Mayor TELECOPIER (907) 276-2961 March 2, 1987 Don Shira Alaska Power Authority 701 E, Tudor Road Anchorage, AK 99503 Dear Don: We have reviewed the Preliminary Report on the Feasibility Study of the Anchorage-Kenai Intertie presented by Power Engineers, Inc. on February 17, 1987. We feel both that they did a very good job on the study and that the presentation was professional and infor- mative. Our comments relate to the preferred route selection and how we feel the study should proceed. First, we feel that any upgrade of ‘the existing line between Anchorage and Kenai would not provide acceptable reliability for the interconnected system. This, combined with the significant line loss and line loading problems identified by PEI at 138 kv, and with the fact that the estimated cost for upgrade of the existing line to 230 kV exceeds the estimated cost to construct a new line in two of the remaining scenarious, leads us to recommend that all scenarios having to do with upgrade of the existing line be eliminated from further consideration. Second, we feel that the Beluga Alternative should also be elimi- nated from further consideration due to technical difficulties associated with the underwater crossing and potential power flow problems between Beluga and Anchorage. In addition, PEI's environmental consultant has indicated that they feel there may be significant permitting problems associated with routing this alternative. It would appear that any one of the four remaining alternative line routings would satisfy the requirements that we have iden- tified from a technical perspective, and that none of the four has any indication that significant environmental or routing problems are expected to be encountered. We, therefore, recommend that one of the lines following the Enstar routing be pursued for further study at this time. If, in the course of further atudy, it is determined either that this alternative is not technically suf- ficient, that environmental concerns are present that are expected to be fatal, or that this alternative is expected to be signifi- cantly more expensive than one or more of the remaining three, we would recommend that the Tesoro routes be pursued. We see no PROVIDE FOR TOMORROW, SAVE ENERGY TODAY. v= 22s 733 cos 2 March 2, 1987 Don Shira Page 2 problems associated with termination of the line at Huffman substation and initial operation at 138 kV, but would like to stress that we feel that all construction should be 230 kV for future operation. Further, we would like to suggest that the estimates associated with the Enstar route in particular reflect reasonable costs to thoroughly develop the Potter Terminal Station for maximum aesthetic consideration through proper landscaping. Finally, it is our recommendation that the study proceed as origi- nally outlined, with a preferred alternative identified by the utilities and the Power Authority and studied further by PEI. We would, however, like to see the work that has been done to date on all alternatives included in the Final Report so that if there are questions about the alternatives not selected as the preferred routing, the background information can be easily provided. Thank you for the opportunity to provide comments, and once again, our compliments to PEI for a job well done. “nike LM] Chief Engineer Municipal Light & Power MEM/TL/csn u n a + oja11-87 : a ' t ire o a or w ur @ & 1 " r u < 1987 ELECTRIC ASSOCIATION.

Box 190869 Anchorage, AK 99519-0869 Subject: Anchorage-Kenai Intertie Feasibility Study February 17, 1987, Meeting Summary Dear Mr. Shira: The following are the comments of Chugach Electric Association, Inc. on the content and written summary of the meeting on the morning of February 17, 1987, between Power Engineers, Hart Crowser and the Railbelt utilities. 1. On Page 2 of the meeting summary, cost matrix development is mentioned for ranking the routes with a capacity ranking included. We are not aware of what is meant by capacity ranking and ask that it be defined further. Chugach's concern with capacity is to identify the costs associated with construction at 230 KV for any new routes, although 138 KV may be determined as adequate for transfers during the time frame of the study. The cost savings of initial energization at 138 KV may not be justified if the incremental cost of 230 KV energization is small. Furthermore, if 138 KV is ultimately chosen, a difference in upgrade costs between routes may be a factor in selection. Ze A difficulty and time requirement factor for both permitting and right-of-way acquisition should be included in the ratings. As the meeting summary stands now, only difficulty is mentioned. Sa With regard to the lack of estimates on the Cook [Inlet crossing from Kenai to Beluga, a detailed discussion of the recommendation against such a crossing by Pirelli and Jacobsen should be included in the report, along with all analysis performed to date by Power Engineers and Hart Crowser. 4. Regarding the Huffman Substation, Chugach stated at the meeting that room for a breaker and transformer at the site Don Shira -2- March may be available at the 138 KV level, but that Power Engineers should plan on extensive site work that would be required for such installation. Recent developments in ordinances on substation landscape requirements in the Anchorage Bowl may preclude the use of Huffman for the Intertie or any other expansion, however, and must be considered. Hart Crowser has been notified of the proposed landscape ordinance. 5. Any Intertie construction at International will require a new substation, requiring extensive site preparation in addition to the landscaping requirements. 6. It was requested by Chugach that minimum load transfer cases be investigated to establish the amount of reactive compen- sation required at the cable terminals. This was apparently omitted in the original studies. Chugach also suggested that close attention be paid to cable terminals as it is possible that very compact terminals will be required due to environmental or aesthetic concerns, Te Chugach had asked Power Engineers to evaluate the capability of the existing substation at Bernice Lake to hold a 138 KV or 230 KV substation as the existing location may require extensive reconstruction and land acquisition.

No one route of those suggested stands out as the best ror Homer Electric. We thererore orrer the tollowing brier comments on each route and will be present at tne meeting on Feb. 1/7 to discuss them with vou. 1. Existing Route Homer Electric has considered this route to be undesirable because or the reliability experienced on the present line. This route is over rough, mountainous terrain and would be in our opinion the most difficult route to construct a new line. <. Enstar Pipeline Route This is considered a desirable route by Homer Electric as it traverses a area already being used by a pipeline. is not subject to adverse weather conditions and would require the shortest submarine crossing. This route will. if selected, tie the ends of both the existing and new line between the Kenai Peninsula and Anchorage together thereby not ortering the highest degree of relability. Tesoro Pipeline Route This route 1s not considered a desirable route because of the extreme weather conditions experienced by Homer Electric along the route and because ot the long submarine crossing coming up in the area of the airport. In regards to the extreme weather, this area is one of the few areas were lines designed tor heavy loading conditions have actually experienced such conditions. uw 4. Forelands/Beluga Substation Route The increased realibility by connecting this new intertie line with the Beluga Station makes this route desirable to Homer Electric. This route would however require the crossing of the Cook Inlet in an area known tor extreme tidal conditions and may make the submarine very difficult. In summary Homer tlectric would suggest the route selection be narrowed to the Enstar and Forelands/Bbeluga proposed routes. we will be wiliing to discuss these issues at the Feb. Lv meeting.

Project Manager Hart Crowser, Inc. 2550 Denali Street Suite 900 Anchorage, Alaska 99503 Reference: Anchorage/Kenai Transmission Intertie Feasibility Study-Preliminary Route Options Dear Mr. Gill: Municipal Light and Power has reviewed each of the four possible transmission line routes; Existing, Enstar, Tesoro and Beluga, and finds no reason at this time to recommend exclusion of any single one from further consideration. The Beluga route, which received little attention during preliminary discussions prior to commencement of this study, appears to be one in which consideration should be sustained pending further underwater analysis and power flow analysis. We are obviously concerned about a new underwater route not previously used. The Tesoro route has us concerned from the standpoint of having the longest sub- marine route plus the difficulties likely in going through the Anchorage Airport area with additional underground cables. We also understand that the overland route of the Tesoro alignment is one which currently experiences weather related problems. Even so, the route is a viable one. The Enstar route will be facing problems with the Potter Marsh crossing as well as problems on the Moose Range, but still appears to be the leading contender in our mind. The Existing route should remain in the running, but we have concern both from the standpoint of ending up with a single transmission line to the Kenai as well as problems with this circuit being out of service for extending periods of time during any type of reconstruction. We would continue to urge you to thoroughly document your review process par- ticularly as options are narrowed to three alternatives and then selection of the preferred route. We look forward to meeting on the 17th of February to further discuss your progress. Mam Sincerely, Mike Massin Chief Engineer cc: T. Stahr,ML&P D. Shira, A.P.A. J.

Box 1066 Haily, Idaho 83333 Subject: Anchorage-Kenai Transmission Intertie Feasibility Study Dear John: We have reviewed the Preliminary Report and offer the following com- ments: Comments from Municipal Light and Power (ML&P): 1. ML&P recommend that the Enstar 230KV alternative be selected as the preferred route for more detailed studies leading to the construc- tion of the project. ML&P also recommend that the actual alterna- tive between Huffman and International not be selected until more study work is completed. 2. ML&P is requesting that the "area interchange" specific designa- tions as to exactly how much generation either ML&P or Chugach Electric Association (CEA) may provide, be left in the generic sense as was agreed to at the first assumptions meeting held at the Alaska Power Authority. ML&P understand that it was probably necessary to designate biased weightings to one of them for purpos- es of running certain cases, but ML&P want to make it absolutely clear that ML&P is not endorsing some type of actual method to ultimately supply generation based on these numbers. This informa- tion is on pages 2-6 through 2-10 of the report. This change from the initial assumptions meeting was made without our approval. 3. ML&P also insist that more backup be furnished from Pirelli con- cerning the reasons why Pirelli indicates that a submarine crossing is not feasible on the Beluga route alternative. It would be helpful if they would cite technical or other reports which may have been done by oil companies or others to support their conten- tion. 8851/DD20(1) PO.

Box 190869 704 East Tudor Road Anchorage, Alaska 99519-0869 (907) 561-7877 Mr. John McGrew April 22, 1987 Page 2 — ML&P is concerned about the 180 MVA capacity of the submarine crossing of Turnagain Arm. Shouldn't this be more in the area of 250-300 MVA? ML&P continue to be concerned about the portions of the cost estimates specifically related to substation and switchyard site development. Also, it is absolutely critical that estimates include costs for landscaping and other aesthetic enhancements which will be required at all Anchorage area substation locations, particularly the Potter Marsh location terminal site. One sure way to lose support from the community and other concerned parties is to not provide for aesthetics. If the estimates for permitting and right-of-way acquisition are at all pessimistic in nature, as far as the time elements, ML&P would encourage the consultants to be more optimistic. It would be a shame if these lengthy time frames end up being used against the Power Authority and the utilities as an excuse to delay or stop the project from coming on-line in the time frame of the related Bradley Lake Hydroelectric Project. ML&P's experience on this in the past has been that if you tell reviewing agencies that "consid- erable" amounts of time have been allocated, considerable amounts of time will be utilized, often times unreasonably. ML&P wholeheartedly agree with the consultant that action on permitting and right-of-way acquisition be initiated as soon as possible to allow this project to come on-line in conjunction with Bradley Lake. Attached is listing of minor "housecleaning" items involving typographical errors, etc. for your use. Golden Valley Electric Association comments on load flow is attached. Comments from Alaska Power Authority: Executive Summary needs to be a strong document. Introduction should have examination of different cases, 230KV vs. 138KV. Is there a need for second intertie? More discussion on how PEI arrived at Enstar route. Explain term "complexities" for Enstar and Tesoro route. Permitting and acquisition costs are about same between two routes. Explain the differences. Explain paralling existing line is not possible. 8851/DD20(2) Mr. John McGrew April 22, 1987 Page 3 Describe what a feasibility type estimate is. Soldotna Substation is not expandable. Comments from Chugach Electric Association: CEA strongly feels that the PEI has to review the station cost estimate as for the accuracy.

In view of the above adverse conditions, it is not considered practical to install and operate a submarine cable in this route. Tesoro Route The Tesoro Route is preferred. The water depth is adequate to minimize problems due to ice formation and movement. The soil stability is good as determined from pipeline construction emperience. Current flow and tidal action are within working limi¢s. Mar 11,87 10:01 Mr. John McGrew March 10, 1987 Page Tow Enstar Route The 28 foot tides and resultant tidal water flow forces water into rivers with reverse movement as the tide subsides. The effect is exceptionally poor soil stability increasing the difficultly and cost of burial of the cable. Budgetary Costs and Physical Properties Pumping Plant The weight and dimension of each self contained pumping plant structure are as follows: Dimensions: 24.5 feet in length, 9.2 feet wide and 12 feet in height Weight Without Oil: 30,000 lbs Weight With Oil: 67,500 lbs Cost: $840,000 for two pumping plants including freight and handling to Anchorage Alaska.

The reservoir oil feeding system previously described for the land cables is valid for a cable run of approximately 2 miles. For a cable run of up to 4 miles, it will be necessary to install a buried oil pressurization system consisting of 6 reservoirs at the midpoint of the circuit. In order to feed oil into the cable at this location, stop joints will be required.

Installation The installation cost for the Enstar or Tesoro Route submarine cable, including a spare cable, is estimated at 8.5 million dollars. The cost includes the following items: Rigging Transportation Unloading the cable in Seattle Prelay survey Mobilization of the laying barge Loading of the cable onto the laying barge in Seattle Movement of the laying barge to Anchorage Laying of four cables Landing of the cables to the terminal locations The cost of embedment of the four cables for the entire route in 2 to 3 m depth of soil is estimated as 6 to 9 million dollars. Although the cost will vary with local and environmental conditions it can also be considered that the higher figure would apply to the longer of the two routes. Installation of submarine cables across the Cook Inlet (Beluga Route) is not recommended due to bottom conditions, strong tidal currents, ice flows and resultant scouring. Pipeline installations in this area require continuous maintenance due to damage incurred by these conditions. The cost of installation of the land cables will depend to a large extent on local labor costs, nature of soil, environmental conditions, obstructions, i.e. pipeline crossings, rocks, etc, depth of burial and regulatory requirements. With limited February 16, 1987 ~ - Page Four information presently available we estimate a cost in the range of $500,000 to $600,000 per mile for normal installation conditions. Pressurization Equipment The cost of two dual remote controlled pumping plants for the submarine cables, one located at each end of the crossing, is estimated at $750,000. These plants are free standing requiring only a suitable foundation and a source of power. For the underground sections in the overhead lines, pressurization could be provided by means of oil pressure reservoirs mounted on supporting structure. Assuming two reservoirs per phase at each end and hence a total of twelve reservoirs, the cost of the reservoirs would be in the order of $40,000. Enclosed is a drawing of a typical termination with oil pressure reservoirs mounted on the supporting structure. Terminal Equipment The budgetary cost of each 138 kV termination (three required per 3 circuit at each end for land cable and four for submarine cable installation) is $10,000. The budgetary cost of each 230 kv termination (three required per 30 circuit at each end for land cable and four for submarine cable installation) is $12,250. Enclosed are drawings of typical terminations for 138 kV and 230 kV cables. Kindly advise if we may be of further assistance in this project.

One point needs further clarification concerning the new alignment. Right-of-Way will be acquired for a four-lane highway, however, only a two-lane roadway will be initially constructed tentatively in 1991-1992. This route will later be widened to four lanes to accommodate increasing traffic when warranted and dependent on the availability of funding in the future. Hopefully, this additional information concerning the Bird Point-Girdwood project will be useful to you in further evaluating route alternatives for the Anchorage-Kenai intertie. Please contact me at 266-1675 or John Dickenson of the DOT&PF Reconnaissance Section at 266-1500 if you have any questions. Sincerely, Weds M.

Since detailed maps of the Existing Route Alternative were not available during the meeting, comments on this route segment comments were deferred pending receipt of a copy of the maps from your office. Thank you for sending the annotated USGS quad maps showing the Existing Route Alternative alignment. The following are DOT&PF's plans for the Bird Point-Girdwood highway project. The highway realignment project will relocate the roadway closer to Turnagain Arm, i.e., from above the railroad right-of-way to between the railroad and the existing transmission line along the shore of Turnagain Arm. The new roadway will be four lanes to meet increasing traffic demands and probably will require some realignment of the railroad because of the limited area between it and the existing transmission line. Our design staff hopes to work closely with both the Alaska Railroad and APA during the design phase of this project. Project construction is programmed for 1991-1992. During the meeting on February 17, the suggestion was made by Al Meiners of the Division of Parks that underground cable be used for this segment of the new intertie to protect aesthetic values along this scenic area of Turnagain Arm. Also, the suggestion was made that the existing highway right-of-way be used for the underground cable, since the highway will be relocated anyway. I have discussed these suggestions with our design staff, who feel that an underground cable along the current highway right-of-way may be a good solution to some highway-railroad-intertie clearance problems which would arise during design of the new highway segment. If the existing transmission line along the shoreline were removed, the highway probably could be designed Closer to the shoreline, and less displacement of the railroad and excavation would be required. If the 230 KV option of the Existing Route Alternative were selected and the existing transmission tower alignment were utilized, this would require an additional 25 feet of utilities ROW, thus increasing clearance problems along this route segment. We, therefore, strongly es that an underground cable utilizing the existing highway roadbed be considered. Linda Perry Dwight 0s Hart Crowser, Inc. I hope these comments will be of assistance in further evaluating the route alternatives for the Anchorage-Kenai Intertie. Please contact me at 266-1675 or John Dickenson of the DOT&PF Reconnaissance Section at 266-1500 if you have any questions. Sincerely, Mp h CG ‘hue M.

Having reviewed this material and discussed the proposal during the February 17 meeting at the Alaska Power Authority, we agree with the general conclusion reached so far. That is, we concur with the decision to delete the Beluga alternative from further consideration. As both the Enstar and Tesoro routes would necessitate marine crossings of Knik Arm and construction of sub-stations at or near tidewater, these options are initially less attractive to our agency than the existing route alternative. We do not, however, consider any of the three remaining routes to be unacceptable at this time. We welcome the opportunity to review any additional information that you may provide.

Gill Hart Crowser, Incorporated 2550 Denali Street, Suite 900 Anchorage, Alaska 99503 J Dear Mr. Gill: This is in response to your request for our comments concerning the feasibility study you are conducting for the Alaska Power Authority to construct a new transmission line between Anchorage and Soldotna, Alaska. An interagency meeting was held on December 15, 1986, to introduce the study and present three general alternatives which you plan to study in detail within the next few months. These alternatives include: 1) Following the existing transmission line which generally parallels the Seward and Sterling highways; 2) a route across Turnagain Arm and down the west side of the Kenai Mountains along an existing natural gas pipeline; and 3) across the mouth of Turnagain Arm and along the east shore of Cook Inlet following the alignment of an existing | petroleum pipeline. As you develop more specific plans for these or other alternatives, we request that you consider the following: | a. Department of the Army (DA) permits would be required to construct a transmission line across Turnagain Arm, either aerial or subaqueous. Particularly sensitive biological areas such as those utilized by waterfowl or extensive marshes and mudflats should be avoided. You should also address construction impacts such as dredging, spoil disposal, effects on navigation expected to result from powerline installation. | b. DA permits would also be required to place dredged or fill material into waters or wetlands along the transmission line route. It is our understanding that the land - based portion of the line would be pole | or tower supported. Generally pole or tower sites should be on uplands wherever practical. Where supports would be located in waters or wetlands, the type of foundation should be addressed as well as equipment access, construction techniques and construction impacts. Permanent fills i or those desruptive to wetland hydrology and sensitive or unique biological areas should be avoided. Stee ss he —_—=S=V—T es =—wW c. Generally speaking, we would expect impacts to the aquatic environment to be minimized by following the existing transmission line corridor along the Seward and Sterling highways. Thank you for this opportunity to comment at this early planning stage of your project. If you have any questions on these comments, please contact Mr. Steve Lund of my staff at telephone (907) 753-2724.

Please refer to our letter to you of January 6, 1987, for comments on the routes currently under study. We note that a fourth alternative is now being considered. This alternative would run northwest from Soldotna, cross Cook Inlet to the west foreland and follow an existing transmission line to Beluga. With this alternative, we would add that a submarine cable crossing of Cook Inlet would require a Department of the Army permit. Given existing vessel use of the inlet, additional consideration should be paid to effects of this alternative on navigation. If you have any questions, please contact Mr. Steven W.

Gill Project Manager Hart Crowser, Inc. 2550 Denali Street, Suite 900 Anchorage, Alaska 99503 Re: Anchorage-Kenai Transmission Line Intertie Feasibility Study Dear Mr. Gill: In response to your January 26, 1987, request to provide narratives for each of the four Anchorage-Kenai Transmission Line Intertie routes proposed, we submit the following comments and concerns in the preferred ranking: 1. 2. Forelands/Beluga Substation Route (Sheet 4). This route, as proposed, should provide the least impact to Kenai National Wildlife Refuge (NWR) wildlife resources, involving only those refuge lands near the Beaver Creek drainage. Upgrading the existing facilities within the 200-foot rights-of-way now supporting a single pole 69kV facility, a 115kV double pole structure, and a buried 8-inch gas pipeline would be preferable to new vegetative clearing parallel and adjacent to the present rights-of-way. This route does impact former refuge lands, which are now Kenai Native Association lands under the Section 22(g) covenant of the Alaska Native Claims Settlement Act (ANCSA), the Marathon Oil Road, and the Beaver Creek drainage. Use of equipment within the drainage may be limited to winter conditions to protect the lowland bog, creek banks, and fishery resources. Proper posting and vehicle barriers must be installed at refuge boundaries and at the Marathon Oil Road crossing to control unauthorized vehicle use. Vegetative clearing will be minimized and vegetative screening of and within the right-of-way would be appropriate. Tesoro Pipeline Route (Sheet 3). This route, as proposed, also provides reduced impacts to refuge lands and includes all the concerns of priority 1, above. In addition, it involves the extreme northern tip of the refuge at Point Possession. The Tesoro 10-inch products pipeline (50-foot right-of-way) crosses approximately 4,700 feet of refuge lands. This route, however, is within the designated Kenai Wilderness, therefore, Title XI of the Alaska National Interest Lands Conservation Act (ANILCA) will apply and require both Presidential —_— fa af | a ee en ee ee ee and Congressional approvals. Also, this immediate area has been selected by the Point Possession Native Group for conveyance under ANCSA. Negotiations are currently underway between the Group and FWS. A number of bald eagle nests exist along this coastal routing, as well as trumpeter swan nesting locations. Shown as private land on Sheet 3, these former refuge lands, now private lands of the Tyonek Native Corporation, were conveyed with the 22(g) ANCSA covenant, i.e., ". . . lands remain subject to the laws and regulations governing use and development of such Refuge.” Existing Route (Sheet 1). The upgrading and use of the existing rights-of-way and facilities within the Kenai NWR is the preferred option under this routing. Designated Wilderness abuts both the Sterling Highway and the existing powerline rights-of-way north, which supports both 69kV and 115kV structures. Construction within the undulating terrain outside the rights-of-way would be limited. New vegetative clearing would further scar the natural scene, especially the mature forest areas along the Jean Lake hillside. Any new clearing authorized would have to immediately parallel the existing rights-of-way. New right-of-way routes would not be permitted. Winter construction within wetland areas would be required should heavy surface equipment be utilized that could result in surface scarring. Cook Inlet Region, Inc., (CIRI) 14(h)(1) selected lands include those adjacent the Russian River. Up to 600 bald eagles have been documented using the Kenai River drainage during winter. Additional line crossings could directly impact the mortality rates of eagles using this State-wide important bald eagle wintering area. Eagle nests adjacent the river have been identified. Draft recommendations for a Kenai River Special Management Area (KRSMA) Bald Eagle Management Plan will include several relating to the construction of new powerline crossings and modifications of existing transmission line facilities. Sufficient vehicle barriers and posting to control unauthorized vehicle use at the west refuge boundary will be required to be maintained for the life of the facility. Enstar Pipeline Route (Sheet 2). This proposed routing would impact the Kenai NWR lands most significantly and is the least desirable of the four proposed routings. The Chickaloon Flats region is a very sensitive waterfowl area. The approved Kenai Comprehensive Conservation Plan (KCCP), as mandated by Congress under ANILCA, does not allow the construction or use of facilities outside the existing right-of-way. In addition, the KCCP does not permit the construction of above ground facilities in the Chickaloon Flats area because of potential mortality problems associated with the migration of thousands of migratory birds. An underground facility within the existing 50-foot right-of-way would also be required. This right-of-way supports two buried gas pipelines, a bridge, gate, posting, and block valves. The routing of this right-of-way would also require the construction and continued maintenance of several bridges crossiag fishery streams. The siltation of fish streams disrupted during vehicie crossings and stream bank breakdowns would necessitate bridge construction. The maintenance — — —_— — —_— —= a _ — i i == and upkeep of the right-of-way to refuge standards are the responsibility of the permittee for the life of the facility (Enstar is wholly responsible for their right-of-way maintenance as uses impact the existing bridges and maintenance road). Most of the existing right-of-way passes through mature mixed forests. Bald eagle nests, fishery resources, and trumpeter swan nesting sites will be impacted along this proposed routing. In addition, stipulations attached and made a valid part of any special use permit authorizing this construction will include: o Selective vegetative clearing only. o Dozer clearing will be not authorized or will be very restricted. o Construction of gates and maintenance of posting for the life of the facility. o Access will be by the established and existing trails only. o No structures will be authorized within 150+ feet of the East Fork of the Moose River. o Certain structure placements may be mandatory to protect wildlife resources. o Equipment crossings of fishery resource waters will be restricted. o Timber salvage and payment to FWS for merchantable will be required. o Burning will be restricted as to time and place. o The reclamation of disturbed lands and streambeds will be mandatory and may require contouring, seeding and fertilizing as may be necessary during several seasons. o A surety bond of at least $100,000 will be required. o Authorization to utilize existing rights-of-way will be required from current right-of-way holders. o A letter of non-objection from CIRI will be necessary, as well as from any private inholder within the refuge. 0. EWS will be reimbursed for costs incurred in preparing and issuing any "permits and for inspecting, monitoring, and enforcing compliance with those permits.

Gill Hart Crowser Project Manager Hart Crowser, Inc. 2550 Denali Street, Suite 900 Anchorage, AK 99503 Dear Mr. Gill: Re: Anchorage-Kenai Transmission Intertie Feasibility Study The Alaska Department of Fish and Game (ADF&G) has reviewed the Preliminary Report on the Anchorage-Kenai Transmission Line Intertie Feasibility Study. For a variety of reasons, the report identifies the Enstar Pipeline Route as the preferred alternative. In conducting our review, the department was unable to identify any serious deficiencies in the Preliminary Report's conclusions. However, from a fish and wildlife perspective, we continue to believe that the Tesoro route would be preferable over the other alternatives evaluated if project impacts and mitigation costs are to be minimized. Given that specific project construction and design details are not available at this time it is unknown how much additional cost might be incurred in mitigating the Enstar Route compared to the Tesoro Route. However, while the amount probably would not approach the 20 million dollar cost differential that is estimated to exist between the two alternatives, the additional expense still could be substantial. This is based on the premise that there are more environmental concerns associated with the Enstar Route than the Tesoro Route that will require mitigation, and the fact that additional time and expense will be needed to gain approval to proceed in the Kenai National Wildlife Refuge. To the extent possible, we believe such factors should also be considered when evaluating these alternatives. In addition, the Preliminary Report does not address the department's suggestion that transmission towers associated with the Enstar Route might be sited east of Potter's Marsh State Game Refuge and the old Seward Highway. Such a James D. Gill -2- April 28, 1987 configuration would minimize the amount of wetlands that will be lost if the transmission line is buried in the railroad right-of-way, and would avoid a crossing of Rabbit Creek. This concludes the department's comments. If you have any questions, please do not hesitate to call. Sincerely N Wh & Mark N. Kuwada Habitat Biologist Habitat Division (907) 267-2284 cc: H.

MAY 08 1987 Hart Crowser Project Manager HART - CROWSER, INC. 2550 Denali Street, Suite 900 ALASKA Anchorage, AK 99503 Dear Mr. Gill: We have reviewed the Anchorage-Kenai Transmission Line Intertie Feasibility Study, Preliminary Report and offer the following comments, which are in addition to the comments we provided you on February 17th. The Enstar route, as we understand its alignment, would enter the Anchorage area somewhere in the immediate vicinity of the Potter Section House Historical Site. If this route is eventually chosen, the Division of Parks and Outdoor Recreation will require that the transmission line and any ancillary structures be located and constructed so their visual impacts are eliminated. This would include burial of transmission lines and the undergrounding of pump stations and other support structures for the marine cable. A primary purpose of Chugach State Park is “to protect areas of unique and exceptional scenic value..." We suggest that the intertie be buried parallel to and outside of the Alaska Railroad corridor. In the event that the Enstar route encounters technical or permitting difficulties and the APA must reconsider other route alternatives, we would reiterate our earlier concerns with the existing route and Tesoro route alternatives. In the case of the existing route alternative, we would require that several miles of powerline be constructed underground. The Powerline Pass area and other stretches of the route are highly scenic and would be protected with very strict mitigation requirements. The Tesoro alternative would traverse Captain Cook State Recreation Area. We would require that the line be entirely buried as it passes through the recreation area, paralleling the existing gas line and perhaps using its right-of-way. Please refer to our earlier comments concerning park areas which have recieved federal Land and Water Conservation Fund (LWCF) monies and the mitigations measures which would be required if their uses were to be converted to powerline purposes.

We strongly support the Huffman Substation option, which would have the least impact on Anchorage roads. We recommend that the final report include a detailed analysis of the two alignment options in the Potter Marsh area as well as further analysis of the Huffman Substation versus the International Substation options. Thank you for the opportunity to review this preliminary report. We look forward to receiving a copy of the final report in May 1987. Sincerely, M, Wink OB M.

Gill Hart Crowser, Inc. 2550 Denali Street, Suite 900 Re: Anchorage/Kenai Intertie Anchorage, Alaska 99503 Kenai National Wildlife Refuge Dear Mr. Gill: In response to your letter request of February 27, 1987, with accompanying documents, we take this opportunity to provide the following comments regarding the proposed Anchorage/Kenai transmission line Intertie as it may impact Kenai National Wildlife Refuge (NWR) lands. The proposed Tesoro route between Bernice Lake and Point Possession provides for an alternate routing east of Stormy Lake outside any existing refuge right-of-way. Substantial evidence supporting this route with respect to its compatibility with the purposes for which this refuge was established and whether there is any economically feasible and prudent alternative to the routing of this proposed utility system through this conservation system unit will be required. In addition, we are uncertain as to the criteria used in your feasibility study document titled, Evaluation of Environmental Impacts Summary. We are therefore not necessarily in agreement with that summary. We appreciate this opportunity to comment on the provided material and request you kindly keep this office advised of any new developments involving Kenai NWR lands. Sincerely, Daniel W.

Gill " Hart Crowser Project Manager Hart Crowser, Inc. 2550 Denali Street, Suite 900 Anchorage, AK 99503 Dear Mr. Gill: Re: Anchorage-Kenai Transmission Intertie Feasibility Study The Alaska Department of Fish and Game has reviewed your letter of January 15, 1987 in which you present general information on four alternate routes for the Anchorage to Kenai transmission intertie. We are not providing detailed comments at this time because detailed engineering studies are not yet available. However; the following general comments are provided. 1s We strongly recommend that the Forelands/Beluga Substation route be deleted from further consideration because of the potential impacts to the Trading Bay State Game Refuge and several Major anadromous fish streams. 2. We are concerned about the potential adverse impacts associated with the Enstar Pipeline route on the Potter Point State Game Refuge, particularly the Potter Marsh portion. If the line were to be buried along the Seward Highway and the Alaska Railroad, important wetlands would be disturbed, and a crossing of Rabbit Creek would be required. The transmission line would also pass through the Rabbit Creek rifle range and could adversely effect its operation. An aerial line along the Old Seward Highway in back of Potter Marsh would be more acceptable, if it could ' be screened from the Marsh. Construction would have to be scheduled to avoid impacts to important wetlands and wildlife populations. 3. The Tesoro Pipeline route appears to be acceptable because impacts to the Potter Point State Game Refuge will be minimized. ft James D. Gill . February 9, lLyu?/ 4. Construction along the existing transmission line route will involve numerous anadromous fish streams, and department approval will be required for crossings. Timing of construction will have to be closely coordinated to avoid impacts to these streams. The department will provide more detailed comments as additional information becomes available.

Gill, P.E. Hart Crowser, Inc. 2550 Denali Street, Suite 900 Anchorage, AK 99503 Dear Mr. Gill: Thank you for the opportunity to comment on the Anchorage-Kenai Transmission Line Intertie Feasibility Study. Due to the short review time our comments are limited. As more economic and engineering studies become available, we will comment in greater depth. The existing route described in Section 3.1 may present the least land acquisition and permitting difficulties since the rights-of-way have already been acquired for electrical power transmission purposes. As with all four routes presented, land status may have changed since permitting of the existing right-of-way, which may present different permitting requirements. The existing route should also be re-evaluated to determine if the route is still appropriate with the changes in land management priorities for the land impacted by the route. The Enstar Pipeline Route described in Section 3.2, being the shortest route and having the least state land impacted, is attractive, although we have the following concerns. It is unclear from the Feasibility Study how much additional right-of-way will be required for engineering safety with the transmission line route following the Enstar pipeline right-of-way and Alaska Railroad. If the land ownership along the Enstar Pipeline has changed since the acquisition of the pipeline right-of-way, the current land owner would be subject to the pipeline right-of-way as it existed at the time of transfer. Therefore, changes to the use of the right-of-way may necessitiate negotiating with the new land owner. Other concerns with a route along the railroad are the instability of Potter Hill and an airport called "Tom's Landing" between the railroad and the Flying Crown Subdivision. James 0. Gill.

Hart Crowser Project Manager 2550 Denali Street, Suite 900 Anchorage, AK 99503 Dear Mr. Gill: We have reviewed your letter of January 29, 1987 which presented alternative routes for the proposed Anchorage to Kenal Transmission Line. We are unable to provide a detailed review of the alternatives without detailed maps and design specifications for the line. We are, however, able to offer some general comments and preferences concerning the alternatives. We strongly prefer either the West Foreland/Beluga Substation or Tesoro Products Line alternative. Our primary concern is to avoid placing the line through Chugach State Park or near the Potter Section House State Historic Site. As noted in the attached memo from Bill Garry, Superintendent of Chugach State Park, the line will have a major adverse visual and physical impact on Chugach State Park. Also, because of the investment of federal Land and Water Conservation Fund moneys in the park, detailed mitigation measures, including the acquisition of replacement lands, would be necessary. The existing transmission line in the park is considered a detriment to the park which was established "...to protect areas of unique and exceptional scenic value,..." The Enstar Gas Pipeline Route would be acceptable if the line is not located near the Potter Section House or is_ buried. The Tesoro Products Route will pass through the Captain Cook State Recreation Area. This recreation area has federal Land and Water and Fund invested in it = and, like Chugach State Park, will require mitigation and replacement of lands used for the powerline corridor. If state park lands are involved in the project, you will need to apply for a Special Park Use Permit. Comments on the routes for our field managers are attached for your review. Please feel free to contact us as you develop more information on the project. incerely, < Wy Al™Meiners Southcentral Regional Manager enclosures MEMORANDUM State of Alaska TO FROM Al einen’ Cranace: OATE January 28, 1987 SCRO FILE NO TELEPHONE NO 345-5014 Bill Garz--, ee 7 SUBJECT Anchorage to Soldotna Chugach/Southwest Son cee Powerline We. The proposals male a a: this area significantly are #1, the Existing Route, and #2, the Enstar Pipeline Route. I will immediately comment on #2 to refute the statement in the Feasibility Study that "It was considered desireable in the study to find a route east of Potter Marsh to connect to the Powerline Pass route of the existing pipeline." (pg 6.) Only as a last resort should a new line be built in Chugach State Park along “the highly scenic foothills and rim of the Anchorage Bowl. The park's legislation states clearly that "The park is established to...protect areas of unique and exceptional scenic value,..." The existing route was established before this legislation, and it would surely not be allowed if it were a new proposal at this time. In addition, if a new route were to be cut through the park, a large amount of recreation land would have to be added to the park to replace converted LWCF lands. Public sentiment, statutes, and cost availability of replacement lands would prohibit a route east of Potter Marsh through the park. The Existing Route (#1) has a permit for the existing powerline. According to verbal testimony from the Bureau of Land Management this permit is for the 115Kv line, and no further construction would be allowed without another permit. The BLM status plat shows two powerline rights-of-way, but in fact they are the same. Only one right-of-way permit has been issued (A04681l1) persuant to the Federal Power Commission License 2170 in 1964 (noted as Pwr Proj 2170 50' on the status plat). Any additional construction or use of a new right-of-way would require a new right-of-way permit from the Division of Parks and Outdoor Recreation, since most of the existing route in the park is on state TA'd or patented land. Comments on the Existing Route are as follows: l. The land has been dedicated by the legislature as State Park land and state statute requires protecting the land for its scenic value. New construction would run contrary to public sentiment and the Division of Parks and Outdoor Recreation policy to protect such resources. 2. New construction would require, under LWCF Agreement, the replacement of new right-of-way lands with land of equal value. Maintaining the integrity of park land and recreational values of Chugach State Park in this agreement would be at a high cost considering land replacement costs in this area. ALASKA STATE PARKS -- Let's Put Them on the Map! Al Meiners January 28, 1987 Pace 2 of 2 in cenclusion, I recommend that no new construction for the proposed cowerline be allowed in Chugach State Park. If, as a last resort, the oark must be used, the powerline, if feasible, should be comstructed underground and new land be purchased to replace right-of-way lands used.

Hart Crowser, Inc. 2550 Denali Street, Suite 900 Anchorage, Alaska 99503 Dear Mr. Gill: Due to the short review time frame, our comments will be cursory in nature. We hope to have a longer time to review and comment on a preferred alternative. The Seward/Sterling Highway Route probably has the least potential for impacting cultural resources. However, there are many known prehistoric and historic resources close to and in the existing right-of-way. If this becomes the preferred alternative, the route and the proposed upgrades will have to be inspected by an archaeologist to insure that any new pole or tower placement will not adversely affect a cultural resource. Some of the right-of-way has been surveyed by archaeologists, as a result of highway realignments. There may be only a limited account of field work necessary. All other proposed alignments may require more intensive pre-construction cultural resource surveys. There are known cultural resources sites in the vicinity of all alternatives and the probability is high that other such resources would be found as a result of archaeological survey. We look forward to working with you on this project. Please let us know the time of the meeting with APA scheduled for February 13, 1987. We may be able to send a representative. Sincerely, Neil C.

Gill, Project Manager HART - CROWSER, INC. Hart Crowser, Incorporated ALASKA 2550 Denali Street, Suite 900 Anchorage, Alaska 99506 Dear Mr. Gill, This is written with regard to your letter of April 13, 1987, concerning the “Preliminary Report for Alaska Power Authority Railbelt Utilities Anchorage-Kenai Transmission Intertie Feasibility Study," March 1987. The following comments, in addition to comments previously submitted in correspondence from this office dated January 6 and 26, -1987, are offered with regard to the above noted report and study: a. Construction of the Intertie would require issuance of a Corps of Engineers (Corps) permit prior to its installation. In the event that the Enstar Route remains the preferred alternative, preparation of an Environmental Impact Statement (EIS) concerning the use of wilderness areas within the Kenai National Wildlife Refuge is indicated. To assure that Corps concerns with regard to the proposed work are fully addressed in the EIS, this office anticipates serving as a cooperating agency with regard to its preparation. In the event that the Enstar route does not remain the preferred alternative, preparation of an EIS, from the Corps' perspective, may not be warranted. However, full discussion of alternative routes, including discussion of cable burying technologies, construction techniques, mitigation proposals, and other considerations would be required as part of permit application review. b. All areas subject to Federal jurisdiction, e.g., waters of the United States, including wetlands, and navigable waters of the United States (see 33 CFR 328 and 329 for a complete description of areas subject to Federal jurisdiction), (Enclosure), must be identified for each alternative route. Further, the environmental impacts of work performed in areas subject to Federal jurisdiction along each route require identification and discussion. c. Mitigation measures including avoidance, minimization, compensation, and enhancement must be addressed in future documentation associated with permit application and preparation of an EIS if required. Examples of mitigative measures would include burying the proposed cable within all or portions of alternative routes, providing screening for poles, scheduling construction activities during periods of minimal biological activity, and similar measures. d. With regard to alternative routes, this office suggests that a fifth alternative be considered. This alternative would extend from the Soldotna Substation, along the existing route, to Sixmile Creek drainage. From Sixmile Creek drainage, it would continue in the vicinity of Sixmile Creek until reaching Turnagain Arm. From the vicinity of the mouth of Sixmile Creek, a cable would be placed until connecting with the existing route on the northern side of Turnagain Arm. From this connection with the existing route, it would continue to its final destination in Anchorage. The advantages of this route include avoidance of wilderness areas within Kenai National Wildlife Refuge, avoidance of additional visual intrusions at the eastern end of Turnagain Arm, avoidance of certain avalanche areas along the existing route, and minimization of costs with regard to stepping down current to serve communities at the distal end of the Arm. Included within the discussion of the feasibility of this alternative would be discussion of acquisition of right-of-way lands, the feasibility of placing cable across Turnagain Arm at the vicinity of Sixmile Creek, permit approval requirements, and associated costs. e. Consideration should be given to burying the proposed cable within the Kenai National Wildlife Refuge. Though not eliminating all indications of intrusion, burying the cable would significantly diminish visual impacts within wilderness areas. The “Preliminary Report" indicates that the line would be buried approximately seven miles along the existing route and six miles along the Enstar Route. These proposed burials suggest that the technology is available for such an effort within the Refuge. f. The "Preliminary Report" discusses the proposed shape, height, and type of material of proposed poles; distance between poles; and other considerations. In addition to these design features, consideration should be given to other measures which would minimize visual impacts of the proposed line. Examples of such measures would include methods and locations of pole/line screening, pole/line orientation, and avoidance of promentories and other areas of particular scenic value. g. This office does not consider, at this time, the difference in cost among the alternatives presented within the "Preliminary Report" to be significant. The "Summary of Costs--Project Alternatives", Table 1.5-2 (Beluga Route excluded), indicates an increased cost between the least ~~ expensive alternative (Enstar Route, Huffman Substation Alternative), and the most expensive alternative (Tesoro Route, Point Woronzof Alternative), of $22,777,000, an increase over the least cost alternative of approximately 30%. The difference in cost between the Preferred Alternative and the Existing Route is $15,827,000, an increase over the least cost alternative of approximately 21%. The increased cost between the Existing Route and the second ranked alternative, Enstar Route (International Substation Alternative) is less, $13,424,000, or approximately 17% over the cost of the Enstar Route (International Substation Alternative). Though the above cost figures may be realistic in today's market, a delay of three years, the anticipated amount of time necessary to obtain necessary permits/approvals for the Preferred Alternative, could significantly alter costs depending on the then present interest rates, agency shifts regarding mitigation requirements, costs of materials and labor, and other considerations. Building a more expensive alternative earlier could be less expensive than building a lesser expensive alternative later. Further, delay of theBradley Lake project could further affect final expenditures of the proposed work. h. In Item "7.2.2," page 7-6, the term “regulatory floodplains" requires clarification. Reference to, and consideration of, Executive Order 11988 on Floodplains and of Federal floodplain studies is recommended. i. The discussion in Item "7.2.4," page 7-9, requires expansion. Areas subject to Federal jurisdiction, including wetlands, need to be identified for all alternative routes including the Existing Route. j. The comment in Item "7.2.5," page 7-12, “The potential for collisions would be moderate to high as the route along Cook Inlet intersects a major flyway," requires clarification and expansion. The terms “moderate” and “high” need to be quantified or put into context. The species at risk need to be identified. Measures to be taken to minimize collisions, including cable burial, need to be identified and eee This discussion should also include expansion of Item "7.2.6," page 7-13. k. Item "7.2.11," page 7-26, states that “Slash from right-of-way clearing that cannot be utilized and excavated materials that cannot be used as fill would be disposed of in approved sites." Activities involving deposition of dredged and/or fill material in waters of the United States, including wetlands, require Department of the Army authorization. In future documentation, site preparation, installation techniques, and maintenance of the Interite facilities require full explanation. The occasions of filling and of the measures to be taken to avoid or minimize filling in areas subject to Federal jurisdiction must be fully described. 1. With regard to coordination of the proposed work, this office requests that it be invited to attend all meetings with the U.S. Fish and Wildlife Service so that it may remain informed of current topics of discussion. Should you have any questions with regard to the above matters, please contact Mr. Jeffrey Steen at (907) 753-2724.

(CIRI) has reviewed the Anchorage-Kenai Transmission Line Intertie Feasibility Study. The upgrade of the existing 115KV line to a 230KV line will necessitate the revision of an easement across several CIRI parcels. Further, a number of previously unencumbered CIRI parcels will be impacted by the preferred Enstar Route. At this point, it is simply our intention to bring the need for easement revision and acquisition to your attention. With respect to the existing line, there are several CIRI parcels that contain an easement for a 115KV line. This easement (ADL 38269), which was transferred to CIRI's administration in 1982 by the State of Alaska, will need to be revised to reflect the proposed 230KV use and re-issued under a CIRI easement.

Intertie Anchorage, Alaska 99503 Kenai National Wildlife Refuge Dear Mr. Gill: We appreciate the opportunity to expand upon our necessarily hasty response to your initial request for comments regarding the four preliminary route selections for the proposed Anchorage-Kenai Transmission Intertie as they may impact Kenai National Wildlife Refuge (NWR) lands. After personal discussions with you and your representative Ms. Linda Perry Dwight, it appears only the two really viable routes, i.e., the Enstar and Tesoro alternatives, are still being discussed. In light of the limited time frame provided for our response, we will confine our discussion to these two routes. The Enstar Route recommended as the preferred alternative under the feasibility study, is certainly the more environmentally damaging to Kenai NWR lands. It is also in direct conflict with the Congressionally mandated Kenai Comprehensive Conservation Plan (CCP) as approved June 1985. That management direction confines such use to the existing Enstar right-of-way with buried facilities within the minimal management area portion. That direction also recommends new utility systems be routed away from the Chickaloon Flats/Alaska Pipeline Company corridor to the coastal strip of former refuge lands specifically provided for that use. The Enstar Route, as proposed, would require construction of a 125 foot wide right-of-way through 36 miles of forested refuge wildlands directly impacting 23 miles of a minimal management area now recommended for wilderness designation under the Wilderness Act. Construction of the powerline along this route will result in this area being unsuitable for wilderness designation. In addition to the certain visual and aesthetic impacts associafed with the Enstar Route, other negative effects include fishery stream siltation, additional bird strikes at stream crossings, with more than twice as many streams crossed via the Enstar Route, public pressure for access into otherwise undisturbed areas, other facility use demands, etc. Page 2 of 3, Anchorage-Kenai Intertie, Kenai NWR Although both the Enstar and Tesoro Routes are considered equally reliable, the original project costs as Listed iu the feaslbility study were only twenty-three percent more utilizing the Tesoro alternative, but this figure is qualified, because 22 miles instead of the earlier 4 mile distance must be buried along the Enstar route probably increasing that route's cost substantially. The Tesoro Route would also avoid any potential adverse effects on the wintering area of the lowland caribou herd, a major moose migration route, and the Chickaloon Flats waterfowl staging area. We are also unaware of any major waterfowl flyway the Tesoro route would cross. Except as a means of access, the Enstar Route does not utilize the existing right-of-way, rather it proposes to construct an entirely new right-of-way, an opportunity equally provided along the Tesoro Route alternative. Your letter dated April 29, 1987, which discussed the most current right-of-way location proposal for the Enstar Route, still requires the construction of a 125 foot maximum right-of-way clearing. This proposal impacts about 545 acres of refuge forest lands with new access routes to approximately 223 adjacent pole structures and the development of a completely new refuge right-of-way. The Tesoro Route, in contrast, would only require clearing about 12 acres within the Kenai NWR, should additional clearing be required outside the existing 200 foot transmission line rights-of-way. Current laws and regulations that govern non-program uses on National Wildlife Refuge lands require a compatibility determination. This transmission facility with its proposed Enstar routing will undoubtedly require an Environmental Impact Statement (EIS) under the National Environmental Policy Act (NEPA). One of the requirements under this Act necessitates a demonst ration that no other feasible alternative route(s) exists outside this conservation system unit. Also, under Title XI of the Alaska National Interest Lands Conservation Act (ANILCA) of 1980, a determination of whether there is any economically feasible and prudent alternative to the routing of the proposed system through or within this conservation unit that would result in fewer or less severe adverse impacts upon these wildlife refuge lands must be made. Your feasibility study supports such a route in the Tesoro alternative. In 1964, Congress approved a refuge boundary change which removed approximately 500 square miles from the refuge including all the coastal land from near Point Possession southwest to the Kasilof River to provide a future corridor for transportation and development. Again, during February 1974, the Kenai NWR was the subject of an extensive study by the Joint Federal-State Land Use Planning Commission. An analysis of refuge goals was evaluated to determine whether additions, deletions, or modifications of the existing refuge boundaries should be recommended. The Commission's summary of findings stated,~"Based upon the data available for this report, it appears that local communities have sufficient lands either within their control or yet to be conveyed by the State to the Borough to accommodate normal growth patterns for many years to come.” Page 3 of 3, Anchorage-Kenai Intertie, Kenai NWR More recently, Congress stated in ANILCA Section 10l(d), they had provided sufficient protection for the public lands and at the same time provided “adequate opportunity for satisfaction of the economic and social needs of the State of Alaska and its people.” Also, in 1982, the Alaska Department of Transportation and Public Facilities prepared the Kenai Regional Transportation Study (Phase II). This study found no additional needs for transportation corridors on the refuge but identified several needs nearby. Additional protection of refuge lands occurs under Section 4(f) of the Department of Transportation Act of 1966. This section states: “...the Secretary shall not approve any program or project which requires the use of any land from a...wildlife and waterfowl refuge...unless (1) there is no feasible and prudent alternative to the use of such land,...and is compatible with the purposes for which those lands have been established.” The laws and Congressional mandates governing management of refuge lands require a transportation or utility project be compatible with the primary purpose of the area [50 CFR 29.21-3(a)] if there is not any economically feasible and prudent alternative to the routing of the system off refuge lands. Support for the Tesoro Route alternative, both within the feasibility study and in those letter responses.from other agencies and corporations published within that document, is apparent. We continue to stand by our original response and for the reasons cited above and recommend the Tesoro Route alternative be utilized in support of the proposed Anchorage - Kenai Transmission Intertie facility.
