The main purpose of the reconnaissance study was to evaluate the nature of the resource and determine if there is potential for electrical generation to serve Hoonah and possibly Pelican. The resource is located near the head of Tenakee Inlet on northern Chichagof Island, in southeast Alaska. The resource is characterized at the surface by at least four small hot springs that occur together on the southeast side of Tenakee Creek located at approximately 57°59’24” N and 135°56’20” W. These hot springs have been scientifically documented in several geologic publications since at least 1980, and tested for composition and temperature. The reported surface temperature of the hot springs is 176°F. The Tenakee Inlet Geothermal Resource Project started in August 2011 after notice of award. The project was funded through a renewable energy grant administered by the Alaska Energy Authority (AEA). Hattenburg Dilley & Linnell (HDL) was contracted by Inside Passage Electric Cooperative (IPEC) to manage the project, conduct field studies, and evaluate the geothermal resource. Table 1 presents the geological and other reports that have been submitted on this project to AEA. The interim report was a description of the fieldwork and data collected up to December 2011. The Geothermal Resource Council paper was presented at the national conference and is in the proceedings of the conference. The preliminary environmental report presented the different permits needed for the project and agencies that would be involved if the project moved to construction. The preliminary conceptual report presented the geological model for the geothermal resource. The economic analysis evaluated five alternative sites and two alternative power transmission options.

The individual documents listed in Table 1 present more detail on each aspect of the project. 2.0 PROJECT DESCRIPTION The Tenakee Inlet geothermal resource is located approximately 19 air miles southwest of Hoonah Alaska along an un-named river we have called Tenakee Creek. Figure 1 presents a vicinity map. There is a number of hot springs on Chichagof Island as shown by black circles on the vicinity map, however, Tenakee Inlet hot springs have the hottest surface temperature of any of the springs on Chichagof Island. The area is characterized by rugged, steep terrain covered with thick vegetation typical of southeast Alaska rainforest. The topographic highs limited the exploration area to the valley floors and to the first bench above the river valley. The resource surface expression consists of four small hot springs that occur at the base of a slope on the southeast side of Tenakee Creek located at approximately 57°59’24” N and 135°56’20” W. The focus of the study area was the immediate hot springs area and approximately % to % square mile surrounding the hot springs. As the data gathered from the different field studies were interpreted, additional field areas were studied in order to provide a boundary on the resource. Figure 2 presents the study area. There are two boundary streams that bounded the original study area on the southwestern side and northeastern side. The hot springs area is small about 50 feet long by 20 feet wide occurring on a gravel bar that is heavily vegetated with alders, willows, and spruce trees. The gravel bar is approximately 800 feet long and 200 feet wide. The terrain rises steeply on both sides of the stream channel. The hot spring site and the location of the four hot springs are shown in Figure 3. There is an outflow creek from the spring site that leads to Tenakee Creek. A stream named the Stairway to Heaven Creek cascades down the slope and mixes with the outflow near the spring site. Seeps occur along the shore of the gravel bar and are periodically inundated by Tenakee Creek. In order for the resource to be developed a well field, power plant site, access road, and transmission line to connect a power plant to Hoonah will be required. Prior to actual construction of the facilities mentioned, a more comprehensive exploratory phase that will have to include advancing one or several deep drill holes and testing of the exploratory wells will be needed. The number of exploratory and final production wells will depend upon the flow rate and temperature of the fluids encountered. The flow rate will only be determined after an exploratory well is installed and well tests are conducted. Additional exploratory wells may be needed or depending upon the results of the well testing, a production well(s) will be designed. A production well field will be developed near the resource depending upon the findings presented in this report as well as future exploratory drilling. The production wells will feed fluids to the power plant. The power plant site is anticipated to be about 5 to 7 acres in size. Due to the Tenakee Inlet Reconnaissance 2 ADI Arnau unnen, Engineering Consultants nature of the resource, a binary power plant is anticipated. As an alternative to the transmission line and the power plant in the stream valley near the well field, we also considered a pipeline from the well field to a power plant located outside of the Tenakee Creek valley. The January 2008 Tongass National Forest Management Plan Land Use Designations Map (USFS 2008) outlines a potential power transmission line route that links the communities of Hoonah and Pelican. In the 2004 ADOT&PF Southeast Alaska Transportation Plan, a similar route is also identified as a future road corridor. In 2006, the USFS signed a Memorandum of Understanding with the State of Alaska to provide rights-of-way for this and other road corridors. The actual design of the road has not been prepared and the existing conditions along the corridor were not considered part of this reconnaissance effort beyond aerial observations of the corridor. The HIA has been making an effort to extend the existing road system out from Hoonah towards the resource along this corridor and using existing forest service roads. 3.0 REGIONAL CHARACTERISTICS Chichagof Island is dissected by numerous bays, inlets, and fjords with an irregular shoreline. Numerous short streams with steep gradients occur on the island. Flow is highly variable throughout the year and the streams respond rapidly to precipitation. Glaciation has significantly altered the landscape. Vegetation is heavy timber typical of temperate rain-forest. 3.1 Climate Climate in the region is a maritime climate characterized by cool summers and mild winters. Foggy periods typically occur in the spring and fall. Summer temperatures in Hoonah average 52°F to 63°F; winter temperatures average 26°F to 39°F. Temperature extremes have ranged from -25°F to 87°F. Precipitation in Hoonah averages 100 inches annually with 71 inches of snowfall. Tenakee Springs located to the south of the project area has slightly cooler summer temperatures and less precipitation. Total precipitation in Tenakee Springs averages 69 inches a year with 62 inches of snowfall. During our fieldwork in September and October 2011, we established a small weather station at the base camp near the hot springs location. The temperatures ranged from 36°F to 48°F. Precipitation occurred on six of the 15 field days and ranged from 0.04 inches to 1.02 inches. The 1.02 inches occurred on September 28, 2011 the day after the 0.04 inches. The rainfall was recorded at 10:30 am. During additional field visits in March and April 2012, the hot springs and the outflow were snow-free with approximately seven to eight feet of snow cliffs bounding the outflow area. An additional visit on February 19, 2013 indicated several small avalanches in the area and thick snow piles. The helicopter on this trip was unable to land at the designated Tenakee Inlet Reconnaissance 3 HOD Yee’ DILLEY & LINNELL Engineering Consultants landing spot near the hot springs due to the instability of the snow pack. There had been several small earthquakes prior to that visit most likely causing the avalanches. 3.2 Topography Chichagof Island is fairly mountainous and of moderate relief. Major peaks reach a height less than 4,000 feet. Although glaciation has modified the landscape there is only one present-day glacier on Chichagof Island. The ice sheet during the Pleistocene covered all but the highest elevations on the island and minimum elevation was between 2,400 to 2,700 feet. In the mountainous terrain glacial erosion features such as cirques, horns, arétes, and U-shaped valleys occur. These glacial features have been further modified by steep gradient streams creating V-shaped river valleys such as Tenakee Creek. Dense forests occur throughout the island. Hemlock and spruce are the dominant forest trees. The dominant undergrowth of alder, devils club, and berry bushes is nearly impenetrable in places. Timberline varies but generally ranges from 2,000 to 2,600 feet on Chichagof Island. The hot springs occur at the base of a vegetated slope on a gravel bar. The gravel bar has approximately 10 feet of elevation change across the 200 foot width. Spruce, hemlock and alder occur on the gravel bar which is approximately 800 feet long. The slope rising from the hot springs to the southeast has a gain of approximately 200 feet in about 300 feet horizontal distance. There is a steeply incised creek canyon named Stairway to Heaven (by the field team) located approximately 50 feet east of the hot springs. Freshwater from the slope flows from this creek and mixes with the hot spring outflow which meanders to the east along the base of the slope towards Tenakee Creek (Figure 3). Across Tenakee Creek to the northwest from the hot springs, the river canyon slope rises approximately 100 feet over 160 feet. At the top of these slopes is a gentler slope composed of wetland vegetation with trees (Figure 4). The wetlands are composed of thick, wet, organic soils and bogs. 3.3. General Geology The Tenakee Inlet area is composed of Devonian age argillite, graywacke and limestone that were subsequently intruded by wide variety of igneous rocks. These rocks outcrop near the study area and to the north of the study area. Figure 5 presents a geologic map of the area. The intrusives vary in age but are primarily Cretaceous in age and in the study area is mainly diorite to granodiorite in nature. These rocks are widely distributed on Chichagof Island. On Figure 5 these rocks are represented in yellow with a Kd symbol. To the south of the study area is a large body of Tertiary intrusives consisting of hornblende leuoconorite and troctolite. The Devonian age sedimentary rocks have undergone extensive regional and contact metamorphism. The intrusives have metamorphosed the sedimentary rocks into Tenakee Inlet Reconnaissance 4 PADI arn ey a unne Engineering Consultants hornfels, and marbles. On Figure 5 these rocks are represented by Pzh/Pzm symbol and occur to the northwest of the study area. The rocks are intensely folded and faulted. The fold axes trend northwest. 3.4 Structural Geology The structural geology of the area is dominated by the Queen Charlotte-Fairweather fault system and the Chatham Strait Fault. The Queen Charlotte-Fairweather fault system lies to the immediate west of Chichagof Island and the Chatham Strait Fault defines the Chatham strait between Chichagof Island and Admiralty Island to the east. The faults of the Queen Charlotte-Fairweather system are active right-lateral structures with large displacements. The Chatham Strait Fault offsets rocks as young as middle Tertiary and by as much as 90 miles. (Gehrels & Berg 1994). The Queen Charlotte-Fairweather fault system defines the plate boundary of the Pacific plate and North America. In the middle Mesozoic prior and/or concurrent with the intrusion of the igneous rocks in the study area, southeast Alaska was involved in subduction of the Pacific plate beneath North America (much like the present day Aleutian Trench), which over time evolved into the dominant transform plate boundary seen today (similar to the California San Andreas Fault system). This tectonic activity has resulted in a complicated patter of thrust faults, oblique slip faults, and strike-slip faults on Chichagof Island. The major faults define micro-plates termed tectonostratigraphic terranes. The rocks in the study area are part of the Alexander Terrane. Based on paleomagnetic, structural, and stratigraphic data, the Alexander Terrane has moved northward relative to its original sites of deposition and to North America. The rocks of the Alexander Terrane are interpreted to represent intermittent volcanic arc activity and the terrane is inferred to have continental origins (Karl 1999). Modern earthquake activity occurs along the Queen Charlotte-Fairweather fault system (Figure 6). The most recent large magnitude earthquakes in the area of the hot springs occurred in 1939 and 1927 (Alaska Earthquake Information Center). A magnitude 6 occurred in 1939 at latitude 58.00 and longitude -136.0. A magnitude 7.1 occurred in 1927 at latitude 57.69 and longitude -136.07. The hot springs are located at latitude 57.99 and longitude -135.93. 3.5 Hydrology Tenakee Creek has a watershed of approximately 27 square miles, ranging in elevation from Pegmatite Mountain at 3,500 feet to sea level at the mouth. The watershed includes glaciers, tarn lakes, steep mountain slopes, U-shaped glacier-carved valley walls, steeply incised narrow canyons, waterfalls and broad sloping muskeg terrain. In the vicinity of the hot springs the creek flows in a channel ranging from 30 to 80 feet wide, depending on flow. Depths ranged from one to four feet, with some pools deeper than five feet at scattered intervals along the creek. From a mile upstream to just below Tenakee Inlet Reconnaissance 5 ADIL reese user une. Engineering Consultants the hot springs area, Tenakee Creek is incised in a steep-walled canyon ranging from 100 to 250 feet deep and about a quarter mile wide. Flow rates and volumes are not available for Tenakee Creek, but one observed fact is that the drainage is extremely and rapidly responsive to local rainfall. During the course of the investigation, the creek was observed to rise rapidly and fall rapidly, apparently in direct response to rainfall events. In a 24 hour event (Wednesday- 9/28/11) with 1.02 inches of recorded rainfall, the river rose at least 2.5 feet in the vicinity of the hot springs, then subsequently receded one-foot the day after, another half-foot the second day after. The rise in river level was so rapid on that occasion the landing zone flooded and crew had to be evacuated on short notice. Subsequent field efforts included collecting flow data on Tenakee Creek. The hot springs bubble up into a small pool which drains out through a 400 foot-long channel along the base of the steep valley wall, parallel to and then merging with Tenakee Creek (Figure 3 and 4). When creek flow was high (near the vegetation line on the river bank), the hot spring outflow was discharging directly into the creek. However when the Tenakee Creek level dropped to two to three feet below the vegetated riverbank, outflow in the spring channel ceased. At the same time, vapors were observed welling up from the exposed creek bed, particularly in the area slightly downstream of the hot springs. Numerous small outflows were observed within the creek sediments, and the rocks and sand deposits were warm to the touch. It is likely that the coarse floodplain sediments are quickly flooded then drained in concert with the creek level. This rapid response alternately constrains the outflow to its channel when the creek is high, then facilitates a lateral flow of hot spring water toward the creek bank when low. These small outflows were termed seeps and alternately may represent springs not directly connected to the outflow. 4.0 LOCAL AND REGIONAL ECONOMY Hoonah is the only first-class city on Chichagof Island, the 109th largest island in the world and the 4th largest island in the United States. Hoonah provides all municipal services including police, utilities and road maintenance. At the 2000 census the population was 860, though summer population can swell to over 1300 depending on fishing, boating, hiking and hunting conditions. There has been a decline in the population since the 2000 census to a population of 753 in 2011. There are 399 housing units in the community. Fishing and local government are mainstays of the economy. The existing cold storage plant was closed this year due to the high energy costs. The school uses waste heat from the diesel generators to heat the facility and the community pool. Tourism, as a private sector economic stimulant, has developed into a major industry. Subsistence activities remain important components of the lifestyle. Salmon, halibut, shellfish, deer, waterfowl, and berries are harvested. Tenakee Inlet Reconnaissance 6 POD ees DILLEY & LINNELL Engineering Consul tants The 2006 through 2010 American Community Survey (ACS) estimated 330 residents as employed. The public sector employed 32.1 percent of all workers. The local unemployment rate was 8.1 percent. The percentage of workers not in labor force was 37.7 percent. The ACS surveys established that average median household income (in 2010 inflation-adjusted dollars) was $50,511 (+/-$14,015). The per capita income (in 2010 inflation-adjusted dollars) was $24,426 (+/-$4,057). About 12.2 percent of all residents had incomes below the poverty level. The old fish cannery, which ceased operations in the 1950’s, located near Icy Strait was obtained by the Hoonah Indian Association (HIA). The road to the site, Cannery Road was paved in 2000 and the site was converted into a visitor center and tourism destination for cruise ship passengers. From May through September, three to four cruise ships anchor off Icy Strait Point and visits from ship passengers enhance Hoonah's warm weather economy. Hoonah, being an island community, is only accessible by boat or plane. The Alaska Marine Highway serves Hoonah with day boats. The airport is service by bush carriers Wings of Alaska and Alaska Seaplanes with up to five flights a day between Hoonah, Juneau and local communities. Tongass National Forest borders the area and has an unpaved road system of over 300 miles. Many of the recreation areas including Game Creek, Kennel Creek, Freshwater Bay which has a small boat harbor and Whitestone boat landing and False Bay recreation area are accessible during the summer months via these roads. 5.0 CURRENT ENERGY DEMAND The current energy demand is from the businesses and residents of Hoonah. There are no major industries such as a fish processing plant at this time that would increase demand during a specific part of the year. IPEC operates four diesel-powered generators in Hoonah with combined capacity of 3,060 kW. Overall efficiency is 14.25 kWhr/gallon of fuel. Annual electricity usage in Hoonah is 4,860,308 kWhr. IPEC used 331,184 gallons of diesel per year generating electricity at Hoonah. At a cost of $4.12 (IPEC’s price in 2012) per gallon, diesel costs for power generation totaled $1,364,000 per year. In the past IPEC has experienced anywhere from 5 percent to 50 percent increase in fuel prices. The last few years have seen extreme variations in the fuel prices in relatively short periods of time. The cost paid by residential users is offset by Power Cost Equalization (PCE) funds. According to the State’s FY 2011 PCE Statistical Report residential rates in Hoonah averaged $0.60/kWhr. Approximately 30 percent of the cost is credited back to a residential user. Space heating is the other component of energy consumption in Hoonah. Space heating costs represent a major portion of residential, commercial, and industrial energy expenditures in Southeast Alaska. Historically most of the space heating has used diesel. Tenakee Inlet Reconnaissance 7 PADI ree muerte, Engineerin| 9 Consultants According to the Southeast Alaska Integrated Resource Plan, Hoonah uses 238,235 gallons of heating oil per year (2012) at a cost of $1,093,805. Electric heating systems are generally less efficient than other heat energy sources in Alaska. However, with cheaper energy these electrical heating systems can provide an attractive alternative. There has already been a switch as hydroelectric facilities come online and reduce the cost of electricity. When oil prices increased significantly in 2008 and again in 2010 and 2011, many customers in areas with low-cost hydroelectric generation converted to electric heat. This conversion significantly increased electric loads consuming excess hydroelectric generation resources and, in some cases, resulted in the operation of diesel generation when water levels of the hydroelectric projects dropped to unacceptable levels. We have conservatively estimated that geothermal produced electric energy could replace 25 percent of the space heating needs for Hoonah. A new hydroelectric facility is being developed at Gartina Falls near Hoonah. It is anticipated that construction will be completed between 2015 and 2018 and supply approximately 30 percent of the current energy demands for Hoonah. As energy demand increases, this facility will still only supply a certain amount and does not provide for increases in energy demand. We have adjusted the diesel costs for power generation by using a reduction of 30 percent this year but maintaining that number constant over time. Table 2 presents the diesel costs for Hoonah. Table 2: Diesel Costs for Hoonah City Diesel Costs | TotalSpace | 25% ofSpace | Total Diesel Displace for Power Heating Fuel | Heating Fuel Costs Generation Costs Costs Hoonah $1,364,000 $1,093,800 $273,450 $1,638,000 (2012) Hoonah w/ $954,800 $1,093,800 $273,450 $1,228,250 (2015- Gartina 2018) 5.1 Operating & Maintenance Costs IPEC is a non-profit, consumer-owned and governed electric utility which services 1,300 members in Southeast Alaska. For 2012 the average cost per kWhr sold was $0.5983. This price included operation and maintenance (O&M) costs, fuel costs, direct administration costs, and other indirect costs. O&M costs for a geothermal power plant include routine oversight of plant operation and visual inspections by plant operators and maintenance to repair and replace parts as needed. Routine resupply of consumables is also needed. Ormat estimates the O&M costs for a Mt. Spurr geothermal project to lie in the range of $0.03 to $0.06 / kWhr, which is in the expected range for geothermal power plants. Akutan geothermal project estimates O&M costs at about $0.08 / kWhr. A plant at Tenakee would likely have O&M costs at the high end of this range much like Akutan, due to the small scale and remote location. The O&M Tenakee Inlet Reconnaissance 8 HOLY Ss DILLEY & LINNELL Engineering Consultants costs for the geothermal plant will be incorporated into the administrative costs for IPEC. Of the $0.5983 average cost per kWhr sold, approximately 49 percent is for fuel costs. The $0.08/kWhr will replace some of the fuel costs and O&M costs. 6.0 METHODS The various field efforts are detailed in Table 3 as well as the goal of each field effort. For the majority of the project, the same HDL personnel were involved in the various field efforts. Each field effort longer than one day was based out of Hoonah and supported with full-time helicopter transport provided by Coastal Helicopters. Daily trips were based in Juneau. The field team consisted of surveyors, professional engineers, and geologists. Several landing zones were established and used for the majority of the field efforts; additional one-time landing spots were determined by the helicopter pilots as needed. A grid was developed based on 300 feet by 300 feet squares prior to the fieldwork. This grid and study area proposed was originally condensed due to topography, vegetation, and subsurface temperature information obtained. However as the field data was interpreted additional areas were studied. Table 3: Various field efforts conducted for the study Field Trip Dates Purpose Original 9/22/11 - 10/8/11 Collect water, soil, temperature Reconnaissance samples, general observations Winter 3/7/12 Snow pack thickness, install stream Reconnaissance gages, flow rate of stream and outflow Download Trip/ 5/21/12 Download data loggers FLIR Reconnaissance FLIR camera collection, download dataloggers Second Summer 8/20/12-8/26/12 Additional temperature collection, Reconnaissance stream cross section survey, flow rate (Trip 1) of stream, test pits to determine groundwater flow on “hot-spring’ island, download dataloggers Second Summer 9/20/12-9/23/12 CO2 survey, additional temperature Reconnaissance collection, decommission dataloggers (Trip 2) Engineering 2/19/13-2/20/13 Observe power plant sites and Overview corridors for road and transmission lines Tenakee Inlet Reconnaissance 9 IDE See erste Engineering Consultants A Special Use Permit from the US Department of Agriculture, Forest Service was obtained. The permit allowed HDL to conduct the fieldwork at the hot springs location and the surrounding areas. Coordination with the Forest Service personal was conducted due to bear hunting season and potential conflicts with bear guides. An operations plan was established for the orderly acquisition of field data, with provisions to flex the plan as conditions dictated. Fieldwork consisted of collecting shallow temperature data, and soil, water and rock samples from various locations surrounding the hot springs and the immediate vicinity. The established grid was used to systematically collect temperature data and soil samples. Water and rock samples were more varied and were dependent upon the location of the samples to the hot springs. 6.1 Survey Control Three survey control points were established and two-inch aluminum caps were set (two near the hot springs and one on the east side hill) in order to maintain accurate survey control for future fieldwork and development. The three control point coordinates are provided in Table 4. A rectangular grid was then established from the base line onto the surrounding hot springs area. GPS coordinates were collected at grid points. The grid points were used as the locations to collect the soil samples and install the shallow temperature probes. The field crew started from the hot spring location and work outward in a spiraling pattern to gather the field data, with tightly-defined 100-foot spacing nearest the hot spring, then expanding to 300-feet spacing. The grid baseline was define as “A” and was aligned through the hot springs. The hot springs occurred at grid point “A4”.

Table 5 presents the samples obtained, the laboratory used for analysis and the parameters analyzed. Samples were submitted to respective laboratories for analysis. From September 27 through September 30, Lorie Dilley of HDL and Joe Moore, a geothermal researcher with Energy & Geoscience Institute (EGI) visited the site and made some revision in the collection points and sampling intervals in accordance with the temperature findings and the discovery of hot seeps into the main river.

The equipment included 5-1/2 foot long sections of 3/4” steel pipe for probes, TAC (temperature acquisition cables), and dataloggers to record the temperature measured by the TAC. The steel pipe was fabricated into a probe to insert in the ground by welding one end closed and hard facing it to allow it to penetrate hard ground. Forty probes were fabricated and reused during the field work. Two areas (Figure 7), designated as Area 1 and Area 2, were investigated using shallow temperature probes and single-point temperature acquisition cables (TACs). The shallow temperature probes in Area 1 were conducted to establish a tighter grid in a previous area explored in September 2011, and to determine if the soil temperatures proved the source to be larger than its current surficial exposure. The additional area, Area 2, was studied to investigate the anomalies observed during the May 2012 Forward Looking Infrared (FLIR) investigation. A FLIR survey was conducted in May 2012. The camera indicated via color strips temperature of surfaces. 6.2.2 Selective Extraction Geochemical Analysis A selective extraction geochemical study of a select area near the hot springs was conducted. The selective extraction geochemical study consisted of obtaining samples from the B soil horizon and conducting Enzyme Leach and Terrasol selective digestion on the soil sample. The method relies on the fact that geothermal systems, like mineral deposits, have at the surface a number of elements that get distributed around the Tenakee Inlet Reconnaissance 11 HDI rae eva tnen, Engineering Consultants margins of the system. Trace elements can be trapped in amorphous oxide coatings on sand and silt grains in soil near the surface. Enzyme leach and Terrasol digest these coatings and releases the trapped trace elements. An analysis of the sample is conducted for up to 68 trace and major elements by ICP-Mass Spectrometry. The concentrations of these elements are mapped and distinct patterns indicate areas of interest. Sampling consisted of using a clean spoon to obtain soil from a hole excavated below the organic layers. Care was taken to maintain clean spoons and sampling equipment. The shovel used to sample was wiped clean after each sample and pushed into the immediate soils several time to help eliminate cross-contamination from a prior sample. An approximately 25 gram sample collected using a stainless steel table spoon was placed in a 50 ml plastic tube that was supplied by the laboratory. The samples were typically fine-grain. Care was taken to avoid and/or eliminate particles larger than about coarse sand. Of the 63 soils sample collected 27 duplicate samples were taken at select areas and two samples were collected at random locations outside of the geothermal area. 6.2.3 Water Sampling Water samples were collected for chemical analysis from the hot springs, and Tenakee Creek. Additional samples were collected upstream and downstream of the hot spring location and from the two boundary streams. Water samples were also collected from the springs every couple of days to evaluate if there was a change. Temperature, pH, and conductivity were collected on-site at each sampling location. Sampling consisted of collecting approximately 800 ml of water over several bottles supplied by the laboratory. The bottles were washed using the fluid to be collected. The water was filtered if it appeared to be cloudy. The majority of the samples were not filtered due to the clear nature of the water. In addition to the water samples collected for chemical analysis, additional 25 ml samples were collected at select locations for isotope analysis. 6.2.4 Rock Sampling Geological strata, rock units, and surface layers were mapped. Outcrops were difficult to find due to the vegetation and accessible outcrops were even more difficult. Many outcrops occurred as steeply dipping walls forming river valleys and were not accessible. Geochemical alteration was minor and was not mapped due again to the vegetation (Figures 8a through 8b). Where accessible outcrops were sampled and the strike and dip were obtained of features such as bedding planes, joints, and faults. 6.3 Instrumentation Two LevelTROLL’s were successfully installed in Tenakee Creek and the outflow of the main hot spring in order to record water levels. During our May 21, 2012 visit we noticed that the LevelTROLL installed in the hot springs had been removed and there was no trace of the instrument. Tenakee Inlet Reconnaissance 12 HIDID aeercoueys unser Engineering Consultants To protect the LevelTROLL installed in Tenakee Creek from damage it was contained within a perforated 1-1/4” x 12” galvanized metal pipe with threaded end caps. Perforations in the pipe allowed for accurate pressure readings. The pipe is fixed to a concrete block using 1-5/8” galvanized tension bands connected to 5/16” stainless steel carriage bolts embedded within the 65 pound concrete block. The block was cored through the center to allow a stick of No. 4 reinforcing steel (rebar) to be inserted through the block. The rebar was drove approximately two feet into the streambed and bent downstream to prevent movement of the block and allow passage of debris floating in the creek. At the hot spring location the LevelTROLL was installed within a perforated 3/4” x 12” galvanized metal pipe with threaded end caps. Two No. 4 rebar sticks were drove into the surface and the galvanized metal pipe containing the LevelTROLL was fixed to the rebar using rebar tie wire. Due to the high temperature of the water an external battery pack was connected to the LevelTROLL to extend the length of data collection. 6.4 Tenakee Creek Cross Section Data 6.4.1 Cross Section Data —- May 2012 Tenakee Creek was surveyed along the cross-section where the LevelTROLL was installed. The deep snow pack at the edge of flowing water prevented surveying the cross-section beyond the current flowing stream width (i.e. the high water mark could not be surveyed). Based on field measurements at the LevelTROLL installation location the approximate flow rate of Tenakee Creek was 26.1 ft?/sec or 11,724 gallons/minute (gpm). The cross-section at the hot spring LevelTROLL installation has a bottom width of nine inches, top width of 12 inches and average depth of 2.25 inches for an area of 0.164 ft”. The velocity was measured with a result of 0.36 ft/sec, corresponding to a calculated flow rate of 0.059 ft?/sec or 26.5 gpm. 6.4.2 Cross Section Data —- September 2012 Three stream cross section surveys, A, B, and C, were completed to evaluate the stream section and aid in calculating creek flow using the pressure transducer data. The Tenakee Creek Cross Section Figures for surveys A, B, and C are presented in Figures 9a, 9b, and 9c respectively. Surveyed points were collected every five feet through the section and at significant locations (high water level, current water level, the thalweg, and pressure transducer location). Flow measurements using a Marsh McBirney Flo- Mate 2000 Portable Flowmeter were collected. A summary sheet of the measured flow data for Cross Sections A, B, and C is presented in Figures 9a through 9c. The Tenakee Creek pressure transducer was downloaded on August 20, 2012 and reinstalled in the creek for continued monitoring. The Tenakee Creek Monitoring graph Tenakee Inlet Reconnaissance 13 Hea Engineering Consultants for February 2012 through August 2012 is presented in Figure 10. The stream survey data combined with the pressure transducer data was analyzed to estimate a monthly high and low flow of Tenakee Creek. The flow was calculated using Manning’s equation. The monthly high and low flow calculations are presented in Table 6. Ice in the stream affected the pressure transducer during low flow periods in March and April resulting in zero flow. Table 6: Tenakee Creek Flow in Gallons per minute (gpm) High 175 2437 5351 6666 8690 8718 Low - - 1272 2380 2212 2870 6.5 Assessing Wintertime Conditions The snowpack was assessed at the site during March 7, 2012. An eight-foot long probe was used to determine snow depth at the helicopter landing zone but the probe was not long enough to reach the ground surface. In general snow depth appeared to be distributed evenly when not influenced by large spruce trees or the hot springs. The undergrowth (alder, devils club, etc.) was completely covered by the dense snowpack. No evidence of avalanche activity was observed in the immediate vicinity of the project area during March 7, 2012. In February 2013, the snowpack appeared to be similar in thickness however there had been several small earthquakes in the area and small avalanches were noted along the stream bank and near the hot springs. Along the upper portion of the main hot spring stream the snowpack forms near vertical walls along the edges of the free flowing stream that are greater than six feet in depth in most locations. From previous site visits we know this stream is approximately 400 feet long and terminates at Tenakee Creek. Approximately 300 feet of the stream was free of snow cover. 6.6 Shallow Test Pits on Hot Spring Island Three shallow test pits were hand dug to determine if groundwater flowed from the hot spring source to the ‘seeps’ near the river. Test Pits TP-1, TP-2, and TP-3 were hand dug to 22 inches, 19 inches, and 22 inches, respectively. Cobbles and loose sands did not allow for the test pits to be excavated beyond the depths explored. No groundwater was encountered during the field investigation. Soil temperatures of 108°F, 106°F, and 102°F were measured in Test Pit TP-1, TP-2, and TP-3, respectively. 6.7. Laboratory Analysis Different laboratories were used depending upon the nature of the material submitted. Appendices A and B contain the results of the laboratory testing. For the soil samples, Skyline/Actlabs of Tucson Arizona was used. The water samples were submitted to WetLab of Nevada for analysis of the cations/anions, and geothermometer components and to Southern Methodist University in Texas for isotope analysis. Tenakee Inlet Reconnaissance 14 HID reer nee Engineering Consultants A selective extraction process termed enhanced enzyme leach was used at Skyline Laboratories on the soil samples. The enhanced enzyme leach process is a proprietary technique used to mainly identify mineral deposits. Trace elements become trapped within amorphous oxide coatings on sand and silt grains in soil and sediment in the near-surface environment. The process analyzes 68 trace and major elements by ICP- Mass Spectrometry. The detection limits are typically on ppb levels with a few elements at the ppm level. Isotope analysis was conducted by the Stable Isotope Laboratory at Southern Methodist University. Oxygen and hydrogen isotope analysis were conducted for each sample. Every fifth sample is repeated as a standard used by the laboratory. Water samples were analyzed for the following parameters using the methodology listed. Table 7: Parameters tested in the water samples PARAMETER nes EPA METHOD : ——— a (unless noted).

For the shallow temperature survey, temperatures measurements were repeated at select location. In general an effort was made to resample at a rate of approximately 20 percent. Due to the scarcity Tenakee Inlet Reconnaissance 15 HDD ipareues UINNELL Engineering Consultants and type of data obtained from the rock samples, only one sample was collected at each location. The water samples were received by WETLAB in good condition however the holding time for sulfide had expired. Silica concentrations were obtained by two different methods. The difference in these concentrations was between 0 to 5 percent for the hot spring samples but on the order of 20 to 30 percent for the surface water samples. This appears to be due to the low concentrations measured in the surface water samples. The concentrations were higher in the hot springs sample and therefore the difference in laboratory analysis was much less. Typically the colorimetric values were higher than the EPA 200.7 method. Duplicate water samples had a standard error of typically less than 10 percent for all species tested. Many of the species tested, the duplicates had a O percent standard error. SiO2 (silica) for the surface water samples had a standard error of 14 and 28 percent for the two duplicate samples. Other chemical species standard error for these duplicate samples was less than 10 percent with many being 0 percent. Nineteen of the 68 soils trace and major elements have average standard error above 100 percent. The remaining elements generally have a standard error below 40 percent. Except gold (Au), uranium (U), magnesium (Mg), potassium (K), and iron (Fe) the remaining 19 elements generally have low concentrations in soils and therefore the standard error would be anticipated to be large. A standard error of 40 percent or less is acceptable given sampling non-homogenous materials. 7.2 Temperature The shallow temperature data obtained is presented in Figures 11a through 11c. It can be seen that the hottest temperatures occurred near the hot springs and at the seeps found at the edge of Tenakee Creek. Temperatures near the hot spring range from 81.2°F to 108.9°F. The outflow from the hot springs had temperatures in the soil of between 58.3 and 86.1°F. Seeps were observed when the water level in Tenakee Creek was lowered during a few days of no rain. The one seep had a nearby soil temperature of 130.5°F. Temperatures on the hillside above the spring ranged from 49.9°F to 46.4°F. A relatively cool temperature of 44.3°F was obtained upstream of the hot springs located near the edge of the gravel bar that hosts the hot springs. Additional temperatures above background (46.5°F) were encountered at several spots across Tenakee Creek at the base of the slope. The hottest temperature that occurred across the creek from the hot springs was 88.8°F and another point at 59.5°F. There were several points across the creek above 50°F with one (56.5°F) occurring about 1,200 feet downstream of the hot springs. These temperatures do not appear to be the result of outflow from the hot springs. The temperature of the water in Tenakee Creek was approximately 40°F to 45°F. Tenakee Inlet Reconnaissance 16 WIDIL ares cue sun Engineerii ing Consultants In Area 2 (Figure 11c), the shallow temperatures ranged from 35°F to 52°F. These temperatures not appear to be indicative of a larger geothermal system outside the original study area or indicative of a secondary geothermal resource. 7.3 FLIR Camera Results A field trip was performed on May 21, 2012 to evaluate the study area with a handheld FLIR Camera. The hot springs, seeps, and potential downriver heat signatures were identified from the helicopter. A FLIR Camera Map is presented in Figure 12. 7.4 Water The average concentrations for the hot spring water samples, the seeps water samples and the surface water samples were calculated. Table 8 presents the average concentrations for this group of samples. The temperature of the hot springs averaged 170°F (76.8°C) with Hot Spring #1 having the hottest measured temperature of 177°F on two sampling events and Hot Spring #4 having the coldest measured temperatures of 161°F and 163°F on three sampling events. The average temperature for Hot Springs #1 through #3 was 172°F. The average surface water temperature was 40°F (4.7°C). The difference in between the hot springs and the surface water temperature is 130°F. Lithium and magnesium concentrations were below the detection limit for all three sets of samples. The charge balance on each sample was typically five percent or less with 22 of the samples having a charge balance of two percent or less. Appendix A presents the detailed water analysis. The average concentrations of the species indicate that the seeps appear to be more related to the hot springs than to the surface waters. The values for the average concentrations for the seeps are closer to the hot spring averages than the surface waters.

Geothermometers are calculated and ternary plots are produced.

This is important in that the two waters clearly represent separate types of fluids. The often used Cl-SO,-HCO3 ternary plot illustrates the amounts of major anions present in geothermal waters (Figure 13a). This plot indicates that the hot spring waters are low in chlorine (Cl) and bicarbonate (HCO3) and high in sulfate (SO). This plot indicates that the hot spring waters are associated with the volcanic waters and perhaps heated by steam from a deeper reservoir. A high sulfate spring is typically associated with deeper boiling zones. The isotope plot in Figure 13b indicates that both the hot springs waters and surface waters are primarily meteoric and have not mixed with other fluids. The quartz/chalcedony solubility curve also in Figure 13b indicates based on the silica, potassium/magnesium concentrations that the chalcedony geothermometer will provide a more accurate temperature for the hot spring fluid at depth. Based on the chalcedony geothermometer the hot spring fluids have been heated to 260°F. Many of the hot spring samples have a chalcedony geothermometer of between 217°F to 241°F. 7.5 Soil The soil chemistry was summarized and plotted in Figure 14. These chemical species had orders of magnitude changes in the concentrations of that particular species across the sampling area. Concentrations were contoured using roughly the standard deviation in a particular elements concentration. These contour maps and laboratory data are provided in Appendix B. The following species were plotted: Arsenic (As), Cobalt (Co), Gold (Au), Manganese (Mn), Titanium (Ti), and Vanadium (V). Mercury is usually a chemical species that is measured in geothermal exploration. The mercury that occurred in the samples obtained did not indicate a large variation in concentration and therefore we did not plot this element. Tenakee Inlet Reconnaissance 19 HID Aree oer sine Engineering Consultants The species plotted indicated anomalous concentrations generally near the hot springs and along the outflow but also across the river where there were higher then background soil temperatures. The highest concentration of gold was near the confluence of the hot spring outflow and Tenakee Creek. The highest concentration for arsenic was across the river from the hot springs at the grid point that recorded the highest temperature on that side of the river. In addition, vanadium had higher concentrations along the ridge above the hot springs perhaps indicating a fracture location along this ridge. 7.6 CO2 Gas Survey The carbon dioxide (CO2) gas survey consisted of collecting soil gases at a number of locations near both the hot springs and across the creek. Carbon dioxide gas is typically associated with geothermal systems and faults that leak the gas upwards. Twenty gas samples were collected (Figure 15). Four of the samples had carbon dioxide concentrations on the order of 10,000 parts per million or greater with the highest concentration of 16,100 parts per million. The remaining samples had carbon dioxide concentrations ranging from 643 to 8,650 parts per million. Three of the four high concentrations occurred along the base of the bluff on the northwest side of creek across the creek from the hot springs. The fourth high concentration occurred near the hot springs. The CO2 laboratory data is presented in Appendix C. 7.7 Lineations Figure 16 presents the results of our lineation study. Lineations were determined from stereographic aerial photographs. The lineations may represent faults or joints. The lineations were not observed on the ground due to the extensive vegetation however during the helicopter flights over the area, many of the lineations could be seen on a regional scale. The lineations are typically aligned northwesterly with some cross lineations. This alignment is typical over the entire southeast region and is due to the large Queen Charlotte-Fairweather fault system and tectonics of the region. Particularly interesting is the offset in Tenakee Creek near the hot spring location. There is a set of lineations that occur northwest and the creek is offset on lineations that occur east to west. Table 10 presents the strike and dip of lineations measured in the field and taken from the geological map referenced in Figure 5. The measurements indicated steeply dipping lineations and the northwesterly strike and the cross-set.

These thermal areas would suggest that the geothermal source is larger than just the known four hot springs. The occurrence of chemical anomalies in the soil in the hotter areas across Tenakee Creek also suggests that the hot fluids are circulating near the surface indicating permeability. The lineations and general tectonics of the region suggest that the hot springs were developed due to the wrenching of the cross cutting lineations near the hot springs Tenakee Inlet Reconnaissance 22 HOD eerie Engineering Consultants which led to the fracturing of the rocks. Also given the high angle nature of many of the lineations, it is reasonable to assume that high angle faults bring the geothermal fluid to/near the surface. The earthquake data suggest that the study area is tectonically active and that the igneous intrusives are permeable. Based on the water chemistry, the hot springs fluids are most likely associated with volcanic waters and perhaps heated by steam from a deeper reservoir. The chalcedony geothermometer indicates that the hot spring fluids have encountered temperatures on the order of 260°F. The average surface temperature of the hot spring waters is 170°F. These surface and subsurface temperatures are in the range that binary geothermal power plants operate. Much like Chena the site benefits from having cool waters at approximately 40°F as a cold sink. The geochemical analysis of the spring has yielded a possible maximum temperature of the source water at a depth of 260°F (127°C). Based on our reconnaissance efforts we have developed the conceptual model of the resource shown in Figure 17. The upper limit on isotherm values is the boiling point of water versus depth. The minimum depth for 260°F (127°C) would be fairly shallow at less than couple of hundred feet. Depending upon the localized geothermal gradient the 260°F could occur at a deeper depth. A temperature gradient reported by Economides in 1982 for the separate resource (investigated by shallow wells) approximately 30 miles away at Tenakee Springs indicates a temperature gradient of 13°C/100 feet. If we assume a similar gradient with surface temperatures at about 45°F (7°C), then at the same gradient, the temperature of 260°F (127°C) would be reached in less than 1,000 feet. This is probably over optimistic; however it suggests a shallower resource rather than a deep resource. The Queen Charlotte/Fairweather fault system is a major transform plate boundary with high angle faults that cut through the crust. The Cretaceous igneous rocks provided heat during their emplacements and are still cooling as indicated by high heat flows in the region (Blackwell and Richards, 2004). The heat source is not a typical magma body as seen in places like Akutan or Mount Spurr but rather hotter deeper fluids associated with deep crustal materials. A high angle fault has allowed for the hotter, deeper waters to move upward creating the hot springs. The hot spots occur due to splays in the primary fault that either reach the surface (the case of the seeps) or come close to the surface (the hot zone across the creek). The carbon dioxide results seem to suggest faults that connect to the deeper system across the creek from the hot springs. Tenakee Creek as a source of cold water may cool the system near the surface but does not appear at this point to cool the overall system. There does not seem to be a significant change in the flow regime of Tenakee Creek downstream of the resource compared to upstream of the resource. The outflow of the system is downstream towards the north following the general strike of the lineaments in the region and along the creek.

Resource agency interviews were not conducted. However, resource agency interviews will be completed when a baseline overview of environmental resources is developed in support of future National Environmental Policy Act (NEPA) documentation for the project.

The process also requires that environmental information is available to public officials and citizens before decisions are made and actions to develop a project are taken (Figure 18). In 2008 the Bureau of Land Management (BLM) and USFS completed a Programmatic Environmental Impact Statement (PEIS) for Geothermal Leasing in the Western United States. The PEIS addresses geothermal potential in twelve western states, including Alaska. The PEIS is regional in scope and supports a broad-scale analysis based on foreseeable on-the- ground actions, including exploration, drilling, and utilization, which are not analyzed site-specifically, but are analyzed for planning area based scenarios only. According to the PEIS, The Energy Policy Act of 2005 designated one of the project’s goals as “... [to] facilitate geothermal leasing decisions on...future lease applications...on federal mineral estate...” (BLM & USFS 2008). National Forest Lands designated by the PEIS as lands in geothermal potential area include the project area and most of Chichagof Island. The Programmatic EIS is considered a first-tier NEPA document. A project-level NEPA document or second-tier NEPA document would need to be completed to addressed site specific direct and indirect environmental impacts related to the proposed development's specific scope of work. A second-tier EIS would likely be required for this project. The EIS would document potential impacts to the natural and man-made environment, including short-term construction impacts, permanent (long-term) impacts related to the proposed project and any reasonably foreseeable future actions, and both secondary and cumulative impacts that might result from this project. The EIS would also document how issues raised during public and agency scoping were address, and propose mitigation measures that would avoid or minimize environmental impacts 10.0 FEDERAL AND STATE PERMITS, LICENSES, AND APPROVALS Table 12 lists potential permits required by federal and state agencies to conduct exploratory drilling at the geothermal resource. Table 13 describes potential permits and authorizations required to construct and operate a geothermal power production facility, develop associated access roads, and establish power transmission lines. Additional permits and authorizations may be identified during the agency scoping process.

Each depends upon two main factors within the geothermal source. The first is the temperature of the source and second is the flow of the well. The higher the water temperature and flow, the more energy the source can produce. The inverse is also true. When selecting a power plant for a geothermal source, temperature and flow are the deciding factors. The four types of geothermal power plants that harness the energy from the geothermal source are dry steam plants, flash power plants, flash/binary and binary plants (Kagel). Dry steam power plants make use of the direct flow of the geothermal steam, whereas a flash plant uses liquid water and steam to product electric power. Dry steam plants use steam produced directly from the geothermal reservoir to run turbines that power generators. This is the simplest method of geothermal power production, but the downside of a flash power plant is that the water temperatures are required to be between 350-500°F (Kagel). The modern integrated flash power plant called Combined Cycle Unit (GCCU) manufactured by ORMAT, “are designed to generate power from high-pressure geothermal steam sources” (ORMAT). This unit requires that the source temperature be hot enough to produce steam on its own (>300°F). The GCCU takes the steam directly from the source and puts it into a steam turbine which generates power. The waste steam is recycled and goes into a heat exchanger that heats an organic fluid (low boiling point). Once the fluid is heated, it is then sent into an Organic Turbine where it produces more power. The remaining geothermal water is then cooled and pumped back into the geothermal source using an injection well (ORMAT). The final method of geothermal power production is called Binary. This method uses the Organic Rankine cycle which “is a thermodynamic process where heat is transferred to a fluid at a constant pressure. The fluid is vaporized and then expanded in a vapor turbine that drives a generator, producing electricity” (ORMAT). The Organic Rankine Cycle uses an organic fluid that has a lower boiling point than water. The geothermal water comes into non-direct contact with the fluid in a heat exchanger, where the organic fluid is turned into steam to power a turbine (ORMAT). The used geothermal water is then pumped back into the source thru an injection well. 12.0 DEVELOPMENT OPTIONS Many geothermal power plants can be remotely operated with occasional visits by technicians. The ADOT&PF is evaluating the construction of a road from Hoonah to Pelican. If this road was to be constructed prior to the development of this project it would significantly change the cost of the transmission line and/or pipeline considered here. In the preparation of the capital costs we have assumed that the road would have to be funded and built under this project, but we have used existing roads to the extent Tenakee Inlet Reconnaissance 28 DD rere ner sume, Engineering Consultants practical. Construction access can occur from Tenakee Inlet with a minimal construction access road from a barge landing area to the site. There are five proposed power plant sites with two different transmission alignments. In all options the well field is located near the hot springs within the Tenakee Creek valley. Figures 19 and 20 present the sites and transmission alignments. The transmission alignments would also be the alignments for the access road. Transmission Line Alignments: e BLUE - consists of 34 miles of transmission line and access road: 19.2 miles is along existing roads and 14.8 miles in roadless areas. The BLUE alignment follows the roads to Game Creek and then heads west towards Salt Lake Bay site along a cliff above the ocean. The alignment then crosses the hills to Tenakee Inlet and then along the inlet pass Port Fredrick to the head of the inlet and Tenakee Creek valley. e YELLOW - consists of 33 miles of transmission line and access road: 18.2 miles is along existing roads and 14.8 miles in roadless areas. The main difference with the YELLOW alignment is at Game Creek the road crosses through a pass to Salt Lake Bay. The route to Tenakee Creek valley is the same as the BLUE alignment. Power Plant Sites: A) A power plant located at Port Fredrick, with pipeline to the well field B) A power plant located at Salt Lake Bay with pipeline to the well field C) Three locations for the power plant within the Tenakee Stream valley C1) the power plant located above the well field on the west side of the stream valley C2) the power plant located above the hot springs and well field on the southeast side of the stream valley C3) the power plant located northeast of the well field on the west side of the stream valley along a large gravel bar. 12.1 Estimated Costs The costs for the five sites (A, B, C1, C2, and C3) shown in Table 14 include the power plant, site work, local piping, four production wells, mob/demob of construction equipment, and construction access road. Costs for generators and specialized electric equipment are highly dependent upon the temperature, pressure, and nature of the brine. The costs for the two transmission alignments shown in Table 15 were prepared with different costs for segments along roads and segments in roadless areas. Substations are included in the costs. Costs in both tables include design and construction management fees and 10 percent contingency. Detail cost estimates are presented in Appendix D and the preliminary economic analysis report. Tenakee Inlet Reconnaissance 29 HOD perceives Engineering Consultants Table 1s: Estimated Capital Costs for eee aca Option A Option B Option C1 Option C2 Option C3 Based on the estimated capital costs Option C3 located on the gravel bar in the stream valley is the least expensive option. Option C2 located on a hill above the hot springs is the most expensive option. The difference in cost between C1, C2, and C3 is due to site development. Site C2 is the most rugged of the three sites in the valley while Site C3 is the most level. Site B (Salt Lake Bay) is the next lowest cost alternative due to accessibility and also site development costs are lower compared to Site A (Port Fredrick) or C2. Table 15: Estimated Costs for Transmission from the different sites. “TRANSMISSION AL ALTERNATIVE : __|__ ESTIMATED TOTAL COSTS SITE "A" ROUTE Power Transmission Route BLUE w/ pipeline $26.4M Power Transmission Route YELLOW w/pipeline $25.7M SITE "B" ROUTE Power Transmission Route BLUE w/pipeline $21.3M Power Transmission Route YELLOW w/pipeline $20.7M SITE ""C" ROUTE Power Transmission Route BLUE $28.1M Power Transmission Route YELLOW $27.5M Two options have a total cost of $49M: Options Site C3 and Yellow transmission route or Site B and Yellow transmission route. Site C3 is the least expensive option in terms of site development whereas Site B is the least expensive in terms of transmission. The option with the highest cost was Site C2 following the BLUE route at $63.3M. 13.0 BENEFIT-COST RATIO Based on the analysis conducted by Northern Economics (NEI) the following benefit-cost (B/C) ratios were determined. Tenakee Inlet Reconnaissance 30 HO eS Table 16: Benefit-Cost Ratio Summary PROJECT 50-year lifespan | 30-year life span 20-year life span Geothermal 0.93 0.47 0.31 The differences between the engineer’s B/C and the AEA B/C analysis are due to AEA's analysis uses a shorter lifespan (20 years versus 50 years). In addition, fuel projections also affect the benefit-cost ratio. The AEA analysis uses fuel projections calculated by the University of Alaska's Institute of Social and Economic Research (ISER). The Engineer's analysis used IPEC's actual fuel prices from 2012 and extrapolating to future fuel costs based on compound annual growth rate derived from ISER fuel projections. The impact from the Gartina Falls project is also accounted in the 20 and 30 year analyses. A sensitivity analysis was conducted using Monte Carlo simulation techniques to evaluate uncertainties in selected variables. A simulation using 5,000 iterations was conducted to understand significant variables and the likely range of benefit-cost ratios. Key input variables were capital costs and fuel prices. Using probabilistic-variations in capital costs and fuel prices, the analysis concluded that a benefit-cost ratio greater than one would occur approximately 12 percent of the time with a mean benefit-cost ratio of approximately 0.83. 14.0 FOLLOW-ON WORK The reconnaissance work conducted and reported in this report is the first step in the exploration of this resource. There are several positive signs to continue to explore this resource. This includes the location of the resource, the larger size than anticipated, the fluid temperatures obtained from the geochemistry, the presences of active faulting, and the inferred fault that allows for the resource to exist. We did not know depth of production fluids, permeability of the rocks at depth, fluid flow at depth, overall heat capacity of the resource, and overall size of the resource. Follow-on work for this project would be to conduct a geophysical survey and a robust exploratory drilling project. The geophysical survey would assist in siting the exploratory wells. The moderate temperature of the resource precludes the use of the standard magneto- telluric (MT) geophysical method. The MT method generally identifies a clay cap on the top of a geothermal resource. The clay caps generally develops in high temperature resources. Other geophysical methods have also been precluded due to the rugged terrain and lack of accessibility. Seismic and electro-magnetic methods generally require some open areas for the equipment. Seismic methods may be useful at this site Tenakee Inlet Reconnaissance 31 AD irene uersue Engineering Consultants to identify fault zones and overall structure and would be the first choice depending upon funding levels. Reflection seismic surveys are typically used to explore deeper and larger resources. It may be feasible to conduct seismic refraction studies to obtain a better understanding of the near surface environment (100 to 300 feet). A SP (self- potential) survey may also prove useful if conducted during quiet water periods. The SP survey would provide information on depth of water and possible location of geothermal fluids. Tenakee Creek is an active creek and may mask the signal from the geothermal source. In lieu of conducting one to two deep exploratory drill holes in select locations, shallow drill holes in multiple locations could be conducted. Currently the depth of exploration at the site is approximately 5 feet by the shallow temperature probes. The next step would be to conduct shallow (less than 1,000 feet) drilling. This would allow for acquisition of geothermal gradient data, perhaps permeability data, additional fluid chemistry data, and a better understanding of the geological structure, the size and heat capacity of the resource. We would propose to conduct drilling at 3 to 5 locations including near the hot springs, near the hot spot across Tenakee Creek, and one to two additional holes downstream to the north of the hot springs. These holes would all be drilled in the valley bottom and be helicopter supported. Once on the gravel bar across the creek from the hot springs, the rig maybe able to move around on a track mount. Tree cutting would be needed. One to two deeper holes could be conducted instead of the shallow holes. These drill holes would be located at the hot springs and at the hot spot across the creek. The holes would be drilled to depths of 4,000 to 5,000 feet. Permitting would be required for all of these activities and coordination with the US Forest Service would be needed. The permitting by the Forest Service and other agencies would require most of a winter to achieve prior to conducting the drilling in the summer months. The geophysical survey may be conducted in early summer once the snow has melted. After this exploratory phase additional exploratory drilling may be needed to determine where the production wells should be placed. Given the size of the resource this may not be necessary since there is limited areas to place a well. Depth to the resource may still be in question after the initial drilling however, there would be more of a constraint based on the acquired geothermal gradients. 15.0 CONCLUSIONS & LIMITATIONS The analyses contained in this report is based on the fieldwork conducted to the date of the report. Additional field work may cause the assumptions in this report to be invalid and change the project costs and anticipated development scenarios. This was a reconnaissance level effort and should be understood to be the first step in Tenakee Inlet Reconnaissance 32 PAD rere ber a uimen, Engineering Consultants understanding this geothermal resource. Additional field work should be anticipated prior to drilling a production well. PREPARED BY: HATTENBURG DILLEY & LINNELL,LLC Lorie M.

The analytical data and information contained therein was generated using specified or selected methods contained in references, such as Standard Methods for the Examination of Water and Wastewater, 18th & 19th editions, Methods for Determination of Organic Compounds in Drinking Water, EPA-600/4-79-020, and Test Methods for Evaluation of Solid Waste, Physical/Chemical Methods (SW846) Third Edition. The samples were received by WETLAB-Westem Environmental Testing Laboratory in good condition on 10/5/2011. Additional comments are located on page 2 of this report. If you should have any questions or comments regarding this report, please do not hesitate to call. Sincerely, Andy Smith QA Manager Page | of 13 Western Environmental Testing Laboratory Report Comments Hattenburg Dilley & Linnell - 1110060 General Comments The samples were received by WETLAB-Westcm Environmental Testing Laboratory on 10/5/2011. By this time, the EPA recommended holding time for Sulfide had expired. The analysis was performed on ajt submitted samples upon receipt past the holding time per client's request. Specific Comments None Data Ouslifier Leeend B — Blank contamination; Analyte detected above the method reporting limit in an associated blank HT == Sample held beyond the accepted holding time J ~— The reported value is between the laboratory method detection limit and the laboratory practical quantitation limit M — Reported value is estimated; The sample matrix interfered with the analysis N ~ There was insufficient sample available to perform a spike and/or duplicate on this analytical batch. NC = — Not calculated duc to matrix interference Q ~— Reported value is estimated; The value failed to meet QC criteria for either precision or accuracy SC — Spike recovery not calculated. Sample concentration >4X the spike amount; therefore, the spike could pot be sdequatcly recovered. 475 Bast Greg Stroet Suite #119, Sparks, NV 89431 (775) 355-0202 Page 2 of 13 - ELAP No: 2523 - EPA Lab ID: NV00925 -

Sincerely, Andy Smith QA Manager Page | of 20 Western Environmental Testing Laboratory Report Comments Hattenburg Dilley & Linnell - 1110199 General Comments The samples were received by WETLAB-Westem Environmental Testing Laboratory on 10/3/2011. By this time, the BPA recommended. holding time for Sulfide bad expired. The analysis was performed on all submitted samples upon receipt past the holding time per client’s Tequest. Specific Comments Due to the sample matrix it was necessary to analyze the following at a dibution: 1110199-008,010,015,016,018,020 Iron The reporting limits have been adjusted accordingly. Data Oualifier Legend B — Blank contamination; Analyte detected above the method reporting limit io an associated blank HT — Sample held beyond the accepted holding time J — The reported value is between the laboratory method detection limit and the laboratory practical quantitation limit M — Reported value is estimated; The sample matrix interfered with the analysis N — There was insufficient sample available to perform a spike and/or duplicate on this analytical batch. NC = Not calculated due to matrix interference Q — Reported value is estimated; The value failed to meet QC criteria for either precision or accuracy SC = Spike recovery not calculated. Sample concentration >4X the spike amount; therefore, the spike could not be adequately recovered. 475 Bast Greg Street Suite #119, Sparks, NV 8943) (775) 355-0202 Page 2 of 20 + ELAP No: 2523 - EPA Lab ID: NV00925 -
