In February 2009, the State Water Resources Control Board (SWRCB) adopted, which established a statewide Recycled Water Policy. This policy encourages increased use of recycled water and local stormwater. It also requires local water and wastewater entities, together with local salt/nutrient contributing stakeholders to develop a Salt and Nutrient Management Plan (SNMP) for each groundwater basin in California. A was jointly prepared by the Central Basin and West Coast Basin Stakeholders and approved by the Los Angeles Regional Water Quality Control Board (LARWQCB) in December 2011.
The objective of the SNMP is to manage salts and nutrients from all sources "… on a basin-wide or watershed-wide basis in a manner that ensures attainment of water quality objectives and protection of beneficial uses." The SNMP will eventually be adopted by the LARWQCB as a Basin Plan Amendment. The SNMP will include the following:
- Stormwater and Recycled Water Use/Recharge Goals and Objectives
- Characterization of Hydrogeologic Conceptual Model/Water Quality
- Estimation of Current and Future Salt and Nutrient Loading
- Water Quality Monitoring
- Estimation of Basin Salt and Nutrient Assimilative Capacity (relative to Basin Plan Objectives)
- Antidegradation Analysis
- Development of Implementation Measures to Reduce Salt and Nutrient Loading
- CEQA Analysis of the Salt and Nutrient Management Plan
Participation by local agencies, communities, organizations, and other stakeholders is an important part of this process. Accordingly, a number of workshops have been and will be held to describe the plan development process and seek input from stakeholders. If you wish to be added to the list of stakeholders notified of workshops and webpage updates, please email your contact information to.

If you are interested in becoming a funding partner, would like to contribute to the Salt and Nutrient Management Plan development efforts, or have any general questions or comments, please email them to
The Salt and Nutrient Management Planning process moving forward is being led by Todd Engineers in cooperation with RMC Water and Environment, Nellor Environmental Associates, and ESA, and with the support, contributions, and guidance of the Central Basin and West Coast Basin stakeholders.
