Board Members Present: Chair Scheiderich, Commissioners Froude, Hunt, Manning, and Budihas Staff Present: Bill Monahan, han, Ed Wegner, Wayne Lowry, Mike Miller, and Kathy Kaatz Visitors Present: Jack Polans, Norman Penner, Lou Ane Mortensen 1. Call to Order The meeting of the Intergovernmental Water Board was called to order at 5:36 p.m. 2. Roll Call Roll was taken with all members present. Visitors present included Jack Polans and Steve Feldman. 3 . Visitor Comments Jack Polans stated that he would speak only briefly since he was interested in the presentation to be made. Mr. Polans stated that he had been spending time attending meetings at the City of Lake Oswego in an attempt to gain information regarding the negotiations between the City of Lake Oswego and the City of Tigard. 4. Approval of Minutes Motion was made by Commissioner Hunt to approve the minutes of the April 19, 1995 meeting minutes which was seconded by Commissioner Manning. A voice vote was taken which passed unanimously. S. RFP - Water Rate Study Presentations Chair Scheiderich stated that Mr. Lowry would be introducing the presenters and then the presenters will be able to elaborate on the introduction. Mr. Lowry stated that the RFP asked for proposal on a water rate study with the scope of work containing the following: a. Develop revenue requirements for a five year period. b. Develop cost of service analyst based on customer classifications. C. Develop a cash flow computer model that would be left with the City for use in the future as we would plan capital improvements. d. Update System Development charges. Mr. Lowry stated that with this scope of work there were five proposals all of which were included. in the Commissioner's packets. Mr. Wegner, Mr. Lowry and Mary Gruss evaluated these proposals and arrived at the three finalists that are present tonight. Mr. Lowry stated that after their presentations are heard, it is suggested that the Board make a recommendation to the Tigard City Council for their meeting in June. The three presenters present at the meeting tonight are: CH2M HILL, EES and David Griffith and Associates. CH2M HILL CH2M Hill was the first presenter. David Hasson is the proposed project manager for this project. Mr. Hasson introduced Debbie Davis, a rate economist and Bob Fuller, a Senior Water System Engineer. After their presentation, Commissioner Hunt discussed the challenge of selling the public on the need for a new water supply. Mr. Hasson stated that this would not be the main thrust of this study although the study will relate to the cost numbers and what alternatives are in relation to the need. Commissioner Budihas questioned the ability of CH2M Hill meeting the schedule and budget needs. Mr. Hasson stated that CH2M Hill makes every effort to stay within budget constraints. Mr. Hasson stated that the only time that additional charges would be the responsibility of the City would be if the City asks for something beyond the scope of the Contract. Commissioner Manning questioned the length of the study with the dynamics of the need for long term water supplier? Mr. Wegner stated that it is the assumption of staff that the model will allow us to plug in capital improvement figures and modify those. Mr. Hasson stated that during the study they will identify the option that will be used and should that change during the course of the study or after the study, these figures can be changed and will reflect what that will do to the rates. Commissioner Manning discussed that this firm would not be doing the marketing of a bond or a debt service that will need to be sold to the public. Intergovernmental Water Board - May 17, 1995 Page 2 Chair Scheiderich questioned what type of input has been provided for in the proposal in regards to the fairness issue? Will a window be placed out there for the public bodies to suggest a equitable issues to be considered? Mr. Hasson stated that the first steps that would be undertaken to address fairness would be to identify what it meant by the word fair? In the kick off meetings, CH2M Hill would determine what is fair and see what can be met simultaneously and proceed. Mr. Hasson stated that these conclusions would be determined by a consensus from the Board. Mr. Scheiderich questioned to what extent there is room in the study to do a comparison of how other local water providers have faired by way of matching their financial plans to their success or failure? Mr. Hasson stated that they can provide antidotal types of evidence of others in the area. Mr. Hasson stated that if something more of a survey is required, it has not been figured into the budget, but could be provided if wanted. Mr. Scheiderich questioned whether they were confident that enough time has been budgeted to consider questions not answered in the draft? Mr. Hasson stated that these time frames have been figured in within reason. Mr. Scheiderich questioned the computer model that will be developed and the ability to run on standard software? Mr. Hasson stated that this would be ran on Excel. Mr. Scheiderich also questioned whether the payment schedule is keyed to deliverables or hourly billings? Mr. Hasson stated that it negotiable. Mr. Polans asked the Board if he could questioned the presenter? Chair Scheiderich stated that Mr. Polans could reserve his questions until after all the proposals were heard the Board may invite comments and questions. DAVID GRIFFITH AND ASSOCIATES Mr. Lowry introduced David Griffith and Associates. Bob Chandler the Pacific Northwest Manager, and Bob Reed out of their Sacramento office who is a specialist in water rate studies were introduced. After their presentation, the Board had the following questions and discussions. Commissioner Froude questioned whether conservation would be addressed for this rate structure? Mr. Reed stated that initially it is important to understand the rate setting objectives or policy objectives that relate to the water Intergovernmental Water Board - May 17, 1995 Page 3 rates. If conservation is an objective than it is important that the rate structure encourages conservation (tiered rates, commodity component of rate which is the based upon the volume of water being used versus a monthly service budget) . Commissioner Manning questioned what effect different scenarios would have on these policies? Mr. Reed stated that their firm is known for conducting policy workshops with either a city council, board of directors or citizens advisory committees which are organized just for the purpose of doing the rate study. Mr. Reed stated that they would like to have a policy workshop to explain the rate setting process and the issues that need to be addressed as a part of the rate study. Mr. Reed stated that they would also need at the end of the study to identify the number of meetings and presentations to present the results of the study. Commissioner Manning questioned whether the Board has the time frame to do this education? Mr. Wegner stated that the time frame is flexible. Mr. Reed stated that additional meetings are not built in to do education process. The total number of meetings included were six. The RFP included an initial meeting, monthly reports to staff, public hearing in front of IWB and the four other entities involved. Commissioner Hunt discussed the current billing cycle being every other month and the discussions on whether this should be changed to monthly. Will the results of this study help in making that decision? Mr. Reed stated that they can looked into what will be involved. Mr. Reed continued to say that from a cost standpoint, monthly billings would only be valuable for the large use customers. He continued to discuss the possibility of estimating bills also. Mr. Scheiderich questioned to what extent within the scope of work would they compare the approach to be taken with other local water providers (comparison among local providers) ? Mr. Reed stated that they would be willing to do a survey of a few neighboring communities. Mr. Reed continued to say that they would obtain copies of their rate schedules and the SDC' s that they have and show monthly bills in a comparison format. Mr. Scheiderich questioned whether they would be prepared to show projection has fulfilled itself in other entities? Mr. Reed stated that in terms of the five year projection of what rates should be, he would be concerned about making projections since there are a lot of variables. Intergovernmental Water Board - May 17, 1995 Page 4 ECONOMIC AND ENGINEERING SERVICES Mr. Lowry introduced the firm of EES. Randy Goff began the presentation by introducing himself as the Vice President of EES out of the Portland office. He then introduced Tom Gould, Vice President out of the Bellvue office. After finishing their presentation, Commissioner Hunt questioned the computer model being a requirement of the RFP. Mr. Goff stated that the model would be included in the study and the documentation. They stated they will also be here in the future if additional assistance is required in the future. The Board took at break and resume the meeting at 6:58 p.m. 6. Discussions and Recommendations on RFP Ed Wegner stated that after hearing the three presentations that the Board heard and reviewing all the documents and with the familiarity of various consultants within this system, the staff would recommend the use of Economic and Engineering Systems. Chair Manning questioned what factors this recommendations was based upon? Mr. Wegner stated that all the companies represented made contact with his office when picking up the RFPs. EES asked questions that were based upon what the City wanted that would be beyond the scope. Mr. Wegner stated that our, RFP was based upon what was picked up from Tualatin Valley, Beaverton, Hillsboro and EES is the consultant of record for two out of three of these agencies. Also the City has worked with Mr. Goff on the Division of Assets. Mr. Lowry stated that it was his opinion that CH2M Hill would do their study like they have done 200 others. EES has a lot of local experience with other agencies that we would want to be compared with. EES has a slightly higher cost but, the foundation of this study is vital to the next five years of the Tigard water system. Commissioner Manning questioned whether there was any independent referencing to other communities and municipalities that these presenters have worked with? Mr. Lowry stated that he has talked with Rob Masters, City of Hillsboro and discussed the rate work and they were very pleased with EES. Mr. Wegner stated that Tualatin Valley also has a very high regard for EES for work on projects they have had. Intergovernmental Water Board - May 17, 1995 Page 5 Commissioner Manning questioned when they worked for, Tualatin Valley Water District other than doing the division of assets? .Mike Miller stated that they worked for them in 1989 or 1990 . Mr. Miller also stated that the SDC' s are outdated and need to be updated. Mr. Wegner stated that EES has been the engineer of record for the Tigard Water District for years. While EES was working on the Division of Assets, Randy Goff had stated at that time that the SDC' s needed to be updated. Mr. Miller stated that Mr. Meigs (EES) has been working with the District since 1973 . Commissioner Manning stated after reviewing the proposals, in her opinion EES came in third as far as personalization. Ms. Manning felt that the other two presenters were quite anxious to educate the Board on setting the parameters on policies. Commissioner Budihas stated that the first presenters agreed to have four separate meetings and EES did not mention meetings with Council or the public. Chair Scheiderich stated that these meetings were called for in the RFP. According to Ms. Manning on page 19 of EES' s proposal the meeting schedule was mentioned. Chair Scheiderich stated that instead of a motion he proposed that the Board just go person by person and state what is on their mind. Commissioner Hunt stated that: • CH2M Hill bid came in at two thirds of the other bids which caused concern. • DMG (David Griffith and Associates) did not care for presentation and if results would be comparable to presentation it would not be good. 0 EES - would be the choice of the three. Was, bothered slightly since presentation at the end of the Division of Assets was not good. Gil Meigs who did that presentation is not a part of the team to work on this RFP. Commissioner Manning stated that: s CH2M Hill - all three project managers were here and all local . CH2M Hill have worked with DEQ and are very professional, flexible. • DMG - Emphasize interacting with community. • EES - Did not emphasize the interaction possibly since they already have a basis of knowledge. Intergovernmental Water Board - May 17, 1995 Page 6 Commissioner Froude stated that: • EES or DMG either firm would be good. Did not ask the questions of EES that were asked of the other presenters which opened up their presentations. Commissioner Budihas stated that: • This is a big project and would be best dealt with by local people. • CH2M Hill are all local, very professional, have good reputation. • EES - only one person here full time, part of project team will only be working on the project part time. Chair Scheiderich stated that: • EES had the most thorough written presentation. • CH2M Hill product would be the equivalent. • DMG - not convinced that they understand SDC' s charges. • CH2M Hill as well as EES have done work for City of Beaverton with CH2M Hill being more sensitive at the outset to hearing the social issues. • CH2M Hill put it's bid in terms of deliverables and their own schedule sets up the ease with which a contract can be negotiated. • Scope of work is scheduled according to points where a product is deliverable. EES points out time and materials. • CH2M Hill computer model is deliverable on over the. counter software. • Placed CH2M Hill first with EES a close second. Mr. Wegner stated that all presenters will be providing the computer model on over the counter software. Commissioner Hunt ran a service for utility billing and the majority in the area did use CH2M Hill and he has never heard a complaint. Chair Scheiderich stated that with discussion over, he requested a motion. Mr. Monahan stated that this motion would be for recommendation. Mr. Scheiderich stated that this motion would be to recommend a particular consultant. Commissioner Manning made a motion to recommend to the Tigard City Council that the proposal be let to CH2M Hill and the second choice being Economic and Engineering Services and Company. This motion was seconded by Commissioner Budihas. A voice vote was taken with the motion passing four to one. Froude abstaining. Intergovernmental Water Board - May 17, 1995 Page 7 8. Regional Water Supply Slide Show Mr. Wegner stated that there is a slide show within each of the three participating counties in the Regional Water Supply Plan. The purpose being to bring all participants up to date on the supply plan. They will be distributing a draft of the plan within the next few months with some scenarios to look over. The City Council will make a recommendation along with the other twenty-six participants with a final draft being completed by December. As a part of the public involvement we will be using this slide show in September for the CIT's and if King City or Durham is interested we will also do that. Mr. Wegner showed the slide show (outline included in packet) . Mr. Wegner stated that the Participants will be meeting again on Tuesday where they will begin to put together the what if scenarios to bring this project to a final first rough draft. Mr. Wegner stated that he has all the draft documents that are done to date. The next meeting for the IWB was set for the June meeting on June 14, 1995. 9 . Adjournment The meeting of the Intergovernmental Water Board was adjourned at 7:55 p.m. kathyUwbX5-17mtg.min Intergovernmental Water Board - May 17, 1995 Page 8 f✓ Interoffice Memo To: Ed Wegner From: Mike Miller Date: June 6, 1995 Subject: June 2, 1995 Oregonian Article On Friday, June 2, 1995, The Oregonian published an article on the Natural Resources Defense Council (NRDC) briefing paper that discussed their findings about the chemical make-up of water in 100 community water systems across the country. In addition to the article, the Oregonian published an "In Oregon" section. In this section Tigard was identified as being one of three water service agencies, serving a population base larger than 10,000, that had the most violations. The Oregonian article does not identify the standards that were violated. The article in the Oregonian states: "There is widespread violation of'EPA's drinking water health standards and testing requirements, while enforcement is rare. The Safe Drinking Water Act and the source water provisions of the Clean Water Act need strengthening. Adequate funding is needed to restructure or upgrade water systems and to assure safe drinking water now and in the future. In Oregon, 1,492,000 people served by 729 community water systems have violated one or more health standards, treatment techniques, and monitoring and reporting requirements. In Oregon, there have been a total of 3,079 community water system violations". The article does not identify, nor does the NRDC briefing paper, what standards were violated. The article also does not state how or where EPA enforcement efforts might be improved. The City of Tigard makes every effort. to comply with regulations and supports research efforts that identifies compliance activities that meet the intent of the law as well as give our customers good return for their rate dollar. After reviewing the Oregonian article, I contacted Mr. Dave Leland, Manager of the Oregon Health Division's Drinking Water Program, and found that the only violation that Tigard had was due to some confusion with the population base of our service area. The confusion occurred in December 1994, when the Health Division records indicated that our population base was higher than what we were reporting. The number of monthly routine water samples is determined by population. Because of the confusion, we came up two samples short for the month of December. This was technically a violation of the Safe Drinking Water Act, but was very minor, and was nothing more than a clerical error. We collected additional samples in January and have since adjusted the total number of samples to be taken each month based on the Health Divisions population base for our service area. Mr. Leland stated that minor violations, such as this one in our service area, are reported in a data base to the EPA. The data base does not distinguish between the severity of the r.' f June 2, 1995 Oregonian Article 06/06/95 Page 2 violations nor does it contain remarks about the violation. It is simply raw data. This is the same data the NRDC based its report on. In no way does the violation indicate that the quality of our drinking water failed to meet Safe Drinking Water Act standards.

DEADMOND, CHIEF WATER PLANT OPERATOR DATE: September 28, 1994 RE: CRYPTOSPORIDIUM WHAT IS CRYPTOSPORIDIUM? Cryptosporidium (crypto, meaning hidden and spore, meaning seed or germ) is a parasitic protozoon that survives well in cold water and forms a cyst (known as oocyst) in adverse conditions. It is similar to&rdia (beaver fever), microsporidium, and cyclosporca. These organisms can commonly be found in lakes and rivers. WHY IS IT DIFFICULT TO KEEP OUT OF WATER SUPPLIES? The cryptosporidium cyst is very resistant to disinfection by chlorine. It has reportedly resisted chlorine several times stronger than the normal dosage used in water treatment plants for several hours. WIiAT IS ITS.HISTORY AND HOW SERIOUS IS IT? Cryptosporidium was first identified by a veterinary scientist in 1974 as the organism causing gastroenteritis in a Tennessee farm girl named Regina Gibbs. Later outbreaks of cryptosporidiosis include San Antonio (1984, 2000 ill), Carrollton Ga. (1987, 13,000 ill), Jackson County, Ore. (1992, 15,000 ill) and Milwaukee, Wis. (1993, 370,000 ill). In the last mentioned outbreak several people died. People most susceptible include those infected with AIDS and cancer patients undergoing chemotherapy. Symptoms include diarrhea and vomiting lasting for up to a month in healthy individuals. Some women sufferers have developed antibodies that attack their own blood platelets causing serious bleeding disorders. Obviously cryptosporidiosis is a more serious disease than the better known giardiasis. HOW CAN THE PUBLIC BE PROTECTED? The cysts can be removed by good filtration. The outbreaks in Carrollton, Ga. and Milwaukee, Wis. are of interest to us because both were caused by filtration plants that allowed the cysts to pass through the filters into the distribution system. Given that the cysts are very resistant to disinfection by chlorine, good filtration is the primary protection against disease outbreaks of this type. In the Carrollton, Ga. plant, for example, the combined filter effluent met all federal turbidity standards, but because monitoring of individual filters is not required it was not discovered that one filter was not operating efficiently. That filter allowed enough . cryptosporidium cysts through to contaminate the finished water without violating the federal turbidity standard. LAKE OSWEGO FILTRATION PLANT PREVENTION STRATEGY What is done at the Lake Oswego filtration plant to keep cryptosporidium and other protozoa cysts out of the treated water? • Each filter is fitted with its own turbidimeter. Each filters effiuent turbidity is prominently displayed on the filter backwash control board and recorded in the computer. High turbidities produce an alarm. A record of each filter's performance for the past day, week, or month can be printed from the computer for examination. • Plant"target" for turbidity is less than 0.1 NTU as opposed to 0.5 NTU required by federal standards. • "Filter to waste" operation is required when filters are not producing at least 0.3 turbidity. This can happen during the short 'conditioning' period just after a backwashed filter is returned to service. • A Streaming Current Monitor controls coagulant dosage to optimize floc size for filtration. WHAT ELSE CAN BE DONE? A particle counter will be purchased to monitor particle numbers and sizes in filter effluents. Particular attention will be paid to inhibiting passage of particles the size of protozoa cysts through the filters. DOES LAKE OSWEGO TEST FOR CRYPTOSPORIDIUM? Not at present. We have contacted Nielson Research in Medford about testing for giardia and cryptosporidium. We will be required by law to test every other month for eighteen months beginning October 1995. Each test requires filtration of 1000 to 1800 gallons of water, mailing the filter to Medford and a fee of$389.00. The required tests will be mainly for EPA research purposes. 'Because protozoa cysts are so widely interspersed in raw and much more so in finished water a negative test does not necessarily prove that no organisms exist. The best protection is to maintain good filtration techniques. CONCLUSION No water treatment facility can guarantee that a water borne disease outbreak will not occur. What it can do is do the best job possible by keeping abreast of current technology, maintaining operator training at a high level, and keeping equipment operating at peak efficiency. The staff at the Lake Oswego Water Drinking Water Plant is dedicated to doing just that. MANDATORY NOTICE FOR LEAD AND COPPER SAMPLING The United States Environmental Protection Agency (EPA) and the City of Tigard are concerned about lead in your drinking water. Although most homes have very low levels of lead in their drinking water, some homes in the community have lead levels above the EPA action level of 15 parts per billion (ppb), or 0.015 milligrams of lead per liter of water(mb/L). Under federal law, the City of Tigard is required to have a program in place to minimize lead in your drinking water by July 1, 1999. This program includes corrosion control treatment, source water treatment, and public education. If you have any questions about how we are carrying out the requirements of lead regulation,please call the City of Tigard Water Department at 639-1554. This article explains the simple steps you can take to protect you and your family by reducing your exposure to lead in drinking water. HEALTH EFFECTS OF LEAD Lead is a common, natural, and often useful metal found throughout the environment in lead4xtsed paint, air, soil, household dust,food,certain types of pottery,porcelain,pewter and water. Lead can pose a significant risk to your health if too much of it enters your body. Lead builds up in the body over many years and can cause damage to the brain, red blood cells and kidneys. The greatest risk is to young children and pregnant women. Amounts of lead that won't hurt adults can slow down normal mental and physical development of growing bodies. In addition, a child at play often comes into contact with sources of lead contamination-like dirt and dust-that rarely affect an adult. It is important to wash children's hands and toys often,and to try to make sure they only put food in their mouths. LEAD IN DRINKING WATER Lead in drinking water, although rarely the sole cause of lead poisoning,can significantly increase a person's total lead exposure,particularly the exposure of infants who drink baby formulas and concentrated juices that are mixed with water. The EPA estimates that drinking water can make up 20 percent or more of a person's total exposure to lead. Lead is unusual among drinking water contaminants in that it seldom occurs naturally in water supplies like rivers and lakes. Lead enters drinking water primarily as a result of the corrosion, or wearing away, of materials containing lead in the water distribution system and household plumbing. These materials include lead-based solder used to join copper pipe, and brass and chrome plated brass faucets.. In 1986, Congress banned the use of lead solder containing greater than 0.2%lead, and restricted the lead content of faucets, pipes and other plumbing materials to 8.0%. When water stands in lead pipes or plumbing systems containing lead for several hours or more, the lead may dissolve into your drinking water. This means the first water drawn from the tap in the morning, or later in the afternoon after returning from work or school,can contain fairly high levels of lead. STEPS YOU CAN TAKE IN THE HOME TO REDUCE EXPOSURE TO LEAD IN DRINKING WATER Despite our best efforts mentioned earlier to control water corrosivity and remove lead from the water supply, lead levels in some homes or buildings can be high. To find out whether you need to take action in your own home, have your drinking water tested to determine if it contains excessive concentrations of lead. Testing the water is essential because you cannot see, taste, or smell lead in drinking water. Some local laboratories that can provide this service are listed at the end of this article. For more information on having your water tested, please call the City of Tigard at 639-1554. If a water test indicates that the drinking water drawn from a tap in your home contains lead above 15 ppb, then you should take the following precautions: • Let the water run from the tap before using it for drinking or cooking any time the water in a faucet has gone unused for more than six hours.. The longer water resides in your home's plumbing the more lead it may contain. Flushing the tap means running the cold water faucet until the water gets noticeably colder, usually about 15-30 seconds. Although toilet flushing or showering flushes water through a portion of your home's plumbing system,you still need to flush the water in each faucet before using it for drinking or cooking. • Flushing tap water is a simple and inexpensive measure you can take to protect your'family's health. It usually uses less than one or two gallons of water and costs less than$.20 per month. To conserve water,fill a couple of bottles for drinking water atter flushing the tap,and whenever possible use the first flush water to wash the dishes or water the plants. • If you live in a high-rise building,letting the water flow before using it may not work to lessen your risk from lead. The plumbing systems have more, and sometimes larger pipes than smaller buildings. Ask your landlord for help in locating the source of the lead and for advice on reducing the lead level. • Try not to cook with, or drink water from the hot water tap. Hot water can dissolve more lead more quickly than cold water. If you need hot water,draw water from the cold tap and heat it on the stove. • Remove loose lead solder and debris from the plumbing materials installed in newly constructed homes, or homes in which the plumbing has recently been replaced,by removing the faucet strainers from all taps and running the water from 3 to 5 minutes. Thereafter, periodically remove the strainers and flush out any debris that has accumulated over time. • If your copper pipes are joined with lead solder that has been installed illegally since it was banned in Oregon in July 1985,notify the plumber who did the work and request that he or she replace the lead solder with lead- free solder. Lead solder looks dull gray, and when scratched with a key looks shiny. In addition, notify the Oregon State Health Division about the violation. • Have an electrician check your wiring. If grounding wires from the elecurcal system are attached to your pipes, corrosion may be greater. Check with a licensed electrician or your local electrical code to determine if your wiring can be grounded elsewhere. DO NOT attempt to change the wiring yourself because improper grounding can cause electrical shock and fire hazards. The steps described above will reduce the lead concentrations in your drinking water. However, if a water test indicates that the drinking water coming from your tap contains lead concentrations in excess of 15 ppb after flushing, or after we have completed our actions to minimize lead levels, then you may want to take the following additional measures: • Purchase or lease a home treatment device. Home treatment devices are limited in that each unit treats only the water that flows from the faucet to which it is connected,and all the devices require periodic maintenance and replacement. Devices such as reverse osmosis systems or distillers can effectively remove lead from your drinking water. Some activated carbon filters may reduce lead levels at the tap, however all lead reduction claims should be investigated. Be sure to check the actual performance of a specific home treatment device before and after installing the unit. • Purchase bottled water for drinking and cooking. You can consult a variety of sources for additional information. Your family doctor or pediatrician can perform a blood test for lead and provide you with information about the health effects of lead. State and local government agencies that can be contacted include: 1. The City of Tigard Water Department.at 639-1554 can provide you with information about your community's water supply,and a list of local laboratories that have been certified by EPA for testing water quality. 2. The City of Tigard Plumbing Section at 639-4171 can provide you with information about building permit records that should contain the names of plumbing contractors that plumbed your home. 3. The Oregon State Health Division at 731-4317, and the Washington County Health Division at 648-8881 can provide you with information about the health effects of lead and how you can have your child's blood tested. Following are some State approved laboratories in the Portland metropolitan area that you can call to have your water tested for lead: Coffee Laboratories,Inc.

A receipt is enclosed here unless you were previously issued one. Your application has been assigned the above referenced file number. Please refer to this number whenever you contact us about your application. Even though your application has been received, filed and assigned an application reference number, no authorization has been granted to develop your water use. The filing of an application does not create a water right. Water may not be used until a water.right permit has been issued by the Department. After an application has been accepted for filing, public notification of the application is made, followed by the mandatory 30-day comment period. Thereafter, applications can be considered for processing as time allows. At present the Water Resources Department has a backlog of several thousand applications for water use permits which has delayed our application processing time. In general, applications are processed in the order in which they are received. However, Department staff work through Oregon's 18 river basins on a rotation basis often completing work on all applications within a single basin, then proceeding to the next basin. The processing of an application does not guarantee that a water right permit will be issued. Each application must undergo specialized analysis called a technical review and a public interest review. Until your application is reviewed, it is not possible to determine whether your particular proposed water use will be recommended for a permit. The Water Resources Commission is considering the adoption of rules to protect stream flows for fish species. This action is being contemplated in response to current and future Endangered Species Act fish listings, including many runs of salmon, steelhead and resident fish throughout the state.

File(s) - S-80342 The proposed rules, if adopted, could limit the issuance of new water right permits in certain areas of the state. If and when the Commission adopts these rules, new criteria or restrictions may be imposed on water use applications received after: July 17, 1992, for use of water in the Upper Columbia/Snake Basin (above Bonneville Dam),including the mainstem Columbia and Snake Rivers and the Hood, Deschutes, John Day, Umatilla, Grande Ronde, Powder, Malheur and Owyhee Basins; April 8, 1994, for use of water in the North Coast, Mid Coast, South Coast, Rogue and Umpqua Basins and the Clackamas Subbasin of the Willamette Basin; and June 3, 1994, for use of water in all Oregon basins. When the report on the technical review is completed and sent to you, a 60-day objection period begins during which you, the applicant, or anyone who has expressed an interest in your proposed water use may communicate to us their disagreement with what we have said in our report on your application. After the 60-day objection period, the Department conducts the public interest review and considers any objections which have been made. After any objections have been considered, there may follow time to allow parties to resolve conflicts over the proposed water use. In addition, a 30-day protest period may be required. Lastly, it may be necessary to schedule a hearing or send the application to the Water Resources Commission for their review. If your application is recommended for approval and a permit is issued, the use allowed by the permit will be subject to the Basin Program Rules of the Water Resources Commission, instream flow requirements, the demands of prior right holders and other conditions to conform the water use to particular standards.

Eleanor Clark CRRELO,League of Women Voters Metro Regional Water Supply Proposal Process: Greg Nokes The Oregonian Lorna Stickel reviewed the progress report for the Jack Polaris self-writer Participants Committee(see Attachment A).Lorna Don Roberts discussed the framework of the water supply plan and Pegg_y Murphy Portland WB how elements of it might be used by the METRO Council as part of their 2040 Region project.Rosemary Furfey,METRO staff, reported that METRO expects to participate in the planning process for the next 9 months so their Council will be committed and educated about the final plan.METRO expects to use the portions of the Regional Water Supply Plan relating to growth management and land use as they develop the water Participants Committee Meeting March 28, 1995 Page 2 resource element of the Regional Framework Plan. The METRO Council is required to hold public hearings for this process. Rosemary anticipates the council will accept the plan. She said open space and housing density were important as they might affect the ability of water providers to site facilities. (See Attachment B.) Lorna referred to the METRO Council's proposed revisions to the Regional Urban Growth Goals and Objectives(RUGGOs). Goal No 9, regarding Watershed Management and Regional Water Quality has been revised since the Committee last reviewed it. Goal No. 10, Water Supply, is a new goal with corresponding objectives. Lorna said to contact Lorna or Rosemary Furley if there are questions.Rosemary offered to give a presentation on the RUGGOs to the Participants Committee. Lorna is on the MTAC and is responsible for taking concerns and providing input to METRO. Amendments to the RUGGOs will be decided in July. Public Involvement Strategy Update: Lorna reviewed the public involvement strategy update prepared by Brad Ifigbee(see Attachment C). It incorporates comments from the participants Public Involvement Subcommittee. The Portland Water Bureau is preparing a project information sheet, designed for the lay person. The Oak Lodge Water District is revising Portland's "Million Thanks"brochure to a generic version so it can be used as an information piece by any of the participants. Tom Hoffman expressed concern over developing a master mailing list based on the returned coupons from the "million thanks" brochure. Loma suggested that participants keep track of who they send the information sheet to and who is interested in receiving more information. Loma said invitations will be sent to interested stakeholders and an announcement placed in the paper for a Public Forum in May. She said the focus groups will help people weigh and balance values. In response to a question from Rosemary Furfey,Lorna clarified that there will be an additional forum after the preliminary plan is released in July. There have been suggestions about public interest in trying to get on television shows such as NW Reports, Oregon Field Guide, and Town Hall. Some of the providers may approach cable TV in their area. Lorna said Portland Commissioner Mike Lindberg is interested in developing a short, professionally produced video, similar to video projects for West Side Light Rail and others. She said it is expensive, $2,000/minute, and the discussions continue. Commissioner Lindberg may make a proposal to the Steering Committee regarding a way to reduce the cost of the video. Alan Fletcher noted this is not in the budget and it would have to be approved by the Participants. Lorna said the Washington County Forum scheduled for May will be videotaped. Project staff and Participants are working on getting space at the three county fairs. The speakers bureau hasn't been officially set up, although Lorna and Roberta have been asked to provide many presentations. They have received good feedback on the project slide show. Lorna offered project staff assistance to providers interested in giving presentations. John Thomas asked when the staff would set a date for the participating agencies/elected officials workshop. Lorna said the consultants are still refining the IRP model assumptions. Greg DiLoreto suggested scheduling the workshop for the next participants committee meeting;Lorna noted she would be out of town that day and recommended a date be set for late April or early May. f Participants Committee Meeting March 28, 1995 Page 3 Public Comments: None. Other Business: ■ Groundwater Inventory Lorna referred the group to the memo, Small Source Groundwater Inventory(see Attachment D).Water Bureau staff assisted Murray Smith& Associates by producing this inventory as part of the transmission analysis and for the IRP modeling. She asked that the Participants review the report and those with comments or those with additional wells let her know. She said they represent a fair amount of water. Tom Erwert said the Steering Committee is concerned that the status of the wells be accurate regarding current and future use. Lorna said they are following up on information on surface water sources. ■ Conservation Report Duane Robinson thanked the Regional Conservation Coalition for their letter on the latest conservation report. He said they worked very hard on it and the conservation work will be a highlight of the study. ■ Water Quality Rankings Duane also expressed concern about the City of Portland's Water Quality Advisory Committee's concern over using a national perspective to rank sources. Duane said the committee's bias is toward water quality, which leaves out perspectives on quantity and transmission. Duane said this committee is charged with having a narrow perspective and he feels their framework is not broad enough for a 50-year study. ■ Aquifer Storage and Recovery Jesse Lowman discussed a meeting with legislative leaders on a bill to authorize ASR. He said there was good response and input.DEQ didn't testify, OEC and Water Watch were both supportive. Comments included questions about water rights. Jesse felt that DEQ does not see nitrates as a serious concern.A work group will meet March 29 to discuss and refine the bill. ■ National Pollution Discharge Elimination System Permits Jesse also expressed concern about waste water and NPDES permits.He asked if there should be a work group to discuss this. He said DEQ is becoming aggressive in applying the rules and regulations to water supply facilities. Vergie Ries said Beaverton has to get permits to flush water lines and drain reservoirs. Greg DiLoreto said that Gresham needs permits to do hydrant flushing. Vergie said she was in a meeting where Oregon Health Division and DEQ were disagreeing on the interpretation of the law. Greg suggested OWUC might be the place to deal with these regulations resulting from the Clean Water Act. Tim Erwert noted this topic is not in the scope of the intergovernmental agreement for the planriing project. He felt individual governments could get together to address this issue. Tim asked Jesse to report on this item at the next Participants Committee meeting. Meeting adjourned at 2:50 p.m. Submitted by Peggy L. Murphy GAPLANIPC3-28.WPD a March 28, 1995 Since the last meeting of the Participants Committee on February 21, 1995 the Project Management Staff have been involved in the following activities: 1)Staff have met with consultants about the public involvement program and the institutional element to discuss the process from now till the issuance of the Preliminary Plan in July. A meeting of the public involvement subcommittee will be set up prior to the next steering committee. 2)Staff have met with BCI staff to discuss the conservation program report and the review process for the Conservation Coalition and the Steering Committee to review that document. 3)Staff attended a meeting at WRD in Salem on the budget issues regarding the state funded share of a Corps reauthorization study for the Willamette projects on February 23. WRD staff will present an alternative for the participants to review for presentation to the legislative subcommittee responsible for reviewing the WRD budget. The ideas discussed ways to reduce this biennium share including such things moving to a four year time span, when the actual start date would be,and if other local match shares could be generated. A fair amount of time was spent discussing the potential opposition of the agricultural community to having a reauthorization feasibility study conducted at all. 4)Staff reviewed the Columbia River National Estuary Program nomination agreement. Contact DEQ staff to suggest that the discussion of beneficial uses note that the Columbia is under study as a potential municipal supply source for the Portland metropolitan region. 5)Staff made a presentation to the Water Services Leadership Group meeting on March 6 about the outcomes for the Phase 2 process and the public involvement process. 6)Staff attended the Metro WRPAC subcommittee on Water Resources and Open Spaces meeting on March 8. The Metro work program for refining the Metro 2040 growth management decision was outlined and this group provided input on the refinement of the unbuildable lands inventory and discussed the type of recommendations that might be made about adequate standards for providing adequate water management inside the UGB. 7)Staff met with three members of the Denver Water Department to discuss with them the IRP process and desired outcomes of the RWSP for our region and how this compared with the situation in Denver. 8)Staff attended the Metro MTAC meeting on March 9 and received information on the refinement of the population forecasts that Metro is conducting at this time. The major point is that the area has grown faster than prior predictions since 1990 and this has resulted in less land supply left inside the current UGB than was anticipated. The more detailed Metro 2015 population forecasts are being developed now and will likely reflect these faster growth rates. 9)Staff has coordinated the printing and distribution of the conservation program to the Col/Willamette Conservation Coalition. 10)Staff have met with the consultants to discuss revisions to the environmental rankings based on the review of these materials as drafted. 11)Staff participated in the public involvement subcommittee meeting which occurred on March 10. 12)Staff have been working to assist in any refinements to the current water system assumptions as they will be reflected in the IRP model,particularly those related to the Portland wellfield and some of the smaller systems as they play into the transmission analysis. 13) Staff made presentations to the Geological Society of the Oregon Country and the Portland Garden Club about the RWSP utilizing the slide show, handout materials, and discussion. 14) Staff met with Metro staff to discuss the adoption process for the RWSP and the Metro role in that adoption process as well as aspects of the Metro water supply element of the Metro Regional Framework Plan. A report will be made as a part of the PC agenda for March 28. 15) Staff attended a Metro MTAC meeting on March 23 and listened to discussions about the redevelopment land survey and some bills being considered by the Legislature on standards for the urban growth boundary and on expedited hearings processes for subdivisions in urban growth boundaries. 16) Staff reviewed and provided comments to Montgomery Watson about the results of the analysis of flow impacts from a third Bull Run dam in the Bull Run and Sandy Rivers. The results of this analysis will enable a representative mitigation strategy to be incorporated into the,IRP process to reflect the costs involved with flow mitigation. 17) Staff attended the Col/Will Conservation Coalition meeting on March 21 along with consultant staff at which the conservation programs packages were discussed and reviewed. Staff is coordinating the response from the Coalition for the Steering Committee. 18) Staff have met with Montgomery Watson to discuss the refinements to the evaluation criteria, rankings, and justification language for the water quality and the environmental elements. InterOffice Memo To: Randy Volk From: Richard C. Sattler Date: September 26, 1994 Subject: Water Quality Complaints As you are well aware of I have been spending a majority of my time answering questions about the quality of the water. I would venture to guess that the duration has been over the last month and a half. The amount of calls have ranged form 50-75 calls per day regarding this issue. Of these 50-75 calls per day, 1-12 require my attention. I have listed a few of the descriptive terms used: sewer water; is this Tualatin River water we are drinking; aquarium water, water with earthy smell; horrible water; etc.. Reasons for the increase of calls regarding water quality: 1). increase of water temperature of the Clackamas River 2). increase of growth on the river(algae) 3). rains of the labor day weekend stirred up the water in the river We are not alone,the City of Lake Oswego has also noticed an increase of customers complaining about water quality. Due to the increase of calls,Lake Oswego has added carbon to their treatment of the water. Carbon is known for absorbingtremoving the taste and odor of the water. I have been told that this process is time consuming, messy and costly. I would also like to note that this a yearly event,with this year being particularly bad. When I receive a call concerning the water quality I volunteer to take a bacteriological sample from their location(usually inside the house from a kitchen or bathroom_faucet). My theory is that by having a piece of paper, (the bacteriological report from the laboratory)I am able to give the customer documentation of the water quality. The results are usually given via telephone, unless the customer requests a copy of the bacteriological report.
