As your May 2 memo points out, indirect costs were not consistently applied through out that period, a fact that makes it difficult--even today--to determine what they should have been in 1989. It is my preference that staff not devote any additional time to identifying costs that might have been associated with these projects. In doing so, we would only add costs to the projects, while taking away time that we need to spend on current activities. In addition, we have already told the School District, in writing, what the project costs would be, and | do not wish to go back on that commitment. With this in mind, | would like to request that you close out the Togiak and New Stuyahok accounting files using the summary that you prepared in May 1990. Please issue a check for $5,514.61 to the Southwest Region School District and send it to Pat. We’ll prepare Notices of Project Completion to send along with the check and a cover letter reconfirming our understanding of the billing and refund. Thanks for your assistance. ce: Jack Templeton Pat Woodell April 4, 1991 qW Mr. Martin Myhre Business Manager Southwest Region Schools P.O. Box 90 \ Dillingham, AK. 99576 U\A RE: Togiak Waste Heat Project oo New Stuyahok Waste Heat Project Dear Martin: After our discussion about closing out these two projects last week, | reviewed accounting records with our staff. We came up with the cost summary on the attached page, which includes all of the costs specifically documented to these projects in the state accounting system (AKSAS). As | mentioned on the phone, there may have been additional costs, but we were not able to identify them because they were charged to general accounts rather than specifically to the two projects. During our telephone conversation, we attempted to reconstruct@q the School District/AEA purchasing relationship for the projects. You mentioned that you were certain that you had purchased waste heat pipe, but were unsure about heat exchangers, foam packs, and so forth. After reviewing project files, it seems clear to me that a majority of the materials purchases were invoiced directly to the School District. There is an April 1988 letter from Peter Hansen to you requesting that you order and ship waste heat pipe to the Energy Authority to replace AEA inventory that was used for the Tokiak, New Stuyahok and Clarks Point projects. It appears that waste heat pipe materials were received by the Energy Authority later that summer and that SWRSD was invoiced by Daningi. | can’t be certain from the records whether this was the original waste heat pipe purchase for the projects or this was the replacement purchase. | would appreciate knowing what your records show. As you can see from the attached summary, Energy Authority records document some contractor expenses that we incurred directly. The largest of these is for the Tranter heat. exchanger that was installed in Togiak. Please review this summary of charges and let me know if they concur with your recollection of how project billings were handled. Our records show that you advanced us $25,000 on June 22, 1987 and another $25,000 on June 15, 1988. After deducting all of our combined costs for both projects, we show a refund balance of $5,514.61. We are prepared to refund you this amount, unless your records show some differences on how the waste heat pipe replacement was handled. We certainly apologize for the delay in closing out these two projects. | am certain that the billings for Clarks Point and Manokotak will go more smoothly. For your information, Steven Stassel on our staff is the engineering contact for questions concerning waste heat projects.

Hansen State of Alaska Alaska Power Authority P.0. Box 190869 701 East Tudor Road Anchorage, Alaska 99519-0869 RE: Review Comments on Draft Design for New Stuyahok Waste Heat Project Dear Peter: It is requested that the following modifications be made to the piping schematic. 1. For Unit #1, pipe the heat exchanger in series with radiator #1 and use the existing valves to completely bypass all of the engine coolant flow around the existing AMOT valve. the coolant upon leaving engine #1 would flow first through the heat exchanger and then through radiator #1 and then return to the engine. Delete the proposed AMOT valve for Engine #2 and #3 and change the piping so that the heat exchanger and radiator are in a series path. The coolant upon leaving Engine #2 or #3 would flow first through the heat exchanger and then through radiator #2 and then return to the engine. Install a bypass line with valve so the heat exchanger can be completely bypassed in the event of a freeze up or core failure. Install a bypass line with valve between cooling system #1 and #2 so that under emergency conditions, Engine #1 could be cooled by radiator #2 or Engine #2 and #3 could be cooled by radiator #1. Size the piping to properly accommodate a future LTA 10 in Position #3 with a maximum cooling system restriction of 5 PSI at 90 gpm. Install] the Volkmann variable speed drive thermocouple sensor in the engine coolant outlet lines so they sense the temperature of the coolant leaving the engine. Mr. Peter Hansen August 2, 1988 Page 2 Ts cc: Install a small circulating pump for Engine #1 which will circulate flow through the heat exchanger and back to Engine #1 in order to keep it warm when either Engine #2 or #3 are on line.

Box 190869 701 East Tudor Road Anchorage, Alaska 99519-0869 RE: Review Comments on Draft Design for New Stuyahok Waste Heat Project Dear Peter: In our telephone conversation of August 10, 1988, you expressed concern that the heat rejection of the remote radiator core alone without the fan turning was appreciable and would severely reduce the amount of heat available for the heat exchanger. On this basis it was agreed that the AMOT Valve should be left in the circuit allowing the coolant to bypass the remote radiator if sufficient heat was removed by the heat exchanger. However, a 3/4" bypass is required around the AMOT to prevent thermal shocking of the radiator. It is requested that AVEC be provided with data showing the heat rejection capability of a Young 22D series radiator core without forced air flow under varying ambient air temperatures and typical coolant temperatures. It is also requested that the proposed Cummins LTA 10, planned for Position #3, be piped with a #4 Blue Aeroquip Hose from the engine vent outlet on the after cooler return tube to the top of the expansion tank as specified by Cummins. It is assumed that the APA will supply and install the necessary switches and wiring for the engine block circulating pump. Sincerely yours, Wak ¢ Ike? Mark E.

In accordance with our phone conversation, the AMOT valve is still incorporated in the design. 3. We agree, opening valve no. 2 and closing valves nos. 3, 4, and 11 will bypass the heat exchanger and the AMOT valve on one side of the system. On the other side of the system opening valve no. 21 and closing valves nos. 16, 17, and 19 will do the same thing. 4. We agree. Opening valves nos. 7 and 15 will interconnect the radiators to provide emergency cooling. When this mode of operation is utilized, the Volkman drives should be operated in the "Manual" mode. 5.
