The field investigation was performed by a Dames &Moore senior engineer who sampled and classified the soils encountered in the boring and assessed the area.A relatively undisturbed sample of the near surface soils was obtained with a Shelby tube.The remaining samples recovered from the boring were disturbed bag samples obtained from the auger cuttings.The samples gathered are generally described on Table A-l. TABLE A-1 FIELD DESCRIPTION OF SAMPLES Sample Sample Depth Number Type (feet)Description 1 Shelby Tube 1.0 Orangish brown silty fine sand,loose 2 Bag 1.5 Grayish brown silty fine sand,loose 3 Bag 2.0 Dark gray silty fine sand,loose 4 Bag 2.5 Grayish brown silty fine sand,loose LABORATORY TESTING An undisturbed soil sample and three bulk samples were obtained from the test hole.The samples were packaged in moisture-proof containers and transported to the Dames &Moore Anchorage office for laboratory testing.In the laboratory,moisture measurements were performed on all samples with a den- sity measurement on the undisturbed sample.The results of the moisture and density tests are presented on Table A-2.Atterberg Limits,organic content, specific gravity,hydrometer and mechanical grain-size tests were performed on MLF6/C60 A-1 selected samples for classification purposes.Atterberg limits,organic content and specific gravity tests results are presented on Table A-2.Mechanical grain-size and hydrometer test results are presented on grain-size distribution graphs (Plates A-1 through A-4). Unconsolidated-undrained (TX-UU)triaxial compression,direct shear and lab vane tests were performed on the undisturbed sample to determine shear strength characteristics.The TX-UU test was performed with a constant rate of deflec- tion of 0.96 inch/minute with the direct shear test performed at a constant rate of deflection of .02 inch/minute.Additional details of the triaxial com- pression and direct shear test equipment are presented in Plates A-5 and A-6. Triaxial compression,direct shear and lab vane test results are summarized in Figure l.

UNCONFINED COMPRESSION AND TRIAXIAL COMPRESSION TESTS ARE PERFORMED ON UNDISTURBED OR REMOLDED SAMPLES OF SOIL APPROXIMATELY SIX INCHES IN LENGTH AND TWO AND ONE-HALF INCHES IN DIAMETER.THE TESTS ARE RUN EITHER STRAIN-CONTROLLED OR STRESS- CONTROLLED.IN A STRAIN-CONTROLLED TEST THESAMPLEISSUBJECTEDTOACONSTANTRATEOFDEFLEC- TION AND THE RESULTING STRESSES ARE RECORDED.IN A STRESS-CONTROLLED TEST THE SAMPLE IS SUBJECTED TO EQUAL INCREMENTS OF LOAD WITH EACH INCREMENT BEING MAINTAINED UNTIL AN EQUILIBRIUM CONDITION WITH RESPECT TO STRAIN IS ACHIEVED. TRIAXIAL COMPRESSION TEST UNITYIELD,PEAK,OR ULTIMATE STRESSES ARE DETERMINED FROM THE STRESS-STRAIN PLOT FOR EACH SAMPLE AND THE PRINCIPAL STRESSES ARE EVALUATED.THE PRINCIPAL STRESSES ARE PLOTTED ON A MOHR'S CIRCLE DIAGRAM TO DETERMINE THE SHEARING STRENGTH OF THE SOIL TYPE BEING TESTED. UNCONFINED COMPRESSION [TESTS CAN BE PERFORMED ONLY ON SAMPLES SETH SUPPFICHENT COHE> SION SO THAT THE SOIL WILL STAND AS AN UNSUPPORTED CYLINDER.THESE TESTS MAY BE RUN AT NATURAL MOISTURE CONTENT OR ON ARTUIFICIALLY SATURATED SOLLS, IN A TRIAXIAL COMPRESSION TEST THE SAMPLE IS ENCASED IN A RUBBER MEMBRANE,PLACED IN A TEST CIULAMRER.AND SUREROCTED Tor A CONFEXING PRESSURE TH ROI 'G HOUT THE pu RATION OF THEPioosi,NOOK ME ve br:ere re :rs n .ep ob tohabt PakSPECIALTESTSITMAYBEVARIEDINRELATIONTOTiitMiASSUREDSENESSES.PRIANIAL COMPRES- SION TESTS MAY BE RUN ON SOILS AT FIELD MOISTURE CONTENT OR ON ARTIFICIALLY SATURATED SAMPLES.THE TESTS ARE PERFORMED IN ONE OF THE FOLLOWING WAYS: GNCONSOLIDATED-UNDRKAINED:THE CON EINING @hiasi itt.IS Misia ON THE SAMPLE AT THE START OF THE TEST.NO DRAINAGE IS PERMITTED AND THE STRESSES WHICH ARE MBASURED REPRESENT THE SUM OF THE INTERGRANULAR STRESSES AND PORE WATER PRESSURES.

DRAINED:THE INTERGRANULAR STRESSES IN A SAMPLE MAY BE MEASURED BY PER- FORMING A DRAINED,OR SLOW,TEST.IN THIS TEST THE SAMPLE IS FULLY SATURATED AND CONSOLIDATED PRIOR TO THE START OF THE TEST.DURING THE TEST,DRAINAGE IS PERMITTED AND THE TEST IS PERFORMED AT A SLOW ENOUGH RATE TO PREVENT THE BUILDUP OF PORE WATER PRESSURES,THE RESULTING STRESSES WHICH ARE MEAS- URED REPRESENT ONLY THE INTERGRANULAR STRESSES.THESE TESTS ARE USUALLY PERFORMED ON SAMPLES OF GENERALLY NON-COHESIVE SOILS,ALTHOUGH THE TEST PROCEDURE IS APPLICABLE TO COHESIVE SOILS IF A SUFFICIENTLY SLOW TEST RATE IS USED. AN ALTERNATE MEANS OF OBTAINING THE DATA RESULTING FROM THE DRAINED TEST IS TO PER- FORM AN UNDRAINED TEST IN WHICH SPECIAL EQUIPMENT IS USED TO MEASURE THE PORE WATER PRESSURES.THE DIFFERENCES BETWEEN THE TOTAL STRESSES AND THE PORE WATER PRESSURES MEASURED ARE THE INTERGRANULAR STRESSES. Dames &Moore "PLATE A-5. 417.)(Rev.12-71)METHOD OF PERFORMING DIRECT SHEAR AND FRICTION TESTS DIRECT SHEAR TESTS ARE PERFORMED TO DETERMINE THE SHEARING STRENGTHS OF SOILS.FRICTION TESTS ARE PERFORMED TO DETERMINE THE FRICTIONAL RE- SISTANCES BETWEEN SOILS AND VARIOUS OTHER MATE- RIALS SUCH AS WOOD,STEEL,OR CONCRETE.THE TESTS ARE PERFORMED IN THE LABORATORY TO SIMULATE ANTICIPATED FIELD CONDITIONS. EACH SAMPLE IS TESTED WITHIN THREE BRASS RINGS, TWO AND ONE-HALF INCHES IN DIAMETER AND ONE INCH DIRECT SHEAR APPARATUS WITHINLENGTH.UNDISTURBED SAMPLES OF IN-PLACE SOILS ELECTRONIC RECORDER (IN SEATTLE OFFICE)ARE TESTED IN RINGS TAKEN FROM THE SAMPLING DEVICE IN WHICH THE SAMPLES WERE OBTAINED.LOOSE SAMPLES OF SOILS TO BE USED IN CON- STRUCTING EARTH FILLS ARE COMPACTED IN RINGS TO PREDETERMINED CONDITIONS AND TESTED. DirEcT SHEAR TESTS A THREE-INCH LENGTH OF THE SAMPLE IS TESTED IN DIRECT DOUBLE SHEAR.A CONSTANT PRES- SURE,APPROPRIATE TO THE CONDITIONS OF THE PROBLEM FOR WHICH THE TEST IS BEING PER- FORMED,IS APPLIED NORMAL TO THE ENDS OF THE SAMPLE YHROUGH POROUS STONES.A SHEARING FAILURE OF THE SAMPLE IS CAUSED BY MOVING THE CENTER RING IN A DIRECTION PERPENDICULAR TO THE AXIS OF THE SAMPLE.TRANSVERSE MOVEMENT OF THE OUTER RINGS IS PREVENTED. THE SHEARING FAILURE MAY BE ACCOMPLISHED BY APPLYING TO THE CENTER RING EITHER A CONSTANT RATE OF LOAD,A CONSTANT RATE OF DEFLECTION,OR INCREMENTS OF LOAD OR DE- FLECTION.IN EACH CASE,THE SHEARING LOAD AND THE DEFLECTIONS IN BOTH THE AXIAL AND TRANSVERSE DIRECTIONS ARE RECORDED AND PLOTTED.THE SHEARING STRENGTH OF THE SOIL IS DETERMINED FROM THE RESULTING LOAD-DEFLECTION CURVES. FRICTION TESTS IN ORDER TO DETERMINE THE FRICTIONAL RESISTANCE BETWEEN SOIL AND THE SURFACES OF VARIOUS MATERIALS,THE CENTER RING OF SOIL IN THE DIRECT SHEAR TEST IS REPLACED BY A DISK OF THE MATERIAL TO BE TESTED.THE TEST IS THEN PERFORMED IN THE SAME MANNER AS THE DIRECT SHEAR TEST BY FORCING THE DISK OF MATERIAL FROM THE SOIL SURFACES.

All drilling equipment is transported to the lower Fox Canyon Plateau by truck.This assumes that a usable road does not exist from Broad Bay to the drilling area or to Sugarloaf. All drilling equipment must still be helicopter transported from lower Fox Canyon Plateau to the production well site. All drilling operations are self-supported and they occur before power plant construction begins.This means that camp, helicopter,and construction equipment are not shared with power plant construction personnel. The production wells will be located immediately adjacent to Well ST-1,the existing production well.The production wellswillencountertheidenticalgeothermalresourceasST-1. The injection wells will be drilled on lower Fox Canyon Plateau and a suitable injection zone will be found at 600 feet below the surface. All drilling equipment is rented or leased.(With the present drilling economy,it may be cost effective to purchase a drilling rig,but this alternative was not evaluated).

The geothermal project will not produce the combustion gases and pollutants generated when standard fuels (coal,oil or natural gas)are burned for the production of energy.However,noncondensable gases and some particulates present in the geothermal fluid or gas stream could be released as air emissions, 1.0 PROJECT DESCRIPTION 'The geothermal project will consist of the following major facilities: Geothermal well(s)and wellhead arrangements. Flash separator upstream of the turbine. Turbine Generator. Air cooled condenser. Reinjection wells. The geothermal stream will be piped from the well to the flash separator. The stream will consist of 90 percent liquid and 10 percent steam (SAI Engineers).The liquid will be sent to reinjection wells.The steam will be piped to the turbine generator for the production of electricity.After the generator,the steam will flow to air cooled condensers.The liquid condensate from the condensors will be handled through reinjection wells,and the noncondensable gases will be routed through mufflers and discharged through stacks to the atmosphere, 44.45/6-1 -l- The initial phase in the project will include the construction of two (2) 2.5 MW single flash cycle units producing a total of 5.0 MW electricity.The initial phase will require 1,100,000 lb/hr total flow from the geothermal wells (SAI Engineering). The next phase in the project would be to add two (2)1.0 MW binary cycle units which would utilize the liquid from the single flash cycle units.The binary cycle units would raise the generation capacity of the project to 7.0 MW electricity (SAI Engineering).The addition of the binary cycle units would Not require any additional flow from the geothermal wells. The final phase in the project would be the addition of one (1)2.5 MW single flash cycle unit (without a coupled binary cycle unit).This would require an additional 550,000 lb/hr flow from the geothermal wells,bringing the total flow requirements to 1,650,000 lb/hr total flow (SAI Engineering). The completed project would produce 9.5 MW electricity. 2.0 AIR POLLUTANT EMISSIONS Air emissions result from venting the noncondensable gases present in the stream leaving the air condenser.The "worst case"analysis contained in this report reflects the assumption that all of the potential noncondensable gases present in this stream will be released to the atmosphere.Current data are insufficient to determine the amount of these gases present in the liquid stream leaving the air condenser,or the amount that will be present in the brine from the flash separator. The primary noncondensable pollutant of concern is hydrogen sulfide The HjS concentration in the Makushin Geothermal Field is 1.73 ppm by weight in the total steam flow (Republic Geothermal,Phase III Final Report, April 1985).This report notes that the three (3)samples taken in August, 1984 are believed to be accurate.These data show an average of 1.73 ppm H2S. Higher and more variable HjS analyses for the July,1984 samples are discarded because of procedural error in the laboratory analysis. 44.45/6-2 -2- 2.1 H5S EMISSIONS CALCULATIONS The hydrogen sulfide emissions are calculated for 1,100,000 1b/hr total flow for the 5.0 MW and 7.0 MW systems and 1,650,000 1lbs/hr total flow for the 9.5 MW system. 5.0 MW and 7.0 MW Systems 1.73 lbs HS x 1,100,000 lbs flow =1.90 lbs HS 1,000,000 lbs flow hour hour 9.5 MW System 1.73 lbs Hos x 1,650,000 lbs flow =2.85 lbs HyS 1,000,000 lbs flow hour hour 2.2 HoS YEARLY EMISSIONS If it is assumed that there will be continual emissions throughout the year (either on an operational basis or bypass situations),then the yearly emissions are as follows: 5.0 MW and 7.0 MW Systems 1.90 lbs HoS x 8,760 hr x 1 ton *8.32 tons H,S hr yr 2,000 1b yr 9.5 MW System 2.85 lbs HoS x 8,760 hr x _1 ton =12.48 tons H»S hr yr 2,000 1b yr 2.3 PARTICULATE EMISSIONS Particulates present in geothermal steam may be released into the atmosphere from steam venting during geothermal well drilling or from venting during malfunctions or shutdowns. 44.45/6-3 -3- The current project design incorporates the reinjection of the brine. Extensive cooling towers or ponds are not anticipated.Therefore,the associated particulate emissions should be minimal compared to other geothermal projects where particulates are released as drift.Drift refers to cooling water droplets (containing dissolved and suspended solids)that are entrained in the exiting air flow.The composition of the circulating cooling water and the mass of water released determines the total amount of particulate emissions.Because these particulates are emitted as part of water droplets ranging in size from a few microns to several hundred microns in diameter,they tend to settle to the ground in the vicinity of the cooling tower or pond. 3.0 AIR QUALITY IMPACTS The air quality in the area is assumed to be good.However,because of the natural geothermal activity in the area,those air pollutants which will be released from the geothermal project may already be present in the ambient air in the surrounding area,albeit at lower concentrations than process emissions. 3.1 AIR QUALITY MODEL DESCRIPTION The USEPA-recommended Industrial Source Complex (ISC)model was utilized to estimate the potential hydrogen sulfide impacts associated with the Unalaska Geothermal Project.The ISC model was designed to simulate fugitive emission sources such as material handling activities in a variety of configurations (e.g.,point,area,volume sources).For the geothermal project,the site area subject to installation was characterized as a series of point sources. Predicted concentrations were calculated for downwind receptors in micrograms per cubic meter (ug/m3), 3.2 MODEL ASSUMPTIONS The following emission factors and project assumptions will be used for modeling purposes to determine the ambient air quality impacts from the HS emissions. 44.45/6-4 | -4- 1.There will be one muffler and one stack for each 2.5 MW single flash cycle unit (SAI Engineering). 2.There will be two (2)stacks for the 5.0 MW and 7.0 MW systems and three (3)stacks for the 9.5 MW system.The emissions per stack are as followings: 5.0 MW and 7.0 MW Systems 1.90 lbs Hos x 1 =0.95 lbs H9S hour 2 stacks hour -stack 9.5 MW System hour 3 stacks hour -stack 3.The stack discharge of gases and steam from each single flash cycle unit will have the following characteristics (SAI Engineering): 95 lb/hr gases 63 lb/hr air leakage 678 lb/hr steam Total 836 lb/hr discharge The 836 lb/hr discharge from each single flash cycle unit will have the following characteristics (SAI Engineering): Temperature 225°F Pressure 14.0 psia Volume 370 acfm discharge 4.The stacks are each assumed to be twenty (20)feet high with a diameterof 6 inches (SAI Engineering). 44.45/6-5 -5- 3.3 MODEL RESULTS The maximum predicted l-hour hydrogen sulfide (HS)concentration for the 5.0 MW and 7.0 MW systems was 238 ug/m3 (0.17 ppm).The maximum predicted l-hour hydrogen sulfide (HjS)concentration for the 9.5 MW system was 357 ug/m3 (0.25 ppm).Both maximum concentrations were estimated to occur 100 meters from the source. There are no state or federal ambient air quality standards for HS.The State of Alaska has a reduced sulfur compound standard,expressed as sulfur dioxide (S05)of 0.02 ppm as an odor threshold guideline for HS.The Threshold Limit Value (TLV),as recommended by the Association of Governmental Industrial Hygienists (AGIH)and the National Institute for Occupational Safety and Health (NIOSH),is 14 mg/m3 (10 ppm).This TLV is based upon cases which have indicated that H»S exposure at low concentations for a few hours has been associated with headaches,sleep disorders,nausea,and corneal injury.While estimated H)S impacts for the 5.0 MW,7.0 MW,and 9.5 MW systems exceeded the odor threshold guideline of 0.02 ppm,they are well below the TLV of 10 ppm. Modeling results indicate that the predicted concentrations drop below the odor threshold beyond 3.5 km from the source. 4.0 AIR QUALITY REGULATIONS The "worst case"emission calculations,assuming 100 percent gas libera- tion,no controls and continous emission throughout the year,showed 8.32 tons of HoS per year from the 5.0 MW and 7.0 MW systems and 12.48 tons of HoS per year from the 9.5 MW system.In addition,the facility is assumed to emit less than 250 tons per year of any criteria pollutant (NO,,S09,CO,hydrocarbons or particulates).Therefore,the facility would be exempt from Prevention of Significant Deterioration (PSD)review (18 AAC 50.300.6). However,the facility would require a permit from the Alaska Department of Environmental Conservation (ADEC)(18AAC50.300).Because the projected maximum H»S concentrations exceed the Alaska ambient air quality standard for reduced sulfur compounds,the ADEC could not issue this permit.Issuing a permit would 44.45/6-6 -6- require that the HoS emissions be reduced from the levels shown in Section 2.0. The actual emissions may be less than these levels depending on how much Hos remains in the liquid phase.Otherwise,additional emission control would be required. 5.0 CONTROL TECHNOLOGY If it is determined that some control of the hydrogen sulfide (Hos)is necessary,the following control technologies may be applicable to the Unalaska geothermal project. 5.1 IRON CATALYST PRIMARY SYSTEM The iron catalyst primary system removes H7§present in the condensate. This system uses iron to catalyze the chemical reaction of Hs to elemental sulfur.The elemental sulfur formed is removed by filtering the condensate stream after the reaction has occurred. The amount of H9S§in the noncondensable gases as a fraction of total incoming H9S in the steam is referenced to as partitioning.Since the overall H9S removal of the iron catalyst primary system is limited to the H2S in the condensate,the amount of HoS in the condensate is of critical concern.For maximum H9§removal with this systeni,minimum partitioning is desired. 5.2 IRON CATALYST SECONDARY SYSTEM The Iron Catalyst Secondary System is essentially identical to the Iron Catalyst Primary System in that iron is used to catalyze the reaction of HS to elemental sulfur.However,the secondary system is used in combination with other H9S control methods that remove H2S from the noncondensable stream.The Iron Catalyst Secondary System removes H9S remaining in the condensate after using another control system to maximize the removal of H9S present in the noncondensable gases. 44.45/6-7 -7- 5.3 HYDROGEN PEROXIDE-CAUSTIC-CATALYST (HPCC)SYSTEM Like the iron catalyst system,the HPCC system oxidizes HoS§contained in the condensate.However,unlike the iron catalyst system,hydrogen peroxide (H202)and caustic (sodium hydroxide,NaOH)are also added to the system in addition to the iron catalyst solution.The peroxide increases the oxygen available for Has oxidation which enables a high degree of abatement efficiency with high Ho9S loading.NaOH is sprayed into the after condensers to remove H2S from the noncondensable gases.The addition of NaOH also increases the pH of the condensate which in turn increases the amount of H9§absorbed into the condensate.A higher pH also favors formation of soluble sulfur compounds (sulfates)over elemental sulfur. This control system can be used as a primary or secondary removal system. The HPCC Primary System differs significantly from the HPCC secondary system. Used as a primary Hj$removal system,the HPCC system is designed to maximize the amount of HyS§in the condensate for subsequent liquid phase oxidation. Alternatively,where a gas phase primary H9S removal system is employed,such as the Stretford or burner/scrubber systems,the primary system is designed to maximize the amount of HS in the noncondensable stream.The relatively small portion of Ho9S remaining in the condensate is then oxidized by the secondary HPCC systen. 5.4 BURNER-SCRUBBER SYSTEM In a burner-scrubber system,the noncondensable stream is incinerated thereby oxidizing H9S to sulfur dioxide (S02).The SO?formed is then scrubbed from the flue gases by various conventional SO)control technologies. 5.5 STRETFORD SYSTEM The Stretford system is currently the most widely used method of H9s abatement on newer power plants in the Geysers,California geothermal area. The Stretford system is designed for use with surface condensers although use with direct contact condensers is possible.This system removes over 99 percent of Hy9S contained in surface condenser noncondensable stream. Recently designed surface condensers have achieved up to 95 percent partitioning of H 9S into the noncondensable stream.Thus,approximately 95 percent overall H2S removal efficiency can be achieved. 44.45/6-8 -8- The Stretford system involves scrubbing the condenser off-gases with Stretford solution in an absorber after passing through a Venturi scrubber, The HoS-Stretford solution flows from the absorber to an oxidizing tank where air is injected to regenerate the Stretford solution and separate the elemental sulfur that is formed.The sulfur is then removed by froth flotation. 44.45/6-9 -9- APPENDIX D ECONOMIC ANALYSIS DETAILS ¢HKEKEHHKHEHEEHKEEEKKEEEKEREERREREEEEERE ¢ELFIN INPUT DATA FILE:UNALASKA.DAT ¢COMMAND FILE: ¢DATE LAST UPDATED:1/15/87 ¢UPDATED BY:M.FELDMAN ¢:NOTE:THIS SIMULATICN IS IN KW,NOT MW ¢ ¢ ¢ THOUSANDS,NiVi MILLIONS,OF DOLLARS REEEEREEEREE RAGEYR O BASE CALIBRATION YEAR Oo 1987 bASTYR O 25 YEARS AFTER INTIAl GOETHERMAL PLANT ON LINE O 2016 PRWGEN O YEARS FOR CHOSEN RUNS 7 1988 1989 1990 19792 1995 2000 2005 2010 2015 ¢:KHHKEKKKKEKKKKKKEKKEKKKEKKEKKKKRKEKKKKEKEKEE c RESOURCE CATEGORIES :KKCKKHHKKKKEKHKKEKEEKRRRHEREEHERE CLI-CEN ©ELECTRIC GENERATION PLANT CATESORIES 7 "DSL1i''DSL2''DUI3'"'DSL4''DSLS''DSL6''DSLA' '"GEDI'"SGIP' D&E AXX O 1450 KW DIESEL UNIT DoLeXX O B55 KW DIESEL UNIT - DUE aXX O 620 KW DIESEL UNIT DSL 4aXX O 600 KW DIESEL UNIT DG GXX O BOO KW DIESEL UNIT DSL SXX O 300 KW DIESEL UNIT Ind AXX O ADDITIONAL DIESEL UNITS CELOAXX O FIRST GEOTHERMAL SGIPXX O SELF GENERATORS GI-NGUM 1 EXISTING UNALASKA DIFSEL 7 "DSLi'''DSL2''DSLS'"DSL4'''DSLS''DSL6' STNGUM 2&ADDITIONAL UNALAGKA DIESEL UNITS 7 "DSLA' GENSUM 3 PROPOSED APA GECITHERMAL 7 'GEO!'
