Transcript of State of California Lahontan Water Quality Control Board Update on Salt & Nutrient Management Plans.
State of CaliforniaLahontan Water Quality Control Board
Update on Salt & Nutrient Management Plans
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
Recycled Water Policy
• Goal is to increase the use of recycled water while protecting water quality
• Four Main Parts of Policy:
1. Mandates Increase in Recycled Water Use/Provides Incentives
2. Streamlines Permits/Clarifies Regulation
3. Addresses Constituents of Emerging Concern (CECs)
4. Requires Regional Salt/Nutrient Management Plans for all CA basins by 2014
Recycled Water Policy
Mandates 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
Recycled Water Policy
Streamlines Permit Process & Clarifies Regulatory Roles
• Provides shorter review and processing for permits
• Provides uniform interpretation of statutes, regulations, and policies
• Clarifies the roles of State Agencies
Recycled Water Policy
Establishes 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
Recycled Water Policy
Regional 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
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
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
Other Requirements
• Participation by Regional Board staff
• Basin Plan amendment
• 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
Initial Regional Board Process
Lahontan Region
About 24% of CA
< 2% of population
345 groundwater
basins/sub-basins
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
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
IRWM Regions & Priority GW Basins
• Lahontan BasinsHoney Lake
• Tahoe Sierra Tahoe North/South/West
Martis/Truckee
• Inyo MonoOwens, Indian Wells
• Fremont ValleyTehachapi
• Antelope ValleyAntelope
• Mojave BasinLower/Middle/Upper Mojave
Status for Priority Basins
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
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
Challenges
•No dedicated staff funding•How to implement plans•Few future funding sources•300+ “non-priority” basins•Many DACs
