LIQUID LUBRICANTS _ 6-197 SAE Viscosity Number crankcase oils constitute a classification in terms of viscosity only, They are given in Table 1 . Some oils with flat viscosity-temperature curves lie within the limits of two SAE grades; these are called multigrade o' For example, an oil with a viscosity of 15 centistokes at 210' (99°C) and 1,300 centistokes at 0°F (—18°C) would be a 10W- 40 grade. Selected base oils or the addition of viscosity-index (VI) improvers can be effective in blending these multigrade lubricants. The selection of a winter crankcase oil should be based upon the lowest anticipated atmospheric temperature, whereas a summer crankcase oil should be based on the highest tempera- ture expected. It is generally recommended that the followii temperatures be used in selecting the atmospheric-tempera- ture limits for the various SAE viscosity numbers: —10, 0, 10, 32, and 90' 23, —18, —12, 0, and 32°C). The SAE viscosity numbers for gear and transmission lubricants constitute a classifi They are given in Table 2. The classification is based on the lubricant viscosity mea- sured at both high and low temperatures. The high-tempera- ture viscosities are determined according to ASTM D455 Method. The low ~temperature iscosities are determined according to ASTM D2983-71T Method using the Brookfield viscometer.

LARSEN BAY HYDROELECTRIC PLANT VOLTAGE REGULATOR REPLACEMENT Oct. 24, 1996 Subject: Larsen Bay Trip to replace Voltage Regulator Stan Sieczkowski The trip to Larsen Bay was successful. The hydro was put on line and operations reviewed by the town council. Arrived at Larsen Bay at 1:30 PM on 10/23. Joe and | went to hydro after talking with Mayor Christiansen. There was water over the spillway. We checked out the level probe and decided it was okay. We read 20vdc (open circuit) at the dam. The transducer read 1.54 ohms open circuited. Same as new transducer. Reconnected the transducer and read 1.44v (this is a 4-20ma loop therefore the reading does not mean much. We could not insert a ma meter into the circuit so assumed it was reading OK. Went to plant. Joe changed out the voltage regulator while | checked out the level meter. The pot and shunt resister is a T&H add on to enable a O-1ma meter to operate in the 4-20 circuit. The meter appears to be shot. Also the switch added to disable the level transducer was mismarked. I.e. O mean in and a slashed o means out). | decided to run hydro without meter indication. Joe started unit in manual control. Unit tripped by reverse current relay. Checked out and found with level out of circuit the controller gets no feedback and will trip unit since it assumes it has no output. Switched probe in circuit and the hydro ran fine. ADJUSTED THE VOLTAGE TO 480 VAC. and synched hydro to line. Then the diesel was shut down. The starter is gone on one of the diesels. Left plant at 6:00 PM. Attended Council meeting at 7:00 PM. Long meeting lasting until 12:30 AM. Operation of plant and Office help was my main focus. The council agreed to provide a last chance letter to Marie and advertise for a position to help Flora. An Executive session was held for the hydro operator. Council was advised to develop criteria for their operators and adhere to them. Also two new people are to be selected and trained to operate generating plants. he Recommended to Harold to: Clean up the plant. Store the spare transducer. A new level meter was ordered and needs to replace the one in panel. Check daily and even twice a day the water level until the meter is replaced. Clean up the battery terminals at hydro. (the diesel batteries need also) Provide the monthly meter readings by the 5" day of month. Use the meter reading form provided by Flora. NOORWNS Thomson and Howe Energy Systems, Inc.

I've spent some time with Richard reviewing his inspection of the turbine runner cracks, and offer the following observations and possible causes. The Larsen Bay turbine has been in operation since early 1991. Normal turbine loads are a small percentage of the unit's capacity, except during periods of the year when the cannery is in operation. During cannery operation, the turbine occasionally operates near maximum capacity. Our records indicate Alaska Power Systems replaced the drive side bearing and drive coupling element in July, 1994. This bearing failure was such that the inner race of the bearing was fused to the turbine shaft, causing shaft damage. The shaft was repaired by Alaska Power Systems. We have not had specific reports, but understand the system has seen occasions when the pond has been drained down too low. The penstock has apparently required some maintenance due to cracks and joint separations. As you know, Pelton turbines, by design and operation, tend to be highly resistance to damage from debris or foreign objects. We've had customers, for various reasons, run rocks and gravel through their turbine with little or now apparent damage to the runner. Richard did not observe damage to the buckets consistent with damage normally caused by debris in the penstock. A faulty casting may develop cracks in or around the buckets. The cracks repaired by Richard may be the result of weak casting areas. However, casting or design flaws typically become obvious within the first 3 - 6 months of operation. We would expect any such defects to be noticed during routine inspections, and certainty during the time the runner was removed for work on the shaft. The bearing failure in 1994 was total, and was apparently accompanied by a failure of both the temperature RTD, vibration switch, or control panel. We can assume the runner was subjected to significant vibration, which may have started the cracks observed by Richard. (860) 592-5552 e FAX (360) 592-2235 Page 2 S. Sieczkowski Air entrapment in a penstock will compress as the air is carried downhill and the air is subjected to higher penstock pressure. When the highly compressed air passes through the needle nozzle, it is no longer contained and rapidly expands. With a head of 650 feet (280 PSI), a better description is that the air "explodes" when exiting the nozzle. This sudden expansion in the turbine jet significantly impacts the runner bucket in two ways. Firstly, the jet segment ahead of the air is pushed into the bucket with greater than normal jet force. Secondly, and more damaging, the jet upstream of the expanding air is broken and delayed. This jet delay interrupts the normally smooth transfer of power from the jet to the runner buckets, and results in a significant and likely damaging impact of jet against bucket. Of the possibilities we've reviewed, air is the most likely cause of damage to the Larsen Bay runner. Air can enter the penstock at the point of intake, even if the intake is submerged. It must be allowed to exit the penstock through several stand pipes or air release valves. Air release valves should be fitted with “anti siphon" checks, so that air cannot be drawn into the penstock through the air release valve. A second possibility for air intrusions is through a break or crack in the pipeline, particularly if the break is near the upper end of the pipeline. We'll want to keep a close eye on the runner, as a weld repair may not completely correct the problem. A review of the present pipeline air release system may insure the runner is not further damaged. | hope this is helpful to you in the long term operation of the plant, but | look forward to discussing any questions or comments you have. a, in Daniel A.

ULL. Listing Undervoltage release devices are listed by Underwriters’ Laboratories, Inc. as field mountable accessories under File E64983. Installing a UVR on a Systems Pow-R Breaker will not void the breaker U.L. listing. 2. General Information An undervoltage release (UVR) device is an accessory used in a circuit breaker which trips the breaker when the voltage, usually line voltage, drops below a predetermined level. This level is between 35% and 70% of rated voltage for the UVR devices discussed in these instructions. A minimum of 85% rated voltage is required for the breaker to close. The UVR consists of a circuit board which monitors the line voltage, and a solenoid which trips the breaker when the voltage drops sufficiently. The UVR is reset automatically by a reset arm when the breaker opens. The UVR is furnished in kit form for field mounting and includes all necessary installation details, including hardware, suppiementary labels and wiring. All components are for mounting internally in the center pole as described in these instructions. A typical UVR accessory kit is shown in Fig. 1. Voltage and current ratings are given in Table 1. Fig. 1 Typical UVR accessory kit LL. 15162-A Voltage Current in Amperes 24 Vde .09 32 Vde .09 48 Vde .09 60 Vde .02 125 Vde 02 24 Vac 09 48 Vac .09 _ 120 Vac 02 208 Vac .02 240 Vac 02 480 Vac 02 600 Vac 02 Table 1 Voltage and current ratings for UVR devices CAUTION BEFORE ATTEMPTING TO INSTALL ANY CIRCUIT BREAKER ACCESSORY, THE CIRCUIT BREAKER MUST BE OPENED AND THE STORED ENERGY IN THE MECHANISM SPRINGS DISCHARGED. THE BREAKER SHOULD BE REMOVED FROM THE CELL AND TAKEN TO A SUITABLE WORKBENCH WHERE THE INSTALLATION CAN BE PROPERLY MADE AND TESTED BEFORE BEING PLACED IN SERVICE. GENERAL INSTRUCTIONS FOR OPERATING SYSTEMS POW-R BREAKERS ARE PROVIDED IN I.L. 29-801 WARNING THERE IS A HAZARD OF ELECTRICAL SHOCK OR BURN WHENEVER WORKING IN OR AROUND ELECTRICAL EQUIPMENT. ALWAYS TURN OFF POWER SUPPLYING THIS EQUIPMENT BEFORE WORKING INSIDE SWITCHBOARDS. 3. Installation Instructions Read through complete instructions before attempting installation and apply a thread locking compound to all screw threads at assembly. 3-1. Remove charging handle and breaker front cover as per instructions in I.L. 29-801. Effective December, 1992, Supersedes |.L. 15162 dated November, 1987 @: 3-2. Mount UVR solenoid to the bottom of the accessory plate on the mechanism, as shown in Fig. 2, using a .138-32X1.50 flat head screw at the front and a .138-32X1.50 pan head screw with lock washer at the rear. Note: Apply 46-50 in.-oz. of torque to screws to ensure proper operation of the solenoid. Over tightening will distort the solenoid bracket. 3-3. Mount the circuit board to the bottom bracket of the mechanism with two .138-32X.375 pan head screws and lock washers, placing @ spacer on each screw between the bracket and the circuit board (see Fig. 3). 3-4. Route control wires from the center pole of the breaker to the right pole by feeding them under the mechanism side frame and along the bottom barrier. Then route the wires up the edge of the deck plate to the secondary disconnect plugs. Secure wires with wire ties so that they do not interfere with any moving parts in the breaker. See Fig. 3 for control wire routing. 3-5. Refer to Figures 5 and 6 for secondary plug or terminal block wiring details. Pan head screw Flat head screw Fig. 2 Installing the UVR solenoid Control Wire Routing Fig. 3 Complete installation showing solenoid, circuit board and control wire routing 4. Adjustment and Testing CAUTION OBSERVE NORMAL SAFETY PRECAUTIONS TO AVOID CONTACT WITK MOVING PARTS IN THE MECHANISM AS WELL AS ENERGIZED CONNECTIONS IN THE CONTROL CIRCUIT. 4-1. For breakers manufactured prior to February 1993, verify that the reset arm on the mechanism is pushing equally on the UVR and Flux Transfer Shunt Trip (FTST), if equipped. The reset arm can be bent to adjust. This style of reset arm has a single spring at the top. If the UVR solenoid is not resetting, bend the reset arm by driving the vertical portion to the right. Verify proper operation of the FTST using the "Test" feature of the trip unit. If the FTST is not resetting bend the reset arm by driving the vertical portion to the left No adjustment is necessary on breakers manufactured after January 1993. These breakers are equipped with an independent action reset arm which adjusts automatically. The independent action reset arm has two springs at the top. © 4-2. Test the UVR by energizing A11 and A12 and closing the breaker. The breaker should close. De-energize the UVR and the breaker should open. 4-3. Energize the UVR again and close the breaker to verify that the UVR has been reset properly. Note: If an attempt is made to close the breaker with the UVR de-energized, the breaker main contacts will momentarily (less than one cycle) make contact. 5. Return to Service 5-1. After proper mechanical and electrical operation is confirmed, replace the front cover and charging handle. Attach the UVR nameplate, supplied with the kit, to the side of the breaker cover adjacent to the UVR control wires. 5-2. Retum to service as required. Note: Westinghouse Electric Corporation assumes no responsibility for damage done to circuit breakers during field mounting of any accessory.

FIELD INSPECTION | arrived at Larsen Bay on the morning of April 19, 1995. Joe Katelnikoff, the project operator, accompanied me to the location of the leak. The nominal 18” diameter PVC penstock had been leaking at one of the slip joints located approximately 129 feet upstream from the first air release valve. By the time | arrived the operator and his crew had stopped the leak by stuffing rags into the bell of the joint and backing it with a rubber gasket and clamps. When | arrived, penstock was full of water and the hydro plant was off line but the community was drawing the domestic water off the penstock. There was noticeable deflection between the pipe sections. The joint deflection resulted from the downstream pipe section being deflected down and toward the canyon. Using wood blocking and a straight edge, | measured the deflection at 5/16” in 8”. This computes to a deflection of 2.25 degrees. The project drawing say the maximum deflection for the PVC slip joint pipe shall be 1 degree per joint. The leaking joint was in the road under 3 feet of cover. The leak was found when the project operator noticed water seeping out of the road bed. Using the known stationing of the air release valve, | calculated the leak to be at station 13+36. The center line elevation at that station calculates to elev. 1640.03’. The normal reservoir elevation is 1665.75’. The static head at the leak is 25.72’ or about 11 psi. The mayor of Larsen Bay felt the joint deflection was possibly caused by frost action. Although the pipe is bedded in frost susceptible soils, | did see and evidence of frozen ground in the excavation. The project operator confirmed they did not encounter any frozen soil when they were excavating for the leak. In my opinion the deflection in the joint was caused by the ground downstream of the joint moving down slope toward the creek. The movement is evidently small; | searched for but did not find any ground cracks in the vicinity. Since temporary repairs had been made and the penstock was serviceable, | decided to return to Anchorage and perform further analysis before making recommendations for permanent repairs. | noted the following spare penstock material. PVC stored on ground behind water treatment plant: 3 full length (21’) sections plus one 63” section. Pipe has been exposed to the sun for some time and is not UV treated. (At the time | had some reservations about its suitability for use.) Steel pipe stored with PVC pipe: 3 sections of spiral weld steel pipe Mechanical couplings stored in the project storage building: Two ROMAC 501 16 with 18.45-18.97 yel gaskets. One ROMAC 501 16x14 w/ gaskets The project operator put the hydro plant back on line at 4:40 p.m. on April 19, 1995 and | departed Larsen Bay on the 6:00 p.m. flight. RESEARCH AND ANALYSIS | considered 4 options for the repair of the penstock; 1. Leave as is with rags stuffed in joint. | ruled out this option because the rags will rot and the joint will start leaking again. 2. Replace rags with a permanent material such as oakum. | also ruled out this option because | could not be sure the backing gasket and clamps would last. 3. Repair the joint with a bell joint clamp. 4. Cut out the joint and replace with a short section of pipe and the two ROMAC 501 16 mechanical couplings. | searched the microfilm records at the AIDEA office and was able to locate the original invoice for the PVC pipe. From the invoice, | determined the supplier was Pacific Water Works in Seattle. | contacted Mark at Pacific Water Works, 800-426-9860. Mark said the PVC pipe most likely manufactured by JM Manufacturing. 4044 | contacted JM Manufacturing, 800-621-222, and spoke with a Mr. Boits at extension 2118. | explained the Larsen Bay situation to Mr. Boitz and obtained the following information: e Maximum recommended joint deflection for is 1.5°; more than that will cause leaking, however, 2.25° is probably not enough to overstress and crack pipe. e Can repair with a bell joint clamp. However, for that size pipe, joint clamp will have to be custom made; Smith-Blair of Romac could make one. (Use bell joint clamp only if ground has stabilized.) e If penstock can be taken out of service, recommend cutting out joint and replacing with a short section of pipe and mechanical couplings. e As to condition of pipe which has been exposed to sun since 1988, Mr. Boitz says sun bleaching is only superficial and pipe should still retain original strength. | then contacted Eric Marchigiani, 907-269-4684, and confirmed that the ROMAC 501 16 mechanical couplings were intended for use on the 18” PVC pipe. Based on the above information, | determined the best repair procedure would be to cut out the joint and replace with a short section of pipe and the two ROMAC 501 16 couplings. | contacted Stan Sieczkowski and informed him of my recommendation. Mr. Sieczkowski concurred and authorized me to oversee the repair and to contact the Mayor of Larsen Bay to make the arrangements. oe Phe be as re L, tet 9 Por ee 50 neslele | 6. © Laesern Cay Tydeo_ Bac i deo Encl Dicken oto cK cae me eo o) oO —_ ee Soh <+{-— pam Boad To E Oi- 0\0 Yiu ip 2D m |e Ef AIR RELIEF ows) E> Nee K,.

The run of river Hydroelectric plant went on line in July 1991 and is the primary source of electrical power and the diesels are used as hot standby units. The Hydro supplies the City electrical power an average of 10 months a year while there is plenty of water in the stream. The project operation is automatic, however it requires a daily site visit by the local operator to take electrical readings and check the lube oil levels and water supply. The City Town Council oversees the operation, maintenance, and administration of the City Utilities. The Mayor serves as the daily administrator for the city. There are approximately 150 residents and about 61 residential electrical meters.. EXECUTIVE SUMMARY The City of Larsen Bay and State of Alaska researched, financed, and constructed the Hydro Project. Grants, Loans, and Bonds were used to fund the project. Agreements between State, the City and local Cannery are in place to provide for the 20 year debt service Bond financing and the operation and maintenance costs. The annual project budget is developed by AEA and submitted to the council for action. The Project revenues are planned to provide for all the Project payments. The revenues have been less than expected and the accounts receivable and energy losses have been higher than normal thus leading to a shortfall of funds to pay all debts. The order of payment is Bonds first, Project O&M second, then the DCRA Power Project Fund (PPF) Loan. However to date, the PPF loan has never received a payment. The City monthly payments have been inconsistent since July 1994 for Bonds and O&M, and the City is approximately two years in arrears for the PPF Loan. The City manages, administers, operates and maintains the project with support from AEA for the Hydro Project. DCRA supports the City with the Circuit Rider Program for the Diesel Plant and Bulk Fuel Storage facility. The current power sales rate is set at $.40 / KWH to cover the Utility costs and the City is eligible for PCE support at $.0828 / KWH. The cannery rate is $.095 / KWH plus a monthly installation charge. The Hydro Project is currently on line and carrying the City load. The Hydro Project has had three major failures since construction. Repairs were made using Reserve Funds or Insurance proceeds. There have been several ideas and numerous meetings to resolve the utility cash flow, increase project revenues, and provide for the routine reports to receive PCE. There is still problems with late filings, inaccurate reports, and high accounts receivable. CONCLUSION Me Lo The current monthly KWH sales are inadequate to fund the DCRA PPF Loan payments of approximately $45,500 per year. A substantial rate increase from $.40 to $.54 per KWH is required to assure payment. The Project operation and maintenance expenses and the Renewal and Replacement contribution is as low as possible to adequately maintain the project. There is no practical way to increase the KWH monthly sales in the community in the near future. A contract Administrator for the City would have some benefits because: The debt service payments could be assured. The accounts receivable could be improved. The cash flow and daily operation could be monitored better. The Administrator would also increase the cost but not necessarily improve the net increase of funds. ao oP A proposal to get legislative support or aid by a grant, loan forgiveness or loan refinancing should be introduced by the City. The power sales rate should be adjusted and PCE reports filed properly to offset the high cost of electrical service. J HYDRO PROJECT HISTORY GEOGRAPHIC LOCATION Larsen Bay is located on the island of Kodiak in Uyak Bay, approximately 60 air miles from the City of Kodiak and 250 air miles from Anchorage. The community has approximately 150 permanent residents with a large seasonal influx of cannery workers and fishing fleet crews. It is normally accessible by air or boat only during favorable weather. HYDRO PROJECT DESCRIPTION The hydro project consists of a 6,062 foot penstock made up of steel and PVC pipe. The dam is 140 foot wide earth filled and is 14 feet in height. The run of river 475 KW pelton turbine/generator is located in the wood structure powerhouse close to the City domestic water tank. The project head is 670 feet. Power is delivered to the city's existing electrical distribution system. The Kodiak Salmon Packer’s Inc. cannery is connected to the electrical distribution system as part of the City power load. The City has connected a 4 inch domestic water line from the Hydro penstock in the powerhouse to the City water tank for a fresh water supply source. HYDRO PROJECT BACKGROUND The project is a culmination of several studies provided by consultants for the City of Larsen Bay and the Alaska Energy Authority. Grants, Loans, and Bonds provided the project financing. Design and construction of the Hydro project was performed by the City employees, contract construction workers, and consultants. Management oversight was provided by the City and Alaska Energy Authority. A Loan Agreement (Aug. 25, 1987), Cooperative Agreement (May 1, 1991), Indenture of Trust Revenue Bonds (May 1, 1991), Grant Agreement (May 11, 1991), and a draft Operation and Maintenance Agreement (Oct. 1992) exists between the City and the Alaska Energy Authority. A Power Sales Agreement (May 1, 1991), exists between the Kodiak Salmon Packers, Inc. and the City of Larsen Bay. The project went on-line July 5, 1991 and was dedicated on August 9, 1991. Project completion occurred on October 31, 1991 with the connection of the cannery. The cannery has six diesels (combined capacity about 1 MW) and will run their diesels when the cannery is in full production. This occurs during June, July, and August to supplement the Hydro operation. FUNDING Funding for the project was provided by: PROJECT CONSTRUCTION AMOUNT State Grant Funding $639,000 PHS Grant Funding $125,000 State PPF Loan (DCRA) $493,694 Bond Financing (AEA) $855,000 Total Funds $2,116,694 The financial support for the project was based upon an estimated 520,000 KWH energy sales per year at the residential energy rate of $.40 / KWH and commercial rate to the cannery of $.095 / KWH. The order of payment for the project is 1- Bonds 2- O&M 3- Loans. The annual budget is developed so the project will make annual Bond payments over 20 years and meet O&M expenses. The PPF Loan was agreed to a term of thirty years at 7.65%. The City can assume ownership of the project per the Cooperative Agreement (Sec. 4.10) when all obligations are satisfied. The Power Project Fund (PPF) Loan is assigned to the DCRA to administer. The Bonds, Operation and Maintenance is assigned to Alaska Energy Authority to administer. The DCRA PPF loan is delinquent at this time as no payments have ever been made. The AEA did authorize deferring payment until Jan. 1992. The Bond payments are current and the O&M cost are being paid from project revenues on a monthly basis. Several discussions have been held between the DCRA and the City to resolve the delinquent PPF loan payment. Suggestions have been made to: Request loan forgiveness from the legislature. Increase the energy rate to cover the payment. Restructure the loan to enable payments. wn To date nothing has been agreed to, although discussions continue. ADMINISTRATION The City has a Town Council and a Mayor. The current Town Council members are: Frank Carlson, Mayor Charles Cristensen, Vice Mayor Brad Aga, Member Mike Carlson, Member Jim Johnson, Member Lars Naumoff, Member Eli Squartsoff, Member The Mayor oversees the daily administrative duties of the City that are performed by two clerks, a hydro operator, a maintenance man and various laborers. There is no back up for these people and this is often a problem to maintain continuity. This has been discussed and back up has been attempted, but it has not been sustained. The City residents are mainly fisherman and it is very difficult to find qualified help for the Utility during the fishing season. The staff deal with meter readings that are inaccurate, or late, or not being reported in a timely manner which affects the billing and PCE reports. The accounts receivable is quite high. There are several accounts that need resolution as the PCE rate will be effected if a plan is not implemented to collect the back charges. All this adds up to a shortfall of cash in the utility account and the City getting behind in the monthly hydro project payments. The revenues and expenses are listed below: REVENUES FY 1995 ESTIMATE Sales $160,000 (based upon 400,000 KWH annual sales Interest $3,205 Cannery Monthly Minimum $11,725 TOTAL REVENUE $174,930 EXPENSES AEA Bond Debt Service $96,000 (Annual payment estimate) Project Operations & Maintenance $67,000 (FY 1995 Budget) DCRA PPF Loans $0 (Annual payment due is about $45,500) Project R & R Fund $5,000 (FY 1995 Budget) Subtotal $168,000 $6,930 (Contingency) TOTAL EXPENSES $174,930 The current City energy rate is $.40 / KWH. This is barely covering the generation expenses and does not cover the system distribution costs. The rate would have to be increased to an estimated $.54 / KWH at the present projected load of 400,000 KWH to cover the utility O&M costs and losses. The City PCE rate was reduced effective October 14 from $.2004 / KWH to $.0828 / KWH. This is because of the high energy losses, the fuel cost adjustment, and inadequate records or PCE filings. The City has an opportunity to have this reviewed but must have a new filing done and submitted by March 31, 1995 to cover a new test period. The effect of this PCE change may reduce energy sales if residents drop off the City electrical system due to the increased costs. AEA and DCRA representatives met with the Mayor and several council members to discuss these issues on Oct. 26 and 27, 1994 OPERATION The City of Larsen Bay has one employee who performs the operation of the projects. The operation appears to be satisfactory as the operator responds to outages and coordinates the major load change with the cannery during the fishing season. The operator makes daily checks on the hydro and starts the diesels once a month. He takes the monthly meter readings and prepares the monthly electrical bills. He has worked on the project since it went on line in 1991. He also maintains the City distribution system. This is a full time City job and his time is split 40% Hydro and 60% City. The operator does not fish but is unavailable when out of the village or for personal reasons. The City has attempted to provide a backup operator in the past and is trying again. The Hydro provides the energy as the primary source until there is no water in the stream or there is a major equipment failure. It appears the City loads are 25% less than estimated when the project was constructed. The average yearly sales has been about 400,000 KWH vs 520,000 KWH expected. The Council has looked at additional load growth but there is only a limited potential. The boat harbor would be a significant load if approval and funding were available. The airport lighting system has added some load this year but the cannery production has been less than expected. A remote possibility to reduce fossil fuel use is to convert the local school that uses fuel oil for heating and hot water. The school may be interested in converting to electricity at avoided cost if funding for the conversion were available. This idea would need more research to verify the compensation. The Hydro plant has plenty of capacity for the current City demand and will allow for future load growth. Presently the Hydro is operating at approximately 35% capacity in the winter and full capacity when the cannery is in full production. The cannery operates its diesels to make up the difference in generation needed at the cannery during this time. The City has first rights to the Hydro energy over the cannery. The City electrical system has a history of unusually high energy losses due to a combination of suspected inoperative meters, bad connections, or inadequate records. They have recorded energy losses from 10% to 38%. The City PCE rate has been affected by these high losses. It has been recommended to have the high energy loss problem solved. MAINTENANCE The routine maintenance is provided by the local operator in accordance with the Operations and Maintenance Plan and the Manufacturer’s Equipment Manuals. Bi-annual Inspections of the facilities are made by the State and annual insurance inspections are made by the Insurance Company representative. The facilities are being maintained in accordance with the recommendations. There have been three major failures to the project since going on line in July 1991. They were: 1 PENSTOCK FAILURE (Feb. 1992) The penstock failed at the transition joint. The reducer slipped down the plastic pipe onto the steel pipe. It was suspected that the transition joint was not properly installed which allowed the slippage. There was a major road wash out because of this break. An AEA engineer and the local operator dug out the pipe at the break and repaired the penstock joint. The project was down for 14 days and the power was supplied by the City diesels. 2. VIBRATION, FOUNDATION, OUTER TURBINE BEARING (Feb. 1994) The generator set developed a vibration and cracks in the foundation appeared. A planned shutdown to repair the vibration and replace the outer bearing was done in February 1994. The outage was originally planned to coincide with low water period (during March to May) when the City diesels would normally be operating. we INNER TURBINE BEARING (July 1994) The latest failure was a catastrophic failure of the inner bearing on July 5. It is suspected that a water seal failed and forced all the oil lubricant out of the bearing. The bearing heated up and seized on the shaft. The over temperature sensors were not functioning and the generator shut down. The project down time was 26 days. The cannery and the City diesels supplied the load during this time. The bearing and shutdown devices were repaired and the Hydro has been supplying the loads since July 31, 1994. The Insurance coverage minus the deductible paid for failures no. 1 and no. 3. Business Interruption coverage also helped with the City’s monthly payment during these outages. There have been other outages due to system electrical control problems during start up of large loads. These are typical for this size of a utility operation. There is a requirement to coordinate with the local operator so preparations can be made to start the large loads without effecting the City electrical system or customers. RECOMMENDATIONS The City is open to suggestions and help from almost any reputable source. However the solutions are not so easy since the required resources are not available in the City. The following is a list of items discussed with the council members for consideration: NEAR TERM 1. Provide back up support for the administrative and operations personnel. 2. Inspect the City distribution system and test all the revenue meters to reduce losses. 3. File all utility reports on time and send them to the proper designated place. 4. Reduce the accounts receivable and set up a system of collection that will be followed to reduce the debt owed the City. 5. Utility operator training can be provided to the City if they have qualified candidates. 6. Seek PPF Loan restructuring to enable the City to meet the obligation. us If possible, establish a Letter of Credit to back up payments and extraordinary expenses. LONG TERM LP Seek loan forgiveness from the state for the PPF Loan. 2. Consider an Administrator to provide the operation, maintenance, and administration of the utility system. Several options and firms have been mentioned that can provide these services. Local personnel can still be used to perform the daily requirements. 3. Develop new projects to benefit the City and Utility system. 4. Increase the City loads by getting the boat harbor funded and constructed. 55 Supply the school electricity at avoided cost in lieu of the diesel fuel being used for heating and hot water. 6. Increase the reservoir storage area to enable supplying more power to cannery during full production and allowing for system load growth.

By observing the remains of the bearing and housing, I would estimate that the assembly reached temperatures more than two thousand degrees Fahrenheit. While it is impossible to ascertain the events that led to this happening, clearly the bearing lost lubrication either through a leak in the bearing housing or by the oil being displaced by water. The high temperatures reached by the bearing, caused the bearings inner race to weld to the pelton wheel shaft. These high temperatures were conducted to the coupling. the damage observed was well beyond anything that could be repaired on sight. On a subsequent trip, the pelton wheel was removed and flown to Anchorage where it could be repaired by a qualified machine shop. After the pelton wheel was repaired, it was flown back to Larsen Bay for installation. All elements were reassembled and aligned to their proper locations. The generator was moved into alignment with the pelton wheel, with alignment requirements of the coupling manufacturing as a guide. The linear alignment was brought within .012" and the coupling faces were brought within .010" of being parallel. After starting, the plant appeared to be operating well and was free on unusual vibration or noise. The degree of damage would have been greatly reduced, had the bearing’s high temperature shut downs been operating. An error in the initial installation of the system, prevented the switch gear from detecting the bearing failure in its earlier stages. The system is designed to use a normally closed temperature switch that will shut down the system when the bearing reached temperatures that are obviously beyond normal. In the place of these temperature switches, an element was installed that changes resistance with a temperature reporting instrument. I would highly recommend that the system be configured to include the necessary switches. I have enclosed cut sheets for the bearing and the hytrel coupling as requested. I have recommended a semi annual maintenance program that would include checking alignment of all components and check the bearings etc. Thank you, ee Harlen Hansen Service Manager Enclosure ~ BROWNING, SKE oF “TORRINGTON PILLOW BLOCKS PRY-LUGIM assembly and mounting instructions pe © iy \ THE TORRINGTON COMPANY a SOUTH BEND, INDIANA 46634 ay 9 TELEPHONE 219-288-9161 © Copyright 1971, The Torrington Co. ASSEMBLY INSTRUCTION Se PREPARATION FOR MOUNTING Do not remove bearing from its package or wrapping until ready to assemble on shaft. Do not attempt to clean the bearing or wash out the preservative coating. STEP 1. Slide inboard triple labyrinth seal on shaft. This seal slides freely in- to position. STEP 4. Place the bearing on the adapt- er sleeve and locate at proper axial posi- tion on the shaft. STEP 2. Slide adapter sleeve onto shaft with threaded end to outside. Position sleeve at approximate bearing centerline. STEP 5. Place lockwasher against bear- ing with inner prong of lockwasher to- ward bearing and in slot of the sleeve. Tighten the locknut while periodically measuring the RIC until the proper re- duction of RIC is obtained See chart, page 3. Find lockwasher tang that is nearest a locknut slot and peen over into slot. STEP 3. Measure the unmounted radial internal clearance in the bearing by in- serting progressively thicker feeler gauge blades between the top roller and the raceway. The largest blade that will slide through is a measure of the radial int nal clearance (RIC). STEP 6. Slide outboard triple labyrinth seal onto shaft. Position both inboard and outboard seals to match grooves in housing. <= STEP 7. Thoroughly clean housing and remove burrs, if present. Oil the bearing seat and place shaft with bearing into the pillow block base. Carefully guide the seals into the housing grooves. STEP 8. If pillow block is to be axially fixed, insert stabilizing ring between bearing and shoulder on locknut side of bearing. NOTE: Only one fixed bearing should be used per shaft. Other bearing must be free to permit shaft expansion. Float bearing should be centered in the housing. _FOR ADAPTER MOUNTING STEP 9. Clean upper half of housing and oil bearing seat. Place over the bear- ing. To help prevent lubrication leaks, use a compound such as Permatex No. 2 between surfaces of the cap and base. The dowel pins will properly align the cap. NOTE: Pillow block caps and bases are not interchangeable.

The locknut should be tightened until RIC reaches approximately .003”’. .004”. MOUNTING STRAIGHT The mounting of straight bore SD bearings on a shaft re- quires the use of one of two methods. ARBOR PRESS METHOD On small bearings they can be pressed onto the shaft. A tube or pipe resting on the inner race is used to apply pres- sure to the bearing. An arbor press may be used to apply even pressure to seat the bearing firmly against the shoulder. BORE SD BEARINGS HEAT EXPANSION METHOD To mount larger bearings a heating method is used. The bearing is heated sufficiently to slide easily onto the shaft. One method is to heat the bearing in a tank of oil with a high flash point. The oil should not be allowed to exceed 250°F. The sketch above shows a typical heating tank. The bearing should not be in direct contact with the bottom of the tank or heat source. While the bearing is still hot it should be positioned squarely against the shoulder. Lockwashers and lock- nuts are then installed to hold the bearing against the shoulder as it cools. LUBRICATION The pillow block cap (upper half of the housing) has two tapped holes 30° from the vertical center line. One hole is in the center of the housing; the other is to the side. Lubricate through the center hole for the W33 style bearing (with groove around the outer ring). Lubricate through the side hole for a bearing without groove around the outer ring (plain O.D.). This is important! THE LUBRICANT WILL NOT GET TO THE BEAR- ING IF IT IS APPLIED THROUGH THE CENTER HOLE WHEN A BEARING WITHOUT A GROOVED OUTER RING IS USED. The selection of the proper type of lubricant and lubrica- tion system for spherical roller bearing pillow blocks is based on a combination of several factors depending on operating temperature, speed and design conveniences. GREASE LUBRICATION Since the simplest design that will accomplish the job is usually the best design, thought should first be given to the possibility of grease lubrication. The factors to be considered are: 1. Operating temperature should be below 200°F. 2. The limiting speed should be 50% of the value given in the tables of dimensions and capacities, which is for oil lubri- cation. 3. Correct type and grade of grease should used. 4. Correct quantity of grease should be applied. Applications utilizing grease lubrication should have a grease fitting in the center hole of the housing 30° from the top. The drain plugs located near the bottom of the housing allow purging of the old grease from the bearing. 5M-479-OST Relubricate at regular intervals to prevent damage to th bearing. Relubrication intervals are very difficult to determi because of variations of applications. If plant practice or perience with other applications is not available, consult your lubricant supplier. At least once per year the housing cap should be removed and caked or hardened grease should be cleaned out and then replaced with new grease. OIL LUBRICATION Oil lubrication will permit operation of spherical roller bear- ings at speeds and temperatures higher than those permissible with grease, but it is essential that the following points be observed: 1. Only high quality petroleum oil should be used. Petroleum oils of poor quality, animal oils and vegetable oils tend to oxidize easily and form sludge deposits on the bearing parts. 2. To provide an oil film of the correct shear strength, an oil with a minimum viscosity of 105 SUS at the operating tem- perature should be used. If the viscosity falls below this level, the bearing life will be reduced. 3. When circulating oil is used as a lubricant with a W33 bearing (with oil groove around outer ring), entry can be made through the center hole in the cap. The lubricant should exit from both sides of the base to prevent possible flooding, or the accumulation of too much lubricant on one side of the bearing housing. Drop-feed systems and mis systems should be adjusted on a flow versus operati temperature basis. Printed in U.S.A. Couplings Installation Instructions jute : ° | ‘Woods Sure-Flex \ Form 741D Sure-Flex flanges (outer metallic parts) and sleeves (inner elastomeric members) come in many sizes and types. First, determine the size and type of components being used. Remove all components from their boxes, and loosely assemble the coup- ling on any convenient surface. (Do not attempt to install the wire ring on the two-piece E or N sleeve at this time.) Also check maximum RPM values in Table 2 against operating speed. All rubber sleeves (EPDM and Neoprene) have the same ratings for a given size and may be used interchangeably. However, because rubber and Hytrel sleeves have completely different ratings, they never should be used interchangeably. Inspect all coupling components and remove 1 any protective coatings or lubricants from bores, mating surfaces and fasteners. Remove any existing burrs, etc. from the shafts. Slide one coupling flange onto each shaft, using snug-fitting keys where required. With the Type B flange, it may be necessary to expand the bore by wedging 2 screwdriver into the saw cut of the bushing. Position the flanges on the shafts to approx- 3 imately achieve the Gy dimension shown in Table 2. It is usually best to have an equal length of shaft extending into each flange. Tighten one flange in its final position. Refer to Table 1 for fastener torque values. Slide the other far enough away to install the sleeve. With a two-piece sleeve, donot move the wire ring to its final position; allow it to hang loosely in the groove adjacent to the teeth, as shown, fk at Slide the losse flange on the shaft until the sleeve is completely seated in the teeth of each flange, (The “G1” dimension is for reference and not critical.)

Box 876688 Wasilla, Ak 99687 Phone 907-376-9035 December 15, 1994 ay LARSEN BAY HYDROELECTRIC PROJECT JULY 5, 1994, TURBINE BEARING FAILURE 1.0 INTRODUCTION The Larsen Bay Hydroelectric generator tripped off line about 1600 hrs on July 5, 1994, due to failure of the inboard turbine bearing. The local plant operator notified the Alaska Energy and immediate action was taken to access the problem, notify Risk Management and the insurance carrier, and proceed to initiate repairs. 2.0 BACKGROUND The City of Larsen Bay is located on Kodiak Island. It is a remote community accessible only by boat or airplane. The primary source of electric power for the * community is the 475 KW hydro electric plant owned by the State of Alaska. The hydroelectric plant is operated by the City of Larsen Bay. Backup electrical energy is supplied by diesel generators owned by the City of Larsen Bay. Kodiak Salmon Packers, Inc. (KSP) seasonally operates a fish processing plant at Larsen Bay from mid May through September. KSP has its own diesel generators for the plant however, KSP purchases electrical energy from the City of Larsen Bay when the hydro plant is operating and energy is available. 3.0 CHRONOLOGY July5 Mr. Joe Katelnikoff of Larsen Bay notified Stan Sieczkowski, Alaska Energy Authority (AEA), that the inner turbine bearing failed about 1600 hrs. The city electrical needs are being met with diesel generation. Alaska Power Systems (APS) was contacted and asked to assist with repairs. (Attachment A) July 6 APS mechanic travels to Larsen Bay and dismantles unit. APS mechanic confirms inner bearing failed and seized to turbine shaft. July 12 APS authorized to proceed with repairs. (Attachment B) July 14 Turbine shaft is brought to Unique Machine in Anchorage for repairs. July 21 Work on turbine shaft is complete and necessary parts procured. APS a unable to travel to Larsen Bay on July 22 or 25 because of weather. LBOO4RPT.DOC Page 1 LARSEN BAY HYDROELECTRIC PROJECT JULY 5, 1994, TURBINE BEARING FAILURE July 26 APS travels to Larsen Bay. By 2200 hrs hydro turbine is repaired and test run. Turbine housing is resealed and unit is left off line to allow sealant to cure. July 27 Unit is returned to commercial operation. Hydroelectric Plant out of service for 22 days. 4.0 REPAIR COST The outside contract cost to repair the turbine was $14,645.00 (Attachment C) "- The total project costs are provided in the Insurance claim. 5.0 LOST KWH SALES The Larsen Bay hydroelectric plant was out of service for 22 days during the month of July 1994 as a result of the turbine bearing failure. The lost energy sales are shown in Attachment D. 6.0 DISCUSSION The inboard turbine bearing suffered catastrophic failure caused by loss of lubrication. (Attachment E) The loss of lubrication resulted in very high bearing temperatures which caused the inner race to seize to the turbine shaft. Also, the coupling which connects the turbine to the generator failed. The turbine shaft was repaired and a new bearing and hytrel coupling was installed. The unit was reassembled, realigned and returned to service. The unit appears to be operating with no unusual vibration or noise. LBOO4RPT.DOC Page 2 ay LARSEN BAY HYDROELECTRIC PROJECT JULY 5, 1994, TURBINE BEARING FAILURE 7.0 RECOMMENDATIONS Implement annual maintenance program to include: 1 Qe Alignment checks. Bearing checks. Testing of bearing thermal shut down devices. Semi-annual lube oil analyses. Vibration checks.

MEMORANDUM TO: Dennis McCrohan, Deputy Director (Energy) FROM: Stan UINUTeeeonse SUBJECT: Larsen Bay Hydro Turbine Bearing Failure on July 5, 1994 DATE: July 6, 1994 The Larsen Bay Hydro turbine inner bearing failed about 1600 on July 5. Mr. Joe Katelnikoff notified me by phone. The electrical needs are being met with the village diesels. Damage assessment is under way. Alaska Power Systems were notified and requested to assist in the repairs. A mechanic is to arrive in Larsen Bay at 9:30 AM today. He will tear down the unit to determine the extent of damage and repair parts needed. It appears that the bearing may have seized to the shaft. The local operator is to make a full report of the failure to me. I have notified Risk Management and Chubb Insurance of the failure. Based upon what we know at the moment, I expect the unit to be back in service by Monday July 11. ces Dan Beardsley, AIEDA Brad Thompson, Risk Management InterOffice Memo To: Stan Sieczkowski From: Remy See Date: May 3, 1994 Subject: Larsen Bay Cannery Circuit Breaker I spoke with Russel Higgins of Square D this morning concerning subject circuit breaker. Mr. Higgins said he checked out the circuit breaker by operating it at least 10 times and he said it worked fine. He pointed out that the breaker did not have a shunt trip coil and therefore you could not open it electrically. He did say that we could add a shunt coil if we wanted. (Cost would be $300 - $500) When I pointed out that we were also having trouble with the mechanical interlock and that it was keeping us from closing the breaker he said we could bypass that feature. After speaking with you, I again contacted Mr. Higgins and authorized Square D to install a shunt trip coil. The cost for pulling the cover off the breaker, installing the shunt coil and checking it out electrically will be about $500. The shunt coil will have to be ordered from the midwest, but he indicated he could get it in a day. When I asked, Mr. Higgins said that he had defeated the mechanical interlock when testing the breaker. I told him that we wanted the interlock to remain defeated. He said this could be done by installing a bolt. He said he would install the bolt and that he would put a tag on it saying he had done so at our direction. Mr. Higgins said he would contact us prior to shipping and suggested we arrange for shipping ourselves since we were more familiar with the transportation system here in Alaska. I told him that would be ok. NOTICE TO VENDORS NOT VALID FOR PURCHASES OVER $1,000.00 Please place the Purchase Request Number on your billing invoice.

We note that the bearings on the turbine were changed and the vibration problem addressed. There is still some vibration noted in the generator; however, the turbine was running smooth. Recommendation: 94005c.009 Spare parts and other items must be removed fom the electrical panel and this practice be discontinued in the future. The inside of the panel needs to be vacuum cleaned as well as the turbine building. While operation and maintenance checksheets were completed, we recommend that record keeping be expanded to include comments on day to day activites. Overall the facility was found to be in satisfactory condition. If you have any questions or if we can assist you in any way please let me know. Sincerely, Zt Gadling L. R.

I explained the Larsen Bay situation to Dan and asked him what his experience was with these bearings. Dan says they have had very little trouble with these bearings. When they do fail it is usually because of contamination. He could not recall a case where bearing failure has caused additional machine damage. But he did say it could cause alignment problems. I asked Dan if he was planning any trips to Alaska and if he would be willing to come up and change the bearing for us. He said he did not have any work scheduled for Alaska. He said that changing the bearing was fairly straight forward and he could talk someone through it over the phone and save us $1000 air fare and travel time.
