Intergovernmental Water Board Meeting Minutes July 15, 2003 Members Present: Brian Moore, Norm Penner, Bill Scheiderich and Dick Winn Staff Present: Ed Wegner, Sally Mills, and Twila Willson Visitors: Roel Lundquist 1. Call to Order, Roll Call and Introductions Commissioner Bill Scheiderich called the meeting to order at 5:41 p.m. Twila Willson called roll and announced that Patrick Carroll had asked to be excused. 2. Approval of Minutes—April 15, 2003 and June 11, 2003 Commissioner Brian Moore motioned to accept both sets of minutes and Commissioner Norm Penner seconded the motion. The vote was unanimous to accept the minutes of the April 15, 2003, and June 11, 2003, meetings. 3. IWB Meeting Schedule Review Ed Wegner stated that official notification had been received from King City's City Manager that Commissioner Dick Winn would now be representing that agency and Gerry McReynolds would act as his alternate. Jan Drangsholt had resigned from the City Council. The proposed meeting schedule for the next six months was distributed. Mr. Wegner suggested that perhaps the IWB would want to meet only at the combined workshop with the Tigard City Council on the quarterly Tuesday meetings and hold other business matters until the regularly scheduled Wednesday meetings. The Board discussed the matter and decided not to meet for a board meeting before the joint IWB/City Council meetings unless there was a pressing matter that could not wait until the next regular meeting. 4. PW Director's Report—Ed Wegner Mr. Wegner presented the operations report as Dennis Koellermeier was on vacation. ASR Wells—Tigard started withdrawing water from the ASR well on July 8 at approximately 1.2 mdg and .6 mgd is coming from groundwater wells. The average water usage since April has been 4 mgd from the Joint Water Commission (JWC) and 6.3 mgd from the City of Portland. The summer demand period for water is underway and we have been in the normal usage group as outlined in the summer plan with only two days of peaking that went just over 12 mgd. Mr. Wegner distributed a graphic report of the Year to Date Annual Totals showing where and how much water Tigard purchases. Historically the water purchases from the City of Portland have been at 62% of our consumption but we have dropped down to 59%. This may result in paying a minimum purchase penalty fee to Portland, but the drop was done consciously in order to take more water from the JWC at their lower rate. We will still see a savings even by paying the penalty fee. My 15,2003 Intergovernmental Water Board 1 DRAFT COPY The Customer Confidence Report (CCR)was recently distributed through direct mail. The report indicated that there were no violations reported. Over the last three years Sally Mills has produced this report at a significant savings to the City while still providing a high quality, informative brochure to the citizens. Performance goals were set last year of a preventative maintenance nature to replace 40 fire hydrants and 40 2" service lines. Historically only broken hydrants and service lines in need of repair were replaced. These goals were achieved and will help with water loss. The conservation program is working well. The landscape rebate program has expended all the money that was budget for last fiscal year'02-'03 as well as the money budgeted for the new fiscal year'03-'04. Sixty letters have already been sent to citizens who applied for the rebate too late. A new washing machine rebate program started July 1, 2003, which offers a $50 rebate for energy and water efficient washers purchased after that date. These programs are set up by a regional water consortium however each entity administers their own program. The Vulnerability Study contract will be presented to the Tigard City Council next week for their approval to start the construction of a second ASR well on Bull Mountain Road. 5. Informational Items—Ed Wegner Informational packet articles were briefly described. 6. Public Comments—None 7. Non Agenda Items -None Commissioner Scheiderich asked for an update on the progress in collecting the water quality information for publication about the Wilsonville Treatment Plant. Mr.Wegner stated a comparison or various agencies in the area was being assembled and would be ready by the end of the month. Commissioner Scheiderich requested that the final information be sent to him so that it could be published in Beaverton's newsletter also. Commissioner Winn asked how Tigard's water quality compared and Mr.Wegner said the Water quality in Tigard is very good and only occasionally has chlorine needed to be added and no mixing problems. No comments have been received from citizens regarding the fluoride issue. The City Manager received one call from a dentist, who was in favor if fluoridation and volunteered to help educate citizens and offer assistance if it became an issue. 8. Next meeting date— Wednesday,August 13, 2003, at 5:30 pm in the Water Auditorium The Indonesian delegation may be in town that day and their water director may visit us at that meeting. 9. Adjournment At 6:03 p.m., the general consensus of the board was to adjourn the meeting and reconvene in the joint session with the Tigard City Council at 6:30 p.m. Intergovernmental Water Board 2 July 15,2003 DRAFT COPY Public Works Memo TO: IWB "Public Works Makes it Hawn' FROM: Richard C. Sattler 0601 RE: Establishing Wholesale Water Rate on "Credit for Water Leaks" for fiscal year 03/04 DATE: July 11, 2003 The section of the Tigard Municipal Code, "Credit for Water Leak", 12.10.070 needs your direction for setting the wholesale water rates. The issue regarding this section is that the Intergovernmental Water Board is required to set the average wholesale cost of water for each fiscal year. Background: Each year we receive notice from our various water sources (JWC, City of Portland, TVWD) regarding Tigard's cost of water per 100 cubic feet (ccf). This year the wholesale rate from the City of Portland is $1.091 per ccf. Based on past practices of determining the wholesale cost, staff is recommending that IWB establish a rate of $1.091 per ccf for fiscal year 2003/2004. Please find attached Tigard Municipal Code 12.10.070 and the "Request for Adjustment due to a Leak". 1AP U tflity Di%A W B 0304 rate.doc REQUEST FOR ADJUSTMENT DUE TO A LEAK The City of Tigard Utility Department has a policy of issuing partial credits for leaks that are repaired in a timely manner. The city expects leaks to be repaired within ten days of discovery. Credits are based on your average usage for the same period in previous years. This average is deducted from the total consumption used during the time of the leak. The excess usage is charged at the current wholesale nate of water,with the difference between wholesale and resale cost deducted from the utility account as the Credit for Leak.

CITY OF.TIGARD,. OREGON' DATE:. August 12,.2003 TO: Dennis Koellermeier,Assistant Public Works. Director FROM:. Brian Rager,.'En.gineering. Manager RE: Rece Bly E-mail,. Dated.8/4/03 Below are responses to each of the nine requirements in Mr. Bly's e-mail. 1.. Adequate.funding:. • Based on preliminary estimates for the reservoir-project, we anticipate the cost of the project to be approximately 4.2 million dollars. In the FY 2003/2004 budget, we have budgeted 1.8 million dollars from the Water CIP Fund, and another 1.9 million dollars from the Water SDC Fund, for a total of 3.7 million dollars available. The balance of the project costs will be budgeted in the FY 2004/2005 budget. Therefore, we have adequate funds to complete this.project. • The City also has the option of selling limited obligation revenue bonds to help with the project financing. A bond sale of this type,, which is approvable by Council, is anticipated in the FY 2003/2004 budget. 2.. Qualifications and experience of City team: • Brian Rager's experience: i. Worked 1.5 years for a Portland contractor as a Project Coordinator. Familiar with budgeting, scheduling, quantity take-offs and subcontractor procurement and coordination. ii. 12+ years for two local municipalities in development review. Very familiar with the land use process, construction process, neighborhood issues, etc. iii. Current position.in PW will allow him to focus much of his time on the project at hand. This is not a situation where the City is taking a staff person and adding project management to their existing full-time position. • MSA Experience: We can provide a copy of their team information from their Proposal. 3. Schedules: • Just as the District can be damaged from delays on the City's part, the City can be financially damaged due to delays on the District's part. The issue at hand is getting the two projects into the CUP process. Our latest schedule, which was updated from when we sent the first list of requirements to Dom, shows that CUP application could begin in mid-September, 2003, with a reservoir completion date of around May 30, 2005. If they want us out of the way by May.1, 2005, then CUP application should be taking place by mid-August, 2003. Obviously, since the. District and City have not conducted a neighborhood meeting yet, a,mid-August application will not be achieved. So, if we experience delays from the District, but they still want us to meet their deadline, our costs for the project will go up. Does it seem fair that they would still be entitled to the $200,000 that has been informally agreed to? It seems that the $200,000 should be contingent on their cooperation and avoidance of delays that impact our schedule. Any increase in our projects . costs due to their delays should result in an equal decrease in their compensation amount. • -We are certainly willing to share our schedules with them, as we have to date. 4.. Right of. District to. review. City designs.and contracting: • I see no problem with this so long as they do not delay our schedule. The District will not.have the power to approve or deny our plans. They, as well as any other member of the pubic, have a right to review our plans. We can state very clearly that our reservoir will be constructed to meet or exceed industry.standards, as well as other applicable local or state construction codes. • Minimal engineering peer review is.at their cost and again, cannot be allowed to lengthen our schedule. 5. Bond or escrow account to'cover City.project: • The City should•not incur the cost of a bond to guarantee our work. If we.answer Question #1 above, and agree in the IGA to complete the project, that should be adequate. 6.. Concise plan.for ongoing. monitoring and maintenance of City structures,.' utilities: • The City will have continuous 24/7 telemetry monitoring at the facility, to include measurements of ph, turbidity, chlorine residual, conductivity, pressure. The system also addresses reservoir levels, security and automated valve position and control. • The City will perform weekly visual inspections of the facility, with emphasis on security,vandalism, etc. 7.. Fair and reasonable.compensation: • I think we need to stick to the concept of a voucher system, where we place $200,000 into an account for use only on the Ryder site. These funds are available until either expired, or when the project is finished. Any amount remaining will be .returned to City accounts. • Again, if delays on their part negatively impact our schedule and increase our project costs, it seems that the voucher amount should decrease by that same amount. 8. No transfer or assignment of easement.without District approval: • This topic has been discussed before. We agreed. PAGE 2 t t 9.. District wilt not indemnify the. City for.use.of. District site:. • The original draft of the IGA, as prepared by the District, included an indemnity clause purely in the District's favor, should any action by the City's part in operation of the reservoir cause damage to the District's parcel. •. Our attorney suggested an equalizing indemnity statement whereby the District would hold the City harmless for any damages caused by the District's use of the easement area. We are not asking them to indemnify us for their use of the school site, as suggested by Mr. Bly's comment. We only want indemnity for the easement area. Why? Because the District plans to use the easement area for part of their play area. • Conclusion: A mutual indemnity clause should be included in the agreement.

A demonstration of adequate funding for the City's project. 2. A list of qualifications and experience of the City's management and consultants demonstrating their ability to perform and manage the work. 3. Schedules, Since the District can be damaged by significant slippage in the City's schedule,the District should have the right of review and approval. 4. The District should have the right to review and approve the City's designs and contracting processes. It may also be prudent for the District to utilize some type of minimal engineering peer review to monitor the City's project designs and progress. S. A bond,escrow account or other method of surety that will provide the District a means to complete the Citys project(or re-construct the District's site)in the event the City defaults or has funding woes. 6. A concise plan for ongoing monitoring and maintenance of the City's structures and utilities. 7. Fair and reasonable compensation. The District.suggested$200Kr which the City has said was fair. 8. No transfer or assignment to water districts or other entities without prior approval by the District 9, The District has declined to indemnifythe City for the use of the District's own property to operate a public school.

Feasibility Study Project Review • The coordination with Raw Water Pipeline and other water resource management projects has been the main area of work. A meeting was conducted to review the Regional Water Supply demand model. The coordination of the demands between these two studies will be important for forecasting future needs.Additional demand forecast information may need to be developed to refine the analysis. • The Congressional authorization and appropriations process is still making progress. The Senate bill 625 has passed the Senate for the Study authorization. Congressman David Wu is working to secure passage of HB 1525 on the House Suspension calendar. He has contacted House leadership and the Democrats on the Resources_Committee.During the last month we received letters of support from various business and stakeholder groups. • I attended and presented a paper on the Water Supply Feasibility Study at the American Water Works Association Annual Conference in Anaheim,California. The conference was educational and informative with a wide range of technical sessions. For my presentation session was lightly attended,because it was scheduled on the last day of the conference. • The next phase Request for Proposal(RFP)for the Draft Environmental Impact Statement (ELS),permitting and FEIS has started. The second amendment of Joint funding agreement will be forwarded to the partners for next phase. The amendment will include the next two fiscal years. • The Reclamation has completed an Environmental Assessment on the Hagg Lake Resources Management Plan. The Ad Hoc workgroup meeting was held to review the EA and alternatives. The key concerns are maintaining water quality and impacts of increased recreational development. Submitted by Tom VanderPlaat,WSFS Project Manager—June 26,2003 Progress Report 1 7/16/2003 Westside Water Supply—A Comparison in Water Quality Earlier this summer Tigard water customers received a copy of Tigard's annual water quality report for drinking water. This report explained the Environmental Protection Agency's (EPA) standards for drinking water. All water systems are required to meet these standards when providing drinking water. Of the over 250 contaminants water systems are required to test for, very few, if any, were present in Tigard's water system. Of those contaminants detected, all were at levels below the maximum contaminant level (MCL) set by the EPA. Last year, Tigard supplied over 2.4 billion gallons of water to our consumers. Since Tigard does not have ownership in a water supply capable of meeting our consumers' growing demands, Tigard purchases over 90% of its water supply from the City of Portland and Joint Water Commission. Tigard supplements the remaining water demand through the use of city-owned groundwater wells. Considering the amount of water Tigard purchases from other agencies, the following table was created in order to display the "quality" of water received by Tigard from our suppliers. (Please note that the analysis results provided are the "highest" amount of contaminant detected.) In addition, a number of citizens have continued to express their concerns regarding Wilsonville's use of the Willamette River as a drinking water source. Wilsonville's data has been included to provide citizens with a way to compare Tigard's drinking water quality to the quality of Wilsonville's water. (Please note, only detected contaminants are included. For all three sources, the vast majority of contaminants were not detected. Examples of non-detected contaminants include Arsenic, Fluoride, Mercury, PCBs and Dioxins.)

We will blend the groundwater with Bull Run water at a rate of about 45% groundwater to 55%Bull Run water. Page two of this fax outlines the expected water quality. It takes approximately 24 hours for the blended water to move through the distribution system, so the earliest you may notice a change in water quality will be on Wednesday. We anticipate running groundwater for at least a month. Weather conditions and water demand will dictate when we return to a 100%supply of Bull Run water. We will notify you via fax before we turn off groundwater. If you have any questions,please do not hesitate to call me at 503-823-7481. If we should direct this fax to someone else, let me know and I will correct our records.

Feasibility Study Project Review. • The Study focus has been on completing the Study tasks and finalizing the technical memos for the various sections. The contract amendment for the economics analysis has been developed and about ready to be signed. This task was delayed until the dam engineering work by Reclamation was finished. The hydrology model has been refined to reflect current operations. MWH will be reviewing the model results with the Water Managers over the next few months. I have continued to coordinate with City of Hillsboro staff on the JWC Raw Water Pipeline Project. The climate change Study contract has been signed and work started on this part of the Study. • As previously discussed at the Water Managers Group,Jeanna Cernazanu and I have been working to establish the WSFS Policy Steering Committee(PSC). The PSC had an orientation session on June 23 to discuss their roles and responsibilities. One of the purposes of the PSC is to provide easier access to policy makers for stakeholders such as the Hagg Lake Neighbors and interested citizens. Tom Brian,Clean Water Services Chairman was elected chair of the Committee. Additional information was reviewed with them regarding the Feasibility Study. PSC members expressed an interest in touring Hagg Lake and other areas related to the Study. A tour is scheduled for July 22 from 2-5 pm. The PSC meetings,will be open to the public and provide an opportunity for public input at the meetings. The anticipated term for the PSC is two years as they work through the Final Environmental Impact Statement process. It is important that this committee's work be well supported by Partners staff, so can,efficiently and effectively complete its work. • In the area of federal funding process,we have continued to pursue letters of support and succeeded in receiving one from Intel. Mark Jockers and I met with Congressman Wu's new field representative,Avalyn Taylor. She previously worked for the Portland Audubon Society and is interested in assisting the Partners on this project. Kelly Scannell,the previous field representative has been promoted to the Wu's Washington DC office. The authorization process should be completed in the near future. Congressman David Wu continues his efforts with House leadership and the Democrats on the Resources Committee. Tim Ruffen our Washington DC governmental affairs contact has recently changed firms. He moved from Reed Smith to Peyser and Associates. Tim will be retained to maintain continuity with the work on the authorization and appropriations. A new contract will developed to for this work. • The next phase Request of Proposal(RFP) for the Draft Environmental Impact Statement (EIS),permitting and Final EIS is being reviewed and should be advertised next week. I have met with several firms interested in this phase of the Project. Proposals will be due in middle to late August and I will be asking for members to serve on a consultant selection committee. The second amendment of Joint funding agreement will be forwarded to the partners for next Progress Report 1 7/16/2003 Tualatin Basin Water Supply Feasibility Study phase. The amendment will include the next two fiscal years and does not include any federal funding currently being requested.

Based on on-going supply analysis,the City of Portland Bureau of Water Works will supplement the primary Bull Run water supply with water from the Columbia South Shore wellfield. "To ensure sufficient supply of high-quality water throughout the summer and fall,we will start operating the wells on Tuesday,July 22,"said Mort Anoushiravani,Water Bureau Administrator.'There is no shortage,but we anticipate warm weather and want to stretch our supplies into the fall,as needed- f=ortunately,we have a high quality secondary source in the Columbia South Shore wellfield. As a result, all water served will meet or surpass state and federal drinking water standards." The City's wellfield holds 25 production wells with a combined capacity of 100 million gallons per day. Initial groundwater production will be about 65 million gallons a day, approximately 40%of daily demand. ! The City will produce groundwater to blend with Bull Run water as long as needed to meet seasonal demand. "We will increase, decrease or discontinue the blend in order to maximise reliance on Bull Run while ensuring adequate regional water supply,"said Anoushiravani."We will continue to track the weather,forecasts,stream flows and water demands throughout the summer." Most City of Portland customers will receive the 60/40 blend. Customers east of Powell Butte will continue to get 100% Bull Run. None will receive 100°/0 groundwater. There is little difference in taste between blended and 100%Bull Run water. The blended water temperature may be slightly cooler. Current Bull Run temperature is about 60 degrees F. and groundwater is about 55 degrees F. Production this season will include about 350 million gallons of Bull Run water, injected into the welifield last winter.The Water Bureau is testing this process of Aquifer Storage and Recovery(ASR)to see if it can provide a long-term reliable means of storing abundant Bull Run water during winter months in order to meet peak summer demands. An Equal Opportunity Employer OregonLive.com's Printer-Friendly Page rage i of z Oregon Live.corn Everything Oregon Sign of a dry summer: Earliest tapping of wells in Portland in 18 years 07/22/03 SCOTT LEARN Portland will begin tapping its Columbia River well fields today to supplement water from the Bull Run reservoirs,the earliest the city has switched on the wells as a summer backup in 18 years. City officials say the potential for a hot and dry summer make it prudent to pump the wells now.A hot June, water releases for endangered fish,and increased water use in the growing suburbs are contributing factors. Portland Water Bureau surveys indicate customers prefer water from the city's primary water source,the two Bull Run reservoirs in a forested reserve close to Mount Hood.The wells on the Columbia River's south shore have been threatened off and on with industrial solvent contamination,though the bureau says all 25 production wells are free of contaminants and meet federal water-quality standards. The bureau supplies 830,000 customers in the city and suburbs,including Gresham,Tigard and Tualatin. Customers east of Powell Butte,including those in Gresham,will continue to get all Bull Run water because of the way the distribution pipes run. The bureau plans on an initial blend that includes 40 percent well water,pumping at a rate higher than in past summers.Water Bureau spokeswoman Ross Walker said the bureau would have to use a higher percentage of well water if the weather stayed dry and the agency waited until later in the summer to pump. "It's better for us to start using the wells earlier rather than later because we maintain a more constant blend," she said. The bureau's notice of well water use did not include a call for extra conservation.The Oregon Natural Resources Council environmental group and citizen watchdogs have argued that the bureau should tum to conservation before flipping on the wells.They say the bureau hesitates to do so because it would cut water sales and revenue,though heavy pumping could draw industrial groundwater contaminants into the wells. Bureau planning documents say conservation messages work but can lead to decreased revenues for the bureau,extra advertising costs and"significant economic hardship on the community." Walker said the bureau will stick with a conservation plan that calls for"wise water use,"such as careful Watering of lawns."We'll be running our radio blitz starting next week,asking for wise water use,"she said. "But we aren't anticipating a shortage at all." If the summer and early fall are dry and hot,this season could see the longest draw in the wells'history, continuing until fall rains begin.The Portland region's most severe water shortage came in 1992,when regulators'concerns about well contamination prevented use of the wells. Regna Merritt,executive director of the Oregon Natural Resources Council,said she thinks the bureau wants to test its experiment of pumping Bull Run water into the well fields during the winter for summer use. Last winter,the bureau sent about 350 million gallons of Bull Run water into the wells,about a six-day supply of well water at planned summer pumping rates. "I doubt they're interested in promoting conservation right now,"Merritt said."I think they're very interested in pumping that well field heavily so they can determine what happens with their first aquifer-recharge experiment." Walker said the bureau needs to tap the wells,and its decisions are based on"normal water supply http://wvvw.oregonlive.com/printer/printer.ssf?/base/news/105887564285620.xm1?oregonian?lcg 7/22/0: UregonLrve.com's rnnter-Fnendly rage rage of management." Bureau officials say the water quality is top-notch,that the city has invested more than$50 million in well development and that the wells can be protected from nearby industrial pollution. The Bull Run reservoirs hold about 10 billion gallons.If the weather stays dry and hot into November,bureau projections indicate up to a 7 billion gallon shortfall between demand and what the reservoirs alone can supply. Even with normal conditions for the rest of the summer,the shortfall would be 1.4 billion gallons,the bureau estimates, indicating that summer well use is likely to become more routine. Releases for endangered fish are helping deplete supplies.The bureau plans to release about 3 billion gallons this summer to help endangered fish in the Bull Run River downstream of the reservoir dams. A hot June also spiked demand.Four June days set high temperature records. Growth increased suburban water use by 6 percent from 1997 through 2002,bureau records show.Overall water use remained flat thanks to decreased use in Portland. The city has tapped the wells,north of Interstate 84 between Interstate 205 and Blue Lake, 13 times since 1985 as a backup to the Bull Run,including seven times as a summer supplement. The bureau last tapped the wells in the summers of 2000 and 2001.

Except for Tigard,which brings in 90 percent of its water from outside the city,water agencies say they have enough around to fill everybody's needs.To economize,Tigard residents were asked last week to water their yards every other day. Although water supplies are adequate in most locales,Tuesday's brief drenching by a passing thunderstorm and the day's milder temperatures caused at least one city official to express thanks. "The rain made a difference,"said Don Otterman, North Plains'city manager."We're definitely happy to see it cooler." The coolness, he explained, allowed the city's well pump to move ahead of water demands from the 1,660 residents and the businesses in town. Because of pumping limitations,the city can replenish its million-gallon water tank at about 350 gallons a minute,somewhat below the rate that goes out when weather's hot. "Water is available,"Otterman said,although the city newsletter has urged water conservation. Otterman's municipal neighbor six miles west,Mayor Robert Orlowski of Banks,said that barring a prolonged heat wave,the city's watershed north of town and a backup well should handle needs until fall rains arrive. "We take measurements every day,"Orlowski said."It's not going to take us by surprise"if the supply drops off or demand increases."We see the trends.There's not a trend right now." If a trend appeared, he said,the city would ask its water customers to sprinkle their lawns every other day. It would also curtail supplies to bulk customers who sometimes purchase up to 40,000 gallons at a time for agricultural and other purposes. Farther south in Forest Grove, Rob Foster,the city's public works director,said last spring's routine filling of Hagg Lake behind Scoggins Dam assured his city and other agencies of enough water until fall rains normally begin. Along with Beaverton, Hillsboro and the Tualatin Valley Water District, Forest Grove is a member of the Joint Water Commission,which provides varying proportions of the four agencies'total needs from the lake.The four also draw water from the Barney Reservoir farther west,which also filled to capacity in the spring. On Tuesday,a representative from the joint commission,Tahanni AI-Essa,assured the Tualatin Valley district's governing board that"we will have enough overall to get through this year's water season." The board heard the same message from Portland,the water district's other principal supplier. Mark Knudson,the Portland Water Bureau's operations and maintenance director,said the city's Bull Run Reserve in the Cascades and wells near the Columbia River were combining to assure enough water for his city and its several suburban agency customers. http://www_oregonlive.com/printer/printer.ssf'?/base/metro west news/10602575567430.x... 8/12/2003 OregonLive.com's Printer-Friendly Page Page 2 of 2 But he also urged conservation by the customers'customers."W.hile there's enough,"he said,"we don't have water to waste."

It continues the myth about. .an apparent extra vulnerability.of the vigard area to water shortages. This has been reported erroneously, annually, for over thirty (30) years. You state "only Tigard, which has-little water to call its own, has asked- customers to cut back on lawn watering." Further, "except for Tigard, which brings in 90 percent of its water -from outside the city, water agencies say they have enough around to fill everybody's needs." The fact is Tigard is no more nor less vulnerable to water shortages than" any other water purveyor which must import or purchase water from others. To. name a few: Tualatin Valley'Water District, City ,of-Tualatin, City of Gresham, West Linn, all east Multnomah County water districts,,-and many, many more. None of these entities has the capability to produce sufficient potable water and must, essentially, import 100% of fiheir supply. Those entities which produce, own, and sell surplus water are few indeed, including Portland (Bull Run) , Hillsboro, Forest Grove, Beaverton (Upper Tualatin River) , Clackamas Water District, City of Lake Oswego (Clackamas River) , and Wilsonville (Willamette River) . All others must import water and are dependent upon one or more of. the agencies listed above. . Tigard imports almost all of its water from Portland's- Bull Run system but it is not any more .vulnerable to water shortages than others dependent upon importing water. It is important to note that Portland does not discriminate amongst its many wholesale water customers and treats everyone equally. In times of water shortages.of Bull Run water, Portland requests (sometimes demands) that all its customers conserve water: - This year, as it does every summer to be prudent, Tigard has suggested that citizens conserve' water by alternate day . lawn sprinkling, not that they are required to do so. All entities should encourage water conservation_. I hope this clarifies 'a long ongoing misrepresentation of the facts. Siricerel , --- 4 -Copy.. to:. Bill Monahan <RotE.

"Any new regulation affects water utilities,"noted Mort Anoushiravani, Water Bureau Administrator,"because it We standards by which we-accomplish our work.And sometimes,as with the LT2ESWTR,compliance may require substantial changes.-The two most relevant local issues in this regulation are treatment and uncovered finished water storage." "Currently Portland's drinking water is unfiltered,and disinfected with chloramines," said Anoushiravani.'The new rule will requiremore stringent treatment to inactivate Cryptospoddium,a microorganism found in surface waters throughout the world.Our monitoring shows only very low levels,but the rule requires higher guarantees of inactivation than we can provide. Simply put,we'll need to change our treatment. "The regulation also requires changes to our uncovered reservoirs, which is currently underway at Mt. Tabor and Washington Parks." "As with most federal regulations,there is a 90 day period for public comment,"said Anoushiravani.'The EPA's last date for public comment is November 10,2003."
