VISITORS Mr. Jack Polans discussed the concern of public input and what the solution could be? Chair Manning asked Mr. Polans for the names of people that would be interested in becoming involved in a public input group and that she would be willing to set up a meeting time to discuss public input training and concerns. Chair Manning also invited Mr. Polans to attend the City of Durham's City Council meeting and address that City Council. Mr. Wegner stated that he had already attended three different CIT meeting and would be attending a fourth meeting tonight. He has also contacted the City Administrators from bath King City and Durham and offered to them the opportunity to display the charts from MSA and make a presentation on the Water Supply Plan. Paul Hunt stated his concern regarding the bylaws for the Intergovernmental Water Board. While he was attending as the Alternate for John Schwartz he had suggested some changes to the bylaws in regards to the election process and since election time is nearing, he wanted to stress the importance of discussing this again. Mr. Wegner stated this would be on next months agenda. APPROVAL OF MINUTES The minutes of the September 14th. meeting were approved as written and approved unanimously. 7ISCQSSION OF WATER SUPPLY PLAN Mr. Wegner stated that he would like to bring everyone up to date on the discussion of the Water Supply Plan. On September 27th. the Tigard City Council adopted the Murray Smith Plan as the long term water supply plan for the Tigard water service area. It is currently being printed and the final copies will be distributed within the next two weeks. He stated that they have begun working on formulating the working plans as to how to approach this. On the second page of the memo it states that we are in the process of developing a newsletter with the hopes of changing this every other month to accommodate the billing cycle. This will hopefully begin with the November billing cycle and will discuss water activities. We have also begun negotiating with Murray Smith for a second contract that would provide us with engineering and consulting services as we proceed through the negotiations with Lake Oswego and Tualatin Valley for the interim period of time. Meetings have been held with the Director from Tualatin Valley Water District and Mike Miller has meet with the Chief Engineer to discuss the possibility of providing water for an interim period of time. Hopefully the second week of November, we will be invited to a meeting with Tualatin Valley to discuss the Willamette River. They have had an engineering study done on the Willamette and will be sharing it with interested communities. John Schwartz discussed briefly the past summer, the Wilsonville area being out of water. Mr. Wegner stated that they did initiate some water restrictions during the summer. Mr. Schwartz stated that it was his understanding that their reservoirs were so low they were not even able to maintain fire flows. It was stated that Wilsonville does have some water rights on the Willamette and they are one of the interested parties in a regional facility in that area. Some of the interested parties to this facility are: Tualatin Valley, Tigard, Tualatin, Wilsonville, and Sherwood. Mr. Schwartz stated the importance of talking with Lake Oswego but at the same time should be working with other communities also. Mr. Wegner stated that he would be attending a meeting on November 25th at Corvallis on the Willamette and the Water Quality Study that was done. Mr. Schwartz also questioned whether there would be a time table put together that would outline when negotiations and other issues will take place. Mr. Wegner stated that he would be putting together a work plan and timetable that he will be distributing within the next couple of weeks. Bill Scheiderich questioned whether Mr. Wegner or someone else on the Board could summarize the intent of the Water District Board and the City Council as to interim purchases of large volumes of water from IWB BOARD MEETING - OCTOBER 121 1994 PAGE 2 Portland. Mr. Wegner stated that if another source is available such as TVWD, for the large volume, we would like to check on those possibilities. Mr. Scheiderich stated that the City of Beaverton is beginning negotiations with Portland for an emergency water supply given that if the water main on Murray Road is ever severed they would be dependent upon reservoirs alone. For the interim there has been direction given to negotiate with Portland for emergency or backup water supply. There has been some discussion on obtaining that water from the Bradley Corner connection. There is a 1973 Agreement whereby, Tigard Water District and Metzger Water District both get 3 .65 mgd in that line with Beaverton having the right to construct a parallel line from Five Corners. There has also been some discussion with Beaverton connecting further from Bradley Corners to a connection with the Beaverton system and the Tigard Water District at approximately where Hwy 217 goes under Hall Boulevard. Chair Manning questioned whether Jack Polans had received a copy of the Water Supply Plan Update. Mr. Polans stated that he had not received a copy. Chair Manning questioned whether a copy of this could be provided to Mr. Polans. Mr. Wegner stated that at this time there is a copy available in the Library and we have no additional copies. Chair Manning stated that she would like to request a copy of behalf of Mr. Polans and if there was a cost issue, the City of Durham would pay for that. Mr. Wegner stated that there is also a copy available in each of the respective City Administrator's offices. Mr. Wegner stated that he had provided the Board with two months of Water Reports (August and September) . Discussed the issue of Water Quality which has been in the media lately. An article on taste and odor was in the Tigard times and also the television media has been running information on cryptosporidium. He has also included in the packets some information on the taste and odor problem from Gary Deadmond at the Water Treatment Plant. Mr. Wegner stated that these articles have also been provided for the Cityscape and also to the City of Durham and King City for their newsletters. Mr. Wegner stated that in the last six months the City has annexed fifty-six (56) acres of land and the Ordinance for withdrawal from the Tigard Water District will begin. Mr. Wegner's memo also addressed the water conservation coalition in this area of which Randy Volk is a member of. They have put together a school program that has distributed to all the area schools for the teachers use. Northwest Natural Gas program of shower conservation kits has distributed 3 , 222 conservation kits in the Tigard Service Area upon requests. This is about 1/4 of the customer base for the service area. All three cities have approved the Resolution adopting the Division of Assets Report and next week the Tigard Water District will have it on their agenda for approval. After approval by the TWD, we will have a final copy prepared and distributed to all the parties. IWB BOARD MEETING - OCTOBER 12, 1994 PAGE 3 Maintenance Services has moved the Vehicle Maintenance operation to the Water Building facility which were built and designed for vehicle maintenance. Tigard Water District had in the past contracted out all of the vehicle maintenance and we are currently doing that in house which will reflect a savings. Chair Manning discussed the mandatory notice for the lead and copper program, and questioned whether there have been many requests for sampling? Mike Miller stated that we have had a few requests, but not many. Mr. Wegner stated that there has been a lot of calls regarding the taste and odor problem. Mr. Wegner stated that this is the first month for combined billing on a regular cycle. A lot of residents in the Tigard Service Area received utility billings in excess of $100 for a two month period, which included water, sewer, and storm water charges. Mr. Wegner stated that the Finance Department is considering changing the billings to say City of Tigard Utility Bill versus City of Tigard Water Department. John Schwartz questioned what the average increase on sewer bills were since we have gone to the water consumption formula? Is this rate linked to water charge increases or sewer charges? Mr. Wegner stated he would check and find out the figures from USA. NEXT AGENDA ITEMS Bylaws discussion Long range water plan Mr. Wegner did mention that Mike Miller is on a Committee that is working with Portland and some other communities on model contracts.

The Board may want to have more flexibility if there"is-only one or two months left on a term. George iMorgan suggested to the Board that they look into this issue further since there are other appointments that would influence this position. The Board discussed whether the Board was in jeopardy in operating without a set of Bylaws. Paul Hunt discussed his concems with the following areas: The ability of the Chair not being able to be re-elected, determination of a persons qualifications being better determined when it is time to elect a Chair rather than a year in advance, due to appointment terms, you will be limiting the person who can be elected to this position, the conflict of terms expiring from City Councils and their effect on the Board, and also he questioned the annual date of the election and the members appointment to the Board. The Board decided to review this issue and concerns at the next available meeting.

Existing Long Term Capital Improvement Program Michael Miller, Water Management Analyst, reviewed for the Board, the current 5 year Capital Improvement Plan. He outlined the comprehensive plan developed to meet the water demands of the service area. He briefly discussed the objective of SDCs (System Development Charges) stating the income for SDCs comes from water meter installations. Approximately 60% of the water meter sales revenue is directed to the SDC Fund and the remaining 40% is deposited into the Water General Fund. Bill Scheiderich questioned Mike Miller about the amount charged for SDCs and how it compares to neighboring communities. Mike Miller responded that this should be re-examined within a year or two. George Morgan asked why there is a 60/40 split of the SDC revenue and whether or not an update is envisioned as the cost of business and installations increase. Mike Miller responded that the SDC methodology hasn't been changed since 1991 and this too is an area in need of future review. The Board continued to discuss with Mike Miller the area currently being served by the water department and its future needs as the area develops. Peggy Manning asked what other cities Lake Oswego provides water to. Mike Miller responded that the City of Tigard is Lake Oswego's main-,customer;.however also serves the Cities of Lake Grove, Rivergrove, portions of Portland and Tualatin. • George Morgan asked how the water department visualizes having the flexibility of meeting demands in light of the budget process; the need to establish rates and fees that might be applicable for new demands; and with the uncertainty of the capital improvement demands that might be modified referring to the presentation by Murray, Smith and Associates, Inc. and their inability to meet the time schedule. Ed Wegner responded that when the Water Supply Study Update by-Murray, Smith and _ Associates, Inc. is completed, the CIP will again be examined and updated to meet the necessary changes to reflect the recommendations for capital improvements for water source needs. Mike Miller explained that the CIP has been updated and altered to some degree every year since 1990 to better serve the changing needs,of the service area.

Pilot testing was conducted at Wilsonville,Oregon, approximately 40 miles upstream from the mouth of the Willamette River. PROJECT BACKGROUND This pilot study was conducted in the context of a larger regional water supply planning effort currently underway in the Portland metropolitan area. As a participant in regional supply planning, the District undertook the pilot study in order to develop cost and treatability information on this potential new source of drinking water. Concerns about immediate and long-term water supply needs in the District's rapidly growing service area provided the primary motivation for an evaluation of the Willamette River as a future source of supply 1 PROJECT OBJECTIVES F The primary objective of the Willamette River Water Treatment Pilot Study (WRWTPS) - was.to.identify an appropriate filtration process for Willamette River water In order to evaluate the numerous treatment processes and conditions tested during-the.pilot.study, stringent water quality and operational goals were developed before beginning pilot plant operations. The pilot study treatment goals were selected to: f meet all current federal and state drinking water regulations; (� a -produce water of high aesthetic quality with desirable taste, odor, and color � characteristics; • meet levels of regulated disinfection by-products anticipated in the year 2000; i -" • meet enhanced coagulation requirements under the anticipated ,Disinfectant/ Disinfection By-Product Rule,scheduled for promulgation in achieve greater than 3.5 logs (99.97 percent) of particle removal in the Giardia • and Cryptosporidium size ranges, to anticipation of Enhanced Surface Water i Treatment Rule requirements,scheduled for promulgation in 1996, • assure an efficient,cost-effective treatment process by meeting operating goals for i filter run length-and:filtered water production. I The treated water quality goals for this project were rigorous, in anticipation of more I complex and stringent federal drinking water regulations to come. Other considerations, such as the following,prompted the use of conservative treatment goals for this project. i i ES-1 EXECUTIVE SUMMARY • The Willamette River Basin supports multiple human activities including agriculture, forestry, industry and urban land use; the potential for contamination of the River must be recognized; • Where the Willamette has been used as a drinking water source, taste and odor episodes have been recorded, • Extensive water quality data on the Willamette River are lacking; • The District's consumers are accustomed to drinking water of high quality. To be acceptable to the consumer, treatment of the Willamette River must produce drinking water of equally high aesthetic quality Treatment designed to meet but not surpass existing standards may be perceived as unacceptable by District customers. For all of these reasons, a conservative treatment philosophy was adopted for the pilot study,on the assumption that the goal was excellence, not adequacy PROJECT APPROACH A state-of-the-art treatment approach was selected for this project, capable of producing water of the highest possible quality, while also being cost effective in comparison to other treatment approaches. This treatment philosophy can be described as a "multiple- barrier approach". To ensure the highest quality treated water, the following multiple barriers to chemical, physical, and microbiological contaminants were included as part of the treatment process: • Pre-oxidation with ozone was evaluated in the pilot study because of its powerful oxidation and disinfection abilities. Ozone has been demonstrated to be effective for the control of pathogens, disinfection by-products, tastes and odors, pesticides and.--metals. More.than40 ozone plants have been builtin the.United States(U.S,)._ y. since the 1970's, and an estimated 2,000 ozone plants are in operation world-wide ��. tprimarily in Europe): Ozone-is increasingly-living.applied ih.1he_U'S..as:utilities_ -respond to-changing drinking-water regulations and public demands for safe,pure �y water(Tate, 1991). , • following pre-oxidation, the coagulationtflocculation/sedimentation process was < teswd for removal of dissolved and particulate contaminants: This Serie$_ of o Y -processes is fundamental`to conventional water treatment and has been in use for -effective for the removal of naturally-1 1, decades. The sedimentation process is � . occurring organic matter and suspended silts and clays. It also assists in the 4g removal of contaminants such as heavy metals, pesticides, cysts, and viruses f (Montgomery, 1985). Fittration using granular activated carbon (GAC) filter media was-evaluated in the r=p 10 studstud Y� GAC media is commonly used in the U.S. for the removal Qf taste <' Pi and odor causing chemicals, synthetic organic chemicals, and naturally-occurring organic material which forms disinfection by-products. The filtration step is also s. the final barrier for the removal of microbial contaminants and dissolved and r i particulate material that affect water clarity and color 4 -= ES-2 M ` EXECUTIVE SUMMARY In practice,the final barrier in the multiple barrier approach is the use of a secondary, or distribution system residual disinfectant such as chlorine or chloramines. Secondary disinfection was not evaluated as part of the pilot study,although it would be practiced in any full-scale application. PROJECT RESULTS Five months of pilot testing were conducted to evaluate the ability of the processes described above to meet the project's water quality and operational goals. A successful treatment process was developed which includes pre-ozonation, coagulation/ flocculation/sedimentation using ferric chloride and canonic polymer, followed by filtration at a rate of 6 gallons per minute per square foot (gpm/sf) through a deep-bed GACIsand dual media. The optimized process produced excellent filtered water quality and filter run lengths which met operating goals. Levels of disinfection by-products in chlorinated filtered water were well below the regulatory limits anticipated in the year 2000. This treatment process was observed to be effective for the control of naturally- occurring earthy/musty odors in Willamette River water Should herbicides and pesticides ever be present, this treatment process will also provide barriers to the passage of these chemicals through the treatment plant through the combined action of oxidation, sedimentation and filtration. The major conclusions of the pilot study can be summarized as follows: • Historical water quality records, as well as data collected during the pilot study indicate that the Willamette River is a high-quality source water This water has lower levels of organic material than most surface water sources in the U.S. (as .measured-by total-organic carbon). Ten years of water quality data, collected by the Oregon Department of Environmental Quality (ODEQ) from 1982 to 1993, indicate that the Willamette could be classified as an unfiltered surface water supply for six months out of the year based on raw water turbidity. • A multiple-barrier treatment process can successfully treat Willamette:River water to meet stringentwater quality and operational goals. The technology used to treat this water ia'commonly-available to the U.S.-and can produce-drinking water` at costs comparable to other U.S. facilities. • Humanactivities in the Willamette River basin and the potential introduction.of - synthetic organic chemicals into-the river was a recognized issue in this study Available water quality data do not indicate detectable levels of pesticides or herbicides in the Willamette River mainstem A worst-case analysis of the presence of dioxin (a by-product of the Kraft pulp bleaching process) and atrazine (a commonly-used herbicide in the Willamette Basin) was conducted using the highest levels of these chemicals which had ever been found in water or sediment anywhere in the Willamette Basin, along with a host of conservative assumptions (see Section 10). The analysis shows that worst-case, chronically-occurring concentrations in the raw water would be expected to meet existing drinking water standards for dioxin and atrazine without filtration treatment. In addition, pilot testing demonstrated the ability of the multiple-barrier process to remove the spiked herbicide atrazine. The ability of ozone and GAC filtration to remove organic contaminants is well-documented. ES-3 EXECUTIVE SUMMARY Pilot testing and worst-case analyses have demonstrated the ability of the multiple-barrier treatment process to provide drinking water of excellent quality. All. available information suggests that this process will meet treatment goals over a wide range of water quality conditions. This conclusion can be assured by collecting more information on Willamette River water quality, particularly with respect to concentrations of previously-undetected synthetic organic chemicals. To this end, the District is undertaking a two-year Willamette River Raw Water Monitoring Program. This program will provide the most comprehensive picture of Willamette River water quality generated to date, and includes routine analysis for 164 organic chemicals in water and sediment, along with a host of other inorganic and microbiological indicators commonly used in drinking water treatment. If raw water monitoring detects the presence of specific chemicals or other water quality parameters at unacceptable levels, then the treatment process must be evaluated to assure its ability to remove them to safe levels. This pilot study indicates that further consideration of the Willamette River as a future drinking water source would be consistent with the Tualatin Valley Water District's and the region's goals and expectations with regard to public health,cost,and aesthetics. ES-4 R IiiterOtl'ice Memo To: Ed Wegner From: Michael Miller Date: November 30, 1994 Subject: Meeting with TVWD Yesterday, I met with Jesse Lowman of Tualatin Valley Water District (TVWD) along with Chris Uber and Hal Murray of Murray Smith&Associates(MSA)to discuss possible intertie locations and potential water supply availability from TVWD We discussed three possible locations: • Baylor Street Reservoir Site • Bradley Corner(SW Hall Blvd. and SW Greenburg Road) • SW Cascade Avenue At the. Baylor Street reservoir- -site- we currently have two, one million gallon .steel reservoirs with a 12-inch transmission main. 'Because these reservoirs are located at the extreme north end-of our service area they do not fluctuate with the system. Rather,these reservoirs stay fill during the summer high demand period. TVWD does have a 12-inch water main available at SW Baylor Street-and SW 68th Avenue which can be used to fill the reservoirs. If TVWD has excess capacity in their 498 foot zone (MSA will verify and examine the hydraulics involved in providing water to Baylor) we will connect to their 12-inch water main with a new 12-inch water main°and installa new master meter and pressure reducing r valve (PRV) station at the Baylor Stree�vt�,,reservoir site. Inn addition we will have to vn•>a.:ai<u5ar. 9x.�.-,a, ate and,�ze-thea�er� Pump �rin�Lllon in,,order-'tQ: �•-t�le�W�te&-�'Om'athe.'.a..a%- .e.v..,r,r .a Baylor Street reservoirs to our main operating zone. If the- water is available, this connection will yield 2.0 million gallons of water per day(M®)during the summer The Badley Comer.irrterfiie would be made`with-TVWD`s 24-inch water main from, the Washingto,County Supply Main that has,a hydraulic grade line of 426 feet: Our existing ., 16-inch transmission main-has a.hydraulic grade line of 644 feet. We currently-utilizefkill line pressure to drive water to the 10 million gallon reservoir Because of the pressure _ differences, and if water is available; we may need to install a pump station in order to " boost the water pressure to equal the head pressure of the Portland supply. Since the Bradley Comer connection is also our connection with Portland, we will need�the ability to import Bull Run water simultaneously, especially at times when TVWD-cannot supply full volume. One of the improvements that will be necessary in the TVWD service area is that the 10- inch master meter for TVWD will need to be enlarged to 16-inches. By enlarging this meter, TVWD will eliminate a flow restriction in their transmission main and allow more water to be .supplied to the Tigard Service Area. The amount of water available from Meeting with TVWD 11/30/94 Page 2 TVWD at this. location..is..not .known at this time, we believe that 3 0 MGD maybe - - . :,.ava{laisle :andl*n will`be ptovided by TVWD. One of the conemwisIthe-effeathat-this connection-may have upon the City of Tualatin and their ability to supply their City from the Washington County Supply Main The final connection location is at SW Cascade Avenue, where we already have a non metered intertie. This is an 8-mch imertie that may provide up to approximately 1.0 MGD from TVWD's 426 hydraulic grade line. Even though this would be connected to our 410 zone, and if the water is available, all we would need to do is install an 8-inch master meter,control valve(pressure sustaining valve) and vault. We would not reduce TVWD's line pressure. The Water Division has already begun preparing for the possible Baylor Street connection with TVWD We have cut-in afire hydrant on our existing 12-inch transmission main to allow us to flush the main in two directions. Also, we are having a local electrical contractor inspect and ensure that the Hunziker pump station is operational: This pumping facility has not been operated or exercised in the last 12 to 15 years. It is important to state that the fire hydrant installation and the inspection of the Hurinker pump station needed to be completed even if TVWD cannot supply water to the Baylor Street reservoir site. The ability to utilize this pumping facility is part of our-summer supply plan, because as I had stated in the beginning of this memo, the Baylor Street reservoirs remain full due to the distance from the nearest connection and lack of use even though the rest of the 410 zone is low during the summer months. ff all three connectionsarebrought on line by next summer, TVWD maybe able to supply — -- __ =-us 6.0-MGD This is the amount of water that they have informally'indicated is available and they will have to perform fiurther analysis to verify the exact amount of surplus water that would be available to our service area.

GLICKER EDUCATION: M.S. Biochemistry, University of Illinois B.S. Engineering Mechanics, University of Illinois REGISTRATION: Professional Engineer,Chemical Engineering in Oregon SUMMARY: Mr. Glicker has over twenty years of experience in water and wastewater treatment, municipal utility management, water quality, water resources, watershed management, groundwater management, capital improvements planning, and water legislation and regulation. Mr. Glicker joined Montgomery Watson in 1994 as a Principal Engineer. For fourteen years he was with the Portland Water Bureau serving most recently as Chief Engineer, after having served as Director of Water Quality and Environmental Policy. RELATED EXPERIENCE: Mr. Glicker was one of five persons representing the water supply community on the U.S. Environmental Protection Agency Federal Advisory Committee which negotiated the upcoming Enhanced Surface Water Treatment Rule, Disinfectant/Disinfection Byproducts Rule and Information Collection Rule. Mr. Glicker was a member of the AWWA Technical Advisory Workgroup which developed the issues and positions that the water supply community is taking concerning reauthorization of the Safe Drinking Water Act (SDWA). These concepts were developed into the legislation which is currently being discussed in Congress and may pass this year. Mr. Glicker continues to advise AWWA and the Association of Metropolitan Water Agencies on SDWA reauthorization issues as they are debated in Congress. Working at the Portland Water Bureau, Mr. Glicker was Principal-in-Charge of a three year $2.5 million Water Treatment Pilot Study which looked at ozone, chlorine and chloramine disinfection of Giardia and viruses and at ozone/filtration studies for optimal treatment for microbial and disinfectant byproducts removal. He was also a member of the Technical Review Committee for an AWWA Research Foundation project on the removal of Giardia and Cryptosporidium in the filtration process. Mr. Glicker is an expert on watershed mangement for water supply sources. He was principal investigator for development of a guidance manual for water utilities on establishing practical watershed management programs. He also was responsible for the Portland Water Bureau's watershed management program for over 10 years. This program is a nationally recognized example of effective watershed management. He has also been active in administrative and legislative issues on water conservation, watershed management, water rights, and other water resources issues. JOSEPH L. GLICKER (Continued) Working with the Portland Water Bureau, Mr. Glicker was responsible for developing, designing, and implementing public involvement and information programs on water quality, water treatment and watershed management issues. He managed an ongoing citizen Water Quality Advisory Committee. He worked with the public involvement staff to develop public information pieces, design customer surveys and conduct public involvement workshops. He was media spokesperson on many utility issues, including those relating to difficult explanations of potential contaminants in the water supply. As Chief Engineer, Mr. Glicker managed a large professional and support staff responsible for all aspects of engineering, design, water supply, capital improvements, and system operations. He managed a yearly capital program of over $10,000,000 that included complex water treatment, pipeline, pump station, and other water system projects. Mr. Glicker has been responsible for oversight of the effort to recover use of a groundwater source after groundwater contamination was discovered near the Portland wellfield. He was responsible for negotiations with Oregon Department of Environmental Quality and EPA to obtain their approval to use the wells by demonstrating that the groundwater resource would be protected despite the presence of contaminants near the wellfield. Mr. Glicker led the City of Portland effort to establish a Groundwater Protection Area for its wellfield. At the time it was established in the mid-1980's, prior to discovery of contaminants near the wells, it was the first protection area in Oregon. Mr. Glicker also has six years experience in the design and operation of industrial water and wastewater treatment facilities. He worked both for an engineering consulting firm, and an operating company designing, constructing and operating water and wastewater treatment plants.
