Tenakee Inlet Geothermal Reconnaissance
Preliminary Environmental Overview July 3, 2013
INTRODUCTION
Hattenburg Dilley & Linnell (HDL) has been contracted by the Inside Passage Electric Cooperative (IPEC)
to conduct subsurface exploration of a known geothermal resource near Tenakee Inlet in southeast
Alaska on Chichagof Island. The study was funded by Alaska Energy Authority Renewable Energy Grant
#7040073 and is currently scheduled for completion in June 2013. The purpose of the study is to identify
whether the resource holds enough energy to supply power to the communities of Hoonah and Pelican.
If the study shows the resource could provide enough power to offset rising costs and energy demands
within the local communities there is potential to develop a geothermal power plant and associated
infrastructure needed to access the site and distribute power. The project is located within the Tongass
National Forest at the head of Tenakee Inlet at 57° 59’ 24” North Latitude and 135° 56’ 20” West
Longitude in Southeast Alaska. The springs at Tenakee Inlet are located approximately 10 miles from
Pelican, 20 miles from Hoonah, and 30 miles from Tenakee Springs (Figure 1).
The purpose of this report is to review existing environmental information for the area surrounding the
proposed location of development to identify natural resources that could potentially be affected by the
proposed project. In addition, this report identifies likely agency permits and authorizations needed to
develop the project.

Exploratory Drilling
A reconnaissance study of the subsurface geothermal resource was conducted in 2011 and 2012 and
revealed water temperatures between 240 °Fahrenheit (F) and 260 °F, which is considered within the
operational range of binary power plants (Figure 2). To further investigate the potential of the hot
springs to produce electricity, two to four exploratory drill holes to depths of 3,000 to 4,000 feet below
the ground surface are needed.

Access
Accessing the site would likely require a barge landing and an access road (Figure 3). Preliminary
assessment of site access has been based primarily on terrain surrounding the proposed development
site. Currently there are two possible barge landing sites located on the west side of Tenakee Inlet.
There are three potential road routes that would lead to the geothermal site from the barge landing or
by connecting existing Forest Service access roads; and a fourth option constructing a new road from
Port Frederick to the site. Potential road routes to the site range between two and three miles long.
Since the reconnaissance project began, Southeast Region Alaska Department of Transportation &
Public Facilities (ADOT&PF) is revisiting possible development of a proposed road connecting the
communities of Hoonah and Pelican. Development of the resource may support ADOT&PF's plans for
the road, which would pass within a few miles of the geothermal site.

Geothermal Power Plant
If the geothermal resource proves to hold sufficient energy to provide power, development of a five
megawatt (MW) geothermal power plant facility would be proposed. The project would involve
installation of
e two to five geothermal wells;
e piping to bring fluids to the power plant;
e roads and a barge landing for access; and
e atransmission line to transmit power to the communities of Hoonah and Pelican.
Under the current conceptual design, the development would require approximately eight acres of land
for both the power plant (5 acres) and associated well field (3 acres). The project would focus on the
4 “\ HATTENBURG DILLEY & LINNELL Engineering Consultants

minimum land area needed to construct the production facility, which would serve the communities of
Hoonah and Pelican.
Power Transmission
A transmission line would be constructed from the geothermal power plant to the communities of
Hoonah and Pelican. Current considerations of distribution line locations include:
e Along existing forest service roads
e Along existing transmission line corridors
e Along the potential power transmission corridor identified in the Tongass Land and Resource
Management Plan (Figure 4)
The transmission line corridor is estimated to be approximately 20 miles long to Hoonah and ten miles
long to Pelican. All potential transmission line route alternatives leading from the geothermal power
plant include an underwater cable (submarine transmission line) across upper Tenakee Inlet (shown in
Figure 3).

PRELIMINARY ENVIRONMENTAL RESOURCES
The summaries provided for the resource categories below is a result of research conducted of existing
and readily available information from state and federal resource agencies. Resource agency interviews
were not conducted in association with producing this report. 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.
‘) HATTENBURG DILLEY & LINNELL
Tenakee Inlet Geothermal Reconnaissance
Preliminary Environmental Overview July 3, 2013
Cultural, Historical, and Archaeological Resources
The National Historic Preservation Act of 1966, as amended (16 United States Code [U.S.C.] 470) is the
primary law governing the preservation of cultural resources in the United States (U.S.) (National Trust
for Historic Preservation [NTHP], 2011). The Act requires any project funded, licensed, permitted, or
assisted by the federal government be reviewed for impacts on significant historic properties. Such
projects are required to complete the Section 106 consultation process to take into consideration
actions that could adversely affect historic properties listed, or eligible for listing, on the National
Register of Historic Places (National Register).
HDL has subcontracted with professionals who meet the Secretary of the Interior’s Professional
Qualifications to conduct a literature review and research the Alaska Heritage Resource Survey (AHRS)
files for known historic properties and studies conducted in the area of the proposed project. Results of
the AHRS review and previous research is presented below.
Port Frederick Village (“Portage”) is located at the narrow portage between the head of Tenakee Inlet
and the western end of Port Frederick on Chichagof Island. This site was determined eligible for listing
on the National Register in 1994. In or near the powerline corridor at Salt Lake Bay are the Salt Lake Bay
Bridge and Road Complex (JUN-435), the South Salt Lake Bay Hunting Blind (SIT-439) and a cabin
platform (SIT-676). The Salt Lake Bay Bridge and Road Complex are believed to be related to historic
logging activity. Both were evaluated and determined not eligible for listing on the National Register in
1994. In addition, The Salt Lake Bay Hunting Blind and the Tenakee Inlet Log Cabin (SIT-441) were both
determined not eligible for listing on the National Register in 1994. A determination of eligibility for the
National Register for the cabin platform has not yet been performed (Cultural Resource Consultants
[CRC] 2012).
Wetlands and Waters of the U.S.
Section 404 of the Clean Water Act (CWA) gives the U.S. Army Corps of Engineers (USACE) authority to
regulate the discharge of dredged or fill material into waters of the U.S. Section 10 of the Rivers and
Harbors Act gives the USACE authority to regulate all work in, over, or under navigable waters of the
U.S., or work which affects the course, location, condition, or capacity of such waters.
According to the U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI) database,
wetlands and waters of the U.S. have been mapped in and adjacent to the project area (USFWS 2012a).
NWI mapping is generally derived from aerial photograph and topographic interpretation, and is not
“\HATTENBURG DILLEY & LINNELL 6 FDL Engineering Consultants

Preliminary Environmental Overview July 3, 2013
‘ground-truthed.’ A wetlands delineation and functional assessment will be required to map wetlands
within the project area and assess their ecosystem functions and values. This information will be used
during the permit application process to develop appropriate levels of compensatory mitigation for any
impacts to wetlands. Before proposing compensatory mitigation, however, the project design must
incorporate all appropriate and practical steps to avoid and minimize impacts to aquatic ecosystems.
Threatened and Endangered Species
The Endangered Species Act of 1973 was designated to protect critically compromised species from
extinction; this includes fish, wildlife, and plants that are listed by the federal government as
Endangered or Threatened. A species is listed either as a threatened, endangered, or candidate
depending on its status and degree of threat it faces. A "threatened species" is likely to become
endangered in the foreseeable future throughout all or a significant portion of its range. An
"endangered species" is in danger of extinction throughout all, or a significant portion of its range. A
"candidate species" are those for which USFWS has sufficient information on biological vulnerability and
threat(s) to support a proposal to the Threatened and Endangered Species List, but working on a
proposed rule is precluded by higher priority listing actions.
The USFWS and the National Marine Fisheries Service (NMFS) are the primary federal agencies
monitoring and documenting Threatened and Endangered species. The Endangered Species Act requires
federal agencies to consult with USFWS and/or NMFS to ensure proposed actions are not likely to
adversely impact listed threatened, endangered, or candidate species or result in the destruction or
adverse modification of designated critical habitat.
The following threatened, endangered, and candidate species are located in the Gulf of Alaska, including
the Inside Passage and southeast Alaska, and will require consultation with the appropriate regulatory
agency (Table 1) (USFWS 2012b):

Fish and Wildlife
The Anadromous Fish Act (Alaska Statute [AS] 16.05.871- .901) gives the Alaska Department of Fish and
Game (ADF&G) authority to regulate all activities within or across waterbodies bearing anadromous fish
species. The act requires individuals and government agencies proposing to alter or affect “the natural
flow or bed” of a specified waterbody or fish stream to obtain permit approval from ADF&G. Regulated
activities include construction; road crossings; gravel removal; mining; water withdrawals; the use of
vehicles or equipment in a waterway; stream realignment or diversion; bank stabilization; blasting; and
the placement, excavation, deposition, or removal of any material. According to ADF&G’s Catalog of
Waters Important for the Spawning, Rearing, or Migration of Anadromous Fishes, there is one
anadromous water body located within the project area: unnamed stream (referred to by project team
as Tenakee Creek) draining into Tenakee Inlet (AWC: 112-48-10350) (ADF&G 2012a). Chum, Coho, and
Pink Salmon, and Dolly Varden are present in the cataloged anadromous fish stream.
In addition to the Anadromous Fish Act, The Fishway Act (or Fish Passage Act AS 16.05.841) gives ADF&G
authority to regulate all activities within or across a stream bearing fish if it is determined that such uses
or activities could represent an impediment to the efficient passage of resident or anadromous fish.
Access roads and power transmission lines would intersect several fish bearing streams.
Bald and Golden Eagles
Bald eagles are protected under the Bald and Golden Eagle Protection Act of 1940, as amended (16
U.S.C. 668-668d), which prohibits anyone, without a permit issued by the Secretary of the Interior,
USFWS, from “taking” bald eagles, including their parts, nests, or eggs (USFWS 2012c). The Act defines
“taking” as "pursue, shoot, shoot at, poison, wound, kill, capture, trap, collect, molest or disturb.” For
“)HATTENBURG DILLEY & LINNELL 8 FDL Engineering Consultants
Tenakee Inlet Geothermal Reconnaissance
Preliminary Environmental Overview July 3, 2013
purposes of these guidelines, "disturb" means "to agitate or bother a bald or golden eagle to a degree
that causes, or is likely to cause, based on the best scientific information available, (1) injury to an eagle,
(2) a decrease in it s productivity, by substantially interfering with normal breeding, feeding, or
sheltering behavior, or (3) nest abandonment, by substantially interfering with normal breeding,
feeding, or sheltering behavior.” The USFWS published the National Bald Eagle Management Guidelines
(USFWS 2007) detailing circumstances under which the act may apply and advising how to minimize
impact to birds. According to the ADF&G species profile, Chichagof Island is outside the range of bald
eagles (ADF&G 2012c). However, the southeast Alaska region in general has the highest population
density of bald eagle in the U.S. and a bald eagle survey of the project area and transmission corridor
may be required.
Land Ownership, Land Use, and Land Management
The primary Land owner in the project area is the United States Forest Service (USFS). According to the
2008 Tongass National Forest Land and Resource Management Plan (USFS 2008), the geothermal
resource is located in a land management unit designated “Semi-Remote Recreation.” The objective of
this designation is to provide for recreation and tourism in natural-appearing settings where
opportunities for solitude and self-reliance are high. In addition, this area is in an inventoried Roadless
Area, where road construction or reconstruction is not allowed without approval from the USFS Chief.
Exploratory drilling and power plant construction and operation are subject to this rule.
RS2477 rights-of-way are contained in the Mining Law of 1866, and grant public rights-of-way across
unreserved federal land for transportation purposes. ADNR has identified over 600 routes in Alaska that
qualify as possible RS2477 rights-of-way. Preliminary research results did not reveal any RS2477 rights-
of-way in the vicinity of the project. However, consultation with ADNR will be required during
development of a NEPA document.
Power Transmission Corridor
The January 2008 Tongass National Forest Management Plan Land Use Designations Map (USFS 2008)
outlines a potential power transmission line route linking 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 (ADOT&PF 2004). 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. Although a power transmission line
connecting the power production facility to the existing electrical grid in Hoonah is an inherent
“)HATTENBURG DILLEY & LINNELL 9 DL Engineering Consultants
Tenakee Inlet Geothermal Reconnaissance
Preliminary Environmental Overview July 3, 2013
component of the proposed project, existing conditions along a chosen route have not been described
to the same level of detail as for the geothermal resource site and its immediate access roads.
Other Land Management
Northeast Chichagof Island is designated a Controlled Use Area by ADF&G (ADF&G 2012b). The area is
closed to the use of any motorized land vehicle for brown bear hunting, except as provided under terms
of a registration hunt permit. The area consists of a portion of Chichagof Island north of Tenakee Inlet
and east of the drainage divide from the northwest point of Gull Cove to the Port Frederick Portage,
including all drainages into Port Frederick and Mud Bay. Portions of the project area, including access
roads, barge landings, or power line interties are likely to be located within this area, but are not likely
to be affected by this designation.
IPEC and HDL will consult with stakeholders in the area to ensure that the project is consistent with
existing land management plans. The following sources of information were reviewed to determine
compatibility; none of these sources revealed any land use conflicts.

Air Quality
According to Alaska Administrative Code (AAC) 18 AAC 50, the community of Hoonah, Chichagof Island,
and the region surrounding the project area are considered Class I! air quality areas (Alaska Department
of Environmental Conservation [ADEC] 2012a). As such, there are designated maximum allowable
increases for particulate matter 10 (PM-10) micrometers or less in size, nitrogen dioxide, and sulfur
dioxide. Activities in these areas must operate in such a way that they do not exceed listed air quality
controls for these compounds.

Hazardous Materials and Contaminated Sites
The ADEC Contaminated Sites Database was reviewed to identify contaminated sites within the project
area and transmission corridor (ADEC 2012b). The mapping database contains location information,
types of hazardous material, agency staff investigations, and cleanup status. There are no contaminated
sites reported near the geothermal resource; however, there are several active sites along transmission
corridor near the community of Hoonah.
National Environmental Policy Act Process Overview and Regulatory Framework
NEPA requires federal agencies to integrate environmental values into their decision making processes
by considering the environmental impacts of their proposed actions and reasonable alternatives to
those actions. The process (Figure 5) also requires that environmental information is available to public
officials and citizens before decisions are made and actions to develop a project are taken. 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 address 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.
