The alternatives have been previously identified in the Draft Design Section Report and Draft System Studies Report, which were previously issued for review and-comment.. The-three primary. alternatives. are referred.to as-Tesoro Route, Enstar Route, and Quartz Creek Route. Based on the results of the preliminary design efforts and environmental evaluations, each corridor has a base route identified. These base routes are potential routes that have attributes that may allow the route to be ultimately permitted under an environmental assessment (EA) or environmental impact statement (EIS) process. The cost estimates for the environmental permitting efforts are based on the preparation of an EIS. For purposes of this report, the base routes will be the baseline estimates. Multiple alternatives to each of the base routes are also provided. Refer to the alternative corridor map in the map pocket for the locations of the routes. When referring to the map and in the route tables, please note for the link designations, the first two letters of each route delineate the overall route or area for a routing opportunity as follows: TS Tesoro Route Qc Quartz Creek Route EN Enstar Route AN Anchorage Municipal Area This Economic Section Report provides an overview of the project cost estimates, a summary of the estimates, and a detailed breakdown of the various costs.

SUMMARY OF ESTIMATES The Southern-Intertie has numerous.technical challenges regardless-of the route.. The following discussions reflect some of the more economically significant assumptions applied to the cost estimates. OVERHEAD LINES @ The overhead transmission structure types are steel guyed-X and single pole steel structures in accordance with the Design Section Report and detailed in Appendix A in this document. SUBMARINE CABLES ® The submarine cable estimates were performed based on double armor for the entire circuit length and embedding the cables. The decision to double armor and embed is based on the operating environment in the Turnagain Arm and discussions with Pirelli. Additional discussion on this information is presented in the “Submarine and Underground Transmission Cable” section of this document, Appendix B, and in the previously submitted Design Section Report. The recommended cable system at 138kV, except for the Bird Point crossing, is 2 - 3 phase flat type SCFF cables. Since this system provides for two completely independent 3 phase circuits, embedment of the cables may not be as important, since if one circuit fails, the line could continue to operate on the other circuit. Since embedment is estimated to add $14 per cable foot (0.7 - 2.5$M) to the installation cost, site specific Geotechnical investigation is recommended prior to finalizing a decision regarding embedment. At 230kV, 4 - 1 phase SCFF cables are estimated, with embedment. ®& The Bird Point Alternative was estimated using a different technology than the SCFF type submarine cable. We anticipate that it will be possible to set up in the Turnagain Arm and directionally drill towards either shore to place an HPGF type of cable system. PEI-HLY 55-0198 120293-01 (03/96) ab 2 ® After additional geotechnical investigations have been performed and the submarine, installation actually bid, we anticipate up to a 10% reduction (0.9 - 3.0 $M) in the cable material price. LAND UNDERGROUND CABLES > All anticipated underground high voltage cable installations are assumed to be XLPE type. This is reliable type of technology and has the lowest costs. SUBSTATION @ The substation estimates are based on the Design Section Report and the General Arrangements located in Appendix C of this document. @ The termination points for the Southern Intertie were selected for estimating purposes. Actual final terminal (substation) locations may vary in the Anchorage area. REACTIVE COMPENSATION @ Reactive compensation will be required for all scenarios of the Southern Intertie to facilitate steady state power transfer, dynamic stability during system disturbances and to control capacitance of high voltage submarine/underground cables. Additionally, construction of the new transmission facility will require compensation of the existing 115kV Intertie for the same reasons. Our cost estimates include appropriately sized devices for both new and existing facilities. The high voltage underground or submarine type of cables require shunt connected reactors. Generally speaking, the higher the voltage and the longer the cable run, the larger the reactor has to be to control the (higher) capacitance. Also, the existing 115kV Intertie would require shunt connected capacitor banks augmented by a Static Var Compensator (SVC) or a Thyristor Controlled Series Capacitor (TCSC) Bank. Estimates are provided for both scenarios; however, the TCSC offers superior steady state and dynamic capabilities and is the preferred choice. It should be noted, a significant capital cost savings of approximately $3M can be made by eliminating the TCSC, if it is determined that some underfrequency load shed can be tolerated. The extent of load shed is highly dependent on the generation mix at the time of a system disturbance and on the ability to be able to very quickly provide transfer trip of at least one Bradley Lake unit. PEI-HLY 55-0198 120293-01 (03/96) ab 3 ® The reactive compensation estimates are based on the previously submitted System Studies and Design Section Report and information detailed in Appendix D. ENVIONMENTAL PERMITTING @ Each of the three major potential route for the project present significant challenges to successfully securing a permitted route based on meetings with the public, affected agencies and a review of previous study correspondence. It has not yet been determined whether an EA {Environmental Assessment) or an Environmental Impact Statement (EIS) level of effort will be required to comply with NEPA (National Environmental Policy Act) requirements. Cost estimates included in this report are based on an EIS level of effort. ®@ As compared to the effort required for a typical EIS, the project will require additional studies or effort in the following areas (please refer to the Environmental Permitting Section for more detail): Anchorage Urban Study - Additional Data Collection Additional Public and Agency Meetings to Facilitate the Decision Process Additional Mitigation Studies PRE-CONSTRUCTION SURVEYS @ Prior to construction and potentially before agency approval on the selected alternative, a number of compliance studies are required. These include Section 106 (cultural) and Section 107 (biology). In addition, a Construction, Operation and Maintenance (COM) Plan would be prepared. The final element of environmental studies includes preparation of EAs (if needed) as well as other permits (e.g. Section 404). PEI-HLY 55-0198 120293-01 (03/96) ab 4 RIGHT-OF-WAY AND RIGHT-OF-WAY ACQUISITION r To secure the requisite project right-of-way, two major acquisition processes will occur: e Permit acquisition to secure CEA’s transmission line rights to exist on local, state, and federally administered lands; and e Private land easement acquisition to secure CEA’s rights to exist on private lands crossed by the transmission line. . The variation of project right-of-way and permit acquisition costs among the three primary ° alternatives-is a direct function of the agency lands crossed that require-permitting, as well as the amount of private land crossed by the route. The direct cost of subsequent land value of the lands encumbered by the easement on those parcels. Indirect costs are directly related to the number of parcels to be acquired, and the labor and expense costs associated with easement acquisitions. FIBER OPTICS Consideration for the installation of a fiber optic cable as part of the project was not requested until after the preliminary design was complete. The preliminary design and design criteria as presented in the Design Section Report do not provide for fiber optics. However, based on our experience with similar projects, we have estimated the cost of adding a fiber over the various routes and have summarized those costs below. Costs for the addition of fiber optics to the Project are not included in the overall Project costs as summarized elsewhere in this Report. If the addition of fiber optics is desired to be added to the Project, it is recommended that it be included in the requirements for the final design.

Significant substation modifications, including additional reactors would be required. The base route departs the Point Woronzof Substation via submarine cable and crosses to Fire Island. The cable makes landfall on the north end of the island, goes to overhead construction, then back to submarine type cable on the south end. -It again makes landfall near Point.Possession-on-the Kenai Peninsula. At-this point, the line has a small reactor station and proceeds down the coastline to Bernice Lake Substation via overhead with the exception of Captain Cook State Park, which is estimated as underground.

The underground continues to about Potters where it transitions into _ submarine type cable to cross the Turnagain Arm. The submarine cable makes landfall on the Kenai Peninsula near the Burnt Island Creek area. The submarine cable is then transitioned into underground type of cable to a point near Big Indian Creek. At Big Indian Creek there would be a transition station with reactors and go back to overhead construction the rest of the way to the terminus at Soldotna.

At Bird Point, alternative routes crossing the Turnagain Arm from Bird Point to the Snipers Point area and proceeding south along Sixmile Creek to rejoin the existing line near Hope Junction-have been estimated. The crossing-of the Turnagain Arm.at Bird point has been estimated for both overhead and submarine crossing alternatives. The submarine crossings has been estimated using directional boring techniques to enable the installation of an HPGF cable system. ROUTE DESCRIPTIONS AND COST ESTIMATE SUMMARIES The following tables more fully describe the base route for Quartz Creek Route in addition to the identified alternatives and their associated costs. Also, please refer to the Alternative Corridors Map located in the map pocket at the back of this report to assist the reader in identifying specific links that constitute the route and alternatives: PEI-HLY 55-0198 120293-01 (03/96) ab 1 TABLE QC 01 QUARTZ CREEK ROUTE Link Code | Total-Length Substation 138kV: One by extension of existing main and transfer layout. 230kV: New 230kV 4 Breaker Ring Bus.

These estimates are based on the preliminary designs presented in the Draft Design Section Report for this project. The estimates are organized by route and local alternatives similar to the route estimates contained in an earlier section of this report. Please refer to the route sections for link descriptions. The per mile line costs have been adjusted in some cases to allow for conditions not anticipated in the per mile line estimate. These cases include: e Link TE.D.40 across Fire Island. Costs have been increased because of access. e Links QC.C.30, QC.E.40, and QC.F.50 have been reduced because a reduced clearing effort is anticipated in these areas. e Links QC.D.40 contains a line item for temporary installation and removal of a line during construction of the double circuit steel line. Please note that guyed X structures were selected for cost estimating because they were practical for the locations in which they were applied and have costs which are comparable to wood pole H-frame and guyed vee structures. The type of structure chosen for final design will be determined after a detailed investigation of the route, agency requirements, and other factors.

PEI-HLY 120293-01 (6:51 PM3/11/96) th 1:/WAR/CHUGACH/SIP102.XLS 22 TABLE OH09 UNDERGROUND AND SUBMARINE CABLE INTRODUCTION Based on information obtained to date, the best choice available for submarine cable design in the harsh environment of the Turnagain Arm is a SCFF' cable with the exception of the Bird Point Crossing. For the Bird Point Alternative, we recommend using directional drilling to install a HPGF” cable system. We recommend that XLPE’ submarine cable not be considered because of the challenging cable operating environment of the Turnagain Arm. However, we do recommend using XLPE type cable for all land-based underground applications. Of the SCFF cable types, the least expensive is the flat three-phase SCFF cable configuration. This cable presents some unique capabilities, such as two completely redundant three-phase circuits, which may alter the recommendation for embedment pending additional geotechnical evaluation. As a result of our preliminary engineering investigations completed during Phase I of the Project, we are providing cost estimates based on the use of the following cable types: 2 - 3 phase flat SCFF cables, submarine type 4-1 phase SCFF cables, submarine type 3 - 1 phase XLPE cables SUBMARINE CABLE The cost estimates have been made assuming that double-armored cables will be embedded into the Arm’s bottom using a water jet assisted cable plow. The decision to use this method for the estimates is based on our current level of information about the potential crossings and the recommendations of Pirelli-Jacobson’s Brian Jacobson (see letter in Appendix B). We have also provided a non-embedded cost estimate for each of the cable types we considered by reducing each embedment estimate by $14.00 per cable foot. The embedment cost is for embedment only and the associated mobilization and demobilization of all required equipment is covered separately. ' SCFF - Self-Contained Fluid-Filled ? HPGF - High-Pressure Gas-Filled > XLPE - Cross-Linked Polyethylene PEI-HLY 55-0198 120293-01 (03/96) ab 1 There are possible exceptions to using embedment for selected portions of each alternative. Geotechnical and bathymetric evaluations could indicate that there may be areas where embedment is not needed. It may further indicate that additional armoring (rock armoring) is justified along part of the route where it is not feasible to embed the cables. Since significant field work is required and this data is not yet available, we have opted to consider direct embedment of double-armored cable along the entire route of each alternative to calculate the estimates. Based on the available information at this time, the reasons to embed cables are: e Scouring and abrasion of armor in the Point MacKenzie-Point Woronzof cable field has damaged armor on some of the existing cables, causing them to leak and subsequently be taken out of service. e Pirelli-Jacobson recommends the embedment of armored cables due to the environment, based on their experience in the area. e Embedment may reduce the risks of cables being damaged by anchors and moving boulders and changing Turnagain Arm bottom profile. e Buried armor suffers significantly less corrosion and wear. To determine areas where embedment is not practical or is unnecessary, we recommend that further evaluations of the sea bottom’s surface and subsurface be conducted. These include evaluations by side-scan sonar, sub-bottom sonar, geotechnical drilling, and investigation of the bathymetry of the Turnagain Arm. These evaluations will help determine where rock armoring is necessary along portions of each link. The reasons not to embed cable in certain areas include: e The bottom is too steep to use the embedding plow. e The bottom is so soft that the cable will embed itself. e Severe currents in the Arm cause the bottom to shift enough to uncover the embedded cable in a short time. e —_ Bottom conditions are too hard (rocky) to embed cable. e The additional cost of embedding already-protected (armored) cables may be considered excessive. ° Ice scour and/or boulder movement is so severe that embedment at a depth of 10 feet is not sufficient to prevent damage. Should the non-embedded approach be selected for part or all of an alternative’s length, the addition of rock armor over the double armor of the cables should be considered. Rock armor is an additional layer of armor consisting of wires that are typically larger in diameter than the wires of the underlying armor. The rock armoring is applied with a shorter lay than the normal armor wires. Its purpose is to provide additional protection against damage by external forces, such as anchors or boulders, and to support the cables when laid over obstructions or when bottom shifts suspend the cable over a portion of its route. This additional armor may double the weight of the cable and makes the cable stiffer and more difficult to handle. Rock armoring may be applied to selected sections of a continuous cable. PEI-HLY 55-0198 120293-01 (03/96) ab 2 The cost estimates are based on a 1,000-foot spacing of cables along the bottom. The Coastal Pilot (reference the Design Section Report) identifies an anchorage just north of Point Possession, near several of the possible cable routes. A final decision on the spacing should be made after the recommended geotechnical and bathymetric evaluations are completed. However, the actual spacing is expected to have little impact on the overall cost of the cable’s installation. Soil thermal resistivity studies conducted during the recommended geotechnical work may allow us to refine our judgment on using the 1,000 kCMIL copper cable selected for these estimates. These studies will also better define the shore landing conditions and the spacing of the cables. Better knowledge of these latter conditions may also allow us to refine the cable conductor size. LAND UNDERGROUND CABLES All estimates for cables installed on land have been made using a manhole and duct system which is typical and usual for this type of application. Additionally, estimates assume that cross bonding of the cable’s sheaths as described in the Preliminary Design Report. XLPE is the preferred insulation for land-based cables. This insulation material has proven reliability, is readily available, has the lowest losses and least maintenance requirements, and is the lowest capital cost. COST ESTIMATE SUMMARY Each of the following estimates is a compilation of the individual links and assumptions used to make up the cable costs of a particular route or local alternative. All cost estimates are in millions of dollars. Additionally, the following assumptions were used: e ___ Landfalls were assumed to be within 1,000 feet from water’s edge. e Geotechnical estimates includes marine survey, soil borings and soil thermal resistivity testing. e Labor and expenses related to installation techniques are included in the labor item on the mobilization/demobilization line item. e _ Burial conditions for embedment costs are assumed to be without boulders or other significant obstructions. Other items included in the section are a material pricing summary and a spreadsheet detailing the methodology to determine installation costs per cable foot.

Page 1 SUBSTATIONS INTRODUCTION Modifications will be required to existing substations to terminate the proposed Southern Intertie. For the purposes of this report, alternate substation estimates have been prepared to include the University, Point Woronzof and International substations in the Anchorage area and the Soldotna and Bernice Lake substations on the Kenai Peninsula. This section will present the applicable substation cost estimates for the modifications necessary to terminate the Southern Intertie. Cost estimates for each substation are based on the conceptual general arrangement drawings contained in Appendix C and other applicable information as contained in the System Studies and Design Section Reports. Equipment vendors were contacted for equipment prices and shipping costs and constraints. The equipment prices used in preparing the estimates are based on this vendor information and are f.o.b. site. Future plans and additions for the substations were considered and accommodated in these estimates to the extent possible. The preliminary designs have also considered the addition of switches where appropriate to allow future expansion with minimal outages. Additional land purchase and/or expansions of the existing fence will be required for all proposed substation modifications except for the 138kV options at University Substation. Land purchase prices are included in the right-of-way Section and were not included in the substation estimates. The following tables summarize the substation estimates by route, inclusive of labor, material, engineering, construction management, and 10% contingency.

PEI-HLY 55-0198 120293-01 (03/96) ab BERNICE LAKE SUBSTATION GENERAL The cost estimates for the Bernice Lake Substation are based on a new 115kV three breaker ring bus. The bus has been designed to not alter the existing access. The existing 115kV circuit breaker and voltage transformers will not be reused due to the length of outage required to perform the required modifications. The existing 115kV deadend structure and disconnect switch will be left in place and reused is shown in Figure SS-09, Appendix C. The existing yard must be expanded to the east for the addition of the Southern Intertie. Homer Electric Association (HEA) owns the property east of the substation to North Kenai Road. This area is adequate for the required modifications. 138kV OPTION A General Arrangement Drawing showing the proposed additions is shown in Figure SS- 09. The proposed arrangement requires that additional property, approximately 215 x 185 feet in size, be included in the substation fence. Refer to the more detailed cost estimates contained in Appendix C and the Design Section Report for more information on the specific equipment required. 230kV OPTION A General Arrangement Drawing showing the proposed additions is shown in Figure SS- 10, Appendix C. The proposed arrangement requires that additional property, approximately 235 x 185 feet in size, be included in the substation fence.

If the new station is not built at the time it is needed for the Southern Intertie, additional work will need to be done to the existing substation. The bay for the Southern Intertie can still be built in the location shown on Figures SS-11 and SS-12, Appendix C, but a strain bus would need to be constructed to connect the bay to the existing substation. Additional costs would be incurred for site work, fencing, grounding, control building, etc. that would not be necessary if the new station were in place. These costs have not been estimated. 138kV OPTION A General Arrangement Drawing showing the proposed additions is shown in Figure SS- 11. Cost estimates for the 138kV option assume that the proposed 138kV breaker-and-a- half station is in place. The general arrangement drawing of the proposed station furnished by CEA shows a bay designated for a future 138kV transmission line. As shown of Figure SS-11, this bay will be used for the Southern Intertie. 230kV OPTION A General Arrangement Drawing showing the proposed additions is shown in Figure SS- 12. Cost estimates for the 230kV option assume that the proposed 138kV breaker-and-a- half station is in place. The general arrangement drawing of the proposed station furnished by CEA shows a bay designated for a future 138kV transmission line. As shown of Figure SS-12, this bay will be used to connect to a 230/138kV autotransformer via an overhead strain bus. The 230kV portion of the station will be constructed adjacent to the proposed station and will require that additional property, approximately 250 x 55 feet in size, be included in the substation fence.

The design takes advantage of unassigned future positions where possible. 138kV OPTION A General Arrangement Drawing showing the proposed additions is shown in Figure SS- 13, Appendix C. Cost estimates for the 138kV option assume that the future 138kV bay shown on the general arrangement drawing furnished by CEA can be used for the Southern Intertie. 230kV OPTION A General Arrangement Drawing showing the proposed additions is shown in Figure SS- 14, Appendix C. Cost estimates for the 230kV option assume that an entirely new 230kV station will be built to the east of the existing station. Proposed changes to the 230kV portion of the station completely utilize all available land within the existing fence. Future plans include the addition of another 230kV line to ML&P Plant No. 2 and a 230/115kV autotransformer. The configuration of the proposed 230kV additions is not easily adaptable to accommodate the future additions. For this reason, a ring bus expandable to a breaker and half has been proposed as shown on Figure SS-13.

This bus has been designed to not alter the existing access. The existing station does not currently have circuit breakers to sectionalize the lines. The addition of the Southern Intertie requires the construction of a switching station for proper sectionalizing and protection. Insulators will be installed in the existing strain bus and the lines reconnected to the new station via a combination of rigid bus and strain bus as shown on Figures SS-17 and SS- 18, Appendix C. Shunt reactors, circuit switchers, and a switching structure are included in the cost estimates for the station. Costs for cable terminations are included in the submarine cable section. The existing yard must be expanded to the north to accommodate the new ring bus, the Southern Intertie termination equipment, and required reactors. 138kV OPTION A General Arrangement Drawing showing the proposed additions is shown in Figure SS- 17. Cost estimates for the 138kV option assume that an entirely new 138kV station will be built to the north of the existing station. and will require that additional property, approximately 190 x 300 feet in size, be included in the substation fence. 230kV OPTION A General Arrangement Drawing showing the proposed additions is shown in Figure SS- 18.

This section presents the cost estimates for each of the possible transmission line routes. Equipment vendors and turnkey/manufacturer’s were contacted to obtain equipment prices, shipping costs and related construction costs. The pricing information is used in preparing the estimates in this section. Land acquisition and/or new right-of-way will be required for all installations involving submarine/underground reactor installations. For the compensation of the existing 115kV line, additional property will be required adjacent to the existing right-of-way. Significant land acquisitions would be required both in the Anchorage area and on the Kenai Peninsula to accommodate Battery Energy Storage (BES) systems. Summary estimate sheets for all reactive compensation scenarios are provided at the end of this section. Detailed estimates and associated general arrangements are provided in Appendix D. The following tables summarize the reactive compensation estimates by base route. One alternative estimate to the Quartz Creek route is also included as the underground Bird Point Crossing requires additional compensation beyond the base route. No other routes require additional compensation due to routing alternatives.

PEI-HLY 55-0198 120293-01 (03/96) ab 2. SHUNT CAPACITOR BANKS The cost estimates are inclusive of utilizing shunt connected capacitor banks in 20 MVAR blocks. These are primarily for improving steady-state system operating conditions. As determined in the Systems Studies, the shunt banks must be augmented by a fast-acting device (Static Var Compenstors [SVC] or Thyristor Controlled Series Capacitors [TCSC]) on the existing 115kV Intertie. Accordingly, estimates for the shunt banks are included with either an SVC or TCSC. A general arrangement showing 2-20 MVAR banks with a 0-20 MVAR SVC is shown on Figure RC-01 and detailed in Table RC-01 in Appendix D. The configuration with the 0-40 MVAR TCSC is provided with a single 20 MVAR Shunt Capacitor Bank. Refer to Figure RC-02 and Table RC-02 in Appendix D. SHUNT REACTORS The cost estimates for the shunt reactor installations are provided for both 138kV and 230kV scenarios. In general, the reactors are placed at the terminus of the submarine/underground cables. The following table summarizes the required shunt reactor installations.

PEI-HLY 55-0198 120293-01 (03/96) ab 3 STATIC VAR COMPENSATORS The cost estimate provided for the SVC is included with the shunt connected Capacitor Bank, Figure RC-01 and Table RC-02 in Appendix D. The SVC operation for dynamic control is augmented by the more economical 20 MVAR shunt banks for the steady-state support. As described in the Systems Studies and Design Section Reports, the SVC provides dynamic stability during system disturbances. Significant control issues would have to be addressed to coordinate with the existing SVC installations. SERIES CAPACITOR BANKS The cost estimate provided for the Series Bank is included with a 20 MVAR shunt connected Capacitor Bank, Figure RC-02 and Table RC-02 in Appendix D. As with the SVC, a portion of the var support is more economically provided by standard shunt banks. Normally (mechanically) switched series capacitors can not be utilized for the Southern Intertie application due to response time and Subsynchronous Resonance considerations. A more detailed description and discussion is provided in the System Studies Report. Accordingly, this estimate included a TCSC Bank. This device provides sub-cycle response time and mitigates SSR concerns typically associated with series compensation. TCSC provides the best overall technical solution considering both steady-state and dynamic system requirements. BATTERY ENERGY STORAGE BES has the unique capability of providing full power circle operation. More detailed operational information is provided in the System Studies and Design Section Reports. Estimates for two systems (Anchorage and Kenai) project were provided by vendors. Together the BES systems estimates varied between $41 million and $51 million. These are rough budgetary numbers only. Significantly more study work would be required to refine the BES capacity specifications which could significantly influence the capital cost. Accordingly, detailed cost estimates are not available for this option.

This estimate is based on previous EISs successfully completed by Dames & Moore with similar issues. Initially, we estimated the cost based on estimated miles of alternatives. The three primary routes (Tesoro, Enstar, and Quartz Creek) equal approximately 275 miles total. There are approximately an additional 145 miles of local alternatives within the three primary routes. Accordingly, a total of approximately 420 miles of alternatives are to be evaluated in the EIS. For major EISs in rural areas, costs typically average approximately $4,500 to $5,000 per mile of alternative. Using this average per mile cost, we estimated the overall costs to be approximately $1.9 to $2.1 million. In addition, the Southern Intertie Project has a number of significant issues that will require additional studies or effort. These are: e Urban Anchorage: Typical urban studies vary in cost from $250,000 to $750,000. Because the Municipality of Anchorage has prepared a plan for utilities, we do not anticipate maximum costs for this study. Estimated additional cost is between $250,000 to $300,000. e The National Environmental Policy Act (NEPA) requires all alternatives to be evaluated equally. However, the level of data currently existing for the potential alternatives is inconsistent. For example, the Forest Service’s data are the most complete and are at the level of detail desired for a transmission line project EIS. For the remainder of the study area, data gaps exist for soils, vegetation, visual concerns, etc. An additional $150,000 to $200,000 is anticipated for data collection. e Typically, after completing the initial feasibility or alternative identification studies, a solution for most utility projects becomes obvious. However, for the Southern Intertie Project, a combined least-impact and least-cost preference has not yet appeared because of agency issues and submarine crossing conditions. This will result in a difficult decision process with numerous decision meetings with the client, agencies and interested parties, graphics, and data management. Estimated additional cost ranges between $100,000 and $150,000. PEI-HLY 55-0198 120293-01 (03/96) ab 1 The difficulties or agencies with significant issues are as follows: - State Parks - Forest Service - US. Fish and Wildlife Service - Corps of Engineers (404 permits) - Native Corporation Lands and Private Lands (Soldotna and Kenai areas) The primary concerns include visual, wilderness, recreation/tourism, and wildlife habitat. The concern of federal and state agencies is the management of these resources and the potential impact of the transmission line on them. Since there is no clear resolution of these issues for the primary routes, we will need to conduct major mitigation studies in locally sensitive areas. Visual analysis will include numerous simulations and visibility analyses. Typical wilderness studies will include user identification and areas of potential impact prior to making mitigation recommendations. The level of analysis for recreation and tourism will be generally confined to mitigation of visual and physical impacts, while wildlife habitat may be somewhat more complex. The cost for additional visual and recreation/tourism analyses is estimated to be $100,000 to $150,000. The following table summarizes the overall environmental cost estimates. Urban Study 250,000 300,000 Additional Data Collection Decision Process Additional Mitigation Studies 100,000 150,000 Total Estimated Cost Range’ $2,500,000 $2,900,000 Anticipated Cost ($) Potential Cost ($) 150,000 100,000 200,000 150,000 ' Estimated costs do not include client, legal counsel, or agency involvement (cost reimbursement). PEI-HLY 55-0198 120293-01 (03/96) ab 2 Additionally, pre-construction surveys, monitoring during construction, and compliance planning are needed”. Their cost is estimated as follows: The work in preparing the EIS is detailed in the following sections. ENVIRONMENTAL IMPACT STATEMENT The general technical approach, including the environmental studies and preparation of the EIS, is described below. It is important to note that we are assuming an EIS will be required, although there is always the potential to complete an environmental assessment (EA). Typically, this kind of work can be organized into seven main groups of activities, as shown below. Terminology may vary depending upon the lead agency. 1) Work Scope 2) Scoping 3) Inventory 4) Impact Assessment and Mitigation Planning 5) Preferred Route(s) Selection 6) Draft EIS (DEIS) 7) Final EIS (FEIS) A geographic information system (GIS) will be used to assist in the environmental analysis. This system will provide the ability to summarize the voluminous environmental data, assist reviewers and decision makers in identifying and assessing specific impacts, and compare routing alternatives. GIS applications will include: e __ Digitizing of resource inventory data as collected and recorded on maps by resource principal investigators e Conversion of mapped resource data to a digital database format > These estimated costs are not based on a final route and will need to be reviewed during the EIS phase. > Cultural and biological surveys may be required during the EIS phase. PEI-HLY 55-0198 120293-01 (03/96) ab 3 e Development of impact assessment models to evaluate how construction and operation of the proposed project would affect resource values and features e Data report and presentation graphics, inventory and impact maps at various sizes and scales WORK SCOPE Dames & Moore would assist in the identification of a federal lead agency, including preparation of documents (e.g. preliminary right-of-way application, etc.), and initial agency meetings. The project’s preparation plan required at the initiation of an EIS will contain the overall scope of work, including management structure and responsibilities, technical approach for the environmental studies, methods for conducting the resource studies, and schedule. This preparation plan will be approved by the agencies. A public involvement program would also be developed and is expected to include the agency interdisciplinary team, newsletters, public open houses, working groups, and perhaps a project information line. In addition, we will assist the lead federal agency in preparing the Federal Register notice. SCOPING Several agency and public scoping meetings would be conducted. Prior to initiating the environmental process, the project team will meet with other federal agencies, which have the potential to become cooperating agencies for the EIS, to inform them of the project, discuss their issues and concerns, and invite their participation in the project. Follow-up meetings with the agencies will be conducted during scoping and throughout the project. The lead federal agency will execute interagency agreements with the cooperating agencies. The lead federal agency would prepare a Notice of Intent to prepare the EIS for publication in the Federal Register and establish the dates and locations for the public scoping meetings. Public scoping meetings would be conducted at various locations within the study area. The purpose of the meetings is to introduce and describe the project, explain the purpose of and need for the project, describe the environmental studies and public planning to be conducted as part of the environmental process, and solicit comments. The lead federal agency would conduct all scoping meetings. CEA, or its representative (e.g. engineering consultant), will participate by presenting the project description and purpose and need. Dames & Moore will present status of initial studies and will prepare displays, including project map and flip chart visual aids, handouts, and sign-in sheets. Dames & Moore will document and summarize the proceedings and prepare a report on the scoping process and results. Potential changes to the scope of work will be documented. A project mailing list would be established and maintained throughout the project. Dames & Moore would prepare fact sheets to send to all addresses on the mailing list and would prepare PEI-HLY 55-0198 120293-01 (03/96) ab 4 news releases for all media within and nearby the study area, including newspapers and radio and television stations. A plan of development describing what can be expected for construction, operation, and maintenance will likely need to be prepared early on, depending on the lead agency’s requirements. INVENTORY Specific to the alternative corridors, available resource data previously not obtained through secondary sources (i.e., existing maps, databases, published and unpublished reports) and agency contacts will be researched and secured. The collection of data will be systematic and well documented. Dames & Moore will provide the resource study team with corridor base maps and a data documentation packet of standard forms to record the data sources. For example, information about the original scale and sources of data, assumptions used during collection, formats, dates, and additional sources will be part of the data documentation. Important to this procedure is the documentation of variations in data resolution and accuracies in order to understand any limitations of the data. These procedures will provide a means to ensure the applicability of the data and the validity of their sources. Preliminary base data initially will be developed for each alternative corridor based on refinement of the secondary data, supplemented by aerial photo interpretation and additional map studies. Environmental data will then be reviewed in the field, verified, and mapped in final form supported by graphs and tables as appropriate. The environmental resources to be addressed, at a minimum, include: Air Resources Earth Resources Water Resources Biological Resources Land Use Visual Resources Socioeconomics Electrical Effects Cultural Resources (prehistory, history, Native American concerns) It is important to note that the inventory study area or corridor widths will vary by resource depending on the needs and concerns for each resource study. For example, visual resources may be affected up to two miles from an assumed centerline, while effects to earth and water resources may be evaluated approximately one-half mile from the assumed centerline. PEI-HLY 55-0198 120293-01 (03/96) ab 5 Once plots have been completed for each resource study, the resource study teams will input and verify data at an appropriate scale. A refined database for corridor level assessment will be constructed. Corridor base maps created on GIS/Computer-Aided Drafting and Design (CADD) will include roads and other features that allow registration. Dames & Moore will digitize all maps, provide check plots to scale, complete all editing changes, correct maps and cut into grid cells. Each corridor may be subdivided at an appropriate size and, when complete, will serve as the maps for digitizing. Each resource study team will be responsible for checking the accuracy and edge matching of data sets within the corridors. As necessary, corridor information will be produced on an overall map or separately. Technical reports will be produced and given to the lead and cooperating agencies as documentation for the EIS. Presentation maps will be prepared at the appropriate scale. IMPACT ASSESSMENT AND MITIGATION PLANNING The objective of the impact assessment and mitigation planning process (IA/MPP) is to conduct an interdisciplinary analysis of the potential environmental impacts and plan effective mitigation within the alternative corridors. Concurrent with the refinement of the environmental database, we will implement the IA/MPP. The methodology will be reviewed by the ID team, which includes the project participants, so that pertinent issues and concerns are addressed. The ID team will meet at key times during this task to understand the methodology and results. Potential environmental consequences (impacts) are based on the environmental effects that would result from the construction and operation of the transmission line along the alternative routes. Through the use of the [A/MPP, the potential direct, indirect, and cumulative impacts, the interrelationships (cause and effect) of impacts (beneficial, adverse, direct, indirect, local, or regional) will be determined. Determining impact significance is probably the most important and difficult part of impact assessment and will be determined through a systematic process of defining criteria for “thresholds” beyond which impacts are considered significant. Criteria for thresholds will take into account the magnitude, incidence, intensity, duration, and interrelationships of impacts and regulations. The criteria will be developed based on data collected, issues and concerns expressed, and relevant agency policy. Requirements for access involves where and to what extent roads would have to be built or upgraded to construct the proposed project facilities for each alternative corridor. Dames & Moore will assist POWER in determining where existing roads are sufficient or would require upgrading, and where new access roads would have to be constructed. Potential vegetation clearing will also be estimated. Specific impacts of each resource will be documented in the technical reports. The technical reports will be accompanied by data tables that indicate the location and description of specific resource features and values, initial impact levels of these resources, mitigation measures PEI-HLY 55-0198 120293-01 (03/96) ab 6 recommended to reduce impacts, and residual impacts expected following mitigation. The technical reports will be reviewed and approved by the ID team. PREFERRED ROUTE(S) SELECTION Ranking the alternatives and selecting the “environmentally preferred” alternative or alternatives (or corridor) are the final steps before the preparation of the EIS. Ranking and comparing the alternatives are important in understanding the relative impacts of each. A multi-objective decision-making process will be used to evaluate and compare the environmental considerations inherent to the study area. Each resource study team (e.g. land use, biological, etc.) will conduct comparisons or rankings of the alternative corridors. These comparisons will be used to synthesize “cross discipline” rankings of all alternative corridors. The purpose of rankings is to develop an environmental ordering of all corridors under consideration. This comparison of corridors uses information and judgments rendered within each resource study. These data are organized around goals, of which the most important for the EIS is the identification of the environmentally preferred alternative or alternatives. All corridors will be ranked in order of environmental preference. Routing preference will be based on review of generalized impact levels, significant unavoidable adverse impacts, and other pertinent descriptive and impact data. Agency and public comments received through the public contact and information program also will be considered. The lead agency and cooperating agencies will identify the agency-preferred alternative or alternatives for inclusion in the EIS. Critical information from the project proponent is typically considered by the lead agency in its decision. DRAFT EIS (DEIS) The format of the DEIS will be in accordance with the Council on Environmental Quality regulations 40 CFR 1502.10 for preparation of an EIS. A preliminary DEIS will be prepared for review and approval by the lead and cooperating agencies. The schedule for preparing the preliminary DEIS will be carefully synchronized with the schedule of the environmental studies in order to ensure its timely completion and submission. For example, the chapter on the affected environment will be written after the resources inventory material has been developed. The chapter on environmental consequences will be completed after the impact analysis has been determined. Other special sections and appendices will be compiled throughout the preparation of the preliminary DEIS. The preliminary DEIS will be reviewed by the lead agency, CEA, and cooperating agencies. Review comments will be returned for incorporation by Dames & Moore into the final DEIS. Review meetings will be scheduled to clarify all comments on the report. Dames & Moore will then finalize the DEIS for final approval by the lead agency and CEA. PEI-HLY 55-0198 120293-01 (03/96) ab 7 Dames & Moore will revise the report, if needed, and submit the final camera-ready DEIS to the lead agency. The lead agency will file the DEIS with the EPA, prepare and issue the Federal Register Notice of Availability, and distribute copies of the DEIS to interested parties. During the DEIS review period, the lead agency, with assistance from Dames & Moore, will conduct public hearings to receive comments on the adequacy of the DEIS, make arrangements for the hearings, prepare notices and media releases, and conduct the proceedings. The representatives of the Dames & Moore project team will attend the public hearings and provide input as needed. Preparation of the environmental presentation materials by Dames & Moore will be closely coordinated with the preparation of technical and engineering information by POWER. FINAL EIS (FEIS) Following the public review period, the comments received will be reviewed by the lead agency, cooperating agencies, CEA, and Dames & Moore. The responsibility for developing appropriate responses for inclusion in the FEIS will be assigned by the lead agency. Presumably, Dames & Moore will prepare responses to all comments on the environmental studies while those related to the purpose of and need for the project, system planning, and engineering design will be completed by CEA. Following the development of the responses, the comments and their corresponding responses will be incorporated into the preliminary FEIS and submitted to the lead agency, cooperating agencies and CEA for review. Based on the comments from the review, Dames & Moore will prepare the FEIS for final approval by the lead agency. The lead agency will file the FEIS with the EPA and prepare and issue the Federal Register Notice of Availability. Dames & Moore will also prepare and issue media releases and newsletters, and distribute the FEIS to interested parties. At the close of the FEIS review period, the lead agency will prepare and issued the Record of Decision. A plan amendment may be required by a land managing agency, such as the Forest Service or Bureau of Land Management. Plan amendments are typically required when a preferred route does not utilize an existing or planned utility corridor documented in the Forest Plan or Resource Management Plan (Bureau of Land Management). PRE-CONSTRUCTION / MONITORING Prior to construction and potentially before agency approval on the selected alternative, a number of compliance studies are required. These include Section 106 (cultural) and Section 107 (biology). In addition, a Construction, Operation and Maintenance (COM) Plan would be prepared. The final element of environmental studies includes preparation of EAs (if needed) as well as other permits (e.g. Section 404). PEI-HLY 55-0198 120293-01 (03/96) ab 8 RIGHT-OF-WAY AND PERMIT ACQUISITION INTRODUCTION In order to secure a right-of-way along an approved route, significant permitting and acquisition of private easements will be required. Because of the complexity of local, state, and federal agency permits, as well as the need to resolve concerns of private landowners, the right-of-way acquisition process will require close coordination among project team groups, i.e., CEA personnel, project management, Dames & Moore, design staff, and the right-of-way personnel. Therefore, costs for right-of-way acquisition do not accrue only to right-of-way personnel. For detailed information about the project land status and anticipated permitting process refer to the Draft Lands/Regulatory Section Report. Cost information presented here was derived from researching the land status and property values along the core route for each of the three primary study corridors and their local alternatives. While the permitting requirements may not vary for a route selected anywhere within the boundaries of a study corridor, the number of private parcels may vary from one side of the corridor to the other, thereby affecting the cost of easement acquisition. PERMITS The three primary study alternatives, as well as their local alternatives, have many common permit requirements. Costs presented for permitting include title services, appraisals, and the assembly of exhibits and submission of the permit applications. Also included are costs to track the permit through the approval and granting process. Costs for conducting the appropriate environmental compliance associated with permits are covered in the costs for the EIS and pre-construction monitoring. Anticipated permit applications required include: Kenai Peninsula Borough Right-of-Way Permit Alaska Department of Fish and Game Title 16 Stream Crossing Permit Alaska Department of Fish and Game Title 16 Waterways Permit Alaska Department of Natural Resources Right-of-Way Permit Alaska Division of Governmental Coordination Coastal Zone Consistency Permit Bureau of Land Management Grant of Right-of-Way Alaska Department of Natural Resources Tidelands Lease Municipality of Anchorage Right-of-Way Easement PEI-HLY 55-0198 120293-01 (03/96) ab 1 e State of Alaska (DNR), Division of Parks and Outdoor Recreation Right-of-Way Permit Corps of Engineers 404 and Section 10 Permit State of Alaska, Mental Health Trust Lands Permit Alaska Department of Transportation and Public Facilities Utility Permit U.S. Forest Service Special Use Permit Alaska Railroad Corporation Crossing and/or Easement Permit Kenai River Special Management Area Permit Alaska Department of Natural Resources Tidelands Right-of-Way Permit RIGHT-OF-WAY ACQUISITION Land Field Services of Anchorage researched public records to determine estimates of parcels crossed by the various routes. Those sources were also used to gain a planning- level estimate of land values that could be used to derive easement costs. These data sources included: e Municipality of Anchorage Assessor and Recorder records for plats and assessed value; e Motznik Title Service for urban area land values; e Kenai Peninsula Land Management Officer, Assessor; and GIS Manager for maps, plats, parcel and cost information; and e Land Field Services, via past CEA project work, with an extensive in-house data base for lands crossed by the Quartz Creek 115kV Line. An individual parcel-by-parcel examination of location and cost relative to each specific route link was beyond this phase’s work scope and, accordingly, was not conducted. In- depth title searches and appraisals would be conducted for each parcel affected by the ultimately selected route within which right-of-way acquisition would occur. In some cases, particularly in the Anchorage area, the nature of readily available parcel information is such that parcel counts may be incomplete. Again, after a route selection process is complete, this would require an in-depth title search to provide the level of detail necessary to proceed with easement and permit acquisition. The records examinations described above reveal parcel counts for the core, or primary routes as follows: e Tesoro Route - 105 parcels between Point Woronzof and Bernice Lake; e Enstar Route - 58 parcels between the International Substation and the Soldotna Substation; e Quartz Creek Route - 93 parcels between University Substation and Soldotna Substation PEI-HLY 55-0198 120293-01 (03/96) ab 2 In our analysis, it has been assumed for the links that parallel an existing road, highway, railroad, or other identified public utility corridor, the transmission line would be sited within the existing utility corridor. The rationale for this assumption is based on constraints of the Alaska eminent domain statutes. Those proceedings do not allow a utility to condemn private lands if a public utility corridor is available for the proposed use. Therefore, in those cases, right-of-way acquisition costs would accrue to permitting only, with no costs required for acquiring private lands. An examination of land status in the vicinity of landfall alternatives for submarine cable shows that nearly all are owned or administered by federal or state agencies. Therefore, the costs for reactive compensation stations site acquisition is covered within the appropriate permitting process. If an alternative landfall is chosen in the Klatt Road area, it is likely that private property would have to acquired for the landfall facilities. It is estimated that land values in that area are $152,000 per acre. Costs for acquiring this site are included in the costs for this alternative. As it may become desirable to expand the University Substation, an examination of land status to the east of the substation was made. A suitably sized parcel is privately owned in that area. Land values in this vicinity are currently approaching $200,000 per acre. Approximate land values in other project areas are as follows: Soldotna, $10,000/acre Point Possession, $20,000/acre north of Captain Cook State Park, $3,000/acre south of Captain Cook State Park, $5,000/acre rural lands along the Quartz Creek Route, $1,000/acre These costs form the basis for the direct cost of purchasing the easement. In the case of CEA’s easement payment policy, the landowner would receive 100% of the fee value of his property for the area encumbered by the easement. Costs for acquiring private rights-of-way include: title services appraisal services ($750/parcel) easement surveys and descriptions ($600/parcel) document preparation negotiation recording file transfer/close-out PEI-HLY 55-0198 120293-01 (03/96) ab 3 The above listed costs form the basis for determining the indirect cost of right-of-way acquisition. Essentially, these costs are associated with the labor and expense of acquiring the easements. It is estimated that the total indirect cost per parcel for acquiring easements on this project would be $3,350. The total cost for right-of-way acquisition for each primary route and local alternative includes direct, indirect, and permitting costs.

Box 1066 sitet Hailey, Idaho 83333 Attn: Mr. Jack Hand Re: Submarine Cable Circuit Turnagain Arm - Cook Inlet, Alaska Dear Jack, We have completed our rough estimate of installation costs for (4) single conductor 138kV oil filled submarine cables at (4) crossings in Turnagain Arm - Cook Inlet Alaska. We believe it would be in the customers best interest to embed these cables under the sea bed for the total length of the crossing. The embedment of the cables is based upon a jetting method utilizing high pressure water being applied to a cable burial machine. The cable is laid through the sled and is placed at a pre-determined depth via a “stinger” located on the burial machine. It is also recommended that double armor be applied to the outer sheath of the cable for added protection and longer life. The armor should be the same lay for ease of handling. We have broken our estimate into two categories including just laying the cables on the sea bed and laying and burial of the cables. ; We appreciate the opportunity to work with you and should you have any questions please do not hesitate to contact us.

REGARDING YOUR FAX DATED JANUARY 9. 1996 Dear Mr. Aabo, In order to respond to your fax in dus time, I will submit a rough estimate of a similar cable with a slight difference in the cross section (750 MCM instead of 1000 MCM). The cable that we propose will be SCFF (self contained Suid filled) cable as per attached cable technical data with double armor. AS REE Oe Sorte PELE AS , The cable will have a polypropylene yarn serving and it will be mamufactur¥d th 8 continuous length. The budgetary price for the cable ex-factory Naples (Italy) is $160 USD / ft. To the above cost, you will have to add the import duties and the transportation cost. Please also note that we have proposed a double armor cable because as you mentioned in some areas there is rocky hard bottom and the cable burial is questionable from s technical and econoraical point of view. We have to inform you that our company owns different burial machines that use the jetting method but all are usable in sandy/mud bottoms, ie. jettable bottorn, and we do not have available machine for trenching in rocky bottom. Should you require an estimate for construction, please keep in mind the above. 5955 2th Avenue N.W."**Seatile, WA 98107" USA.
