Correct the report title and the date on pages ii thru 6. 2. On page 5, double check the type of fuel oil used by KEA. I was under the impression that they heated the fuel oil so that they could use No. 2 rather than No. 1. Also correct the typo in the first paragraph on this page. 3. On page 65, correct the labelling of the raw water line. 4. On page 71, show where the arctic piping enters the building and the proposed routing within the building. 5. The arctic pipe sizes in the ’Raw Data’ portion of the Appendix shall never be found by most readers. Indicate the location of this information on page 48 or page 50.

The $1.15 million for a waste heat recovery system connection to the water treatment plant in Kotzebue is a good ball park number if only the water treatment plant is connected. The system shall likely also supply heat to the new hospital and other facilities as heat availability allows. The total system cost shall probably be two to three times this $1.15 million dollar figure. It would be best to mention this to avoid future confusion. 2. See the Noorvik Waste Heat Recovery Report for a more accurate estimate of a waste heat system in this location. As mentioned in the note with the report the high school would use most of the available waste heat. For a useful connection to the water treatment plant it would be necessary to forgo connecting the high school. A waste heat system in this configuration would cost around $400,000. 3. The waste heat recovery system in Shungnak is the property of the Alaska Energy Authority. This means it is the responsibility of the Energy Authority rather than the city, AVEC, and school district to repair the system. I shall be in Shungnak checking what needs to be done for the system on March 13 & 14. The school district has indicated in a telephone conversation that the glycol in the system was replaced with water before the system went down. If this is the case then it shall not be possible to reactivate the system before this summer. If you have any questions, feel free to give me a call. MAR O93 °S0 15:04 TOP DEMO 3150 “C" ST.

Note that the Kotzebue study is overly optimistic about the amount of waste heat available from the power plant and perhaps underestimates the cost of installing the system. An engineer for KEA has indicated that the amount of waste heat available is about half of that indicated in the study. The Alaska Energy Authority is having a revised study done that shall be complete at the beginning of April. The new study shall not indicate connections to nearly as many end use facilities as this current study does but shall include at least the new hospital and the water treatment plant. Note also that the Noorvik study indicates that the most economical waste heat system at this site would only serve the high school. Details for connecting to the water treatment plant, the plant’s fuel use figures, and analysis of the potential savings for the plant are included in the report, but the high school is closer to the power plant and can use all the available waste heat in the winter. If you have any questions, feel free to give me a call.

Alaska 13 Kotzebue Prepared by Thompson Engineering Company, Inc Consulting Engineers Eagle River, Alaska February 1990 II. Kotzebue Electric Association Waste Heat Recovery for District Heating February 27, 1990 Revision 3 Purpose The purpose of this report is to evaluate, for the Kotzebue Electric Association (KEA), the Fotzebue District Heat Study prepared for the Alaska Energy Authority. This study was prepared by Polarconsult Alaska, Inc., to determine the preliminary economic viability of district heating utilizing waste heat from the Kotzebue Electric Association power plant. This evaluation was conducted to verify the initial results of the original study or identify discrepancies that would affect the viability of the project. This evaluation takes into consideration the actual capabilities of the power plant and incorporates the utilities previous experience in waste heat recovery. Summary and Recommendations The maximum waste heat that is available from Kotzebue Electric Association on a continuous basis is approximately 2.355 million Btu/hr. The waste heat that will be recovered is from the engine jacket water system. Waste heat recovery using exhaust boilers is not economical. The recoverable waste heat is sufficient to provide service to the new hospital. While no other services are planned in the initial phase, the installation should be sized for future growth. Future services can be added as the base load on the power plant increases. The estimated installation cost for this initial loop is $950,000. The fuel savings for supplying this heat to the new hospital is $202,600. The 0 & M costs are approximately £147,000 per year. The fuel savings generated by utilizing the waste heat from the power plant will be shared between KEA and the community. KEA will not be able to provide waste heat to the community for free. However, costs charged by the power Plant that are above the installation, operation, maintenance, and interest will be returned to the community in the form of reduced future electrical costs or as capital credits. ‘take Concerns with the District Heat Study The Kotzebue District Heat Study (DHS) prepared for the State of Alaska, Alaska Energy Authority, has stated that the recovery of waste heat from the Kotzebue Electric Association power plant can save the community of Kotzebue $711,100 per year in fuel costs. While there are significant savings to be obtained, the savings are not of this magnitude. Some of the problems in the DHS that have been identified are as follows: 1. Waste Heat Availability - The District Waste Heat Study indicates that 6.8 million Btu/hr is recoverable from the KEA power plant. Our calculations for the maximum continuously 1 available recoverable waste heat currently available, based on the continuous base power load of 1.5 MW, indicate that 6.9 million Btu/hr of waste heat is generated. However, the efficiency of this type of recovery system is 70% and the Power plant currently uses 1.2 million Btu/hr for fuel and space heat. This leaves only 3.6 million Btu/hr for other uses. To recover the 3.6 million Btu/hr on a continuous basis exhaust boilers would be required on each of the units. The waste heat that is recoverable from these boilers is 1.25 million Btu/hr which is equivalent to 114,000 gallons of fuel per year. However, the operating, maintenance and interest costs to recover this waste heat using these boilers will exceed the savings in fuel. See Appendix A for calculations. Therefore, the total continuous waste heat that can be recovered economically is 2.35 million Btu/hr and this waste heat will be recovered from the jacket water systems of the power generation units. The waste heat that is available on a continuous basis will increase as the base load on the power Plant increases. For example; the base load on the power plant is expected to increase with the addition of the hospital electrical load. Additional waste heat is available on a non- continuous basis as the electrical load on the Plant is increased above the base load due to seasonal fluctuations. Fuel Costs - The District Heating Study uses the retail cost paid by small fuel consumers ($1.30 per gallon) and the fuel cost for KEA (#0.62 per gallon) as factors in the economic justification for the project. The actual price that KEA paid for fuel in 1989 was $0.68 per gallon. The community currently pays $1.30 per gallon of fuel. If a bulk fuel storage facility were to be installed, then bulk fuel could be purchased from the Bureau of Indian Affairs for #1.07 per gallon (based upon the Alaska Resupply Operation 1989 tariff). Costs for operating and maintaining the a bulk fuel facility would have to be added to the fuel price. In addition, environmental concerns such as oil spill contingency, containment, and clean up, must be addressed and the proper permits) and approvals must be obtained from State and Federal Governments. For the purpose of the study, it is recommended that the maximum price of fuel used to calculate the savings generated by the waste heat system should be #1.07 per gallon. , Piping Installation Costs - In the District Heating Study the cost of installing the piping system is under-estimated. The cost estimate in the District Heat Study indicated that the cost for the complete installation of the 8 inch piping in a 3 foot deep trench is $15.00 per foot. The actual costs, experienced by KEA, for digging a trench 18 inches wide by 3 feet deep for the installation of electrical services is, $12.00 per foot. The trench required for the installation of two 8 inch diameter insulated pipes will be 4 feet wide by 3 feet deep and will cost approximately $30 per foot. We estimate that the cost for installing a single 8" diameter pipe is #10.90 per foot. In addition, the installation of geotextile fabric, the connection of the wiring and the insulation of the joints must be included in the installation cost. A total installation cost of $50.00 per foot of pipe is more reasonable. Another discrepancy noted in the estimates is that the quantities for the piping are shown as "one way" and the material costs have been doubled to achieve a true cost; however, the installation costs have not been increased to reflect both a supply and a return pipe. Operation and Maintenance Costs - The costs to operate and maintain the heat loop system are under-estimated. The total cost for operation and maintenance of the "School loop" (includes the new hospital) in the District Heating Study is estimated at #17,220 per year. Our estimated 0 & M cost for providing waste heat to the hospital is #147,000 per year (this cost includes a 1.4 factor for contingency which is required by REA on operating costs). Our calculations indicate the cost to provide the power for pumping alone is #55,000. The estimate for annual operation cost in the District Heating Study does not include any costs for cleaning of the heat exchangers, annual hydro- testing of the piping system, or the cost of maintenance or replacement of the pumps. Our O & M estimate is included in Section VI. The utility rates for the cost of the waste heat sold must include the operating and maintenance costs, the cost of replacement of the equipment after its economic life, and the margins required for the utility to maintain its equity position. These costs must be included in any -economic evaluation of this project. Thermal Considerations — The excavation limits shown for the installation of the heating loop piping may be under~-estimated. The burial of the heat loop piping will cause a thaw bulb around the piping. In order to prevent settlement of the piping or the ground around the piping the thaw bulb must be contained in = non frost susceptible soils. The excavation required will. depend upon the local soil conditions but will likely exceed the limits indicated in the District Heat Study. IV. Plant Modifications i. Parallel Radiator Operation —- The existing jacket water cooling system will be modified to allow for a common jacket water supply and return header. This will benefit the power plant operation by taking advantage of free cooling as well as provide a common system for waste heat recovery. Provisions For The Addition Of A New Radiator - The design of the parallel radiator loop should provide for the addition of a future radiator. The radiators on units 3 and 4 are small, obsolete, and their condition is such that additional repairs and maintenance are not economical. These radiators will not be connected to the parallel radiator loop. The total capability of the existing radiators to reject jacket water heat without the unit 3 & 4 radiators is 6.1 MW. The total jacket water heat that can be generated by the engines will be 7.1 MW with the addition of the mew generator in 1990. (This assumes that all engines are running at full capacity) However, it is not necessary to provide heat rejection for the total capacity of all the engines but only for the peak electrical requirement. In order to maintain first contingency firm power generation it is mecessary to provide sufficient radiator capacity to carry the peak generation loads with the largest single radiator out of service. With this requirement the maximum radiator capacity is currently 3.8 MW. The March 1989 Power Requirement Study projects that a peak of 3.8MW will occur in 1992. At that time additional radiator capacity will be required. Engine Temperature Elevation i The operating temperature of the engines will be elevated from 165 to 195 degrees Fahrenheit. This will allow the waste heat ~ system to provide heat at the same temperatures for which the building systems were designed. Exhaust Boilers - If waste heat recovery is required from the exhaust systems, then it will necessitate new waste heat recovery units on each of the generators. The existing heat recovery boilers are limited toa maximum working pressure, when new, of 25 psig. The fluid pressure in the heating loop at the boilers will exceed this pressure limitation. An exhaust diverter system will be required to control the flow of exhaust into the recovery units to limit the temperature of the heating loop. In addition, exhaust temperatures must be maintained above 350 degrees Fahrenheit to prevent condensation of sulfuric acid. The amount of heat that is recoverable from the exhaust on the engines is not steady state. The temperature of the exhaust generated, and the total mass flow of the exhaust, fluctuate based on the load on the engine. These temperatures can range from 1000 degrees to less than 500. Insulation of Existing Heating System - In order to provide the maximum amount of waste heat for the district heating system, it will be necessary to minimize the losses in the power plant. Insulation of the existing heating system will minimize the in-plant losses. Heat Exchanger and Fumps - The waste heat recovery for the district heating system will be provided through a plate heat exchanger in the power plant. The jacket water will be pumped by a separate pump through this exchanger and back into the jacket water cooling system. An additional pump will be required to circulate the district heating loop. The pumps and the exchanger should be sized to allow for the expansion of the district heating system as additional waste heat is generated by increases in the base power demand. The supply water will be provided to the hospital at approximately 192 degrees and the return to the power Plant will have a temperature of approximately 180 degrees. Cooling the water below this temperature will cause the engines to start to recycle the jacket water and reduce volume of the high temperature water supplied to the heat recovery exchanger. This reduces the amount of recoverable heat. District Heating Loop - The district heating loop will use treated water for aheat transfer fluid. The treatment will prevent corrosion of the piping and the inhibition of bacterial growth. The temperatures of the water will be high enough that treatment of the water will be required to prevent precipitation of organic materials in the water and required to eliminate dissolved oxygen. Heat tracing will be provided on the heating loop’ for freeze protection. The heat tracing will be thermostatically-controlled and designed to alarm if it is not operational. The installation of the piping system will be evaluated to determine if the system should be installed above the ground or buried. If the line is buried it may be necessary to over-excavate to provide a stable non frost susceptible non settling foundation in the thaw zone caused by the hot piping. Economic Evaluation An economic evaluation of providing waste heat to the hospital has been prepared. This evaluation shows that, with the price of fuel at $1.07 per gallon, the project has a positive net present value when the combined interest and inflation/escalation factor is 9.5%. See Table 1 and Figure 1. The price of the fuel in the case above is based on the assumption that the Hospital will install bulk fuel storage capacity and that it can purchase BIA fuel. If the hospital does not install bulk fuel storage and must purchase fuel at retail. prices then the net present value of the projects will be even greater.

We have made some assumptions regarding the type of report we expect to provide as a final product. In most cases, these assumptions have been that we will provide a product consistent with those we have done for you such as Noorvik, Glennallen, and Sand Point. Some of report’s key features include building descriptions which consist of narratives, photographs, and AutoCAD drawings of the simplified floor plans and heating system schematics. Also included are appropriate fuel use es- timates, contacts made in the field, and supporting calculations for heat recovery. The organization and presentation of the Kotzebue report is proposed to be similar to the previous reports noted above including color copies of photographs and figures. No right-of-way research or investigation is included. The proposed approach to the new Kotzebue waste heat report dictates that very little, if any information can be re-used from the existing Polarconsult report. All of the field work will be required and all of the production work will be new including figures, tables, and graphs. Our fee estimate does rep- resent some economy of scale based on our production of the Nome report and previous reports. One final note as to schedule: the time from Notice to Proceed to submission of final report is approximately 4 weeks plus rough draft report review time. If there is no rough draft submittal, the work could be completed in 4 weeks. Should you have any questions regarding the contents of this proposal or the attachments, please do not hesitate to call me.

Each project will require a separately executed Work Order and cost. Each project description identifies completion dates as to when the Authority requests that the work be accomplished. Each responding proposal must include a proposed completion date for cach of the two required submittals if quality products cannot be produced by the dates specified. The final submittals must be of high presentation quality including color copies of photographs, color copies of CAD drawings, and laser printer produced text. CAD drawings will use color to distinguish among primary loop, secondary loops, existing and new construction, and other separation that enhances the ease of reviewing the design. Legends indicating the use of colors will be provided on the drawings. Covers for the final submittal will be provided by the Authority as will AutoCAD files of the title blocks for the required CAD drawings. If existing maps are marked-up for inclusion in the report, high quality results are required. If the 8.5" x 11" format of CAD drawings does not produce legible drawings, 11"x 17" fold-outs are required. The initial submittal is to be of draft presentation quality with black and white products only. Submitted products are subject to rejection for quality of presentation as well as technical content. The users of the final products will include Authority staff, State and local government personnel, personnel of affected utilities, using facilities’ staff, and bond market consultants. The concept level designs and costing may be reviewed by an independent firm. Depending on the availability of funds and the results of the initial work, it is anticipated that some of the projects will result in RFP’s for work orders to complete final construction documents for summer 1990 construction. Each proposal will present the following items: 1. By major task and submittal, the discipline, man-hours proposed, and previously negotiated rate. 2. By major task and submittal, the names of personnel assigned. 3. By major task and submittal, identify the hours and rate for CAD workstation charges. 4. By major task and submittal, estimated expenses (to include weather contingencies for field investigations). 5. By submission, an estimate of the number of CAD drawings to be produced (initial submittal is to be black and white, final submittal to be in color - additional charges for color plotting effort is to be identified). 6. Proposed cost estimating firm and fee (in-house costing is not acceptable). It is required that one single kick-off meeting with Authority personnel be held prior to field investigations for all sites listed. The proposed costs must be allocated among the projects. It is required that one meeting be held with senior representatives of each utility. The proposed costs must be allocated among projects at sites serviced by the same utility. Telephone contact in lieu of a meeting is not acceptable. Right-of-way and easement assistance will be provided by the Authority - the consultant is required to collect platting information prior to a single meeting to be held at the Authority's offices at which time a review of the anticipated potential requirements will be discussed and guidance issued. The proposed costs must be allocated among the projects. Field investigations should be of sufficient depth to negate the future requirements of further field investigations for completion of the construction documents. The consultant must submit a single, simple graphic presentation of the anticipated overall schedule indicating work on major tasks by project. Concept Level Documents Waste Heat Systems Concept level documentation shall include as a minimum the following: Right-of-way/Easement Map(s) A map showing property boundaries that would be crossed by the proposed system and existing right-of-ways / cascments (markup of existing map(s) is allowed). Criteria Listing A list of all codes and regulations used in determining the system design. Distribution Piping and Pumping A brief description is required of the proposed distribution piping system (both primary and secondary loops) including material, insulation, pumping scheme, and connection procedures. Sketch(es) are to be included as appropriate. Heat Exchangers A brief description is required of the proposed heat exchangers including potential configuration, locations and sizing. Sketches are to be included as appropriate. Miscellaneous Systems A brief description of all supporting systems including controls, engine modifications, powerhouse modifications, etc. is required including sketch(es) as appropriate. User Requirements A brief description of modifications required to potential end user systems including sketches as appropriate. Technical Analysis A presentation of the assumptions made, data collected, and calculations performed is required to support the design approach taken. Cost Estimate Cost estimates are to be presented with unit costs by task, anticipated contract cost, project contingencies of 10%, SIOH as provided, and a total estimated project cost. Unless otherwise directed, construction contract costs will be estimated assuming publicly advertised bidding, summer construction, and "mini-Davis-Bacon” wage rates. Major system components are to have separately identified life estimates and yearly maintenance cost estimates. Estimates of yearly fuel costs displaced by each user facility are to be identified. FAILURE ANALYSIS A brief description of the major modes of failure is to be presented. Each of which must include as a minimum conccpt Icvel details of the following: 1. Description of failure. | 2. Effects on the continued operation of the power generation system. 3. Description of environmental impacts. 4. Required immediate action of the power house or facility operators to minimize short-term and long-term damage to the system. \ 5. Estimate the frequency (occurrences per year). 6. Estimate of down time (days/year). 7. Description and estimate of effort and material to return full service (tasks/year). 8. Effects of system life on frequency of occurrence. 9. Design decisions made to minimize failure rate and impacts. Assumptions to be made include: 1. On-site operators’ skills are that of a "care taker”. 2. Skilled PM is performed three times per year (Fall, Winter, Spring). 3. Weather delay in reaching site is one day (assuming winter failure). 4. Travel for emergency response or major repairs is via jet service to major community and charter from local carrier to site. 5. Skilled mechanics for emergency response or major repairs are mobilized from Anchorage, Fairbanks, or Juncau as appropriate. 2Feb90 jrb " Kotzebue Waste Heat System Concept Level Design Problem There is an identified opportunity for the installation of a waste heat recovery and distribution system in the community of Kotzebue. The intent of this work order is to provide the Authority with sufficient detail to erform an economic analysis and to prepare for the later development of construction documents. Tasks 1. Data Collection (Anchorage) Existing drawings and site maps and/or aerial photos are to be collected and reviewed prior to field investigation. A discussion with the Authority’s Rural Projects staff is required to be accomplished prior to field investigation. In addition, telephone discussions with Kotzebue Electric Association personnel is to be accomplished to collect construction and operating concerns of the Utility. 2. Data Collection (Field) A field trip is required with the consultant furnishing the services of a senior mechanical engineer. Field work is to include examination of the power houses, potential distribution routes, and the HVAC equipment of the facilities determined by the consultant and the Authority to be potential candidates for use of the proposed waste heat system. Historical fuel consumption data are to be collected from facility owners or operators as well as load data from the Utility. Corresponding heating fucl costs are to be collected as well. Coordination with the Utility, the City government, and the owners and operators of the potentially served facilities is to be accomplished prior to the field work. 3. Products Two products are required. The initial submittal is to be a letter quality report including as a minimum: field trip notes, contacts made, list and description of potential served facilities, tabular and graphical presentations of the historical or estimated heating fuel consumption, tabular presentations of corresponding fuel costs of each potential facility by month, tabular and graphical estimates of available waste heat by month (identifying heat required at the power house), and a map showing locations of the power house and the potential facilities to be served. A narrative description of the proposed system is to be included. Three copies of the report are to be submitted. Work on the second submittal is to commence after receipt of the Authority’s review comments. Review comments will be provided to the consultant within 2 working days after receipt of the report for incorporation into the final submittal. The primary purpose of this report is to judge to overall feasibility of the proposed system and to identify the facilities to be considered for connection. A meeting at the Anchorage offices of the Authority is to be held to review the findings of the report. The second submittal is to be a letter quality report with an executive summary of the investigation. It is to include one copy in 8.5 x 11 format of all drawings produced as well as color copies of appropriate photos. All drawings are to be provided in AutoCAD rell0 compatible drawing files (either sketches or to scale as appropriate). The report should summarize the investigation and present a concept level design of the recommended system including concept level specifications and construction cost estimates based on publicly advertised, sealed bid procurement using "mini-Davis-Bacon" wage rates. Six copies of the report are required (including one unbound copy for use as a reproducible master). Proposed construction bidding is to be assumed as occurring in April of 1990. The basic intent of this product is to present the recommended solution and its construction and operating cost estimates in suitable detail to allow for the follow-on development of an Authority produced economic analysis. Schedule It is required that the work be completed on or prior to 28Feb90. The initial report is to be submitted on or prior to L9Feb90. we - MEMORANDUM 1/29/70 To: Gary Smith From: Peter N. Hansen Wf Subject: Kotzebue District Heat Study. I have reviewed the study as submitted by Earle Ausman, and in general it appears that he knows what he is talking about. The language and the general appearence of the study could use a little improvement, especially if this study is to be used to "sell" ‘the project. In the following I will list some of the items, which in my opinion can be improved. is The table of contents is useful for someone, who is familiar with the study and simply needs to find a certain page. However, for someone who has not read the study, the table of contents provides little information in reference to the contents of the study. Example: Who only knows what can be found under IV,F "Media". Are we talking about the press? One obviously has to know about district heating systems using water or ethylene glycol to understand what “Media” refers to. Each section title should explain something about the section; an appropriate title could be “Discussion of heat transfer fluids". Ze Page 1, paragraph 3: lst line should read “in two buried, insulated steel pipes" 4th line: delete “set of" Din Page 1, last paragraph: Delete any reference to meat and fish drying and especially to greenhouses; regardless of reasons, such applications have been fiascos and some of them may still be remembered by someone in Juneau, in spite of the traditional annual “Reformat Memory", which seems to take place down there. Page 3, second paragraph: Re-write paragraph after “19 . There is mo need to document previous experience in this field by the author at this stage. Also, any technical information about Tanana is irrelevant here. S = Figure IV.A.2 Do not use balancing valves, use modulating thermostatic valves at this location. &.

Bulkow 76 Rural Systems gineer SUBJECT: Trip Report, Kotzebue DATE: February 26, 1990 PURPOSE On February 12 the City of Kotzebue passed a resolution requesting that the governor declare a state of disaster emergency with respect to Kotzebue’s frozen water and sewer systems. In the days following the cities of Kiana, Noorvik, Noatak, Ambler, Kobuk, and Shungnak passed similar resolutions. On February 15 Governor Steve Cowper appointed a Disaster Assistance Response Team to determine the scope of the situation and make recommendations for long-term solutions. Though not a member of this team I attended the team organizational meeting on February 21 where it was indicated that using waste heat to heat the city water was being considered as a possible long-term solution in some locations. I accompanied the response team to Kotzebue on February 22 to coordinate their efforts with our ongoing designs for waste heat recovery systems in Kotzebue, Noorvik, and Noatak. KOTZEBUE I left Anchorage on the morning of February 22 and travelled to Kotzebue via Alaska Airlines. I travelled together with Steve Weaver of PHS(Public Health Service) and Gary Eddy, a consultant hired by ADES(Alaska Department of Emergency Services) to head the response team. We were met at the Kotzebue airport by Mike Bird of ADES and were taken to the hotel to check in and have lunch. The four of us then proceeded to the Fire Training Center where we met with the City Manager, Mike Scott. One room of the Fire Training Center has been set up as a ‘war room’ to facilitate managing the ongoing repair work. Mike Scott briefed us on the situation. Approximately one third of the city was cut off from the water supply when one of the supply loops froze. About half of this supply main is made of four inch diameter PVC piping while the other half is made of six inch diameter PE piping. Work was proceeding well in restoring service to the six inch portion of the line. It is feared that much or all of the four inch portion of the line shall have to be replaced since PVC piping is likely to crack under these conditions. All the service loops connected to the frozen water main froze at the same time it did and a handful of service loops connected to the still operating ’KEA’ main loop froze as well. Mike Scott then took us to the water treatment plant. The water treatment plant has spaces for two boilers but only one is currently installed. The boiler installed is a 600 MBH unit and it was indicated that the majority of this capacity was used to heat the treatment plant and what was left was used to heat the city’s water. Steve Weaver and Mike Scott indicated that no heat was added to the city water until the one water loop was frozen. It is believed that if heat had not been added the ‘’KEA’ loop would have frozen as well, and that if heat had been added earlier the frozen loop would still be operating. A disconnected shell and tube type heat exchanger remains in the water treatment plant from a previous waste heat recovery system that was shut down for reasons that remain unclear. Steve Weaver suggested that if waste heat is reconnected to the water treatment plant it would be best to heat the untreated water entering the plant. Heating the untreated water would provide some freeze protection and improve the efficiency of the water treatment process. From the water treatment plant we were taken to a facility at the water source. This facility houses an emergency generator and two boilers. The emergency generator provides backup power to the water supply pumps. The boilers were originally installed to provide preheating of the water being supplied to the treatment plant. These boilers are very old and were disconnected from the water supply line some years ago. Mike Scott indicated that reconnecting these boilers to the water supply line was being considered but it was uncertain whether the boilers could be made operational again. Mike Scott then took us back to the Fire Training Center for further discussion of the situation. NORTHWEST ARCTIC BOROUGH On the morning of February 23 Gary Eddy, Mike Bird, Steve Weaver, Henry Ogar (PHS), and I met with representatives of the Northwest Arctic Borough. The Borough was represented by Mayor Chuck Greene, Dennis Chipleman, Luke Sampson, and the mayor’s assistant. The mayor stated that he felt that the problems in the villages had be caused by poor insulation, operator errors, and poor system designs. Mr. Greene also stated that the money requested to date was their estimate of the cost of repairs and did not include system alterations to provide long-term solutions. A number of things were then discussed including: coordination of Borough input into the Response Team report, coordination of the Response Team visit to the Borough villages affected, the possibility of a Borough-wide water & sewer utility, the overexpansion of many of the village systems over the years far beyond the intent of the original system designs, and some particulars of the problems of the system in Noatak. About halfway through the meeting Dan Coffey, the Northwest Arctic School District maintenance supervisor, joined us. He stated that the waste heat system in Shungnak has not been operating since early December yet the School District continues to be billed for it. He was not sure what the particulars of the problem were but said he would look into it and give me a call within a week. I told him that if the problem was something simple like a burned out pump that perhaps we could just send him a replacement pump for his maintenance crew to install. Mr. Coffey also requested that I look into the possibility of connecting the school in Deering to the waste heat recovery system there. KOTZEBUE ELECTRIC ASSOCIATION From the Borough meeting I went to the Kotzebue power plant and met with the general manager, Brad Reeve. Mr. Reeve gave me a tour of the plant and then we returned to his office where we met with one of the operators, Steve Apgar. KEA has a long history of providing waste heat to the city water off and on over the years. Originally the ’KEA loop’ water main was simply run through the power plant and heated. Eventually three stack boilers, a shell and tube type heat exchanger, and a four inch diameter piping loop to the water treatment plant were installed. This equipment remains in place. It is believed that two to the stack boilers could again be made operational but since the buried loop to the water treatment plant was not drained when the city disconnected from it this loop is probably not usable. KEA is in the process of connecting all its generator engines to a single header and this shall likely be completed this summer. Waste heat is already used to preheat the engines, heat the power plant, and heat one of the two fuel tanks. The utility is very interested ina district heating system and wishes to operate and maintain the system. The KEA engineer, Glenn Pommeroy, has reviewed the concept design done for us by Polarconsult and Brad Reeve shall provide us with a copy of his comments once they are finalized. Brad Reeve agreed to let us contact Glenn Pommeroy directly and suggested that we have Fryer/Pressley contact Mr. Pommeroy directly for the information they shall need to produce a more thorough concept design. A good temporary means of aiding the city water system would be to connect he ‘KEA loop’ water main (which runs next to the plant) to the existing waste heat recovery equipment within the plant. While we were discussing this the mayor of Kotzebue called and agreed that the city would like to do this. After this meeting I checked in with the Response Team and then took the 4:35 p.m. Alaska Airlines flight back to Anchorage.
