7.2.3 WSRA DESCRIPTION OF MANAGEMENT TOOLS AND OPTIONS TO MAINTAIN

RELIABILITY
SBUA agencies have several ongoing and planned demand management projects and programs. These are summarized in Chapter 9. Public outreach and education, coupled with demand reduction programming like rebates and home surveys, can decrease long-term demand, increase reliability, and minimize the need to import water from other regions.

In times of water shortage, water demand restrictions can be implemented by enacting the WSCP, outlined in Chapter 8. The restrictions largely focus on decreasing water use for outdoor irrigation.

Additionally, in times of serious water shortage, a larger portion of water can be derived from groundwater to meet demands.

Section 6.2.10 describes future water projects Including potential surface water storage expansion, expanded managed aquifer recharge, and additional well production capacity in conjunction with increased groundwater monitoring.

7.3 DROUGHT RISK ASSESSMENT
While Section 7.2 evaluates long-range supply reliability, this section presents the drought risk assessment (DRA) in accordance with Water Code Section 10612, which focuses on near -term shortage preparedness during the next five years. The DRA reliability assessment involves characterizing the expected quantity of each water supply source monthly for each year of the five-year drought under a variety of water shortage conditions. For purposes of the analysis, the drought is assumed to occur in the next five years.

For planning purposes, the representative five-year drought selected for the DRA was 2012-2016 because it combined low precipitation with historically low CVP allocations to the SBUA.

The analysis also addresses the reliability of water sources expected to be used during water supply shortages, which are not part of the Supplier's normal water portfolio (e.g., special transfer or exchange agreements). The analysis reveals potential shortage or surplus; if a shortage is indicated, WSCP demand reduction measures and supply augmentation are identified to resolve the shortage. DWR recommends that the DRA address possible scenarios that could further impact water supply such as climate change.

Recent critically dry year allocations and Public Health and Safety approvals support a planning assumption of approximately 33 percent minimum availability during severe drought, although future allocations are not guaranteed.

The DRA has been developed using the Planning Tool provided by DWR. The Planning Tool DRA Worksheets are summarized in Table 7-5. Table 7-5 summarizes annual projected supplies, demands, shortages, and response actions for each year of the five-year drought scenario. The SBUA agencies reviewed their supply and demand deficit on an annual basis, as imported water allocations are the biggest uncertainty year to year. They did not examine the demand and supply on a monthly time scale as they rely on local storage (San Justo and San Luis Reservoirs) to help meet the peak demands in the

RIMMAMMUMWARNMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUMMAMMUM San Benito Urban Areas UWMP 2025

summer months. Because of the surface storage and the stable groundwater conditions, the agencies are able to dynamically adjust supply to meet demand throughout the year.

7.3.1 DATA, METHODS, AND BASIS FOR WATER SHORTAGE CONDITIONS The data used to complete the DRA are documented in this UWMP as are assumptions on future growth.

A linear extrapolation was used to account for annual growth over the next five years, 3.5 percent per year (as used in the 2023 Master Plan). The reliability of water supply sources is documented in Section

7.2.3. For the DRA, it was assumed that the voluntary Stage 1 of the WSCP would be applied for the first two dry years, reducing total demand by 10 percent. After the first two years, Stage 2 of the WSCP would be implemented to save up to 20 percent of demand.

The water supply is projected to remain relatively stable during the five-year drought, as increased groundwater use and CVP supplemental water compensate for reduced CVP deliveries. As discussed in

7.2.3, CVP allocations are reduced in drought periods. However, local groundwater is managed to account for increased pumping in times of water shortage, although its use may be managed to maintain high delivered water quality.

The maximum annual supplies for 2012-2016 drought conditions were calculated and compared to the demand to determine sufficiency. When demand exceeded supply, the difference was compared to the total demand. The annual demand exceeds 110 percent of the maximum annual supply available after the first two years. Stage 2 of the WSCP, with mandatory actions, is expected to sufficiently reduce demands.

Some sources of error and uncertainty affect this DRA. Dry conditions may lead to an increase in irrigation.

However, it is generally expected that outreach and education, especially with up-to-date use of news media (Quesnel and Ajami, 2017), will result in residential water use decreases. Timing of water use may vary during dry periods, and water users may respond more quickly to drought conditions than during the 2012-2016 drought years. Notwithstanding some uncertainty, if voluntary restrictions in WSCP Stage 1 do not cause a timely 10 percent decrease in demand, Stage 2 or greater can be implemented at any time.

7.3.2. INDIVIDUAL WATER SOURCE RELIABILITY
Table 7-C summarizes the expected reliability of each major water supply source available to the SBUA during the five-year drought planning period evaluated in this DRA. The table identifies the relative availability, operational role, and key constraints associated with imported CVP water, groundwater, recycled water, and supplemental stored or transferred supplies under shortage conditions. The SBUA's diversified supply portfolio reduces dependence on any single source and allows available supplies to be managed conjunctively in response to changing hydrologic, regulatory, and demand conditions. The individual source descriptions below provide additional detailed availability and reliability during the drought period.

CVP ALLOCATIO
The SBUA relies primarily on groundwater and CVP imported water, with some use of recycled water.

Both groundwater and CVP supplies are impacted during dry years.

Table 7-1 W shows the supply reliability of CVP imported water for the District. Tables 7-1 CVP, 7-1 Groundwater, 7-1 CVP Supplemental and 7-1 Recycled Water Retail show the retailer supply reliability of CVP imported water, groundwater, and recycled water based on the different year types.

Table 7-1 W estimates the reduction in CVP for single and multiple year droughts based on past allocations. As discussed in Section 6, past allocations were used to project future availability. It is estimated that the future average allocation will be 75 percent of the contract in normal years, amounting to 6,188 AFY for the District (0.75 x 8,250 AFY). The SBUA retailers could receive 5,988 AFY, while the remaining volume is served by the District to other M&I users (200 AFY) or is accounted by 10 percent system losses. CVP supply allocations are reported by the San Luis & Delta -Mendota Water Authority (SLDMWA) for the USBR water year (March through February).

The US Bureau of Reclamation published a Municipal and Industrial Water Shortage Policy and Environmental Impact Statement for the Central Valley Project in August 2015 (USBR 2015). The M&I shortage policy recognizes that CVP M&I water is needed to meet Public Health and Safety (PHS) needs; nonetheless, USBR cannot guarantee allocation.

In 2022, for M&I users, the initial allocation was also 0 percent but agencies had the opportunity to request water to serve public health and safety (PHS) needs. The District prepared a memorandum to USBR summarizing the demands and supplies of the retailers consistent with the "Central Valley Project Municipal and Industrial Water Shortage Policy Guidelines and Procedures" (WSP Guidelines). The District documented that —without any CVP imports —the unmet PHS demand would be 2,968 AF. USBR granted the District 2,766 AF, equivalent to 33.5 percent of their contract. For future critically dry years, the SBUA anticipates this would be the minimum allocation.

RIMMAMMEUMEUMEMEWARMAMMEURREUMETAMARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEURREM San Benito Urban Areas UWMP 2025 Page 7-13

Future CVP projections are based on the actual allocations since 2007. The allocations are more conservative than the previous estimates available from Cal Sim II, a DWR tool used to simulate California SWP/ CVP operations. The expected M&I allocations by water year type are shown by base year in Table 7-1 CVP for the retailers and Table 7-1 W.

The District plans to supply approximately 200 AFY to M&I customers other than the City of Hollister and Sunnyslope. This additional M&I demand will be met during normal years, a single dry year, or the first year of a multiple year drought. In the event of a prolonged drought, the non -urban portion of this demand (200 AFY) may be unmet in order to provide the minimum human health and safety for urban residents.

GROUN WATER
The volume of groundwater used by the SBUA is linked to the CVP allocation because local users prefer the higher quality CVP water. Accordingly, all of the CVP allocation is expected to be used by Hollister, Sunnyslope, and SJB with groundwater as a supplemental source. The groundwater basin is managed for continued sustainability, as documented in the GSP, and for provision of supplemental supply during drought. Accordingly, Table 7-1 Groundwater shows no decrease of availability during drought conditions.

In Table 7-1 Groundwater, the volume of available groundwater is not reduced from the sustainable yield of 6,250 AFY (discussed in Section 6). This is a conservative estimate, while long term pumping should not exceed the sustainable yield, short term pumping may exceed this volume if needed during continued dry years.

Table 7-1 Groundwater accounts for the preferred blending of groundwater with CVP supply (targeting 20 percent) to improve delivered water quality. Additional groundwater may be used during drought conditions.

RECYCLED WATER
The annual rate of recycled water is based on the 2025 value of 80 AF. Recycled water is not reduced in Table 7-1 Recycled Water because the source is reliable and not affected significantly by year-to-year hydrological variability. However, its desirability as a supply for some sensitive uses could be affected by changes in municipal water quality. For example, a significant long-term increase of groundwater use (for example, due to low CVP allocation and assuming no wellhead demineralization) could affect wastewater quality and thus the quality of the recycled water.

RESERVOIR STORAGE AND SUPPLEMENTAL WATER
The District manages San Justo Reservoir as storage for imported CVP water. In times of full allocation, the District is able to purchase additional water to keep as a reserve for future dry years. The District plans to reserve sufficient water to provide up to an additional 1,000 AFY for a limited time during the most severe droughts for up to five years. In addition, ADRoP, described in Section 6, will supply CVP water during dry years. The project will store surplus CVP water and deliver up to 6,000 AFY. As the project is only replenished during wet years, it is assumed the maximum volume of 6,000 AF would be available

RIMMAMMUMMUARMARMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARM San Benito Urban Areas UWMP 2025

over the course of a multi -year drought, delivered as 1,000 AFY for each year of the drought up through six years. The combined amount of 2,000 AF is documented in Table 7-1 CVP Supplemental.

WATER SHORTAGE CONTINGENCY PLAN
As experienced in the most recent drought, water conservation can reduce demand effectively. Chapter 8 of this UWMP outlines the Water Shortage Contingency Plan (WSCP), which contains voluntary and mandatory restrictions to curb demand by 10, 20, 30, 40, 50, and greater than 50 percent in times of water shortage. The WSCP also discusses outreach and education programs to decrease demand and temporary actions to augment water supply.

7.3.3 TOTAL WATER SUPPLY AND USE COMPARISON
Table 7-5 summarizes monthly projected supplies, demands, shortages, and response actions for each year of the five-year drought scenario. As indicated, the SBUA is prepared for a multiple year drought given the availability of a portfolio of sources and active management of potential risks. While necessary to long-term basin sustainability, CVP supply is considered less reliable, given that M&I allocations can range from 33 to 100 percent and local agencies have little control. However, the SBUA actively seeks out additional contracts and transfers and stores the additional supply in San Justo reservoir in preparation of multi -year droughts. Currently, the District is capable of continuing to provide adequate CVP supplies to the SBUA even in a multi -year drought. In addition, the District manages the groundwater basin conjunctively with surface water supplies, providing a reliable supply in the event of CVP interruption.

The current DRA projections indicate that the SBUA can withstand a five-year drought beginning in 2026 with implementation of only stage 1 of the WSCP, a voluntary 10 percent reduction to bridge the gap between supply and demand. However, if voluntary measures do not result in the expected 10 percent demand reduction, the SBUA agencies will be prepared to implement Stage 2 mandatory restrictions.

The SBUA relies primarily on groundwater and CVP imported water, with some use of recycled water.

Both groundwater and CVP supplies are impacted during dry years. Tables 7-1 Retail show the available supply for the agencies for normal, single dry, and multiple dry years for each water source. The available supply is based on forecasts for each source.

NOTES:

The District, Hollister, Sunnyslope, and SJB have all passed ordinances/resolutions to address shortages in water supply. In addition, the SBUA agencies have updated the Water Shortage Contingency Plan (WSCP).

This plan serves as a guide for adjusting supply and demand in response to a water shortage. The original plan was developed in 2016 as part of the 2015 Urban Water Management Plan (Appendix D) and provides details on how to reduce demand in the event of a water supply shortage.

In response to the 2012-2016 drought, a new WSCP mandate requires WSCPs to provide a more detailed analysis of supply and demand contingency actions and plan implementation. Additions to the 2020 WSCP include the documentation of plan procedures and implementation, standardization of water supply stages of action for the water supply plan, and quantification of contingency action effects on supply and demand.

Emergency responses to natural disasters are also discussed in a joint Water Shortage Emergency Response Plan to assist in planning and managing supply disruption, Appendix E.

The 2016 WSCP outlined a water shortage response plan in the event of supply interruption. This plan included a four -stage rationing plan with voluntary and mandatory rationing depending on the severity and duration of the water supply shortage. The water shortage response was based on the Sunnyslope No Water Waste Ordinance No. 45 and was first documented for the HUA (now SBUA) as part of the 2000 UWMP.

Pursuant to Water Code Section 10632(a)(3), all WSCPs must include a six -stage plan corresponding to shortage stages of up to 10 percent, 20 percent, 30 percent, 40 percent, 50 percent, and greater than 50 percent of water supply. During the 2012-2016 drought years, differences in state and local definitions led to uncertainty in public communication and state policy. This standardization is meant to aid communication and response action implementations across the state.

Water Code Section 10632(a)(3)(B) allows suppliers to retain existing water shortage response plan stages if the existing stages are directly related to the specified six stages. The four stages identified in the previous 2016 WSCP have been translated to the six new stages, which are shown in Table 8-1. For the new Stage 1, up to 10 percent reduction, the voluntary measures for the previous stage 1 (up to 15 percent) are applicable. For both 10 to 20 percent and 20 to 30 percent reductions, the previous Stage 2 restrictions are applicable, aiming for 25 percent reduction. For 30 to 40 percent and 40-50 percent reductions, the previous Stage 3 is applicable, which aims for 35 percent reductions. Finally, for greater than 50 percent reductions, the previous Stage 4, is applicable for over 50 percent reduction.

8.1 WATER SYSTEM RELIABILITY ANALYSIS
Water supply reliability analyses conducted by the SBUA (Section 7) identify constraints on water supply sources and evaluated each source's availability during a normal year, a single dry year, a five-year drought period, and twenty-year future projections. These analyses show that supply resources are sufficient to hOPSIRMAMMVWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWM San Benito Urban Areas UWMP 2025 Page 8-1

meet demand. The SBUA depends on imported water, groundwater, and recycled water to meet its supply.

CVP water has been imported by the District for direct municipal supply since 2003 and water treatment facilities have been expanded to an operational capacity of 6,720 AFY, 81 percent of the total contractual allocation for CVP M&I water (8,250 AFY). However, allocations vary based on hydrologic conditions. The CVP allocation for M&I demand since 2006 has ranged from 0 percent (public health and safety) during dry years, to the full allocation during wet years.

In 2022, For M&I users, the initial allocation was also 0 percent, but agencies had the opportunity to request water to serve public health and safety (PHS) needs. The District prepared a memorandum to USBR summarizing the demands and supplies of the retailers consistent with the "Central Valley Project Municipal and Industrial Water Shortage Policy Guidelines and Procedures" (WSP Guidelines). The District documented that —without any CVP imports —the unmet PHS demand would be 2,968 AF. USBR granted the District 2,766 AF, equivalent to 33.5 percent of their contract. For future critically dry years, the SBUA anticipates this would be the minimum allocation, although USBR does not guarantee any future allocations.

In 2025, the total CVP water supply for the SBUA was 4,176 AF, not including losses. Future projections suggest an average of 75 percent of CVP supplies in normal years, resulting in 7,425 AFY for supply in the SBUA.

The groundwater basin provides critical storage and is also an important source of water for Hollister, Sunnyslope, and SJB which pump groundwater directly from wells within the SBUA. As documented in the GSP, the groundwater basin is managed sustainably, and stored groundwater is replenished in wet years for use in dry years. While groundwater has relatively poor water quality, it is blended with CVP supply in order to improve water supply, and indirectly the quality of wastewater and recycled water.

Recycled water is used at Riverside Park in the SBUA but has been prioritized for agricultural users outside the SBUA. No surface or stormwater are utilized directly for supply, but these sources of water can be used to supplement recharge.

Drought is the primary issue that would cause a shortage condition. Other causes of a water shortage include the sudden presence of unforeseen toxins or infrastructure damage due to earthquakes or other natural disasters.

The Water Supply Reliability Analysis shows that the current available supply is sufficient to meet unconstrained demand during both a regular year and a single dry year (Section 7.2.2.2). Accounting for growth, the water supply during a normal year would meet demand every year 2020-2040. During a single dry year, supply would decrease due to decreased CVP allocations but can be supplemented with groundwater and other sources or addressed with conservation. The current supply is sufficient to meet unconstrained demand in 2025, 2030, and 2035, but demand in 2040 is expected to be 186 AF greater than supply (i.e., 1.3 percent of the total 10,859 AF projected demand). Initiation of voluntary Stage 1 of the WSCP is recommended during dry years.

RIMMAMMEUMEUMEMEWARMAMMEURREUMETAMARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEURREM San Benito Urban Areas UWMP 2025 Page 8-2

The Drought Risk Assessment evaluates if current supplies are sufficient to meet demand during a multi- year drought. In brief, the maximum available supply was found sufficient to meet demand for three out of five dry years. The dry year conditions were based on the 2012-2016 drought years, and water demands were adjusted for population growth over the next five years. Although the supply should be sufficient to meet demand during the first three years of a multi -year drought, it is recommended that the SBUA Agencies implement the voluntary WSCP Stage 1 as a precautionary measure to conserve water during every drought year. After year two of a multi -year drought, the projected demand was greater than the maximum supplies if Stage 1 if the WSCP was not implemented. The gap each year was less than 20 percent of total demand, and it is expected that implementing Stage 2 of the WSCP would bridge the gap.

However, agencies should be prepared to implement higher stages in the event of extended dry years.

8.2 ANNUAL WATER SUPPLY AND DEMAND ASSESSMENT PROCEDURES Beginning in 2022, SBUA agencies have prepared and submitted an annual water supply and demand assessment, pursuant to section 10632 (a)(2) of the Water Code. These annual assessments must be submitted to DWR by July 1 of each year.

The annual assessment has been completed in conjunction with the SGMA North San Benito County Groundwater Sustainability Agency annual GSP report. SGMA requires the submittal of this annual report on April 1. The GSP annual report includes analyses of recent groundwater conditions, surface water supply, total water use, and change in groundwater storage. In addition, the report summarizes supply and demand in the previous water year and includes an estimate of next -year conditions, agricultural pumping, and water purchases. The water supply and demand assessments for the SBUA are prepared as a follow up memo relaying the same data as the annual report to streamline data requests and reporting for the three agencies.

The assessment will include documentation of the projected supply and demand for the upcoming year and determination that supply will be sufficient, even during a dry year. Supplies, including available groundwater, CVP, and recycled water, will be assessed by describing and quantifying the previous year's water supply and estimating the upcoming year's supplies. Groundwater use and basin conditions in the previous water year were assessed to determine any issues. The supply assessment includes data on climatic conditions, groundwater levels and extraction, land use, streamflow measurements, reservoir budgets, CVP deliveries, recharge rates, municipal recycling rates, and water quality data. The demand assessment relies on agency -reported totals by use category.

Projected supplies are largely dependent on climate and water conditions during the previous water year and the projected CVP allocations. In the annual water supply and demand assessment, the supplies are assessed for both the current year and the subsequent dry year, taking plausible constraints into account.

Unconstrained customer demand is assessed annually by looking at historical growth, climate, and water demand over the previous water year. The previous year's use was adjusted to account for new customer connections. If the planned use is greater than the dry year supply, the SBUA agencies are prepared to

enact the WSCP. Any infrastructure projects or conditions will also be factored into the supply and demand assessment.

8.3 WATER SHORTAGE LEVEL STAGES OF ACTION
Pursuant to Water Code Section 10632(a)(3), all WSCPs must include a six -stage plan corresponding to shortage stages of up to 10 percent, 20 percent, 30 percent, 40 percent, 50 percent, and greater than 50 percent of water supply. During the 2012-2016 drought years, differences in state and local definitions led to uncertainty in public communication and state policy. This standardization is meant to aid communication and response action implementations across the state.

Water Code Section 10632(a)(3)(B) allows suppliers to retain existing water shortage response plan stages if the existing stages are directly related to the specified six stages.

8.4 SHORTAGE RESPONSE ACTIONS
Water shortages can be met by augmenting the supply and/or decreasing the water demand. Each response action must be implementable. In Sections 8.4.1 and 8.4.2, the response actions for each stage are outlined, along with the methodology for calculating action effectiveness. Tables 8-2 R and W present the two general demand reduction actions (namely, to increase the proportion of groundwater in potable water, and to use imported water stored in San Justo Reservoir for drought reserves), the stages in which they are implemented, and the estimated percent by which they can decrease demand. Tables 8-3 R and W provide detailed lists of demand reduction actions.

In response to the WSCP guidelines, the effectiveness of each demand reduction action has been quantified for SBUA using the best available data. It should be noted that the effectiveness of many shortage response actions has not been studied, and effectiveness can vary by region. These estimates are best used as guidelines to inform decision makers about which actions may contribute most to demand reductions. The methods for calculating the effectiveness of each action are outlined in Appendix F. In addition to the methods outlined as part of the WSCP, further demand reductions (particularly with indoor residential water use) are expected due to outreach, education, and social pressures.

The effectiveness of each action was estimated based on the observed water demand reduction during the 2014-2016 drought, studies and literature reviews examining the effectiveness of individual and combined response actions, and calculations of demand decreases scaled to the regional population.

These estimates reflect best available data; however, it should be noted that the estimates are also uncertain. Historical data on demand reductions during drought, both within SBUA and in case studies, are a result of combined demand restrictions, public education, and social pressures. There are very few studies of the effect of individual actions. In addition, a variety of assumptions are used in calculations of water demand as reduced by a given action. For example, estimating the money saved by restricting at- home carwashes involved assumptions about how many SBUA residents would wash their car at home in a non -drought month, how many of those carwashes would use a hose with a nozzle, and how much water each wash would use. Furthermore, several restrictions rely on postponing actions or implementing large

RIMMAMMEUMEUMEMEWARMAMMEURREUMETAMARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEURREM San Benito Urban Areas UWMP 2025 Page 8-4

water -use projects, such as filling up a new pool, removing a single -pass cooling system, or receiving a large new water permit.

8.4.1 LOCALLY APPROPRIATE DEMAND REDUCTION BY STAGE
Implementation of restrictions and prohibitions on end users is based on a fundamental prioritization of domestic supply for human health and safety over non -essential uses, including landscape irrigation. In the event of a water shortage, water service may be restricted or prohibited for non -essential uses, recognizing that certain end users may be required to save more water than others because of their specific use. Prohibitions on end uses will affect user types differently:
• For urban residential users (who typically rely on SBUA agencies for domestic supply), water service will continue during a shortage with restrictions on outdoor water use in Stages 1 through 5 and prohibitions in Stage 6.
• Rural residential users of CVP M&I water would also be subject to restrictions and prohibitions on outside water features and landscape irrigation. • Landscape irrigators (e.g., golf courses, dedicated irrigation meters) are subject to the restrictions listed below for Stages 1 through 5 and the prohibition in Stage 6. • Commercial businesses are subject to all restrictions in Stages 1 through 5 and prohibitions in Stage 6.

Stage 1
The first stage applies voluntary actions to reach the demand reduction goal of 10 percent, with a focus on outdoor irrigation demand reduction.

1. Recommended Watering Hours: Watering or irrigating of lawn, landscape or other vegetated area with potable water is discouraged between the hours of 9:00 a.m. and 5:00 p.m. Pacific Standard/Daylight Savings Time.

Recommended Limit on Watering Duration: Watering or irrigating of lawn, landscape or other vegetated areas with potable water using a landscape irrigation system or a watering device that is not continuously attended is recommended to be limited to no more than three days a week with a duration of fifteen minutes watering per water day per station. This subsection does not apply to landscape irrigation systems that exclusively use very low -flow drip type irrigation systems when no emitter produces more than two gallons of water per hour and weather -based controllers or stream rotor sprinklers that meet a 70 percent efficiency standard. The use of recycled water is exempt from this prohibition.

3. Eliminate Excessive Water Flow or Runoff: Watering or irrigating of any lawn, landscape or other vegetated area in a manner that causes or allows excessive water flow or runoff onto an adjoining sidewalk, driveway, street, alley, gutter, or ditch is strongly discouraged.

4. Discourage Washing Down Hard or Paved Surfaces: Washing down hard or paved surfaces, including but not limited to sidewalks, walkways, driveways, parking areas, tennis courts, patios or alleys, is discouraged except by use of a hand-held bucket or similar container, a hand-held

6. Recirculating Water for Water Fountains and Decorative Water Features: Operating a water fountain or other decorative water features that uses recirculated water is encouraged.

7. Washing Vehicles: Using water to wash or clean a vehicle, including but not limited to any automobile, truck, van, bus, motorcycle, boat, or trailer, whether motorized or not is discouraged, except by use of a hand-held bucket or similar container or a hand-held hose equipped with a positive self -closing water shut-off nozzle or device. Washing vehicles at commercial conveyor car wash systems with re -circulating water systems is recommended.

8. Drinking Water Served Upon Request: Eating or drinking establishments, including but not limited to a restaurant, hotel, cafe, cafeteria, bar, or other public place where food or drinks are sold, served, or offered for sale, are encouraged to providing drinking water to any person only when expressly requested.

9. Commercial Lodging Establishments Encouraged to Provide Guests Option to Decline Daily Linen Services: Hotels, motels and other commercial lodging establishments are encouraged to provide customers the option of not having towels and linen laundered daily. Commercial lodging establishments are encouraged to prominently display notice of this option in each bathroom using clear and easily understood language.

3. Installation of Single Pass Cooling Systems: Installation of single pass cooling systems is discouraged in buildings requesting new water service.

10. Installation of Non -recirculating Water System in Commercial Car Wash and Laundry Systems:

Installation of non -recirculating water systems is discouraged in new commercial conveyor car wash and new commercial laundry systems.

11. Restaurants Encouraged to Use Water Conserving Dishwash Spray Valves: Food preparation establishments, such as restaurants or cafes, are encouraged to use water conserving dish wash spray valves.

12. Commercial Car Wash Systems: All commercial conveyor car wash systems are encouraged to install operational re -circulating water systems.

13. Pool Covers: It is recommended that all existing pools use a pool cover or solar blanket to reduce water loss due to evaporation.

Stage 2
The second stage seeks a 10 to 20 percent reduction of future supplies, and uses restricted building permits, mandatory rationing, and reduction by customer types. The shortage response actions in Stage 2 are derived from the 25 percent reduction stage established in the 2016 WSCP. Stage 2 continues the voluntary reductions in Stage 1. In addition, the following reduction requirements become mandatory:

4. Limits on Watering Hours: Watering or irrigating of lawn, landscape or other vegetated area with potable water is prohibited between the hours of 9:00 a.m. and 5:00 p.m. Pacific Standard/Daylight Savings Time on any day, except by use of a hand-held bucket or similar container, a hand-held hose equipped with a positive self -closing water shut-off nozzle or device, or for very short periods of time for the express purpose of adjusting or repairing an irrigation system. The use of recycled water is exempt from this prohibition.

5. Limit on Watering Duration: Watering or irrigating of lawn, landscape or other vegetated area with potable water using a landscape irrigation system or a watering device that is not continuously attended is limited to no more than fifteen minutes watering per designated water day per station. This subsection does not apply to landscape irrigation systems that exclusively use very low -flow drip type irrigation systems when no emitter produces more than two gallons of water per hour and weather based controllers or stream rotor sprinklers that meet a 70 percent efficiency standard. The use of recycled water is exempt from this prohibition.

6. Limits on Watering Days: Watering or irrigating of lawn, landscape or other vegetated area with potable water is limited to three days per week from April through October. The watering days are designated depending upon house address (odd house and no house address Monday, Wednesday, and Friday, even house address Tuesday, Thursday, and Saturday). During the months of November through March, watering or irrigating of lawn, landscape or other vegetated area with potable water is limited to no more than one day per week (odd house and no house address - Monday, even house address - Tuesday). This provision does not apply to landscape irrigation zones that exclusively use very low flow drip type irrigation systems when no emitter produces more than two (2) gallons of water per hour. This provision also does not apply to watering or irrigating by use of a hand-held bucket or similar container, a hand-held hose equipped with a positive self -closing water shut-off nozzle or device, or for very short periods of time for the express purpose of adjusting or repairing an irrigation system.

7. No Excessive Water Flow or Runoff: The application of water is prohibited to outdoor landscapes in a manner that causes runoff such that water flows onto adjacent property, non- irrigated areas, private and public walkways, driveway, street, alley, gutter, ditch, parking lots, or structures.

8. No Washing Down Hard or Paved Surfaces: Washing down hard or paved surfaces is prohibited, including but not limited to buildings, structures, sidewalks, walkways, driveways, parking areas, tennis courts, patios, or alleys.

9. Obligation to Fix Leaks, Breaks or Malfunctions: All leaks, breaks, or other malfunctions in the water user's plumbing or distribution system must be repaired within seventy-two (72) hours of notification by the city unless other arrangements are made with the city.

10. Recirculating Water Required for Water Fountains and Decorative Water Features: Operating a water fountain or other decorative water feature that does not use recirculated water is prohibited.

11. Limits on Washing Vehicles: Using water to wash or clean a vehicle is prohibited, including but not limited to any automobile, truck, van, bus, motorcycle, boat, or trailer, whether motorized or not, except by use of a hand-held bucket or similar container or a hand-held hose equipped with a positive self -closing water shut-off nozzle or device. This subsection does not apply to any commercial car washing facility.

RIMMAMMUMMUARMARMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARM San Benito Urban Areas UWMP 2025

12. Drinking Water Served Upon Request Only: Eating or drinking establishments, including but not limited to a restaurant, hotel, cafe, cafeteria, bar, or other public place where food or drinks are sold, served, or offered for sale, are prohibited from providing drinking water to any person unless expressly requested.

13. Commercial Lodging Establishments Must Provide Guests Option to Decline Daily Linen Services:

Hotels, motels and other commercial lodging establishments must provide customers the option of not having towels and linen laundered daily. Commercial lodging establishments must prominently display notice of this option in each bathroom using clear and easily understood language.

14. No Installation of Single Pass Cooling Systems: Installation of single pass cooling systems is prohibited in buildings requesting new water service.

15. No Installation of Non -re -circulating in Commercial Car Wash and Laundry Systems: Installation of non -re -circulating water systems is prohibited in new commercial conveyor car wash and new commercial laundry systems.

16. Commercial Car Wash Systems: Within one year of passage of this Ordinance, all commercial conveyor car wash systems must have installed operational re -circulating water systems, or must have secured a waiver of this requirement from the city.

17. Pool Covers and Refilling of Existing Pools: All new pools shall be required to have a pool cover or solar blanket to reduce water loss through evaporation. Refilling of existing private pools is prohibited, except to maintain water levels, unless the pool is in imminent danger of failure.

Stage 3
The third stage seeks a 20 to 30 percent reduction of water demand. During this stage, the shortage response actions for Stages 1 and 2 will be in place. The shortage response actions for this stage are derived from the 25 percent reduction stage established in the 2016 WSCP. Stage 3 contains the same response actions as Stage 2. SBUA may choose to increase response action monitoring and enforcement in Stage 3, as well as encouraging water users to adopt additional voluntary conservation measures.

Stage 4
Stage 4 aims for a 30 to 40 percent reduction. It allows the agencies to restrict water uses to priority needs and the prohibited or limited uses of water become more restrictive. These restrictions are derived from the 35 percent reduction stage in the 2016 WSCP.

1. Limits on Watering Days: Watering or irrigating of lawn, landscape or other vegetated area with potable water is limited to two days per week from April through October. The watering days are designated depending upon house address (odd house and no house address - Monday and Thursday, even house address - Tuesday, and Friday). During the months of November through March, watering or irrigating of lawn, landscape or other vegetated area with potable water is limited to no more than one day per week (odd house and no house address - Monday, even house address - Tuesday). This provision does not apply to landscape irrigation zones that exclusively use very low flow drip type irrigation systems when no emitter produces more than

two (2) gallons of water per hour. This provision also does not apply to watering or irrigating by use of a hand-held bucket or similar container, a hand-held hose equipped with a positive self - closing water shut-off nozzle or device, or for very short periods of time for the express purpose of adjusting or repairing an irrigation system. Use of recycled water for irrigation is exempt from these restrictions.

2. Irrigating Within 48 Hours of Rainfall: The applications of potable water to outdoor landscapes during and within 48 hours following measurable rainfall is prohibited.

3. Irrigation outside Newly Constructed Homes: The irrigation with potable water outside of newly constructed homes and buildings in a manner inconsistent with regulations or other requirements established by the California Building Standards Commission is prohibited.

4. Installation of New Turf: Adding new turf landscaping is prohibited.

5. Prohibition against Watering Turf in Medians: The irrigation with potable water of ornamental turf on public street medians, including roundabouts is prohibited.

6. Obligation to Fix Leaks, Breaks or Malfunctions: All leaks, breaks, or other malfunctions in the water user's plumbing or distribution system must be repaired within forty- eight (48) hours of notification by the city unless other arrangements are made with the city.

7. Limits on Filling Ornamental Lakes or Ponds: Filling or re -filling ornamental lakes or ponds with potable water is prohibited, except to the extent needed to sustain aquatic life, provided that such animals are of significant value and have been actively managed within the water feature prior to declaration of a supply shortage level under this section.

8. New Pools: Installation and filling of new private pools are prohibited.

9. Dust Control: The use of potable water for construction and dust control is prohibited.

10. Drought Water Rates: Each agency may consider adopting rate structures and other mechanisms to maximize water conservation. These rates should be consistent with Prop 218's requirements.

11. Any of the SBUA agencies reserve the right to restrict water use for priority uses.

Stage 5
Stage 5 aims for a 40 to 50 percent reduction. The water shortage response actions in this phase are the same as those in Stage 4. Enforcement and monitoring may be increased during this stage to assist in decreasing water demand.

Stage 6
Stage 6 seeks at least a 50 percent reduction. This stage adds flow restrictions and a per capita allotment by customer type. The prohibited or limited uses of water in the previous stages are continued or made more restrictive. No watering or irrigating. Watering or irrigating of lawn, landscape or other vegetated area with potable water is prohibited. This restriction does not apply to recycled water. Exceptions are limited to the following:

1. Maintenance of vegetation, including trees and shrubs, that are watered using a hand-held bucket or similar container, hand-held hose equipped with a positive self -closing water shut-off nozzle or device;

RIMMAMMUMMUARMARMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARM San Benito Urban Areas UWMP 2025 Page 8-9

2. Maintenance of existing landscape necessary for fire protection;

3. Maintenance of existing landscape for soil erosion control;

4. Maintenance of plant materials identified to be rare or essential to the well-being of protected species;

5. Maintenance of landscape within active public parks and playing fields, day care centers, golf course greens, and school grounds, provided that such irrigation does not exceed two (2) days per week for no more than fifteen (15) minutes watering per designated water day per station and is prohibited between the hours of 9:00 a.m. and 5:00 p.m. Pacific Standard/Daylight Savings Time.

6. Actively irrigated environmental mitigation projects.

7. Obligation to Fix Leaks, Breaks or Malfunctions. All leaks, breaks, or other malfunctions in the water user's plumbing or distribution system must be repaired within twenty-four hours of notification by the city unless other arrangements are made with the water retailer.

8. Limits on New Potable Water Service: Upon declaration of a Level 4 Water Shortage Emergency condition, the agency may limit the issuance of new potable water services, temporary meters and/or statements of immediate ability to serve or provide potable water service (such as, can and will -serve letters, certificates, or letters of availability), except under the following circumstances:

9. A valid, unexpired building permit has been issued for the project; or

10. The project is necessary to protect the public health, safety, and welfare; or

11. The applicant provides substantial evidence of an enforceable commitment that water demands for the project will be offset prior to the provision of a new water meter(s) to the satisfaction of the agency providing service.

12. This provision does not preclude the resetting or turn -on of meters to provide continuation of water service or the restoration of service that has been interrupted for a period of one year or less.

13. Limits on Building Permits. Upon declaration of a Stage 4 Water Supply Shortage Emergency condition, the City Administrator is authorized to implement a program in his or her discretion to limit or withhold the issuance of building permits which require new or expanded water service, except to protect the public health, safety and welfare, or in cases which meet the city's adopted conservation offset requirements.

14. No New Annexations. Upon the declaration of Stage 4, the agencies may suspend consideration of annexations to their service area. This subsection does not apply to boundary corrections and annexations that will not result in any immediate increased use of water.

15. Each of the SBUA agencies reserves the right to restrict flow in water lines.

8.4.2 LOCALLY APPROPRIATE SUPPLY AUGMENTATION
During a water shortage emergency, the SBUA Agencies may choose to augment the water supply by increasing the proportion of groundwater in delivered water. Groundwater can make up for any decrease in CVP allocation during a drought. SBUA potable water is a mix of CVP water and groundwater to meet aesthetic standards. The average proportion of the supply that is CVP water was 50 percent over the past five years. The proportion of groundwater can be temporarily increased if the CVP supply is limited or

RIMMAMMUMMUMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARNMAMMUMWARMUM San Benito Urban Areas UWMP 2025

insufficient to meet demand. The preferred ratio of groundwater to imported water is 35:65, but this proportion may temporarily increase during periods of water shortage. Decreasing the proportion of potable water that is CVP is at the discretion of the SBUA agencies and may be enacted during stages 2 through 6. As shown in Table 8-3, augmenting the supply through increasing the proportion of groundwater in potable water is estimated to enhance the supply by up to 20 percent. Drought reserves in San Justo Reservoir can also augment supply during a water shortage emergency. However, these supplies are managed as exchanges or transfers (Section 6.2.7.2) and not as part of the WSCP.

8.4.3 CATASTROPHIC SUPPLY INTERRUPTION
Hollister, Sunnyslope, SJB, and the District also have water shortage emergency response plans in place.

The Drought Resilience Plan outlines a process for classifying water shortage stage (readiness, alert, and emergency) using indicators of water supply that activate defined actions to address the water shortage (Stantec Consulting Services Inc. 2026). A copy of this plan is included in Appendix E.

Hollister and Sunnyslope have a general Emergency Disaster Response Plan as well as a Power Failure Emergency Response Plans. The plans include steps to be taken during and after a disaster and the use of the Standard Emergency Management System (SEMS). Copies of these plans are included as Appendix F.

The District relies on their current Water User's Handbook and County emergency plans.

These plans develop the procedures for each agency before and during a disruption of water supply during a natural disaster. In 1999, the California Emergency Management Agency (Cal EMA) published Emergency Planning Guidance for Public and Private Water Utilities to improve coordination among water utilities and other emergency response agencies and to assist water utilities in developing or revising emergency plans and procedures. It is recommended that ongoing coordination between Hollister, Sunnyslope, SJB and the District take place to ensure these water supply emergency plans remain consistent and meet the goals provided in the guidance documents. With these plans in place, the retailers in the SBUA can adequately handle a water supply shortage due to a natural disaster or another interruption of the water supply (Cal EMA 1999).

The agencies' emergency shortage plans meet the requirements for the WSCP to include a seismic risk assessment and mitigation plan to assess the vulnerability of each water facility.

8.5 COMMUNICATION; PROTOCOLS
Effectively implementing any stage of the water shortage contingency plan requires clear and timely communication with the public, stakeholders, key decision makers, and local, regional, and state governments. The WSCP Communication protocols allow agencies to efficiently communicate any current or predicted water shortages and the response actions that are triggered. Communication protocols are outlined for each stage. In order to ensure consistency, each agency is encouraged to develop scripted responses to commonly asked questions when each stage goes into effect and, as information changes throughout a water shortage crisis.

• Will I get paid during times of reduced operation?

8.6 COMPLIANCE AND ENFORCEMENT

8.6.1 DEMAND REDUCTION THROUGH PUBLIC OUTREACH
During the most recent drought (2014-2016), public outreach was expanded by 200 percent, and a 25 percent reduction was achieved by both Hollister and Sunnyslope. These programs are discussed in more detail in Section 9. The specific public outreach measures listed below are intended to reduce demand during a drought or water supply interruption:
• Expand Public Information Campaign — Newsletter and other flyers in both English and Spanish were used to publicize programs and explain the importance of drought conservation.

20. Improve Customer Billing —Customers with higher -than -average bills were contacted and possible water savings were recommended.
• Offer Water Use Surveys— Both residential and landscape surveys help high water users to identify areas of potential conservation.

21. Provide Rebates or Giveaways of Plumbing Fixtures and Devices — Rebates and plumbing retrofits are available at all times, but are publicized more during drought conditions. Plumbing retrofits including hose nozzles, faucet aerators, and shower heads are available at no cost to customers.

Rebates are available for low flow toilets and high efficiency washing machines. • Provide Rebates for Landscape Irrigation Efficiency — There is currently a landscape efficiency rebate program that provides rebates for landscape conversion, low -volume sprinkler heads, rain sensors, hose timers, and includes customized sprinkler schedules. • Increase Water Waste Patrols — Examples include: Implement a Water Waste Patrol program; Increase staffing for Water Waste Patrol; Increase authority of Water Waste Patrol.

22. Moratorium or Net Zero Demand Increase on New Connections — The agencies have added a `no new connection' element to their WSCP that is triggered in Stage 4. • Implement or Modify Drought Rate Structure or Surcharge —a drought rate structure may be implemented in future droughts.

RIMMAMMEURREUMEMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEUMEM San Benito Urban Areas UWMP 2025

In addition to these measures, SBUA agencies offer ongoing educational programming, classes, and community outreach. Section 9 of the UWMP contains a more detailed descriptions of these programs.

8.6.2 WARNING AND CITATION PROTOCOLS
Enforcement is applicable at any water shortage stage. Any customer violating the regulations and restrictions on water use set forth in the "No Waste" Ordinances will receive a written warning for the first violation. A second violation within 12 months of the first violation results in a $100 penalty. On the third violation, the customer will be charged a $250 fine and the retailer may install a flow-restrictor. If a flow-restrictor is placed, the violator will pay the cost of installation and removal. After a fourth violation, a $500 penalty is issued. If water service is disconnected, it will be restored only upon payment of a reconnection charge. These penalties apply at any time but are likely to be more closely adhered to during drought periods.

Any willful violation occurring subsequent to the issuance of the second written warning will constitute a misdemeanor and may be referred to the City/County District Attorney's office for prosecution pursuant.

Misdemeanor convictions could include imprisonment and/or fines. The length of time for imprisonment and the magnitude of the fine vary between Hollister, Sunnyslope, and SJB. If water service is disconnected, it will be restored only upon payment of a reconnection charge. These penalties apply at any time but are likely to be more closely adhered to during drought periods. In addition to fines, Hollister, Sunnyslope, SJB, or the District, after written notice, may install a flow restrictor device or discontinue service to consumers who willfully violate provisions of this WSCP.

A person or property can apply for a waiver to the requirements in the WSCP. This hardship waiver is applicable at any stage of the WSCP. The written request must be submitted to one of the SBUA agencies with supporting documentation (photographs, maps, drawings, and any other information as appropriate). The waiver may be granted or conditionally granted only upon a written finding of the existence of facts demonstrating an undue hardship to a person using water or to property upon which water is used. The Agency that receives the waiver must act upon any completed application no later than ten days after submittal and may approve, conditionally approve, or deny the waiver. The applicant requesting the waiver must be promptly notified in writing of any action taken.

8.7 LEGAL AUTHORITIES
In the event of a water shortage, the SBUA Agencies shall declare a water shortage emergency in accordance with Water Code Chapter 3 Division 1.

Water Code Chapter 3 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.

RIMMAMMEUMEUMEMEWARMAMMEURREUMETAMARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEURREM San Benito Urban Areas UWMP 2025

The SBUA agencies shall coordinate with the cities of Hollister and San Juan Bautista and San Benito County for the possible proclamation of a local emergency, as defined in the California Government Code, California Emergency Services Act (Article 2, Section 8558).

8.8 FINANCIAL CONSEQUENCES OF WSCP;
During periods of water shortage, revenue of the SBUA agencies may be reduced as the WSCP is implemented. Decreased water demand will lead to decreased revenue at the normal billing rate. The WSCP calls for an increase in water demand reduction programs, such as expanded public information campaigns, water use surveys, rebates, and water waste patrols, which may result in increased spending and staff costs.

The SBUA agencies proactively prepare for periodic revenue shortages and periods of increased spending.

All surplus revenues that the District, Hollister, and Sunnyslope collect are currently reinvested into the water supply system in preparation for potential revenue reduction during water shortages.

Based on projected and observed declines in revenue during shortages, the entities determined that rate increases may be needed in Stage 2 through 6. In Stage 1, no additional water purchases and no rate increases are required. For Stages 2 & 3, 4 & 5, and 6, rate increases may be needed if the agencies decide to maintain the same revenue over this period.

8.9 `MONITORING, REPORTING, AND WSCP REFINEMENT PROCEDURES Under normal water supply conditions, potable water production values for Hollister, Sunnyslope, and SJB are recorded daily and reported monthly to the Water Supervisor. Water use will be monitored and analyzed through billing data. During a Stage 1, Stage 2, or Stage 3 water shortage, daily production figures will be reported to the Water Supervisor of each agency. The Supervisor will compare the weekly production to the target weekly production to verify that the reduction goal is being met. Weekly reports will be forwarded respectively to the General Manager of Sunnyslope, the Public Works Director at the City of Hollister, City Manager at SJB, and to the Program Manager of the WRA. During a Stage 4, 5, or 6 water shortage, the daily production report will be provided to the General or City Manager of each agency. In Stages 1 through 6, monthly reports will be sent to the Hollister City Council, the Sunnyslope Board of Directors, and the City of SJB Council. If reduction goals are not met, the respective managers will notify the governing board of each agency that additional action is required.

The WSCP implementation can be refined and updated at any point. During a water shortage, the agencies may make changes as needed to best fit the emergency and communicate these changes with the public and stakeholders. After a water shortage emergency has passed, the agencies are encouraged to evaluate the plan's effectiveness and may choose to adjust the WSCP to enhance its success, clarity, and feasibility.

8.10 SPECIAL WATER FEATURE DISTINCTION
Per Water Code Section 10632 (b) the SBUA Agencies shall define and analyze water features that are artificially supplied with water, such as ponds, places, waterfalls, and fountains, separately from

RIMMARMARMARMAMMETEMEWARMAMMEWARMAMMETEMEWARMAMMEWARMAMMETEMEUMEMEWARMARMAMMETEMEUMEMEWARMARMAMMETEMEUMEMEWARMARMAMMETEMEWARMAMMEURREUMEM San Benito Urban Areas UWMP 2025

swimming pools and spas. Water features that are not pools or spas may use recycled water, while potable water must be used in pools and spas for health and safety purposes.

8.11 ADOPTION SUBMITTAL, AND AVAILABILITY

NOTES:

9.1 WHOLESALE AGENCY PROGRAMS
The District is the wholesaler to Zone 6 (Northern San Benito County) for CVP imported water, while Hollister and Sunnyslope are retailers that purchase CVP water from the District. The District is currently working with SJB on the San Juan Bautista Pipeline, which will delivering high -quality surface water from the West Hills WTP to SJB. For this reason, SJB is now included in the SBUA. These four agencies have a strong partnership to plan the future water supply for the SBUA through this document and others, including the Master Plan and GSP. With regard to demand management, the District provides the conservation coordinator for the WRA, financial contribution and technical support to the WRA, and reporting on BMP implementation for Sunnyslope (not a signatory to the CUWCC MOU).

The District continues to:
• Join retail water agencies to plan, design, implement, manage, and evaluate regional conservation programs.
• Provide conservation -related technical support and information to retail agencies they serve. • Operate part of the conservation programs.
• Provide reports on BMP implementation within their service area by retail water agencies that are not signatories to the CUWCC MOU.
• Encourage all of their retail agencies to be part of the Water Resources Association (WRA).

9.2 DEMAND MANAGEMENT MEASURES FOR SBUA
Hollister, Sunnyslope, SJB and the District are committed to implementing water conservation and water recycling programs. The four agencies participate in the WRA of San Benito County. The WRA retains a Water Conservation Coordinator, who is a District employee, to serve the water conservation needs for the WRA members.

As required by USBR, the WRA coordinator also enters water conservation data to the CUWCC database for Sunnyslope and the District. Hollister's Utility Technician, a certified and functional Conservation Practitioner, enters this information into the CUWCC's database on behalf of the City. The CUWCC BMP number is included with each section for consistency with CUWCC reporting. The WRA coordinator also enters data for District activities into the Agricultural Water Management Council (AWMC) database each year as required by the Bureau. In addition, the WRA coordinator updates the Agricultural Water Management Plan for the District every five years.

UTILITY OPERATIONS RESOURCES — BMP 1
Water waste prevention ordinances. Hollister, Sunnyslope, and SJB have approved water conservation ordinances to reduce water waste at all times. San Benito County has also created a Water Conservation SitaRMIRMUNMEMMUNMEMMUNMEMMMUMMUMMUMMUMMUMMUNMMUMMUMMUMMUMMUMMUMMUMMUMMUMMUNMEMMEMMUNMMUMMUMMUNMEMMUMMUMMURVAMMUNMEMMUMENNMEM San Benito Urban Areas UWMP 2025 Page 9-1

Plan (also included in Appendix G). The plan prohibits certain water wasting uses, limits others, creates guidelines for plumbing fixtures in new developments, and encourages water conservation.

Metering. Hollister, Sunnyslope and SJB are fully metered and currently have meter replacement programs in place. Sunnyslope requires separate irrigation meters for commercial landscaping, parks, and other non-residential water services.

Tiered pricing. A tiered pricing structure is always in place and is not dependent upon a water shortage for implementation, although a future rate structure could include drought rate structures. Tiered pricing sends a signal to customers regarding their water use. Hollister, Sunnyslope, and SJB use a tiered rate structure for single family residences, where efficient water use is billed at a low price, and higher water use is billed at progressively higher prices. The rate structures are included in Appendix H.

Programs to assess and manage distribution system real loss. Hollister, Sunnyslope, and SJB generally have small water losses for the overall system. Each retailer regularly inspects the distribution system, to check for leaks. In addition, customers are contacted if water bill increases suggest leaks.

PUBLIC EDUCATION AND OUTREACH — BMP 2
WRA, through its Water Conservation Coordinator and other staff, supports a variety of public education and outreach efforts. This includes bill inserts, flyers, Water Awareness Month, school presentations, and more. Water Awareness Month (WAM) is in May at the start of the irrigation season. The timing is optimal to remind water customers about irrigation programs and water efficiency. In addition, Proclamations are read at the Member Agencies board and council meetings as well as the Board of Supervisors meeting in proclaiming May as Water Awareness Month. During WAM, a banner is strung across San Benito Street to urge people to contact their water provider for water saving ideas, the WRA sets up a booth at the local Farmer's Market and holds workshops or classes covering a variety of topics concerning water use reduction.

The WRA retains a Water Conservation Coordinator, who is a District employee, to serve the water conservation needs for the WRA members. This person's duties focus primarily on ongoing programs within the District to encourage wise water use among the urban community and within the SBUA. The duties of this position (and any support staff, as necessary) are described in section 9.3.

RESIDENTIAL PROGRAMS — BMP 3
Residential Surveys. This survey is a free home water conservation checkup including identification of the need for plumbing retrofits, a water softener check, household leak checks and identification of other possible water conservation improvements.

Plumbing Retrofits. As a complement to the residential surveys, WRA offers plumbing retrofits that replace older shower heads, add aerators in faucets and free hose nozzles. While this program has been successful in the past and is estimated to have reached over 75 percent of customers, it may not provide significant water demand reduction in the future because of its past success.

High Efficiency Clothes Washers (HECW) Rebates. These HECW use half as much water as traditional top loading clothes washers. These machines also use less detergent and help protect the quality of groundwater supplies. This rebate has been discontinued and is no longer available.

Toilet Rebates. Rebates and giveaways are available for residential customers who replace existing toilets with high efficiency models. This program was discontinued in 2018 as only high efficiency toilets are now available for purchase.

Water Softener Rebate Program. Since 2007, a program has been in place to issue rebates to those water customers who remove self -regenerating water softeners (SRWS) without replacement ($300) or with transition to an off -site exchange service ($250). In July 2014, the City of Hollister enacted an ordinance that prohibits the installation of SRWS that use sodium and/or potassium salts. In February 2015, Sunnyslope adopted a new District Code prohibiting the installation of SRWS that use sodium and/or potassium salts.

Residential Bill Comparison. In addition to public outreach information. The agencies revised their bills to reflect a comparison of 2013 water consumption and current consumption for customers to gauge their reduction efforts.

High -Bill Contact Programs. These programs alert residential users if the monthly bill is higher than a pre- determined threshold and is implemented by the retailers directly. This will help the residential user identify leaks or changes in water use.

Notification of Leaks. If a leak is detected on a customer's property, they are alerted so they can repair the leak and avoid further water waste.

CI' PROGRAMS — BMP 4
Commercial High - Efficiency Single Load Clothes Washers. Rebates are available for commercial customers who replace existing washers with high efficiency single load machines.

Commercial High - Efficiency Toilets. Rebates are available for commercial customers who replace existing toilets with high efficiency model.

Green Business Certification. The WRA is working together with the San Benito County Chamber of Commerce to recognize and promote businesses and government agencies that volunteer to operate in a more environmentally responsible way. WRA staff sits on the board of the Chamber of Commerce's Green Business Committee and actively participates in the Green Business Certification Program. The WRA's partners include Integrated Waste, Recology and PG&E.

Hotel Program. The WRA provides table cards to hotels and motels that allow guests to have linens washed only upon request.

LANDSCAPE PROGRAMS — BMP 5
Landscape Water Surveys. This survey is a free water conservation checkup for large urban irrigators including the identification of needs for plumbing retrofits and/or updated irrigation hardware, leak checks and identification of other possible water conservation improvements.

Landscape Irrigation Hardware Rebate Program. The WRA has rebates on hose timers, rain sensors and MP Rotator irrigation nozzles and sprinkler bodies with pressure regulators. A rebate is offered of 50 percent of the cost of qualifying products, up to $100.

Turf Removal Program. During the last drought (2014-2015) over 88,000 square feet of turf were removed in the Hollister Urban Area. This turf removal program included extensive public outreach in Spanish and English. The program is not currently active but may be used in the future as needed.

Irrigation Education. Since 2009 the District, in collaboration with the WRA, has offered a series of classes on irrigation efficiency and other agriculture practices.These workshops provide concepts, tools, and examples for optimizing irrigation and nitrogen management efficiency in row, tree, and greenhouse crop production. The classes also focus on keeping records and acquiring data needed for water quality regulation and reporting. The WRA also offers classes to residential customers. These classes instruct customers on topics such as efficient irrigation practices, converting landscapes to be water wise, and composting.

Custom Sprinkler Schedule. A Water Conservation Specialist will design a watering schedule tailored to customer habits, sprinkler's output, and the seasonal water needs of the individual lawn and garden. The plan is free and includes a schedule for each season, and even programming of the automatic sprinkler timer upon request.

Landscape Plans. The WRA offers three professional landscape plans, meadow, dry creek, and strolling garden themes, to replace high -water -use gardens. These plans, each valued at $500, emphasize native plants to support biodiversity and utilize permeable features like pavers to improve groundwater recharge. Between 2020 to 2025, there were 4,780 downloads of these plans.

9.3 IMPLEMENTATION OVER THE PAST FIVE YEARS
Each DMM listed above is discussed below including the following details:
• Nature — Description of the DMM program (e.g., the dollar value for individual toilet replacements, the process used to inform customers of a landscape water budget program, or the content of a school education program.)
• Extent — Quantification of the implementation of the DMM (e.g., the number of customers who have used the toilet rebate program, the number of large landscape accounts that have been assigned a water budget, or the number of school presentations given by the WRA). In addition, extent includes a description of the methods used to estimate the expected water savings from DMMs, or the agency's implementation plan for a particular DMM.

RIMMAMMUMMUARMARMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARM San Benito Urban Areas UWMP 2025

The SBUA continues to show its dedication to water demand management by steady funding for the WRA.

The annual budget has increased from $324K in fiscal year 2015-2016 to $372K in fiscal year 2020-2021 (not including additional funds for development of this UWMP). A more detailed budget by DMM was not available. A summary table on the following page shows the implementation from 2011 to 2015 and 2016 to 2020.

WATER WASTE PREVENTION ORDINANCES
The ordinances were originally created as a response to the multiple dry years of the early 1990's but have continued to support sustainable water supply by prohibiting water wasting activities, which include:
• Indiscriminate or excessive water use, which results in water waste. • Washing of cars, buildings, or exterior surfaces without the use of a quick -acting, positive shut-off nozzle.
• Use of potable water to irrigate turf, lawns, gardens, or ornamental landscaping between 9:00 a.m. and 5:00 p.m. by means other than drip irrigation or hand watering with a quick -acting, positive shut-off nozzle.
• Use of potable water to wash sidewalks or roadways when the use of airblowers or sweeping would provide a reasonable alternative.
• Allowing water waste caused by easily correctable leaks, breaks, or malfunctions, after a reasonable time within which to correct the problem.
• Operation of decorative fountains, even if they use recirculating systems. • Use of water for construction purposes, such as consolidation of backfill, except when no other method can be used.
• Restaurant water service unless upon customer request. • Hydrant flushing, except where required for public health and safety. • Refilling existing private pools, except to maintain water levels.

Hollister, Sunnyslope, SJB, the District, and San Benito County have all established "No -Waste" ordinances, policies, and resolutions for their respective jurisdictions. The District has a Water Users Handbook that explains how each water user must take steps to control tailwater. If these policies are not followed, the District has the authority to discontinue service.

In addition to these existing ordinances, Emergency Water Conservation Regulations were passed in 2015 that added outdoor water restrictions. The Emergency regulations also added penalties for violating these restrictions including fines for repeated violations. The Regulations are included in Appendix F.

The water waste ordinances are enforceable for retailer customers in the City of Hollister, Sunnyslope, and the City of San Juan Bautista. Enforcement costs are a part of each agency's overhead.

RIMMAMMEUMEUMEMEWARMAMMEURREUMETAMARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEURREM San Benito Urban Areas UWMP 2025 Page 9-7

The WRA handles complaints of water waste or pursues water waste violations if observed by staff. The WRA issues 'Water Waste' violation cards and follows up with letters to the violators and offers assistance to correct the problem.

METERING
Hollister, Sunnyslope, and SJB meter all customers within their service areas, and each retailer has a meter replacement program.

Hollister has been replacing approximately 700 to 800 meters annually, about 10 percent of total connections. As of early 2008, nearly half of the City's old meters have been replaced with new meters that allow reading through a radio. Hollister is making continuous efforts to identify the number of accounts by specific customer type, including installation of dedicated landscape meters for customers who had mixed -use meters. Meter installation costs are part of new service connection fees.

Sunnyslope began the meter replacement program about 10 years ago, replacing up to 600 meters annually, 11 percent of total connections. Sunnyslope's goal is to replace any meter older than 15 years to ensure meter accuracy. In Fiscal year 14/15, approximately 350 water meters were replaced; Sunnyslope added staff to assist with this maintenance task in January 2015.

In 2016 San Juan Bautista began an infrastructure replacement program to modernize its aging water system, which consists of approximately 735 meters, including 38 commercial accounts. City employees replaced the entire assorted mix of unreliable, century -old meters within a five -month period, including the installation of 275 new meter boxes. The city transitioned to a Master Meter 3G AMR (Automated Meter Reading) drive -by system, utilizing Multijet meters for residential connections and Octave° ultrasonic meters for commercial districts to ensure high -flow accuracy. This modernization reduced meter reading time for the city's small staff from over a full day of manual entry to less than one hour.

The new system provides detailed data logging to assist with leak detection and conservation efforts, while the increased accuracy ensures more reliable revenue for the city's enterprise fund. San Juan Bautista intends to eventually upgrade this flexible system to a full AMI (Advanced Metering Infrastructure) as future revenues allow. Currently, SJB does not have a formal water meter replacement program, and meters are replaced on an as -needed basis. Between 2020 to 2025, fewer than 20 water meters were replaced.

CONSERVATION PRICING
Hollister, Sunnyslope, and SJB use a tiered rate structure for single family residences, where efficient water use is billed at a low price and higher water use billed at progressively higher prices. The entities assess a monthly service charge based on water meter size, plus a monthly consumption rate based on the amount of water consumed.

The monthly consumption rates for single-family residential customers are an inclining block with three tiers, while non -single-family customers are charged one rate for all water consumption. Hollister, Sunnyslope, and SJB tiers and rates are included in Appendix H.

Hollister recently increased water rates in April 2026 after approval by the City Council in February 2026.

The current Sunnyslope multi -year water rates as proposed in Ordinance 82 were approved by the Board of Directors on May 28, 2024 and took effect on August 1, 2024 with annual updates through July 1, 2029.

After conducting a water rate study, SJB set its current rates in May 2022 under Resolution No. 2022-38.

Comparison with previous average usage rates might provide some information regarding the effectiveness of changing from non -conserving to conservation pricing. It is assumed that the economic incentive to customers to conserve water under conservation pricing structures is sufficient to make this program efficient.

It is expected that most of the conservation savings will occur with the largest water users, who will see larger benefits for conserving water. The expected annual water savings is 100 AFY, compared to the scenario where non -conserving pricing is used.

PUBLIC EDUCATION AND OUTREACH
Public outreach is central to the SBUA water conservation efforts. These ongoing activities were ramped up in response to the State mandated water conservation. Specific activities include:

23. Newsletter articles on conservation - These articles are included as Appendix I.

24. Flyers and/or brochures, bill stuffers, messages printed on bill, information packets. The flyers are included as Appendix I.
• Development and update of a website with resources for water conservation:
www.wrasbc.org.The website provides details about ongoing water conservation programs and has three different water wise landscape plans available for download. Last updated in December 2020.
• Booths at Children's Festivals and Farmer's Market.
• Engagement with the community through responsiveness to emailed questions and concerns. • Water Awareness Festival in May.

The full-time water conservation coordinator records the number and type of outreach activities.

Newsletters are sent with water bills and are estimated to reach 40,000 people per year. Booths at festivals reached over 6,500 people in the last five years. Other outreach includes the website and email communication which reached about 1800 people since 2016.

While there is no direct way to quantify public outreach, it is the foundation for all other programs. With methods to advertise and connect customers to other programs and information, all other demand management measures would be less effective. In addition, the expanded public outreach in response to the drought shows a direct connection between increased public outreach and decreased water use.

SCHOOL EDUCATION AND OUTREACH
The WRA also provides specific school focus outreach including:
• Presentations to school groups (both classroom and large assemblies o Water Cycle presentation to 4 and 5th graders
o Water and Your World presentation to elementary students • Field trips to the Water Treatment Plant and Wastewater Treatment Plant • Water Careers Education
The number of students who have participated in these school programs totaled 3,550 in the last five years. WRA will continue to reach out to students at all grade levels. Before the start of each school year, the Water Conservation Coordinator visits every school in the SBUA to alert them of the School Education Program offered through the WRA. The direct effect on water demand is not quantifiable, but there is long-term benefit to educating students on the science and impacts of water supply and conservation.

PROGRAMS TO ASSESS AND MANAGE DISTRIBUTION SYSTEM REAL LOSS As all connections in Hollister, Sunnyslope, and SJB are metered, water loss in the SBUA is due to leaks, flushing fire hydrants, maintenance of water tanks, metering accuracy, and other small unmetered releases due to maintenance procedures. No additional programs are planned to further manage water distribution system losses.

WATER CONSERVATION PROGRAM COORDINATION AND STAFFING SUPPORT The WRA conservation coordinator's duties focus primarily on ongoing programs within the District to encourage wise water use among the agricultural community and within the SBUA. The duties of this position (and any support staff, as necessary) include the following:
• Coordination and oversight of conservation programs and BMP implementation • Preparation and submittal of the CUWCC BMP Implementation reports • Communication and promotion of water conservation issues to agency senior management • Coordination of agencies' conservation programs with operations and planning staff • Preparation of annual conservation budget
• Attendance at Bay Area Water Conservation Coordinator Meetings with representatives from the CUWCC
• Reporting to the governing bodies of the participatory agencies on the progress of the Water Conservation Program.

As required by USBR, the WRA coordinator also enters water conservation data to the CUWCC database for Sunnyslope, the District, and San Juan Bautista. Hollister's Utility Technician, a certified and functional Conservation Practitioner, enters this information into the CUWCC's database on behalf of the City of Hollister.

RIMMAMMEURREUMEMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEUMEM San Benito Urban Areas UWMP 2025 Page 9-10

The water conservation coordinator works on behalf of the WRA which includes Hollister, Sunnyslope, SJB, and the District. Like public outreach, this demand management measure provides a foundation for all other programs. Having key personnel to coordinate ongoing programs and begin new initiatives is critical for continued water use efficiency. The Conservation Coordinator will continue to oversee water conservation activities for the SBUA. To gauge the effectiveness of this DMM, the conservation coordinator and Hollister staff will continue to document the number of programs, materials and attendance at water conservation activities. The benefits of a coordinator are indirect and the water savings due to this DMM cannot be quantified.

Residential Surveys
This DMM involves assisting customers with leak detection and minimization. This may include but is not limited to: a water conservation survey, water efficiency suggestions and/or inspection, and provision of showerheads and faucet aerators that meet current Water Sense specifications. The primary focus is on older neighborhoods with pre -1980 plumbing and the second priority is other pre -1992 housing. Houses constructed after 1992 were required by state building codes to utilize water conserving plumbing fixtures. The program is marketed through advertising in bill inserts, bill messages, and newsletters.

During the water survey, water conservation staff perform the following:
• Check for leaks, including toilets, faucets, and meter check • Check showerhead flow rates, aerator flow rates, and offer to replace or recommend replacement, as necessary
• Check toilet flow rates and direct customer to ultra -low flush toilet (ULFT) replacement programs, as necessary, and replace leaking toilet flappers and floats if applicable • Check irrigation system and timers
• Review or develop customer irrigation schedule
• Evaluate water softener operations and test water hardness to ensure proper settings • Promote the retrofit program and provide other information on local water resource topics Surveys require between 30 and 90 minutes. For each dwelling unit, a Water Conservation Assistant completes a customer data form (including number of people per household, number of bathrooms, age of clothes washer and water softener, and approximate landscaped area square footage). These data are used to analyze the customer's water use for both pre- and post -audit conditions, and to refine the program. The results of the residential water survey are provided to the customer with water saving recommendations and specific local information packets prepared as part of the public information program described for DMM 7. The individual contacts made during the survey are used to actively promote the other programs and services offered by the Water Conservation Program, including retrofit and rebate programs offered under other BMPs. Both English and Spanish speaking persons conduct the surveys, and both English and Spanish language materials are available. The form used in the survey is shown in Appendix I.

In the last five years, over 1,234 single family homes and 32 multiple family units have participated.

RIMMAMMEURREUMEMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEUMEM San Benito Urban Areas UWMP 2025 Page 9-11

Based on available information, the potential water savings from this BMP are estimated to be 20 to 30 gpd and 18 to 28 gpd for single family and multi -family residences, respectively. This savings would be approximately 187 AF over the last five years. It is expected that the number of surveys per year will decline with the decrease in older residences that have not completed these surveys.

REBATES AND RETROFITS
The WRA provides several rebates and plumbing retrofits for residential customers, including:
• Plumbing retrofits (shower heads, aerators in faucets and free hose nozzles) • Water Sense Specification (WSS) toilets
• Water Softeners (demolishing)
• Turf Removal Rebate
• Water Softener Rebate
• Low -flow Toilet Rebate
• Landscape Hardware Rebate
The rebate programs have been very active and successful. The three major programs (High Efficiency Clothes Washers (HECW), low flow toilets, and water softeners) have all seen great success in the past but the number of rebates issued has decreased as water efficient fixtures dominate the market. In the past, water savings from these programs has totaled up to 130 AFY.

The HECW rebate was $100 per washer. From 2016 until the program was discontinued, 18 rebates for HECW had been issued. The CUWCC reports a water savings estimate of 5,250 gallons per year (0.2 AFY) per high efficiency washing machine, for a total savings of 3.6 AFY.

For WSS toilets, a free toilet is offered or a $75 rebate towards a new toilet. In addition, the WRA provides a free toilet by appointment, limited to two free toilets per residence, unless a WRA representative inspects the property to confirm more than two toilets are required. In the past, this program has been extremely successful, with over 7,000 ULFTs installed from 2001 to 2015. In the last five years, only 425 toilets rebates were issued. Projected total annual water savings from toilet retrofits at full implementation are 20 gpcd each or 30 AFY for rebates issued (2016-2020), both in water demand and wastewater generation. The decrease in rebates and budget are another indication that the area already has many water saving devices with limited additional water savings potential.

Since 2007, WRA has conducted a water softener rebate program that encourages people to upgrade from their timer -based models (pre -1999) to demand -initiated regenerating (DIR) models or to demolish these older softeners with no replacement. A shared goal of the District, Hollister, Sunnyslope, and SJB is to reduce salt loading to wastewater and thereby help maintain groundwater quality and support water recycling. The program includes water softener checks as part of the home water audit programs. It also provides the public with information about DIR and exchange -type water softeners, encouraging replacement of less efficient timer models Currently, there are two rebates; $300 for water softener removal or $250 for upgrading to a salt/potassium-free system. The water softener rebates are funded by

RIMMAMMEUMEUMEMEWARMAMMEURREUMETAMARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEWARMAMMEURREM San Benito Urban Areas UWMP 2025 Page 9-12

a grant. It is estimated these rebates save 600 gallons per month per household. In the last five years, 159 rebates were issued, for an estimated total savings of three AFY.

While water softener rebates do help reduce water demand, a major benefit is the decrease in salt discharge in the wastewater. The salt reduction is critical to improving water quality of the wastewater discharge, recycled water, and indirectly the groundwater basin.

COMMERCIAL, INDUSTRIAL, AND INSTITUTIONAL PROGRAMS
The WRA works with businesses to encourage water conservation. The two main programs include the Green Business Certification which recognizes and promotes businesses and government agencies that volunteer to operate in a more environmentally responsible way. The other program serves hotels and provides table cards to hotels and motels that allow guests to have linens washed only upon request.

These programs are conducted jointly with SBC Chamber of Commerce. The WRA works closely with their partners to establish policies that are both business friendly and promote environmental stewardship. As part of this partnership, they produce the TV show "Going Green" which is aired on the Community Media Access Partnership through the local cable provider (Charter). This show discusses "green" topics including water conservation both locally and worldwide.

There is no single budget amount for these programs administered by the water conservation coordinator.

LANDSCAPE WATER SURVEYS
A landscape water survey includes a check of an irrigation system and timers for maintenance and repairs needs, development of a customer irrigation schedule, reviewing scheduling with the customer, and providing the customer with an evaluation.

During a survey, the WRA checks irrigation schedules to see if they are adjusted for the season, checks/adjust sprinkler heads to make sure landscape is being irrigated and not fences or walkways, etc., develops an irrigation schedule to follow for the year, and makes recommendations to upgrade or repair equipment.

Hollister has a landscape ordinance that pertains to new and existing single-family homes and has adopted the model water efficiency landscape ordinance (MWELO) to promote landscape irrigation efficiency. The City is also considering a financial incentive program to help homeowners to convert landscaping toward more water efficiency (e.g., landscape materials, irrigation conversions, automatic controllers, etc.) The WRA water conservation coordinator offers water use surveys and audits to single family residences, which are modified versions of audits offered to large landscape customers. The WRA also publishes a newsletter biannually entitled, "Water Conservation Update", included in Appendix I. The newsletter provides landscape water conservation information and suggests seasonal water conservation measures such as turning off irrigation systems in the fall. WRA also offers free irrigation inspections in the spring and irrigation controller assistance in the fall. The WRA website provides useful tips for outside water

RIMMAMMUMMUARMARMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARMARNSMARM San Benito Urban Areas UWMP 2025 Page 9-13

conservation, a Watering Index to guide irrigation, and a Residential Lawn Watering Guide. The website also promotes a free custom sprinkler schedule.

In the last five years, over 950 surveys were performed or survey information downloaded. The water savings of this measure would depend on the existing volume of irrigation and the implemented reduction of irrigation. The 2010 UWMP estimated 25-50 AFY savings for this program.

The City of Hollister and the County have adopted Large Landscape Conservation Requirements, including the MWELO. The SBUA entities will continue to implement this DMM through annual review of customers' water use, and by offering on -site follow-up evaluations to customers whose total water use exceeds their total annual water budget. The overall target of providing large landscape audits is 3 percent of existing accounts each year.

Landscape Irrigation Hardware Rebate Program
The WRA has rebates on hose timers, rain sensors and MP Rotator irrigation nozzles. Information on how residents apply for this rebate and what models are available are included in Appendix I. Five rebates were issued for this program.

Turf Removal Program
During the last drought (2014-2015) over 88,000 square feet of turf were removed in the Hollister Urban Area. This turf removal program included extensive public outreach in Spanish and English. The turf was removed and either replaced with hardscape, drought tolerant plants or a combination of both. While the program is not currently active, the water savings effects of the removed drought will continue unless new turf is planted. This program may be brought back for future droughts as needed.

IRRIGATION EDUCATION
Since 2009, the District, in collaboration with the WRA, has been offering a series of classes on irrigation efficiency and other agriculture practices. These workshops provide concepts, tools, and examples for optimizing irrigation and nitrogen management efficiency in row, tree, and greenhouse crop production.

The classes also focus on keeping records and acquiring data needed for water quality regulation and reporting. The WRA also offers classes to residential customers. These classes instruct customers on topics such as composting, implementing efficient irrigation practices, and converting landscapes to be water wise. From 2016 to 2019, these classes reached 300 participants. There were no classes in 2020 due to the COVID-19 pandemic, but these classes resumed in 2021.

Custom Sprinkler Schedule
A Water Conservation Specialist will design a watering schedule tailored to customer habits, sprinkler's output, and the seasonal water needs of the individual lawn and garden. The plan is free and includes a schedule for each season plus programming of the automatic sprinkler timer.

RIMMARMARMARMAMMUNSMARMAMMUNSMARMAMMUNSMARMAMMUNSMARMAMMUNSMARMAMMUNSMARMAMMUNSMARMAMMUNSMARMAMMUNSMARMAMMUNSMARMAMMUNSMARMAMMUNSMARMARM San Benito Urban Areas UWMP 2025 Page 9-14

In the last five years, it is unknown how many schedules have been developed for large landscapes customers; between 2016 to 2020 150 were developed. It is estimated that a custom sprinkler schedule could reduce irrigation by 20 to 30 gallons per day, for a total of 5 AFY for the schedules recently implemented. This program can be expanded by reaching out directly to large landscape as well as residential customers. Schedules are created for residential customers through the water survey program.

9.4 PLANNED IMPLEMENTATION TO ACHIEVE WATER USE TARGETS (RETAIL AGENCIES ONLY) Water conservation efforts over the past five years have resulted in numerous plumbing and hardware retrofits in older buildings. These existing efforts (combined with new plumbing codes that require new developments to have water saving fixtures) have resulted in a large percent of buildings (both residential and commercial) with water saving technology. While these improvements have resulted in decreased water demand, the future potential gains from the rebate and retrofit programs may be limited.

In response to the State mandated water reduction due to the 2016 drought, the WRA and agencies stepped up their public outreach. They increased bill inserts, contacted high water users, and increased the advertisement of existing programs in multiple languages. In addition, the WRA also used public outreach to alert users to the new Emergency Water Conservation Regulations. These regulations focused on implementing efficient irrigation and outdoor water use. The increased public outreach and the focus on reducing water waste outdoors had measurable results. The agencies were able to reduce water demand in 2015 by more than 25 percent.

The water demand has continued to remain low and has not rebounded to pre -drought water use. This is due in large part to the public outreach and permanent changes enacted during the drought. Turf that was removed has not been replaced, high efficiency appliances remain in homes, and landscape plans continue to keep irrigation efficient.

The WRA plans to continue its focus on public outreach and education about irrigation efficiency. While these programs are difficult to account per unit water savings, the overall effect of reducing demand during the drought demonstrates the overall water savings.

Contingency Plan
ii TODD GROUNDWATER

TE S I. EC TI E
CY PL 225
Each urban water supplier must develop and adopt a Water Shortage. Contingency Plan (WSCP) as part of its Urban Water Management Plan (UWMP) every five years. The District, the City of Hollister, Sunnyslope, and the City of San Juan Bautista have developed a joint UWMP for the San Benito Urban Area (SBUA) for 2025. In addition, the SBUA agencies have updated the Water Shortage Contingency Plan (WSCP). This Plan serves as a guide for adjusting supply and demand in response to a water shortage.

The original WSCP was developed in 2016 as part of the 2015 Urban Water Management Plan and provides details on how to reduce demand in the event of a water supply shortage.

In response to the 2012-2016 drought, a new WSCP mandate required WSCPs to provide a more detailed analysis of supply and demand contingency actions and plan implementation for the 2020 WSCP. The retailers responded by updating the documentation of plan procedures and implementation, standardization of water supply stages of action for the water supply plan, and quantification of contingency action effects on supply and demand.

Updates to the WSCP for the 2025 UWMP planning cycle focus on the inclusion of the City of San Juan Bautista and the WSCP is now a stand alone document. Per DWR's guidelines, the WSCP will be adopted in a Public Hearing along with the 2025 UWMP for all the agencies.

Pursuant to Water Code Section 10632(a)(3), all WSCPs must include a six -stage plan corresponding to shortage stages of up to 10 percent, 20 percent, 30 percent, 40 percent, 50 percent, and greater than 50 percent of water supply. During the 2012-2016 drought years, differences in state and local definitions led to uncertainty in public communication and state policy. The standardization is meant to aid communication and response action implementations across the state.

Water Code Section 10632(a)(3)(B) allows suppliers to retain existing water shortage response plan stages if the existing stages are directly related to the specified six stages. The four stages identified by the previous WSCP translate to the six new stages, as shown in Table 1-1. For the new Stage 1, up to 10 percent reduction, the voluntary measures for the previous stage 1 (up to 15 percent) are applicable. For both 10 to 20 percent and 20 to 30 percent reductions, Stage 2 restrictions are applicable, aiming for 25 percent reduction. For 30 to 40 percent and 40-50 percent reductions, Stage 3 is applicable, which aims for 35 percent reductions. Finally, for greater than 50 percent reductions, the Stage 4, is applicable for over 50 percent reduction.

1.2. SHORTAGE RESPONSE ACTIONS
Water shortages can be met by augmenting the supply and/or decreasing the water demand. Each response action must be implementable. In this section and in section 8 of the UWMP, the response actions for each stage are outlined, along with the methodology for calculating action effectiveness. Table 1-2 summarizes each demand reduction action, the stages in which they are implemented, and the estimated percent by which they can decrease demand.

In response to the WSCP guidelines, the effectiveness of each action has been quantified for SBUA using the best available data. It should be noted that the effectiveness of many shortage response actions have not been studied and effectiveness can vary by region.

These estimates are best used as guidelines to inform decision makers which actions may contribute most to demand reductions. The methods for calculating the effectiveness of each action are outlined in the UWMP, Appendix G. In addition to the methods outlined as part of the WSCP, further demand reductions (particularly with indoor residential water use) are expected due to outreach, education, and social pressures.

The effectiveness of each action was estimated based on the observed water demand reduction during the 2014-2016 drought, studies and literature reviews examining the effectiveness of individual and combined response actions, and calculations of demand decreases scaled to the regional population. These estimates reflect best available data; however, it should be noted that the estimates are also uncertain. Historical data on demand reductions during drought, both within SAN BENITO URBAN AREA and in case studies, are a result of combined demand restrictions, public education, and social pressures. There are very few studies of the effect of individual actions. In addition, a variety of assumptions are used in calculations of water demand as reduced by a given action. For example, estimating the money saved by restricting at-home carwashes involved assumptions about how many Hollister Urban Area residents would wash their car at home in a non -drought month, how many of those carwashes would use a hose with a nozzle, and how much water each wash would use. Furthermore, several restrictions rely on postponing San Benito 2025 UWMP

actions or implementing large water -use projects, such as filling up a new pool, removing a single -pass cooling systems, or receiving a large new water permit.

1.2.2. Locally Appropriate demand reduction by stage
Implementation of restrictions and prohibitions on end users is based on a fundamental prioritization of domestic supply for human health and safety over non -essential uses, including landscape irrigation. In the event of a water shortage, water service may be restricted or prohibited for non -essential uses, recognizing that certain end users may be required to save more water than others because of their specific use. Prohibitions on end uses will affect user types differently:
• For urban residential users (who typically rely on SAN BENITO URBAN AREA agencies for domestic supply), water service will continue during a shortage with restrictions on outdoor water use in Stages 1 through 5 and prohibitions in Stage 6. • Rural residential users of CVP M&I water would also be subject to restrictions and prohibitions on outside water features and landscape irrigation. • Landscape irrigators (e.g., golf courses, dedicated irrigation meters) are subject to the restrictions listed below for Stages 1 through 5 and the prohibition in Stage 6. • Commercial businesses are subject to all restrictions in Stages 1 through 5 and prohibitions in Stage 6.

Stage 1
The first stage applies voluntary actions to reach the demand reduction goal of 10 percent, with a focus on outdoor irrigation demand reduction.

1. Recommended Watering Hours: Watering or irrigating of lawn, landscape or other vegetated area with potable water is discouraged between the hours of 9:00 a.m. and 5:00 p.m. Pacific Standard/Daylight Savings Time.

2. Recommended Limit on Watering Duration: Watering or irrigating of lawn, landscape or other vegetated area with potable water using a landscape irrigation system or a watering device that is not continuously attended is recommended to be limited to no more than three days a week with a duration of fifteen (15) minutes watering per water day per station. This subsection does not apply to landscape irrigation systems that exclusively use very low -flow drip type irrigation systems when no emitter produces more than two (2) gallons of water per hour and weather -based controllers or stream rotor sprinklers that meet a 70 percent efficiency standard. The use of recycled water is exempt from this prohibition.

3. Eliminate Excessive Water Flow or Runoff: Watering or irrigating of any lawn, landscape or other vegetated area in a manner that causes or allows excessive water San Benito 2025 UWMP

14. Pool Covers and Refilling of Existing Pools: All new pools shall be required to have a pool cover or solar blanket to reduce water loss through evaporation. Refilling of existing private pools is prohibited, except to maintain water levels, unless the pool is in imminent danger of failure.

Stage 3
The third stage seeks a 20 to 30 percent reduction of water demand. During this stage, the shortage response actions for Stages 1 and 2 will be in place. The shortage response actions for this stage are derived from the 25 percent reduction stage established in the 2016 WSCP. Stage 3 contains the same response actions as Stage 2. SAN BENITO URBAN AREA may choose to increase response action monitoring and enforcement in Stage 3, as well as encouraging water users to adopt additional voluntary conservation measures.

Stage 4
Stage 4 aims for a 30 to 40 percent reduction. It allows the agencies to restrict water uses to priority needs and the prohibited or limited uses of water become more restrictive. These restrictions are derived from the 35 percent reduction stage in the 2016 WSCP.

1. Limits on Watering Days: Watering or irrigating of lawn, landscape or other vegetated area with potable water is limited to two days per week from April through October.

The watering days are designated depending upon house address (odd house and no house address - Monday and Thursday, even house address - Tuesday, and Friday).

1.2.3. Locally Appropriate Supply Augmentation
During a water shortage emergency, the SBUA Agencies may choose to augment the water supply by increasing the proportion of groundwater in delivered water. Groundwater can make up for any decrease in CVP allocation during a drought. SBUA potable water is a mix of CVP water and groundwater to meet aesthetic standards. The average proportion of the supply that is CVP water was 61 percent over the past five years. The proportion of groundwater can be temporarily increased if the CVP supply is limited or insufficient to meet demand. The preferred ration of groundwater to imported water is 20:80, but this proportion may temporarily increase during periods of water shortage. Decreasing the proportion of potable water that is CVP is at the discretion of the SAN BENITO URBAN AREA agencies and may be enacted during stages 2 through 6. In Table 1-3, augmenting the supply through increasing the proportion of groundwater in potable water is estimated to enhance the supply by up to 20 percent. Drought reserves in San Justo Reservoir can also augment supply during a water shortage emergency. However, these supplies are managed as exchanges or transfers (UWMP Section 6.7) and not as part of the WSCP.

1.2.4. Catastrophic Supply Interruption
Hollister, Sunnyslope, and the District also have water shortage emergency response plans in place. Sunnyslope and the City have a general Emergency Disaster Response Plan as well as a Power Failure Emergency Response Plans. The plans include steps to be taken during and after a disaster and the use of the Standard Emergency Management System (SEMS).

Copies of these plans are included in the UWMP, Appendix H. The District relies on their current Water User's Handbook and County emergency plans.

These plans develop the procedures for each agency before and during a disruption of water supply during a natural disaster. In 1999, the California Emergency Management Agency (Cal EMA) published Emergency Planning Guidance for Public and Private Water Utilities to improve coordination among water utilities and other emergency response agencies and to assist water utilities in developing or revising emergency plans and procedures. It is recommended that ongoing coordination between the City, Sunnyslope, and the District take place to ensure these water supply emergency plans remain consistent and meet the goals provided in the guidance documents. With these plans in place, the retailers in the SAN BENITO URBAN AREA can adequately handle a water supply shortage due to a natural disaster or another interruption of the water supply (Cal EMA 1999).

The agencies' emergency shortage plans meet the requirements for the WSCP to include a seismic risk assessment and mitigation plan to assess the vulnerability of each water facility.

1.3. COMMUNICATION PROTOCOLS
Effectively implementing any stage of the water shortage contingency plan requires clear and timely communication with the public, stakeholders, key decisionmakers, and local, regional, and state governments. The WSCP Communication protocols allow agencies to efficiently communicate any current or predicted water shortages and the response actions that are triggered. Communication protocols are outlined for each stage. In order to ensure consistency, each agency is encouraged to develop scripted responses to commonly asked questions when each stage goes into effect and as information changes throughout a water shortage crisis.

1.3.1. Stage 1 and Prior Communication
Stage 1 contains voluntary measures meant to reduce water demand by up to 10 percent.

The SAN BENITO URBAN AREA agencies aim to communicate water conditions when a water shortage condition exists or is anticipated. During this stage, or when SAN BENITO URBAN AREA is expected to enter Stage 1 soon, the following communication protocols are recommended:
• The District, Hollister, Sunnyslope, SJB must communicate to establish consistent Stage 1 implementation and unified message in response to commonly asked questions (UWMP Section 8.5)
• Communication in both English and Spanish of voluntary actions with customers, residents, and businesses through social media, radio, websites, newspaper, television coverage, newsletters, and bill stuffers.
• Notification to stakeholders, elected officials, and other decision -makers regarding water shortage conditions, projections, actions to be taken, demand reduction goals, and implementation.
• Monthly reports will be sent to the Hollister and SJB City Council and the Sunnyslope Board of Directors. If reduction goals are not met, the respective managers will notify the governing board of each agency that additional action is required. • Direct contact (via telephone or email) with local media about conditions and response actions.
• Daily production figures will be reported to the Water Supervisor of each agency. • The Supervisor will compare the weekly production to the target weekly production to verify that the reduction goal is being met. Weekly reports will be forwarded respectively to the General Manager of Sunnyslope, the Public Works Director at the City of Hollister, San Juan Bautista City Manager and to the Program Manager of the Water Resource Association (WRA).
• Communication with public about potential for mandatory stages.

15 TODD GROUNDWATER

• Increased information about voluntary programs, like home surveys and leak repairs.

1.3.2. Stage 2 Communication
Stage 2 contains voluntary measures meant to reduce water demand by 10-20 percent.

During this stage, the following communication protocols are recommended:
• The District, Hollister, and Sunnyslope must communicate to establish consistent Stage 2 implementation and unified message in response to commonly asked questions (UWMP Section 8.5)
• Communication in both English and Spanish of mandatory actions and penalties with customers, residents, and businesses through social media, radio, websites, newspaper, television coverage, newsletters, and bill stuffers. • Notification to stakeholders, elected officials, and other decision -makers regarding water shortage conditions, projections, actions to be taken, demand reduction goals, and implementation.
• Direct contact (via telephone or email) with local media about conditions and new mandatory response actions.
• Direct contact (via telephone or email) to chamber of commerce and businesses directly affected by restrictions (hotels and carwashes, for example) • Monthly reports will be sent to the City Council and the Sunnyslope Board of Directors. If reduction goals are not met, the respective managers will notify the governing board of each agency that additional action is required. • Daily production figures will be reported to the Water Supervisor of each agency. • The Supervisor will compare the weekly production to the target weekly production to verify that the reduction goal is being met. Weekly reports will be forwarded respectively to the General Manager of Sunnyslope, the Public Works Director at the City of Hollister and to the Program Manager of the WRA. • Education about continued voluntary conservation actions with public. • Increased information about voluntary programs, like home surveys and leak repairs, particularly within context of adhering to Stage 2 mandatory restrictions.

1.3.3. Stage 3 Communication
Stage 3 seeks to reduce water demand by 20-30 percent but includes the same mandatory actions as Stage 2. During this stage, increased communication about water conditions can lead to a decrease in demand.

If reduction goals are not met, the respective managers will notify the governing board of each agency that additional action is required. • Increased information about voluntary programs, like home surveys and leak repairs, particularly within context of adhering to Stage 4 mandatory restrictions.

1.3.5. Stage 5
Stage 5 seeks to reduce water demand by 40-50 percent but includes the same mandatory actions as Stage 4. During this stage, increased communication about water conditions can lead to a decrease in demand.
• The District, Hollister, and Sunnyslope must communicate to establish consistent Stage 5 implementation and unified message in response to commonly asked questions (UWMP Section 8.5.7)
• Increased communication of mandatory actions and penalties with customers, residents, and businesses through social media, radio, websites, newspaper, television coverage, newsletters, and bill stuffers.
• Notification to stakeholders, elected officials, and other decision -makers regarding water shortage conditions, projections, actions to be taken, demand reduction goals, and implementation.
• Daily production reports will be provided to the General or City Manager of each agency.
• Direct contact (via telephone or email) with local media about conditions • Monthly reports will be sent to the City Council and the Sunnyslope Board of Directors. If reduction goals are not met, the respective managers will notify the governing board of each agency that additional action is required. • Warnings of increased water use monitoring and stricter mandatory restrictions if SAN BENITO URBAN AREA enters Stage 5.

1.3.6. Stage 6
Stage 6 is the most severe stage, seeking to reduce demand by at least 50 percent. The District, Hollister, and Sunnyslope must communicate to establish consistent Stage 5 implementation and unified message in response to commonly asked questions (UWMP Section 8.5.7).

1.4. COMPLIANCE AND ENFORCEMENT

1.4.1. Demand Reduction Through Public Outreach
During the most recent drought (2014-2016), public outreach was expanded by 200 percent, and a 25 percent reduction was achieved by both Hollister and Sunnyslope. These programs are discussed in more detail in Section 9 of the UWMP. The specific public outreach measures listed below are intended to reduce demand during a drought or water supply interruption:
• Expand Public Information Campaign — Newsletter and other flyers in both English and Spanish were used to publicize programs and explain the importance of drought conservation.
• Improve Customer Billing — Customers with higher than average bills were contacted and possible water savings were recommended.
• Offer Water Use Surveys — Both residential and landscape surveys help high water users to identify areas of potential conservation.
• Provide Rebates or Giveaways of Plumbing Fixtures and Devices — Rebates and plumbing retrofits are available at all times but are publicized more during drought conditions. Plumbing retrofits including hose nozzles, faucet aerators, and shower heads are available at no cost to customers. Rebates are available for low flow toilets and high efficiency washing machines.
• Provide Rebates for Landscape Irrigation Efficiency — There is currently a landscape efficiency rebate program that provides rebates for landscape conversion, low - volume sprinkler heads, rain sensors, hose timers, and includes customized sprinkler schedules.
• Increase Water Waste Patrols — Examples include: Implement a Water Waste Patrol program; Increase staffing for Water Waste Patrol; Increase authority of Water Waste Patrol.
• Moratorium or Net Zero Demand Increase on New Connections —The agencies have added a no new connection element to their WSCP that is triggered in Stage 4.

San Benito 2O25 UWMP
Water Shortage
Contingency Plan
2O TODD GROUNDWATER

• Implement or Modify Drought Rate Structure or Surcharge —a drought rate structure may be implemented in future droughts.

In addition to these measures, SAN BENITO URBAN AREA agencies offer ongoing educational programming, classes, and community outreach. Section 9 of the UWMP contains more detailed descriptions of these programs.

1.4.2. Warning and Citation Protocols
Enforcement is applicable at any water shortage stage. Any customer violating the regulations and restrictions on water use set forth in the "No Waste" Ordinances will receive a written warning for the first violation. A second violation within 12 months of the first violation results in a $100 penalty. On the third violation, the customer will be charged a $250 fine and the retailer may install a flow-restrictor. If a flow-restrictor is placed, the violator will pay the cost of installation and removal. After a fourth violation, a $500 penalty is issued. If water service is disconnected, it will be restored only upon payment of a reconnection charge. These penalties apply at any time but are likely to be more closely adhered to during drought periods.

Any willful violation occurring subsequent to the issuance of the second written warning will constitute a misdemeanor and may be referred to the City/County District Attorney's office for prosecution pursuant. Misdemeanor convictions could include imprisonment and/or fines. The length of time for imprisonment and the magnitude of the fine vary between Hollister and Sunnyslope. If water service is disconnected, it will be restored only upon payment of a reconnection charge. These penalties apply at any time but are likely to be more closely adhered to during drought periods. In addition to fines, the City, Sunnyslope or the District, after written notice, may install a flow restrictor device or discontinue service to consumers who willfully violate provisions of this WSCP.

A person or property can apply for a waiver to the requirements in the WSCP. This hardship waiver is applicable at any stage of the WSCP. The written request must be submitted to one of the SAN BENITO URBAN AREA agencies with supporting documentation (photographs, maps, drawings, and any other information as appropriate). The waiver may be granted or conditionally granted only upon a written finding of the existence of facts demonstrating an undue hardship to a person using water or to property upon which water is used. The Agency that receives the waiver must act upon any completed application no later than ten days after submittal and may approve, conditionally approve, or deny the waiver. The applicant requesting the waiver must be promptly notified in writing of any action taken.

1.5. LEGAL AUTHORITIES
In the event of a water shortage, the SAN BENITO URBAN AREA Agencies shall declare a water shortage emergency in accordance with Water Code Chapter 3 Division 1.

San Benito 2O25 UWMP
Water Shortage
Contingency Plan
21 TODD GROUNDWATER

Water Code Chapter 3 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.

The SBUA agencies shall coordinate with the cities of Hollister and San Juan Bautista and San Benito County for the possible proclamation of a local emergency, as defined in the California Government Code, California Emergency Services Act (Article 2, Section 8558).

1.6. FINANCIAL CONSEQUENCES OF WSCP
During periods of water shortage, revenue of the SBUA agencies may be reduced as the WSCP is implemented. Decreased water demand will lead to decreased revenue at the normal billing rate. The WSCP calls for an increase in water demand reduction programs, such as expanded public information campaigns, water use surveys, rebates, and water waste patrols, which may result in increased spending and staff costs.

The SAN BENITO URBAN AREA agencies proactively prepare for periodic revenue shortages and periods of increased spending. All surplus revenues that the District, Hollister, and Sunnyslope collect are currently reinvested into the water supply system in preparation for potential revenue reduction during water shortages.

Based on projected and observed declines in revenue during shortages, the entities determined that rate increases may be needed in Stage 2 through 6. In Stage 1, no additional water purchases and no rate increases are required. For Stages 2 & 3, 4 & 5, and 6, rate increases may be needed if the agencies decide to maintain the same revenue over this period.

1.7. MONITORING, REPORTING, AND WSCP REFINEMENT

PROCEDURES
Under normal water supply conditions, potable water production values for Hollister and Sunnyslope are recorded daily and reported monthly to the Water Supervisor. Water use will be monitored and analyzed through billing data. During a Stage 1, Stage 2, or Stage 3 water shortage, daily production figures will be reported to the Water Supervisor of each agency. The Supervisor will compare the weekly production to the target weekly production to verify that the reduction goal is being met. Weekly reports will be forwarded respectively to the General Manager of Sunnyslope, the Public Works Director at the City of Hollister and to the Program Manager of the WRA. During a Stage 4, 5, or 6 water shortage, the daily production report will be provided to the General or City Manager of each agency. In Stages San Benito 2O25 UWMP
Water Shortage
Contingency Plan
22 TODD GROUNDWATER

1 through 6, monthly reports will be sent to the City Councils of Hollister and SJB and the Sunnyslope Board of Directors. If reduction goals are not met, the respective managers will notify the governing board of each agency that additional action is required.

The WSCP implementation can be refined and updated at any point. During a water shortage, the Agencies may make changes as needed to best fit the emergency and communicate these changes with the public and stakeholders. After a water shortage emergency has passed, the Agencies are encouraged to evaluate the plan's effectiveness and may choose to adjust the WSCP to enhance its success, clarity, and feasibility.

1.8. SPECIAL WATER FEATURE DISTINCTION
Per Water Code Section 10632 (b) the SBUA Agencies shall define and analyze water features that are artificially supplied with water, such as ponds, places, waterfalls, and fountains, separately from swimming pools and spas. Water features that are not pools or spas may use recycled water, while potable water must be used in pools and spas for health and safety purposes.

1.9. ADOPTION, SUBMITTAL, AND AVAILABILITY
The initial WSCP adoption coincided with the 2015 UWMP adoption. The WSCP will be adopted again along side of the UWMP for the 2025 cycle. In accordance with section 10642 of the Water Code and section 6066 of the Government Code, each agency held a public hearing prior to adoption of the Plan.

Typical residential water usage in the United States is on the order of 300 to 500 gallons per residence per day, or 100 to 150 gallons per capita per day. Although these amounts can typically be significantly reduced during crisis situations, Sunnyslope County Water District has found it useful to develop an estimate for the quantity of supplemental water required for a number of potential outage scenarios. These estimates are as follows:

The City of Hollister maintains a potable community water system that is capable of supplying water to Sur yslope County Water District during an emergency.

During Normal operations, the exchange of water is as required by demand and metered through a series of five inter -ties between the City of Hollister and the Sunnyslope County Water Distribution 09/01/09

Systems. This exchange includes the routine daily transfer of the City of Hollister's share of water from the LESSALT Water Treatment Plant. Additional flows to and from the Sunnyslope Distribution System are based on seasonal water supply demands.

These inter -ties typically involve pressure reduction valves, water meters and a booster pump station at one location with associated appurtenances.

A higher water pressure in the Sunnyslope County Water District Distribution System results in Hollister's share of LESSALT surface water to flow through the Sunnyslope Fairview Pressure Zone primarily through the Santa Ana and Hillcrest Pressure Reducing Valve Inter -ties. Flows can vary from 0 to 1000 GPM but typically are between 400-600 gallons per minute (GPM) range at Santa Ana and 100-300 GPM range at Hillcrest, Sunset and Sunnyslope. Seasonal demands also allow Sunset and Sunnyslope inter -ties to provide LESSALT water to the City.

Water can be transferred into the Sunnyslope system using the City of Hollister's booster pump station at Hillcrest and Memorial Drive or Airline Highway City Well 46 to pump water against the pressure gradient. The demand in the City's sub system west of Memorial Drive is first met then surplus water will flow back to the Sunnyslope system through the Sunset, Sunnyslope and Hillcrest inter -tie connections.

The San Benito County Public Works Inter -tie provides water from the Sunnyslope Ridgemark Water Pressure Zone though a series of pressure reducing valves to the City of Hollister Cienega.

Pressure Zone. Transfer at this site typically falls within the 0-300 GPM range depending on seasonal demands.

4. Standardized Emergency Man
SHIMS
The Standardized Emergency Management SystemfNational Incident Management System (SEMS/NIMS) is the system required by Government Code §8607 (a) for managing response to multi -agency and. multi -jurisdiction emergencies in California. The system was created for several purposes. First, it allows rapid and effective coordination at the field level using the Incident Command System (ICS) to manage, multi -agency response to an incident. Ser_-nndly, SEMS/Ni11'1S create a common management structure at all levels of response, which allows entities to work with common terminology, staffing organizations, and facilities for more efficient interagency coordination. Thirdly, it creates an ordering process for requesting resources from the field through local government, to the County (Operational Area) to the state and eventually the federal government. It also allows each level of organization to track requests and resources that are dispatched to the incident or necessary for support. Local public agencies (cities, counties, special 09/01/09

districts) must use SEMS/NIMS to be eligible f©r State funding of certain response -related personnel costs resulting from a disaster. State agencies are required by the law to utilize SEMS/NIMS during emergencies.

NOTE: Depending on the circumstances of the incident, when a request is made by the water system to local first response agencies, such as Fire or Law Enforcement, ICS will be implemented by these first response agencies to manage the resources at the site. Water system personnel that will interface with these response agency personnel, in the field, should understand their role in the ICS structure. Water systems can and will provide tactical and precautionary measures through their Emergency Operations Center or the Water Utility Emergency Response Manager (WUERM). It will be important to coordinate these activities with the field (Incident) through an Agency Representative or Technical Specialist in the ICS structure.

Water System Personnel may function in the ICS structure (Field Level) as an Agency Representative or Technical Specialist.

Five Principle Furzclions of SEMS7NIIIIS
Ii ariagement - In a Water System Emergency Operations Center (EOC), the EOC Director has overall responsibility for all emergency functions. This person may initially be designated as the Water Utility Emergency Response Manager (WUERM) prior to the activation of an EOC. The EOC Director may retain and/or delegate authority for functions listed below.

In the field, under ICJ, an Incident 'L u1IIrllandei or Unified Ce, i inand is established u.epending on statutory authorities for the incident. The Incident Commander's responsibility is the overall management of the incident.

Operations s - The Operations Section is responsible for the management of ali operations directly applicable to the primary mission. established for the response. The Operations Section Chief activates and supervises organization elements in accordance with the Incident Action Plan and directs its execution.

For water utilities, coordinates emergency response activities at the water utility EOC level and implements the priorities established by management or the Incident Command, Operation Section staff include field coordinators, as necessary, linked to water utility personnel at other fixed facilities or assigned to incidents within the water utility. The field coordinator should receive and pass information up the chain of command, as well as, receive and coordinate requests for services and support.

Plannin2/Intelligence - Oversees the collection, evaluation, verification, and display of current information related to the emergency,. This section is also responsible for preparing action plans and maintaining documentation related to the emergency.. The information collected is needed to 1) understand current situation 2) predict probable course of the incident events 3) prepare alternative strategies and control operations for theincident.

Logistics - Provides facilities, services, and material in support of the Incident. Oversees the acquisition, storing, and distribution of essential resources and. support services needed to 09/01/09

Emergency/Disaster Response Plan
(SEMS-NIMS)
manage the emergency. It tracks the status of resources. Logistics provides services to all field units in terms of obtaining and meeting their personnel, materials and equipment needs including communications.

Finance/Administration - The Finance/Administration Section is responsible for all financial, administrative and cost analysis aspects of the incident. Finance/Administration prepares vendor contracts, maintains records of expenditures for personnel and equipment, and maintains records and processes claims. It also provides preliminary estimates of damage costs and losses.

General Staff - Each firnction listed above should have a delegated Chief to manage the Section.

Depending on the nature and scope of the emergency, each Section can have several branches, divisions, groups, or units.

Command Staff - These positions report directly to and are directly subordinate to the Incident Commander or EOC Director. They are the Public Information, Liaison and. Safety Officers.

Water Utility Emergency Operations Center
Depending on the Magnitude of the Incident, Water Utilities may have to establish an Emergency Operations Center (EOC) to manage its resources and coordinate with outside entities. An EOC is a physical location from which support for centralized emergency management can be performed.

The essential functions necessary in the Water Utility EOC are described below:
♦ Establish an EOC Director to manage the Operations, Planning/Intelligence, Logistics,.

Finance/Administration Sections, and related sub -functions. ♦ Setting Priorities and developing Action Plans
♦ Coordination and support of all field level incident activities within the utility service area,
♦ Information gathering, processing, and reporting within the utility service area and to other levels of SEMS/NIMS
♦ Coordination with local goverment, operational areas, or regional EOCs as appropriate. ♦ Requesting Resources from higher SEIVIS/NIMS levels
Note: In general, at any level of activation, the Water Utility Emergency Response Manager (WUERIVI) should be aware of the following incident management principles:
♦ Establishing objectives and priorities for the incident ♦ Establish an Incident Action Plan (waitten or verbal) ♦ Awareness of his or her responsibility for the 5 primary fiunctions of SEMS/NIMS ♦ Management, Operations, Planning, Logistics and Finance/Administration ♦ Ensure an effective span of control (only supervise 5-7 staff directly on an incident) ♦ Delegate authority and activate organizational elements within an Incident Command Structure only as necessary
♦ Provide for personnel accountability and a safe environment for staff ♦ Ensure effective communications

Sunnyslope County Water District
Emergency/Disaster Response Plan
(SEMS-NIMS)
Drinking Water Field Operations Branch - Chain of Command The primary contact for the water system during any emergency is their District Engineer. Water Systems should contact their District Engineer in the event of any emergency. From the District Engineer, authority moves up the line to the Regional Engineer, Branch Chiefs, Assistant Division Chief, to finally the Chief of the Division.

Emergency Operations Center
The Sunnyslope County Water District office (3570 Airline Highway) has been designatedas the communication network Emergency Operations Center (EOC). (The designated backup Emergency Operation Center is the LESSALT Water Treatment Plant at 1391 Fairview Road) All District vehicles contain copies of the SSCWD Emergency Response Plan & Operation and Maintenance Procedures Manual. Emergency contact information for equipment suppliers is located in section "SSCWD Employee Phone List" of this manual. The telephone and. FAX will be the primary mode of communication in an emergency, In addition, all District vehicles have Motorola Radios for inter company communication and the local fire department and law enforcement have a radio and SSCWD has made anTangements to use it to contact police, fire and other emergency response personnel should telephone communication be lost.

Personnel Accountability
The Suimyslope County Water District Emergency Operations Center (EOC) is designated as the personnel assembly area. During catastrophic emergency situations outside of working hours all personnel will first respond to personal emergencies then will report to the Emergency Operations Center. During working hours, personnel will communicate with the Emergency Operations Center to report their status and receive instructions. If an employee fails to report their status, an investigation into the location and safety of that employee will be initiated.

Family members are urged to contact the EOC for personnel updates and assistance.

Response Procedures
Personnel will, as quickly as possible, assess damage to water and wastewater system facilities, provide logistics for emergency repairs, monitor progress of repairs and restoration efforts,. communicate with health officials and water users according to the "Emergency Notification Plan" on file with the regulatory agency (i.e., Department of Public Health Services (CDPH) and document damage and repairs.

Other Agency Coordination
Coordination procedures with goverrunental agencies for health and safety protection; technical, legal, and financial assistance, and public notification procedures are continually being developed and updated through regulation and experience and will be added as necessary to this plan. 09/01/09

Sunnyslope County Water District
Emer ency/Disaster Response Plan
(SEMS-NIMS)
During an emergency, it is important to contact and notify all the appropriate agencies and. stakeholders that will be affected by the emergency. Some agencies will need to be notified immediately while others may be needed later in the incident, depending on the event. The following is a list of agencies and stakeholders that a water system should have updated contact information, Since this list has many contact names and phone numbers, this information should be reviewed annually to ensure that current information is provided.

The initial notification response to any emergency should be to "911" for the needed first responder and then to the Department of Public Health Services -Drinking Water Program. The Department of Public Health Services — Drinking Water Program is the Drinking Water Primacy Agency in California and has regulatory jurisdiction over all public water systems in the state.

Contact to the CDPH-DWP should be to their District Engineer, If the water system is unable to contact the District Engineer (or one of their staff), the water system should use the California Office of Emergency Services (OES) Warning Center Phone Number: 1-800-852-7550, which is a 24/7 phone number, A second phone number for the OES Warning Center is 916-845-8911. A duty officer will answer the CA OES Warning Center phone call and refer to statewide emergency phone 'numbers. In order to assist the duty officer -it will expedite response if you request the California Department of Public Health Services (CDPH) duty officer. The CDPH duty officer will then call management staff in the Drinking Water Program to respond to the emergency.

Depending on the magnitude of the event, the following state agencies may also need to be contacted:
6 Office of Emergency Services (OES) Warning Control Center. 6 Department of Water Resources,
6 Department of Fish and Game.
6 Regional Water Quality Control Board.
6 Department of Toxic Substances Control.

5. Initial Notifications
First Responders
911 - If the situation is an emergency that needs response from local fire, law enforcement, medical or hazardous materials team (HAZMAT), calling 91.1 should be the first immediate call.

Water system staff should be aware of where and how they are calling 911. If the water system staff call "911" from a cell phone, then the call is routed to the nearest California Highway Patrol Office, which may be in another city or county, and not in the immediate local 911 area. Typically, a direct phone number for the local 911 can be provided to the water system -contact your local first responders to get this phone number for cell phones.

Local Police and Sheriffs
Water systems should establish an ongoing relationship with the local police and sheriff offices that serve their service area. It is good practice to get therm familiar with water system facilities. If they are called out to an incident, they will then be familiar with some basic aspects of the water system.

Water systems that have large service areas that cover several cities or large areas should have contacts for each police and sheriff agency in their service area.

Fire and Hazzza
If the emergency incident involves an unknown substance and possible contamination of the water system, the first responders will more likely be the local fire department and/or HAZMAT team.

Most Hazmat teams are part of the local fire department, but some may be special teams under county or city. jurisdiction.

Like law enforcement agencies, water systems should know all the fire departments and/or HAZMAT teams that serve their service area and maintain contacts with those agencies. Contact your local county Office of Emergency Services to obtain the local HAZMAT teams that have jurisdiction in your area.

Drinking Water Primacy AQenct,
The Department of Public Health Services Drinking Water Program has regulatory jurisdiction for public water systems and should be one of the first agencies to be contacted in almost all emergency events. Contact should be to the District Engineer. In most emergency events, it is not appropriate to leave a message on the District Engineers voicemail. If the water system is not able to contact the District Engineer -they should call the State Warning Center 24/7 phone number as described in Section 6.3. The District Engineer will be able to assist the water system in:

Inspections of water treatment plants, storage facilities, watersheds (chemical contamination, sewage spills, erosion, and drainage diversions). 09/01/09

Sunnyslope County Water District
Emergency/Disaster Response Plan
(SEMS-NIMS)
Hospital and Critical Care Facilities
It is important to know location and contact information for all the critical care facilities and hospitals in your service area, An emergency or contamination event in the water system can effect tlre operations of these facilities.

Customers
It is important that a water system be able to communicate with their customers. All means of communication need to be explored to effectively communicate with customers. The Water Quality Emergency Notification Plan (WQENP), as required under Section 11.6460, California Health and Safety Code, is a significant part of a water system plan to communicate with their customers. The WQENP should be included in the Appendix of the ERP. The WQENP is a standard form that contains specific information for the CDPH District Engineer and the County; Contact your District Engineer for the current WQENP form.

6. Response Procedures
Personnel will, as quickly as possible, determine the status of other employees, assess damage to water and wastewater system facilities, provide logistics for emergency repairs, monitor progress of repairs and restoration efforts, communicate with health officials and water users according to the "Emergency Notification Plan" on file with the regulatory agency (i.e., Department of Public Health.

Services (CDPH) or Local Primacy Agency (LPA)), and document damage and repairs.

7. Public Notice Procedures
Public notice procedures should be developed before the disaster and not during the event. Public notices are a significant part of communicating with customers, Standard public notifications for a water outage/low pressure problems, Boil Water Order (BWO), Unsafe Water Alert (UWA) or Do Not Drink Notices have been developed by CDPH for use during an emergency. Each utility will need to modify the standard forms with specific contact information and guidance to customers depending on the nature of the emergency event. In addition, water systems need to have copies of public notices in the appropriate languages used in their service areas.

A BWO, UWA or Do Not. Drink Notice can be issued by one, or a combination of the following agencies:

CDPH — Drinking Water Program (Designated personnel -District Engineer, Regional Engineer or Branch Chief).
• Local County Health Department (Designated personnel -County Health Officer or Director of Environmental Health Department for small water systems under county jurisdiction).
• Affected Water System (Designated personnel -responsible person in charge of the affected water system, i.e., Director of Water Quality, Manager, Director of Water 09/01/09

(SEMS-NTMJ<S)
Department, Director of Public Works, Owner, etc. The water systems ERP should identify the designated personnel in their ERP).

All public notifications (TWO,'UWA o Do Not Drink Notices) should be coordinated with. the CDPH District Engineer, County Environmental Health Department and the County Health Officer prior to issuing a public notice. However, any one of the three agencies should act inunediately to issue a BWO or UWA, if delays will jeopardize public health and safety. The CDPH District Engineer or the water system must notify the County Health. Department and the County Health Officer prior to or immediately after issuing a public notice. Notice must be given to a person, a message left on voicemail is not sufficient. Coordination. of this notification should be identified in the BRP. Whenever a BWO/UWA has been issued, the CDPH DWP also needs to notify two other CA Department of Public Health Services Agencies CDPH Food and Drug and CDPH Licensing and Certification. The CDPH DWP District Engineer will notify the other two CDPH agencies of the BWO/UWA issued,
fhe following standard public notices are provided in the Appendix of this manual.

Consumer Alert Diiriiw Water Outages or Periods of Low Pressure If a water system is experiencing power outages, water outages or low pressure problems, a consumer alert may be issued to the public. The notice provides consumers information on conserving water and how to treat the water with household bleach if the water quality is questionable,
Boil Water Order (BWO)
A BWO should be issued vilely. minimum bacteriological water quality standards cannot be reasonably assured. To assure public health protection a BWO should be issued as soon as it is concluded by the designated personnel that the water supply is or may be biologically unsafe.

Examples of these situations include:

1. Biological contamination of water supply system, including but not limited to:
6 Positive total or fecal coliform bacteriological samples; 6 Prolonged water outages in areas of ruptured sewer and/or water mains; 6 Failed septic tank systems in close proximity to ruptured water mains; 6 Ruptured water treatment, storage, and/or distribution facilities in areas of known sewage spills
Known biological contamination;
6 Cross -connection contamination problems;
Illness attributed to water supply,

2. Unusual system characteristics, including but not limited to:
6 Prolonged loss of pressure;
6 Sudden loss of chlorine residual;
6 Severe discoloration and odor;

Implemented due to treatment inadequacies.

Unsafe Water Alert (t]JVAl/"Do Not Drink"
In the event a water quality emergency due to known or suspected chemical (non -bacteriological) contamination to a water system a UWA or "Do Not Drink" should be issued. Water should not be used for drinking and cooking, but may be used for sanitation purposes. Examples of these situations include:

1. Known or suspected widespread chemical or hazardous contamination in water supply distribution, including but not limited to:
6 Ruptured water distribution system (storage tanks, mains) in area of known chemical spill coupled with loss of pressure;
6 Severe odor and discoloration;
6 Loss of chlorine residual;
6 Inability of existing water treatment process to neutralize chemical contaminants prior to entering the distribution system, 2, Threatened. or suspected acts of sabotage confirmed by analytical r°esuitsY rr,,hi ing but not limited to:
• Suspected contamination triggered by acts of sabotage or vandalism. d. Emergency use of an unapproved source to provide a supplemental water supply.

Unsafe Water Alert (UIVA)/"Do Not Use"
In the event a known or suspected contamination event to a water system, where the contaminate may be chemical, biological or radiological a UWA or "Do Not Use" should. be issued. Water should not be used for drinking, cooking, or sanitation purposes. Examples of these situations include:

Known or suspected widespread chemical or hazardous contamination in water supply distribution, including but not limited to
6 Terrorist contamination event.

The public information officer for a water system needs to be assigned before an emergency occurs, The water system public infonnation officer (PI.O) will need to coordinate with all the other agencies PIOs. If more than one agency is involved in an emergency, a joint information center (SIC) will probably be established. If a. BWO or UWA is issued, the water system should notify the PIOs in the EOC immediately.

Media Notification
Dealing with and notifying the media is one of the most significant communication tasks. Any dealing with the media during an emergency should come from one unified source -typically from the 09/01/09

(SEMS-NIMS)
EOC. If more than one source conununicates with the media, there will be conflicting information that will give the appearance all the agencies involved in the emergency do not know what they are doing. The media is a good way to communicate with water system customers. Boil Water Orders, Unsafe Water Alerts, and other public notices can be distributed through the media. Again, this is only effective if the information is coordinated through one source (the JIC) and one message is delivered to the public.

Cancellation of Public Notification
Once a BWO/UWA is issued, the only agency that can rescind the public notice is the drinking water primacy agency. CDPH DWP will not lift the BWO until two rounds, collected one day apart, of coliforni bacteria samples have been analyzed and the results are negative. The two sets of sample results should be faxed to the CDPH DWP District Office for final approval before rescinding the BWO. Special chemical sampling will be required to rescind an UWA, please contact the CDPH DWP District Office to determine required sampling.
6 See SSCWD public notices in Section "Public Notification" of this Manual.

8. Water Quality Sampling
NOTE: Laboratory protocols and procedures identified are still under development by Federal and State Agencies. This section will continue to evolve find updates will be provided as necessary.

During an emergency, there are several types of water quality sampling that may need to be analyzed depending on the actual event. If it is natural disaster, flood or power outage, sampling will probably only include bacteriological samples, turbidity and chlorine residual samples if the system is chlorinated, However, if the event is a terrorist act or contamination event, the sampling will. include a fitll scan of Weapons of Mass Destruction (WM➢) chemical, radiological and microbiological (unless the actual contaminant used is known), Laboratory Resources
In general there are four different types or ownership of laboratory facilities in California that can analyze drinking water samples, which are listed below:

1. Commercial/private laboratories

2. County Public Health Laboratories

3. State Department of Health Services Laboratories

4. Research Facility/Specialty Laboratories
In general, laboratories are grouped into two broad categories — chemical or biological. Chemical laboratories include: general environmental chemistry laboratories, radiological laboratories, and specialty laboratories that may be able to handle and analyze exotic contaminants, such as chemical weapons and radionuclides. Biological laboratories include: environmental microbiology 09/01/09

laboratories and the Laboratory Response Network (LRN) that typically analyze clinical samples for pathogens and select biotoxins.

CDPH Laboratory
The CDPH Sanitation and Radiation Laboratories Branch (SRLB) is organized within the Division of Drinking Water and Environmental Management (DDWEM). SRLB is the State's primary drinking water quality testing laboratory and is the only State laboratory capable of measuring environmental radiation. Its primary mission is to provide analytical services, reference measurements and technical support pertaining to the State's Drinking Water and Radiologic Health Programs.

SRLB has two laboratories. The Southern California Section is located in Los Angeles and performs microbiological, inorganic and organic testing in various water matrices, The Northern California Section, located in Richmond, carries out inorganic and organic analyses in water, and radiochemical testing in various environmental matrices in addition to water. The SRLB in conjunction with the CDPH Microbial Disease Laboratory (MDL) does microbiological analyses including biotoxins.

California ritual Aid Laboratory Network (CAMAL Net)
The CDPH SRLB, in conjunction with the water utilities, USEPA Region IX laboratory in Richmond, Lawerence Livermore National Laboratory, and the California Department of Water Resources, have formed a laboratory network, CAMAL Net, to address laboratory capacity issues associated with possible drinking water related contamination events. CAMAL Net establishes a triage system to process samples when water systems or commercial laboratory methods are not available or the water system lacks capacity within their own lab. The CAMAL Net system will not handle any samples where field screening indicates that the sample may contain a CDC listed WMD agent. The list of WMD agents can be found on the Centers for Disease Control and Prevention wehpage at http://www.bt.cdc.gov/ . Any request for analysis through the CAMAL Net system needs to be approved by the CDPH DWP District Engineer in your jurisdiction prior to collection of water quality samples to be processed.

Chemical Analysis Classification
The California. Department of Public Health. Services along with its stakeholders and federal partners are in the process of developing an algorithm to assist California water systems, public health agencies, law enforcement, and first responders with the identification of possible chemical agents in drinking water contamination events. A draft version has been developed and it is anticipated that a final version will be released in the near future. The final version will become an appendix to this document.

Biological Analysis Classifications
The LRN for Bioterrorism has ranked laboratories (Level A, B, C or D) based on the type of safety procedures they practice.
b Level A Lab uses a Class II biosafety (BSL) cabinet
d Level B Lab is a BSL-2 facility + BSL-3 safety practices Level C Lab is a BSL-3 facility
4 Level D Lab is a BSL-4 facility
Level A Labs are used to rule out and forward organisms. b Level. B Labs are used for limited confirmation and transport. 6 Level C Labs are used for molecular assays and reference capacity. 6 Level D Labs are used for the highest level of characterization.

Currently, in California there are: 28 Level A labs, 10 Level B labs, 2 Level C labs. The two Level C laboratories are the LA County Public Health Laboratory, Los Angeles, CA and the CDPH MDL in Richmond, CA. Lawrence Livermore National Laboratory is also a Level C laboratory, but access to them is restricted. The only Level D laboratories available in the LRN are the national laboratories, such as those at the Center for Disease Control and Prevention (CDC) and the Department of Defense. These laboratories test and characterize samples that pose challenges beyond the capabilities of the Level A, B, and C reference labs, and provide support for other LRN members during a serious outbreak or terrorist event. The most dangerous or perplexing pathogens are handled only at the Bio-Safety Level 4 laboratories at CDC and the U.S. Army Medical Research Institute of Infectious Diseases (USANIRIID).

During a natural disaster, flood, earthquake, fire etc., sample collection and analysis will be available to the water system by their normal laboratory resources. Sampling will primarily consist of regulatory bacteriological samples and turbidity to show that the system has been flushed out. The water system may also be collecting chlorine residual samples throughout the system with a field. chlorine test kit.

Terrorist Event/Contamination Event
Once a threat warning has occurred and the utility has deemed the threat confirmed, it will be necessary to collect water quality samples. The decisions made from the time of the threat warning to the time the threat is confirmed is specific to each individual event. This "credibility stage" as referred to in the EPA Response Toolbox may take the 'utility between 2 — 8 hours and should. involve consultation with local first responders, CDPH DWP (Drinking Water Primacy Agency), local Public Health Department and regional FBI office. 09/01/09
