Subject: Proposal for Professional Engineering Services for the AquaSel Demonstration Project

Dear Mr. Jorgensen:

We understand that Eastern Municipal Water District (EMWD) is planning to construct, operate, and evaluate a demonstration scale brine reduction technology process using proprietary equipment and processes obtained from GE Water & Process Technologies (GE). The specific process is referred to as the AquaSel which was previously demonstrated with promising results on a pilot scale at the Perris I and Menifee Desalters site. The purpose of the AquaSel Demonstration project is to advance EMWD’s past effort and develop an understanding of the economics of the process, regulatory compliance issues, and assess process deficiencies identified during the demonstration testing phase.

As we have demonstrated in our proposal the CH2M Project team has comprehensive knowledge of the existing facilities, the AquaSel process, project needs and goals. We are committed and available to support your professional engineering needs for this project. To accomplish your goals and ensure timely, cost effective delivery of this project, the CH2M Project team provides:

A strong team with familiarity and knowledge of your facilities and with experience working with GE.

1 Project Understanding and Approach As water scarcity continues to increase in many regions throughout the U.S., there is a growing interest in desalination of impaired water sources. Reverse osmosis (RO), a reliable and widely used technology for desalting brackish groundwater in the United States, generates a reject stream (concentrate) which needs to be disposed properly. Even for inland regions of Southern California where regional concentrate pipelines to the ocean exist, concentrate disposal costs continue to increase as long‐term operational issues arise with pipeline scaling, maintenance, and decreased line capacity. Eastern Municipal Water District (EMWD) operates groundwater desalination facilities in southern California capable of delivering 6,000 acre‐feet per year (AFY) of product water while currently generating 17,000 tons of salt that is disposed of along with 2.3 million gallons per day (mgd) of RO concentrate through the Inland Empire Brine Line to the ocean 70‐miles away. Desalination is a critical component of EMWD’s sustainability plan as conservation becomes more arduous, and recycling more cost effective. EMWD plans to expand desalination capacity to produce 15,000 AFY of potable supply, which would increase RO concentrate production proportionally. Exhibit 1‐1 shows EMWD's service area, and Exhibit 1‐2 shows the location of the existing Menifee and Perris I desalters.

Exhibit 1‐2. Facilities Location Map

For the past decade EMWD has evaluated different technologies to recover additional drinking water from the RO concentrate and reduce the volume that is disposed of to the ocean. Desalination and Water Purification Research and Development Program Report No. 149, Evaluation and Selection of Available Processes for a Zero‐Liquid Discharge System for Perris, California, Ground Water Basin, (United States Department of Interior , Bureau of Reclamation, April 2008) was prepared in response to disposal issues. This work involved evaluating several emerging technologies to concentrate RO concentrate further and, if possible, to totally eliminate the need to dispose of any liquid stream. Simultaneously, EMWD also pilot tested a lime softening/RO treatment train, and also evaluated emerging technologies such as slurry precipitation and recycle RO (SPARRO, seeded RO), SAL‐PROCTM, membrane distillation, and forward osmosis. At the time this evaluation was completed, these processes were found to be in the early stages of development and have not been tested at a reasonable scale.

The pilot scale study of the lime softening /RO process was able to reduce the reject stream from 30 percent, to 6 to9 percent. However, the softening process required significant amounts of lime and generates substantial quantities of sludge, which requires disposal, and ultimately did not reduce the brine stream volume to a manageable level.

3

In 2014 and 2015, EMWD carried out a pilot scale evaluation of the AquaSel Technology developed by GE Water and Process Technologies (GE). This process (Exhibit 1‐3) combines electrodialysis reversal (EDR), used to partially desalinate the concentrate, with acidification and a solids contact reactor to precipitate and remove calcium sulfate from the EDR brine stream, while recovering a high percentage of the feed water as product. The goal of the pilot study was to treat 8 gallons per minute (gpm) of concentrate from the Menifee Desalter with the AquaSel pilot and determine what recovery AquaSel could achieve and the quality of product water generated by the process. Additional goals included establishing operating costs, power consumption, and amount of solids produced per gallon of RO concentrated treated.

Exhibit 1‐3. Schematic of GE's AquaSel Technology (Successfully pilot tested at EMWD in 2015)

1.1 Summary of AquaSel Pilot Testing (2015) The pilot system was set up close to EMWD's Menifee desalter. Exhibits 1‐4 and 1‐5 present photographs of the equipment at the site. The pilot plant was operated from November, 2014 through July 2015, achieving over 1,700 hours of run time. The results demonstrated that the AquaSel process was able to treat the Menifee RO concentrate without pretreatment and produce a product water with an average total dissolved solids (TDS) of approximately 2,000 milligrams per liter (mg/L). The process was able to operate at a recovery of 80‐percent, which would result in an overall recovery of 95‐percent, when combined with the desalter recovery of 75‐percent. If applied at full‐scale, the process would currently reduce the volume of desalter concentrate from 2.3 mgd to about 0.5 mgd, saving EMWD about $500,000 per year in disposal costs. More savings will be recognized as EMWD expands the capacity of its desalination facilities.

Exhibit 1‐6 presents a trend of conductivity data from the AquaSel pilot testing for the period May through July, 2015. The figure shows that both the EDR feed conductivity (blue values) and concentrate conductivity (green values) were relatively stable. More importantly, the product conductivity (red values) was also relatively stable, recognizing that the elevated red data values are the result of "reversal noise" caused when polarity is reversed between the positive and negative electrodes of the

EDR stack.

Exhibit 1‐6. AquaSel conductivity data May through July 2015

During the final phase of testing between May and July, 2015, several of the project objectives were achieved, as summarized below:

1.1. The technical feasibility of the AquaSel process was clearly demonstrated by operating on Menifee desalter RO concentrate and achieving almost 1,000 hours of continuous operation (960 hours of virtually continuous operation was achieved) at one set of operating conditions defined in Exhibit 1‐7.

1.2. Stable performance of the AquaSel system was demonstrated through continuous monitoring of the EDR system pressures, EDR system voltages and amperages, and feed, product and concentrate conductivities (Exhibit 1‐6). The performance of the precipitation tank could not be fully evaluated due to a lack of analytical data. A product total dissolved solids limit of about 2,000 milligrams per liter was set, which was achieved on average.

1.3. The anticipated long term operating costs for a 2.3‐mgd system, including chemical usage, electrical power costs, membrane cleaning frequency and costs, solids production rate and disposal cost, membrane and other EDR stack component replacement costs were all determined based on data collected during the final phase of testing.

1.2 Limitations of the 2014/2015 Pilot Study, Challenges and Technical Risks with Demonstration Phase

During pilot testing, the following main challenges/limitations were encountered:

The solids production rate from the process and the solids mass balance for the system were not fully evaluated. The performance of the precipitation tank could not be fully evaluated due to a lack of analytical data. It was determined that full precipitation of gypsum was not occurring, due to an undersized precipitation reactor. This hampered the ability to achieve a good materials balance across the system.

A goal was to determine the chemical make‐up of the solids produced by the process and how it could be disposed of from a full‐scale facility treating 2.3 mgd of primary desalter concentrate. This goal was not fully achieved, again due to the performance of the precipitator. Gypsum was definitely being produced, but some calcium carbonate may also have been produced.

One key goal of the 2014/2015 work was to establish a materials balance around the precipitator reactor in order to confirm stable operation of the system over a long operating period. As mentioned, this goal was not fully achieved because of precipitator reactor under‐sizing. This resulted in a highly super‐saturated solution of calcium sulfate leaving the reactor together with excess amounts of solids in the precipitator overflow. The downstream impact of the excessive solids was very limited candle and cartridge filters life, which were used to remove solids carryover from the precipitator overflow prior to its return to the EDR brine loop. Exhibit 1‐8 shows photographs of the cartridge filters after 3‐4 days of operation, clearly indicating the large amount of solids captured by the filters. Some of the solids visible in the filters is thought to have precipitated between the precipitator and the filter due to super‐saturated levels of calcium sulfate in the precipitator overflow.

7

Exhibit 1‐8. Cartridge filters showing excess solids accumulation

A technical risk associated with the AquaSel demonstration project is failure of the precipitator reactor to perform as required. In other words, higher than desired suspended solids levels will be present in the overflow from the reactor, and/or the solution leaving the reactor will still be at a high super‐saturation level with respect to calcium sulfate (the de‐supersaturation reaction in the precipitator will not have gone to near completion). If either of the above scenarios should occur, it could cause clogging and/or precipitation within the piping and equipment; leading to operational challenges or failure.

To mitigate this technical risk, GE has modified the design of the precipitator to increase retention time, added a hydrocyclone to treat the precipitator overflow and remove a large fraction of any solids present, thereby reducing loading to downstream filters, and modified the acid cleaning system to include all the pipes and equipment downstream of the precipitator to remove precipitate, should it form.

1.3 Proposed Project Approach The successful pilot testing of the AquaSel process on Menifee desalter concentrate was discussed above. Due to its small flow (8‐gpm) and manual operation, the pilot plant was limited to evaluating the performance of the EDR portion of the AquaSel process for desalter concentrate treatment. The precipitator and downstream solids system was less than optimal. To overcome these limitations, it is proposed to install and operate an AquaSel system that reflects a full‐scale design, which requires a system having a flow rate of 100‐gpm. This will allow the following:

Full‐scale EDR stacks to be used: a 100‐gpm unit is the smallest unit that allows full‐scale EDR stacks to be used. The system would include four full‐sale EDR stacks in series to provide a 4‐hydraulic stage system as required to achieve the targeted TDS removal. The 8‐gpm pilot unit had a single small EDR stack that incorporated the 4‐hydraulic and two‐electrical stages. This resulted in limitations in terms of the hydraulic flows around the stack such as the electrode rinse streams.

8

Enhanced precipitator reactor design: a larger feed flow will allow reasonable scale‐up of the Precipitator reactor and the downstream solids removal system. Precipitator design for the 100‐gpm system will be optimized based on the pilot experience, and will include a hydrocyclone solids removal system prior to the filtration step.

1.4 Determination of Success If the 100‐gpm pilot facility testing is successful then the following will have been achieved:

Continuous operation of the AquaSel system at 80 percent recovery combined with production of a consistent product water quality.

Good performance of the precipitator reactor to result in low concentration of solids in the effluent from the reactor and a calcium sulfate saturation level that is close to 100 percent.

A good materials balance across the Precipitator that can be used to scale up the system further to the 400‐gpm module size, and that can predict accurate waste solids production rates.

Accurate assessment of operating and maintenance costs so that cost estimates for the full‐scale (2.3 mgd) or larger system can be verified.

Successful dewatering tests on the solids wasted from the Precipitator will have been performed and a technology to be utilized in the full‐scale system and its associated cost to produce dewatered solids cake that can be trucked from the site for disposal will have been identified.

Optimization of the AquaSel system, which might include producing a lower salinity product water and/or increasing the recovery to beyond 80‐percent.

The AquaSel process is already commercially available. However, the application of the process to treat EMWD's RO concentrate is unique and needs to be carefully evaluated before EMWD invests around $40 million to install a full‐scale system. Hence the proposed approach to evaluate a small pilot plant (8 gpm ‐ already complete), move to the 100‐gpm system (the current proposal), and finally to the 400‐gpm module size, for which there would be four trains in the full‐scale system. Grant funding potential for the full‐scale system is expected to be good.

2 Technical Approach The following are the six major goals of the proposed 100 gpm pilot study:

Demonstrate continuous operation of the AquaSel system at 80 percent recovery combined with production of a consistent product water quality.

Demonstrate good performance of the Precipitator reactor to result in low concentrations of solids in the effluent from the reactor and a calcium sulfate saturation level that is close to 100‐percent.

Demonstrate a good materials balance across the Precipitator that can be used to scale up the system further to the 400‐gpm module size, and that can predict accurate waste solids production rates.

Obtain an accurate assessment of operating and maintenance costs so that cost estimates for the full‐scale (2.3 mgd) or larger system can be verified.

9

Conduct dewatering tests on the solids wasted from the precipitator to establish the technology to be utilized in the full‐scale system and the associated cost to produce dewatered solids cake that can be trucked from the site for disposal.

Optimize the AquaSel system, which might include producing a lower salinity product water, if feasible from an electrical energy perspective, and increasing the recovery to beyond 80 percent.

To achieve the above goals, it is proposed to split the work into the following four main phases:

Phase 1 ‐ Design, protocol development, equipment procurement, construction and startup

Phase 2 ‐ Baseline operation at 80‐Percent Recovery

Phase 3 ‐ Optimization Operation

Phase 4 ‐ Decommissioning

Phase 1: Design, protocol development, equipment procurement, construction and startup. This phase of the project will include four major work elements, which are described in Section 3, and include engineering work associated with establishing a site at either the new Perris II Desalter or the Menifee and Perris I desalters to install the 100‐gpm AquaSel system; procuring the equipment; the design and construction of the infrastructure for demonstration facility and installation of the 100‐gpm AquaSel system by GE; development of the Testing and Operating protocol for the operating phases of the project; and the commissioning and startup of the 100‐gpm AquaSel system by GE.

Phase 2: Baseline operation at 80 percent recovery. The onsite testing will be carried out in two testing periods. The first testing period will last for 6 months. This testing period will have the purpose of confirming the results of the 8‐gpm pilot test under a single set of operating conditions, but more importantly will also focus on confirming the performance of the optimized precipitator reactor.

A preliminary assessment has been made of the number of samples that will be collected during this period. Exhibit 2‐1 shows the preliminary anticipated sampling schedule for this phase of the project. The AquaSel feed and product streams will be sampled once per week on average. Samples will be taken around the precipitator reactor three times per week in order to provide a good batch of data to confirm the materials balance and operation of the reactor. Some parameters will be monitored continuously by analyzers built into the process, but all will also be analyzed in the laboratory. Almost all laboratory analyses will be carried out by EMWD’s certified laboratory. Where EMWD's laboratory does not perform the analysis, samples will be sent to an outside laboratory.

Phase 3: Optimization Operation. Once the 6‐month testing of the unit at 80 percent recovery has been completed along with the performance assessment of the modified precipitator reactor, including the materials balance, the project will move into a second period of operation. During this period, the process performance will be optimized. This will include making any modifications to the precipitator system in order to perhaps improve performance based on the first test period results, as well as determining whether the recovery of the system can be increased beyond 80 percent. If, for example, the recovery could be increased to 85‐percent, the overall recovery of the desalters would increase from 95 percent to 96.3 percent. However, increasing the recovery will potentially come at a cost to the product quality as well as the electrical power consumption. These factors will be assessed during this phase of the operation to determine the optimal configuration and operating conditions for a full‐scale system.

The sampling matrix for this test period will be similar to the one presented in Exhibit 2‐1, however, the frequency of sampling is expected to be lower. The actual sampling matrix will be developed at the start of second test period once the optimization scenarios have been decided. Additionally, the equipment to dewater the waste solids produced in the Precipitator will be evaluated. A full‐scale system treating 2.3 mgd of RO concentrate is anticipated to produce about 450 pounds per hour of solids for disposal. Therefore, the dewatering and truck loading facility will be an important component of the full‐scale system. Testing of the dewatering capabilities of various technologies to determine their capital and operating costs is needed to determine the most suitable system for full‐scale implementation. The 100 gpm unit is expected to produce about 25 pounds per hour of solids, which should be adequate to allow for realistic testing of dewatering equipment.

The operating voltages and energy consumptions, chemical utilizations and replacement of all consumables will be recorded to establish an accurate cost estimate.

Phase 4. Decommissioning. Depending on the overall outcome of the testing, it is possible that the 100‐gpm system will not be decommissioned at the end of the testing period, but may continue operation in order to develop any further design criteria needed for the full‐scale system implementation. In addition, EMWD will have invested a significant amount in the 100 gpm unit, and it may be beneficial to keep the system operating as a training tool for operators to prepare for the full‐scale facility.

12

The probability of success of this project is moderate to good. Previous work on the 8‐gpm pilot process described above has proven the technical feasibility of the AquaSel process to treat Menifee concentrate and operate at 80 percent recovery. Based on the previous work and the lessons learned by GE's technical team, it is anticipated that there is a moderate to good probability of success for the proposed 100‐gpm project.

3 Management Approach Cost effective implementation of this project depends on communications and teamwork; effective project monitoring, schedule, and cost control; and an effective quality assurance/quality control (QA/QC) program. Our project management approach promotes communication and teamwork through the use of a proven workshop approach that builds consensus for project direction, effectively identifies and deals with regulatory coordination and concerns, and results in early project delivery. Our project monitoring and quality control efforts will facilitate smooth project delivery, eliminate cost overruns, avoid project conflicts and bottlenecks, and decrease onsite construction time.

3.1 Communications and Teamwork To ensure design quality through effective teamwork, the EMWD/CH2M teaming process will begin by establishing the outline for project execution in a kickoff meeting. During the kickoff meeting, we will collaboratively establish the approach for the execution of the project to ensure quality work in a timely manner. Throughout the project, our project manager, Fred Soroushian, will act as the liaison with EMWD staff. Each monthly progress summary will cover work completed, work planned, schedule status, summary of major decisions and cost impacts, and a review of outstanding issues and action items. Status reporting will focus on near‐term work efforts as well as keep the team oriented to ultimate project goals and success.

An important feature of our management approach is continued EMWD/CH2M team meetings and workshops. Workshops will be working sessions with EMWD staff to review the progress of the work, facilitate decision‐making, and focus on a common goal of project success. Workshops will be held separate from the regular progress and monthly meetings to provide a forum for key decision making to minimize delays that can result from incorrect assumptions and interpretation of project objectives. Specifically, the workshops will fill the following functions:

o Allow the project team to tap into EMWD staff knowledge and experience

o Assist in building consensus regarding project objectives, approach, and progress in place of numerous individual meetings

o Help ensure the efficient, smooth, and timely production of submittal packages

o Inform all project team members of the effects of process or other decisions on critical aspects of the project

We have included a kickoff meeting and two workshops during planning and design of the AquaSel demonstration facilities as well as quarterly meetings during the demonstration facilities operations. The proposed workshops and tentative activities are as follows:

13

o Workshop 1 will be held to present the draft technical memorandum (TM) “Initial Study Protocol and Regulatory Considerations”, GE scope of supply and the drawings prepared for the 50‐percent design and to receive and resolve EWMD’s comments.

o Workshop 2 will be held to present the final testing Protocol and 100 percent design documents (drawings, technical specifications, bid sheets, and schedule of values)

3.2 Project Schedule and Cost Control To achieve the project goals, we will use two proven techniques: schedule control and design‐to‐cost.

Schedule Control: Schedule control is initiated at the outset of the project in the form of the management plan. A management plan will be prepared for each major phase of project work. These plans detail specific work activities, define deliverables, specify completion dates, assign tasks, and identify critical milestones.

Fred Soroushian will continuously monitor the work progress compared to the schedule and will adjust work activities to avoid schedule slippage. As demonstrated on our previous work for EMWD, we have met schedule requirements for project milestones. This record of successful past performance is your best guarantee that the AquaSel Demonstration Project will be delivered on time.

Design‐to‐Cost: We propose to use design‐to‐cost (cost‐trending) techniques to control project costs. During the preliminary design, we will estimate the cost of your proposed facilities and establish the baseline project budget. As soon as the baseline budget is established, design decisions (changes that significantly affect cost), will be resolved with EMWD. The key to this cost‐control program is the prompt identification of design changes and the quantification of their impacts on the overall project budget. We have used this cost‐trending approach with great success on all our recent design projects.

3.3 Quality Assurance/Quality Control CH2M’s ongoing QA/QC program supports our corporate commitment to provide technically excellent professional and consulting services to our clients (Exhibit 3‐1). Our formal firm‐wide QA/QC program is based on a total quality management approach and provides a solid foundation for ongoing client relationships. Key concepts include the following:

o The client’s perception of quality is the one that counts.

o All members of our management and staff are committed to delivering quality services.

o All of our work should continually add value to the client’s operation.

o CH2M provides highly experienced senior project team members.

QC involves applying all the elements of our QA/QC program to your project activities. This will include developing a QA/QC plan and obtaining EMWD feedback at the onset of the project.

Exhibit 3‐1. CH2M QA/QC Program Continuously Ensures Quality

14

3.4 Safety Program A sound health and safety program will be essential when conducting the activities associated with your project, such as field sampling and piloting. Health and safety at CH2M is maintained through an enterprise‐wide Health, Safety & Environment (HSE) Program. This program establishes priorities and actions for continual program improvement consistent with our Target Zero Management System, which has the goals of:

o Relentless pursuit of achieving zero incidents, illnesses (world‐class safety) o Zero adverse environmental impacts (environmental stewardship)

The efficacy of our HSE program is demonstrated by Verdantix once

again naming CH2M as a leader in environment, health, and safety

(EHS) consulting in January, 2015. This independent analyst firm

found that CH2M has the broadest and most comprehensive EHS

consulting capabilities after comparing 12 leading EHS consultants and interviewing 15 customers across

seven industries for its new Green Quadrant® EHS Technology Services Report.

To implement the same high level of safety for this project, we will develop our Field Safety Instructions

(FSI) to align with your safety guidelines, and will implement the FSI elements at every step of the

project. Execution of the FSI will mean that the FSI is endorsed by all stakeholders at the onset of the

project, is site‐specific for AquaSel Demonstration Project site, and will cover all team members.

4 Project Team As the AquaSel RO concentrate treatment and recovery project moves from pilot testing to a larger scale demonstration, EMWD must be confident in the ability of the team to clearly satisfy EWMD’s expectations for this project. Since RO concentrate consists of a highly complex water quality matrix, treating and recovering RO concentrate streams require in‐depth knowledge of water chemistry and process. Advancing this project also requires design and construction of the facilities, familiarity with applicable regulatory requirements, and understanding of the existing desalters operations and EMWD’s objectives. To meet the project objectives we are offering a combined team of CH2M/Carollo experts. This team brings the best collective knowledge of desalination and RO concentrate treatment, recovery, and disposal. CH2M has designed EMWD’s current desalination facilities and has a great understanding of EWMD’s desalination and water management system, as well as water quality issues that are essential to desalination facility operation and performance. Carollo has evaluated and pilot tested RO concentrate treatment and recovery technologies including SPARRO, forward osmosis, membrane distillation and more recently GE’s AquaSel technology to treat and recover RO concentrate from Perris I/Menifee desalters. CH2M/Carollo team has unmatched familiarity with EMWD’s desalination and water management system, and a comprehensive understanding of your project goals gained through almost 20 years of work for EWMD.

In addition to bringing a team with significant working relationships with EWMD, we are offering a team principally composed of locally based personnel who can come to the site, when needed, to provide trouble shooting and operation assistance. Our principal technologists Jim Lozier and Graham Juby, renowned experts in membrane processes and water desalination, and RO concentrate/brine treatment and recovery, have previously led desalination and concentrate treatment and recovery projects for

15

EMWD. The combined experience of Graham and Jim will be crucial to the optimization of the AquaSel process and success of this project.

Fred Soroushian, who brings 35 years of leadership in the water industry, will serve as our project manager. Fred has served as project manager and has successfully delivered a number of key projects for EWMD including Perris II Preliminary Design, Perris Water Filtration Plant Capacity Expansion, Perris Water Filtration Plant Reject Recovery Conceptual Design, and Temecula Valley Regional Water Reclamation Facility design.

Our team members have been selected on the basis of their technical expertise, their experience with similar projects and familiarity with Perris/Menifee Desalination facility. They are committed to your project and will support Fred in delivering this project in a timely manner. The proposed team and qualifications of our key members are summarized in Exhibits 4‐1 and 4‐2 while detailed resumes for all team members are included in Appendix A.

Exhibit 4‐1. Team Organization Our team is structured to streamline delivery of the demonstration project by key personnel who understand EWMD’s goals and the complexity of the project.

5 Scope of Work EWMD desires to construct, operate, and evaluate a demonstration scale brine reduction technology process using proprietary equipment and processes obtained from GE Water & Process Technologies (GE). The specific process is referred to as the AquaSel process. The scope of work for the AquaSel Demonstration Project is divided in two phases, Phases I and II, as shown below.

Phase I includes initial demonstration study planning and demonstration facility design services. Phase II includes optional tasks related to the engineering services during construction and demonstration system operation. The scope of work for these tasks can be developed in more detail based on the outcome of Phase I tasks and reviewed with EMWD.

Phase I The services under Phase I include the Demonstration Study planning and design activities as described in the following paragraphs.

Task 1 ‐ Initial Demonstration Study Planning 1.1 Negotiation Assistance for Equipment Procurement from GE The Consultant will assist EWMD with negotiating an agreement with GE for AquaSel related equipment procurement with services during commissioning, start‐up and operation of the AquaSel system. The Consultant will assist EWMD with scoping equipment supply, delivery schedule and negotiating the commercial terms for EMWD’s procurement of the equipment as well as GE supports services for the duration of the project. The Consultant will participate in one negotiation meeting with GE at EWMD’s headquarters. Since this is a flagship project for GE representing significant value to both GE and EWMD, EWMD anticipates obtaining the best value with regards to procurement of equipment and services from GE.

In addition to the AquaSel equipment, is assumed that the scope of work and supply by GE will include preparing the operations and maintenance (O&M) manual for the AquaSel system (Task 3.2), leading the Operations Training (Task 3.4) and Start‐up Assistance (Task 3.5). In addition, it is anticipated that GE will provide one full‐time staff onsite for the 1‐year operation period of the facility (initial and optimization phases), and as a part of Task 4 (Services During Demonstration), GE will lead the troubleshooting efforts related to the AquaSel system.

Deliverables GE Scope of Supply and Commercial terms

1.2 Project Siting Assistance EWMD anticipates the demonstration project will be constructed either on the Perris II site or on EWMD’s Menifee and Perris Desalter site, provided space is available. The Consultant will use their knowledge of the site, as well as, information obtained from GE regarding equipment needs, to develop an overall site plan for the project. The Consultant will consider water conveyance to and from the demonstration project and associated project utility needs, as well as work area ingress/egress that will not conflict with existing/planned site activities. The Consultant will participate in one meeting with EMWD at the site to discuss project siting and utility needs.

The key deliverable shall be a preliminary site diagram with an equipment layout for the project that identifies the battery limits of operations and the needed utility interconnections.

6 Project Schedule This project is divided in two phases, Phase I for planning and design activities and Phase II for construction and demonstration system operation activities. Exhibit 6‐1 presents our project schedule for Phase I of this project, created to specifically meet the requirements of this project. Our Phase I project schedule builds on our detailed Scope of Work and allows for timely completion of the negotiations with GE, development of initial protocol, and project design. We will accomplish this by conducting several activities in parallel and convening Workshops to provide the necessary coordination to incorporate the protocol requirements in the design and the AquaSel equipment.

The sequences of activities for Phase I are presented in Exhibit 6‐1 and include the kickoff meeting and design review workshops, which are scheduled at crucial points in the project to receive input from the Stakeholders and EMWD. Throughout Phase I of the project, we will provide EMWD with monthly progress status reports, conduct monthly coordination conference calls to receive EMWD input, resolve any project issues, an allow for timely completion of the project. In addition, our monthly project status reports will provide updates on the budget, schedule and tasks completed. The key factors that make this schedule feasible include:

Our familiar project team includes experts in all areas of desalination and water treatment (including negotiating with GE, design, and coordination with Regulatory Agencies). In addition, our team members designed the Perris I and Menifee desalters and participated in the AquaSel pilot testing with EMWD. Our team is familiar with your desalters, your standards and requirements, and GE’s AquaSel system which results in saving time and avoiding rework. Our team brings dedication to quality and commitment to your projects, as we have demonstrated for EMWD.

Our approach includes conference calls, meetings and workshops at critical stages of the project. We will continue to work closely with you by applying this proactive approach to ensure efficient transfer of information and build consensus for timely decision‐making.

CH2M’s team has all the resources and an experienced project team to execute the project in a timely fashion. The schedule presented in Exhibit 6‐1 is based on preparing one design package to be released to the EWMD’s on‐call contractors for bidding. GE’s AquaSel equipment package will be pre‐negotiated and provided to the contractor for installation. The schedule assumes GE will provide the information necessary for design of the site infrastructure and facilities by June 2016.

The proposed sequences of activities for Phase II, which include engineering services during construction, final protocol development, baseline operation and optimization operation are presented in Exhibit 6‐2.

His expertise is in all areas of membrane WTP design, including membrane softening, reverse osmosis, micro/ultrafiltration, and concentrate treatment and disposal. He has executed all phases of water and concentrate treatment projects, including process selection, conceptual design, pilot testing, detailed design, and construction-phase and startup services. Mr. Yallaly also serves as the Water Treatment Practice Leader for Carollo's Private Sector Group. Specific experience includes:

Relevant Experience Project engineer for the design of the Terminal Island AWPF Expansion. The expansion project completes the buildout of the Terminal Island AWFP by doubling its treatment capacity to 12-mgd (as treated water). The AWPF treatment process uses MF, RO, and UV/AOP to produce IPR quality water for injection into the Dominguez Gap sea water intrusion barrier. The design was completed in the third quarter of 2015, and construction began in the fourth quarter of 2015. The project is being executed using design-build project delivery.

Design manager and lead process engineer for the 6.5-mgd Valencia Advanced Wastewater Treatment Facility for LA County Sanitation District. The facility treats tertiary effluent using microfiltration, nanofiltration, ion exchange, and reverse osmosis to concentrate chlorides for offsite disposal. The treated water blends with tertiary effluent before UV treatment and discharge to the Santa Clara River. The project is scheduled to be online

Lead process engineer for the design of a 2.8-mgd brine treatment facility for a major industrial manufacturer. The process treats RO concentrate from the manufacturing facility using chemical softening, filtration, ion exchange polishing, high recovery reverse osmosis, and thermal evaporation to reduce total brine flows to 60 gpm and recovery high quality product water for reuse by the customer. The project was executed using design-build project delivery and has been operating for nearly two years.

Project manager/engineer for the design and construction phase services for the Chino II Concentrate Reduction Facility (CRF), which treats up to 2.75-mgd of brine from the Chino II Desalter and recovers 66 to 85 percent of the water for potable use. The Chino CRF uses pelletized softening, clarification, media filtration, and reverse osmosis to reduce hardness and silica, and produce high quality potable water that is low in TDS and nitrates. In addition to producing additional potable water and reducing concentrate discharge into the Inland Empire Brine Line, the CRF generates nearly pure calcium carbonate pellets that will be sold and beneficially reused by a local specialty mineral supplier. The project is anticipated to be online in the second quarter of 2016.

Project manager/engineer for the expansion design of the Chino II Desalter from 10 to 20.5 mgd. The expansion is part of the overall Chino Basin Phase III project and was funded by a grant from the State of California and matching funds from three project sponsor agencies (Western Municipal Water District, the City of Ontario, and the Jurupa Community Services District). The expansion design included new cartridge filters, new RO feed pumps, two 3.25-mgd RO trains, a new decarbonator, modifications to the existing transfer pump station, post treatment modifications, and expansion of the nitrate removal the ion exchange system. The project was designed in early 2008 and is projected to be online by December 2009. The expansion components include upgraded features for process control, data monitoring, and facility maintenance.
