The purpose of these measurements was to identify and document Off-Air Television (TV) reception (TV channels). These measurements establish baseline conditions for the reception of each Off-Air TV channel by determining each TV channels signal strength reception level and evaluating the video and audio quality at each selected site. The purpose of this report is to document the results of these measurements. The analysis in this report is based upon the following: • • • • • Video Quality Rating Code of Federal Regulations Title 47, Part 73, Section 73.685 (Attachment 1) Television channels Type of Reception: Analog and Digital Measured Centerline: The test antenna was mounted 15 feet above ground level 1.2 Background Comsearch was contracted by Tetra Tech EC, Inc. of Morris Hills, New Jersey to establish the baseline conditions of Off-Air TV reception in the study area. Ten locations were selected to provide a broad coverage of the study area. Test site locations are shown in Figure 1.2-1. To determine which areas to be measured, Comsearch performed an analysis using the FCC and its own database to determine the TV broadcasters in the area surrounding the Alabama Ledge Wind Farm Project. The identified areas, which could potentially be affected by the construction of their proposed wind turbines that could cause propagation obstruction, ghosting and multipathing, are identified in Figure 1.2-1. After the wind energy facility is built measurements can be made at all sites where signal blockage, multipathing, ghosting and/or electromagnetic noise is reported and/or suspected. Theses measurements will be compared to the baseline measurements reported here to determine whether the degraded affects are the result of the presence of the wind turbines. If the measurements and analysis verify signal blockage, multipathing, ghosting and/or electromagnetic noise due to the wind turbines, Comsearch can provide consulting services to Tetra Tech EC, Inc. of Morris Hills, NJ to mitigate the conditions. 1.3 Constraints The analysis in this report is based upon the following assumptions and constraints. • The test antenna gains are based on the information supplied by Wineguard for their RV 2000 VHF/UHF antenna. • It is assumed that during the measurement period all of the TV broadcast transmitters were active and operating at full transmit power for the licensed frequencies unless otherwise noted. • The signal identification and channels analyzed are based upon information obtained from CEA Antenna Web Selector Site. • All azimuths are in degrees true north. • The Video Quality was rated using the following criteria: Analog Video Quality Criteria 1 Cable Quality- Perfect. 2 Some noise but excellent picture. 3 Good quality, but noticeable sparkles. Good but not excellent. 4 Fair quality, noticeable noise, sparkles, and distortion. 5 Intermittent video. Not viewable, unacceptable. 6 No detected video. Digital Video Quality Criteria 1 Cable Quality – Perfect 2 Some video blocking/freezing occurring 3 No video detected Topo USA® 5.0 Data use subject to license. © 2004 DeLorme.

All test equipment used was allowed a proper warm-up period prior to calibration. The test set was calibrated by the signal substitution method, utilizing the Signal generator output from the HP86630L. The calibrated reference at (zero dBm) from the signal generator injected into the end of the coaxial cable of the test set at the point that normally connects to the test antenna. An HP E4407B spectrum analyzer then measures the reference signal level after passing through the test set. At this point, the HP E4407B spectrum analyzer is calibrated such that the displayed signal on the spectrum analyzer displays the losses of the testing system at each individual frequency. Upon completion of the calibration process, a known reference level is obtained for the measurements that correspond to a given set of spectrum analyzer readings. The following formula is used to transform the measured signal level as initially viewed on the spectrum analyzer display (dBm) as seen at the point and time of testing to an isotropic reference signal level (dBmI) as adjusted by the Dell computer software program in the output display of the spectrum photographs. Where: dBmI = LI - GA dBmI = Isotropic level in dBm LI = Level (dBm) of injected signal GA = Test antenna gain For TV channels 2 to 13: dBmI = 0 dBm – 15.5 dB = -15.5 dBmI For TV channels 14 to 69: dBmI = 0 dBm – 19.5 dB = -19.5 dBmI Therefore, the proper gain needs to be applied dependent on the TV broadcast channel measured. The gains have been applied to each spectrum photograph included in this report. Figures 2.1-2 (A) (B) (C) display the spectrum photographs of the described calibration procedures employed during the TV broadcast measurements. 2.2 Methodology Upon arriving at the measurement site, coordinates were obtained using GPS instrumentation. Photographs were taken to document the site and are included in this report. After site coordinates were verified, the test equipment was set up to measure the RF environment. Measurements were conducted at 10 locations in the vicinity of the wind farm. After the equipment set up was completed, the test antenna was mounted on an extendable tower and elevated to a height of 12 feet above the ground level. The antenna was rotated 360 degrees (scanning) while in the horizontal plane while monitoring the TV monitor and spectrum analyzer. The test antenna was peaked on each channel of interest and the azimuth, signal level and the video quality rating was recorded and included in this report (Tables 4.1-1 through 4.13-1, Video Quality). Video recording of each TV channel was performed for a 30 second period. These video recordings will be retained with Comsearch. Upon completion of the RF testing, the measured signal levels were transposed from dBm to dBuV/m after accounting for the gain of the test antenna, and the bandwidth factor of the spectrum analyzer. The following is a description on how the conversion of the data from dBm to dBuV/m (dB above one µV/m) was accomplished. The data was converted to dBuV/m to compare it with the minimum field strength levels outlined in FCC 47CFR73.685 (a). Below is set of two formulas that were used to convert the measured signals in dBm to field strength measurements in dBuV/m. First the isotropic receive level in dBm was converted to field strength in V/m using the formula below: E = (480 * π2 * Pm / λ2)1/2 Where: λ = the wavelength (= c/f) c = speed of light f = frequency in Hz Pm = Power measured in Watts Watts = (10^ ( PdBm /10))/1000 PdBm = Power in dBm E = Field Strength in V/m Last the field strength in V/m was converted to field strength in dBuV/m (dB above 1µV/m) using the formula below: E dB = 20 log (E * 1x106) Where: E = Field Strength in V/m EdB = Field Strength in dBuV/m 1x106 = is the conversion factor used to covert from V/m to µV/m WINEGARD RV2000 ACTIVE VHF/UHF ANTENNA HP 86630L Signal Generator Calibration Signal TV/VCR COMBO HP 437B Power Meter HP EPM SERIES Power Meter HP E4407B Spectrum Analyzer HD TUNER Figure 2.1-1 Test Equipment Block Diagram DELL Laptop Computer Alabama, New York Tetra Tech EC, Incorporated Date: 12/03/2006 Center Freq: 71 MHz Span: 100 MHz Res.

The overall area is a mixture of forest and farmland with average elevations of 650-850 feet AMSL. Cable Television is available in all the communities tested. Off-air reception was generally limited to a minimum of eleven channels to a maximum of twenty channels. The primary transmitters are from Buffalo and Rochester, New York. The Canadian Broadcasters are not an issue as the channels received were in excess of 65 miles. The four major networks (ABC, NBC, CBS and FOX) are represented. All other channels are Independents and or City controlled low power transmitters. There are a few translators in use and can be a compounding factor in determining a correct channel count. Off-air antennas were visible on approximately 5% of the residences and 5% were utilizing satellite systems. See Section 3 for the Site and Spectrum Photographs.

The area is made up of rolling hills with a mixture of forest, farmland and areas used for recreational purposes. The average elevation is 650 - 850 feet AMSL. The Ten sites selected provide a broad coverage area around the Wind Energy Facility. The immediate communities surrounding the Wind Turbine Facility have small population densities and most of the communities contain less than 1000 people. Several conclusions about the area, around and in, the proposed Wind Energy Facility with respect to off-air TV reception are as follows. • Cable television has penetrated the entire area. The cable television programming provided is considered very good. • The majority of the off-air transmitters are located in the Buffalo and Rochester, NY areas. The other off-air TV transmitters that service the area are either low power or translators or at distances greater than 65 miles. • Off-air antennas were installed on about five percent of the homes, as were direct broadcast satellite antennas. One observation noted about the off-air TV antennas in use was that the majority of them were aligned in azimuth toward Buffalo, NY. The off-air antennas in use appear to be installed below the tree line and in need of repair. Programming from the four major networks (ABC, CBS, NBC, and FOX) was available at all test sites. The Canadian Broadcasters are not available to a quality suitable for viewing in most locations. The measurement sites, on average, received eleven to eighteen analog stations and one to nine digital stations. • The placement of the turbines inside the area of interest should produce very little affect to off-air reception in the communities to the North and South. Communities to the East may experience some issues receiving all of the channels they now receive. • The community of Wheatville Station is the closest community to the center of the AOI and this is the community that received the greatest number of analog and digital off-air TV stations that were suitable for viewing. This community may be an area that will require mitigation for degraded TV reception. One cautionary note about this community is that it was the only area that had signs saying “No to Wind Power.” Typically, a recommended solution for off-air TV reception issues caused by wind turbines is to advocate the use of cable television. In Genesee County area, this solution appears to be practical for almost all locations that may be affected because Cable Television is available in most areas excluding the more rural areas. For the remote and sparsely populated areas that may be affected, satellite television systems would be the recommended choice given the topography and separation distance between homes of the rural areas. Satellite television reception is unaffected by the presence of wind turbines or hilly topography. ATTACHMENTS ATTACHMENT 1 CITE: 47CFR73.685 [Page 222-224] TITLE 47--TELECOMMUNICATION PART 73--RADIO BROADCAST SERVICES--Table of Contents Subpart E--Television Broadcast Stations Sec. 73.685 Transmitter location and antenna system. (a) The transmitter location shall be chosen so that, on the basis of the effective radiated power and antenna height above average terrain employed, the following minimum field strength in dB above one uV/m will be provided over the entire principal community to be served: -----------------------------------------------------------------------Channels 2-6 Channels 7-13 Channels 14-69 -----------------------------------------------------------------------74 dBu 77 dBu 80 dBu -----------------------------------------------------------------------(b) Location of the antenna at a point of high elevation is necessary to reduce to a minimum the shadow effect on propagation due to hills and buildings which may reduce materially the strength of the station's signals. In general, the transmitting antenna of a station should be located at the most central point at the highest elevation available. To provide the best degree of service to an area, it is usually preferable to use a high antenna rather than a low antenna with increased transmitter power. The location should be so chosen that line-ofsight can be obtained from the antenna over the principal community to be served; in no event should there be a major obstruction in this path. The antenna must be constructed so that it is as clear as possible of surrounding buildings or objects that would cause shadow problems. It is recognized that topography, shape of the desired service area, and population distribution may make the choice of a transmitter location difficult. In such cases, consideration may be given to the use of a directional antenna system, although it is generally preferable to choose a site where a nondirectional antenna may be employed. (c) In cases of questionable antenna locations it is desirable to conduct propagation tests to indicate the field strength expected in the principal community to be served and in other areas, particularly where severe shadow problems may be expected. In considering applications proposing the use of such locations, the Commission may require site tests to be made. Such tests should be made in accordance with the measurement procedure in Sec. 73.686, and full data thereon must be supplied to the Commission. Test transmitters should employ an antenna having a height as close as possible to the proposed antenna height, using a balloon or other support if necessary and feasible. Information concerning the authorization of site tests may be obtained from the Commission upon request. (d) Present information is not sufficiently complete to establish ``blanket areas'' of television broadcast stations. A ``blanket area'' is that area adjacent to a transmitter in which the reception of other stations is subject to interference due to the strong signal from this station. The authorization of station construction in areas where blanketing is found to be excessive will be on the basis that the applicant will assume full responsibility for the adjustment of reasonable complaints arising from excessively strong signals of the applicant's station or take other corrective action.
