project on the Susitna River has been studied for more than 50 years and is again being considered by the State of Alaska as a long term source of energy. In the 1980s, the project was studied extensively by the Alaska Power Authority (APA) and a license application was submitted to the Federal Energy Regulatory Commission (FERC). Developing a workable financing plan proved difficult for a project of this scale. When this existing difficulty was combined with the relatively low cost of gas-fired electricity in the Railbelt and the declining price of oil throughout the 1980s, and its resulting impacts upon the State budget, the APA terminated the project in March 1986. In 2008, the Alaska State Legislature authorized the Alaska Energy Authority (AEA) to perform an update of the project. That authorization also included a Railbelt Integrated Resource Plan (RIRP) to evaluate the ability of this project and other sources of energy to meet the long term energy demand for the Railbelt region of Alaska. Renewable hydroelectric power is of particular interest to the railbelt because of its potential to provide stable power costs for the region. Of all the renewable resources in the railbelt region, the Susitna projects are the most advanced and best understood. HDR was contracted by AEA to update the cost estimate, energy estimates and the project development schedule for a Susitna River hydroelectric project. This report summarizes the results of that study. The initial alternatives reviewed were based upon the 1983 FERC license application and subsequent 1985 amendment which presented several project alternatives:  Watana. This alternative consists of the construction of a large storage reservoir on the Susitna River at the Watana site with an 885-foot-high rock fill dam and a six-unit powerhouse with a total installed capacity of 1,200 megawatts (MW).  Low Watana Expandable. This alternative consists of the Watana dam constructed to a lower height of 700 feet and a four-unit powerhouse with a total installed capacity of 600 MW. This alternative contains provisions that would allow for future raising of the dam and expansion of the powerhouse.  Devil Canyon. This alternative consists of the construction of a 646-foot-high concrete dam at the Devil Canyon site with a four-unit powerhouse with a total installed capacity of 680 MW.  Watana/Devil Canyon. This alternative consists of the full-height Watana development and the Devil Canyon development as presented in the 1983 FERC license application. The two dams and powerhouses would be constructed sequentially without delays. The combined Watana/Devil Canyon development would have a total installed capacity of 1,880 MW.  Staged Watana/Devil Canyon. This alternative consists of the Watana development constructed in stages and the Devil Canyon development as presented in the 1985 FERC amendment. In stage one the Watana dam would be constructed to the lower height and the Watana powerhouse would only have 4 out of the 6 turbine generators installed, but would be constructed to the full sized powerhouse. In stage two the Devil Canyon dam and powerhouse would be constructed. In stage three the Watana dam would be raised to HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 2 Final Draft its full height, the existing turbines upgraded for the higher head, and the remaining 2 units installed. At completion, the project would have a total installed capacity of 1,880 MW. As the RIRP process defined the future railbelt power requirement it became evident that lower cost hydroelectric project alternatives, that were a closer fit to the energy needs of the railbelt, should be sought. As such, the following single dam configurations were also evaluated:  Low Watana Non-Expandable. This alternative consists of the Watana dam constructed to a height of 700 feet, along with a powerhouse containing 4 turbines with a total installed capacity of 600 MW. This alternative has no provisions for future expansion.  Lower Low Watana. This alternative consists of the Watana dam constructed to a height of 650 feet along with a powerhouse containing 3 turbines with a total installed capacity of 390 MW. This alternative has no provisions for future expansion.  High Devil Canyon. This alternative consists of a roller-compacted concrete (RCC) dam constructed to a height of 810 feet, along with a powerhouse containing 4 turbines with a total installed capacity of 800 MW.  Watana RCC. This alternative consists of a RCC Watana dam constructed to a height of 885 feet, along with a powerhouse containing 6 turbines with a total installed capacity of 1,200 megawatts (MW). The results of this study are summarized in Table 1. Table 1 - Susitna Summary Alternative Dam Type Dam Height (feet) Ultimate Capacity (MW) Firm Capacity, 98% (MW) Construction Cost ($ Billion) Energy (GWh/yr) Schedule (years from start of licensing) Lower Low Watana Rockfill 650 390 170 $4.1 2,100 13-14 Low Watana Non- expandable Rockfill 700 600 245 $4.5 2,600 14-15 Low Watana Expandable Rockfill 700 600 245 $4.9 2,600 14-15 Watana Rockfill 885 1,200 380 $6.4 3,600 15-16 Watana RCC RCC 885 1,200 380 $6.6 3,600 15-16 Devil Canyon Concrete Arch 646 680 75 $3.6 2,700 14-15 High Devil Canyon RCC 810 800 345 $5.4 3,900 13-14 Watana/Devil Canyon Rockfill/Concrete Arch 885/646 1,880 710 $9.6 7,200 15-20 Staged Watana/Devil Canyon Rockfill/Concrete Arch 885/646 1,880 710 $10.0 7,200 15-24 HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 3 Final Draft In all cases, the ability to store water increases the firm capacity over the winter. Projects developed with dams in series allow the water to be used twice. However, because of their locations on the Susitna River, not all projects can be combined. The Devil Canyon site precludes development of the High Devil Canyon site but works well with Watana. The High Devil Canyon site precludes development of Watana but could potentially be paired with other sites located further upstream. Development of any of the alternatives for the Susitna River will require careful consideration of many factors. Environmental issues, climate change and sedimentation are discussed in this report and the risk associated with these issues is considered manageable. An updated evaluation of seismicity has been done by others and this risk is also considered manageable. Hydroelectric power has many economic and environmental benefits including long-term rate stabilization. Because the cost of the water (fuel) is essentially free and maintenance costs are minimal, the cost per kilowatt hour is driven largely by the project finance terms and is not subject to fluctuations in fuel cost. HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 4 Final Draft 2 Background The Susitna River has its headwaters in the mountains of the Alaska Range about 90 miles south of Fairbanks. It flows generally southwards for 317 miles before discharging into Cook Inlet just west of Anchorage. Contained entirely within the south central Railbelt region, the Susitna River is situated between the two largest Alaska population centers of Anchorage and Fairbanks. The Bureau of Reclamation first studied the Susitna River’s hydroelectric potential in the early 1950s, with a subsequent review by Corps of Engineers in the 1970s. In 1980, the Alaska Power Authority (APA; now the Alaska Energy Authority) commissioned a comprehensive analysis to determine whether hydroelectric development on the Susitna River was viable. Based on those studies, the APA submitted a license application to the Federal Energy Regulatory Commission (FERC) in 1983 for the Watana/Devil Canyon project on the Susitna River. The license application was amended in 1985 for the construction of the Staged Watana/Devil Canyon project at an estimated cost of $5.4 billion (1985 dollars). Developing a workable financing plan proved difficult for a project of this scale. When this existing difficulty was combined with the relatively low cost of gas-fired electricity in the Railbelt and the declining price of oil throughout the 1980s, and its resulting impacts upon the State budget, the APA terminated the project in March 1986. At that point, the State of Alaska had appropriated approximately $227 million to the project from FY79-FY86, of which the project had expended $145 million to fund extensive field work, biological studies, and activities to support the FERC license application. Though the APA concluded that project impacts were manageable, the license application was withdrawn and the project data and reports were archived to be available for reconsideration sometime in the future. In 2008, the Alaska State Legislature, in the FY 2009 capital budget, authorized the AEA to reevaluate the Susitna Hydro Project as it was conceived in 1985. The authorization also included funding a Railbelt Integrated Resource Plan (RIRP) to evaluate various sources of electrical power to satisfy the long term energy needs for the Railbelt portion of Alaska. A Susitna River hydroelectric project could play a significant role in meeting these needs. 2.1 Project Scope The scope of this study was to collect and review pertinent information from the original studies and license application from the 1980’s and re-estimate the project energy, costs and development schedule. The initial 1982 FERC license application and subsequent 1985 amendment analyzed several project alternatives:  Watana. This alternative consists of the construction of a large storage reservoir on the Susitna River at the Watana site with an 885-foot-high rock fill dam and a six-unit powerhouse with a total installed capacity of 1,200 megawatts (MW).  Low Watana Expandable. This alternative consists of the Watana dam constructed to a lower height of 700 feet and a four-unit powerhouse with a total installed capacity of 600 MW. This alternative contains provisions that would allow for future raising of the dam and expansion of the powerhouse.

This alternative consists of the construction of a 646-foot-high concrete dam at the Devil Canyon site with a four-unit powerhouse with a total installed capacity of 680 MW.  Watana/Devil Canyon. This alternative consists of the full-height Watana development and the Devil Canyon development as presented in the 1983 FERC license application. The two dams and powerhouses would be constructed sequentially without delays. The combined Watana/Devil Canyon development would have a total installed capacity of 1,880 MW.  Staged Watana/Devil Canyon. This alternative consists of the Watana development constructed in stages and the Devil Canyon development as presented in the 1985 FERC amendment. In stage one the Watana dam would be constructed to the lower height and the Watana powerhouse would only have 4 out of the 6 turbine generators installed, but would be constructed to the full sized powerhouse. In stage two the Devil Canyon dam and powerhouse would be constructed. In stage three the Watana dam would be raised to its full height, the existing turbines upgraded for the higher head, and the remaining 2 units installed. At completion, the project would have a total installed capacity of 1,880 MW. As the RIRP process defined the future railbelt power requirement it became evident that lower cost hydroelectric project alternatives, that were a closer fit to the energy needs of the railbelt, should be sought.

This alternative consists of the Watana dam constructed to a height of 700 feet, along with a powerhouse containing 4 turbines with a total installed capacity of 600 MW. This alternative has no provisions for future expansion.  Lower Low Watana.

This alternative has no provisions for future expansion.  High Devil Canyon. This alternative consists of a roller-compacted concrete (RCC) dam constructed to a height of 810 feet, along with a powerhouse containing 4 turbines with a total installed capacity of 800 MW.  Watana RCC. This alternative consists of a RCC Watana dam constructed to a height of 885 feet, along with a powerhouse containing 6 turbines with a total installed capacity of 1,200 megawatts (MW). Preliminary energy, cost, and schedule estimates for the analyzed alternatives are described in the following sections. 3 Preliminary Energy Estimate 3.1 Hydrologic Analysis At the time the original study was issued in 1983 the hydrologic record contained data from 1950 to 1981. To develop an updated energy estimate for the Susitna hydroelectric project alternatives, a synthesized hydroelectric record for each site was created by a drainage area proration of daily flow data from United States Geological Survey (USGS) gage 1529000 at HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 6 Final Draft Gold Creek. USGS gage 1529000 has a period of record from water year 1950-1996 and 2002- 2008. The hydrology of the upper Susitna Basin is dominated by melt water from snow and glaciers in the spring and summer, and substantial freezing during the winter months. As a result, a majority of the flow occurs between mid-April and mid-October. The following figure shows the average monthly flow at the Watana dam site for each year of record. Figure 1 - Susitna River at Watana Hydrologic Variation The manner in which precipitation and runoff might be affected by the impacts of either natural variability and/or potential climate change is discussed at the end of this report. 3.2 Evaluation of Firm Winter Capacities and Average Annual Energy The amount of energy that can be produced from hydroelectric projects is a function of the amount of available water and in the case of storage projects, how the available water can be regulated (systematically released). For the RIRP evaluation process, in addition to the average annual energy, the firm capacity attainable during winter months is of particular importance. For hydroelectric projects, the firm capacity is almost always lower than the installed generation capacity for a project. For the purposes of this study work, firm capacity is defined as: “The amount of power the project can generate on a continuous basis from Nov. 1 through April 30 with 100% reliability”. The firm capacity is always driven by low periods in the hydrologic cycle. Since the hydrologic cycle varies, it is also desired to know at what level of reliability the project can generate at levels higher than the firm capacity. It should be noted that this is only one manner of regulation. The water can be regulated in a variety of different means in order to achieve other objectives, such as peaking, spinning reserve or backup capacity. For this study, the average annual energy and winter plant capacities for the alternatives were estimated using a HDR proprietary energy modeling software tool customized for this particular HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 7 Final Draft purpose (Computer Hydro-Electric Operations and Planning Software or (CHEOPS)). Major assumptions used in the modeling efforts are presented below. 3.3 Model Assumptions and Data Sources  Inflow hydrology was based upon USGS gage #1529000 located at Gold Creek on the Susitna River and scaled by a drainage area correction factor representing each of the dam sites.  Reservoir capacity and area curves for the Watana and Devil Canyon alternatives were based on information presented in the 1985 FERC application. For the High Devil Canyon project this data was derived from USGS topographical data.  Tailwater curves for the Watana and Devil Canyon projects were obtained from the 1985 FERC application and estimated for High Devil Canyon.  Operating reservoir levels were obtained from the 1985 FERC application for the Watana, Low Watana and Devil Canyon projects, from the 1982 Acres feasibility study for the High Devil Canyon project, and estimated for the Lower Low Watana project.  Environmental flow release constraints were as presented in the 1985 FERC application and scaled according to drainage areas for the various sites.  Evaporation coefficients were obtained from the 1985 FERC application. Total reservoir evaporation was estimated in the 1985 FERC application to be between one (1) and three (3) inches per month in summer, with negligible evaporation during winter months.  Equipment performance was based on vendor data obtained in 2008 specifically for the Watana and Devil Canyon projects and was assumed to be representative for the other projects.  Headloss estimates were based on the water conveyance design from the 1985 FERC application for the Watana and Devil Canyon alternatives and the 1982 Acres feasibility study for the High Devil Canyon alternative.  The reservoir was assumed to start full at the beginning of the simulation and was allowed to fluctuate over the remaining period of the simulation.  Generation from Nov. 1 to April 30, “winter,” was at a constant capacity level (“block loaded”).  Generation from May 1 to Oct. 31, “summer,” was to maximize energy with the objective of the reservoir being full on Nov. 1.  Rule curves for summer target reservoir elevations were developed for each alternative using a mass balance approach. The ratio of the average monthly inflow volume to the average annual inflow volume during each of the reservoir filling months were used to set target elevations for the reservoir.  Energy losses of 1.5 percent for un-scheduled outages and 2 percent for transformer losses were applied to the total generation.  Active storage remained constant over the simulation period. Dead storage in the reservoirs was assumed to be sufficient to contain sedimentation loads. HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 8 Final Draft  No ramping rate restrictions were imposed on either reservoir drawdown or downstream flow. To determine the firm capacity for the combined Watana and Devil Canyon projects, the regulated flow from Watana was assumed to pass unregulated through Devil Canyon with the Devil Canyon pool at maximum operating level. Key input parameters related to energy generation are shown in Table 2 below.

For each day from November through April the flow through the powerhouse was limited to the amount necessary to satisfy a prescribed capacity demand given the available head, environmental flow constraints, and reservoir operational restrictions. During the months of May through September energy production each day was maximized if the reservoir elevation was above the target rule curve. If the reservoir elevation was below the target rule curve then generation was limited to the amount that would allow the downstream environmental flow constraints to be met. The simulation was repeated at various increasing winter load demands until the maximum firm capacity was determined. To better quantify the effect of storage and extreme low water years on the firm winter capacity, winter load levels in excess of the firm capacity were also evaluated. The results of this analysis HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 9 Final Draft are expressed as a capacity at a given percent exceedance level. For example, a project might have a firm capacity of 250 MW at a 100% exceedance level and a firm capacity of 300 MW at a 98% exceedance level. This would mean that the project could provide 250 MW 100% of the time in the winter over the simulation period or 300 MW 98% of the time over the winter. The large change in firm capacity between the 100% exceedance level and the 98% exceedance level for all alternatives is primarily due to a single low water year in 1970. The resulting firm capacities and average annual energy production estimates are presented in Figure 2 and partially summarized in Table 3. Detailed input assumptions and results of these energy analyses are provided in Appendix A of this report. The average annual energy production was relatively constant over the range of winter power demand levels that were modeled.

In 1985 the cost for developing the staged Watana/Devil Canyon project was $5.4 billion (1985 dollars). The Devil Canyon and High Devil Canyon alternatives were as envisioned in the 1980’s. The four rockfill Watana Dam configurations considered in this evaluation are depicted in Figure 3 below. Figure 3 - Watana Dam Configurations The estimates for the Watana, Low Watana-Expandable, Devil Canyon and Staged Watana- Devil Canyon alternatives were developed in depth in a March 2009 Interim report and were revised to reflect changes primarily in transmission, access and camp costs. Using this information as a base, new estimates were made for the development costs of the Low Watana Non-Expandable and of the Lower Low Watana alternatives. Cost estimates of $5.4 billion for the High Devil Canyon RCC and $6.6 billion for the Watana RCC alternatives were provided by a separate contractor using similar assumptions and are presented here for completeness of information. The following discussion details the basis for the cost estimates for the Watana embankment projects, the assumptions that were used in creating those estimates, and provides a summary of the projected construction costs. 4.2 Expandability The Low Watana alternative, as proposed in previous studies, included provisions for eventual expansion of the dam from 700 feet to a height of approximately 885 feet and an increase in powerhouse capacity from 800 MW to 1200 MW. The most notable of these provisions are the design of the dam cross section and construction of the powerhouse and water conduits to their ultimate capacity. The two non-expandable alternatives contain no provisions for future expansion. 885FULL WATANA LOWER LOW WATANA LOW WATANA - EXPANDABLE LOW WATANA - NON-EXPANDABLE 650 0 500 1000 700 (Ref.) HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 12 Final Draft For the Low Watana Expandable alternative the dam cross-section is expanded on the upstream side to provide the opportunity to later raise the dam. This results in additional fill material due to the wider base. The powerhouse, powerhouse equipment, and water conveyance scheme would be built to house six units, but only four turbines would be initially installed. For the Low Watana Non-expandable alternative the cross-section is narrower and does not accommodate expansion of the dam at a later time. Similarly the powerhouse and water conduit features are sized for only four turbine/generator units instead of six. 4.3 Quantities Quantities for the construction cost estimates were based upon detailed estimates developed as part of the 1982 Acres feasibility study for the full sized Watana project and the Devil Canyon project. To estimate the quantities of the smaller Watana alternatives, the full sized Watana quantities were scaled based on the size of the development. As part of a separate report, quantities were developed for the High Devil Canyon alternative based upon a new conceptual design using RCC construction. Table 4 summarizes the embankment fill volumes that were used for the cost estimates. The dam heights and fill volumes of the Watana and Low Watana Expandable configurations were adopted directly from the 1985 FERC application. The embankment volumes for the Lower Low Watana and Low Watana Non-Expandable alternatives were estimated assuming a 2:1 side slope on the downstream portion of the dam and a 2.4:1 side slope on the upstream portion of the dam as were assumed for the other alternatives. Volume changes were limited to the rock-fill and riprap portion of the dam only. The concrete volumes for the Devil Canyon, Watana RCC, and High Devil Canyon alternatives are shown for comparison. Table 4 - Estimated Total Fill Volumes Alternative Type Total Fill Volume(cy) Watana Rockfill 61,000,000 Low Watana Expandable Rockfill 32,000,000 Low Watana Non-Expandable Rockfill 22,000,000 Lower Low Watana Rockfill 17,000,000 Devil Canyon Concrete Arch 1,300,000 Watana* RCC 15,000,000 High Devil Canyon* RCC 11,600,000 * R&M, 2009. The quantity estimates for the water conduit layouts and powerhouses for all alternatives were based on the 1985 layout as opposed to the 1983 layout. The 1983 arrangement used a separate penstock for each unit with a very long conveyance scheme. The 1985 arrangement employed a headrace for every two units bifurcating into dedicated penstocks. The total length of HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 13 Final Draft conveyance was less than half that of the 1983 design. To maintain consistency with the energy model, and to further refine the cost estimates, the 1985 configuration was used for this study. Table 5 summarizes the design features that were assumed in each estimate. The powerhouse and water conveyance systems for Watana and the Low Watana Expandable alternatives were designed to service six units as contemplated in 1983. However, the water conduit layout reflects the 1985 arrangement with three headraces bifurcated into six penstocks and discharged into two tailraces. Low Watana Non-Expandable was assumed to be built to accommodate a four-unit powerhouse with two headraces, four penstocks and a single tailrace. Lower Low Watana was designed for a three-unit powerhouse with one headrace, three penstocks, and one tailrace. The diameters of the water conduits were sized to be consistent with the 1985 design. The powerhouse structures were also scaled accordingly.

This cost data was used to develop the estimates presented in the Interim Report and the same pricing was used in this study. Lump sum items were inflated using a construction cost index. For the water-to-wire turbine-generator equipment estimates, budget pricing for the Watana alternative was requested directly from manufacturers. The water-to-wire equipment includes turbines, generators, turbine shutoff valves, and other miscellaneous mechanical and electrical equipment, including installation costs. The equipment costs for other smaller alternatives were developed by scaling the Watana vendor quotes on a per kilowatt basis. HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 14 Final Draft 4.5 Indirect Costs A contingency of 20 percent was added to the direct construction costs to reflect level of design and uncertainty in the project. Project licensing, environmental studies and engineering design were estimated at 7 percent of direct construction costs. Construction management was estimated at 4 percent of the direct construction costs, and has been included as a separate line item. 4.6 Interest During Construction and Financing Costs Costs associated with interest during construction and project financing are not included in the estimates. 4.7 Changes from 1983 Design The camps, access roads and transmission, infrastructure assumptions used in the 1983 configuration have been modified as discussed below. 4.7.1 Camps Reductions were made in the scale of the permanent and construction camps needed to accommodate the workers. These changes were made based on the fact that permanent town facilities were no longer necessary due to advances in remote project operation. It was also assumed that due to modern construction methods, the number of construction personnel could be reduced. It was assumed that 750 people would need to be housed for the Lower Low Watana arrangement, 825 people for Low Watana and 900 people for Watana. In 1983 it was originally assumed that housing would be provided for 3000 people plus families. Budget pricing for the construction camp was provided by vendors. 4.7.2 Access For all the Watana alternatives, access is assumed to be via the Denali Highway from the north as shown in Figure 4. The route would include the upgrade of 21 miles of the Denali Highway to a construction grade road and the construction of approximately 40 miles of new road to the Watana site. The price per mile of new road has been assumed at $3M/mile which is the current budgetary estimate of the Alaska Department of Transportation and Public Facilities for the road to Bettles and Umiat from the Dalton Highway which is similar in nature to the road that would be required for a Susitna project. Upgrading of the Denali Highway has been assumed to be $1M/mile and local site roads have been estimated at $750k/mile. HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 15 Final Draft Figure 4 - Proposed Access Route For the Devil Canyon and High Devil Canyon alternatives, rail access was assumed and will originate on the Parks Hwy near MP 156 and proceed upstream on the south side of the river. 4.7.3 Transmission A separate study (EPS, 2009) has investigated the transmission lines and interconnection requirements for the entire Alaska railbelt region as part of the RIRP process and the results are incorporated here at the direction of the AEA. This study estimates that a transmission line from the project site to the substation at Gold Creek would cost approximately $4.5M/mile. Substation costs are estimated at $16M per location. No costs have been assumed to increase or modify the regional transmission grid beyond the Gold Creek substation. 4.8 Conclusions The approach, methodology and assumptions previously described resulted in the estimated project costs detailed below in the summary table.

These schedules extend from approval, through licensing, design, construction, and commissioning. The primary purpose of these schedules is to provide timelines for cash flow and estimated energy revenue to determine economic feasibility. These schedules assume that:  Construction times are based on 1983 FERC license application.  The licensing process from start to FERC order is estimated at 7 to 10 or more years. We have set a reasonable target of 8 years for the proposed project analysis, provided that the effort is begun immediately, ambitiously, fully funded, and conducted in parallel with environmental studies, engineering, and with active public outreach and cooperation by stakeholders.  The FERC License Application will be based on the 1985 application, updated to reflect more than 20 years of regulatory changes and changes in engineering and construction methods.  Any new environmental studies will be based on data acquired during the studies in the 1980’s, updated to reflect present site conditions, public interests, wildlife, and recreational needs.  Construction will begin immediately upon issuance of the license.  Roads and staging will be state permitted outside the FERC project and will begin several years before FERC license, including pioneer and permanent roads, airports, bridges, construction camps and staging areas. Building facilities in advance of the project license is the most effective way to trim the projected timeline although there is some uncertainty whether permits could be obtained to construct these facilities before the project license is issued. The schedule for each of the project alternatives would be extended by one to two years if this assumption is not valid.  Construction of diversion dams and tunnels will begin on issuance of the license, with upstream and downstream coffer dams and tunnels to divert the Susitna River during construction of main dams at Watana/Devil Canyon.  Spillway construction will follow diversion dam and tunnel construction, and will include site preparation, approach channels, control structures, gates, stoplogs, chute, and flip buckets for main and emergency spillways.  Dam construction at Watana will follow site preparation, grouting, and installation of a pressure relief system.  The main dam construction at Devil Canyon will include a thin-arch concrete dam, preceded by site preparation, foundations, abutments, and thrust blocks. Rock-fill saddle dam construction will follow grouting and pressure relief system.  The powerhouse and transmission will include power intake, tunnels/penstock, surge chamber, tailrace, powerhouse, turbine/generators, mechanical/electrical systems, switchyard, control buildings, and transmission lines. HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 18 Final Draft  Reservoir filling will be based on the latest hydrologic data for inflow and turbine data for outflow.  Devil Canyon construction will commence immediately upon completion of Watana for the Watana/Devil Canyon alternative.

The design lifetime for a modern dam is greater than 100 years. The following discussion is not intended to be all inclusive but rather highlight the likely major areas of concern. 6.1 Engineering The projects being contemplated for the Susitna River would be on the larger end of the scale in the world in terms of size of the dams. Projects of this size have not been undertaken in the United States for many decades. As such, a major engineering effort will be required. 6.2 Siltation Rivers, by nature, transport the products of erosion to the oceans. Dams interrupt this flow of material. Given time the effective amount of storage in the reservoir behind the dam can diminish. The alternatives investigated here have been designed with dead storage to accommodate bedload and it is not expected that siltation will have any detrimental affect on the energy projected energy production of any of the projects during their design lifetime. 6.3 Seismicity Seismic (earthquake) events have the potential to effect hydroelectric projects. The main areas of concern are damage from ground shaking, opening of faults along the dam axis, landslides and settlement, and the creation of large waves in the reservoir. The previous studies on seismicity have concluded that these concerns can be designed for and therefore do not pose a significant threat. New analytic methods are now available to evaluate more complex seismic situations and these evaluations, along with the most stringent safety factors would be incorporated into a modern project design (R&M, 2009). 6.4 Climate Change There has been much discussion about climate change and what the effects of climate change will be on river flows. Analyses of the potential affects of climate change on the Susitna River are included in Appendix D. The annual runoff from the Susitna River basin shows remarkable balance during very disparate climate regimes. The analyses support the consistent supply of water from the basin precipitation to support hydro-power generation regardless of the climate fluctuations. While global climate models suggests additional warming may impact the Arctic and Alaska, it seems very unlikely that these impacts will cause an unbalance in the runoff production of the basin. Based on this, there is no conclusive evidence to suggest that runoff will be statistically different in the next 50 years from what it has been in the last 50 years. 6.5 Environmental Issues After the Susitna project was discontinued in 1986 a database of 3,573 documents was created. In September 2008, the 87 most-relevant documents were scanned into HDR’s files, of which 18 HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 20 Final Draft of the most relevant environmental documents were summarized. A synthesis of the 7 most- pertinent documents was completed. Because not all of the documents were summarized, some relevant information has likely been overlooked; however, most information was included in the synthesis. These documents contain information on potential impacts of the proposed project and mitigation proposals for those impacts. Specifically, the documents deal with fisheries resources, botanical resources, wildlife resources, and cultural resources in the potential project area. The documents divide the Susitna River Basin into 4 geographic regions:  Impoundment zones  Middle Susitna River  Lower Susitna River  Access roads and transmission lines The potential impacts and mitigation options are discussed for each category in each geographic region as much as possible. It is important to note that not all categories will be impacted in all geographic regions. Mitigation for the proposed impacts is divided into the following categories: avoidance, minimization, rectification, reduction, and compensation. Avoidance is always the preferred mitigation, though it is not usually feasible. Compensation is the only mitigation option for many of the impacts. 6.5.1 Fisheries Impacts The fisheries resources have the highest potential to be impacted by the project. Most of the potential impacts will occur in the middle Susitna River. There will be impacts due to changes in water quality, thermal activity, the water’s suspended sediment load, reservoir draw-down fluctuations, impoundment zone inundation, flow regime, and lost fish habitat. Not all impacts to fish populations will be negative. For example, the increase in winter water temperatures could lead to the creation of more overwintering habitat and thus greater fish survival; however, the cooler spring water temperatures will slow fish growth. In the Watana impoundment zone, 51 river miles will be inundated and transformed into reservoir habitat. An additional 27 miles of tributary streams and 31 lakes will be inundated. In the Devil Canyon impoundment zone 31 miles of the main river channel will be inundated and an additional 6 miles of tributary streams will be impacted. Mitigation for these impacts was proposed by compensation through land acquisition, habitat modification, and reservoir stocking. 6.5.2 Botanical Impacts The project area contains 295 vascular plant species, 11 lichen genera, and 7 moss taxa. Low Watana inundation will permanently remove 16,000 acres of vegetation. Devil Canyon inundation will permanently remove 6,000 acres of vegetation. Watana inundation will permanently remove an additional 16,000 acres of vegetation. There will be a total of 38,000 acres of vegetation permanently removed. Most of the vegetation inundated will be spruce forest. An additional 836 acres of vegetation will be permanently removed due to access road HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 21 Final Draft construction. In the transmission corridor affect on vegetation will be minimal due to intermittent placement of control stations, relay buildings, and towers. There will be limited botanical impacts downstream from the reservoir(s). These involve changes to the vegetation due to a more stable environment. Due to flow regulation there will no longer be major flooding events, which destroy the riparian vegetation; instead; rather, there will be succession of the riparian vegetation and colonization of new floodplains. The increase in winter water temperatures will decrease the amount of ice scouring that occurs, which will result in effects similar to those caused by the decrease in flooding. Botanical resource mitigation will consist largely of compensation for permanently removed vegetation. 6.5.3 Wildlife Impacts Within the Susitna River Basin there are 135 bird species, 16 small-mammal species, and 18 large-mammal and furbearing species. There are currently no known listed endangered species in the project area. There will be 5 classes of potential impacts to terrestrial vertebrates: Permanent habitat loss, including flooding of habitat and covering with gravel pads or roads. Temporary habitat loss and habitat alteration resulting from reclaimed and revegetated areas such as borrow pits, temporary right of ways, transmission corridors, and from alteration of climate and hydrology. Barriers, impediments, and hazards to movement. Disturbances associated with project construction and operation. Consequences of increased human access not directly related to project activities. Mitigation for the proposed impacts involve mostly compensation since there will be permanent habitat loss for most species. 6.5.4 Cultural Resource Impacts Within the proposed project area, 297 historic and prehistoric archaeological sites were located. An additional 22 sites were already on file. Sites located within 500 feet of the reservoir’s maximum extent may be indirectly impacted due to slumping from shoreline erosion. Indirect impacts may also result from vandalism due to increase in access to the sites. The project has the potential to impact 140 sites. None of these sites will occur in the proposed road corridor or transmission lines. The majority of these sites are relatively small prehistoric sites. Mitigation for the lost cultural resources will mostly occur through data recovery. Preservation would also be used for some sites. Options to consider include construction of protective barriers to minimize erosion, controlled burial, or fencing of the site to restrict access. Currently, there are a variety of federal, state, and local land use plans that encompass the Susitna Basin. 6.5.5 Carbon Emissions According to the United Nations working group on carbon emissions from freshwater reservoirs the worst case carbon emissions from a reservoir in a boreal climate is 6.7 grams per square meter per year (United Nations, 2009). For the Watana/Devil Canyon alternative this equates to HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 22 Final Draft 465,000 metric tons of carbon per year or 0.065 metric tons per MWhr. The US Department of Energy reports the average carbon emissions due to electric generation for the State of Alaska to be 0.6261 metric tons per MWhr. Operation of the Susitna project has the potential to eliminate up to 4 million metric tons of carbon production per year. 1 http://www.eia.doe.gov/cneaf/electricity/st_profiles/alaska.html HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 23 Final Draft 7 References Acres 1981.

HYDROELECTRIC PROJECT11/18/09 Created NBA Checked PB HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report 11/23/2009 Final Draft Appendix D: Climate Change Analyses For the purposes of this submittal, the appendices have been attached as PDFs. HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report   Climate Change, Natural and Potentially Man-made, and the Susitna River Basin Concern over the impacts of climate change on Alaska have been voiced and evaluated since 2000 in a series of updated reports entitled: “Climate Change Impacts on the United States - The Potential Consequences of Climate Variability and Change Overview: Alaska”. These assessments have been updated in 2004 and 2007 by the National Assessment Synthesis Team, US Global Change Research Program. A summary of the concerns are listed below: Alaska has warmed substantially over the 20th century, particularly over the past few decades. Average warming since the 1950s has been 4F (2C). The largest warming, about 7F (4C), has occurred in the interior in winter. The growing season has lengthened by more than 14 days since the 1950s. Some records suggest that much of the recent warming occurred suddenly around 1977. Alaska has also grown wetter recently, with precipitation over most of the state increasing 30% between 1968 and 1990. The observed warming is part of a larger trend through most of the Arctic corroborated by many independent measurements of sea ice, glaciers, permafrost, vegetation, and snow cover. In contrast to other regions, the most severe environmental stresses in Alaska at present are climate-related. The figures below show the observed warming and the variation in precipitation that we reported in this series of reports. It is interesting to note that the temperature of Alaska has experienced warming trends from 1920-1940 and again from about 1975 to 2000. In between these two “warming periods”, cooler periods were noted from 1900-1920 and again from 1950-1974. Thus it is very important to note that cyclical changes in Alaskan temperature have been documented though the causes have not. The figure on the right shows that Alaskan precipitation experiences considerable year-to-year variability but has been relatively consistent on a decadal and cyclical basis. Figure 1: Observed temperature and predicpitaiton trends in Alaska from 1900-2000. Courtesy National Assessment Synthesis Team, US Global Change Research Program Global Circulation Models project that rapid Arctic warming will continue. For Alaska, the Hadley and Canadian models project 1.5-5F (1-3C) more warming by 2030, and 5-12F (3-6.5C) (Hadley) or 7-18F (4-10C) (Canadian) by 2100. The warming is projected to be strongest in the north and in winter. Both models also project continued precipitation increases in most of the state reaching 20-25% in the north and northwest, with areas of up to 10% decrease along the HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report   south coast. Projections indicate that increased evaporation from warming will more than offset increased precipitation, however, making soils drier throughout most of the state. As a means of comparison, the Alaskan warming observed from 1950 to 2000 was from 29F to 37F or about 8F. This warming is comparable to the anticipated warming predicted by the Global Climate Models by ~2050 so in effect, Alaskans may already have seen a glimpse of the future. . Climate change describes the variation in Earth's global and regional atmosphere over time. These changes are likely caused by a combination of natural processes and possible man-made activities. The rise in the Earth's average surface temperature is known as global warming. Some scientists attribute the accelerating rate of global warming to manmade greenhouse gas emissions while others suggest that natural variability of the climate plays an equal role to man-made activities. Global warming, regardless of its cause, is currently impacting Alaska and will continue to impact it in a number of ways. These impacts include melting polar ice, the retreat of glaciers, increasing storm intensity, wildfires, coastal flooding, droughts, crop failures, loss of habitat and threatened plant and animal species. Globally, 2005 was the warmest year on record (using records dating back to 1880) with a sustained period of warming in the Arctic during 2000-2005. Evidence includes NASA satellite data that shows Arctic perennial sea ice decreasing by 9% per decade since 1979. Less ice means more open water-which means greater absorption of solar energy-which leads to increased warming in the ocean, and in turn accelerates more ice loss. Three major climate regimes contribute to the Alaska’s climate variability: the Arctic Oscillation (AO), the Pacific Decadal Oscillation (PDO) and the ENSO or El Nino/La Nina. In looking at the impacts of climate on the Susitna River hydro-power generation potential, an appreciation of these naturally occurring climate regimes is important. A brief discussion of each regime and its relationship to both the mean annual discharge and total runoff follows. The Arctic Oscillation The Arctic Oscillation refers to opposing atmospheric pressure patterns in northern middle and high latitudes. The oscillation exhibits a "negative phase" with relatively high pressure over the polar region and low pressure at mid-latitudes (about 45 degrees North), and a "positive phase" in which the pattern is reversed. In the positive phase, higher pressure at mid-latitudes drives ocean storms farther north, and changes in the circulation pattern bring wetter weather to Alaska, Scotland and Scandinavia, as well as drier conditions to the western United States and the Mediterranean. In the positive phase, frigid winter air does not extend as far into the middle of North America as it would during the negative phase of the oscillation. Weather patterns in the negative phase are in general "opposite" to those of the positive phase, as illustrated below. HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report   Effects of the Positive Phase | Effects of the Negative Phase of the Arctic Oscillation of the Arctic Oscillation (Figures courtesy of J. Wallace, University of Washington) Over most of the past century, the Arctic Oscillation alternated between its positive and negative phases. Starting in the 1970s, however, the oscillation has tended to stay in the positive phase, causing lower than normal arctic air pressure and higher than normal temperatures in much of the United States, including Alaska, and northern Eurasia. Please note that this positive phase AO is not caused by global warming but a function of the natural variability and cycles in the atmosphere. http://nsidc.org/arcticmet/quickfacts/climate_change_lesson.htmlChanges beginning in the 1970s and 1980s due to the persistent positive phase AO include:  warmer winters and springs over North America, Alaska and Eurasia, partially compensated by cooling over the northern North Atlantic,  warmer air over the central Arctic Ocean,  warming in the Arctic Ocean at 200 to 900 meters depth,  reductions in sea ice and snow extent,  increases in terrestrial precipitation,  warming permafrost in Alaska and Russia, and cooling permafrost in Canada,  increased plant growth and northward migration of the tree line. Most of these trends derive from relatively short environmental records, and the magnitude of the high-latitude temperature increase is no larger than the inter-decadal temperature range for the last century. Since climate is naturally variable, the occurrence of an exceptionally warm period may not be abnormal because it may fall well within the expected range of temperature variability for a specific area. The Arctic Oscillation (AO), shown below, is an important Arctic climate index with positive and negative phases, which represents the state of atmospheric circulation over the Arctic. HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report   Figure 2: Arctic Oscillation Phases 1950-2004 ( National Center for Environmental Prediction). The positive phase (red) brings lower-than-normal pressure over the polar region, steering ocean storms northward, bringing wetter weather and the warmer conditions to Alaska as discussed earlier. While the value of the AO index was strongly positive in the early 1990's compared to the previous forty years, the value of the AO has been low and variable for the last nine years. The year to year persistence of positive or negative values and the rapid transition from one to the other is often referred to as "regime-like". A detailed comparison of the AO phase and the Susitna River’s total annual runoff is shown in the figure below. It indicates that no correlation in either the positive or negative phases of the AO could be found. This result was surprising since the AO is considered by many climatologists to have the most profound impact on precipitation in Alaska. The chart below is presented to substantiate this result. The yellow box indicates a +/-10 percent of the average total runoff for the river. As is easy to see, the total runoff appears to be relatively “climate regime” free from AO influences. This result bodes well for the consistent ability of the river to provide needed flow to sustain hydro-power generation. Cool Phase  Warm Phase  HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report   Figure 3 Comparison of the total annual runoff of the Susitna River and the Nov-Mar phase of the Pacific Decadal Oscillation Similar results were derived for both the ENSO (El Nino/La Nina) cycles and the Pacific Decadal Oscillation (PDO) shown in the two following figures. Again, these results were not expected as the PDO is known to have a marked impact on precipitation in mountain ranges along the Canadian and California coasts and in the Rocky Mountains from Montana to New Mexico. The PDO comparison shown in Figure 4 demonstrates a remarkably balanced distribution. The greatest runoff years are balanced between positive, neutral and negative phases. While it is not understood why this balanced distribution exists, it is significant because it supports consistent runoff for hydro-power generation and water supply. Note in Figure 5 that the PDO goes through warm and cold phases like the AO. ‐7 ‐6 ‐5 ‐4 ‐3 ‐2 ‐1 0 1 2 3 ‐2,000,000 4,000,000 6,000,000 8,000,000 10,000,000  AO AO HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report   Figure 4 Comparison of the total runoff (acre ft) of the Susitna River and the Pacific Decadal Oscillation Figure 6 Warm and cool phases of the Pacific Decadal Oscillation 1950-2006 ‐3.00 ‐2.50 ‐2.00 ‐1.50 ‐1.00 ‐0.50 0.00 0.50 1.00 1.50 2.00 ‐2,000,000 4,000,000 6,000,000 8,000,000 10,000,000  Series1 HDR Alaska Susitna Hydroelectric Project Conceptual Alternatives Design Report   While this evaluation sounds redundant, the figure below shows the Multivariate ENSO Index or MEI plotted against the total annual runoff. Values of the MEI above 0.5 represent the presence of a El Nino while values less than -0.5 represent a La Nina is present. Once again a balanced distribution is present. Figure 8 shows the MEI plotted from 1950 to 2009. It shows a cool phase from 1950-1975 and a warm phase from 1976-2006 and possibly the start of another cool phase in 2007.

The AO experienced a cool phase until about 1982 and then entered into a warm phase that continues into 2009. The lag between the AO and the PDO and MEI suggests either gradual influence exists or that a totally different phasing is being experienced. It is interesting to note that the AO, PDO and MEI were all in their warm phase from 1985 until 2005 when the greatest atmospheric and global warming were recorded. It is during this period that Alaska experienced its greatest surface warming which is consistent with the atmospheric warming noted during extended El Nino periods. Perhaps the syncronicity of these cliamte regimes contributed to the observed warmer Alaskan climate. The key point is that the total runoff of the Susitna River basin shows remarkable balance during very disparate climate regimes. The analyses support the consistent supply of water from the basin precipitation to support hydro-power generation regrardless of the climate fluctuations. While global climate models suggests additional warming may impact the Arctic and Alaska, it seems very unlikely that these impacts will cause an unbalance in the runoff production of the basin.
