RE: Verizon Wireless Stealth Tree site Located at 2766 St. Louis Ave. Signal Hill, CA 90755.
To Whom It May Concern,
We write to inform you that Verizon Wireless has performed a radio frequency (RF) compliance pre-construction evaluation for the above-noted proposed site and based on the result of the evaluation, the site will be compliant with FCC Guidelines.
The FCC has established safety rules relating to potential RF exposure from cell sites. The rules are codified at 47 C.F.R § 1.1310. The FCC provides guidance on how to ensure compliance with its rules in the FCC Office of Engineering and Technology Bulletin 65 (available at https://transition.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet65/oet65.pdf). The FCC developed the RF standards, known as Maximum Permissible Exposure (MPE) limits, in consultation with numerous other federal agencies, including the Environmental Protection Agency, the Food and Drug Administration, and the Occupational Safety and Health Administration. The FCC provides information about the safety of radio frequency (RF) emissions from cell towers on its website at:
https://www.fcc.gov/engineering-technology/electromagnetic-compatibility-division/radio-frequencysafety/faq/rf-safety.
Please refer to the FCC Office of Engineering and Technology Bulletin 65 and the attached Verizon Wireless RF Brochure for information on RF exposure guidelines, RF safety, and landlord responsibilities. Questions related to compliance with federal regulations should be directed to [email protected].
Please contact your local Verizon Wireless resource below if you have additional site-specific questions.

REFERENCE GUIDE
This handout is not intended to replace the FCC/OSHA mandated occupational requirement for RF Safety & Awareness Training • Assume that all antennas are active
• Obey all posted signs
• Do not stop in front of any antenna
• Recognize the type of antenna and approach at the
safest angle
• Contact wireless operator to coordinate access if
required
• Signage will indicate where potential RF conditions
exist
• Understand pathways of safe egress
GENERAL EXPOSURE MANAGEMENT
• If needed and possible wear personal protection
equipment
• When using a personal monitor, remember the time
averaging limits and monitor alarm thresholds if
working in front of antennas
• If experiencing symptoms of heat exhaustion or
nausea, remove yourself from the worksite and seek
medical attention
• Power density decreases with distance so maintain
distance between you and the antennas. The greater
the distance you are from an antenna the bigger the
reduction of RF exposure you will receive
The Federal Communications Commission (FCC) has
established safety guidelines relating to RF exposure
from cell sites. The FCC developed those standards,
known as Maximum Permissible Exposure (MPE)
limits, in consultation with numerous other federal
agencies, including the Environmental Protection
Agency, the Food and Drug Administration, and the
Occupational Safety and Health Administration.
The standards were developed by expert scientists
and engineers after extensive reviews of the scientific literature related to RF biological effects. The FCC
explains that its standards incorporate prudent
margins of safety.
Areas or portions of any transmitter site may be
susceptible to high power densities that could
cause personnel exposures in excess of the FCC
guidelines. Wireless Licensees are required by law
to implement the following:
• Restrict access
• Post notification signage on every access point to
increase awareness of the potential for exposure
BEFORE one enters an area with antennas.
• Place additional notification signage and visual
indicators in an area with antennas (beyond an
access point) where RF exposure levels may
start to exceed the FCC’s limits.
Persons are “exposed
as a consequence of
their employment” and
are “fully aware of the
potential for exposure
and can exercise control
over their exposure.”
Any persons that “may
not be made fully
aware of the potential
for exposure or cannot
exercise control over
their exposure.”

• Omni antennas have the appearance of
a rod-shaped pole and radiate in a 360°
pattern around the pole.
• At the antenna level, there is no approach
angle that is safer than another. Typically,
emissions directly below the antenna are
less than in front of the antenna.
OMNI ANTENNA
• Range from 1 to 8 feet in length
• Sled mounted or to a support structure
on site (Rooftop)
• Approach these antennas from the rear.
PANEL ANTENNA
• Quasi-Omni antennas have the appearance
of a cylinder and contain emitters that
radiate in a 360°pattern around the pole.
• At the antenna level, there is no approach
angle that is safer than another. Typically,
emissions directly below the antenna are
less than in front of the antenna.
QUASI-OMNI ANTENNA
TYPES OF ANTENNAS
• Highly directional antenna model used for
point to point communications
• Approach from the rear and sides. Do
not stand or walk in front of microwaves
as they transmit at a high frequency.
MICROWAVE ANTENNA
• Directional antenna model
• Approach from sides and rear.

RF exposure safety and the protection of every licensee’s infrastructure are very important. Property owners and licensees have a shared responsibility in maintaining a safe and secure RF environment. Property owners can help in this significant endeavor by:
• Maintaining all necessary wireless licensee contact information. • Enforcing restricted access (help maintain a Controlled Environment). Ensuring all building/maintenance personnel are trained in RF Safety, aware that the potential for exposure exists, and follow all appropriate entry and safety procedures.
• Notifying all licensees when any non-carrier requests access to any area with antennas at least 24 hours in advance.
• Understanding that compliance with the FCC and OSHA can be achieved with RF Exposure levels above the applicable limit if the proper signage, physical/indicative barrier, and access restrictions are implemented. Commitment to compliance and willingness to cooperate are essential.
