2 WATER PLANNING COMMITTEE DISCUSSION OUTLINE Date: October 6, 2014 Originator: Ganesh Krishnamurthy / Sudhir Mohleji - Engineering Subject: AMENDMENT TO THE PROFESSIONAL SERVICES AGREEMENT WITH MWH AMERICAS TO COMPLETE TDS OFFSET PLAN FOR DISCHARGES FROM REGIONAL, HORSETHIEF CANYON, RAILROAD CANYON WASTEWATER RECLAMATION FACILITES AND WILDOMAR RECYCLED WATER SYSTEM BACKGROUND AND RECOMMENDATION The total dissolved solids (TDS) concentrations (also referred to as "salinity") in the effluent discharges at the Elsinore Valley Municipal Water District (EVMWD) wastewater reclamation facilities (WRFs) exceed the allowable TDS limits on occasions. According to the wastewater discharge permits, EVWMD is required to submit to the Regional Water Quality Control Board (RWQCB) TDS Offset Plans describing specific steps to offset the excess TDS discharges. In the July 2, 2014, Study Session, a presentation was made to the EVMWD Board on the status of the Salt Nutrient Management Plan (SNMP) for Upper Temescal Valley (UTV) and other TDS Offset Plans submitted to the RWQCB. This presentation included an overview of the historic and projected TDS mass loads to be offset in the EVMWD discharges in the Elsinore and UTV Basins and the proposed actions to be taken. As part of this regulatory required effort, in several previous discussions, the Board has been appraised of the likely future need of desalters that are facilities with processes that remove TDS from the effluent discharges or potable water. Before proceeding with any effort on desalters, such as pilot testing, etc., it is important to identify the most suitable locations, and approximate size of the required facilities that would have the potential to fulfill the goals of required TDS mass to be offset in the respective basins. Determination of most preferred locations is a function of many factors, such as the existing TDS levels and quality of water; the quantity of water required to be desalted to meet the desired

3 TDS mass offset; capital, operation and maintenance costs; site availability, proximity of the proposed facility to the Santa Ana Regional Interceptor (SARI) for brine disposal; etc. On February 9, 2012, the Board authorized a Professional Services Agreement (PSA) with MWH Americas, Inc. to develop a TDS Offset Plan in the amount of $315, and the scope included eleven (11) tasks. The primary focus of the scope was to investigate alternatives for TDS offsets in the Regional WRF discharges to Temescal Creek, but effort was included on the salinity offset in the discharges of the other two WRFs. As this project progressed with continual involvement and input of the RWQCB, the scope of many tasks changed; additional effort/analysis was done on some tasks, while the scope of some tasks was determined to be unnecessary. Before the project investigation could be completed, MWH was put on hold for this project in late To ensure that large expenditures for desalters would be justified, there has been a significant ongoing debate between EVMWD, its consultants, and the RWQCB about the validity of the basins water quality objectives and even to date efforts continue to establish the final objectives for both the UTV and the Elsinore Basins. Current indications, based on partial completion of the SNMP (being developed as a separate contract by Wildermuth Environmental Inc.) for the UTV, are that no TDS Offsets "may" be necessary for the Regional WRF and Horsethief Canyon WRF discharges. However, it will be confirmed after completion of the SNMP and acceptance of the RWQCB. For the Elsinore Basin, the salt offsets will be required for the discharges from Railroad Canyon WRF and Eastern Municipal Water District recycled water supplied to the Canyon Lake Golf Course and Wildomar area. With the District preference to proceed in a timely and proactive manner to complete the TDS offset Plan, staff will request the Board to consider approval of Amendment 1 to the PSA for the TDS Offset Plan. MWH's Amendment 1 scope of work and fee estimate are attached. The key Task (A.1) in the scope includes completion of the TDS Offset Plan for the Elsinore Basin assuming the Basin Water Quality Objective (WQO) will remain 480 mg/l. Task A.2 includes MWH participation in meetings with the RWQCB and presentations to EVMWD Board. An optional Task A.3 has been added to reassess the TDS Offset requirements in case the WQO for the Elsinore Basin is different than 480 mg/l, or the WQO established in future for the UTV requires TDS offsets. MWH will proceed on this optional task only if needed. Table 1 included in the Amendment 1 scope of work presents a detailed (task-by-task) explanation of the status (% completion of scope and budget) of each task of the original plan. The cost of additional work performed on some original tasks was $61,000 and the remaining budget from the original scope is $67,348, resulting in net remaining budget of $6,348. Taking into account the remaining budget, the total cost of Amendment 1 is $87,136 including completion of Optional Tasks, but it will be $40,428 only if the optional tasks would not be required.

4 Staff plans to present this item at the October 23, 2014 Board meeting. This item, including overhead of $4,357, as well as staff time and fringe benefits of $12,663, totals $104,158.

14 WATER PLANNING COMMITTEE DISCUSSION OUTLINE Date: October 6, 2014 Originator: Ganesh Krishnamurthy - Engineering Subject: AMENDMENT TO THE PROFESSIONAL SERVICES AGREEMENT WITH WILDERMUTH ENVIRONMENTAL, INC. FOR DEVELOPMENT OF THE T UPPER TEMESCAL VALLEY SALT NUTRIENT MANAGEMENT NT PLAN BACKGROUND AND RECOMMENDATION Elsinore Valley Municipal Water District (EVMWD) and Eastern Municipal Water District (Eastern) are collaborating as equal partners in the development of a Salt Nutrient Management Plan (SNMP) for the Upper Temescal Valley Ground Water Management Zones (UTVGMZ). The GMZs consist of Warm Springs, Lee Lake and Bedford Management Zones. The Regional Water Quality Control Board (RWQCB) requires that EVMWD and Eastern prepare the SNMP to support the renewal of each agency's waste discharge limitations for total dissolved solids (TDS) and nitrogen (N) for recycled water discharge and/or reuse in the UTVGMZ and to satisfy salt offset requirements for periodic historical violations of the existing waste discharge limitations. The effluent discharge from EVMWD's Regional Water Reclamation Facility (RWRF) has often exceeded the allowable TDS limit of 700 mg/l. During the years 2005 through 2011, the MWH Study (TDS Offset plan for RWRF, September 2011) calculated approximately 446 tons of excess salt discharged, which required the offset. Additional excess salt has also been discharged during the last three years. As per the regulatory requirement, on June 24, 2013 EVMWD submitted an RWRF TDS Offset Plan to the RWQCB, which was approved by the RWQCB on July 23, As part of this Plan, EVMWD committed to develop the UTVGMZ SNMP by January 1, A proposal consisting of four tasks to develop the SNMP was presented by Wildermuth Environmental, Inc. (WEI) on December 6, 2012 and it was revised on May 13, On July 24, 2013, the EVMWD Board approved a Professional Services Agreement with WEI in the amount of $322,964. Via a separate Agreement between EVMWD and

15 Eastern, fifty percent of the SNMP development is being reimbursed by Eastern to EVMWD and the development of the SNMP is in progress. For developing the SNMP, i.e., implementing the RWQCB approved TDS Offset Plan, the RWQCB considered this step as an acceptable TDS offset for all past discharges in excess of the TDS limit until the January 1, 2015 SNMP completion date. This has been a huge benefit to EVMWD, i.e., not having to mitigate several hundred tons of excess salt for developing the SNMP. WEI's original scope of work, which was approved by the RWQCB, acknowledged that a current ambient water quality (AWQ) determination could not be calculated per the standard AWQ methodology and that a finding would not be needed to complete the SNMP. RWQCB staff subsequently determined that a current AWQ determination is needed for the completion and approval of the UTVGMZ SNMP and that a substitute methodology is acceptable for making this determination. The requested amendment is required to implement the additional Task 5: Calculate Substitute Current AWQ for the UTVGMZ. Staff plans to present this item at the October 23, 2014 Board meeting. WEI's proposal dated August 26, 2014 including scope of work, detailed justification for this additional work, fee estimate and schedule is attached. As previously mentioned, fifty percent of the additional requested $67,992 will be reimbursed by Eastern to EVMWD via a separate Agreement between Eastern and EVMWD. This item, including overhead of $3,400, as well as staff time and fringe benefits of $28, totals $100, ENVIRONMENTAL WORK STATUS This item does not constitute a project under CEQA.

17 August 26, 2014 Elsinore Valley Municipal Water District Attention: Ganesh Krishnamurthy Chaney Street PO Box 3000 Lake Elsinore, CA Eastern Municipal Water District Attention: Jayne Joy 2270 Trumble Road P.O. Box 8300 Perris, CA Subject: Request to Amend the Scope of Work and Budget for Work Order No /Purchase Order No Dear Mr. Krishnamurthy and Ms. Joy: The purpose of this letter is to request an amendment to the scope of work and budget for the Professional Services Agreement (Work Order No /Purchase Order No. 4927) between Wildermuth Environmental Inc. (WEI) and the Elsinore Valley Municipal Water District (Elsinore Valley) for the Development of an Upper Temescal Valley Salt and Nutrient Management Plan (UTV SNMP). The requested amendment is required too add and implement Task 5: Calculate Substitute Current Ambient Water Quality for the Upper Temescal Valley. Task 5 has been required by the Santa Ana Regional Water Quality Control Board (Regional Board). The original scope of work, which was approved by the Regionall Board, acknowledged that a current ambient water quality determination could not be calculated per the standard ambient water quality methodology and that a finding would not be needed to complete the SNMP. Regional Board staff subsequently determined that a current ambient water quality determination is needed for the completion and approval of the UTV SNMP and that a substitute methodology is acceptable for making this determination. The estimatedd cost to complete Task 5 is $67,992. A description of the original scope of work; the tasks performed to date; and the scope of work, schedule, and budget to complete Task 5 are provided below.

18 Mr. Krishnamurthy and Ms. Joy August 26, 2014 Request to Amend the Scope of Work and Budget Page 2 of 4 Background Elsinore Valley and the Eastern Municipal Water District (Eastern) are collaborating on the development of the UTV SNMP. The Regional Board has required that Elsinore Valley and Eastern prepare the SNMP to support the renewal of each agency s waste discharge limitations for total dissolved solids (TDS) and nitrogen (N) for recycled water discharge and/or reuse in the UTV and to satisfy salt offset requirements for periodic historical violations of the existing waste discharge limitations. A major barrier to writing permits for recycled water discharges and reuse in the UTV is the lack of antidegradation groundwater objectives for the three UTV groundwater management zones (GMZs): Bedford, Lee Lake, and Warm Springs. The original scope of work to develop the UTV SNMP outlined three main tasks: Task 1 Compute Antidegradation Objectives for N/TDS. The objective of this task is to apply a substitute methodology to calculate the historical ambient TDS and N concentrations for the combined Bedford, Lee Lake, and Warm Springs GMZs, hereafter referred to as the UTVGMZ. Task 1 had the additional objective of recommending a groundwater monitoring program that will allow future ambient water quality calculations to be performed per the ambient water quality methodology used in the rest of the Watershed. Task 2 Estimate the Impact of Recycled Water Reuse and Discharge Plans on the Water Quality of the UTVGMZ. The objective of this task is to collaborate with all interested stakeholders to characterize the range of future recycled water discharge and reuse plans and the resultant impact to future TDS and N concentrations in the UTVGMZ and downstream. Task 3 Describe Regulatory Implications of Recycled Water Planning Alternatives and Develop Upper Temescal Valley SNMP to Address N/TDS Challenges. The objective of this task is to document the plan for managing TDS and N discharges in the UTVGMZ based on the results of Task 2. The original scope of work was developed by WEI in May 2013 and was approved by the Regional Board in July Elsinore Valley and Eastern entered into a professional services agreement and gave WEI notice to proceed in August A kick off meeting was not held until November Between November 2013 and April 2014, WEI executed Task 1, with the exception of the technical memorandum. In May 2014, WEI presented the results of Task 1 to Elsinore Valley and Eastern. In June 2014, after a few refinements, the same presentation was made to Regional Board staff. Subsequent to the June 2014 presentation, the Regional Board requested two follow up actions: 1. Can WEI run the model on the individual MZs (instead of one model for the whole UTV) to see if there should be different objectives for the Warm Springs, Lee Lake, and Bedford GMZs? The management zones were delineated separately in 2000, and the Regional Board wants to be certain that there is a good reason why the Basin Plan should be amended to combine them together as one. 2. Prepare a substitute current ambient water quality determination for TDS/N in the UTV GMZs. This task is required for approval of the UTV SNMP.

19 Mr. Krishnamurthy and Ms. Joy August 26, 2014 Request to Amend the Scope of Work and Budget Page 3 of 4 Addressing these actions requires an amendment to the approved scope of work. Performing the work requested in (1) is not feasible given the lack of data available to support an understanding of the surface water and groundwater interactions at discrete locations along Temescal Creek as it traverses the UTV. Addressing action (2) will improve the overall UTV SNMP work products. WEI corresponded with Elsinore Valley and Eastern to determine how to respond to the Regional Board s requests. Based on this correspondence, it was agreed that addressing action (1) was not feasible and that action (2) should be performed. WEI staff engaged in subsequent correspondence with Regional Board staff throughout July 2014 to refine the scope of work to address the requested actions. The Regional Board reserved the right do disagree with a recommendation for combining the UTV GMZs into one management zone and directed WEI, Elsinore Valley, and Eastern to proceed with the substitute ambient water quality determination. The following is the proposed scope of work to calculate the substitute current ambient TDS and N concentrations for the UTVGMZ. SCOPE OF WORK The substitute calculation of ambient groundwater quality will be performed in a manner similar to that used to calculate the historical ambient groundwater quality. The calculated time history of inflows to and outflows from the UTVGMZ will be input into the constantly stirred reactor model (CSRM) developed in Task 1 to compute 20 year volume weighted TDS and nitrogen concentrations. Available groundwater quality data at wells will be used to calibrate inputs to the model for which assumptions need to be made. The inflow terms include streambed infiltration of stormwater and recycled water discharges and the deep infiltration of applied water. 1 The outflow terms include groundwater production, evapotranspiration, and rising groundwater. Groundwater production is known, and the deep infiltration of applied water can be calculated from land use. As was done in Task 1, the WLAM will be used to estimate streambed infiltration from storm flow and recycled water discharges. The WLAM in the reach from the All American Aggregate Pit to Lake Elsinore was refined and calibrated for the historical period as part of Task 1. The WLAM will need to be recalibrated for the new period as the hydrologic stresses have significantly changed. These changes include land use and the discharge of recycled water to the wash. The stream gage available for calibration is downstream of the gage that was available for the work that was completed in Task 1. The change in gage location will require expanding the drainage area of the model. WEI has already developed the drainage areas downstream of the UTVMZ and the Main Street gage as part of the WLAM used by the Basin Monitoring Program Task Force. The precipitation data for the expanded portion of the model will need to be developed to calibrate the model. It is anticipated that the results of current ambient analysis may change our recommendation for setting the antidegradation objective. Thus, the results of Task 5 will be documented together with the Task 1 memorandum, which will contain the recommendation to the Regional Board for setting the antidegradation objective. Finally, the UTV groundwater and surface water monitoring plan drafted for Task 1 needs to be refined such that this process can be replicated every three years or until ambient water quality can be calculated per the standard methodology. 1 As was done for the calculation of historical ambient water quality in Task 1, the deep infiltration of precipitation is assumed to be negligible.

20 Mr. Krishnamurthy and Ms. Joy August 26, 2014 Request to Amend the Scope of Work and Budget Page 4 of 4 The major subtasks are: Task 5.1 Update and calibrate the WLAM calibration from the Main Street gage in Corona to Lake Elsinore to estimate annual streambed infiltration of stormwater and recycled water for the July 1, 1990 through June 30, 3014 period. Task 5.2 Calculate current ambient water quality using the CSRM methodology developed in Task 1. Task 5.3 Revise the monitoring plan developed in Task 1.14 so that the substitute methodology can be performed in the future Task 5.4 Prepare draft and final reports (to be incorporated with the Task 1 Report) BUDGET AND SCHEDULE The total estimated cost to perform Task 5 is $67,992. The breakdown by subtask is shown in Table 1. Task 5.1 can be completed within three weeks from a notice to proceed. If the notice to proceed is given by September 8, 2014, Task 5.1 will be completed by September 26, Task 5.2 can be completed in one week from completion of Task 5.1. If the notice to proceed is given by September 8, 2014, Task 5.2 will be completed by October 3, Task 5.3 can be completed in five weeks from completion of Task 5.2. The draft technical memorandum will be completed within three weeks of completion of Task 5.2 and the final within five weeks. If the notice to proceed is given by September 8, 2014, Task 5.2 will be completed by November 7, Task 2 of the original scope of work, the stakeholder process, can begin anytime. Task 3 can start as soon as Task 5.3 is completed. Completion of the draft SNMP Report is still anticipated by January 31, We are ready to implement Task 5 immediately upon notice to proceed.

27 WATER PLANNING COMMITTEE DISCUSSION OUTLINE Date: October 6, 2014 Originator: Jesús R Gastélum Water Resources Subject: OVERVIEW OF NEW CALIFORNIA GROUNDWATER MANAGEMENT LAW BACKGROUND AND RECOMMENDATION On September 16, Governor Jerry Brown signed the California State s Groundwater Bills (AB 1739, SB 1168, and SB1319), which are aiming to improve sustainability of groundwater resources in the State. Given its relevant role as monitoring agency and water user, Elsinore Valley Municipal Water District (EVMWD) is expected to play a key role during the process of instrumentation of the cited bills, which will require the creation of Groundwater Sustainability Agencies (GSAs) and implementation of groundwater management plans for the Elsinore Valley Groundwater Basin (EVGB) and neighboring groundwater basins. During the meeting, staff will provide with a summary of the bill, and will discuss implications and next steps for EVMWD. ENVIRONMENTAL WORK STATUS Not applicable FISCAL IMPACT Within Budget - Not applicable Attachments: Elsinore Memorandum Regarding Groundwater Legislation Summary of Sustainable Groundwater Management California Groundwater Legislation Timeline

28 Memorandum To: Elsinore Valley Municipal Water District File No.: From: Best Best & Krieger Date: September 16, 2014 Re: Key Components of Groundwater Legislation Key Components of California Groundwater Legislation Although California enacted a statewide surface water law in 1914 requiring the permitting of nearly all surface water uses, the state has never broadly regulated groundwater. Until this year, it seemed unlikely that California groundwater would be regulated in the foreseeable future, but with three widely-supported bills having materialized over the last several months, the regulation of California s groundwater is now imminent. The Legislature recently passed Senate Bill 1168, Senate Bill 1319 (both Pavley, D- Agoura Hills), and Assembly Bill 1739 (Dickinson, D-Sacramento), which were written to be adopted together and to work in concert with one another. The Governor signed the legislation on September 16, 2014, which establishes the Sustainable Groundwater Management Act (Act) and provides for the new regulation of California s groundwater, in a once-in-a-century event. The Act states that groundwater is a critical natural resource for the state and the state s basins must be sustainably managed. Sustainable groundwater management means that groundwater must be used in a way that does not cause undesirable results, such as the chronic lowering of water levels, reduction in storage capacity, seawater intrusion, degraded water quality, land subsidence, and surface water depletions. The Act also states that sustainable management best occurs at the local level but provides authority for state management when local agencies are unwilling or unable to effect sustainable management. Application The following is a summary and analysis of the key components of the Act. The Act will primarily affect high and medium priority 1 basins as defined 2 and designated by the Department of Water Resources (DWR). 1 DWR must designate all basins as high, medium, low, or very low priority by January 31, If priorities are subsequently amended, newly designated high and medium priority basins will have two years to form a groundwater sustainability agency and five years to adopt a groundwater sustainability plan \

29 The Act applies to Indian tribes and the federal government, to the extent authorized under federal law. But the Act specifically notes that federal reserved rights to groundwater are to be respected in full. Low and very low priority basins are exempt from the requirements of the Act but are encouraged to use the Act for basin management guidance. Adjudicated basins or other areas complying with an adjudication of water rights are exempt from the Act except for certain reporting requirements. The Act will not alter surface water or groundwater rights or give local agencies the authority to make binding determinations on water rights. Formation of Groundwater Sustainability Agencies The Act authorizes local agencies, including water corporations regulated by the Public Utilities Commission, to form groundwater sustainability agencies after a public hearing. Local agencies must inform DWR of the formation of these agencies. Multiple local agencies can form a single groundwater sustainability agency through a formal legal agreement. There can be more than one groundwater sustainability agency per basin, but the agencies must formally coordinate their planning. The entire basin must be covered by a groundwater sustainability agency, i.e., there can be no dead zones or unmanaged areas. Groundwater sustainability agencies must provide annual groundwater reports to DWR that include elevation data, extraction data, surface water availability for groundwater recharge or in-lieu use, total water use, and changes in groundwater storage. Counties are presumed the default agency in unmanaged areas and must notify DWR whether they accept or decline that role. Groundwater sustainability agencies must: o Consider the interests of all beneficial uses and users of groundwater and those responsible for implementing groundwater sustainability plans. o Establish and maintain a list of persons interested in receiving notices regarding plan preparation, meeting announcements, and availability of draft plans, maps, and other relevant documents. The Act requires that all high and medium priority basins be governed by these agencies by June 30, Adoption of Groundwater Sustainability Plans Groundwater sustainability agencies are authorized to develop and adopt groundwater sustainability plans. 2 Basins mean basins and subbasins identified in DWR s California s Groundwater: Bulletin 118. The Act provides that a local agency may request DWR to change basin boundaries upon a sufficient technical showing that such a change is justified \

30 Before developing a groundwater sustainability plan, the agency must release a written statement that describes how interested parties may participate. Plans must meet the sustainability goals of the Act. Plans can take the following forms: o Single plan by one agency, o Single plan by multiple agencies, or o Multiple plans by multiple agencies. 3 All high and medium priority basins must be governed by an adopted groundwater sustainability plan by January 31, 2022 or by January 31, 2020 for basins subject to critical conditions of overdraft. Contents of Groundwater Sustainability Plans A groundwater sustainability plan must include: o Long-term planning, objectives, and goals to achieve basin sustainability within 20 years; o Technical information regarding the basin; o Components relating to the monitoring and management of groundwater levels, groundwater quality degradation, inelastic land surface subsidence, and changes in surface flow and surface water quality that directly affect groundwater levels or quality or are caused by groundwater extraction in the basin; o Mitigation of overdraft; o Recharge areas and basin replenishment. A groundwater sustainability plan shall include basin-specific measures if applicable such as: o Control of saline water intrusion; o Activities implementing, opportunities for, and impediments to, conjunctive use; o Well construction and destruction policies; o Measures addressing groundwater contamination cleanup, recharge, diversions to storage, conservation, water recycling, conveyance, and extraction projects; o Efforts to develop relationships with state and federal regulatory agencies; o Effects on groundwater dependent ecosystems. DWR Review of Groundwater Sustainability Plans DWR must adopt regulations for the evaluation of groundwater sustainability plans, implementation of plans, coordination of agencies, and alternative plans by June 1, DWR will identify necessary plan components to assist local agencies in developing the plans. 3 Multiple agencies with multiple plans in one basin must coordinate with each other to ensure the plans use the same data and methodologies for certain assumptions in developing the plan including groundwater elevation and extraction data, surface water supply, total water use, change in storage, water budget, and sustainable yield \

31 After it adopts a plan, a groundwater sustainability agency shall submit its plan to DWR for review. DWR will post the plan (or plans) on its website and provide 60 days for public comment. DWR must evaluate and issue an assessment of the plan within two years of submission and may include corrective actions to any perceived deficiencies in the plan. Alternatives to Groundwater Sustainability Plans Local agencies may use an alternative instead of a groundwater sustainability plan if it is: o A groundwater management plan, or if it is adopted pursuant to another law authorizing groundwater management, o Management pursuant to an adjudicated action, or o A professional analysis of basin conditions that shows the basin has operated within sustainable yield for the past 10 years. Local agencies must submit the alternative plan to DWR by January 1, 2017 and every five years thereafter. Alternative plans must satisfy the objectives of the Act and are subject to DWR evaluation and assessment. The State Water Resources Control Board (SWRCB) may also impose yearly groundwater reporting requirements on local agencies. Powers of Groundwater Sustainability Agencies Groundwater sustainability agencies that adopt groundwater sustainability plans will have new powers and authorities and may do anything necessary or proper to carry out the purposes of the Act, including authorities to: o Adopt rules, regulations, ordinances, and resolutions; o Propose, update, and impose fees, and levy groundwater charges; o Require registration of and impose requirements on wells and other groundwater extraction facilities; o Require measurements of well levels in every well; o Acquire, enjoy, and dispose of real and personal property, including water rights; o Transport, reclaim, purify, desalinate, treat, or otherwise manage and control polluted water, wastewater, or other waters for subsequent use; o File an action to determine the validity of the groundwater sustainability plan; o Control groundwater extractions by regulating, limiting, and suspending extractions from individual groundwater wells or wells in the aggregate; o Authorize transfers of groundwater extraction within agency boundaries. The Act does not allow groundwater sustainability agencies to issue permits for the construction, modification, or abandonment of groundwater wells. But a county may \

32 authorize a groundwater sustainability agency to issue permits for the construction, modification, or abandonment of groundwater wells. Enforcement powers including the ability to impose civil penalties and bring superior court actions. Coordinate Land Use Planning and Water Use Planning Planning agencies must give wide notice of their intent to adopt or substantially amend a city or county s general plan, including to those managing groundwater. Public water systems and groundwater sustainability agencies must then provide planning agencies with relevant water supply and planning information. Before planning agencies can adopt or substantially amend a general plan, they must consider the adoption of groundwater sustainability plans, adjudications of water rights, and any SWRCB orders or plans. State Intervention Intervention is not mandatory; SWRCB always may exercise discretion. Drought will not necessitate state intervention. If any of the following conditions apply, SWRCB may designate a basin as a probationary basin: If after June 30, 2017 none of the following have occurred: o A local agency has elected to be a groundwater sustainability agency; o A collection of local agencies has formed a groundwater sustainability agency or prepared agreements to develop one or more groundwater sustainability plans that will collectively serve as a groundwater sustainability plan for the entire basin; or o A local agency has submitted an alternative plan that has been approved or is pending approval. If after January 31, 2020 none of the following have occurred in a basin subject to critical overdraft: o A groundwater sustainability agency has adopted a groundwater sustainability plan for the entire basin; o A collection of local agencies have adopted groundwater sustainability plans that serve the entire basin; or o DWR has approved an alternative plan. If after January 31, 2020: o DWR in consultation with SWRCB has determined that a groundwater sustainability plan for a basin subject to critical overdraft is inadequate or that the groundwater sustainability program is not being implemented in a way to achieve the sustainability goal. If after January 31, 2022 none of the following have occurred in a high or medium priority basin not subject to critical overdraft: \

33 o A groundwater sustainability agency has adopted a groundwater sustainability plan for the entire basin; o A collection of local agencies has adopted groundwater sustainability plans that serve the entire basin; or o DWR has approved an alternative plan. If after January 31, 2022 both of the following have occurred in a basin not subject to critical overdraft: o DWR in consultation with SWRCB has determined that a groundwater sustainability plan is inadequate or that the groundwater sustainability program is not being implemented in a way to achieve the sustainability goal. o SWRCB determines that the basin is in a condition of long-term overdraft. If after January 31, 2025, both of the following have occurred in a basin not subject to critical overdraft: o DWR in consultation with SWRCB has determined that a groundwater sustainability plan is inadequate or that the groundwater sustainability plan is not being implemented in a way to achieve the sustainability goal. o SWRCB determines that the basin is in a condition where groundwater extractions significantly deplete interconnected surface waters. SWRCB must exclude from probationary status any part of a basin that a groundwater sustainability agency demonstrates complies with the sustainability goal. Designation as a probationary basin triggers a 180-day cure period. During the cure period, SWRCB may appoint a mediator to assist local agencies. SWRCB may require extractors to report extractions. If the local agency does not cure the deficiency, SWRCB may proceed with an interim plan: o The interim plan would include: Identification of the actions that are necessary to correct a condition of long-term overdraft or a condition where groundwater extractions result in significant depletions of interconnected surface waters, including recommendations for appropriate action; A time schedule for the actions to be taken; A description of the monitoring to be taken; An interim plan may include: restrictions on groundwater extraction, a physical solution, or principles and guidelines for the administration of rights to surface waters that are connected to the basin; An interim plan must include any element of a groundwater sustainability plan that SWRCB finds complies or would help with the sustainability goal of the basin and may implement or rely on parts of an adjudication action. SWRCB may impose fees on extractors to pay its costs. There are various escape hatches for SWRCB to rescind an interim plan and return to local management when local agencies demonstrate that they are making progress toward sustainable basin management \

34 CEQA Implications The preparation and adoption of groundwater sustainability plans is exempt from CEQA. The Act does not exempt plan-related projects that would significantly affect water supplies for fish and wildlife. Elsinore Valley Municipal Water District-Specific Implications EVMWD s current groundwater sources are from the Elsinore Basin, Coldwater Basin, Lee Lake Basin, and Bedford Basin. Coldwater Basin, Lee Lake Basin, and Bedford Basins are not DWR-designated basins or subbasins that are subject to the Act but are considered part of the Elsinore Basin. The Act provides guidelines to petition DWR to revise basin boundaries and designate new subbasins. EVMWD should consider whether it wants to petition DWR to designate Coldwater, Lee Lake, and Bedford as subbasins because it might assist with basin management activities. o For example, any local agency with water management or land use authority can seek to manage basins within its jurisdiction. o Thus, EVMWD might have to coordinate its management activities with the City of Corona, Lee Lake Water District, the county, and other interested parties. o Revised basin boundaries might assist with those required coordinated efforts. Elsinore Basin is currently designated by DWR as a high priority basin and is subject to the requirements of the Act. Because EVMWD is the primary, if not exclusive, public agency pumper from the Elsinore Basin, EVMWD is likely in the best position to be the Groundwater Sustainability Agency for the main Elsinore Basin. One or more Groundwater Sustainability Agency must cover the entire basin by June 30, o Groundwater Sustainability Agency options are as follows: One local agency elects to be one GSA that covers the whole basin; Multiple local agencies form one GSA that covers the whole basin; or Multiple local agencies form multiple GSAs that cover the whole basin. If DWR designates the basin as one subject to critical conditions of overdraft, a Groundwater Sustainability Plan must be adopted by January 31, If it is not sodesignated, its plan must be adopted by January 31, EVMWD should decide whether it will be a Groundwater Sustainability Agency on its own or whether to form one with other interested local agencies, such as the City of Elsinore, Lee Lake Water District, the City of Corona, Western Municipal Water District, and the county, through a joint powers agreement. EVMWD may wish to consider being the Groundwater Sustainability Agency for the main Elsinore Basin, but share that responsibility in one or more of the sub-basins \

35 If EVMWD decides to be its own Groundwater Sustainability Agency, it should begin coordinating with other local agencies to ensure that any Groundwater Sustainability Plan it develops correlates with other plans in the basin. If EVMWD decides to be or form a Groundwater Sustainability Agency, it must determine whether to develop and adopt a Groundwater Sustainability Plan or alternative plan. Both will be subject to DWR approval. EVMWD should wait to finalize a Groundwater Sustainability Plan, or any alternative, until DWR provides more guidance regarding the evaluation and implementation of Groundwater Sustainability Plans, which must occur by June 1, According to its Urban Water Management Plan, EVMWD also has rights in the following adjudicated basins: San Bernardino Bunker Hill, Rialto-Colton, and Riverside North but is not currently using these rights because EVMWD does not have the infrastructure available to deliver the water from these sources. The Act specifically exempts the San Bernardino Basin area, the Rialto-Colton Basin, and the Riverside Basin from most of the requirements of the Act because they are adjudicated. However the Act imposes certain reporting requirements on the Watermaster or local agencies within adjudicated basins. Specifically they must do all of the following: o By April 1, 2016, submit to DWR a copy of the final judgment or judicial order, and any amendments thereto, which finally adjudicates the basin; o Submit any post-april 2016 amendments to the final judgment to DWR within 90 days of entry by a court; and o By April 1, 2016 and annually thereafter, submit to DWR a report with the following information: Groundwater elevation data; Aggregated groundwater extraction data for the preceding water year; Surface water used for or available for use for groundwater recharge or in-lieu use; Total water use; Change in groundwater storage; Annual report submitted to court. The Watermasters for the adjudicated basins are thus required to submit this information to DWR. o EVMWD should communicate with the agencies that will be responsible for reporting on the Basins to confirm their recognition of EVMWD s rights and to offer any assistance that may be needed from EVMWD \

36 Summary of Sustainable Groundwater Management Act The recently approved California State s Groundwater Bills (AB 1739, SB 1168, and SB1319) are aiming to improve sustainability of groundwater resources. Given its relevant role as monitoring agency and water user, EVMWD is expected to play a key role during the process of instrumentation of the cited bills, which will require the creation of Groundwater Sustainability Agencies (GSAs) and implementation of groundwater management plans for the EVGB and neighboring groundwater basins. Bill Highlights and Requirements: The Act does not apply to adjudicated basins or low priority basins as defined by Department of Water Resources Creation of Groundwater Sustainability Agencies: These agencies are required to be formed by June 30, These agencies will be in charge of establishing and accomplishing the long term (50 year horizon) sustainable groundwater management goals. The agencies will be authorized to limit or curtail groundwater production, monitor water production, track location of wells, and assess regulatory fees. The framework and guidelines to create these agencies is not very well defined Adoption of Groundwater Sustainability Plan. The plan must be done within 5-7 years (January 1, 2020 for basin with critical overdraft conditions, or Jan 1, 2022 for the rest of the medium or high priority basins). The plan will include goals to eliminate undesirable groundwater conditions such as groundwater depletions by The plan will incorporate monitoring and management of the basins for long term horizon (50 years). State Intervention: The Act authorizes the State Water Resources Control Board (SWRCB) to intervene under the following conditions: local agencies fail to elect or form a groundwater sustainability agency, or to implement of groundwater sustainability plan; when it is determined that the plan is inadequate to achieve groundwater sustainability or when it is determined that the basins has long term overdraft or groundwater is causing significant depletions of interconnected surface water.

37 Next steps and challenges: Get in communication and/or wait for guidelines from SWRCB/DWR as to the specific process to follow for the creation of GSA Internally, evaluate whether only a GSA could be implemented to manage our local groundwater basins (Elsinore, Warm Springs, Lee Lake, Coldwater, and Bedford), or to consider a couple of them based on the vested interest of other stakeholders (City of Corona, Lee Lake Water District) Evaluating degree of investment of time and resources, which will be required to implement the requested regulations, and accomplishment of the groundwater sustainability goals
