Visitors present: None
I. Call to Order
Chairman. Robert Mitchell called the regular meeting of the Willamette Water Supply
Agency to order at 7:05 P.M. at the City of Tualatin Police Department Building.
Il. Review of Minutes from March 1'5, 2001
The minutes from the March 15, 2001 were distributed. A motion was made Keith Mays
to approve the minutes from the.March 15, 2001 meeting as presented:and seconded
by Paul Rogers. The motion was voted on and unanimously carried.
lll. W VSA Financial'Update
Todd Heidgerken distributed to the Board a financial update that compared the 2000-
2001 budget to current expenditures for July 1, 2000 through May 29, 2001. WWSA
has spent$84,672. This leaves $78,328 remaining Of the budget. Heidgerken
indicated that most of the categories are well below the budgeted amount except for the
Services category. It is expected that the Water Quality Testing amount will be fully
used and that the Services amount will,be exceeded however it will be within the •
amount included in the contingency category. Overall, WWSA is expected to be under
• budget.• •
IV. Consideration of Contraction out the Administration of WWSA
•
Robert Wescott, Paul Rogers.and Jim Doane (the nominating committee) provided the
Board with an overview of the issues discussed and the process,used,in interviewing
the various,candidates. The nominating committee discussed the value of hiring a firm
as opposed to an individual to administer the candidate. The nominating committee

,a��i ss �` .,..,, �'.a '.'. < `� �r� ! :,y..r�;� �.J,",.'� ' '4;77"
narrowed the selection to two firms, Burton Weast with Western Advocates and Greg
Leo with the Leo Company. A policy discussion regarding the level of activity of WWSA •
in the future was held and it was agreed that a firm would best provide the typeof
assistance needed by WWSA. In order to make a decision, the nominating discussed
their desire to ask the two candidates to provide a request for proposal and make a
determination based on all of the information collected.
Joyce Patton explained the uncertainty surrounding the type of things that the City of
Tigard could participate. Tigard would be concerned with participating with WWSA if it
took a very proactive stance. Tigard is comfortable in participating in activities that help
preserve the water right and evaluate water quality.
Robert Wescott described an approach that would allow for'WWSA to work at a "base"
level however individual members could request (and pay) a firm if they want a more
involved program. The Board discussed the value of participating in activities
associated with protecting the water right and agreed that these type of activities would
be justified.
Mike McKillip explained that the City of Tualatin has similar concerns to Tigard. The
need to protect the water rights is important in order to keep options available in the
future. We:will have a better understanding of the acceptance of the Willamette after
the plant has been operating for a while.
Ed Wegner suggested that WWSA would focus on protecting water rights and •
evaluating water quality yet there will be an opportunity for those entities that want to
participate in additional projects. Wegner noted that this process was used for the
development of the:Preliminary Engineering Report. It was noted that a firm would
provide this type of flexibility.
Keith Mays moved that the interview committee be authorized to negotiate and enter
into an agreement with a firm to provide administrative services to WWSA. The
proposal'will be distributed to the WWSA Board Members and an opportunity is
provided for any of the Board members to comment prior to a document being executed
by thechair. The agreement must be within the scope of the WWSA 2001-2002
budget. Joyce Patton seconded the motion: The motion was approved unanimously.
V. Nomination of WWSA Board d Chair'and Vice Chair .
The Board discussed the need to select a Vice Chair to fill out the remaining term of
Paul Hunt.
Bob Westcott nominated Paul Rogers to serve as Vice Chair for the remainder of the
term• acated by PaulHunt: Keith Mays seconded the nomination.' The,Board approved
the,nomination urianimousl T -

Given that current Chair, Robert Mitchell, will not be returning as a Commissioner,the
Board discussed the.desire to nominate a Chair and Vice Chair for the 2001-2002 term.
Any nominations would then be subject to election during the July meeting.
Bob Westcott nominated Paul Rogers to serve as WWSA Chair for 2001-2002. Keith
Mays seconded the nomination. The Board approved the nomination unanimously.
Joyce,Patton nominated Robert Westcott to serve as WWSA Vice Chair for 2001-2002.
Paul Rogers seconded the nomination. The Board approved the nomination
unanimously.
VI. Executive Director Report
A. WTP Update: Todd distributed the most recent Willamette Water Treatment Plant
construction monthly report. It was noted that the July meeting would be
coordinated with a tour of the plant. Greg DiLoreto reported that Wilsonville is
currently reviewing a draft phase Il-agreement between TVWD and Wilsonville.
B. Water Right Permit Extension Application: The Willamette River water right permit
extension application was submitted last week (week of 5/21/01). A;copy of the
submitted application will be mailed to the WWSA managers. Application asks for
an extension until 2076. The cost of developing the water right to-date is
approximately$8.9 million. This amount does not reflect the funds expended by the
1±� City of Wilsonville.
C. Water Quality Monitoring: Current program is on schedule. The City of Wilsonville
has offered to pay for the entire water quality-monitoring program for the next fiscal
year.
D. Interviews for WWSA Administration: Todd thanked the interview committee for their
substantial involvement and flexibility in the process.
•
E. Willamette Basin Reservoirs: The Army Corps of Engineers has recently held.
workshops on the operation for this summer. Noted that this is currently the second
driest year on record. The low water conditions will have an impact on how the
reservoirs are operated this year.
F. TVWD Ordinance: Noted that a memo with a copy of the proposed ordinance that
would require a vote before TVWD could use the Willamette River as a drinking
water source was expected to be considered by the TVWD Board during their June
13 meeting.
G. Miscellaneous Work Groups and Task Forces: Most all of the water related work
groups and task forces have been on hold during the legislative session so there
was nothing to report.

To Whom it May Concern:
•
In conformance with the requirements of OAR 333-061-0040,the results of our Lead and Copper Rule
monitoring for the first period of 2001 are submitted in the attached technical memorandum.
Monitoring was conducted as described in our joint monitoring proposal submitted May 14, 1997. and
approved by Oregon.Health Divisionintheir letter of June'23, 1997. As described inthe plan, all water
systems using Bull Run water as their sole or major source of supply are considered as a single large system
for compliance with Lead and Copper Rule monitoring requirements.
ill In summary, 144 samples were collected from Tier I homes throughout the participating systems' service
areas. Samples were collected between May 10 and 22, 2001.The 90th.percentile values for the Joint
Monitoring results are as follows:
Lead 0.017;mg/L
Copper 0.61 mg/L
Distribution results are submitted separately on new forms designed to match the new OHD forms and
reporting protocol.. The Bull Run system pH ranged from 7.4 to 7.6pH units. Thesedata show pH
adjustment of the Bull Run Supplywas effective in maintaining a pH of 7.0 or greater in the distribution
system. -
In June of 1998. OHD set entry point water quality parameters for the Bull.Run system. Although these data
are reported monthly in a separate report,it should be noted that excellent treatment control has been
maintained and control has improved since corrosion treatment began.

area. Since the monitoring plan is population-based these systems do not collect samples. '
All samples were collected from Tier I homes sampled in 1992. All of the Portland Water Bureau
homes sampled in September 2000 were resampled this time except eight. Portland Water Bureau
homes 20, 28, 85, 103, 110, 111, and 119,were°replaced by homes 11,,27,84, 104, 106, 114, and 125
from the Tier One samplingpool.Home 176 replaced Tualatin Valley home 139.Portland Water
Bureau sampled 14 extra homes, and TVWD sampled one extra home that was not sampled in
September 2000. Otherwise,participating utilitiessampled the same homes in May 2001 as were
sampled in September 2000.
Home,tap samples were collected between May 10 and May 22, 2001. Directions provided to
customers specified first draw one-liter samples drawn from the cold water kitchen tap,unless there
was an inline filter on the kitchen tap that could not be bypassed. Complete instructions provided to.
the resident are shown in Appendix 1. We offer this as demonstration that the water system informed
residents of the proper sampling procedures according to OAR 333-061-0036(2)(e)(B)(ii)., The
customer filled in the time and date of sample collection and the time and date of last water use. No
samples were included which had less than a six hour standing time:.
All but seven samples were,noted as collected from the kitchen tap. All seven were collected from
bath taps:. Five Portland home samples did not meet the required standing time,two were less than six
hours,two were greater than eighteen hours,and one did not specify the standing time and was unable
to be contacted.

The Portland Water Bureau Water Quality Laboratory performed analyses. The 90th percentile lead
and copper values were determined as described in 40 CFR 141.80 and clarified by the Lead and
Copper Rule Guidance Manual (1991). In this round of sampling there were 144 samples. As the •
guidance manual states, "Interpolation of lead and copper levels may be necessary in some cases to
determine system performance at the desired frequency. If the 90th percentile value is represented by
the sample position other than an integer, (e.g.0.9 x#samples=17.3), then the 90th percentile value
must be found by interpolating the results of the lower and higher samples (e.g. the 17th and 18th results
in this case)." In this round of sampling, the 90th percentile values reported are based on sample
position 129.6, and the value was found by interpolating between positions. 129 and 130.
Results .
Tap Monitoring for Lead and Copper
The lead and copper results from tap sampling at the 144 tier I homes sampled in May 2001 according
- the Joint Monitoring Plan are shown graphically in Figures 1 and 2. The lead and copper raw results
are shown in Table 3a and 3b and briefly summarized below. Addresses for the 144 homes are shown
in Appendix 2. •
The 90th percentile result for lead exceeded the action level and the 90th percentile result for copper
was below the action level for this round of monitoring. The lead 90th percentile result was 0.017
mg/L(action level=0.015 mg/L); the copper 90th percentile result was 0.61 mg/L(action level=1.3
mg/L). •

• Conclusions
Based on the data submitted, the following conclusions are offered:
• For the ninth consecutive six-month monitoring periods following the installation of corrosion
treatment the 90th percentile copper:was below the copper action level.
• In May 2001,the 90th percentile value for lead was 16.7`ug/L.
• Although the copper level after treatment has been very stable,lead levels are more variable and
remain close to the action level.

Memo to: IWRM Water Managers Group
From: Tom VanderPlaat— CWS Senior Special Project Manager
Subject: IWRM Water Supply Project Progress Report.
1. Water Supply Feasibility Study RFP— On July 12, two proposals were submitted
for the Study.
Proposals were received from the following consulting firms:
1. Camp, Dresser, McKee (CDM); HDR; Shapiro; FishPro;Jeanne Lawson
Assoc.
2. Montgomery Watson Harza (MWH), URS;CH21vIHill;Norton, Arnold &
Janeway
The budget for the Proposals were $680,000 based on 6,812 hours for the CDM and
$732,000 based on 6,892 hours for the MWH.
`' • The proposals were distributed to the Consultant Review Team to review and
evaluate. The team members are: Ed Wegner,City of Tigard; Mike McKillip, City of
Tualatin; Dave Nelson, BOR; Dave Jarrett, Oregon Water Resources Dept;John
McDonald, Tualatin River Watershed Council; Eldon Mills, ESM Consulting; Sheri
Wantland, Bruce Cordon and myself of.Clean Water Services.
The Review Team met on July 18 to review and discuss the proposals. The main
evaluation criteria are experience, work plan, costs and adherence to proposal
instructions. Both proposals were well done,and included staff with the relevant
experience, however, both exceeded the anticipated funding resources. Due to
several issues, the review team could not arrive to a decision as to a recommendation
to the Water Manager's. It was decided to conduct interviews with key staff from
each proposal team. A list of questions with additional evaluation criteria was
developed to address the issues related to each proposal. The interviews were
conducted on July 26 with each team. The interviews provided for the review team
the opportunity to gather further information and meet the key consulting staff.
Following the interviews, the review team discussed the two proposals. The review
team was to meet prior to this meeting, however, in the days following the interviews,
both consultants contacted me and suggested willingness be,flexible on approaches of
, the Study. Given the concerns with the issues related to funding and clarifications of
tasks and work plan processes, I am recommending that we ask the consultants to
submit supplemental proposals. The supplemental proposals will need to address
various elements and include a requirement not to exceed the funding limit of
//g4r .
$650,000. This level of funding allows for funds for a portion of CWS project •
management and other possible issues that may arise during the Study process. This
approach will provide the consultants and the Partners the opportunity to clarify and
fine tune the Study issues. I intend to allow only a couple of weeks for the proposals
to be resubmitted. I would like to get a better grip on this project and keep it within
our resource limits.
The assistance of the Review Team has been great and is greatly appreciated. They
have invested lots of time and effort in providing excellent reviews and evaluations
during the process. I will still need their further assistance to evaluate the
supplemental proposals.
2. joint Funding Agreement for Water Supply Feasibility Study. The final signed
Agreements have been sent to all of the Partners. One of the next steps is to develop
of a budget and payment schedule for the Study
3. Public Meetings—At the July meeting of the Tualatin River Watershed Council, the
chair started an initial discussion of public issues related to the Study. Sheri and I
will be attending the Council meeting tonight to assist with gathering any additional
issues.
