed their respective groundwater pumping quota (GPQ). When Retailers pump beyond <br /> their GPQ, they are accessing Zone 7's water supply. The recharge fee includes the- entire <br /> cost of Zone 7's water system (i.e., treated water rate) less the costs of chemicals and power, <br /> which are not incurred by Zone 7 in the process of recharging the basin. Historically, this fee <br /> has been rarely used and then only for small quantities since Retailers generally do not exceed <br /> their independent quota. The fee has been applied once in the past five years. The current <br /> rate for CY 2022 is $1,471 per AF. The proposed rates for CY 2023-2026 under the three <br /> scenarios are shown in the table below: <br /> Scenario 4 - Chain of Lakes PFAS Project — SRF Loan Funding <br /> Calendar Year 2023 2024 2025 2026 <br /> Proposed Proposed Proposed Proposed <br /> Recharge Fee per AF $1,702 $1,638 $1,654 $1,714 <br /> Scenario 4B— 5.5% <br /> Calendar Year 2023 2024 2025 I 2026 <br /> Proposed Proposed Proposed Proposed <br /> Recharge Fee per AF $1,702 I $1,638 $1,654 i $1,714 <br /> Scenario 5 — Stoneridge PFAS Project— Reserve Replenishment <br /> Calendar Year 2023 2024 2025 2026 <br /> Proposed Proposed Proposed Proposed <br /> Recharge Fee per AF $1,732 $1,666 $1,679 $1,747 <br /> In-Lieu Water Rate: <br /> In the event staff concludes that surplus surface water is available and that it would be cost- <br /> effective to offer it to retailers at a reduced rate to achieve groundwater management <br /> objectives, in-lieu treated water could be offered. In-lieu water is treated water that the <br /> Retailers can purchase from Zone 7 instead of pumping their respective GPQ. This rate was <br /> established in 1993 to encourage artificial recharge when surplus surface water is available. <br /> The current rate for CY 2022 is $103 per AF. The rate is based on the projected power and <br /> chemical costs at the Del Valle and Patterson Pass Water Treatment plants and is proposed at <br /> $120 per AF for CY 2023-2026. <br /> Page 5 <br />
