  1. State of CaliforniaLahontan Water Quality Control Board Update on Salt & Nutrient Management Plans

  2. Overview • Brief Background of CA Recycled Water Policy • Salt-Nutrient (S-N) Plan requirements • How we are working with the IRWM groups in our Region for S-N planning • Status of S-N Plans

  3. Goal is to increase the use of recycled water while protecting water quality Four Main Parts of Policy: Mandates Increase in Recycled Water Use/Provides Incentives Streamlines Permits/Clarifies Regulation Addresses Constituents of Emerging Concern (CECs) Requires Regional Salt/Nutrient Management Plans for all CA basins by 2014 Recycled Water Policy

  4. Recycled Water PolicyMandates Increase in Recycled Water Use & Provides Incentives • Promote sustainable local water supply • Increase use by one million acre-feet per year by 2020 & at least two million acre-feet per year by 2030. • Priority funding for recycled water projects and storm water use projects

  5. Recycled Water PolicyStreamlines Permit Process & Clarifies Regulatory Roles • Provides shorter review and processing for permits • Provides uniform interpretation ofstatutes, regulations, and policies • Clarifies the roles of State Agencies

  6. Recycled Water PolicyEstablishes a program to evaluate the risks of Constituents of Emerging Concern(CECs) • CECs – what and why? • Advisory Panel, Report and Public Meetings Completed in 2010 • CECs amendment to Recycled Water Policy in 2012 • CECs in S-N Plans

  7. Recycled Water PolicyRegional Salt-Nutrient Management Plans • Salts and Nutrients – what and why? • Regional impacts, thus regional evaluation of groundwater and regional management plan • Locally driven, controlled and funded by water & wastewater entities, together with local salt/nutrient contributing stakeholders • Plans for all basin in the state by May 14, 2014 + 2 year extension

  8. Each S-N Plan Dependent on Site-Specific Factors • Size and Complexity of basin • Source water quality • Storm water recharge • Hydrogeology • Aquifer water quality • Watershed scale activities and stressors • May include other constituents

  9. Contents of S-N Plan • Basin-wide monitoring plan for salts, nutrients and other constituents • Annual monitoring of CECs • Goals and objectives for water recycling and stormwater recharge/use • Source identification, assimilative capacity, loading estimates, fate and transport • Implementation measures to manage loading on a sustainable basis • Antidegradation analysis

  10. Other Requirements • Participation by Regional Board staff • Basin Plan amendment

  11. Initial Regional Board Process • Staff participation • Regional Board members agree on S-N plan scope/concept prior to its completion (e.g. presentation of workplan outline at Regional Board meeting) • Focus future Regional Board review on plan content & not on scope of effort

  12. LahontanRegion • About 24% of CA • < 2% of population • 345 groundwater • basins/sub-basins

  13. Prioritization of GW Basins • Groundwater Ambient Monitoring and Assessment (GAMA) to ID Priority Basins • 12 in Lahontan Basin • North Lahontan (5) – Tahoe North/South/West; Martis/Truckee; Honey Lake • South Lahontan (7) – Owens, Indian Wells, Tehachapi, Antelope, Lower/Middle/Upper Mojave

  14. Overall Regional S-N Strategy/Approach • Priority Groundwater Basins - Work with Integrated Regional Water Management (IRWM) groups • Other Basins - Will address in groups as appropriate

  15. Lahontan Basins Honey Lake Tahoe Sierra Tahoe North/South/West Martis/Truckee Inyo Mono Owens, Indian Wells Fremont Valley Tehachapi Antelope Valley Antelope Mojave Basin Lower/Middle/Upper Mojave IRWM Regions & Priority GW Basins

  16. Lahontan Basins (Honey Lake) DWR grant Tahoe Sierra (Tahoe N/S/W ;Martis/Truckee) DWR grant Inyo Mono (Owens, Indian Wells) New Indian Wells Group Fremont Valley (Tehachapi) possible draft plan for Fremont Antelope Valley (Antelope) concept/scope to Board, DWR grant, draft plan Mojave Basin (L/M/U Mojave) concept/scope to Board; SEP Status for Priority Basins

  17. Our “Other” 333 Basins • Will address in groups as appropriate • Reduce the burden on rural communities in the more remote parts of our Region while encouraging water recycling & protecting groundwater quality

  18. Challenges • No dedicated staff funding • How to implement plans • Few future funding sources • 300+ “non-priority” basins • Many DACs
