This report represents our fourth and final deliverable under Contract # AEA-07-008. Our contract with AEA calls for this report to have been submitted by April 30", 2007. As agreed with AEA, submission of the report was deferred to allow the AEA to assemble internal and stakeholder comments on our Draft Final Report dated April 5, 2007. In preparing this Final Report, we have incorporated our responses to the AEA’s comments of August 14" in our Draft Final Report. We would like to make specific note of the fact that in accordance with our scope of work we have not updated the Draft Final Report to reflect information on any new developments in the electricity sectors of SE Alaska , British Columbia or the Lower 48 States during the period April 6", 2007 to the present. The purpose of this report is to provide a detailed description of the analysis we carried out in the study. In accordance with our contract, this study focuses on the hydro projects that could be developed and the proposed electrical transmission system that would interconnect presently isolated load centers within Southeast Alaska and interconnect Southeast Alaska with Northwest British Columbia. These projects would provide the opportunity to reduce present and projected diesel generation, to coordinate the operations of the region’s hydro plants to make the most efficient use of the water resources, to increase system reliability and to receive revenue from the export of power, thus creating important enabling conditions for new economic development within the study area. In preparing this report we have described the information we have obtained and have outlined the results of the analyses that we have carried out in our work under the Contract based on this available information. We have indicated the areas where additional information or more refined analysis will be desirable during Phase Il of the study or as part of other subsequent work on the projects that have been considered as part of this study. We note that while the word “feasibility” is included in the name of the project, the cost estimates provided in this report are based on existing studies, documents and other available information which generally are not based on feasibility level investigations. If you have questions on any of the information or results included in this report, please give us a call and we will be pleased to assist. Yours very truly, Robert Griesbach, P.

MEMORANDUM 0: Dave Carlson Southeast Conference Intertie Coordinator FROM: Dean Thompson DATE: March 16, 2004 SUBJECT: Legal Entity Options for Southeast Alaska Intertie Project L Introduction. In response to the Southeast Conference’s January 23, 2004, RFP and the subsequent teleconferences with you and the legal entity formation subcommittee, below is my analysis of the viable legal entity options available for ownership and/or operation of segments of the Southeast Alaska Intertie Project. There are several legal entity options available under Alaska law. However, based on the entity requirements and characteristics that were identified in the RFP, during our teleconference, and in the prior comments and discussions regarding intertie ownership, I believe that there are four primary, potentially viable options that should be discussed and considered in detail: (1) an electric transmission cooperative, (2) a limited liability company (“LLC”), (3) a nonprofit corporation, and (4) a for profit corporation. As will be explained below, each have advantages and disadvantages, but it appears that a transmission cooperative best satisfies the requirements for the project. As requested in the RFP, I have also prepared a matrix, which is attached to this memorandum. That matrix summarizes various aspects of each of the four potentially viable entities and relates them to entity requirements and characteristics that are of greatest concern with respect to the intertie project. IL. Other Entity Options Not Addressed in Detail. As an initial matter, I would like to briefly address some of the other legal entities that have been discussed in previous comments. A. Joint Action Agency. As you recall, two years ago there was significant discussion of forming a joint action agency (“JAA”) pursuant to AS 42.45.300. As you indicated in the RFP, this met with considerable opposition for various reasons. Among the most significant was that in order for the JAA to be tax exempt under federal income tax law, investor owned utilities (““IOUs”) could fs\SEC\SE Xtie\3-16-04 TO: Dave Carlson FROM: Dean Thompson DATE: March 16, 2004 SUBJECT: — Legal Entity Options for Southeast Alaska Intertie Project PAGE: QD; not be members. In addition, AS 42.45.300 would have to be amended to ensure the requisite sovereign powers to obtain a federal income tax exemption. Finally, in contrast to AS 42.45.310 (the statute for special JAAs like the Four Dam Pool JAA), AS 42.45.300 is very brief and lacks any detailed provisions regarding the governance and operation, let alone limited liability, for such a JAA. For reasons such as these, this is not a viable option for this project. B. Nonprofit Cooperative. In previous comments, a nonprofit cooperative under AS 10.15 was raised as a potential legal entity for the project. However, AS 10.15.005 expressly prohibits such a cooperative to be organized under those statutes for furnishing electric utility services. CG Limited Partnerships and Limited Liability Partnerships. Previous comments have raised the potential for use of a limited partnership or a limited liability partnership. Limited partnerships are often used in real estate developments and similar businesses. These entities have one or more general partners, who are primarily responsible for active management of the partnership, and one or more limited partners who are more “passively” involved and who have limited liability. However, for the intertie project, all interested parties will want to be more active in the legal entity and will want to maximize their limited liability and exemption from taxation. For these reasons, limited partnerships are not analyzed in further detail in this memorandum. Under Alaska law, a limited liability partnership provides more flexibility and greater overall limited liability for all partners. However, that same flexibility and liability protection exists with a LLC, and a LLC has the additional option of electing to be treated as a partnership or a corporation for purposes of federal income taxation without being subject to state law partnership rules. The LLC was discussed in detail in previous comments by one of the utilities that will participate in the intertie project, and it is addressed in detail below as well. Accordingly, limited liability partnerships are not analyzed further in this memorandum. D. Public Corporation. The RFP listed public corporations as a potential legal entity. Primary public corporations in Alaska include incorporated local governments and regional electrical authorities. However, public entities such as these do not allow for inclusion of other entities such as cooperatives and IOUs. fs\SEC\SE Xtie\3-16-04 iLO: Dave Carlson FROM: Dean Thompson DATE: March 16, 2004 SUBJECT: Legal Entity Options for Southeast Alaska Intertie Project PAGE: 5 E. Pooling Arrangements. Finally, the RFP contemplated consideration of a pooling arrangement to facilitate the intertie project. Any such arrangement, without new statutory provisions, would be based solely on contractual relations between the users of the intertie segments. This would not satisfy the limited liability, tax exemption, and organizational requirements identified for development of the intertie project in Southeast Alaska. Ill. Electric Transmission Cooperative. Based on the requirements listed in the RFP and our recent teleconference, it appears that the primary considerations for the choice of legal entity involve (1) inclusiveness of all utilities and power purchasers who are located near the future intertie segments; (2) protection of members from liability and undue risk; (3) exemption from income taxation; and (4) productive interface with the Southeast Conference regarding prioritization of future intertie segments. Of course, there are other considerations, but those four appear to be the most salient issues. Accordingly, much of this analysis will be concerned with those issues, particularly income tax issues. Regarding membership, nothing in AS 10.25 restricts utilities or power purchasers from being members of a cooperative for the purchase of transmission service. For decades electric cooperatives have had municipalities, private persons, and other utilities as members. Further, Alaska Statutes 10.25.010 and 10.25.020 provide electric and telephone cooperative utilities with broad powers to perform different types of activities. In several provisions, these statutes expressly allow a cooperative to construct, operate, and maintain “electric lines” and “transmission lines” and to “transmit electric energy.” AS 10.25.010(a)(4) and (a)(7); AS 10.25.020(1). AS 10.25.020(1) states, in relevant part: An electric cooperative may . . . generate, manufacture, purchase, acquire, accumulate, and transmit electric energy, and distribute, sell, supply, and dispose of electric energy to its members, to governmental agencies and political subdivisions, and to other persons not exceeding 10 percent of the number of its members .... (Emphasis added). fs\SEC\SE Xtie\3- 16-04 TO: Dave Carlson FROM: Dean Thompson DATE: March 16, 2004 SUBJECT: — Legal Entity Options for Southeast Alaska Intertie Project PAGE: 4 Specifically, generation and transmission cooperatives have operated for decades, and there are at least two transmission-only cooperatives currently operating in Georgia and the Southwestern United States. Accordingly, a transmission cooperative is well suited to serve the generation utilities and power purchasers in Southeast Alaska. You asked that I address when a utility or purchaser might become a member of the cooperative with respect to an intertie segment that will be constructed several years in the future. Alaska Statute 10.25 does not compel an absolute answer to that question. Instead, AS 10.25.080 simply requires that a person may not become a member unless he agrees to “use the services furnished by the cooperative when they are made available through its facilities.” However, it might be prudent to establish some standard in the articles or bylaws regarding how imminent the planning of a segment should be prior to having a future customer formally join as a member. Perhaps this standard could also incorporate when a specific segment recommendation or plan is recommended by the Southeast Conference. That would serve the dual purpose of facilitating interface between the planning and prioritization function of the Southeast Conference with the ownership and operation function of the transmission entity. Moreover, such a standard could also be included in the articles or bylaws of one of the other types of potential legal entities in the event a transmission cooperative entity is not pursued. With respect to limited liability, AS 10.25.410 expressly provides that a member of a cooperative is not liable or responsible for any debts of the corporation. Similarly, AS 10.25.141 provides that directors, officers, employees, and agents of a cooperative are not individually liable for conduct preformed within the scope of the person’s duties for the cooperative. Exemption from federal income taxation is an important benefit of a cooperative utility. Internal Revenue Code (“IRC”) Section S501(a) and (c)(12) exempt a mutual or cooperative electric company from federal income taxation if it derives at least 85 percent of its income from its members. The basic requirements for satisfying “cooperative principles” are (1) democratic control—one member-one vote; (2) operating at cost; and (3) subordination of capital. E.g., Puget Sound Plywood v. Commissioner, 44 T.C. 305, 307-08 (1965). Operating at cost means that the cooperative will not collect income from members greater or less than what is required to meet current losses and expenses. Of course, that does not mean that a cooperative cannot recover reasonable margins. In Revenue Ruling 72-36, the IRS held that operating at cost allows the cooperative to retain margins to fs\SEC\SE Xtie\3-16-04 702 Dave Carlson FROM: Dean Thompson DATE: March 16, 2004 SUBJECT: Legal Entity Options for Southeast Alaska Intertie Project PAGE: 5 expand the services of the cooperative and to maintain reserves for necessary purposes. The limit is that those funds cannot be accumulated beyond the “reasonable needs of the organization’s business.” /d. The IRS’ recognition of the need for a cooperative to earn and retain reasonable reserves for current and future operations fits well with the overall plan for the long-term development of the intertie project. Subordination of capital refers to the fact that cooperatives operate for the benefit of their member customers, not for equity investors. This means that over time, excess margins are returned to members and former members based on their patronage in the cooperative. Id. One issue that was raised in the RFP was whether different intertie segments could be operated on a stand-alone basis with respect to wheeling rates, O&M, and reserves. Neither AS 10.25 nor IRS rules prevent this. In fact, the general cooperative principle of serving members at cost implies that a cooperative should seek to charge different classes of members different rates based on differences in costs and allocations. See Unpublished TAM, Oct. 24, 1996. This supports the ability of a transmission cooperative to operate different segments based on the costs and circumstances of the service. One of the distinct benefits of a transmission cooperative over other potential legal entities is that the IRS has routinely granted tax exempt status to electric cooperatives under IRC 501(c)(12). In addition, the IRS has routinely granted those exemptions to G&T electric cooperatives, not just distribution cooperatives. In previous discussions, there was a question raised regarding whether a transmission-only cooperative would qualify for tax exemption under IRC 501(c)(12). There is nothing in the IRC or the IRS regulations that preclude that exemption, and the IRS granted Southwestern Transmission Electric Cooperative, Inc. a 501(c)(12) exemption as recently as January 4, 1999. Accordingly, it can be expected that a transmission cooperative formed to own and/or operate the Southeast Alaska Intertie Project would not draw undue scrutiny from the IRS. A related issue is whether plans to operate fiber optic facilities along the intertie segments would threaten the cooperative’s tax exempt status. This should not be a concern. So long as the cooperative satisfies the 85 percent member revenue test from wheeling income, this would not be a problem. In fact, another Alaska cooperative, Chugach Electric Association, Inc., owns and operates fiber optic facilities along its transmission facilities, and it has never presented an issue for its tax exempt status or authority under AS 10.25. Apart from federal income taxation, it has been asserted that a transmission cooperative would be required to pay the 0.25 mil per kWh cooperative gross revenue tax under fs\SEC\SE Xtie\3-16-04 TO: Dave Carlson FROM: Dean Thompson DATE: March 16, 2004 SUBJECT: Legal Entity Options for Southeast Alaska Intertie Project PAGE: 6 AS 10.25.540 and .555. However, despite the relatively small amount of that tax, it is doubtful that a transmission cooperative would be required to pay that tax since it applies only to kWh of “electricity sold at retail.” Providing transmission services for other utilities to sell either wholesale or retail power would not appear to be selling electricity at retail. Similarly, AS 10.25.580 provides that the inventory and fixtures of a business operated by a cooperative that is incidental to the furnishing of central station electric service, including “appliance stores or departments,” are not exempt from ad valorem taxes. However, it would appear that providing transmission service to a generating member is not “incidental” in the way that operating an appliance store would be. Accordingly, it appears doubtful that a transmission cooperative would be liable for these taxes. The primary disadvantages of a transmission cooperative legal entity are its 10 percent non-member service limit and the administrative burden of keeping records of member patronage and capital credits. The 10 percent non-member service limit is a state law requirement (AS 10.25.020(1)), not an IRS rule. It does impose a limitation on the ability of the cooperative to provide service to a large number of non-members. However, given that the participants appear to have decided that the entity should be as inclusive as possible with respect to the users of the interties that are allowed to become member, this likely will not be a significant impediment. The other primary disadvantage of a cooperative is that operating on cooperative principles requires careful record-keeping of past and current patronage capital. However, to the extent that any of the other potential entities seek to obtain their IRS tax exemption through IRC 501(c)(12), they would have the same type of record-keeping requirements. IV. Limited Liability Company. One of the participants advocated a LLC (AS 10.55) as a legal entity that might be preferable to a cooperative. As was noted by that participant, LLCs are very flexible entities, similar to a partnership, but with the benefit of having limited liability like a corporation or cooperative. Like a transmission cooperative, a LLC has no restrictions precluding it from having the participating utilities or power purchasers as members. Similarly, a LLC provides limited liability to its members in the same way that a corporation does. One potential drawback in that regard, however, is that LLCs are relatively new entities, and there is not a well-established body of law regarding the standards for piercing a LLC’s “corporate veil.” fs\SEC\SE Xtie\3-16-04 TO: Dave Carlson FROM: Dean Thompson DATE: March 16, 2004 SUBJECT: Legal Entity Options for Southeast Alaska Intertie Project PAGE: a) Also like an AS 10.25 cooperative, a LLC could arrange its articles and operating agreement to allow future users to become members as the planning for their segment becomes imminent. This could also incorporate a cooperative interface with the Southeast Conference, as was discussed above. The main disadvantage of a LLC, however, is the difficulty it will likely face in obtaining exemption from federal income taxation. It is true that there is nothing inherent about a LLC that precludes it from becoming exempt. However, I believe it would be much more difficult for a LLC to obtain such an exemption than it would be for an AS 10.25 cooperative. Under the Internal Revenue Code, there are not a lot of options for a transmission utility owned by IOUs and cooperatives to become exempt from federal income taxation. The only conceivable possibilities are IRC 501(c)(3) (charitable organizations), IRC 501(c)(4) (social welfare organizations, and IRC 501(c)(12) (electric cooperatives). I do not believe that the first two are applicable, as the purpose of the entity would not be what the IRS has traditionally granted exemptions for under IRC 501(c)(3) and (4). In his previous comments, the participant referenced above appeared to agree, but claimed that it may be possible for a LLC to qualify for an exemption under IRC 501(c)(12) by setting up its articles and operating agreement to satisfy the IRS’ cooperative principles requirements. There has been a recent trend at the IRS to allow LLCs certain beneficial tax treatments. For example, the IRS has held that a LLC that is wholly owned by a single, 501(c)(3) tax-exempt organization may be disregarded as an entity separate from its owner when numerous conditions are met. Ann. 99102, 1999-43 ILR.B. 545. Similarly, in a non-precedential private letter ruling, the IRS allowed a LLC to elect to be taxed as a taxable cooperative under Subchapter T where a taxable agricultural cooperative merged into the wholly-owned LLC in order to raise needed equity capital. PLR 200119016. However, to the best of my knowledge, the IRS has declined to extend this trend to granting a LLC tax exempt status under any other 501(c) exemptions. It may be that such an exemption will be possible in the future under the right circumstances, such as when the member of the LLC is otherwise exempt, but to the best of my knowledge, the IRS has not yet moved further in that direction. In any event, I believe the IRS would be much more willing to grant a 501(c)(12) exemption to an AS 10.25 cooperative than a multi-member LLC for purposes of operating a transmission utility. Moreover, even if a LLC fs\SEC\SE Xtie\3-16-04 TO? Dave Carlson FROM: Dean Thompson DATE: March 16, 2004 SUBJECT: — Legal Entity Options for Southeast Alaska Intertie Project PAGE: 8 obtained an exemption from income taxes, that does not necessarily mean that it would be exempt from state and local taxes. Another disadvantage of a LLC compared to a cooperative is that, although a LLC may technically be able to qualify for some types of grant funding, it is probably less politically attractive for a funding entity to issue such funds to a LLC. The perception, which is correct, is that most LLC’s are for-profit, taxable entities. In addition, although LLCs have significant flexibility, that flexibility exists at the cost of certainty and experience regarding what is required, allowed, and discretionary under AS 10.50. That adds a level of complexity in drafting, revising, and abiding by governing documents. For all of these reasons, I believe a cooperative is better suited than a LLC for ownership and operation of the Southeast Alaska Intertie Project. NV. Nonprofit Corporation. Another potential entity is a nonprofit corporation under AS 10.20. Like a cooperative and a LLC, a nonprofit corporation is able to have all of the potential participants as members, provides limited liability, can accommodate participants joining as members prior when planning for a segment is imminent, and can also provide for interface with the Southeast Conference. However, a nonprofit corporation would not be able to obtain a federal tax exemption, as it usually does, under IRC 501(c)(3) or (4). In addition, although it is possible that a nonprofit corporation might have a better chance than a LLC of persuading the IRS to grant it an exemption under 501(c)(12), the IRS would be less likely to grant it to a nonprofit corporation than to a cooperative. Beyond, the federal income tax issue, a nonprofit corporation would not enjoy the broad exemption from property taxes that a cooperative enjoys. The primary basis for a nonprofit corporation’s exemption from those taxes is Article IX, § 6, of the Alaska Constitution, which provides an exemption for property used exclusively for “non-profit religious, charitable, cemetery, or educational purposes.” Ownership and operation of a transmission project would not qualify for that exemption. By contrast, the ad valorem tax exemption for cooperatives in AS 10.25.540 is not dependent on such purposes. Although a nonprofit corporation has some potential advantages over a LLC, I believe a cooperative is preferable for ownership and operation of the intertie. fs\SEC\SE Xtie\3- 16-04 TO: Dave Carlson FROM: Dean Thompson DATE: March 16, 2004 SUBJECT: — Legal Entity Options for Southeast Alaska Intertie Project PAGE: 9 VI. ‘For Profit Corporation. There has not been significant discussion of using a for profit corporation for ownership of the intertie project. As was stated in the RFP, there is an obvious tax disadvantage associated with this option. In addition, AS 10.06.420 vests voting rights not on a one member-one vote basis, but based on the number of shares of stock that is owned. This is a significant departure from the democratic principles of a cooperative. In addition, AS 10.06.338 requires payment of consideration (contributions) for shares. Accordingly, under this statutory scheme, it would be difficult to retain equal voting rights within the entity. VII. Tax Ownership. One of the IOU participants expressed concern that a member performing contractual construction or operation and maintenance work for the cooperative might be deemed by the IRS to be a “tax owner” of the intertie facilities. I have discussed the issue with the IOU and have reviewed what I believe is the general basis for that concern. IRC 263-A and implementing Treasury Regulations at 1.263-A. However, I have not seen the precise tax accountant opinion that determined the “tax ownership” relating to the hydroelectric project. This is a complex, very fact-intensive area of federal income taxation, and more information would be needed regarding that prior situation to provide an exhaustive opinion on this issue as it relates to the intertie project. Nevertheless, it appears that there are substantial differences between the intertie project and the hydroelectric project that significantly reduce the likelihood that tax ownership would be imputed to a member of the intertie entity. First, a contract with the IOU or another member would, in form and substance, be nothing more than a services-type contract, presumably on a cost-plus or not-to-exceed amount basis. Second, there would be no implied or actual agreement that would give the contractor any expectation, however contingent, of obtaining direct ownership of the intertie. Third, the intertie entity, not the contractor, would have legal title to the facility as well as bear all risks of loss or damage to the property. Fourth, when the IOU purchases transmission service from the owning entity, it would be under traditional, per-unit-type wheeling rates. Under these circumstances, it appears that the instant situation is significantly different from the arrangements the IOU had regarding the hydroelectric facility. fs\SEC\SE Xtie\3- 16-04 TO: Dave Carlson FROM: Dean Thompson DATE: March 16, 2004 SUBJECT: Legal Entity Options for Southeast Alaska Intertie Project PAGE: 10 Therefore, balancing the benefits and burdens aspects discussed in Treasury Regulation 1.263A-2, as well as in various court decisions implementing that type of test, appears to reduce the risk of tax ownership with respect to this project. However, it would be prudent to carefully review this issue when forming the contractual arrangement between the intertie entity and a member contractor. In addition, all parties should ensure that the contract is negotiated at arms-length, at reasonably justifiable pricing, with the member abstaining from any entity vote on the contract. Finally, it would be advisable to obtain a more fact-specific tax analysis prior to finalizing that contract. It is also important to note that whatever risks may exist regarding this tax ownership issue, they do not appear to be significantly affected by the type of legal entity that is chosen to own the intertie. Instead, the material facts seem to be the relationship of the contracting member with the services to be performed and the terms and conditions under which that member obtains transmission services from the entity in the future. VIII. Conclusion. None of the potential legal entities discussed above are without advantages and disadvantages. However, based on the requirements and characteristics that most of the potential participants believe are important for the long term success of the Southeast Alaska Intertie Project, it appears that a nonprofit, electric transmission cooperative formed under AS 10.25 best satisfies those requirements. Specifically, a transmission cooperative has the greatest chance of obtaining an expeditious grant of a federal income taxation exemption under IRC S501(c)(12). The IRS is accustomed to granting such exemptions to electric cooperatives that are organized and operated under state electric cooperative statutes. In addition, a cooperative provides the same level of limited liability protection to its members as any of the other potential entities. Finally, the statutory scheme of AS 10.25 fits well with the general consensus that the intertie entity should be operated on an at-cost basis, under democratic, one member-one vote governance procedures, for the mutual benefit of all users of the intertie facilities. ‘tmg fs\SEC\SE Xtie\3- 16-04 PRIMARY ENTITY OPTIONS FOR CONSIDERATION For-Profit AS 10.06, et seq.

Existing Whitman Dam. _ This 40-foot high concrete gravity- arch dam was constructed in 1927 at the outlet to Whitman Lake, and provides 2,500 acre™ feet of regulated storage capability. The volume of storage is equivalent to 17 days of average inflow to the lake with no releases from the dam. New 45-inch diameter penstock. The new steel penstock will be 2,220 feet in length and will generally follow the same alignment of the two existing water supply pipelines from the dam to the existing vacuum valve house. The penstock will need to be buried up to a maximum depth of about 20 feet near the valve house to ensure that the penstock has sufficient pressure head to convey the full design flow to the turbines. The natural drainage area into Whitman Lake is 4.1 square miles. A portion of the flow from two creeks that do not naturally flow into the lake will be diverted to the lake via small diameter pipelines in order to increase the amount of flow available for power generation. The two diversions combined will effectively augment the natural basin flow by 30 percent. A 2,800 square foot composite concrete and steel-framed powerhouse will be located immediately uphill from the existing PRV building. The powerhouse will contain a 3.9 MW unit and a 0.7 MW unit for a total installed capacity of 4.6 MW. The larger unit will operate within a flow range between 50 and 150 cfs, and the small unit will operate between 12 and 30 cfs. Both turbines will be horizontal Francis type machines, which are the most appropriate type unit with the given head and flow conditions. In order to suppress the magnitude of hydraulic transient pressures in the penstock when flow is abruptly changed, an 18-inch diameter synchronous bypass valve will be installed to automatically open if the turbine wicket gates suddenly close due to a line fault or other reasons. Tailwater level exiting the powerhouse will be maintained at about EI. 40 for the small unit, and at EI. 20 for the larger unit. Discharge from the small unit will be conveyed to the hatchery. The plant switchyard will be located adjacent to the powerhouse and will contain a power transformer, circuit breakers and disconnect switches. About 1,200 feet of existing distribution line will need to be reconductored.

ALTERNATIVE DEVELOPMENT CONCEPTS A comparison is made of several possible developments utilizing the lakes in the three drainages (Cascade Creek, Delta Creek and Scenery Creek) separately and together. The heights above sea level of the several lakes within the area are shown on Exhibit IV-7, with portions of the stream profiles. The range of project configurations studied is comprehensive, and includes those proposed in previous reports by the USGS, USBR,R.W. Beck and the FERC. The alternatives considered can be grouped into four categories: 1. Projects utilizing Swan Lake only. 2. Projects utilizing Swan and Falls Lakes. 3 Projects involving Ruth Lake in combination with Falls Lake and/or Swan Lake. 4. Projects utilizing Scenery Lak~, with and without Swan Lake. The configurations studied are described briefly below, and in the accompanying exhibits. A summary of the features of each alternative is presented in Exhibit IV-18. Alternative 1-A (Swan Lake, without dam): A lake tap intake would be constructed 150 feet below the existing water surface of Swan Lake, allowing 66,000 acre-feet of active storage to be used for regulation. A tunnel and penstock would convey flow to a power plant at tidewater. Tunnel alignments either north or south of Cascade Creek could be considered, as shown. Construction of this alternative could be accomplished without requiring vehicle access beyond the power plant area (see Exhibit IV-8). Alternative 1-B (Swan Lake, with dam): A 125-foot high dam would raise the maximum water surface of Swan Lake, providing active storage between the elevations 1,540 and 1,620 (see Exhibit IV-8). This would allow construction of the power tunnel to take place "in the dry", and simplify the arrangements necessary to maintain instream flow in Cascade Creek, downstream of the lake. On the other hand, energy production would be only eight percent greater than Alternative 1-A. This would be insufficient to justify the additional costs associated with dam construction, including the provision of an access road to the dam site and tunnel inlet (see Exhibit IV-9). Alternative 2-A (Falls Lake): A 30-foot high dam would be built at the outlet of Falls Lake, to seal the pervious lake outlet (described in Section IV-5 —_—— III.D.1), and to raise the maximum water surface to elevation 1,180. A 'tunnel and penstock would lead from Falls Lake to a power plant at tidewater. Flow regulation would be provided by Swan Lake, from which a lake tap would feed a tunnel discharging through a control valve into Cascade Creek upstream of Falls Lake (see Exhibit IV-10). Total energy produced would be 12 percent less than from Alternative 1-A, due to the reduced hydraulic head on the generating plant. Alternative 2-B (Swan Lake/Falls Lake): This alternative' would be similar to Alternative 2-A, except for the addition of a power plant, located at the head of Falls Lake, fed by a pressure tunnel from the tapped intake at Swan Lake (see Exhibit IV- 10). Although there is additional construction cost for the additional conveyance, power plant, and transmission facilities, the benefits obtainable from the additional energy production, amounting to 22 percent of the output of Alternative 2-A, make this a more economical project. Alternative 2-C (Swan Lake/Falls Lake/Forebay): This also is similar to Alternative 2-A, but develops the drop from Falls Lake (elevation 1,180) to tidewater in two stages. The intermediate reservoir would be at elevation 580, in a natural depression (see Exhibit IV-11). This alternative was presented, in R.W. Beck's 1975 report, as the preferred approach for providing staged development to meet expected load growth of the municipal utilities in the project service area. It is neither appropriate nor economical as a means of serving a major regional load. Alternative 3-A (Swan Lake/Ruth Lake, with no dam): Without a dam to raise the water surface, Ruth Lake has insufficient volume to provide regulation of its outflow. In this alternative, which resembles Alternative 1-A, with the "alternate tunnel alignment", and the addition of a branch tunnel from a lake tap at Ruth Lake, additional storage is provided in Swan Lake in order to firm up the yield frbm Ruth (see Exhibit IV-12). The mode of operation would be to draw from Ruth when the water surface reaches 1,350, until the level is drawn down to 1,340. Then the flow would be cut off, to allow the lake contents to be replenished, and the project would continue to operate using flow from Swan Lake. Control valves in each tunnel branch would be provided to permit this type of operation. Alternative 3-B (Swan Lake/Ruth Lake, with dam): If Swan and Ruth Lakes were to be connected and operated within the same range of water surface elevations, it would be unnecessary to manage flows from each reservoir independently. Construction of a 180- foot high dam at Ruth Lake would allow this to be done, and would increase the energy output as a result of IV-6 the higher water surface in Ruth Lake (see Exhibit IV-12). However, th~ total energy production would be only 3.2 percent greater than that from Alternative 3-A, an amount insufficient to justify the additional cost of the dam at Ruth Lake. In addition, the access road required to reach the Ruth Lake dam site (see Exhibit IV-13) would be significant both in economic and en- vironmental terms. Alternative 3-C (Swan, Ruth and Falls Lakes): This alternative consists of the facilities of Alternative 2-B, with the addition of a valve-controlled feeder tunnel from Ruth Lake (see Exhibit IV-14). No energy would be generated from the Ruth Lake flow into Falls Lake, but the generation from the tidewater power plant would be augmented by the Ruth Lake contribution, which by the utilization of additional storage in Swan Lake, would constitute firm energy. The energy production would be increased 58 percent, as compared with Alternative 2- A, and would exceed that from Alternative 3-A by two percent. Alternative 4-A (Scenery Lake, without dam): Flows in Scenery Creek have not been gaged, but the size and elevation of the catchment area indicate that the amount and seasonal pattern of flows are similar to Swan Lake and .Cascade Creek (Johnson, 1962). As discussed in Section IV.B, drawdown without a dam should be limited, in order to ensure acceptable conditions for a lake tap. With a drawdown to elevation 865, usable storage of 44,000 acre-feet can be developed, sufficient to ensure a firm yield of 150 cfs (see Exhibit IV-3). A lake tap project, with a power plant at tidewater, is shown on Exhibit IV15. Energy output would be less than that from Swan Lake, due to the lower elevation of Scenery Lake. Firm energy would be 47 percent, and total energy 63 percent of that from Alternative 1-A. Alternative 4-B (Scenery Lake, with dam): This alternative would allow construction of a tunnel above the existing water level of Scenery Lake, and the provision of 66,000 acre- feet of storage by means of a dam. The dam would impound water up to a maximum surface elevation of 1,069, and would require in addition the construction of a saddle dam, approximately 60 feet high, to the north of the main dam site (see Exhibit IV-15). The access necessary to reach the dam site is shown on Exhibit IV-16. Provision of the dam would increase both the firm yield and the generating head. As compared with Alternative 4-A, the increase would be an additional 50 percent of firm energy, and 11 percent of total energy. Alternative 4-C (Swan and Scenery Lakes): In this alternative, 110,000 acre-feet of live storage is provided in Swan Lake, to firm up a yield of 350 cfs from the two drainages (before allowance for instream flow needs in both IV=7 ‘ creeks). ,Scenery Lake is operated at a constant water surface elevation as a forebay to a power plant at tidewater. Flow from Swan Lake entering Scenery Lake passes through a second power plant to yield additional, non-firm energy (see Exhibit IV-17). Although a dam would not be constructed, vehicle access for construction and operation would be required to the Scenery Lake power plant site. The alternative produces firm energy output 16 percent greater than Alternative 1-A, and total energy 57 percent greater. Other Combinations: Development at Scenery Lake could be combined with one of the alternatives involving Swan, Ruth and/or Falls Lake. If constructed concurrently, there would be some economies of scale in mobilizing for construction. Additionally, the projects would share joint transmission facilities over the route from Thomas Bay to Petersburg. Of the Scenery Lake alternatives, 4-A is somewhat more economical, and the costs and energy production of this alternative are combined with those of Alternatives 1-A, 2 B, 3-A and 3-C. The resulting figures for these four combinations are tabulated on Exhibit IV-1B. IV-B RECOMMENDED PROJECT ARRANGEMENT Four alternative project arrangements were analyzed with the principal difference bi3ing the method in which water is conveyed from Whitman Lake to a new powerhouse located at Herring Cove. The conveyance alternatives were: 1) A lake tap and tunnel arrangement, 2) A surface penstock following generally the same alignment as the existing water supply pip,elines from Whitman Dam to the hatchery. . 3) Utilizing the existing hatchery pipelines together with a new surface penstock paralleling the pipelines. 4) Aleast cost arrangement, with no integration of the hydro facilities with the existing hatchery. The first two project alternatives listed abpve were initially studied and described in the January 1998 draft report. The third and fourth alternatives were evaluated, at the request of KPU, after submitting the draft report. Based on detailed analysis of the four project arrangements, the third alternative listed above is recommended for development, . and is hereinafter referred to as the "Preferred Alternative". The project will consist of the following major elements: 1; Existing Whitman Dam. This 40-foot high concrete gravity dam was constructed in 1927 at the outlet to Whitman Lake, and provides 2,500 acrefeet of regulated storage capability. The volume of storage is equivalent to 17 days of average inflow to the lake with no releases from the dam. Some work will be needed to rehabilitate the existing dam to ensure its long- term stability and reliability. The recent dam safety inspection report identified, among other things, a concern with leakage though concrete joints, and measures to monitor or correct the problem. 2. New 45-inch diameter penstock. The new steel penstock will be 2,220 feet in length and will generally follow the same alignment of the two existing water supply pipelines from the dam to the existing vacuum valve house. The penstock will need to be buried up to a maximum depth of about 20 feet near .. the valve house to ensure that the penstock has sufficient pressure head to convey the full design flow to the turbines. 3. Two n~w diversion structures. The natural drainage area into Whitman Lake is 4.1 square miles. A portion of the flow from two creeks that do not naturally flow into the lake will be diverted to the lake via small diameter pipelines in order to increase the amount of flow available for power generation. The two diver~ions combined will effectively augment the nafural basin flow by 30 percent. 4.' Powerhouse. A 2,800 square foot composite concrete and steel-framed powerhouse will be located immediately uphill fr<?mthe existing PRY building. The powerhouse will contain a 3.9 MW unit and a 0.7 MW unit for a total installed capacity of 4.6 MW. The larger unit will operate within a flow range between 50 and 150 cfs, and the small unit will operate between 12 and 30 cfs. Both turbines will be horizontal Francis type machines, which are the most appropriate type unit with the given head and flow conditions. In order to suppress the magnitude of hydraulic transient pressures in the penstock when flow is abruptly changed, an 18-inch diameter synchronous bypass valve will be installed to automatically open if the turbine wicket gates suddenly close due to a line fault or other reasons. Tailwater level exiting the powerhouse will be controlled at about El. 40 for the small unit, and at El. 20 for the larger unit. Discharge from the small unit will be conveyed to the hatchery. 5. Switchyard and Transmission Line. The plant switchyard will be located adjacent to the powerhouse and will contain a power transformer, circuit breakers and disconnect switches. About 1,200 feet of existing distribution line will need to be reconductored. AVERAGE ANNUAL ENERGY The project will annually generate an average of 19,641,000 kWh. Average annual energy was determined based on synthesizing monthly streamflow records from actual USGS monthly and daily records on Beaver Falls Creek and Mahoney Creek because there do not exist any long-term actual streamflow records above the mouth of Whitman Creek. The Beaver Falls and Mahoney Creek basins are located immediately north of the Whitman Lake basin and are similar to the Whitman basin in size, terrain, average elevation and orientation to prevailing winds. The close similarities and proximity of these three basins provided an excellent basis from which to develop synthetic streamflow data for the Whitman Lake basin. Based on an installed plant capacity of 4.6 MW, the project will operate at a 49 percent plant factor. DEVELOPMENT SCHEDULE Project development will occur in three major phases; licensing, final design/contract documents, and construction. The project will need to be licensed with FERC prior to beginning construction. KPU currently holds a Preliminary Permit, issued by the Federal Energy Regulatory Commission, to study the project. It is currently anticipated that an application for license could be submitted to FERC by May 2000, assuming no major issues arise durjng the licensing process requiring lengthy study. Assuming a normal licensing proces?, without any major surprises, the project could be place into service by December 2003. LAKE CONNELL HYDROELECTRIC PROJECT EXISTING FACILITIES Lake Connell is presently being used as a SOUIce of processing water for a pulp mill located about 5 miles north of the Oiy of KetcJ:ti.kqn. Because the pulp mill will be permanently closed, Lake Connell and its associated conveyance facilities could be retrofitted for hydroelectric generation. , Lake Connell has a normal maximum pool level at E1254, which provides 9.5 feet above the dam crest elevation 250. Minimum pool level is El208 and average pool is at El 254. The spillway crest is fitted with 4-foot-high Obermeyer gates. The reservoir reportedly has a storage capacity of 3.75 billion gallons (11,400 acre- feet). The total drainage area behind the dam is 12.4 square miles. From the dam, water is routed to a filter plant at the pulp mill via a 3.1 mile pipeline comprising of: . 2.4 miles of 60-inch wood stave pipe; . 0.3 miles of concrete lined tunnel; - 0.3 miles of 48-inch wood stave pipe; and . 0.1 mile of 48-inch steel pipe. The wood stave pipe is not cfuectly connected with Lake Connell. To minimize the pressure to the wood stave pipel water is released from the reservoir via two 3D-inch outlets into a fore bay with normal pool El. 206. To help limit transient pressuresl a surge chamber was constructed at the downstream end of the pipeline. The forebay channel is 18 feet wide by 40 feet long along its initial reach and 9 feet wide by 24 feet long in its second reach before the entrance with the 5-foot- diameter pipeline. Motor operated contlol valves control the discharge into the forebay pool. Slide gates at the upstream end of the 30-inch outlets provide for emergency closure or for maintenance of the operating valves. The valves are located in a building with floor El. 211. The surge chamber is a 16-foot diameter vertical shaft excavated above the last of four tunnels along the waterway conduit It's location is at station 142+70. The tunnel section is an 8-Eoot high by 7-foot-wide. horseshoe shaped section with invert El181.66 feet below the surge chamberi the surge chamber rises to a top elevation of 224 feet. .PROPOSED PROJECT The proposed hydroelectric project at Lake Connell will have an installed capacity of about 1,700 kW. The primary components of the project are as follows: . By refurbishing the wood stave pipe by adding additional steel bands, the pipeline can increase its hydraulic pressure by an additional 50 feet This additional pressure will result primarily from hydraulically connecting the piping to the Lake Connell, but also from raising the normal operating pool from E1254 to E1258; . Extend the height of the existing surge tank by about 50 feet; . Extend a new steel or ductile iron pressure pipeline from the existing the pipeline toward a new powerhouse alongside Ward Cove; . Construct a new powerhouse, which will house a single horizontal Francis turbine~generator unit with approximately 1,700 kW of generating capacity at a plant factor of about 73 percent; and . Cormect from the adjacent switchyard, which would house a 6.9~115 kV power transformer, to the existing 115 kV Swan Lake transmission line. The project would raise the nowal maximum pool elevation of Lake Connell by 4 feet by replacing the 4-foot-high Obermeyer gates with 8-foot high gates. Even though the two 3D-inch Lake Connell outlet pipes are small and would result in flow velocity of up to 13 £ps, the head losses would only be a couple of feet. Therefore, it is assumed that they would remain intact. A steel manifold would connect the two 3D-inch outlets to a 60-inch-diameter section that would extend to and connect with the existing 60-inch wood stave pipe. The wood stave pipers m excellent condition considering its age of over 40 years.5 The 2.5-inch nominal thickness of the wood stave should suffice when increasing the pressure of the pipeline with additional steel bands. At this time, it is assumed that no other improvements need to be made on the wood stave pipelinei however, upon further inspection by a wood stave pipe design engineer, additional improvements may be shown to be required. The existing surge tank will need to be raised by about 50 feet to accommodate the increased pressure head of 50 feet. Presently, a re:inforced concrete cylinder with a diameter of 16 feet is assumed, although alternative choices of materials, such as wood, may later be shown to be more appropriate for the site. The powerhouse will be located near the high tide level at Ward Cove. Presently, it is assumed that the tailrace discharge will be at E118.0 feet. The 48-inch pipeline connecting the existing pipeline at the water filtration plant with the new powerhouse would extend a distance of about 2;300 feet. The pipeline would likely be an above ground structure and is assumed to be supported by concrete piers every 40 feet and would have concrete anchor blocks about every 300 feet. It is .assumed that the powerhouse would be located adjacent to the Tongass Highway bridge that crosses Ward Creek. During construction of the dam, the power conduit, located near the stream channel along with a small cofferdam upstream, would be used to divert streamflows. It will extend from an intake structure at the toe of the upstream face of the dam to a surface powerhouse at tidewater south of the mouth of Mill'Creek on Eastern Passage. The conduit will consist of a 9-foot diameter steel penstock approximately 2,450 feet long connecting to an aboveground surge tank at El 100. From the surge tank the penstock will extend another 400 feet and will branch to each unit before entering the powerhouse. The surface powerhouse will contain three vertical shaft Francis turbines with a nominal total installed capacity of 12,000 kW corresponding to a discharge of 1,070 cfs under an average gross head of 163 feet. Approximately 46 miles of 69-kV single circuit transmission line will extend from the switchyard at the powerhouse to connect to existing distribution systems in Petersburg and Wrangell (see Fig. 1). The transmission line requires approximately 1.0 miles overland near the plant, 1.5 miles of underwater cable across Eastern Passage from the powerhouse, connecting to 7.0 miles of overhead transmission along the western side of Wrangell Island to the tip of the island. From there approximately 11.4 miles of underwater cable crossing is required between Wrangell Island and Mitkoff Island, connecting to approximately 25 miles of overhead transmission line constructed along Mitkoff Highway to the City of Petersburg. About 3.5 miles of construction access roads would be required to construct a portion of the overhead transmission line on Wrangell Island. Permanent access to the project site would be provided by port facilities constructed near the outlet of Mill Creek adjacent to the powerhouse on Eastern Passage, with approximately 0.8 miles of 'permanent access road from the port and powerhouse to the dam. 2. ANITA-KUNK LAKES PROJECT The Anita Lake and Kunk Lake drainage basins are located approximately 14 miles southwest of Wrangell on the northern tip of Etolin Island (Fig. 1 shows the general location). Two adjacent drainage basins are diverted and utilized with the proposed project arrangement to increase the usable runoff for power generation at this site, making a totai drainage area of 8 square miles. Development of a project at this site involves construction of two dams, two power conduits and powerhouses, plus diversion dams and ditches for interbasin transfers of water. The project arrangement is shown in, Fig. 6. A 60-foot high concrete-faced rockfill dam with crest at El 1430 is required at the outlet of Anita Lake in order to raise the normal water surface to El 1420, to regulate the 2;5 square mile drainage basin above the lake. An open channel spillway would be provided in the left ab~tment. The power conduit, a 3D-inch diameter surface steel penstock, would extend approximately 6,300-feet from the dam, along the left side of Anita Creek to a surface powerhouse on the southern shore of Kunk Lake. The powerhouse would contain a single generating unit with a nominal installed capacity of 4,300 kW, operating under a net head of 1~007 feet. Kunk Lake would be raised to a normal water surface of El 350 by a concrete-faced rockfill dam at its outlet. An open channel spillway would be excavated in rock on the left abutment. The power conduit would extend from an intake structure, approximately 2,750 feet to a surface powerhouse located at tidewater on Zimovia Strait. The conduit would consist of a 7-foot diameter concrete-lined tunnel approximately 1,600 feet long to a portal about 800 feet upstream of the powerhouse, and a 4-foot diameter steel penstock to the powerhouse. The powerhouse contains a single generating unit with a nominal installed capacity of 4,300 kW, op- erating ~nder a net head of 310 feet. In addition to the above project features, a small di- version dam is required about 1,200 feet upstream of the bend on Anita Creek and a 1,700-foot long ditch to divert streamflows into Kunk Lake. Another diversion ditch, approximately 2,500 feet long is required to divert streamflows from the basin to ~he north of Kunk Lake, to a point upstream of the dam at the lake outlet. It is estimated that this latter diversion will provide an additional 15 cfs of average annual inflow to the Kunk Lake Reservoir. An estimated 3.5 square miles of drainage area above the dam site drains directly into Kunk Lake, an additional 0.4 square miles from the diversion of Anita Creek flows, and 1.6 square miles by diversion of the basin to the north of Kunk Lake for a total of approximately 8 square miles of drainage area. Approximately 1.6 miles of 69-kV transmission line would connect the two powerhouses on this Project, and from the lower powerhouse an additional 52.8 miles would be required to connect with existing distribution systems at Petersburg and Wrangell. This transmission line includes approximately 1.1 miles of underwater cable from the lower powerhouse across Zimovia Strait, 3.6 miles (including access road) north along the eastern side 6f the Strait, to a point about 10.5 miles south of Wrangell, where it would follow the alignment of the existing road into Wrangell. The portion from Wrangell to Petersburg involves 37.6 miles total (same as for the Virginia Lake Project) including approximately 1.2 miles of overhead transmission from Wrangell to the tip of Wrangell Island, 11.4 miles of submarine cable and 25 miles of overhead transmission to Petersburg. Access to the project site would be provided by a per manent port facility constructed near the lower powerhouse on Zimovia Strait. Approximately 0.6 mile of access road would be constructed from the port to the dam on Kunk Lake, plus 2.5 miles of additional access road to the Anita Lake dam and powerhouse site. 3. THOMS LAKE PROJECT Thorns Lake is located on Wrangell Island approximately 17 miles south of Wrangell, situated withiri a drainage basin which drains to the southeast into Zimovia Strait (Fig. 1 shows the gen a eral location). Approximately 8.1 square miles of area surrounding Thorns Lake drains directly into the lake and additional drainages of 6.4 and 4.5 square miles would be diverted from basins lying to the north and east respectively. The Thorns Lake project arrangement is shown in Fig. 7. Three small concrete-faced rockfill darns would be required to raise thewat~r level of Thorns Lake to El 300. The reservoir level would be controlled by an open-channel spillway constructed on the right abutment of the east darn, which would discharge into Thorns Creek to the southeast. Diversion darns on creeks to the north and east of Thorns Lake along with ditches approximately 3.3 and 2.0 miles long would divert runoff from the two basins, to Thorns Lake. A power conduit would extend approximately 4,800 feet from an intake located on the right abutment of the south darn to a surface powerhouse near tidewater on Zimovia Strait. It would consist of approximately 4,200 fe~t of 7-foot diameter tunnel to a portal about 600-feet upstream of the powerhouse, where it connects to a 5-foot diameter surface steel penstock. A surge tank located approximately 1,700-feet upstream of the powerhouse is required. The powerhouse would cbntain two generating units with a total nominal installed capacity of 7,500 kW~ operating under a net head of 274 feet. The project would require approximately 57.7 miles of 69-kV transmission line to connect with the distribution systems in Petersbyrg and Wrangell. This would involve construction of approximately 9.6 miles (including access road) from the powerhouse north along Zimovia Strait, to a point about 10.5 miles south of From the powerhouse approximately 3.6 miles of new overhead transmission line would extend to the eastern shore of Woronkofski Island> connecting to 2.1 miles of underwater cable across Zimovia Strait to Wrangell Island. An additional 3.0 miles of overhead transmission line would follow the alignment of the existing road north to Wrangell. The portion from Wrangell to Petersburg (same as for Virginia Lake Project) would involve approximately 11.4 miles of underwater cable and 26.2 miles of overhead transmission line. Site access would be provided by port facilities constructed on the western side of the Island near the mouth of Sunrise Creek> and approximately 1.2 miles of permanent access road would be required from the port to the ppwerhouse location. ~-™o=> UNITED STATES OF AMERICA 93 FERC ~ 62,055 FEDERAL ENERGY REGULATORY COMMISSION Haida Corporation Project No. 11480-001 ORDER ISSUING ORIGINAL LICENSE (Major Project) October 24, 2000 INTRODUCTION On November 25, 1997, Haida Corporation (Haida) filed, pursuant to Part | of the Federal Power Act (FPA), 1an application for a major license to construct, operate and maintain the 5.0-megawatt (MW) Reynolds Creek Hydroelectric Project No. 11480 (Reynolds Creek Project). The project would be located on Reynolds Creek, near the town of Hydaburg, on Prince of Wales Island, in southeast Alaska. Proposed project facilities include a 10.9-mile-long transmission line that would cross Hetta Inlet, a navigable waterway of the United States. The project would not occupy any federal lands. BACKGROUND The Commission issued notice of the application on February 11, 1998. Motions to intervene were filed by the National Marine Fisheries Service (NMFS) on April 1 0, 1998; American Rivers and Alaska Department of Fish and Game (ADF&G) on April 15, 1998; and the U.S. Department of the Interior (Interior) on April 17, 1998. All motions were unopposed and granted, including Interior's late motion. The Commission staff issued a draft environmental assessment (draft EA) for the project on September 9, 1999. Comments on the draft EA were filed by the Haida Corporation, Alaska Power & Telephone Company, NMFS, ADF&G, Alaska Division of Governmental Coordination (ADGC) and Natural Heritage Institute. Their concerns were considered in preparing the final environmental assessment (final EA) for this project, which was issued hays a full frre ere all comments received from interested agencies and individuals Ma erent Ry whether, and under what conditions, to issue this license. PROJECT DESCRIPTION. The proposed project will consist of a 20-foot-long, 6-foot-high diversion dam; a 3,200 foot-long penstock; a 150-acre lake with 600 acre-feet of new storage capacity; a powerhouse with one 1 ,500-kilowatt (kW) horizontal impulse turbine/generator during phase 1; a second PROB tuinstgpnegaior to be added during phase 2; and an overhead 34.S-kilovolt (kV), Project No. 11480-001 2 10.9-mile-long transmission line. The total capacity of the project will be 5.0 MW. A detailed project description is contained in ordering paragraph B(2). NEED FOR POWER By producing hydroelectricity, the Reynolds Creek Project displaces the need for diesel generation, thereby avoiding some power plant emissions and creating an environmental benefit. Consequently, the operation of the Reynolds Creek Project would likely reduce annual carbon emissions in the region. The amount of greenhouse gases emissions that are avoided depends on the type of power displaced, which is region-specific. In southeast Alaska, the region where the Reynolds Creek Project is located, the alternative fuel is almost entirely diesel. SAFETY OF THE PROJECT Our Portland Regional Office determined that the project would have a low hazard classification, in that failure of the diversion dam would not pose a risk to life or property. Because of the low hazard classification, the project would not be subject to Part 12, Subpart 0, of the Commission's regulations. WATER QUALITY CERTIFICATION Under Section 401 (a)(1) of the Clean Water Act, 2the Commission may not issue a license for a hydroelectric project unless the state certifying agency has either issued water quality certification for the project or has waived certification by failing to act on a request for certification within a reasonable period of time, not to exceed one year. 3 By agreement between the U.S. Army Corps of Engineers (Corps) and the Alaska Department of Environmental Conservation (ADEC), application for a Department of the Army permit to discharge dredged or fill material into navigable waters under Section 404 of the Clean Water Act also serves as application for state water quality certification. On November 21, 1997, the ADEC received from Haida a completed Section 404 permit application. Because the ADEC did not act on the request within 1 year from the date of receipt, the water quality. certification is deemed to be waived under section 4.38(f)(7)(ii) of the Commission's regulations. By letter dated July 30, 1999, the ADEC, under Section 401 of the Clean Water Act, issued a Certificate of Reasonable Assurance to construct and operate the Reynolds Creek Project. This certificate was superseded entirely by a revised Certificate of Reasonable Assurance issued by the ADEC on August 19, 1999. The ADEC included one condition for the 233 D.S.C. § 1341 (a)(1). 3 Section 401(a)(1) requires an applicant for a federal license or permit to conduct any activity which may result in any discharge into navigable waters to obtain from the state in which the discharge originates certification that any such discharge will comply with applicable water quality standards.

HATCH ACRES Conclusions — AK-BC Intertie ¢ The AK-BC Intertie would provide a further opportunity to secure the energy future for Southeast Alaska. e The technical feasibility and market potential of the proposed future hydro facilities et related transmission features look promising but cannot be definitively determined at this time. e The permitting of the proposed hydro facilities and transmission features face significant, but not necessarily insurmountable, environmental & institutional challenges.

HATCH AES Market Oversight e If the State can be assured that the projects are constructed so they will produce power for 50 years (the term of their FERC license), it may be possible to evaluate their economics over that longer timeframe, substantially increasing their marketability. e Long term project operation would probably require more direct involvement by the State.

HATCH ACRES Conclusions — AK-BC Intertie e The AK-BC Intertie would provide a further opportunity to secure the energy future for Southeast Alaska. e The technical feasibility and market potential of the proposed future hydro facilities & related transmission features cannot reliably be determined at this time. e The permitting of the proposed hydro facilities and transmission features face significant, while not necessarily insurmountable, environmental & institutional challenges.
