The Commission published the notice of proposed rulemaking (NPRM) at 86
FR 43145 on August 6, 2021.
Synopsis
1. The Federal Communication Commission amends the following rules
applicable to broadcast radio stations to better reflect current
requirements and eliminate redundant, outdated, or conflicting
technical provisions.
2. Maximum rated transmitter power for AM stations. The Commission
amends 47 CFR 73.1665(b) to remove the maximum rated transmitter power
limit for AM stations and deletes the corresponding ``Table 1 to
paragraph (b).'' This equipment limitation on potential transmitter
power is outdated and unnecessary given the Commission's current
reliance on actual operating antenna input power as the most accurate
and effective means of ensuring that AM stations adhere to their
authorized power limits. The Commission anticipates that elimination of
this technical restriction on AM transmitters will allow AM stations of
any class to use transmitters of any rated power, thus benefiting the
AM service by broadening the market of transmitters available to
stations, enhancing the secondary market for AM transmitters, and
reducing the number of transmitters that need to be disposed of.
Accordingly, it amends 47 CFR 73.1665(b) by removing the maximum rated
transmitter power for AM stations, deletes the ``Table 1 to paragraph
(b),'' and replaces ``power rating limit'' in the first sentence with
``manufacturer-rated power limit'' to indicate that this is a technical
specification established by the transmitter manufacturer.
3. Noncommercial Educational (NCE) community of license coverage.
The Commission eliminates the inconsistency between 47 CFR
73.316(c)(2)(ix)(B) and 73.1690(c)(8)(i) and the NCE FM community
coverage standard set out in 47 CFR 73.515. Specifically, it amends
[[Page 15340]]
Sec. Sec. 73.316(c)(2)(ix)(B) and 73.1690(c)(8)(i) to conform to the
updated standard that NCE applicants must show that their predicted 60
dBu contour will cover at least 50% of the relevant community of
license or reach 50% of the population within the community.
4. FM transmitter interference to nearby antennas. The Commission
declines to eliminate the proximate interference rule, 47 CFR
73.316(d), on the basis of industry feedback. However, it correct a
typographical error in this rule by replacing the word ``approximate''
with ``proximate.''
5. NCE FM Class D second-adjacent channel interference ratio. The
Commission amends 47 CFR 73.509(b), which sets out signal strength
contour overlap requirements for NCE FM Class D stations, to harmonize
with the more permissive standard applied to all other NCE-FM stations.
The Commission states that the less restrictive requirements have
proven effective for other station classes and that there is no reason
to continue treating Class D stations differently in this context.
Although this distinction was originally designed to accommodate the
establishment of the low power FM (LPFM) service, because the LPFM
service is now mature, it is appropriate to extend the general contour
overlap limits to Class D NCE stations. The Commission anticipates that
the less preclusive requirement will create opportunities for NCE
stations to increase power and coverage, as well as provide them with
greater site selection flexibility. Accordingly, it amends 47 CFR
73.509(b) as set out in the final rules and makes non-substantive and
formatting edits to the table contained in 47 CFR 73.509(a).
6. Protection for grandfathered common carriers in Alaska in the
76-100 MHz band. The Commission deletes 47 CFR 73.501(b),
74.1202(b)(3), the second sentence of 74.702(a)(1), and the second
sentence of 74.786(b), all containing similar language requiring
broadcast services to protect grandfathered common carrier services in
Alaska operating in the 76-100 MHz frequency band. The Commission
explains that this requirement is unnecessary and obsolete because the
Commission's licensing databases indicate that there are no longer any
common carrier services remaining in this frequency band in Alaska.
7. AM fill-in area definition. The Commission amends the definition
of ``AM fill-in area'' set out in 47 CFR 74.1201(j) to conform to the
requirement in 47 CFR 74.1201(g) that the ``coverage contour of an FM
translator rebroadcasting an AM radio broadcast station as its primary
station must be contained within the greater of either the 2 mV/m
daytime contour of the AM station or a 25-mile (40 km) radius centered
at the AM transmitter site.'' This change harmonizes the various rules
governing fill-in translator transmitter siting and does not affect the
signal coverage requirement set out in 47 CFR 74.1201(g).
8. International coordinations. The Commission updates 47 CFR
73.207(b) and 74.1235(d) to comport with the relevant international
treaties. Specifically, it updates 47 CFR 73.207(b)(2) and the
associated table to reflect the spacing requirements set out in the
1997 amendment to the 1991 U.S.-Canada FM Broadcasting Agreement and to
reference the contour overlap provisions of section 5.2 of the
Agreement. The Commission concludes that there is no need to
grandfather stations that do not meet the new requirements because, at
the time that the 1997 amendment took effect, the Commission
coordinated with Canada Table B allotment modifications in accordance
with the increase of Class A allotments to 6kW and has subsequently
applied the distance separations set out in the amended 1991 U.S.-
Canada FM Broadcasting Agreement when processing applications for more
than two decades. The Commission clarifies that no facility
modifications will be ordered because of the administrative updates to
the distance separation requirements and that any Class A FM station
may continue to operate under its licensed parameters. However, any
application to modify the technical parameters in the station's license
must include a showing that the proposed facilities satisfy the treaty
requirements with respect to the Canadian border as set out in amended
47 CFR 73.207(b)(2).
9. The Commission also updates 47 CFR 73.207(b)(3) and the
associated table to reflect the spacing requirements set out in the
1992 U.S.-Mexico FM Broadcasting Agreement. It clarifies that, for the
purposes of the table associated with 47 CFR 73.207(b)(3), U.S. Class
C0 assignments or allotments are considered Class C. In addition, the
Commission states that the distances in both 47 CFR 73.207(b)(2) and
(3) are to be calculated using the distance calculation methodology set
out in the two respective Agreements. Finally, it makes non-substantive
and formatting edits to all of the minimum distance separation tables
contained in 47 CFR 73.207(b).
10. The Commission also updates 47 CFR 74.1235(d) to eliminate
inconsistent provisions and reflect current treaty requirements
applicable to FM translators. Specifically, it deletes all of the
current introductory language of paragraph (d) prior to paragraphs
(d)(1), (2), and (3). The first sentence of that introductory paragraph
is inconsistent with the current treaty power limits established in the
1991 U.S.-Canada FM Broadcasting Agreement, as amended, which are
already codified in paragraph (d)(3). The remainder of the introductory
paragraph is inconsistent with the terms of the 1992 U.S.-Mexico FM
Broadcasting Agreement, which specifies that FM translator stations are
subject to a contour overlap based spacing methodology and are thus not
subject to the distance separations of 47 CFR 73.207(b)(3). Finally,
the reference in that paragraph to a 10-watt transmitter power output
limitation is a superseded provision originally set out in the U.S.-
Mexican FM Broadcast Agreement of 1972 and is no longer required under
the current treaty. For these reasons, the Commission deletes all of
the introductory language of Sec. 74.1235(d) as obsolete.
Paperwork Reduction Act Analysis
11. This document does not contain proposed new or modified
information collection requirements subject to the Paperwork Reduction
Act of 1995 (PRA), Public Law 104-13. In addition, therefore, it does
not contain any new or modified information collection for small
business concerns with fewer than 25 employees, pursuant to the Small
Business Paperwork Relief Act of 2002, Public Law 107-198, see 44
U.S.C. 3506(c)(4).
Final Regulatory Flexibility Analysis
12. As required by the Regulatory Flexibility Act of 1980, as
amended (RFA), an Initial Regulatory Flexibility Analysis (IRFA) was
incorporated in the notice of proposed rulemaking (NPRM) to this
proceeding. The Commission sought written public comment on the
proposals in the NPRM, including comment on the IRFA. The Commission
received no comments on the IRFA. This Final Regulatory Flexibility
Analysis (FRFA) conforms to the RFA.
A. Need for, and Objectives of, the Report and Order
13. This document adopts several rule changes to better reflect
current requirements and eliminate redundant, outdated, or conflicting
provisions. Specifically, the Commission:
Eliminates the maximum rated transmitter power limit rule
for AM stations. The Commission finds that an equipment limitation on
potential
[[Page 15341]]
transmitter power that is established by the transmitter manufacturer
is outdated and unnecessary given the Commission's current reliance on
actual operating antenna input power as the most accurate and effective
means of ensuring that AM stations adhere to their authorized power
limits.
Updates several rule provisions containing an obsolete
noncommercial educational (NCE) FM community of license coverage
standard to harmonize with the later-adopted, more specific, NCE
community of license coverage requirement.
Updates the signal strength contour overlap requirements
for NCE FM Class D stations to harmonize with the contour overlap
requirements for all other classes of NCE FM stations. The Commission
concludes that there is no reason to continue treating Class D stations
differently in this context and that a less preclusive standard will
create opportunities for NCE stations to increase power and coverage,
as well as provide them with greater site selection flexibility.
Eliminates the requirement for radio broadcast services to
protect grandfathered common carrier services in Alaska operating in
the 76-100 MHz frequency band. This requirement is no longer necessary
as there are no more common carriers in this band in Alaska.
Harmonizes the definition of an ``AM fill-in area'' set
out in multiple rule sections. This correction applies the most up-to-
date definition of ``AM fill-in area'' consistently across the relevant
rules.
Amends regulations applicable to broadcast stations within
320 kilometers of the Mexican and Canadian borders to implement the
most current treaty provisions.
Amending these rules to accurately reflect current requirements
will reduce potential confusion and eliminate unnecessary burdens on
broadcasters.
B. Summary of Significant Issues Raised by Public Comments in Response
to the IRFA
14. There were no comments to the IRFA filed.
C. Response to Comments by the Chief Counsel for Advocacy of the Small
Business Administration
15. Pursuant to the Small Business Jobs Act of 2010, which amended
the RFA, the Commission is required to respond to any comments filed by
the Chief Counsel for Advocacy of the Small Business Administration
(SBA), and to provide a detailed statement of any change made to the
proposed rules as a result of those comments. The Chief Counsel did not
file any comments in response to the proposed rules in this proceeding.
D. Description and Estimate of the Number of Small Entities to Which
the Rules Apply
16. The RFA directs the Commission to provide a description of and,
where feasible, an estimate of the number of small entities that will
be affected by the rules adopted herein. The RFA generally defines the
term ``small entity'' as having the same meaning as the terms ``small
business,'' ``small organization,'' and ``small government
jurisdiction.'' In addition, the term ``small business'' has the same
meaning as the term ``small business concern'' under the Small Business
Act. A small business concern is one which: (1) Is independently owned
and operated; (2) is not dominant in its field of operation; and (3)
satisfies any additional criteria established by the Small Business
Administration (SBA).
17. Radio Stations. Radio stations are an Economic Census category
that ``comprises establishments primarily engaged in broadcasting aural
programs by radio to the public. Programming may originate in their own
studio, from an affiliated network, or from external sources.'' The SBA
has established a small business size standard for this category as
firms having $41.5 million or less in annual receipts. Economic Census
data for 2012 shows that 2,849 radio station firms operated during that
year. Of that number, 2,806 operated with annual receipts of less than
$25 million per year, and 43 firms had annual receipts of $25 million
or more. Because the Census has no additional classifications that
could serve as a basis for determining the number of stations whose
receipts exceeded $41.5 million in that year, we conclude that the
majority of radio broadcast stations were small entities under the
applicable SBA size standard.
18. Apart from the U.S. Census, the Commission has estimated the
number of licensed commercial AM stations to be 4,509 and the number of
commercial FM stations to be 6,676 for a total of 11,185, along with
8,866 FM translator and booster stations. According to BIA/Kelsey
Publications, Inc.'s Media Access Pro Database, as of March 2020, 4,389
a.m. stations and 6,767 FM stations had revenues of $41.5 million or
less. In addition, the Commission has estimated the number of
noncommercial educational FM radio stations to be 4,204. NCE stations
are non-profit, and therefore considered to be small entities.
Accordingly, we estimate that the majority of radio broadcast stations
are small entities. We note, however, that, in assessing whether a
business concern qualifies as small under the above definition,
business affiliations must be included. Our estimate, therefore, likely
overstates the number of small entities that might be affected by our
action, because the revenue figure on which it is based does not
include or aggregate revenues from affiliated companies.
19. Moreover, as noted above, an element of the definition of
``small business'' is that the entity not be dominant in its field of
operation. The Commission is unable at this time to define or quantify
the criteria that would establish whether a specific radio station is
dominant in its field of operation. Accordingly, the estimate of small
businesses to which rules may apply does not exclude any radio station
from the definition of a small business on this basis and therefore may
be over-inclusive to that extent. Also, as noted, an additional element
of the definition of ``small business'' is that the entity must be
independently owned and operated. The Commission notes that it is
difficult at times to assess these criteria in the context of media
entities and the estimates of small businesses to which they apply may
be over-inclusive to this extent.
E. Description of Projected Reporting, Record Keeping and Other
Compliance Requirements
20. The rule changes adopted in the Report and Order do not include
any notification or recordkeeping requirements.
F. Steps Taken To Minimize Significant Impact on Small Entities, and
Significant Alternatives Considered
21. The RFA requires an agency to describe any significant
alternatives that it has considered in reaching its proposed approach,
which may include the following four alternatives (among others): (1)
The establishment of differing compliance or reporting requirements or
timetables that take into account the resources available to small
entities; (2) the clarification, consolidation, or simplification of
compliance or reporting requirements under the rule for small entities;
(3) the use of performance, rather than design, standards; and (4) an
exemption from coverage of the rule, or any part thereof, for small
entities.
22. The rules adopted or amended in the Report and Order do not
impose any new substantive requirements on broadcast radio stations.
Rather, they clarify existing technical requirements, create
consistency across different rules, and ensure that current treaty
terms are
[[Page 15342]]
accurately reflected in the rules. These measures will help small
entities by reducing their need to rely on third parties, such as legal
counsel, to understand the rules and comply with regulatory
requirements. Significant alternatives would include leaving the rules
as they are; however, in the Commission's judgment the increased
transparency and certainty under the amended rules would outweigh any
benefit of familiarity with the existing rules. The Commission did take
this alternative approach when it decided to retain the proximate
interference rule set out in Sec. 73.316(d), responding to industry
feedback that that rule serves a useful purpose.
G. Report to Congress
23. The Commission will send a copy of the Report and Order,
including the FRFA, in a report to Congress and the Government
Accountability Office pursuant to the Small Business Regulatory
Enforcement Fairness Act of 1996. In addition, the Commission will send
a copy of the Report and Order, including the FRFA, to the Chief
Counsel for Advocacy of the Small Business Administration. A copy of
the Report and Order and FRFA (or summaries thereof) will also be
published in the Federal Register.
Ordering Clauses
24. Accordingly, it is ordered that, pursuant to the authority
contained in Sections 1, 4(i), 4(j), 301, 303, 307, 308, 309, 316, and
319 of the Communications Act of 1934, as amended, 47 U.S.C. 151,
154(i), 154(j), 301, 303, 307, 308, 309, 316, and 319, the Report and
Order is adopted and will become effective 30 days after publication in
the Federal Register.
25. It is further ordered that parts 73 and 74 of the Commission's
Rules ARE amended as set forth in the final rules and such rule
amendments will become effective 30 days after publication in the
Federal Register.
