BACKGROUND / ANALYSIS East Valley Water District (District) has set out to create a regionally beneficial recycled water project with the construction of the Sterling Natural Resource Center (SNRC). This aligns with California’s long-term water supply reliability plan of increasing the use of recycled water. A key regulatory step required prior to the official operation of the facility is authorization to discharge recycled water at the proposed location. This process is governed by Title 22, Division 4, Chapter 3, Section 60320.202 of the California Code of Regulations (Title 22). Once operational, the SNRC will produce disinfected tertiary recycled water from the District’s wastewater flows to assist the region in reducing its reliance on imported water and to retain water supplies higher in the watershed by recharging recycled water into the Bunker Hill-B Groundwater Management Zone. The District currently conveys its wastewater to the San Bernardino Municipal Water Department for treatment, where it undergoes secondary treatment and is ultimately discharged in the Santa Ana River lower in the watershed than the SNRC. The SNRC facility will have an initial capacity of 8 million gallons per day (MGD) and an ultimate capacity of 10 MGD and include preliminary treatment (bar screens, grit removal and drum screens), a membrane bio-reactor (MBR) with biological nitrogen removal, ultraviolet (UV) light disinfection, anaerobic digestion of solids, and a recycled water pump station. Title 22 governs how recycled water is discharged and used in California. These regulations are overseen by the State Water Resources Control Board and enforced by the Regional Water Quality Control Board, with the purpose of protecting the public water supplies from contamination by defining the monitoring, analysis, treatment, and application criteria. The Title 22 approval process requires a public hearing to provide information on the project and an opportunity for the public to comment. This hearing is to be conducted by the sponsoring agency, in this case the District, followed by additional action considered by the Regional Water Quality Control Board.

As the Project intends to discharge recycled water to infiltration basins to beneficially reuse the recycled water, the project is considered to be a Groundwater Replenishment Reuse Project (GRRP) by the State Water Resources Control Board (SWRCB) Division of Drinking Water (DDW) and Santa Ana Regional Water Quality Control Board (RWQCB). Pursuant to the Title 22 Water Recycling Criteria, the Project would require a Waste Discharge Requirements (WDR) and/or Water Recycling Requirements (WRR) (WDR/WRR) permit. Issuance of a WDR/WRR for a GRRP involves conditional project approval from DDW. This report supports the Project in compliance with the Water Recycling Criteria specified in the California Code of Regulations (CCR), Title 22, Division 4, Chapter 3 (CCR, 2014). Chapter 1 describes the background and goals of the Project. 1.1 Background The SNRC is a new groundwater replenishment project using recycled water that is being implemented by EVWD and Valley District for the purpose of maximizing use of recycled water and replenishing groundwater within the San Bernardino Valley Subbasin, while maximizing benefits to the Santa Ana River and the region. The SNRC will recharge to the Bunker Hill-B Groundwater Management Zone (GMZ), which is part of the Bunker Hill Subbasin, which in turn is part of the larger San Bernardino Valley Subbasin or San Bernardino Basin Area (SBBA). The reliability of water supplies is becoming an increasingly important consideration for the long-term health and economic wellbeing of communities throughout California. With increasing demand for water and more restrictions on water deliveries, it has become even more valuable for communities to consider means of recycling water and including recycled water in the overall water supply portfolio. Implementing this recycled water program would provide a new and reliable local water supply for the region, help the region manage groundwater levels in the Bunker Hill Subbasin, and help offset the need for increased amounts of imported water. The Project consists of a new wastewater treatment facility to treat wastewater generated within the EVWD service area and replenish the Bunker Hill-B GMZ. In addition to the wastewater treatment plant, the Project would include modifications to EVWD’s wastewater collection facilities to convey flows to the new recycled water facility, and a treated water conveyance and discharge system. Currently, EVWD conveys wastewater for secondary treatment at the San Bernardino Water Reclamation Plant (SBWRP), which sends its treated water for tertiary treatment at the Rapid Infiltration and Extraction (RIX) Facility and discharges to the Santa Ana River. The new SNRC wastewater treatment facility will also include solids processing on-site, including co-digestion of food waste received from the City of Highland and surrounding communities. The SNRC would produce disinfected tertiary recycled water for discharge to Weaver Basins, owned and operated by Valley District. At startup, the SNRC will treat 6 million gallons per day (MGD); however, the SNRC plant capacity and the WDR/WRR permit application is for discharge of up to 8 MGD. Key benefits that would result from using recycled water for groundwater recharge are summarized in Table 1-1. Chapter 1 East Valley Water District 1-2 Woodard & Curran Title 22 Engineering Report November 2021 Table 1-1: Key Project Benefits Benefit Category Benefit Description Water Supply Reliability Provides new source of water supply that is reliable, drought-resilient, and locally controlled Diversifies regional water supply portfolio Resource Management Provides year-round beneficial use for recycled water Promotes highest and greatest beneficial use of recycled water Integration/Synergies with Other Practices Augments current groundwater recharge practices employed by the San Bernardino Valley Municipal Water District and helps to manage groundwater basin levels Consistency with State Goals and Objectives Embraces State guidelines and policies relative to recycled water, groundwater management, and diversification of water supplies 1.2 Project Overview EVWD, in coordination with Valley District, the regional water supply and groundwater replenishment agency, is implementing the SNRC to produce recycled water from EVWD’s wastewater flows, to assist the region in reducing its reliance on imported water, and to retain water supplies higher in the watershed for regional benefit, including recharge of the Bunker Hill Subbasin. EVWD provides domestic water and wastewater services to unincorporated areas of San Bernardino County, the City of Highland, and to portions of the City of San Bernardino. A project vicinity map is shown in Figure 1-1. The SNRC will treat wastewater generated in the EVWD service area for beneficial reuse in the Upper Santa Ana River watershed. For the ultimate project, recycled water will be used to recharge the basin with approximately 11,000 acre-feet per year (AFY, or 10 MGD) of recycled water at the Weaver Basins. The Bunker Hill Subbasin is located within the larger SBBA and is made up of two sub-basins: Bunker Hill-A to the northwest and Bunker Hill-B to the southeast. The basin has experienced declining water levels due to declining local runoff and reduced imported water deliveries, resulting in increased groundwater pumping. EVWD currently conveys its wastewater for secondary treatment to the SBWRP, which sends its treated water for tertiary treatment to the RIX facility and then discharges it to the Santa Ana River lower in the watershed than the proposed Project. Instead, the Project will treat and reuse EVWD’s wastewater for beneficial use within the upper Santa Ana River watershed. The Project will also provide the local community with greater control over the cost of wastewater treatment, while producing a new supply of recycled water for local groundwater replenishment. The Project includes construction of a new wastewater treatment facility in the City of Highland, which will treat wastewater and produce Title 22 disinfected tertiary recycled water for unrestricted use, and conveyance pipelines to convey the recycled water to its discharge locations. The SNRC facility will have a maximum future capacity of 10 million gallons per day (MGD) and include preliminary treatment (bar screens, grit removal and drum screens), a membrane bio-reactor (MBR) with biological nitrogen removal, ultraviolet (UV) light disinfection, anaerobic solids processing, and a recycled water pump station. The SNRC plant will include anaerobic digesters for food waste co- digestion. Project facilities, including both wastewater and treated water conveyance alternatives, as well as groundwater discharge locations, are shown in Figure 1-2. Recharge of the treated recycled water was evaluated at multiple locations (City Creek, Redlands Basins, Twin Creeks Spreading Grounds, and Weaver Basins), with Weaver Basins ultimately selected for the SNRC project. The hydrogeologic evaluation of this site confirmed its ability to accept recycled water for groundwater replenishment purposes. Discharge to Weaver Basins will occur via multiple new discharge points/structures within the newly constructed basins located on Greenspot Road east of Weaver Street. Chapter 1 East Valley Water District 1-3 Woodard & Curran Title 22 Engineering Report November 2021 Figure 1-1: Vicinity Map Chapter 1 East Valley Water District 1-4 Woodard & Curran Title 22 Engineering Report November 2021 Figure 1-2: Project Facilities Chapter 1 East Valley Water District 1-5 Woodard & Curran Title 22 Engineering Report November 2021 This Title 22 Engineering Report addresses Phase 1 of this Project, which consists of up to 8 MGD discharge to Weaver Basins. This report documents necessary information in support of a WDR/WRR permit from the Santa Ana RWQCB and DDW. Future phases are currently in development and are not included in this Title 22 Engineering Report, but will be the subject of future addendum(s) to this report. Potential activities in Phase 2 include: • Recharge from SBWRP Tertiary Treatment System (TTS), delivered via the Santa Ana River (SAR) pipeline • Split discharge to Weaver Basins and Plunge Creek Basins or SAR Bottom 6/Dike D after 2030 Prior to implementing any of these changes, San Bernardino Municipal Water Department (SBMWD) and/or EVWD will complete the required submittals for review and approval by the regulatory agencies. SBMWD will prepare a Title 22 Engineering Report, Antidegradation Analysis, and a Report of Waste Discharge (ROWD) for the TTS portion of Phase 2. EVWD will prepare an addendum to the Title 22 Engineering Report, Antidegradation Analysis, and a revised ROWD if SNRC effluent is sent to recharge basins other than Weaver Basins. 1.3 Authority Prior to August 2018, EVWD provided sewer collection services in its sphere of influence. EVWD received approval from the Local Agency Formation Commission (LAFCO) for San Bernardino County to include wastewater treatment, reclamation and disposal to its services under Resolution No. 3276 issued in August 2018. EVWD now has the authority to collect, treat, reclaim and dispose of wastewater and is authorized to construct and operate the SNRC. Valley District, which provides water supply, groundwater replenishment, storm water and wastewater treatment and disposal services, is authorized to recharge groundwater. 1.4 SNRC Objectives The primary objectives of the proposed Project are to: • Treat and reuse wastewater for multiple beneficial uses within the upper Santa Ana River watershed to meet existing and future wastewater treatment needs within the EVWD service area. • Increase the use of recycled water to continue efforts toward resolving regional water supply challenges in a cost effective and environmentally responsible manner. • Increase groundwater replenishment opportunities in the Bunker Hill Subbasin with new local water resources. • Provide an administrative center that benefits the community in a manner that is compatible with neighboring land uses. • Increase local water supply operational flexibility within the San Bernardino Valley region to advance the integrated water management objectives of Valley District and the region. 1.5 Outreach and Coordination Consistent with the California Environmental Quality Act (CEQA), and in its role as the lead agency, Valley District and EVWD conducted an extensive outreach program to inform the community and receive input in the SNRC planning process. Prior to EVWD’s LAFCO approval in 2018, Valley District was the lead agency for the project. Multiple public hearings were conducted, and a Final Environmental Impact Report (EIR) was certified by Valley District on March 15, 2016, and by EVWD in its capacity as a responsible agency on March 23, 2016. Several public meetings were conducted during the initial planning and feasibility study phases of project development where the agencies presented information on project drivers, status, siting, schedule, and budget, while providing an opportunity for public input and Q&A. Furthermore, EVWD has distributed fliers with customer’s monthly bills to update customers on project status. There is also a project specific website outlining the planning process and project goals, as well as informing the community of public involvement opportunities and providing downloadable materials. Chapter 1 East Valley Water District 1-6 Woodard & Curran Title 22 Engineering Report November 2021 In July 2019, as lead agency, EVWD adopted Addendum No. 1 to the 2016 EIR, which evaluated specified operational changes to the SNRC facility—emergency operations and recycled water detention ponds, use of an adjacent parcel, and food waste facilities—that did not create new or increased environmental impacts beyond those analyzed and mitigated in the Final EIR. In January 2021, EVWD, as lead agency, adopted Addendum No. 2 to the 2016 EIR to allow recharge of SNRC-treated water at two additional recharge basin locations (including Weaver Basins) in the City of Highland and extension of the 2016 EIR-certified treated water conveyance pipeline system to the two new recharge basins. Neither of these changes created new or increased environmental impacts beyond those analyzed and mitigated in the Final EIR. 1.6 Purpose of the Engineering Report The objective of this Title 22 Engineering Report is to demonstrate how the Project complies with the California Code of Regulations (CCR) Title 22, Division 4, Chapter 3, Water Recycled Criteria. Sections 60323 and 60320.100(h) of these regulations requires that an Engineering Report be prepared and submitted to DDW and the Santa Ana RWQCB for approval prior to producing recycled water for reuse from a water reclamation plant. The purpose of this Engineering Report is to request regulatory approval for the Project and to form the basis for its WRR/WDR permit.

California State Water Resources Control Board, Division of Drinking Water (DDW) DDW administers California’s Drinking Water Program previously administered by California Department of Public Health (CDPH) and transferred to DDW on July 1, 2014. • Responsible for establishing criteria to protect the public health with regard to recycled water use. • Regulates Water Recycling Criteria contained in the CCR, Title 22, Division 4, Chapter 3 including regulations with specific criteria for groundwater recharge projects. • Holds public hearings on potable reuse projects and makes recommendations to the RWQCB for inclusion into the water recycling requirements, or project permit. Chapter 2 East Valley Water District 2-4 Woodard & Curran Title 22 Engineering Report November 2021 Santa Ana Regional Water Quality Control Board The Santa Ana RWQCB is responsible for overseeing surface and groundwater quality and establishing waste discharge requirements in the Santa Ana River Basin. • Enforces the Water Recycling Criteria established by DDW. • Incorporates recommendations of DDW into the water recycling requirements (permit) for projects. • Issues and enforces water recycling permits and requirements. 2.3 Regulatory Requirements 2.3.1 State Water Resources Control Board, Division of Drinking Water Requirements Prior to June 18, 2014, the Water Recycling Criteria in the CCR, Title 22, Division 4, Chapter 3 (CCR, 2014) included narrative requirements for planned groundwater recharge projects. The regulations required that recycled water must be at all times of a quality that fully protects public health and that DDW recommendations would be made on an individual case basis taking into consideration all relevant aspects of each project, including the following factors: treatment provided; effluent quality and quantity; spreading area operations; soil characteristics; hydrogeology; residence time; and distance to withdrawal. Since 1976, DDW issued numerous draft versions of more detailed groundwater recharge regulations that served as guidance for the six permitted projects in California prior to 2014: • Montebello Forebay Groundwater Recharge Project – surface spreading of tertiary recycled water, stormwater, untreated Colorado River water and State Project water (imported water) • Chino Basin Groundwater Recharge Project – surface spreading of tertiary recycled water and stormwater; • Alamitos Gap Seawater Intrusion Barrier – injection of full advanced treatment (FAT) recycled water and treated imported water; now using 100% AWT recycled water; • West Coast Basin Seawater Intrusion Barrier – injection of 100% FAT recycled water in 2013; • Dominguez Gap Seawater Intrusion Barrier – injection of FAT recycled water and treated imported water; plans for 100% AWT recycled water by 2017/18; and • Groundwater Replenishment System (GWRS) – injection and surface spreading of 100% FAT recycled water, expanded to 100 MGD in 2015. Final groundwater recharge regulations were adopted and went into effect June 18, 2014. The groundwater recharge regulations are organized by type of project: (1) surface application (surface spreading) and (2) subsurface application (injection or vadose zone wells). The SNRC Project proposes groundwater recharge via surface spreading. Surface applications may spread either disinfected tertiary-treated (filtered) recycled water or full advanced treated (FAT) recycled water. The Project will comply with all specified Title 22 Criteria and Groundwater Recharge Criteria as outlined in this Engineering Report addressing the following key issues: • Source Control. The municipal wastewater used as source water for the recharge project must be from a wastewater agency that administers an industrial pretreatment and pollutant source control program that has been enhanced to include chemicals specified by DDW and the RWQCB, and an inventory of chemicals that may be discharged to the sewer system in that area. The City of San Bernardino implements an effective regional pretreatment program which EVWD currently complies with. EVWD is in the process of adopting its own pretreatment program and will continue to comply with the approved pretreatment program in accordance with the Pretreatment Regulations in the Code of Federal Regulations (CFR), Section 40, Part 403. EVWD’s Chapter 2 East Valley Water District 2-5 Woodard & Curran Title 22 Engineering Report November 2021 program is focused on residential compliance due to the lack of industrial facilities within its wastewater collection service area. • Recycled Water Contribution (RWC) and Diluent Water Requirements. Recharged recycled water must be blended with diluent water to comply with the DDW-specified maximum RWC. For surface spreading projects, the initial maximum RWC allowed under the regulations is 20%, unless an alternative initial RWC is approved by DDW based on demonstration of the treatment processes preceding soil aquifer treatment (SAT) can reliably meet the total organic carbon (TOC) limit calculated for the proposed maximum RWC. Diluent water is used to reduce the RWC. Typical diluent waters are potable water or water from a DDW- approved source (e.g., storm water, imported untreated water, or groundwater underflow). With the exception of potable water used for blending, diluent water must demonstrate compliance with drinking water standards for nitrate, nitrite, and the sum of nitrate and nitrite; and a source water evaluation of the diluent source shall be conducted and approved by DDW. Diluent water quality must also comply with drinking water standards (primary maximum contaminant levels [MCL], secondary MCLs, and notification levels [NL]). In order to comply with the maximum RWC limit, diluent water may be blended (1) directly with the recycled water (e.g., in the same spreading basins or in storage tanks or piping), or (2) indirectly with the recycled water (e.g., in nearby spreading basins or as underflow within the “buffer zone” surrounding the recharge area, which is a three-dimensional area of restricted well development designated to provide the required underground retention time). • Pathogen Control and Multiple Barrier Requirements. With regard to pathogen control, the criteria require multiple barriers (at least three) be used from raw sewage to extracted, usable groundwater in order to achieve at least: o 12-log enteric virus reduction o 10-log Giardia cyst reduction o 10-log Cryptosporidium oocyst reduction Projects must suspend operation if the virus reduction achieved is less than 10-log or if the Giardia cyst or Cryptosporidium oocyst reduction achieved is less than 8-log. Each barrier must achieve a minimum of 1-log reduction and will not be credited for more than a 6-log reduction for each of the above pathogens. Underground retention time may be credited with 1-log/month for virus reduction. Barriers must be validated to receive credit for the log reduction using demonstration reports or challenge testing. Underground retention time must be verified using an added tracer study in order to receive credit for the full log removal (1 log/month). Depending on the method used for project planning purposes, the regulations give partial log-reduction credit for intrinsic tracer studies (0.67 log/month), numerical modeling (0.5 log/month), or analytical modeling (0.25 log/month). For demonstration purposes, retention time is defined as the time between when the water with the added or intrinsic tracer is recharged at the site and when water with either 2% of the tracer has reached the downgradient monitoring well, or 10% of the peak tracer value is observed at a downgradient monitoring well. The regulations require that a tracer study be initiated within three months of project start-up. For projects without FAT, filtration and disinfection are required to attain Title 22 disinfected tertiary effluent requirements and the underground retention time must be at least six months in order to be credited with 10- log Giardia cyst and 10-log Cryptosporidium oocyst reduction. Chapter 2 East Valley Water District 2-6 Woodard & Curran Title 22 Engineering Report November 2021 • Response Retention Time. RRT is the time recycled water must be retained underground to identify any treatment failure and implement actions so that inadequately treated recycled water does not enter a potable water system, including the plan to provide an alternative water supply or treatment. The minimum RRT is 2 months but must be justified by the project sponsor(s). The greatest of the horizontal and vertical distances reflecting the retention times required for Pathogen Control or for RRT establish the zone within which drinking water wells cannot be constructed (i.e., “buffer zone” that effectively establishes a boundary between potable and non-potable use of the groundwater basin). For planning purposes, the Groundwater Replenishment Reuse Project (GRRP) regulations allow use of modeling to estimate residence time for project facility siting. A project sponsor must validate retention time using an added tracer or a DDW approved intrinsic tracer within the first three months of operation. • Total Organic Carbon Requirements. The Title 22 Water Recycling Criteria include provisions for increasing the maximum RWC based on the recycled water total organic carbon (TOC) concentration. The maximum allowable TOC concentration is established by the following equation: TOCmax = 0.5 mg/L ÷ RWC For surface spreading projects, the point of TOC compliance may be in the (1) undiluted recycled water or within the percolation zone, (2) diluted percolated recycled water adjusted for dilution, or (3) undiluted recycled water with a DDW-approved SAT factor, demonstrating TOC removal using SAT. For example, the TOCmax for a surface spreading project operating with an initial RWC of 20% would be 2.5 mg/L. Compliance with the TOC limit is based on weekly samples (as a minimum frequency) and a 20-week running average of all TOC results as well as the average of the last four TOC results. • Total Nitrogen (N). An MBR system alone or in combination with SAT should be able to produce a recycled water that meets the total N of 10 mg/L. However, the nitrogen requirements may be more stringent based on the Basin Plan groundwater objectives. If the project is discharging levels of nitrogen greater than the ambient groundwater quality and/or greater than the Basin Plan objective, an anti-degradation analysis is required. • Drinking Water Standards. An MBR system alone or in combination with SAT will produce recycled water that meets primary and secondary MCLs, with the exception of secondary MCLs for salts. The regulations allow compliance with secondary MCLs in the recharge water, which is the combination of recycled water and credited diluent water. Compliance with primary MCLs is based on the running annual average of quarterly samples. For those primary MCLs with acute toxicity (e.g., perchlorate), compliance is based on the running four-week results. For secondary MCLs, compliance is based on a single annual sample. Recharge water may be monitored in lieu of recycled water where the recharge water is comprised primarily of recycled water or a dilution factor is applied (i.e. recharge water monitoring may be applicable to disinfection byproducts in some cases). Recycled water and groundwater from the downgradient monitoring wells must also be monitored for priority toxic pollutants and chemicals specified by DDW. 2.3.2 Regional Water Quality Control Board Requirements Valley District and EVWD’s service area is located within the jurisdiction of the Santa Ana RWQCB. The Santa Ana RWQCB is one of nine regional boards under the SWRCB and has the responsibility for regulating recycled water discharges to groundwater and surface water that are subject to state water quality regulations and statutes. The RWQCB’s mission is “to preserve, enhance, and restore the quality of California’s water resources, and ensure their proper allocation and efficient use for the benefit of present and future generations.” Locally, the RWQCB implements policies and regulations, develops long-range plans, issues water recycling and waste discharge permits, and takes enforcement actions against violators of State and federal environmental regulations. Chapter 2 East Valley Water District 2-7 Woodard & Curran Title 22 Engineering Report November 2021 Basin Plan Waste Discharge Requirements (WDR) issued by the Santa Ana RWQCB are required to implement applicable State water quality control policies and plans, including water quality objectives and implementation policies established in the Water Quality Control Plan for the Santa Ana River Basin (Region 8) (Basin Plan) (RWQCB, 2011). The Basin Plan designates beneficial uses of surface water and groundwater resources in the watershed and sets water quality objectives that must be attained to protect these beneficial uses and conform to the State’s anti-degradation policy. The Basin Plan also designates well implementation policies as well as monitoring and assessment programs. Discharges to groundwater must be of sufficient quality to not impact beneficial uses. Table 2-1 shows the beneficial uses for the Basin. Table 2-1: Beneficial Uses in the Basin Plan in the Upper Santa Ana River Area Beneficial Use Bunker Hill Groundwater Basin Municipal (MUN) X Agricultural Supply (AGR) X Industrial Service Supply (IND) X Industrial Process Supply (PROC) X X Existing or Potential Beneficial Use In 2014, the Santa Ana RWQCB adopted an amendment to the Basin Plan that updated the 2004 Salt Management Plan (Resolution R8-2014-0005). In 2018, the Santa Ana RWQCB adopted Resolution R8-2018-0027, which accepted the TDS and nitrate-N groundwater management zones ambient water quality determinations as required in the Salt Nitrogen Management Plan. In 2021, the Santa Ana RWQCB adopted Resolution R8-2021-0020, which accepted the updated 2018 TDS and nitrate-nitrogen ambient management zone water quality determinations and assimilative capacity findings. Table 2-2 shows the current water quality objectives, ambient water quality, and assimilative capacity for TDS and Nitrate-Nitrogen (Nitrate-N) for the Bunker Hill-B subbasin. As shown in the table, there is assimilative capacity for TDS and nitrate-N in Bunker Hill-B. Table 2-2: Water Quality Objectives, Ambient Water Quality, and Assimilative Capacity in the Bunker Hill-B Groundwater Subbasin Constituent Water Quality Objective (mg/L) 1997 Ambient (mg/L) 2003 Ambient (mg/L) 2006 Ambient (mg/L) 2009 Ambient (mg/L) 2012 Ambient (mg/L) 2015 Ambient (mg/L) 2018 Ambient (mg/L) Assimilative Capacity (mg/L) TDS 330 260 280 280 270 280 290 280 50 Nitrate- Nitrogen 7.3 5.5 5.8 5.4 5.4 5.6 5.8 5.8 1.5 Excerpt from Attachment B3. Sources: RWQCB, 2021; SAWPA, 2020; RWQCB, 2018 The Basin Plan addresses antidegradation for groundwater recharge of recycled water in terms of how the discharge of recycled water and diluent water compare to the ambient water quality. If the concentration is at or below (i.e., better than the current ambient TDS and nitrate quality), then the discharge will not be expected to result in a lowering of water quality and no antidegradation analysis will be required – TDS and nitrate groundwater objectives are expected to be met. If the discharge exceeds the current ambient TDS and/or nitrate ambient quality, then the RWQCB would require the discharger to conduct an antidegradation analysis to demonstrate whether and to what extent the discharge would result in a lowering of ambient water quality (e.g., the extent, if any, the discharge uses available assimilative capacity). If the discharger demonstrates that no lowering of water quality would occur, then antidegradation requirements would be met, water quality objectives would be achieved, and the RWQCB could permit such discharges to proceed. If the analysis indicates that a lowering of current ambient water quality would occur, other than on a minor or temporally or spatially limited basis, then Chapter 2 East Valley Water District 2-8 Woodard & Curran Title 22 Engineering Report November 2021 the discharger would have to demonstrate that: (1) beneficial uses would continue to be protected and the established water quality objectives would be met; and (2) that the resultant water quality would be consistent with maximum benefit to the people of California; and, (3) that best practicable treatment or control (BPTC) has been implemented. 2.3.3 State Water Resources Control Board Requirements There are two policies of particular importance with respect to groundwater recharge projects for protection of water quality and human health: (1) antidegradation policies, and (2) the Recycled Water Policy. Antidegradation Policies California’s anti-degradation policies are found in Resolution 68-16, Policy with Respect to Maintaining Higher Quality Waters in California, and Resolution 88-63, Sources of Drinking Water Policy. These resolutions are binding on all State agencies. They apply to both surface waters and groundwaters, protect both existing and potential uses, and are incorporated into RWQCB Basin Plans. • Resolution 68-16 (Antidegradation Policy): The Antidegradation Policy requires that existing high water quality be maintained to the maximum extent possible, but allows lowering of water quality if the change is “consistent with maximum benefit to the people of the state, will not unreasonably effect present and anticipated use of such water (including drinking), and will not result in water quality less than prescribed in policies.” The Antidegradation Policy also stipulates that any discharge to existing high quality waters will be required to “meet waste discharge requirements which will result in the best practicable treatment or control of the discharge to ensure that (a) pollution or nuisance will not occur and (b) the highest water quality consistent with maximum benefit to the people of the State will be maintained.” • Resolution 88-63 (Sources of Drinking Water Policy): The Sources of Drinking Water Policy designates the municipal and domestic supply (MUN) beneficial use for all surface waters and groundwater except for those: (1) with TDS exceeding 3,000 milligrams per liter (mg/L), (2) with contamination that cannot reasonably be treated for domestic use, (3) where there is insufficient water supply, (4) in systems designed for wastewater collection or conveying or holding agricultural drainage, or (5) regulated as a geothermal energy producing source. Resolution 88-63 addresses only designation of water as drinking water source; it does not establish objectives for constituents that threaten source waters designated as MUN. Recycled Water Policy The Recycled Water Policy was adopted by the SWRCB on February 3, 2009 and became effective on May 14, 2009. It was subsequently amended on January 22, 2013 with regard to Contaminants of Emerging Concern (CEC) monitoring with an effective date of April 25, 2013. The Policy was a critical step in creating uniformity in how RWQCBs were individually interpreting and implementing Resolution 68-16 for water recycling projects, including landscape irrigation projects and groundwater recharge projects. In December 2016, the SWRCB adopted Resolution No. 2016- 006, updating the Science Advisory Panel’s recommendations for CEC monitoring in recycled water and updating the Recycled Water Policy to consider changes since 2013. On December 11, 2018, the State Water Board adopted Resolution No. 2018-0057, amending the Recycled Water Policy. The critical provisions in the Policy are discussed in the following subsections. • Salt Nutrient Management Plans: The 2009 Recycled Water Policy requires Salt Nutrient Management Plans (SNMPs) to be developed for every groundwater basin/sub-basin by May 2014 (May 2016 with a RWQCB-approved extension). The Santa Ana RWQCB adopted an SNMP in 2004, which was amended in 2014 (Resolution R8-2014-0005). • RWQCB Groundwater Requirements: The Recycled Water Policy does not limit the authority of a RWQCB to include more stringent requirements for groundwater recharge projects to protect designated beneficial uses of groundwater, provided that any proposed limitations for the protection of public health may only be imposed following consultation with DDW. The Recycled Water Policy also does not limit the authority of a Chapter 2 East Valley Water District 2-9 Woodard & Curran Title 22 Engineering Report November 2021 RWQCB to impose additional requirements for a proposed groundwater recharge of recycled water that has a substantial adverse effect on the fate and transport of a contaminant plume (for example those caused by industrial contamination or gas stations), or changes the geochemistry of an aquifer thereby causing the dissolution of naturally occurring constituents, such as arsenic, from the geologic formation into groundwater. This provision requires additional assessment of impacts of a groundwater recharge of recycled water project on areas of contamination in a basin and/or if the quality of the water used for recharge (for example low salinity) causes constituents, such as naturally occurring arsenic, to become mobile and impact groundwater. • Antidegradation and Assimilative Capacity: Assimilative capacity is typically defined as the difference between the ambient groundwater concentration and the corresponding groundwater quality objective. As the Bunker Hill Basin has an accepted Salt and Nutrient Management Plan, 2018 Recycled Water Policy Section 8.2.3 applies: “the antidegradation analysis may be based, in part, on the technical findings of the accepted salt and nutrient management plan as described in 6.2.2.” • CECs: As part of the Recycled Water Policy, a Science Advisory Panel was formed to identify a list of CECs for monitoring in recycled water used for groundwater recharge and landscape irrigation. The Panel completed its report in June 2010 and recommended monitoring selected health-based and treatment performance indicator CECs and surrogates for groundwater recharge of recycled water projects. The groundwater recharge monitoring recommendations were directed at surface spreading using tertiary recycled water (specifically monitoring recycled water and groundwater) and injection projects using reverse osmosis (RO) and advanced oxidation processes (AOP) (specifically monitoring recycled water). The Recycled Water Policy was amended by the SWRCB on January 22, 2013 to include the CEC monitoring program and the Office of Administrative Law approved the Amendment on April 25, 2013. The Amendment provides the final list of specific CECs and monitoring frequencies for groundwater recharge projects and procedures for evaluating the data and responding to the results. The requirements for groundwater recharge projects will be incorporated into the permits for existing groundwater recharge projects and will be included as requirements for all future projects. The Panel was reconvened and modifications to the CEC monitoring requirements are included in the 2018 Recycled Water Policy. In addition to revisions to the list of CECs to be monitored, potable reuse projects must also complete bioanalytical screening. As part of the final Groundwater Recharge Regulations, DDW has its own CEC requirements and monitoring locations that must be met in addition to the Recycled Water Policy requirements. 2.4 CalRecycle Requirements – Methane Emission Reduction In September 2016, Governor Brown signed into law Senate Bill (SB) 1383 (Lara, Chapter 395, Statutes of 2016), establishing methane emissions reduction targets in a statewide effort to reduce emissions of short-lived climate pollutants in various sectors of California's economy. SB 1383 establishes targets to achieve a 50 percent reduction in the level of the statewide disposal of organic waste from the 2014 level by 2020 and a 75 percent reduction by 2025. CalRecycle was granted regulatory authority to achieve the organic waste disposal reduction targets. The SNRC project includes food waste co-digestion in order to support the City of Highland and surrounding communities in meeting its organic waste reduction targets. 2.5 Environmental Compliance All public projects in California must comply with CEQA. Valley District prepared a CEQA-Plus EIR for the SNRC Project. The Notice of Preparation (NOP) was issued on October 16, 2015. The Draft EIR was released in December 2015 (ESA, 2015). The Final EIR was certified by Valley District on March 15, 2016 and EVWD on March 23, 2016 (ESA, 2016) and Notices of Determination were filed on March 16 and 24, 2016, respectively. Since the certification of the 2016 EIR, EVWD has taken over as lead agency for the SNRC Project. EVWD adopted Addendum No. 1 on July 24, 2019 and Addendum No. 2 on January 27, 2021. All Project facilities identified within this Engineering Report are covered by the scope of the certified Final EIR and the two Addenda. Chapter 3 East Valley Water District 3-1 Woodard & Curran Title 22 Engineering Report November 2021 CHAPTER 3: PROJECT FACILITIES The SNRC will be constructed with an initial capacity of 8.0 MGD, with an initial flow rate of 6.0 MGD. Anticipated build- out of the EVWD service area will require a future expansion of the SNRC to 10 MGD. EVWD will be responsible for the operation of the proposed SNRC. The Project is being implemented under a design-build alternative delivery method and construction began in early 2019 and is estimated to be completed in December 2022. An overview of the collection and treatment process are provided in this chapter. 3.1 Overview The SNRC is being constructed on two parcels in the City of Highland and will produce Title 22 recycled water for groundwater replenishment. Figure 3-1 shows a conceptual layout of the SNRC, including both the Treatment Facility and Administration Center. Treatment Facility. The Treatment Facility will provide tertiary treatment to wastewater generated within the EVWD service area, having an initial maximum capacity of 8.0 MGD to produce tertiary treated water in compliance with Title 22 recycled water quality requirements for unrestricted reuse. It will include an MBR, and UV disinfection. On-site solids handling would require an anaerobic digestion process followed by a thickener or screw press dewatering system. The SNRC plant will include anaerobic digesters for food waste co-digestion. All treatment processes will either be covered or housed in specific buildings equipped with noise and odor control facilities. Effluent that does not meet discharge standards for Weaver Basins will be sent to the onsite holding basin and/or Administration Center holding pond if secondary effluent criteria are met. If additional off-spec storage is needed, it will be routed offsite to an 8-MG capacity retention pond in the Weaver Basins facility. If secondary effluent criteria are not met, effluent will be re-routed back to the Treatment Facility headworks for further treatment. The SNRC would be sized for an initial maximum capacity of 8.0 MGD, with anticipated buildout capacity of 10 MGD. Administration Center. The 6-acre parcel west of North Del Rosa Drive will be developed with an Administration Center. The Administration Center will consist of administration buildings and pavilions for administrative offices needed for the treatment plant, surrounded by publicly accessible open space. The Administration Center will also include an interpretive center, which will also act as an Emergency Operations Center during emergencies, with community gardens, landscape pond, and pavilions. Signage will be provided at the onsite landscape pond. The administration buildings will be approximately 20,000 square feet equipped with offices, control systems, and meeting rooms. A large meeting room will be available for community functions. A parking lot with approximately 160 parking spaces will be constructed to accommodate the administration building routine operations as well as any community related events. The SNRC would be designed to integrate into the community with architectural features that would enhance the neighborhood. As shown in Figure 3-1, the Administration Center will utilize the recycled water in on-site landscape impoundments. Signage will be included along the walking trails and publicly accessible areas at intervals as specified by DDW. Treated Water Pump Station. The treated water pump station consists of the treated water pumps, electrical/control gear, potentially a hydro-pneumatic or surge tank outside of the building, above-ground piping, power transformers, and associated sidewalks and fencing. The pump station is co-located at the SNRC site and would likely house five 200-hp pumps. Groundwater Recharge Basins. The treated water pump station at the SNRC property would convey tertiary effluent from the SNRC to Weaver Basins, located on Greenspot Road approximately five miles from the SNRC treatment facility. Chapter 3 East Valley Water District 3-2 Woodard & Curran Title 22 Engineering Report November 2021 Figure 3-1: Conceptual Layout of SNRC Chapter 3 East Valley Water District 3-3 Woodard & Curran Title 22 Engineering Report November 2021 3.1.1 Anticipated Flowrates The anticipated flow data and peaking factors are presented in Table 3-1. The initial average capacity is anticipated to be 8.0 MGD. Table 3-1: Summary of Anticipated Flowrates and Peaking Factors Category Calculation Initial Capacity (MGD) Ultimate Capacity (MGD) Average Daily Flow, Dry Weather ADWF 8.0 10.0 Maximum Daily Flow ADWF x 1.5 12.0 15.0 Peak Daily Flow ADWF x 3.0 24.0 25.0 3.2 Wastewater Collection System Wastewater generated in the EVWD service area is primarily from residential and commercial uses. Negligible industrial wastewater is generated in the service area. Various wastewater collection system improvements are required within the EVWD service area in order to convey flows to the SNRC. Wastewater is conveyed by gravity to the SNRC. In 2018, the City of San Bernardino and EVWD agreed to flow swap, as shown in Figure 3-2, so that all flows conveyed to SNRC are gravity fed. In addition, several diversion points will be installed internal to the existing collection system to help capture and divert all of EVWD’s gravity fed wastewater flows to the SNRC facility. 3.3 SNRC Treatment Plant Facilities The following sections describe the SNRC treatment processes, staffing, and reliability features. The plant design will allow for efficiency and convenience of operation to permit the highest possible degree of treatment to be obtained under varying circumstances and will include the necessary alarms and process reliability requirements as required by Title 22. 3.3.1 Treatment Processes All treatment processes will either be covered or housed in a building with state-of-the-art odor control facilities. The SNRC will consist of treatment trains, each with a uniform capacity, and combined will have an initial capacity of 8.0 MGD. Space will be provided for additional trains, for an ultimate capacity of 10 MGD, to meet planned growth within the service area. The proposed treatment facility components described next are shown in the conceptual layout in Figure 3-1. Process flow diagrams for the liquid portion of the plant are shown in Figure 3-3 and Figure 3-4. Headworks Headworks will include preliminary screening and grit removal tanks. Influent screening will consist of two coarse screens with a maximum bar spacing of six millimeters (mm). Screenings will be diverted to a washer/compactor onsite then to a dumpster and trucked offsite to a permitted landfill. Two vortex-type grit tanks will be provided to remove grit from the liquid stream. The collected grit will be pumped to the grit washer/classifiers, then to a dumpster, from which a truck will transport the grit to a permitted landfill. The liquid stream will then pass through three cylindrical perforated fine screens with maximum openings of two mm. Screenings will be diverted to dumpsters and hauled off site to a landfill. Chapter 3 East Valley Water District 3-4 Woodard & Curran Title 22 Engineering Report November 2021 Figure 3-2: Flow Swap Between City of San Bernardino and EVWD Allowing Gravity Flow to SNRC Chapter 3 East Valley Water District 3-5 Woodard & Curran Title 22 Engineering Report November 2021 Figure 3-3: SNRC Simplified Process Flow Diagram Chapter 3 East Valley Water District 3-6 Woodard & Curran Title 22 Engineering Report November 2021 Figure 3-4: SNRC Process Flow Diagram Chapter 3 East Valley Water District 3-7 Woodard & Curran Title 22 Engineering Report November 2021 Equalization Basin Screened influent will flow either into the aeration basins via an influent mixing channel or a 1.07-million-gallon equalization basin. The equalization basin will be equipped with a compressed air large bubble mixing system to prevent solids settling. Flow from the equalization basin will be sent to the aeration basins with four 1,025-gpm capacity pumps, outfitted with VFDs, that discharge into the influent mixing channel. Membrane Bioreactor (MBR) System MBRs use the combination of a membrane process like microfiltration or ultrafiltration with a suspended growth bioreactor (aeration basins). When used with domestic wastewater, MBR processes can produce high quality effluent that can be reclaimed and is an approved Title 22 tertiary filtration technology. • Aeration Basins – Following the fine screens, the flow will pass through an influent mixing channel that distributes the flow to three aeration basins. Each aeration basin consists of six zones separated by baffle walls: anoxic zone 1, anoxic zone 2, aerobic zone 1, aerobic zone 2, aerobic zone 3, and a post-anoxic zone. Each anoxic zone holds approximately 110,500 gallons and each aerobic zone and the post-anoxic zone holds approximately 218,700 gallons. The anoxic and post-anoxic zones will be mixed with a compressed air large bubble mixing system, and the aerobic zones are equipped with fine bubble diffusers. • Membrane Tanks - The Project uses membrane units that are adjacent to the aeration basins. Air requirements for the membrane units will be used for air scour with four blowers. The MBR system will use citric acid, and sodium hypochlorite for clean-in-place cycles. The FPM500 FiberPlate2 Membrane Modules by Fibracast are the selected membrane modules. The membrane is a hybrid of flat sheet and hollow fiber technology that consists of PET (polyethylene terephthalate) sheets which are turned into PVDF coated panels with hundreds of hollow channels. Each membrane module contains 16 individual sheets. The membrane tank is fed at the bottom of the tank and return activated sludge will be pumped back from each train individually to a RAS return channel that spans the aeration basins. Ultra-Violet (UV) Disinfection The Project includes UV disinfection, which uses short wavelength UV light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA which leaves them unable to perform vital cellular functions. The system will consist of 2 channels with 5 duty and 1 redundant UV banks per channel. Section 3.3.5 provides a detailed description of the UV Disinfection System design. Treated Water Pumping Station The treated water pumping station includes a storage tank divided into two separate compartments: one storing the treated water intended for recycle and the other storing plant service water, which will be reused within the plant proper. Five 2,800 gpm capacity pumps will send treated water out of the facility. Each of these recycled water pumps will operate with variable frequency drives and therefore be able to cover the full range of flows expected from the treatment plant. The recycled water pumps will also send treated water to the compartment storing plant service water via an air gap connection to ensure no cross connection between the plant equipment and the recycle water. The recycled water pumping station will include a surge tank, a flow meter on the combined discharge header, and a composite sampler for water quality compliance. The service water compartment will include three pumps operating in a lead, lag, standby configuration to provide 100 psi of constant pressure to the plant service water system. Solids Handling EVWD will have solids handling facilities onsite at the SNRC, which will include anaerobic digestion of waste activated sludge (WAS) and thickening of undigested WAS. Processed solids will be trucked offsite for disposal. Food waste will be accepted from the City of Highland and surrounding communities, which will be co-digested with the SNRC sludge. Chapter 3 East Valley Water District 3-8 Woodard & Curran Title 22 Engineering Report November 2021 Sludge Thickening Three double drum rotary drum belt thickeners will be used to thicken the sludge from the MBR system. WAS will be pumped to the thickeners before going to the anaerobic digesters. Each thickener will be sized to process the maximum expected monthly sludge production assuming 9.6 hours per day operation, and thus providing full system redundancy. Under normal operating conditions, both units would be online operating at less than their design capacity, about 6.6 hours per day. Polymer will also be injected just upstream of the rotary drum thickener to aid in flocculation using online instrumentation to maintain the target polymer dose. Thickened WAS Dewatering and Offloading Screw thickeners will be employed for thickened WAS dewatering to a total solids concentration of at least 16 percent. Two decanter centrifuges will be provided, with each unit capable of processing the maximum month sludge production while operating at 8 hours per day, 5 days per week, including 1 hour for startup and shutdown. Three shaftless screw conveyors will transport the dewatered biosolids from the screw thickener discharge hopper to the dewatered biosolids haul truck. Biosolids will hauled offsite either to soil augmentation reuse facilities or to a landfill for disposal. Decant Treatment and Recycle The decant from the solids process is treated for ammonia removal via air stripping and acid addition and is then returned to the plant influent. Chemicals Used and Stored Onsite Chemicals will be used and stored onsite in compliance with hazardous materials storage and handling regulations. None of the proposed chemicals are classified as acutely hazardous. Odor Control The SNRC will be equipped with odor control systems to capture and treat foul smelling gases produced by raw wastewater and sludge before it is exhausted from buildings and tanks that process raw sewage or sludge. Solids handling facilities will also be equipped with high-rate ventilation systems necessary where these gases are present. Energy Requirements The SNRC will require electricity for the treatment processes and the treated water pumping station. The estimated power requirements for the treatment plant during average daily design flow is approximately 2882 kilowatts. Total annual power consumption for the treated water pumping station will be approximately 25,246,320 kWh per year. Electrical power will be supplied by Southern California Edison. Standby power will be installed on site to operate limited processes in the event of a power outage, which include influent pumps, aeration, MBR, disinfection and treated water pumps. Anaerobic Digestion and Cogeneration The SNRC will include anaerobic digesters and associated facilities for food waste co-digestion. Equal-sized anaerobic digesters will allow for volatile solids reduction, methane gas production, and stabilization of the thickened sludge. The SNRC will use the digester gas for cogeneration, which has a high concentration of methane. Cogeneration works by converting the methane to mechanical power and heat, which will be used for digester sludge heating. Facility Staffing The SNRC will be staffed with both operations and maintenance employees. A state-certified Grade V operator will be employed to supervise the operation of the plant. At this time, it appears that nine full time equivalent employees will be needed: six operators (one chief, one senior, two shift and two operators in training), two maintenance technicians and one administrative assistant. Chapter 3 East Valley Water District 3-9 Woodard & Curran Title 22 Engineering Report November 2021 3.3.2 Reliability Features The SNRC will comply with Title 22 Water Recycling Criteria and provide reliability by providing (1) standby units and equipment, (2) standby generator for emergency power, (3) equalization basin, an on-site retention basin and an offsite retention basin for short-term emergency storage and (4) online instrumentation to provide continuous monitoring for each treatment operation in the system. Standby and protective redundancy features are included for each treatment operation in the system. These are summarized in Table 3-2. Table 3-2: Redundancy Features by Treatment Operation The SNRC will utilize a raw wastewater equalization basin after screening and grit removal to dampen peak flow rates and balance the influent diurnal curve, which will allow for constant and optimum plant performance. Peak flows will not be retained in the collection system. The SNRC will utilize the onsite holding basin, onsite flow equalization basin, and offsite retention basin for emergency storage of off-spec water if treatment processes need to be corrected. The on-site storage basin has 2 MG of emergency storage capacity, and the flow equalization basin has 1.07 MG of emergency capacity. The offsite retention basin is located at the Weaver Basins facility and has 8 MG of capacity. This is a total of 11.07 MG of on-site and off- site storage, which meets the requirement in §60341 to have at least 24 hours of emergency storage. Flow from the off-site retention basins will be sent to the sewer to be returned to the SNRC influent for retreatment. If the SNRC effluent is off-spec for groundwater recharge but meets at least disinfected secondary-23 quality or better, EVWD may elect to discharge effluent to the landscape ponds per §60305(e). However, these ponds will typically only have approximately 0.3 MG capacity for additional effluent. The landscape ponds are lined to prevent groundwater recharge and include protective railings to deter public contact. The Treatment Facility control system will continuously monitor the operating parameters and vital functions of each treatment operation in the system. The output signals will be transmitted via the plant SCADA system to a central control station for monitoring by operations staff. If an out of compliance condition is detected, an appropriate alarm Treatment Operation Redundancy Feature Title 22 Reliability Requirements Cross-Walk (Article 10) Headworks Coarse Screens Standby Screen §60343(b) Grit Removal Standby Grit Removal Unit §60343(b) Flow Equalization Pumps Standby Pump §60343(b) Fine Screens Standby Screen §60343(b) MBR Membrane Filters Aeration Blowers Full Treatment Capacity with One Membrane Filter Train Out of Service §60345(a) and §60351(a) MBR RAS Pumps Standby Pump via Standby Train §60345(b) and §60351(b) Foam/WAS Pumps Standby Pump §60345(b) and §60351(b) UV Units Redundant Banks §60355 (in lieu of §60353) Recycled Water Pump Station Standby Pump §60355 (in lieu of §60353) Equalization Basins Emergency Storage (1.07 MG) §60341(e) and §60355 (in lieu of §60341(a) and (b)) On-site Holding Basin Emergency Storage (2 MG) §60341(e) and §60355 (in lieu of §60341(a) and (b)) Weaver Basins Off-Spec Retention Basin Emergency Storage (8 MG) §60341(e) and §60355 (in lieu of §60341(a) and (b)) Chapter 3 East Valley Water District 3-10 Woodard & Curran Title 22 Engineering Report November 2021 condition will be triggered to alert operations staff to take corrective action. If the out of compliance conditions escalates to an emergency condition (e.g., high-high alarm signaling emergency out of compliance condition), the control system may initiate an automatic emergency response action. This response would consist of the secondary- or MBR-treated water pump station automatically pumping treated effluent to the on-site emergency storage basin, while diverting raw wastewater or preliminary-treated effluent to the on-site emergency storage basin or equalization basin as the emergency diversion locations. Once the out of compliance condition is appropriately addressed and cleared, conveyance of raw wastewater into the plant headworks will resume and the treated water pump station will resume pumping treated effluent to its normal receptor location, thus restoring normal plant operations. A detailed discussion of plant alarms and reliability features will be provided as part of the required Operation Optimization Plan. 3.3.3 Preventative Maintenance Program EVWD will implement a preventative maintenance program which details each piece of equipment and a standard duration between inspections and the performance of routine maintenance in order to proactively prevent equipment failures. The specific measures for each treatment component will be provided as part of the required Operation Optimization Plan. 3.3.4 UV Disinfection System This section provides additional detail on the proposed UV Disinfection System for the project. Chapter 11 includes a discussion of the UV Disinfection System monitoring procedure. Following the MBR, the water will pass through UV disinfection treatment. The Design Build team selected the TrojanUVSignaTM UV disinfection unit. Information about this unit is included in Appendix B 1. Equipment layout and dimensions are shown in Table 3-3, and Figure 3-5 below. This system is an open-channel type with two channels, six duty and one standby banks, and 16 lamps per bank, as shown in Table 3-4. Peak design flow rate is 19 MGD, which is greater than the maximum daily plant influent flow expected of 12.0 MGD. The peak daily influent flow to the plant is 24 MGD but will be equalized and this flow is not expected to be seen at the MBR effluent / UV influent. Cleaning of the UV disinfection system will be automatically controlled by the process control system to maintain the required minimum UV dose. The SCADA system will vary the number of lamp banks that are operating, as well as the lamp intensity at which the banks are operating based on the influent flow and the UV transmittance in the UV influent distribution chamber. Following construction and prior to activation of the SNRC, the UV system will be tested to ensure that pathogen inactivation is achieved to the levels required by Title 22. A spotcheck bioassay test protocol will be developed consistent with NWRI 2012 UV Guidelines and submitted to DDW for review and approval. Upon receipt of approval, testing will be conducted in accordance with the finalized protocol. Testing will serve as the basis to demonstrate that the UV system performance is sufficient to allow DDW acceptance when operated to meet the requirements and conditions indicated in the conditional approval letter from DDW for the selected unit. This letter is included in Appendix B. The test results will be summarized in a report and submitted to DDW for review and approval. 1 The proposal from Trojan in Appendix B denotes a “Current Peak Design Flow” of 18.8 MGD, but recent refinement of the design has confirmed that the same system can provide the design dose at 19.4 MGD. Chapter 3 East Valley Water District 3-11 Woodard & Curran Title 22 Engineering Report November 2021 The UV PLC will interface with the Plant SCADA System. This will allow the SCADA to monitor the UV disinfection process. The UV control system will monitor and initiate alarms for the following: • Lamp Failure • Ballast Failure • Low UV Intensity • Reactor Failure • Reactor High Temperature • High Reactor Flow • Wiper Failure • Sensor Failure/loss of signal • Ground Fault Interrupter failure (1 Per each Power Distribution Center (PDC)) • Low Dose (low alarm at ≤ 84 mJ/cm2; low low alarm at ≤ 80 mJ/cm2) • Low UVT (≤ 65%) • Valve Fault • Communication fault High influent turbidity from the MBR will also cause an alarm and potential diversion event. Power supply interruptions will also trigger an alarm and shutdown. SNRC will have backup power provided by a diesel generator. Once the power interruption has been corrected then the system will be re-started and UV calibration confirmed.

Each UV channel will have water level controllers and downward opening weir gates to measure the water level and indirectly the flow that is used by the control system to control UV delivered dose and confirm that required dose is met. 2. Pers.Comm. Email from DDW, 1/31/17: “DDW recommends a low dose alarm at 84 mJ/cm2 and a low low alarm at 80 mJ/cm2. The UVT alarm should be set at 65%.” 3. Updated design for the TrojanUVSigna includes capacity for a peak design flow rate of 19.4 MGD.

The plan will discuss all the start-up activities to be conducted by the manufacturer and contractor and when these activities are to occur. The plan will be reviewed by the Owner and the Owner’s representative to ensure that the staging of the activities will occur at an appropriate time for the plant. For instance, the plan should have provisions regarding postponing start up during peak flow and solids loading events. After the UV manufacturer certifies that the equipment has been installed based on their specifications, then a series of startup and functional testing checks are conducted based on the requirements contained in the construction documents. Start-up Checks Before water is introduced into the UV system, a number of startup checks will be completed. The equipment/channels will be inspected and ensured that no foreign matter is in the Channel or reactor. In addition, comprehensive input/output checks will occur during the start-up activities. These checks are necessary to verify integrity and accuracy of signals between UV reactors, appurtenances such as gates, valves and analyzers, local control panels, master control panel, and any associated SCADA platform. Also, a check will be made of the status of each lamp and repair/replace as appropriate. Functional Acceptance Testing Functional acceptance testing will include activities that run the entire UV system through its "paces". This means ramping up and down of the flow, which should trigger the activation of additional banks and/or treatment trains, with associated closing/opening of gates and valves. Depending on actual flow variation as experienced by the utility, this may require the use of dummy signals to the control panels. Monitoring of the calculated dose, status of lamps, status of banks, power consumption, UV intensity, flow, UVT during this testing is important. It is particularly important to check that the calculated dose equation is correct and yields the correct dose under variable conditions as experienced during testing. Reliability Features The SNRC will comply with Title 22 Water Recycling Criteria and provide reliability by providing (1) standby units and equipment, (2) standby generator for emergency power, (3) short-term emergency storage in an on-site holding basin, equalization basin and off-site retention pond at Weaver Basins, and (4) online instrumentation to provide continuous monitoring for each treatment operation in the system. Sewer flows in excess of the plant’s treatment capacity will be treated via preliminary screening and then diverted to the equalization basin. The plant will be designed with SCADA system to monitor vital plant functions and provide alarms for loss of power and process failures. A summary of plant alarms and reliability features will be provided as part of the required Operation Optimization Plan. The UV PLC will interface to the plant SCADA System via Modicon Modbus communication protocol. This will allow the SCADA to monitor the UV disinfection process and other additional I/O. A list of available UV system status addresses will be supplied upon completion of programming. There will be a redundant Modbus link to SCADA supplied. All alarms generated by the SCC will be logged and displayed on the Operator Interface. Each alarm will be time and date stamped when it occurs. The 20 most recent alarms are recorded and displayed in the alarm history register. Chapter 3 East Valley Water District 3-15 Woodard & Curran Title 22 Engineering Report November 2021 Operations and Maintenance No specific operator certification is required for the operation of the UV disinfection system. However, on-site operations and training will be provided by Trojan staff to operators at SNRC. A System Operations and Maintenance Plan will be developed and will address the control system, alarm functions, records and reports. The plan will outline procedures and frequency for sleeve cleaning, lamp replacement and maintenance of system components and frequency for calibrating monitoring equipment. The location, access, and quantity of a backup supply of lamps and other critical components. Following is an anticipated list of the spare equipment: • UV Lamps: 10 percent of total installed UV lamps • Quartz Sleeves: 5 percent of total installed quartz sleeves • Ballasts: 10 percent of total installed ballasts • Sleeve Holder Seals: 10 percent of total installed sleeve holder seals • O-rings: 5 percent of total installed O-rings • Cooling Exhaust Fan: 1 • Reference UV Intensity Sensors: 2 • One spare for each type of SCC input/output module supplied and one spare input/output module for every 10 supplied • UV Transmittance Sensor/Monitor for On-line UVT Analyzer: 0 2 • UV lamp for On-Line UVT Analyzer: 03 No special tools are required to perform maintenance on the UV system. For safety, the following will be located at the SNRC for use by the operators while performing maintenance on the equipment: UV resistant face shield and cotton or Latex gloves. Contingency Plan Per Section 60323(c) of the Water Recycling Criteria, the following outlines contingency planning for the proposed SNRC facility. Following is a list of conditions which would trigger an immediate diversion of the product water to take place: • High Filter Effluent Turbidity – 24-hour total above 0.2 NTU exceeds 5% of 24 hours (or 72 minutes) and/or instantaneous turbidity exceeds 0.5 NTU for 10 seconds. • UV System Failure – Applied UV dose of less than 84 millijoules/cm2 and/or filtered effluent UV transmittance of less than 65%. 2 Pers.Comm. TrojanUV, Jordan Fournier, 2/1/17: “We do not recommend keeping a spare UVT sensor… If the sensor fails, the system will default to the design UVT.” 3 Pers.Comm. TrojanUV, Jordan Fournier, 2/1/17: “The HACH UVT Analyzer… does not have a lamp.” Chapter 3 East Valley Water District 3-16 Woodard & Curran Title 22 Engineering Report November 2021 The following alarms and power supply reliability features are included: • Lamp breakage (mercury release) – The UV unit will include a UV sensor/monitor for intensity measurement as outlined in the alarm section. The UV sensor/monitor will detect a drop in the lamp output from the lamp breakage and will immediately alarm and shutdown the UV System. • Low-low operation UV dose, low-low UV intensity, or high-high turbidity alarms - The UV unit will include a UV sensor/monitor which monitors operation UV dose, UV intensity and turbidity as outlined in the alarm section. The UV sensor/monitor will detect any of those three (3) alarm conditions and will immediately alarm and trigger a diversion of effluent discharge. • Failure of the upstream treatment process or UV disinfection system - The UV unit will include a UV sensor/monitor which will identify failure of upstream treatment process (typically high-high turbidity) and will immediately alarm and trigger a diversion of effluent discharge. • Power supply interruptions - The UV unit will include a PDC which will detect a power supply interruption and will immediately alarm and trigger a diversion of effluent discharge. • Activation of standby equipment including system and lamp start-up times – SNRC will have backup power via a diesel engine and generator. Once the power interruption has been corrected, the system will be re- started and UV dose delivery confirmed. Any of the conditions listed above will trigger shut down of effluent discharge to Weaver Basins and diversion to either the onsite holding basin, landscape ponds, the equalization basins, the offsite retention basin, and/or back to the headworks. 3.4 Recycled Water Conveyance and Discharge Facilities The recycled water conveyance system includes a treated water pumping station on the SNRC site and a 30-inch diameter conveyance pipeline network conveying recycled water to Weaver Basins to recharge Bunker Hill-B. A small portion of the conveyance line immediately adjacent to the SNRC site is 36-inch pipe that was formerly used as a potable water line. (See Figure 3-6). There are no additional customers or connections between the SNRC and the recharge area. However, there is a valve vault included for a potential turnout where the pipeline crosses City Creek on East 5th Street if this discharge location is approved in the future. The primary point of discharge will be Weaver Basins, providing recharge of the Bunker Hill-B Subbasin. A full operational plan is described in Section 6.4. The treated water conveyance pipeline will be installed within the public roadway rights-of-way (ROW) along East 6th Street heading east from the SNRC property for approximately five miles to Greenspot Road east of Weaver Street. Weaver Basins consists of five rectangular basins. Each basin is nine feet in depth and is sloped with the western bottom edge of each basin four foot lower than the eastern bottom edge. Discharge to Weaver Basins will occur via multiple new discharge points/structures within the newly constructed basins. The basin inlet piping includes an inlet isolation valve vault to the site and an inlet flowmeter. The piping will feed the basins from the north side of the site and each basin inlet has a motor-operated valve to control flow and to allow a basin to be removed from service. See Chapter 6: Recharge Basin Use Areas and Operations for a detailed description of the Weaver Basins. Chapter 3 East Valley Water District 3-17 Woodard & Curran Title 22 Engineering Report November 2021 Figure 3-6: Conveyance Piping from SNRC to Weaver Basins Chapter 3 East Valley Water District 4-1 Woodard & Curran Title 22 Engineering Report November 2021 CHAPTER 4: SOURCE WASTEWATER 4.1 Influent Wastewater Characteristics The characteristics of raw wastewater collected by the EVWD have not been historically monitored, since flows are treated at the SBWRP. EVWD conducted water quality sampling in April 2015 at sewer locations near the proposed influent pump station sites. The anticipated wastewater quality characteristics were developed in 2015 based on the limited sampling data and information contained in the 2013 Annual Monitoring Report for the City of Redlands WRF (City of Redlands, 2014) as shown in Table 4-1. The City of Redlands raw wastewater quality has been utilized since Redlands most nearly represents the range of primarily domestic wastewater sources similar to the wastewater sources in the EVWD service area.

Notes: “-“ = not analyzed, “ND” = non-detect 4.2 Industrial Pretreatment and Source Control Program The purpose of an industrial pretreatment and source control program is to prevent discharges into the collection system that may have an adverse impact on treatment process performance or create hazardous conditions that may damage facilities or endanger workers and the public. Very few sources of industrial discharges exist within the EVWD service area; however, development of a comprehensive program and implementation process is essential for the EVWD to provide a high level of service and protect public health. The City of San Bernardino implements an effective regional pretreatment program which EVWD currently complies with. EVWD will serve as the program administrator Chapter 3 East Valley Water District 4-2 Woodard & Curran Title 22 Engineering Report November 2021 responsible for all permitting activities and establishing local limits for discharge to the collection system in addition to EPA and RWQCB specified pollutants of concern. Appendix B contains the draft Pretreatment Ordinance and Enforcement Response Plan. EVWD intends to adopt these documents in fall 2021. While EVWD will not receive a NPDES permit for its discharge and is not subject to the federal pretreatment requirements in Title 40 CFR 403.8(f)(5), the draft program is based on federal requirements and includes an Enforcement Response Plan (ERP) as it is considered good practice to prepare one in order to meet the requirements of Title 22 CCR 60320.106. Compliance with DDW Groundwater Recharge Regulations The program will comply with the applicable regulations below: Title 22 Section 60320.106. Wastewater Source Control – “A project sponsor shall ensure that the recycled municipal wastewater used for a GRRP shall be from a wastewater management agency that: (a) administers an industrial pretreatment and pollutant source control program; and (b) implements and maintains a source control program that includes, at a minimum; (1) an assessment of the fate of Department-specified and Regional Board-specified chemicals and contaminants through the wastewater and recycled municipal wastewater treatment systems, (2) chemical and contaminant source investigations and monitoring that focuses on Department-specified and Regional Board-specified chemicals and contaminants, (3) an outreach program to industrial, commercial, and residential communities within the portions of the sewage collection agency's service area that flows into the water reclamation plant subsequently supplying the GRRP, for the purpose of managing and minimizing the discharge of chemicals and contaminants at the source, and (4) a current inventory of chemicals and contaminants identified pursuant to this section, including new chemicals and contaminants resulting from new sources or changes to existing sources, that may be discharged into the wastewater collection system.” Chapter 5 East Valley Water District 5-1 Woodard & Curran Title 22 Engineering Report November 2021 CHAPTER 5: RECYCLED WATER QUALITY 5.1 Estimated Treated Water Quality The SNRC will produce Title 22 disinfected tertiary recycled water for unrestricted use and will meet effluent water quality and discharge requirements set forth by the Santa Ana RWQCB. Effluent water quality data cannot be presented at this time since the Project facilities are not yet constructed and operational. However, many WRPs utilizing MBR treatment technology produce tertiary effluent today, and a number of studies have been performed to analyze the technology’s effectiveness in treating wastewater to such standards. The City of Redlands operates an MBR treatment system and Table 5-1 presents the anticipated water quality resulting from MBR treatment of the EVWD’s collected wastewater based on the City of Redland’s Water Reclamation Facilities (WRF) and input from MBR vendors.

Chapter 5 East Valley Water District 5-2 Woodard & Curran Title 22 Engineering Report November 2021 5.2 Pathogenic Microorganism Control Pathogen removal requirements for groundwater replenishment reuse projects (GRRPs) are established by DDW in the GRRP Regulations. The regulations require that recycled water used for groundwater recharge receives treatment that achieves at least 12-log enteric virus reduction, 10-log Giardia cyst reduction, and 10-log Cryptosporidium oocyst reduction. The treatment system must consist of at least three separate treatment processes where each process can be credited with no more than a 6-logs removal and must achieve at least a 1-log removal. For each month recycled water is retained underground, the project can be credited with a maximum 1-log virus removal. Based on a requirement for at least 7.5-log virus reduction via underground retention, the groundwater modeling results must show at least 15- log retention via particle tracking until the tracer study is completed and the underground retention time confirmed. For spreading projects, 10-log credit will be given for Giardia and Cryptosporidium if the Project meets Title 22 disinfected tertiary effluent and 6-months retention time. Process log removal credit can be based on information in the literature, previously conducted studies, and other information considered relevant by DDW. Table 5-2 presents a summary of the pathogen removal credits for the SNRC. The Project will achieve 5-log virus credit through tertiary treatment using the Australian Tier 1 MBR validation protocol and Equation 3.3 of the 2012 NWRI Guidelines for UV Disinfection. Modeled underground retention time is in excess of 15 months, which allows for 7.5- log credit for virus, Giardia, and Cryptosporidium. As the project is providing disinfected tertiary treatment and providing at least six months retention underground, 10-log credit for both Giardia and Cryptosporidium can be credited per §60320.108(c). The SNRC will meet the minimum required 12/10/10 log removal for pathogenic microorganisms. The basis for the log removal credits is discussed in Section 5.2.1. Table 5-2: Anticipated Project Log Removal Credits Pathogen MBR UV SAT1 Underground Retention Time Total Required Virus 1.02 3.53 - 7.5 12 12 Giardia 104 10 10 Cryptosporidium 104 10 10 Notes: 1. Soil aquifer treatment (SAT) is not included in the total. Underground retention time is determined on a monthly basis by DDW, which does not distinguish between SAT through percolation and travel retention time. If SAT were included, log removal would exceed the totals indicated. 2. Based on the Australian Tier 1 MBR validation protocol, provided the MBR operates within the required operating envelope of 0.2 NTU 95% of the time and diverts when effluent turbidity is greater than 0.5 NTU (WRF, 2021). 3. At a UV dose of 80 mJ/cm2, equation 3.3 (Log inactivation = (UV dose * 0.0368) +0.5464)) of the 2012 NWRI UV Guidelines can be used to determine the corresponding inactivation of MS2 based on the UV dose. A UV dose of 80 mJ/cm2 would be equal to 3.5-log virus inactivation. 4. Project will meet requirements for treatment (tertiary) and retention (6 months) to be credited with full 10-log reduction per §60320.108(c). 5.2.1 Anticipated Pathogen Reduction Membrane Bioreactor and UV Disinfection Credits MBR is the combination of a membrane process, like microfiltration, with a biological process, a suspended growth bioreactor. The MBR will be the primary method of treatment and first effect pathogen barrier. UV disinfection will be the final treatment barrier at the SNRC. The process is intended to inactivate and prevent growth of microbes in the SNRC effluent. The SNRC will utilize UV irradiation to achieve disinfection of the effluent. Chapter 5 East Valley Water District 5-3 Woodard & Curran Title 22 Engineering Report November 2021 Per the conditional approval letters for the UV units in Appendix A, DDW found that the validation testing and report demonstrated the ability of the UV Disinfection System to meet the minimum coliform and virus disinfection criteria found in Title 22 of the California Code of Regulations for recycled waters that have received treatment through an tertiary filtration process accepted by now DDW. This acceptance is based on the following condition: • The UV Disinfection System must be preceded by filtration meeting the definition of "filtered wastewater" under Title 22 Section 60301.320. The proposed SNRC MBR filtration process will meet Section 60301.320 requirements. Per NWRI’s Ultraviolet Disinfection Guidelines for Drinking Water and Water Reuse (NWRI, 2012), when using membrane filtration as part of the treatment train upstream of UV, the following performance criteria shall apply. DDW specifies these operating requirements. • The design UV dose shall be at least 80 mJ/cm2 under maximum day flow. • The filtered effluent UV transmittance shall be 65 percent or greater at 254 nm. • The effluent turbidity shall be no greater than 0.2 NTU 95% of the time, not to exceed 0.5 NTU. Per Title 22, disinfected tertiary recycled water is that which combines disinfection and filtration to “inactivate and/or remove 99.99% of the plaque forming units of F-specific bacteriophage MS2, or polio virus in the wastewater” (Title 22 §60301.230). Therefore, the MBR/UV treatment train will provide 5-log inactivation for virus. The design UV dose to meet Title 22 disinfected tertiary recycled water following membrane filtration (see Section 3.3.5 for UV design criteria) is based upon the required dose (mJ/cm2) to receive a 5-log reduction in virus when combined with filtration. As a consequence, at least 4-log reduction of Giardia and Cryptosporidium is also provided by the treatment system (WateReuse, 2015). Soil Aquifer Treatment Credit Soil aquifer treatment allows the percolation through the vadose zone in the soil to be used as a biologically active filter. Percolation through this zone provides approximately 4-log removal of bacteria, viruses, protozoa and significant reductions in TOC (Hogg et al., 2012). However, percolation through the vadose zone cannot be distinguished from the overall underground retention time, therefore no credit for pathogen log removal will be listed specifically for SAT. Underground Retention Time Credit Final pathogen removal is achieved within the aquifer, based on a credit of 1-log reduction per 1-month of underground retention for viruses if the retention time is demonstrated with an added tracer. Numerical modeling is only credited with 0.5-log/month. A minimum of 7.5-log removal is needed to meet 12-log virus removal target after accounting for MBR and UV, so a minimum 15 months of underground retention time must be demonstrated by numerical groundwater modeling. In addition, the regulations (Section 60320.108) grant 10-log removal of Giardia and Cryptosporidium for spreading projects if the Project meets Title 22 disinfected tertiary effluent and 6-months retention time as demonstrated with an added tracer (or 12-months retention time if demonstrated by numerical modeling). From the hydrogeological analysis (which applied numerical modeling), the underground retention time to the well closest to the Weaver Basins, Redlands N. Orange Well #1, is 2 years. [EVWD Plant No. 143, 147, 146, and 146A are municipal supply wells located closer to Weaver Basins (see Figure 9-1); however, these wells will be inactivated before recharge begins at Weaver Basins.] Based on numerical modeling, it is anticipated that the Weaver Basins recharge location will provide an underground retention time in excess of 15 months, for which DDW has allowed for 7.5-log credit for virus. Chapter 6 East Valley Water District 6-1 Woodard & Curran Title 22 Engineering Report November 2021 CHAPTER 6: RECHARGE BASIN USE AREAS AND OPERATIONS This section describes the groundwater recharge area and the proposed operational strategy. The Weaver Basins have recently started construction in October 2021. The hydrogeological analyses and groundwater impacts are provided in Chapter 10:. 6.1 Weaver Basins The Weaver Basins discharge location will be used for groundwater replenishment. The design consists of conveying up to 8.0 MGD of recycled water from the SNRC to the newly constructed Weaver Basins, which are located west of the intersection of Weaver Street and Greenspot Road, on a partially disturbed lot within the City of Highland. The site is surrounded by residential to the west and north; open space to the east; and the Santa Ana River on the south. Weaver Basins consists of five rectangular basins, as shown in Figure 6-1 and Table 6-1. Each basin is nine feet in depth and is sloped with the western bottom edge of each basin four foot lower than the eastern bottom edge. Bottom elevations of the basins, going from east to west, range from approximately 1,376 to 1,350 feet above mean sea level (msl). The basins are bounded by an earthen dike that is approximately 10 feet above existing land surface. Each adjacent infiltration basin is separated by an earthen berm approximately 5 feet in height. Figure 6-2 shows a portion of the P&ID that shows the valving and flowmeters on each basin (See Appendix F for the full P&ID sheet). The basin inlet piping includes an inlet isolation valve vault to the site and an inlet flowmeter. The piping will feed the basins from the north side of the site and each basin inlet has a motor-operated valve to control flow and to allow a basin to be removed from service.

GEOSCIENCE estimated the vadose zone travel time using the infiltration rate and the 2020 depth to groundwater at approximately 15 days. Table 6-2: Summary of Weaver Basins Discharge Facility Properties Effective Recharge Area (acres) Estimated Infiltration Rate (ft/day) Recharge Capacity (MGD) Depth to Groundwater (ft) Vadose Zone Travel Time (days) 15 7.6 37.1 113 15 Source: GEOSCIENCE, 2021. Table 3-1 6.2 Recharge Basin Use Area Containment Provisions The basins are designed to overflow from Basin 1 to Basin 5. In the event that all basins become full, the recycled water flow to the site can be directed to Weaver Channel. Under normal operating conditions, the valve that can direct flow to Weaver Channel is closed and must be operated manually. Chapter 7 East Valley Water District 7-1 Woodard & Curran Title 22 Engineering Report November 2021 CHAPTER 7: DILUENT WATER SOURCES As specified in the GRRP Regulations, the source of diluent water is to be identified and quantified for a groundwater recharge and replenishment program that uses recycled water. This Project is unique in that it uses groundwater underflow as the primary source of diluent water at the discharge/recharge location. Solute transport modeling (MT3DMS) was used to estimate RWC at locations downgradient of Weaver Basins. Additional information on these results and the quantity of underflow is provided in Chapter 10 and Appendix C. The primary source of diluent water is anticipated to include Santa Ana River water and imported water artificially spread at the existing Santa Ana River Spreading Grounds, located approximately two miles east of the Weaver Basins facility. Due to the direction of regional groundwater flow and Weaver Basins being located hydraulically downgradient from the Santa Ana River Spreading Grounds, diluent water is anticipated to reach Weaver Basins as groundwater underflow. Additional sources for groundwater underflow that may qualify as diluent water include the infiltration of natural and urban runoff that recharges the groundwater basin through either deep percolation from the ground surface or as inflow/underflow from areas outside the basin. 7.1 Water Quantity The amount of water available for underflow will change annually based on the amount of runoff and precipitation and the amount of water spread upgradient at the spreading grounds. Figure 7-1 shows that the model simulated water level prior to the project (labelled as “Baseline 66-90”) under Weaver Basins for the years 2022 through 2050 ranges from 75 feet below grade to 300 feet below grade. The Baseline 66-90 model simulation uses the Habitat Conservation Plan (HCP) Base Period of 1966-1990 with an average precipitation of 15.9 inches per year. Using the 1979-2014 Base Period, with an average precipitation of 16.2 inches per year, results in a model simulated water level under the basin of approximately 35 to 40 feet higher: 40 feet below grade to 260 feet below grade, as shown in Figure 7-2. In the RWC estimations using solute transport modeling, the HCP Base Period has been used to be conservative. However, this lower groundwater level allows for EVWD to spread more imported water either at Weaver Basins or at other spreading basins, except in the years shown where groundwater level is already predicted to be high (shown as 2026, 2036 and 2040 in Figure 7-1). Valley District is working to develop the Regional Recycled Water Pipeline that will connect the SNRC conveyance and the SBWRP. In addition to allowing recycled water flow from the SBWRP TTS to Weaver Basins, this pipeline can also be used to send SNRC effluent to the RIX plant in times of high groundwater in Bunker Hill-B near Weaver Basins. Chapter 7 East Valley Water District 7-2 Woodard & Curran Title 22 Engineering Report November 2021 Figure 7-1: Simulated Depth to Groundwater Under Weaver Basin under Model Base Period 1966-1990 (Average Precipitation: 15.9 inches per year) Figure 7-2: Simulated Depth to Groundwater Under Weaver Basin under Model Base Period 1979-2014 (Average Precipitation: 16.2 inches per year) Chapter 7 East Valley Water District 7-3 Woodard & Curran Title 22 Engineering Report November 2021 7.2 Water Quality The Bunker Hill Subbasin is generally calcium-carbonate type water. The triennial ambient TDS and Nitrogen recomputation for Bunker Hill Subbasin was recently completed through 2018. The figures applicable to Bunker Hill are included in Appendix D. The approximate location of Weaver Basins has been added to these figures for reference. Nitrogen near Weaver Basins ranged from 3.5 to 4.8 mg/L as N compared to the drinking water MCL of nitrate as N of 10 mg/L. TDS near Weaver Basins ranged from 170 to 236 mg/L compared to the drinking water secondary MCL of 500 mg/L. EVWD has several wells in the vicinity of Weaver Basins that can be used to estimate underflow quality, as shown in Figure 7-3. EVWD Wells No. 143 and 147 are located immediately to the south of the Basins and EVWD Wells No. 146 and 146A are located immediately downgradient of the basins. These four wells will be inactivated upon project start up, as they are located within the well control zone. EVWD Well No. 120 is located upgradient of the Basins and will not be affected by the project. Therefore, this well can be used to evaluate diluent quality on an ongoing basis. Well No. 120 is not currently in use as an active production well for EVWD and was last sampled in 2009. Water quality for these five wells is summarized in Appendix E. All five wells meet all primary and secondary MCLs. Figure 7-3: EVWD Wells Used to Determine Underflow Water Quality The Bunker Hill Subbasin has been long plagued by several major contaminant plumes consisting of various organic compounds found above the MCL: Crafton-Redlands (TCE/PCE/CBCP), Norton Air Force Base (TCE and PCE), Muscoy and Newmark Superfund sites (TCE and PCE), and Santa Fe plume (PCE, TCE and 1,2-DCE). Cleanup of the plumes has been ongoing for several years and includes the use of granulated active carbon (GAC) to treat extracted groundwater which is blended for municipal distribution. Figure 7-4 provides an overview of the plumes. These plumes are located to the south of the anticipated recharge area and are not anticipated to be affected by the project. Chapter 7 East Valley Water District 7-4 Woodard & Curran Title 22 Engineering Report November 2021 Figure 7-4: Overview of Plumes Chapter 8 East Valley Water District 8-1 Woodard & Curran Title 22 Engineering Report November 2021 CHAPTER 8: GROUNDWATER BASIN This section provides an overview of the groundwater basin characteristics. The hydrogeological analysis on the groundwater recharge impacts is provided in Chapter 10:. As described below, two court judgments, referred to as the Western Judgment (1969) and the Santa Ana River Judgment (1969), provide the overall framework for the division of rights and responsibilities for water users in the Santa Ana River basin. • Santa Ana River Judgment - Stipulated Judgment in Orange County Water District v City of Chino et al., entered April 17, 1969. • Western Judgment - Judgment in Western Municipal Water District (Western) of Riverside County et al., v East San Bernardino County Water District et al., entered April 17, 1969. 8.1 Surface Water Body Description and Management The Project area is in the Santa Ana River watershed, which drains from the steep slopes of the San Bernardino Mountains to the valley floor of the Inland Empire, through the Prado Basin and on to Orange County and the Pacific Ocean. The Santa Ana River travels 75 miles from its origins near Big Bear Lake to the Pacific Ocean. In the mountainous areas, perennial surface water exists in segments of the Santa Ana River and tributaries. Big Bear Dam impounds surface water high in the mountains. Below Big Bear, Seven Oaks Dam, built by the US Army Corps of Engineers in the 1990s, provides flood control protection to the urbanized valley below. From below the Seven Oaks Dam through the City of San Bernardino, the river is a soft-bottom channel that is generally dry in the summer but contains some seasonal flows in the winter and spring. Historically, the Santa Ana River likely exhibited perennial flows from groundwater upwelling; however, groundwater levels have declined since the 1800s eliminating perennial flows in much of the river. Several large tributaries join the river in San Bernardino County including City Creek, Warm Creek, Lytle Creek, Plunge Creek, Mill Creek, the Rialto Drain, and San Timoteo Creek. These tributaries are usually dry in the summer, responding only to storm events and spring runoff. Some of the smaller drainages exhibit perennial urban runoff, but these flows generally infiltrate into the ground prior to the confluence with the Santa Ana River in the San Bernardino County portion of the watershed. Downstream of the City of San Bernardino to the City of Riverside, the Santa Ana River flows perennially due to the discharges from wastewater treatment plants serving the upper valley cities including Highland, San Bernardino, Rialto, and Colton. Groundwater and urban runoff begin to enter the river as it flows past the City of Riverside. Downstream of Riverside, the river flows are increased by discharges from the City of Riverside and the City of Corona wastewater treatment plants. Near the City of Corona, the river flows through the Prado Reservoir and Dam through the Santa Ana Mountains and onto the Orange County Coastal Plain. Surface water rights are largely governed by the Santa Ana River Judgment, which imposes a physical solution requiring parties in the upper Santa Ana River watershed to deliver a minimum quantity and quality of water to points downstream, most notably at the Riverside Narrows and Prado Dam. This information is documented annually in the Santa Ana River Watermaster report. The Watermaster consists of five members, with responsibilities for administering the judgment and reporting annually to the court and representative agencies. The Santa Ana River Watermaster is composed of members from each of the four representative agencies. Valley District, Inland Empire Utilities Agency, and Western Municipal Water District (Western) nominate one member each to the Watermaster; Orange County Water District nominates two members. 8.2 Groundwater Basin Description and Management The Bunker Hill Subbasin, encompassing an area of approximately 120 square miles, consists of alluvial material and is bounded by the San Gabriel Mountains, San Bernardino Mountains, Crafton Hills as well as several faults including the Banning, Redlands, San Andreas, Glen Helen, and San Jacinto faults. The Subbasin is located within what is Chapter 8 East Valley Water District 8-2 Woodard & Curran Title 22 Engineering Report November 2021 referred to as the SBBA and stores approximately six million AF of water and is the primary water source for the EVWD service area. The Bunker Hill Subbasin is made up of two sub-basins: Bunker Hill-A to the northwest and Bunker Hill- B to the southeast. The Bunker Hill Groundwater Subbasin consists of alluvial materials deposited over igneous and metamorphic rocks. Alluvial deposits that make up the primary aquifers are separated into hydrogeologic units: upper confining member (UCM) and its water bearing zone (UWB); middle confining member (MCM) and its water-bearing zone (MWB), and lower confining member (LCM) and its water-bearing zone (LWB). The UWB and MWB units yield the largest quantities of water to pumping wells. The primary faults within the Bunker Hill Groundwater Basin are the San Andreas and San Jacinto fault zones. The San Andreas Fault Zone is located north of the Project area, at the front of the San Bernardino Mountains. The right to groundwater, along with an established mechanism to account for “foreign” water such a recharged recycled water, is paramount to the implementation of the Project. The Western Judgment generally defines the SBBA as the region above the San Jacinto Fault, while excluding Yucaipa, San Timoteo, Oak Glen, and Beaumont Basins. This area produces 71% of groundwater extracted from the Santa Ana Watershed and includes the Bunker Hill subbasins. 8.2.1 Western Judgement The Western Judgment identifies regional representative agencies to be responsible, on behalf of the numerous parties bound thereby, for implementing its replenishment obligations and other requirements. The representative entities are Valley District and Western Municipal Water District (Western). Valley District is solely responsible for providing replenishment of the SBBA if extractions exceed the safe yield of the Basin. The court-appointed Watermaster includes representatives from Valley District and Western. A summary of pertinent basin management information related to the Western Judgment is included below. • Plaintiff and Non-Plaintiff Agencies – The Plaintiffs in the 1969 Western Judgment were Western Municipal Water District of Riverside County, City of Riverside, Gage Canal Company, Agua Mansa Water Company, Meeks & Daley Water Company, and the Regents of the University of California, Riverside. San Bernardino Municipal Water District was the non-Plaintiff. • Natural Safe Yield – The natural safe yield was established at 232,100 AFY. The Plaintiffs’ (Western entities) rights are capped at 27.95% of the natural safe yield, or 64,862 AF, notwithstanding any Additional Extraction Agreements or “new conservation,” as defined in the judgment. The Non- Plaintiffs’ (Valley District entities) rights are unlimited provided that an equal amount of basin replenishment occurs to offset any amount that the Non-Plaintiff production exceeds—72.05% of the natural safe yield, or 167,238 AF. An annual report, entitled Annual Report of the Western-San Bernardino Watermaster, provides an “accounting” of basin extractions. • Replenishment – Valley District is responsible for replenishing the SBBA for that amount of Non-Plaintiff extractions exceeding 167,238 AF. The replenishment obligation may be met by any of the following means: o Return flow from excess extractions o Replenishment provided in excess of that required o Amounts extracted without replenishment obligations (i.e., Additional Production Agreement) o That amount of water extracted below the natural safe yield o Return flow from imported water • New Conservation – This is defined in the Western Judgment as “any increase in replenishment from natural precipitation which results from operation of works and facilities not now in existence.” The judgment contemplated that the parties would develop facilities that would result in the capture of more natural runoff. Chapter 8 East Valley Water District 8-3 Woodard & Curran Title 22 Engineering Report November 2021 The construction of the Seven Oaks Dam within the Santa Ana River has provided such an opportunity, and Valley District and Western are seeking to obtain a water right from the SWRCB and to construct the facilities necessary to capture Santa Ana River water that was not historically captured. The parties under the Western Judgment will have their adjusted extraction rights increased to include a proportionate share of any New Conservation, provided that each Plaintiff party pays its proportionate share of the costs to develop said New Conservation. As a non-plaintiff party to the Western Judgment, EVWD was allotted production rights of 14,217 AFY. The Judgment states that EVWD may pump more than this to meet demands, while Valley District is responsible for recharging the basin. Through implementing a groundwater recharge recycled water project, EVWD will be contributing to basin recharge along with Valley District, which will provide an opportunity for this contribution to be credited to Valley District towards their current obligation (RMC, 2014; 2015a), therefore offsetting supplies currently utilized for groundwater recharge. 8.2.2 Seven Oaks Accord The 2004 Seven Oaks Accord calls for Valley District and Western to recognize the prior rights of water users for a portion of the natural flow of the Santa Ana River. In exchange, the water users agreed to withdraw their protests to the Santa Ana River Water Right Applications for Supplemental Water Supply submitted by Valley District and Western to gain additional appropriations of Santa Ana River water. The Seven Oaks Accord requires Valley District and Western to develop a groundwater spreading program in cooperation with other signed parties, including EVWD. The program is intended to maintain groundwater levels at specific wells in the region. This prompted local agencies to include groundwater management in the Upper Santa Ana River Integrated Resource Management Plan and collectively prepare an annual Regional Water Management Plan since 2008. 8.3 Basin Characteristics 8.3.1 Geology Weaver Basin is located in north-central Bunker Hill-B groundwater management zone in a structural depression located between the San Gabriel Mountains, San Bernardino Mountains, Crafton Hills, and between several faults. The depth to bedrock in the vicinity of the proposed recharge basin is estimated at approximately 500-900 ft below ground surface. There are no faults which may act as a barrier to groundwater flow known to occur in the vicinity of Weaver Basin. The primary faults located in Bunker Hill-B are located approximately one-mile upgradient and to the east, along the base of the foothills. Horizontal flow barriers representing Faults L and K, simulated by the Refined Basin Flow Model (RBFM), are located approximately a half to one mile west of the proposed recharge site. 8.3.2 Groundwater Flow Groundwater in the area of the Weaver Basin generally flows by gravity drainage westward paralleling the Santa Ana River. There are no indications that any of the known or otherwise postulated faults within the Bunker Hill Subbasin act as barriers to groundwater flow within the Weaver Basin area. 8.3.3 Summary of Aquifer Characteristics Table 8-1 provides an overview of aquifer characteristics near the Weaver Basins discharge.

Chapter 9 East Valley Water District 9-1 Woodard & Curran Title 22 Engineering Report November 2021 CHAPTER 9: PRODUCTION WELLS No new production wells are being installed as part of this project. This chapter details the existing production wells in the vicinity of the Weaver Basins. Any impacts on the wells are detailed in Chapter 10. 9.1 Wells near Weaver Basins The nearest active down gradient municipal supply wells to the Weaver Basins recharge location are the City of Redlands N. Orange Wells #1 and #2, as summarized in Table 9-1 and Figure 9-1. EVWD Plant No. 143, 147, 146, and 146A are municipal supply wells located closer to Weaver Basins (see Figure 9-1); however, these wells will be inactivated before recharge begins at Weaver Basins. Farther downgradient are municipal supply wells EVWD Plant No. 132-5, 141, 151, and 28A, which are all three to four miles from Weaver Basins. CEMEX is regulated as a San Bernardino County Department of Public Health (DPH) public water system and its active Well No. 01 is located approximately 12,000 feet downgradient of the project. CEMEX also has a non-potable well used for washing aggregate approximately 1,500 feet east of Redlands N. Orange Well #2. However, this well is outside of the area affected by the project per both particle tracking and solute transport modeling. The non-potable irrigation well at the Village Lakes HOA is located approximately 3,700 feet downgradient. Detailed well information about the CEMEX well and Village Lakes HOA well is not available. The City of Riverside’s Gage 46-1R well is included for reference; however, the current modeling shows that there is no impact to the Gage wells as the recharged water travels to the west approximately two miles north of these wells. As EVWD will need to take four wells out of service in the near term in order to initiate recycled water discharge to Weaver Basins, EVWD is completing a Groundwater Well Master Plan with GSSI to evaluate its near term and long- term options for use of existing groundwater wells and potential siting and construction of new groundwater wells. This plan will be completed in approximately summer 2022 and can be provided to DDW for review.

As described in Section 1.4, the objectives of the SNRC are to: • Treat and reuse wastewater for multiple beneficial uses within the upper Santa Ana River watershed to meet existing and future wastewater treatment needs within the EVWD service area. • Increase the use of recycled water to continue efforts toward resolving regional water supply challenges in a cost effective and environmentally responsible manner. • Increase groundwater replenishment opportunities in the Bunker Hill Subbasin with new local water resources. • Provide an administrative center that benefits the community in a manner that is compatible with neighboring land uses. • Increase local water supply operational flexibility within the San Bernardino Valley region to advance the integrated water management objectives of Valley District and the region. The evaluation of groundwater recharge impacts was conducted in light of these objectives. 10.1 Hydrogeological Analyses Overview GEOSCIENCE conducted a series of analyses of the Bunker Hill Groundwater Subbasin as a part of the evaluation of the identified discharge location alternatives. The analyses focused on the evaluation of discharge to Weaver Basins to evaluate compliance with Title 22 requirements for various recycled water recharge scenarios. 10.1.1 Groundwater Model Overview In order to predict compliance with recycled water regulatory requirements, an existing calibrated numerical groundwater model was used. The model selected was the Refined Basin Flow Model developed jointly by the City of San Bernardino Municipal Water Department and Valley District. This model is an integrated streamflow, groundwater flow, and solute transport model developed for the SBBA. Details of the model are provided in GEOSCIENCE 2019 and GEOSCIENCE 2021. The model was used to address key issues, including: • Predicted travel distance and seepage velocity of recycled water after 12 months, 10 years and 20 years of Project recharge • Model-predicted travel distance for recycled water after 15 months of project recharge to delineate the well control zone boundary. • Predicted retention time of recycled water • Predicted distribution of percent recycled water after 12 months, 10 years and 20 years of Project recharge • Predicted percentage of RWC at the nearest active municipal wells 10.2 Summary of Project Scenarios The Project is for a maximum 8.0 MGD treatment plant in its first phase (with buildout to 10 MGD at a later date). The technical memorandum summarizing the 8.0 MGD modeling for Weaver Basins was completed and stamped by hydrogeologists licensed in the state of California and is provided in Appendix A. The analyses show that the Weaver Basins has recharge capacities that allow full recharge of the projected future SNRC flow of 8.0 MGD. Chapter 10 East Valley Water District 10-5 Woodard & Curran Title 22 Engineering Report November 2021 10.3 SNRC Operational Strategy The Refined Basin Flow Model was used to evaluate the hydrogeological impacts of the proposed groundwater recharge of recycled water produced at the SNRC. The analysis assumed that a full 8.0 MGD would be conveyed to and released in Weaver Basins upon plant startup in 2022 through the end of the modeling timeframe in 2047. These modeling assumptions are conservative given that existing flow within EVWD’s sewer collection system is currently approximately 6.0 MGD. As such, the modeling results likely overestimate potential downstream impacts. However, given that downstream wells have been identified that could experience increases in TDS concentration due to elevated RWC in later years of the modeling timeframe, an adaptive management strategy is proposed for SNRC. Adaptive management is a recurring cycle of planning, management, and evaluation resulting in adaptation (Figure 10-1). Planning consists of defining the problem, objectives, the link between objectives and proposed actions and selecting actions; management consists of design and implementation of the actions selected; and evaluation involves analysis and synthesis of monitoring to evaluate the effectiveness of selected actions and inform adaptation. Adaptation can happen at any of the steps. Figure 10-1: Adaptive Management Cycle The SNRC adaptive management strategy will be used to ensure that recycled water contribution (RWC) in potable production wells downstream of the SNRC discharge to Weaver Basins does not exceed regulatory threshold of >20% over 120 month rolling average. This proposed adaptive management strategy provides a list of potential management actions that could be implemented to address anticipated impacts of the proposed discharge, depending on the outcome of the proposed groundwater monitoring program. The upper portion of Table 10-1 includes management actions that will be implemented from the beginning of SNRC implementation, while the lower portion of Table 10-1 indicates management actions that may be selected for implementation based on the outcomes of the Groundwater Monitoring Program (see Chapter 11).

Collaborate with San Bernardino Valley Municipal Water District (Valley District). To be evaluated in implementation plan. Chapter 10 East Valley Water District 10-7 Woodard & Curran Title 22 Engineering Report November 2021 Strategy Implementation Actions Timeline North Fork Diluent Planning and construction of pipeline extension from North Fork Channel crossing at Plunge Creek to Weaver Basins to provide diluent. Would reduce RWC in downgradient wells by replenishing Bunker Hill-B at Enhanced Recharge Basins nearby to Weaver Basins. Potential for 5mgd addition of North Fork water to recharge basins. Valley District may also be constructing a spreading basin to the east of Weaver Basins for stormwater recharge from Oak Creek and other sources where North Fork water could be added. To be evaluated in implementation plan. Enhanced Recharge Planning and construction of basin/facility to support enhanced stormwater/imported water recharge. Will be based on documentation of TDS and nitrogen quality of all sources of recharge and downgradient groundwater quality. EVWD and Valley District may also evaluate spreading recycled water and/or other local and imported water sources into additional recharge basins in the future to lower the RWC and TDS in the current project area. To be evaluated in implementation plan. Regional Desalter 4 Participate in planning and construction of regional desalter, potentially in collaboration with City of San Bernardino, Valley District, and/or other agencies. If installed on recycled water delivered to Weaver Basins would also lower TOC and allow for higher RWC. Would require rehab/repair of the SAR pipeline, brine line extension to proposed desalter location, and construction of desalter. To be evaluated in implementation plan.

Identify customers for non-potable water use. To be evaluated in implementation plan. 4 The Regional Desalter is included in Phase 2 of Valley District’s “Watershed Connect” Program. A handout for this program is included in Appendix G. Valley District is working with the EPA to secure WIFIA and other funding for Phases 1 and 2 of this program. Chapter 11 East Valley Water District 10-8 Woodard & Curran Title 22 Engineering Report November 2021 10.4 Retention Time and RWC - Weaver Basins (8.0 MGD) Retention time and RWC were modeled using the Refined Basin Flow Model and results summarized in the Sterling Natural Resource Center Project: Hydrogeological Analysis and Modeling Results for Scenario Weaver Basin (GSSI 2021) included as Appendix C. Table 10-2 provides a summary of the impacts to wells located downstream of the recharge areas in Weaver Basins. After some preliminary model runs, it was found that four active municipal wells (EVWD Plant No. 143, EVWD Plant No. 146, EVWD Plant No. 146A, and EVWD Plant No. 147) were too close to Weaver Basin (less than 2,000ft) to meet the CCR Title 22 Regulatory requirements. Therefore, these four wells were assumed to be inactive in final Scenario Weaver Basin model run and are not included in Table 10-2. Figure 10-2 provides a graphic representation of the modeled 12-month, 10-year, and 20-year travel times for the SNRC discharge. Results from the modeling indicate that the minimum retention time requirements are met at the proposed discharge location. Figure 10-3 provides a graphic representation of the RWC for the wells located down gradient from Weaver Basins. The shortest travel time downstream of Weaver Basins to an active well is 4.0 years modeled (2.0 years adjusted by 0.5) in the uppermost aquifer layer; however, EVWD has no active wells screened in the first aquifer layer. If screening is considered, then the shortest travel time is 7.2 years modeled (3.6 years adjusted by 0.5) at North Orange Well #1 in the fifth aquifer unit (LWB). The shortest time to reach 20% RWC is 6.0 years in the first aquifer layer in North Orange Well #1; however, this well is not screened in this aquifer layer. If screening is considered, all wells have greater than 15 years until 20% RWC is exceeded. 10.5 Antidegradation Analysis In November 2021, an Antidegradation Analysis: Sterling Natural Resource Center (EVWD, 2021) was prepared to support the RWQCB’s finding that the Project discharge maintains the existing high quality of water to the maximum extent possible. Discussions on assimilative capacity for TDS and nitrogen and the TDS and nitrogen quality in the basin post-recharge are discussed in that document.

All lab procedures will be performed by a state-certified laboratory in accordance with procedures under 40 CFR 136 “Guidelines Establishing Test Procedures for the Analysis of Pollutants,” promulgated by the U.S. EPA, unless otherwise specified by DDW or the RWQCB. The laboratory will be certified by the SWRCB Environmental Laboratory Accreditation Program (ELAP). In addition, the DDW, RWQCB and/or EPA may specify test methods which are more sensitive than those specified in 40 CFR 136. Laboratories are required to calibrate the analytical system down to the Reportable Detection Limits (RDLs) or minimum levels (MLs) as listed in the permit and summarized in the tables included in this section. An alternative RDL may be used if approved by the DDW and RWQCB. For priority pollutants without effluent limitations, the laboratory is required to quantify constituent concentrations to the lowest achievable reporting limit as determined by the testing procedure in 40 CFR 136. For unregulated chemical analyses and where practical, drinking water methods, or DDW-recommended methods, or EPA-approved methods if available, will be used. If those are unavailable, then the analyses will use methods available in published scientific literature or commercially available, after consultation with DDW. The laboratory will have in place quality assurance/quality control (QA/QC) procedures, including documentation of the chain of custody. QA/QC analyses will be run on the same dates as the actual sample analyses. Copies of the QA/QC reports will be retained on file and available for inspection when requested by DDW or the RWQCB. The reporting protocol calls for results greater than or equal to the ML to be reported as measured by the laboratory. Sample results less than the reported ML but greater than or equal to the laboratory’s Method Detection Limit (MDL) are reported as “Detected, but Not Quantified (DNQ)”. In that case, the estimated chemical concentration of the sample must also be reported. MDL is defined as the minimum concentration of a substance that can be measured and reported with 99 percent confidence that the concentration is greater than zero, as defined in 40 CFR 136. Sample results not detected above the laboratory’s MDL are reported as “non-detected (ND)”. Raw samples for bacterial analyses will be diluted as required to obtain meaningful results. Methods used for dilution will be reported with the results of the analyses. Depending on the constituent, sampling will be conducted on a continuous, 24-hour composite, or grab specimen taken at regularly scheduled intervals (daily, weekly, monthly, quarterly, semi-annual, or annually) as defined below: • A “grab” sample is defined as any individual sample collected in less than 15 minutes. • A “composite” sample is defined as a combination of no fewer than eight individual grab samples obtained over the specified sampling period. The volume of each individual grab sample should be proportional to the discharge flowrate at the time of sampling or, the number of equal volume samples should be proportional to the flow over the sampling period. The compositing period should be equal to the specific period, or 24 hours, if no period is specified in the permit. • Daily samples should be collected on each day of the week. Chapter 11 East Valley Water District 11-2 Woodard & Curran Title 22 Engineering Report November 2021 • Maximum daily concentration is defined as the measurement made on any single grab sample or composite sample. • Average weekly or monthly discharge limitations are determined from the average of the analytical results of all samples collected during a calendar week or month, respectively. Where a calendar week overlaps with two different months, compliance will be determined for the month in which the week ends. • 12-month average limits should be determined monthly by arithmetic mean of the last twelve-monthly averages. • Monthly samples should be collected on any representative day of each month. • Quarterly samples should be collected in January, April, July, and October. • Semi-annual samples should be collected in January and July. • Annual samples should be collected in accordance with the current Waste Discharge Requirements schedule for monitoring (RWQCB, 2012). 11.2 Influent Monitoring Influent sampling stations at the SNRC facility will be located upstream of any grit removal or treatment processes. The SNRC facility influent flow will be measured by a flow meter before any side streams or flow diversions in the treatment process are reached. These parameters will ensure the total influent flow and quality of raw wastewater can be determined. It is proposed the future influent monitoring requirements of WDR permit be used for the SNRC. Table 11-1 summarizes influent water flow and quality monitoring requirements from the RWQCB 2012 WDR permit for the SBWRP, where the wastewater for the SNRC currently is treated. Frequency of sampling is included in the table and is assumed to be similar to the future WDR permit for the SNRC. Chapter 11 East Valley Water District 11-3 Woodard & Curran Title 22 Engineering Report November 2021 Table 11-1: Current Influent Monitoring at the SBWRP Constituent Units Type of Sample Minimum Monitoring Frequency Flow MGD Recorder / Totalizer Continuous Specific Conductance µmhos/cm Recorder Continuous pH pH units Recorder Continuous Biochemical Oxygen Demand, 5-day (BOD5) mg/L Composite Daily COD mg/L Composite Daily Total Inorganic Nitrogen mg/L Composite Monthly Nitrate-Nitrogen mg/L Composite Monthly Total Dissolved Solids mg/L Composite Monthly Cyanide mg/L Grab Quarterly Total Suspended Solids mg/L Composite Weekly Volatile Organic Portion of USEPA Priority Pollutants µg/L Grab Annually Remaining USEPA Priority Pollutants µg/L Composite Annually 11.3 MBR System Monitoring Title 22 requires that the turbidity of the filtered wastewater does not exceed (1) 0.2 NTU more than 5 percent of the time within a 24-hour period and (2) 0.5 NTU at any time (Title 22 §60301.320). Turbidity of the filtered wastewater will be monitored from the combined ultrafiltration MBR effluent, prior to the UV disinfection system. In addition to the Title 22 requirements, in order to receive virus credit via the Australian Tier 1 MBR validation protocol, the MBR effluent must meet these turbidity requirements and divert whenever effluent turbidity is greater than 0.5 NTU (WRF, 2021). 11.4 UV Disinfection System Monitoring The high operating temperature of UV lamps demands that a water flow be maintained through the reactor chamber to cool the lamps. If the water flow is shut off for any reason, the lamps must be shut off to prevent overheating. The temperature switch will trigger a warning alarm and shut down the system if the wall temperature of the reactor chamber exceeds 120 degrees F (50 degrees C). This alarm will be displayed on the operator interface. UV Sensor/Monitors measure the UV intensity within the reactor. This compact circuit contains all the necessary electronics to convert the input UV signal into a 4-20mA instrumentation signal. This signal is continuously displayed on the operator interface in mW/cm2. The UV intensity sensor alarm will be preset at the factory at a 25% reduction of lamp output. 11.4.1 Procedure Used to Derive Operation UV Dose Source water is pumped into the UV channel. Prior to entry into the channel, UV absorbers and challenge organisms are injected into the influent stream, passed through a static mixer to ensure complete mixing. A calibrated flow meter upstream of the channel is used to verify influent flow. Only one channel will be tested at a time. A sample is collected from the UV channel effluent. Water containing a microbial surrogate is subjected to UV disinfection under a variety of conditions (flow, UVT, Power, number of banks). Both influent and effluent samples are taken for microbial enumeration. The log inactivation is determined under each condition and a model developed. In addition to ensuring the appropriate test conditions, equipment configuration, instrument calibration, it is important to confirm the actual Chapter 11 East Valley Water District 11-4 Woodard & Curran Title 22 Engineering Report November 2021 functionality of the equipment. Key parameters to measure include: channel water depth, lamp output variability, UV intensity output, power consumption, UV sensor variability, and head-loss. 11.4.2 Lamp Control and Monitoring Each UV bank will respond to a 4-bit power level signal, which will instruct the lamp ballast to adjust to the correct power level as determined by the PLC. Each lamp is controlled directly from the lamp ballast, which is fully modulated between minimum and maximum power levels for each reactor. Specifically designed current sensing circuits detect lamp on/off status. The status of each individual lamp is displayed via the Train Control screen at the Operator Interface. Faulted lamps are indicated graphically on the Train control screen. A local display of lamp status is also provided on each operator interface. 11.4.3 Automatic Cleaning System (Wiper) Control and Monitoring During a wipe sequence, the lamps in the bank will be wiped in a staggered sequence (i.e., only one bank is in wiping mode at one time). A wipe sequence to clean each lamp may be initiated either manually at the PLC or operator interface, or automatically as scheduled by the controller. In Automatic mode, the interval between wiping sequences is determined by the “wiper sequence” timer, which is pre-set at 24 hours and adjustable from 1 to 800 hours. 11.5 Recycled Water Monitoring Recycled water sampling stations will be located at the SNRC facility, after the point of UV disinfection. Here representative samples of the tertiary treated effluent can be obtained before it is distributed to the appropriate spreading basin. Recycled water quality will be monitored at this location as well as flow to continuously measure and record/totalize the amount of recycled water pumped to the spreading basins. The flow rates and total volumes of recycled water will be continuously measured and recorded for compliance with the RWC limit. Flow measurement devices will be calibrated per manufacturer’s recommendations at least once per year to ensure continued accuracy. Table 11-2 summarizes the monitoring program for recycled water. Further discussion of specific constituents follows.

The complete list of constituents to be monitored will be identified by the RWQCB as part of the Waste Discharge Requirements. 3. The complete list is identified in the Recycled Water Policy. 11.5.1 TOC and TN Compliance Monitoring TOC is used as a surrogate for treatment performance, organics removal, CEC removal, and soil aquifer treatment performance. The maximum TOC concentration, measured in milligrams per liter (mg/L), is established by the following equation (Section 60320.118): TOCmax = 0.5 mg/L ÷ RWC Where: RWC is the running monthly average recycled water contribution Compliance with the maximum TOC concentration is based on the 20-week running average of all TOC results and the average of the last four TOC results. TOC monitoring will be conducted at the location of undiluted recycled water discharged from the plant. Total Nitrogen (TN) is the sum of nitrate, nitrite, ammonia, and organic nitrogen, all expressed as nitrogen (N). Monitoring for TN will be conducted twice a week, at least three days apart. Monitoring for TOC and TN will be conducted as described in Table 11-2 above. Chapter 11 East Valley Water District 11-6 Woodard & Curran Title 22 Engineering Report November 2021 11.5.2 Regulated Contaminants Monitoring Monitoring will be conducted for: • Inorganics with primary drinking water MCLs (including nitrogen compounds) listed in Table 11-3; • Radionuclides with primary MCLs listed in Table 11-4; • Regulated organics with primary MCLs listed in Table 11-5; • Disinfection byproducts listed in Table 11-6; and • Constituents and parameters with secondary drinking water MCLs listed in Table 11-7.

It also instructs all RWQCBs to not issue requirements for monitoring of additional CECs in recycled water beyond the requirements provided in the Recycled Water Policy, except when recommended by DDW or requested by the project sponsor. The SNRC Project at proposed surface application locations will comply with the SWRCB’s amended Recycled Water Policy (SWRCB, 2018). The amended Recycled Water Policy provides for development of a CEC monitoring program for a recycled water groundwater recharge project by completing three phases: 1. Initial monitoring phase 2. Baseline monitoring phase 3. Standard operation phase The Recycled Water Policy requires that an initial assessment monitoring phase be conducted to assess the occurrence of health-based CECs, performance-indicator CECs, and surrogates in recycled water and groundwater recharged via surface spreading. This initial phase requires quarterly monitoring of health-based and performance- indicator CECs, plus monitoring of surrogates on a project-by-project basis. Recycled water quality monitoring must be conducted prior to discharge at the spreading basin(s) for surface applications. Groundwater monitoring at a monitoring well located within 30-days downgradient from the spreading basin(s) is required for health-based CECs, performance indicated CECs and surrogates for that specific project. Based on the findings of the initial assessment monitoring phase, the RWQCB with input from DDW selects project specific-performance indicator CECs and surrogates for monitoring during the subsequent baseline monitoring phase. The monitoring phase requirements are similar to those for the initial phase, except that the sampling frequency is reduced to semi-annually. Health-based CECs continue to be monitored, but only selected performance-indicator Chapter 11 East Valley Water District 11-12 Woodard & Curran Title 22 Engineering Report November 2021 CECs and surrogates must be monitored to establish a project-specific baseline (For more information about the baseline monitoring requirements, see Table 4 of the Recycled Water Policy.) The findings of the baseline monitoring phase are used to establish the standard operation monitoring program for the project. As above, the RWQCB with DDW refine and select the project-specific requirements for monitoring CECs and surrogates in the standard operation monitoring program for the project. The Recycled Water Policy requires semi- annual monitoring for health-based CECs and selected performance-indicator CECs, treatment process performance, and recycled water quality, and in that case, annual monitoring may be allowed. (For more information about standard operation monitoring program requirements, see Table 5 of the Recycled Water Policy.) EVWD will also comply with the requirement to evaluate bioanalytical assay monitoring results (Section 5.3 of the Recycled Water Policy). EVWD is required to collect samples from the groundwater monitoring wells downstream of the recharge project using the Estrogen receptor-α and Aryl hydrocarbon receptor (AhR) screening tools. There is currently a WateReuse and SWRCB workgroup on bioanalytical tools and EVWD will comply with the outcome of the workgroup’s recommendations for implementation. 11.5.5 SAT Performance Monitoring SAT may be used to lower the TOC and TN concentrations. Composite samples of percolated water, either undiluted recycled water or diluted recycled water, in the unsaturated zone will be taken for analyses if TOC and TN reductions through SAT is needed. Demonstration studies will be conducted to determine the removal efficiency of the SAT, which will be used to develop an SAT factor for review by DDW. The approved SAT factor will then be applied to the measured undiluted recycled water TOC, thereby yielding the post-SAT TOC and TN values. SAT monitoring will also be conducted for three indicator compounds designated by DDW based on results of studies of the recycled water. 11.6 Recycled Water Contribution Monitoring Flows of recycled water will be continuously metered and used to calculate the RWC. Daily flows will be recorded and used to determine the monthly volumes of recycled water applied at the Weaver Basins application location. The diluent water from groundwater underflow has been modeled as discussed in Chapter 7:. Groundwater levels are monitored annually by others and will be used to determine if the underflow volume in the calculation should be decreased or increased based on the water level that year. Compliance with the RWC will be calculated monthly as the running monthly average RWC based on the total volumes of recycled water and credited diluent water during the preceding 120 months. The RWC calculation will begin after 30 months of spreading and be based on the initial preceding 30 months’ volumes of recycled water and credited diluent, gradually increasing to the allowable 120-month period. 11.7 Diluent Water Quality Monitoring For the proposed GRRP project, diluent water will consist solely of groundwater underflow. Since no other sources of water will be used to supplement the recycled water in surface application, refer to Section 11.8 for the two proposed upstream monitoring wells which will be used to gauge diluent water quality. 11.8 Groundwater Monitoring Wells Groundwater monitoring will be used in the continuous assessment of groundwater quality and to determine any impacts from the recharge of recycled water. A finalized groundwater monitoring program will be developed in conjunction with the DDW and the RWQCB. Both agencies may specify any contaminants and chemicals be monitored based on the results of the recycled municipal wastewater monitoring conducted. Until such time, a preliminary draft of groundwater monitoring requirements is presented in Table 11-10. Chapter 11 East Valley Water District 11-13 Woodard & Curran Title 22 Engineering Report November 2021 Table 11-10: Proposed Groundwater Monitoring Well Sampling Requirements Constituent Category 1 Monitoring Frequency Nitrate and Nitrite Quarterly Constituents with Secondary Drinking Water MCLs Quarterly Total Nitrogen Quarterly Total Organic Carbon Quarterly Note: 1. MCLs = maximum contaminant levels. Should any of the groundwater monitoring results exceed the MCL for a specific contaminant, a second sample shall be analyzed for the contaminant within 48 hours of being notified by the laboratory. If the second sample exceeds MCL, within 24 hours of being notified by the laboratory, the district will notify the DDW and RWQCB and the district shall discontinue surface application of recycled water. Continued surface application of recycled will begin once corrective actions have been taken or evidence is provided to the DDW and RWQCB that the contamination was not a result of the GRRP. Table 11-11 provides a summary of the proposed monitoring wells discussed in further detail below. Table 11-11: Summary of Proposed Monitoring Wells for Weaver Basins Well Owner Distance Travel Time Sampling Frequency EVWD Plant No. 120 EVWD 3,300 ft up gradient of Weaver Basins N/A Quarterly MW-A Proposed 600 ft down gradient of Weaver Basins Between 15 and 30 days down gradient of Weaver Basins Quarterly MW-B Proposed 3,500 ft down gradient of Weaver Basins 180 days upgradient of nearest production wells (N. Orange #1 and #2) Quarterly MW-C Proposed 11,800 ft down gradient of Weaver Basins 180 days upgradient of nearest active EVWD production wells (EVWD Plant No. 141 and 151) Quarterly Figure 11-1 provides an overview of the monitoring well locations. MW-A and MW-B will be operational by the start of recycled water recharge at Weaver Basins. The third, MW-C, will be installed within 10 years of the start of operation to characterize recycled water contribution and the diluent effect from City Creek. The proposed monitoring network is to monitor and evaluate water quality impacts of recycled water recharged at spreading basins on the groundwater subbasin, and to ensure compliance with minimum retention times for recycled water. According to the Title 22 Monitoring Well Requirements (§60320.126) for surface spreading, at least two downgradient monitoring wells shall be constructed and located between the spreading basin discharge facility and the nearest down gradient municipal wells. One of these wells is required to be situated no less than two weeks but no more than six months of travel time through the saturated zone affected by the recharged water. This location is represented by MW- A, which will be co-located with EVWD 143. The other shall be located at least 30 days upgradient of the nearest drinking water well. This location is represented by MW-B, which will be located approximately 180 days upgradient of N. Orange Well #1. Figure 11-2 provides anticipated area of the 5% RWC contour after the first year of recharge operation, relative to the monitoring well locations. Figure 11-3 shows the conceptual construction details of the proposed monitoring wells.

Each sample will be analyzed for total nitrogen, nitrate, nitrite, the contaminants in Tables 64449-A and B or §64449 and any contaminants and chemicals specified by DDW or the Santa Ana RWQCB based on the results of the recycled municipal wastewater monitoring conducted pursuant to Title 22 §60320.126. 11.8.2 Standard Operation Groundwater Monitoring Following the commencement of GRRP operation at least one sample per quarter will be analyzed from each monitoring well that has recharge water located within one year of travel time of the well(s). Each sample will be analyzed for total nitrogen, nitrate, nitrite, the contaminants in Tables 64449-A and B or §64449 and any contaminants and chemicals specified by DDW or the Santa Ana RWQCB based on the results of the recycled municipal wastewater monitoring conducted pursuant to Title 22 §60320.126. In addition, the groundwater shall be tested quarterly for specified priority toxic pollutants listed in 40 CFR section 131.38 of “Establishment of numeric criteria for priority toxic pollutants for the State of California” and other chemicals that the DDW has deemed necessary based on the GRRP’s engineering report, affected groundwater basin, and the results of the assessment performed pursuant to Title 22 §60320.106. 11.8.3 Groundwater Monitoring Summary As mandated by Title 22, groundwater monitoring will occur at least once per quarter, for all required constituents and report all required information. 11.9 Well Control Zone Per Title 22 (§60320.100(e)(2) and 60320.100(e)(3)), no new drinking water wells may be developed within the primary (14 months travel time) surrounding the Weaver Basins recharge site. Figure 11-4Figure 11-4 provides the well control zones for the SNRC. This well control zone is based on the time of travel to meet the pathogen inactivation requirements underground and will be revised after the tracer study is completed. The 20% RWC maximum is not met at the primary well control zone boundary of 15 months for Weaver Basins. [EVWD Plant No. 143, 147, 146, and 146A are municipal supply wells within the well control zone for Weaver Basins; however, these wells will be inactivated before recharge begins at Weaver Basins.] Therefore, the well control zone has been proposed to be expanded from the Weaver Basin recharge site to the 210 Freeway, at which point, the recharged water picks up additional groundwater underflow for diluent from water recharged into Weaver Basins. Typically, a secondary well boundary is shown at approximately 1.5 times the primary zone boundary and any well drilled within this boundary needs to be reviewed to ensure that its pumping operations do not result in a time of travel of less than the time required to meet the pathogen requirements in the new well or existing wells downgradient of the new well. However, due to the expanded well control zone, a secondary well boundary was not determined as the expanded zone should ensure that the pathogen requirements are always met. As set forth in the Judgment in Case No. 78426, Valley District, in coordination with Western Municipal Water District of Riverside County, serves as the Watermaster for the Bunker Hill Groundwater Subbasin. In this court adjudicated role, Valley District has full control over the location and volume of pumping in the Bunker Hill Groundwater Subbasin. As the Watermaster, Valley District will not allow pumping in the Well Control Zone, thus ensuring adequate response retention time of at least 7.5 months (15 months as estimated by numerical groundwater modeling). To ensure that no new drinking water wells are drilled in the well control zones, the following steps will be taken by the project partners: • Because the proposed recycled water recharge overlies the Valley District service area, and Valley District serves as the Watermaster for the Bunker Hill Groundwater Subbasin, Valley District will not allow any new well drilling activity within the Well Control Zone. Chapter 11 East Valley Water District 11-18 Woodard & Curran Title 22 Engineering Report November 2021 • The proposed recharge overlies the EVWD service area, who will notify Valley District of any well drilling activity in the vicinity. • Valley District will coordinate directly with the County Department of Public Health and develop a memorandum of understanding to ensure that Valley District is notified of any new well drilling activity. 11.10 Village Lakes HOA Well and CEMEX Well As shown in Figure 11-4, the Village Lakes HOA well is located at the edge of the well control zone to meet pathogen requirements, at approximately 3,700 feet downgradient of Weaver Basins. As the well is in the expanded well control zone and as the RWC that exceeds 20% at this location, the well will be considered non-potable. The HOA uses the well solely for filling the three on-site impoundments. The annual water usage is approximately 53 AFY or 0.05 MGD on average. The depth of the well and screening is unknown. Requirements similar to those includes in Chapter 13 are anticipated to be required. However, barriers around the lakes are not required as the water provided is disinfected tertiary quality or better. EVWD will work with Village Lakes HOA to have this site classified as a “non-potable” use site with the San Bernardino District DDW office. This is anticipated to include development of site drawings, completing a cross connection test, designation of a site supervisor by the HOA and inclusion in EVWD’s monitoring and reporting program for “recycled water use” at this site. As shown in Figure 11-4, “CEMEX Well-01” is located downgradient of the well control zone and is located approximately three years (modeled time of travel) or 12,000 feet downgradient of Weaver Basins. The depth of the well and screening is unknown. This site is regulated by the San Bernardino District County DPH as a public water system due to the presence of two restrooms on site. The well water is primarily used for ready mix of concrete and for truck washdown. CEMEX provides bottled water to staff. However, the presence of the two restrooms qualifies the site as a public water system as water provided for hand washing must meet the Safe Drinking Water Act. This location is located outside of EVWD’s service area; however, EVWD has the closest water line to the site. EVWD is working with CEMEX to provide potable water service to the site, such as by an extension of service, or a mutually agreed upon alternative. The well would remain in service to provide non-potable water only and after the RWC exceeds 20% (in approximately 3.5 years modeled travel time), EVWD would work with the San Bernardino District DDW office to also classify this as a “non-potable” use site. Chapter 11 East Valley Water District 11-19 Woodard & Curran Title 22 Engineering Report November 2021 Figure 11-4: 15-Month and Expanded Well Control Zones for Weaver Basins Chapter 10 East Valley Water District 11-20 Woodard & Curran Title 22 Engineering Report November 2021 11.11 Reports and Records In accordance with all requirements, EVWD will provide reports and records of past, current and projected operational information. 11.11.1 Monitoring Reports The following monitoring records will be retained for a time as directed by DDW and the RWQCB: • Sampling location, date, and time; • Name(s) of individual(s) performing the sampling; • Analytical results; • Analytical methods/techniques used; • Date of the analyses; • Name of laboratory conducting the analyses with its ELAP certification documentation; and • Documentation of quality assurance/quality control, including chain of custody 11.11.2 Annual Report As required by Title 22, EVWD will submit a report at the end of each calendar year. The report will be provided to the DDW and RWQCB within six months after the end of each calendar year. Public water systems and drinking water well owners with water sources within 10 years of groundwater travel time downgradient of Weaver Basins will be notified by mail of the availability of the report. The report will be prepared by a licensed California engineer with experience in wastewater treatment and public water supply. The report will include the following topics: • Compliance status with monitoring requirements • Violations incurred and corrective actions • Detections and trends of monitored chemicals or contaminants • Migration of the recharge water plume • Description of changes and anticipated changes in processes or facilities • Projected quality and quantity of recycled water and diluent water • Measures taken to comply with specific Title 22 requirements • Increases and projected increases in the recycled water contribution 11.11.3 Engineering Report Update In accordance with Title 22, an updated engineering report will be provided to the DDW and RWQCB every five years from the date of approval of the initial engineering report. The engineering report update will serve to address any project changes. At a minimum, the report will include the following: • Anticipated recycled water contribution increases • Information showing retention time compliance • Groundwater modelling updates and measured observations. Chapter 12 East Valley Water District 12-1 Woodard & Curran Title 22 Engineering Report November 2021 CHAPTER 12: OPERATING AND CONTINGENCY PLANS As the SNRC completes the design phase, an operating and contingency plan will be developed for the Project which will include the following: • Power Failure Safeguards and Safety Plan: The SNRC will be equipped with an automatic generator for the purposed of treating wastewater during power outages. If the emergency generator were to fail, flows would not be diverted from the sewer at the influent pump stations. • Standard Operating Procedures (SOPs): A full suite of SOPs will be developed for the operation of the various treatment process at SNRC, the discharge structures at each recharge location, and the overall operations strategy for treatment and recharge. • Contingency Plan: Procedures will be to be put in place to assure that no untreated or inadequately treated wastewater will be delivered to the use area. • Emergency Response Plan: Procedures will be put in place to assure that any discharge of untreated or partially treated wastewater to the use area will be reported immediately by telephone to the regulatory agency, the State Department of Health, and the local health officer. • Recycled Water Training: Training on the safe use of recycled water will be provided to all employees involved in the productions and recharge of recycled water. As stated previously, the Project will be implemented under a design-build procurement. The above items will be included as part of the required Operation Optimization Plan under the GRRP Regulations. Chapter 13 East Valley Water District 13-1 Woodard & Curran Title 22 Engineering Report November 2021 CHAPTER 13: NON-POTABLE REUSE SITE EVWD is planning to provide recycled water to one non-potable reuse site, the landscape ponds at the Administrative Center across the street from the SNRC, as shown below in Figure 13-1. These ponds are on EVWD’s property and distribution and use of recycled water in the ponds will be the responsibility of EVWD. The ponds will be filled primarily with disinfected tertiary recycled water. However, if SNRC effluent meets disinfected secondary 23 quality but not disinfected tertiary quality, the setbacks and restrictions as discussed below meet the requirements for a disinfected secondary 23 landscape impoundment. A potable water makeup line will also be included and an air gap that meets the requirements of Title 17 will be used. The ponds are restricted and include guard rails around the perimeter of the ponds to prevent public access. Signage will be included indicating that the ponds are filled with recycled water and that fishing, boating, swimming and other public access is not allowed. To maintain water quality, the water in the ponds is recirculated. The ponds flow from east to west and the inlet to the east pond cascades over a series of rocks prior to entering the pond. There is aeration in the pond, but a decorative fountain is not included and there is no spray or mist that occurs during operation of the aeration system. There are no wells within 1000 feet of the landscape ponds and thus section 60310(b) and (c) are met, allowing the ponds to be filled with either disinfected secondary 23 or disinfected tertiary 2.2. The ponds will be maintained with at least two feet of freeboard to prevent overflow. Detailed piping plans, site drainage plans, and a cross connection shut down test plan will be provided to the San Bernardino DDW District office for review and approval prior to initiating discharge to the ponds. EVWD will observe the use site at least landscape ponds at least quarterly for freeboard, odors, drainage/runoff, ponding, and notification signs and report the results at least annually to the RWQCB.

BROWN JR. Director Governor August 24, 2012 Mark Eyre Market Regulatory Manager Trojan Technologies 3020 Gore Road London, Ontario, Canada N5V 4T7 Dear Mr. Eyre, CONDITIONAL ACCEPTANCE OF TROJANUVFITTM MODEL 72AL75 UV FOR RECYCLED WATER, VALIDATION REPORT, November 2009 The California Department of Public Health (CDPH) Drinking Water Program’s Recycled Water Committee (RWC) has reviewed the submittal entitled “Trojan Technologies, TrojanUVFitTM 72AL75 Validation Report” (Carollo Engineers, November 2009)1 which contains the bioassay results. The TrojanUVFitTM Model 72AL75 UV reactor UV disinfection system was tested and the results analyzed in accordance with the August 2012 Ultraviolet Disinfection Guidelines for Drinking Water and Water Reuse published by the National Water Research Institute/AWWA Research Fou ndation (NWRI). This reactor is a closed vessel UV system utilizing low-pressure high-output (LPHO) lamps (Heraeus Noblelight, Trojan part number 794447). The ballasts are adjustable from 60 to 100 percent of full power. Model 72AL75 has 72 lamps. The lamps are mounted horizontally and parallel to the flow, within a 30-inch diameter closed vessel reactor. Integral to the performance monitoring of the system is a calibrated germicidal sensor that meets international standards (DVGW ) or the USEPA UV Disinfection Guidance Manual (UVDGM), where the sensor is calibrated against a traceable standard. The reduction equivalent dose (RED) for the TrojanUVFitTM Model 72AL75 UV reactor is a function of flow rate (Q), UVT, and normalized UV sensor value (S/S0) or relative lamp output. Detailed testing was performed to determine the flow-specific performance of the TrojanUVFitTM Model 72AL75 UV reactor for flow rates ranging from 0.73 to 7.39 MGD (500 to 5,128 gpm) per reactor, at UVTs ranging from 55 to 81.0 percent, and sensor intensities ranging from 0.21 to 2.03 mW/cm2. 1 Agencies interested in this technology can obtain copies of the September 2009 Carollo Engineers report from Mark Eyre, Trojan Technologies, 3020 Gore Road, London, Ontario, Canada N5V 4T7. Division of Drinking Water and Environmental Management 1350 Front Street, Room 2050, San Diego, CA 92101 (619) 525-4497 (619) 525-4383 Fax Internet Address: www.cdph.ca.gov Mark Eyre, Trojan Technologies August 24, 2012 Page 2 of 4 The validation report test data has been analyzed and evaluated in detail in light of the 2012 NWRI Ultraviolet Disinfection Guidelines. The RW C finds that the validation testing and report have demonstrated the ability of the TrojanUVFitTM Model 72AL75 UV reactor UV Disinfection System to meet the minimum coliform and virus disinfection criteria found in Title 22 of the California Code of Regulations (CCR) for recycled waters that have received treatment through an tertiary filtration process accepted by CDPH. The acceptance of the validation report is condition al based on the following criteria, which must be met and/or demonstrated: 1. The TrojanUVFitTM Model 72AL75 UV Disinfection System must be preceded by filtration meeting the definition of "filtered wastewater" under CCR, Title 22, Section 60301.320. 2. Conditional acceptance for the TrojanUVFitTM Model 72AL75 UV reactor is limited to the following parameter ranges: a. flow rates ranging from 0.73 to 7.39 MGD (500 to 5,128 gpm) per reactor b. UVTs at or above 55 percent, c. UV sensor intensities ranging from 0.21 to 2.03 mW/cm2. 3. In light of the 2012 NWRI, the following two empirical equations, based on a detailed analysis of the performance data collected during the validation test, must be used for calculation of the RED value in actual installations. These equations are to be used as part of the automatic UV disinfection control system for calculating UV dose and should be specified as a permit provision. S0 = 1.0536 X 10 −5 x UVT 2.7691 REDcalc = 0.90 x 10 -1.0582 x Q -0.7658 x UVT 1.8052 x [S/So] 0.7590 Where: UVTs at or above 55 percent 2, S = Measured UV sensor value (mW/cm2). So = UV intensity at 100 percent lamp power (new lamps) with clean sleeves, typically expressed as a function of UVT (mW/cm2). RED = RED calculated with the UV dose-monitoring equation (mJ/cm2). Q = Flow rate, in million gallons per day in one reactor 3, 2 At UVT values above 81.0 percent, the value (81.0 percent UVT) should be used as the default value in the RED calculation. 3 At flow rates below 0.73 MGD, this value (0.73 MGD) should be used as the default value in the RED calculation.. Mark Eyre, Trojan Technologies August 24, 2012 Page 3 of 4 4. To verify performance on the site-specific recycled water, upon completion of construction and prior to operation, an on-site check-point bioassay must be performed on the reactor using seeded MS2 coliphage in a method similar to that demonstrated in the 2009 report from Carollo Engineers. The on-site bioassay protocol must be approved by CDPH and must be conducted over a range of flows. Results, documenting virus disinfection performance of the system to the standards found in Title 22 of the California Code of Regulations, must be submitted to the CDPH for approval. 5. Conditional acceptance is predicated upon using a calibrated germicidal sensor that is integral to the performance monitoring of the system, and which meets international standards (DVGW) or the USEPA UV Disinfection Guidance Man ual (UVDGM), where the sensor is calibrated against a traceable standard . 6. The TrojanUVFitTM Model 72AL75 UV reactor uses UV lamps by Heraeus Noblelight (Trojan part number 794447). This validation report does not address the determination of lamp aging or lamp fouling factors. Instead, this validation is based upon dose-pacing methodology, relying on detailed and accurate UV sensor readings to confirm adequate UV dose delivery similar to drinking water UV applications, so that the regulated UV dose is d elivered and the combined effects of lamp aging and sleeve fouling are incorporated.4 Detailed information related to the UV sensors to be employed under this project is presented in the 2009 report from Carollo Engineers. 7. The accuracy and repeatability of the on-line UV sensors must be demonstrated to the CDPH. The site specific engineering report must specify the frequency that calibration checks should be performed. 8. The validation report did not address sleeve fouling. Each site should address the fouling potential of the wastewater. Each site must demonstrate proper cleaning procedures are in place. Proper maintenance and cleaning must be performed. The dose equation does not incorporate a fouling factor. This is not essential due to the fact that this reactor is proposed to be controlled via a calibrated germicidal sensor, which will account for the amount of lamp fouling in its intensity readings. However, the design engineer must consider fouling in the overall design capacity calculations. 9. On-line monitoring of flow, UVT, and intensity must be provided at all times. 4 Since the UV Intensity sensor monitors more than one lamp, the lamps should be rotated once a quarter to ensure uniform intensity due to aging. Unless another operational procedure can be developed and demonstrated, the rotation of lamps described in the EPA UVDGM should be followed quarterly, “If UV sensors monitor more than one lamp, verify that the lamp with the lowest intensity value is closest to the UV sensor by replacing the lamp closest to the UV sensor with one-fourth of the lamps in each row/bank (minimum of three). Place the lowest intensity lamp next to UV sensor.” “If all the lamps monitored by a UV sensor are close in age (i.e., their age varies by less than 20 percent), it is not necessary to check the output of each lamp. In this case, the oldest lamp should be placed in the position nearest the UV sensor.” Mark Eyre, Trojan Technologies August 24, 2012 Page 4 of 4 10. The TrojanUVFitTM Model 72AL75 UV reactor UV system must be designed with a built-in automatic reliability feature that must be triggered when the system is below the target UV dose. If the measured UV intensity goes below the minimum UV Intensity, the UV system must alarm and start the next available reactor. Further conditions that should shut a reactor down include: intensity monitor failure, reactor failure, multiple lamp failure, and ballast high temperature. Review and acceptance of individual systems will be handled on a case -by-case basis by the CDPH’s individual District offices.

The Carollo report presents the results of the bioassays analyzed per the August 2012 National Water Research Institute (NWRI)/Water Research Foundation Ultraviolet Disinfection Guidelines for Drinking Water and Water Reuse (hereinafter referred to as 2012 NWRI Guidelines). The TrojanUVSigna™ (2-Row) is an open channel system that consists of 1,000 watt low-pressure, high-output (LPHO) amalgam lamps oriented at a 45-degree angle to the direction of flow. The test system was comprised of four banks in series with each bank having eight Trojan Lamps with two staggered rows of 4 lamps, for a total of 32 lamps. The TrojanUVSigna UV disinfection system utilizes 1000-W Trojan Solo Lamps (Trojan part number 908069-200) manufactured by Philips. Integral to the performance monitoring of the UV system is a calibrated germicidal sensor that meets the National Institute of Standards and Technology (NIST) traceable standard. The operating approach uses a “dose-pacing” methodology, relying on detailed and accurate UV sensor readings. The reduction equivalent dose (RED) for the TrojanUVSignaTM UV reactor is a function of flow rate (Q), UV transmittance (UVT), and normalized UV sensor value (S/S0). Detailed testing was performed to determine the flow-specific performance of the TrojanUVSignaTM UV reactor for flow rates ranging from 99.4 to 1,211 gpm/lamp, at UVTs from 53.7% to 80% (0.27 to 0.097 UVA), and sensor intensities ranging from 1.11 to 10.46 mW/cm2. The DDW RWU finds that the validation testing and report have demonstrated the ability of the TrojanUVSignaTM UV reactor to meet the minimum coliform and virus disinfection criteria found in Title 22 of the California Code of Regulations (CCR) for recycled waters that have received treatment through an tertiary filtration process accepted by DDW. The acceptance of the validation report is conditioned on the following criteria, which must be met and/or demonstrated: 1. The TrojanUVSignaTM Disinfection System must be preceded by filtration meeting the definition of "filtered wastewater" under CCR, Title 22, Section 60301.320. Steve McDermid, TrojanUVSigna - 2 - March 17, 2017 2. Conditional acceptance is limited to the following parameter ranges: a. from 99.4 to 1,211 gpm/lamp b. UVTs at or above 53.7 percent, c. UV sensor intensities ranging from 1.11 to 10.46 mW/cm2, d. Power range 30 to 100 percent. 3. The equations below must be used for calculation of the UV dose value in actual installations. These equations are to be used as part of the automatic UV disinfection control system for calculating UV dose for the reactor and should be specified as a permit provision. They are: S pred = 10-4.16162 ×UVT1.91459 × BPL0.76858 REDcalc = CR x 10[4.58043-1.65778 x UVA] x UVA 254[ 2.54274 x UVA] x [S/So]0. 97312 x Q -0 97312 x B Where: BPL = Ballast power level setting (percent) UVT = UV transmittance through 1 cm of water at 254 nm, expressed as percent, at or above 53.7 percent1, Spred = Predicted UV sensor value (milliwatts per square centimeter [mW/cm2]) S = Measured UV sensor value (mW/cm2) So = Calculated intensity from new lamp at full power (at same UVT) with clean sleeves, typically expressed as a function of UVT (mW/cm2). REDcalc = UV dose calculated with the UV dose-monitoring equation (mJ/cm2) CR = Confidence factor = 0.884 A254 = UV absorbance at 254 nm (cm-1). Q = Flow rate per lamp, calculated as gpm divided by the number of lamps in one bank (gpm/lamp) B = Number of operating banks. 4. To verify performance on the site-specific recycled water, upon completion of construction and prior to operation, an on-site check-point bioassay must be performed on the reactor using seeded MS2 coliphage as described in August 2012 NWRI Guidelines. The on-site bioassay protocol must be approved by the DDW and must be conducted over a range of flows. Results, documenting virus disinfection performance of the system to the standards found in Title 22 of the California Code of Regulations, must be submitted to the DDW for approval. 5. Conditional acceptance is predicated upon using a calibrated germicidal sensor that is integral to the performance monitoring of the system, and which meets the National Institute of Standards and Technology (NIST) traceable standard. 6. The TrojanUVSignaTM UV reactor uses Trojan Solo Lamps made by Philips (Trojan part number 908069-200). This validation report does not address the determination of lamp aging or lamp fouling factors. Instead, this validation is based upon dose-pacing methodology, relying on detailed and accurate UV sensor readings to confirm adequate UV dose delivery similar to drinking water UV applications, so that the regulated UV dose is 1 At UVT values above 80 percent, the value (80 percent UVT, or A 254 =0.097) should be used as the default value in the RED calculation. Steve McDermid, TrojanUVSigna - 3 - March 17, 2017 delivered and the combined effects of lamp aging and sleeve fouling are incorporated2. Detailed information related to the UV sensors to be employed under this project is presented in the 2016 report from Carollo Engineers. 7. The accuracy and repeatability of the on-line UV sensors must be demonstrated to the DDW. 8. On-line monitoring of flow, UV intensity, UVT, UV lamp operation hours, and power must be provided at all times. 9. The flow meters, UV intensity sensors, and UVT analyzers must be calibrated in accordance with procedures and frequencies recommended by the manufacturers to ensure proper disinfection. 10. At least monthly, all duty UV intensity sensors must be checked for calibration against a reference UV intensity sensor. 11. For all UV intensity sensors in use, the ratio of the duty UV sensor intensity to the reference UV sensor intensity must be less than or equal to 1.2. If the calibration ratio is >1.2, the failed duty UV sensor must be replaced by a properly calibrated sensor and recalibrated by a qualified facility. The reference UV intensity sensors shall be recalibrated at least annually by a qualified facility using a National Institute of Standards and Technology (NIST) traceable standard. 12. The duty online UVT analyzer must be inspected and checked against a reference bench- top unit to document accuracy on a weekly basis. 13. The on-line UVT analyzer must be recalibrated if the reading varies from the bench-top spectrophotometer UVT reading by 2% or more. The recalibration must be conducted by a procedure recommended by the UVT analyzer manufacturer. 14. The flow meters measuring the flow through the UV reactor must be verified to determine accuracy on a monthly basis. The verification must compare the flow meter readings with other flow determination methods. 15. The TrojanUVSignaTM UV systems must be designed with a built-in automatic reliability feature that must be triggered by critical alarm setpoints. 16. Conditions that should trigger an alarm and startup the redundant bank of lamps include the following: a. the UV dose goes below 105% of the minimum UV dose, b. ballast failure and c. multiple lamp failure 17. Conditions that should divert effluent to waste include the following: a. UV dose is below the minimum UV dose, b. UVT is below the minimum UVT of 53.7%, c. UV intensity below the minimum validated of 1.11 mW/cm2 2 This UV dose equation assumes that the intensity sensors would measure the decline as the lamps age. Since there is one UV Intensity sensor for 8 lamps, the lamps should be rotated once a quarter to detect any decline in intensity due to aging. The lamp with the lowest intensity value should be closest to the UV sensor. If all of the lamp ages vary by less than 20 percent, the oldest lamp should be placed in the position nearest the UV sensor. Steve McDermid, TrojanUVSigna - 4 - March 17, 2017 d. complete UV reactor failure, and e. flow exceeds the maximum flow of 1,211 gpm/lamp. 18. The facility should be operated in accordance with an approved operations plan, which specifies clearly the operational limits and responses required for critical alarms. The operations plan should be submitted and approved prior to issuance of the operating permit. A copy of the approved operations plan should be maintained at the treatment plant and be readily available to operations personnel and regulatory agencies. A quick reference plant operations data sheet should be posted at the treatment plant and include the following information: a. The alarm set points for flow, UV dose, UV intensity, UVT, and power b. The values of flow, UV dose, UV intensity, and UVT when effluent must be diverted to waste. c. The required frequency of calibration for all meters/analyzers measuring flow, UV transmittance, and UV intensity. d. The required frequency of mechanical cleaning, equipment inspection, and replacement of cleaning solution. e. The UV lamp tracking procedures and replacement intervals. 19. The validation report did not address sleeve fouling. Each site should address the fouling potential of the wastewater. Each site must demonstrate proper cleaning procedures are in place. Proper maintenance and cleaning must be performed. The dose equation does not incorporate a fouling factor. This is not essential due to the fact that this reactor is proposed to be controlled via a calibrated germicidal sensor, which will account for the amount of lamp fouling in its intensity readings. However, the design engineer must consider fouling in the overall design capacity calculations. 20. Equivalent or substitutions of equipment should not be accepted without an adequate demonstration of equivalent disinfection performance. Review and acceptance of individual systems will be handled on a case-by-case basis by local District offices. Approval for the use of TrojanUVSignaTM UV Disinfection System in any and all water recycling applications is granted through the Regional Water Quality Control Board’s Water Reclamation permitting process.

Permits will contain specified times for said monitoring. 7.02.2 Automatic Re-Sampling Requirement. In the event that sample data indicates non- compliance with any District standard or limitation, said user will be required to resample for those pollutant parameters that indicate non-compliance and submit new analytical results within 30-days of receiving the initial sample results which indicated non- compliance. 7.02.3 Additional Monitoring. If the Industrial User monitors at the approved sample point(s) more often than required by the District, using approved sample collection methods and analytical procedures, then the results must be reported to the District within 30-days of receiving the results. The automatic re-sampling requirement also applies to any additional sampling that indicates non-compliance. 7.03 FLOW MONITORING EQUIPMENT A Significant Industrial User with an average daily discharge flow of more than 10,000 gallons per day shall install and operate a continuous monitoring flow meter capable of measuring the User's discharge to the District's sewerage system as part of its Monitoring Facilities. The flow measuring device shall be of a type appropriate to the quantity and characteristics of the discharge and shall be equipped with a flow indicator reading in gallons per minute (gpm) and a flow totalizer reading in gallons. If installation of a wastewater discharge flow meter is not practical, the General Manager may permit the User to install an approved water meter on the water line or lines supplying the process(es) that generate(s) the discharge. 7.04 PRETREATMENT OF FATS, OILS, AND GREASE 7.04.1 General. Each Enrollee shall evaluate its service area to determine whether a FOG pretreatment program is needed. If an Enrollee determines that a FOG pretreatment program is not needed, the Enrollee must provide justification for why it is not needed. If FOG is found to be a problem, the Enrollee must prepare and implement a FOG pretreatment control program to reduce the amount of these substances discharged to the sanitary sewer system. This plan shall include the following as appropriate: A. An implementation plan and schedule for a public education outreach program that promotes proper disposal of FOG; Page 44 East Valley Water District B. A plan and schedule for the disposal of FOG generated within the sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of FOG generated within a sewer system service area; C. The legal authority to prohibit discharges to the system and identify measures to prevent SSOs and blockage caused by FOG; D. Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, best management practice requirements, record keeping and reporting requirements; E. Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the FOG ordinance; F. An identification of sanitary sewer system sections subject to FOG blockage and establishment of a cleaning maintenance schedule for each section; and G. Development and implementation of source control measures for all sources of FOG discharged to the sanitary sewer system for each section identified in F above. 7.04.2 Legal Authority. The District’s FOG Control Program is supported by this Ordinance, which gives the District the legal authority to prohibit discharges into the sewer system, authority to require installation of pretreatment (i.e. grease removal devices), authority to inspect grease producing facilities and authority to enforce these provisions. 7.04.3 Best Management Practices A. Plan and Schedule for Disposal of FOG within the Service Area. The District does not own or operate any FOG disposal facilities. The FSEs must, at a minimum, collect waste FOG and prevent its discharge into the collection system by implementing the following BMPs to reduce the amount of FOG requiring disposal: 1. “Dry wipe” pots, pans, dishware, and work areas prior to washing. Use rubber scrapers or paper towels to remove FOG from cookware, utensils, and serving ware. 2. Use absorbent products to clean under fryer baskets and other locations where FOG may be spilled or dripped. Page 45 East Valley Water District B. For waste FOG that is generated, it must be collected and stored properly in recycling barrels or drums in accordance with EVWD requirements. FSEs must use a licensed hauler or recycling facility to dispose of this waste. FSEs must save receipts for the proper disposal, which are reviewed during an FSE inspection conducted by Pretreatment Inspectors and Assistants. 7.04.4 Gravity Interceptors. Each Industrial User discharging wastewater containing quantities of Oil and Grease and/or Suspended Solids that could exceed District standards set forth in Articles 4 and 5 herein shall install and maintain a gravity separation interceptor (interceptor) designed to retain all Oil and Grease that will float and any Suspended Solids that will settle. A. Vehicle and Equipment Servicing and Washing Facilities. Any facility maintained for the servicing, washing, cleaning, or repair of vehicles, roadway machinery, construction equipment, industrial transportation or power equipment, and which discharges nondomestic wastewater to the public sewer, shall install and maintain a gravity separation interceptor. The interceptor shall have no less than two compartments and shall have no less than three compartments if its operational fluid capacity is 100 gallons or greater. B. Food Processing Facilities. All food service establishments (FSEs), including processing facilities, are required to submit a Class III Restaurant User Permit Application to the District before discharging any wastewater to the sewer system. Upon review of the application, the District will notify the FSE whether an oil/grease interceptor is required. The District may elect to issue a Conditional Waiver or require a under sink grease trap as approved by the County of San Bernardino Department of Environmental Health Services, if it is determined that the FSE does not have the reasonable potential to cause an adverse effect on the POTW. However, the District may revoke the condition waiver for the following reasons: 1. Changes in menu; 2. Falsification of information in the Wastewater discharge survey form; 3. Changes in operating hours; 4. Changes in the maximum seating capacity; 5. Changes in the maximum meals served per peak hour; Page 46 East Valley Water District 6. Changes in the equipment used; 7. Changes in the quantity or quality of the wastewater discharged; 8. Increased sewer line maintenance or sanitary sewer overflows (SSOs) which are attributed to the restaurant user’s wastewater discharge. Interceptor Requirements. The design, construction, installation and testing of grease interceptors is determined by the California Plumbing Code as adopted by EVWD. The actual sizing of an interceptor is determined by the District. 1. Sanitary wastewater shall not be allowed to pass through the interceptor. 2. The interceptor shall have an operational fluid capacity that is not less than 100 gallons and is large enough to retain four (4) times the quantity of a seven-day accumulation of combined Oil and Grease and settled Suspended Solids. 3. The interceptor shall be watertight, structurally sound, durable and conform to District approved standards. 4. All interceptor chambers shall be immediately accessible at all times for the purpose of inspection and cleaning. At no time shall any material, debris, obstacles or obstructions be placed in such a manner so as to prevent immediate access to the interceptor. 5. All interceptors of 750 gallons capacity or larger shall be equipped with a sample chamber located at the downstream end of the interceptor and accessible at all times to District personnel for inspection and sampling. The sample chamber shall have a minimum 18-inch square opening. 6. Any interceptor legally and properly installed before the effective date of this Ordinance shall be acceptable as an alternative to the interceptor specified herein, provided such interceptor is effective in removing and retaining any Oil and Grease that will float and any Suspended Solids that will settle and is so designed and installed that it can be inspected and properly maintained. 7. If an interceptor is not effective in removing and retaining floatable Oil and Grease and settleable Suspended Solids, or is so designed and installed that it cannot be properly inspected or maintained, the User shall install, at the User's expense, an interceptor that complies with this Ordinance. Interceptor Maintenance. Any person who owns, operates, or maintains a gravity Page 47 East Valley Water District separation interceptor shall maintain it properly. A. The interceptor shall be cleaned as often as necessary to ensure that sediment and floating materials do not accumulate to impair the efficiency of the interceptor and odors do not cause a public nuisance. An interceptor is considered to be in violation under the following conditions: 1. Odors generated from the interceptor cause a public nuisance. 2. The interceptor is not in good working condition and appears to be surcharging or bypassing. 3. The operational fluid capacity of the interceptor has been reduced by more than twenty-five percent (25%) by the accumulation of floating material, sediment, solids, oil or grease. 4. The industrial wastewater discharged from the user is determined to contain more than 250 mg/L of oil and grease. 5. When an interceptor is cleaned, the interceptor must be pumped out completely and the removed sediment, liquid and floating material shall be lawfully disposed at a facility legally approved to accept such waste. 6. The user shall maintain a manifest for the removed interceptor waste. The manifest shall include at a minimum: the name and address of the facility where the waste is removed, the disposal site for the interceptor waste, the volume removed, and the date and time of removal. Failure to maintain and provide the required information may require the user to document the required information on an EVWD issued grease hauler manifest form. 7. The removed pretreatment waste shall not be reintroduced into the interceptor or discharged into another interceptor at another location which has not been approved by the District to accept such waste. 8. The use of chemicals to dissolve grease is specifically prohibited. When an interceptor is cleaned, the accumulated sediment and floating material shall be removed and legally disposed of otherwise than to the sewer. An interceptor is not properly maintained if for any reason it is not in good working condition or if the operational fluid capacity has been reduced by more than 25% by the accumulation of floating and settled solids, oils and grease. The owner, lessee, or sub-lessee, of any facility required to install an interceptor, and any proprietor, operator or superintendent of such facility are individually and severally liable for any failure of proper maintenance of such interceptor. Failure to maintain an interceptor or grease trap device is Page 48 East Valley Water District a violation of this Ordinance and subjects the User to progressive enforcement actions in accordance with the approved Enforcement Response Plan. B. Maintenance and BMPs for FSEs. 1. All FSEs are also required to comply with the following operation and maintenance requirements for grease traps: • Grease traps shall be cleaned on a daily basis. • A visual inspection of grease traps shall be conducted on a daily basis to check for leaking seams and pipes and ensure effective operation of the baffles and flow regulating device. • Grease traps and baffles shall be maintained free of all caked-on FOG and food waste. • Removable baffles shall be removed and cleaned out during the maintenance process. • Grease traps shall be maintained free of all food residues and any FOG waste dislodged during the cleaning and scraping process. • Any waste including FOG and solid material removed from the grease removal device shall not be discharged into the sanitary sewer. 2. All FSEs are required to implement BMPs to control the discharge of FOG to the sewer system and prevent SSOs. The BMPs are subject to approval by the District and at a minimum must include the following elements: • Dispose food waste directly into the trash or garbage and not in sinks. • Install drain screens on all drainage pipes. Periodically clean the screens and dispose screened solids into trash or garbage cans. • “Dry wipe” pots, pans, dishware and work areas prior to washing. Use rubber scrapers or paper towels to remove FOGs from cookware, utensils, and serving ware. • Collect waste cooking oil and store properly in recycling barrels or drums. Use a licensed hauler or recycling facility to dispose of this waste. • Use absorbent products to clean under fryer baskets and other locations where FOGs may be spilled or dripped. • Train kitchen staff and other employees to follow BMPs. • Post all applicable BMPs in the food preparation and/or dishwashing Page 49 East Valley Water District area. • Observe proper grease trap or interceptor cleaning and maintenance procedures to ensure the device is properly operating. • Comply with all other BMPs deemed appropriate by the District. 3. In the event an industrial user fails to comply with the requirements of this Ordinance, the District may take immediate enforcement action to reduce the risk of FOG entering the collection system by applying one or more appropriate enforcement action(s). The enforcement actions available to the District are outlined in Enforcement Response Plan (ERP), and an individual ERP may be developed for the non-compliant FSE. Interceptor Inspection. A.

INTRODUCTION On July 24, 1990 (55 Fed. Reg. 30082), the Environmental Protection Agency (EPA) promulgated regulations in Title 40 Code of Federal Regulations (CFR) 403.8(f)(5) which require all Publicly Owned Treatment Works (POTWs) to adopt an Enforcement Response Plan (ERP) as part of their approved pretreatment program. This requirement applies to POTWs that are issued National Pollutant Discharge Elimination System (NPDES) permits and have a design flow greater than 5 million gallons per day (mgd). East Valley Water District (District) will not be issued a NPDES permit as the Sterling Natural Resource Center (SNRC) will not discharge to a Water of the United States. However, SNRC will be issued a Waste Discharge Requirements permit for a Groundwater Replenishment Reuse Project (GRRP), which is required to have an enhanced source control program per Section 60320.106 of Title 22 of the California Code of Regulations (CCR). While the District is not required to develop an Enforcement Response Plan (ERP) to meet Title 40 CFR 403.8(f)(5), it is considered good practice to prepare one in order to meet the requirements of Title 22 CCR 60320.106. The ERP contains detailed procedures identifying how the Environmental Control (EC) Division of the District will investigate and respond to violations of State, and District wastewater pretreatment regulations. The ERP will be used by District personnel to carry out enforcement actions for pretreatment violations. The plan contains procedures indicating how the District will investigate and respond to instances of industrial user noncompliance. The ERP shall, at a minimum, include methods to: a. Describe how the District will investigate instances of noncompliance; b. Describe the types of escalating enforcement responses the District will take in response to all anticipated types of industrial user (IU) violations and the time periods within which responses will take place; c. Identify (by title) the official(s) responsible for each type of response; and d. Adequately reflect the District’s primary responsibility to enforce all applicable East Valley Water District Pretreatment Program Page 2 of 32 Enforcement Response Plan [INSERT DATE] pretreatment requirements and standards. The District’s EC Division is responsible for the development and implementation of the required ERP. All enforcement actions are progressive in nature and will escalate commensurate with the violation and response from the IU. The ERP is to be used as a reference to assist the EC Division with the appropriate level of enforcement response for similar violations. This ERP is a guidance document for District's staff and is not designed to be all inclusive and as such does not include every possible violation or corrective action(s) for the included violations. The purpose of the ERP in general, is to be flexible while being consistent in the approach to resolving noncompliance as quickly as possible. The District reserves the right to initiate enforcement actions at any level deemed necessary to protect the operation of the POTW, the safety of District employees, the environment and the public welfare. The District’s ERP endeavors to use terminology and definitions consistent with those found in Title 40 CFR 403.8 (f) (2) (viii) (A - H), Title 22 CCR 60320.106 and District Ordinance No. 389 “East Valley Water District Sewer Regulations and Service Charge Ordinance” (hereinafter referenced as Ordinance), which was adopted in 2014. Nothing in this ERP is intended to supersede or limit the District's rights and remedies under its Ordinance No. 389, or any successor thereto, or its rights and remedies under state law. The District issues IU Permits and requires sampling and inspection of their facilities. The District has adopted specific local wastewater discharge limits for pollutants of concern as well as Best Management Practices (BMPs). The District conducts wastewater monitoring and inspection activities to detect noncompliance at the IU sites. Inspections are conducted in both a scheduled and unscheduled manner. The majority of the sampling and inspections are unannounced. Wastewater discharge limitations are derived from applicable federal standards and the District’s adopted local discharge limits. The most stringent limits are enforced by the District. The discharge permit requires all permitted lUs to maintain compliance with the District’s discharge requirements, applicable State, and County regulations and the District’s Wastewater Ordinance No. 389, and amendments thereof. The objectives of the District’s ERP are: To define the range of enforcement actions based on the nature and severity of East Valley Water District Pretreatment Program Page 3 of 32 Enforcement Response Plan [INSERT DATE] the violation and other relevant factors; To identify the various enforcement options that the District will use in implementing the ERP; To identify the steps for tracking violations (from initiation to completion) once enforcement actions are initiated; To ensure the consistent and timely response to and resolution of all instances of noncompliance by the District; To eliminate any confusion or uncertainty concerning enforcement; To identify specific Environmental Control Division personnel who may initiate various enforcement actions; and To provide a fair and equitable means of enforcing the pretreatment regulations as set forth in the District’s Wastewater Ordinance No. [Insert Pretreatment Ordinance No.], and amendments thereof.

III. ENFORCEMENT PROCEDURES In order to achieve compliance by Industrial Users, the District uses a wide range of enforcement actions. The enforcement actions available to the District range from a simple reminder telephone call to termination of service and assessment of penalties. Some intentional violations may constitute criminal violations of Federal, State and District Law and the General Manager may seek the assistance of the EPA, the State or the District’s legal counsel to implement enforcement. The purpose of this section is to describe the range of available enforcement actions. The enforcement strategy is to begin enforcement at the lowest possible level (i.e., informal warnings either written or verbal) and escalate enforcement actions in a manner that is consistent with the severity and or frequency of the violation(s). However, the enforcement action is not always contingent upon the completion of lower level compliance requirements. Depending upon the nature of the violation, for instance a discharge which causes pass through or interference at a treatment plant warrants a higher-level procedure as an initial action. Written notices of violation are issued within 30 days of the Environmental Compliance Division becoming aware of the violation. East Valley Water District Pretreatment Program Page 10 of 32 Enforcement Response Plan [INSERT DATE] A. Enforcement Responses The District’s Wastewater Ordinance authorizes progressive enforcement steps to be taken in the resolution of violations to Federal, State, District Ordinance or wastewater permit conditions and requirements. The following list of enforcement responses summarizes the various actions authorized by District Ordinance No. [Insert Pretreatment Ordinance No.]. 1. Verbal Warnings: This informal level of enforcement may be issued by the EC Superintendent or an Inspector who may observe or learn of a violation which may be easily resolved by changing housekeeping practices or altering a discharge practice. This verbal warning is documented in an inspection report and by a written follow-up letter. The letter describes the violation encountered and requests that the industrial user correct the problem. The time frame for compliance may range from 14 to 30 days. Verbal warnings are generally given for conditions that, if not corrected, could lead to more serious violations (i.e., poor spill containment practices, improper maintenance of monitoring equipment, etc.) Follow-up inspections are used to verify compliance. 2. Written Warnings: This informal level of enforcement may be issued by the EC Superintendent or Inspector if an lU fails to achieve compliance after a verbal warning is issued with a date for achieving compliance. This notification reiterates the nature of the noncompliance and the need for corrective actions. The compliance date issued notifies the industrial user that compliance must be met by a set date. The time frame for compliance may range from 14 to 30 days. Follow-up inspections are used to verify compliance. 3. Notice of Violation (NOV): This level of enforcement may be issued by the E.C Superintendent or Inspector. A NOV may be issued whenever an industrial user’s noncompliance does not imminently endanger human health or welfare. The NOV shall be served in person by an employee/agent of the District, but preferably by an Inspector or by certified or registered mail, return East Valley Water District Pretreatment Program Page 11 of 32 Enforcement Response Plan [INSERT DATE] receipt requested. This is the first level of formal enforcement used for discharge violations and/or violations of BMPs. This level may be used to escalate enforcement actions against industrial users who have failed to comply with a written warning to correct deficiencies and/or violations. An III must provide, in writing (within ten working days from the date of receipt of the NOV), an explanation of the cause(s) of the violation(s) and a plan for the satisfactory correction of the violation(s). The written response shall include specific actions which the industrial user plans to take. Submission of such a plan in no way relieves the industrial user of liability for any violations occurring before or after receipt of the NOV. This action shall not limit the General Manager's authority to take or initiate any action, including emergency actions or any other enforcement action. 4. Compliance Meeting Order (CMO): A Compliance Meeting Order (CMO) shall be issued to an IU who has failed to achieve compliance after the issuance of an NOV, or at the conclusion of an NMP that has resulted in SNC. The CMO is an informal meeting between the IU and the EC Superintendent and is intended to provide the IU with the opportunity to propose corrective actions and if necessary, request an extension to comply with the NOV. The meeting allows the District to better assess the lUs good faith and to determine the next progressive step(s) necessary to achieve compliance (i.e., Consent Order, Compliance Order, etc.). The CMO may also be used to document the need to modify the Users Permit to include more monitoring, permit reclassification, or include other requirements to better monitor compliance. 5. Consent Order to Prepare a Specific Compliance Plan: A Consent Order is issued to an IU requiring a Specific Compliance Plan be developed to resolve a violation when the initial steps to correct a violation following receipt of an NOV has failed. The Consent Order is issued by the Inspector and/or the EC Superintendent. The specific compliance plan is developed in cooperation between the IU and the District. In other words, the District is consenting to allow the IU to have input regarding the corrective action time schedule, reporting requirements, etc. This type of East Valley Water District Pretreatment Program Page 12 of 32 Enforcement Response Plan [INSERT DATE] Order is also referred to as a Consent Order. The General Manager may be consulted regarding the final version. The Consent Order is generally reserved for those lUs who have demonstrated a willingness to correct violations. No element of specific compliance plan shall exceed six (6) calendar months in duration. Progress reports are required throughout the term of the specific compliance order. The minimum reporting frequency is thirty (30) calendar days. 6. Compliance Order with Compliance Time Schedule (CTS): A Compliance Order is adopted by the EC Superintendent and shall be approved by the General Manager which includes a final compliance date and intermediate milestone dates. The Compliance Order contains a CTS. Additionally, each Compliance Time Schedule consists of increments of progress called milestones. Each milestone is accompanied by specific deadlines for achievement of a specific task (i.e., for instance to begin construction, complete construction or achieve complete compliance). 7. Cease and Desist Order (CDO): Formal administrative enforcement order issued by the General Manager which requires the Industrial User to cease violating or threatening to violate Categorical Standards or pretreatment requirements immediately or in accordance with a Compliance Time Schedule. Cease and Desist Orders (CDOs) are to be issued after review by, and meeting with, the industry. When the District finds that the provisions of the Ordinance or other Rules and Regulation of the District have been violated, or are threatened to be violated, the General Manager, or his designated agent, may issue an order to cease and desist, and direct that person not complying with the Ordinance or the Rules and Regulations to: a. Comply with a time schedule set forth by the District; or b. In the event of a threatened violation, take appropriate remedial or preventive action. Requirements of a Cease and Desist Order (CDO) are enforceable by the assessment of Civil Penalties or by termination of service. East Valley Water District Pretreatment Program Page 13 of 32 Enforcement Response Plan [INSERT DATE] 8. Order to Implement Noncompliance Monitoring Program (NMP): A program of additional sampling and reporting by the User in accordance with a schedule issued by the General Manager. During this program the User may be subject to noncompliance fees established by District Ordinance or Resolution for any violation of pollutant limits or for failure to submit a wastewater analysis report in accordance with the schedule. 9. Permit Suspension Order: The General Manager may suspend an Industrial User’s Industrial User Permit, when the Industrial User violates the Ordinance, an administrative order, or any applicable state or federal law. Non-compliant Industrial Users shall be notified of the proposed Suspension Order of their Industrial User Permit. Notice shall be served on the Industrial User specifying the time and place for a hearing, the proposed enforcement action, the reasons for such action, and a request that the Industrial user show cause why the proposed action should not be taken. The notice of the hearing shall be served personally or by registered or certified mail, return receipt requested, at least ten (10) days prior to the hearing. 10. Permit Termination Order: The General Manager may terminate an Industrial User’s Industrial User Permit, when the Industrial User violates the Ordinance, an administrative order, or any applicable state or federal law. Non-compliant Industrial Users shall be notified of the proposed Termination Order of their Industrial User Permit. Notice shall be served on the Industrial User specifying the time and place for a hearing, the proposed enforcement action, the reasons for such action, and a request that the Industrial user show cause why the proposed action should not be taken. The notice of the hearing shall be served personally or by registered or certified mail, return receipt requested, at least ten (10) days prior to the hearing. 11. Administrative Complaint: The General Manager may issue an Administrative Complaint to any person who violates the Ordinance; Categorical Standards; a Permit requirement; East Valley Water District Pretreatment Program Page 14 of 32 Enforcement Response Plan [INSERT DATE] or an order issued pursuant to a Notice of Violation. The Administrative Complaint shall allege the act or failure to act that constitutes the violation, the provisions of law authorizing civil liability to be imposed, and the proposed civil penalty. The Administrative Complaint shall be served by personal delivery or certified mail and shall inform the person served that a hearing shall be conducted within 60 days after the person has been served. The hearing shall be before the General Manager. The person who has been issued an Administrative Complaint may waive the right to a hearing, in which case the District shall not conduct a hearing. A person dissatisfied with the decision of the General Manager may appeal to the District's Board within 30 days of notice of the hearing officer's decision. Failure to appeal within such 30-day period shall be deemed a waiver of such appeal right, and the judicial review rights set forth in Section 10.02.2. 12. Civil Penalties: If after a hearing, or appeal, if any, it is found that the person has violated the Ordinance, Categorical Standards, a Permit Requirement or an order issued pursuant to a Violation, the hearing officer or the Board of Directors may assess a civil penalty against that person. In determining the amount of a civil penalty, the hearing officer or the Board of Directors shall take into consideration all relevant circumstances including, but not limited to, the extent of harm caused by the violation, the economic benefit derived by the person causing the violation, the nature and persistence of the violation, the length of time over which the violation occurs and corrective action, if any, attempted or taken by the person causing the violation. a. Civil penalties may be imposed as follows: 1. In an amount which shall not exceed $2,000.00 for each day for failing or refusing to furnish technical or monitoring reports [Government Code, Section 54740.5(d)(1)]; 2. In an amount which shall not exceed $3,000.00 for each day for failing or refusing to timely comply with any compliance schedule established by the General Manager [Government Code, Section East Valley Water District Pretreatment Program Page 15 of 32 Enforcement Response Plan [INSERT DATE] 54740.5(d)(2)]; 3. In an amount which shall not exceed $5,000.00 per violation for each day for discharges in violation of any waste discharge limitation, permit condition, or requirement issued, reissued or adopted by the District [Government Code, Section 54740.5(d)(3)]; 4. In an amount which does not exceed $10.00 per gallon for discharges in violation of any suspension, cease and desist order or other orders, or prohibition issued, reissued or adopted by the General Manager [Government Code, Section 54740.5(d)(4)], b. Unless appealed to the Board, orders setting administrative civil penalties shall become effective and final upon issuance thereof, and payment shall be made within 30 days. Copies of these orders shall be served by personal service or by registered mail upon the parties served with the administrative complaint and upon other persons who appeared at the hearing and requested a copy. c. All monies collected under this Section shall be deposited in a special account of the District and shall be made available for the monitoring, treatment and control of discharges into the Sewerage System or for other mitigation measures. d. The amount of any civil penalties imposed under this Section which have remained delinquent for a period of 60 days shall constitute a lien against the real property of the discharger from which the discharge originated resulting in the imposition of the civil penalty. The lien shall be recorded with the County Recorder and when recorded shall have the force and effect and priority of a judgment lien and continue for 10 years from the time of recording unless sooner released and shall be renewable in accordance with the provisions of Sections 683.110 to 683.220, inclusive, of the Code of Civil Procedure. e. No penalties shall be recoverable under this Section for any violation for which civil liability is recovered under Section 10.03 of the District’s Ordinance No. [Insert Pretreatment Ordinance No.] East Valley Water District Pretreatment Program Page 16 of 32 Enforcement Response Plan [INSERT DATE] 13. Judicial Review: Any party aggrieved by a final order issued by the District's Board under Section 10.02.1 of Ordinance No. [Insert Pretreatment Ordinance No.], may obtain review of the order of the Board in the Superior Court by filing in the Court a petition for writ of mandate within 30 days following the service of a copy of a decision and order issued by the Board. Any party aggrieved by a final order of a hearing officer issued under Section 10.02.1 of Ordinance No. [Insert Pretreatment Ordinance No.] for which the Board denies review, may obtain review of the order of the hearing officer in the Superior Court by filing in the Court a petition for writ of mandate within 30 days following service of a copy of a decision and order denying review by the Board. If no aggrieved party petitions for writ of mandate within the time allowed, an order of the Board shall not be subject to review by any Court or agency. The evidence before the Court shall consist of the record before the Board, including the hearing officer's record, and any other relevant evidence which, in the judgment of the Court, should be considered to effectuate and implement policies of District Ordinance No. [Insert Pretreatment Ordinance No.], as amended.

However, a single reward payment may not exceed $2,500.00. f. Remedies Non-Exclusive. The remedies provided for in the District Ordinance are not exclusive. The General Manager may take any, all, or any combination of these actions against the non-compliant User. Enforcement of pretreatment violations will generally be in accordance with the District's Enforcement Response Plan. However, the General Manager may take other action against any User when the circumstances warrant. Further, the General Manager is empowered to take more than one enforcement action against any noncompliance User. 19. Illegal Connection: Any connections made to the Sewer System without complying with the Ordinances, Rules and Regulation and paying all fees and charges as required is illegal and a public nuisance. a. The District may enter property and disconnect any illegal connection from the Public Sewer. Should disconnection be necessary all cost incurred by the District including reasonable attorney's fees shall be recovered by the District. East Valley Water District Pretreatment Program Page 21 of 32 Enforcement Response Plan [INSERT DATE] b. At the discretion of the Board, after application for a permit is made, connection may be allowed to continue by first determining that no harm has been done by the connection, or if the connection was properly made. c. Any repairs must be fully effected at the sole expense of the User and a penalty of double the permit, inspection, and connection fees as established by the Ordinance be paid. d. In addition, all unpaid sewer service charges, assessments or other charges shall be computed from the date the illegal connection was made and shall be paid by the User. 20. Protection from Damage: No unauthorized person shall intentionally or negligently break; damage; destroy; uncover; deface; or tamper with any structure, appurtenance or equipment which is a part of the Sewer System. Any person violating this provision shall be guilty of a misdemeanor and subject to the penalties provided by law. 21. Falsifying Information: Any User who knowingly makes any false statements, representation, record, report, plan or other document filed with the District or who falsifies, tampers with, or knowingly renders inaccurate any monitoring devise or method required under the Ordinance shall be guilty of a misdemeanor and subject to the penalties provided by law. Any User who knowingly makes any false statements, representations, or certifications in any application, record, report, plan or other document filed or required to be maintained pursuant to the Ordinance or the User's wastewater discharge permit, or who falsifies, tampers with, or knowingly renders inaccurate any monitoring device or method required under the Ordinance shall, upon conviction, be punished by a fine of not more than One Thousand Dollars ($1,000.00) per violation per day or imprisonment for not more than six months, or both for each violation. This penalty shall apply to the exclusion of any other Ordinance provisions more lenient. East Valley Water District Pretreatment Program Page 22 of 32 Enforcement Response Plan [INSERT DATE] 22. Termination of Service: The District, after a hearing by the Sewer Committee or the Board of Directors, may revoke any wastewater discharge permit, or terminate or cause to be terminated wastewater service to any building if a violation of any provision of the Ordinance causes or threatens to cause a condition of contamination, pollution, or nuisance as defined in the Water Code. This provision is in addition to other statutes, rules, or regulations, authorizing termination of service for delinquency in payment. 23. Payment of Fees, Charges and Penalties: In the event that any enforcement action is brought by the District, the Owner or User shall pay to the District reasonable attorney's fees and all costs associated with said actions. a. Unless otherwise specified, all penalties imposed pursuant to the Ordinance are due and payable within thirty calendar days of receipt of notice or invoicing by the District. b. Any invoice outstanding and unpaid after ninety days shall be cause for immediate suspension of the wastewater discharge permit. In addition, interest shall accrue on any unpaid penalties at ten percent (10%) per annum from the due date until paid. c. Payment of disputed charges is still required by the due date during the General Manager's review of any appeal submitted by the User. 24. Damage to Facilities or Interruption of Normal Operations: Any User who discharges any waste which causes or contributes to any obstruction, interference, damage, or any other impairment to the District's Sewer System or tributaries thereto or to the operation of those facilities shall be liable for all costs required to clean or repair the facilities together with expenses incurred by the District to resume normal operations. Such discharges shall be grounds for permit revocation. A service charge of twenty-five percent (25%) of the District's costs shall be added to the costs and charges to reimburse the District for miscellaneous overhead, including administrative personnel and record keeping. The total amount shall be East Valley Water District Pretreatment Program Page 23 of 32 Enforcement Response Plan [INSERT DATE] payable within thirty (30) days of invoicing by the District. Any User who discharges a waste which causes or contributes to the District violating its discharge requirements established by any Regulatory Agency and causing the District to incur additional expenses or suffer losses or damage to its facilities, shall be liable for any costs or expenses incurred by the District, including regulatory fines, penalties, and assessments made by other agencies or a court. B. Determining Factors 1. Magnitude of the violation: The level of enforcement action depends on the magnitude of the violation and/or any significant threat to the public health, safety, welfare, the environment, the POTW, or any District personnel. 2. Duration of the violation: The length of time a violation exists without being corrected also impacts the level of enforcement response. Violations that are not corrected within a specified time frame will result in escalated enforcement responses. 3. Compliance History of the User: The initial level of enforcement may also be determined by the compliance history of the User. Repeat violations within specified time frames, indicating chronic noncompliance, generally will be addressed at higher levels of response and may be accompanied by a change in permit classification which increases the District’s oversight and places additional requirements on the User to demonstrate assurance of continued compliance. 4. Good Faith of the User: Additional considerations are given in the enforcement response to Users that demonstrate reasonable and consistent approaches to resolving noncompliance such as quick responses to noted violations; installation of equipment and/or implementation of best management practices, etc. in good faith attempts to resolve noncompliance. East Valley Water District Pretreatment Program Page 24 of 32 Enforcement Response Plan [INSERT DATE] 5. Effect of the Violation: The initial response to a violation also considers the effect or impact of any noncompliance on the District. For example, any violation that meets the definition of Significant Noncompliance (SNC) or jeopardizes the designated beneficial reuse of treated wastewater or municipal sludge (biosolids), or that compromises the District’s ability to meet any federal, state, or local regulatory requirements requires an elevated response to assure quick resolution. C. Enforcement Response Guide The District will identify non-compliance with permit and Ordinance provisions through the following: 1. Industrial User Inventory - An essential step for identifying non- compliance is, knowing who is discharging non-domestic waste to the POTW, where they are located, and the nature of the non- domestic waste being discharged. The Environmental Control Division maintains a current inventory of all non-domestic sources of waste to the POTW. 2. Monitoring and Inspection Plan - The Environmental Control Division monitors the wastewater from each Industrial User at least once per year. Sampling procedures include Quality Assurance/Quality Control procedures discussed elsewhere in the approved pretreatment program, are followed to maximize sample integrity. All inspections are performed using approved District forms that include checklists and narrative sections to document the non-compliance; the section of the permit or Ordinance that governs compliance for that specific area; timeframe(s) for responding to the violation; and the next level of enforcement to expect if the noncompliance is not corrected. 3. Compliance Screening - All reports from Industrial Users are carefully reviewed on an as received basis for timeliness, completeness and accuracy. The screening process includes an evaluation of compliance with report due dates, numerical standards, sampling handling and analysis requirements, signatory/certification East Valley Water District Pretreatment Program Page 25 of 32 Enforcement Response Plan [INSERT DATE] requirements, Best Management Practices (BMPs) used as outlined from time to time and monitoring frequency. All violations are clearly documented and addressed in accordance with the Enforcement Response Plan.

Geoscience Support Services, Inc. (Geoscience) has been retained to perform a hydrogeological analysis of this proposed recycled water discharge site using groundwater modeling and to evaluate compliance with existing requirements in Article 5.1 Indirect Potable Reuse: Groundwater Replenishment – Surface Application, Section 60320 of Title 22 California Code of Regulations (CCR) for recycled water recharge. 1.2 Purpose and Scope The purpose of the groundwater model runs is to evaluate compliance with existing requirements in Title 22 CCR. Specifically, the groundwater model was used to evaluate the following elements under Scenario Weaver Basin: • Travel Distance of Recycled Water – Model-predicted travel distance for recycled water after 12 months, 10 years, and 20 years of project recharge • Well Control Zone – Model-predicted travel distance for recycled water after 14 months of project recharge to delineate well control zone boundaries • Recycled Water Contribution (RWC) – Model-simulated areal distribution of percent of recycled water after 12 months, 10 years, and 20 years • Retention Time of Recycled Water – Model-predicted time for recycled water to reach active production wells • Percent of Recycled Water Contribution – Model-simulated recycled water percentage at potentially impacted wells Sterling Natural Resource Center Project Hydrogeological Analysis and Modeling Results for Scenario Weaver Basin 23-Apr-21 2 2.0 REFINED BASIN GROUNDWATER FLOW MODEL The model used for the hydrogeological analysis is the Refined Basin Flow Model (RBFM), which was developed jointly by the City of San Bernardino Municipal Water Department (SBMWD) and San Bernardino Valley Municipal Water District (Valley District). The RBFM is an integrated streamflow, groundwater flow, and solute transport model developed for the SBBA (approximately 524 square miles), including the Bunker Hill and Lytle Basins. The RBFM is a five-layered, finite difference model with a cell size of 102.5 ft by 102.5 ft. The model layers include: • Layer 1: Upper Confining Member (UCM) and Upper Water Bearing (UWB), • Layer 2: Middle Confining Member (MCM), • Layer 3: Middle Water Bearing (MWB), • Layer 4: Lower Confining Member (LCM), and • Layer 5: Lower Water Bearing (LWB) The primary recharge components of the model include seepage from gaged streams, seepage from ungagged runoff, direct infiltration of precipitation, recharge from local runoff (i.e., runoff originating from precipitation), artificial recharge of imported water , return flow from groundwater pumping, and underflow inflow from upgradient groundwater basins. The primary discharge terms are groundwater extraction, evapotranspiration, and subsurface outflow. The relative error of the calibrated RBFM is approximately 4.6%, which is within the industry standard of 10%. The model is most sensitive to hydrologic conductivity and streambed conductance, moderately sensitive to variations in underflow outflow, and locally sensitive to variations in groundwater barrier conductance. A more detailed description of the RBFM is provided in the model report prepared by Geoscience (2009). Variation in hydrologic conditions (i.e., precipitation and associated recharge) allows potential SNRC project impacts to be evaluated under various natural recharge conditions. The predictive scenarios were conducted using the 25-year period from January 1966 through December 1990. This hydrologic base period was chosen because it represents average hydrologic conditions and includes wet and dry hydrologic periods (Figure 2). This period also corresponds to the period identified by the Habitat Conservation Plan (HCP) Hydrology technical advisory committee (TAC) as the HCP base period. Groundwater pumping for the 25-year predictive period was based on projections reported in the “2015 San Bernardino Valley Regional Urban Water Management Plan” (WSC, 2016). Initial water levels for Sterling Natural Resource Center Project Hydrogeological Analysis and Modeling Results for Scenario Weaver Basin 23-Apr-21 3 predictive scenarios were based on the 2020 groundwater elevation provided by Valley District and East Valley Water District (EVWD). MODPATH, a post-processing package, is used to compute travel distance and retention time of recycled water from the recharge site to the nearest active municipal wells. MODPATH does not take into account dispersion, retardation, or half-life decay. Results from MODPATH simply provide an indication of the direction and speed of groundwater flow. The amount of underflow as blended water at active production wells was quantified based on the results from MT3DMS. MT3DMS is a modular, three-dimensional, multispecies solute transport model for the simulation of advection, dispersion, and chemical reactions of contaminants in groundwater systems. In simple terms, the initial concentration of recharged recycled water is assigned a value of 100 while the concentration of the receiving groundwater (i.e., background) is assumed to be zero. If the concentration of recycled water at an active production well is predicted to be 20, then the underflow accounts for 80% and Project recycled water accounts for 20% of the blended water. Sterling Natural Resource Center Project Hydrogeological Analysis and Modeling Results for Scenario Weaver Basin 23-Apr-21 4 3.0 PREDICTIVE MODEL OPERATIONAL SCENARIOS 3.1 Description of Model Scenarios One predictive model run was performed using the RBFM to provide a hydrogeological assessment of proposed recharge at Weaver Basin. The model run was simulated for a period of 25 years, as described above, with a monthly stress period. The simulation period begins in model year 2022, which corresponds to hydrologic year 1966. The model scenario used the following assumption for recycled water discharge: • Scenario Weaver Basin: Discharge of 8 million gallons per day (MGD) of recycled water into Weaver Basin Annual recycled water discharge for Scenario Weaver Basin is shown on Figure 3. 3.2 Groundwater Recharge Facility The location of the proposed Weaver Basin is shown on Figure 1. Properties of the proposed Weaver Basin site are summarized in Table 3-1 below. Table 3-1. Summary of Proposed Project Discharge Facility Proposed Discharge Facility Effective Recharge Area1 [acres] Estimated Infiltration Rate2 [ft/day] Recharge Capacity3 [MGD] Depth to Groundwater4 [ft] Vadose Zone Travel Time5, 6 [days] Weaver Basin 15 7.6 37.1 113 15 Notes: 1 Represents the approximate width and length of the effective recharge area. 2 Long-term infiltration rate was assumed to be 20% of the percolation test results (38 ft/day), which were performed by Scheevel Engineering in October 2020. 3 Calculated by multiplying effective recharge area by infiltration rate and converted to MGD. 4 Based on 2020 water levels. 5 Vadose zone represents the partially saturated or unsaturated regions between the ground surface and water table. 6 Vadose zone travel time equals the depth to groundwater divided by the estimated infiltration rate. 3.3 Nearby Active Municipal Water Supply Wells Locations of nearby active municipal water supply wells and other wells (private, monitoring, etc.) are shown on Figure 4. Details and construction information for the nearest active downgradient municipal water supply wells to the proposed Weaver Basin are summarized in the following Table 3-2. After some preliminary model runs, it was found that four active municipal wells (EVWD Plant No. 143, EVWD Plant Sterling Natural Resource Center Project Hydrogeological Analysis and Modeling Results for Scenario Weaver Basin 23-Apr-21 5 No. 146, EVWD Plant No. 146A, and EVWD Plant No. 147) were too close to Weaver Basin (less than 2,000 ft) to meet the CCR Title 22 Regulatory requirements. Therefore, these four wells were assumed to be inactive in final Scenario Weaver Basin model run. Table 3-2.

Sterling Natural Resource Center Project Hydrogeological Analysis and Modeling Results for Scenario Weaver Basin 23-Apr-21 6 4.0 MODEL RESULTS This section presents results for the assessment of potential impacts of Project Scenario Weaver Basin on underground retention times and RWC at down-gradient active municipal water supply wells. The groundwater flow and solute transport model (i.e., RBFM) was used to evaluate the following for Scenario Weaver Basin: • Predicted travel distance and seepage velocity of recycled water after 12 months, 10 years, and 20 years of Project recharge. • Model-predicted travel distance for recycled water after 14 months of project recharge to delineate the well control zone boundary. • Predicted distribution of percent recycled water after 12 months, 10 years, and 20 years of Project recharge. • Predicted underground retention time and percentage of RWC at the nearest active municipal water supply wells. 4.1 Predicted Travel Distance and Seepage Velocity of Recycled Water Figure 4 shows the model-predicted travel distance for recycled water after 12 months, 10 years, and 20 years of Project recharge under Scenario Weaver Basin conditions. Table 4-1 below summarizes predicted travel distances and estimated travel velocities (i.e., seepage) of the recharged recycled water. Table 4-1. Model-Predicted Travel Distance and Seepage Velocity – Scenario Weaver Basin Time Since Start of Recycled Water Discharge [years] Maximum Travel Distance [ft] Maximum Travel Distance [ft/day] Active Municipal Water Supply Wells Reached by Recycled Water 1 (12 months) 4,600 13 None 10 (120 months) 21,700 6 None 20 (240 months) 28,900 4 3 As shown, recycled water is not anticipated to reach any of the closest active municipal wells located downgradient of Weaver Basin within the first 10 years (120 months) of Project recharge. After 20 years (240 months), recycled water reaches three (3) active downgradient municipal supply wells. Sterling Natural Resource Center Project Hydrogeological Analysis and Modeling Results for Scenario Weaver Basin 23-Apr-21 7 4.2 Well Control Zone As specified in Section 60320.200 subsection (e) of Title 22, GRRP (Groundwater Reuse and Recharge Project) regulations request the establishment of a boundary representing a zone of controlled drinking water well construction (well control zone). Pursuant to Sections 60320.208 and 60320.224, model- predicted travel distance for recycled water after 14 months of Project recharge for Scenario Weaver Basin was used to delineate the well control zone boundary (Figure 5). 4.3 Predicted Distribution of Percent Recycled Water Figures 6, 7, and 8 present model-simulated contours of percentage of recycled water in the aquifers at the end of 12 months, 10 years, and 20 years of Project recharge for Scenario Weaver Basin. The infiltrated recycled water will blend with groundwater (i.e., diluent) and flow downgradient towards active municipal wells within each primary unit of the aquifer system. In the vicinity of Weaver Basin, recycled water is predicted to percolate into the UCM/UWB (layer 1), MCM (layer 2), and, to a lesser degree, MWB (layer 3) and LCM (layer 4) after 12 months of Project recharge. After 10 and 20 years of Project recharge (Figures 7 and 8, respectively), percolating recycled water is seen within all five model layers. 4.4 Predicted Recycled Water Retention Time and Recycled Water Contribution CCR Title 22 Regulations, Section 60320.124 (c) - Response Retention Time of the Draft Regulations for Groundwater Replenishment Reuse states: “The retention time shall be the time representing the difference from when water with the tracer is applied at the GRRP to when ten percent (10%) of the peak tracer unit value observed at the downgradient monitoring point reaches the monitoring point.” Stated another way, the retention time is the minimum amount of time the recycled water exists in the groundwater basin prior to being extracted. As an alternative to utilizing a tracer study 1 , the regulations allow for the application of a calibrated numerical groundwater flow model to estimate retention time. As stated in the regulations, the minimum retention time shall be no less than two (2) months (Section 60320.124 (b)). However, Table 60320.108 only gives a virus log reduction credit per month2 of 0.50 logs when retention time is determined using numerical modeling. This means that when models are used, a minimum four(4)-month retention time must be determined between the GRRP site and the nearest water supply well. 1 CCR Title 22 Regulations, Subsection (c) of Section 60320.124 states: “A project sponsor for new GRRP (Groundwater Replenishment Reuse Project) shall initiate the tracer study prior to the end of the third month of operation.” 2 Section 60320.208 (b) states that for each month retained underground, municipal wastewater will be credited with 1-log virus reduction. Sterling Natural Resource Center Project Hydrogeological Analysis and Modeling Results for Scenario Weaver Basin 23-Apr-21 8 Using the RBFM, retention time was calculated as the minimum time for recharged recycled water to reach an active downgradient municipal water supply well, which is an indicator for the amount of time the recycled water exists in the groundwater basin prior to being extracted. The percentage of groundwater underflow at the nearest active municipal supply wells was quantified based on the results from MT3DMS. For modeling purposes, the initial concentration of recycled water recharged was assigned an arbitrary value of 100, and the concentration of the receiving groundwater (i.e., diluent) was assumed to be zero. The model then calculated the RWC for the nearest downgradient active municipal wells (refer to Table 3-2 for a list of wells). CCR Title 22 Regulations stipulate an initial maximum RWC not to exceed 20% over a 120-month (10-year) period (Section 60320.116). It should be noted that the cyclic nature of the RWC shown on the individual well charts reflects contribution of more natural and/or artificial recharge (stormwater capture) as diluent water. Plots of model-calculated RWC for each model layer in the nearest active municipal supply wells after 25 years3 of recycled water recharge at the proposed Weaver Basin are shown on Figure 9. Results from the modeling indicate that the minimum retention time of four months is met under Scenario Weaver Basin. The initial maximum RWC is shown to exceed 20% in layers 1 through 3 at N. Orange Well #1, approximately 6 years from the start of recharge operation, which is within the 120-month period. Table 4-2 below summarizes model-predicted underground retention times and RWC at the nearest active municipal supply wells located downgradient of Weaver Basin under Scenario Weaver Basin conditions. 3 As discussed in Section 2.0, the predictive scenario was performed for a 25-year period which covers average hydrologic conditions (including both wet and prolonged dry climatic cycles).

Sterling Natural Resource Center Project Hydrogeological Analysis and Modeling Results for Scenario Weaver Basin 23-Apr-21 11 5.0 FINDINGS The results of this study indicate that: • Based on particle tracking and distribution of percent recycled water performed for Scenario Weaver Basin, recharged Project water will percolate into the underlying aquifers, blend with groundwater, and travel away from the Project discharge facility (Weaver Basin) towards the nearest active municipal supply wells. • Average seepage velocities in the vicinity of the nearest active municipal supply wells located downgradient of Weaver Basin range from approximately 4 to 13 ft/day for Scenario Weaver Basin. • The Project would achieve a minimum of 14 months of underground retention time for Scenario Weaver Basin, which meets the CCR Title 22 Regulations • Based on MT3DMS, the percentage of recycled water would reach 20% in six years for N. Orange Well #1 under Scenario Weaver Basin conditions.

N/A Monitor 1 East Valley Water District Woodard & Curran Title 22 Engineering Report November 2021 APPENDIX G: WATERSHED CONNECT BROCHURE Watershed Connect Achieving resilience through integrated infrastructure PROGRAM DESCRIPTION BENEFITS WATERSHED CONNECT is a regional infrastructure program, a network of forward-looking projects designed to achieve water supply reliability, climate resilience, and long-term ecological health of the Upper Santa Ana River (Upper SAR) Watershed. WATERSHED CONNECT is a multiphase program comprised of interconnected water capture, recharge, storage, treatment, and conveyance projects. This comprehensive package of infrastructure projects will collectively maximize the use and reuse of local water resources, while attaining a healthy, functional river ecosystem that supports 22 federally and state-protected species. WATERSHED CONNECT’s innovative approach maximizes program value and offers synergistic benefits to the watershed and its people. The Upper Santa Ana River Watershed Infrastructure Financing Authority (USAR WIFA) is a Joint Powers Authority comprised of San Bernardino Valley Municipal Water District, San Bernardino Valley Water Conservation District, Western Municipal Water District, Western Entities, City of Colton, City of San Bernardino Municipal Water Department, Big Bear Area Regional Wastewater Agency, and the Yucaipa Valley Water District. The participants, all of whom rely upon the highly connected tributaries, groundwater basins, and natural ecosystems of the Santa Ana River, have come together as stewards of the watershed to ensure funding is available to secure a reliable and sustainable water future for nearly 1 million people in the San Bernardino and Riverside Counties. The program reflects the region’s long-standing commitment to integrated water resource management. Through efforts such as the Upper SAR Watershed Integrated Regional Urban Water Management Plan (IRUWMP), the Upper SAR Habitat Conservation Plan, the Regional Recycled Water Concept Study, and the Upper SAR Integrated Groundwater/Surface Flow Model, water agencies in the Upper SAR Watershed continue to collaborate across traditional boundaries to build much needed water infrastructure, create and support jobs and the local economy, care for shared resources and accomplish a common goal; a secure, equitable, and reliable water supply for the region. PROGRAM PURPOSE The purpose of the program is to achieve regional water supply security, resilience to extended drought and the effects of climate change and holistically enhance the health of the Upper SAR Watershed. The Upper SAR Watershed, spanning over 850 square miles in San Bernardino and Riverside Counties in southern California, is a highly connected system of surface water, groundwater, and rich habitat that the region depends on for its local water supply. For many years, the San Bernardino Valley has been challenged by prolonged drought, increased wildfires, and climate uncertainty. In response, the region, which relies heavily on imported water, is investing in collaborative solutions to diversify its water supply portfolio, recharge its groundwater basins, restore critical habitat and secure a sustainable water future. WATERSHED CONNECT will capture over 38,000 AFY of stormwater runoff, produce and distribute over 25,000 AFY of recycled water for groundwater recharge, restore over 870 acres of habitat, create 830 acres of open space, and generate over 1,300 kW of renewable energy within the Upper SAR Watershed. This integrated program offers the following benefits to the region: Resiliency in the face of climate change: The collection of forward- looking recycled water, stormwater capture, groundwater storage, alternative energy, and ecosystem restoration projects will improve water supply security. Investments in alternative water supplies, emergency storage, and system redundancies enhance the region's resilience to climate threats. Infrastructure Enhancements: Modernization of existing infrastructure combined with new conveyance systems are planned to create enhanced water resources. Upgrades, including pipeline protection initiatives and solar energy projects, will reduce climate-related vulnerabilities and ensure reliable services during natural disasters. Drought Resiliency: The program’s ambitious stormwater capture, groundwater recharge, and water reuse projects position the region to sustain short and long-term droughts. Improved Water Quality: Advanced treatment upgrades will improve regional water quality by reducing the amount of salt, nutrients, and emerging contaminants introduced to surface waters and groundwater basins. Proposed stormwater capture and treatments projects will produce high-quality water for blending with groundwater supplies high in total dissolved solids. Ecological Health: Planned habitat mitigation and restoration initiatives will holistically enhance the ecological health of the Upper SAR Watershed, supporting the region’s urban, environmental, recreational, and economic needs. 36 C E D Upper Santa Ana River Watershed Upper Santa Ana Valley Groundwater Basin Subbasins 24” Recycled Water Pressure Zone 11 Regional Pipeline 3.0 MG R-11.4 Recycled Water Reservoir Active Recharge – Devil Crk.
