Central Valley Sustainable Alternatives for Long Term Salinity (CV-SALTS)

LWA has been actively involved in and completed projects for CV-SALTS for over five years. Our Team for these projects includes Carollo Engineers, Kennedy/Jenks Consultants, Systech Water Resources, PlanTierra, Luhdorff and Scalmanini Consulting Engineers, Giorgos Kourakos, Formation Environmental, and Ascent Environmental.

Our involvement includes participation in the Executive Committee, Technical Advisory Committee (TAC), and Knowledge Gained Subcommittee as well as work on the Salt and Nitrate Sources Pilot Implementation Study (February 2010), the Knowledge Gained Subcommittee memo, A Framework for Salt/Nitrate Source Identification Studies (December 2011), the Initial Conceptual Model (ICM) (December 2013), the Geographic Information Services (January 2014), the development of water quality objectives for salinity on the Lower San Joaquin River (LSJR) (ongoing), the development of a Preliminary Draft Salt and Nitrate Management Plan (SNMP) (ongoing), and the development of supporting information for the proposed de-designation of the MUN and AGR beneficial uses in the Tulare Lake Bed (ongoing).

The development of a SNMP for the entirety of the jurisdiction of the Central Valley Regional Water Quality Control Board is ongoing and has occurred in the following phases:

  • Phase I (2012-2013) included development of an Initial Concept Model (ICM) which is a concept level analysis estimating salt and nitrate load balances for the Central Valley floor in 22 areas that are referred to as Initial Analysis Zones (IAZs).
  • Phase II (2013-2015) includes development of the preliminary draft SNMP which utilizes data collected and/or organized in Phase I to identify the approach and establish the basis for the short and long term management of salt and nitrate in the entirety of the Central Valley region. The SNMP will form the basis for corresponding amendments to the Water Quality Control Plans for the Sacramento/San Joaquin Basin and Tulare Lake Basin.
  • Phase III (2015-2017) will focus on work to support the additional required elements of the SNMP and Basin Plan amendments, such as refinement of the preliminary draft SNMP, development of a monitoring/surveillance plan, as well as development of documents that are necessary under the California Water Code and Clean Water Act for the regulatory approval process for the adoption of the SNMP and corresponding Basin Plan amendments (anti-degradation analysis, the economic analysis of implementation alternatives, CEQA analysis).

It is anticipated that upon completion of Phase III and the adoption of the comprehensive SNMP, local SNMPs may be developed and implemented by local/regional entities, as needed. The local SNMPs will be informed by prototype and archetype methods, as well as the implementation measures recommended in the final, adopted SNMP.
