The village power plants and outside distribution facilites are owned and operated by the North Slope Borough (hereafter Borough). Both are also maintained by the Borough, utilizing either Borough personnel or, more recently, contracted parties. Although this report details problems encountered and operator concerns, the Borough provides the villages with very reliable electric power and the overall condition of the systems is good. The Borough is currently funding Village Water and Sewer projects in these villages. The construction of water and sewer treatment plants, distribution piping and associated equipment and heat trace has added considerably to the electrical load in the villages and dictated that most of the village power plants be coincidentally upgraded. The extent of these upgrades is subject to available funds and need priorities and is discussed below by individual village. All Borough plants outside of Barrow currently use diesel generators. This fuel is very costly to import and transportation logistics can be quite difficult. To offset some of these costs, power plants supply waste heat to at least one other building. Anaktuvuk Pass and Point Hope utilize waste heat to the greatest extent and consideration should be given to maximize heat recovery in each village. Potential candidate buildings are discussed below by village. The estimates herein of current fuel savings accomplished by use of waste heat were obtained from Borough personnel in the respective villages. Maintaining dependable, trainable operators for all shifts continues is a problem in several villages. Generally, one and occasionally two of the operators carry most of the responsibility for keeping the power plant operational and have the knowledge required to restore the plant if an outage occurs. Handling and disposal of waste oil is a Borough- wide concern. Very few of the villages have waste oil burners and the stockpile of used oil is growing across the North Slope. Waste oil blenders have been installed in every village, although the only blending system currently in full use is in Nuiqsut. The other villages either do not operate the blending systems or utilize them on a very limited basis, typically one hour per day. The operators offered various reasons for not using the blending systems but excessive soot in the plant was the primary complaint. Tuning and use of these blenders would be a step forward in dealing with waste oil in the Borough. Regularly scheduled preventative maintenance and documentation were identified as primary concems. There is no formal written procedure and any posted schedule for maintenance is updated by one or two key operators. Often, there is no posted due date for the next servicing; if the core operator should leave, this mental schedule would be lost. Maintenance performed by operators is limited to oil, oil filter, fuel filter, and air filter changes. NC Machinery and Pacific Detroit Diesel mechanics perform more intensive servicing such as valve adjustment, bearing replacements and engine overhauls, although the exact schedule was not determinable from this visit. Operators in villages with older power plant equipment were found to be more concious of the need for preventative maintenance. It is highly recommended that the Borough devise a maintenance schedule organized by engine serial number for posting and require maintenance reports on a regular basis. This will extend the life of older facilities and prevent unnecessary aging of the many new generators being installed throughout the Borough. It is recommended that the Borough continue with diagnostic oil samples for each generator at each oil change. Old records for these samples were observed in Wainwright and Nuiqsut. Operations records could be beneficially augmented with recording bus voltmeters to track any outage times. Evidence of periodic fire alarm system testing was not observed in the plants. Only Nuiqsut, Kaktovik and Point Hope had operational fire alarm systems. The system in Point Hope does not report alarms to the Borough Fire Department. This is a life/safety issue and a method for testing and recording operation should be implemented. There is currently no provision for hydrogen gas detection near the battery banks and this should also be installed. The Borough power plant operators fill in a standardized Daily Operators’ Log for each of the three eight-hour shifts per day. This log is based on hourly totalizer meter readings and also has provisions for recording problems. Operator meter reading proficiency is acceptable. Most of the plants have a standardized log for recording fuel consumption, based on day tank fuel meter readings, and a log for recording added oil/glycol to maintain correct levels for these fluids. Power outages are reported on a standardized form, as well. Introduction of any new recording forms would require adoption and distribution by the Borough Village Services Director. The outside electrical distribution equipment is in good condition overall. Overhead conductors are properly sagged and few poles are leaning away from perpendicular. Villages closest to the ocean naturally have the highest level of meter base corrosion. Wainwright has several meter bases which are corroded enough to allow a person to insert his/her hand into the meter base. Point Hope experienced an outage this past summer due to corrosion at a distribution transformer terminal. Distribution voltage varies from 2400 VAC to 12470 VAC in these villages, making standardized fusing and stocking of replacement parts difficult. A summary of the point scores associated with the Electrical Utility Evaluation system are included in the Field Trip Report for each village. Appendix A contains the evaluation forms for each village. nN Field Trip Report Wainwright, Alaska October 16, 2000 Contact was made with George Patkotak, lead Power Plant Operator. At the time of this Visit, installation of a new 910 kW Caterpillar generator set was nearly complete and Generator #2 was out of town for overhauling. The fire detection system for the plant was also being upgraded. Peak demand for the two months previous to this visit has ranged from a low of 562 kW to a high of 871 kW. This figure can be expected to increase as the colder winter months set in and heat tracing associated with the water and sewer facilities is tumed on. With the exception of new Generator #5, the generators in Wainwright have high hours with two of the units exceeding 40,000 hours. Ventilation in the plant is not adequate. The doors must be open continually to avoid generator overheating and shutdowns. The mezzanine containing the radiators is extremely hot. The operator explained that the ventilation exhaust is located above the ventilation intake and that hot air will continually circulate if a plywood barrier is not maintained for some separation. Ventilation will increase in importance when the new generator becomes operational. When operating correctly, waste heat is provided to the Department of Municipal Services (DMS) building, located near the power plant. The operator stated that the waste heat system on the DMS side of the exchange is not working properly and that the boilers in that building are providing much of the required heating. The DMS building is aging and strong consideration should be given to adjusting and upgrading the heating system to take full advantage of the power plant waste heat. During summer hours when the heating demands of this building are lower and waste heat is not exhausted, ventilation is again a concern. The new sewage treatment plant is close enough to warrant an engineering analysis of waste heat facilities. Several homes have severely corroded meter bases, as shown in the accompanying digital photographs. The close proximity of Wainwright to the ocean results in rapid corrosion of metallic equipment. Note the corrosion beginning on the water/sewer homeowner control panel adjacent to the new water/sewer meter base. This corrosion has taken place in less than two years. Disposal of waste oil and oily rags was brought up as an operator concern. The accompanying photo demonstrates the need for an upgrade to the waste oil blending system. Open buckets containing varying amounts of waste oil are stored within the facility. George Patkotak is to be commended on his outstanding efforts in operating the Wainwright Power Plant. He has taken the initiative to teach himself about the computerized environmental controls and engine monitoring system, has kept maintenance records and has displayed the ability and desire to learn about plant equipment details as well as the overall operating scheme. The following is a summary of outages in the 12 months prior to this site visit. There were no records of outages in the current year. Date Duration Cause of Outage 10/13/99 1 min Feeder breaker tripped allowing generator #3 to be serviced for a leaking o-ring in thecooling system. 11/03/99 1 min Operator caused outage by testing demand configuration. 11/03/99 1 min Possible problem with generator #1 breaker. 11/07/99 1 min Feeder circuit breaker tripped due to underfrequency while performing an oil change on generators #3 and #4. 12/22/99 % hour Shift operator did not report for work. George Patkotak was called to work during day off and restored the plant.

OTHER REPAIRS NEEDED: See Frehol Trp he port, Field Trip Report Nuigsut, Alaska October 18, 2000 Contact was made with Sam Kunaknana, lead Power Plant Operator. The power plant in Nuiqsut is new and went on-line approximately a year ago. Two new 910 kW and two new 450 kW Caterpillar gensets, providing a generating capacity of 2720 kW, have sufficient capacity to support this fast-growing community. Peak demand for the two months previous to this visit has ranged from a low of 499 kW to a high of 669 kW. The capacity of this plant is adequate to support anticipated community growth due to the Alpine oil field and the ongoing construction of water and sewer facilities. There is room in the plant for two additional generators. Provisions exist in the switchgear for two future generators. Several problems were described by the Lead Operator. The day tank in the new plant is filled with two pumps located in the old water treatment building. The impellers continue to rotate after the motors have stopped running when a full tank is being accessed, which causes fuel to continue to flow into the day tank until the overfill protection is activated. The pumps are not sized adequately for the new facility; the operator claims that new motors and pumps are scheduled to be installed. There is no primary filtering on the tanks in the tank farm which feed the day tank. Particles occasionally get caught in the fuel meter, causing the meter to stop functioning. The ventilation louver on the West side of the generator room does not work. The operators open the overhead door in varying amounts for ventilation. Apparently there is no thermostatic switch controlling this louver. The ventilation fan on the East side of the generator room is not functioning due to a broken belt. The operator stated that a replacement belt is on order. Generator #1 has been run as the primary unit since power production was turned over to the new plant. This generator is closest to the wall away from the overhead door in the generator room. High water temperatures have occasionally caused this generator to shut down and Generator #2 to go on-line. This happens more frequently in the warmer months when the school demands less waste heat in combination with higher ambient temperatures. As mentioned above, waste heat is currently provided to the school and old water treatment plant and washeteria, located near the power plant. The new water treatment building is also near the power plant and waste heat should be considered for this facility, as well. The operators have requested that a maintenance schedule, reporting documentation and necessary training be provided by the Borough. 13 There have been no power outages this past year with the start up of the new plant. The plant is clean, organized and well kept. Maintenance documentation is the only outstanding organizational issue.

The power plant in Kaktovik is new and went on-line September 12, 2000. Two new 910 kW and two new 450 kW Caterpillar gensets, providing a generation capacity of 2720 kW, have been installed. Contractors were completing several remaining items including commissioning of a 10 ton overhead crane and operator familiarization training on the HVAC system controls. Although this power plant is new, the level of organization and cleanliness is much lower than that seen in the other villages. There was considerable construction debris, personal equipment, rags, scrap board insulation and other items throughout the tank room, generator room, shop and kitchen area. Should quick action be necessary in an emergency, these items could present obstacles to movement. Documentation from the old power plant is limited to one log book with very little documentation of metering or maintenance. Outside of the Borough daily operator log, there is no documentation system in place. The generators are new enough so that only one oil change has taken place, this on Generator #2 at 500 hours of operation. There is no documentation associated with this event. There are fuel oil leaks at the day tank pumps; the mechanical contractor is aware of these and is planning on correcting this problem. Onshore prevailing winds make this location notorious for rapid corrosion of outside equipment. Note the corrosion on one of the distribution transformers in the accompanying photos. Peak demand for the two months previous to this visit ranged from a low of 426 kW toa high of 534kW. The capacity of the new plant is adequate to support growth of this community for the life of the plant, including scheduled construction of water and sewer facilities. The design of the Kaktovik plant is nearly identical to the Nuiqsut plant. However, there was no fuel meter piped into the day tank and the operators are tracking fuel delivery. The overhead louver and ventilation fan were working at the Kaktovik plant and ventilation was very good. Waste heat from the plant has been piped to the existing heat. exchanger in the old power plant. This exchanger provides heat to the school, washeteria and water plant. The village services superviser estimates a savings in fuel oil consumption of between 15,000 — 20,000 gallons per year. The new power plant was built across a gravel pad from the village services building. This facility could be provided with waste heat for additional fuel oil savings. There has been one power outage involving the new plant equipment since power production was transferred last month. This occurred on October 18, 2000 when the HVAC technician performed a controls communication module reset/fire alarm reset. This caused a fire alarm ON condition and shut down Generator #1. The fire alarm system prevented Generator #2 from starting and a five minute power outage resulted. 20 The “Demand Start Failure” annunciator button in the master control section of the switchgear was still illuminated the two days after this event. As in the other villages, the operators have requested that a maintenance schedule, reporting documentation and necessary training be provided by the Borough. There are currently very few tools available to the operators. The following is a summary of outages in the 12 months prior to this site visit, based on available records during this assessment.

The plant was in very good condition. This plant was constructed in 1994 and care has been taken to keep the plant clean and organized. Peak demand for the two months previous to this visit has ranged from a low of 337 kW to a high of 520 kW. This figure can be expected to increase as the colder winter months set in; temperatures are lower in this interior region of the Borough. The operator claims that approximately one-third of the houses in Anaktuvuk have had above-ground connections made to the water/sewer system. These connections are heat trace intensive; the operator indicated that the electrical load increased by 100 kW with the addition of 19 above-ground connections. All fuel must be flown into Anaktuvuk Pass, which is very expensive. Waste heat is currently supplied to four buildings including the Department of Municipal Services (DMS), the Fire Station, the new Sewer Treatment Plant, and a large, new warm storage building. These buildings are all located near the power plant; the school is some distance from the power plant but an engineering analysis to determine waste heat capacity of the plant and other facilities which might benefit from waste heat should be included with any power plant upgrades. Current waste heat usage saves approximately 24,000 gallons of fuel oil annually. The lead operator is very conscious of preventative maintenance, though no written plan is in place. Oil samples are sent to an NC Machinery lab for each generator at each oil change. Maintenance performed is similar to that named for other villages herein; however, records are available for this plant and greater attention to detail appears to be taken in the overall operation of this plant. Emergency lighting and exit signs are installed and operational. The fire alarm is test approximately every two months. Ventilation in this plant is adequate and effective. The outside electrical distribution equipment is in very good condition and is not subject to the level of corrosion present in the coastal villages. The meters and transformers are in good condition, conductors are properly sagged and separated and anchors are properly installed. The waste oil blending systems were taken off-line due to soot problems throughout the plant when this system is operated. Waste oil is pumped into two drums located near the day tank. When these tanks are full, Borough personnel take the oil to the Operations and Maintenance shop for use in a waste oil burner. 29 The following is a summary of outages in the 12 months prior to this site visit. Date Duration Cause of Outage 11/02/99 1 min Operator disconnected pre-expansion tank alarm to change probe assembly. Operator did not believe this would cause an outage, as the low glycol alarm probe assembly had been changed before without affecting operations.

HEATH AND SAFTY ISSUES: None. OTHER REPAIRS NEEDED: None Field Trip Report Atqasuk, Alaska November 7, 2000 Contact was made with Melvin Wong, lead Power Plant Operator. The plant was found to be in good condition. This plant was constructed in 1985. Atgasuk is the smallest community in the Borough. Peak demand for the two months previous to this visit has ranged from a low of 303 kW to a high of 510 kW. Construction of the Water and Sewer Project was underway at the time of this visit. None of the associated heat trace or process electrical equipment is operational, which means the current electrical demand can be expected to increase dramatically. Generator #3 is normally run as the prime unit. Generator #1, at 275 kW, is the smallest of the three generators and is used when maintenance is being performed on Generator #3. It is uncertain whether the current generating capacity of this plant will be sufficient to support the additional electrical load due to Water/Sewer facilities. Synchronization of the generators is not complete. The lead operator claims that the current PLC programming requires that all generators be set to manual control in order to shut down Generator #3 for maintenance. Fuel transportation to Atqasuk is accomplished overland in the winter with rollagon equipment. Waste heat is currently supplied only to the washeteria, which is connected to the power plant. Due to the compactness of the community, waste heate could easily be supplied to the Clinic, Community Center, and Fire Station. The School and Municipal Services buildings could also be considered, but are slightly further away than the three previously mentioned facilities. The waste heat capacity of the power plant would probably be the limiting factor, rather than distances involved. Current estimated fuel savings are approximately 750 gallons/month. The lead operator is very conscious of preventative maintenance, though no written plan is in place. Oil samples are sent to an NC Machinery lab for each generator at each oil change. Maintenance performed is similar to that named for other Borough villages. Oil change and fuel consumption records are available. Waste oil is a particular problem in this village. Barrels storing waste oil number more than one hundred near the landfill. As shown in the accompanying photo, waste oil is stored in various containers within the plant building, in connex units near the plant, and on the ground outside the plant. The waste oil blending system in the plant is used no more than one hour a day due to soot problems. As in the other villages, this may be able to be improved with tuning. There is no waste oil burner available in Atqasuk. Emergency lighting and exit signs are installed and operational. There is no operational fire alarm or suppression system in the plant. Ventilation in this plant is adequate and effective. There are two portable eyewash stations in the plant. The age of the generators and plant facility is apparent. The wooden floor is buckling and cracking in some locations and the finish is chipping off, leaving exposed wood. A very strong diesel smell was present near the day tank. This is apparently due to leaking 38 threads at pipe joints and cumulative small spills. The fumes were strong enough to make it very uncomfortable to be near the day tank. Glycol leaks are present at the © breather tubes. Various small leaks and drips make drip pans and containers necessary near and under the generators. The outside electrical distribution equipment is in very good condition. Atqasuk is approximately 50 miles from the coast, which reduces the corrosion rate of outside equipment. Meter bases show only minor corrosion and no corrosion was noted on the pole transformers. The following is a summary of outages in the 12 months prior to this site visit. Cause of Outage Power outage for 20 buildings due to two blown fuses and a jumper problem at a pole. Scheduled outage for transformer replacement. Scheduled outage to connect new sewer treatment plant to power grid. Shutdown due to low voltage. Day tank low on fuel. Operator trying to drain tank as low as possible. Scheduled outage to connect new lines and transformers. Scheduled outage to relocated some overhead lines. Blown fuse on one phase at transformer serving school. Outage due to blown fuse, affecting Block 4.

See Field Trp Report. 46 Field Trip Report Point Lay, Alaska November 8, 2000 Contact was made with Julius Rexford, lead Power Plant Operator. Three new generators have been recently installed. Work was being done in preparation for overhauling one of the two remaining older generators. The age of this plant is very apparent. Peak demand for the two months previous to this visit has ranged from a low of 431 kW to a high of 523 kW. Four of the five generators are normally run during colder periods. The Village Water and Sewer project is nearly 100% complete in Point Lay. Several buildings have not been connected and no definite plans to connect them exist. Waste heat is currently supplied only to the washeteria. Potential buildings that could be served by waste heat include the municipal services building, the new water and sewer plants, the Borough operations and maintenance shop, and the clinic. Current waste heat usage saves approximately 750 gallons of fuel oil per month. The maintenance scenario for Point Lay is similar to the other Borough villages and is limited to oil and oil/fuel/air filter changes. Oil samples are sent to an NC Machinery lab for each generator at each oil change. There are various glycol leaks in this plant, including the breathing tubes and radiators for generators #2 and #3. Waste oil facilities are similar to those discussed for the other Borough villages. Doors in the plant do not seal, causing the noise level to be quite high in the office, adjacent to the generator room. The double doors in the generator room loading area, shown in the accompanying photo, do not close, causing winter storms to blow into the building. Various oxygen bottles for gas welding tank are located immediately outside these double doors, which is a typical example of the upkeep problems. Although snow prevented location of most spills outside the plant, a spill was located on a patch of gravel under a drum. It is well known that Point Lay has the harshest winter weather of all the villages in the Borough, often making construction and maintenance difficult. There is very limited space in this plant and ventilation is a problem in the summer months. All doors must be kept open, which clogs the radiators with dust, which leads to more generator cooling problems. The ventilation circulation problem described for Wainwright applies to Point Lay, as well, due to similar construction of the exhaust and air intake facilities. High temperature shutdowns of generators is a common occurrence in the summer months. Various other problems include electrical outlets which are falling apart and pose a shock hazard at generator units #3 and #4, exposed wiring supplying a waste heat pump, and soldered copper fuel lines supplying the generators units from the day tank which should be replaced with lines more suitable for supplying diesel fuel (see accompanying photos). The backup waste heat circulation pump should be reinstalled, as failure of the primary circulation pump will cause overheating problems. The operator claims that the 47 generators are running out of sequence and should be corrected by reprogramming the controller in the switchgear. There are no eyewash stations installed in this plant. The waste oil blending systems was taken off-line due to soot problems throughout the plant when this system is operated. Waste oil is pumped into two drums located near the day tank. When these tanks are full, Borough personnel take the oil to the Operations and Maintenance shop for use in a waste oil burner. The following is a summary of outages in the 12 months prior to this site visit. Date Duration Cause of Outage 1/31/00 3 min Operator-caused outage; wrong generator was taken off line in preparation for oil change. 5/24/00 3 min Village breakers tripped without warning. Problem unidentified. Problem continued throughout morning. 5/25/00 2 min Village breakers continue to trip. Borough personnel on site for troubleshooting. 7/20/00 2 min Under frequency, low voltage, high temperature alarms on generator #2.

Overall, the plant was found to be in very good condition. The power plant consists of an older building and an addition which was built in 1996 and is referred to as the new plant. The original building has five generators and switchgear, while the new plant contains two 665 kW units and updated switchgear. The two bus sections are intertied, with an electronic power metering section located in the newer switchgear. Point Hope is the largest village on the North Slope, exclusive of Barrow. Peak demand for the month previous to this visit has ranged from a low of 677 kW to a high of 936 kW. The Village Water and Sewer project is nearly complete in Point Hope. The operator indicated that ‘the peak demand during December, January, and February is approximately 1015 kW. With the exception of Generators #4 and #7, the generators in Point Hope have high hours with four of the seven units exceeding 30,000 hours. There is a pad located in the new plant for one additional generator. Waste heat is currently supplied to the school, laundromat, senior center, and clinic. These facilities are large, due to the community size, and waste heat provides a fuel savings of approximately 51,000 gallons of fuel oil. As the village and power plant capacity grows, other nearby facilites that should be given consideration for waste heat service include the Public Safety Officer building and the city office. There are separate day tanks, lube oil tanks and waste oil blenders in the two plant sections. As in most of the other villages, the waste oil blenders are not operated. The operator did not give a complete explanation for this, but indicated that the blending units are functional. Waste oil is accumulated in drums which are promptly picked up by Borough village services personnel for stockpiling and/or use in one of two waste oil burners in the village. : The fire alarm system, consisting of smoke and heat detectors, is only partially operational. On several occasions, false alarms have occurred, but were not received by the fire department. Emergency lights, exit signs, and eye wash stations are installed. The extent of maintenance performed is the same as that mentioned for the other villages; however, the lead operator has kept maintenance records for all the generators, fuel and glycol usage records and has kept the generators and plant clean and drip free. There are no signs of spills or leaks, aside from Generator #7, which is leaking slowly from the bottom of the crankcase. NC Machinery is aware of this and will service this unit at the next oil change. The equipment grounding conductor for the frame of Generator #2 is partially severed where it enters the concrete floor (see accompanying photo). A small leak and corroded terminals were found at the battery bank for Generator #1. 39 George Koonaloak is to be commended on his outstanding efforts in operating the Point Hope Power Plant. George has taken much of the responsibility for keeping the plant clean, organized, and functioning smoothly. The following is a summary of outages in the 12 months prior to this site visit. Date Duration Cause of Outage 5/12/00 5 min Generator #4 tripped due to over voltage. Apparent cause was a surge in the laundromat facilities. 5/13/00 5 min Circuit breaker feeding the school tripped. The bus under frequency trouble light was the only indication. 5/15/00 5 min Same as school outage on 5/13/00. 6/14/00 6.5 hrs Arcing caused by corrosion at the west village feeder transformer. 11/09/00 1 min No graveyard shift operator. Generators #3 and #6 breakers were tripped and generator #6 under frequency trouble light was on.
