The purpose of the investigation was to identify the engineering properties of the site soils and bedrock necessary for the design of the tower foundations, electrical grounding and buried electrical transmission lines. This report provides the results of the investigation and our geotechnical recommendations for the design and construction of the wind turbine foundations. These are preceded by brief summaries of the performed scope of services, the proposed construction, the existing site conditions, and descriptions of the performed investigation and testing. 2.0 SCOPE OF SERVICES The following services were performed for Black Oak Wind Farm, LLC, herein referred to as Client: · Drilling, sampling and logging of six (6) test borings, one at each of the proposed tower locations for which we were given access. We were denied access to one of the originally proposed seven (7) tower locations, Tower No. 2 as identified on the tower location plan provided by the Client. An additional eight (8) borings were performed to shallow depths to sample soils characteristic of those that will be encountered along the proposed buried electrical transmission cable routes. · Mobilization of a geophysical subcontractor to perform electrical resistivity surveys to provide design criteria for equipment grounding and Multi-Analysis of Surface Wave (MASW) testing to identify the shear wave velocity profiles. Both types of testing were performed at each of the six (6) tower locations for which access was granted. · Laboratory testing to assist in identifying the engineering characteristics of the site soils. · Preparation of this engineering report presenting the results of the subsurface investigation, laboratory testing, engineering analyses, and our geotechnical recommendations for the design and construction of the foundations for the proposed wind turbine towers. 3.0 PROJECT DESCRIPTION AND DESIGN CONSIDERATIONS The proposed project is to consist of the installation of at least six (6) wind turbines. As noted, seven turbines were proposed, but access was not granted to one of the sites, Tower No. 2 as identified on the plan provided by the Client. 2 We understand that loading from the proposed towers will be similar to those identified in the General Electric document “Technical Specification, Wind Turbine Generator Systems, International, Foundations, Part II of V, Geotechnical Design”. This document identifies preliminary gravity foundation design stresses for two series of turbines. The smaller is identified to have a gravity foundation (mat or raft) with a diameter of approximately 46 feet, peak edge stresses of approximately 4,500 pounds per square foot (psf), and a corresponding mid foundation stress of approximately 3,350 psf. The larger turbine is identified to have a mat diameter of approximately 53 feet, peak edge stresses of approximately 6,000 psf, and mid foundation stress of approximately 4,500 psf. The smaller foundation is identified to have an average dead weight of foundation concrete of 777 tons. The larger foundation is identified to have a foundation dead weight of 942 tons. Both correspond to foundation heights of approximately 6 feet. It is therefore assumed that gravity foundations will bear at a depth of at least 6 feet below grade, but more likely at a depth of 8 feet or more below grade to take advantage of the dead weight of backfill soils above the mat. The tolerable magnitude of differential settlement due to dead loads is identified to be 3mm/meter, or 0.036 inches per foot. The total allowable uniform settlement under gravity loads is identified to be 20mm, or about 0.8 inches. Power generated by the wind turbines will be conducted by buried conduits. 4.0 SITE DESCRIPTION The proposed wind turbines will be located on properties located in close proximity to Black Oak Road in Enfield, New York. The proposed turbine installations span an area measuring slightly in excess of 1 square mile, an area bounded roughly by Weatherby Road on the north and an existing electrical easement located roughly 1000 feet north of Cayutaville Road on the south. The proposed towers are offset distances ranging up to approximately one-half mile on the east and west sides of Black Oak Road. Five of the six tower locations addressed in the investigation are located on the edges of agricultural fields, Turbine Nos. 1, 3, 5, 6 and 7. Tower Nos. 1 and 3 are located on the northeastern end of the site on the edges of gently sloping fields. Surface grades in the area of Turbines 1 and 3 range up to approximately 3 percent based on elevation data from Google Earth. Turbine Nos. 5 and 6 are located in the southeastern end of the site, with 3 Tower No. 5 being located near the crest of a gently sloping ridge. Surface grades in the area of Turbine 5 range up to roughly 5 percent, and surface grades in the area of Turbine 6 range up to approximately 16 percent. Turbine 7 is located in the southwestern end of the site in gently sloping terrain. Surface grades in this area range up to approximately 5 percent. There is a pond located approximately 150 feet north of the Turbine 7 location. The turbine not located on the edge of a field is No. 4. This turbine is located on the gently sloping crest of a ridge on the western end of the proposed site. This area is lightly vegetated with brush and occasional small trees. Surface grades over the footprint of a mat foundation range up to approximately 3 percent. Regionally, the ground surface generally slopes down from the southwest to the northeast, with surface grades ranging from a high elevation of approximately 1936 feet on the ridge near B-4 to a low elevation of approximately 1627 feet, again with all elevation data being obtained from Google Earth. No bedrock outcrops were noted in the immediate area of the turbine locations. However, a relic shale quarry was noted in the area northwest of Turbine No. 4. A side hill cut in the quarry was estimated to be in excess of 15 feet in height. No groundwater seepage was observed from the cut. 5.0 SUBSURFACE INVESTIGATION The subsurface investigation consisted of the performance of test borings, electrical resistivity surveys, MASW Survey, and laboratory testing. The following subsections describe the performed subsurface investigation. 5.1 Test Borings Six (6) test borings were performed for the proposed wind turbines, one at each of the proposed turbine locations for which we were given access. These are Tower Nos. 1, 3, 4, 5, 6 and 7. The borings were designated by the turbine number, and their locations are shown on the attached Boring Location Plan, Figure 1. The borings were field located relative to the proposed tower locations identified on an aerial image provided by the Client. The locations identified on the attached plan 4 correspond to the GPS coordinates obtained by Tectonic at the performed boring location using a hand-held GPS unit. An additional eight (8) shallow borings were performed across the site for the purpose of sampling soils for thermal resistivity testing. These borings were located to sample the eight USDA soil classes that are identified to exist along the proposed buried cable routes. These borings were identified by the USDA Soil Class abbreviation, and their locations are shown on the attached Soil Sampling Plan, Figure 2. The borings for the proposed towers were performed by Transtec Drilling Services between the dates of November 19 and November 29, 2012 utilizing an ATV mounted drill rig. The borings were advanced through soil and weathered bedrock using a 3-7/8-inch diameter tricone bit and mud-rotary drilling techniques. The near surface soils were stabilized with 4-inch I.D. steel casing. Standard Penetration Testing was performed with a split-spoon sampler continuously to a minimum depth of 12 feet and at maximum 5-foot spacings thereafter in soil and highly weathered bedrock. The borings were advanced through more competent bedrock using an NX double-tube diamond core barrel. Where bedrock was encountered at a shallow depth, which occurred at Boring B-4 (Tower 4), supplemental probes were performed to identify the variability in bedrock depth over the area of the proposed foundation. At this location, three probes were performed with a split-spoon sampler at approximate 25-foot off-sets from the tower center, each located approximately 120 degrees apart. The borings ranged in depth from approximately 23 feet to 52 feet. Where the borings were terminated at a depth of less than 52 feet, bedrock was encountered and cored for lengths ranging from approximately 3 to 20 feet. The borings were left open over the duration of the investigation to monitor the groundwater level. 5 The borings performed to sample the different soil classes were typically advanced by auger to a depth of 4 feet. Five-gallon samples of soil were obtained from the depth interval from 2 to 4 feet at each location. All drilling operations were observed on a full-time basis by an engineering geologist to confirm conformation of drilling and sampling procedures to the appropriate ASTM Standards. The engineering geologist also collected samples for laboratory testing and prepared logs of the soil, bedrock and groundwater conditions encountered. Copies of the logs are included in Appendix I. 5.2 Electrical Resistivity Surveys Electrical resistivity surveys were performed by ARM Geophysics on November 27th and 28th, 2012. The testing consisted of the performance of two mutually perpendicular Wenner arrays centered as close as possible to the turbine center with electrode spacings of 5, 10, 20, 40, and 60-feet. The testing followed the guidelines of the IEEE81 Guide for Measuring Earth’s Resistivity, Ground Impedance, and Earth Surface Potentials of a Ground System. The results of the electrical resistivity testing are presented in Appendix II. 5.3 Multi-Analysis of Surface Waves (MASW) Survey A MASW survey was performed by ARM Geophysics on November 28th and 29th, 2012 at all six turbine locations. This testing, which yields a vertical profile of the subsurface shear wave velocity for selected depths, was performed in two approximately perpendicular arrays centered as close as possible to the center of the proposed turbine as site conditions would allow. Vertical profiles were obtained at three locations for each array, the center, and approximately 25 feet off the center in opposite directions along the array. This yields six shear wave velocity profiles for each tower location. Shear wave velocity profiles were developed to a minimum depth of 60 feet. The results of the MASW testing are also provided in Appendix II, and recommended shear wave velocities for design purposes are provided in Section 7 of this report. 6 5.4 Laboratory Testing Laboratory testing was performed on selected soil samples to assist in evaluating the engineering properties of the soil. Tests were performed to identify the potential corrosivity of the site soils to buried concrete and steel. These tests consisted of the determination of soil pH and soluble soil sulfate and chloride contents on samples obtained at and above the anticipated bearing depth of the foundations. One sample was tested from each of the proposed turbine locations. The soil pH tests were performed in accordance with ASTM Standard 4972. The water soluble sulfate and chloride content tests were performed in accordance with EPA Standards 375.1 and 325.3, respectively. Testing also included the performance of eleven (11) gradation analyses in accordance with ASTM Standard D422, eight (8) Standard Proctor density tests in accordance with ASTM Standard D698, and two multi point soil thermal resistivity tests in accordance with ASTM Standard D5334. Eight of the gradations and all of the density tests were performed on the samples obtained from the eight USDA Soil Classes that the proposed buried transmission cables will traverse. Soil samples EBB-1 and BAC-1 were selected for the performance of thermal resistivity testing based on the results of this testing as they were identified to roughly bound the density and gradation spectrum of the eight soil classes. The soil resistivity tests were performed at a density corresponding to 90 percent of the Standard Proctor density. Five Atterberg limit tests were also performed on representative glacial till samples. This testing was performed in accordance with ASTM Standard D4318. The results of the laboratory testing are included in Appendix III and discussed in Sections 5 and 6 of this report. 6.0 SUBSURFACE CONDITIONS The encountered subsurface conditions consist, in turn, of a thin layer of topsoil, native glacial till soils, and shale bedrock. The glacial till consists predominately of sandy, gravelly clay and gravelly, clayey sand, and also likely contains cobbles and boulders. The shale 7 bedrock typically has a completely weathered surface layer of varying thickness and it was encountered as shallow as 3.8 feet at boring B-4, and at depths varying from 2 to 3 feet at the probe holes located around boring B-4. Bedrock was not encountered at boring B-7, but based on the MASW survey results, it is estimated to be at a depth of approximately 60 feet at this location. The observed groundwater conditions vary across the project site, with water levels being measured at depths varying from approximately 3 to 26 feet below existing grade. The following subsections provide generalized descriptions of the encountered soil, bedrock and groundwater conditions at the different turbine sites. More detailed descriptions of the subsurface conditions are provided in the boring logs included in Appendix I. A table at the end of this section provides the depth and elevation that bedrock and groundwater was encountered at each tower location. 6.1 Native Glacial Till Soil The native site soils consist primarily of glacial till soils derived largely from shale bedrock. Based on the gradation testing performed, the till has relatively minor variations in gradation and plasticity. Typically, the till either consists of 50 to 60 percent low plasticity clay with sand and gravel contents ranging from roughly 20 to 35 percent, and has the Unified Soil Classification of Low Plasticity Clay (CL), or the combined sand and gravel content exceeds the clay content, and the till has the Unified Soil Classification of Clayey Sand (SC). Occasionally, the gravel content exceeds the sand content, and the till has the Unified Classification of Clayey Gravel (GC). The minimum clay content of the tested samples was approximately 35 percent. The tested till samples were identified to have plasticity indexes ranging from 12 to 17 percent and natural water contents ranging from approximately 7 to 28 percent, with the higher moisture content samples typically occurring within the shallow samples obtained for the eight USDA soil classes. These were obtained following a snow melt event. It is also noted that cobbles and boulder size relic shale rock blocks or rocks of other lithologies can also occur within the glacial till. 8 Standard Penetration Test (SPT) N-values within the till typically ranged from approximately 8 to 30 blows per foot (bpf) indicating consistencies typically varying from stiff to very stiff. Shear wave velocities in the glacial till were highly variable ranging from 600 feet per second to in excess of 2,500 feet per second. In general, the shear wave velocities were consistently lower within the tills of boring B-7, where the soils are often more sandy and gravelly. Soil thermal resistivity testing on the more sandy & gravelly soil sample, sample EBB-1, predicts thermal resistivity ranging from approximately 80 to 170 0C-cm/W over the range of moisture testing on the more clayey sample, BAC-1 predicts thermal resistivity ranging from approximately 70 to 190 0C-cm/W over the tested moisture contents. The tests were performed at moisture contents ranging from approximately the natural moisture content of less than 1 percent. 6.2 Shale Bedrock Bedrock at the site consists of sub-horizontally bedded shale. The depths at which bedrock was encountered are identified in the table at the end of Section 5. These depths correspond to the depth that split-spoon sampler refusal was encountered. This is noted because the transition to bedrock is often gradual with an upper zone being weathered to a stiff to hard gravelly soil consistency. This highly decomposed zone extends to depths ranging up to 10 feet above rock that is sufficiently competent to sample with a core drill. On split-spoon sampling, the weathered bedrock typically breaks into gravel and sand sized shale fragments with varying amounts of low plasticity clay. Rock was core drilled at three locations; boring B-3 from a depth of approximately 20 to 25 feet, B-4 from a depth of 3.5 to 23.5 feet, and B-5 from a depth of 35 to 38.5 feet. The core at borings B-3 and B-5, and the core to a depth of 18.5 feet at boring B-4 is moderately to highly weathered and moderately to highly fracture, with fracture spacings typically being less than several inches. The rock is typically characterized as being moderately hard, except in the upper core intervals of boring B-4, which were characterized as being moderately hard to soft. The RQD (Rock Quality Designation, which is the cumulative sum of the lengths of core pieces 4 9 inches or longer divided by the length of the core interval, and expressed as a percentage), was zero for all of the core intervals except for the interval from 13.5 to 18.5 at boring B-4, which had an RQD of 6 percent. The interval from 18.5 to 23.5 at boing B-4 was also highly to moderately fractured, but is less weathered being moderately to slightly weathered. Based on the RQDs of the rock core samples, all of the cored rock has a very poor rock mass rating. The core recoveries were typically 100 percent. The results of the probes performed to identify the variation in bedrock depth at Turbine 4 showed that weathered bedrock varies from an approximate depth of 2 to 3.8 feet over the area of the proposed turbine foundation. Shear wave velocities in the shale were also highly variable ranging from roughly 2,000 fps to in excess of 5,000 fps. 6.3 Groundwater Water was measured in the borings at the depths identified in the table below. Due to the generally low permeability of the glacial till soil and the fact that drilling fluids were introduced into the borings during both rotary drilling and rock core drilling, the recorded groundwater levels may not reflect the actual conditions. It is noted that the deepest recorded water levels were generally associated with the borings where the duration between drilling and the final water level reading were longest. It is also noted that drilling fluids were identified to be lost during the bedrock coring at boring B-5, and this corresponds to the deepest recorded water level, which was 26 feet. At boring B-4, the bedrock was relatively impermeable and water introduced during drilling did not subside below a depth of 1 foot over the duration of observation. Electrical resistivity test results provide an estimate of groundwater depth as the soil and bedrock resistivity typically decreases significantly at the groundwater table or the saturated capillary zone above the groundwater table. Based on the results of this testing, it is estimated that the static groundwater table is below a depth of 20 feet at Turbine 1, between a depth of 10 and 20 feet at Turbines 3, 4, 5 and 6, and at an approximate depth of 20 feet at Turbine 7. 10 It should be noted that groundwater levels will fluctuate with variations in rainfall and with season. Also, the site soils have relatively low permeability. Therefore, shallow perched water conditions should be anticipated following rain or snow-melt events.

Bedrock depth estimated from MASW survey results. 7.0 SEISMIC SITE COEFFICIENTS AND LIQUEFACTION POTENTIAL As part of our investigation, we have evaluated the seismic classes of the tower sites and the appropriate site coefficients for use in seismic design. Based on the results of the subsurface investigation, the tower sites fall under two site classes. Tower sites 1, 6 and 7 fall under Site Class C, which is very dense soil and soft rock. Tower Sites 3, 4 and 5 fall under Seismic Site Class B, which is bedrock. The tower sites falling under Site Class C (Nos. 1, 6 and 7) have maximum spectral response accelerations at short periods (SmS) equal to 0.15g and at 1-second periods (Sm1) equal to 0.095g. The tower sites falling under Site Class B (Nos. 3, 4 and 5) have maximum spectral response accelerations at short periods (SmS) equal to 0.125g and at 1-second periods (Sm1) equal to 0.056g. 11 Liquefaction of soils can be caused by a strong vibratory motion due to earthquakes. Both research and historical data indicate that loose, granular soils saturated by a shallow groundwater table are most susceptible to liquefaction. Liquefaction occurs when an earthquake and associated ground shaking of sufficient duration results in the loss of grain- to-grain contact due to a rapid increase in pore-water pressure, causing the soil to behave as a fluid for short periods. Based on the results of the subsurface investigation, the site soils are not subject to liquefaction due to their cohesive nature and stiff consistency. 8.0 DISCUSSION AND CONCLUSIONS In general, the site conditions are favorable for the proposed wind farm construction. Both the glacial till soils and the weathered shale bedrock provide suitable support for the standard sized gravity foundations identified in Section 3. Also, due to the very shallow depth of bedrock at the location of Tower 4, this site is suitable for the use of an anchored foundation, which can significantly reduce the required weight of the foundation. Rock at the other tower locations is believed to be too deep to cost effectively utilize anchored foundations. This is because the foundation needs to bear entirely on competent rock in order to have strain levels that are compatible with tensioned rock anchors. Recommendations for the design of gravity foundations as well as foundations secured to bedrock utilizing high strength rock anchors are provided in Section 9 of this report. Other conclusions that can be made regarding the proposed construction include the following: · The site soils are not subject to liquefaction · Test results indicate that the plasticity indicies of the soils range from approximately 10 to 17 percent. This indicates that the site soils are non-expansive. · The site soils are not considered corrosive to buried concrete and steel. This assessment is based on the pH of the soil samples typically being either neutral to slightly alkaline. The most acidic sample had a pH was 6.15. Generally, pH levels above 5.5 are considered to be non-corrosive. The soluble sulfate and chloride contents were typically less than their detectable limits. Exceptions occur for the sulfate content for the 0 to 2 foot deep sample at Tower 1 and the 4 to 6 feet deep sample at Tower 7, where 41.9 and 38.3 ppm were recorded, respectively. However, these quantities are considered negligible per the American Concrete Institute (ACI), and Type I or II cements are appropriate for use at the site. Another exception is that a soluble chloride content of 84.1 ppm was recorded for the 0 to 2 foot sample at Tower 1. However, chloride contents less than 500 ppm are 12 considered to be non-corrosive to reinforced concrete (Department of Transportation, Division of New Technology and Materials Research, California Test 532, 1993). · The thermal resistivity of the site soils are predicted to vary from approximately 75 to 136 0C-cm/W over the soil moisture contents expected to be encountered at the site. The high value corresponds to a moisture content of 3 percent and is recommended for design purposes. · The glacial till site soils are considered unsuitable for use as structural fill due to their high clay and silt contents, and they are often moisture sensitive, being difficult to place if the moisture conditions are not optimal. They are therefore not recommended for use as fill beneath the foundations should fill be required. They can be used as backfill around the sides and placed over the top of gravity or anchored mat foundations, however. It is noted that of the eight soil samples obtained from depths of 2 to 4 feet and tested for Standard Proctor density, only two had moisture contents within two percent of the optimum moisture contents. The remaining six had moisture contents ranging from 3 to 8.3 percent over optimum. Therefore, if similar moisture conditions were encountered at the time of construction, much of the soil would need to be dried to achieve adequate compaction, and this can result in construction delays when these materials are used for fill. Structural fill should be import material meeting the gradation requirements provided in Section 10. · The glacial till soils can be excavated with standard heavy duty excavators or dozers. Based on the Caterpillar Handbook of Ripping (8th Edition), shale with a compressional wave velocity of 7,400 feet per second (fps) can be ripped with a D9 Dozer equipped with a ripping bar. A 7,400 fps compressional wave velocity approximately correlates with a shear wave velocity of approximately 4,270 fps. Based on the shear wave velocities from the MASW survey at Tower 4, the rock to a depth of at least 10 feet is considered rippable. Excavator mounted hydraulic hammers can also be used to efficiently break-up the rock. · Based on the groundwater observations made during the performance of the investigation and observations of the regional topography, groundwater is not anticipated to impact the design of Turbine Nos. 4 and 7. Turbine 4 is located relatively high on a ridge. Turbine 7 falls within an apparent buried valley that contains more permeable till soils, and groundwater was recorded at a greater depth at this location. At the other turbine locations, perched water was recorded at relatively shallow depths, or in the case of Tower No. 5, the relatively deep groundwater reading of 26 feet is attributed to the draining of the water within the boring within the more permeable bedrock that was encountered at this location. Although the water in these area is perched, it can still impact foundation design as it reduces the effective weight of the gravity foundation and the backfill soils. In order to be certain that excess pore pressure does not develop beneath the foundations at these locations, it is recommended that a gravel drainage blanket be placed beneath the mat foundations and that an outlet drain be installed to discharge water at a sufficient distance downslope from the turbine that the water can drain by gravity. This is discussed in more detail in Section 9. 13 · Subgrades consisting of the native site soils will be sensitive to disturbance. Therefore, subgrades consisting of the native soils without the above described drainage blanket should have a minimum 4-inch thick layer of concrete placed to protect the subgrade during placement of formwork and steel reinforcement. 9.0 RECOMMENDATIONS The following sections provide our geotechnical recommendations for design and construction of the proposed foundations. The recommendations are based on our understanding of the proposed project as summarized in Section 3 of this report, and the results of the subsurface investigation as described previously. It is noted that if the proposed Turbine locations change, Tectonic will need to confirm the validity of the provided recommendations. This is due in part to the locally abrupt variations in bedrock depth identified by the borings and MASW surveys. 9.1 Foundation Design Criteria Foundations for the proposed wind turbine should bear on moderately stiff to very stiff glacial till or weathered shale bedrock. Foundations bearing on soil should bear at a minimum depth of 54 inches below proposed finish grades for frost protection unless a greater embedment is required based on the local jurisdiction. Foundations bearing on bedrock (Turbine 4) should bear at a minimum depth of 3 feet below proposed finish grade, or deeper as required to fully bear on rock of suitable quality as discussed in Section 10. The following criteria should be used to design both the gravity and rock anchored foundations. Recommendations for the design of the rock anchors are provided in Section 9.2.

Deflections based on the design shear modulus shall determine the service limit. Foundations designed based on the preceding criteria can be expected to have differential settlements under gravity loads less than the identified limit of 3mm per meter and a total uniform settlement less than the identified limit of 20mm. With the incorporation of the drainage blankets at Turbine Nos. 1, 3, 5, and 6, the design high groundwater table can be assumed to coincide with the elevation of the drainage blanket. The design high groundwater tables at Towers 4 and 7 can be assumed to be at a depth of 15 feet. 9.2 Rock Anchor Design Criteria Rock anchors used to resist the overturning loads on the turbine foundations should be designed and load tested in accordance with the latest requirements of the Post Tensioning Institute. Bar anchors should have a minimum free stressing length of 10 feet and should consist of minimum grade 150 deformed bars such as manufactured by Williams Form Company or Dywidag Systems International. Standard anchor sizes range from 1-inch to 1-3/8-inch diameters. Anchors should be installed in holes having a minimum diameter of 4-inches. The anchor size should be selected based on the magnitude of the overturning loads, and the lock-off load should be a maximum of 60 percent of the ultimate strength of the selected bar. The rock bolt anchor zone should be designed assuming an allowable rock-grout bond strength of 40 pounds per square inch (psi). However, the anchor zones should have a minimum length of 5 feet. The grout should have a minimum 28-day unconfined 16 compressive strength of 4,000 psi. The group capacity of the rock anchors should be evaluated by the geotechnical engineer. The anchor zones lengths may need to be extended following this review. At least one rock anchor should be performance tested. The remaining rock anchors should be proof tested. 9.3 Drainage Blanket Design Drainage blankets, where required, should consist of an approximately 12-inch thick layer of ¾-inch washed crushed stone. The drainage blanket should be isolated from the native soils using Mirafi’s 140N non-woven filter fabric or an approved equal. The filter fabric should be wrapped around the sides and lapped over the top of the drainage blanket for such a distance that the concrete of the mat foundation overlies the fabric by a minimum distance of 2 feet. The drainage blanket should be positively drained with a minimum 6-inch diameter pipe out-letting downslope at a location that is safe from damage from tillage or other sources and can be periodically inspected. The outlet of the drain should have a rodent guard. 9.4 Permanent Cut and Fill Slopes Permanent fill slopes constructed from the site soils should have a maximum slope of 2.5 Horizontal to 1 Vertical. Permanent cut slopes in the native site soils should have a maximum slope of 2 Horizontal to 1 Vertical. Permanent cut slopes in the weathered shale bedrock should have a maximum slope of 1 Horizontal to 1 Vertical. 10.0 EARTHWORK CONSTRUCTION CRITERIA The following sections provide our recommendations regarding earthwork, fill placement and subgrade preparations. 10.1 Subgrade Preparation-Soil Subgrades Final excavation to the subgrade elevation should be performed with a grading bucket mounted on an excavator or a standard excavator bucket with a steel plate welded over the teeth of the bucket to minimize disturbance to the subgrade soils. The subgrades should be inspected by the geotechnical engineer. Any soil deemed unsuitable by the geotechnical engineer should be removed as directed by the geotechnical engineer. Over-excavated areas should be backfilled with concrete fill 17 or crushed stone. On turbine sites requiring a drainage blanket, filter fabric should be placed over the subgrade after the subgrade has been approved and then the clean crushed stone should be placed over the subgrade to protect the subgrade from foot and construction traffic. A 4-inch layer of lean concrete should be placed over the inspected and approved turbine subgrade that does not require a drainage blanket (Turbine 7). Concrete should have a minimum 28-day compressive strength of 2,000 psi. Soil subgrades should also be protected from the effects of frost. Insulating blankets and/or heaters should be used as required to protect the subgrades. 10.2 Subgrade Preparation – Rock Subgrades The subgrade of the rock bearing foundation (Turbine 4) should be prepared by removing all soil and loose rock fragments resulting from excavation activities. Bedrock subgrades should be prepared approximately level. Lean concrete, having a minimum 28-day compressive strength of 2,000 psi, may be used to fill undulations in the bedrock surface, but should not be used to level a consistently-sloping bedrock surface due to the shear forces which could develop at the concrete- bedrock interface. Rock subgrades should be inspected by a geotechnical engineer to identify potential soft zones or undesirable fracture planes within the subgrade. Any areas deemed unsuitable by the geotechnical engineer should be removed as directed by the geotechnical engineer and replaced with lean concrete fill. 10.3 Construction Dewatering Perched water seepage is anticipated during foundation construction, especially following periods of rainfall or snow melt. As the site soils are susceptible to disturbance, infiltrating seepage and surface water should be diverted from the subgrade area prior to the placement of the gravel drainage blanket or protective concrete pad. If required, dewatering should be performed to maintain the water level at least 2 feet below the deepest excavation. 18 10.4 Fill and Backfill Materials The on-site soils may be used as fill over the top and along the sides of the foundations provided the moisture content of the fill does not vary by more than 2 percent of the optimum moisture content. It should be noted that minor fluctuations in the moisture content of the soil will affect the ability of contractors to properly compact these soils, and construction delays should be anticipated during periods of wet weather. If import fill is required, it is recommended that relatively impermeable fill be used to minimize water infiltration and the ponding of water around foundations that are not constructed on a drainage blanket. Import fill should contain no particles exceeding 4 inches in the largest dimension, should contain no organic matter, and should have the Unified Soil Classification of CL, SC or GC. All fill should be compacted to at least 97 percent of the maximum dry density as determined by the Standard Proctor test (ASTM D698). The water content of the fill should be within 2 percent of the optimum water content. The required lift thickness will vary depending on the type of compaction equipment used. A geotechnical engineer with appropriate field and laboratory support should inspect and approve all materials for use as fill, and test backfill materials for compliance with the recommended compaction. 11.0 CONSTRUCTION MONITORING A geotechnical engineer familiar with the existing subsurface conditions and having the appropriate laboratory and field testing support should be engaged by the Owner to observe that all earthwork is performed in accordance with the specifications and the design criteria outlined in this report. The following work should be performed under the supervision of a geotechnical engineer: · Foundation subgrade preparation · Rock anchor installation and load testing · Fill placement and compaction · Dewatering 19 All materials proposed for use as soil fill should be tested and approved prior to delivery to the site. Additionally, all fill materials should be tested as they are being placed to verify that the required compaction is achieved. We further recommend that the project plans and specifications be reviewed by the geotechnical consultant prior to final completion of the bid documents. It should be noted that upon review of those documents, some recommendations presented herein may be revised or modified. 12.0 LIMITATIONS Our professional services have been performed using that degree of care and skill ordinarily exercised under similar circumstances by reputable geotechnical engineers and geologists practicing in this or similar situations. The interpretation of the field data is based on good judgment and experience; however, no matter how qualified the geotechnical engineer or detailed the investigation, subsurface conditions cannot always be predicted beyond the points of actual sampling and testing. No other warranty, expressed or implied, is made as to the professional advice included in this report. The recommendations contained in this report are intended for design purposes only. Contractors and others involved in the construction of this project are advised to make an independent assessment of the soil, bedrock, and groundwater conditions for the purpose of establishing quantities, schedules and construction techniques. This report has been prepared for the exclusive use of Black Oak Wind Farm LLC for the specific application to the proposed wind farm project described in this report. We recommend that prior to construction, Tectonic review the project plans and specifications. It should be noted that upon review of those documents, some recommendations presented herein might be revised or modified. In the event that any changes in the design or location of the proposed structures are planned, Tectonic shall not consider the conclusions and recommendations contained in this report valid unless reviewed and verified in writing. It is further recommended that Tectonic be retained to provide construction monitoring and inspection services to ensure proper implementation of the recommendations contained herein, which would otherwise limit our professional liability.

Murphy, PE Senior Geotechnical Engineer TECTONIC Engineering 70 Pleasant Hill Road P.O. Box 37 Mountainville, NY 10953 Re: Final Report - Geophysical Investigation Black Oak Wind Project Enfield, New York ARM Project 12525 Dear Mr. Murphy: ARM Geophysics (ARM) has prepared this report for TECTONIC Engineering (TECTONIC) to document the results of the geophysical surveys performed at six proposed wind turbine locations that are part of the Black Oak Wind Project located in Enfield, New York. The objectives of the geophysical surveys are to determine the shear velocity of the soils as well as the soil resistance prior to installation of the foundations for the wind turbines. The project has seven planned turbines; however, property access was not available for Turbine #2, and as a result, ARM performed the geophysical surveys at six proposed turbine locations. The locations of the proposed wind turbines surveyed during this investigation are shown on Figure 1. GEOPHYSICAL SURVEYS MULTI-ANALYSIS OF SHEAR WAVE (MASW) Seismic surveys are able to discriminate between and among materials with relatively different physical properties (i.e. density), based on the velocity of the seismic wave as it travels through each discrete layer. In general, the more rigid the material, the faster the wave will travel through it. Propagation velocity (also known as phase velocity) of surface waves is frequency (wavelength) dependent. This property is known as dispersion. The dispersiveness of soils is determined mainly by the vertical variation in shear wave velocity (Vs). By recording fundamental-mode Rayleigh waves propagating from the source to receiver, the dispersive properties directly beneath the seismic spread can be measured and represented by a curve (dispersion curve). This ARM Project 12525 2 December 21, 2012 A R M G e o p h y s i c s curve is used to estimate the vertical variation of Vs (1-D Vs profile) through a process called inversion. The MASW method utilizes pattern-recognition techniques. It employs multiple receivers (geophones) equally spaced along a linear survey line and measures the travel-times of seismic waves generated by an implosive source (e.g., sledge hammer). This approach allows recognition of the various propagation characteristics of the seismic wavefield. Once the dispersive properties of the fundamental mode Rayleigh waves are identified (via pattern recognition), a corresponding signal curve is extracted and used in the inversion of a 1-D Vs profile. This profile best represents the vertical Vs distribution at the middle of the receiver spread. By moving the same shot-receiver configuration incrementally along a preset survey line, multiple measurements can be made, each producing a 1-D Vs profile that, when all gathered together, is used to construct a 2-D Vs cross-section along the survey line. MASW has been used to map bedrock topography, identify bedrock fractures, abandoned mine workings, waste pits and trenches, and evaluate sink activity (e.g., voids, pinnacles, zones of enhanced weathering) to depths upwards of approximately 100 feet below ground surface (BGS). Unlike refraction, MASW is not constrained by velocity inversion (high speed layer overlying a lower speed layer), and it can be used in urbanized environments where noise associated with vehicle traffic and buried utilities that typically mask body waves do not significantly impact the robust (larger amplitude) surface waves. The MASW method was utilized to obtain shear wave velocities to a depth of approximately 60 feet below the existing grade. At each turbine, ARM collected two traverses of data that were oriented approximately north-south and west-east. Due to heavy brush and other site conditions, the locations of the traverses were as close to the center of the planned turbine pad as possible. Whenever possible, a shot was recorded at 25 feet from the center of the turbine on each side and at the center of the turbine. The MASW data were processed using the SurfSeis® processing software. The results and one- dimensional graphs of the shear velocities and the corresponding depths are discussed below. FIELD RESISTIVITY SURVEY At each of the six turbine locations, soil resistances were recorded along two traverses which were oriented perpendicular to each other. For each measurement/data point, the probes were driven into the ground at equal electrode spacings (using the 4-Point Resistivity Measurement Procedure). For this project, the electrode spacings were set at 5, 10, 20, 40, and 60-feet in each direction for a total of 10 data points at each proposed turbine location. The resistance value (in Ohms) is measured for each electrode spacing set-up. The soil resistivity (in Ohm-Meters) is calculated using the simplified Wenner formula. The resistivity surveys followed the guidelines of the IEEE81 Guide for Measuring Earth’s Resistivity, Ground Impedance, and Earth Surface Potentials of a Ground System. ARM Project 12525 3 December 21, 2012 A R M G e o p h y s i c s GEOPHYSICAL SURVEY RESULTS Figure 1 shows the locations of the six turbines that were surveyed during this investigation. At each turbine location, there were two seismic/resistivity traverses collected. The following tables summarize the shear velocities and the soil resistance measurements collected from the surveys. Seismic surveys are able to discriminate between and among different materials, based on the velocity of the seismic wave as it travels through each discrete layer. In general, the more rigid the material, the faster the wave will travel through it. The table below describes typical shear (seismic) wave velocities for different earth materials.

Graphs of the measured resistance values versus electrode spacings at each turbine are included in Attachment B. Please note that in the seismic data tables presented below, shot locations A, B, and C are the locations of the three seismic shots recorded along each traverse. Shots A and C were recorded at least 25 feet from the center of the turbine pad, and Shot B was located as close to the center of the turbine pad as possible, given the site conditions.
