INTRODUCTION INTRODUCTION This report contains preliminary technology profiles and energy require- ments forecasts that will be utilized as part of the Reconnaissance Study of Energy Requirements and Energy Alternatives for Kodiak Island Villages and Sand Point and King Cove. The report also contains minutes of public meetings held in each of the communities last October. This information is preliminary, is subject to change, and as such should be utilized appropriately. Final information will be contained in our draft final report to be issued 31 January 1981. Because the report is primarily for the purpose of allowing Alaska Power Authority review of cost and performance information, charts, diagrams, backup calculations, and technology discussions are not included. These materials will be included in the final draft. 2.

TECHNOLOGY PROFILES: HYDROELECTRIC GENERATION 10. TECHNOLOGY PROFILE SUMMARY Resource/Village: Hydropower-Humbolt Creek/Sand Point General Description: The stream serves as City water supply. Hydropower development will require reconstruction of intake and possibly pump sta- tion. Raise road embankment to elevation 50 feet NGVD. Assume average tailwater elevation is 10 feet NGVD. This will require some excavation in the channel below the existing road. The creek supports salmon but the salmon cause a water quality problem. Therefore do not provide fish passage at new embankment. The existing road embankment should probably be replaced because the quality of its construction is unknown. The embankment cannot be made higher than elevation 50 because it would create a large very shallow lake with water quality and freezing problems. Present lake level is 33 feet NGVD with a surface area of about 3 acres (estimated storage 15 acre-feet). Raising dam to 50 feet would probably give a total storage of about 100 acre-feet. Resource Location: 0.1 mile above mouth of Humbolt Creek Renewable or Nonrenewable: Renewable 11.

Environmental Impacts: Known spawning area for coho salmon. Existing gravel fill dam at proposed site currently blocks passage of salmon up- stream. Coho salmon below damsite could be adversely affected by stream- flow flucuations and siltation caused by project construction and opera- tion. Seismically induced structure failure could cause risk to life and property in Sand Point harbor area. Institutional/Social/Land Use Characteristics: Assessment incomplete Health and Safety Impacts: Assessment incomplete 14, TECHNOLOGY PROFILE SUMMARY Resource/Village: Hydropower—Delta Creek/King Cove General Description: Earthfill embankment approximately 100 feet high. Penstock from the reservoir downstream to powerhouse develops about 300 feet of head. mall earthfill diversion dam. Storage potential looks limited. Map scale insufficient to compute storage available. Spillway can be located at the right abutment. A channel can be excavated into a relatively flat bench on the right. Spillway will probably need to be lined to prevent erosion. Run the penstock from the diversion dam down- stream along the bench on the right side to a powerhouse in the vicinity of the airstrip.

TECHNOLOGY PROFILE SUMMARY Resource/Village: Hydropower-Camp Bay Creek/Akhiok General Description: A low concrete diversion dam diverts water from Camp Bay Creek into a penstock that runs parallel to the creek to a powerhouse located near the mouth of the creek. Construct a low con- crete diversion dam with an overflow spillway. An alternative could be a lake tap at the unnamed lake on the headwaters of the Camp Bay Creek. However, the diversion is probably cheaper, and locating it downstream from the lake gives more drainage area and therefore a more dependable flow. Penstock parallels the creek to a powerhouse near the creek mouth. Powerhouse located so that tailwater elevation is about 50 feet NGVD.

TECHNOLOGY PROFILES: 49, WOOD AND PEAT BURNING TECHNOLOGY PROFILE SUMMARY Resource/Village: Wood burning for central power generation/Larsen Bay General Description: Locally available wood would be collected and burned in a central boiler to produce moderate pressure (250 psi) steam. The steam would drive a turbine/generator unit producing approximately 100 kW average electric output. Low-pressure steam exiting the turbine would be condensed for reuse in the boiler. Wood stoves in individual housing units and other structures would con- tribute to space heating load. Cut wood would be made available to vil- lage residents at the central generating facility site. Resource Location: Wood resource is locally available. Initial har- vesting would be close to the village. As harvesting proceeds, roads would be extended to outlying areas as necessary. Renewable or Nonrenewable: Renewable Resource Characteristics: Resource components are: (1) wood gathering equipment, (2) mobile wood chipping machine, (3) wood chip storage and transportation device, (4) power generation facility building and wood chip storage area, (5) boiler unit, (6) turbine/generator unit, 50. (7) miscellaneous piping and controls, (8) road construction equipment, (9) boiler feed chip handling equipment, and (10) emission control equipment. Resource Integration: No special requirements (Note: Larsen Bay cur- rently does not have a central electric generating or distribution system.) Energy Production: 100 kW average; 876,000 kWh/year Input Energy (Fuel) Characteristics: The electric generating system would require approximately 7.7 tons of bone-dry wood per day, or 2,800 tons per year. These requirements are based on an assumed heating value of 8,000 Btu per pound dry wood. Resource/Input Energy Reliability: The density of available wood product (tons/acre) is uncertain. Assuming wood availability is 10 tons/acre as found in the Bonaza Creek Experimental Project Stand, approximately 280 acres are required to provide the necessary wood product each year. The rate of regeneration of this biomass would be sufficiently slow so that an exceptionally large area of land would be required for a truly renew- able system. Resource Cost (December 1980 Price Levels): See attachment. Operating/ maintenance cost = $325,000/year. 51. Maintenance Requirements: The boiler/turbine generator unit would be monitored continuously by a single plant operator. One highly skilled maintenance person would be required part time. Wood chip collection process and road construction process would require a four-person crew operating 8 hours a day. Resource Development Schedule: Design, 6 months; construction, 12 months; startup 3 months Environmental Impacts: Significant environmental impacts due to boiler discharge stack emissions, boiler residue disposal, and problems caused by biomass removal from forested areas. Stack emissions can be mitigated somewhat via air pollution control equipment. Severe terrestrial and wildlife impacts due to disruption of forest habitat, noise impacts, soil erosion, road construction impacts, and reforestation programs. Assessment incomplete at this time. Institutional/Social/Land Use Characteristics: Limited land available for wood resource harvesting. Assessment incomplete at this time. Health and Safety Impacts: No major impacts 52.

Resource Integration: No special requirements Energy Production: 100 kW average; 876,000 kWh/year Input Energy (Fuel) Characteristics: The electric generating system would require approximately 7.7 tons of bone-dry wood per day, or 2,800 tons per year. These requirements are based on an assumed heating value of 8,000 Btu per pound dry wood. Resource/Input Energy Reliability: The density of available wood product (tons/acre) is uncertain. Assuming wood availability is 15 tons/acre as found in Delta Clearing Project, approximately 190 acres are required to provide the necessary wood product each year. The rate of regeneration of this biomass would be sufficiently slow so that an exceptionally large area of land would be required for a truly renewable system. Total acre- age for Spruce Island is approximately 10,000 acres, therefore severely restricting wood product available. Resource Cost (December 1980 Price Levels): See attachment. Operating/ maintenance = $325,000/year Maintenance Requirements: The boiler/turbine generator unit would be monitored continuously by a single plant operator. One highly skilled maintenance person would be required part time. Wood chip collection process and road construction process would require a four-person crew operating 8 hours a day. 54. Resource Development Schedule: Design, 6 months; construction, 12 months; startup, 3 months Environmental Impacts: Significant environmental impacts due to boiler discharge stack emissions, boiler residue disposal, and problems caused by biomass removal from forested areas. Stack emissions can be miti- gated somewhat via air pollution control equipment. Severe terrestrial and wildlife impacts due to disruption of forest habitat, noise impacts, soil erosion, road construction impacts, and reforestation programs. Assessment incomplete at this time.

Health and Safety Impacts: No major impacts 55% TECHNOLOGY PROFILE SUMMARY Resource/Village: Decentralized wood burning for residential space heating/Larsen Bay and Ouzinkie General Description: Locally available wood would be cut, collected, and transported to a central site in the village for sale and distribu- tion to village residents. Wood burning stoves would be installed in homes currently without such devices to provide space heating. Resource Location: Larsen Bay and Ouzinkie Renewable or Nonrenewable: Renewable Resource Characteristics: (1) Wood cutting, sizing, and transporting equipment, (2) road construction equipment, (3) wood stoves for individ- ual housing units (assumed 30 stoves installed) Resource Integration: N/A Energy Production: For 30 residential units, energy production (older house/no insulation) = 288 million Btu/yr, energy production (HUD house) = 79 million Btu/yr Input Energy (Fuel) Characteristics: N/A 56.

Institutional/Social/Land Use Characteristics: No major considerations; assessment incomplete at this time. Health and Safety Impacts: No major impacts 7s TECHNOLOGY PROFILE SUMMARY Resource/Village: Peat burning for central power generation/all villages General Description: Locally available peat would be collected and de- watered to approximately 20,percent solids content by mass using a "V" press at the collection site. The material would be transported to the generation site, where it would be compressed to form briquettes at ap- proximately 50-percent solids content by mass. The briquettes would be stored in silos to further air dry. When dried to the desired level, the briquettes would be burned in a boiler to provide moderate-pressure (250 psi) steam. The steam will drive a turbine/generator unit producing approximately 100 kW average electric output. The low-pressure steam exiting the turbine will be condensed for reuse in the boiler. Peat burning wood stoves in individual housing units and other struc- tures would contribute to the space heating load. Peat briquettes could be made available to village residents at the central power generating facility site. Resource Location: A medium quality/heat content peat resource is locally available to all villages. Initial harvesting would be close to the village with later harvesting in outlying areas as needed. Renewable or Nonrenewable: Renewable 58. Resource Characteristics: Resource components are (1) peat cutting and gathering equipment, (2) mobile "V" belt press, (3) peat field storage and transportation device, (4) compactor device, (5) power generation facility building and peat storage area (silos), (6) boiler unit, (7) turbine/generator unit, (8) miscellaneous piping and controls, (9) road construction equipment, (10) briquette handling equipment, (11) emission control equipment. Resource Integration: No special requirements. (Note: Larsen Bay currently does not have a central electric generating or distribution system.) Energy Production: 100 kW average; 876,000 kWh/year Input Energy (Fuel) Characteristics: The energy available from peat depends on the moisture content of the material. A typical heat content of approximately 4,000 Btu per pound dry peat will require approximately 15 dry tons of peat material per day to generate at the stated output levels (5,500 tons per year). Resource/Input Energy Reliability: The Peat Resource Estimation in Alaska prepared by Northern Technical Services dated October 1980 did not test the local areas under study. The study's description of the Kodiak Island area is as follows: "Four samples were obtained from sites on the northeastern side of Kodiak Island. Because of difficult access to the mountainous interior of the island, all sample sites were 59. located in the coastal areas. Kodiak Island is downwind from the volcanically active Aleutian Chain and was substantially affected by both ash fall and tsunami activity after the Mt. Katmai eruption in 1912. Field observations indicated volcanic ash deposits throughout the peat strata. Similarly, chemical analysis of the Kodiak samples show ash content of 18 to 49 percent. From the data taken, no positive correla- tion can be made of ash content with depth. Mineral soil was found at all sites within 7 feet of the ground surface." Substantial ash content levels would be detrimental and possibly pro- hibitive to boiler operation. Resource Cost (December 1980 Price Levels): See attachment. Operating/ maintenance $325,000/year Maintenance Requirements: The boiler/turbine generator unit would be monitored continuously by a single plant operator. One highly skilled maintenance person would be required part time. Peat collection process and road construction process would require a four-person crew operating 8 hours daily. Resource Development Schedule: Design, 6 months; construction, 12 months, startup, 3 months Environmental Impacts: Significant environmental impacts due to boiler discharge stack emissions, boiler residue disposal, and problems caused by peat removal from resource areas. Stack emissions can be mitigated somewhat via air pollution control equipment. Severe terrestrial and 60. wildlife impacts due to disruption of habitat, noise, soil erosion prob- lems, road construction, and replacement programs. Assessment incomplete at this time. Institutional/Social/Land Use Characteristics: Limited access and land available for peat resource harvesting; assessment incomplete at this time. Health and Safety Impacts: No major impacts 61.

TECHNOLOGY PROFILES: SOLAR ENERGY 72. TECHNOLOGY PROFILE SUMMARY Resource/Village: Active solar heating/all villages General Description: A liquid solar space and water heating system to be attached to individual housing or other building units. Flat plate collectors would be used to collect and transfer heat to a main storage tank through a glycol-to-water heat exchanger. Heat from the main stor- age tank is then transferred to the home space heating system and used to preheat domestic hot water. Resource Location: System is located with each unit (e.g., housing unit) that is to receive the heated water. Renewable or Nonrenewable: Renewable Resource Characteristics: Solar insolation data for the six villages under consideration are not readily available. The villages lie between approximately 55 and 60 degrees north latitude. Solar data are available for Annette (55.02 N) and Bethel (60.47 N), and were used to approximate conditions. However, the villages are exposed on the Alaskan Gulf and may be subject to different local weather conditions. Resource Integration: System linked to existing heating and domestic water systems. May be a problem for units that have stand-alone furnaces and hot water heaters. Jas Energy Production: Analysis was done for a combined space heating and water heating system assuming an 800-square-foot residential unit with average heat loss of 50 Btu/sq ft/hour. For a 500-square-foot collector system approximately 15 to 20 percent of the total heating requirements could be met by the active solar system. For a 1,500-square-foot collector system, approximately 45 to 50 percent of the total heating requirements could be met. ‘The solar equipment could provide approximately 30,000 Btu/year per square foot of collector area. Input Ener (Fuel) Characteristics: Average energy requirements for a P oY | typical residential unit for heating would consist of less than 30 percent solar input and greater than 70 percent backup source energy input. In addition, a nominal input of electricity would be required to run the fans and pumps. Resource/Input Energy Reliability: Relatively unreliable due to weather and solar insolation variability. Backup heating source required. Resource Cost (December 1980 Price Levels): See attachment. Operating/ Maintenance cost = $400/year Maintenance Requirements: Minimum maintenance requirements for system equipment that is indoors; however, moderate maintenance required for outdoor equipment. Expect that maintenance can be performed biannually by semi-skilled operator. 74.

System would consist of solar panels, lead- calcium storage batteries, matching control panel, charging regulator, and other required accessories. Resource Location: System to be located with each unit (e.g., housing unit) that is to receive the power produced. Renewable or Nonrenewable: Renewable Resource Characteristics: Solar insolation data for the six villages under consideration are not readily available. The villages lie between approximately 55 and 60 degrees north latitude. Solar data are available for Annette (55.02 N) and Bethel (60.47 N), and were used to approximate conditions. However, the villages are exposed on the Alaskan Gulf and may be subject to different local weather conditions. Resource Integration: System to be tied directly to the equipment that will be using the power. No tie to existing village power systems. 76.

TECHNOLOGY PROFILES: ENERGY CONSERVATION 79: TECHNOLOGY PROFILE SUMMARY Resource/Village: Energy conservation for older housing stock/all vil- lages except Old Harbor General Description: ° Insulate ceilings with R-30 batt insulation ° Wrap the outside of the houses with rigid polystyrene or poly- urethane board covered with prefinished T-1-11 plywood, paint inside walls with a water-vapor-resistant paint ° Insulate the floor with R-11 batt insulation and sheath the floor joists with gypsum board ° Install storm windows Resource Location: Older housing stock in all villages except Old Harbor. Assumed little or no insulation currently existing in these housing units. Renewable or Nonrenewable: N/A Resource Characteristics: Insulating the houses will reduce heating fuel requirements to one-fourth current requirements. More than half 80. the savings results from installation of ceiling insulation. The next most cost-effective measure is insulating the floor, then wrapping the walls, and finally installing storm windows. Resource Integration: The ceiling and floor insulation will not be notice- able. Wall insulation technique will make the residences appear like newer housing stock. Energy Production: Annual energy saving per older house due to reduc- tions in transmission and infiltration heat loss is estimated at 213.8 million Btu (approximatly 1,485 gallons #2 heating oil). Input Energy (Fuel) Characteristics: None. Resource/Input Energy Reliability: Insulation performance over time is a major unknown. Resistance values will decrease over time as the insu- lation retains moisture, but the extent of degradation is not predictable. Vapor barriers should be used where possible. With polyurethane board, moisture migration is not a problem as far as degradation of insulation is concerned. But the impermeability to mois- ture can create another problem--trapping moisture and creating an environ- ment for dry rot of the current siding. To help alleviate this possibility, it is suggested that the inside surfaces of exterior walls be painted with a moisture-resistant paint. 81. Resource Cost (December 1980 Price Levels): ° Insulating ceiling with R-30 batt insulation $1.50/sq ft ceiling area ° Insulating floor and installing sheathing $2.50/sq ft floor area ° Wrapping outside walls with polyurethane $4.50/sq ft and T-1-11 wall area ° Installing storm windows $33.00/sq ft window area Maintenance Requirements: None, if properly installed Resource Development Schedule: Immediate Environmental Impacts: No major adverse impacts;, possible beneficial impact resulting from reduction in emissions from existing oil-fired furnaces Institutional/Social/Land Use Characteristics: No major considerations Health and Safety Impacts: No major impacts 82. TECHNOLOGY PROFILE SUMMARY Resource/Village: Energy conservation-flame retention burner installa- tion/Old Harbor and Sand Point General Description: Replace standard oil burners on forced-air furnaces in newer HUD houses with flame retention burners. Resource Location: Forced-air oil furnaces equipped with standard gun- type oil burners can be retrofitted with fuel-efficient flame retention burners. Forty-five HUD homes in Old Harbor are equipped with this type of gun-type burners. Ome such conversion has been made in Sand Point. Renewable or Nonrenewable: N/A Resource Characteristics: Furnaces equipped with the standard gun burner have an average efficiency rating of 73 percent. Furnaces equipped with the flame retention burner have an average efficiency rating of 85 percent. A further reduction in oil use can be realized by downsizing the furnace from the current 50,000 Btu per hour rating. Resource Integration: N/A Energy Production: Annual energy saving per installation due to increased combustion efficiency is estimated at 33.8 million Btu (235 gallons No. 2 heating oil). 83.

TECHNOLOGY PROFILES NOT INCLUDED The following energy resource technologies were investigated and deter- mined to be clearly not worthy of further consideration due to the stated reason(s). Geothermal resource heating/King Cove Relatively low temperature resource located approximately 20 miles distance through mountainous terrain. Transmission costs too great to warrant further consideration. Hot water district heating systems/all villages Determined to be clearly infeasible due to large transmission dis- tances between individual housing units, incompatibility with existing heating devices, prohibitive maintenance requirements, requirement for backup heating source, and high cost of heating resource. Waste heat recovery - new city generating plant warehouse/King Cove No requirement to heat accompanying warehouse. Conservation - Schools and other large structures/all villages Determined to be clearly not deserving of further study due to the low potential for energy savings resulting from installation of conservation devices. In general, schools and other large struc- tures are recently constructed with adequate insulation, weather- proofing, and other conservation measures currently existing. 88. 11. SITE VISIT PUBLIC MEETING MINUTES 89. ALTERNATIVE ENERGY RECONNAISSANCE STUDY Public Meeting at Old Harbor October 23, 1980 Residents estimate that it requires three barrels of diesel per month to heat homes during the winter (2,000 gal./yr.). A population increase of 100 people has been projected for within the next ten years. All houses are currently occupied. The average household pays between $130 and $150 per month for electricity. This includes an average of two lightbulbs, refrigerator, television, and freezer at AVEC's rates of 39.5¢/kWh. Outages are common. There are no salmon in Ohiozik Creek. Tidal speed through Sitkalidak Passage is estimated at between four and five knots. This is the main traffic route for fishing vessels and other boats, however. Comments made on the location of domestic water supplies. At the pre sent, water is pumped up to storage tanks. Questions on why there isn't a gravity feed system. The village has a water treatment system. Some families burn driftwood rather than diesel for heat. It is estimated that there are two to three inches of insulation in the walls of the older homes. Most of the newer homes do not have vapor barriers. The windows are in bad shape in the older homes. One person at the meeting commented that "Anderson" windows with plastic work well. 90. Electricity is provided by AVEC. The school also utilizes electricity from the AVEC system. System outages occur at least two times per week. The existing school was completed in 1962. Request has been made to the Legislature for funds to construct a swimming pool. Comment by Mike Eunick of Port Lyons that Alaskan village residents typically use perhaps only 25 percent of the energy that they might use under more favorable circumstances. Rick Burns, mayor, estimates Old Harbor's household usage at 850 kWh's per month. In 1978 the Alaska Power Authority studied Old Harbor, Port Lions, and Larsen Bay for potential hydroelectric development demonstration projects. Conclusions were that Larsen Bay would get the project. However, nothing has happened. Old Harbor fishermen sell their catch to Columbia Ward's cannery at Alitak Bay. The River off of Three Saints Bay does not have salmon. They were killed many years ago by "bluestone" used to chase fish into fish traps. 91. Public Meeting at Larsen Bay October 22, 1980 CH2M HILL's project team was invited to attend the Tribal Council meeting at Larsen Bay and make a presentation. Comments pertaining to the energy reconnaissance project follow. It is estimated by Jack Wicks that family housing in Larsen Bay will double within the next two years. Individual homes or groups of two or three homes generate power from small "light" plants. These require approximately 4 to 4-1/2 gallons of diesel per day to operate. Electricity is usually generated only during the evening periods or when needed. With an average of 10 hours per day light plant use typical, electric fuel consumption is reported at about 137 gal./mo. This is about 7 kWh/gallon expected. The comment was made that Larsen Bay is looking for a centralized power system as a method to cut costs. An interim measure towards this idea is to construct a centralized distribution system (Larsen Bay suggested underground). Fuel costs $1.30 per gallon in Larsen Bay. Tom Peterson of Kodiak Area Native Association, representing Kodiak Island Housing Authority, discussed plans to add additional HUD-funded housing. During the next five years it is estimated that Larsen Bay may add as many as 15 to 20 new HUD houses. 92. It is estimated that population in Larsen Bay will increase 25 percent during the next five years (KANA). Public Health Service publishes a five-year growth forecast. It was suggested that one reason for future growth at Larsen Bay will be due to the new high school which began operating in the fall of 1980. Currently many other villages on Kodiak Island must send their kids to Kodiak High School for their junior and senior years. The possibility exists that families may move to Larsen Bay in order to be with their children who are attending the last two years of High School. The Retherford report on Humpy Creek, prepared for the Alaska Power Administration (January 1980), was discussed. Frank Peterson indicated the need for a pump system versus gravity flow system for the local water supply (PHS). Some houses in Larsen Bay still get their water from shallow wells. Art Panamaroff stated that PHS had brought an engineer into Larsen Bay--they may be constructing a water system by the fall of 1981. Contact Mike Dorsky, Indian Health Service, Anchorage. Jack Wick stated that there is a one square mile townsite at Larsen Bay. The village corporation owns an additional 70,000 acres, but a clause states that all uses of this area must be compatible with the Kodiak Island wildlife refuge (bear refuge). Jack Wick stated that the Tribal Council had looked at the possibilities of hydropower development in Humpy Creek five years ago and were favorably impressed. 93. In 1964 the earthquake caused the area at Larsen Bay to subside approx- imately 3.6 feet. The potential hydroelectric damsite is located above the village. The Tribal Council decided that the top priority in their revised OEDP plan will remain hydroelectric development for the village of Larsen Bay. 94, Public Meeting at Ouzinkie October 20, 1980 The Village of Ouzinkie has approximately 200 residents (1980) and 55 houses, 10 of which are not hooked into the existing electrical generating system. The village currently generates electricity for 15 hours per day, from 7:00 a.m. through 10:00 p.m. Typical appliances include freezers, refrigerators, and washing machines. A new school is being constructed. Once completed it will require additional generating capacity and will have its own system. Other large structures in the village include a warehouse and store. Gasoline consumption is insignificant since there are only three vehicles in the village and 25 to 30 three-wheelers. Gasoline is brought in by individuals in 55-gallon drums. A new electrical distribution system is being constructed, rates will be changed from a flat rate of $60 per month per household to metered rates. Six to seven houses have individual generators as a standby measure. Ouzinkie has financed, through the Kodiak Island Borough, purchase of a 150 kW generator through a small city block grant. Wind in Ouzinkie is not a predictable resource. Information on consumption of fuel for heating was provided. It was noted that wood stoves are being added to HUD houses. There are 23 HUD houses, with ten more planned for construction in 1981. 95. A winterization project to provide materials for home insulation was ini- tiated two years ago through Rural Alaska Community Action Program. There was some question, however, from residents as to the effectiveness of this program. Norm Smith, utility manager, commented on system waste caused by intermixing old and new electricity generating systems and by using flat rate assessments. Local concensus was that hydroelectric development would be desirable and preferable to diesel-powered generation. It was stated that the existing generating capacity (90 kW) is not suffi- cient to provide power through this winter. There is a landing strip planned for Ouzinkie; access is currently via float plane or boat. There are few salmon in Katmai Creek. The stream off Neva Cove does have salmon, however. There were some ideas presented on harnessing tidal power, including digging a channel across a 450-foot isthmus to harness the tides. Jack West mentioned the need to find ways to transport wood for heating to villages without the use of trucks (since there are only three trucks in the village). It appeared that wood heat would be more economical than diesel furnaces. 96. A previous proposal to sell waste heat from the village to the school was discussed. Gary Smith, facilities coordinator with the Kodiak Island Borough, needs to be contacted. There are five furnaces that will be operating in the new school building. Employment opportunities decreased in 1974-75, with the closing and then burning of the cannery at Ouzinkie. Fishermen now fish for Colum- bia Wards. A presentation was made to a group of students at the school in Ouzinkie. 97; Public Meeting at Sand Point October 15, 1980 The U.S. Corps of Engineers had an anometer at the harbor at Sand Point for a full year approximately five years ago. Pacific Pearl owns the village utility system. Concern was expressed about working with them, particularly if individuals began to establish their own wind generation systems. Edgar Smith suggested coal, which exists at Coal Harbor. Note that Tom Dobson (Edgar Smith's uncle) at King Cove used to have a windmill. Also, there used to be a windmill at Sand Point. Comment that Akutan operates its telephone system off of a waterwheel generating system. Ken Selby should be able to answer questions on plans to improve the source of the village's water supply and also any information on potential hydroelectric. Land is not available. Younger people are not able to acquire land to construct homes on, causing restriction in growth of the village. A plan requires utilities to be constructed before land can be sold. Therefore, Pacific Pearl has adopted a policy not to sell any land for residential development. 98. Dr. Wakefield owns land but will not sell. He is assumedly waiting for the planning and zoning issues to be resolved. There is controversy over 1200 acres of land claimed by both the village corporation and the City of Sand Point. The economic base of Sand Point is limited to a general store, fish pro- cessing plant which also sells fuel and fishery supplies, a small cafe, mobile welding service, school, and government. It was noted that there isn't even a repair garage for vehicles, which results in many late model trucks being junked relatively quickly. Comment that Sand Point used to be an did cod fishing and processing area. Note that in Akutan the Norwegian Fish Company is splitting and salting cod, which is picked up by freighters and shipped to Norway. Estimates are that a two-month salmon crew share may be between $75,000 and $120,000. However, it was also stated that few people in Sand Point actually hold a $30,000-per-year job. Comment that if land was made available population would double immediately. Some houses in the city have never had power since formal beginnings of the city 15 to 20 years ago. Some of these people have been residents of Sand Point for 40 to 50 years. Comment that a man in Unalaska constructed three windmills and that he is also a wind power dealer. S39: Public Meeting at King Cove October 16, 1980 An announcement of this public meeting was cut into the local news program. Don Baxter of Alaska Power Authority joined the CH2M HILL field team (Katie Eberhart, Steve Schulte, and Glen Dearth). A slide show and description of alternative energy possibilities was presented, followed by a question and answer period. Question: How much output would you expect from a wind machine? Answer: Boeing is providing a commercially available 2-1/2 MW wind machine. Question: AC or DC current? Answer: Either can be integrated into a system. Comment that there is little hope for solar development at King Cove (however, it was brought to our attention that in False Pass an individual is operating a solar and wind-powered living system). Comment that there are hot springs across the bay from Cold Bay. Question as to whether or not it would be possible to transport either hot water or electricity generated from this source to King Cove. 100. A Comment by Don Baxter that for geothermal to be economically feasible, rule of thumb that water must be at least 170°F. Comparison of this potential resource to Iceland and New Zealand geothermal energy which has been developed. Possibility that the transport costs may make this resource uneconomical as far as King Cove is concerned. Question as to whether EPA is evaluating the feasibility of wind generators in North Carolina. Comment by Schulte that relative feasibility of wind generation systems are based on the economics/cost of alternative sources of energy. Differences in wind power development in North Carolina versus Alaska were discussed. Don Baxter commented on trends in Alaska, particularly wind and tech- nology development. He also suggested that a base plan might be to continue diesel generation and utilize waste heat more extensively. No comments from residents regarding level of or possibilities for future growth in King Cove. 101. westerly winds. Driftwood 7-8 miles distant. Bear Refuge surrounds i Akhiok. J 103. Public Meeting at Akhiok October 24, 1980 Population: 100 year-round residents 30 summer (seasonal) residents Land Transportation: One truck Ten 3-wheelers Housing: 15 HUD homes 15 "older" homes Other Facilities: School Community Center Akhiok's population is stable. The village does not have a well-estab- lished economic base. A Columbia Wards cannery is located seven miles to the southwest at Alitak Bay. Land is difficult for individuals to acquire. The village corporation has selected lands outside the one-square-mile townsite. Barges deliver fuel oil to Akhiok or residents can obtain smaller amounts from the Columbia Wards cannery. Fuel oil sells for $66 per barrel. Oil is used in a typical five-bedroom HUD home for cooking (stove) and heating. Average use per house is 2,100 gallons annually; 4-5 barrels per month in winter and approximately two barrels per month in summer. 102. Tidal power does not appear to be a viable option. Steady prevailing
