Overview of Salt and Nutrient Management Plan

1. Overview of Salt and Nutrient Management Plan Recycled Water Policy Requirement

2. Overview of Presentation • Background of Recycled Water Policy & Salt/Nutrient Plan Requirements (SN Plan) • Adoption Schedule • Contents of SN Plan • Other Requirements • Prioritization of GW Basins • Regional Strategy/Approach • “Pre-adoption” understanding with Lahontan Regional Board

3. Background of Requirement for Salt/Nutrient Plans • State Water Board adopted the statewide Recycled Water Policy • Goal is to increase the use of recycled water while protecting water quality • Involvement by stakeholder groups to prepare SN Plans for each groundwater basin/sub-basin in the state • Collaborative processes open to all stakeholders; Lahontan to work with IRWM groups

4. Adoption Schedule for SN Plans • June 2012 Compile existing basin data, ID salt/nutrient sources, collect additional data • December 2013 Completed draft SN plan, CEQA, anti-degradation analyses • June 2014 Submittal of final SN plans to the Regional Board • June 2015 Regional Boards adopt SN plans as Basin Plan amendments • Time extensions of up to 2 years if demonstrating good progress

5. Potential Contents of SN Plan(required elements underlined) • Background (Stakeholder Roles and Responsibilities) • Groundwater Basin Characteristics (Basin Water Quality; Groundwater quality) • Basin Evaluations (SN balance including source ID, loading estimates, assimilative capacity, fate and transport; CECs) • Salt and Nutrient Management Strategies

6. Basin Management Plan Elements (Recycled Water and stormwater use/recharge goals and objectives; Basin Monitoring Program –ID who is responsible, WQ parameters, sampling frequency, Basin water and groundwater quality monitoring including areas of connectivity, large recycled water projects, recharge areas) • CEQA Analysis • Antidegradation Analysis • Plan Implementation (SN management programs; stakeholder responsibilities; implementation measures to manage SN loading)

7. Other Requirements • Participation by Regional Board staff • CEQA • Antidegradation analysis • Basin Plan amendment (i.e. regulatory action) – consider what is in the Basin Plan already for groundwater

8. Each SN Plan Dependent on Site-Specific Factors • Size • Complexity of basin • Source water quality • Storm water recharge • Hydrogeology • Aquifer water quality • Watershed scale activities and stressors

9. Prioritization of GW Basins • Groundwater Ambient Monitoring and Assessment (GAMA) • 14 in Lahontan Basin • North Lahontan – Tahoe North/South/West; Martis/Truckee; Honey Lake • South Lahontan – Owens, Indian Wells, Tehachapi, Antelope, Lower/Middle/Upper Mojave

10. Regional Strategy/Approach under Development • Work with IRWM groups to address priority groundwater basins on watershed scale for activities & stressors • SN might be an issue now or in the future • Areas with recycling • DWR’s Bulletin 118 groundwater basins • MUN designation • Surface water quality • Human activity/land uses

11. “Pre-adoption” understanding with Regional Board • Agreement on SN plan content prior to its completion (e.g., presentation of workplan, outline at Board meeting or workshop) • Focus Regional Board review and outcome & not on scope of effort
