Box 107044 Anchorage, AK 99510-7044 Re: Waste Heat Reports Dear Mr. Mjolsnes: To date we still have not received final copies of the waste heat studies for the communities of Anvik, Cold Bay, Hoonah, Kotlik, Lower Kalskag, Russian Mission, and White Mountain. It is important that the reports be completed as soon as possible to allow these sites to be included for consideration in the funding package that is currently being developed. In addition, it has come to our attention that we are currently holding invoices for the draft reports for the communities of Anvik, Kotlik, Lower Kalskag, Russian Mission, and White Mountain. Payment of the invoices was withheld because the amount billed did not correspond with the current level of completion of the reports. On the final invoices for these communities, please include a note indicating that the previous invoices are void and bill for the total amount due. Thank you for your prompt attention. If you have any questions feel free to contact me at 261-7294. Sincerely, ee Me Brian C.

We have since decided that this is not necessary. If the calculations have not been changed, disregard the previous comment. If they have been changed, the revised calculations will be acceptable. We have reviewed the Draft Report and Concept Level Design for the Hoonah Waste Heat Recovery project and have the following comments: 1. General Comment - We have not attempted to perform a thorough check for spelling and grammatical errors but it appears that there are several mistakes. The entire report should be carefully checked and edited prior to resubmittal. 2. Section 1.0 - Do not deduct annual O&M costs from fuel savings but rather show total annual fuel cost savings. 3 Section 4 - Provide a brief description of the location of new equipment within the power plant and connection to existing systems similar to those under Section 5. 4. Section 4 - On the power generation data, add units to the column headings for "PEAK LOAD" and "FUEL USE." 5. Section 5 General Comments - Revise report format as follows: A. Print the narrative for each facility on an individual page followed immediately by the photographs and heating fuel consumption data for that facility. B. At the end of each facility narrative add a sentence listing the annualized average fuel consumption for the building and whether this is based on delivery records or estimated from heat load calculations. i apabastieoes Store of Alaska aA Steve Cowpe: Governor Alaska Bnergy Authority A Public Corporation TELECOPY (ANCHORAGE Telecopy Phone No. (907) 561-8584) (JUNEAU Telecopy Phone No. (907) 465-3767) TELECOPY SENT TO: <therles Fil<r~— NAME OF COMPANY: Frew kk. rMheelin « Asscoa_ COMPANY ADDRESS: Aaron TELECOPY PHONE NUMBER: ZrIe~ ie Fo SENDER: Eerciaw rev TELEPHONE NUMBER: 26\ - 729 CHARGE CODE: #Biezo toe NUMBER OF PAGES SENT: Z INCLUDING THIS COVER PAGE DATE SENT: S/2z7/2vo IF YOU DO NOT RECEIVE ALL OF THIS TELECOPY PLEASE CALL: (907) 261-7240-Anchorage (967) 465-3575-Juneau Wacte TacaS+ Be port Feesiew) Comment.

Box 190869 704 East Tudor Road Anchorage, Alaska 99519-0869 (907) 561-7877 MEMORANDUM Date: 9/19/90 To: Charles Pilch Frank Moolin & Associates From: Brian C. Gray Rural Systems Engineer Alaska Energy Authority Subject: Cold Bay Waste Heat Recovery Draft Report We have reviewed the Draft Report and Concept Design for the above referenced project and have the following comments. While the list of comments may seem excessively long, the majority of items are minor grammatical errors. a5 Section 1.0 - Section 2.3 lists fuel costs as $1.10 per gallon, Total Annual Dollar Savings listed do not agree with this fuel price and the Total Fuel Oil Savings listed. Revise calculations. 2. Section 1.1.2 - Elaborate on whether staff reductions May actually result in closure of the FAA Shop facility. 3 Section 1.1.2 - In paragraph 3 add "warm storage" after "state shop". 4. Section 1.1.2 - In paragraph 4 add "heat" after waste in last sentence. 5. Section 1.1.3 - What are the desires of DOT/PF and FAA personnel and the power plant owner regarding the waste heat project? 6. Section 2.3 - What type of fuel is the cost listed for? A comment should be added here on what type of fuel is used for building heating and electrical power generation. 7. Section 3.0 - Were there any contacts made with DOT/PF personnel? If so list contacts. 8. Section 4.1 - In paragraph 1 correct spelling of "Caterpillar". 10. 11. 12. 13. 14. 15. 16. 17. Section 4.1 - Paragraph 2 lists 3 identical generator models with different outputs. Confirm this information or revise accordingly. Section 4.1 - In paragraph 4 the last sentence referring to heating load should be placed ahead of the sentence about structures to be torn down for clarity. Also, in the sentence about structures to be torn down "will be" should be changed to something like "are scheduled to be" since demolition is not part of this project and is therefore unsure. Section 4.1 - In paragraph 5 elaborate on the impact to available waste heat (i.e. will additional electric generation increase waste heat available or does Mark Air intend to buy waste heat). Section 4.4 - Add "(GAL)" below "FUEL USE" in Table 1. Section 5 General Comment - Revise report format as follows: a. Print the narrative for each facility on an individual page followed immediately by the photographs and heating fuel consumption data for that facility. b. At the end of each facility narrative add a sentence listing the annualized average fuel consumption for the building and whether this is based on fuel delivery records or estimated from heat load calculations. Section 5.1.1 - Clarify if steel paneled building is insulated. Section 5.1.3 - In third sentence change "It is" to "It will be" for consistency. Section 5.1.4 - Add length of piping run to first paragraph. Clarify if 391 MBH is for each boiler or combined capacity in second paragraph. Section 5.2 - Statement about present operating mode is unclear (how can return water and supply water both have operating setpoints). Review this section and clarify. Also make an estimate as to the quantity of fuel used for domestic water heating. We question the economic feasibility of providing a second heat exchanger. 18. 19. 20. 21. 22. 23. 24. 25. 26. 27. 28. 29. 30. Section 5.3.1 - Add "wood" prior to "frame structure" to maintain consistency. Also, was consideration given to adding the City Building to Scenario 1 with a short run of piping directly from the DOT warm storage building? Section 5.4.2 - Add "wood" prior to "frame structure" to maintain consistency. Also add "oil-fired" prior to "boiler". Section 5.4.3 - Is this the building referred to as “pump house" on the site plan? Coordinate names. Also add "feet" after "800". Section 5.5.1 - Would an additional boiler be required for the future building addition? Section 5.5.2 - In paragraph 1 add "wood" prior to "frame structure" to maintain consistency. Also add “each" after "2100 square feet". In paragraph 2 add "unit" or "building" after "Heating in each" in the first sentence. Section 5.6.1 - Add capacity of forced air furnaces. Section 5.6.2 - In paragraph 2 sentence 2 change "a H shaped" to "an H shaped". In sentence 3 change "oil fired hot air" to "oil fired forced-air" for consistency. In last sentence change "oil fired heating" to "oil fired water heaters". Section 5.6.2 - It seems inconsistent to provide fuel consumption data for this complex only and none of the others in this section. Revise accordingly. Section 5.6.2 - In the last paragraph change "buildings will require" to "buildings would require". Clarify which building (50x50 or 50x100) is the terminal and which building is the shop/hangar. Also correct spelling of "hangar". DOT/PF warm sand storage fuel consumption calculation - All heating demand calculations assume 75% efficiency while heat loss calculation uses 70%. Use 75% efficiency for all calculations. Section 6.0 - Has consideration been given to coordination of new waste heat piping with existing buried electrical lines? Would piping generally run alongside, over, or under electrical? Elaborate. Section 6.0 Paragraph 3 - Change "There is" to "There are". 31. 32. 33. 34. 35. 36. 37. 38. 39. 40. 41. 42. 43. 44, Section 7.1.2 - Change "will be there" to "should be there". Section 7.2 - In sentence 2 of paragraph 2 change "recovery" to "recover", Section 7.2 - The second paragraph does not make it clear that the intent is to utilize the existing heat exchanger for the new waste heat system in addition to the existing waste heat system. Revise accordingly. Also add a statement that by utilizing the existing heat exchanger, the operation of the existing power generators will essentially not be affected by the installation of the waste heat system. Section 7.3 paragraph 1 - Add a statement to the last sentence such as "and will enable the existing building heating systems to function normally in the event of a failure of the waste heat system". Is the owner of the power plant agreeable to having these changes made to the facility? Section 7.7 - Delete "the" prior to "Figure 26". Section 7.8 - Add guide specification for circulating pumps. Figure 1 - Correct spelling errors: "2-WAY CONTROL VALUE", "3-WAY CONTROL VALUE", "AMOT 3-WAY VALUE", and "AIR SEPERATOR". Figure 5 - Differentiate between new and existing piping in accordance with legend. Figure 6 - Will this arrangement affect required service clearances? Figure 14 - Differentiate between new and existing piping in accordance with legend. Figure 23 - Differentiate between new and existing piping in accordance with legend. Figure 26 - Revise to show bedding extending to 6" minimum above top of pipes and indicate 95% compaction of bedding. Section 9.0 - In paragraph 1 change "a least" to "at least". In paragraph 2 change "inexperience" to "inexperienced". In paragraph 4 change "introduce" to "introduced". 45. 46. 47. 48. 49. 50. 51. 52. Section 9.0 paragraph 4 - Is the reference here to ethylene or propylene glycol? This would be a good place to expound on the advantages/disadvantages of each. Section 9.1.1-5 - Change "on overload producing" to "on high temperature producing". Also the report should clearly state that this danger currently exists and that addition of the waste heat system will in no way affect this condition. Section 9.1.3 - Since loss of the waste heat does not constitute an emergency (existing building heating systems will still function) stockpiling pipe on site is not justifiable. A better recommendation would be for the Energy Authority to maintain an inventory of replacement arctic pipe in Anchorage to facilitate system repairs. Section 9.4.3 - Commercial glycol solutions always contain corrosion inhibitors. Clarify this point. Section 9.5 - State that this danger currently exists and that addition of the new waste heat system will in no way affect this condition. Section 9.8 paragraph 4 - Change "anyone" to "any one". Graph 1 - Large peak in heat available for January does not agree with heat generated data. Revise accordingly. Appendix 1 - Hourly heat demand variation on page 2 appears to be incorrect. Heat demand should decrease during the daytime due to higher outside air temperatures and increased internal heat gains. We have attached an example heat demand variation that you may wish to use. Revise calculations as required. Note that this comment applies to the calculations for all 4 scenarios.

Also, in the sentence about structures to be torn down "will be" should be changed to something like "are scheduled to be" since demolition is not part of this project and is therefore unsure. Section 4.1 - In paragraph 5 elaborate on the impact to available waste heat (i.e. will additional electric generation increase waste heat available or does Mark Air intend to buy waste heat). Section 4.4 - Add "(GAL)" below "FUEL USE" in Table 1. Section 5 General Comment - Revise report format as follows: a. Print the narrative for each facility on an individual page followed immediately by the photographs and heating fuel consumption data for that facility. b. At the end of each facility narrative add a sentence listing the annualized average fuel consumption for the building and whether this is based on fuel delivery records or estimated from heat load calculations. Section 5.1.1 - Clarify if steel paneled building is insulated. Section 5.1.3 - In third sentence change "It is" to "It will be" for consistency. Section 5.1.4 - Add length of piping run to first paragraph. Clarify if 391 MBH is for each boiler or combined capacity in second paragraph. Section 5.2 - Statement about present operating mode is unclear (how can return water and supply water both have operating setpoints). Review this section and clarify. Also make an estimate as to the quantity of fuel used for domestic water heating. We question the economic feasibility of providing a second heat exchanger. 18. 19. 20. 21. 22. 23. 24. 25. 26. 27. 28. 29. 30. Section 5.3.1 - Add "wood" prior to "frame structure" to maintain consistency. Also, was consideration given to adding the City Building to Scenario 1 with a short run of piping directly from the DOT warm storage building? Section 5.4.2 - Add "wood" prior to "frame structure" to maintain consistency. Also add "oil-fired" prior to "boiler". Section 5.4.3 - Is this the building referred to as “pump house" on the site plan? Coordinate names. Also add "feet" after "800". Section 5.5.1 - Would an additional boiler be required for the future building addition? Section 5.5.2 - In paragraph 1 add "wood" prior to “frame structure" to maintain consistency. Also add "each" after "2100 square feet". In paragraph 2 add "unit" or "building" after "Heating in each" in the first sentence. Section 5.6.1 - Add capacity of forced air furnaces. Section 5.6.2 - In paragraph 2 sentence 2 change "a H shaped" to "an H shaped". In sentence 3 change "oil fired hot air" to "oil fired forced-air" for consistency. In last sentence change "oil fired heating" to "oil fired water heaters". Section 5.6.2 - It seems inconsistent to provide fuel consumption data for this complex only and none of the others in this section. Revise accordingly. Section 5.6.2 - In the last paragraph change "buildings will require" to "buildings would require". Clarify which building (50x50 or 50x100) is the terminal and which building is the shop/hangar. Also correct spelling of "hangar". DOT/PF warm sand storage fuel consumption calculation - All heating demand calculations assume 75% efficiency while heat loss calculation uses 70%. Use 75% efficiency for all calculations. Section 6.0 - Has consideration been given to coordination of new waste heat piping with existing buried electrical lines? Would piping generally run alongside, over, or under electrical? Elaborate. Section 6.0 Paragraph 3 - Change "There is" to "There are". 31. 32. 33. 34. 35. 36. 37. 38. 39. 40. 41. 42. 43. 44. Section 7.1.2 - Change "will be there" to "should be there". Section 7.2 - In sentence 2 of paragraph 2 change "recovery" to "recover". Section 7.2 - The second paragraph does not make it clear that the intent is to utilize the existing heat exchanger for the new waste heat system in addition to the existing waste heat system. Revise accordingly. Also add a statement that by utilizing the existing heat exchanger, the operation of the existing power generators will essentially not be affected by the installation of the waste heat system. Section 7.3 paragraph 1 - Add a statement to the last sentence such as "and will enable the existing building heating systems to function normally in the event of a failure of the waste heat system". Is the owner of the power plant agreeable to having these changes made to the facility? Section 7.7 - Delete "the" prior to "Figure 26". Section 7.8 - Add guide specification for circulating pumps. Figure 1 - Correct spelling errors: "2-WAY CONTROL VALUE", "3-WAY CONTROL VALUE", "AMOT 3-WAY VALUE", and "AIR SEPERATOR". Figure 5 - Differentiate between new and existing piping in accordance with legend. Figure 6 - Will this arrangement affect required service clearances? Figure 14 - Differentiate between new and existing piping in accordance with legend. Figure 23 - Differentiate between new and existing piping in accordance with legend. Figure 26 - Revise to’ show bedding extending to 6" minimum above top of pipes and indicate 95% compaction of bedding. Section 9.0 - In paragraph 1 change "a least" to "at least". In paragraph 2 change "inexperience" to "inexperienced". In paragraph 4 change "introduce" to "introduced". 45. 46. 47. 48. 49. 50. 51. 52. Section 9.0 paragraph 4 - Is the reference here to ethylene or propylene glycol? This would be a good place to expound on the advantages/disadvantages of each. Section 9.1.1-5 - Change "on overload producing" to "on high temperature producing". Also the report should clearly state that this danger currently exists and that addition of the waste heat system will in no way affect this condition. Section 9.1.3 - Since loss of the waste heat does not constitute an emergency (existing building heating systems will still function) stockpiling pipe on site is not justifiable. A better recommendation would be for the Energy Authority to maintain an inventory of replacement arctic pipe in Anchorage to facilitate system repairs. Section 9.4.3 - Commercial glycol solutions always contain corrosion inhibitors. Clarify this point. Section 9.5 - State that this danger currently exists and that addition of the new waste heat system will in no way affect this condition. Section 9.8 paragraph 4 - Change "anyone" to "any one". Graph 1 - Large peak in heat available for January does not agree with heat generated data. Revise accordingly. Appendix 1 - Hourly heat demand variation on page 2 appears to be incorrect. Heat demand should decrease during the daytime due to higher outside air temperatures and increased internal heat gains. We have attached an example heat demand variation that you may wish to use. Revise calculations as required. Note that this comment applies to the calculations for all 4 scenarios.

Fay Mayor City of Cold Bay P.O.Box 10 Cold Bay, Alaska 99511 Subject: Waste Heat Concept Design Report Dear Mayor Fay: Please find enclosed a copy of the Waste Heat Concept Design Report prepared by the Alaska Energy Authority for your community. This report identifies potential waste heat end-users and provides an estimate of the amount of fuel that would be saved (in both gallons and dollars) for several different combinations of end-users. A cost estimate based on prevailing wage rates and contractor construction is also included for construction of the most feasible waste heat end-user combination. The designs presented herein are schematic in nature and should not be construed as being complete in design or function. A thorough review of content and correctness should be performed prior to use in the development of construction documents. The Energy Authority is currently in the process of reviewing the cost estimates and proposed waste heat end-user combinations to determine if a waste heat project would be economically feasible for your community. If additional information is required, a member of my staff will contact you. If you have any questions or need additional information, please call Brian Gray or Steve Stassel at 800-478-7877 or (907) 561-7877 or FAX (907) 561-8584.
