AGENCY: Federal Aviation Administration (FAA); Department of
Transportation (DOT):
ACTION: Notification of amended policy.
-----------------------------------------------------------------------
SUMMARY: The FAA announces an amendment to its Colo Void policy. The
FAA last revised its policy regarding the notification requirements and
processes for evaluation of potential electromagnetic interference
(EMI) for co-location of antenna systems on existing structures
previously studied by the FAA on November 21, 2007. Based on an August
4, 2020 request from the Colo Void Clause Coalition (CVCC), the FAA
finds that further modifications to this policy are necessary and
appropriate. The FAA will add additional frequencies to the list of
those not requiring notice to the FAA when added to an existing
structure with a current No Hazard Determination.
DATES: This policy is effective September 6, 2022.
FOR FURTHER INFORMATION CONTACT: For specific questions related to the
Colo Void policy, please contact the Spectrum Engineering Group, 202-
267-7365.
SUPPLEMENTARY INFORMATION:
Background
Prior to April 2004, when the FAA issued a Determination of No
Hazard to Air Navigation for proposed construction or alteration of an
antenna structure, the Determination included the following condition:
``This determination is based, in part, on the foregoing description
which includes specific coordinates, heights, frequency(ies) and power.
Any changes in coordinates, heights, frequency(ies) or use of greater
power will void this determination. Any future construction or
alteration, including an increase in
[[Page 39747]]
heights, power, or the addition of other transmitters requires separate
notice to the FAA.'' As a result of this condition, a proponent seeking
only to add frequencies to a previously studied structure for which the
FAA had issued a Determination of No Hazard was required to file notice
with the FAA. They had to file the notice on FAA Form 7460-1 in
accordance with the previously discussed condition.
On April 27, 2004, the FAA published a revised policy regarding the
notification requirements for co-locating antenna systems on existing
structures previously studied by the FAA (69 FR 22732). The revised
policy was based on a Best Practices Agreement recommended by the Colo
Void Clause Coalition (CVCC).\1\ Under this revised policy, a proponent
was not required to file notices with the FAA for an aeronautical study
to add certain frequencies to an existing structure that FAA issued a
current Determination of No Hazard to Air Navigation.
---------------------------------------------------------------------------
\1\ The CVCC represents wireless service providers and tower
companies that together currently own or manage the majority of the
radio towers throughout the United States.
---------------------------------------------------------------------------
In February 2006, the CVCC asked the FAA to consider amending its
policy to include additional frequency bands. The CVCC also sought
clarification of the condition in the 2004 policy requiring proponents
to provide the FAA with an electronic copy of its antenna system
location databases. On November 21, 2007, the FAA further amended the
policy to add the requested frequencies (72 FR 65449). FAA also
withdrew the condition requiring proponents to provide electronic
copies of antenna system location databases because any unintentional
electromagnetic interference resulting under the policy can be
mitigated by condition 2 of the policy.\2\
---------------------------------------------------------------------------
\2\ Condition 2--If an antenna system, operating in the
designated frequency bands, causes EMI to one or more FAA
facilities, the FAA will contact the proponent. The proponent must
mitigate the EMI in a timely manner, as recommended by the FAA in
each particular case. Depending upon the severity of the
interference, the proponent must eliminate harmful EMI either by
adjusting operating parameters, (for example, employing extra
filtering or reducing effective radiated power), or by ceasing
transmissions, as may be required by the FCC and the FAA. Failure to
provide successful EMI mitigation techniques will result in referral
to the FCC's Enforcement Bureau for possible enforcement action. (69
FR 22732; April 27, 2004).
---------------------------------------------------------------------------
On August 4, 2020, the CVCC requested that the FAA consider
amending the November 21, 2007 policy by including additional frequency
bands not requiring notice to the FAA when co-located with previously
studied structures with No Hazard determinations. The frequencies are
those that the Federal Communications Commission (FCC) has authorized
for use by wireless companies.\3\ The FCC reviewed the bands and
associated technical rules to ensure their use of the bands would not
cause harmful effects to other users operating in the same bands.
Furthermore, many of these commercial radio frequency systems use
technology that are industry and federally approved. The FAA agrees
with the FCC's evaluation, and after careful review and coordination,
has determined that it can include most of the requested additional
frequencies by amending the current Colo Void policy. These additional
frequencies will promote telecommunication and wireless services, while
not negatively impacting either the safety or efficiency of civil
flight.
---------------------------------------------------------------------------
\3\ AT&T, a member of the CVCC, separately requested the
addition of the 3.45 GHz band.
---------------------------------------------------------------------------
Policy
The FAA recognizes the telecommunications industry's need and
commitment to provide wireless services to the public. Also, the FAA
recognizes that it is essential for these companies to speed up the
time frame for build-out and deployment of their networks. However, the
FAA's first commitment is to aviation safety. For that reason, the FAA
finds that it can amend its policy to add most, but not all, of the
frequencies requested by the CVCC. As has been the case with previous
policy updates, the express notice requirements under part 77 of Title
14 Code of Federal Regulations (CFR) are not altered or modified. If
the addition of frequencies is accompanied by an increase in the height
of a previously studied structure, notice must be filed with the FAA as
required by 14 CFR 77.9.\4\ Physical structures located on or near
public use and other types of landing facilities defined in 14 CFR
77.9(d) raise concerns about possible obstruction to air navigation,
and the FAA will handle these issues pursuant to current regulations
and procedures.
---------------------------------------------------------------------------
\4\ This citation changed when the FAA amended part 77 in 2010
from Sec. 77.13 to Sec. 77.9.
---------------------------------------------------------------------------
Under this policy, a proponent is not required to file notice with
the FAA to add frequencies to an existing structure that either has a
current FAA issued Determination of No Hazard to Air Navigation or
otherwise does not meet notice criteria if the frequency is listed in
this policy. If an additional antenna system must be used to add
frequencies, the antenna system must not be located on Federal or
public use landing facilities property.
Furthermore, the antenna system must not be co-located or mounted
on an FAA antenna structure without prior coordination with the FAA's
Spectrum Engineering Group. This policy to not require notice only
applies to antenna systems operating on the following frequencies and
service types, as dictated by various parts of 47 CFR. FAA is updating
the policy to include additional frequencies. In some instances, the
frequencies added by this notice are subject to designated power and
bandwidth limitations. These limitations are specified where
applicable. The new frequencies are designated with an asterisk.

In addition, the following conditions also apply to this Colo Void
policy. First, if an antenna system, operating in the designated
frequency bands, causes EMI to air navigation, including communication
facilities and aviation radio frequency services, the FAA will contact
the proponent. The proponents must mitigate the EMI in a timely manner,
as recommended by the FAA in each particular case. Depending on the
severity of the interference, the proponent must eliminate harmful EMI
either by adjusting operating parameters (for example, employing extra
filtering or reducing effective radiated power), or by ceasing
transmissions, as may be required by the FCC and the FAA. Failure to
provide successful EMI mitigation techniques will result in referral to
the FCC's Enforcement Bureau for possible enforcement action. Second,
this policy only applies to current technologies and modulation
techniques (for example, analog, time division multiple access, and
Global System Mobile Communications) existing in the wireless
radiotelephone environment on the date of issuance of this policy. Any
future technologies placed into commercial service by wireless service
providers, although operating on the frequencies mentioned above, must
provide notification to the FAA under 14 CFR part 77 procedures.
As has been the case with previous policy updates, the FAA will
continue to revise the conditional language in future cases involving
Determination of No Hazard to Air Navigation to reflect this policy.
Furthermore, this policy applies retroactively to any structure for
which the FAA has issued a Determination of No Hazard to Air
Navigation.
