AEA13-006 Grant Application Page 6 of 20 7/3//2012 Renewable Energy Fund Round 6 �4� _ Grant Application ENERGYAUTHORrrY SECTION 4 — PROJECT DESCRIPTION AND TASKS • The level of information will vary according to phase(s) of the project you propose to undertake with grant funds. • If some work has already been completed on your project and you are requesting funding for an advanced phase, submit information sufficient to demonstrate that the preceding phases are satisfied and funding for an advanced phase is warranted. 4.1 Proposed Energy Resource Describe the potential extent/amount of the energy resource that is available. Discuss the pros and cons of your proposed energy resource vs. other alternatives that may be available for the market to be served by your project. For pre -construction applications, describe the resource to the extent known. For design and permitting or construction projects, please provide feasibility documents, design documents, and permitting documents (if applicable) as attachments to this application. The energy resource available is the heat from the water jackets of the power plant engines. The heat available from the power plant significantly exceeds that required by the water treatment plant/washeteria most of the year, as indicated by the attached 2012 Heat Recovery Feasibility Study. The only realistic alternative to utilizing the recovered heat is to continue to burn over 7,000 gallons of fuel oil to provide the heat required by the water treatment plant. The cost of fuel is almost five times the cost of the recovered heat. The feasibility study and are contained in the attached 2012 Heat Recovery Feasibility Study. 4.2 Existing Energy System 4.2.1 Basic configuration of Existing Energy System Briefly discuss the basic configuration of the existing energy system. Include information about the number, size, age, efficiency, and type of generation. A heat recovery utilization spreadsheet has been developed to estimate the recoverable heat based on monthly total electric power production, engine heat rates, building heating demand, washeteria loads, heating degree days, passive losses for power plant heat and piping, and arctic piping losses. The spreadsheet utilizes assumed time -of -day variations for electric power production and heat demand. Power generation data from fiscal year 2011 is used in the spreadsheet. The estimated heat rejection rate for the lead power plant genset, a John Deere 6090, is used to estimate available recovered heat. Heating degree-days for Tuntutuliak were utilized for this site. All arctic piping is assumed to be routed above grade. All interior power plant hydronic piping is assumed to be 4-inch pipe with 1 inch of foam rubber insulation. 4.2.2 Existing Energy Resources Used Briefly discuss your understanding of the existing energy resources. Include a brief discussion of any impact the project may have on existing energy infrastructure and resources. The existing water treatment plant/washeteria building is hydronically heated. An energy audit of the facility performed in 2011 estimated annual fuel consumption of 7,114 gallons/year. Very importantly, because the washeteria is used year-round for water heating and laundry, the fuel consumption level is nearly as high in the summer as the winter. The existing power plant was designed for heat recovery and has a brazed plate heat exchanger and electric boiler already installed. The electric boiler will be used to convert excess wind power AEA13-006 Grant Application Page 7 of 20 7/3//2012 Renewable Energy Fund Round 6 GOOD Grant Application MENU ENERGY AUTHORITY into heat used by the water treatment plant/washeteria. 4.2.3 Existing Energy Market Discuss existing energy use and its market. Discuss impacts your project may have on energy customers. Heating oil must be barged in during the summer months. The impact of this project will be to reduce the overall use of oil by approximately 6,000 gallons per year. While this reduction will not change the price of oil in Tuntutuliak, it will significantly reduce the community's consumption of oil, replacing that consumption with jacket heat from the diesel engines and, potentially, excess wind energy in the future. 4.3 Proposed System Include information necessary to describe the system you are intending to develop and address potential system design, land ownership, permits, and environmental issues. 4.3.1 System Design Provide the following information for the proposed renewable energy system: • A description of renewable energy technology specific to project location • Optimum installed capacity • Anticipated capacity factor • Anticipated annual generation • Anticipated barriers • Basic integration concept • Delivery methods The heat recovery system captures the jacket water heat generated by diesel engines that is typically rejected to the atmosphere by the radiators. The recovered heat is transferred via arctic piping to the end user. The objective is to reduce the consumption of expensive heating fuel by utilizing available recovered heat. Although heat recovery is an excellent method of reducing heating fuel costs, recovered heat is a supplementary heat source and it is imperative that the end -user facility heating systems are operational at all times. Hot engine coolant is piped through a plate heat exchanger located at the power plant. Heat is transferred from the engine coolant to the recovered heat loop without mixing the fluids. Controls are used to prevent subcooling of the generator engines and reducing electric power production efficiency. The recovered heat fluid is pumped through buried insulated pipe to the end -user facilities, and is typically tied into the end -user heating system using a plate heat exchanger. POWER PLANT TIE-IN No modifications to the power plant cooling system are included, except those required to connect the arctic piping to the power plant heat exchanger and replacement of the heat exchanger. All heat recovery piping inside the power plant will be insulated with a minimum of 1-inch foam insulation. All valves will be either bronze ball valves or lug style butterfly valves with seals compatible with 50/50 glycol/water mixtures at 200F. Air vents, thermometers, pressure gauges, AEA13-006 Grant Application Page 8 of 20 7/3//2012 Renewable Energy Fund Round 6 �® Grant Application GEMD ENERGY AUTHORITY drain valves, and pressure relief valves will also be provided. ARCTIC PIPING (Recovered Heat Loop) The proposed arctic piping consists of a 3-inch polypropylene and fiberglass composite carrier pipe (Aquatherm Climatherm phaser composite) insulated with 3.5 inches of polyurethane foam insulation and aluminum outer jacket. The piping will be supported on sleepers on the ground surface and run from the power plant within existing rights -of -way to the end -user washeteria. The recovered heat fluid will be a 50/50 propylene glycol/water solution to provide freeze protection to the piping. END -USER BUILDING TIE-IN The water treatment plant/washeteria building tie-in consists of a brazed plate heat exchanger with motorized bypass valve to prevent back feeding heat to power plant. A brazed plate heat exchanger located in the water treatment plant/washeteria mechanical room will be tied into the boiler return piping to preheat the boiler water prior to entering the boiler. If required, a heat injection pump will be used to avoid introducing excessive pressure drop in the building heating system. The maximum anticipated delivered recovered heat supply temperature is about 190F. When there is insufficient recovered heat to meet the building heating load, the building heating system (boiler or heater) will fire and add heat. Off -the -shelf controls will lock out the recovered heat system when there is insufficient recovered heat available. The existing dryers will be replaced with new dryers with additional heating capacity to improve dryer performance when using recovered heat. Typical indoor piping will be type L copper tube with solder joints. Isolation valves will be solder end bronze ball valves or flanged butterfly valves. All piping will be insulated with a minimum of 1-inch insulation with an all -service jacket. Flexibility will be provided where required for thermal expansion and differential movement. Air vents, thermometers, pressure gauges, drain valves, and pressure relief valves will also be provided. The water treatment plant/washeteria will also receive a BTU meter to provide recovered heat use totalization and instantaneous use. 4.3.2 Land Ownership Identify potential land ownership issues, including whether site owners have agreed to the project or how you intend to approach land ownership and access issues. Land ownership is not an issue for this project. However, should heat recovery pipelines need to be routed through alternate routes, full easements or rights -of -way will be obtained. 4.3.3 Permits Provide the following information as it may relate to permitting and how you intend to address outstanding permit issues. • List of applicable permits • Anticipated permitting timeline • Identify and discussion of potential barriers No permits are anticipated for this heat recovery project. 4.3.4 Environmental Address whether the following environmental and land use issues apply, and if so how they will be addressed: AEA13-006 Grant Application Page 9 of 20 7/3//2012 Renewable Energy Fund Round 6 Grant Application • Threatened or Endangered species • Habitat issues • Wetlands and other protected areas • Archaeological and historical resources • Land development constraints • Telecommunications interference • Aviation considerations • Visual, aesthetics impacts • Identify and discuss other potential barriers ® ENERGY AUTHORITY ANTHC will consider all potential environmental concerns associated with this project. ANTHC has extensive experience using the comprehensive Indian Health Service (IHS) environmental review procedures for conducting environmental analysis of all health and sanitation facilities projects in all stages of development, as outlined in the IHS Environmental Review Manual issued in January 2007. 4.4 Proposed New System Costs and Projected Revenues (Total Estimated Costs and Projected Revenues) The level of cost information provided will vary according to the phase of funding requested and any previous work the applicant may have done on the project. Applicants must reference the source of their cost data. For example: Applicants records or analysis, industry standards, consultant or manufacturer's estimates. 4.4.1 Project Development Cost Provide detailed project cost information based on your current knowledge and understanding of the project. Cost information should include the following: • Total anticipated project cost, and cost for this phase • Requested grant funding • Applicant matching funds — loans, capital contributions, in -kind • Identification of other funding sources • Projected capital cost of proposed renewable energy system • Projected development cost of proposed renewable energy system The total anticipated project cost is $425,811, excluding ANTHC's in -kind contribution. A detailed construction cost estimate is contained in the attached 2012 Heat Recovery Feasibility Study. The requested grant funding is $425,811. The remaining $12,774 is being donated by ANTHC in the form of project and program management services. 4.4.2 Project Operating and Maintenance Costs Include anticipated O&M costs for new facilities constructed and how these would be funded by the applicant. (Note: Operational costs are not eligible for grant funds however grantees are required to meet ongoing reporting requirements for the purpose of reporting impacts of projects on the communities they serve.) As with all heat recovery systems, the operating cost will be minimal. The controls are automated both at the power plant and at the water treatment plant/washeteria. The most expensive components in the heat recovery system are the heat exchangers, and they normally have a minimum of a 30-year life. Minor maintenance costs will occur periodically, but they will be limited to valves, pumps, and possibly some replacement glycol. Approximately $500 per year AEA13-006 Grant Application Page 10 of 20 7/3//2012 Renewable Energy Fund Round 6 �4019) Grant Application GENE) ENERGY AUTHORITY should be budgeted for maintenance. 4.4.3 Power Purchase/Sale The power purchase/sale information should include the following: • Identification of potential power buyer(s)/customer(s) • Potential power purchase/sales price - at a minimum indicate a price range • Proposed rate of return from grant -funded p oject A standard Heat Sales Agreement will be executed between the power company and the Native Village of Tuntutuliak. The agreement will define the terms and methods for heat sales. Typical heat sales agreements charge end users the equivalent of one third of the cost of the fuel displaced. This amount is much lower than the retail price of fuel in the village.

Include direct cost savings, and) how the people of Alaska will benefit from the project. The benefits information should include the following: • Potential annual fuel displacement (gallons and dollars) over the lifetime of the evaluated renewable energy project • Anticipated annual revenue (based on i.e. a Proposed Power Purchase Agreement price, RCA tariff, or cost based rate) • Potential additional annual incentives (i.e. tax credits) • Potential additional annual revenue streams (i.e. green tag sales or other renewable energy subsidies or programs that might be available) • Discuss the non -economic public benefits to Alaskans over the lifetime of the project The potential fuel displacement is 6,000 gallons of the 7,100 gallons of fuel used at the water treatment plant/washeteria last year. The cost of the fuel is $6.80 per gallon (summer 2012). The annual cost of fuel displaced for the water treatment plant therefore equals $44,365. Over the 30-year life of the heat recovery system, the savings will be $1,330,950 in today's dollars. There are no other known incentives or revenue streams that will result from this project. The benefits to the community of this project include a reduction in the amount of fuel required by the community, a much more efficient use of the recovered engine heat, and a direct benefit to each community member due to the lower cost to produce, store, and deliver water. SECTION 6— SUSTAINABILITY Discuss your plan for operating the completed project so that it will be sustainable. Include at a minimum: • Proposed business structure(s) and concepts that may be considered. • How you propose to finance the maintenance and operations for the life of the project • Identification of operational issues that could arise. • A description of operational costs including on -going support for any back-up or existing systems that may be require to continue operation • Commitment to reporting the savings and benefits This project increases the sustainability of the water treatment plant and washeteria by reducing its operating cost by $1,330,950 over the 20-year life of the project. The minimal maintenance and operating cost can be funded out of its revenue stream and out of its savings over the 30- year life of the project.

Senior Director Resumes Supplemental Documents TUNTUTULIAK, ALASKA HEAT RECOVERY STUDY PREPARED BY: Alaska Native Tribal Health Consortium Division of Environmental Health and Engineering 1901 Bragaw St, Ste 200, Anchorage AK 99508 Phone (907) 729-3600 / Fax (907) 729-4090 July 17, 2012 EXECUTIVE SUMMARY The Tuntutuliak power plant and water treatment plant / washeteria (WTP/W) building were evaluated for heat recovery potential. The total estimated annual heating fuel used by the WTP/W is approximately 7,100 gallons. The estimated fuel savings realized by implementing a heat recovery system is approximately 6,000 gallons. The estimated cost for the heat recovery project is $401,000. The simple payback based on a 2011 fuel cost of $6.80/gallon is 9 years. Assuming construction in 2014, the design and construction cost with 2 years of 3% escalation is $425,800. The Tuntutuliak power plant is currently being modified to incorporate wind power. An electric boiler is currently part of the generator plant. The impact of the wind power is unknown at this point, but it is expected to reduce the benefit of recovered heat from 6400 gallons to somewhere around 6000 gallons. This changes the anticipated payback from 8.1 years with no wind to 9.8 years with wind. 1.0 INTRODUCTION The Alaska Native Tribal Health Consortium (ANTHC) reviewed the feasibility of providing recovered heat from the power plant to the existing WTP / Washeteria (WTP/W) in Tuntutuliak. ANTHC also developed a budgetary project cost estimate based on Force Account Construction, including Engineering and Construction Administration. The existing WTP/W building is hydronically heated. An energy audit of the facility performed in 2011 estimated approximately 7,114 gallons/year of fuel consumption and importantly, much of this load is present in the summer as well as winter. New equipment will include a large brazed plate heat exchanger, a new circulator pump, and controls to prevent back feeding of heat to the generator facility. The existing power plant was designed for heat recovery and has a brazed plate heat exchanger and electric boiler already installed. At present, the Tuntutuliak power plant is being upgraded to incorporate wind power. Per conversations with the power plant operators and contractors currently adding wind power generation, the existing heat exchanger needs to be replaced because of fouling, but other than that no additional work is required to incorporate heat recovery. The electric boiler will be used to convert excess wind power into heat used by the WTP/W. Additional assumptions have been made in the development of this report, including, but not limited to, the proposed arctic piping route, building heating loads, and flow rates and pressure drops of the heat recovery system. It is anticipated that refinements in arctic pipe size and routing, pump and heat exchanger sizing, and other design elements will be required as the project progresses to final design. Available as -built information was obtained from Tuntutuliak power regarding the 2011 power plant electrical loads as submitted for PCE. End -user annual fuel use was obtained from engineering estimates. Site visits were made to the existing washeteria and power plant to confirm accuracy of information obtained. 2.0 OVERVIEW The purpose of this study is to provide an estimate of the heat that can be recovered from the power plant diesel engines and used to offset heating oil consumption at the nearby WTP/W. Useable recovered heat is quantified in gallons of heating fuel saved using a gross heating value of 134,000 BTU per gallon of #1 arctic diesel fuel and an overall boiler efficiency of 75% for a net heating value of 100,000 BTU per gallon. The WTP/W studied for heat recovery is located within a 600-foot radius of the Tuntutuliak power plant. This analysis evaluates the potential to provide recovered heat to the WTP/W. The estimated average annual heating fuel consumption is 7,100 gallons. 3.0 ESTIMATED RECOVERED HEAT UTILIZATION A heat recovery utilization spreadsheet has been developed to estimate the recoverable heat based on monthly total electric power production, engine heat rates, building heating demand, washeteria loads, heating degree days, passive losses for power plant heat and piping, and arctic piping losses. The spreadsheet utilizes assumed time -of -day variations for electric power production and heat demand. Power generation data from fiscal year 2011 is used in the spreadsheet. The estimated heat rejection rate for the lead power plant genset, a John Deere 6090, is used to estimate available recovered heat. Heating degree-days for Tuntutuliak were utilized for this site. All arctic piping is assumed to be routed above grade. All interior power plant hydronic piping is assumed to be 4-inch pipe with 1 inch of foam rubber insulation.. The spreadsheet uses monthly heating degree-days to distribute annual fuel consumption by month. The washeteria commercial heating loads are field verified as approximately 70% of maximum utilization for 8 hours a day, 5 days a week. The end -user hourly heat load is compared to the hourly available heat from the power plant, less power plant heating loads and parasitic piping losses, and the net delivered heat to the end -user is determined. Following is a summary of annual fuel use and estimated heat utilization in equivalent gallons of fuel for each building: Facility Estimated Annual Fuel Use without HR (Gallons) Washeteria Total 7100 7,100 Estimated Annual Fuel savings with wind power incorporated (Gallons) 6000 6000 Estimated Annual Fuel Savings without wind power (Gallons) 6400 6,400 4.0 HEAT RECOVERY SYSTEM DESCRIPTION AND OPERATION: The heat recovery system captures jacket water heat generated by diesel engines and excess wind power that is typically rejected to the atmosphere by the radiators. The recovered heat is transferred via above -grade arctic piping to the end user. The objective is to reduce the consumption of expensive heating fuel by utilizing available recovered heat. Although heat recovery is an excellent method of reducing heating fuel costs, recovered heat is a supplementary heat source and it is imperative that the end -user facility heating systems are operational at all times. Hot engine coolant is piped through a plate heat exchanger located at the power plant. Heat is transferred from the engine coolant to the recovered heat loop without mixing the fluids. Controls are used to prevent subcooling of the generator engines and reducing electric power production efficiency. The recovered heat fluid is pumped through buried insulated pipe to the end -user facilities, and is typically tied into the end -user heating system using a plate heat exchanger. 4.1 POWER PLANT TIE-IN No modifications to the power plant cooling system are included, except those required to connect the arctic piping to the power plant heat exchanger and replacement of the heat exchanger. All heat recovery piping inside the power plant will be insulated with a minimum of 1-in foam insulation. All valves will be either bronze ball valves or lug style butterfly valves with seals compatible with 50/50 glycol/water mixtures at 200F. Air vents, thermometers, pressure gauges, drain valves, and pressure relief valves will also be provided. 4.2 ARCTIC PIPING (Recovered Heat Loop) The proposed arctic piping consists of a 3 inch polypropylene and fiberglass composite carrier pipe (Aquatherm Climatherm phaser composite) insulated with 3.5" of polyurethane foam insulation, and aluminum outer jacket. The piping will be supported on sleepers on the ground surface and run from the power plant within existing rights -of -way to the end -user washeteria. The recovered heat fluid will be a 50/50 Propylene Glycol/Water solution to provide freeze protection to the piping. 4.3 END -USER BUILDING TIE-IN WTP/W building tie-in consists of a brazed plate heat exchanger with motorized bypass valve to prevent back feeding heat to power plant. A brazed plate heat exchanger located in the WTP/W mechanical room will be tied into the boiler return piping to preheat the boiler water prior to entering the boiler. If required, a heat injection pump will be used to avoid introducing excessive pressure drop in the building heating system. The maximum anticipated delivered recovered heat supply temperature is about 190F. When there is insufficient recovered heat to meet the building heating load, the building heating system (boiler or heater) will fire and add heat. Off the shelf controls will lock out the recovered heat system when there is insufficient recovered heat available. The existing dryers will be replaced with new dryers with additional heating capacity to improve dryer performance when using recovered heat. Typical indoor piping will be type L copper tube with solder joints. Isolation valves will be solder end bronze ball valves or flanged butterfly valves. All piping will be insulated with a minimum of 1-in insulation with an all -service jacket. Flexibility will be provided where required for thermal expansion and differential movement. Air vents, thermometers, pressure gauges, drain valves, and pressure relief valves will also be provided. The WTP/W will also receive a BTU meter to provide recovered heat use totalization and instantaneous use. 4.4 RIGHTS -OF -WAY ISSUES There are no apparent conflicts with rights -of -ways for the arctic piping between the power plant and the end -user building, as the route is entirely within existing road rights -of -ways and on city property. A Heat Sales/Right-of-Entry Agreement will be required between the power utility and the end user to define the parties' responsibilities, detail the cost of recovered heat, and authorize the connection to the power plant heat recovery equipment. 4.1 POTENTIAL RISKS AND UNKNOWNS Incorporation of wind turbines to reduce generator power consumption will most likely reduce the amount of recovered heat available. Per discussions with the power plant operator, the generators are expected to maintain a base load of 80 KW with a minimum of 15 KW provided to the power plant electric boiler to level out wind fluctuations. Asa worst case scenario, it is expected to reduce the available recovered heat to approximately 75% of heat production with no wind power. However, it is unlikely that the wind generation will be sufficiently constant to maintain a steady 80 KW load. If wind is available beyond the electric power needs, the expectation is that power will be distributed throughout the community and delivered to electric furnaces in the homes. The minimum recovered heat benefit is expected to be around 4800 gal / year offset fuel use. The actual recovered heat benefit will be higher; probably around 6000 gal /year offset fuel use. 5.0 PRELIMINARY EQUIPMENT SELECTIONS The following initial equipment selections are sized and selected based on preliminary data and will require minor modifications to reflect final design. 5.1 Heat Exchangers Based on initial selected flow rates, brazed plate heat exchangers appear to be adequate for all locations. Initial heat exchanger selections are as follows. HX-1: (Power Plant). 300 MBH capacity Primary: 70 GPM 190F EWT (50% ethylene glycol), 0.6 PSI max WPD Secondary: 35 GPM 185F LWT (50% propylene glycol) 0.23 PSI max WPD HX-2: (Washeteria). 300 MBH capacity. Primary: 35 GPM 185F EWT (50% propylene glycol), 1.0 PSI max WPD Secondary: 35 GPM 180F LWT (50% propylene glycol) 1.5 PSI max WPD 5.2 Arctic Piping The length of heat recovery loop piping between the power plant and most distant facility is approximately 1,400 ft, round trip. The arctic piping utilizes 3-in carrier pipe to minimize pressure drop and reduce pumping energy. The pipe itself consists of a 3-in composite carrier pipe with 4.5-in polyurethane foam insulation and an aluminum outer jacket. The specified product is durable and resistant to crushing or abrasion. 5.3 Circulating Pumps P-HR1A & 1 B: Heat recovery loop to end -user buildings Flow = 35 GPM, Head = 35 ft Initial Selection: Grundfos Magna 65-120 with integrated VFD and differential pressure controller, 35 GPM at 35 ft TDH, 90OW 5.4 Expansion Tank Total heat recovery loop volume is approximately 550 gallons. Pressure relief at the power plant heat exchanger will be 45 PSIG and the maximum normal operating pressure will be 40 PSIG. ET-1: System requirements: 80 gallon tank and 41 gallon acceptance Select: Extrol ST-210V, 86 gallon tank and 46 gallon acceptance 5.5 GLYCOL MAKEUP The existing glycol make-up system at the washeteria will be adapted to accommodate filling the system and adding additional glycol. 5.6 CONTROLS Heat recovery system will use an off the shelf differential temperature controller to actuate a 3-way valve and start/stop heat injection pump (if used). Control will provide load shedding, freeze protection, and prevent backfeeding of boiler heat into heat recovery system. In addition, A BTU meter will be provided at each facility using recovered, displaying instantaneous temperatures and heat transfer, as well as totalizing BTUs used. Differential Controller: Tekmar Model 155 differential temperature control Control Valve: CV-1 Washeteria_ 2" 3-way motorized control valve with 24v Actuator BTU Meter: BTU-1 Washeteria: KEP BTU meter with 2" magnetic flow meter and matching temperature elements. 6.0 CONCLUSIONS AND RECOMMENDATIONS Estimated construction costs were determined based on prior recent heat recovery project experience, and include materials, equipment, freight, labor, design, construction management, and startup and testing. All work at the power plant and WTP/W, along with design and construction management/administration for the complete project, is included in the Base Project cost. Incremental costs for arctic pipe, end -user building renovations, and overhead and freight are estimated individually for each of the other end -user buildings (refer to attached cost estimate). The estimated project cost for is $401,000. Estimated annual fuel savings are between 4800 gallons and 6400 gallons. Based on discussions with the utility, available recovered heat will offset approximately 6000 gallons of heating fuel. Using a 2011 fuel price of $6.80/gallon results in an estimated annual community savings of $40,800 for a simple payback of 9.8 years. Funding for design and construction isn't expected before fall 2013, with construction occurring summer of 2014. With 2 years of escalation at 3% per year, the estimated project cost in 2014 is $425,800. w x I D m 250 200 150 100 50 0 Tuntatuliak Recovered Heat Utilization January February March April May June July Aug Sept Oct Nov Dec MONTH Washeteria Commercial Load (MBH) Washeteria Building Heating Demand (MBH) Available Recovered Heat 400 300 Tuntatuliak Recovered Heat Utili; 6000 Gal Recovered Heat 1100 Gal Bc May June July Aug MONTH a 0 TUNTUTULIAK, ALASKA ANTHC RECOVERED HEAT STUDY SHEET LIST TABLE Sheet Number Sheet Title 1 COVER 2 COMMUNITY SITE PLAN 3 SITE PLAN 4 SYSTEM SCHEMATIC 5 ISLEEPER DETAIL Alaska Native TUNTUTULIAK, AK Tribal Health Consortium ANTHC RECOVERED HEAT STUDY Division of Environmental Health and Engineering DATE: 05-20-2012 LAYOUT: COVER 1901 Smgaw StrW, Suits 200 ANCHORAGE, ALASKA, 9930E M DRAWN BY: TH FILE NAME: WTL—G—STSITE (007) 72MBOO CHECKED BY: WF SHEET 1 OF 5 USER: MOELLERING FILE: P\T1INTUTIILIAK\wRJE$iG1\wFt-ENERGr_$TUDr1wE-O-MTE.D19O PLOT DATE: 6121/2012 1:39 PM 40 v C DSxvv S�10 _z / .r fll Q (a,� S r zow n p1 1 ��q=—=Z 1 m A)0) N rJ 0 p;.�•z� m a ° rT m W m0 r 2 M D x MQ f ;; a 75 �� >_>sr�.�� �_'•L { C- 2 o CY, fT1 ] y , � • � N D � Y"• � V •`� 0 Z ] r ] oC Z] t ] s aC m r N] m ] 7 ' m ~ m ~ s DX Ml O n o < j W rr I r - L 4 w 71 per' O % k 4 USER: THOELLERING FILE: P•\T1INTUTUUAK�WTL-OESfG1\WTL_ENERGY-STUDY\WTL-f.-STSI-TE.D%G PLOT DATE: 5/21/2012 1:39 PM T-TM24 M r om m W Z °E S e d m i 07 7 pT �mm"a°,�=Z pi d X Lp ro �• S0 < C m � � m � . 3 N O0X *N m C D M X �m _ > Z ..n v W p � 0�.`z m I m �c� •, Z v zoN� o rn D D m DO { � O Z --1 2 O 0+ + X No r = (/: N D m m \ Q < -4 \ •_ m r \ m m > O0 -4 v \ - h., -.... d' .r m \ I;� 1= UJLN: INU[LLUUNu rut: PLUI DAIL: blZI IZ 1:59 PN POWER PLANT WASHETERIA r-----------------,r-------------------TO END USER 1 II HYDRONIC I AS-1 P—HR1 II SYSTEM I ! fl 1 !
