RF-EME Compliance Report USID No. 12998 Site No. CCL04368 EB1 Project No. 62120600 95 Bliss Avenue, Pittsburg, California EXECUTIVE SUMMARY Purpose of Report EnviroBusiness Inc. (dba EBI Consulting) has been contracted by AT&T Mobility, LLC to conduct radio frequency electromagnetic (RF-EME) modeling for AT&T Site CCL04368 located at 95 Bliss Avenue in Pittsburg, California to determine RF-EME exposure levels from proposed AT&T wireless communications equipment at this site. As described in greater detail in Section 2.0 of this report, the Federal Communications Commission (FCC) has developed Maximum Permissible Exposure (MPE) Limits for general public exposures and occupational exposures. This report summarizes the results of RF-EME modeling in relation to relevant FCC RF-EME compliance standards for limiting human exposure to RF-EME fields. This report contains a detailed summary of the RF EME analysis for the site, including the following: Antenna Inventory Site Plan with antenna locations Antenna inventory with relevant parameters for theoretical modeling Graphical representation of theoretical MPE fields based on modeling Graphical representation of recommended signage and/or barriers This document addresses the compliance of AT&T's transmitting facilities independently and in relation to all collocated facilities at the site. Statement of Compliance 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. As presented in the sections below, based on worst-case predictive modeling, there are no modeled areas on any accessible ground-level walking/working surface related to the proposed antennas that exceed the FCC's occupational or general public exposure limits at this site. AT&T Recommended Signage/Compliance Plan AT&T's RF Exposure: Responsibilities, Procedures & Guidelines document, dated December 9, 2011, requires that: I. All sites must be analyzed for RF exposure compliance; 2. All sites must have that analysis documented; and 3. All sites must have any necessary signage and barriers installed. Site compliance recommendations have been developed based upon protocols presented in AT&T's RF Exposure guidance document, dated December 9, 2011, additional guidance provided by AT&T, EB1's understanding of FCC and OSHA requirements, and common industry practice. Barrier locations have been identified (when required) based on guidance presented in AT&T's RF Exposure Policy guidance document, dated December 9, 2011. The following signage is recommended at this site: 14EBI

RF-EME Compliance Report US1D No. 12998 Site No. CCL04368 EBI Project No. 62120600 95 Bliss Avenue, Pittsburg, California SITE DESCRIPTION This project involves the proposed installation of three (3) LTE antennas in addition to the existing twelve (12) wireless telecommunication antennas on a monopole in Pittsburg, California. There are four Sectors (A, B, C, and D) proposed at the site, with four (4) antennas in Sectors A, B, and C and three (3) antennas in sector D. For modeling purposes, it is assumed that there will be one (I) UMTS antenna in each sector transmitting in two bands of the 850 and two bands of the 1900 MHz frequency ranges, one (I) UMTS antenna in each sector transmitting in the 1900 MHz frequency range, one (1) GSM antenna in each sector transmitting in the 850 and 1900 MHz frequency ranges, and one (I) LTE antenna in sectors A, B, and C transmitting in the 700 and 2100 MHz frequency ranges. The Sector A antennas will be oriented 20 (LTE) and 70 (GSM and UMTS) from true north. The Sector B antennas will be oriented 290 (GSM and UMTS) and 250 (LTE) from true north. The Sector C antennas will be oriented 110 (GSM and UMTS) and 125 (LTE) from true north. The Sector D antennas will be oriented 205 from true north.the bottoms of the antennas will be 72.9 feet above ground level. Appendix B presents an antenna inventory for the site. Access to this site is accomplished via a gate in the fence surrounding the tower. Workers must be elevated to antenna level to access them, so these antennas are not accessible to the general public. 1.0 FEDERAL COMMUNICATIONS COMMISSION (FCC) REQUIREMENTS 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

RF-EME Compliance Report EBI Project No. 62120600 USID No. 12998 Site No. CCL04368 95 Bliss Avenue, Pittsburg, California facility and are "time-averaged" limits to reflect different durations resulting from controlled and uncontrolled exposures. The FCC's MPEs are measured in terms of power (mvv) over a unit surface area (cm 2). Known as the power density, the FCC has established an occupational MPE of 5 milliwatts per square centimeter (mw/cm 2) and an uncontrolled MPE of 1 mw/cm2 for equipment operating in the 1900 MHz frequency range. For the AT&T equipment operating at 850 MHz, the FCC's occupational MPE is 2.83 mw/cm 2 and an uncontrolled MPE of 0.57 mw/cm 2. For the AT&T equipment operating at 700 MHz, the FCC's occupational MPE is 2.33 mw/cm 2 and an uncontrolled MPE of 0.47 mw/cm 2. These limits are considered protective of these populations.

RF-EME Compliance Report USID No. 12998 Site No. CCL04368 EB1 Project No. 62120600 95 Bliss Avenue, Pittsburg, California Based on the above, the most restrictive thresholds for exposures of unlimited duration to RF energy for several personal wireless services are summarized below: Personal Wireless Service Approximate Occupational Frequency MPE Public MPE Personal Communication (PCS) 1,950 MHz 5.00 mw/cm 2 1.00 mw/cm 2 Cellular Telephone 870 MHz 2.90 mw/cm 2 0.58 mw/cm 2 Specialized Mobile Radio 855 MHz 2.85 mw/cm 2 0.57 mw/cm 2 Most Restrictive Freq, Range 30-300 MHz 1.00 mw/cm 2 0.20 mw/cm2 MPE limits are designed to provide a substantial margin of safety. 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: I) 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. 2.0 AT&T RF EXPOSURE POLICY REQUIREMENTS AT&T's RF Exposure: Responsibilities, Procedures & Guidelines document, dated December 9, 2011, requires that: I. All sites must be analyzed for RF exposure compliance; 2. All sites must have that analysis documented; and 3. All sites must have any necessary signage and barriers installed. Pursuant to this guidance, worst-case predictive modeling was performed for the site. This modeling is described below in Section 4.0. Lastly, based on the modeling and survey data, EBI has produced a Compliance Plan for this site that outlines the recommended signage and barriers. The recommended Compliance Plan for this site is described in Section 5.0. 3.0 WORST-CASE PREDICTIVE MODELING In accordance with AT&T's RF Exposure policy, EBI performed theoretical modeling using RoofView software to estimate the worst-case power density at the site ground-level resulting from operation of the antennas. RoofView is a widely-used predictive modeling program that has been developed by Richard Tell Associates to predict both near field and far field RF power density values for roof-top and tower telecommunications sites produced by vertical collinear antennas that are typically used in the cellular, PCS, paging and other communications services. 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.

RF-EME Compliance Report USID No. 12998 Site No. CCL04368 EBI Project No. 62120600 95 Bliss Avenue, Pittsburg, California 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. Three unknown carriers also have antennas on the monopole. Information about these antennas was included in the modeling analysis. Based on worst-case predictive modeling, there are no modeled areas on any accessible ground-level walking/working surface related to the proposed AT&T antennas that exceed the FCC's occupational or general public exposure limits at this site. At the nearest walking/working surfaces to the AT&T antennas, the maximum power density generated by the AT&T antennas is approximately 6.80 percent of the FCC's general public limit (1.36 percent of the FCC's occupational limit). The composite exposure level from all carriers on this site is approximately 9.90 percent of the FCC's general public limit (1.98 percent of the FCC's occupational limit) at the nearest walking/working surface to each antenna. There are no modeled areas on the ground that exceed the FCC's limits for general public or occupational exposure in front of the other carrier antennas. The inputs used in the modeling are summarized in the RoofView export file presented in Appendix C. A graphical representation of the RoofView modeling results is presented in Appendix D. It should be noted that RoofView is not suitable for modeling microwave dish antennas; however, these units are designed for point-to-point operations at the elevations of the installed equipment rather than groundlevel coverage. Based on AT&T's RF Exposure: Responsibilities, Procedures & Guidelines document, dated December 9, 2011, 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. 21 B Street* Burlington, MA 01803 1.800.786.2346
