Utility Advisory Committee Memo June 10, 2008 Utility Advisory Committee Larry Dunbar, Deputy Director of Power Systems Energy Northwest Membership Presentation Summary: Energy Northwest is recruiting publicly owned electric utilities within Washington State to apply for membership. Energy Northwest representatives will present additional membership information at today's meeting. Recommendation: For information only, no action requested. Background/Analysis: On May 13,2008, staff shared information with the Utility Advisory Committee about Energy Northwest to gauge the City's interest in becoming a member. The Utility Advisory Committee directed staff to invite Energy Northwest to a future meeting to provide additional information about membership. N:\UAC\DepDir\Energy Northwest Membership Presentation.doc 1. We recommend that you to present the costs and benefits of membership from the City's perspective, Costs of Energy Northwest Membership: No monetary costs. We would expect you to appoint a Board of Director's representative that would come to our quarterly meetings and actively participate (EN pays for Board travel expenses). The Board of Directors provides feedback to EN staff and the Executive Board. It has to exclusive authority to start and stop projects. It elects five Board members to the Executive Board and three "outside" Executive Board members. Benefit of Energy Northwest Membership: EN members have first rights to all our new projects; As a Board member you get an opportunity to shape the future direction of EN. Quarterly you get to meet with and learn what is happening at EN and at our othertwenty two member utilities. You get access to all our services at costs. 2. the City's membership obligations, There is no legal or financial obligation to any EN project. The only obligation would be if you choose to become a participant in one of our future projects. We would hope as a member that you would find value and actively participate in quarterly Board of Directors meetings. 3. and a summary of recent Energy Northwest projects including various participation options and charges. Pacific Mountain Energy Center - EN attempted to permit a 700 MWe IGCC project in Kalama, Washington to serve as a base load thermal resource. The development costs were 100% assumed by EN. We had members considering everywhere from a few MWe to a hundred MWe. This project was stopped as we were unwilling to meet the permitting requirements of EFSEC. Nine Canyon Phase 3 - we just completed an additional 30 MWe of wind at this site bringing it to 95 MWe. In this case the current participants elected to take all of this additional resource. Other members would have been next in line. Reardan Wind - we started over three years ago to permit additional wind resources in Washington for our members. Without any federal incentives for public power, our costs would have been about $95/MWe at the bus (no transmission or firming). This could have been reduced about $15 to $20 per MWe with incentives but none were available. Since we were at the end of our land leases we sold our development interest. Radar Ridge Wind - we continue to work with national legislators to fix the CREB public power renewable incentive program. We have obtained land leases and began our wind and environmental assessment of this Pacific County wind site. Initial development costs to date have been paid by EN. At the direction of our Boards, going forward development costs will be shared by EN and project participants. We held our members only meeting for possible participation in this project on June 6th. If the CREB program is not revised in the next year, we would expect to develop this site as a private/PTC project similar to the White Creek Wind project recently developed. We will continue to prospect for additional wind sites. We have investigated both woody and dairy biomass; small hydro applications; are monitoring the development of PV/solar thermal/geothermal/wave and tidal/pumped storage/simple and combined cycle gas plants/long term nuclear strategy. Our O&M services have assisted members with peak manpower assistance, obtaining and installing small power supplies, operation and maintenance of member's generation assets. 4. You should also point out how Energy Northwest membership could satisfy some or all of the City's Tier 2 power needs beginning in October of 2011. Energy Northwest remains committed to its mission to aggregate the power supply needs of its members and provide cost effective solutions. We will continue to develop renewable projects for those who need or want them. We will continue to listen to our members and develop cost effective base load generation projects to meet members Tier 2 needs. This could be anywhere from a small simple cycle peaking unit needed for wind firming or capacity needs for a mid to large size CCCT if the aggregated interest is high enough. Tier 2 needs might be assisted by EN by aggregating the needs of many of our smaller to mid size members and negotiate a contract purchase with a private developer. EN is monitoring the power supply management options our members have. If we see that the options are either not available or don't meet our members needs, we will attempt to aggregate interest and help satisfy these needs. Bottom line is that Tier 2 needs and options are unclearat this time. EN will listen to our members and attempt to provide as many options as we can. 5. The City owns and operates a small hydro project (morse creek), you should let us know what services, if any, you could offer us in support of that project. EN prides itself in providing quality O&M services. We operate our own projects (CGS, Nine Canyon, Packwood (hydro), and White Bluffs (solar)). Up until recently we provided supervision and major maintenance support for the Klickitat Landfill Project HW Hill. We currently maintain the Mason 3 gas generator. We assisted Asotin PUD in developing a standby generator for its water supply. We have supported members and non membersin supplemental manpower for their hydro projects. 6. You should conclude with up to the top 3 reasons why the City should become a member now. Reason 1 - you recognize the value of EN as a regional JOA and you want to shape its future. . Reason 2 - you are facing uncertain future power supply needs and you want to aggregate your needs with others for more diverse and cost effective solutions to your needs. Reason 3 - the quarterly meetings and member forums will provide your utility an opportunity to interact with other public utilities. Date: To: From: Subject: ~ORiA.NGELES WAS H I N G TON, U. S. A. Utility Advisory Committee Memo June 10, 2008 Utility Advisory Committee Terry Dahlquist, Electrical Engineering Manager Canyonedge Cable Repairs, Project CL09-2007 Summary: Underground cable in several subdivisions is over 30 years old and has experienced failures in recent years. Most of the cable is directly buried and replacement would require trenching through pavement and landscaping. It is proposed to inject the cable at the Canyonedge Subdivision with a preservative that is guaranteed to prolong its expected life by at least 20 years. Recommendation: For information only, no action requested. On June 24, 2008, staff will request City Council approval to award and authorize the Mayor to sign a contract with Utilx Corporation for Project CL09-2007, in the amount of $25,424.00, including tax. Background/Analysis: Underground cable installed in the 1970's was projected to have a 30-year life expectancy. Much of the cable in the Canyonedge subdivision, located south of Ahlvers and east of Peabody Street, is approximately 35 years old, and has experienced a few failures. Typical of the 1970's, it is directly buried with no conduit. Replacement requires new trenching through pavement and landscaping. About half of the cable was replaced several years ago in conjunction with a telephone cable project that required trenching. That replacement cable was installed in conduit to facilitate future maintenance. The remaining cable could fail at any time and may cause an extended outage. Two companies in the United States offer an injection process for rejuvenating existing cables. An insulating fluid is injected at the cable ends. The fluid fills the cracks, which develop in old insulation. Both companies warranty the injected cables to last an additional 20 years. Both companies were contacted for bids. Their bids are based on the unit cost per foot of cable treated, plus the unit cost of each splice and injection fitting. Based on the estimated quantities required at this location, the cost of either bid, including sales tax, are nearly identical. Contractor Bid Amount Utilx CorporatIon $25,424.00 Novinium Rejuvlnation $26,615.00 N:\UAC\Final\Canyonedge Cable Repairs.doc Canyonedge Cable Repairs June 10, 2008 Page 2 Both companies test the cables prior to treatment to verify that the injection process will work. If they deterrriine the cable is too far deteriorated so they cannot warranty the result, they do not proceed with injection and the City will need to pay up to $5,000 for their mobilization and testing effort. If the injection is successful, the City's cost is about half the estimated replacement cost, and replacement is deferred at least 20 years. Cable cannot be injected a second time, but the warranty refunds the treatment fee if the cable fails during the wartanty period. Although this is a new approach for Port Angeles, Clallam County PUD and other utilities in the area have used the injection process successfully. Novinium Rejuvination is a relatively new corporation, only in existence for 5 years, and was founded by developers of the Utilx Corporation system. Uti Ix Corporation has been using their process for 23 years and has a proven ability to meet their warranty. Because of their proven performance and slightly lower bid, staff will be recommending to the City Council that they award the contract to Utilx Corporation. The City has not used this approach before and staff felt that it is important that we introduce it to the Utility Advisory Committee before bringing a recommendation to the City Council. This year's Electric Utility budget included $50,000 for cable replacement at the Canyonedge subdivision. Date: To: From: Subject: ~ORTANGELES WAS H I N G TON, U. S. A. Utility Advisory Committee Memo June 10, 2008 Utility Advisory Committee Kathryn Neal, Engineering Manager Industrial Wastewater Pretreatment Program Update Summary: The Wastewater Utility is required by the Washington State Department of Ecology to update its industrial pretreatment program to comply with our Industrial National Pollutant Discharge Elimination System permit, and to comply with Environmental Protection Agency standards. In addition to revising the Port Angeles municipal code, the updated program will specifically address the management of septic waste and the accumulation of grease in the sanitary sewer system. Recommendation: Forward a favorable recommendation to City Council to approve and authorize the Mayor to sign an agreement with G4 Consulting, Incorporated for technical services in an amount not to exceed $55,900. Background/Analysis: The Washington State Department of Ecology (DOE) performed an inspection of the wastewater treatment plant (WWTP) in 2007 that resulted in several recommendations and requirements, including the need to update the City's industrial wastewater pretreatment program. The City's current industrial wastewater pretreatment ordinance (PAMC 13.06) has not been revised since 1983. The primary tasks under the proposed agreement include the following: Task 1 Task 2 Task 3 Task 4 Task 5 Calculations to determine the maximum allowable loading to the WWTP which will be used to determine local limits for industrial dischargers. Evaluate the potential staffing required to develop and maintain the pretreatment program tasks and FOG program. Prepare revisions to the City's industrial wastewater pretreatment ordinance, based on the Washington State Model Pretreatment Ordinance. Prepare an update to the City's pretreatment program including procedures and required forms. The updated program will include guidance for minimizing grease accumulation in the sanitary sewer system, and for the management of septic waste that is being hauled directly to the WWTP. Develop a fats, oils, and grease (FOG) program. N:\UAC\Final\lndustrial Wastewater Pretreatment Program Update. doc Industrial Wastewater Pretreatment Program Update June 10, 2008 Page 2 The City has a major collection system problem with FOG, which creates blockages that may cause property damage, clean water act violations, National Pollutant Discharge Elimination System (NPDES) permit violations, and public health and safety concerns for the community. As part of the scope of work, the consultant will work with staff and wastewater customers to draft an updated program, with options, for future consideration by the Utility Advisory Committee and the City Council. The level of effort related to this task is focused on meeting with the City and related businesses to develop an approach for future implementation. The updated program will include a manual of procedures for staff to follow in maintaining compliance with all federal and state requirements, and implementing the City ordinance. It will also include the appropriate forms to be used during program implementation, if the City chooses to pursue that option. The program will also include an update to the enforcement response plan (ERP) that will be acceptable to the city as well as the DOE. A functional ERP is critical to the successful implementation of the pretreatment program as well as the management of FOG in the collection system. At this time the City is only partially authorized by the state of Washington to manage its own industrial pretreatment program. The analysis included in this scope of work will be used in part to assist in a later City Council decision on whether to become fully authorized. The city reimburses Washington state approximately $10,000 per year for managing the significant industrial users (Sills) within the city. The City is responsible to manage the permitting and enforcement for minor industrial users (MIUs). The scope of work is summarized in the table below, which includes the budget for all tasks under the agreement including travel expenses. Estimated Task Hours Cost , , 71 $11,000 Task 1 Local Limits Task 2 Staffing Summary 36 6,000 Task 3 Sewer Use Ordinance 40 7,000 Task 4 Procedures Manuals 120 20,000 Task 5 FOG Program 80 12,000 Total Costs 397 $56,000 Adequate funding for this effort is available from current Wastewater Utility operating and capital improvement program budgets. G4 Consulting, Incorporated from ForestGrove, Oregon is the recommended technical consultant because of their track record updating similar programs in the northwest, and excellent recommendations received. The principal ,of G4 Consulting, Mr. John Greeley, is well respe<:;ted within the specialized area of industrial pretreatment. His statement of qualifications, summary of projects, and references are available on request, or from the City's website. It is recommended that the Utility Advisory Cominittee forward a favorable recommendation to City Council to approve and authorize the Mayor to sign an agreement with G4 Consulting, Incorporated' for technical services in an amount no no exceed $55,900.

Utility Advisory Committee Memo June 10, 2008 Utility Advisory Committee Ernie Klimek, W aterlW astewater Collection Superintendent Leak Detection Program Annual Report Summary: The City has utilized leak detection companies for the past eighteen years to detect water leaks in the distribution system. Detecting and repairing leaks results in the utility becoming more efficient in the areas of water conservation and is part of the City's Water Use Efficiency Program goals. This year's leak detection survey was performed from March 1 ih through March 21 st. The estimated combined water loss that was detected was found to be 3,600 gallons per day. Recommendation: For informational only, no action requested. Background/Analysis: Each year the WaterlWastewater Collection Division contracts with a leak detection company to perform a survey of one- fifth of the water distribution system. The Utilities Services Group ofHD Supply Waterworks conducted the survey this year. Extremely sensitive sound amplification instruments and computer-based correlations are used for pinpointing leak locations. The main area covered this year was from Cedar to Lincoln Streets (West - East) and 2nd Street to Lauridsen Boulevard (North - South). Also included was the area from Lincoln to Chambers (West - East) and 6th to Lauridsen (North - South). This year a total of approximately 33 miles of piping was surveyed including all intersecting lines. Approximately 40 hours were spent on this project by the leak detection company and a total of 5 leaks were found within our distribution system. The water loss due to leakage was estimated to be approximately 3,600 gallons per day (GPD), which would equal!.3 million gallons per year. Three of the leaks have already been repaired, with two remaining leaks to be repaired. In addition, the Water/Wastewater Collections Division took this opportunity to do test demonstrations on some new leak detection equipment that it can use in-house to further expand the leak detection program. The tests produced comparative results from those found from the leak detection services company.

Utility Advisory Committee Memo Date: June 10, 2008 To: Utility Advisory Committee From: Ernie Klimek, W ater/W astewater Collection Superintendent Subject: Water Use Efficiency Program Annual Report Summary: The City is required to annually report our progress toward reaching Water Use Efficiency program goals to our customers and the Washington State Department of Health. The report was provided to the Department of Health and the information was shared with our customers in our 2nd quarter compliance mailing. Recommendation: For information only, no action requested. Background/Analysis: In accordance with the Water Use Efficiency (WUE) program an annual report was submitted to the Washington State Department of Health. The 2nd quarter compliance mailing to our customers included our current activities under the WUE program as follows: LEAKAGE INFORMA nON The annual distribution system leakage calculation for the 12-month reporting period from January 2007 through December 2007 is provided below. Total production from the Elwha source in millions of gallons: 1,141 Total authorized consumption in millions of gallons: 900 Unaccounted for distribution system water in millions of gallons: 242 Distribution system losses as a percentage: 21% N:\UAC\Final\Water Use Efficiency Program Annual Report.doc Water Use Efficiency Program Annual Report June 10, 2008 Page 2 GOAL SETTING INFORMA nON After public input, the following WUE program goals were set by City Council on December 12, 2007. The goals are: SUPPL V-SIDE GOAL: The Water Utility will implement a program intended to achieve a one percent reduction in distribution system leakage per year and improve the accuracy and accountability of the system through meter replacement and calibration. DEMAND-SIDE GOAL: The Water Utility will implement a program intended to achieve a two-tenths of one percent reduction in customer consumption per capita per year including offering a minimum of six water use efficiency measures to all customers. Since this is the first annual report, which establishes the future baseline, there are no measured results toward reaching the above goals. However, the Public Works and Utilities Department reported that it is performing leak detection, repairing leaks, and doing meter change outs at this time. . We have also offered water conservation kits with currently over 2,000 customer participants.
