Box 7002 Ancho rage, Alaska 99510 Atten tion: Captain Robert Mohn Gentl emen: Attac hed are rev1s1ons to our report "Review of Southcentral Alaska Hydro power Potential -Anchorage Area". As re quested in your letter dated 24 November 1978, the following addit ions or clarifications are made: • • He did not use the term "transmission areas 11 • ~Je did, however, refer to "transmission access 11 • This we rated as good, moderate, or severe, depending on the distance and type of terrain a road or transmission line would have to traverse between the project site and the market area. This rating has been incorporated into our "land use 11 evaluation and had been listed on the individual site sheets as an aid to arranging the list of sites within the ranking group. (New information on the national monuments has also been placed in the 11 land use 11 evaluations.) Mr. Paul Lowe with the Alaska Center for the Environment re- evaluated several of the proposed sites (see attached letters). The term "too big" was based on two things: whether the power potential exceeded the needs of the immediate areas, and the amount of given head at a site. In several instances, the head had been misinterpreted (as at Strandline Lake) or was incorrect (as at Deadman Creek). On the individual site sheets we have indicated the updated evaluations with an asterisk (*). This information, as well as that submitted by the Trustees for Alaska, has been incorporated into the "Reckoning of Evaluations 11 ; these agencies' input had been received too late to be fully incorporated into the prelim- inary report .

The following items need clarification or addition to the , reports: a. Clarify the term "transmission areas" and define the role it has in the evaluation. b. Some of the smaller projects, such as Strandline Lake, Caribou Creek, Deadman Creek, etc., have been termed "too big" by the ~laska Center for the Environment. Recheck your evaluation. c. Incorporate Fish and Wildlife Service input into the report. This information should be available in two weeks. d. Incorporate the additional evaluation work being accomplished by the Alaska Center for the Environment, based upon information being collected by Mr. Paul Lowe. NPAEN-CW Hr. Ronald J. Rieland Contract completion will be extended to 16 January 1979 to allm'l incorporation of above information. Sincerely, JAY K. SOPER Chief, Engineering Division 2 Alaska Center for the Environment 1069 W. Sixth Ave. Anchorage, AK, 99501 December 27, 1978 Ms. Nanette Horvilt CH2~1-Hill 310 K Street Anchorage, AK, 99501 Dear Ms. Harvil) In my October 25 letter to Corby Howell, I indicated that we would be doing a more detailed evaluation of the 61 hydroelectric sites proposed as possible alternatives to the Susitna Dam project. This eval- uation is enclosed, and is supplemental to the preliminary version we submitted two months ago. We have also reviewed CH2¥-Hill's summary of the preliminary eval- uations, and wish to make a few comments: 1.) We share the concerns expressed by Mr. Petrie of the Alaska Depart- ment of Natural Resources in his October 20 letter,·regarding the need for more data before really meaningful evaluations are possible. ~·lhile realizing that this is a "first cut" in this direction, we are particu- larly concerned that the proposals be examined in light of the intended markets for the electricity generated at each one, and specific routing of transmission lines. In some cases, the environmental impacts (on habi- tat, etc.) of the transiDission lines may far exceed those of the dams they would service~., Sheep Creek site,fr44). 2.) While we have not done an extensive analysis of your summary, there appear to be some inconsistencies. For instance: a.) there seems to be excessive weight given to the "CH2M-Hill using LUPC Information" evaluation in determining a site's final rating. In several cases, scores of 10 in this area effectively offset "un- acceptable" ratings for impacts on fish or wildlife habitat <!...:.!.·, sites I 8, 53, 54, 56, 58). This is of special concern in light of the fact that the Alaska Division of Lands was not able to participate in the evaluation, producing a situation where "all state lands were indicated as 'acceptable' ••• ~ Again, we realize the limitations you had to work under, but this approach could lend itself to unrealistic, if not inaccurate, evaluations of various sites. ADL's input seems to be essential to this process i b.) our understanding is that _ftite within the Morton d-2 withdrawals was put into your Group Rank 6. Teklanika (#52) falls in this cate- gory (Morton McKinley Park additions), but is rated at 4. 3.) We would have preferred to see our evaluations, and those submitted by Trustees for Alaska, used on a par with those from public agencies, rather than as a secondary prioritizing mechanism. While the public agen- cies may bring greater specific credentials to bear on this, our organi- 2. zations probably have a broader perspective. If our input is solicited, it should be used on an equal basis with others'. These comments are very definitely not directed at anyone personally, or intended as flat criticism. tole support this evaluation process, ap- preciate the opportunity to participate, and want to see it be as effec- tive and comprehensive as possible. We strongly feel that this evaluation process should produce a document as substantive in fact as in name. Again, thank you for your assistance, and for the opportunity to participate. We hope to be able to continue in this role.

Sixth Ave. Anchorage, AK, 99501 December 27, 1978 SUBJECT: Revised evaluations of 61 proposed hydroelectric sites NOTES: 1.) These are supplemental to our earlier evaluations, dated 10/25/78. 2.) At that time, the onl~ata available to us was site location and 11h" (head?) figure, for each one. (There are apparent errors in some "h" figures, such as /128-Deadman.) Our judgements as to size of the installations and/or lake involved were based on these data. These revised evaluations were done using CH2M-Hill's summary of the initial evaluations, 1:250,000 maps showing site location and lake areas, and additional references. As a result, our initial findings have been revised in some cases. 3.) We have not re-examined those sites in Rank Group 6 of CH2~Hill's summary, on the assumption that those will be ruled out by reason of other input. If this assumption is incorrect, we would appreciate noti- fication. 4.)

Sixth Avenue Anchorage, Alaska 99501 Dear Mr. Lowe: Attached is a copy of the rev1s1ons to the report "Review of Southcentral Alaska Hydropower Potential -Anchorage and Fairbanks Area 11 , which we submitted to the Corps of Engineers. l~e have carefully considered the points in your letter of 27 December 1978 and would like to make the following clarifications: 1 In view of the lack of better information, CH2M HILL chose to rate sites on state selected lands as good. We do not feel that this has adversely affected this stage of the site evaluations, since the current purpose is to eliminate the obviously poor sites. With fewer sites remaining to be considered, it will then be possible to do a more thorough study from all viewpoints, including that of land use. t The sites in D-2 withdrawals were not automatically placed in Group Rank 6. If a site was affected by D-2, CH2M HILL rated it as "unacceptable 11 in its land use evaluation. The fate of D-2 lands is too uncertain to automatically eliminate a site simply on that point. • We received the input from the Trustees of Alaska a~d the Alaska Center for the Environment too late to include it in the 11 Reckoning of Evaluations" in the preliminary report. However, these evaluations, as well as new data from other sources, have been included in the revisions. We hope this has answered any questions you have. Thank you for your cooperation in this effort. Sincerely, ' -~'t~~v·~ Nanette P. Harvill Enclosure hms Anchorage Office • 310 K Street, Suite 602 Anchorage, Alaska 99501 907 (279-6491
