CV SALTS Prioritization & Optimization Study Year 1 Progress Report

CV-SALTS Central Valley Region Salt & Nitrate Control Program Surveillance and Monitoring Program

Central Valley Salinity Alternatives for Long-Term Sustainability (CV-SALTS) | February 3rd, 2023

The prioritized Nitrate Control Program and phased Salt Control Program are designed to address both legacy and ongoing salt and nitrate accumulation issues in groundwate

The prioritized Nitrate Control Program and phased Salt Control Program are designed to address both legacy and ongoing salt and nitrate accumulation issues in groundwater and salinity concerns in surface waters. However, the primary focus of early actions being implemented under the Nitrate Control Program (i.e., the first ten years) is on groundwater quality and in particular nitrate impacts to drinking water supplies. The overarching management goals and priorities of the SNCP are to: Ensure safe drinking water supply; Reduce salt and nitrate loading so that ongoing discharges neither threaten to degrade high quality waters absent appropriate findings by the Central Valley Board, nor cause or contribute to exceedances of water quality objectives; and Implement long-term, managed restoration of impaired waterbodies.

The purpose of Prioritization & Optimization (P&O) Study Task 5.3 (Information Extraction from Groundwater Sustainability Plans [GSP]) is to extract and organize relevant GSP data and information that can be used to (1) validate or refine information contained in the P&O Study’s CV-SWAT watershed model (developed to support ongoing baseline characterization work); (2) support the eventual development of salinity management alternatives within specified planning areas; and (3) help ensure that long-term Central Valley salt planning considers ongoing Groundwater Sustainability Agency (GSA) planning efforts, which is of particular interest to the State Water Resources Control Board.

The purpose of Prioritization & Optimization (P&O) Study Task 5.3 (Information Extraction from Groundwater Sustainability Plans [GSP]) is to extract and organize relevant GSP data and information that can be used to: Validate or refine information contained in the P&O Study’s Central Valley Soil and Water Assessment Tool (CV-SWAT) watershed model and other models (developed to support ongoing baseline characterization work and future salinity-related analyses); Support the eventual development of salinity management alternatives within specified Central Valley planning areas; and Help ensure that long-term Central Valley salt planning understands and considers ongoing Groundwater Sustainability Agency (GSA) planning efforts, efforts and potential future conditions of the water in the Central Valley region and benefits from the local investment in these plans. It is also expected that this report will be a foundation for enhanced coordination with GSAs as planning occurs in their regions.

The Nitrate Control Program is designed to achieve the following three management goals in the Central Valley Region: Goal 1 – Ensure a safe drinking water supply; Goal 2 – Reduce salt and nitrate loading so that ongoing discharges neither threaten to degrade high quality waters absent appropriate findings by the Central Valley Water Board nor cause or contribute to exceedances of water quality objectives; and, Goal 3 – Implement long-term, managed restoration of impaired water bodies.

CV-SALTS Prioritization & Optimization Study: Final Baseline Characterization Report

Central Valley Salinity Alternatives for Long-Term Sustainability (CV-SALTS) | March 9th, 2024

The Central Valley Regional Water Quality Control Board (Central Valley Water Board) first adopted a three-phased Salt Control Program into the water quality regulations

The Central Valley Regional Water Quality Control Board (Central Valley Water Board) first adopted a three-phased Salt Control Program into the water quality regulations applicable to the Central Valley Region of California in 2018; these regulations were subsequently amended in 2020. Phase I of the Salt Control Program requires implementation of the Prioritization and Optimization (P&O) Study. The primary purposes of this Study are to characterize existing salinity conditions in surface water and groundwater in the Central Valley Region, establish appropriate salinity targets for the protection of beneficial uses, and facilitate the development of long-term salt management alternatives for implementation in Phases II and III of the Salt Control Program.

Section 7.0 of the Conservation Strategy describes regional permitting efforts that are being developed by the California Department of Water Resources (DWR) in various stages of implementation. This appendix provides a more thorough description of the State and federal regulatory approvals that will be required for implementation of the Central Valley Flood Protection Plan (CVFPP), including the Conservation Strategy.

CVFPP Conservation Strategy Appendix B. Advance Mitigation

Section 7.0 of the Conservation Strategy presents methods for coordinating the acquisition of permits for implementation of the Central Valley Flood Protection Plan (CVFPP). These approaches have been initiated and are expected to be used in the future to mitigate impacts on species and habitats that result from CVFPP actions. As explained in Section 7.0, one regional permitting tool used by the California Department of Water Resources (DWR) is the development of advance mitigation projects.  This appendix further describes the purpose and benefits of advance mitigation, DWR’s efforts to date, and the process for selecting the first set of advance mitigation projects that will support the CVFPP. Each advance mitigation project has been, or will be, carefully selected in collaboration with permitting agencies to mitigate the effects of activities that will be implemented by DWR and Local Maintaining Agencies in the Systemwide Planning Area (SPA). DWR and the resource agencies are continuing to develop the mechanisms for crediting and a process for tracking the credits. Future advance mitigation projects are likely to follow the same process described herein.
