In 2013, AEA provided funding to the City of Scammon Bay through the Renewable Energy Fund for initial planning and feasibility analysis of hydroelectric potential in the vicinity of the community. Under this previous grant, Scammon Bay partnered with ANTHC to carry out the study, which was performed as subcontract by Hatch Engineering. This initial study was completed in 2014 and identified the best locations for hydroelectricity development in Scammon Bay, which had a variety of creeks available for development of a small hydroelectric facility. The most promising site, located 12 miles to the west of town, located on Ekashluak creek was found to have a significant salmon population, and the community of Scammon Bay was not interested in developing the location. The small creek running through town, though smaller, was found to be an economic and low impact alternative opportunity to develop hydroelectric production to reduce diesel fuel consumption at the community AVEC power plant. A run-of-river hydroelectric project on the hillside creek running through the city of Scammon Bay has been found to be potentially beneficial based on existing knowledge and previous site assessments. In order to secure permitting and allow for a design that maximizes the potential of the resource, three years of stream gauging is required. Additionally, this project will fund survey and 35% design for the Scammon Bay hillside creek run of river hydroelectric project. The project has significant benefits beyond avoided diesel fuel use in power production. The community would improve and stabilize access to clean water for the water treatment plant, ensuring the health benefits of clean water for the community. 2.5 Scope of Work Provide a scope of work detailing the tasks to be performed under this funding request. This should include work paid for by grant funds and matching funds or performed as in-kind match. This phase of the project proposes to confirm the findings of the feasibility study and begin the design process. It is assumed that 3 years of stream gauging may be required by AEA although one year of gauging may be adequate for this small hydro facility. The project will also conduct field surveying required for land acquisition and preliminary and final designs. During this phase, basic integration with the diesel plant as well as any wind resources will be addressed. Additional consultation with stakeholders is also to be addressed. This consultation will include determination of ownership of any hydro facilities in the future, and any potential power sales arrangements. Barriers to the project could be the perceived or real loss of use of a portion of the stream from the powerhouse to the intake. However, the feasibility study found no fish impact in this area. Assuming conditions are confirmed, final design funding would be sought to include geotechnical work required for the water intake and final plans and specifications for the penstock and hydroelectric power plant. This project will utilize a run-of-river design. An existing access road to the community water storage tank can be used for construction and access to the intake. A diversion structure will be built that extends from flood water elevation down to bedrock across the creek channel utilizing local materials in the concrete fill that forms the foundation of the structure. Renewable Energy Fund Round IX Grant Application - Standard Form AEA 16012 Page 7 of 27 7/8/14 A coanda intake with shutoff and bypass gates, domestic supply priority weir, trash rack, and transition structure would be built at an elevation of 550 feet, sourcing water from a .73 square mile watershed. A 16” HDPE penstock would run from the intake, 4,300 feet to the powerhouse. A powerhouse would be built on the edge of town at an elevation of 70 feet. A static head of 480 feet, with hydraulic capacity of 6.0 cfs would provide the resource for electrical generation. The turbine and generator package would be a custom dual nozzle pelton turbine, induction generator, switch gear, control panels, hydraulic power unit, turbine inlet valve, and structural steel equipment mounting frames. Optimum installed capacity for the project would be 188 kW. With a net efficiency of the turbine, generator set of 82%.

Renewable Energy Fund Round IX Grant Application - Standard Form AEA 16012 Page 14 of 27 7/8/14 SECTION 5 – TECHNICAL FEASIBILITY 5.1 Resource Availability Criteria: Stage 2-3.A: The renewable energy resource is available on a sustainable basis, and project permits and other authorizations can reasonably be obtained. 5.1.1 Proposed Energy Resource Describe the potential extent/amount of the energy resource that is available, including average resource availability on an annual basis. Describe the pros and cons of your proposed energy resource vs. other alternatives that may be available for the market to be served by your project. For pre-construction applications, describe the resource to the extent known. For design and permitting or construction projects, please provide feasibility documents, design documents, and permitting documents (if applicable) as attachments to this application. Based on a 2014 feasibility assessment by Hatch Engineering, an estimated 39,252 gallons of diesel fuel could be replaced by reducing demand on the City’s diesel power plant. Alternative energy resources in Scammon Bay include wind power and heat recovery off of existing diesel generators. Wind power feasibility studies are currently underway; Scammon Bay is shown to have a relatively steady availability of wind resources year round. It is possible that hydroelectric power and wind power could both be utilized by the community. Due to the seasonal fluctuations anticipated in hydroelectricity production, heat recovery will remain viable in providing heat to local facilities in the winter months. Hydro will never displace 100% of the electrical load, and the hydroelectric plant would experience its annual minimum production during the cold winter months when heat recovery is needed. 5.1.2 Permits Provide the following information as it may relate to permitting and how you intend to address outstanding permit issues. •List of applicable permits •Anticipated permitting timeline •Identify and describe potential barriers This project is expected to be jurisdictional with respect to Federal Energy Regulatory Commission (FERC) licensing, as Scammon Bay is located within the Yukon Delta National Wildlife Refuge. Transportation and utility systems are allowed within the refuge. This project anticipates a successful application for an exemption as opposed to a FERC license. The diversion structure would likely to be exempt from Alaska Department of Natural resource dam safety program as the impoundment would be very small. Permitting overall would be led by the ADNR water rights application requirements for demonstrating rights to access and establishing water use quantities. If during the course of completing the design and finalization of the project, it is found that additional permits will be needed, ANTHC will ensure that they will be obtained during the final design phase of the project. 5.2 Project Site Criteria: Stage 2-3.B: A site is available and suitable for the proposed energy system. Describe the availability of the site and its suitability for the proposed energy system. Identify potential land ownership issues, including whether site owners have agreed to the project or how you intend to approach land ownership and access issues. Renewable Energy Fund Round IX Grant Application - Standard Form AEA 16012 Page 15 of 27 7/8/14 The anticipated powerhouse and penstock location is on land owned by the Askinuk Native Corporation. The City and ANTHC will work with the corporation during the development phase of this project, to have the appropriate easement and access to the land site. 5.3 Project Risk Criteria: Stage 2-3.C: Project technical and environmental risks are reasonable. 5.3.1 Technical Risk Describe potential technical risks and how you would address them. Potential risks will be evaluated during this phase of the project, and little to no risks are anticipated during the proposed phase of the project. Stream gauging will allow engineers to confirm not only the resource and power potential, but also confirm information about the stream which might present risks to construction or operation of a small intake and pipeline. 5.3.2 Environmental Risk Explain whether the following environmental and land use issues apply, and if so how they will be addressed: •Threatened or endangered species •Habitat issues •Wetlands and other protected areas •Archaeological and historical resources •Land development constraints •Telecommunications interference •Aviation considerations •Visual, aesthetics impacts •Identify and describe other potential barriers ANTHC will consider all potential environmental concerns associated with this project. ANTHC has extensive experience using the comprehensive Indian Health Service (IHS) environmental review procedures for conducting environmental analysis of all health and sanitation facilities projects in all stages of development, as outlined in the IHS environmental review manual issued in January 2007. 5.4 Existing and Proposed Energy System Criteria: Stage 2-3.D: The proposed energy system can reliably produce and deliver energy as planned. 5.4.1 Basic Configuration of Existing Energy System Describe the basic configuration of the existing energy system. Include information about the number, size, age, efficiency, and type of generation. The City of Scammon Bay currently utilizes diesel electric generation for 100% of its electrical needs. The Alaska Village Electrical Cooperative operates the power utility in Scammon Bay.

Renewable Energy Fund Round IX Grant Application - Standard Form AEA 16012 Page 17 of 27 7/8/14 5.4.2 Future Trends Describe the anticipated energy demand in the community over the life of the project. Between 2002 and 2014 kWh consumption in Scammon Bay increased from 1,032,754 to 1,722,360, an increase of about 70%. The current population in Scammon Bay is listed as 528 according to the State of Alaska Department of Community and Regional Affairs. 2010 US Census data listed the population in the community as 474, and the 2000 US Census listed the population as 465. Scammon Bay’s population has increased 11% in the last 15 years, and electrical consumption has increased ~70%. Electricity use is growing and so is the population. According to the attached feasibility study, electrical demand is forecast to increase from a modeled kWh consumption of 1,704,597 in 2014 to consumption of 4,498,112 by 2063. This would represent an increase in fuel usage from a modeled 121,897 gallons of fuel in 2014 to 296,759 gallons if diesel is the only source of electrical generation. 5.4.3 Impact on Rates Briefly explain what if any effect your project will have on electrical rates in the proposed benefit area over the life of the project. For PCE eligible communities, please describe the expected impact would be for both pre and post PCE. The project should bring down costs of delivered power, particularly to non PCE eligible commercial customers. Displacing fuel for diesel electrical generation will also benefit the PCE fund by reducing the necessity of the subsidy. 5.4.4 Proposed System Design Provide the following information for the proposed renewable energy system: •A description of renewable energy technology specific to project location •Optimum installed capacity •Anticipated capacity factor •Anticipated annual generation •Anticipated barriers •Integration plan •Delivery methods This phase of the project proposes to confirm the findings of the feasibility study and begin the design process. It is assumed that 3 years of stream gauging may be required by AEA although one year of gauging may be adequate for this small hydro facility. The project will also conduct field surveying required for land acquisition and preliminary and final designs. During this phase, basic integration with the diesel plant as well as any wind resources will be addressed. Additional consultation with stakeholders is also to be addressed. This consultation will include determination Renewable Energy Fund Round IX Grant Application - Standard Form AEA 16012 Page 18 of 27 7/8/14 of ownership of any hydro facilities in the future, and any potential power sales arrangements. Barriers to the project could be the perceived or real loss of use of a portion of the stream from the powerhouse to the intake. However, the feasibility study found no fish impact in this area. Assuming conditions are confirmed, final design funding would be sought to include geotechnical work required for the water intake and final plans and specifications for the penstock and hydroelectric power plant. This project will utilize a run-of-river design. An existing access road to the community water storage tank can be used for construction and access to the intake. A diversion structure will be built that extends from flood water elevation down to bedrock across the creek channel utilizing local materials in the concrete fill that forms the foundation of the structure. A coanda intake with shutoff and bypass gates, domestic supply priority weir, trash rack, and transition structure would be built at an elevation of 550 feet, sourcing water from a .73 square mile watershed. A 16” HDPE penstock would run from the intake, 4,300 feet to the powerhouse. A powerhouse would be built on the edge of town at an elevation of 70 feet. A static head of 480 feet, with hydraulic capacity of 6.0 cfs would provide the resource for electrical generation. The turbine and generator package would be a custom dual nozzle pelton turbine, induction generator, switch gear, control panels, hydraulic power unit, turbine inlet valve, and structural steel equipment mounting frames. Optimum installed capacity for the project would be 188 kW. With a net efficiency of the turbine, generator set of 82%.

Renewable Energy Fund Round IX Grant Application - Standard Form AEA 16012 Page 20 of 27 7/8/14 SECTION 6 – ECONOMIC FEASIBILITY AND BENEFITS 6.1 Economic Feasibility Criteria: Stage 2-4.A: The project is shown to be economically feasible (net positive savings in fuel, operation and maintenance, and capital costs over the life of the proposed project). 6.1.1 Economic Benefit Explain the economic benefits of your project. Include direct cost savings, and how the people of Alaska will benefit from the project. The benefits information should include the following: •Anticipated annual and lifetime fuel displacement (gallons and dollars) •Anticipated annual and lifetime revenue (based on i.e. a Proposed Power Purchase Agreement price, RCA tariff, or cost based rate) •Additional incentives (i.e. tax credits) •Additional revenue streams (i.e. green tag sales or other renewable energy subsidies or programs that might be available) The economic model used by AEA is available at http://www.akenergyauthority.org/Programs/Renewable-Energy-Fund/Rounds#round9. This economic model may be used by applicants but is not required. The final benefit/cost ratio used will be derived from the AEA model to ensure a level playing field for all applicants. If used, please submit the model with the application. The annual projected diesel fuel to be displaced is estimated at 39,252 gallons. At the current rate paid for fuel of $2.87, this amounts to an annual savings of $ 112,653 Potential lifetime fuel displacement is 98,130,000 gallons of fuel oil over the fifty-year lifespan. 6.1.2 Power Purchase/Sale The power purchase/sale information should include the following: •Identification of potential power buyer(s)/customer(s) •Potential power purchase/sales price - at a minimum indicate a price range •Proposed rate of return from grant-funded project Identify the potential power buyer(s)/customer(s) and anticipated power purchase/sales price range. Indicate the proposed rate of return from the grant-funded project. Ownership and power purchase from this project will be determined once further research and feasibility is performed on the hillside creek in Scammon Bay. 6.1.3 Public Benefit for Projects with Private Sector Sales For projects that include sales of power to private sector businesses (sawmills, cruise ships, mines, etc.), please provide a brief description of the direct and indirect public benefits derived from the project as well as the private sector benefits and complete the table below. See section 1.6 in the Request for Applications for more information. The potential additional benefits to private sector businesses will be evaluated more closely at the final design stage of this project. Renewable energy resource availability (kWh per month) Renewable Energy Fund Round IX Grant Application - Standard Form AEA 16012 Page 21 of 27 7/8/14 Estimated sales (kWh) Revenue for displacing diesel generation for use at private sector businesses ($) Estimated sales (kWh) Revenue for displacing diesel generation for use by the Alaskan public ($) 6.2 Financing Plan Criteria: Stage 2-4.B: The project has an adequate financing plan for completion of the grant- funded phase and has considered options for financing subsequent phases of the project. 6.2.1 Additional Funds Identify the source and amount of all additional funds needed to complete the work in the phase(s) for which REF funding is being applied in this application. Indicate whether these funds are secured or pending future approvals. Describe the impact, if any, that the timing of additional funds would have on the ability to proceed with the grant. 6.2.2 Financing opportunities/limitations If the proposed project includes final design or construction phases, what are your opportunities and/or limitations to fund this project with a loan, bonds, or other financing options? Limited funding opportunities exist for feasibility and conceptual design. The Renewable Energy Fund is one of the only opportunities to complete this effort to solidify Project Development and advance the project to an appropriate level of readiness to seek design/construction funding from other sources. 6.2.3 Cost Overruns Describe the plan to cover potential cost increases or shortfalls in funding. If potential cost overruns are identified at this stage of the project, cost estimates will be adjusted for future applications. 6.2.4 Subsequent Phases If subsequent phases are required beyond the phases being applied for in this application, describe the anticipated sources of funding and the likelihood of receipt of those funds. Final Design and Construction funding, if the project is proven feasible, will be sought from a variety of sources inclouding the State of Alaska Renewable Energy Fund, Power Production Loan Fund, grant/loan programs with USDA Rural Development, Department of Energy, and other sources will be sought to complete the project. 6.3 Other Public Benefit Criteria: Stage 3-4.C: Other benefits to the Alaska public are demonstrated. Avoided costs alone will not be presumed to be in the best interest of the public. Renewable Energy Fund Round IX Grant Application - Standard Form AEA 16012 Page 22 of 27 7/8/14 Describe the non-economic public benefits to Alaskans over the lifetime of the project. For the purpose of evaluating this criterion, public benefits are those benefits that would be considered unique to a given project and not generic to any renewable resource. For example, decreased greenhouse gas emission, stable pricing of fuel source, won’t be considered under this category. Some examples of other public benefits include: •The project will result in developing infrastructure (roads, trails, pipes, power lines, etc.) that can be used for other purposes •The project will result in a direct long-term increase in jobs (operating, supplying fuel, etc.) •The project will solve other problems for the community (waste disposal, food security, etc.) •The project will generate useful information that could be used by the public in other parts of the state •The project will promote or sustain long-term commercial economic development for the community This project will improve access to clean water for the community members of Scammon Bay. Scammon Bay’s existing water intake suffers from inconsistencies, a higher quality; higher flow rate intake would ensure clean water is available for residents year round. The benefits of clean water to public health are dramatic, and include reduce risk of infectious diseases and respiratory diseases. This project will improve the available information on operations of small hydroelectric projects in Arctic and subarctic conditions around the state, particularly in Western Alaska. Hydroelectric power is not widely generated in arctic and subarctic conditions such as those experienced in Scammon Bay. Lower cost of electricity can be widely beneficial to the community of Scammon Bay, especially as the community looks to develop their local fishing industry. Renewable Energy Fund Round IX Grant Application - Standard Form AEA 16012 Page 23 of 27 7/8/14 SECTION 7 – SUSTAINABILITY Describe your plan for operating the completed project so that it will be sustainable throughout its economic life. Include at a minimum: •Capability of the Applicant to demonstrate the capacity, both administratively and financially, to provide for the long-term operation and maintenance of the proposed project •Is the Applicant current on all loans and required reporting to state and federal agencies? •Likelihood of the resource being available over the life of the project •Likelihood of a sufficient market for energy produced over the life of the project City employees will conduct periodic maintenance such as cleaning intake screens, monitoring water levels and production numbers, and troubleshooting reported problems. Specialized contractors will be engaged when specialty work is required on the actual turbine. Maintenance of project-constructed infrastructure will be financed out of electrical rate collections from existing and future customers in Scammon Bay. Rates should eventually decrease from the increased hydroelectric production. Integration of existing diesel generation will need to be appropriately controlled to ensure proper switch gear operation and to minimize power distribution disruptions. This project is proposed specifically to identify concerns with the availability of the resource over the life of the project. Our changing climate is changing rainfall and stream flows all over the world, and it will be crucial to have accurate stream gauging data to ensure this project is accurately designed to fulfill its potential. Scammon Bay is a growing community with growing electrical needs. The demand for more electricity is anticipated to continue growing, and the market can handle all hydroelectric power produced.

Introduction 1.1 Project Background Currently, Scammon Bay generates electricity entirely through diesel fuelled generators operated by the Alaska Village Electric Cooperative (AVEC). The high cost of diesel fuel in Scammon Bay and the challenges of operating in remote Alaska make electrical generation expensive. The current electrical rate in Scammon Bay is $0.651/kwh. The community is highly motivated to identify alternative forms of electrical generation in order to reduce rates, and reduce the community’s dependence on diesel fuel. 1.2 Scope of Project The general scope of work for this project is review of previous studies, perform aquatic investigations, prepare conceptual designs and cost estimates for viable hydroelectric alternatives, and update the economics for potential development. The project includes analysis and conceptual designs for the most beneficial and feasible hydroelectric project(s). 1.3 Previous Studies 1.3.1 Hillside Creek Previous investigations for a hydro project on the creek that runs through Scammon Bay were documented in reports from 1979 to 1985. A development scheme was initially recommended with a capacity of 100 kW. After further evaluation it was not recommended. Annual electrical demand was 426 MWh compared with present day demand of 1,700 MWh. The following are the most relevant studies: United States Army Corps of Engineers (USACE 1982), "Scammon Bay, Alaska: Small Hydropower Interim Feasibility Study and Environmental Assessment", March 1982. Average stream flow estimated to be 2.5 cfs. Recommended 100 kW project with a benefit to cost (B/C) ratio of 1.2. Wind power could complement the system. Alaska Power Authority, "Financial Analysis for Scammon Bay Hydroelectric Project", DOWL Engineers, September 1984. Approximate physical configuration: Intake elevation 600 feet Powerhouse elevation 112 feet Penstock diameter 12 inches Penstock length 3,500 feet Power 100 kW Annual energy 410 MWh Alaska Power Authority (APA 1985), Findings and Recommendations Scammon Bay, December 5, 1985. 1 Residential customer rate as reported by AVEC in May 15, 2014 filing with RCA includes all costs for service. Alaska Native Tribal Health Consortium - Hydroelectric Feasibility Study, Scammon Bay, AK Hillside Creek Project Final Report September 19, 2014 Rev. 0 Page 2 © Hatch 2014 All rights reserved, including all rights relating to the use of this document or its contents. This study revised the hydrology estimates and concluded with no recommended alternatives to diesel generation. Demand was 426 MWh in 1984. B/C ratio decreased to 0.74. 1.3.2 Ekashluak Creek A development scheme for Ekashluak Creek was investigated by Polarconsult with the findings presented in a report in 2003. Alaska Village Electric Cooperative (AVEC 2003), Scammon Bay Feasibility Study, Final Report, March 7, 2003. Report prepared by Polarconsult for development scheme on Ekashluak Creek. Report did not find a feasible project at that location. B/C ratio determined to be 0.5 due to the long transmission line. 2. Environmental Considerations 2.1 Community Description The following information was obtained from the Department of Commerce, Community, and Economic Development, the Division of Community and Regional Affairs, the Community Information for Scammon Bay (DCRA 2014). General Overview 2nd Class City in the Wade Hampton Census Area Current Population 518 (2013 DCCED Certified Estimate) Geography and Climate Location Scammon Bay is on the south bank of the Kun River, one mile from the Bering Sea. It lies to the north of the 2,300-foot Askinuk Mountains on the Yukon-Kuskokwim Delta. Climate The area's climate is maritime. Temperatures range between -25 and 79 °F. Annual precipitation averages 14 inches, with 65 inches of snowfall. Severe easterly winds during the fall and winter limit accessibility. The Bering Sea is ice-free from mid-June through October. Latitude 61.8428 Longitude -165.5817 History and Culture It was known in Eskimo as "Maraayaq," and its residents were called "Maraayarmiut." The nearby bay was named after Capt. Charles Scammon, who served as the marine chief of the Western Union Telegraph Expedition from 1856 to 67. The name came into use when the Scammon Bay Post Office was established in 1951. The city government was incorporated in 1967. Scammon Bay is a Yup'ik Eskimo community that relies on fishing and subsistence activities. Most residents travel 50 miles to the north to the Black River each summer for fish. Economy Commercial Fishing Permit Holders 37 Number of Commercial Fishing Permits Issued 43 Gallon of Heating Fuel $7.40 (July 2014) Gallon of Gasoline $7.40 (July 2014) Transportation Transportation Scammon Bay is accessible by air and water. A state-owned gravel airstrip and city- owned seaplane base on the Kun River serve air traffic. Barges bring in bulk supplies each summer. Winter trails exist to Hooper Bay (32 mi) and Chevak (25 mi). Snow machines and skiffs are the primary means of local transportation.

The aquatic investigations were made by ABR and are detailed in their report included in Appendix A. The table below summarizes the fish species identified and approximate locations found. Table 1 – Aquatic Investigation Summary Stream Body Fish Species Observed Approximate Upstream Limit of Presence (river feet) Approximate Elevation (ft) Towak Creek Pink Salmon 640 40 Ekashluak Creek Pink Salmon, Dolly Varden 2400 150 Kawiakpak Creek Slimy Sculpin Hillside Creek Dolly Varden 2670 70 The upstream extent of spawning salmon in Ekashluak is at an elevation of about 150' above sea level. For a project on this stream it is assumed that the powerhouse would be located at this elevation. Additional aquatic investigations would be required to verify whether this location is suitable to prevent impacts to spawning salmon. Dolly Varden in Hillside Creek extend up to an apparent fish barrier located at about an elevation of 70' above sea level. It may be possible to permit a powerhouse at a lower elevation by establishing environmental flows. Additional aquatic investigations would be required. 2.3 Climate The FAA maintains an automated weather/surface observing station (METAR) in Scammon Bay (station ID "PACM"). Raw hourly archive data was obtained (Iowa 2014) and is summarized below for monthly record count, precipitation, temperature, and wind speed. The data was not reviewed and therefore the quality is unknown.

No other resource agencies were consulted in the preparation of this report. Hatch also met with the Scammon Bay Community Council and presented a summary of the feasibility study scope and the results of the preliminary analysis performed to date which indicated that the local creek that runs through the community was the preferred source for hydroelectric development and that it appeared to be economically feasible. The concept of locating the proposed powerhouse to the lowest practical downstream elevation, a site situated on lot 5 of block 12 at an elevation of about 20 feet, was undesirable because of the expected lack flowing water in the creek when it is diverted and bypassed for the purpose of power generation by the hydro project. The lower portion of the creek is utilized for a variety of purposes by the community.

Consequently, the project is within the jurisdictional of the Federal Energy Regulatory Commission (FERC). Refuge permitting requirements consist of a federal right of way application. Transportation and utility systems are allowable within the refuge but final approval may be required from the refuge manager. Authorization from FERC can be obtained by applying for a license or exemption with the latter likely being the preferred means for FERC approval. Additional permits includes the Alaska Department of Natural Resources (ADNR) water rights application requirements for demonstrating rights to access by the development entity and establishing water use quantities. The diversion structure would likely be exempt from ADNR dam safety. The Alaska Department of Fish and Game (ADF&G) provides oversight for protection of aquatic species to ADNR water rights and is also responsible for review of in stream structures and activities. 3. Geology The Askinuk Mountains in the vicinity of Scammon Bay appear to consist of granitic rock. The decomposition at the surface is such that the granitic material can be classified as sand to sandy fine gravel interspersed with cobbles. Occasional larger structures of more competent granite such as the outcropping near the water tank are found in the project area. The sand surface drains well but is also very susceptible to erosion if any surface flow occurs on bare (unvegetated) slopes. The photo below shows the prominent exposed granite feature near the water tank and the active erosion occurring along the access road. Photo 2 -Surface Geology - Road and Prominent Outcropping Near Water Tank Alaska Native Tribal Health Consortium - Hydroelectric Feasibility Study, Scammon Bay, AK Hillside Creek Project Final Report September 19, 2014 Rev. 0 Page 7 © Hatch 2014 All rights reserved, including all rights relating to the use of this document or its contents. Concerns identified in the USACE reports and the Scammon Bay Hazard Mitigation (CSB 2013) report relate to soil erosion caused by melting permafrost. A relatively warm pipeline could increase the depth of the thawed layer in underlying permafrost creating a potential erosion trench/gully. However, no areas of erosion, linked to melting permafrost, were evident in the aerial photo and the vicinity of the water tank. Disturbance of permafrost, if it is present, can be avoided by routing the pipeline in shallow or partially excavated trench in the presumably permafrost free creek valley where snow drifting occurs. Locally obtained bedding can provide for protective cover. More problematic is erosion associated with exposed soils on moderate to steep slopes. Active erosion of exposed decomposed granite caused by rainfall is clearly evident along roads, ditches, and cut and fill slopes. Successful mitigation efforts employed locally include using revegetation, geotextiles, woven fabrics, or surface overlays consisting of coarse gravel, cobbles, or boulders depending on slope being retained and expected runoff. Aside from erosion potential, the soils in the project vicinity are suitable for the development with locally available sand quality bedding, small boulders and cobbles obtainable by screening and suitable for drainage stabilization, and potential for relatively shallow confining and stronger bedrock for the intake and powerhouse although boring or excavation at each site is required to verify. 4. Hydrology The sandy characteristic of the decomposed granite likely allows infiltration most snow melt and rainfall. The result is that local creeks should exhibit stable and relatively high base flows and low runoff peaks. Such characteristics are favourable for the proposed run of river hydro development. Snow drifting, which is evident in winter pictures of Scammon Bay, may be a contributing factor to stream flow as well by providing additional water accumulation and reducing heat loss in the winter. Aerial photos show the creek valley remains snow filled well into the summer season. Search of USGS water resources data website2 for historical stations and individual flow measurements did not produce any results for the creeks of interest in Scammon Bay. Nearby sites that were reviewed include Brown's Creek near Bethel and Takikchak River near Newtok both of which had significantly less discharge per square mile than the values reported by the USACE and Polarconsult for the Scammon Bay area. The hydrology values reported by the USACE in 1985 appear reasonable given the soil and snow conditions. The flow measurement in July, documented in the Hatch Trip Report in Appendix A, were taken after a unusually long dry period followed by a short but wet period3. The flow measurements appear to confirm a respectable base flow and well draining soils 2 http://nwis.waterdata.usgs.gov/ak/nwis/sw 3 Scammon Bay resident recollection Alaska Native Tribal Health Consortium - Hydroelectric Feasibility Study, Scammon Bay, AK Hillside Creek Project Final Report September 19, 2014 Rev. 0 Page 8 © Hatch 2014 All rights reserved, including all rights relating to the use of this document or its contents. with a large storage capacity. This type of condition is well suited to run of river hydro projects which lack storage. The figure below compares the monthly hydrology data from the available data sources above.

Preliminary Analysis Alternatives to diesel generation for Scammon Bay, consistent with findings in past reports, consist of hydroelectric and wind energy generation. This report includes analysis of hydroelectric potential. The Ekashluak project, as originally proposed (AVEC 2003), with a powerhouse located at elevation 20', is not considered feasible because of the salmon habitat. For the preliminary analysis, the powerhouse has been located upstream from the mouth to an elevation of 150' feet. For Hillside Creek, it may be possible to permit a powerhouse at a lower elevation by establishing environmental flows but the resulting benefits are not expected to be worth the costs. When combined with community concerns related to local use of Hillside Creek, the lower powerhouse option on Hillside Creek (Hillside - Alt 1) is not recommended but it is included in the preliminary analysis for reference. The table below shows the results of the preliminary analysis. The results are sufficiently conclusive to establish Hillside Creek as the only viable hydro project at this time. The remainder of this report is entirely concerned with Hillside (Proposed) Project.

Proposed General Arrangement The proposed conceptual design for the Hillside Creek project has been prepared to facilitate the project modeling and analysis and is described below. The concept design is more accurately depicted in the conceptual drawings and detailed cost estimate in the Appendices. The following table summarizes the basic parameters for the proposed project.

As such a geoblock type underlayment is proposed to confine sand like native material and prevent erosion that could compromise the pipeline buried below the surface of the access road. The access road is primarily needed for construction. Once the project is operational access needs are minimal as the intake is designed to be self cleaning. 6.2 Diversion Structure and Intake The primary function of the diversion structure is to impound water for diversion through the intake works. The diversion is a water tight barrier that extends from the flood water elevation down to bedrock across the creek channel. Local materials can be used in the concrete fill that forms the foundation of the structure. The remaining walls would be formed and poured on site except for the spillway which could consist of precast block sections that also incorporate the coanda intake. The intake works consists of a coanda intake, shut off and bypass gates, a domestic water supply priority weir, trash rack, and transition structure. The purpose of the these components is to capture all water available at the intake site, exclude debris from capture and allow debris to be flushed, prioritize captured water into the domestic water conveyance, and finally divert all remaining water into the penstock conveyance without allowing air to enter, ice to buildup, or accidental debris entry into the conveyance. Once or twice a year flushing of sediment, visual inspection, and maintenance of gates may be all that is required for access and maintenance of the diversion structure and intake works. 6.3 Water Conveyance The function of the penstock is to efficiently convey collected water to the powerhouse and turbine for producing electrical energy. The required size of the penstock is based on the economic modeling. If the diameter is too small then there is excessive energy lost in friction which reduces the energy the turbine is able to convert from the flow of pressurized water. Too large of a penstock and the project cost needlessly rises. The analysis performed for this report was limited to looking at single diameter HDPE pipe for the penstock. Analysis shows a 16" diameter penstock is the most economical but a 14" diameter is suitable as well. A combination of sizes along with steel pipe should be considered if the project goes to design. The 16" diameter is chosen for this work. 6.4 Powerhouse and Turbines The turbine and generator package consists of a custom dual nozzle pelton turbine, induction generator, switchgear and controls panels, hydraulic power unit, turbine inlet valve and structural steel equipment mounting frames. The overall turbine and equipment layout is estimated from similar sized projects. Powerhouse construction consists of a concrete foundation and steel building. The location chosen for the powerhouse site is on land owned by the Askinuk Native Corporation. The site Alaska Native Tribal Health Consortium - Hydroelectric Feasibility Study, Scammon Bay, AK Hillside Creek Project Final Report September 19, 2014 Rev. 0 Page 12 © Hatch 2014 All rights reserved, including all rights relating to the use of this document or its contents. is very constrained and access options are limited but it appears that the proposed site plan will be suitable. 6.5 Transmission and Interconnection This project is located within the community with a power pole and distribution line located on the same property as the powerhouse. The cost estimate assumes a transformer is required. 6.6 Controls and Operation The hydro project is expected to operate at maximum output, limited by the water availability at the intake and the maximum capacity, at all times. The hydro operation power would be curtailed when required by the use of an electronic load governor. Standard trips would be incorporated in the switchgear for protection. The concept includes an induction generator because it is assumed that a diesel generator is operating continuously. 6.7 Potable Water Supply Integration The proposed project integrates well with the community's water supply and potable system. Improvements in water system functioning include: Higher water pressure eliminates need for booster pump and improves the filter and backwash systems. An improved diversion structure and the coanda screen intake will reduce maintenance and improve water supply reliability. The risk of water supply contamination is reduced by having the intake located further from the community. The tailrace water could be utilized as a low pressure raw water supply source. 7. Energy Modeling 7.1 Diesel Electric Generation Data on existing diesel electric generation was obtained from the State of Alaska, Alaska Energy Authority Power Cost Equalization Program (AEA PCE) and directly from the electric utility operator AVEC. 7.1.1 Existing Generation Equipment The existing diesel power plant in Scammon Bay consists of 3 engines and is reported to have antiquated controls and switchgear. Planning for a replacement power plant is currently in progress. Because of the limited hydropower potential and lack of stream flow data, this project should not alter the current replacement diesel plant planning and implementation. AVEC is also analyzing the feasibility of wind generation. It is expected that a hydroelectric facility, with a stable and predictable power output, would supersede wind energy in meeting electric demand. This report includes an additional result parameter that shows the amount of Alaska Native Tribal Health Consortium - Hydroelectric Feasibility Study, Scammon Bay, AK Hillside Creek Project Final Report September 19, 2014 Rev. 0 Page 13 © Hatch 2014 All rights reserved, including all rights relating to the use of this document or its contents. demand that could potentially be met by a wind generator when combined with the hydro project. The table below shows the current diesel plant configuration (June 30, 2014 email from AVEC). Table 9 - Existing Diesel Power Plant Configuration Unit # Manufacturer kW Rating Model 1 Detroit 363 S60K4 1800 2 Cummins 350 K19G2 1200 3 Cummins 499 QSX15 G9 7.1.2 Energy Generation AEA PCE data consists of monthly total energy generated.

Heat demand is not considered in this analysis. The performance and economics of the hydroelectric project are analyzed on the basis of the diesel generation costs that can be avoided if the hydro is constructed. Avoided costs include the reduced fuel consumption and, to a certain extent, non fuel costs. Avoided fuel costs are determined using the price of fuel and the potential displaced diesel electric generation in kilowatt hours (kWh). The displaced fuel is determined from the diesel efficiency and fuel use for the base case of diesel only generation less the diesel efficiency and fuel use for the necessary diesel generation with the allowable hydro generation. Allowable hydro generation is constrained by the minimum diesel loading and the amount of excess power available from the hydro. Modeling assumes a minimum diesel loading of 20% of the rated capacity. If the power from the hydro is 10 kW or higher above daily peak demand then it is assumed that a diesel is not needed. Else, if the hydro power exceeds the daily average demand then a diesel is assumed to run at the minimum loading for 12 hours and the energy displaced by the hydro is curtailed as required for the same period. Finally, if the hydro power is less than the average demand then the hydro output is curtailed for 24 hours as required to maintain the minimum diesel loading. Diesel generation efficiency is based on an assumed efficiency profile based on percent load and is scaled to match an expected future average efficiency 14.0 kWh/gal. The efficiency curve, along with the minimum diesel loading, is also based on a typical manufacturer's rating for a single 350 kW engine. Avoided non fuel costs are included in the energy model but are found practically inconsequential because there is essentially no entire day where the demand is low enough for the hydro to carry the entire load. For this reason a diesel generator is required to run nearly all year. Since the maintenance on the diesel power plant is almost exclusively determined by the number of hours the unit runs and is practically independent of load there is very little savings attributable to non fuel costs as a result of hydro operation. The modeling uses $15 per hour for non fuel diesel operation costs. The energy that could be potentially met by a wind generator when combined with the hydro project is calculated using the same assumptions and constraints as above. The displaceable diesel generated electric energy for wind generation, in the chart below, is the modeled electrical demand less the total of the curtailed hydro output plus the minimum diesel generator loading. The following chart shows the daily electrical generation with the proposed project combined with diesel electric generation. The potential wind power is the potential electric demand that could be displaced by wind energy without consideration for storage technologies and Alaska Native Tribal Health Consortium - Hydroelectric Feasibility Study, Scammon Bay, AK Hillside Creek Project Final Report September 19, 2014 Rev. 0 Page 16 © Hatch 2014 All rights reserved, including all rights relating to the use of this document or its contents. resource limitations.

Three of the crew are expected to be local hire which reduces the housing, meals, and travel costs. Additional labor costs include chartered round trip air service from Anchorage occurring every 2 weeks during construction. The costs for construction equipment and material mobilization to and from Scammon Bay is based on a marine shipping quote from Northland for delivery from Seattle to Scammon Bay. Northland operates a landing craft type vessel capable of delivering construction equipment, Alaska Native Tribal Health Consortium - Hydroelectric Feasibility Study, Scammon Bay, AK Hillside Creek Project Final Report September 19, 2014 Rev. 0 Page 18 © Hatch 2014 All rights reserved, including all rights relating to the use of this document or its contents. up to 50k pounds, 20' long stackable shipping containers up to 20k pounds, and 40' long pipe bundles. Pipeline costs are based on weight with the entire penstock constructed from PE4710 pipe with electro-fusion fittings and thicknesses ranging from SDR 26 to SDR 9. The cost of delivered pipe is based on the total weight and the number of shipping bundles required. Turbine costs were quoted by Canyon Industries, an American manufacturer. The quote included a complete package consisting of the turbine, generator, controls, and switchgear. Contractor installation is assumed along with additional costs for control integration. 8.2 Schedule The schedule is based on an assumption that development begins following successful funding through the State of Alaska Renewable Energy Fund (REF) grant program starting with an application for design and permitting in 2014 followed by 3 years of permitting then construction funding being awarded through the REF program in 2018. Table 14 - Proposed Development Schedule Description Start Finish Permitting and Design Jul-2015 June-2018 Construction Jul-2018 Oct-2018 9. Economics Evaluation of the proposed project is made by comparing the net present cost and benefits with the base case of diesel electric generation. A planning horizon of 50 years and a discount rate of 3% is used for the analysis. Uniform inflation is assumed for all costs except for diesel fuel costs which are expected to escalate at a rate of 1.5% greater than inflation. All results are reported in 2014 dollars (inflation excluded). Electric demand is expected to grow at a rate of 2% annually. 9.1 Diesel Fuel Cost The price of diesel fuel for electric generation averaged $3.59 per gallon for FY 2013 (7/1/2012 through 6/30/2013). Inquires with AVEC and a review of filings with the RCA did not result in any updated fuel pricing information. It is estimated that the most current price for delivered fuel in Scammon Bay is about $4 per gallon. The economic modeling for this study uses the current fuel price estimate of $4.00 per gallon escalated by a rate of 1.5% per year (above inflation). 9.2 Economic Evaluation Method The parameters reported in the results table are generation related components of the total annual costs calculated over the planning horizon and adjusted for year of occurrence using Alaska Native Tribal Health Consortium - Hydroelectric Feasibility Study, Scammon Bay, AK Hillside Creek Project Final Report September 19, 2014 Rev. 0 Page 19 © Hatch 2014 All rights reserved, including all rights relating to the use of this document or its contents. the discount rate. Conclusions are shown in two ways: the net present cost of generation and the benefit/cost ratio. The two methods present two different viewpoints on project benefits. 1. The Net Present Cost of Generation (NPC) presents the results from the viewpoint of a consumer to illustrate which of the projects, including the no hydro alternative of diesel only, provides the lowest cost of power. 2. The Benefit/Cost Ratio (B/C) presents the results from the viewpoint of an investor and illustrates whether the benefits of the proposed development are greater than the cost (i.e., B/C >1). The following describes additional detail on the economic parameters. Net Present Cost of Generation - Diesel Electric. The net present cost of electric generation using diesel is the sum of the diesel fuel costs, inflated as indicated, and the generation related O&M costs over the planning horizon. Costs are discounted based on the year of occurrence. This is the base case from which the benefits of the hydro option are determined. Costs not associated with generation, such as distribution system maintenance and administrative services, are not included. Net Present Cost of Generation - Hydroelectric. The net present cost of electric generation with the addition of the hydro. Where the hydro is unable to meet demand the necessary diesel generation expense and associated diesel O&M expense is included in the annual cost. This includes the cost of generating power from the present year on which is entirely diesel only generation until the hydro is commissioned. The cost to construct the hydro and the O&M cost of the hydro are also included. When the NPC of hydro generation is less than diesel electric generation the proposed project is superior. Net Present Value of Hydro Development Cost. Used for B/C calculation, the present value of the of the hydro development cost is the cost component in the B/C Ratio. This is the sum of the costs, over the planning horizon, to develop the hydro discounted by the year the costs occur. Only costs to develop and construct the project are included. Net Present Value of Hydro Benefits. Used for B/C calculation, the present value of the annual cost savings from the hydro is the benefits component in the B/C Ratio. This is the sum of the benefits, over the planning horizon, to develop the hydro discounted by the year the benefits occur. The benefits of the project are defined as the cost of generation using diesel only minus the cost of hydro generation for each year. The cost of hydro generation includes the fixed O&M cost of the hydro, the cost of diesel fuel from required diesel generation needed to meet demand, and the associated diesel O&M cost. Costs to generate power from present day through hydro development are included (benefits are zero until project is commissioned). B/C Ratio. This is the present value of the hydro benefits divided by the present value of the hydro development cost. When greater than 1.0 the proposed project is superior.

Conclusion and Recommendations Conclusions The Hillside Creek hydroelectric project is a viable addition to electric generation in Scammon Bay that should be investigated further through design and permitting efforts. Future work should include a focus on stream flow data collection, conceptual design improvement, community and other stakeholder consultation, initial permitting actions, land acquisition, potable water system integration, and compatibility and economics with wind generation and diesel heat recovery projects. Project design would follow if it is decided to construct the project. Recommendations The hydrology data is not adequate to recommend a project size for final design and permitting. Collection of stream flow data on Hillside Creek will be required if the project proceeds to design and permitting. It is recommended to install a stream gauge and collect 2 to 3 years of flow data for project design and permitting.

Introduction The purpose of the site to Scammon Bay was to investigate local conditions and evaluate the presence, or lack of, of fish in the streams near Scammon Bay to better understand the potential for hydroelectric development. Daniel and John traveled to Scammon Bay on 21 July 2014 via Alaska Airlines out of Anchorage and Grant Aviation out of Bethel (twin engine Navajo). Weather nearly prohibited successful arrival in Scammon Bay due to very strong cross winds. Daniel and John were housed at the new water treatment plant for their stay. On the following day, 22 July 2014, weather was decent and the boat rental was arranged to perform the aquatic investigations at Ekashluak Creek. After returning to Scammon Bay minnow fish traps with bait were set in Hillside Creek. Flow measurements were also taken. The following day, 23 July 2014, traps were pulled from Hillside Creek followed by electro fishing in the vicinity of the proposed powerhouse site. A community council meeting was also being held that day where Daniel was able to present the current understanding of development options and obtain comments and feedback from the council members. Daniel and John departed Scammon Bay that afternoon, 23 July 2014, on a Cessna Caravan and returned to Anchorage that evening.

Weather Local residents indicated that the creeks were very low as of a month ago until a significant amount of rain fell over the past two weeks. For the period of July 1 through July 24 the average temperature was 53 deg F and 7.41 inches of rain fell according the FAA ASOS station PACM1. The chart below shows the temperature, wind speed, and precipitation from July 1 through 24. 3. Aquatic Investigations John performed the aquatic investigations and will file a trip report with the Alaska Department of Fish and Game and make anadromous nominations as required by regulation. The following is a summary aquatic investigation results. Investigations for fish species presence was made on Towak Creek, Ekashluak Creek, Kuwiakpuk (unsure of spelling) Creek, and the unnamed (Hillside) creek that runs through the community of Scammon Bay.

Flow Measurements The flow in the unnamed (Hillside) Creek was measured three times during the site visit and was determined to be approximately 3.7 cfs on July 22 and 3.8 cfs on July 23. Measurement reports are attached. The following table summarizes the measurements. Date and Time Location Discharge (cfs) 21:40-22-Jul-2014 Hillside Creek fish barrier 3.8 21:54-22-Jul-2014 Hillside Creek fish barrier 3.7 14:32-23-Jul-2014 Hillside Creek fish barrier 3.8 5. Community Council Meeting Daniel provided the council with a summary of the feasibility study scope and the results of the preliminary analysis performed to date which indicated that the local creek that runs through the community was the preferred source for hydroelectric development and that is appeared to be economically feasible. Mr Hertrich also suggested using Hillside Creek and Hillside Hydroelectric Project as names in the study for the unnamed creek that runs through Scammon Bay and the proposed hydroelectric scheme. The concept of locating the proposed powerhouse to the lowest practical downstream elevation, a site situated on lot 5 of block 12 at an elevation of about 20 feet was undesirable because of the expected lack of flow when the creek is bypassed by the hydro project. The lower portion of the creek is utilized a variety of purposes by the community. 6. Recommendations Establish the proposed powerhouse site at an elevation of approximately 70' so that it is located above the fish barrier. This will eliminate complications with bypass flow requirements for aquatic species and alleviate concerns bypassing the portion of the creek that runs through the community.

Box 240268 Fairbanks, AK 99524 August 2014 ________________________________________________________________________ INTRODUCTION In the spring of 2014 the Alaska Native Tribal Health Consortium (ANTHC) requested a feasibility study to determine the potential for hydroelectric projects near Scammon Bay, Alaska. Hatch prepared an analysis of the potential for hydroelectric projects on several small, high gradient streams in the Askinuk Mountains that flow north into the Kun River and Kongishluk Bay. Hatch requested that ABR, Inc—Environmental Research and Services (ABR) provide assistance in determining whether resident and anadromous fish populations exist in these streams. The objectives of this survey were to 1) assess the likelihood of resident or anadromous fish presence in the streams to be surveyed and 2) perform basic assessments of stream habitat conditions (e.g., gradient, flow). METHODS ABR biologist John Seigle travelled to Scammon Bay during 21–23 July 2014. On 22 July, John Seigle and Dan Hertrich (Hatch) travelled by boat with local hires to 3 streams, each with a general south to north flow regime emanating from the Askinuk Mountains and draining into ABR, Inc. 2 Scammon Bay Hydroelectric Feasibility Survey Scammon Bay. A fourth stream, located in the village of Scammon Bay was also surveyed during 22–23 July. From east to west, starting in Scammon Bay, these streams were Hillside Creek, Towak Creek, Ekashluak Creek, and Kawiakpak Creek (Figure 1). Visual observations of stream conditions and fish presence were made at Towak Creek, Ekashluak Creek, and Kawiakpak Creek. Fish surveys in Hillside Creek included visual observations and the use of minnow traps and a backpack electrofisher. During visual observations of fish presence, the stream corridor was surveyed downstream to upstream to the point at which the last spawning Pink Salmon (Oncorhynchus gorbuscha) was observed. GPS locations were marked for large spawning aggregations and to identify the upstream extent of observed spawning Pink Salmon. A photo log, including photos of spawning Pink salmon, was kept for each surveyed stream. Minnow traps were deployed in Hillside Creek during the evening of 22 July. A total of 9 traps were deployed in the lower creek starting near the creek’s confluence with the Kun River and extending upstream to what community members described as a barrier to upstream fish movement. An additional 2 minnow traps were deployed upstream of this apparent barrier. Minnow traps were baited with salmon roe which had previously been disinfected with a betadine solution. Traps were allowed to fish overnight and were retrieved on 23 July. All captured fish were identified to species, enumerated, and measured for fork length (mm). Fish were then returned live to the stream. Limited electrofishing was conducted upstream of the presumed barrier to upstream fish movement on Hillside Creek. Prior to fishing above the barrier, the electrofisher was tested in a small pool just below the barrier to ensure that the electrofisher settings were sufficient to stun juvenile fish without causing mortality. Once it was determined that the settings were correct, the stream was electrofished above the barrier. As Hillside Creek is primarily a high gradient plunge pool stream, electrofishing took place in a pool by pool basis for a total distance of ~500 feet upstream of the presumed barrier to fish migration. ABR, Inc. 3 Scammon Bay Hydroelectric Feasibility Survey INITIAL FINDINGS TOWAK CREEK The survey team observed Pink Salmon spawning at the mouth of Towak Creek (Table 1, Figure 1). While most spawning was limited to a series of pools near the mouth, several other spawning salmon were observed up to ~640 river feet upstream. There were no obvious barriers to salmon movement upstream from this location. However, the survey team walked an additional ~1,000 feet upstream without observing fish (Plates 1–5). EKASHLUAK CREEK Pink Salmon were observed at numerous locations from the stream mouth to ~2,400 river feet upstream (Figure 1). Though there were no barriers to immediate upstream movement of salmon, the substrate in this area of the stream began to transition from mixed gravel, cobble, and sand to larger boulders and cobble that are less suitable spawning habitats for Pink Salmon. The survey team hiked several hundred feet upstream of the upper-most observed salmon before returning to the boat. Several smaller fish were observed swimming throughout the stream over the observed area. A number of high gradient plunge pools were observed at the upper extent of the surveyed stream. It was thought that fish observed in or near these pools were likely Dolly Varden (Salvelinus malma). The stream itself is well oxygenated, with low conductivity and slightly acidic water (Table 1) (Plates 6–10). KAWIAKPAK CREEK The lower portion of Kawiakpak Creek near the mouth of the stream was high gradient (>5%) and unsuitable for migrating salmon. However, slimy sculpin (Cottus cognatus) were observed. The survey team walked upstream to several pools in search of additional fish species but none were observed (Plates 11–13). HILLSIDE CREEK Hatch had previously determined that the likely most economical project stream was Hillside Creek located in the community of Scammon Bay. Prior to fish sampling, we talked with community members to determine what fish might be present in this high gradient stream and to locate the likely upstream extent of fish migration. The children of the community often ABR, Inc. 4 Scammon Bay Hydroelectric Feasibility Survey fish for Dolly Varden (which they refer to simply as trout) in various plunge pools from the mouth upstream to a series of cascades that presumably act as a barrier to upstream migration for fish. A total of 31 Dolly Varden were captured in the minnow traps downstream of the presumed barrier to fish passage (Table 2). No fish were captured in minnow traps deployed upstream of the barrier. Electrofishing above the presumed barrier similarly captured no fish. Test electrofishing below the barrier was effective (~4 juvenile Dolly Varden surfaced), indicating that voltage settings were adequate to capture fish, had they been present above the barrier (Plates 14–20). SUMMARY The 3 streams surveyed to the west of Scammon Bay are not economically feasible hydroelectric project streams. Still, the results of visual observations in these streams will assist fisheries managers attempting to understand salmonid distribution in the region. ABR will nominate Towak Creek and Ekashluak Creek to the ADFG Anadromous Waters Catalog (AWC). Although survey efforts were minimal in these smaller streams, information gathered here will provide some of the first observations of salmonids in tributaries to the Kun River emanating from the Askinuk Mountains. No Pink Salmon were observed in the lower reaches of Hillside Creek during late July surveys in Scammon Bay. However, Dolly Varden are present throughout the lower reaches of the stream up to a set of barrier falls located at the south end of the village at ~70 feet elevation. Future discussions on hydroelectric facilities on Hillside Creek must consider fish passage and fish habitat issues related to Dolly Varden as required by the State of Alaska under the Anadromous Fish Act (AS 16.05.871) and the Fish Passage Act (AS 16.05.841).
