Subpart A_General Information
Sec. 17.1 Basis and purpose.
(a) The rules in this part are issued pursuant to the authority
contained in Title III of the Communications Act of 1934, as amended,
which vest authority in the Federal Communications Commission to issue
licenses to radio stations when it is found that the public interest,
convenience, and necessity would be served thereby, and to require the
painting, and/or illumination of antenna structures if and when in its
judgment such structures constitute, or there is reasonable possibility
that they may constitute, a menace to air navigation.
(b) The purpose of this part is to prescribe certain procedures for
antenna structure registration and standards with respect to the
Commission's consideration of proposed antenna structures which will
serve as a guide to antenna structure owners. The standards are
referenced from two Federal Aviation Administration (FAA) Advisory
Circulars.
[61 FR 4362, Feb. 6, 1996]
Sec. 17.2 Definitions.
(a) Antenna structure. The term antenna structure includes the
radiating and/or receive system, its supporting structures and any
appurtenances mounted thereon.
(b) An antenna farm area is defined as a geographical location, with
established boundaries, designated by the Federal Communications
Commission, in which antenna towers with a common impact on aviation may
be grouped.
(c) Antenna structure owner. For the purposes of this part, an
antenna structure owner is the individual or entity vested with
ownership, equitable ownership, dominion, or title to the antenna
structure. Notwithstanding any agreements made between the owner and any
entity designated by the owner to maintain the antenna structure, the
owner is ultimately responsible for compliance with the requirements of
this part.
(d) Antenna structure registration number. A unique number, issued
by the Commission during the registration process, which identifies an
antenna structure. Once obtained, this number must be used in all
filings related to this structure.
[32 FR 8813, June 21, 1967, and 32 FR 11268, Aug. 3, 1967, as amended at
39 FR 26157, July 17, 1974; 61 FR 4362, Feb. 6, 1996]
Sec. 17.4 Antenna structure registration.
(a) Effective July 1, 1996, the owner of any proposed or existing
antenna structure that requires notice of proposed construction to the
Federal Aviation Administration must register the structure with the
Commission. This includes those structures used as part of stations
licensed by the Commission for the transmission of radio energy, or to
be used as part of a cable television head end system. If a Federal
Government antenna structure is to be used by a Commission licensee, the
structure must be registered with the Commission.
(1) For a proposed antenna structure or alteration of an existing
antenna structure, the owner must register the structure prior to
construction or alteration.
(2) For an existing antenna structure that had been assigned
painting or lighting requirements prior to July 1, 1996, the owner must
register the structure prior to July 1, 1998.
(3) For a structure that did not originally fall under the
definition of ``antenna structure,'' the owner must register the
structure prior to hosting a Commission licensee.
(b) Except as provided in paragraph (e) of this section, each owner
must file FCC Form 854 with the Commission. Additionally, each owner of
a proposed structure referred to in paragraphs (a)(1) or (a)(3) of this
section must submit a valid FAA determination of ``no hazard.'' In order
to be considered valid
[[Page 851]]
by the Commission, the FAA determination of ``no hazard'' must not have
expired prior to the date on which FCC Form 854 is received by the
Commission. The height of the structure will include the highest point
of the structure including any obstruction lighting or lighting
arrester.
(c) If an Environmental Assessment is required under Sec. 1.1307 of
this chapter, the Bureau will address the environmental concerns prior
to processing the registration.
(d) If a final FAA determination of ``no hazard'' is not submitted
along with FCC Form 854, processing of the registration may be delayed
or disapproved.
(e) If the owner of the antenna structure cannot file FCC Form 854
because it is subject to a denial of Federal benefits under the Anti-
Drug Abuse Act of 1988, 21 U.S.C. 862, the first tenant licensee
authorized to locate on the structure (excluding tenants that no longer
occupy the structure) must register the structure using FCC Form 854,
and provide a copy of the Antenna Structure Registration (FCC Form 854R)
to the owner. The owner remains responsible for providing a copy of FCC
Form 854R to all tenant licensees on the structure and for posting the
registration number as required by paragraph (g) of this section.
(f) The Commission shall issue, to the registrant, FCC Form 854R,
Antenna Structure Registration, which assigns a unique Antenna Structure
Registration Number. The structure owner shall immediately provide a
copy of Form 854R to each tenant licensee and permittee.
(g) Except as described in paragraph (h) of this section, the
Antenna Structure Registration Number must be displayed in a conspicuous
place so that it is readily visible near the base of the antenna
structure. Materials used to display the Antenna Structure Registration
Number must be weather-resistant and of sufficient size to be easily
seen at the base of the antenna structure.
(h) The owner is not required to post the Antenna Structure
Registration Number in cases where a federal, state, or local government
entity provides written notice to the owner that such a posting would
detract from the appearance of a historic landmark. In this case, the
owner must make the Antenna Structure Registration Number available to
representatives of the Commission, the FAA, and the general public upon
reasonable demand.
[61 FR 4362, Feb. 6, 1996]
Sec. 17.5 Commission consideration of applications for station
authorization.
(a) Applications for station authorization, excluding services
authorized on a geographic basis, are reviewed to determine whether
there is a requirement that the antenna structure in question must be
registered with the Commission.
(b) If registration is required, the registrant must supply the
structure's registration number upon request by the Commission.
(c) If registration is not required, the application for
authorization will be processed without further regard to this chapter.
[61 FR 4362, Feb. 6, 1996]
Sec. 17.6 Responsibility of Commission licensees and permittees.
(a) The antenna structure owner is responsible for maintaining the
painting and lighting in accordance with this part. However, if a
licensee or permittee authorized on an antenna structure is aware that
the structure is not being maintained in accordance with the
specifications set forth on the Antenna Structure Registration (FCC Form
854R) or the requirements of this part, or otherwise has reason to
question whether the antenna structure owner is carrying out its
responsibility under this part, the licensee or permittee must take
immediate steps to ensure that the antenna structure is brought into
compliance and remains in compliance. The licensee must:
(1) Immediately notify the structure owner;
(2) Immediately notify the site management company (if applicable);
(3) Immediately notify the Commission; and,
(4) Make a diligent effort to immediately bring the structure into
compliance.
[[Page 852]]
(b) In the event of non-compliance by the antenna structure owner,
the Commission may require each licensee and permittee authorized on an
antenna structure to maintain the structure, for an indefinite period,
in accordance with the Antenna Structure Registration (FCC Form 854R)
and the requirements of this part.
(c) If the owner of the antenna structure cannot file FCC Form 854
because it is subject to a denial of Federal benefits under the Anti-
Drug Abuse Act of 1988, 21 U.S.C. 862, the first licensee authorized to
locate on the structure must register the structure using FCC Form 854,
and provide a copy of the Antenna Structure Registration (FCC Form 854R)
to the owner. The owner remains responsible for providing a copy of FCC
Form 854R to all tenant licensees on the structure and for posting the
registration number as required by Sec. 17.4(g).
[61 FR 4363, Feb. 6, 1996]
Subpart B_Federal Aviation Administration Notification Criteria
Sec. 17.7 Antenna structures requiring notification to the FAA.
A notification to the Federal Aviation Administration is required,
except as set forth in Sec. 17.14, for any of the following
construction or alteration:
(a) Any construction or alteration of more than 60.96 meters (200
feet) in height above ground level at its site.
(b) Any construction or alteration of greater height than an
imaginary surface extending outward and upward at one of the following
slopes:
(1) 100 to 1 for a horizontal distance of 6.10 kilometers (20,000
feet) from the nearest point of the nearest runway of each airport
specified in paragraph (d) of this section with at least one runway more
than 0.98 kilometers (3,200 feet) in actual length, excluding heliports.
(2) 50 to 1 for a horizontal distance of 3.05 kilometers (10,000
feet) from the nearest point of the nearest runway of each airport
specified in paragraph (d) of this section with its longest runway no
more than 0.98 kilometers (3,200 feet) in actual length, excluding
heliports.
(3) 25 to 1 for a horizontal distance of 1.52 kilometers (5,000
feet) from the nearest point of the nearest landing and takeoff area of
each heliport specified in paragraph (d) of this section.
(c) When requested by the FAA, any construction or alteration that
would be in an instrument approach area (defined in the FAA standards
governing instrument approach procedures) and available information
indicates it might exceed an obstruction standard of the FAA.
(d) Any construction or alteration on any of the following airports
(including heliports):
(1) An airport that is available for public use and is listed in the
Airport Directory of the current Airman's Information Manual or in
either the Alaska or Pacific Airman's Guide and Chart Supplement.
(2) An airport under construction, that is the subject of a notice
or proposal on file with the Federal Aviation Administration, and except
for military airports, it is clearly indicated that the airport will be
available for public use.
(3) An airport that is operated by an armed force of the United
States.
Note: Consideration to aeronautical facilities not in existence at
the time of the filing of the application for radio facilities will be
given only when proposed airport construction or improvement plans are
on file with the Federal Aviation Administration as of the filing date
of the application for such radio facilities.
[39 FR 7581, Feb. 27, 1974, as amended at 39 FR 26157, July 17, 1974; 42
FR 54823, Oct. 11, 1977; 42 FR 57127, Nov. 1, 1977]
Sec. 17.8 Establishment of antenna farm areas.
(a) Each antenna farm area will be established by an appropriate
rulemaking proceeding, which may be commenced by the Commission on its
own motion after consultation with the FAA, upon request of the FAA, or
as a result of a petition filed by any interested person. After receipt
of a petition from an interested person disclosing sufficient reasons to
justify institution of a rulemaking proceeding, the Commission will
request the advice of the FAA with respect to the considerations of
menace to air navigation in terms of
[[Page 853]]
air safety which may be presented by the proposal. The written
communication received from the FAA in response to the Commission's
request shall be placed in the Commission's public rulemaking file
containing the petition, and interested persons shall be allowed a
period of 30 days within which to file statements with respect thereto.
Such statements shall also be filed with the Administrator of the FAA
with proof of such filing to be established in accordance with Sec.
1.47 of this chapter. The Administrator of the FAA shall have a period
of 15 days within which to file responses to such statements. If the
Commission, upon consideration of the matters presented to it in
accordance with the above procedure, is satisfied that establishment of
the proposed antenna farm would constitute a menace to air navigation
for reasons of air safety, rulemaking proceedings will not be
instituted. If rulemaking proceedings are instituted, any person filing
comments therein which concern the question of whether the proposed
antenna farm will constitute a menace to air navigation shall file a
copy of the comments with the Administrator of the FAA. Proof of such
filing shall be established in accordance with Sec. 1.47 of this
chapter.
(b) Nothing in this subpart shall be construed to mean that only one
antenna farm area will be designated for a community. The Commission
will consider on a case-by-case basis whether or not more than one
antenna farm area shall be designated for a particular community.
[32 FR 8813, June 21, 1967, as amended at 32 FR 13591, Sept. 28, 1967]
Sec. 17.9 Designated antenna farm areas.
The areas described in the following paragraphs of this section are
established as antenna farm areas [appropriate paragraphs will be added
as necessary].
[32 FR 8813, June 21, 1967]
Sec. 17.10 Antenna structures over 304.80 meters (1,000 feet) in height.
Where one or more antenna farm areas have been designated for a
community or communities (see Sec. 17.9), the Commission will not
accept for filing an application to construct a new station or to
increase height or change antenna location of an existing station
proposing the erection of an antenna structure over 304.80 meters (1,000
feet) above ground unless:
(a) It is proposed to locate the antenna structure in a designated
antenna farm area, or
(b) It is accompanied by a statement from the Federal Aviation
Administration that the proposed structure will not constitute a menace
to air navigation, or
(c) It is accompanied by a request for waiver setting forth reasons
sufficient, if true, to justify such a waiver.
[32 FR 8813, June 21, 1967, as amended at 42 FR 54824, Oct. 11, 1977; 61
FR 4363, Feb. 6, 1996]
Sec. 17.14 Certain antenna structures exempt from notification to the FAA.
A notification to the Federal Aviation Administration is not
required for any of the following construction or alteration:
(a) Any object that would be shielded by existing structures of a
permanent and substantial character or by natural terrain or topographic
features of equal or greater height, and would be located in the
congested area of a city, town, or settlement where it is evident beyond
all reasonable doubt that the structure so shielded will not adversely
affect safety in air navigation. Applicant claiming such exemption under
Sec. 17.14(a) shall submit a statement with their application to the
FCC explaining basis in detail for their finding.
(b) Any antenna structure of 6.10 meters (20 feet) or less in height
except one that would increase the height of another antenna structure.
(c) Any air navigation facility, airport visual approach or landing
aid, aircraft arresting device, or meteorological device, of a type
approved by the Administrator of the Federal Aviation Administration,
the location and height of which is fixed by its functional purpose.
[32 FR 11269, Aug. 3, 1967, as amended at 39 FR 7581, Feb. 27, 1974; 42
FR 54824, Oct. 11, 1977; 61 FR 4363, Feb. 6, 1996]
[[Page 854]]
Sec. 17.17 Existing structures.
(a) The requirements found in Sec. 17.23 relating to painting and
lighting of antenna structures shall not apply to those structures
authorized prior to July 1, 1996. Previously authorized structures may
retain their present painting and lighting specifications, so long as
the overall structure height or site coordinates do not change. The
Antenna Structure Registration requirements found in Sec. 17.5,
however, shall apply to all antenna structures that have been assigned
painting or lighting requirements by the Commission, regardless of prior
authorization.
(b) No change in any of these criteria or relocation of airports
shall at any time impose a new restriction upon any then existing or
authorized antenna structure or structures.
[32 FR 11269, Aug. 3, 1967, as amended at 61 FR 4363, Feb. 6, 1996]
Subpart C_Specifications for Obstruction Marking and Lighting of Antenna
Structures
Sec. 17.21 Painting and lighting, when required.
Antenna structures shall be painted and lighted when:
(a) They exceed 60.96 meters (200 feet) in height above the ground
or they require special aeronautical study.
(b) The Commission may modify the above requirement for painting
and/or lighting of antenna structures, when it is shown by the applicant
that the absence of such marking would not impair the safety of air
navigation, or that a lesser marking requirement would insure the safety
thereof.
[32 FR 11269, Aug. 3, 1967, as amended at 42 FR 54824, Oct. 11, 1977]
Sec. 17.22 Particular specifications to be used.
Whenever painting or lighting is required, the Commission will
generally assign specifications in accordance with the FAA Advisory
Circulars referenced in Sec. 17.23. If an antenna installation is of
such a nature that its painting and lighting in accordance with these
specifications are confusing, or endanger rather than assist airmen, or
are otherwise inadequate, the Commission will specify the type of
painting and lighting or other marking to be used in the individual
situation.
[32 FR 11269, Aug. 3, 1967, as amended at 61 FR 4363, Feb. 6, 1996]
Sec. 17.23 Specifications for painting and lighting antenna structures.
Unless otherwise specified by the Commission, each new or altered
antenna structure to be registered on or after January 1, 1996, must
conform to the FAA's painting and lighting recommendations set forth on
the structure's FAA determination of ``no hazard,'' as referenced in the
following FAA Advisory Circulars: AC 70/7460-1J, ``Obstruction Marking
and Lighting,'' effective January 1, 1996, and AC 150/5345-43E,
``Specification for Obstruction Lighting Equipment,'' dated October 19,
1995. These documents are incorporated by reference in accordance with 5
U.S.C. 552(a). The documents contain FAA recommendations for painting
and lighting structures which pose a potential hazard to air navigation.
For purposes of this part, the specifications, standards, and general
requirements stated in these documents are mandatory. The Advisory
Circulars listed are available for inspection at the Commission
Headquarters in Washington, DC, or may be obtained from Department of
