Ready, City Manager Initiated by: Engineering Services Department SUMMARY The proposed action will approve the First Amendment to the Wastewater Services Agreement for operation and maintenance with Veolia Water West Operating Services, Inc., to develop and implement a Municipal Industrial Pretreatment Program (MIPP) and authorize the City Manager to issue a Purchase Order to Veolia Water West Operating Services for completion of various studies required by the California Regional Water Quality Control Board Order R7-2017-0013, regulating operations of the City's Waste Water Treatment Plant. RECOMMENDATION: 1) Approve the First Amendment to the Wastewater Services Agreement (O&M) dated of November 4, 2015, (Agreement No. 6804) by and between the City of Palm Springs and Veolia Water West Operating Services Inc.; and 2) Authorize the issuance of a Purchase Order in the amount of $145,636 to Veolia Water West Operating Services, Inc., for preparation of various technical studies required by the California Regional Water Quality Control Board pursuant to its Order R7-2017-0013; and 3) Authorize the City Manager to execute all necessary documents. Ci'EM NO. .1 .1 . City Council Staff Report November 1, 2017—Page 2 Approval of First Amendment to the Wastewater Services Agreement(O&M) Veolia Water West Operating Services Inc. BACKGROUND: Beginning in 1999 the City has utilized private contractors to provide operation and maintenance services associated with its Wastewater Treatment Plant (the "WWTP"), the sanitary sewer collection system, the sanitary storm sewer system, and administration of various related programs (Sewer Services). The City entered into a contract with US Filter, subsequently Veolia Water North America Operating Services, Inc. (Veolia) to provide Sewer Services for an initial term through June 30, 2005. Various amendments were made during the life of the Agreement. Most recently, on November 4 2015, City Council approved a new Wastewater Services Agreement for operation andAmaintenance with Veolia, which commenced on January 1, 2016, for an initial term of 5 years through December 31, 2020, with two 5-year optional extended terms available at the City's sole discretion. The City's WWTP has been operating under regulations issued by the California Regional Water Quality Control Board, Colorado River Basin Region (RWQCB) through its Waste Discharge Requirements (WDRs) Order No. 93-076, adopted on November 17, 1993. On September 21, 2017, the RWQCB adopted new regulations for the City's operation of its WWTP pursuant to Board Order R7-2017-0013 (included as Attachment 1), which updated the previous Board Order No. 93-076 to incorporate provisions to comply with current WDRs and to require the City to evaluate and analyze potential impacts on groundwater caused by the discharge of its treated effluent. The new WDRs require that the City and its operator take steps to identify problematic waste streams, verify the suitability of the groundwater monitoring network, and complete an analysis of nitrogen and total dissolved solids (TDS) in the effluent on the receiving waters. In addition to the requirement to perform studies on the adequacy of the groundwater monitoring wells, TDS sources, and Nitrogen, the City is required to develop and implement a Municipal Industrial Pretreatment Program (MIPP) that will add a new regulatory scheme whereby the City, through Veolia, will identify commercial and industrial businesses that have the potential to discharge effluent to the City's sewer system that require pre-treatment prior to discharge, to eliminate any pollutants from entering the sewer system and the City's WWTP. The pollutants of concern are related to TDS (i.e. high levels of salts, chloride, etc.), nitrogen, certain metals, and other pollutants, and generally are caused by certain businesses that use chemicals or perform mechanical repairs (i.e. autobody repair shops), or generate waste streams with high concentration of salts. 02 City Council Staff Report November 1, 2017—Page 3 Approval of First Amendment to the Wastewater Services Agreement(O&M) Veolia Water West Operating Services Inc. Implementing the MIPP, and avoiding the discharge of pollutants into the City's sewer system from certain commercial and industrial businesses that generate polluted wastewater, is an important objective for the RWQCB, and will help to avoid further requirements for the City to invest in significantly expensive new treatment technologies at the WWTP. Veolia has provided a proposal to develop and implement the MIPP, which includes tasks that are not covered in the current agreement to provide Sewer Services. The inclusion of the tasks required to develop and implement the MIPP necessitate an amendment to the Wastewater Services Agreement No. 6804, which is included as Attachment 2. ANALYSIS: The RWQCB reviewed and updated the City's WDRs in consultation with the City and Veolia over the last several years. Under the prior Board Order No. 93-076, the RWQCB regulated the City's discharge of treated effluent to the percolation ponds, limiting the levels of chloride, fluoride, and sulfates (the main constituents of TDS). On an annual basis, the City's WWTP was unable to meet the limits imposed by the RWQCB related to chloride, fluoride and sulfate, due to the fact that the WWTP does not have treatment technology to eliminate these elements. Similarly, the prior Board Order No. 93-076 regulated the City's discharge of treated effluent related to nitrogen levels. On an annual basis, the City's WWTP was unable to meet the limit imposed by the RWQCB related to nitrogen due to the fact that the City's WWTP does not have treatment technology to eliminate nitrogen from the effluent. The fact that the City was not meeting the limits for chloride, fluoride, sulfate, and nitrogen was not a critical issue for the following two reasons: 1. Through the City's efforts to encourage water conservation, mandated through Building Code updates and other sustainable efforts, the volume of wastewater discharged to the WWTP has significantly reduced, from 10 million gallons per day (mgd) in 1992 to 6 mgd in 2016, a 40% reduction despite the widespread development throughout the City during the last 25 years; 2. Through the City's cooperative efforts with Desert Water Agency (DWA) to reuse the City's treated effluent for recycled irrigation purposes prior to discharge to the percolation ponds, the volume of treated effluent intercepted by DWA and reused has significantly increased. The RWQCB was aware of these facts, and also recognized the important cooperative efforts of the City and DWA to reuse the City's treated effluent prior to discharge to the percolation ponds, thereby intercepting the volume of wastewater potentially impacting groundwater. The City and DWA first entered into a cooperative agreement on 03 City Council Staff Report November 1, 2017—Page 4 Approval of First Amendment to the Wastewater Services Agreement(O&M) Veolia Water West Operating Services Inc. wastewater reuse and reclamation in 1977, and over the last 40 years have continued to cooperate on water reclamation which si reflected in the following statistics: ➢ In 1988, the City treated 2.7 billion gallons of sewage, of which 345 million gallons (or 12.6%) was diverted from the City's percolation ponds to DWA for reclaimed water reuse. ➢ In 2016, the City treated 2.1 billion gallons of sewage, of which 1.6 billion gallons (or 77%) was diverted from the City's percolation ponds to DWA for reclaimed water reuse. Thus, despite the substantial development of residential and commercial properties in the last 25 years, generating increased sewage Citywide, and increasing reuse of reclaimed water by DWA, the volume of treated effluent with elevated levels of chloride, fluoride, sulfate, and nitrogen discharged to the percolation ponds, and ultimately having the potential to degrade groundwater, has been drastically reduced. Put another way, if the City was treating the maximum volume capacity of its WWTP of 10.9 mgd, without any diversion to DWA for reclaimed water reuse (100% discharged to the City's percolation ponds), Board Order No. 93-076 and the recently adopted Order R7-2017- 0013 allows for discharge of 4 billion gallons annually to the percolation ponds. However, due to water conservation and DWA's reclaimed water reuse, the actual volume of treated wastewater discharged to the percolation ponds in 2016 was limited to 490 million gallons, which is only 12% of the volume the City is otherwise authorized to discharge. In its adoption of Order R7-2017-0013, the RWQCB agreed to eliminate the individual discharge limits for chloride, fluoride, and sulfate on the condition that the City analyze the potential effects of the discharge of its effluent to groundwater. Specifically, the RWQCB has required the following: 1. Groundwater Monitoring Network Technical Report and Work Plan, 2. Nitrogen Control Strategy Technical Report, 3. Total Dissolved Solids Source Control Technical Report The findings from these reports will inform changes that may need to be made at the WWTP, either in operations, procedures or physical upgrades required to comply with new limits identified in Order R7-2017-0013. City staff and the RWQCB will work together to identify any changes in WWTP operations that are required to meet new limits based on the results of these studies. Any proposed changes to the City's operations of the WWTP will be administered through Veolia, the WWTP operator, and any modifications that impact the City's and Veolia's operations will be presented to the City Council prior to implementation. 04 City Council Staff Report November 1, 2017—Page 5 Approval of First Amendment to the Wastewater Services Agreement(O&M) Veolia Water West Operating Services Inc. Performing the needed studies requires securing services from professional firms with expertise in these fields. Veolia requested proposals from four firms who specialize in performing these tasks: Larry Walker and Associates (LWA), Hazen and Sawyer (HAS), GEI Consultants, and EnviroLogic Resources, Inc. The following outlines the proposals received by Veolia on behalf of the City: • Larry Walker and Associates (LWA); Proposal Estimate: $126,640 • Hazen and Sawyer(HAS); Proposal Estimate: $200,000 • GEI and Associates: Declined to submit proposal • EnviroLogic Resources, Inc.; Proposal Estimate: $191,775 After reviewing the proposals for scope, project understanding, technical expertise, and comparable experience, it was determined that LWA was the firm best suited to perform the required studies under Veolia's supervision. The LWA proposal was ranked based on qualifications, not cost, consistent with selection of a professional services contract. LWA's proposal included a cost for services with a total of $126,640. Section 7.5 of the Wastewater Services (O&M) Agreement between the City and Veolia allows for Veolia to subcontract professional services, subject to a 15% mark-up for administrative and overhead costs. The total cost for the professional services related to the RWQCB required studies is $145,636. Veolia's proposal is included as Attachment 3. ENVIRONMENTAL IMPACT: Section 21084 of the California Public Resources Code requires Guidelines for Implementation of the California Environmental Quality Act ("CEQA"). The Guidelines are required to include a list of classes of projects which have been determined not to q p J have a significant effect on the environment and which are exempt from the provisions 9 p of CEQA. In response to that mandate, the Secretary for Resources identified classes of projects that do not have a significant effect on the environment, and are declared to be categorically exempt from the requirement for the preparation of environmental documents. In accordance with Section 15301 "Existing Facilities," Class 1 projects consist of the operation, repair, maintenance, permitting, leasing, licensing, or minor alteration of existing public or private structures, facilities, mechanical equipment, or topographical features, involving negligible or no expansion of use beyond that existing at the time of the lead agency's determination. More specifically, Class 1(b) includes the operation, repair and maintenance of existing facilities of public-owned utilities used to provide sewerage or other public utility services. Approval of the Wastewater Services Agreement for operation and maintenance with Veolia Water West Operating Services, Inc., will authorize Veolia to perform such services required to operate and maintain the City's WWTP and sanitary sewer collection system and related facilities, and is therefore considered Categorically Exempt from CEQA. 05 City Council Staff Report November 1, 2017—Page 6 Approval of First Amendment to the Wastewater Services Agreement(O&M) Veolia Water West Operating Services Inc. FISCAL IMPACT: The current O&M Fee paid to Veolia to provide sewer services to the City is $3,429,483 for calendar year 2017. Proposed First Amendment The First Amendment will increase the annually reoccurring O&M Fee by $59,800 for providing services related to implementing the MIPP, with an additional $10,000 annual budget for reimbursement of laboratory and analytical costs. This represents an increase of $69,800 annually, or a 2% increase. The First Amendment also incorporates a one-time budget of$146,656 for reimbursable expenses associated with developing the MIPP. The total cost of the First Amendment is $216,456. Separately, the City will reimburse Veolia for its direct costs associated with completion of the various studies required by the RWQCB, not to exceed $145,636. All costs associated with the Agreement, Amendment No. 1, and the Purchase Order, are entirely funded by the Wastewater Enterprise Fund (Fund 420). Sufficient funds are available in Account No. 420-6800-43200. SUBMITTED Thomas Garcia, P.E. Marcus L. Fuller, MPA, P.E., P.L.S. City Engineer Assistant City Manager David H.

The City of Palm Springs owns a wastewater treatment plant (VW TP or Facility) that provides sewerage service to the City residents and businesses. The WWTP is operated by Veolia Water West Operating Services Inc. The City of Palms Springs and Veolia Water West Operating Services, Inc. are hereby collectively or individually referred to as Discharger. 2. The Discharger submitted an application and Report of Waste Discharge (ROWD) in June 2013 to update Waste Discharge Requirements (WDRs)for the WWTP to reflect proposed design modifications to the Facility, which are discussed in Findings 7, 8, 9 and 10. 3. Palm Springs WWTP is at the end of Vella Road, south of E. Mesquite Ave., Palm Springs, as shown on the Location and Vicinity Map, Attachment A, incorporated herein and made part of this Order by reference. The Facility is located in the southeast % of Section 19, Township 4 South, Range 5 East, San Bernardino Baseline and Meridian. The Facility is assigned the California Integrated Water Quality System (CIWQS) No. CW-247435, Waste Discharge Identification (WDID) 7A330114012 and GeoTracker Global ID number WDR100032535. 4. The discharge from the Facility is currently regulated by WDRs Order 93-076, adopted on November 17, 1993. The City of Palm Springs also owns a wastewater collection system that is regulated under State Water Resources Control Board General Order 2006-0003- DWQ, Statewide General Waste Discharge Requirements for Sanitary Sewer Systems. 5. WDRs Order 93-076 must be updated to incorporate design modifications at the Facility and implement the most current water quality laws and regulations applicable to the discharge. 6. The Facility has been regulated by the Colorado River Basin Water Board since its construction in 1960. The Colorado River Basin Water Board action, Resolution 63-3, and subsequent Resolutions and Board Orders contained effluent limitations for sulfate and chloride. This Board Order removes the effluent limits for chloride, fluoride and sulfate and introduces a regulatory approach where these analytes will be regulated as constituents of total dissolved solids (TDS). The Special Provisions of this Board Order require that the Discharger conduct an investigation to control salinity, and develop and implement a source control program for mineralized waste discharges into the collection system. After completion of the investigation, the Discharger will present conclusions and recommendations for a final TDS effluent limit in a technical report. In addition, the Special Provisions of this Order require the Discharger to conduct a nitrogen fate and transport study 08 City of Palm Springs Board Order R7-2017-0013 Wastewater Treatment Plant Waste Discharge Requirements and prepare a technical report to investigate the sources of nitrogen in the discharge and determine the relationship between the discharge and the levels of nitrogen nitrates found in the groundwater monitoring network. Wastewater Treatment Facility and Discharge 7. The Facility is currently designed to treat and discharge up to 10.9 million gallons per day (MGD) of treated domestic wastewater. Attachment B, incorporated herein and made part of this Order by reference, shows the Facility's Schematic Flow Diagram. The treatment system consists of the following processes: a. Preliminary Treatment: Preliminary treatment includes one automatic bar screen,which is followed by two aerated grit chambers operating in parallel. Large materials are removed by the bar screen. Sand and heavy inorganic particles are removed in the aerated grit chambers. Removed material is collected and disposed of at an approved solid waste management facility. b. Primary Treatment: Effluent from the aerated grit chambers enters one of three primary clarifiers operating in parallel, where solids settle to the bottom of the tank and are segregated from the effluent. Grease and oils, which float to the surface, are skimmed off and segregated from the effluent. Sludge solids and grease are then pumped to the gravity thickeners for further concentration. c. Secondary Treatment: Secondary treatment includes four trickling filters and six secondary clarifiers with both systems operating in parallel. Effluent from the primary clarifiers is combined with recycled trickling filter or secondary effluent for dilution. The combined flow is then pumped over the trickling filters where the majority of the soluble organic matter is removed through absorption and utilization by the biological organisms growing on the trickling filter media. Trickling filter effluent, along with biological organisms that periodically slough off the media, flows to the secondary clarifiers where suspended solids are removed before discharge. Solids collected at the secondary clarifiers are pumped to a gravity thickener. The solids are then transferred to anaerobic digesters for further treatment. d. Effluent Disposal: Approximately 25 percent of the final WWTP effluent is disposed of to one of six unlined evaporation/percolation ponds (totaling 23.3 acres). This Board Order regulates the discharge to the evaporation/percolation ponds. The effluent discharged to the evaporation/percolation ponds is rotated from pond to pond on a frequency that does not exceed 7 days for each pond. Following the use of an evaporation/percolation pond for disposal of treated wastewater, the Discharger performs maintenance for sludge control and soil scarification to maximize percolation and minimize evaporation, which reduces the increase in salinity of the ponded treated wastewater. The balance of the effluent from the WWTP (approximately 75 percent) is conveyed directly via a dedicated treated wastewater pipe to the Desert Water Agency (DWA), Wastewater Reclamation Plant (WRP) for tertiary treatment. The WRP operated by DWA is regulated by WDRs Order R7-2014-0008. DWA distributes tertiary-treated disinfected recycled water for use as landscape and golf course irrigation. Recycled water use has increased from approximately 2.4 mgd in 1998 to approximately 4.5 mgd in 2016. e. Solids Handling: All solids collected in the primary treatment after the grit chambers and secondary treatment processes are pumped to two gravity thickeners, which are 2 CI 9 City of Palm Springs Board Order R7-2017-0013 Wastewater Treatment Plant Waste Discharge Requirements operated in parallel. There the solids are settled to increase the total solids concentration prior to pumping to two anaerobic digesters,which are currently operated in series but may also be operated in parallel, if necessary. In the anaerobic digesters, organic solids in the sludge are reduced through the biochemical reactions of biological organisms. Methane and carbon dioxide are produced as a result of the process. The methane is disposed of in a gas flare. The digestion process is comprised of primary and secondary stages. In the primary stage the majority of the organic solids destruction takes place. In the secondary stage destruction continues and the solids are stored and concentrated. The solids are then drawn off into one of twenty-six (26) sludge drying beds where the solids are dried for several weeks. The dry solids concentration of the sludge in the drying bed can be increased from about 2.5%total solids to over 90%total solids. A belt filter press was installed in 2002 to allow for increased solids dewatering capabilities during the cooler winter months,when drying times are longer and the drying beds can reach capacity. Water that is removed from the sludge in the solids handling processes is collected and returned to the plant headworks for treatment. Dewatered solids are stored in an asphalt-lined impoundment area for eventual removal by a biosolids hauling contractor for legally permitted composting or land application. f. SCADA System: A Supervisory Control and Data Acquisition(SCADA)system provides monitoring of plant equipment and processes. The system utilizes a central computer station, as well as remote Programmable Logic Controllers(PLCs) and panel view units that allow key equipment and processes to be viewed from various locations throughout the Facility. Operational trends are monitored and all flow and pond level data are saved to a permanent archive. The system monitors equipment and sends alarms to operators if problems are detected. g. Backup Power: Back-up power is available for all treatment processes. 8. The original WWTP was constructed in 1960. A major expansion of the WWTP to its current 10.9 million MGD capacity was completed in 1983. In consultation with Veolia Water West Operating Services, Inc., the City of Palm Springs staff prepared a comprehensive Capital Improvement Plan (CIP) for the WWTP, which addressed on-going maintenance issues at the WWTP that have resulted from aged mechanical equipment. Many of the WWTP's treatment units are past their useful life and are in need of replacement. The CIP identified the need to focus on major capital projects to replace aging equipment and improve inefficient wastewater treatment processes at the WWTP over a period of 20 years. The CIP, submitted to and approved by the City Council in 2010, is estimated at $67,000,000. The CIP assessed all of the major unit processes at the City's WWTP, and recommended a 20-year program consisting of over 30 projects, some of which may be combined into single projects for better cost efficiencies. 9. Over the last eight years the City has completed rehabilitation of the two anaerobic digesters, construction of a new reclaimed water pump station, improvements to the gravity thickeners, construction of an entirely new electrical system, installation of a new backup power generator, and installation of a new WWTP perimeter security fence. 10. As part of its CIP, the Discharger advertised an estimated $24.5-million construction project to upgrade the Facility in late 2016. The project consists of a new influent junction box, a new headworks including metering structure,two mechanical screens with isolation gates, a bypass channel with isolation gates, an influent pump station equipped with four vertical solids-handling turbine pumps, two primary clarifiers, two scum pump stations, two sludge pump stations, one sludge de-gritting station, replacement weir covers for two existing 3 10 City of Palm Springs Board Order R7-2017-0013 Wastewater Treatment Plant Waste Discharge Requirements gravity thickeners, replacement of Digester No. 2 dome cover, a prefabricated electrical building, and associated piping and electrical equipment. 11. The Discharger's SMRs from November 2011 through October 2016 characterize the WWTP influent as follows: Constituent Units Average Maximum Minimum Flow MGD 5.938 6.959 5.178 200C BOD5 mg/L2 225 338 125 Total suspended solids mg/L 335 1455 61 12. The Discharger's SMRs from November 2011 through October 2016 characterize the WWTP effluent as follows: Constituent Units Average Maximum Minimum 200C BOD5 mg/L 12.3 27.9 5.1 Total suspended solids mg/L 10.7 26.7 3.4 Settleable solids ml/L <0.1 <0.1 <0.1 pH pH units 7.3 7.4 7.1 Total dissolved solids mg/L 552 700 430 Sulfate mg/L 102.6 132.2 75.9 Chloride mg/L 89.4 117.2 72.1 Fluoride mg/L 0.6 0.8 0.1 Nitrate as N mg/L 11.1 16.0 6.2 Nitrite as N mg/L 0.69 1.80 <0.15 Total Nitrogen mg/L 16.5 26.8 8.8 Hydrogeologic Conditions 13. Annual precipitation in the Palm Springs area averages about 5 inches. Annual evapotranspiration rate is about 66 inches. 14. An ephemeral stream identified as the Tahquitz Creek, a Water of the United States, is adjacent to the Facility immediately to the south of a flood control levee maintained by the Riverside County Flood Control District. 15. A series of groundwater wells supply domestic water to the City. Regional groundwater flow in the area is to the southeast. The average Total Dissolved Solids (TDS) concentration of the municipal water supply is approximately 350 mg/L. 16. The depth to groundwater at the WWTP is approximately 190 feet below ground surface. 5-day biochemical oxygen demand at 20 degrees Celsius. 2 milligrams per Liter 4 City of Palm Springs Board Order R7-2017-0013 Wastewater Treatment Plant Waste Discharge Requirements 17. The Discharger's SMRs provide groundwater monitoring data for three wells in the vicinity of the discharge. Attachment C, incorporated herein and made part of this Order by reference, shows the location of the monitoring wells. Groundwater monitoring samples are collected from the three wells on a quarterly basis. Wells 1 and 2 are located downgradient and Well 3 is upgradient of the evaporation/percolation ponds. A review of the groundwater monitoring data, contained in the table below, indicates that Nitrate, Total Nitrogen, Sulfate and Chloride, show increased concentrations in the downgradient monitoring wells. Groundwater monitoring data from November 2011 through October 2016 show the following average water quality characteristics for groundwater in the vicinity of the discharge: Constituent Units Well Well Well Downgradient Downgradient Upgradient Depth to groundwater Feet 190 196 192 TDS mg/L 632 748 616 Nitrate as N mg/L 9.1 16 7.8 Sulfate mg/L 117 145 95 Chloride mg/L 99 119 91 Fluoride mg/L 0.31 0.35 0.31 Total Nitrogen mg/L 9.9 18.4 8.5 18. There are two shallow groundwater production wells downgradient of the evaporation/percolation ponds. The wells are operated by DWA for the purpose of supplementing recycled water when demand is high. 19. The site is located in a seismically active desert region. Basin Plan, Beneficial Uses, and Regulatory Considerations 20. The Water Quality Control Plan for the Colorado River Basin (Basin Plan), which was adopted on November 17, 1993, and amended on March 7, 2017, designates beneficial uses, establishes water quality objectives, and contains implementation programs and policies to achieve those objectives for all waters addressed through the plan (including amendments adopted by the Colorado River Basin Water Board to date). Pursuant to section 13263(a)of the California Water Code(CWC),waste discharge requirements must implement the Basin Plan and take into consideration the beneficial uses to be protected, the water quality objectives reasonably required for that purpose, other waste discharges, the need to prevent nuisance, and the provisions of Water Code section 13241. 21. The discharge is within the Coachella Hydrologic Subunit, and the Basin Plan designated beneficial uses for groundwater include: a. Municipal supply(MUN), b. Industrial supply(IND), and c. Agricultural supply(AGR) 22. These WDRs implement numeric and narrative water quality objectives for ground and surface waters established by the Basin Plan. The numeric objectives for groundwater designated for municipal and domestic supply are the Maximum Contaminant Levels (MCLs), and bacteriological limits specified in section 64421 et seq. of Title 22 of the CCR. 5 12 City of Palm Springs Board Order R7-2017-0013 Wastewater Treatment Plant Waste Discharge Requirements The Basin Plan states that: a. Groundwater for use as domestic or municipal water supply (MUN) must not contain taste or odor-producing substances in concentrations that adversely affect beneficial uses as a result of human activity. b. Groundwater designated for use as domestic or municipal supply (MUN), the concentration of coliform organisms shall not exceed the limits specified in Section 64426.1 of Title 22 of the CCR. 23. The Basin Plan, Chapter 3 Water Quality Objectives, Section IV Groundwater Objectives, states that the goal of the Colorado River Basin Water Board is to maintain the existing water quality of all non-degraded ground water basins. Generally, ground water that is pumped returns to the basin after use with an increase in mineral concentrations such as TDS, nitrate etc., that are picked up by water during its use. Under these circumstances, the Colorado River Basin Water Board's objective is to minimize the quantities of contaminants reaching any ground water basin. This could be achieved by establishing management practices for major discharges to land. The Effluent Limitations and Special Provisions of this Order require the Discharger to develop management practices that effectively minimize the quantities of contaminants reaching the groundwater in the area of the evaporation/percolation ponds. 24. It is the policy of the State of California that every human being has the right to safe, clean, affordable, and accessible water adequate for human consumption, cooking, and sanitary purposes. This Order promotes that policy by requiring discharges to meet maximum contaminant levels designed to protect human health and ensure that water is safe for domestic use. 25. Section 13267 of the CWC authorizes the Colorado River Basin Water Board to require technical and monitoring reports. The Monitoring and Reporting Program (MRP) establishes monitoring and reporting requirements to implement state requirements and demonstrate compliance with the Order. The State Water Board's electronic database, GeoTracker Information Systems facilitates the submittal and review of facility correspondence, Discharger requests and monitoring and reporting data. 26. This Order establishes WDRs pursuant to Division 7, Chapter 4, Article 4, of the CWC (for discharges that are not subject to regulation under section 402 of the Clean Water Act (33 U.S.C. Section 1342). 27. Pursuant to CWC section 13263(g), the discharge of waste is a privilege, not a right, and adoption of this Order does not create a vested right to continue the discharge. 28. The discharge as authorized by this Order, and treatment and storage facilities associated with discharges of treated municipal wastewater, except for discharges of residual sludge and solid waste, are exempt from the requirements of the Consolidated Regulations for Treatment, Storage, Processing, or Disposal of Solid Waste, as set forth in Title 27, CCR, Division 2, Subdivision 1 (Title 27), commencing with section 20005. This exemption is based on section 20090(a) of Title 27, which states in relevant part that discharges of domestic sewage or treated effluent are exempt provided that such discharges are regulated by WDRs, or for which WDRs have been waived, and which are consistent with applicable water quality objectives, and treatment or storage facilities associated with municipal wastewater treatment plants, provided that residual sludges or solid waste from wastewater treatment facilities shall be discharged only in accordance with the applicable Title 27 6 � 3 City of Palm Springs Board Order R7-2017-0013 Wastewater Treatment Plant Waste Discharge Requirements provisions. The discharge is treated domestic wastewater. This Order regulates the discharge in a manner consistent with applicable surface and ground water quality objectives, and residual sludges or solid waste from the Facility will be managed pursuant to Title 27. All of these Title 27 exemptions have been met. 29. This Order regulates the discharge of wastes to the onsite evaporation/percolation ponds and allows the Discharger to distribute secondary treated wastewater to DWA for additional treatment and eventual reuse. The storage and conveyance facilities associated with the distribution of secondary treated wastewater to DWA are exempt from the requirements of Title 27, based on section 20090(h). The Discharger's compliance with this Order results in meeting the applicable Title 27 provisions. 30. State policy promotes the use of recycled water to the maximum extent in order to supplement existing surface and ground water supplies to help meet water needs (CWC sections 13510-13512). One of the primary conditions on the use of recycled water is protection of public health (CWC sections 13521, 13522, 13550(a)(3)). 31. The portion of the discharge authorized by this Order that is conveyed to DWA for treatment and reclamation is consistent with the State Water Board's Recycled Water Policy. 32. Section 403.8(a) of Part 40 of the Federal Code of Regulations requires any publicly owned treatment works (POTW) with a total design flow greater than five (5.0) MGD to develop a pretreatment program if it receives pollutants from industrial users that pass through or interfere with POTW operation or if it has industrial users subject to federal categorical Pretreatment Standards. 33. Section 2233 of Title 23 of the CCR requires a pretreatment condition to be included in non-NPDES WDRs for all POTWs. The Discharger's ROWD does not identify industrial discharges into its collection system. The Discharger will be required to provide a routine assessment of its industrial dischargers in the annual Self-Monitoring Reports (SMRs) to determine whether the Discharger is a pretreatment program becomes necessary. State Anti-Degradation Policy 34. State Water Board Resolution 68-16, Policy with Respect to Maintaining High Quality Waters of the State, (Resolution 68-16) states: "Whenever the existing quality of water is better than the quality established in policies as of the date on which such policies become effective, such existing high quality will be maintained until it has been demonstrated to the State that any change will be consistent with maximum benefit to the people of the State, will not unreasonably affect present and anticipated beneficial use of such water and will not result in water quality less than that prescribed in the policies." If an activity may result in degradation to high quality waters, Resolution 68-16 further states: "Any activity which produces or may produce a waste or increased volume or concentration of waste and which discharges or proposes to discharge to existing high quality waters will be required to meet waste discharge requirements which will result in the best practicable treatment or control (BPTC) of the discharge necessary to assure that (a) a pollution or 7 14 City of Palm Springs Board Order R7-2017-0013 Wastewater Treatment Plant Waste Discharge Requirements nuisance will not occur and (b)the highest water quality consistent with maximum benefit to the people of the State will be maintained." 35. The Colorado River Basin Water Board has determined that some degradation of groundwater from the discharge to the evaporation/percolation ponds is consistent with Resolution 68-16, provided that the degradation: a. Is confined to a reasonable area; b. Is minimized by means of full implementation, regular maintenance, and optimal operation of BPTC measures; c. Is limited to waste constituents typically encountered in domestic wastewater; and d. Does not result in the loss of any beneficial use as prescribed in the applicable basin plan, or violation of any water quality objective. 36. Constituents in the WWTP effluent that have the potential to degrade groundwater include nitrogen, coliforms(pathogen-indicator organisms), TDS, and chloride and sulfate. Each of these constituents is discussed below: a. Nitrogen. The Discharger's SMRs from November 2011 through October 2016 show a range of 8.8 to 26.8 mg/L with an average 16.5 mg/L for total nitrogen in the effluent. Upgradient monitoring well MW3 shows nitrate as nitrogen concentrations averaging 7.8 mg/L and total nitrogen averaging 8.5 mg/L. Downgradient monitoring wells show nitrate as nitrogen concentrations averaging 9.1 mg/L (total nitrogen averaging 9.9 mg/L) in well MW1 and 16.0 mg/L (total nitrogen averaging 18.4) in well MW2. Well MW2 nitrate data indicate that the discharge of treated wastewater may be impacting groundwater at a rate or in concentrations causing groundwater to exceed the Primary MCL prescribed in Title 22, CCR section 64431. Using recycled water for golf course and landscape irrigation has mitigated the rate of increase and extent of the elevated nitrogen concentrations in groundwater in the area of the evaporation/percolation ponds. The Discharger currently conveys approximately 75 percent of the secondary treated wastewater to DWA for further treatment and distribution as recycled water. Additionally, DWA has installed two shallow groundwater wells downgradient of the evaporation/percolation ponds to supplement reclaim water supplies. Groundwater extraction from these two wells has further mitigated the amount of nitrogen in the aquifer. Nevertheless, monitoring data of the groundwater wells in the vicinity of the WWTP indicate that the effluent may be causing or contributing to nitrogen/nitrate impairment in the groundwater in the area of the evaporation/percolation ponds. Even with reductions in nitrogen loading due to increased water recycling, continuation of the existing treatment and evaporation/percolation pond disposal practices may pose a threat to the beneficial use of groundwater. The Colorado River Basin Water Board recognizes that immediate compliance with groundwater objectives for nitrogen may not be achievable due to historic land use practices. This Order introduces a groundwater limitation for nitrogen. Special Provisions section EA of this Order also requires that the Discharger conduct a comprehensive investigation of the sources of nitrogen and the fate of transport in the groundwater The Discharger is also required to evaluate the feasibility of achieving a 10 mg/L total nitrogen effluent limit. The results of this investigation may require the Discharger to: (1) develop and implement a nitrogen source control program, (2) enhanced management practices, and/or (3) install advanced treatment systems to reduce or eliminate nitrogen discharges to groundwater. ' 5 8 i City of Palm Springs Board Order R7-2017-0013 Wastewater Treatment Plant Waste Discharge Requirements b. Coliforms. Secondary treatment reduces fecal coliform densities by 90 to 99%; the remaining organisms in effluent are still 105 to 106 MPN/100 ml (U. S. Environmental Protection Agency, Design Manual, Municipal Wastewater Disinfection; October 1986). Given the depth to groundwater, which is approximately 190 feet in the vicinity of the WWTP, it is not likely that pathogen-indicator bacteria will reach groundwater in excess of that prescribed in Title 22, CCR, due to significant attenuation and removal in the soils in the vadose zone. To verify no degradation due to pathogen-indicator organisms is occurring, this Board Order adds quarterly total coliform and E. coli monitoring in the groundwater monitoring wells. c. TDS. During the period of November 2011 through October 2016, the Discharger's SMRs show that effluent from the WWTP had a TDS range of 430 to 700 mg/L with an average of 552 mg/L. Under Board Order, 93-076, TDS was measured based on the incremental addition of TDS above that of the community water supply. Domestic water supply to the community showed an average TDS concentration of about 350 mg/L from 2011 to 2015. The average TDS increase in the effluent for this facility over the domestic water supply for the same time period was about 175 mg/L. Salinity, measured as TDS of the groundwater in the vicinity of the WWTP ponds, ranges from 667 mg/L at Well 3 (upgradient) to 694 mg/L at Well 2 (downgradient). Title 22 of the CCR lists a Recommended Secondary MCL for TDS of 500 mg/L, an Upper Level of 1000 mg/L and a Short Term Level of 1500 mg/L. To minimize further degradation of the groundwater from TDS, this Order establishes restrictions on the WWTP intended to minimize TDS discharges and to prevent long-term impacts to beneficial uses. This Order introduces an interim effluent limitation for TDS based on based on the 99t' percentile of the of the WWTP effluent TDS data over the previous three years. Because the interim effluent limit exceeds the recommended secondary MCL, Special Provisions 4 of this Order also requires that the Discharger conduct a comprehensive investigation of the sources of salinity to the collection system and to develop and implement a source control program for salts and mineralized wastes. The results of this investigation will be used develop a final TDS effluent limit. d. Chloride and Sulfate. The Discharger's monitoring data and June 26, 2013 ROWD show an increase in chloride and sulfate concentrations in the effluent has occurred over the past 20 years. Recent effluent monitoring for chloride and sulfate show a maximum concentration of 117 and 132 mg/L, respectively. Chloride and sulfate are present in the water supply. The concentration of these inorganic constituent increases from contributions of municipal wastewater and water softening brines. One of the causes for the increased concentrations has likely been water conservation measures in the community that have significantly reduced influent flow to the WWTP. The quantity of wastewater treated has declined from about 8.8 million gallons per day (MGD) in 1993 to about 5.9 MGD in 2016. Board Order 93-076 contained effluent limitations of 70 mg/L for chloride and 90 and mg/L for sulfate. However, Title 22 of the CCR lists a Recommended Secondary MCL for both chloride and sulfate of 250 mg/L, an Upper Level of 500 mg/L and a Short Term Level of 600 mg/L. This Order replaces the individual effluent limitations for chloride and sulfate with an interim TDS effluent limit. The TDS source control study and program, described above, will be used to develop a final TDS effluent limit consistent with water quality and public health goals. The TDS effluent limit is expected to provide the necessary protection to groundwater beneficial use, while giving the Discharger the flexibility to continue and expand water conservation efforts. 9 City of Palm Springs Board Order R7-2017-0013 Wastewater Treatment Plant Waste Discharge Requirements 37. The discharge of wastewater from the WWTP, as permitted herein, reflects BPTC. The controls assure the discharge does not create a condition of pollution or nuisance, and that the highest water quality consistent with maximum benefit to the people of the State will be maintained which is consistent with the anti-degradation provisions of Resolution 9 68-16. The WWTP incorporates: a. Technology for secondary treated domestic wastewater; b. Solids handling facilities; c. An operation and maintenance manual; d. A City ordinance that is comprised of a comprehensive set of rules and regulations governing the design, construction, maintenance and use of public and private sewer facilities within City jurisdictional limits; e. A network of groundwater monitoring wells; f. Staffing to assure proper operation and maintenance; and g. A standby emergency power generator of sufficient size to operate the treatment plant and ancillary equipment during periods of loss of commercial power. Storm Water 38. Federal regulations for storm water discharges were promulgated by the U.S. Environmental Protection Agency on November 16, 1990, (40 CFR Parts 122, 123, and 124)to implement the Clean Water Act's storm water program set forth in Clean Water Act section 402(p) (33 U.S.C. section 1342(p).). In relevant part, the regulations require specific categories of facilities that discharge storm water associated with industrial activity to"waters of the United States" to obtain NPDES permits and to require control of such pollutant discharges using Best Available Technology Economically Achievable(BAT)and Best Conventional Pollutant Control Technology(BCT)to prevent and reduce pollutants and any more stringent controls necessary to meet water quality standards. 39. The State Water Board adopted Water Quality Order 2014-0057-DWQ (NPDES No. CAS000001), General Permit for Storm Water Discharges Associated with Industrial Activities (Industrial General Permit) on July 1, 2015. Facilities used in the storage, treatment, recycling, and reclamation of municipal or domestic sewage, including land dedicated to the disposal of sewage sludge, that are within the confines of the facility, with a design flow of one million gallons per day or more, or required to have an approved pretreatment program under 40 CFR Part 403, are required to enroll under the Industrial General Permit unless there is no discharge of industrial storm water to waters of the U. S.. There are no storm water discharges from the WWTP to waters of the U. S. because all storm water generated at the facility is directed to the evaporation/percolation ponds, and does not leave the boundaries of the WWTP. Therefore, the Discharger is not required to enroll under the Industrial General Permit. CEQA and Public Participation 40. In accordance with the California Environmental Quality Act (CEQA) (California Public Resources Code Section 21000 et seq.) and implementing Guidelines (California Code of Regulations, Title 14, Section 15000 et seq.), The City of Palm Springs(City), acting as the Lead Agency, prepared a Mitigated Negative Declaration(MND)for the City of Palm Springs Wastewater Treatment Plant Headworks and Clarifier Upgrade Project(SCH2014041060). 10 47 City of Palm Springs Board Order R7-2017-0013 Wastewater Treatment Plant Waste Discharge Requirements The draft MND was circulated for a mandatory 30-day public commenting period. Based on the MND, the City determined that although the proposed project could have a significant effect on the environment, the City explained in the MND that it would avoid the effects or mitigate the effects to a point where no significant effect on the environment would occur. On June 18, 2014, the City approved the MND and on June 25, 2014, filed a Notice of Determination (NOD)with the Clerk of the Board, County of Riverside. The Colorado River Basin Water Board is a responsible agency under CEQA (Public Resources Code, § 21167.3). The Colorado River Basin Water Board considered the findings of the MND and concludes that compliance with these waste discharge requirements will prevent any significant adverse impacts to water quality. 41. The Colorado River Basin Water Board has notified the Discharger and all known interested agencies and persons of its intent to draft WDRs for this discharge, and has provided them with an opportunity for a public meeting and an opportunity to submit comments. 42.

It is recommended that the City of Palm Springs (City) develop a city-wide industrial pretreatment program that follows the EPA model sewer use ordinance and pretreatment program guidelines. This will provide a proven program that is both defensible in the community and court system, in the event that the City is required to take legal action against industrial user that discharges to the wastewater collection system. The following is a breakdown of the development process based on the core components of the EPA recommended industrial pretreatment programs (source control program). The core components are required to make the program effective. A Fats, Oils, and Grease (FOG) program has already been developed and implemented by the City and will be combined with this program to create a comprehensive Industrial Pretreatment program. I. Core Program Components: A. User Survey The User Survey consists of several different searches to identify those businesses that have the potential to impact the treatment plant or the sewer collection system. These surveys usually include a review of the following: • City Utility Billing Records for Water Consumption (Can the City get this info from DWA?) • New Business Listing by Establishment Date on City web site • Internet Search • Street Surveys • Locate and Mail Survey of Identified Potential Industrial Users • Review Survey's and Conduct Initial Inspection • Development of Final User List 44 1 Industrial Pretreatment Program Development Proposal September 26, 2017 The end product is a set of potential commercial and industrial user lists, identifying those businesses that may be required to comply with the proposed industrial pretreatment program rules. Further details are provided in the attached Scope of Project Deliverables document. B. Existing Regulations, Sewer Service Conditions This component of the development process is to establish the existing conditions and to evaluate existing sewer use ordinance and treatment plant conditions to determine if they are adequate or if there is a need to modify the sewer use ordinance or develop a new document. This usually includes the following: • Treatment Plant Influent/Effluent/Sludge Pollutant Loadings • Treatment Plant Flows and Sludge Production Rates • Treatment Plant WDR Permits Review • Review of Existing Industrial User Permits, Agreements, or Contracts (DWA) • Review of the Existing Sewer Use Ordinance • Determine Known/Historical Problems in the Collection System and Treatment Plant due to Industrial User Contribution The review of the existing city ordinances and intergovernmental agreements will be conducted concurrently during this phase of the process. C. Local Limits Development This component establishes the industrial discharge limits for all pollutants of concern, such as, oil & grease, inorganic pollutants, heavy metals, and toxic organic compounds. The final result of this activity is the documentation of the local limits, creating an explanation of the decisions and the basis for each pollutant for which local limits are developed. These local limits will be adopted into the sewer use ordinance by the City Council. The EPA recommended methodology will be used to develop these technically based local limits. The EPA has established fifteen national Pollutants of Concern (POC) typically discharged to wastewater treatment plants, and has mandated the EPA Approved Pretreatment Programs to establish technically based local limits for these pollutants. Pollutants regulated by the sludge disposal rules for the disposal practices used by the City are also candidates as pollutants of concern. Priority pollutants that have been detected at concentrations of 0.1 milligrams per liter (mg/L), or more, in the wastewater treatment plant influent during previous sampling events should also be included as pollutants of concern. D. Sewer Use Ordinance Review of the existing sewer use ordinance is necessary as the existing sewer use ordinance may not be comprehensive enough for the protection of workers, operation of the wastewater collection system, compliant with the latest EPA regulations, and treatment plant for effective regulation of industrial discharges. Veolia has developed and submitted a draft Sewer Use Ordinance for the City's review. This draft will be updated as we move through the Industrial Pretreatment Program development process and establish Technically Based Local Limits, etc. This process includes formatting to the typical ordinance format used by the City; working through the ordinance conditions and terms, with the City Attorney; providing all required referencing within the ordinance; and responding to any comments from the City Council, staff, and general public. 45 2 Industrial Pretreatment Program Development Proposal September 26, 2017 E. Enforcement Response Plan The Enforcement Response Plan is a written plan that is used by the City to conduct enforcement actions against industrial users not complying with the terms and conditions of the sewer use ordinance and industrial pretreatment program, and discharge permits issued to the users. The purpose of this document is to provide uniform and consistent enforcement of the sewer use codes. This becomes critical in the event the City must take a legal action against an industrial user. The proposed Enforcement Response Plan will be based on the EPA Guidance for the development of Enforcement Response Plans. This plan will also contain samples of enforcement documents, such as, Notices of Violation, Administrative Orders, Administrative Fee/Fine Assessments, Service Termination Orders, and Consent Orders. F. Implementation Management Procedures The Implementation Management Procedures constitute the Standard Operating Procedures used to implement the Industrial Pretreatment Program. These procedures identify the persons involved in the activity, the authority to conduct the activity, the actions to be taken, and references for further support of the activity. Included in these procedures are samples of all forms used in the program. The purpose of implementation management procedures is to provide the City with sufficient guidance to carry out the requirements of the sewer use ordinance in a uniform and consistent manner to all users of the city wastewater collection system. The EPA does not provide guidance on the development of these protocols, but has provided guidance through multiple guidance manuals for the many different activities under the industrial pretreatment rules. Veolia has developed these implementation management procedures over the past 13 years and has implemented them at many Veolia projects, in many different states, and different EPA Regions. These implementation management procedures have been reviewed and audited by the EPA and State regulatory agencies and found to be in compliance with recommendations for these procedures. These procedures are not generic and must be modified to meet the local conditions and the local sewer use ordinances, enforcement response plan, including appropriate references to local ordinance provisions and state regulations. G. Issue Industrial User Permits With any changes to the sewer use ordinance, the City will be required to issue discharge permits to the existing industrial users and new permits to those identified in the Industrial Waste Survey development process. Veolia recommends the use of Industrial User permits recommended by the EPA, following the EPA Guidance for industrial wastewater discharge permits. Sample permits will be included in the implementation management procedures. H. Industrial Pretreatment Program Submission to CRWQCB WDR Permit Order No. 93-076 issued November 17, 1993 requires the investigation for the need for an Industrial Pretreatment Program following the location and characterization of pollutants from identified industrial users. This requires the preparation of program documents and submission to the California Regional Water Quality Control Board for approval. 46 3 Industrial Pretreatment Program Development Proposal September 26, 2017 I. Public Outreach and Education Send a general sewer use information mailer to 26,000 sewer users ("This is Not a Trash Can"). Purchase tri-fold brochures that have the same type of information to set on the engineering counter, information area at entrance to City Hall, include in the sewer connection permit packet, participation in community activities, etc. II. O&M Costs to Implement this Program A. Industrial Pretreatment Program The initial implementation of the program is very time consuming. The components of the industrial pretreatment program need to be implemented immediately for the program to be developed properly to meet the goals and objectives. Industries identified as significant industrial users (SIU) need to be permitted first under the program. Each SIU will require onsite training on how to conduct and report self-monitoring. The pretreatment coordinator or program manager needs to be trained on how to conduct SIU inspections and sampling on behalf of the City and how to evaluate self-monitoring reports for compliance. The City also has responsibilities in the implementation of the program, most of which includes enforcement response procedures. The resources to meet the demands of the enforcement actions are un-predictable. This is assuming that there are only one or two SIUs that require discharge permits and routine inspection and sample monitoring. If the number of SIUs is low, a local commercial laboratory is often used to collect and analyze samples; therefore the labor demands for City monitoring program will be reduced. In addition, the City would have language in the new sewer use ordinance, allowing them to assess pretreatment cost recovery fees. These fees are typically assessed to recover the costs associated with the preparation of SIU discharge permits, city inspections, city sampling, and other activities associated with the implementation of the industrial pretreatment program. This is a common practice and often expected by industrial users that have production facilities located in different cities across the nation. Therefore, it is anticipated that the City of Palm Springs will have the ability to recover the routine operational costs associated with the industrial pretreatment program. The Veolia proposal fee structure is based upon a Time & Material (T&M) Fee for the development of the Palm Springs industrial pretreatment program. Attachment B provides a breakout of the hourly rate for each person involved with the program development as well as estimated non-labor costs. Labor and non-labor costs shall include a 15% overhead on the cost incurred. Veolia's price to provide all of the services described is broken out as follows: • Labor costs (cost + 15%) for Industrial Pretreatment Program development is estimated to be approximately $49,306 • Capital costs (cost + 15%) for required equipment is estimated to be approximately $96,350. 4? 4 Industrial Pretreatment Program Development Proposal September 26, 2017 • Total IPP Development cost is estimated to be $145,656. B. Typical Pretreatment Program Operational Costs Once the pretreatment program begins to regulate more than two significant industrial users, a full time pretreatment coordinator is usually required. A single person, with occasional assistance from a commercial laboratory or treatment plant operators, can usually regulate as many as ten (10) significant industrial users. Programs of this size usually run an annual budget of $80,000 to $110,000 including salary, but not including analytical costs, which are usually passed on to the industrial users in the cost recovery program. City of Palm Springs Industrial Pretreatment Program Operational Costs - Approximately $69,800 Annually The implementation of the industrial pretreatment program for 2017 is based on using one half- time person to coordinate and implement the program. This is proposed as long as there are fewer than 10 IU's in the program. However, the pretreatment coordinator is proposed to be a full-time positon.

The Special Provisions described in Section E.of the Order include: • E.1 Groundwater Monitoring Network Technical Report and Work Plan • E.3 Nitrogen Control Strategy Technical Report: Fate and Transport Investigation, and Effluent Limit Feasibility Study • E.4 TDS Source Control Program Technical Report 1.0 Scope of Work Task 1. Groundwater Monitoring Network Technical Report and Work Plan The WDR is requiring that the City prepare a Technical Report on the adequacy of the existing groundwater monitoring network. LWA will develop a Technical Report that includes the following: 1. Description of the current condition of the groundwater monitoring network and evaluation for whether this network adequately monitors the effects of the discharge from the disposal ponds on groundwater; 2. Analysis of the groundwater data collected from the existing groundwater monitoring wells. This analysis shall include maps showing the direction of flow and identification of upgradient and downgradient monitoring wells;and 3. Statistical analysis for constituents of concern (TDS and its major ions)for the upgradient and downgradient wells, based on the groundwater data collected to date. Page 11 Special Provisions Assistance Scope of Work September,2017 5 7 Proposal Provided to: �,- Larry Walker Associates, Inc. oil City of Palm Springs -),� �f CAUFORNIA Like no place else:' LWA will evaluate the current conditions and adequacy of the groundwater monitoring network according to the following subtasks. Review of Existing Information LWA will review the data and conclusions from existing monitoring data,technical reports, and previous investigations which provide information pertaining to the current groundwater monitoring network. LWA will coordinate with Veolia and City staff to obtain any additional information necessary to complete the evaluation beyond what is provided in existing technical reports. Anticipated additional information may include but is not limited to well logs,well construction information, and effluent or groundwater well monitoring data. Due to the limited number of wells in the monitoring network, LWA will also gather and review any nearby groundwater data maintained in public databases by the State Water Quality Control Board, United States Geological Survey,and the California Department of Water Resources. Groundwater Monitoring Network Evaluation Based on information reviewed above, LWA will evaluate the current groundwater monitoring network with a focus on determining: • Direction of groundwater flow and identification of upgradient and downgradient monitoring wells'; • Groundwater quality and groundwater quality trends in downgradient and upgradient monitoring wells • Effectiveness and reliability of existing compliance wells to represent downgradient groundwater quality; • Effectiveness and reliability of existing background wells to represent upgradient water quality; and • Overall adequacy of the existing monitoring network and recommendations. . Groundwater Monitoring Network Summary Technical Report LWA will prepare a Groundwater Monitoring Network Summary Technical Report based on data obtained and evaluated. The Report will specifically address the items noted in the WDR and provide recommendations regarding any changes or additions to the monitoring networks, if necessary. If the Technical Report indicates that repairs or additional monitoring wells are necessary, LWA will prepare a work plan to submit to the Regional Water Board.This work plan will include a description of proposed changes to the monitoring network(such as monitoring locations,frequency, sampling protocols, or quality assurance/quality control)and a time schedule for these changes that is as short as practicable based on the issues identified in the Technical Report. Task 1 Deliverables: 1 The degree of accuracy when analyzing groundwater flow direction and identifying upgradient and downgradient wells is contingent upon the amount of groundwater information locally available. /. ,.

City of Palm Springs ' CALIFORNIAAiOfyR take no pace else' • Draft and Final Groundwater Monitoring Network Technical Report • Draft and Final Work Plan for Monitoring Network Changes, if necessary Task 1 Schedule: Deliverable Date Draft Technical Report February 21, 2018 Final Technical Report March 21,2018 Draft Work Plan (if necessary) 3 months from EO approval of Technical Report Final Work Plan (if necessary) 4 months from EO approval of Technical Report The schedule and budget does not include monitoring well design and construction and testing of the new wells. Should new wells be necessary, a monitoring well installation workplan and well construction would be conducted in conjunction with another firm. It is estimated that well completion and monitoring to determine that wells are representative of groundwater quality would take approximately 2 years from EO approval of the Final Work Plan for Monitoring Network Changes. Task 2. Nitrogen Control Strategy Technical Report The WDR is requiring that after determining the groundwater monitoring network is sufficient,the City shall prepare a Technical Report that includes a work plan and time schedule to evaluate the impact of the discharge on nitrogen levels in groundwater. LWA will prepare this Technical Report to include the following: 1. Determination of whether wastewater discharged to the evaporation/percolation ponds is causing nitrogen impairment to groundwater; 2. Determination of the feasibility of achieving a 10 mg/L total nitrogen effluent limit;and 3. Plan to ensure the limit does not cause exceedance of the nitrogen receiving water limitation. The Technical Report will be comprised of two main pieces: a fate and transport investigation and an effluent feasibility study. Fate and Transport For the fate and transport investigation, LWA will include: • An evaluation of nitrogen removal technology; • Characterization for total nitrogen and nitrates of the wastewater discharged to the evaporation/percolation ponds and in the receiving groundwater; and • Evaluation of the impact of the wastewater discharged on the groundwater in the vicinity of the percolation ponds with respect to nitrogen concentrations.A spreadsheet mixing model will be used to estimate the distance from the pond at which the groundwater limit can be met. Impacts will be evaluated with respect to concentration and with respect to total load of nitrogen discharged. This will help to account for reduced loads discharged to the Page 13 Special Provisions Assistance Scope of Work September 2017 El Proposal Provided to: Larry Walker Associates, Inc. ' City of Palm SpringsI� 10. LALIFORNiA - Like M Ooce else:' percolation pond when effluent is diverted to Desert Water Agency. Feasibility For the effluent feasibility study, LWA will include discussion of the practicability of achieving a 10 mg/L total nitrogen effluent limit, including projected costs and potential sewer rate increases. LWA will evaluate alternative methods of treatment,optimization of existing treatment processes and other management strategies(e.g., using high nitrogen water for irrigation)that are available and may be implemented to achieve a 10 mg/L total nitrogen effluent limit.The alternative analysis will include the costs of the alternatives, expressed in dollars per ton,of nitrogen removed from the discharge. Technical Report LWA will use the information prepared in the Fate and Transport and Feasibility sections to compile a Technical Report.This Technical Report will include the findings, recommendations and conclusions as well as a work plan and schedule for facility or operational improvements to achieve needed nitrogen reductions and comply with the effluent and groundwater quality limits.

Should additional monitoring be necessary,the schedule may need to be revised. In addition,the budget and schedule assume that the WDR is revised as requested and that the requirement to provide a "description of soil conditions in the vadose zone,through the saturated zone, and the effect that the soils have on the fate and transport of nitrogen species(converting nitrogen species of nitrate/nitrite,etc.)" is removed from this study's requirements. Task 3. TDS Source Control Program Technical Report Page 14 Special Provisions Assistance Scope of Work September 2017 60 Proposal Provided to: Larry Walker Associates, Inc. City of Palm Springs CAUFORNIA Like no piece else" The WDR is requiring that the City prepare a Technical Report that includes a work plan and time schedule to develop and implement a TDS Source Control Program. LWA will work with Veolia and City staff to review existing information and determine what additional information and data is needed to quantify salinity sources. Specifically, LWA will work with staff to collect data regarding commercial and industrial facilities in Palm Springs and review available data for these sources. In addition, LWA will review any available data regarding residential use of self-regenerating water softeners and water supply data particularly with respect to water supply hardness and TDS levels. This information can be used to estimate contributions to influent TDS from different sources. LWA will use this information to identify the most effective source control strategies for reducing TDS discharges to the treatment plant. LWA will prepare the Technical Report required by the WDR using this information to address the outlined objectives of the Source Control Program: • Evaluation of source control and methods to reduce TDS concentrations in the discharge to the evaporation/percolation ponds; and • Identification of the major sources of salinity into the WWTP collection system (e.g. domestic, commercial, industrial, water softener regeneration brine). Per the WDR, LWA will include the following strategies in the work plan provided in Technical Report: • Description of the municipal entity and facilities, including local ordinances, and rules and regulations that address the topic of controlling salinity in wastewater; • Identification and description of entities responsible for controlling each source, if available; • TDS concentration and waste load (lbs/day)for each of the identified sources and an overall TDS mass balance for the influent into the WWTP; • Description of wastewater treatment strategies available and employed at the facility to remove identified pollutants; and • Characterization of TDS in the wastewater discharged to the evaporation/percolation ponds and in the receiving groundwater.

We received the attached errata sheet approved by the Regional Board. We reviewed our proposal dated August 28, 2017 as it relates to the errata and are providing you with a revised fee estimate and the attached revised schedule associated with these changes. For your convenience, we have also attached a copy of the August 28 2017 proposal. The Regional Board errata are significant to the City of Palm Springs. However, the impacts to the proposed Hazen scope relate to schedule extensions, streamlining the background documentation for the nutrient removal evaluation, and removing the public outreach program. This letter specifically responds to the streamlining of the scope of work by removing subtasks a,b, d and f from Task 3.2. In addition, this letter removes the public outreach approach scope from Task 4.4. The attached revised schedule and the revised fee table below will replace the originals included in the proposal dated August 28, 2017. No. Task Original Revised Fee 1 Study Plan and Communication $50,0804Fee 8,000 2 Groundwater Monitoring Network $42,800 $42,800 3 Nitrogen Control Study $55,680 $48,480 4 TDS Source Control Program $49,440 $46,720 Subtotal Labor $198,000 $186,000 5 Travel and Misc Expenses $14,000 $14,000 Total Fee $212,000 $200,000 66 As previously noted Hazen is a local firm and committed to be responsive to your needs. Please contact either of us with any questions. Very Truly Yours, 4 tat.
