Initial Conceptual Model (ICM)

Project Description: Development of the ICM is the first phase of a planned three-phased effort to develop the technical and regulatory basis for adoption of a Salt/Nutrient Management Plan (SNMP) for the Central Valley. The purpose of this phase is to develop a conceptual level (or 30,000 foot level) analysis of water balance and associated salt and nutrient (nitrate) conditions in the Central Valley. This effort will rely on the establishment of Initial Analysis Zones (IAZs) to complete water quantity and quality analyses within smaller areas within the valley and detailed analyses in two selected subareas of the Central Valley. The IAZs provide the foundation for the eventual establishment of salt/nutrient management zones in the Basin Plan. The outcome of the ICM project will be an assessment of salt/nitrate conditions in the Central Valley, including identification of hotspots and long term trends for salt and nitrate concentrations. Subsequent phases will refine the findings from the ICM and develop the SNMP which includes preparation of a salt/nitrate program of implementation and completion of regulatory analyses to support adoption of the SNMP into the Basin Plan.

Project Status: Project was initiated in September 2012 and completed in December 2013.

Phase 2 Conceptual Model

Project Description: Development of the Conceptual Model to support preparation of the Salt/Nitrate Management Plan (SNMP) was initiated under CV-SALTS’ Initial Conceptual Model (ICM) Project (completed in January 2014). This project builds off the findings of the ICM to begin development of a draft SNMP for the Central Valley. Scope of work elements include targeted refinements to the project database, development of salt and nitrate data analysis methods to support regulatory decisions, implementation of an archetype or pilot analysis to evaluate salt and/or nitrate management options at a management zone scale, and preparation of the first drafts of the technical elements of the SNMP.

Project Status: Project was initiated in April 2014 and completed in July 2016.

Phase 3 Conceptual Model

Project Description: Development of the Conceptual Model to support preparation of the Salt/Nitrate Management Plan (SNMP) was initiated under CV-SALTS’ Initial Conceptual Model (ICM) Project (completed in December 2013) and refined under the CV-SALTS’ Phase 2 Conceptual Model project (completed in July 2016). The Phase 3 work includes development of the Economics and Antidegradation Analyses being prepared to support adoption of the SNMP into the Basin Plan.

Project Status: Project was completed in December, see “CEQA/Economics/Antidegradation Analyses” under the CV-SALTS Documents Menu.

Salt and Nitrate Sources Pilot Implementation Study

Project Description: The Salt and Nitrate Sources Pilot Implementation Study (“Pilot Study) was the precursor to what is now described as the development of a Conceptual Model for the Central Valley. The primary objective of the Pilot Study was to develop a methodology and provide guidance for development of the Salt/Nutrient Management Plan for the Central Valley. Specifically, the project developed and documented methods to fairly and equitably quantify salt and nitrate sources. These methods were then pilot tested in selected Central Valley areas to evaluate their appropriateness for region-wide application. Following completion of the Pilot Study, CV-SALTS developed A Framework for Salt/Nitrate Source Identification Studies based on the findings from the Pilot Study.

Project Status: Project was completed in February 2010.
