For this report, EBI utilized antenna and power data provided by AT&T and compared the resultant worst- case MPE levels to the FCC’s occupational/controlled exposure limits outlined in OET Bulletin 65. The assumptions used in the modeling are based upon information provided by AT&T and information gathered from other sources. A power reduction factor of 0.32 of maximum power was applied to account for spatial distribution of served users, as recommended by AT&T and its antenna system manufacturers. Unknown carriers also have antennas on the transmission tower. Information about these antennas was included in the modeling analysis. Based on worst-case predictive modeling, there are no modeled exposures on any accessible utility line level and ground walking/working surface related to ATT’s proposed antennas that exceed the FCC’s occupational and/or general public exposure limits at this site. At the nearest walking/working surfaces to the AT&T antennas on the utility line level, the maximum power density generated by the AT&T antennas is approximately 5.95 percent of the FCC’s general public limit (1.19 percent of the FCC’s occupational limit). The composite exposure level from all carriers on this site is approximately 6.67 percent of the FCC’s general public limit (1.33 percent of the FCC’s occupational limit) at the nearest walking/working surface to each antenna. It should be noted that percentage of MPE is based on spatially-averaged power densities over a height of six feet, with the height of the utility line being centered within that spatial range. Based on worst-case predictive modeling, there are no areas at ground/street level related to the proposed AT&T antennas that exceed the FCC’s occupational or general public exposure limits at this site. At ground/street level, the maximum power density generated by the antennas is approximately 10.6 percent of the FCC’s general public limit (2.12 percent of the FCC’s occupational limit). There are no modeled areas on the utility line level and ground that exceed the FCC’s limits for general public or occupational exposure in front of the other carrier antennas. Microwave dish antennas are designed for point-to-point operations at the elevations of the installed equipment rather than ground-level coverage. Based on AT&T’s RF Exposure: Responsibilities, Procedures & Guidelines document, dated October 28, 2014, microwave antennas are considered compliant if they are higher than 20 feet above any accessible walking/working surface. There are no microwaves installed at this site. AT&T Proprietary (Internal use only).

Site Name: Blackberry Farm Golf Course Site USID: 47259 Site FA: 10100806 18 Appendix A:F EDERAL C OMMUNICATIONS C OMMISSION (FCC)R EQUIREMENTS The FCC has established Maximum Permissible Exposure (MPE) limits for human exposure to Radiofrequency Electromagnetic (RF-EME) energy fields, based on exposure limits recommended by the National Council on Radiation Protection and Measurements (NCRP) and, over a wide range of frequencies, the exposure limits developed by the Institute of Electrical and Electronics Engineers, Inc. (IEEE) and adopted by the American National Standards Institute (ANSI) to replace the 1982 ANSI guidelines. Limits for localized absorption are based on recommendations of both ANSI/IEEE and NCRP. The FCC guidelines incorporate two separate tiers of exposure limits that are based upon occupational/controlled exposure limits (for workers) and general public/uncontrolled exposure limits for members of the general public. Occupational/controlled exposure limits apply to situations in which persons are exposed as a consequence of their employment and in which those persons who are exposed have been made fully aware of the potential for exposure and can exercise control over their exposure. Occupational/ controlled exposure limits also apply where exposure is of a transient nature as a result of incidental passage through a location where exposure levels may be above general public/uncontrolled limits (see below), as long as the exposed person has been made fully aware of the potential for exposure and can exercise control over his or her exposure by leaving the area or by some other appropriate means. General public/uncontrolled exposure limits apply to situations in which the general public may be exposed or in which persons who are exposed as a consequence of their employment may not be made fully aware of the potential for exposure or cannot exercise control over their exposure. Therefore, members of the general public would always be considered under this category when exposure is not employment-related, for example, in the case of a telecommunications tower that exposes persons in a nearby residential area. Table 1 and Figure 1 (below), which are included within the FCC’s OET Bulletin 65, summarize the MPE limits for RF emissions. These limits are designed to provide a substantial margin of safety. They vary by frequency to take into account the different types of equipment that may be in operation at a particular facility and are “time-averaged” limits to reflect different durations resulting from controlled and uncontrolled exposures. 2 The FCC’s MPEs are measured in terms of power (mW) over a unit surface area (cm). Known as the power density, the FCC has established an occupational MPE of 5 milliwatts per square centimeter 2 2 for equipment operating in the 1900 MHz frequency (mW/cm) and an uncontrolled MPE of 1 mW/cm 2 range . For the AT&T equipment operating at 700 MHz, the FCC’s occupational MPE limit is 2.33 mW/cm 2 . For the AT&T equipment operating at 1900 MHz, the and an uncontrolled MPE limit of 0.47 mW/cm 22 FCC’s occupational MPE is 5.0 mW/cm and an uncontrolled MPE limit of 1.0 mW/cm. These limits are considered protective of these populations. AT&T Proprietary (Internal use only).

These limits apply for continuous exposures and are intended to provide a prudent margin of safety for all persons, regardless of age, gender, size, or health. Personal Communication (PCS) facilities used by AT&T in this area operate within a frequency range of 700-1900 MHz. Facilities typically consist of: 1) electronic transceivers (the radios or cabinets) connected to wired telephone lines; and 2) antennas that send the wireless signals created by the transceivers to be received by individual subscriber units (PCS telephones). Transceivers are typically connected to antennas by coaxial cables. Because of the short wavelength of PCS services, the antennas require line-of-site paths for good propagation, and are typically installed above ground level. Antennas are constructed to concentrate energy towards the horizon, with as little energy as possible scattered towards the ground or the sky. This design, combined with the low power of PCS facilities, generally results in no possibility for exposure to approach Maximum Permissible Exposure (MPE) levels, with the exception of areas directly in front of the antennas. FCC Compliance Requirement A site is considered out of compliance with FCC regulations if there are areas that exceed the FCC exposure limits and there are no RF hazard mitigation measures in place. Any carrier which has an installation that contributes more than 5% of the applicable MPE must participate in mitigating these RF hazards. AT&T Proprietary (Internal use only).

Site Name: Blackberry Farm Golf Course Site USID: 47259 Site FA: 10100806 23 Appendix D:L IMITATIONS This report was prepared for the use of AT&T Mobility, LLC to meet requirements outlined in AT&T’s corporate RF safety guidelines. It was performed in accordance with generally accepted practices of the trade, albeit proprietary in specific content, including other consultants undertaking similar studies at the same time and in the same locale under like circumstances. The conclusions provided by EBI and its partners are based solely on information supplied by AT&T, including modeling instructions, inputs, parameters and methods. Calculations, data, and modeling methodologies for C Band equipment Include a statistical factor reducing the power to 32% of maximum theoretical power to account for spatial distribution of users, network utilization, time division duplexing, and scheduling time. AT&T recommends the use of this factor based on a combination of guidance from its antenna system manufacturers, supporting international industry standards, industry publications, and its extensive experience. The observations in this report are valid on the date of the investigation. Any additional information that becomes available concerning the site should be provided to EBI so that our conclusions may be revised and modified, if necessary. This report has been prepared in accordance with Standard Conditions for Engagement and authorized proposal, both of which are integral parts of this report.

Site Name: Blackberry Farm Golf Course Site USID: 47259 Site FA: 10100806 24 Appendix E:RoofMaster™ RoofMaster™ is a widely-used predictive modeling program that has been developed to predict RF power density values for rooftop and tower telecommunications sites produced by vertical collinear antennas that are typically used in the cellular, PCS, paging and other communications services. Using the computational methods set forth in Federal Communications (FCC) Office of Engineering & Technology (OET) Bulletin 65, “Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields” (OET-65), RoofMaster™ calculates predicted power density in a scalable grid based on the contributions of all RF sources characterized in the study scenario. At each grid location, the cumulative power density is expressed as a percentage of the FCC limits. Manufacturer antenna pattern data is utilized in these calculations. RoofMaster™ models consist of the Far Field model as specified in OET-65 and an implementation of the OET-65 Cylindrical Model (Sula9). The models utilize several operational specifications for different types of antennas to produce a plot of spatially-averaged power densities that can be expressed as a percentage of the applicable exposure limit. A power reduction factor of 0.32 of maximum power was applied to account for spatial distribution of served users, as recommended by AT&T. AT&T Proprietary (Internal use only).
