Description 1.1 Overview This document presents the 2025 Urban Water Management Plan (UWMP or Plan) for the South Tahoe Public Utility District (District) service area, which includes most of the City of South Lake Tahoe and portions of unincorporated El Dorado County. This chapter describes the general purpose of the UWMP. A list of acronyms and abbreviations is provided at the end of the table of contents. 1.2 Purpose An UWMP is a planning tool that generally guides the actions of water management agencies. It provides managers and the public with a broad perspective on water supply issues. It is not a substitute for project-specific planning documents, nor was it intended to be when mandated by the State Legislature. For example, the Legislature mandated that a plan includes a section which “describes the opportunities for exchanges or water transfers on a short-term or long-term basis.” (California Urban Water Management Planning Act, Article 2, Section 10630(d).) The identification of such opportunities, and the inclusion of those opportunities in a general water service reliability analysis, neither commits a water management agency to pursue a particular water exchange/transfer opportunity, nor precludes a water management agency from exploring exchange/transfer opportunities not identified in the plan. When specific projects are chosen to be implemented, detailed project plans are developed, environmental analysis, if required, is prepared, and financial and operational plans are detailed. In short, this Plan is a management tool, providing a framework for action, but not functioning as a detailed project development or action. It is important that this Plan be viewed as a long-term, general planning document, rather than as an exact blueprint for supply and demand management. Water management in California is not a matter of certainty, and planning projections may change in response to a number of factors. From this perspective, it is appropriate to look at the Plan as a general planning framework, not a specific action plan. It is an effort to generally answer a series of planning questions including: What are the potential sources of supply and what is their reasonable probable yield? What is the probable demand, given a reasonable set of assumptions about growth and implementation of good water management practices? How well do supply and demand figures match up, assuming that the various probable supplies will be pursued by the implementing agency? Using these “framework” questions and resulting answers, the implementing agency will pursue feasible and cost-effective options and opportunities to meet demands. The California Urban Water Management Planning Act (Act) became part of the California Water Code with the passage of Assembly Bill (AB) 797 during the 1983-1984 regular session of the California Legislature. The Act requires that every urban water supplier providing water DRAFT 2025 Urban Water Management Plan, Page 1-2 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 uwmp_draft 04.29.2026.docx for municipal purposes, either directly or indirectly, to more than 3,000 customers, or supplying more than 3,000 acre-feet (AF) of water annually, to prepare a plan that: Accomplishes water supply planning over a 20-year period in 5-year increments (the District is going beyond the requirements of the Act by developing a plan which spans 25 years). Identifies and quantifies adequate water supplies, including recycled water, for existing and future demands, in normal, single-dry, and multiple-dry years. Implements conservation and efficient use of urban water supplies. State legislation, Senate Bill 7 of Special Extended Session 7 (SBX7-7) was signed into law in November 2009, which calls for progress towards a 20 percent reduction in per capita water use statewide by 2020. The legislation, known as 20x2020 mandated each urban retail supplier develop and report an interim 2015 water use target, their baseline daily per capita use and 2020 compliance daily per capita use, along with the basis for determining those estimates. This UWMP reports on the District’s continued compliance with meeting the SBX7-7 targets since 2020 in Section 5.2. State legislation, Making Water Conservation a California Way of Life (Assembly Bill 1668 and Senate Bill 606) concluded rulemaking in July 3, 2024. For simplicity, the Making Water Conservation a California Way of Life regulation is hereafter referred to as the California Water Use Objective (CWUO). The CWUO framework establishes individual efficiency goals for each urban retail water supplier based on unique characteristics of the supplier’s service area. The intent is to reduce urban water use and adapt to climate change. In some instances, suppliers may adjust their objective to account for direct potable reuse, seasonal tourism, and emergency response. Starting in 2027 suppliers need to meet the overall objective. The CWUO regulation also has provisions requiring water suppliers to undertake Commercial, Industrial and Institutional (CII) performance measures. The District is subject to CWUO. In short, the Plan answers the question: Will there be enough water for the area served by the District in future years, and what mix of programs should be explored for making this water available? The analysis in this Plan documents that the District has the necessary existing and projected water supplies to meet normal and dry-year demands. The primary requirements for the UWMP include: A description of the water service area. A description of the existing and planned water supply sources. Estimates of past, present, and projected water use. SBX7-7 (20x2020) analysis and target compliance. An assessment of water supply reliability. A description of the conservation program and demand management measures. DRAFT 2025 Urban Water Management Plan, Page 1-3 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 uwmp_draft 04.29.2026.docx A description of plan adoption, submittal, and implementation. The 2025 UWMP must submit data in specific tables to the California Department of Water Resources (DWR), which has provided these tables, and this UWMP utilizes the provided tables without changes to format or organization. The District 2025 UWMP presents each required element per the DWR 2025 Urban Water Management Plan Guidelines. This UWMP is organized to follow the DWR 2025 UWMP Guidelines recommended organization and data tables. Appendix A contains the DWR Checklist providing the location of the content that meets the UWMP legislative requirements. During assessment of the District’s 2014 Groundwater Management Plan (2014 GWMP), DWR recommended that differing water demand projections used in the 2014 GWMP and the UWMP be reconciled (DWR, 2019). DWR also recommended that the reconciled water demand projections be incorporated into the projected water budgets used in each document. In order to satisfy this recommendation, both the updated 2014 GWMP and the 2025 UWMP use the same population growth rate (California Department of Finance El Dorado County 50-year population growth rate) as a basis for projecting future water demands. In addition, projected total supplies and supply/shortfall estimates provided in this UWMP are calculated using the same storage threshold developed for the updated 2014 GWMP, which was carried forward to the Alternate Groundwater Sustainability Plan (Alternate GSP) that was submitted in 2016, approved by DWR. The storage threshold represents the total amount of groundwater available for groundwater extraction in the Tahoe South Subbasin (TSS), without any undesirable results to all beneficial users and uses of groundwater within the TSS. However, as differences in the Alternate GSP and UWMP reporting requirements (calendar year [CY] versus water year [WY]) do occur, there is not a direct comparison between the projected future water demands presented in the 2025 UWMP with the projected water demands to be presented in the Alternate GSP.

The District does not receive supply from wholesale sources. 2.1 Coordination and Outreach The Tahoe Regional Planning Agency (TRPA) is a two-state regional environmental planning agency tasked with planning efforts in the Tahoe Basin. The District regularly participates in the TRPA water, wastewater, and environmental planning efforts. The District notified TRPA, City of South Lake Tahoe, El Dorado County, and the El Dorado County Water Agency of the UWMP preparation and contacted each respective agency as necessary to develop the UWMP. Agency and public outreach efforts are presented in Section 10 per the UWMP Guideline requirements. DRAFT 2025 Urban Water Management Plan, Page 3-1 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 uwmp_draft 04.29.2026.docx Section 3: System Description The District is a California public utility district that was established in 1950. The District provides water and sewer service throughout the South Lake Tahoe area. The District is the largest water purveyor in the Lake Tahoe Basin. The District maintains a total of 13 wells, with water supply currently provided by 11 active supply wells and two standby wells. In addition to the supply wells, the District, as a monitoring entity, maintains thirty (30) observation wells for groundwater level monitoring under the California Statewide Groundwater Elevation Monitoring (CASGEM) program. The storage and distribution system is comprised of 16 booster pump stations, 20 storage tanks, 21 pressure regulating stations, and 251 miles of potable water pipe. Due to the topography of the District’s service area, the overall distribution system is separated into 30 pressure zones. 3.1 Service Area Description The District’s service area encompasses 27,000 acres in eastern El Dorado County on the southern shore of Lake Tahoe. The service area extends west to include Emerald Bay, east to the California Nevada State Line, and south to include Christmas Valley. The service area includes most, but not all, of the City of South Lake Tahoe and portions of unincorporated El Dorado County. Figure 3-1 illustrates the District boundaries. The District provides water supply within the incorporated City of South Lake Tahoe and the unincorporated communities of Montgomery Estates, Tahoe Paradise, Meyers, Angora Highlands, Fallen Leaf Lake, and Christmas Valley. Lukins Brothers Water Company, Lakeside Water Company, and Tahoe Keys Water Company are small private water providers within or adjacent to the District’s service area. These private water companies are mostly built out and serve approximately 3,000 connections total. The service area has a unique customer base. The area is a tourist destination with extensive lodging facilities and vacation homes. Correspondingly, land use within the service area is primarily residential, with some mixed-use, recreation, and tourist areas, as well as a small portion set aside for conservation. The seasonal fluctuations in the tourist season also affect the seasonal nature of the workforce. These demographics affect the District’s water demands resulting in seasonal and weekly variations much different than a typical California city. All land in the Lake Tahoe region, including the City and the District’s service area, falls under the jurisdiction of the TRPA as defined in the Tahoe Regional Planning Compact (Compact). The Compact requires that all local jurisdiction planning be consistent with a series of Environmental Thresholds. The TRPA Environmental Thresholds effectively provide a growth control mechanism for the region, which in turn impacts projected water demands.

Some precipitation occurs during the other seasons in the form of rain. The monthly temperature ranges from an average low of 34 degrees to an average high of 54 degrees Fahrenheit (2020 District UWMP). The historical annual average precipitation is 34.2 inches, DRAFT 2025 Urban Water Management Plan, Page 3-3 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 uwmp_draft 04.29.2026.docx and the historical average annual evapotranspiration rate (ETo) is 60.6 inches (California DWR CIMIS Reference Evapotranspiration Zones Map). As described in the District’s 2019 Climate Action Plan for the Capital Improvement Program, climate change projections include increased temperature, with a 2.1-2.5ºF increase by 2035, changes in precipitation, decreased snowpack, increased climatic water deficit, changes in flooding and runoff, increase in wildfires, and increased kinetic energy of raindrops (Kennedy/Jenks Consultants, Inc., 2019). 3.2 Population The District service area boundary does not match up exactly with census tract or block group zones. The 2025 UWMP methodology for projecting the District’s future water service area populations will align with the methodology used in Technical Memorandum 1 – Existing System Summary and Demands (TM1). As discussed in Section 4.1, the methodology for projecting the District’s future water demands included projecting their population to account for future growth. The population projections in TM1 assumed a growth rate of 0.46% per year. The District’s 2025 water service area population was calculated using populations in City of South Lake Tahoe and unincorporated areas of El Dorado County. The corresponding yearly percent change based on the Department of Finance’s (DOF) growth rates for El Dorado County as a proxy for the entire service area were then used to calculate the final 2025 population. The 2025 UWMP utilized the District’s 2025 water service area population and a 0.46% population growth rate to project the District’s population out to 2050. Resulting population projections are presented in Table 3-1. The District is using the calculated 2025 population to demonstrate continued compliance with the 20x2020 demand reduction goals in this UWMP and demand management compliance reporting, as needed. The District acknowledges the population served is larger than the permanent resident population. However, as demand reduction compliance is based on relative reductions over time, the District anticipates no significant differences in compliance requirements. The District will continue to track this issue and modify its served population estimates in the future if necessary.

The District serves a wide range of customer types, from small older lots with little landscape to newer larger residences with extensive landscaping and a large resort area with snowmaking. 4.1 Current and Projected Water Demands Projected water demands were calculated in a water demand study by Carollo. They were projected by applying the DOF 50-year population projection growth rate for El Dorado County of 0.46% to the average day demand (ADD) multiplied by the average percentage attributed to each customer class from the 2022 and 2024 water consumption data. As of 2025, the District has 97 unmetered customers and has plans to install meters for the remaining unmetered customers in 2026. Since 2009 when the District initiated metering, water usage per account has decreased almost 43% from 0.498 AFY per account in 2009 when 6% of the accounts were metered to 0.285 AFY per account in 2025 when 100% of the accounts were metered. Reduced demand per account can be attributed both to conservation and increased precipitation, especially in recent years. Metering has been an effective means of conservation; these savings are likely a function of the metering and the ability for District staff to be able to communicate directly to customers regarding water use and leaks, as well as provide education and resources to increase water conservation. Since the projections are based on the ADD multiplied by the average percentage attributed to each customer class from the 2022 and 2024 water consumption data, which incorporates these savings achieved since 2009, the projections include the effects of water conservation into the future. Actual 2025 water demands per category are presented in Table 4-1. As the tables indicate, the majority of the District’s customers are residential. The District commercial category includes office and retail, as well as the resort accounts including hotels, restaurants, and snowmaking. “Losses” account for unbilled water use such as firefighting, flushing, leaks, water theft, or meter inaccuracies characterized as “real losses” in the DWR/AWWA Water audit. As seen in Appendix B, water losses in the District’s system have been trending downwards over the previous 5 years. This reduction in water loss can be correlated with the installation of customer water meters beginning in 1993 and the District’s leak detection program that utilizes aerial imagery to detect chlorine from chlorinated water leaking from the distribution system. Projected customer water demands through 2050 are summarized in Table 4-2. There are no recycled water demands as discussed in Section 6. Water loss for 2020-2024 was calculated per the DWR/American Water Works Association (AWWA) water audit methodology and provided in Appendix B. The water loss audit reporting for 2020-2024 is summarized in Table 4-3. Water Code Section 10608.34 requires compliance with a water loss standard. The State Water Resources Control Board Water Loss Performance Standard is composed of the real water loss standard and the apparent water loss standard, and this standard must be met by 2028. Pursuant to Water Code Section 10631(d)(3)(C), Retail Suppliers are required to include data in their 2025 UWMPs demonstrating whether they met the 2028 water loss standard.

Based on the calculated 2024 water loss, the District meets its Real Water Loss Performance Standard but currently exceeds its Apparent Water Loss Performance Standard. The District must be in compliance with both water loss standards by January 1, 2028. Compliance will be reevaluated with the District’s future annual water loss audits.

These affordable housing units are assumed to be multi-family units. Using the multi-family unit water demand of 0.62 AFY per connection1, the estimated low-income household water demand is 96.1 AFY. These demands are embedded in the projected demands presented throughout this UWMP. The required information for factors to include in water use projections is presented in Table 4-5. Table 4-5: Retail Only: Inclusion in Water Use Projections (DWR Table 4-3) Water Code Section 10631 (a), 10631 (d)(4)(A), and 10631 (d)(4)(B) Are Future Water Savings Included in Projections?

Section 4.1 Are Lower Income Residential Demands Included In Projections? Yes 4.3 Climate Change Considerations Increased temperatures and drought may warrant additional water conservation efforts, especially for outdoor irrigation which can increase in multiple dry years, unless efforts are made to reduce water use. Indoor water conservation efforts, however, can lead to complications and changes in wastewater treatment operations from high strength raw wastewater, damage to systems, and increased cost. Lower wastewater flows also reduce the volume of water available for agricultural irrigation applications of recycled water outside of the District service area. 1 From the analysis completed in 2020 documented in the Technical Memorandum: Total District Water Production Requirements within the Boundaries of the Public Utility Districts Located in the California Portion of the Lake Tahoe Basin (Kennedy/Jenks Consultants, Inc., 2020) DRAFT 2025 Urban Water Management Plan, Page 5-1 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 uwmp_draft 04.29.2026.docx Section 5: Baseline and Targets State law requires that urban water agencies demonstrate a 20 percent reduction in per capita water use by 2020, from the baseline period. DWR has incorporated these requirements into the UWMP requirements. The required demand reduction is based on an agency’s gallons per capita per day (gpcd). Specific methodologies for estimation and analysis of population and demands to determine gpcd targets are provided in the 2025 UWMP Guidebook and Appendices. 5.1 2020 Baseline Demand and Target The DWR UWMP Guidebook methodologies for calculating baseline and reduction targets were used to update the baseline and targets for the 2015 UWMP as described in Section 5.2. The District was not required to update its baseline and targets for 2020 UWMP and 2025 UWMP. 5.2 SB X7-7 Tables and Methodology The 20x2020 process requires that a baseline demand be calculated from which target water demands are determined. The baseline demand is taken as the 10-year average gpcd, ending no earlier than 2004. The baseline demand calculation is based on total supply into the system and estimated service population for each year. The 2020 goal must be no more than 95 percent of a 5-year gpcd average ending no earlier than 2007. Target Method 1, 20 percent of the baseline value, is the selected target. Resulting targets and compliance are summarized in Tables 5-1 and 5-2 of the District’s 2015 and 2020 UWMP. 5.3 Compliance Water Use Targets The District’s 2020 Compliance Water Use Target for the District is 181 gpcd as determined for the 2015 UWMP. The actual 2020 water use was 173 gpcd and was determined using methodologies for estimation and analysis of population and demands. The actual 2020 water use was below the 2020 Compliance Water Use Target; therefore, no additional assessment of present and proposed future measures, programs, or policies have been considered to achieve further water use reductions. The District is not a wholesale supplier. 5.4 Achievement of Target As shown in Table 5-1, the District met their 2020 Compliance Water Use Target in 2020. The District will continue to monitor water use and utilize water use reduction methods to maintain this baseline reduction in future water years.

The District does hold some California State Water Resources Control Board (SWRCB) surface water permits and has a SWRCB surface water application in progress but currently does not divert or use surface water. This section presents the supply analysis and discussion. 6.1 Surface Water The District previously held a permit to divert surface water from Cold Creek (2015 District UWMP), but it discontinued this diversion in 1991 due to water quality constraints and has since cancelled that permit. The District also previously held six (6) permits for surface water diversion of the Upper Truckee River and tributaries for up to 4,424 AFY and limited to a maximum diversion of 2,760 by SWRCB Decision D 1152. The District has discontinued this diversion due to supply reliability concerns and has since cancelled these six (6) permits. 6.2 Groundwater The District draws its groundwater supply from the TSS underlying its service area. The California Department of Water Resources Groundwater Update 2003 Bulletin 118 defines the basin as the Tahoe Valley South Subbasin (Basin 6-5.01). 6.2.1 Basin Description As described in the District’s Alternate GSP and Bulletin 118, the groundwater basin is primarily unconsolidated sedimentary deposits within the TSS of the Tahoe Valley Groundwater Basin (Basin). Glacial deposits are predominant and include moraines and outwash that make up the predominant aquifers. The outwash deposits are generally sand, gravel, and cobble layers that are interbedded with silt and clay layers. Glacial melt waters and streams that drained moraines to the south produced outwash deposits. Later, glacial outwash deposits in some areas were eroded and replaced with stream channel deposits. Hardrock assemblages, including granitic, metamorphic, and volcanic rocks, are also common to the District and in the Basin. Granitic outcrops are common over a large area east, and within most of the District. In 1996, the fuel additive Methyl Tert-Butyl Ether (MTBE) was detected in one of the District’s wells. Gasoline/MTBE leaking from local gas station tanks travels easily through porous granitic soil into groundwater supplies. MTBE is a suspected carcinogen and even at low levels the chemical causes a foul taste and odor. The District has made significant efforts to combat this contaminant and, since 1996, MTBE has been one of the limiting factors to the District’s supply and operations. Since 1997, more than fifteen public water supply wells have been removed from service due to MTBE contamination. The District has been very proactive in addressing the challenges that MTBE contamination has caused. The District lobbied legislators and government officials to ban the use of MTBE as a fuel additive. The District was successful in enlisting the help of El Dorado County and the City of South Lake Tahoe to create an MTBE-free zone at South Lake Tahoe beginning in DRAFT 2025 Urban Water Management Plan, Page 6-2 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 uwmp_draft 04.29.2026.docx April 1999. In 2000, the District completed a comprehensive Master Plan Update, MTBE Water System Impacts and Mitigation Evaluation addressing the restoration of water production lost to MTBE contamination. Options studied included • constructing new wells, • securing surface water rights, • purchasing water, • rehabilitating its wells, • conserving water, and • installing treatment facilities to remove MTBE from wells. The District continues to implement and modify this plan as needed. In addition to wellhead treatment, the District has pursued a new drinking water well development program. The Bayview Well, put online in summer of 2007, produces 3,600 gallons per minute (gpm), and is the District’s highest producing well. South Upper Truckee Well No. 3, put online in 2008, adds another 1,200 gpm of supply. The District is currently planning the Tanglewood Well with a goal of achieving 2,000 gpm of supply. The District is also planning to redrill Sunset Well with a goal of achieving 2,000 gpm of supply. With these new wells and recent distribution system improvements, the District has completely returned to pre-MTBE production capability. Currently, there is a known tetrachloroethylene (PCE) plume within the west central portion of the TSS northeast of the Emerald Bay Road and South Lake Tahoe Boulevard Y area (also known as the South Y Area). Chlorinated hydrocarbons have been detected in the public water system (PWS), monitoring, and private wells north and south of the South Y Area since 1989, when these compounds were required to be first tested in regulated drinking water sources. Many of the PWS wells have since ceased operating due to PCE concentrations exceeding the drinking water standard of 5 micrograms per liter (µg/L). The majority of these South Y Area wells have been disconnected and many have been taken offline (i.e., ceased operation). PCE groundwater contamination has impacted the beneficial use of groundwater in the South Y Area. In order to address these impacts, Kennedy/Jenks Consultants, Inc. completed a Feasibility Study (South Y PCE Facilities Feasibility Study [Agreement D1712508], 2020) that evaluated the feasibility of cost-effective means of removing PCE from groundwater and manage existing groundwater sources to maintain adequate drinking water supply and quantity. The Feasibility Study evaluated remedial alternatives that will prevent further migration of contaminants and potential future impacts to downgradient water supply wells. Three different alternatives were considered in the Feasibility Study and it was determined that the preferred remedial alternative was targeted pumping with potable reuse, based on the evaluation and ranking of alternatives. Targeted pumping with potable reuse will best meet the Feasibility Study goals, control or remove PCE from groundwater and prevent further migration of contaminants and potential future impacts to downgradient water supply wells that serves or has served as a source of drinking water; and replace lost drinking water production caused by DRAFT 2025 Urban Water Management Plan, Page 6-3 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 uwmp_draft 04.29.2026.docx the impairment of groundwater sources in the South Y Area (Kennedy/Jenks Consultants, Inc., 2020a). During 2022, the District and the Lahontan Regional Water Quality Control Board (LRWQCB) continued a variety of plume characterization efforts including: October 2021 and April 2022 sampling of sentry wells installed upgradient of drinking water supply wells Non-municipal well sampling in July 2022 A soil gas investigation to evaluate the potential human health risks associated with potential soil vapor intrusion resulting from the South Y Plume in August 2022 Proposed Cleanup and Abatement Orders for three additional sites: Lake Tahoe Laundry Works, Big O Tires, and Former Norma’s Cleaners. The District’s water quality is reported in the Consumer Confidence Report (CCR), distributed to each customer annually. The latest CCR is included in Appendix C. 6.2.2 Groundwater Management The District first developed and adopted the GWMP in 2000, then updated it in 2005. This Plan was later updated again in December 2014 in accordance with the Groundwater Management Act (AB3030). The Sustainable Groundwater Management Act (SGMA) was adopted by the State in 2014. In 2015 the District was recognized by DWR as the Groundwater Sustainability Agency (GSA) for the portion of the TSS lying within its service area. In 2019, DWR approved the 2014 GWMP as an Alternate GSP for the TSS (DWR, 2019). The District and El Dorado Water Agency completed the first five-year update of the Alternate GSP which was accepted DWR by June 27, 2024. Groundwater management information is available at: https://www.stpud.us/groundwater-management. Within the 2005 GWMP, the District established a safe pumping yield of 9,528 AFY for its operation. Historical and current demand is below the safe yield and has been declining since 2007SGMA legislation and rules contain more detailed analysis requirements and criteria for managing groundwater. The 2016 Analysis of Basin Conditions report states that under the SGMA, the sustainable yield be at a minimum, less than or equal to the amount of groundwater recharge. The average recharge in the basin between 1983 and 2015 was 39,000 AFY. The available groundwater for extraction in the TSS is 32,050 AFY. The District operates well below this value and is expected to remain within the sustainable yield well into the future. In addition to developing the Alternate GSP and implementing SGMA, the District is also the reporting agency for the CASGEM program. Per the 2018 SGMA and CASGEM 2015 reporting, Basin 6-5.01 is a medium priority basin for the following reasons: 1) High reliance on Groundwater; 2) High Density of Public Supply Wells; 3) High Density of Production Wells; DRAFT 2025 Urban Water Management Plan, Page 6-4 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 uwmp_draft 04.29.2026.docx 4) Population Density; and 5) Documented Impacts/Impaired Water Quality (PCE and MTBE Contamination) As stated previously, the District has been, and continues to be, proactive in addressing groundwater contamination. 6.2.3 Overdraft Conditions The overall trend of the groundwater elevation data indicates that groundwater pumping is not causing any long-term declines in groundwater levels, or overdraft, in the Tahoe Valley South Basin. The water balance summary supports that the overall groundwater withdrawals are below the level that would result in an overdraft condition. As part of the groundwater annual report, review of water levels and groundwater modeling are conducted and would highlight any significant declines early so that management actions can be taken if needed. The most recent groundwater annual report for Water Year 2023 indicates that since WY2005, there is a cumulative change of groundwater in storage for the TSS of +15,357 AF indicating that overdraft is not a concern, Also, even with the high reliance on groundwater use within the TSS, the regulatory policies restricting growth throughout the Lake Tahoe Basin, will help to ensure that overdraft conditions do not develop in the future (TSS [6-5.01], Kennedy/Jenks Consultants, Inc., 2014). 6.2.4 Historical Pumping The District maintains 11 active supply production and two standby groundwater wells as of the end of 2025. Well production capacity ranges from 90 gpm up to 3,000 gpm. The District has reported as many as 34 wells from historic records. However, wells are abandoned over time due to age, failing production, and water quality issues such as the MTBE and PCE contamination issues. Past groundwater usage from 2021-2025 is presented in Table 6-1. Water quality and well age issues will continue to impact supply capacities. The District will continue to monitor water quality and well performance and implement treatment and/or new well programs to maintain supply reliability.

The system produces effluent at recycled water standards. However, the Porter-Cologne Water Quality Act prohibits the use of recycled water within the Lake Tahoe Basin. Therefore, all the wastewater treatment plant effluent is pumped to Alpine County and stored and used for agricultural purposes (i.e. beneficial reuse). This section presents the required information per the Guidelines. 6.3.1 Wastewater Collection, Treatment, and Disposal The District provides all wastewater treatment, collection, and disposal within its service area. The wastewater collection, treatment, and recycling disposal processes can treat 7.7 million gallon per day (MGD) and serves approximately 18,000 connections. The District’s award- winning collection system and wastewater treatment plant produces an average 4 MGD, 100 percent of which is recycled. However, the Basin Plan promulgated by the Lahontan Regional Water Quality Control Board prohibits reuse of treated wastewater within the Lake Tahoe Basin watershed, leaving no opportunities for re-use within the service area. The District’s treatment plant is currently permitted for “secondary 23” recycled water. This means the water has been oxidized and disinfected so that the median concentration of total coliform bacteria does not exceed a Most Probable Number (MPN) of 23 per 100 milliliters (ml) and the single day maximum does not exceed a MPN of 240 per 100 ml in any 30-day period. This quality of water is generally suitable for agricultural and some industrial uses. It is not suitable for unrestricted irrigation use. Since 1968, the District has delivered its treated effluent through a 26-mile export system, over Luther Pass (a vertical lift of 1,200 feet), to Alpine County. The recycled water is stored during the winter months in the 3,800-acre-foot Harvey Place Reservoir and distributed to six ranches and the District property in Alpine County for agricultural irrigation purposes in the dry summer months. Despite the prohibition on recycled water use within the District’s own service area, through a special legislative act in 2000, the District was able to install six fire hydrants along a short section of its recycled water export pipeline. These hydrants provide emergency fire suppression to a small residential community (that does not have municipal water service) and the District’s critical wastewater pumping station at the base of Luther Pass. The availability of recycled water in the event of a catastrophic fire in this heavily forested area provides a level of security to the residents, the District, and the Lake Valley Fire Department. Four additional hydrants were installed in Alpine County to provide similar fire protection as the export line makes its way to Harvey Place Reservoir. A 2015 project resulted in the use of recycled water for irrigation at the District’s Diamond Valley Ranch (DVR), located outside the Tahoe Basin. DVR has been used for producing alfalfa since 2017. In 2025, 147 AF of recycled wastewater was used in the irrigation of DVR between April 23rd and September 30th. Tables 6-2 and 6-3 present the required information regarding the wastewater collection, treatment, and discharge within the service area.

The District’s only option, at this time is to pump the treated wastewater to Alpine County for agricultural reuse. As reflected in Tables 6-4 and 6-5, the District plans to continue this practice for the foreseeable future.

The District does not transfer or exchange any of its groundwater to other water agencies on a long-term basis although they have supplied neighboring water companies through emergency interties on an as-needed basis. Should transfer opportunities arise in the future, the District will evaluate the opportunities at that time. 6.6 Emergency Interties The District maintains interconnections with the smaller private water companies within its service area. The interconnections are mostly intended to provide supply to the private companies during an emergency. The use of these connections during an emergency is not considered transfers or exchanges that provide additional supply on a regular basis. 6.7 Energy Intensity of the District Water System Water energy intensity is the amount of energy, calculated on a whole-system basis, required for use of water in a specific location, such as the District service area. DWR provides guidance for calculating the operational energy intensity of water, defined as the total amount of energy expended by the urban water supplier on a per AF basis to take water from the location where the urban water supplier acquires the water to its point of delivery. DWR requires that urban water suppliers only report the energy intensity associated with water management processes occurring within their operational control and not include energy embedded in water supplies purchased from a wholesale water agency. Table 6-7 below provides an estimate, using the total utility approach, of the water energy intensity of the District’s potable water system.

Climate change models have predicted that potential effects from climatic changes will result in increased temperature, early snow melt, and more intense storm events. The District prepared a Climate Action Plan for the Capital Improvement Program in December of 2019. This plan highlights the effects that climate change will have on the region and its impacts on water supply. The Climate Action Plan can be found here: https://www.stpud.us/documents#body_file-accordion_body_4_fa319ba3-51c3-4de4-b244- cec3d3661cea In the 2013 update of the DWR California Water Plan, the implications of future climate conditions are evaluated. These changing hydrological conditions could affect future planning efforts, which are typically based on historic conditions. DWR plans to update the California Water Plan in 2028; therefore, language from the 2013 update remains valid for this UWMP. The California Water Plan identifies the following probable impacts due to changes in temperature and precipitation: More winter runoff and less spring/summer runoff due to warmer temperatures. Greater extremes in flooding and droughts. Greater water demand for irrigation and landscape water due to increased temperatures and their impacts on plant water needs. In the 2019 Climate Action Plan for the Capital Improvement Program, the implications of future climate conditions are evaluated. These changing hydrological conditions could affect future planning efforts, which are typically based on historic conditions. The report identifies the following probable impacts due to changes in temperature, precipitation, runoff, erosion, and other variables: Longer Droughts Lower Groundwater Table Increase in Wildfire Potential Increase in Flooding Potential Increase in Landslides Wetter and Contracted Winter Season Increased seasonal visitation due to increased temperatures in the other parts of the state Even without population changes, water demand could increase. The District could face additional demands given the potential effects of climate change and will be monitoring water usage and groundwater conditions annually through the annual groundwater report preparation process. DRAFT 2025 Urban Water Management Plan, Page 7-1 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 uwmp_draft 04.29.2026.docx Section 7: Water Supply Reliability and Drought Risk Assessment This section summarizes the total water supplies for the District, describes the reliability of the supply, and presents the drought risk assessment. 7.1 Constraints on Water Sources The District’s supply is provided by local groundwater. The “safe yield” of this supply has been quantified in the District’s updated Alternate GSP as described in Section 6. The greatest risk for the water supply is groundwater contamination from PCE and MTBE, as well as naturally occurring arsenic and uranium. These issues have required the District to take wells out of service and carefully plan the location of new wells. As described in Section 6, the District is assessing the feasibility of PCE mitigation and has developed a plan for mitigating MTBE as well as other constituent impacts. These risks are not expected to impact District water sources over the period of this UWMP. The TSS historically has shown little response to hydrologic year types with groundwater levels within the TSS and the District’s water supply not being significantly impacted during the most recent statewide drought emergency declared in 2021 and largely rescinded in 2023. As part of the Alternate GSP annual water year reports, the District models the recent climatic conditions to assess the impacts to groundwater in storage and to evaluate whether, over multiple dry years, groundwater management actions including water conservation messaging, is necessary to maintain a sustainable groundwater condition. For the purposes of this UWMP, the District’s analysis indicates that the groundwater basin supply is highly reliable with no anticipated water supply shortage in the planning period of this Plan. The attached Water Shortage Contingency Plan, Appendix D, details actions the District can take to manage demand if supply constraints occur. 7.2 Reliability of Water Supplies The District relies solely on groundwater to meet its water demands. A summary of the potential factors limiting District supplies is presented in Table 7-1. Table 7-1: Factors Resulting in Inconsistency of Supply Water Supply Source Legal Environmental Water Quality Climatic Supplier produced groundwater None identified None identified Beneficial uses may be impacted by PCE or MTBE, Uranium, or Arsenic contamination. The TSS is largely dependent on precipitation for groundwater recharge. DRAFT 2025 Urban Water Management Plan, Page 7-2 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 uwmp_draft 04.29.2026.docx District groundwater supplies are not anticipated to be susceptible to inconsistencies resulting from legal or environmental impacts. The combination of groundwater recharge, basin storage volumes, pumping capacity, treatment capacity and actions to meet basin management objectives outlined in the Alternate GSP minimize possible water quality and climatic constraints and ensure consistency of District supplies. It should be noted, however, that groundwater contamination could cause inconsistency of supply if not addressed with proper mitigation. 7.3 Supply and Demand Comparisons The available supplies and water demands for the District’s service area were analyzed to assess the District’s ability to satisfy demands during three scenarios: a normal water year, single-dry year, and multiple-dry years. Table 7-2, Table 7-3, Table 7-4, and Table 7-5 in this section present the supplies and demands under the various water year scenarios for the 20- year planning period in 5-year increments. Because the TSS is not adjudicated, the District is not assigned an available supply. The District will pump sufficient supply to meet the demands during each of the single and multiple dry year scenarios, without requiring a reduction in demand or supplemental supplies. It is acknowledged that demand has been reduced during the recent drought period, but reductions have been regulatory-driven by the State Water Resources Control Board, and were not based on supply availability. Based on the available data, the District’s water supply appears to be slightly impacted by single or multiple dry water years. The District’s groundwater studies confirm that the wells that serve as the water supply are supported by local recharge and, in part, by Lake Tahoe. During the drought of 1985-1991, lake levels dropped 10 feet but the static water level decline observed in District wells was less than 4 feet and observed in only a few wells (2015 District UWMP). More recently, in the TSS Annual Report for Water Year 2023, groundwater elevations within the TSS declined from between the 2020 WY and 2021 WY since they were consecutive dry years about 75% of wells experienced declines of up to 5 feet from median water levels. Although WY 2022 was an average water year, recovery was marginal until the very wet WY 2023 returned groundwater elevations similar to WY 2019 levels. It is anticipated that the more extreme precipitation events in wet years that could occur as a result of climate change will result in sufficient groundwater recharge to replenish additional pumping that could occur as a result of hotter drier conditions. With this historical data in mind, it is anticipated that although climate change will result in more frequent and severe periods of drought, the District will continue to be able to meet demands. Additional discussion regarding climate change impacts is provided in Section 7.4.1.1. Table 7-2 presents supply volumes that are available during each of the dry year types. The District assumes the supply is 100 percent available during each year type.

Table 7-4 summarizes the District’s supplies available to meet demands during a single-dry year. It is assumed that the single-dry year supply and demand are equivalent to a normal year due to the basin’s robust supply even during the driest years. The District anticipates adequate supplies for 2030 to 2050 under single-dry water conditions.

This is to benefit and inform the demand DRAFT 2025 Urban Water Management Plan, Page 7-7 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 uwmp_draft 04.29.2026.docx management measures and water supply projects and programs to be included in the urban water management plan. 7.4.1 Data and Methodologies Used 7.4.1.1 Water Demands The water demands for this UWMP are based on 2025 actual demands derived from metered data and supply volumes. The volume of water supplied for 2025 was then escalated at the El Dorado County annual growth rate of 0.46 percent to project the water demand 25 years to 2050. For these projections, it was assumed that supply will be equal to demand and that the difference between the supply and water deliveries is the unaccounted-for water losses. The anticipated buildout water demand that was calculated in the Tahoe Demands report was not exceeded in this projection. In the Climate Action Plan for the Capital Improvement Program prepared in 2019 for the District, the US Environmental Protection Agency’s Climate Resilience Evaluation and Assessment Tool (CREAT) was applied to the District’s service area to understand the impacts of extreme weather. The CREAT results for an average annual temperature scenario show projected increases of 2.1°F to 2.5°F by 2035, and 4°F to 4.8°F by 2060 (CREAT 2019). Based on the CREAT analysis, the impact of climate change on the District’s water demands is not expected to be significant enough to include in the demand projections. Climate change impacts on the District’s water demands may need to be considered in the future. For example, analysis of a 10-year drought cycle scenario (referred to as the Q6 supply-deficit analysis) conducted for the Alternate GSP shows that after a drought of 6 consecutive years, the groundwater pumped in the TSS approaches the storage threshold which may cause undesirable effects on beneficial uses of groundwater. Spikes in demand may occur as a result of increased wildfire frequency as discussed in Section 4.3, however these spikes are usually of relatively short duration (e.g., days to weeks) and can likely be managed by local water conservation efforts. 7.4.1.2 Water Supplies This Drought Risk Assessment looks at the water supplies anticipated to be available 2026 through 2030 including any limitations due to infrastructure, regulations, and assuming drought conditions. Groundwater As described in Section 6, groundwater supplies are anticipated to be reliable sources of supply for the District. Table 7-6 reflects the anticipated supplies.

Within the District service area, there is sufficient groundwater supply for the projected water demands. In addition, there are very limited opportunities for additional supplies to be imported from other regions. The District will continue to monitor projected demands and supply reliability and assess needs to develop additional supplies as they arise.

The WSCP was adopted by the District Board on June 18, 2026. This section includes a brief description summary of the WSCP; the WSCP includes the drought risk assessment, described in Section 8 as required by the UWMP Guidelines. 8.1 Purpose of the WSCP The District has developed a WSCP to provide guidance if triggering events occur - whether from reduced supply, increased demand, or an emergency declaration - and to identify corresponding actions to be taken during the various stages of a water shortage. The plan includes voluntary and mandatory stages which are intended to be fair to all water customers and users while having the least impact on business, employment and quality of life for residents. 8.2 Annual Assessment Provisions in Water Code Section 10632.1 require that an urban water supplier such as the District, conduct an annual water supply and demand assessment (“Annual Assessment”), on or before July 1 of each year, to be submitted to DWR. As part of the WSCP, the District has identified the timeline, staff and outside agency coordination, and other actions necessary to conduct the Annual Assessment. 8.3 Shortage Stages The WSCP describes six water shortage stages corresponding to progressive ranges of up to 10, 20, 30, 40, and 50 percent shortages and greater than 50 percent shortage. For the District, water shortages are likely to be fire and/or infrastructure related and of short duration. The redundancy provide by multiple groundwater wells minimizes the shortages related to infrastructure. Water supply shortages because of drought are unlikely because of the robust aquifer supply. 8.4 Water Shortage Response Actions The WSCP identifies water shortage response actions, including: Consumption Reduction Method Public outreach Communication with Customers Operational changes Customer Compliance, Enforcement and Appeal and Exemption Procedures for Triggered Response Actions Supply augmentation Prohibitions on End Uses Penalties, Charges, Other Enforcement of Prohibitions DRAFT 2025 Urban Water Management Plan, Page 9-1 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 uwmp_draft 04.29.2026.docx Section 9: Conservation and Demand Management 9.1 Demand Management (2020 - 2025) The purpose of the Demand Management Measures (DMM) section of this UWMP is to (a) provide a description of the past water conservation programs that the District has implemented since 2007 to meet its urban water use reduction targets and (b) describe the activities and actions the District plans to use in the future to continue to maintain urban water use reduction. For the purposes of this UWMP the DMMs are categorized as “Foundational” and “Other”. Foundational DMMs, listed below, are those DMMs that the UWMP Act and Water Code specifically mention: a. Water waste prevention ordinances b. Metering c. Conservation pricing d. Public education and outreach e. Programs to assess and manage distribution system real loss f. Water conservation program coordination and staffing support Activities outside of the Foundational DMMs that encourage less water use in the District service area fall in the “Other DMM” category. 9.2 Foundational DMMs 9.2.1 Water Waste Prohibition The water waste prohibition is part of the District’s Administrative Code included in Appendix F, which includes designated irrigation days. The program is managed by the Water Conservation Specialist. With access to Automatic Metering Infrastructure (AMI) data, the District hires a seasonal Water Efficiency Technician and a seasonal Water Educator to lead the turf buyback program, offer Water Wise Landscape Consultations, coordinate individual conservation plans for high water use customers, process water conservation rebate applications, and enforce the water waste ordinance. The District can advertise the water waste ordinance in the local newspapers, social media, radio stations, and television station, as well as including reminders via bill inserts and emails through the Water Use portal and can increase outreach if needed. Exemptions and violations given are tracked in a Microsoft Excel™ spreadsheet and in the customer database. Enforcement is ongoing and is independent of water shortage stages. The District also has the Water Use portal where customers can view their water use, apply for conservation rebates and services, and receive automated leak alerts. The Water Conservation Specialist manages the Water Use program and actively contacts and follows-up with customers to locate leaks. Once a leak has been fixed, the customer can submit a copy of their invoices to be reimbursed through the leak repair rebate and can apply for a leak adjustment on their bill.

As of 2025, the District is estimated to be 99.9% metered. Once a meter is installed, the customer is switched to volumetric billing per the current rate structure. The District does not evaluate metering for water savings as it provides an indirect benefit to the other quantifiable programs. The District utilizes meters and tiered pricing to develop a value of water for its customers who then can utilize the quantifiable programs to reduce their water use. The installation of meters and AMI is also a direct positive use of grant funding. As noted in Section 4.1, installation of metering and implementation of the District’s comprehensive conservation program has contributed to +over 43% reduction in water use per account. 9.2.3 Conservation Pricing As required by AB 2572, the District is converting existing residential connections to meters. Within 12 months of converting, these accounts are billed on volumetric rates. The current water rate structure includes a two-tier volumetric charge for all residential customers. The current rate structure is available on the District’s website at: https://www.stpud.us/rate-changes As of July 1, 2025, the residential consumption rates are divided into two tiers, with a higher rate for usage exceeding 15 hundred cubic feet (CCF) per month. The District will continue to update its rate structure as necessary and when all customers become metered. The District does not evaluate conservation pricing for water savings as it provides an indirect benefit to the District’s other quantifiable programs. The District utilizes meters and tiered pricing to develop a value of water for its customers who then can utilize the other programs to reduce their water use. Conservation is also achieved through the automatic water leak system and metering within the District. 9.2.4 Public Education and Outreach The District provides information on its water conservation program and on water conservation to the public through speakers for community groups, events, and schools. In addition, customers receive information through paid and public service advertising. The District coordinates with other governmental agencies, industry groups, public interest groups, and the media to continue offering information to customers. The District also uses social media and digital ads to provide information to customers. Additionally, the District also maintains a school education program as part of its outreach efforts. The District is a member of the South Tahoe Environmental Education Coalition and educates students through the Coalition’s programs. Programs include annual tours of the wastewater treatment plant for 5th graders and DRAFT 2025 Urban Water Management Plan, Page 9-3 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 uwmp_draft 04.29.2026.docx select 9 – 12th graders, Wonders of Water curriculum for K – 6th graders, Woods, Water and Wildlife programs for K – 2nd graders, Children’s Forest programs for 3rd – 4th graders, and the Environmental Education Days for 9th – 12th grades. The District continues to evaluate its public outreach program and will modify it as necessary. There is no current method in the industry to evaluate this program. The outreach efforts support the District’s other customer-specific programs that can be evaluated for water savings. Anecdotally, during the 2014-2017 drought, the broad statewide message regarding reduction of water use, when combined with local messages achieved the target 25% reduction in water use. 9.2.5 Programs to Assess and Manage Distribution System Real Loss The District maintains a surface leak repair program. The program includes District staff identifying and repairing leaks in the distribution system each year. For example, 249 leaks were identified in the distribution system in 2025. The District has budgeted to continue these services annually. The efforts result in an average of 6-10 main, service, and fire hydrant leaks detected during each inspection period. Pre-screening system audits are completed each year to prioritize areas for inspection. The District also maintains 13 District Metered Areas to assist in determining which areas of the water system are the primary sources of water loss. The District maintains a leak data spreadsheet to track location and type of leak and other information such as pipe material. The District completes the American Water Works Association water loss audit annually. In 2024, the audit procedure identified approximately 11.4 percent unaccounted for system losses. The District will continue to conduct the AWWA water loss audit and identify and repair leaks as needed. In addition to the leak data spreadsheet, the District tracks the number of miles of pipeline surveyed and repaired, along with annual dollar expenditures. The water savings from this measure are difficult to track at this time as the system is not fully metered. However, efforts will be made to try to determine water savings based on approximate leak rate and approximate flow volume of repairs made. As the system becomes fully metered, the estimates and calculations for the entire system will become more definitive. 9.2.6 Water Conservation Program Coordination and Staffing Support The District’s conservation program is managed by the Water Conservation Specialist who manages the District's water conservation program, including water-saving incentives, community education, outreach, and enforcement; analyzes program goals, Water Use Portal, performance measures, and sources of funding; and oversees field audits and consultations. In addition, the Customer Account Specialist is a full-time position managing the meter program, including AMI data.

Water Wise house calls are done by the District and is offered during May – October. 9.3 Other DMMs In addition to the conservation programs required by the UWMP Guidelines, the District also maintains additional programs specific to their unique customer demographics and water use. The additional programs are listed below, with additional information included on the District’s website. 9.3.1 Residential Programs Water Wise House Call Water Wise Landscape Consultation Turf Buy-Back Program Irrigation efficiency evaluations Leak detection assistance Direct Distribution Program Discounts through Cal WEP 9.3.2 Commercial Programs Commercial water use review Turf Buy Back Program Water Wise Landscape Consultation Irrigation efficiency evaluations Leak detection assistance Direct Distribution Program Discounts through Cal WEP 9.4 Planned DMMs to Meet Water Use Targets District customers have already achieved demand reductions sufficient to meet SBX7-7 water use targets. The District will continue to perform Foundational DMMs. These DMMs, as well as residential and commercial programs and meeting, will help the District keep its GPCD within or lower than the SBX7-7 water use targets.

A copy of the UWMP is available for public viewing at the District Office during normal business hours located at 1275 Meadow Crest Drive, South Lake Tahoe, CA 96150. 10.4 Implementation The 2025 UWMP presents a description of: the water service area, the existing and planned supply sources, water use, continued SBx7-7 (20x2020) gpcd compliance, water supply reliability, water conservation and demand management measures, as well as plan adoption, submittal, implementation, and economic impact. The District has continued to maintain and improve its groundwater supply infrastructure by developing new wells and conducting maintenance and improvements on existing wells. The District has maintained its efforts for the conservation program with positive results evidenced by decreased water demands. All foundational conservation best management practices are implemented. The District will continue to monitor its gpcd water usage and investigate alternative programs based on need. The District has been a signatory of the California Urban Water Conservation Council (now California Water Efficiency Partnership) and utilizes partnership programs as necessary. Implementation of the 2025 UWMP will be tracked through a variety of methods. Supply reliability issues will mostly be tracked through the District’s water quality monitoring program, well infrastructure program, and production values. Progress and results of the conservation program will continue to be tracked and submitted to the State as required to for UWMP updates and AB 1420 compliance requirements.

Tradúzcalo o hable con alguien que lo entienda bien.PWS ID#: CA0910002 Our Commitment The South Tahoe Public Utility District (District) is pleased to present to you this year’s annual water quality report. This report is a snapshot of last year’s water quality covering all testing performed between January 1 and December 31, 2024. Included are details about your sources of water, what it contains, and how it compares to standards set by regulatory agencies. Our constant goal is to provide you with a safe and dependable supply of drink- ing water. We want you to understand the efforts we make to continually improve and protect our water resources. Where Does My Water Come From? The District’s network of 11 active wells supplies water to over 14,000 homes and businesses. All your drink- ing water is pumped from the aquifer beneath our feet – the Tahoe Valley South Subbasin. More information about our aquifer and groundwater management can be found at stpud. us/drinking-water. Important Health Information Some people may be more vulnerable to contami- nants in drinking water than the general population. Immunocompromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants, can be particularly at risk from infections. These people should seek advice about drink- ing water from their health-care providers. U.S. Environmental Protection Agency (U.S. EPA)/Centers for Disease Control and Prevention (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline at (800) 426-4791 or epa.gov/safewater. Substances That Could Be in Water The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water include: Microbial Contaminants, such as viruses and bacteria, that may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife. Inorganic Contaminants, such as salts and metals, that can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming. Pesticides and Herbicides that may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses. Organic Chemical Contaminants, including synthetic and volatile organic chemicals, that are by-products of industrial processes and petroleum production and can also come from gas stations, urban stormwater runoff, agricultural application, and septic systems. Radioactive Contaminants that can be naturally occurring or the result of oil and gas production and mining activities. To ensure that tap water is safe to drink, the U.S. EPA and the State Water Resources Control Board (SWRCB) prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. U.S. Food and Drug Administration regulations and California law also establish limits for contaminants in bottled water that provide the same protection for public health. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the U.S. EPA’s Safe Drinking Water Hotline at (800) 426-4791. QUESTIONS? For more information about this report, or for any questions relating to your drinking water, please call Dan Arce, Laboratory Director, at (530) 544-6474, ext. 6231. Testing for Radon Our wells were last monitored for radon in 2023 and the results of that testing are provided later in this report. Radon is a naturally occurring radioactive gas that you cannot see, taste, or smell. It is found throughout the U.S. Radon can move up through the ground and into a home through cracks and holes in the foundation. Radon can build up to high levels in all types of homes. Radon can also get into indoor air when released from tap water from showering, washing dishes, and other household activi- ties. Compared to radon entering the home through soil, radon entering the home through tap water will, in most cases, be a small source in indoor air. Radon is a known human carcinogen. Breathing air containing radon can lead to lung cancer. Drinking water containing radon may also cause increased risk of stomach cancer. If you are concerned about radon, test the air in your home. Testing is inexpensive and easy. You should pursue radon removal if the level of radon in your air is 4 picocuries per liter (pCi/L) of air or higher. There are simple ways to fix a radon problem. For additional information, call California’s Radon Program at (800) 745-7236, the U.S. EPA’s Safe Drinking Water Hotline at (800) 426-4791, or the National Safety Council Radon Hotline at (800) 767-7236. Source Water Assessment and Protection The District continues to work diligently to protect and maintain our groundwater quality and an adequate water sup- ply. The District’s Groundwater Management Plan (California Water Code, section 10750) is on file with the California Department of Public Health (CDPH). You may view the document by visiting the District’s website at stpud.us or request a copy by calling customer service at (530) 544-6474. The District has an ongoing drinking water source development program that seeks potential drinking water well locations. Due to the volume of the average annual Sierra snowpack and Lake Tahoe itself, our aquifer has a significant recharge capability. Groundwater in South Lake Tahoe is generally of excellent quality, though it has faced threats from both natural and human- made contaminants. Methyl tert butyl ether (MTBE) and tetrachloroethylene (PCE) plumes in the South Y area led the District to remove affected wells from service and develop new, uncontaminated sources. Naturally occurring arsenic, uranium, and gross alpha particle activity have been found in parts of the aquifer, with one District well requiring arsenic treatment to meet water quality standards. Infiltration basins used for stormwater recharge also pose potential risks, but these are effectively managed through careful well siting, design, and wellhead treatment. Community Participation The District is governed by an elected five-member board of directors. Board meetings are held on the first and third Thursday of each month at 2:00 p.m. in the District boardroom at 1275 Meadow Crest Drive. All meetings are open to the public, and the District encourages our customers to attend, ask questions, and provide feedback. What Are PFAS? Per- and polyfluoroalkyl substances (PFAS) are a group of manufactured chemicals used worldwide since the 1950s to make fluoropolymer coatings and products that resist heat, oil, stains, grease, and water. During production and use, PFAS can migrate into the soil, water, and air. Most PFAS do not break down; they remain in the environment, ultimately finding their way into drinking water. Because of their wide- spread use and their persistence in the environment, PFAS are found all over the world at low levels. Some PFAS can build up in people and animals with repeated exposure over time. The most commonly studied PFAS are perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS). PFOA and PFOS have been phased out of production and use in the United States, but other countries may still manufacture and use them. Some products that may contain PFAS include: •Some grease-resistant paper, fast food containers/wrappers, microwave popcorn bags, pizza boxes •Nonstick cookware •Stain-resistant coatings used on carpets, upholstery, and other fabrics •Water-resistant clothing •Personal care products (shampoo, dental floss) and cosmetics (nail polish, eye makeup) •Cleaning products •Paints, varnishes, and sealants Even though recent efforts to remove PFAS have reduced the likelihood of exposure, some products may still contain them. If you have questions or concerns about products you use in your home, contact the Consumer Product Safety Commission at (800) 638-2772. For a more detailed discussion on PFAS, please visit atsdr.cdc.gov/pfas/index.html. Arsenic Regulation Arsenic contamination of drinking water sources may result from either natural or human activities. Volcanic activity, erosion of rocks and minerals, and forest fires are natural sources that can release arsenic into the environment. Although about 90 percent of the arsenic used by industry is for wood preservative purposes, it is also used in paints, drugs, dyes, soaps, metals, and semiconductors. Agricultural applica- tions, mining, and smelting also contribute to arsenic releases. Arsenic is usually found in the environment combined with other elements such as oxygen, chlorine, and sulfur (inorganic arsenic) or carbon and hydrogen (organic arsenic). Organic forms are usually less harmful than inorganic forms. Low levels of arsenic are naturally present in water--about 2 parts arsenic per billion parts water (ppb), so you normally take in small amounts of arsenic in the water you drink. Some areas of the country have unusually high natural levels of arsenic in rock, which can lead to unusually high levels of arsenic in water. In January 2001, the U.S. EPA lowered the arsenic MCL from 50 to 10 ppb in response to new and compelling research linking high arsenic levels in drinking water with certain forms of cancer. All water utilities were required to implement this new MCL in January 2006. Removing arsenic from drinking water is a costly procedure but well worth the expenditure considering the health benefits. For a more complete discussion, visit the U.S. EPA’s arsenic web page, epa.gov/dwreginfo/drinking-water-arsenic-rule-history. Test Results The following tables list the drinking water contaminants monitored for the calendar year of this report, unless otherwise noted. The presence of contaminants in the water does not necessarily indicate that the water poses a health risk. The U.S. EPA and SWRCB require us to monitor for certain contaminants less often than once per year based on results of previous testing. The District monitors for more contaminants than are listed in these tables. Contaminants not detected during testing are not shown in the tables. The state recommends monitoring for certain substances less than once per year because the concentrations of these substances do not change frequently. In these cases, the most recent sample data is included, along with the year in which the sample was taken. The District participated in the fifth stage of the U.S. EPA’s Unregulated Contaminant Monitoring Rule (UCMR5) program by performing additional tests on our drinking water. UCMR5 sampling benefits the environment and public health by providing the U.S. EPA with data on the occurrence of contaminants suspected to be in drinking water to determine if it needs to introduce new regulatory standards to improve drinking water quality. Unregulated contaminant monitoring data is available to the public, so please feel free to contact us if you are interested in obtaining that information. If you would like more information on the U.S. EPA’s Unregulated Contaminant Monitoring Rule, please call the Safe Drinking Water Hotline at (800) 426-4791 or visit https://www.epa.gov/dwucmr/learn-about-unregulated-contaminant-monitoring-rule.

Lead in Home Plumbing Lead can cause serious health effects in people of all ages, especially pregnant people, infants (both formula-fed and breastfed), and young children. Lead in drinking water is primarily from materials and parts used in service lines and in home plumbing. The District is responsible for providing high-quality drinking water and remov- ing lead pipes but cannot control the variety of materials used in the plumbing in your home. Because lead levels may vary over time, lead exposure is possible even when your tap sampling results do not detect lead at one point in time. You can help protect yourself and your family by identifying and removing lead materials within your home plumbing and taking steps to reduce your family’s risk. Using a filter certified by an American National Standards Institute-accredited certifier to reduce lead is effective in reducing lead exposures. Follow the instructions provided with the filter to ensure it is used properly. Use only cold water for drinking, cooking, and making baby formula. Boiling does not remove lead from water. Before using tap water for drinking, cooking, or making baby formula, flush your pipes for several minutes. You can do this by running your tap, taking a shower, or doing laundry or a load of dishes. If you have a lead or galvanized service line requiring replacement, you may need to flush your pipes for a longer period. If you are concerned about lead and wish to have your water tested, contact the District’s laboratory at (530) 544-6474, ext. 6231. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at epa.gov/safewater/lead. To address lead in drinking water, public water systems were required to develop and maintain an inventory of service line materials by October 16, 2024. Developing an inventory and identifying the location of lead service lines is the first step for beginning to replace lead service lines and protecting public health. While no lead water service lines have been identified in the District’s system to date, service lines with unknown materials are still being assessed. More information about the District’s lead service inventory may be found at stpud.us/water-service-line-inventory. Please contact us at (530) 544- 6474 if you would like more information about the inventory or lead sampling that has been done.

Reliability Analysis From DWR Guidebook p. 198 Water Code Section 10632(a)(1) The analysis of water supply reliability conducted pursuant to Section 10635. From Guidebook: Water Code Section 10632(a)(1) The analysis of water supply reliability conducted pursuant to Section 10635. The narrative in this section examines (a) the findings related to water system reliability conducted pursuant to Water Code Section 10635, and (b) the key issues that may create a shortage condition when looking at the Supplier’s water asset portfolio. More specifically, this section provides a concise narrative, summarizing the Supplier’s water supply analysis in Chapter 6 and its water reliability findings in Chapter 7, recognizing that the WSCP can be a stand-alone document that will be submitted with the 2025 UWMP. The Supplier is encouraged to consider all issues—foreseeable or unforeseeable—that could lead to water supply shortages. For example, a Supplier that relies exclusively on groundwater may show that its water supplies are reliable under all statutorily required conditions, but that a low probability, high impact issue—like the sudden presence of an unforeseen toxin—may require shuttering the main groundwater pumping system and activating the WSCP. This section would provide the context for evaluation of threats to water supply reliability that are identified in the WSCP. The South Tahoe Public Utility District (District) provides water service throughout the South Lake Tahoe area (Figure 1-1) Water supply is provided by eleven (11) active drinking water wells and two (2) standby wells which supply more than 14,000 homes and businesses. All the District’s drinking water is pumped from the Tahoe South Subbasin (designated by the California Department of Water Resources (DWR) as Groundwater Subbasin 6-005.01) of the Tahoe Valley Groundwater Basin (6-005)). The District is the largest water purveyor in the Tahoe South Subbasin (TSS). The District does not currently serve water from Lake Tahoe or any other surface water source for potable use. The TSS historically has shown little to no response to hydrologic year types, and the District’s water supply was not severely impacted during the recent statewide drought emergency declared in 2021 under the California Emergency Services Act (2020-2023 Event). Figure 1-2 presents groundwater elevations from the 2004 Water Year (WY) through 2023 WY. The District assumes the TSS supply is highly reliable. Based on the five-year drought risk assessment, water supply shortages are anticipated during the first four years of a five-year drought. The District’s future supply projects are expected to sufficiently increase supply to mitigate the projected supply shortages. Therefore, this Water Shortage Contingency Plan (WSCP) is most likely triggered due to the restraints of groundwater conveyance and focuses on relatively short and extreme events such as wildfire, power outage, loss of critical infrastructure, providing emergency supply to neighboring agencies per Mutual Aid Agreement occurring during Dry Years, which has the same content as UWMP Table 7-7 – Drought Risk Assessment, shows the District’s near-term water supply reliability assuming 5-year drought.

(B) The key data inputs and assessment methodology used to evaluate the urban water supplier’s water supply reliability for the current year and one dry year, including all of the following: (i) Current year unconstrained demand, considering weather, growth, and other influencing factors, such as policies to manage current supplies to meet demand objectives in future years, as applicable. (ii) Current year available supply, considering hydrological and regulatory conditions in the current year and one dry year. The annual supply and demand assessment may consider more than one dry year solely at the discretion of the urban water supplier. (iii) Existing infrastructure capabilities and plausible constraints. (iv) A defined set of locally applicable evaluation criteria that are consistently relied upon for each annual water supply and demand assessment. (v) A description and quantification of each source of water supply. Water Code Section 10632.1. An urban water supplier shall conduct an annual water supply and demand assessment pursuant to subdivision (a) of Section 10632 and, on or before July 1 of each year, submit an annual water shortage assessment report to the department with information for anticipated shortage, triggered shortage response actions, compliance and enforcement actions, and communication actions consistent with the supplier’s water shortage contingency plan. An urban water supplier that relies on imported water from the State Water Project or the Bureau of Reclamation shall submit its annual water supply and demand assessment within 14 days of receiving its final allocations, or by July 1 of each year, whichever is later. These Annual Assessment procedures described herein are one tool to be used to determine if a water shortage is to be declared. New provisions in Water Code Section 10632.1. requires that an urban water supplier, such as the District, conduct an annual water supply and demand assessment (“Annual Assessment”), on or before July 1 of each year, to be submitted to DWR. The requirement to perform the DRAFT 2025 Water Shortage Contingency Plan, Page 2-2 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 wscp_draft 04.30.2026.docx Annual Assessment begins in July 2022. The procedures for performing the Annual Assessment are to be detailed in an urban suppliers’ WSCP. Water shortages occur with unpredictable frequency, intensity, and duration. Developing and maintaining a healthy water supply to serve its customers has always been an ongoing District priority, and the District wants to be prepared for water shortages. The District is 100% reliant on groundwater for water supply. El Dorado Water Agency is the Groundwater Sustainability Agency (GSA) for the portion of the TSS within the District’s service area. As the GSA, El Dorado Water Agency is required to submit an Annual Report to DWR to report the current condition of the groundwater basin per CWC and Groundwater Sustainability (GSP) Regulations. The main reporting aspects within the TSS annual report include descriptions of groundwater conditions over the preceding WY but are not limited to: Climate in terms of total precipitation and water year type; Groundwater conditions in terms of groundwater levels and groundwater recharge (as calculated using the South Tahoe Groundwater Model); Groundwater extractions in terms of groundwater pumpage and water use; and Annual and cumulative changes in groundwater storage (as derived from the flow budget calculated using the South Tahoe Groundwater Model). In July 2019, DWR approved the District’s 2014 Groundwater Management Plan (2014 GMP) and additional plans, reports and other documents related to the 2014 GMP as an approved Alternative to a GSP. As part of DWR’s assessment, eight (8) recommended actions (RAs) were presented describing information to be included in the first 5-year update of the approved Alternative GSP. The update to the Alternative GSP was approved by DWR in April 2022. Water supply projections and hydrologic conditions are significant components in deciding when a water shortage response is needed. The amount of the water supply shortage contributes to the severity of shortage declared and the necessary level of response from the District and customers. The procedure described in this Chapter was developed to help satisfy the water demand requirements for the approved Alternative GSP and the water supply and demand assessment requirements for the WSCP. 2.1 Timeline for Conducting the Annual Assessment Figure 2-1 provides procedures for performing the Annual Assessment. The figure outlines actions for a normal year and one year of drought. By gathering information on groundwater conditions over the preceding WY in December, the District will get a snapshot of the available water supply conditions for the Annual Assessment, in terms of change in groundwater storage within the TSS. The annual change in groundwater storage is the difference between groundwater recharge and discharge. Tracking this annual difference allows the District to monitor the amount of groundwater stored in the TSS. The District can then allocate resources to mitigate supply deficiencies, if any, and start outreach to customers to manage demand. Major actions are proposed in January to March, when an initial estimate of supply is made and compared to demand. A final annual assessment is proposed in May.

For many of the supplies, the effects of weather are seen over the short-term and are reflected in seasonal changes in groundwater elevations. Water Year Classification. The District monitors total precipitation measured at the National Resources Conservation Service SNOTEL station 508: Hagan’s Meadow, CA. Based on water years 1985 through 2019, total accumulated precipitation measures at SNOTEL 508: Hagan’s Meadow, CA is classified as “Very Wet”, “Wet”, “Above Normal”, “Normal”, “Below Normal”, “Dry”, and “Critical”. The total precipitation is an input used to calculate groundwater recharge in the groundwater model. By this manner the District directly considers the impacts of climate in terms of total precipitation and groundwater recharge on available water supply and will affect how the District considers demand in the current year and the next year as a drought year. 2.3 Water Supply Assessment The District will update the groundwater model on an annual basis to calculate the changes in groundwater storage presented in the TSS Annual Report. Tracking the annual changes in groundwater storage will allow the District to quantify the available water supply in terms of cumulative change in groundwater storage (in AF) within the TSS and District’s service area (see Figure 1-1). 2.4 Water Demand Assessment DWR guidance for the Annual Assessment is to consider the expected water use in the upcoming year, based on recent water use, and before any projected response actions a Supplier may trigger under its WSCP. The District will follow the guidance in the Annual Assessment template to report the unconstrained current demand and projected demand for the subsequent year, in terms of total monthly and annual groundwater pumpages for District Wells.

As required by Water Code Section 10632(a), the Supplier’s WSCP shall include its specific procedures—akin to an instruction manual—that describe annual steps and timing to complete the Annual Assessment, such that it can be consistently followed year-after-year, regardless of changing Supplier staff undertaking the steps. Water Code requires that the following shall be described by the Supplier in its WSCP for this element. The District staff will compare the water budget based on groundwater model output and the anticipated demand based on groundwater pumpages and determine if a supply shortage is anticipated, the level of shortage, and determine whether the shortage condition requires implementation of its WSCP. 2.6 Coordination with Cities and Counties Should a water shortage be declared, the District will coordinate with any City or County within which it provides water supply services for the possible proclamation of a local emergency, as defined in Section 8558 of the Government Code. DRAFT 2025 Water Shortage Contingency Plan, Page 3-1 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 wscp_draft 04.30.2026.docx Chapter 3: Six Standard Water Shortage Stages From DWR Guidebook Water Code Section 10632(a)(3) (A) Six standard water shortage levels corresponding to progressive ranges of up to 10, 20, 30, 40, and 50 percent shortages and greater than 50 percent shortage. Urban water suppliers shall define these shortage levels based on the suppliers’ water supply conditions, including percentage reductions in water supply, changes in groundwater levels, changes in surface elevation or level of subsidence, or other changes in hydrological or other local conditions indicative of the water supply available for use. Shortage levels shall also apply to catastrophic interruption of water supplies, including, but not limited to, a regional power outage, an earthquake, and other potential emergency events. (B) An urban water supplier with an existing water shortage contingency plan that uses different water shortage levels may comply with the requirement in subparagraph (A) by developing and including a cross- reference relating its existing categories to the six standard water shortage levels. 3.1 Definitions/Criteria Establishing Shortage The District currently applies a three-stage plan during declared water shortages in accordance with its Administrative Code updated on April 2, 2026. The updated Administrative Code will go into effect May 2, 2026. The District has a reliable groundwater resource as described in the Water Supply Reliability Analysis. Applying WSCP percent shortages up to 50% of the total source capacity for the water system was calculated and compared to the District’s monthly water production over the past 30 years. Comparison of these values indicates that the District would likely experience water shortage conditions under the following scenarios: A water shortage in a neighboring water system(s) could result in an emergency condition requiring the District to provide emergency water through inter-tie(s) under a mutual aid agreement. Under below normal water year or dry water years, unexpected delivery of emergency water could possibly trigger 10%-20% water shortage for the District’s system. An extended regional power outage (RPO) during a maximum demand in summertime would result in 40%-50% water shortage. A wildfire with extended RPO during a maximum demand in summertime would result in >50% water shortage. The District decided to crosswalk the current water shortage levels in the Administrative Code to those mandated by the State. Table 3-1 summarizes the water shortage plan and stages of action. DRAFT 2025 Water Shortage Contingency Plan, Page 3-2 South Tahoe Public Utility District https://kjcnet.sharepoint.com/sites/southtahoepublicutilitydistrict-2025uwmpupdate/shared documents/general/public review draft/for wp/stpud 2025 wscp_draft 04.30.2026.docx Table 3-1: Cross-reference for Standard vs Supplier Shortage Levels (DWR Table 8-1) Water Code Section 10632(a)(3)(B) Supplier uses the Standard six levels of water shortage. Supplier will not complete table. Standard Shortage Levels Percent Shortage Range Suppliers Shortage Levels Percent Shortage Range 1 Up to 10% Minor Supply Reduction (a) 0%-10% 2 Up to 20% 10%-20% 3 Up to 30% Significant Water Shortage Requiring Significant Supply Reduction (e.g., RPO) 20%-30% 4 Up to 40% 30%-40% 5 Up to 50% Water Emergency Requiring Severe Reductions 40%-50% 6 >50% Catastrophic Water Shortage Requiring Critical Reductions >50% NOTES: (a) This water shortage condition could be triggered if the District provides emergency supply to neighboring water systems under below normal or dry water years. 3.2 Determining Water Shortage Reductions The District assigns requirements and actions to apply in each stage designed to achieve the necessary demand reduction. These are described further in Section 4.2 The District will monitor monthly or weekly production values for each of its wells, depending on shortage conditions. The District will also compare production to actual customer usage to determine demand reduction results and identify customers that may require assistance to achieve demand reductions. Based on production and demand trends, the District will act to adjust the water shortage stage declaration, as necessary. 3.3 Actions to Prepare for Catastrophic Interruption The District has developed an Emergency Operations Plan (EOP). This EOP guides response to unpredicted catastrophic events that might impact water delivery including regional power outages, earthquakes or other disasters and outlines standard operating procedures for all levels of emergency, from minor accidents to major disaster. In addition, the District has prepared a Local Hazard Mitigation Plan (LHMP). These plans have been coordinated with neighboring agencies.

The LHMP is currently being updated by STPUD. In the updated LHMP, the District will consider seismic risk to water facilities and identify mitigation measures to lessen the risk, if needed. The previous plan is available athttps://www.stpud.us/plan-documents, and meets the requirements of the federal Disaster Mitigation Act of 2020 (Public Law 106-390) as well as the requirements of Water Code Section 10644. A copy of the 2019 LHMP will be submitted to DWR with the adopted WSCP. The District recently completed a review of their risk and reliability analysis for their water system.

(B) Locally appropriate demand reduction actions to adequately respond to shortages. (C) Locally appropriate operational changes. (D) Additional, mandatory prohibitions against specific water use practices that are in addition to state- mandated prohibitions and appropriate to the local conditions. (E) For each action, an estimate of the extent to which the gap between supplies and demand will be reduced by implementation of the action. Stages of Action to Respond to Water Shortages 4.1 Supply Augmentation Actions Any water shortage event should trigger a review of potential sources for supplemental water supply. Since the groundwater basin is highly reliable based on the historical record, potential actions for supplemental water could be alleviated by turning on District standby wells, rehabilitate existing wells to meet target flow rates, and construct new wells if needed. The District may also adjust the delivery of emergency water to neighboring water purveyors during water shortage event if needed. Additional supply sources for consideration by the District include developing surface water from Lake Tahoe with the water right, and other alternatives based on the actual circumstances at that time. Table 4-1 summarizes the supply augmentation actions that the District could take under water shortage conditions.

[see below] (C) A statement that an urban water supplier shall coordinate with any city or county within which it provides water supply services for the possible proclamation of a local emergency, as defined in Section 8558 of the Government Code. Water Code Section Division 1, Section 350 Declaration of water shortage emergency condition. The governing body of a distributor of a public water supply, whether publicly or privately owned and including a mutual water company, shall declare a water shortage emergency condition to prevail within the area served by such distributor whenever it finds and determines that the ordinary demands and requirements of water consumers cannot be satisfied without depleting the water supply of the distributor to the extent that there would be insufficient water for human consumption, sanitation, and fire protection. Description of legal authorities to Implement and Enforce Shortage Response Actions The General Manager, and other District authorized representatives have the duty and are authorized to enforce all provisions stated in Section 3.4 of the District’s Administrative Code under determined shortage conditions. Based on the outcome of the Annual Water Supply and Demand Assessment, the General Manager will work with the Board to implement the WSCP.

(B) A description of mitigation actions needed to address revenue reductions and expense increases associated with activated shortage response actions described in paragraph (4). (C) A description of the cost of compliance with Chapter 3.3 (commencing with Section 365) of Division 1 [retail urban suppliers only]. The District water rate structure includes rates for metered and unmetered customers. The metered rates for single family connections include two tiers, and all rates include a base fixed charge. The base fixed charge will not be affected by a water shortage. There will be an expected decrease in volumetric revenue if demands are reduced. District energy expenses are expected to decrease slightly with reduced water demands, as less water will be pumped, reducing electrical costs. The District will follow the Administrative Code to issue fines to a water user’s bill in case of violation and shall be reimbursed for its costs and expenses in enforcing the provisions under conservation. Other District operating costs are not expected to change significantly during water shortage conditions. Though there may be reduced volumetric revenue, it is not expected to impact District finances significantly. The District maintains a reserve fund to address financial and supply needs should revenues decrease significantly and/or any of the wells be taken offline. In addition, if the supply shortage is projected to last longer, the District will investigate and implement as necessary water crisis/emergency pricing to offset potential long-term revenue reductions.

Certain aspects of water conservation can be readily monitored and evaluated, such as metered water use and production quantities. Other aspects such as public education are more difficult to monitor in terms of effectiveness. When severe shortage occurs and some degree of mandatory reduction is required, a program’s effectiveness can be judged directly by water billings. In these cases, targeted results must be met and even reluctant customers will, on the whole, meet the goals. Specific methods to evaluate effectiveness of water conservation programs to be employed by the District are: 1. Monitoring of Metered Water Usage – This will determine how much has been used. Compiling statistics to track usage of customer groups to determine trends is currently being done through the water billing computer system. Meter readings/billings can be compared and analyzed to determine the effectiveness of conservation for all customer classes. 2. Monitoring Production Quantities – The Field Operations Manager and Water and Sewer Operations (FOMT) Supervisor monitor the accuracy of the monthly production totals. The totals are reviewed by the Water Resources Manager and incorporated into the monthly water supply report to the State Water Resources Control Board by the Water Conservation Specialist. To verify that conservation reduction goals are being met, production and metered usage reports will be provided to the General Manager when a shortage stage is in effect. Water production figures will be compared to previous year production figures for the same time period to ascertain if conservation goals are being reached. Additional actions available to the District include: 1. Complete the process of customer meter installation as scheduled to allow overall monitoring throughout the District’s service area. 2. Review customer meter data of high use customers and conduct outreach to determine if demand reduction opportunities exist.

These auxiliary waters may include water from another purveyor’s public potable water supply or any natural source(s) such as a well, spring, river, stream, harbor, or other similar source, or “used waters” or “industrial fluids.” These auxiliary waters may be polluted or contaminated or they may be objectionable and constitute an unacceptable water source over which the District does not have any sanitary control. 1.1.14 “AWWA” shall mean the American Waterworks Association. 1.1.15 “Backflow” shall mean the reverse flow of water or other liquids, gases, mixtures or substances into the distributing pipes of the District’s water supply system from any source or sources other than an intended source. 1.1.16 “Backflow Preventer”, “Backflow Prevention Assembly” is an assembly or means designed to prevent backflow, approved by the District as meeting the current applicable specifications and standards of the University of Southern Cali- fornia’s Foundation for Cross-Connection Control and Hydraulic Research for approved backflow prevention assemblies. Such approved backflow preventers or backflow prevention assemblies include: a) Air-Gap. The unobstructed vertical distance through the free atmosphere between the lowest opening from any pipe or faucet supplying water to a tank, plumbing fixture, or other vessel and the flood level rim of said vessel. An approved air-gap shall be at least double the diameter of the supply pipe, measured vertically, above the top rim of the vessel; and, in no case less than one inch. When an air-gap is used at the service connection to prevent the contamination or pollution of the District’s potable water system, an emergency by-pass shall be installed around the air-gap system and reduced pressure principle assembly shall be installed in the by-pass system. b) Reduced Pressure Principle. An assembly of two independently opera- ting check valves with an automatically operating differential relief valve between the two check valves, tightly closing, resilient seated shut -off 1-3 valves on either side of the check valves, plus properly located test cocks for the testing of the check and relief valves. The assembly shall operate to maintain the pressure in the zone between the two check valves at a level less than the pressure on the District’s water supply side of the device. At cessation of normal flow, the pressure between the two check valves shall be less than the pressure on the public water supply side of the device. In case of leakage of either of the check valves, the differential relief valve shall operate to maintain the reduced pressure in the zone between the check valves by discharging to the atmosphere. When the inlet pressure is two pounds per square inch or less, the relief valve shall open to the atmosphere. To be approved, these assemblies must be readily accessible for in-line maintenance and testing and be installed in a location where no part of the device will be submerged. c) Double Check Valve.

A property owner shall not damage the District’s water system facilities. Any damage caused by the property owner shall be repaired by the District at the property owner’s cost and expense. Section 3.3 Cross Connection Control 3.3.1 District’s Water System. The water system shall be considered to consist of two parts: The District water system and the water user’s system. a) District water system shall consist of the source facilities and the distribution system and shall include the network of conduits used to deliver water and all facilities under the complete control of the District, up to the point where the District’s duty to maintain and repair begins, in accordance with Sections 3.2.2 and 3.2.3. b) The water user’s system shall include those parts of the facilities beyond the termination of the District system which are utilized in conveying water for domestic use. 3.3.2 Policy. No water service connection to any water user shall be installed or maintained by the District unless the water supply is protected, as required by California laws and regulations and this Section 3.3. Service of water to any water user shall be discontinued by the District if a backflow preventer required by this Section 3-21 3.3 is not installed, satisfactorily tested, and maintained, or if it is found that a backflow prevention assembly has been removed, or by-passed, or if an uncontrolled cross- connection exists on the property. Service will not be restored until such conditions or defects are corrected in accordance with Sections 3.3.6 - 3.3.10. 3.3.3 Purpose. The purpose of these provisions regarding cross-connection control is: a) To protect the potable water supply of the District from contamination and pollution by isolating contaminants and pollutants which could backflow or back-siphon into the District’s water system or the water user’s private water system(s). b) To eliminate or control existing or potential cross-connections. c) To systematically and effectively prevent the contamination or pollution of potable water systems. 3.3.4 Responsibility. The District shall be responsible for preventing backflow or back-siphon of contaminants or pollutants through the water service connection. If, in the judgment of the General Manager or other authorized District representative, an approved backflow prevention assembly is required for the protection of the District’s water system at the District’s water service connection to any water user’s property, the General Manager, or other authorized District representative, shall give notice in writing to such water user to install an approved backflow prevention assembly at each service connection to the water user’s property. The water user shall install such approved prevention assembly or assemblies at the water user’s expense within the time schedule required by the notice. Failure, refusal or inability on the part of the water user to install such assembly or assemblies within the time schedule required by the notice shall constitute cause for the imposition of administrative fines and penalties, or discontinuing water service to the property, pursuant to Section 6.5 and Section 6.6, until such assembly or assemblies have been properly installed. 3.3.5 Inspection. At any reasonable time, authorized representatives of the District may inspect the water user’s system to determine whether cross-connections or other structural or sanitary hazards, including violations of any of the Ordinances, rules, and regulations of the District exist. 3.3.6 Backflow Prevention. An approved backflow prevention assembly shall also be installed on each service connection to a water user’s system at or near the property line or immediately inside the building being served; but, in all cases, upstream of the first branch line leading off the service line wherever the following conditions exist: 3-22 a) In the case of a water user having an auxiliary water supply which does, or may contain, pollution or contamination, and which is not approved by the General Manager or other authorized representative. If the water user elects to abandon the auxiliary water supply, the backflow control shall not be required under this Section. b) In the case of property on which any industrial wastes, industrial fluids system or any other pollution or contamination is handled in such a fashion as to create an actual or potential hazard to the District system, including the handling of process waters and waters originating from the District system which have been subject to deterioration in quality. c) In the case of property having (1) cross-connections that cannot be corrected and controlled; (2) intricate plumbing and piping arrangements; or (3) where entry to all portions of the property is not readily accessible for inspection purposes, thereby making it impracticable or impossible to ascertain whether or not cross- connections exist. d) Hydronic Heating Systems. The presence of a hydronic heating system will not be considered a condition requiring the installation of a backflow prevention assembly if the system is a “closed loop system” that is not connection to the potable water system for the provision of make-up water. To be considered a closed loop system, exempt from the backflow prevention assembly requirements, the hydronic heating system must have a stand-alone reservoir for make-up water and a double-walled heat exchanger. To be exempt from the backflow prevention assembly requirements, a hydronic heating system must be approved by a District inspector.” 3.3.7 Type of Backflow Preventer Required. The type of backflow preventer required under subsections 3.3.6 (c) 1, 2, 3 shall depend upon the degree of hazard which exists as follows: a) In the case of any property where there is an auxiliary water supply as stated in Section 3.3.6(a) which is not subject to the provisions of Sections 3.3.7(b) - 3.3.7(f), the District system shall be protected by an air-gap or a reduced pressure principle backflow prevention assembly. b) In the case of any property where there is a pollutional hazard, but not a health hazard, if introduced into the District system, the District system shall be protected by an approved double check valve or a reduced pressure principle backflow prevention assembly. c) In the case of any property where there is any material dangerous to health which is handled in a fashion that creates an actual or potential hazard to the District’s water system, including District fire sprinkler systems, the District’s water system shall be protected by an air-gap or a reduced pressure principle backflow prevention assembly. Examples of property where these conditions will exist include 3-23 sewage treatment plants, tank trucks, mobile water using equipment, sewage pumping stations, chemical manufacturing plants, hospitals, mortuaries, and plating plants. d) In the case of any property where there are uncontrolled cross- connections, the District system shall be protected by an air-gap or a reduced pressure principle backflow prevention assembly at the service connection. e) In the case of any property where, because of security requirements or other prohibitions or restrictions, it is impossible or impractical to make a complete cross-connection inspection, the District’s water system shall be protected against backflow from the property by the installation of a backflow prevention assembly at the service connection. In this case, an air-gap or a reduced pressure principle backflow prevention assembly shall be installed at each service connection to the property. f) In the case of interties with other water purveyors without equivalently controlled cross-connections, such intertie will be removed. 3.3.8 Installation. All backflow prevention assemblies shall be installed according to District specifications which shall incorporate the State of California guidelines, as amended, and the most recent edition of the University of Southern California’s Foundation for Cross-Connection Control and Hydraulic Research’s Manual of Cross-Connection Control. Upon installation of the backflow preventer(s), District Inspectors shall inspect the completed work for compliance with the District’s ordinance and specifications. Copies of these guidelines and manual shall be on file at the District’s Customer Service Office. 3.3.9 Testing. (Reference Ord. No. 556-14.) It shall be the duty of the water user at any property where backflow prevention assemblies are installed to have certified inspections and operational tests performed on such backflow assemblies at least once per year. In circumstances in which the District deems the degree of hazard to be great enough, it may require certified inspections and operational tests at more frequent intervals. These inspections and tests shall be at the expense of the water user and shall be performed by an independent, certified tester as provided by the California Department of Health Services Guidelines. The South Tahoe Public Utility District will only accept backflow certifications from testers that have supplied the District Inspectors Office with copies of their backflow certification and current calibration of equipment. For the purposes of this section, any individual with current California/Nevada Section American Water Works Association General certification , Northern California Backflow Prevention Association or equivalent successor certification, for testing backflow prevention assemblies on file with the District shall be considered a certified tester. The South Tahoe Public Utility District shall revoke the right of the certified tester to test 3-24 backflow prevention assemblies in the District service area, after a hearing before the General Manager, if he/she shall be found to have obtained a certificate by fraud or deceit, or displays negligence, incompetency, misconduct, or misrepresents or falsifies reports in the performance of his/her duties as a Certified Backflow Prevention Assembly Tester. If dissatisfied with the decision of the General Manager, he/she may appeal to the Board by written notice within thirty days. It shall be the duty of the District to see that these inspections and tests are timely made. The water user shall notify the District in advance when the tests are to be undertaken so that the District’s Inspector may observe the inspection and tests if so desired. These backflow prevention assemblies shall be repaired, overhauled or replaced, and retested at the expense of the water user whenever they are determined by the District Inspector to be defective, improperly installed or improperly located. Records of inspections and tests, replacement parts, repairs, overhaul and relocation shall be kept by the water user and made available to the District, the El Dorado County Health Department, the owner of the backflow prevention assembly, and the District or independent inspector. All repair and replacement parts shall be equal in quality to those supplied by the manufacturer of the backflow prevention assembly being repaired or replaced. No backflow prevention assembly may be altered in any way from its manufacturer’s design, material, or operational characteristics. 3.3.10 Existing Backflow Prevention Assemblies. All existing backflow prevention assemblies which do not meet the requirements of this Section 3.3, but were approved when installed and which have been properly maintained shall, except for the inspection and testing requirements under Section 3.3.9, be excluded from the requirements of the Ordinances, rules, and regulations of the District so long as the District has determined that they will satisfactorily protect the District’s system. Whenever an existing backflow prevention assembly is moved from its location , requires more than minimum maintenance, or when the District finds that its maintenance constitutes a health hazard, the unit shall be replaced by a backflow prevention assembly meeting the requirements of the Ordinances, rules, and regulations of the District.

Ord. 500-07) 3.5.1 Policy and Purpose. The purpose of this Section 3.5 is to regulate, manage, conserve and protect the District’s ongoing water supply in such a manner that the District’s water supply, including but not limited to the groundwater resources within the boundaries of the District, will remain a viable resource to be put to the most efficient and beneficial use by the District and its inhabitants, while also safeguarding the health and safety of the District’s inhabitants. The District is responsible for managing the groundwater within its boundaries and is dedicated to preserving the quantity and quality of its groundwater resources. 3-31 In response to declining groundwater levels within the District’s boundaries, the District intends to authorize District water service to persons who are currently utilizing wells on their property for domestic uses and are experiencing a loss in their well production and/or deteriorating water quality. The District is aware that many factors can cause or contribute to a loss of production and/or deteriorating water quality in wells including declining water levels associated with droughts, or mechanical problems, age or construction design of the well. Matter of District policy the District desires to offer these well owners District water service as a reliable and cost effective source of supply to mitigate any potential adverse effects, which may be attributable to declining groundwater levels. 3.5.2 Authorization of District Service. The District shall provide requested water service under reasonable terms and conditions through the District’s water distribution system to persons who are currently utilizing and extraction facility on their property for the extraction of groundwater for domestic uses in identified areas of potential declining groundwater levels and who are experiencing, or have experience, a loss of production and/or deterioration in water quality in their wells at any time duri ng the period from July 19, 2007 to July 19. 2015 and who make a showing that 1) their existing wells which have been in operation on or after July 19, 2007, are located within the radius of influence of the District’s Municipal Wells; and 2) the loss of production and/or deterioration in water quality was caused or contributed to by the groundwater extraction activities of the District. The District shall have the right to enter upon any property at any reasonable time to make examinations for the purpose of verification of loss of production and/or deterioration in water quality, subject to the provisions of Code of Civil Procedure section 1822.50, et. seq. The District may subsequently revise and extend this time period based upon the results of hydrogeologic studies and investigations prepared by, or on behalf or, the District. The District shall provide the requested water service to these private well owners’ subject property of comparable quantity and quality in accordance with the District’s rules and regulations. The District shall provide requested water service to these private wells owners’ subject property at no cost to the owner of the subject property for the No-Cost Service Period following the date of connection to the District’s water distribution system. The No-Cost Service Period shall be determined on a property-by-property basis and shall be equivalent to the difference between 50 years and the age of the extraction facility, in years, in existence on the Subject Property as of July 19, 2007. Thereafter, the District shall charge the owner of the Subject Property the then prevailing rate for District water service as provided in the applicable District rules and regulations. Alternatively, the Property owner may elect that the District establish a five thousand dollar ($5,000) credit for water service to the subject property. The District has determined that, with 3-32 the incorporation of the No Cost Service Period or a water service credit, the property owner’s costs of receiving water service from the District over the remaining useful life of the extraction facility on his or her property are comparable to the cost to the property owner of extracting groundwater for domestic uses from an extraction facility on his or her property. 3.5.3 Connection Fees and Costs; Contents, Decision.

If a stoppage is not found in the main line but is found in the portion of the sewer lateral between the main line and the foundation of any wall, the owner shall be notified that the clearing of the stoppage or clean-up of the spill shall be the responsibility of the owner. If the stoppage is proven to be caused by faulty pipe installation or faulty pipe of the sewer lateral line between the main line and the nearer property line, the District will pay for the repairs. 4.7.6 Emergency Repairs by District. Whenever, in the judgment of the District Inspector, immediate repairs, clean up, or other activities must be performed to a sewer lateral in order to preserve public health or to prevent damage or injury to the District sewer, the District Inspector may, without notice to the property owner, cause such repairs, clean up or other activities to be performed and may contract with a private contractor for such purposes or may perform such repairs, clean up or other activities with District personnel. 4.7.7 Reimbursement of District. The property owner serviced by a sewer lateral shall reimburse the District for the costs of all repairs, clean up or other activities, made or contracted for by the District pursuant to Section 4.7.6.

Section 4.8 Sewer Capacity. 4.8.1 Schedule of Sewer Units. The schedule of sewer units, as established in Section 4.5.6, shall be applicable to this Section 4.8. 4.8.2 Current Equity. The present estimated capacity within the District’s service area is Eighty-Six Thousand Seven Hundred Two (86,702) sewer units. The present sewer fund equity, after deduction for accumulated depreciation of the fixed assets of the District, is approximately One Hundred Eleven Million Seven Hundred Thirteen Thousand Eighty-One Dollars ($111,713,081), which is approximately One Thousand Two Hundred Eighty-Eight Dollars ($1,288) per sewer unit. 4.8.3 Rate Relief for Excess Sewer Units. On a form provided by the District, the owner of a parcel with Excess Sewer Units may apply to the District to participate in the Excess Sewer Capacity Program for the relief of service charges for Excess Sewer Units. The applicant requesting such rate relief shall allow the District full and adequate inspection of the parcel, including any improvements, and the sewer lines and related connection to enable the District to determine if the parcel has any Excess Sewer Units. The applicant may be required to test or remove underground piping, draining lines or the sewer lateral for verification of the sewer capacity required on the parcel and that all fixtures on the parcel are low water-use fixtures. Upon a property owner’s application to the District for participation in the Excess Sewer Capacity Program, the billing of sewer service charges will be suspended on any Excess Sewer Units until such time as they are transferred, pursuant to Administrative Code Section 4.8.14, or put into use on the same parcel. The adjusted service charge, reflecting the suspension of charges on any Excess Sewer Units, shall be effective for the first complete billing cycle after the date of the District’s approval of the application and verification of any Excess Sewer Units on the same parcel. A property owner with verified Excess Sewer Capacity will receive a credit for any service charges associated with the verified Excess Sewer Capacity in an amount equal to any suspended sewer service charges for Excess Sewer Capacity. Excess Sewer Units may be transferred to another parcel, pursuant to Administrative Code Section 4.8.14, or may be later used on the same parcel. The owner of a parcel with Excess Sewer Units may acquire sewer capacity, in addition to those units but only in the same manner, with the same priority, and subject to payment of the same fees, as any other parcel which might need to obtain additional sewer capacity, and only if the District has available sewer capacity at the time the owner requests the additional sewer service. (Reference Ord. 584-22) 4-25 4.8.4 Authority. No sewer capacity shall be issued which does not comply with the criteria set forth in this Section 4.8 or which would violate any law, including any order or judgment of a court of competent jurisdiction or the orders of competent governmental authorities, including the waste discharge orders of the California Regional Water Quality Control Board - Lahontan Region. 4.8.5 Inspection. Inspection of existing or new sewer piping, as provided in Section 4.4.10, may be required. 4.8.6 Existing Demand. When available estimates indicate that existing sewer capacity demand will exceed the sewer capacity available for issuance at the rate established by this Section 4.8, no further Change in Use sewer capacity shall be issued except upon action of the Board. Notwithstanding any of the provisions of this Section 4.8.7, the issuance of Change in Use sewer capacity shall be limited as provided in Sections 4.8.8, 4.8.9 and 4.8.16. 4.8.7 Application. Application for Change in Use sewer capacity shall be made on a form provided by the District and shall include complete plans and specifications for the contemplated work of improvement for which such sewer capacity is desired. The application shall not be deemed complete or received by the District unless and until it is accompanied by such plans and specifications. 4.8.9 Attributes. Attributes existing on developed property have been treated as additional, subordinate rights or privileges of that property and, depending upon whether such attributes were lawfully created, were permitted to continue.

The Tahoe Regional Planning Agency, the City, and the County permit certain transfers of various attributes and the right to attributes from one property to another in accordance with the Amended Regional Plan for the Lake Tahoe Basin, including the “Growth Management Provisions” of its Code of Ordinances and local government codes. 4.8.11 Transfer of Sewer Capacity. Sewer capacity rights are and have been appurtenant to and inseparable from property. In order to accommodate the transfer programs of the Tahoe Regional Planning Agency, the City, and the County, the District has adopted rules and regulations from time to time regarding proposed transfer of the 4-26 right to discharge into the collection, treatment, and export facilities of the District. 4.8.12 Transfer of Equity. District’s existing customers have an equity credit equal to One Thousand Two Hundred Eighty-Eight dollars ($1,288.00) per sewer unit which may be used toward the current connection fees when transferring capacity rights. 4.8.13 Costs of Transferring Sewer Capacity. It is necessary and appropriate that the cost of transferring sewer capacity rights be paid by those who request such transfers to occur. 4.8.14 Conditions to Transfer. (Reference Ord. No. 578-20.) Transfer of Excess Sewer Units shall be allowed only: (1) for the development of Affordable Housing and no sewer permit shall be issued for development of Affordable Housing on a Primary Parcel when Excess Sewer Units are transferred from a Secondary Parcel; and (2) from a Secondary Parcel to a Primary Parcel provided both parcels are owned by the same Public Agency.
