Overview of Salt and Nutrient Management Plan Recycled Water Policy Requirement

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

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

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

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

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)

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

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

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

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

“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
