Geotechnical Data Report Page ES-1 02/22/15 -yz.ALASKA ENERGY AUTHORITY SUSITNA-WATANA HYDRO AEA11-022 Clean,reliable energy for the next 100 years.1 6-1 434-REP-02221 5 1.INTRODUCTION 1.1.Project Description The Alaska Energy Authority (AEA)proposes to develop and construct a major hydroelectric facility,the Susitna-Watana Hydroelectric Project (Project),on the Susitna River near river mile 184.4 in the Talkeetna Mountains of south-central Alaska (Figure 1).AEA selected MWH Americas Inc.(MWH)to assist in the completion of engineering feasibility studies,including deriving the size and capacity of the major structures,developing the design to sufficient detail for verification of project development cost estimates,and defining the Project components and operation.MWH has subcontracted Golder Associates Inc.(Golder)to assist with geotechnical services related to the feasibility studies in support of the selection of a preferred dam type and optimization of the Project layout. The Project is currently in the pre-application phase of the Federal Energy Regulatory Commission (FERC)licensing process.This phase includes engineering feasibility studies,as well as environmental studies and planning,in support of a FERC license application. As currently envisioned,the Project would include an approximate 735-foot tall dam with a nameplate generating capacity of 600-megawatts.The proposed dam would likely consist of a curved gravity structure comprised of roller compacted concrete.The dam would impound a reservoir that is 42-miles long.Other key components of the Project include gated spillway, diversion structure,transmission lines to the existing grid,an access corridor to the site,and supporting facilities at the site such as switchyards,housing,roadways,and an airstrip. This Geotechnical Data Report (GDR)summarizes the data collected from field investigation efforts for the 2011 through 2014 field seasons related to geotechnical drilling,sampling,in-situ testing,instrumentation rehabilitation and monitoring,and laboratory testing. 1.2.Scope of Work The scope of work for the Susitna-Watana geotechnical investigations was developed in a phased approach beginning in 2011 and continuing through 2014.The field investigations were tailored each year to meet the project information needs,site access constraints,and project budgets. The overall objectives of the 2011 through 2014 field investigations were to define geologic conditions,determine rock mass properties,identify zones of alteration,weathering or shearing, investigate geologic structural features such as discontinuities,shears,lineaments and faults,and evaluate groundwater and ground temperature conditions at the dam site.These objectives were Geotechnical Data Report Page 1-1 02/22/15 -z ALASKA ENERGY AUTHORITY SUSITNA-WATANA HYDRO AEA11-022 Clean,reliable energy for the next 100 years.1 6-1 434-RE P-02221 5 achieved by conducting subsurface drilling,in-situ testing,and laboratory testing,as well as installing and monitoring geotechnical instrumentation. Exploration and testing program work plans were developed for each of the field investigation programs conducted in the 2011,2012,and 2014 field seasons (MWH,2011,2012;2013).The focus of the investigations was the proposed Quarry A identified by the U.S.Army Corps of Engineers (1979),the dam site foundation area and newly delineated Quarry M in 2012,and the dam site foundation area in 2014.|While the 2014 investigations are now complete,only a limited portion of the proposed exploration and testing program as outlined in the 2014-2015 Work Plan has been implemented (MWH,2013).Future field investigations and testing programs are planned to complete the work required to support feasibility. Permitting efforts were completed for the 2011,2012,and 2014 field season.Golder obtained water use and land access permits for the 2011 and 2012 field investigation efforts.The water use permits for the 2014 field efforts were obtained by MWH.For each of the field seasons, AEA obtained the necessary land access permits with support from MWH. Subsurface conditions were explored by advancing a total of 15 boreholes during the 2011,2012, and 2014 field investigations.The 2011 field investigations consisted of three boreholes in the proposed Quarry A location.The 2012 field investigations were comprised of five boreholes in or near the dam foundation,and three boreholes in proposed Quarry M location.The 2014 field investigations consisted of four boreholes conducted in the dam foundation area.In addition to the boreholes,bulk samples were collected from selected site locations for laboratory testing. Some rock cores from the 1970s and 1980s field programs currently stored at the Alaska Department of Natural Resources Geologic Materials Center (GMC)were reviewed in 2011 to determine which cores had been saved and to become familiar with the rock conditions at the dam site before beginning the field geotechnical investigation programs. Water pressure testing and down-hole televiewer surveys were conducted to evaluate in-situ conditions in the borings at the dam site.Water pressure testing was conducted at regular intervals in each of the 2011 through 2014 boreholes.Test data were used to determine the tightness of discontinuities,determine rock mass permeability,and too provide a qualitative evaluation of foundation grouting requirements.Down-hole televiewer surveys were conducted in selected 2012 boreholes and all 2014 boreholes.Data from the surveys were used to evaluate the rock discontinuities at depth,the geologic structure,in particular joint orientations,and zones of core loss. Laboratory testing programs were developed for each of the 2011,2012,and 2014 field investigations.In general,laboratory tests were used to evaluate the engineering properties of Geotechnical Data Report Page 1-2 02/22/15 -zZ.ALASKA ENERGY AUTHORITY SUSITNA-WATANA HYDRO AEA11-022 Clean,reliable energy for the next 100 years.1 6-1 434-REP-02221 5 the rock in the dam foundation and the suitability of rock materials from Quarries A and B as aggregate sources. Groundwater and ground temperature conditions were evaluated by reviewing existing geotechnical instrumentation in historical boreholes and installing additional geotechnical instrumentation in new boreholes.Historical geotechnical instruments were identified and evaluated as part of the 2011 field season.Selected instruments were retrofitted with new sensing equipment and/or fitted with data loggers to record data continuously.New geotechnical instrumentation consisting of stand pipe piezometers,vibrating wire piezometers,and temperature acquisition cables were installed in the 2011 through 2014 boreholes.Data loggers were installed to collect vibrating wire piezometer and temperature acquisition cables generated data over time.Instrumentation data and water levels from standpipe piezometers were collected at selected intervals during the 2012 and 2014 field seasons. 1.3.Project Datum Horizontal control for work conducted during the 2011 through 2014 field investigations was based on the North American Datum of 1983 (NAD83),Alaska State Plane (AKSP),Zone 4. Vertical control for the project was the North American Vertical Datum of 1988 (NAVD88).All horizontal and vertical coordinates have been expressed in feet unless otherwise specified. Coordinates and elevations provided for the 2011 through 2014 boreholes and structural data were not located by professional surveying methods.In most instances,locations were determined using recreational grade Global Positioning System (GPS)devices,which are strongly influenced by adjacent slopes and vegetation cover.Accordingly,coordinates and elevations provided should be considered approximate.

Geotechnical investigations and studies were conducted as part of this historical work at the Watana dam site.These studies included work that dated back to 1975 by the USACE,work by Acres American (Acres)in the early 1980s,and work by joint venture Harza-Ebasco in mid- 1980s.The bulk of the geotechnical work conducted during these historical studies is summarized in six geologic and geotechnical reports.These reports and a brief summary of the key geotechnical work that they contained are listed below: 1.USACE 1975.South-central Railbelt Area,Alaska,Upper Susitna River Basin, Interim Feasibility Report,Hydroelectric Power and Related Purposes.Alaska District,Anchorage,Alaska. A broad scoped feasibility report that includes a preliminary geologic and seismic evaluation of both the Watana and Devil Canyon Sites.This report presents an initial overview of the available geologic data available at the time,much of which was based on United States Geologic Survey (USGS)mapping efforts at the Devil Canyon Site (Csejtey 1974).The report also conducts a preliminary assessment of the regional seismicity. 2.USACE 1979.South-central Railbelt Area,Alaska,Upper Susitna River Basin, Supplemental Feasibility Report,Hydroelectric Power and Related Purposes.Alaska District,Anchorage,Alaska. The 1979 USACE report includes investigations and testing data conducted on both the Watana and Devil Canyon sites.Work conducted at the Watana site primarily focused on: =Geologic mapping of the dam and reservoir area; «Seismic refraction surveys at the dam site,borrow areas,and relict channel «Rock drilling and water pressure testing in the dam area; Geotechnical Data Report Page 2-1 02/22/15 -yz.-ALASKA ENERGY AUTHORITY SUSITNA-WATANA HYDRO AEA11-022 Clean,reliable energy for the next 100 years.1 6-1 434-REP-02221 5 #Soil boreholes in the Watana relict channel area; »Shallow auger holes in borrow areas; »Test pits of the borrow areas;and «Laboratory soil and rock testing. 3.Acres 1981.Susitna Hydroelectric Project:1980-81 Geotechnical Report. Similar to the 1979 USACE study,the Acres 1980-81 geotechnical report focused on both the Devil Canyon and Watana project sites.With respect to the Watana site,the 1980-81 investigation included the following key efforts: Geologic mapping at the dam site; Air photograph interpretation of the dam and reservoir areas; Rock drilling and water pressure testing in the dam area; Downhole geophysical surveys in selected borings; Installation of piezometers and thermistors in selected borings; Seismic refraction surveys of the dam site,Watana relict channel,and borrow areas; «Auger boreholes and test pits of borrow areas;and *Laboratory soil and rock testing. 4.Acres 1982.Susitna Hydroelectric Project:1982 Supplement to the 1980-81 Geotechnical Report. Acres'1982 report served as a continuation of the 1980-81 report,providing additional detail to the previous work.The primary tasks summarized in the 1982 report include: Geologic mapping of the dam site; Soil boreholes in the Borrow Area D and Watana relict channel area; Seismic refraction surveys of the dam site and relict channel areas; Installation of piezometers,thermal probes,and Laboratory soil testing. 5.Harza-Ebasco 1983.Susitna Hydroelectric Project:Watana Development Winter 1983 Geotechnical Exploration Program.September. This report investigated aspects of the Watana site primarily focusing on defining river alluvium depths and subsurface conditions at the dam and cofferdam locations.It also defined the subsurface conditions of the Watana relict channel in greater detail.Key portions of the 1983 investigation include: Geotechnical Data Report Page 2-2 02/22/15 -z-ALASKA ENERGY AUTHORITY SUSITNA-WATANA HYDRO AEA11-022 Clean,reliable energy for the next 100 years,1 6-1 434-REP-02221 5 «*Becker hammer borings within the Susitna River channel and Watana relict channel; "Geophysical surveys in the river channel,dam and cofferdam footprints, and Watana relict channel; «Water pressure and permeability testing; =Piezometer and thermistor installation; ="Downhole geophysical surveys,including gamma logging;and *Laboratory soil testing. 6.Harza-Ebasco 1984.Susitna Hydroelectric Project,FERC Project No.7114:1984 Geotechnical Exploration Program,Watana site.Document No.1735.July. The primary focus of this report was to identify the subsurface conditions in the major shear zones of the GF1 (Fins)and GF7 (Fingerbuster).In addition, boreholes were conducted in the area of the proposed underground powerhouse. Work associated with this investigation included the following key tasks: "Geologic mapping at the dam site and specifically the geologic features; =Rock drilling and water pressure testing in borings located in the GF1, GF7,and underground powerhouse areas; Hydraulic conductivity testing; Groundwater chemical analyses; Piezometer installations;and Laboratory soil and rock testing.

DH12-1,DH12-2,and DH12-8 were drilled on the left abutment to evaluate general rock foundation conditions.DH12-3 and DH12-4 were drilled on the dam site right abutment to evaluate historically mapped geologic features as well as general rock foundation conditions. DH12-5,DH12-6,and DH12-7 were drilled to evaluate Quarry M.These later three boreholes were conducted to explore both general rock conditions and a historically mapped geologic feature.All boreholes were drilled at angles ranging from 20 to 30 degrees from vertical and were typically oriented to penetrate the potential geologic features obliquely. Crux Subsurface Inc.(Crux)of Spokane Valley,Washington completed core drilling,water pressure testing,and installation of ground temperature and water level monitoring equipment for the 2012 investigation program.Rock coring was accomplished using a Burley 5500-3 drill rig and a Burly 6000 drill rig.Core was advanced using HQ3-triple tube wireline methods using a mixture of fresh water and EZ-Mud*polymer as a drilling fluid. 3.1.4.2014 Field Season Four rock core boreholes (DH14-9b through DH14-12),with a combined total footage of 1,850 lineal feet,were conducted during the 2014 field exploration effort.The 2014 field explorations were advanced to target specific postulated shears zones and mapped geologic features at the dam site. Boreholes DH14-9b and DH14-10 were advanced in a crossing pattern extending across the Susitna River from the north and south banks,respectively,to investigate the rock foundation conditions beneath the dam site area and to identify potential shear or fracture zones should they be present along the alignment of the river.Both boreholes were inclined at angles of 30 degrees from vertical.Borehole DH14-9b was drilled at an azimuth of 170 degrees from the lower right abutment.DH14-10 was drilled from approximately 300 feet downstream of the lower left abutment at an azimuth of 010 degrees. DH14-11 and DH14-12 targeted gullies on the right abutment that had been previously mapped as geologic features (Acres 1982a,1982b).DH14-11 was advanced at an inclination of 30 Geotechnical Data Report Page 3-2 02/22/15 -Z ALASKA ENERGY AUTHORITY SUSITNA-WATANA HYDRO AEA11-022 Clean,reliable energy for the next 100 years.1 6-1 434-REP-02221 5 degrees from vertical and at an azimuth of 035 degrees.DH14-12 was advanced at an angle of 30 degrees from vertical and an azimuth of 041 degrees. A fifth borehole,DH14-9a,was abandoned by the drilling contractor after excessive caving was encountered while attempting to advance casing through the overburden and into rock.A borehole,DH14-9b was completed at this location as described above. Crux also performed the drilling services in 2014,advanced the boreholes,conducted water pressure testing and installed geotechnical instrumentation for the 2014 field investigation effort. Drilling was conducted with a Burley 5500-3 drill rig and a Burley 6500 drill rig using HQ3 triple-tube wireline methods.Only fresh water was used for rock coring activities.Drilling fluids containing additives such as bentonite and polymers were allowed while advancing through overburden only. 3.1.5.Water Sources Fresh water for use in drilling and water pressure testing was obtained from area lakes in accordance with temporary water use permits.Water used for boreholes located south of the Susitna River (G11-DH01 through G1 1-DH03,DH12-1,DH12-2,DH12-5 through DH12-8,and DH14-10)was obtained from an unnamed lake located approximately 1.5 miles south of the dam site.Water used for boreholes located on the north side of the Susitna River (DH12-3,DH12-4, DH14-9b,DH14-11,and DH14-12)was pumped from "Panhandle”Lake,located approximately 1.5 miles north of the dam site.When water conditions were clean enough for drilling purposes during the 2014 field season,supplementary water was pumped from the Susitna River as needed for drilling circulation.Water pressure testing was not conducted with Susitna River water. 3.1.6.Core Logging and Classification Drilling operations and the recovered core samples were observed and logged by a geologist or geotechnical engineer.Rock samples were visually classified in the field according to International Society of Rock Mechanics (ISRM)standards for weathering,rock strength,core recovery,Rock Quality Designation (RQD),fracture index,and description of discontinuities (Brown 1981).Soil samples were visually classified in the field according to the Unified Soil Classification System (USCS).A field exploration manual was developed prior to the 2014 field season to provide guidance and to aid in uniform rock classifications.Rock core was photographed and boxed in the field for shipment back to Anchorage to be stored for further examination,classification,and testing.Geologic logs are presented in Appendix A,and core photographs are presented in Appendix B.

Water pressure tests were conducted using a five-stage test procedure in accordance with the recommendations presented by Houlsby (1976).During each pressure stage,water pressure and water take were recorded each minute for five minutes on an instrument console.For each water pressure test,water pressure was increased at regular intervals in three consecutive stages,and then reduced in the following two stages.Maximum allowable pressures were calculated based on in-situ stresses estimated for the midpoint of the test interval using assumed rock unit weights and groundwater elevations measured prior to the test.Actual test stage pressures were selected based on a maximum allowable pressure,rock condition,pump performance,and pressure range of the pressure gauge.Data including time,pressure,water take,and test interval length were used to calculate lugeon values for each test,which can be used to estimate permeability and the groutability of the rock formation. Water pressure tests were conducted using wireline-type packer assemblies that were lowered down through the drill string.With the exception of boreholes DH12-1 and D12-2,water pressure tests were conducted in a downstage (single packer)manner,with the bottom of hole acting as the lower point of test confinement.Upstage testing,using a double-packer assembly, was employed in DH12-1 and DH12-2. In general,boreholes were flushed with fresh water for approximately 10 minutes prior to water pressure testing.Polymers (used in the 2011 and 2012 field seasons)were not chemically broken down prior to testing.No polymers were used for rock core drilling during the 2014 field investigations.

Down-hole televiewer survey logs are presented in Appendix D. In the 2012 field season,down-hole televiewer surveys were conducted in boreholes DH12-3, DH12-4,DH12-6,and DH12-8.Optical televiewers were used to survey DH12-3 and DH12-4 since groundwater levels were relatively deep and water conditions were clear when encountered.Acoustic televiewer survey methods were selected for DH12-6 and DH12-8 since cloudy water conditions were present.Portions of the 2012 televiewer surveys were limited due to unstable borehole conditions.This was most notable in DH12-6 where caving conditions were encountered,limiting the down-hole televiewer survey to between the depths of 289.5 feet and 347 feet.Unstable borehole conditions also precluded televiewer surveys above a depth of 62 feet in DH12-3. Each of the four boreholes conducted during the 2014 field season were surveyed using down- hole televiewers.Since groundwater was encountered above the elevation of the bedrock in boreholes DH14-9b and DH14-10,these boreholes were surveyed over the entire length of the hole using both optical and acoustic televiewers.Optical televiewer surveys were conducted over the entire length of DH14-11 and DH14-12;however,acoustic televiewer surveys,which require water in the borehole to propagate the acoustic waves into the rock mass,were limited by the deeper groundwater levels encountered in each of these boreholes.Accordingly,acoustic surveys were conducted below a depth of approximately 34.5 feet in DH14-11 and 95.5 feet in DH14-12. 3.3.Instrumentation Geologic instrumentation consisting of vibrating wire (VWPs)and standpipe piezometers (SPZs),and the temperature acquisition cables (TACs)were installed in selected boreholes.A total of 11 VWPs,4 SPZs,and 10 TACs were installed in the 2011 through 2014 boreholes. Each of the VWPs and TACs were equipped with data loggers to collect data at regular intervals. In addition,selected historical boreholes were retrofitted with VWPs,TACs,pneumatic piezometer transducers,SPZ monitoring transducers and data loggers. A list of the geotechnical instrumentation installed during the 2011 through 2014 field seasons is presented in Table 3.A list of historical geotechnical instrumentation in the area of the dam and the proposed borrow and quarry areas near the dam site are presented in Table 4.The locations of boreholes containing geotechnical instrumentation are presented on Figure 5.Appendix E Geotechnical Data Report Page 3-5 02/22/15 -zZ ALASKA ENERGY AUTHORITY SUSITNA-WATANA HYDRO AEA11-022 Clean,reliable energy for the next 100 years.1 6-1 434-REP-02221 5 presents as-built depictions for geotechnical instrumentation installed in the 2011 through 2014 boreholes and historical boreholes retrofitted with new instrumentation equipment. 3.3.1.Piezometers Piezometers were installed in each of the boreholes advanced during the 2011 through 2014 field seasons.VWPs were installed in boreholes DH12-1 through DH12-6,DH12-8,and DH14-9b through DH14-12.Each VWP was fitted with a single channel data logger.SPZs were installed in G11-DHO1 through G11-DH03,and DH12-7.These SPZs were monitored using hand held water level indicators during instrumentation monitoring field efforts. 3.3.2.Ground Temperature Monitoring TACs were installed in boreholes DH12-1 through DH12-4,DH12-6,DH12-8,and DH14-9b through DH14-12.Each of the TACs were fitted with a data logger to collect temperature data over time.Additional TACs with data loggers were installed in existing boreholes DH-24, DH-28,BH-03,and DH84-06 during the 2012 field season.TACs installed during the 2012 field season (DH12-1 through DH12-4,DH12-6,and DH12-8)had a general node spacing of 3,6,10, 20,35,50,75,100,125,150,200,and 250 feet.TACs installed during the 2014 field season (DH14-9b through DH14-12)generally had nodes located at 3,6,9,12,15,20,25,50,75,100, 125,150,200,and 250 feet. 3.3.3.Historical Instrumentation Retrofitting In 2011,Golder performed a review of historical geotechnical reports to identify existing instrumentation at the site including open standpipes,pneumatic piezometers,and thermistor probes (Golder,2011b).Geodetic coordinates of each instrumented site were obtained from the historical boring logs when possible.When coordinates could not be identified on boring logs, historic maps were digitized and coordinates were created. Based on the information obtained during the 2011 assessment,some existing boreholes were selected to be retrofitted with new sensors and data loggers.This work was completed during the 2012 field season. Two historical boreholes were retrofitted to collect groundwater data,DH84-1 and DH84-2.The retrofits included adding pressure transducers to existing pneumatic sensors,adding a VWP to one existing SPZ,and adding self-contained water level data loggers to a SPZ.Pneumatic sensors and VWPs were connected to data logging units installed at the ground surface. Four historical boreholes were retrofitted to collect ground temperature data.TACs were installed in existing tremie pipes,SPZs,or casings of boreholes BH-3,DH-24,DH-28,and Geotechnical Data Report Page 3-6 02/22/15 - -ALASKA ENERGY AUTHORITY SUSITNA-WATANA HYDRO AEA11-022 Clean,reliable energy for the next 100 years.1 6-1 434-REP-02221 5 DH84-6.TAC range in depth from 35 to 100 feet and generally had nodes at depths of 3,6,10, 20,35,50,75,and 100 feet.Each TAC was connected to a data logger that was installed at the ground surface. 3.4.Bulk Samples Bulk samples were collected during the 2011 through 2014 investigations.During the 2011 investigations,approximately 300 pounds of bulk samples were collected from Quarry A for laboratory testing of potential aggregate.Similarly,approximately 200 pounds of bulk samples for laboratory testing were also collected from talus slopes in the area of the left abutment and Quarry M during the 2012 field investigation.Results of the laboratory testing of bulk samples are presented in Appendix F.An estimated 200 pounds of bulk samples were collected from selected locations near the dam site for potential age dating during future laboratory testing programs.

The laboratory testing programs were designed to provide data on the quality of the rock,the engineering properties of the rock material,in order to evaluate the rock foundation and its suitability as a construction material,e.g.,concrete aggregate.These tests are also useful indicators of the suitability of the rock for other uses such as riprap and road surfacing.Testing was conducted in general accordance with either ASTM or ISRM test methods.The laboratory test results are presented in Appendix F.Testing methods used include: *Uniaxial Compressive Strength (UCS)of Intact Rock Core Specimens -ASTM D7012.This test method is used to determine the strength of intact rock core specimens. The rock core samples are placed between two platens and loaded until failure.The peak stress is reported as the unconfined compressive strength.In some instances,strain gauges are attached to the sample to determine Young's modulus and Poisson's Ratio. UCS testing conducted during the 2011 field season was conducted in accordance with ASTM test method D7012-07 Method C.Tests conducted during the 2012 field season were performed in accordance with ASTM test method D7012-07 Method D.Tests conducted as part of the 2014 field season were conducted in accordance with ASTM test methods D7012-14 Method C or D7012-14 Method D. *Point Load Strength Index Text -ASTM D5731.The point load index test is used to provide estimates of the compressive strength of rock for classification purposes.Rock core samples were tested in a diametral test,placed between two platens,and loaded until failure.A constant,K,which is specific to a particular rock unit,is used to relate the point load index to an approximate UCS value.After analysis and comparison with UCS Geotechnical Data Report Page 4-1 02/22/15 a ALASKA ENERGY AUTHORITY SUSITNA-WATANA HYDRO AEA11-022 Clean,reliable energy for the next 100 years 1 6-1 434-REP-02221 5 test results,a K value of 19 was determined to convert point load test results into approximate UCS values.All samples were tested in accordance with ASTM test method D573 1-08. *Brazilian Strength Test -ISRM 1981.The Brazilian Strength test,or Indirect Tensile test,is used to determine the tensile strength indirectly.The sample is compressed diametrically,inducing a tensile force and causing the sample to split.The peak rupture load is then used to calculate the Brazilian tensile strength. «Direct Shear -ASTM D5607.The direct shear test is used to provide estimates of shear strength along an existing joint surface,a saw-cut surface,or two dissimilar surfaces (such as rock and concrete).Test results provide a friction angle and apparent cohesion for the joint or surface being tested.Shearing tests were conducted on rock core samples to evaluate saw-cut surfaces;natural calcite coated surfaces inferred to be an in-situ healed joint;and various degrees of weathered joints having various amount of clay, calcite and/or iron-oxide.All samples were tested in accordance with ASTM test method D5608-08. =Pulse Velocities and Ultrasonic Elastic Constraints of Rocks -ASTM D2845.Pulse velocity is used to determine intact elastic constants of isotropic or slightly anisotropic rock by measuring the speed at which a propagated wave travels through a test specimen. Test results are used to approximate seismic velocities (P-and S-waves),Young's Modulus,Shear Modulus,and Poisson's ratio. «Petrographic Examination including Petrographic Number -ASTM C295 /CSA A23.2-15A.Petrographic examinations are made to:(1)determine the physical and chemical characteristics of the material that may be observed by petrographic methods and that have a bearing on the performance of the material in its intended use;(2) describe and classify the constituents of the sample;and (3)determine the relative amounts of the constituents.Petrographic examinations are described in detail in Section 4.2 of this report. "Modified Mortar Bar Test -ASTM C1260/C1567.The mortar bar test (ASTM test method C1260)provides a way of detecting an aggregate's potential to undergo expansion as a result of alkali-silica reaction when incorporated into a cement mortar. The accelerated mortar bar test (ASTM test method C1567)evaluates the effect of pozzolans and blast furnace slag to control expansion due to alkali-silica reaction. Samples tested as part of the 2011 field investigation were conducted in general accordance with ASTM test method C1260.Samples tested as part of the 2012 investigation program were conducted in general accordance with ASTM test method Geotechnical Data Report Page 4-2 02/22/15 -w-.ALASKA ENERGY AUTHORITY SUSITNA-WATANA HYDRO AEA11-022 Clean,reliable energy for the next 100 years.1 6-1 434-RE P-02221 5 4.2. C1567.These 2012 test specimens were evaluated using varying amounts of both Class C and Class F fly ash.Fly ash replacement values (the portion of the cementitious content comprised of fly ash)consisted of either 35 percent or 45 percent for various samples. Los Angeles Abrasion (Large Size,500 revolutions)-ASTM C131.The Los Angeles Abrasion test is widely used for testing of coarse aggregate for resistance to abrasion using a standardized machine.It is used as an indicator of the relative quality or competence of various sources of aggregate having similar mineral compositions. Soundness,Magnesium Sulfate (5 cycles)-ASTM C88.The magnesium sulfate test evaluates aggregate soundness when subjected to weathering action in concrete or other applications.This is accomplished by repeated immersion in saturated solutions of magnesium sulfate followed by oven drying to partially or completely dehydrate the salt precipitated in permeable pore spaces.The internal expansive force,derived from the rehydration of the salt upon re-immersion,simulates the expansion of water on freezing. Freeze-Thaw Durability (55 cycles)-Modified ASTM D5312.The freeze-thaw durability test is designed to determine the effects of freezing and thawing action on individual pieces of rock and the resistance of the rock to deterioration.The rock is subjected to multiple cycles of freezing and thawing based on the location of the project site.While the ASTM D5312 test standard does not provide a recommended number of freeze-thaw cycles for the Project site,a total of 55 freeze-thaw cycles was selected based on interpolation of the test standard.This method was modified to accommodate samples that were smaller than those recommended by the ASTM standard. Relative Density (Specific Gravity)and Absorption of Coarse Aggregate --ASTM C 127.This test method is used to determine the density and absorption of coarse aggregate particles.Test results provide an average value representing the sample.The sample is oven dried and then soaked for a prescribed duration.The absorption is the increase in the weight of aggregate due to water in the pores of the material,but not adhering to the outside surface of the particles,expressed as a percentage of the dry weight. Petrographic Examination Petrographic examinations were performed to determine the composition of selected rock samples collected during the 2011 and 2012 field investigations.Selected samples were obtained from rock cores,outcrops and talus deposits.Petrographic examinations conducted as part of the 2011 investigations focused on potential construction materials from Quarry A.These samples included four andesite porphyry samples (petrographically classified as altered dacite)and one Geotechnical Data Report Page 4-3 02/22/15 -y.ALASKA ENERGY AUTHORITY SUSITNA-WATANA HYDRO AEA11-022 Clean,reliable energy for the next 100 years.1 6-1 434-REP-02221 5 diorite sample (petrographically classified as altered tonalite).Samples examined from the 2012 field investigation focused on material from Quarry M consisted of diorite (petrographically classified as quartz diorite).Results of the petrographic examinations are presented in Appendix G. Rock type classification in the petrographic examination was based on visual estimates of mineral proportions in hand samples and a cursory review of thin sections.In addition,rock type categories and sub-categories were defined on the basis of mineral composition,grain size,and presence or absence of alteration. The Petrographic Number,or PN,is calculated as part of the petrographic examination.The PN is a numeric index of physical-mechanical quality of a coarse aggregate material.The use of the PN as a measure of coarse aggregate quality was first established in the Province of Ontario (Canada)in the 1950s,and eventually developed into a rapid quality control tool for the assessment of processed gravel aggregates.Correlation of the PN with other physical quality indices indicated that it could serve as a reliable indicator of quality for field samples, production-run materials,and eventually,exploration samples.The PN is based on the relative proportions of various physical-mechanical quality classes,"Good”,"Fair”,"Poor”and "Deleterious”,into which all the particles of a sample are sorted,based upon their physical properties (strength,hardness,toughness,absorption/porosity,weathering).Each quality class is assigned a numeric multiplier (1,3,6,and 10);a PN is calculated for the sample using the relative proportions of each quality class. A theoretically "perfect”sample would thus be classified as containing 100%"Good”quality material,and would have a PN of '100',i.e.,100 x 1 =100,while the theoretically worst sample would have a PN of 1000 (100%x 10 =1000).In normal use,PNs for good-quality commercially produced aggregates tend to have PNs that range from near 100 to around 150. Concrete aggregates,railroad ballast,and Superpave asphalt aggregates would likely have PNs that fall below 130 to 140,while road base aggregates,for example,might have PNs that are somewhat higher,since the demands required would tend to be somewhat less stringent. Materials proposed for use as aggregates would have PNs that generally would not exceed 200.

Instrumentation monitoring site visits occurred during the 2012 and 2014 field seasons.Two monitoring site visits were conducted during the summer and fall of 2012.Monitoring was not conducted during the 2013 field season due to land access restrictions.Monitoring resumed in 2014 with one summer site visit and one fall site visit. The first 2012 site visit occurred between August 2 and August 8.Groundwater level and ground temperature measurements were obtained at 24 selected historical boreholes.The historical borehole sites visited are presented in Tables 4 and 5.The team also collected groundwater level measurements from the three 2011 drill holes in Quarry A.In addition, groundwater and temperature data were downloaded from the 2012 instrumentation data loggers that had been established at the time of the field visit (DH12-1 and DH12-2). The second 2012 field visit took place between October |and October 3.Data from selected historical instruments,the 2011 boreholes,and the 2012 boreholes were collected during the second instrumentation field visit.Additional details of the 2012 instrumentation monitoring site visits are presented under a separate technical memorandum (Golder 2013a). Instrument monitoring site visits were foregone during the 2013 field season due landowner land access restrictions.Field teams collected and removed monitoring devices from lands on November 6"and 7"at the request of the land owners.Batteries in some of the instrumentation monitoring devices had run out prior to this site visit.Accordingly,significant data gaps occurred prior to and following the November 2013 site visit.A summary of the data collected from the geotechnical instrumentation devices once removed from the site were presented under a separate technical memorandum (Golder 2013b). The key objectives of the 2014 instrument monitoring program were to re-install the instrument monitoring devices that were removed during the 2013 field season and to collect groundwater and ground temperature data over the summer.Instrumentation was re-established during a field visit conducted in June 2014.A second field visit was conducted between October 8 through October 12,2014 to download data,replace data logger batteries,and observe water levels in SPZs.

The Talkeetna Mountain province is comprised of four sub-provinces,consisting of the Fog Lake Upland,the Chulitna Mountains to the northwest,the central Talkeetna mountains to the southeast,and the Clearance Lake Uplands to the east.The Watana site is located within the Fog Lake Upland sub-province.This sub-province is characterized by a northeast-southwest trending terrace with rolling hills and thin layers of sediment overlying shallow rock.The overlying soil mantle is believed to have formed from repeated glaciations (Acres,1982a).The terrace is bisected by a deep U-shaped valley formed by the Susitna River,which is in excess of 800 feet deep at the location of the Watana site.Thicker soil layers are present locally within the Fog Lake Upland where relict channels and other erosional features have been filled in by Quaternary sediments. 6.2.Regional Geology The Project is located in the geologically and tectonically complex Talkeetna Mountains.The mountains consist of glaciated,mountainous terrain,with peaks on the order of 6,000 to 9,000 feet high.The mountain range is also characterized by broad rolling uplands with steeply incised river valleys (Csejtey,1974).The orogeny of the Talkeetna Mountains has resulted from the subduction of the Pacific tectonic plate below the over-riding North American plate.This subduction fault is commonly referred to as the Alaska-Aleutian Subduction Zone.Over geologic time,movement along this subduction zone has accreted a number of structural blocks, or terranes,onto the North American continent.The Talkeetna Mountains are comprised of three such terranes consisting of the North Talkeetna Flysch Terrane,the Peninsular Terrane,and the Wrangellia Terrane.The Project is located within the North Talkeetna Flysch Terrane near the southwest boundary with the Wrangellia Terrane (Fugro,2011). The region is underlain by bedrock which is comprised of a sequence of Cretaceous shale (regionally metamorphosed to argillite)and lithic greywacke sandstone of the Kahiltna assemblage (Csejtey et al.,1978).The Kahiltna assemblage is regionally intruded by small Geotechnical Data Report Page 6-1 02/22/15 -y.ALASKA ENERGY AUTHORITY SUSITNA-WATANA HYDRO AEA11-022 Clean,reliable energy for the next 100 years.1 6-1 434-REP-02221 5 bodies of Paleocene granites,and granodiorites with minor diorite (Csejtey et al.,1978),between 53.2 Ma (1 Ma =1 million years)to 64 Ma during the late stages of accretionary tectonics from terrains that drifted northwestward and sutured onto the North American plate (Csejtey 1978). Diorite and quartz diorite bedrock underlies the dam site and lower reservoir area and upstream for a short distance (Acres 1982b).Further upstream,the reservoir is underlain by Paleozoic and Cretaceous meta-sedimentary bedrock.Other bedrock units include Paleocene to Miocene subaerial volcanic rocks and related shallow intrusives (Woodward-Clyde Consultants,1980), including andesite porphyry,mafic to felsic dikes,and basalt flows (Acres 1982b).Figures 6a and 6b present the geology of the region surrounding the Project. 6.3.Geologic Units 6.3.1.Bedrock Geology 6.3.1.1.Diorite The dam site is primarily underlain by Tertiary volcanic intrusions that range in composition from diorite to granodiorite to quartz diorite.The bedrock is medium to dark green gray,fine to medium grained,generally strong to very strong,competent,and fresh to slightly weathered. The more intense weathering was observed in the upper portions of the rock and along discrete fractures within the rock formation.Discontinuities within the diorite are typically moderately to widely spaced,but are intermittently closely to very closely spaced in localized areas.In outcrop,joints are typically tight to open,although they are mostly tight at greater depths,rough to smooth and sometimes are slickensided,planar,and some contain iron stains or carbonate coatings or deposits.At depth,weathering locally can occur in areas of highly fractured rock, and the fractured rock may also contain shear zones and/or have been hydrothermally altered. Discontinuities at depth are commonly healed with carbonate. 6.3.1.2.Andesite Bedrock directly downstream of the dam site and in Quarry A consists of extrusive volcanics, mostly andesite porphyry.The andesite is similar in chemical composition to the diorite and is generally dark gray to black,slightly weathered to fresh,strong to very strong,competent and in places contains diorite xenoliths.This rock contains unfilled joints and veins with quartz, calcite,clay/silt,and iron oxides.Some discontinuities are very tight to partially open. Xenoliths consisting of volcanic and granodiorite inclusions that is up to 0.2 feet in maximum dimension.

Intermediate thickness of overburden on the order of 6 to 17 feet was encountered in boreholes targeting geologic features and on the upper left abutment. Overburden observed in the 2011 through 2014 boreholes were generally consistent with descriptions of those encountered in historical boreholes at the dam site.Overburden depths encountered in boreholes near the dam site and Quarries A and M are presented in Tables 1 and 3.

There are possible variations in subsurface conditions between boreholes and also with time. Therefore,inspection and testing by a qualified engineering geologist and/or geotechnical engineer should be included during future site investigations,final design and construction to provide corrective recommendations adapted to the conditions revealed during future project activities. Unanticipated subsurface conditions are commonly encountered that cannot fully be determined by a limited number of boreholes or samples.Such unexpected conditions frequently result in additional project costs in order to build the project as designed.Therefore,a contingency for unanticipated conditions should be included in the construction budget and schedule. The work program followed the standard of care expected of professionals undertaking similar work in the State of Alaska under similar conditions.No warranty expressed or implied is made.

Borehole elevations based on this more accurate surface model are presented in Table 2 of this report. -yz ALASKA ENERGY AUTHORITY SUSITNA-WATANA HYDRO AEA11-022 Clean,reliable energy for the next 100 years.1 6-1 434-R EP-01 1 21 5 2011 GEOLOGIC LOG LEGEND sLB[ANC_SOIL_LEGEND]2/16/12UNIFIED SOIL CLASSIFICATION (ASTM D 2487-00) MATERIAL CRITERIA FOR ASSIGNING SOIL GROUP NAMES GROUP TYPES AND GROUP SYMBOLS USING LABORATORY TESTS SYMBOL SOIL GROUP NAMES &LEGEND 5 GRAVELS CLEAN GRAVELS Cy24AND1sC,53 GW WELL-GRADED GRAVEL Q oO o29lbJ££@O: 0 350%OF COARSE |T'NES Cy <4 ANDIOR 1 >C,>3 GP |POORLYGRADED GRAVEL |,ay Sa2=z FRACTION RETAINED BN T 8 529fa)Ww ON NO 4.SIEVE GRAVELS WITH FINES CLASSIFY AS ML OR CL GM SILTY GRAVEL ©(MP ox =aasS FINES =y 2 a >12%FINES FINES CLASSIFY AS CL OR CH GC CLAYEY GRAVEL PK<<4ers°w .SANDS CLEAN SANDS Cy26AND15C,53 SW WELL-GRADED SAND 5 i=]neQSz<5%FINES Bee re Cy <6 AND/OR 1>C,>3 SP POORLY GRADED SAND 223o*250%OF COARSE 8 &>1S)FRACTION PASSES =e 2sONNO4.SIEVE |SANDSAND FINES |"NES CLASSIFY AS ML OR MH SM |SILTY SAND BES 0,212%FINES FINES CLASSIFY AS CL OR CH sc CLAYEY SAND " SILTS AND CLAYS ORGANIC CLAY OR SILT |4 CL LEAN CLAY 5 =5 =7)be gp.(OH,OL)if cH a S528PJ=|Lt (oven dried)A oo oD9mwLIQUIDLIMIT<50 +40 |"LL (not dried)<0.75,alg 4s ML SILT 3 .as|x”*[4s 5D8oanedot|ORGANICCLAYORSILT [152 22Wla>aac teen ee KE --|g 35 8Sagres!se"a ge22%|sitsanpciays |Q Zab oC "CH |FAT CLAY Wp ikkO893TaMHgeesweaonj&8H ?2 z LIQUIDLIMIT 250 |4 ML 7 MH ELASTIC SILT 5258Le42.a .=x os°o %4%8 70 0 9%|OH |ORGANICCLAYORSILT |[Z7)J2®85LIQUIDLIMIT(LL)=> HIGHLY ORGANIC SOILS PRIMARILY ORGANIC MATTER,DARK IN COLOR,AND ORGANIC ODOR =PT.PEAT Ro Gravels or sands with 5%to 12%fines require dual symbols (GW-GM,GW-GC,GP-GM,GP-GC,SW-SM,SW-SC,SP-SM,SP-SC)De (Dy ?and add "with clay"or "with silt'to group name.If fines classify as CL-ML for GM or SM,use dual symbol GC-GM or SC-SM.Cys Dio C,=D.xDOptionalAbbeviations:Lower case "s”after USCS group symbol 19 ®60Genoteseither"sandy”or with sand and .RELATIVE DENSITY/CONSISTENCY ESTIMATEg"denotes either "gravelly"or "with gra USING STANDARD PENETRATION TEST (SPT)VALUES CRITERIA FOR DESCRIBING COHESIONLESS SOILS ®COHESIVE SOILS”UNCONFINEDMOISTURECONDITION(ASTM D 2488-00)N,(BLOWS/N,(BLOWS/COMPRESSIVERELATIVEDENSITY'4 (c)CONSISTENCY (c)(a)DRY |ABSENCE OF MOISTURE,DUSTY,DRY TO THE TOUCH FOOT)FOOT)"_STRENGTH (TSF) MOIST |DAMP BUT NO VISIBLE WATER VERY LOOSE 0-4 VERY SOFT 0-2 0-0.25 WET VISIBLE FREE WATER,USUALLY SOIL IS BELOW LOOSE 4-10 SOFT 2-4 0.25 -0.50 WATER TABLE COMPACT 10-30 FIRM 4-8 0.50 -1.0 DENSE 30 -50 STIFF 8-15 1.0-2.0 COMPONENT DEFINITIONS BY GRADATION VERY DENSE OVER 50 VERY STIFF 15 -30 2.0-4.0 COMPONENT SIZE RANGE :---_,en 30 oven 4.0{a)Soils consisting of gravel,sand,and silt,either separately or in combination possessing no characteristicsBOULDERSABOVE12IN.of plasticity,and exhibiting drained behavior.y 9 COBBLES 3 IN.TO 12 IN.(b)Soils possessing the characteristics of plasticity,and exhibiting undrained behavior.

Clear Ice is transparent and contains only a moderate number of air bubbles. Cloudy Ice is translucent,but essentially sound and non-pervious Friable denotes a condition in which material is easily broken up under light to moderate pressure. Granular Ice is composed of coarse,more or less equidimensional,ice crystals weakly bonded together. Ice Coatings on particles are discernible layers of ice found on or below the larger soil particies in a frozen soil mass.They are sometimes associated with hoarfrost crystals, which have grown into voids produced by the freezing action. Ice Crystal is a very small individual ice particle visible in the face of a soil mass. Crystals may be present alone or ina combination with other ice formations. Ice Inclusions are individual ice masses visible in the face of a soil mass.Inclusions may be present alone or in a combination with other ice formations. Ice Lenses are lenticular ice formations in soil occurring essentially parallel to each other,generally normal to the direction of heat loss and commonly in repeated layers. Ice Segregation is the growth of ice as distinct lenses,layers,veins and masses in soils,commonly but not always oriented normal to direction of heat loss. Massive Ice is a large mass of ice,typically nearly pure and relatively homogeneous. Poorly-bonded signifies that the soil particles are weakly held together by the ice and that the frozen soil consequently has poor resistance to chipping or breaking. Porous Ice contains numerous voids,usually interconnected and usually resulting from melting at air bubbles or along crystal interfaces from presence of salt or other materials in the water,or from the freezing of saturated snow.Though porous,the mass retains its structural unity. Thaw-Stable frozen soils do not,on thawing, show loss of strength below normal,long-time thawed values nor produce detrimental settlement. Thaw-Unstable frozen soils show on thawing, significant loss of strength below normal, long-time thawed vaiues and/or significant settlement,as a direct result of the melting of the excess ice in the soil. Well-Bonded signifies that the soil particles are strongly held together by the ice and that the frozen soil possesses relatively high resistance to chipping or breaking.LIBRARY-ANC|z FROZEN SOIL
