Visitors Comments No visitors were present. 5. Water Supply Update and Other Information — Dennis Koellermeier Mr. Koellermeier referred to the handout, an excerpt from an Oregonian newspaper article, which he found interesting in that a water district on the other side of the Portland metropolitan area is facing somewhat the same issue as this Board—will they exist and what will their boundaries look like. This article was provided for background information to let this Board know it is not alone. Current Water Supply Issues -Mr. Koellermeier reported that our supply continues to be adequate. Depending on the day, we have 10-20 percent reserve capacity this time.of year. Tigard Water District 1 August 28, 2006 Water Sunnliers Information—This month Portland began the process of blending(10 percent ground water with 90 percent Bull Run water) instead of using all of the stored water and then going 100 percent on ground water. Because some of the users complained about a different taste and some of the commercial users had to deal with chemistry changes in the water, they adopted the policy three years ago of starting sooner using ground water and doing a blend. In response to questions posed by Commissioner Froude, Mr. Koellermeier commented that he thought in the past he had shared with the Board a model predicting three possible scenarios of how long the Bull Run stored ground water would last as compared to the weather. Mr. Koellermeier receives a monthly update showing where City of Tigard is on the curve (reflecting high,medium and low use) and he will include a copy in the next board packet. The Joint Water Commission(JWC) and Lake Oswego continue to provide water to the City of Tigard. Lake Oswego struggles a little bit on these really hot days and the city expects that to happen and it can work around that. Most of their issues are a result of old equipment and facilities,which have been identified and addressed in the study we are doing with them, and need to be updated to be more reliable during hot weather. The ASR continues to provide water for Tigard. We have probably used about 75 percent of the water now. By the end of September, Tigard will have used all the stored water and then the recharge period starts. The City of Tigard injects for eight months,rests for a month and then uses for three months. Tigard's study with Lake Oswego continues to proceed. There will be an upcoming meeting (date is still being worked out between the Lake Oswego and City of Tigard councils). The IWB has been invited to attend this meeting that will be held some time mid-November. When that date is determined, Mr. Koellermeier will share that information with this board. It is an open meeting and the Tigard Water District board is welcome to attend. The meeting will be held in Lake Oswego. Things continue to look positive. The City of Tigard is really on the front end of a multi-chapter study and Mr. Koellermeier has seen two of the nine chapters. The study is due in January. The JWC plans to publish the draft environmental impact statement in November. There will be about a four-month study and comment period. The JWC and the Lake Oswego material will be available at approximately the same time and Tigard will be able to compare that to the Portland contract(three points on the decision process so decision makers can look at all those options at relatively the same time). Commissioner Charles Radley asked Mr. Koellermeier what is the current percentage of fluoridation. Mr.Koellermeier responded that the City of Tigard obtains about 1.5 mgd from the JWC starting the middle of June through the first or middle of September,depending on flow needs. By the time you blend 1.5 to 10 mgd,it brings the percentage down to approximately.006. The issue is,it is not a perfect blend. We don't blend it before it comes into the city and it doesn't get distributed evenly. There are pockets that have the complete fluoridation load and it tapers down from there. As the City of Tigard does other monthly testing,we also test for fluoride. Those results are plotted across the city. It is an after-the- Tigard Water District 2 August 28, 2006 • fact concentration issue but,by modeling,the City of Tigard can over time start to tell people that generally in August in your neighborhood you can expect this much fluoride in the water. Commissioner Delphine asked,what is the source of this fluoride? In response, Mr. Koellermeier stated the City of Beaverton injects fluoride in all of their water. Commissioner Delphine then asked,where do they get that fluoride from? Mr.Koellermeier indicated he did not know who their supplier was,but that he could acquire that information. Most of the questions about fluoride are concerns from parents who are administering fluoride to their children and they want to make sure they don't overdose. 6. IWB Update—George Rhine/Janet Zeider Commissioner Rhine reported there was an appeal for a refund on a residential leak. It was resolved to split the remaining cost with the homeowner. The homeowner promptly fixed the problem; it was expensive. As a non-agenda item,Commissioner Rhine made comment to the IWB board that the board ought to be proactive in deciding how it will handle the inclusion of the City of Bull Mountain,if and when the vote is passed,rather than wait to the very end. Whether that is a charter issue or whether they want to try and assign that to the TWB board to handle or what, but somehow if the City of Bull Mountain is formed,then that entity needs to be a party to the IWB. Commissioner Rhine indicated his comments were acknowledged. Because it was a non-agenda item,there was no resolution. 7. Non-Agenda Items When there is a light agenda,Mr. Koellermeier indicated he would like some direction from the board as to whether they want to continue to meet or give him the authority to talk to the Chair(or Vice Chair)to determine if a scheduled meeting could be cancelled. The board members discussed their options regarding meeting practices making reference to by-laws, state laws and Mr. Balfour's comments. As a suggestion,Mr. Koellermeier said we can schedule monthly meetings. A week before the meeting,Mr.Koellermeier will discuss the agenda with the Chair(or Vice Chair). If it is determined to be a light agenda, a decision may be made to cancel the scheduled meeting. A meeting cancellation notice would be posted on the web site and public buildings. 8. Set next meeting date—September 25,2006,at 7:00 p.m. 9. Adjournment Commissioner Delphine motioned to adjourn,Commissioner Rhine seconded the motion, and the board voted unanimously to adjourn the meeting at 7:30 p.m. Joy Ko77KTD Recording Secretary Date: /0 — — c2 X9 ' Tigard Water District 3 August 28, 2006
