WOOLBRZGHT ROAD, BOYNTON BEACH~ FLORZDA~ ON M()NDAYr APR]~L 12, 2004 AT 6:30 P.M. Present: Jerry Taylor, Mayor Nike Ferguson, Vice Mayor Bob Ensler, Commissioner Mack McCray, Commissioner Carl McKoy, Commissioner Kurt Bressner, City Manager Dale Sugerman, Assistant City Manager Jeff Livergood, Public Works Director Bob Kenyon, Deputy Utilities Director Mark Law, Deputy Utilities Director Pete Mazzella, Deputy UUlities Director Mark Bobich, Environmental/Safety Coordinator Paul Fleming, Senior Project Manager Barb Conboy, Manager/Utilities Administration Rick Olson, CH2M Hill John Potts, Kimley-Horn Janet Prainito, City Clerk Mayor Taylor called the meeting to order at 6:35 p.m. City Manager Bressner said that the purpose of this workshop was to discuss a number of utility related capital projects. He explained that this is an update to an earlier workshop that was held last year. That meeting was preparatory to the City receiving the renewal of its Consumptive Use Permit. The City received its permit from the South Florida Water Management District (SFWMD) in August 2003. There are conditions on the permit that the City must comply with. A number of those conditions have a direct bearing on some capital projects. The timing of those activities is governed by the terms of the Consumptive Use Permit. The City is required under the terms of the permit to report annually on its progress. City Manager Bressner explained that the exact timing and the complexity of the projects would be a policy decision by the Commission. Staff will make recommendations. A number of improvements that will be discussed tonight are not required to be done but are recommended. The most significant change in the water permit from the SFWMD was that the City was requested, in very strong terms, to use the Floridan Aquifer and reduce water use from the shallow aquifer. Assistant City Manager Sugerman explained that the presentation tonight builds on a previous presentation made in February 2003. The slide presentation from tonight's meeting is on file in the Office of the City Clerk. He explained that, in addition to the City's East Plant and West Plant, there are also a number of interconnections with other systems and they are working on more interconnections. The SFWMD permit that the City had in 2002 allowed us, on average, to withdraw almost 15 million gallons per day (MGD) of raw water. The average daily raw water demand from customers was 15.63 MGD. We were actually exceeding the requirements of our permit. That is why we were so intent in getting the permit renewed at a higher level. We also had plant capabilities of withdrawing 18 MGD of raw water so customers' demands could be met. The 2003 average raw water demand was 16.26 MGD. Meeting Minutes City Commission Workshop Bovnton Beach, Florida Ar~ril 12r 2004 The peak daily demand for treated water in 2002 was 18.4 MGD. The City had a capability of 20.8 MGD so we were always able to meet customers' demands but we were exceeding our permit. The current peak demand in 2004 is 18.6 MGD. Prior to new developments being approved, they have to determine how much capacity they will need. Once site plans get approved, they have to reserve capacity for their approved plans. Tn February 2003, with projects that had a firm reservation and others that would be coming on line, there was only an unrestricted reserve of approximately 2/3 of a million gallons a day. The plan was to expand the West Water Treatment Plant using surficial wells to a treatment capacity of 16 MGD. This was to be done in two phases. Phase I was to gain an additional million gallons per day by replacing the membranes on the older trains and Phase 2 was to add an additional 7 MGD. This would add 8 I~IGD to the existing 8. Phase 3 was to rebuild portions of the East Water Treatment Plant to add between 8 and 12 MGD of Low Pressure Reverse Osmosis treatment (LPRO). The only thing we can do at this East Plant is go to the deeper Floridan Aquifer. The timeframe at that time was to begin the West Treatment Plant expansion immediately and begin the site plan process at the East Treatment Plant. Assistant City Manager Sugerman explained how they have lived up to the commitments made: · Obtain Water Use Permit - completed · Expand West Water Treatment Plant to 16 MGD - underway · East Plant Site Plan for construction of Low Pressure Reverse Osmosis (LPRO) facility - conceptual plan completed · Downtown sewage system capacity analysis - completed · Develop reuse system master plan - draft completed 1. Current Water Use Permit The seven-year water use permit issued August 14, 2003 had 29 conditions. Most of these conditions are standard conditions. Approximately 12 are pertinent to Boynton Beach. The major conditions are: The East wellfield pumpage has been restricted to 8 MGD average daily flow because of the proximity to the Ocean. The SFWMD is concerned regarding saltwater intrusion. The most critical point is that on a system-wide basis (both East Plant and West Plant combined), during the dry season, pumpage from the surficial aquifer must be reduced to 15.5 MGD by the year 2008-2009. The Water Use Permit requires the City to develop alternative water supplies. This includes an aquifer storage & recovery well #2. This well will be twice the size of well #1 and will be able to handle between 3 million and 4 million gallons per day. This well will be constructed at the East Water Treatment Plant. The wells out west will be surficial because there is no concern regarding saltwater intrusion there. Meeting Minutes City Commission Workshop Boynton Beach, Florida Aoril 12, 2004 Commissioner Ensler commented that the City currently can treat 8 million gallons at the East Plant and 8 million gallons at the West Plant. He questioned why we would add 8 million gallons out west to bring the total to 24 if the permit limits us to 16. Assistant City Manager Sugerman explained that the SFWMD is saying that by 2008-2009, we can use almost 16 MGD surficial water, which is what our West Plant will ultimately provide. What the District is doing, in their subtle way, is shutting down the East Plant from using surficial wells. The East Plant is going to have to go to the Floridan well system. They are telling us that by the year 2010 the East Plant must be 100% Floridan well with Iow-pressure reverse osmosis. City Manager Bressner commented that the City Commission has the ability to request an amendment to the permit if we feel that there is a hardship. He said that he was not suggesting that this be done. Commissioner Ensler said that another option is to leave the plants the way they are and instead of putting 8 MGD into the surficial wells, pump it out of some deeper well at the East Plant. He questioned the economics of building another 8 MGD out west and tearing the East Plant down. Assistant City Manager Sugerman explained that they wanted to save the use of the East surficial aquifer as long as possible. The East Plant was built in 1964. The useful life of a plant like this is typically 50 years. Our seven-year permit will take us to the point that we have almost gotten the useful life out of this plant. The District is not telling us to tear this plant down. However, they are subtlety telling us to go ahead with surficial out West but go to the Floridan at the East Plant. Commissioner Ensler felt that there were other options to consider. Assistant City Manager Sugerman said that the Water Use Permit calls for the following alternative water supplies: · ASR Well #2 along with Well #1 that is already in place · The wastewater reuse system expansion · The Floridan Aquifer Supply Wells, treated with LPRO technology Although the District will not admit it, they generally tell us behind closed doors that use of the Floridan Aquifer and LPRO is just about unlimited. You can get a permit for any amount you want. The design for the Aquifer Storage & Recovery Well #2 is 90% complete. Tt will provide an additional 3 to 4 MGD of dry weather water production. They anticipate it becoming operational in July 2005. 3 Meeting Minutes City Commission Workshop Bovnton Beach, Florida April 12, 2004 A program manager has been designated for the West Water Treatment Plant expansion. :It is anticipated that in August 2004 we will have the bid opening and they feel that the plant could start up by May 2006. East Water Treatment Plant Phasing Plan including conceptual design and project implementation schedule The conceptual site plan for the East Water Treatment Plant has been delivered. The Task Order authorization is targeted for a City Commission meeting in May. Tt will include a series of preliminary studies for siting 10 new upper Floridan aquifer water supply wells, the routing of 4 miles of raw water pipeline and constructing 8 MGD of the LPRO water treatment with 5 million gallons of ground storage tank. With an LPRO process, we must also select a method of rejecting the concentrate disposal. Assistant City Manager Sugerman shared a chart showing demand, limitations and capacity. He thanked .lohn Ports from Kimley-Horn for providing the chart. Mr. Ports said that it was important to note that this includes the 8 million gallons of LPRO at the East Plant. If this were not included, the capability line would be much lower. Assistant City Manager Sugerman reminded the Commission that if the demand goes above the permit allowance, they could still supplement from the ASR well and some of the alternative water sources. Draft Sequencing Plan for the Reclaimed Water System Project including an estimate of construction This draft master plan has been completed. Obviously, there are benefits to using reclaimed water, l:t will help us to meet the Water Use Permit conditions and will allow us to recapture potable water capacity that is now being used for irrigation. Tnterim Improvements Wastewater Collection System (Odor Control effort with SCRWTD Board) (d/scussed out of order) Concerning the Master Lift Station #356, which is the Downtown basin, there is a required pump station and force main upgrades and additions. We are also doing an inflow and infiltration study. There are two component parts of the odor and corrosion control. There is the actual issue at the plant. There is also the issue of the collection system in both Boynton Beach and Delray Beach. There is an authorization anticipated for the April 15, 2004 Regional Board for a $75,000 study for odor and corrosion control. 4. Draft Utilities Department Capital Improvement Plan through Year 20:L0 Assistant City Manager Sugerman reported that the seven-year Capital Tmprovement Program is contained in the packets provided to the Commission. Tt includes the costs associated with all the major projects at the East and West Plants, the neighborhood projects, all the repair and 4 Meeting Minutes City Commission Workshop Boynton Be~¢h, Florida April 12f 2004 replacement and all the daily operations. They provided a proposed draft plan for the next seven years. It is the Commission's decision when it wants these things to roll out. Staff gave an outline but it is the Commission's call when to do these things. Commissioner Ferguson asked what the cost would be if we converted all the wastewater. Assistant City Manager Sugerman said they did not have the answer yet, but it is something that must be figured out. Commissioner Ensler asked whether going deeper with the wells helps to minimize saltwater intrusion. Mr. Mazzella said that, in general, going deeper along the coast increases the likelihood of saltwater intrusion. 5. Consideration of Authorizing a Cost of Service Study Assistant City Manager Sugerman said that the Commission would need to help staff with priorities and sequencing for all the projects. There will have to be funding sources. We do have some funds. However, in order to complete the projects, we will have to borrow money, modify rates or get more grants. Staff believes that one of the best ways to make the decision is to do a cost of services study. Assistant City Manager Sugerman explained that once the Commission authorizes it, the study would be completed in 4 to 5 months. The cost is $43,500. This item is on the next Commission agenda. This study will help review the equitable distribution of rates. Tt will also update our capital facility charge. The third thing it will do is provide an engineer's report that could be used in a possible future bond issue. City Manager Bressner noted that staff would come to the Commission with a list of projects in mid-May. Assistant City Manager Sugerman reported that as of April 2004, the reserve capacity was down to 2.2 MGD because more developments have bought capacity. There is an identified near- term demand of 2.7 MGD. Therefore, if everyone would come in and buy their reservation, we would be in a 1/2 million gallon per day deficit. City Manager Bressner asked whether there was any legal reason that the City could favor utility customers inside the corporate limits or are we required to accept reservations for water use for unincorporated areas. Assistant City Manager Sugerman did not know the answer. :If they have an approved site plan, because the City has a dedicated service area, and they pay their reservation fee, we must give it to them. He did not know whether we could pick and choose and would have to defer to City Attorney .lames Cherof. Commissioner Ensler asked regarding the purchase of transmission lines in the City for the reuse plant and whether we should take on the contracts for the five golf courses with the reuse water. MeeUng Minutes City Commission Workshop Boynton Beach, Florida Aoril :~2, 2004 City Manager Bressner reported that we are running the numbers now as to the value of the lines. The lines that were installed were built with funds from both Delray Beach and Boynton Beach. The City of Delray Beach has not benefited from the use of those lines because none of the users are in the City of Delray Beach. The conceptual conversation at a staff level was that since the cities contributed to the cost of those lines and Delray Beach has not gained a beneficial use of the lines, we would pay back into the fund one-half of what that cost was. Tf we take charge of the wastewater recharge line, then the question is what opportunity does the City have in terms of either adjusting rates in the future or receiving revenue from it. This is being discussed and analyzed now. :In order to control the destiny of that line, it may be in our interest to take over ownership of the line. Herb Suss asked whether rates would increase to pay for all of this. Mayor Taylor said that the study would answer that. Mr. Suss felt that the highest users should pay more. Assistant City Manager Sugerman said that the recommendation would most likely be that the highest users pay the most. Assistant City Manager Sugerman announced that Mark Law, Deputy Utilities Director, is retiring from the City of Boynton Beach after 281/2 years of service. He wished Mr. Law health and happiness and thanked him for the many, many years of great service to the City. Mark Law said that his family has been in the Boynton Beach area since the 1950's. He has worked with many City Commissions and said they have always been very generous. He thanked City Manager Bressner for his dedication. Most of all, he thanked the Utilities team.

As necessary to offset the interference, mitigation will include pumpage reduction, replacement of the impacted individual's equipment, relocation of wells, change in withdrawal source, or other means. Interference to an existing legal use is defined as an impact that occurs under hydrologic conditions equal to or less severe than a 1 in 10 year drought event that results in the: A. Inability to withdraw water consistent with provisions of the permit, such as when remedial structural or operational actions not materially authorized by existing permits must be taken to address the interference; or B. Change in the quality of water pursuant to primary State Drinking Water Standards to the extent that the water can no longer be used for its authorized purpose, or such change is imminent. Permittee shall mitigate harm to existing off-site land uses caused by the permittee's withdrawals, as determined through reference to the conditions for permit issuance. When harm occurs, or is imminent, the District will require the permittee to modify withdrawal rates or mitigate the harm. Harm as determined through reference to the conditions for permit issuance, includes: A. Significant reduction in water levels on the property to the extent that the designed function of the water body and related surface water management improvements are damaged; not including aesthetic values; The designed function of ~a water body is identified in the original permit or other governmental authorization issued for the construction of the water body. In cases where a permit was not required, the designed function shall be determined based on the purpose for the original construction of the water body (e.g. fill for construction, mining, drainage canal etc.). B. Damage to agriculture, including damage resulting from reduction in soil moisture resulting from consumptive use; or C. Land collapse or subsidence caused by reduction in water levels associated with consumptive use. Permittee shall mitigate harm to the natural resources caused by the permittee's withdrawals, as determined through reference to the conditions for permit issuance. When harm occurs, or is imminent, the District will require the permittee to modify withdrawal rates or mitigate the harm. Harm, as determined through reference to the conditions for permit issuance includes: A) Reduction in ground or surface water levels that results in harmful lateral movement of the fresh water/salt water interface, B) Reduction in water levels that harm the hydroperiod of wetlands, C) Significant reduction in water levels or hydroperiod in a naturally occurring water body such as a lake or pond, D) Harmful movement of contaminants in violation of state water quality standards, or E) Significant damage to the natural system including damage to habitat for rare or endangered species.

EAST WATER TREATMENT PLANT PHASThI~ PLAN ,3'ANUARY 20, 2004 TECHNICAL MEMORANDUM CFi2MHILL East Water Treatment Plant Phasing Plan PREPARED FOR: City of Boynton Beach Utilities Department PREPARED BY: CH2M HILL DATE: January 20, 2004 This Technical Memorandum presents a phasing plan for implementing proposed improvements to the City's East Water Treatment Plant (WTP). The plan includes a description of the scope of work for each phase, a discussion of implementation issues, and an implementation schedule for Phase 1. Background The City of Boynton Beach's East WTP employs lime softening, disinfection, and fluoridation in its production of drinking water for its water customers. Currently, the City draws water from the Surficial aquifer for production at its East WTP. The plant is rated for approximately 19 million gallons per day (mgd) capacity by the Florida Department of Environmental Protection (FDEP), however, has a hydraulic capacity in excess of 25 mgd. The City has been an effective steward of the groundwater resource monitoring water quality and safe allocation, however, regional water quality shortages, periodic droughts, and fluctuations in grotmdwater quality, have directed the South Florida Water Management District (SFWMD) to limit the availability of water withdrawals from the Surficial aquifer. To this end, the City has been required to reduce groundwater with- drawals to an average of 8 mgd. This has enabled the City to continue producing drinking water in compliance with FDEP regulations and to satisfy the limilS_ng conditions imposed by the SFWMD. To continue to meet the regulatory requirements and the growth of Boynton Beach, the Utilities Department plans to add membrane treatment to the East WTP. The proposed membrane treatment process will replace some of the capacity lost by the reduction in allocation of the East well field and will increase water production capacity. The proposed system will be a low pressure reverse osmosis (LPRO) treatment system with the feed source originating from the Floridan aquifer. With this technology the City will be able to utilize water from deeper aquifers where saltwater intrusion is not an issue. Along with the modifications to the treatment system, the City plans to implement major improvements to the East WTP site to make it compatible with the redevelopment of the Woolbright Road corridor. The City plans to implement the above improvements in three phases over a ten year period. Scope of Work The following is a discussion of the major work scope items in each of the three implementation phases. TECHNICAL MEMORANDUM BOYNTON EAST WTP PHASING EVALUATION_011904.DOC/033640005 1 162966.GE.01 EAST WATER TREATMENT PLANT PHASING PLAN Phase 1 - Installation of Low Pressure Reverse Osmosis Water Treatment Plant The first phase of work consists primarily of adding 8 mgd of capacity from LPRO treated water. Work for Phase 1 should begin in early 2004 in order to have the treatment process operational before Aug-ust 2008. The City will continue concurrent operation of the lime softening system, at a capacity of approximately 8 mgd. Major elements of work in Phase 1 are described in the following subsection: Membrane Pilot Testing- Pilot testing will be conducted to identify suitable membranes for treatment of Floridan Aquifer water from the new production wells. The pilot test will provide the City with data on critical information relating to the design of the membrane system such as: · Pretreatment requirements for site-specific current raw water quality · Permeate characteristics · Ability to by-pass and blend raw water with permeate (i.e. sizing of membrane capacity) · Concentrate characteristics for use in evaluating the feasibility of discharge options. It is proposed that water samples to conduct the membrane pilot testing will be provided from the new multi-purpose well that will be constructed on the East WTP site. Water Supply System- To meet the ultimate build-out capacity of the East WTP, it is anticipated that between 9 and 10 new Floridan aquifer wells (each producing 1500 gallons per minute [gpm]) will be required. During Phase 1, a study will be necessary to site the new well facilities and to model their impact on adjacent users of the Floridan Aquifer. To determine the characteristics of new wells and water quality, the proposed multi-use Well (currently being designed for the East WTP) will be tested during the construction phase to project supply well performance. Following the completion of construction, the multi-use well will be utilized as an Aquifer Storage and Recovery (ASR) well, however, it may be converted to a supply well or upper zone monitoring well in the future. It is proposed that all of the supply wells be sited and constructed during Phase 1. In addition, new well-head (pumps, instrumentation, and controls) and pipelines will be necessary to bring the new wells into service. The City will then need to modify its existing Water Use Permit (WUP) application to permit the construction of the new Floridan aquifer wells. Membrane Treatment System - Under the conditions of the current WUP, the City is committed to adding 6 mgd of LPRO water by the summer of 2008. However, based :on projected water needs and the balance between the City's two treatment plants, it is anticipated that the first phase of the treatment system will have 8 mgd of capacity. The facility will be constructed so that the capacity can be expanded to 16 mgd (during Phase 2) to accommodate the anticipated decommissioning of the lime softening plant (nearing its 50 year design life) and the anticipated growth in water demand. The City intends to size Phase 1 facilities to accommodate the future 16 mgd system. Plant Control System - During Phase 1, the City will operate the lime softening system in parallel with the new membrane treatment system. Each process requires a unique set of. controls and will be operated independently. A new computer-based control system for the membrane softening system will be located in the new plant treatment building. When Phase 2 is implemented, the lime softening system will be demolished and total control of the treatment system will be housed in the membrane process building. TECHNICAL MEMORANDUM BOYNTON EAST WTP PHASING EVALUATION_011904.0OCI033640005 2 EAST WATER TREATMENT PLANT PHASING PLAN Laboratory - In Phase 1, a new process laboratory will be constructed in the membrane process building. This basic wet chemistry area will permit the direct delivery of raw, finished, and concentrate water to the laboratory and permit operators to perform basic analysis on site. The City will continue to use the laboratory at the West WTP which conducts more complex analyses. On-Site Generation of Sodium Hypochlorito (Optional) - The City is considering the addition of a new on-site, sodium hypochlorite generation system for the East WTP. If it is decided to pursue this option, the facility should be built within the new water treatment plant building during Phase 1. The system could supply liquid sodium hypochlorite to both treatment systems (the lime softening plant and the new LPRO systems) or just supply the new facility. The on-site generation system could be comprised of a minimum of two sodium hypochlorite generators, salt/brine storage tanks, sodium hypochlorite storage tanks, and chemical dosing pumps. Road access to the tanks is needed for delivery of salt and delivery of bulk liquid hypochlorite as a backup to the on-site generation system. The existing chlorine gas system (serving the lime softening plant) could then be phased out when the on-site generation system becomes operational. If it is decided to use bulk deliveries of liquid sodium hypochlorite as the primary disinfection method, storage tanks should also be placed within the new water treatment plant building. Storage in this location will increase the life of the product by protecting it from high temperatures and ultra-violet light. Concentrate Disposal System - The new LPRO water treatment process will generate a waste stream referred to as concentrate. The concentrate is a brine solution consisting of salts rejected by the membranes. Options for disposal of concentrate include deep well injection, shallow well injection, sanitary sewer system discharge, and surface water discharge. The City will need to conduct a study of these options and determine the best available option from a permitting and cost effectiveness vantage point. Concentrate disposal facilities will be sized for the full Phase 2 capacity requirements but, depending on the selected option, may be constructed in phases. Ground Storage Tank- A new 5 million gallon ground storage tank is planned in Phase 1. Ground storage will be necessary to provide a reservoir of treated water that can meet the varying water consumption demands. Ground storage will be needed to replace the clear well located in the existing 1/me treatment process building and meet the Recommended Standards for Water Works (Ten-State standards) and FAC 62-555. Site Development- Significant site improvements are planned in Phase 1 including enhanced security of the water treatment process buildings, new stormwater management ponds, additional parking spaces, perimeter buffering, internal landscaping, and a new sanitary lift station. The City has the option of relocating ancillary activities and storage to other, off-site locations or to position them in the location currently occupied by undeveloped space at the East WTP. The area currently used for the lime sludge drying area will be partially used for a new 5 million gallon ground storage tank. Because the City is operating the lime softening system at a significantly reduced capacity, it is recommended that the area provided for the lime sludge lagoon and drying be reduced by approximately 50 percent and that the existing sludge drying area be shifted to accommodate the new facility. TECHNICAL MEMORANDUM BOYNTON EAST WTP PHASING EVALUATION_011904.DOOd033640005 3 EAST WATER TREATMENT PLANT PHASING PLAN Phase 2a -I. PRO System Expansion During Phase 1, the City will add 4 mgd of new capacity and 4 mgd of replacement capacity. It is anticipated that a second expansion (Phase 2a) will occur within 5 years of the completion of Phase 1 and be operational by 2013. During Phase 2a, the lime softening plant will be fully decommissioned and the capacity of the membrane treatment system will be expanded to 16 mgd. Phase-out of the lime softening system will include the demolition of the lime softeners, filters, ancillary systems, lime sludge processing and storage areas, filter backwash water recovery system, clearwells, high service pumps, and the chlorine storage building. The expansion of the new LPRO system will include the addition of 8 mgd of membrane treatment, construction of a second 5 million gallon grormd storage tank, the installation of a new fluoridation system (relocated from the existing lime softening plant), and the activation of the additional Floridan Aquifer wells (constructed during Phase 1). All activities associated with Phase 2a can occur prior to the demolition of the existing water treatment plant. Phase 2b - Additional Site Improvements Supplemental facilities could also be incorporated at the East WTP site during Phase 2b. These improvements could occur anytime after the demolition of the lime softening plant (scheduled to occur early in Phase 2a). The existing Administration Building could be refurbished and/or expanded and additional site improvements could be pursued. In addition to the administration complex, proposed Phase 2b site improvements could include additional stormwater retention, improved traffic access, supplemented parking, and the addition of an enhanced entry feature at the intersection of Woolbright Road and Seacrest Boulevard. Phase 2b activities include only administrative facilities, site work, and aesthetic improvements to the East WTP site; no process or capacity modifications are planned for this phase. The fully implemented process and site improvements are depicted in the site plan rendering previously prepared by CH2M HILL and included as an attachment to this memorandum. More details regarding the Phase I improvements and implementation considerations are provided in Attachment 1 of this memorandum, while a figure illustrating the entire site development plan is provided as Attachment 2. Construction Services Procurement Approach The City plans to procure construction services by the conventional design-permit-bid-build approach. Phase 1 work consists of large scale specialty work including water supply well drilling, injection well drilling (or construction of other means necessary for concentrate disposal), and pipeline construction. The WTP work will be performed by a general mechm~ical contractor. The City will need to decide whether or not to bundle this work into a single bid package or multiple packages. An example of multiple packages would be one each for supply well drilling, injection well drilling, off-site pipelines, and WTP construction. The following is a discussion of the advantages and disadvantages of each approach: TECHNICAL MEMORANDUM BOYNTON EAST WTP PHASING EVALUATION_011904.DOC/033640005 4 EAST WATER TREATMENT PLANT PHASING PLAN Multiple Contract Packages - Pros - Better City control of individual contractors Reduced mark ups to be paid by City Cons - Increased management costs for multiple contracts Fewer or Single Contract Packages - Pros - "One stop shopping" for City with single responsible party Cons - Increased mark up costs by prime contractor Regardless of the approach selected, it is recommended that the City prequalify contractors for all work at the East WTP prior to advertising the work. Well construction, membrane system, and mechanical piping construction should be performed by experienced, qualified finns. The prequalification process will allow the City to screen out firms who may not have the experience or resources to perform the work. Prequalification will be easier under the multiple contract packages approach. Implementation Plan Attachment 3 presents an implementation schedule for Phase 1 showing completion before August 2008. The duration shown for tasks is based on typical projects and depict average conditions. Should major problems or unanticipated constraints arise, additional time may be needed for completion. The critical path activity appears to be implementation of the membrane treatment system which should be started in January 2004. The City should consider starting the supply wells implementation and concentrate disposal implementation tasks earlier than shown on the schedule. Experience has shown that supply well implementation can take longer than planned due to permitting and site acquisition difficulties and constraints on work schedules. Concentrate disposal can get tied up in permitting difficulties, especially if an tmcommon method is pursued. For this reason, it is our recommendation that the City pursue an early start date for all activities to insure a timely completion. TECHNICAL MEMORANDUM BOYNTON EAST WTP PHASING EVALUATION_011904.DOC/033640005 5 EAST WATER TREATMENT PLANT PHASING PLAN Attachment 1 Supplemental Information The following attachment provides an expanded explanation of the proposed Phase 1 improvements and the implementation considerations: Membrane Process Building The membrane process building will house the following major components: · Pretreatment system · Feed pumps · Membrane system · Sodium hypochlorite system · Basic laboratory · Plant Control Room The pretreatment system will consist of a sulfuric acid feed system, for pH adjustment of the raw water, a scale inhibitor feed system, and cartridge filters. High-pressure feed pumps, one dedicated to each membrane skid, will pump the raw water through the membrane system. The membrane system will consist of multiple piping skids containing the membranes. A common membrane cleaning system containing a chemical tank, recirculation pump, and cartridge filter will also be provided. External to the Process Building will be the degassifier/scrubber system to remove dissolved hydrogen sulfide (H2S) and carbon dioxide from the permeate. The system may consist of the following: · One packed column counter-current degasifier tower · Centrifugal Blowers with air filters · One or two-stage hydrogen sulfide wet scrubber with chemical feed system (caustic and sodium hypochlorite) Product transfer pumps will pump the water from the clearwell to the on-site ground storage tank. Depending on which concentrate disposal system is implemented, additional treatment and pumping facilities may also be needed to treat the concentrate prior to discharge. Space will be provided in the process building for the fully automated, plant control room. The Utilities Department is considering the addition of on-site sodium hypochlorite generation to the East WTP. Other options for disinfection include the delivery of gaseous chlorine or bulk liquid sodium hypochlorite. It is our recommendation that the disinfection system, regardless of method, be located within the process building, should be sized for plant build out (to occur during Phase 2a), and should be installed during Phase 1. We also recommend that the disinfection systems within the new water treatment building supply TECHNICAL MEMORANDUM BOYNTON EAST VVTP PHASING EVALUATION_011904.DOC/033640005 6 EAST WATER TREATMENT PLANT PHASING PLAN only the new LPRO system rather than monitoring, metering, and distributing disinfection agents across the water treatment plant site. Implementation Issues Prior to proceeding to final design of the Phase 1 improvements, there are certain issues which must be resolved by the City. The following is a discussion of these issues: Concentrate Disposal Options There are numerous feasible options available to the City for disposal of concentrate including deep well injection, shallow well injection, sanitary sewer system discharge, and surface water discharge. It is not anticipated that reuse of the concentrate will be feasible unless it is diluted to acceptable levels with reclaimed wastewater. At this time it is anticipated that the concentrate will represent approximately 20 percent of the raw water and will need to be diluted to less than 250 milligrams per liter (mg/L) chlorides before it could serve as re-use water. Depending on what disposal option is selected by the City, a back up, or redundant, disposal method may also be needed. It is our recommendation that the City conduct a study of the disposal options and prepare a conceptual design early in the Phase 1 planning process to aid in the acceptance and permitting of the new disposal system. A Class I deep injection well, similar to the one at the City's West WTP, could be constructed on site. Such a facility would require 4 months to design, up to 12 months to permit, and an additional 9 months for construction. This option places the greatest control in the City's hands as it is an acceptable, permittable option and the land is available on the East WTP site. It can also be assumed that residual plant pressures would be sufficient to convey and discharge the concentrate into the well. Another possibility is the use of Class I shallow injection wells. If pursued, shallow injection wells would be located offsite, east of the WTP and east of US-l, where the underlying shallow aquifer contains total dissolved solids (TDS) in excess of 10,000 mg/L. Property would need to be acquired for these wells and a transmission main and manifold would convey the concentrate to the individual wells. A potential location for the shallow disposal wells would be along the Intra -Coastal Waterway (ICWW) and within the parking lot of Causeway Square Shopping Center. A pipe line leading to the disposal wells could be constructed using traditional open trenching methods or using directional drilling techniques. It can be assumed that residual plant pressures would be sufficient to convey and discharge the concentrate into the wells, however, the specific aquifer characteristics will determine the need for injection pumps. A potential concern with shallow injection is the impact that the shallow wells may have on the water quality of the Surficial aquifer. Because the City will continue to utilize the Surficial aquifer during Phase 1, this may be an tmacceptable option. Discharge of the concentrate to the sanitary, sewer system is also an option. There would need to be adequate capacity in the conveyance system and the regional wastewater treatment plant (WWTP) to process the concentrate (approximately 3.2 mgd). Additionally, impacts of the concentrate on the current disposal practices of the WWTP would need to be assessed as far as water quality and the desire to supply re-use. Finally, if this option is TECHNICAL MEMORANDUM BOYNTON EAST VVTP PHASING EVALUATION_011904. DOC/033640005 7 EAST WATER TREATMENT PLANT PHASING PLAN pursued, the new lift-station and its associated conveyance systems proposed to be located at the East WTP should be sized to accommodate the additional flow. Surface water discharge to the Intracoastal Waterway or the Atlantic Ocean is also potentially feasible. This system would require a conveyance pipeline and outfall diffuser. Prior to considering this option, the City would need to conduct membrane pilot testing to characterize the reject water, perform bioassays on the concentrate, and demonstrate that the concentrate water would meet Marine Waters Standards. This process would require a NPDES discharge permit to be issued by FDEP/EPA. It is anticipated that discharge into the ICWW in Boynton Beach would be unacceptable due to the shallow and narrow nature of the water way. A more palatable option would be to obtain a Coastal Discharge Permit which would require an outfall to be constructed several hundred feet off the ocean shore. Either option would require the negotiation of right-of-way access and appeasement of potential permit dissention. Either outfall could be constructed using a combination of traditional open cut excavation and directional drilling. It is anticipated that directional drilling would be a more efficient technique as the pipeline would need to pass under the FEC rail road, US-l, the ICWW, and SR A-l-A, and the Atlantic coast. For the purposes of this Phasing Plan, it will be assumed that the City will construct an on- site deep injection well with backup discharge to the sanitary sewer system. The City will need to conduct a study of the concentrate disposal options to determine the most feasible option. Regardless of the selected disposal method, the City should conduct a feasibility analysis, prepare a conceptual design, enter the pre-permitting process, and then receive agency concurrence prior to proceeding to the final design phases of the project. Concentrate disposal will be on the critical path of the Phase I expansion. A final consideration with concentrate disposal is changing water quality. Currently the Floridan Aquifer is an underutilized resource with few municipalities in the Central Palm Beach area tapping into its formation. It is anticipated that over time, greater pressures will be placed on the aquifer as a source of water supply resulting in a decline in water quality (increase in TDS). As a result, the recovery efficiency of the plant may decline over time and the volume of reject water may increase. This long term prognosis should be considered when developing the plan for concentrate disposal. Wellfield Site Acquisition & Permitting A total of 9 to 10 well sites are needed during the full expansion of the East WTP. It is recommended that the City secure all of the necessary sites during Phase I to avoid future challenges of land acquisition. The City should begin immediately to identify and acquire the well sites and raw water main corridor. The City should plan on six months to identify prospective well sites and another twelve months to procure the sites. It is possible that the City can co-locate some of the new Floridan Aquifer wells with existing, surficial well sites; thus reducing the site acquisition effort. The City has a Water Use Permit (WUP) from the SFWMD that commits the City to provide 6 mgd of Floridan Aquifer water by 2008. The City's WUP will have to be modified to obtain approval to construct wells in specific locations. The SFWMD will require the City to perform groundwater modeling to demonstrate that there are no adverse impacts to other users of the Floridan Aquifer (Manalapan, Delray Beach). This criteria must be satisfied before the District will approve construction permits for the new wells. After the well TECHNICAL MEMORANDUM BOYNTON EAST WTP PHASING EVALUATION_011904.DOC/033640005 8 EAST WATER TREATMENT PLANT PHASING PLAN construction is complete, the City must submit well completion reports as a condition of the SFWMD approval of the WUP modification application. The City plans to construct a multi-use well on the East WTP early in 2004. Prior to going into operation as an ASR well, the well will be used for the purposes of characterizing the aquifer, which will be used for subsequent modeling of the new water supply wellfield and membrane pilot testing. In the future, the multi-use well may be converted to a Floridan Aquifer supply well, upper zone monitoring well, or remain as an ASR well. After the modeling is completed and the District's requirements for the WUP modification have been satisfied, the City can proceed with the design and construction of the new wells and raw water transmission mains. Depending on the location of the new well sites, the City may have to place constraints on the well driller's work schedule. For example, work done in a public park or school property will have to be performed to suit the administrators of those facilities. Such constraints could effect the completion schedule for the well drilling. Although not critical to the Phase I implementation, the City will need to decide on the future of the existing Surficial aquifer wells. Options for their disposition include abandonment, continued limited use, irrigation (for the Little League complex and cemetery), or conversion to ground water monitoring wells. Vehicle Parking & Storage Parking space is an issue at the East WTP. During Phase 1, additional parking will be added arotmd the new membrane process building to accommodate site workers. For the administrative area of the site, the guest parking area is inadequate and the traffic pattern (one entrance) is insufficient. During Phase 1, the possibility to convert Arbor Park into temporary parking should be pursued. This area may ultimately be converted into a significant, landscaped, entrance feature. At that time, parking will be moved behind the administrative building into an unsecured area that is isolated from the water treatment process. In addition to automobiles, the City currently parks equipment at the East WTP including generators, pumps, and vac-trucks. It is recommended that from an aesthetic, security, and efficiency stand-point, that the non-essential equipment and storage facilities be relocated to an off-site facility. The City may consider purchasing a site in an industrial area or using an existing parcel of land owned by the City located near 1-95 and the C-16 Canal. Additionally, two maintenance buildings and stockpiled materials will need to be removed from the site to free up space for the Phase I facilities. An option to relocating these materials and equipment off-site would be to expand the East WTP into the undeveloped land on site. This option would entail shifting the proposed water treatment process buildings approximately 150 feet to the south and adding a storage / maintenance area between the administration building and the plant process facilities. Lift Station Although not part of the water treatment plant expansion, it has been proposed that a new semi-master waste water lift station be constructed at the southwest corner of the East WTP to off-burden the 356 Lift Station. The existing 356 Lift Station is located near the intersection of NE 6th Street and Casa-Loma Boulevard (just west of the Banana Boat Restaurant) and is currently overburdened. The 356 Lift Station re-pumps the majority of the sanitary waste water generated in Boynton Beach east of 1-95. The new lift station would off-burden the 356 TECHNICAL MEMORANDUM BOYNTON EAST WTP PHASING EVALUATION_011904.DOC/033640005 9 EAST WATER TREATMENT PLANT PHASING PLAN system by intercepting waste water flowing north on Seacrest Boulevard and pumping it west to Congress Avenue. The proposed lift station would be underground, have a capacity of approximately 2,000 gpm, and would require a dedicated area of approximately 50-feet by 50-feet. Undoveloped Land Approximately 1.4 acres of land is undeveloped at the East WTP site. The area (along the southem property boundary) appears overgrown with invasive exotic species. To accomplish the proposed Phase 1 site improvements, it is recommended that the area be developed to accommodate additional storage and parking at the East WTP site. This area could be used for the water treatment plant process building or could be developed for storage and maintenance. In either case, the development of this land does not appear to present either a logistic or permitting hurdle.

DOC/033640005 12 rn RECOMMENDED RECLAZMED WATER SYSTEM PRO3'ECT$ FROM $ECT'J:ON 5 DRAFT' MA$TER PLAN Section 5 Recommended Reclaimed Water System Projects 5.1 Project Overview This section presents the recommended development of the Reclaimed Water System for the City of Boynton Beach. The following list of tentative projects was developed based upon the results of the hydraulic water modeling presented in Section 4 and the City's selection of Option 2 which includes two booster pump stations. The East Booster Pump Station will be located at the City's L.S. 356 site at East Boynton Beach Boulevard and will boost system pressures for the portions of the City north of Boynton Beach Boulevard and roughly east of Congress Avenue. The West Booster Pump Station will be located at the City's West Water Trealment Plant on West Boynton Beach Boulevard and will--boost the system pressures north of Boynton Beach- Boulevard and west of Congress Avenue. The proposed reclaimed mains located between the SCRWWTP and the East Booster Pump Station or the West Booster Pump Station can be constructed in a logical order as they extend from the SCRWWTP. This assumes the treatment and reclaimed water transmission pumping upgrades at the plant have been completed. The east and west systems can operate from the upgraded pumps at the SCRWWTP until the system losses drop the delivery pressure below 50 psi. At this point, the booster stations are required in order to boost the pressure for adequate system pressures beyond the stations. Upon the completion of the stations the project construction can continue in a logical order as they extend fi:om the booster stations. An overall exhibit of the proposed projects is presented in Figure 5-1. Individual project exhibits are provided after each project, including an engineer's opinion of probable construction costs. A summary of the project listing and engineer's opinion of probable construction cost for the entire Reclaimed Master Plan is presented in Table 5.1. All costs are presented in Year 2004 dollars. This table also indicates an estimated project cost per gallon per day delivered to the customer. The costs for the expansion of the treatment unit(s) for additional capacity at the SCRWWTP or additional pumping costs for reclaimed water delivery from the SCRWWTP are not included in the project cost estimates. The system was modeled to provide reclaimed water delivered to a service point location at or near the property. The cost estimates do not include the distribution system internal to the properties. The lines are sized to provide a minimUm of 50 psi delivered at the service point. Costs to re-boost the water (to provide additional pressure at the delivery point), are not included in these estimates.
