Introduction to the S ustainable Groundwater Management Act

The S ustainable Groundwater Management Act (S GMA)  S ustainable Groundwater Management Act (S GMA) was passed by the California legislature in 2014  Created a framework for sustainable groundwater management in California  Sustainable Groundwater Managemen t = “ Management and use of groundwat er in a manner t hat can be maint ained during t he planning and implement at ion horizon wit hout causing undesirable result s.” “ … groundwat er management in California is best accomplished locally.” – Governor Jerry Brown, S ept ember 2014

S GMA  Requires the formation of Groundwater S ustainability Agencies (GS As) – generally agencies overlying the groundwater basin  GS As are responsible for preparing Groundwater S ustainability Plans (GS Ps) and be submitted by:  January 2020 for critically over drafted basins  January 2022 for remaining high and medium priority basins  Creates a single sustainability goal for the basin or subbasin  Achieved within 20 years of GS P implementation  Maintained without causing undesirable results

S GMA Two main goals to promote basin health: 1. S top overdraft by “ balancing the water budget” 2. Achieve sustainable yield and avoid six undesirable results Surface Water Lowering Seawater Land Degraded Reduction Depletion GW Levels Intrusion Subsidence of Storage Quality

Basin Prioritization  Four groundwater basin categories: High, medium, low, and very low  Based on components in California Water Code S ection 10933(b)  Population overlying basin or subbasin  Number of wells that draw from the basin  Irrigated acreage overlying the basin  Reliance on groundwater for primary source of water

Groundwater S ustainability Agencies  S GMA Required Groundwater S ustainability Agencies (GS As) be formed  Expanded the role of DWR to support local implementation of sustainable groundwater management by GS As  Allows for intervention by the S tate Water Resources Control Board (S WRCB) at points throughout the process of achieving sustainable groundwater management

Powers and Authority of a GS A  Adopt rules, regulations, ordinances and resolutions to achieve groundwater sustainability  Conduct investigations for the purpose of:  Determining the need for groundwater management  Preparing and adopting a GS P and implementing rules and regulations  Proposing and updating fees  Monitor compliance and enforcement  Inspection of property or facilities to ascertain compliance  Require registration of a groundwater extraction facility  Require measurement and recording of groundwater extraction (costs borne by owner or operator)  Require groundwater extraction facilities to file an annual report

Powers and Authority of a GS A (continued)  Acquire land, water rights, rights-of-way, structures, or other property  Appropriate and acquire surface or groundwater (or rights thereof)  Transport, reclaim, purify, desalinate or treat wastewater or polluted water  Additional authorities  Regulate or limit groundwater extractions  Limit construction of new wells, or reactivation of older wells  Authorize transfers and carryover of groundwater extraction allocations

Groundwater S ustainability Plan  GSP development must be a transparent and open process encouraging stakeholder and public input  Establish minimum thresholds for each sustainability indicator to avoid undesirable results

Bedford Coldwater Groundwater S ustainability Authority

Bedford Coldwater Groundwater S ustainability Authority  Joint Powers Authority (JP A) formed by three local agencies in February 2017 for management of the S ubbasin  City of Corona City of Corona  Elsinore Valley Municipal Water District  Temescal Valley Water District Jacque Casillas, Director  JP A signed a resolution in March 2017 to become the GS A for the S ubbasin TVWD EVMWD  Governed by a representative Board member from each agency Phil Williams, Vice-Chairman Paul Rodriguez, Chairman

Bedford Coldwater GSA Basin and Agency Boundaries

Bedford Coldwater S ubbasin Prioritization  Bedford Coldwater S ubbasin classified as a very low priorit y subbasin  Groundwater use <9,500 acre-feet per year and no documented impacts to the subbasin DWR SGMA Basin Prioritization Tool

2017 Prop 1 S GWP Grant  BCGS A was awarded funding by the Department of Water Resources (DWR) of the S tate of California through the Proposition 1 S ustainable Groundwater Planning (S GWP) Grant  S GWP Grant provides funding to assist in financing the planning and/ or selected proj ect activities that will improve sustainable groundwater management  BCGS A submits quarterly progress reports to DWR under the conditions of the grant

GS P Development The First S tep is a Conceptual Model

GS P Development A Water Budget is Key to the Conceptual Model

GS P Development From Conceptual Model to Groundwater Flow Model Conceptual Model Water Budget Numerical Groundwater Model

Potential Proj ects for BCGS A  Drill new, or locate suitable existing wells for groundwater monitoring  S urface water instrumentation and monitoring  Baseline groundwater quality sampling

GS P Development Timeline July 2019 • Begin Draft GSP development July 2020 • Draft GSP available for public review December 2020 • Final Draft GSP submitted to DWR

Open Discussion  Who are the private groundwater users in the S ubbasin?  Rough estimate of volume used  Use of groundwater  Groundwater quality  Concerns?  Who has concerns about the current groundwater conditions or elements of the GS P?  What specific subj ect matter should be discussed in the GS P?
