Introduction The use of wind energy, one of the oldest forms of harnessing a natural energy source, is now one of the world’s fastest growing alternative energy sources. The United States is committed to the use of wind energy, and over the next several years billions of dollars will be spent on wind power projects. However, as new wind turbine generators are installed around the country, it is important to note that they may pose an interference threat to existing microwave systems and broadcast stations licensed to operate in the United States. Wind turbines can interfere with microwave paths by physically blocking the line-of-sight between two microwave transmitters. Additionally, wind turbines have the potential to cause blockage and reflections (“ghosting”) to television reception. Blockage is caused by the physical presence of the turbines between the television station and the reception points. Ghosting is caused by multipath interference that occurs when a broadcast signal reflects off of a large reflective object—in this case a wind turbine—and arrives at a television receiver delayed in time from the signal that arrives via direct path. Many states and other jurisdictions recognize the need for regulations addressing interference to radio signal transmissions from the wind turbine installations. Specifically, local planning authorities typically require project developers to ensure wind turbines will not cause interference. In some cases they require developers to notify the telecommunication operators in the area of the proposed wind turbine installation. Other factors prompting developers to undertake proactive investigation into potential interference include the need to prevent legal and regulatory problems and the desire to promote goodwill within the community—a good neighbor approach. Comsearch has developed and maintains comprehensive technical databases containing information on licensed microwave networks throughout the United States. Microwave bands that may be affected by the installation of wind turbine facilities operate over a wide frequency range (900 MHz – 23 GHz). These systems are the telecommunication backbone of the country, providing long-distance and local telephone service, backhaul for cellular and personal communication service, data interconnects for mainframe computers and the Internet, network controls for utilities and railroads, and various video services. This report focuses on the potential impact of wind turbines on licensed non-federal government microwave systems. Comsearch provides additional wind energy services, a description of which is available upon request.

Project Information Name: Black Oak Wind Farm County: Tompkins State: New York Total Microwave Paths Paths with Obstructions Total Turbines Turbine Obstructions 2 N/A N/A N/A Methodology Our obstruction analysis was performed using Comsearch’s proprietary microwave database, which contains all non-government licensed paths from 0.9 - 23 GHz 1 . First, we determined all microwave paths that intersect the area of interest2 . The area of interest was defined by the client and encompasses the planned turbine locations. Next, for each microwave path that intersected the project area, we calculated a Worst Case Fresnel Zone (WCFZ). The mid-point of a full microwave path is the location where the widest (or worst case) Fresnel zone occurs. Fresnel zones were calculated for each path using the following formula. ⎟⎠ ⎞⎜⎝ ⎛ +≅ 21 2117.3 dd dd F nRn GHz Where, Rn = Fresnel Zone radius at a specific point in the microwave path, meters n = Fresnel Zone number, 1 FGHz = Frequency of microwave system, GHz d1 = Distance from antenna 1 to a specific point in the microwave path, kilometers d2 = Distance from antenna 2 to a specific point in the microwave path, kilometers For worst case Fresnel zone calculations, d1 = d2 1 Please note that this analysis does not include unlicensed microwave paths or federal government paths that are not registered with the FCC. 2 We use FCC-licensed coordinates to determine which paths intersect the area of interest. It is possible that as-built coordinates may differ slightly from those on the FCC license. Comsearch Proprietary - 2 - October 26, 2011 Enfield Energy LLC Wind Power GeoPlanner™ Licensed Microwave Report Black Oak Wind Farm Comsearch Proprietary - 3 - October 26, 2011 The calculated WCFZ radius, giving the linear path an area or swath, buffers each microwave path in the project area. See the Tables and Figures section for a summary of paths and WCFZ distances. In general, this is the two-dimensional area where the planned wind turbines should be avoided, if possible. A depiction of the WCFZ can be found in the Tables and Figures section, and is also included on the enclosed spreadsheet and shapefiles 3 ,4 . Discussion of Potential Obstructions For this project, turbine locations were not provided; thus we could not determine if any potential obstructions exist between the planned wind turbines and the incumbent microwave paths. If the latitude and longitude values for turbine locations are provided, Comsearch can identify where a potential conflict might exist. 3 The ESRI® shapefiles enclosed are in NAD 83 UTM Zone 18 projected coordinate system. 4 Comsearch makes no warranty as to the accuracy of the data included in this report beyond the date of the report.

Introduction In this report, Comsearch analyzed the off-air television stations whose service could potentially be affected by the proposed Black Oak Wind Farm wind energy project in Tompkins County, New York. Off-air stations are television broadcasters that transmit signals that can be received directly on a television receiver from terrestrially located broadcast facilities. Comsearch examined the coverage of the off-air TV stations and the communities in the area that could potentially have degraded television reception because of the location of the proposed wind energy project. 2. Summary of Results The proposed wind energy project area and local communities are depicted in Figure 1, below. Figure 1: Wind Farm Project Area and Local Communities Enfield Energy, LLC Wind Power GeoPlanner™ Off-Air Television Report Black Oak Wind Farm Comsearch Proprietary - 2 - December 29, 2011 To begin the analysis, Comsearch compiled all off-air television stations1 within 150 kilometers of the wind project area of interest (AOI). Appendix A contains a tabular summary of these stations. A plot depicting their locations appears in Figure 2, below. Figure 2: Plot of Off-Air TV Stations within 150 Kilometers of Project Area TV stations at a distance of 65 kilometers or less are the most likely to provide off-air coverage to the project areas and their neighboring communities. These stations are listed in Table 1, below, and a plot depicting these locations is provided in Figure 3. There are a total of thirty- three database records for stations within approximately 65 kilometers of the wind energy project. Of these stations, eighteen are currently licensed and operating, fourteen of which are 1 Comsearch makes no warranty as to the accuracy of the data included in this report beyond the date of the report. The data presented in this report is derived from the TV station’s FCC license and governed by Comsearch’s data license notification and agreement located at http://www.comsearch.com/files/data_license.pdf. Enfield Energy, LLC Wind Power GeoPlanner™ Off-Air Television Report Black Oak Wind Farm Comsearch Proprietary - 3 - December 29, 2011 low-power digital stations or translators. Translator stations are low-power stations that receive signals from distant broadcasters and retransmit the signal to a local audience. These low- power stations serve local audiences and have limited range, which is a function of their transmit power and the height of their transmit antenna. The remaining four stations in Table 1 operate at full power and are licensed under call signs WETM-TV, WENY-TV, WSKA and WYDC.

Impact Assessment The coverage areas of the fourteen low-power digital stations or translators do not overlap the proposed project area. Figure 4 shows the coverage areas of the licensed low-power stations within 40 km of the project area relative to the project area. Therefore, these stations should not have their reception disrupted by the Black Oak Wind Farm project. Figure 4: Coverage Areas of Low-Power TV Stations within 40 Kilometers of Project Area The four full-power digital stations (WETM-TV, WENY-TV, WSKA and WYDC) may have their reception disrupted in and around the Black Oak Wind Farm project, primarily in locations on the opposite side of the project area, relative to the station antennae. Communities and homes directly to the north and east of the project may have degraded reception of the Elmira and Bath-based stations to the south and west after the wind turbines are installed. However, based on the low number of full-power TV channels available in the immediate vicinity of the project area, it is unlikely that off-air television stations are the primary mode of television service for the local communities. TV cable service, where available, and direct broadcast satellite service (DBS) are more likely the dominant modes of service delivery. Enfield Energy, LLC Wind Power GeoPlanner™ Off-Air Television Report Black Oak Wind Farm Comsearch Proprietary - 6 - December 29, 2011 4. Recommendations Both cable service and direct broadcast satellite service will be unaffected by the presence of the wind turbine facility and may be offered to those residents who can show that their off-air TV reception has been disrupted by the presence of the wind turbines after they are installed. 5.

Introduction In this report, Comsearch analyzed AM and FM radio broadcast stations whose service could potentially be affected by the proposed Black Oak Wind Farm wind energy project in Tompkins County, New York. 2. Summary of Results AM Radio Analysis Comsearch found fourteen database records1 for AM stations within approximately 30 kilometers of the project, as shown in Table 1 and Figure 1.

Impact Assessment Potential problems with AM broadcast coverage are only anticipated when AM broadcast stations with directive antennas are within 3.2 kilometers of wind turbine towers and AM broadcast stations with non-directive antennas are within 0.8 kilometers. The closest station to the Black Oak Wind Farm project, WHCU, is directive and located more than 5.3 kilometers from the project area of interest. Therefore, there should be no impact to the coverage of AM stations from the proposed wind farm. The coverage of FM stations is not subject to degradation when the stations are at distances greater than 4.0 kilometers from wind turbines. Three stations, WFIZ, W281AT, and WQNY, are currently operating within 500 meters of the project area of interest, less than the 4.0 kilometer recommended distance. The proposed turbines for the Black Oak Wind Farm will have a hub height of 92 meters and a blade diameter of up to 116 meters, giving the structures an overall maximum height of 150 meters above ground level and a minimum blade tip height of 34 meters. The antenna heights for WFIZ, W281AT, and WQNY are 45 meters, 39 meters and 42 meters, respectively. Therefore, all three of the stations have antenna heights that fall between the minimum blade tip height of 34 meters and the maximum overall height of 150 meters. This means that there is a strong potential for the stations’ coverage to be limited by the Black Oak Wind Farm turbines. 4. Recommendations Since no impact on the AM broadcast stations was identified in our database search, no recommendations or mitigation techniques are required for this project. For the FM stations, the analysis shows that three licensed stations are at risk of having their coverage affected. Enfield Energy may wish to discuss the issue with the stations’ management to determine methods to mitigate the coverage issue. Installation of auxiliary antennas to fill-in the lost coverage areas may also be a possible solution. Comsearch would be happy to assist Enfield Energy in assessing the lost coverage and proposing various mitigation techniques to restore station coverage once the wind turbine locations are defined.

Introduction Our communication signals assessment was performed for Enfield Energy to identify the land mobile and emergency services, mobile phone, cable and satellite and other wireless signals near the proposed wind farm project area that may be potentially be impacted by the wind project. This assessment is useful in the planning stages of the wind energy facilities to identify turbine setbacks and mitigation strategies if necessary. This data can also be used in support of the wind energy facility’s communications needs in addition to avoiding any potential impact to the current communications services provided in that region. This study was performed for the Black Oak Wind Farm in Tompkins County, New York. An overview of the project area appears below. Enfield Energy LLC Wind Power GeoPlanner™ Communication Signals Assessment Black Oak Wind Farm Comsearch Proprietary - 2 - December 29, 2011 2. Land Mobile and Emergency Services Assessment An assessment of the emergency services in the Black Oak Wind Farm project area was performed by Comsearch to identify potential impact from the planned turbines. We evaluated the registered frequencies for the following types of first responder entities: police, fire, emergency medical services, emergency management, hospitals, public works, transportation and other state, county, and municipal agencies. We also identified all industrial and business land mobile radio (LMR) systems and commercial E911 operators near the proposed wind energy facility. Our land mobile and emergency services incumbent data1 was derived from the FCC’s Universal Licensing System (ULS) and the FCC’s Public Safety & Homeland Security bureau. We identified both site-based licenses as well as regional area-wide licenses designated for public safety use. The site-based licenses were imported into GIS software and geographically mapped within the wind energy project area of interest as defined by the customer. Each site on the map was given an ID number and associated with site information provided in a data table. A depiction of the fixed-site licenses near the project area appears in Figure 1, below. 1 Comsearch makes no warranty as to the accuracy of the data included in this report beyond the date of the report.

Since mobile phone market boundaries differ from service to service, we disaggregated the carriers’ licensed areas down to the county level. We have identified the type of service for each carrier in Tompkins County in Table 3, below. Enfield Energy LLC Wind Power GeoPlanner™ Communication Signals Assessment Black Oak Wind Farm Comsearch Proprietary - 7 - December 29, 2011 Service2 Mobile Phone Carrier County State AWS / CELL / PCS AT&T Tompkins NY PCS Blue Wireless Tompkins NY AWS Metro PCS Tompkins NY AWS SpectrumCo Tompkins NY PCS Sprint Nextel Tompkins NY AWS / PCS T-Mobile Tompkins NY AWS / CELL / PCS Verizon Tompkins NY Table 3: Mobile Phone Carriers in the Area of Interest with E911 Service Analysis The first responder, industrial/business land mobile sites, area-wide public safety, and commercial E-911 communications as described in this report are typically unaffected by the presence of wind turbines and we do not anticipate any significant harmful effect to these services in the Black Oak Wind Farm project area. Although each of these services operates in different frequency ranges and provides different types of service including voice, video and data applications, there is commonality among these different networks in regards to the impact of wind turbines on their service. Each of these networks is designed to operate reliably in a non-line-of-sight (NLOS) environment. Many land mobile systems are designed with multiple base transmitter stations covering a large geographic area with overlap between adjacent transmitter sites in order to provide handoff between cells, and any signal blockage caused by the wind turbines does not materially degrade the reception because the end user is likely receiving signals from multiple transmitter locations. Additionally, the frequencies of operation for these services have characteristics that allow the signal to propagate through wind turbines. As a result, very little, if any, change in their coverage should occur when the wind turbines are installed. When planning the wind energy turbine locations in the area of interest, a conservative approach would dictate not locating any turbines within 77.5 meters of land mobile fixed-base stations to avoid any possible impact to the communications services provided by these stations. This distance is based on FCC interference emissions from electrical devices in the land mobile frequency bands. The closest land mobile site, KEB422, is 375 meters from the area of interest, which is a sufficient distance to avoid any impact. In the unlikely event that a public safety entity believes their coverage has been compromised by the presence of the wind energy facility, they have many options to improve their signal coverage to the area through optimization of a nearby base station or even adding a repeater 2 AWS: Advanced Wireless Service at 1.7/2.1 GHz CELL: Cellular Service at 800 MHz PCS: Personal Communication Service at 1.9 GHz Enfield Energy LLC Wind Power GeoPlanner™ Communication Signals Assessment Black Oak Wind Farm Comsearch Proprietary - 8 - December 29, 2011 site. Utility towers, meteorological towers or even the turbine towers within the wind project area can serve as the platform for a base station or repeater site. 3. Mobile Phone Assessment Mobile phone carriers operate in multiple frequency bands and are often referred to as Advanced Wireless Service (AWS), Personal Communication Service (PCS), and Cellular. They hold licenses on an area-wide basis which are typically comprised of several counties. Our mobile phone analysis was performed using Comsearch’s proprietary carrier database, which is derived from a variety of sources including the Federal Communications Commission (FCC). Since mobile phone market boundaries differ from service to service, we disaggregated the carriers’ licensed areas down to the county level. Then we compiled a list of all mobile phone carriers in the main counties that intersect the area of interest. The Black Oak Wind Farm is located in Tompkins County, New York. We have identified the type of service, channel block, market ID and FCC callsign for each carrier in the county of interest. A description of the various service types and geographic market areas is below with a summary table on the following page. AWS AWS licensees won their spectrum in an auction that started in August 2006. The licenses are authorized by 734 Cellular Market Areas (CMA) for Block A, 176 Economic Areas (BEA) for Blocks B and C, and 12 Regional Economic Area Groupings (REA) for Blocks D, E and F. This spectrum at 1.7 and 2.1 GHz was allocated for mobile broadband and advanced wireless services. Partitioning and leases are permitted in the band. Cellular Licensees are authorized by Metropolitan and Rural Statistical Areas, also known as CMAs. Unserved areas can be covered by licensees other than the original A or B block licensee. To determine the most realistic coverage, we compiled the Cellular Geographic Service Areas (CGSA) from the 32 dBu contours defined by Part 22.911(a) of the FCC rules. Mobile services are provided at 800 MHz and partitioning and leases are permitted in the band. PCS There have been nine auctions for this band, with the last one being held in August 2008. Licensees are authorized by 51 Major Trading Areas (MTA) for Blocks A and B, and 493 Basic Trading Areas (BTA) for Blocks C through F. This band has been heavily partitioned and disaggregated both by counties and by smaller polygons within counties (known as undefined areas or partial counties). The 1.9 GHz PCS carriers provide mobile services and leases are permitted in the band.

Since mobile telephone signals are designed with overlap between adjacent base transmitter sites in order to provide handoff between cells, any signal blockage caused by the wind turbines does not materially degrade the reception because the end user may be receiving from multiple transmitter locations. For example, if a particular turbine attenuates the signal reception into a mobile phone, the phone may receive an alternate signal from a different transmit location, resulting in no disruption in service. Mobile phone systems that are implemented in urban areas near large structures and buildings often have to combat even more problematic signal attenuation and reflection conditions than rural areas containing a wind energy turbine facility. Thus we do not anticipate any significant harmful effect to mobile phone services in the Black Oak Wind Farm project area.

Cable and Satellite Assessment This section provides an assessment of cable and satellite sites identified within or near the Black Oak Wind Farm. A headend facility is the core of a cable television (CATV) system. The facility handles many types of functions including reception and processing of broadcast or “off- air” television signals and reception, decryption and modulation of satellite programming for distribution to their cable TV subscribers. Wind turbines may affect cable headend facilities that are receiving wireless off-air television and satellite signals. In addition, wind turbines may attenuate the signal transmitted and received in satellite uplinks and receive earth stations. Our cable and satellite data is derived from a variety of sources including the FCC’s cable and international bureau databases, as well as the operators themselves. We identified the physical system IDs (PSIDs), community units and cable operators in the area of interest. In general, each unique PSID corresponds to a principal headend facility with multiple community units served by that facility, also referred to as a cable plant. A summary of the cable systems near the area of interest appears in the table below.

The data was imported into GIS software and the structures mapped in relation to the wind energy area of interest (see Figure 1). Each cable or satellite site on the map is identified with an ID number associated with site information provided in Table 6. 3 Cable headend locations are derived from the cable provider’s office locations and the FCC’s aeronautical notification form for cable systems. These locations should be verified with the local cable office. 4 Earth station locations are known if they provide non-temporary services. VSAT terminals, DBS dishes (DirecTV and DISH, e.g) and other receive-only earth stations are not required to be licensed with the FCC.

Since all of the cable and satellite sites identified near the Black Oak Wind Farm are well outside the area of interest, no impact to their services is expected. 5. Conclusions Based on the land mobile, emergency services, mobile phone, and cable and satellite services located near the Black Oak Wind Farm, the planned turbines will not have any impact on these types of communication signals. The closest land mobile site, KEB422, is 375 meters from the project area and beyond the recommended setback distance based on interference emissions from electrical devices. Since mobile telephone signals are designed with overlap between adjacent base transmitter sites in order to provide handoff between cells, any signal blockage caused by the wind turbines does not materially degrade the reception because the end user may be receiving from multiple transmitter locations. Lastly, the cable and satellite services in the area should not be affected because no head end facilities or receive earth stations are near the project area.

Introduction Our government radar analysis was performed to determine if there would be any significant degradation to the operational coverage of government radar operations located near the Black Oak Wind Farm project in Tompkins County, New York. Figure 1 shows the location of the wind energy project in New York. There are three types of radars that Comsearch examined as part of this analysis; DoD military systems, the weather service system’s NEXRAD (WSR-88D) and the FAA Long Range radar systems. Figure 1: Location of Black Oak Wind Farm Project in the State of New York Enfield Energy LLC Wind Power GeoPlanner™ Government Radar System Analysis Report Black Oak Wind Farm Comsearch Proprietary - 2 - December 29, 2011 2. Summary of Results Comsearch used the Department of Defense (DoD) radar screening tool to examine whether potential coverage issues were anticipated for these radar systems1. Both the center point and corner coordinates of the project area of interest (AOI) were used as an input parameter for the screening tool. The results from the DoD screening tool indicated that there are no potential issues for operational military systems or FAA long range radar systems, but potential issues were found in regards to the weather service NEXRAD radar system in Binghamton, NY. In support of these findings three figures were taken from the DoD screening tool and are presented in Appendix A of this report. Figure A1 shows the results of the military system screening. The map shows that there are no military facilities in the area and the screening tool stated no issues with military systems are anticipated with the planned location of the Black Oak Wind Farm project. Thus the review does not return any likely impacts to military airspace. We recommend that you contact the following persons for confirmation and documentation of this finding: • David Brentzel with the USAF Regional Environmental Coordinator, at (404) 562-4211 • US Navy Representative, FAA Eastern Service Area, with the USN Regional Environmental Coordinator at (404) 305-6908 • LTC Jeffrey Martuscelli with the USA Regional Environmental Coordinator at (404) 305- 6915 • US Marine Corps Representative, FAA Eastern Service Area, with the USMC Regional Environmental Coordinator at (404) 305-6907 Figure A2 shows the results of the weather service NEXRAD radar systems screening. The map shows that the project area will be located in the ‘Dark Green’ coverage zone 37.8 miles from the Binghamton radar site. The ‘Dark Green’ designation means that some impact is possible. Consultation with NOAA (weather service) is optional. However, we recommend that Enfield Energy notify the NTIA of the proposed project to confirm these results. The NTIA will coordinate directly with the weather service to obtain the determination. If the weather service does have a concern, they would typically work with Enfield Energy to mitigate this obstruction. This may include consulting with Enfield Energy in the selection of wind turbine locations to further minimize the impact on the NEXRAD radar coverage. Figure A3 shows the results of the FAA Long Range radar systems screening. The screening tool shows three FAA long range radar systems in the area. However, these radar systems are located far enough away from the project where no impact on its coverage is anticipated. Table 1 lists the FAA radar locations and their approximate distance from the center of the Black Oak Wind Farm project site. They range from approximately 70 to 120 kilometers away. At these distances the signal beam from the radar will pass well above the tip heights of the wind turbines planned for this project. 1 Comsearch makes no warranty as to the accuracy of the data included in this report beyond the date of the report.

Enfield Energy LLC Wind Power GeoPlanner™ Government Radar System Analysis Report Black Oak Wind Farm Comsearch Proprietary - 3 - December 29, 2011 FAA Radar Location Distance to Center of Project (km) Northwest of Project 71.0 Northeast of Project 120.0 South of Project 78.2 Table 1: Distances of FAA Long Range Radar to Center of Black Oak Wind Farm Project 3. Analysis The location of the Black Oak Wind Farm project is shown in Figure 1. The proposed turbines will have a hub height of 92 meters and a blade diameter of up to 116 meters, giving the structures an overall maximum height of 150 meters above ground level. The wind turbine locations for the Black Oak project have not yet been finalized. The screening tool revealed that the location of the Black Oak Wind Farm project is a sufficient distance away from DoD military systems and FAA Long Range radar systems. The screening tool did identify a potential impact with the Binghamton NEXRAD radar site used by the weather service. The radar system is located 37.8 miles from the project area. The tool showed only a possible minor impact to that system. Further evaluation and consultation with NOAA is recommended. This consultation should be initiated through the NTIA who will coordinate with federal government agencies including NOAA to evaluate the proposed Black Oak Wind Farm project. 4. Conclusions and Recommendations No military RADAR coverage or operational issues have been identified for the Black Oak Wind Farm. We recommend contacting the persons listed in Section 2 for confirmation and documentation of their findings. Once the locations of the wind turbines are defined, we also recommend sending those locations to the DoD Energy Siting Clearinghouse for final approval on military issues. There are no issues with the three FAA Long Range RADAR systems listed in Table 1 since the separation distances are far enough to eliminate potential obstruction to the RADAR signals. There is a potential issue with the weather service that may require coordination with NOAA through the NTIA. We expect that the coordination with the weather service will address and resolve any issue. .
