UTILITY ADVISORY COMMITTEE MEMO
DATE: July 10, 2000
TO: UTILITY ADVISORY COMMITTEE
FROM: Jeff Young, Wastewater Treatment Plant Superintendent
SUBJECT: BIOSOLIDS LAND APPLICATION AND EQUIPMENT
Summary: The City has applied for a permit from the Department of Ecology (DOE) to land apply
biosolids from the WWTP in accordance with their regulations. Staff has reviewed a number ot
options and find that the most cost effective solution is to own and operate our own equipment. Staff
has found used equipment that will meet our needs. The equipment will be available for purchase
in the fall of 2000. The City will need the services ora contractor to apply the biosolids for the year
2000.
Recommendation: The UAC recommend to the City Council that the Public Works
Department pursue Option No. 1, utilizing Gagnon and Sons as our contractor for 2000 and
Option No. 3, to purchase used equipment when it becomes available from the City of
Bremerton for use in subsequent years.
Background/Analysis.' The City is required to make beneficial use of biosolids from the
Wastewater Treatment Plant. Staffbelieves that land application will meet this requirement
while keeping costs to a minimum.
On April 10, 2000 the City submitted the General and Site Specific Biosolids Application permit
to the United States Environmental Protection Agency (USEPA) and Department of Ecology for
approval. We have proceeded through the State Environmental Policy Act (SEPA) comment
periods with very few comments. The USEPA Region 10 has approved the City's plan to land
apply biosolids. The DOE is currently processing our application and will respond to the City
sometime in early July. The City can start applying the biosolids as soon as we receive the DOE
permit and after the first hay crop is harvested from the area where the biosolids will be applied.
The City is currently storing the biosolids in the compost facility at the landfill. Them is about
four months storage remaining. The biosolids need to be applied before the fall rains begin to
avoid damaging wet fields.
Staff has investigated the possibility of sharing equipment through both the Northwest Biosolids
Management Association and several treatment plants. Staff did locate a used, truck mounted
spreader that will meet the City's needs at the City of Bremerton. This unit will be available in
late August or September.
Staff also contacted application firms and have received four quotes. Separate quotes were
obtained for the land application and for transporting the biosolids from the City storage site.
The land application process is expected to take two weeks to complete.
OPTION #1: CONTRACTOR APPLICATION AND/OR TRUCKING:
Contractor Land Application Transportation Total Project
Rates Rates
Gagnon and Sons Farm $ 1,620 $ 2,880 $ 4,500
R.P.Cebriy Ltd. $ 6,275 (Can) $11,897 (Can) $18,172 (Can)
Fire Mountain Farms Inc. $16,550 $11,500 $27,050
Behrman Transport, Inc. $18,000 $10,500 $28,500
OPTION #2: CITY STAFF APPLY WITH NEW SPREADER: The best price obtained
on a rent/purchase option was $19,500. This includes the purchase of a new spreader and rental
of the other equipment for a month.
OPTION #3: CITY STAFF APPLY WITH USED TRUCK MOUNT SPREADER: This
would cost approximately $5000 and is already set up for field work. We would need to use a
loader from the Corporation yard or Landfill for one to two weeks.
Staff has analyzed the options and recommend the following:
· For the year 2000, utilize the services of Gagnon and Sons for the land applications and
transportation for a total of $4,500.
· Pursue Option #3 for 2001. We would have to wait until the Bremerton truck mounted
spreader becomes available (August or Sept. 2000) and then purchase it for our own in-
house program.
Option #3 as a long term solution provides the City with better control of the program, allowing
the field application to be done at times that are convenient to the City. It also provides better
control over meeting the State and Federal regulations required for land application of biosolids.
Funding for the 2000 and 2001 options would come from the Wastewater annual budget.

UTILITY ADVISORY COMMITTEE MEMO
DATE: July 10, 2000
TO: UTILITY ADVISORY COMMITTEE
FROM: Dale A. Miller, Recycling Coordinator ~kcc/
SUBJECT: Revisions to Ordinance 13.56.060 Landfill Disposal Area Regulations
Summary:. The Solid Waste Division needs to remove contaminants from yard waste being
delivered to the Landfill Site to make Class A compost. Presently, Landfill users are requested to
voluntarily remove contaminants prior to unloading their yard waste at the site. Revisions were made
to Ordinance 13.56.060, Landfill Disposal Area Regulations, to require all users to remove
contaminants prior to unloading at the Landfill.
tecommendation: Recommend to the City Council to approve the revised Ordinance 13.56.060
regarding removal of contaminants from yard waste.
Background / Analysis: Contamination in yard waste collected at the curb or delivered to the
Landfill Site must be eliminated in order to make Class A compost. Revisions to Ordinance
13.56.060, Landfill Disposal Area Regulations, are necessary to prohibit contaminants such as
plastic, construction materials, and garbage from entering the yard waste disposal site at the landfill.
The revisions to the ordinance will require commercial and private users of the Landfill Site to
remove contaminants from their loads. This must be done prior to unloading at the designated yard
waste site. This ordinance will become effective October 1, 2000.
City staff is negotiating with Waste Management to voluntarily amend the current contract to require
them to remove contaminants from the yard waste they collect in Port Angeles. There will not be
any additional rate increase for the contaminant removal. The City requested Waste Management
tO respond by July 15, 2000.
City staff will make recommendations to modify the yard waste collection program at the completion
of the current contract, December 31, 2002. Staff will be recommending advertising for Requests
for Proposals for the curbside recycling and yard waste programs to include;
1. Subscription yard waste collection Residents that choose to have yard waste collection
would pay for the cost of the service.
2. Contractorprovidedcontainersforyardwaste. All yard waste would be placed into the
container for collection..

UTILITY ADVISORY COMMITTEE MEMO
DATE: ~L¥ ] 0, 2000
TO: UTILITY ADVISORY COMMITTEE
FROM: James L. Harper
SUBJECT: Cresthaven Service ConversIon Cost Assistance ~
The City Council on September ?, 1999 approved assisting Cresthaven customers in
Summary;.
the conversion of their oYerhead services to underground at a cost up to $1,000 per service. Thc bids
received for the conversions were approximately 50% higher than anticipated. The City has received
conceraed calls from many of the customers and a written request signed by two of thc customers
for additional assistance due to the high bids.
Recommendation: UAC recommend the Cit~ Council authorize full reimbursement of
customer conversion costs.
Background / Analysis: The City Council on September 7, 1999 approved a plan by which all
rear lot landlocked facilities would be replaced wSth underground facilities in street right of way.
Included was up to $1,000 financial assistance to the customers with overhead services who must
convert to underground. The Cresthaven area includes sixteen (16) overhead customers in three of
thc eleven landlocked areas. The remaining landlocked areas include 82 overhead customers which
should be assisted to the same extent as those in Cresthaven. Southwood area which is also budgeted
for constmction this year contains 34 of these 82 remaining customers. The other landlocked areas
are currently in the CFP for construct/on in 2001.
Staff has made every effort to ensure all Cresthaven customers were thoroughly informed well ahead
of time of their requirements for this project. Public meetings were held on February 17 and 22
which were publicly advertised and a personal letter of invitation was sent to each customer in the
project area. At these meetings it was very carefully explained that those having overhead service
must convert their service to underground, and that the City Council had very graciously agreed to
assist in the cost up to a maximum of $1,000. It was also explained at that time that they must
contract with their own electrician but the City as an assistance to them would obtain estimates that
they may utilize or obtain bids from whatever electrician they chose. All questions were answered
and we indicated that the City contribution was expected to cover the cost of most of the
conversions.
Arrangements were made with four electrical contracting firms to provide bids for the conversion
of the 16 customers and they were to visit the sites between May 19 and May 26. The customers
were informed that the electrical contractors would be visiting their homes during the assigned time
frame and that the estimates would be forwarded to them shortly thereafter. In this letter they were
again reminded that they must contract for the conversion and that the City would reimburse them
the lesser of $1,000, the lowest estimate or the invoiced cost. Only two of the four electrical
contractors Angeles and Olympic Electric submitted bids. The bids were higher than expected by
approximately 50 - 65%. The two bids per customer were distributed by letter on June 20.
The low bids as received result in a cost to the City of $15,782.20 and additional cost to 13 of the
16 customers ranging up to $1,331.44 for a total ors 8,861.06. If the City should choose to increase
its assistance up to $1,500, it would result in a cost to the City of $21,098.30 and an additional cost
to 6 of the 16 customers ranging up to $831.44 for a total of $ 3,544.96. The cost for all service
conversion is $24,643.26 for an increase of $8,861.06 if the City should choose to pay it all.
This matter is being referred to the UAC for consideration of increasing the City's contribution
above the authorized $1,000.

Dear Mr. Quinn;
This past week Cresthaven homeowners received bids that had been submitted by two
contractors to the City for the "Cresthaven Rebuild Project". After talking with our
neighbors, we found that we were not the only ones alarmed by the amount of each
homeowners bid. We were all under the impression, from the meeting held a couple
months back, that the $1000 allowed by the City for reimbursement, would easily cover
the conversion expense:
We have a couple concerns. One of the contractors told us that they were unsure why
the City did not ask for a bid on the entire project, which would have reduced the cost for
everyone involved. The estimator said that since they did not know if they would get one
job or ten jobs, the estimate would he much higher. Later we were told that the City
couldn't ask for a single bid since each homeowner is responsible for the conversion
expense and the City was just reimbursing for those expenses and that we could have, as
a homeowners group, asked these companies to bid on the whole project. However that
was never mentioned to any of the homeowners nor did we realize that it was each
homeowner's responsibility. In addition, homeowners have akeady paid for electrical
hookups once and shouldn't have to pay for a second hookup since it is not the
homeowners requesting this change.
We would request that the Utility Advisory Committee increase the allocated amount for
reimbursement by approximately $7600 to cover all associated expenses.

DATE: July 10, 2000
TO: UTILITY ADVISORY COMMITTEE
FROM: Stephen Sperr, Utility Engineer
SUBJECT: Ground Water under the Influence of surface water (GWI) Action Plan
Submission to Department of Health (DOH)
Summary_:. The City's water source was designated by the DOH as Ground Water under the
Influence of surface water (GWI). Due to this designation it is required by the DOH to submit an
Action Plan for approval that details the steps that will be taken to comply with EPA's Surface
Water Treatment Rule. The attached plan is provided for review and discussion.
Recommendation: Recommend that the City Council 1) approve the Action Plan and 2)
authorize the Director of Public Works and Utilities to negotiate and sign the Bilateral
Compliance Agreement (BCA) contained within the Action Plan, and approve any modification
to the BCA that does not obligate the City to expenditure of additional funds beyond that
required to comply with the initial BCA.
Background / Analysis: On April 25, 2000 the DOH designated the City's water supply
source, a Ranney Collector, as Ground Water under the Influence of surface water (GWI). The
City has therefore been directed to submit to DOH an Action Plan by July 25, 2000, under the
Environmental Protection Agency's (EPA) Surface Water Treatment Rule. The Action Plan
must address the steps that the City will take to bring it into compliance with the Surface Water
Treatment Rule.
The City has been working with its consultant, CH2M Hill, to develop the Action Plan. The
Action Plan, a copy of which is attached, outlines the steps that the City will take in the next five
years that will result in either (1) the construction of a new water treatment facility, or (2)
changes in the way the City disinfects and operates its existing Ranney Collector/source fac. ility
that will not require a new water treatment facility.
The City will be actively pursuing those options, outlined in the Action Plan, that may result in
avoiding the construction ora new water treatment facility. However, the DOH requires that the
City assume that the water treatment facility will be needed and proceed with evaluating
treatment options, pilot testing, etc. at the same time it pursues its other options. The impacts

that the removal of dam(s) on the Elwha River are also addressed in the Action Plan, and DOH
acknowledges that it is likely to impact the schedule included in the Action Plan.
Parts of the Action Plan will likely have to be revised to incorporate comments from the DOH.
The Bilateral Compliance Agreement (BCA) is one part of the Action Plan that will likely
require some further negotiation with the DOH. As on a previous BCA with the DOH (related to
copper and covering the City's water storage reservoirs), the Director of Public Works and
Utilities should take the lead on behalf of the City in negotiating the BCA and signing on behalf
of the City.
Attachment: Executive Summary of GWI Action Plan
GWI Action Plan w/Bilateral Compliance Agreement (DRAFT
N:\PROJECTS\20-18\UAC7_IOA.WPD
Executive Summary of Action Plan for GWI Compliance
The City of Port Angeles was formally notified by DOH in an April 25, 2000 letter that its
Elwha Ranney collector supply source had been classified as GWL Classification as a GWI
source requires that the City comply with more-stringent surface water regulations. The
letter cited WACs requiring the City to prepare an "Action Plan" outlining its compliance
pursuit of filtration as the basis of a new treatment system. WAC requirements state that
the City is to have implemented filtration within 18 months of GWI classification. DOH
acknowledges that this time-frame is unreasonable and is willing to engage the City in a
bilateral compliance agreement (BCA) to allow the City to pursue evaluation, planning,
design, and construction of a filtration system in a more appropriate timeframe.
DOH allows the City to pursue GWI compliance strategies other than filtration as long as
they are pursued on a "parallel track" to the pursuit of filtration and do not result in
delaying the pursuit of filtration. However, it should be noted that DOH does not believe
that pursuit of these alternative strategies are likely to result in ultimate DOH approval.
DOH is strongly in favor of implementation of a DOH-approved filtration technology with a
record of effective historical performance. Still, DOH staff have acknowledged that
implementing filtration will be very costly and may not provide greater public health
protection than an alternative compliance strategy. DOH has stated that, should the City
pursue an alternative GWI compliance strategy, it will be incumbent upon the City to state
its case to DOH and demonstrate to DOH's satisfaction that it can fit within the framework
and requirements of existing drinking water regulations.
The Action Plan includes a detailed summary of each of the steps forming the "critical path"
schedule leading to filtration. The schedule is reflective of a discrete, step-wise progression
of compliance tasks designed to ensure that DOH concurrence and approvals are in place
throughout the course of the project and that the City's costs related to uncertainties of such
approvals is minimized. In general the activities the City will need to undertake in its GWI-
compliance pursuit of filtration are: 1) preliminary evaluation of filtration alternatives, 2)
testing (pilot and/or bench-scale) of preferred filtration alternative(s), 3) preliminary design
(report to DOH), 4) final, detailed design (including bidding documents), and 5)
construction,
In addition to describing the City's implementation schedule for pursuit of DOH-approved
filtration, the Action Plan identifies and briefly describes three alternative GWI compliance
strategies that the City intends to pursue: 1) demonstrate the natural filtration capabilities of
the Elwha Ranney collector and its associated gravel pack (to substitute for a filtration
plant), 2) demonstrate that the City can meet the regulatory-established criteria to remain as
an unfiltered surface water (while providing additional disinfection), and 3) clean or
modify the existing Ranney co]lector to reduce its surface water influence and re-conduct
GWI testing achieve a groundwater classification. The details of these alternative
compliance strategies are less clearly defined in the Action Plan than is the pursuit of
filtration. The City's pursuit of these alternative compliance strategies will evolve to some
degree in the next few weeks and months as the City collects data establishing to determine
the viability of these alternatives.
The Action Plan includes a draft BCA as an appendix for use by DOH to prepare the
binding BCA that will be negotiated over the next 2 months by the City and DOH. The draft
BCA includes detailed requirements for pursuit of filtration and does not specifically
address requirements for alternative compliance strategies. As stated above, the City is free
to pursue alternative GWI compliance strategies as it wishes, it will not be required to do so
by DOH, and will not be held to a schedule for such alternative pursuits.
The BCA is a relatively simple document, prepared in a standard format provided by DOH,
that states what tasks the City is required to do and the timeframes in which is required to
accomplish them. The second part of the BCA is a series of acknowledgments and
agreements by DOH of its role in the BCA. In some cases, these acknowledgments and
agreements serve as caveats that could lead to termination or re-negotiation of the BCA
depending on the results of the City's compliance activities and the activities of the Elwha
dam removal process.

(DOH) classification of the City of Port Angeles (C,i~ Elwha Ramney collector as a
groundwater under the direct influence of surface water (GWI). This Action Plan is
prepared in conformance with the requirements of WAC 246-290-670 (3). In addition, this
Action Plan includes a CT Compliance Plan for interim disinfection until filtration facilities
are installed or other system modifications deemed acceptable to DOll are implemented
bringing the Elwha Ranney collector into compliance with the Surface Water Treatment
Rule. The CT Compliance Plan is prepared in response to the DOH's specific direction to
address the requirements of WAC 246-290-672 and 674.
2. Critical Path to Filtration
The City intends to identify and evaluate alternative filtration technologies for its Elwha
Ranney collector supply. The existing Ran.ney collector has many years of demonstrated
effectiveness for removing suspended solids and turbidity from the Elwha river and will
serve as an essential element of the City's future supply intake system.
A proposed schedule of the City's GWI compliance activities is presented as Figure 1. The
schedule outlines the activities related to implementation of a filtration solution that forms
the overall critical path of the project. Within the timeframe established by the critical path,
the City's pursuit of alternative GWI compliance activities are also scheduled. The sections
below describe each of the critical path activities while GWI compliance activities related to
other alternatives are described in Section 3.
It should also be noted that the City will need to obtain additional loan or grant funding for
the more costly phases of the project such as design and construction. Thus, the schedule
for these activities might need to be shifted if such funding is not obtained in time for these
phases.
2.1 Action Plan and Bilateral Compliance Agreement
In response to DOH's GWI Designation letter to the City, dated April 25, 2000, the City has
submitted this proposed Action Plan for DOH approval. A draft Bilateral Compliance
Agreement (BCA) is included as part of this Action Plan as Appendix A. The draft BCA is
based on the content of this Action Plan and is proposed to serve as the binding agreement
for all of the City's GWI compliance activities. The Action Plan and draft BCA were
prepared in recognition of the need to proceed in a step-wise fashion that allows adequate
Fane for the effective completion of specified tasks, DOH review, and response to DOH
review comments.
2.2 Preliminary Evaluation of Filtration Alternatives ',~, ~,~
The City shall perform a desktop evaluation of suitable filtration altemat~t~s" for the
purpose of selecting one ore more technologies for detailed study and development of
design criteria. A report describing this preliminary evaluation will be submitted to DOH
for its approval.
2.3 Testing Protocol Report
In conformance with the requirements of WAC 246-290-676 (3) (b), a report describing
testing protocol will be prepared and submitted to DOH for its approval prior to
undertaking testing. The testing protocol shall be designed for the technologies selected as
part of the preliminary evaluation and approved by DOH. The testing protocol report will
include testing methods, timing, staffing, and evaluation criteria. The testing protocol is
anticipated to include either bench-sale testing, on-site pilot testing, or a combination of
both.
2.4 Testing Mobilization
Upon receipt of DOH review comments and approval of the testing protocol, the City will
obtain (purchase or lease) testing equipment, contract testing services, and schedule all
activities necessary for the testmg.
2.5 Testing of Filtration Alternative(s)
The City will test the City-selected and DOH-approved alternative(s) for a varying range of
water quality expected in the Elwha Rauney collector caisson. The treatment effectiveness
for water quality related to seasonal temperature variations, high river flows induced by fall
rains and spring runoff, peak pumping related to system demand, and late sttrnmer, low
river flows shall be tested. Depending on the content of the testing protocol and associated
DOH approval, testing will be conducted either continuously for a calendar year or
periodically to address all expected water quality conditions.
2.6 Testing Report
Upon completion of testing, a testing report will be prepared and submitted to DOH for
approval that includes a discussion of testing activities, testing results, and a
recommendation of the treatment teclmology to be further developed.
2.7 Project Report
Upon receipt of DOH review comments and approval of the test report, the City will
prepare a project report that will serve as a preliminary design of the facilities to be
designed and constructed. The project report will be prepared in conformance with
246-290-110, Project Report. The project report will reference work products previously,
completed and approved by DOH and include discussion of other applicable evalu~s
such as facility siting, design criteria, and operations considerations. ~.~'~
.......
2.8 Design of F tra~ on ~-acm~y ~,,,\ 'v-
Upon receipt of DOH review and approval of the project report, the Cityxw, il,~r~pare a
design of the filtration facility. Bidding and contract documents will also be'prepared to
permit a regulatory-compliant process of selecting a contractor for the construction project.
2.9 Contract Bidding
Upon receipt of DOH review and approval of the design of the filtration facility, the City
will advertise and competitively bid the construction contract in accordance with state and
federal (if federal funding is involved) bidding requirements.
2.10 Contract Award and Execution
The City will award and execute the construction contract for the filtration facility in
accordance with the requirements of bidding and contract documents, established City
procedures, and approval of the City Council.
2.11 Construction, Startup, and Testing
The City will monitor and inspect the work of the contractor throughout construction,
startup, and testing. Prior to delivering filtered water to the City's customers, a standard
DOH construction report will be prepared and stamped certifying the filtration facility has
been constructed in accordance with the design documents. In addition, the City will
monitor the contractor's efforts demonstrating plant performance compliant with design
requirements.
3. Other GWI Compliance Alternatives
While it is actively pursuing development of a filtration facility, the City will also pursue
other GWI compliance activities, as described below.
3.1 Natural Filtration
The City is currently working on the development of a GWI compliance strategy based on
the natural filtering that is occurring between the Elwha river surface water and the water
entering the Elwha Rarmey collector. Development of this strategy I~d~pendent on t e
results of a couple of key mitial data points being collected or soon to be collected by the
City.
At this point, the City has already collected a single set of microscopic particulate analysis
(MPA) samples (collected simultaneously) from the river and the Elwha Ranney collector.
The laboratory results are attached as Appendix B and reflect 3.1-1og and 3.4-1og removals
of diatoms and other algae.
These promising results will be followed up in the next month or so with several days of
preliminary particle-count testing. The particle-count testing will be conducted on Elwha
river water and Elwha Ranney collector water in several size categories, including those for
giardia, cryptosporidium, and viruses. The City considers this initial particle count testing
period to be a preliminary testing phase to evaluate the filtration capacity of the existing
Ranney collector gravel pack.
Upon completion of preliminary particle count testing, the City will submit the results to
DOH for its review. If testing results are favorable, the City will prepare a testing protocol
report to demonstrate the natural filtration capabilities in an effort to obtain removal-credit
for Giardia and viruses.
3.2 Filtration Avoidance
The City will pursue the avoidance of filtration in conformance with the requirements of
Part 6, Subpart D of WAC 246-290 (- 698 through -- 696). Preliminary activities related to
this pursuit will be to establish the City's capacity to meet the water quality criteria
requirements to avoid filtration. Assuming the City is able to establish capability to reliably
meet these criteria, it will develop a proposal for compliance with the watershed control
criteria requirement.
The schedule for developing this filtration avoidance proposal is less well-defined than the
schedule for developing the GWI compliance approach based on filtration. The City
proposes that the specific activities of this schedule requirement remain undefined other
than the general timeframe presented for this alteruative presented in Figure 1.
3.3 Modification of Elwha Ranney Collector
The City intends to evaluate options for physical, operational, and other modification of the
Elwha Rauney collector to reduce the water quality cormection it has with the Elwha river.
The City proposes to leave the schedule and scope of activities related to this alternative
undefined other than what is presented in Figure 1.
At this time the City has not had enough time to evaluate the potential effectiveness of all
possible modifications to the Ranney collector. However, one alternative the City intends to
pursue is inspecting the Rauney collector caisson and laterals using a video camera to detect
the presence of biological growth. The City has obtained information from the Ranney
collector manufacturer indicating that such growth, perhaps including diatoms and other
algae, has been shown to occur in other similar collectors. If such growth is shown to be
4
present, the City would undertake a thorough cleaning pf, oc~ss.to~remOv~t~'rg'Towth nd
subsequently collect an additional sample for MPA testing. The results of the testing would
then be submitted to DOH for its review and direction on an appropriate course of action.
4. Impacts of Elwha Dam Removal
As DOH is aware, the National Park Service has begun preliminary activities related to the
ultimate removal of the Elwha dams. The National Park Service has purchased the dams, is
subcontracting their operation, and has been appropriated money to plan and design their
removal as well as mitigation facilities for downstream water users.
The National Park Service is underway with planning the mitigation facilities to be
designed and constructed for the City to mitigate impacts of dam removal to its municipal
and industrial water systems. Preliminary planning meetings reflect the anticipated pursuit
by the National Park Service (through its alliance with the Bureau of Reclamation) of a
treatment facility that includes filtration designed to meet current and anticipated future
drinking water regulations. Filtration is a necessary component of mitigation facilities for
the City because of regulatory requirements and because of the expected increase in total
suspended solids and turbidity as well as other contaminants in the City's Elwha Ranney
collector caisson.
Although a project schedule has not been prepared for the design and construction of the
mitigation facilities for the City, they are expected to be ready for service within the next 4
to 6 years. The actual schedule will depend on the timing of additional federal funding
appropriations for removal of the dams and construction of the mitigation facilities.
Additionally, environmental permitting (if required) may also impact the schedule.
Removal of the Elwha dams carmot take place until impacts on water uses of the City and
other users downstream of the dam have been mitigated.
In recognition of the ongoing planning and development of water system mitigation
facilities for the City, there may be a point in the next year or two when the specific supply
and treatment mitigation facilities have been selected and approved by the appropriate
agencies, including DOH, and the schedule for design and construction of these facilities
becomes more firmly established. When that point in time is reached the City's GWI
compliance activities ma~ need to be reevaluated in concert with DOH to assess the need to
alter the progression of those activities.
For example, it may not be financially prudent for the City to construct GWI compliance
facilities that would not be suitable to treat the range of raw water quality parameters that
are anticipated after dam removal. It may make more sense for the City and DOH to more
closely align the City's GWI compliance activities with the progression of mitigation
activities established as part of the Elwha dam removal process. This possible realignment
is based on the current assumption that the mitigation facilities that result from the Elwha
dam removal process will be compliant with the GWI-initiated treatment requirements for
which the City is obligated.
, DRAFT jl
Prior to any such realignment the City intends to focus its p~opOsed-G--WI-~mp}i~--~ /
activities, in concert with DOH guidance and approval, on solutions based on current
supply conditions and facility configurations.
In the absence of dam removal, it is prudent for the City to focus on treating the Rarmey
collector supply which has a long history of producing excellent water quality. The City
has water rights for this supply and existing supporting infrastructure as well. Continued
use of the Ranney collector supply clearly would result in the minimum additional
treatment and be the most cost-effective for the City. Impacts resulting from dam removal
have been established to be the responsibility of the federal government.
5. CT Compliance Plan
The City's Elwha Ranney collector facility includes a gas chlorine system lo provide a
chlorine residual in the distribution system. The City has historically added chlorine at the
Rapmey collector at a concentration of 0.4 rog/L, which is enough to maintain a chlorine
residual in the western part of the distribution system. The City operates four other re-
chlorination facilities throughout its system on the outlets of its storage tanks to maintain a
chlorine residual throughout the entire distribution system. The chlorine facility at the
Elwha Ranney collector will be used to comply with the CT requirements imposed by DOH,
as described in the following sections.
5.1 Interim Requirements
The City intends to comply with the interim disinfection, monitoring, and reporting
requirements established by DOH until its future treatment system is ready for service. A
copy of these DOH requirements is included as Appendix C.
5.2 City's Proposal to Comply with Requirements
A key element of the DOH-imposed interim disinfection strategy is the requirement for 2-
log (99%) inactivation of Giardia larnblia cysts prior to the first customer served by the
system. This element presents the only significant challenge for the City because there is
limited volume in the existing supply pipeline to attain the required chlorine contact.
Compliance with the other disinfection treatment, monitoring, and reporting requirements
presented in Appendix B will present no difficulty for the City and do not warrant further
discussion. The remainder of this section addresses the City's efforts to comply with the 2-
log inactivation requirement.
5.2.1 Increase Dosage and Isolate Supply Pipeline
The City proposes to comply with the 2-log inactivation requirements by increasing the
chlorine dosage at the Elwha Ran_ney collector, thus elevating chlorine concentration in the
24-inch diameter supply pipeline. The supply pipeline will be isolated from customer
DRAFT
services for up to 25,171 feet from the source to attain the re~tii~ect CT'~Til~i~hs~-
concentration x time). Existing line valves connecting the supply pipeline to the
distribution system that are currently open will be closed to create the isolation. II, ese
closures are possible because in most cases the distribution system is either connected
exclusively to an 8-inch diameter pipeline that is parallel to the 24-inch diameter supply
pipeline or to both the 8-inch diameter distribution main and the 24-inch diameter supply
pipeline.
There are two connection s along the supply pipeline that cannot be easily isolated by
simple valve closure, but instead must be addressed differently. These two connections are
addressed later in this CT Compliance Plan.
5.2.2 Sampling Locations for Measuring Chlorine Concentration
The City recently installed three sampling locations along the Elwha supply pipeline. A
map of the supply pipeline and key sampling and other locations discussed herein is
presented in Figure 2. Sampling Stations No. 2 and 3 will be the primary sampling
locations for establishing CT compliance). The City will select which sampling station
location to use depending on the time or year and level of demand. Accordingly, the City
will isolate the supply pipeline to the sampling station being used to establish compliance.
During times of the year when attaining the required CT is more difficult, Sampling Station
No. 3 will be used because of the greater contact time that is provided. During other times
of the year Sampling Station No. 2 will be used because it allows the supply pipeline east of
L Street to be connected directly to the distribution which substantially increases fire flow
capacity at the County Fair Grounds.
A portable chlorine meter will be used to measure chlorine concentration for establishing
CT compliance. The City currently monitors chlorine residual at the Elwha Rarmey
collector on a continuous basis. The City proposes to establish a relationship between
chlorine residual at the dosage point at the Elwha Ranney collector and at Sampling
Stations No. 2, and 3. Establishing this relationship will enable City staff to obtain the
needed chlorine concentration data for the daily CT computations by simply reading the
chlorine residual analyzer at the Elwha Ranney collector. The City will establish this
relationship over the course of a two-month period beginning in August of 2000. It will
then submit the relationship data to DOH to obtain its concurrence for measuring chlorine
concentration only at the Elwha Ranney collector.
5.2.3 Maximizing Actual CT
In recognition of the fact that natural waters exert a demand on chlorine that reduces its
concentration over time, the City must add more chlorine at the Elwha Ranney collector
dosage point to ensure adequate chlorine concentration at the compliance sampling stations
further downstream. In doing so, there is a higher concentration of chlorine in the
upstream end of the supply pipeline that, if quantified, can be incorporated into the City's
CT compliance computations.
City staff propose to collect chlorine residual data at an existing sampling point
approximately 300 feet downstream of the dosage point and at a newly-installed sampling
DRAFT
station, Sampling Station No. 1, at Milwaukee Dr. and W. 15th St. (14~371 feet downstream of
the Elwha Ranney collector) during the same three-month period discussed above. The
purpose of collecting chlorine residual data at these two additional locations is to establish
the chlorine concentration relationship between the five locations (1 dosage and 4
sampling). In essence, the decay rate of chlorine in Elwha Ranney collector water will be
established. This relationship will be used to take advantage of the fact that the
concentration of chlorine in the supply pipeline upstream of the Sampling Stations No. 2
and 3 is greater than that measured at these two locations. By establishing the approximate
decay rate of chlorine in the Elwha Ranney collector water, this greater chlorine
concentration will be incorporated into the City's daily CT computations. The City will
submit this three-month data to obtain DOH concurrence for accounting for this amount of
added CT.
An example is illustrated in Figure 3 of how quantifying chlorine decay in the Elwha
supply pipeline will help the City in achieving higher computations of actual CT. The area
under the dashed line represents the amount of CT achieved by simply multiplying contact
time in the supply pipeline by the chlorine residual at the end of the isolated pipeline length
(in this case, the intersection of S. D St and W. 16th St). By establishing the relationship
between chlorine concentration at the various sampling locations, the additional area
between the dashed line and the chlorine decay line in Figure 3 can be computed. If the
shape of the chlorine decay curve is similar to that shown in Figure 3, the shape of this area
can be approximated by a triangle which would simplify computation of the additional,
chlorine contact time.
Using the example presented in Figure 3, the additional actual CT provided by the system
would be computed as the average of 1.0 mg/L and 1.36 mg/L (measured at the existing
sampling station to account for the initial, more-rapid decay of chlorine concentration)
subtracted from 1.0 mg/L with the resulting concentration multiplied by the residence time
in the supply pipeline, 92 minutes assuming a potential high flow of 10 mgd in July through
September (see Table 1 as discussed in the next section). The result would be an additional
actual CT of 16.6 minx mg/L during these peak-demand summer months, which will have
a tremendous positive impact on the City's ability to demonstrate CT compliance during
this time of the year as well as other times when achieving CT compliance is more difficult.
Upon approval from DOH, the City will incorporate this additional CT into its daily CT
compntations.
5.2.4 Operational Control
Because CT requirements are affected by parameters such as temperature and pH, the City
will modify operational procedures of the Elwha Rarmey collector pumps, as necessary, to
avoid excessive flow through the 24-inch diameter pipeline to the system. The City cannot
control temperature and pH, nor can it change the available volume for chlorine contact in
the supply pipeline; thus, controlling flow will be the primary option ensuring the required
2-log CT requirement is met at all times. An alternative element of control the City may
choose to employ, if customer response is not adverse, is to further elevate chlorine dosage
at the Rarmey collector.
DRAFT
To assess its capacity to meet the 2-log inactivation requirement the-Cityx:omp~__~ ~,.~
predicted CT requirements and predicted actual CT values for the 25,171-foot length of 24-
inch diameter supply pipeline for each month of the year. Compliance with CT
requirements is demonstrated by dividing Ctrequired by CTacm~ and obtaining a value of 1.0 or
greater. A summary of these computations is presented in Table 1. The parameters
included in Table 1 are described as follows:
· pH: The pH used in Table 1, 7.5, is considered to be an average of pH values that
have been measured in the past. Higher pH values may require the City to increase
chlorine dosage rates and/or restrict flow to the system. Lower pH values will
make it easier to meet the required CT.
· Ch: Chlorine is a variable in the formula for computing the required CT. The City
plans to meet CT requirements throughout the year with a chlorine concentration at
the Sampling Station No. 3 of 1.0 mg/L. To achieve a 1.0 mg/L concentration at the
sampling point, the City expects to add chlorine at the Ranney collector at a dosage
rate of approximately 1.4 mg/L. As stated, increases above 1.0 mg/L at Sampling
Station No. 3 may be necessary during some times of the year depending on the
operational procedures employed by City staff.
· Temp: The temperatures shown in the table are considered to be low temperatures
for each month. Low temperatures were used in the Table 1 example because CT
requirements are more difficult to meet when temperatures are low. Higher
temperatures will result in lower required CT values and make it easiei: to achieve
the required CT. Thus, the temperature values in Table 1 represent a conservative
condition with respect to temperature.
· CTreq: The required CT is computed using the following equation for temperatures
above 50 C and is presented in units of minx mg/L.
CTreq = 0.308 x pH2-69 x C015 x L x 2(5-T)/m
Where:
CTreq = required concentration x contact time (minutes x mg/L)
T = water temperature (°C)
· C = residual chlorine concentration (mg/L)
L = log inactivation required
* Volume: Volume refers to the volume in the 25,171 feet of 24-inch diameter supply
pipeline. The City's Elwha supply pipeline is constructed of AWWA C151, Class 51
pipe, which has an inside diameter of 24.98 inches. This pipe diameter was used in
the computation in Table 1.
· Flow: Flow refers to the flow rate from the Elwha pump station. This operational
element will be the key control variable for the City during summertime peak
demand periods. As long as only one pump is operated (6 mgd), it is apparent there
will not be a problem achieving the required CT. However, when two pumps are
operated, they may or may not need to be throttled to restrict flow. The need for
throttling will depend on pH and temperature conditions at
not the City decides to increase chlorine concentration instead of throttling flow.
· Res Time: Res time refers to the residence time (chlorine contact time) in minutes in
the supply pipeline and is computed by dividing volume by flow.
· C12: As stated previously, chlorine concentration is a variable in the formula for
computing the required CT. However, the same chlorine concentration is also used
to compute the actual CT.
· CTact: The actual CT is computed by multiplying the residual chlorine concentration
at the sampling station by the residence time.
· Inactivation Ratio: The inactivation ratio is computed by dividing CTact by CTr~q.
Compliance with CT requirements occurs when the inactivation ration is 1.0 or
greater.
5.2.5 Two Un-isolated Connections
There are two locations along the 4-mile "isolated length" of the supply pipeline where
connections to residential customers and a municipal facility carmot be disconnected
without discontinuing service. The City proposes to address these two locations as follows:
· The first location is the connection to a group of 4 residences located on the Elwha
bluff overlooking the Elwha river (near the west end of the Elwha supply pipeline)
known as the Elwha Heights Water Association (EHWA). The City is currently
negotiating with the Dry Creek Water Association (Dry Creek) to transfer service of
these customers to Dry Creek. To effect the transfer, approximately 1,500 feet of 4-
inch diameter pipe needs to be constructed to connect these residences to Dry
Creek's system. Tliis transfer is expected to take several months for design and
construction of the main extension, obtaining needed easements, and formalizing an
agreement between the City and Dry Creek.
The City is also evaluating the possibility of providing adequate CT on an interim
basis using a small baffled storage tank for water being served to these residences.
· The second location is the connection to the City's landfill compost facility, which is
adjacent to the City's municipal landfill. The City's landfill is located just to the
north of the compost facility site but is supplied by water from another portion of
the distribution system that will have the required chlorine contact. The connection
to the compost facility serves a restroom with two sinks and two toilets, but more
importantly it supplies a fire hydrant for protection of the compost facility site. The
City proposes to post the restroom facility and the fire hydrant with signage
indicating that the water is non-potable while maintaining the non-potable uses of
the fire hydrant and the restroom. This location is restricted to the public. Only City
employees are permitted access to the site.
10
5.3 CT Compliance Schedule
As of July 25, 2000, the City is currently complying with the interim disinfection,
monitoring, and reporting requirements as established by DOH with the exception of the 4
residences of the EHWA. ~e City anticipates having transferred these customers to the
Dry Creek Water Association by December 31, 2000 or have implemented another strategy
that provides them with adequate CT.

1. Compliance with Existing Conditions: The Department acknowledges that Purveyor
will pursue, in addition to alternative strategies described in the Purveyor's Action Plan,
a GWI compliance strategy based on filtration of water from the existing Elwha Rarmey
collector, assuming the Elwha dams are not going to be removed. The Department
agrees to review Purveyor work product submittals and proposals o¥, 8~,~,~
the context that the Elwha dams will remain in place and not be removed in the near-
term future. The Department acknowledges that filtration technology of Purveyor's
GWI compliance strategy may not be appropriate if the Elwha dams are removed and
agrees that if such is the case the Department shall inform Purveyor of the Department's
position on this issue in writing upon final selection by Purveyor of the filtration
technology to be implemented.

States Environmental Protection Agency (USEPA) for regulatory violations associated
with GWI classification as long as the conditions of this agreement are being met.
6. Renegotiate Agreement {General}: The Department agrees to renegotiate the content
and schedule of this agreement if requested by Purveyor because of unforeseen
circumstances that occur that affect Purveyor's GWI-compliance activities.
7. Terminate and Renegotiate Agreement {Approval of Other Alternative}: The
Department acknowledges that Purveyor is evaluating compliance alternatives other
than filtration on a parallel schedule to this agreement. The Department agrees to
terminate this agreement and renegotiate a new bilateral compliance agreement, if
appropriate, if the Department approves a compliance alternative other than filtration.
8. Funding Delay: The Department acknowledges that Purveyor does not have adequate
funds to undertake detailed design and construction of filtration and related facilities.
DRAFT
The Department agrees to delay the schedule for completion of the Project Report and
all subsequent activities of this agreement by 1 calendar year for each year Purveyor is
unsuccessful in obtaining low-interest Public Works Trust Fund (PWTF) loan funding or
other grant funding to cover the costs associated with the detailed design phase and
construction phase of the project. The first opportunity for Purveyor to apply for a
PWTF loan is the spring of 2001. Purveyor shall apply for a PWTF loan at that time.
The Department shall review the loan application prepared by the Purveyor and
provide comments for revisions, additions, or improvements to the application to
maximize the potential for success in obtaining a PWTF loan. The Department shall also
provide assistance (by validating the importance of the GWI-compliance improvements
and the immediacy of their need) to Purveyor in its efforts to obtain state and/or federal
grant funding.
9. Elwha Dam Removal Impact: The Department acknowledges that the National Park
Services is currently planning supply and treatment facilities for Purveyor and other
Elwha river water users as mitigation for the proposed removal of the Elwha dams. The
Department acknowledges that mitigation treatment for Purveyor's domestic water
system is expected to include filtration technology with capabilities that meet or exceed
those of the filtration technology to be evaluated by Purveyor as part of this agreement.
The Department acknowledges that, at the time of this agreement, the schedule of
Purveyor's GWI compliance activities is similar to the Elwha dam removal schedule of
activities for planning and designing mitigation facilities for the City's domestic and
industrial water systems. Thus, Department agrees that at some time, depending on the
results of Purveyor's pursuit of filtration and non-filtration GWI-compliance
alternatives, it may be appropriate for Purveyor to discontinue its own pursuit of GWI
compliance in recognition of the parallel activities being undertaken on its behalf by the
National Park Service that may enable the City to become GWI-compliant. Therefore, if
appropriate as determined by the Department, the Department will agree to renegotiate
this agreement to more closely align the scope and schedule of activities with those of
the Elwha dam removal project.
It is understood that failure to comply with this agreement without reasons acceptable to
the Department may result in the termination of this agreement and the issuance of a
departmental order or referral to the USEPA for enforcement. Failure to comply with a
departmental order may result in the imposition of penalties of up to $5,000 per day, per
violation.
All documents or reports required by this agreement, questions about compliance, and
requests to modify this agreement shall be directed to:

Summary:. Staff will present a summary of power supply issues for the period 2002-2006.
.Recommendation: Information only.
Background / Analysis: Electric utility staff is preparing to meet our power supply needs for the
period from October 2001 through September 2006. A requirements service contract through the
Bonneville Power Administration appears to be our most cost effective resource for this period.
Bonneville has just completed their rate case for this period and has made several changes from our
prior contract. Staff will make a short presentation on the following contract provisions.
Process (rate case, subscription)
Contract term
Changes to power billing determinates
Conservation and Renewables Discount
Conservation Surcharge
CRAC (Cost Recovery and Adjustment Clause)
Environmentally Preferred Power
At the next UAC meeting, staff will present actual monthly rates and how it will affect the costs to
the Port Angeles system. Price comparisons will be made between our current rates and the rates
for the period 2001-2006.

UTILITY ADVISORY COMMITTEE MEMO
DATE: July 10, 2000
TO: UTILITY ADVISORY COMMITTEE
FROM: Scott McLain, Deputy Director of Power Systems
SUBJECT: Revenue Requirements Analysis for Solid Waste and Electric Utilitie~'~t~
Summary: Staff feels it is prudent to perform a financial analysis for the Solid Waste Utility and
the Electric Utility in 2000. Proposed costs have been received from Economic and Engineering
Services for a complete Cost of Service analysis in the amount of$11,600 for the Solid Waste Utility
and $27,950 for the Electric Utility. Staff expects that a full blown study will not be necessary and
estimates that the actual costs will be about $5,000 for the Solid Waste Utility and $12,000 for the
Electric Utility. The recommendation requests authorization for the full cost of the studies should
they be necessary.
Recommendation: UAC recommend to Council to enter into a contract with Economic and
Engineering Services to perform a financial analysis of the Solid Waste Utility not to exceed
$11,600 and the Electric Utility not to exceed $27,950.
Background / Analysis: Staff normally does a formal financial review of each utility every three
years. These reviews project costs and expenses for five years into the future to determine if the
rates that we charge our customers are adequate to cover the expected operation and maintenance
costs along with the projected capital spending for the utilities.
The Solid Waste Utility was last reviewed in 1997. It was not necessary to adjust rates for this utility
at the time of the study. At that time the Council directed staff to try to keep the current landfill cell
operational until it was filled, which was expected to be about the end of 2006. Several operational
changes have occurred and capital projects proposed since that study was completed. Staff feels it
would be prudent to re-evaluate the financial aspects of the landfill and project revenues and
expenses through the end of 2006. The Utility appears to be in good financial shape and staff
believes that a revenue requirements analysis will be adequate rather than a full blown cost-of-
service study. Sta£f requested a proposal for this study from Economic and Engineering Services
and has received an estimated cost of $5000 for a revenue requirements only study or $11,600 for
a full cost of service study. Money was not directly budgeted in the 2000 budget for this analysis
but staff feels that this project can be accomplished without increasing the overall Solid Waste
budget.
The Electric Utility was last reviewed in 1995 prior to the last Bonneville Power Administration
wholesale rate adjustment. Staffrecommended and Council approved lowering retail rates by about
12% at that time. Wholesale power rates from BPA will be changing again in October of 2001 along
with the end of contracts with our other sources of wholesale power in 2003. The electric utility is
in very good financial shape at this time, but with so many changes taking place in our wholesale
power supply, which accounts for about 68% of our expenses, staff feels we should project our
revenues and expenses through the next BPA rate period, (Oct 2001 - Sept. 2006). Because of our
good financial position, staff feels an updated revenue requirements analysis will be all that is
needed rather than a complete cost of service study. The EES proposal for the electric utility was
about $12,000 for a revenue requirements study and $27,950 for a full blown cost of service study.
The Electric utility budgeted $40,000 in 2000 to perform a cost of service study.
If staff feels that it will be necessary to perform the complete study for either utility, UAC and
Council will be notified prior to proceeding to this step.
The studies performed for both the Solid Waste Utility in 1997 and the Electric Utility in 1995 were
performed by in-house electric utility staff. This position has been eliminated from the utility and
we are requesting these services from an outside consultant.

Water Marketing in Washington: Negotiating for the Future
Water marketing is bocoming an increasingly important element in managing municipal water
supplies, instream flows, and other beneficial uses in 'Washington state. This year's AWRA
mmual conference will feature a keynote speaker from a western state actively involved in water
marketing successes and ehallanges. Confirmation of various speakers for the conference is in
progress. Experts from Washington and other western states will address policy, legal,
economic, environmental, and scientific aspects of water marketing. A range of diverse
perspectives will be featured, including Native American tribes, Washington water cOnservancy
boards, Depa~huent of Ecology, local governments, industry, and public interest. Case studies
will be presented on several water market transactions currently in progress in Washington
involving the Washington Water Trust, the Yakima Bureau of Reclamation, Eastern Washington
irrigators, and Western Washington municipal water suppliers. Other creative approaches to
water marketing being pursued in Washington state in both urban and non-urban environments
will also be presented.
Sign-up now and reserve your spot for this one day conference at the Seattle Art Museum. Look
for more information on featured speakers and topics in upcoming newsletters, flyers, and on the
