Executive Summary
Purpose of Report
EnviroBusiness Inc. (dba EBI Consulting) has been contracted by Verizon Wireless to conduct radio
frequency electromagnetic (RF-EME) modeling for Verizon Wireless site Feather Falls Casino,
located at Ophir Road, Oroville, CA 95966to determine RF-EME exposure levels from proposed
telecommunications equipment at this site. As described in greater detail in Appendix C – Federal
Communications Commission (FCC) Requirements of this report, the FCC has developed Maximum
Permissible Exposure (MPE) Limits for the general population and for occupational activities. The
FCC requires wireless system operators to perform an assessment of potential human exposure to
RF fields emanating from all transmitting antennas at a site whenever antenna operations are added
or modified, and to ensure compliance with the MPE limit in the FCC regulations. This report
summarizes the results of RF-EME modeling in relation to relevant FCC RF-EME
regulations/compliance standards
This report describes modeling calculations of RF levels associated with the existing and proposed
antennas. We have performed 3-dimensional modeling calculations to account for the effects of the
antennas at all roof level(s) and at street level employing standard FCC mathematical models for
calculating the effects of the antennas in a conservative manner. Therefore, our results provide
worst-case RF levels to ensure the conclusions are conservative with regard to compliance with the
FCC limit for safe continuous exposure.
Statement of Compliance
There are no other existing antenna carriers at the site to include in the compliance assessment.
Note that FCC regulations require any future antenna collocators to assess and assure continuing
compliance based on the cumulative effects of all then-proposed and then-existing antennas at the
Site. As presented in the sections below, our conclusions are based on worst-case modeling
calculations related to the existing and proposed antennas.
At ground level, the maximum cumulative exposure level from Verizon Wireless at this Site is
approximately 4.753 percent of the FCC’s general population limit (0.9506 percent of the FCC’s
occupational limit).
Workers climbing the Monopine should be informed about the presence and locations of antennas
and their associated fields. Due to the use of such conservative calculations for purposes of our
analysis, it should be noted that the exposure levels actually caused by the antennas will likely be
less significant than the calculated results herein.
As the site is in compliance with applicable FCC limits as designed, there are no additional control
measures required (See Section 3). Notwithstanding, it is also recommended that in connection with
a lockout/tagout procedure, any non-Verizon Wireless worker/contractor who will be working on

sufficient information was available to model them. Note that EBI uses an assumed set of antenna
specifications and powers for unknown and other carrier antennas for modeling purposes. The FCC
guidelines incorporate two separate tiers of exposure limits that are based upon
occupational/controlled exposure limits (for workers) and general population/uncontrolled
exposure limits for members of the general public that may be exposed to antenna fields. While
access to this site is considered controlled, the analysis has considered exposures with respect to
both controlled and uncontrolled limits as an untrained worker may access adjacent rooftop
locations. Additional information regarding controlled/uncontrolled exposure limits is provided in
Appendix C. Appendix B presents a site safety plan that provides a plan view of the Monopine with
antenna locations.

2. Worst-Case Predictive Modeling
This section provides details of the installation that the compliance assessment is performed for.
Information about the compliance calculation software utilized, predicted emission results and
antenna safety setbacks are included.
Compliance Simulation Software
The IXUS electromagnetic field (EMF) calculation software was used to assess all the RF field levels
presented in this study. IXUS (https://ixusapp.com/) is a software product of Alphawave Mobile
Network Products (Pty) Ltd, who specialize in electromagnetic software and systems. The IXUS
software uses a fast and accurate EMF calculation tool that allows for the determination of RF field
strength in the vicinity of radio communication base stations and transmitters. At its core, the IXUS
EMF calculation module implements field evaluation techniques detailed in the ITU-T K.61,
CENELEC 50383, and IEC62232 specifications. The calculation of EMF results at any point in 3-D
space is achieved by either a synthetic ray tracing technique, a conservative cylindrical envelope
method, or through full-wave EM simulation results obtained from a computational electromagnetic
software tool.
The selection of the solution method is determined by the specific antenna being considered. In
addition, a conservative and verified modelling technique for 5G beamforming antennas in IXUS is
used. The simulation accuracy of the IXUS calculation module has been verified extensively with full-
wave EM simulations.
IXUS Version Number: 4.16 (0)2025.3.0 (Calculator: 2025.3).
Compliance Exposure Standard: FCC OET 65.
The parameters used for modeling are summarized in the Site Description antenna inventory table
in Section 1.
Modeling Results
At ground level, the maximum cumulative exposure level from Verizon Wireless at this Site is
approximately 4.753 percent of the FCC’s general population limit (0.9506 percent of the FCC’s
occupational limit).
Notwithstanding, workers climbing the Monopine should be informed about the presence and
locations of antennas and their associated fields.
A site would be 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.

Since Verizon Wireless will be the only carrier at this Site, Verizon Wireless will be responsible for
any mitigation (if required) in connection with the Facility.
As the site is in compliance with applicable FCC limits as designed, and in accordance with the official
Verizon Wireless Signage and Demarcation Policy for tower structures, no signage is recommended
at this site.
The inputs used in the modeling are summarized in the Site Description antenna inventory table in
Section 1. Signage recommendations based on the IXUS™ modeling results are presented in
Appendix B.

3. Mitigation/Site Control Options
EBI’s modeling indicates that there are no areas in front of the Verizon antennas that exceed the
FCC standards for occupational or general public exposure. All exposures above the FCC’s safe
limits require that individuals be elevated above the ground. In accordance with the official Verizon
Wireless Signage and Demarcation Policy for tower structures, no signage is recommended at this
site.
There are no barriers recommended on this site.
These protocols and recommended control measures have been summarized and included with a
graphic representation of the antennas and associated signage and control areas in a RF-EME Site
Safety Plan, which is included as Appendix B. Individuals and workers accessing the Monopine
should be provided with a copy of the attached Site Safety Plan, made aware of the posted signage,
and signify their understanding of the Site Safety Plan.
To reduce any exposure, EBI recommends that access to the Monopine or areas associated with the active
antenna installation be restricted and secured where possible. All persons accessing elevated positions on
adjacent structures (ex. rooftop, utility pole, monopole, etc.) along with nearby elevated features,
such as trees, within areas exceeding the general public MPE, must be made aware of the presence
and locations of antennas and their associated fields, where applicable.

4. Summary and Conclusions
EnviroBusiness Inc. (dba EBI Consulting) has prepared a Radiofrequency – Electromagnetic Energy
(RF-EME) Compliance Report for Verizon Wireless site Feather Falls Casino, located at Ophir Road,
Oroville, CA 95966to determine RF-EME exposure levels from proposed telecommunications
equipment at this site. This report summarizes the results of RF-EME modeling in relation to
relevant Federal Communications Commission (FCC) RF-EME compliance standards for limiting
human exposure to RF-EME fields.
As presented in the sections above, based on the FCC criteria, there are no modeled areas on any
accessible roof level walking/working surface related to the Verizon antennas that exceed the FCC’s
occupational or general public exposure limits at this site.
Workers should be informed about the presence and locations of antennas and their associated
fields. Recommended control measures are outlined in Appendix B – Radio Frequency
Electromagnetic Energy Safety Information and Signage Plans; Verizon Wireless should also provide
procedures to shut down and lockout/tagout this wireless equipment in accordance with their own
standard operating protocol. Non-telecom workers who will be working in areas of exceedance are
required to contact Verizon Wireless since only Verizon Wireless has the ability to lockout/tagout
the facility, or to authorize others to do so.

Appendix C – 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 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 (mW) over a unit surface area (cm2). Known as the power
density, the FCC has established an occupational MPE of 5 milliwatts per square centimeter (mW/cm2) and an
uncontrolled MPE of 1 mW/cm2 for equipment operating in the 1900 MHz frequency range. These limits are
considered protective of these populations.

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
Frequency Occupational MPE Public MPE
Microwave (Point-to-Point) 5,000 - 80,000
MHz 5.00 mW/cm2 1.00 mW/cm2
Broadband Radio (BRS) 2,600 MHz 5.00 mW/cm2 1.00 mW/cm2
Wireless Communication (WCS) 2,300 MHz 5.00 mW/cm2 1.00 mW/cm2
Advanced Wireless (AWS) 2,100 MHz 5.00 mW/cm2 1.00 mW/cm2
Personal Communication (PCS) 1,950 MHz 5.00 mW/cm2 1.00 mW/cm2
Cellular Telephone 870 MHz 2.90 mW/cm2 0.58 mW/cm2
Specialized Mobile Radio (SMR) 855 MHz 2.85 mW/cm2 0.57 mW/cm2
Long Term Evolution (LTE) 700 MHz 2.33 mW/cm2 0.47 mW/cm2
Most Restrictive Frequency Range 30-300 MHz 1.00 mW/cm2 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 wireless carriers in this area will potentially operate within a
frequency range of 600 to 5000 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.
