an exemption for the B.t. Cry2Ab2
protein in or on all food and feed
commodities.
VIII. Conclusions
There is a reasonable certainty that no
harm will result from aggregate
exposure to the U.S. population,
including infants and children, to
residues of the B.t. Cry2Ab2 protein in
all food and feed commodities of
soybean. This includes all anticipated
dietary exposures and all other
exposures for which there is reliable
information. The Agency has arrived at
this conclusion because, as discussed in
this unit, no toxicity to mammals has
been observed, nor is there any
indication of allergenicity potential for
the plant-incorporated protectant.
Therefore, an exemption is
established for residues of the B.t.
Cry2Ab2 protein in or on soybean when
the protein is used as a PIP in soybean.

X. Statutory and Executive Order
Reviews
This action establishes an exemption
from the requirement of a tolerance
under FFDCA section 408(d) in
response to a petition submitted to the
Agency. The Office of Management and
Budget (OMB) has exempted these types
of actions from review under Executive
Order 12866, entitled ‘‘Regulatory
Planning and Review’’ (58 FR 51735,
October 4, 1993). Because this action
has been exempted from review under
Executive Order 12866, this action is
not subject to Executive Order 13211,
entitled ‘‘Actions Concerning
Regulations That Significantly Affect
Energy Supply, Distribution, or Use’’ (66
FR 28355, May 22, 2001), or Executive
Order 13045, entitled ‘‘Protection of

contain any information collections
subject to OMB approval under the
Paperwork Reduction Act (PRA), 44
U.S.C. 3501 et seq., nor does it require
any special considerations under
Executive Order 12898, entitled
‘‘Federal Actions to Address
Environmental Justice in Minority
Populations and Low-Income
Populations’’ (59 FR 7629, February 16,
1994).
Since tolerances and exemptions that
are established on the basis of a petition
under FFDCA section 408(d), such as
the exemption in this final rule, do not
require the issuance of a proposed rule,
the requirements of the Regulatory
Flexibility Act (RFA) (5 U.S.C. 601 et
seq.), do not apply.
This action directly regulates growers,
food processors, food handlers, and food
retailers, not States or tribes, nor does
this action alter the relationships or
distribution of power and
responsibilities established by Congress
in the preemption provisions of FFDCA
section 408(n)(4). As such, the Agency
has determined that this action will not
have a substantial direct effect on States
or tribal governments, on the
relationship between the national
government and the States or tribal
governments, or on the distribution of
power and responsibilities among the
various levels of government or between
the Federal Government and Indian
tribes. Thus, the Agency has determined
that Executive Order 13132, entitled
‘‘Federalism’’ (64 FR 43255, August 10,
1999), and Executive Order 13175,
entitled ‘‘Consultation and Coordination
with Indian Tribal Governments’’ (65 FR
67249, November 9, 2000), do not apply
to this action. In addition, this action
does not impose any enforceable duty or
contain any unfunded mandate as
described under Title II of the Unfunded
Mandates Reform Act (UMRA) (2 U.S.C.
1501 et seq.).
This action does not involve any
technical standards that would require
Agency consideration of voluntary
consensus standards pursuant to section

Introduction
Commission rules authorize Public
Safety Pool-eligible entities to use
Travelers’ Information Stations (TIS) to
transmit noncommercial, travel-related
information over AM band frequencies
to motorists on a localized basis.
§ 90.242(b)(8) of the Commission’s rules
requires the filtering of audio
frequencies between 3 and 20 kHz.
Based on a comment record indicating
that this filtering decreases the
audibility of TIS broadcasts in general,
and especially at night and over difficult
terrain, the Commission adopted a
Further Notice of Proposed Rulemaking
(FNPRM) concurrently with the Report
and Order proposing elimination of the
TIS filtering requirement. In comments
to the FNPRM, the National Association
of Broadcasters (NAB) proposed
relaxing, but not eliminating, the
filtering requirement from 3 kHz to 5
kHz. The Commission sought comment
on this proposal. The subsequent record
indicates that a relaxed filtering
VerDate Sep<11>2014
15:13 May 04, 2015
Jkt 235001
requirement could improve TIS audio
quality to match that of AM broadcast
stations, while still retaining a sufficient
filtering requirement to minimize
adjacent channel interference.
Accordingly, in this proceeding we
adopt a Second Report and Order that
maintains a filtering requirement but
relaxes it from 3 kHz to 5 kHz. We will
also do the following: (1) Require use of
a new roll-off curve to maintain the
required 50 dB attenuation at 20 kHz;
(2) allow placement of the filter ahead
of the TIS transmitter in addition to
current filter placement requirement
and; (3) require certification only for
newly manufactured equipment that
implements these new rules.
Background
The Commission established TIS in
1977 in order to ‘‘establish an efficient
means of communicating certain kinds
of information to travelers over low
power radio transmitters licensed to
Local Government entities.’’ The
Commission specifically noted that such
stations had been used to reduce traffic
congestion and to transmit ‘‘road
conditions, travel restrictions, and
weather forecasts to motorists.’’ Further,
the Commission anticipated that TIS
also would be used to ‘‘transmit travel
related emergency messages concerning
natural disasters (e.g., forest fires,
floods, etc.), traffic accidents and
hazards, and related bulletins affecting
the immediate welfare of citizens.’’
Although the NPRM did not raise the
issue of removal of the filtering
provision of § 90.242(b)(8), numerous
commenters supported it in the record.
The FNPRM thus sought further
comment on this issue in order to
establish a more complete record. The
NPRM received eleven comments (three
from the American Association of
Information Radio Operators (AAIRO))
and four reply comments (two from
AAIRO). Because NAB proposed
relaxing rather than eliminating this
requirement in its comments, and
AAIRO expressed accord with this
compromise position in its own
comments, the Commission sought
further comment on this newly raised
option in the Filtering PN.
Second Report and Order
We now consider the record in this
proceeding with respect the issues of
relaxing or eliminating the filtering
provision of § 90.242(b)(8), which
requires the filtering of TIS audio
frequencies above 3 kHz.
As noted, although the NPRM did not
raise the issue, numerous commenters
argued in the docket for removal of the
TIS filtering requirement. Commenters
PO 00000
Frm 00025
Fmt 4700
Sfmt 4700
25605
contended that this requirement
decreases the audibility of TIS
broadcasts in general, and especially at
night and over difficult terrain. One
commenter in particular, Burden, stated
that he had conducted: ‘‘An experiment
at the site of a TIS facility which had a
first adjacent [AM broadcast station]
audibly present but outside of its
protected contour. I removed the 3 kHz
filter opening the transmitted response
to that of the 8 kHz program line. The
result confirmed the intelligibility of the
transmitted signal as considerably
improved with no audible interference
presented to the reception of the first
adjacent.’’
Burden continued that: ‘‘AM
broadcast bandwidth specified by the
NRSC–2 Spectrum Mask adopted by the
FCC some time ago to resolve
interference issues, limits the audio
frequency response of AM broadcast
transmission to 10 kHz. Limiting the
bandwidth of TIS transmission to the
same bandwidth as the NRSC mask
should be logical. A recent study into
acceptable audio bandwidths conducted
by NPR Labs in an AM–DAB study for
the NRSC, concluded that limitations to
an audio bandwidth less than 7 kHz was
not advisable for AM broadcast
facilities.’’
Because this particular issue was not
raised in the NPRM but rather was
introduced by commenters in the
record, the Commission sought further
comment in the FNPRM on removing
the filtering provision, asking whether
there is any reason this restriction
should not be removed. All commenters
to the FNPRM, save two, supported
elimination of the filtering requirement.
In addition, many commenters, while
supporting this elimination, opposed a
mandate to ‘‘require filter removal for
existing licensees.’’ According to
AAIRO, ‘‘if the FCC were to mandate
that all TIS licensees who wish to
remove the filters must go through a
new type acceptance/recertification,
that requirement would present an
undue financial burden [and t]he
imposition of both the above
requirements would likely cause most
TIS Services to cease due to expense
and logistics.’’
The Society of Broadcast Engineers
(SBE) and NAB were the only
commenters opposing removal of the
TIS filtering restrictions. According to
SBE ‘‘there is a significant potential for
increased interference from this
proposal.’’ SBE took particular issue
with Burden’s claim that he ‘‘conducted
an experiment removing the ‘3 kHz filter
. . . with no audible interference
presented to the reception of the first
adjacent,’ ’’ because ‘‘[t]he commenter’s
E:\FR\FM\05MYR1.SGM

rljohnson on DSK3VPTVN1PROD with RULES
25606
Federal Register / Vol. 80, No. 86 / Tuesday, May 5, 2015 / Rules and Regulations
anecdotal experiment lacked any
demonstration of technical validity or
proper scientific methodology.’’
SBE also took issue with Burden’s
claim that ‘‘ ‘limitations to an audio
bandwidth less than 7 kHz was not
advisable for AM broadcast facilities’
and ‘it only follows that the audio
quality of the emergency message needs
to be offered with the same
intelligibility as that from AM radio
broadcast facilities’ ’’ because ‘‘[w]hat
these allegations fail to mention was
that all the standards and studies cited
were relative to AM full power
broadcast stations.’’ SBE asserts that the
findings of those studies ‘‘were not
intended to be applied to TIS stations,
which are licensed under very different
standards and with a different allocation
status.’’
SBE further alleged that ‘‘many TIS
stations fail to adhere to generally
accepted modulation standards
employed by AM broadcasters. . . . SBE
members have observed and reported
that many TIS stations grossly over- or
undermodulate their carriers resulting
in poor audio quality and/or poor
listenability. This is a . . . supervening
contributor to the poor audio quality
that they attribute incorrectly to the
audio filters.’’ While NAB shared many
of SBE’s concerns, it also submitted
‘‘that a compromise approach may be
workable.’’ Specifically, NAB stated that
‘‘a filter capable of filtering audio
frequencies above 5 kHz should allow
for a TIS signal of sufficiently higher
quality, without impeding neighboring
AM services.’’ NAB noted that ‘‘fullpower AM radio stations routinely use
5 kHz filters to address and prevent
interference among AM stations, with
few significant problems.’’ Accordingly,
NAB offered ‘‘a proposal to allow TIS
operators to use a 5 kHz filter,
presuming TIS stations broadcast only
voice content, as required under the
Commission’s rules.’’
AAIRO responded that it ‘‘can . . .
support the compromise proposed by
the National Association of
Broadcasters, . . .’’ because ‘‘[t]he wider
filter bandpass would markedly
improve TIS voice transmissions and
would also protect adjacent broadcasters
should a TIS operator transmit nonvoice material without authorization.’’
AAIRO further stated that if: A wider
bandwidth filter may be substituted in
place of the present 3-kHz filter . . . the
filter [should] be outboard to the TIS
transmitter and immediately ahead of its
audio input. The FCC should prescribe
the exact formula for the audio filter and
require its use by all TIS operations—
new or existing—whose 3-kHz filters
have been deactivated. AAIRO suggests
VerDate Sep<11>2014

Jkt 235001
Elimination Versus Relaxation of the
TIS Filtering Requirement
would prefer complete elimination of
the requirement.
The record indicates that relaxation of
the filtering requirement from 3 kHz to
5 kHz could improve TIS audio quality
and intelligibility to match that of
commercial AM broadcasting, while
still minimizing adjacent channel
interference. Even though Burden’s
experiment purported to demonstrate
that a TIS station without a filter caused
no audible adjacent channel
interference to the reception of a first
adjacent AM station outside its
protected contour, we note that it was
conducted at a single site and contains
no information about the call signs,
coordinates, power levels, or received
signal strengths of the TIS or AM
stations. Therefore, Burden’s
experiment provides us neither a
sufficient pool of results nor sufficient
data to make a general conclusion that
there would be no adjacent channel
interference anywhere were we to
entirely remove the TIS filtering
requirements. Accordingly, in this
Report and Order we adopt rules
relaxing the minimum filtering
requirement for TIS transmitters from 3
kHz to 5 kHz. We note, however, that
licensees may continue to employ the 3kHz requirement at their option.
The filtering requirement limits the
bandwidth of the TIS signal, thereby
reducing the risk of interference to the
reception of adjacent channel AM
stations. However, the rule also has the
effect of distinguishing TIS sonically
from other AM stations, so that a
motorist tuning her radio manually may
know intuitively that she has tuned to
a TIS station. Specifically, TIS stations
have smaller audio bandwidth due to
the 3-kHz filter than AM stations, so the
audio fidelity of TIS is lower and less
intelligible. Based on the record on this
filtering issue that prompted us to adopt
the FNPRM, and the record we have
developed in response to the FNPRM,
we find that the public interest benefits
of this sonic distinction are minor at
best, and that the public interest would
be better served by allowing TIS to
transmit more intelligible audio to
ensure that motorists receive and
understand travel-related information.
The Filtering PN first sought comment
on whether the public interest was
better served by relaxing the filter
requirement from 3 kHz to 5 kHz or
eliminating it as proposed in the
FNPRM. Burden still calls for complete
elimination based on his previously
discussed experiment. All the other
responding commenters support or
would accept relaxation of the filtering
requirement, although North Plainfield
Revision of Operational Requirements
The current TIS rule requires that at
audio frequencies between 3 kHz and 20
kHz, the filter ‘‘shall have an
attenuation greater than the attenuation
at 1 kHz by at least: 60 log10(f/3)
decibels, where ‘f’ is the audio
frequency in kHz.’’ At audio frequencies
above 20 kHz, the attenuation shall be
at least 50 decibels greater than the
attenuation at 1 kHz. This produces a
roll-off curve that starts at 0 dB
attenuation for 3 kHz, then increases
attenuation to approximately 50 dB at
20 kHz. In its FNPRM comments,
AAIRO suggested that the Commission
should use ‘‘the same roll-off curve
presently used in the 3-kHz filter’’ for a
5-kHz filter. However, if one slides this
curve up in frequency to have 0 dB
attenuation at 5 kHz but maintains the
same slope, then the curve would
attenuate signals only by 36 dB at 20
kHz. Accordingly, the Filtering PN
sought comment on whether 36 dB
attenuation at 20 kHz would be
sufficient or whether the roll-off curve
for a 5 kHz audio filter in a TIS system
should have 50 dB attenuation at 20
kHz, consistent with the existing rule.
The Filtering PN also noted that a rolloff curve of 83 log10(f/5) decibels for
frequencies between 5 kHz and 20 kHz
would have 0 dB attenuation at the 5
kHz starting point, and would achieve
the use of the same roll-off curve
presently used in the 3-kHz filter, as it
has proven to be adequate during the
30+ years of the TIS service’s existence.
The use of an outboard filter will
streamline the timeline to improve the
service and dramatically lower costs for
existing operators who would otherwise
be required to purchase new
transmitters or have their present
transmitters modified and recertified.’’
Because this compromise proposal
was developed in the FNPRM comment
record, the Bureau released the Filtering
PN which not only sought comment on
the issue of relaxation versus
elimination of the TIS filtering
requirement, but also whether, if the
relaxation proposal were adopted, (1)
revision of the related operational
requirements would be required; (2) the
rules regarding placement of the filter
could be revised; (3) recertification
would be required for such changes; and
(4) relaxation of the filtering
requirement (and the associated
operational changes) should be
mandatory or at the licensee’s
discretion. We address each of these
issues, below.

50 dB attenuation at 20 kHz. However,
this is a steeper roll-off curve than the
formula prescribed in the current rule.
Accordingly the Filtering PN also sought
comment on whether the Commission
should impose this attenuation if the
Commission decides to relax the
filtering requirement from 3 kHz to 5
kHz. It also sought comment on whether
affordable audio filters exist in the
marketplace that satisfy this roll-off
curve; whether equipment
manufacturers could retrofit existing
filters or economically design,
manufacture, and market such filters in
the near term; and on the general
availability of 5 kHz audio filters in the
marketplace, the roll-off curves of
specific models, and whether,
alternatively, we should impose one of
those roll-off curves in our rules.
In its Filtering PN comments, AAIRO
states that although it ‘‘suggested
previously that the same 3-kHz filtering
formula could be employed for a 5-kHz
filter for convenience of design . . . if
an alternate formula would provide
superior protection to adjacent
frequencies, it should be employed.’’
NAB too supports the Commission
requiring the proposed new roll-off
curve to achieve the required
attenuation. No commenter opposed
these proposed roll-off requirements for
use with a 5-kHz filter. Moreover, these
roll-off requirements are in the public
interest because they provide similar
interference protection to the reception
of adjacent channel AM stations as
existing 3 kHz filters based on the same
50 dB attenuation at 20 kHz. AAIRO
states that ‘‘[s]tand-alone filters that
comply with new rules for the TIS
service can be built by TIS transmitter
manufacturers, some of whom have
already committed to stand-alone filter
manufacture and to making those filters
available to the market when new
filtering rules are issued. The cost to
manufacture a passive stand-alone filter
is nominal.’’ We are persuaded that 5
kHz filters will be available for TIS at
reasonable cost. Accordingly, we adopt
these new operational requirements for
5 kHz filters in TIS systems.
Revision of the Filter Placement
Requirements
The current rule requires that ‘‘[e]ach
transmitter in a Travelers Information
Station shall be equipped with an audio
low-pass filter [that] shall be installed
between the modulation limiter and the
modulated stage.’’ However, as noted, in
response to the FNPRM, AAIRO
suggested that ‘‘the [replacement] filter
[should] be outboard to the TIS
transmitter and immediately ahead of its
audio input.’’ AAIRO further noted that
VerDate Sep<11>2014
15:13 May 04, 2015
Jkt 235001
‘‘[t]he use of an outboard filter will
streamline the timeline to improve the
service and dramatically lower costs for
existing operators who would otherwise
be required to purchase new
transmitters or have their present
transmitters modified and recertified.’’
Accordingly, the Filtering PN sought
comment on the feasibility of AAIRO’s
suggestion and whether to require such
configuration in our rules in the event
the Commission were to relax the
filtering requirement.
In its Filtering PN comments, AAIRO
reiterates that the ‘‘least burdensome
way for a willing licensee to make a
filter change is to merely ‘turn off’ the
existing 3-kHz TIS filter in the
transmitter (which can be done by
merely removing a single jumper on a
circuit board) and to add a stand-alone
5-kHz filter ahead of the transmitter in
the audio chain.’’ NAB states that the
filter should still be installed between
the modulation limiter and the
modulated stage as required by the
current rule. However, NAB also states
that it could accept an alternative: audio
processors that incorporate what it
refers to as 5 kHz ‘‘brick wall’’ filtering,
so long as those processors are
commonly accepted and approved for
the commercial AM broadcast service.
The current filter placement is at the
last stage in the audio chain before
modulation of the signal to radio
frequencies (RF). The filter placement
required in the rule ensures that any
signal distortion introduced by the
modulation limiter does not effectively
increase the bandwidth of the audio
signal before the modulation to RF.
Based on AAIRO’s description of the
filter placement, the filter is integrated
onto a circuit board and cannot be
replaced by a user. Placing a 5 kHz filter
between the modulation limiter and the
modulated stage, as NAB requests,
would effectively require a circuit board
replacement, which is essentially the
whole TIS transmitter system. However,
NAB’s alternative suggestion, an audio
processor, would replace the
modulation limiter and audio filter and
thus would also require a circuit board
replacement. The cost for TIS operators
to replace a typical TIS transmitter
would be $18–23,000 for equipment and
installation. While either of NAB’s
proposals would reduce slightly the
likelihood of harmful interference from
TIS operations to broadcast stations in
the AM band relative to an outboard
filter, neither slight improvement would
be significant enough to warrant the
associated costs that would be imposed
on TIS operators. Modulation limiters
may have the potential to introduce
some distortion into the signal after the
PO 00000

signal has passed through an outboard
5 kHz filter, but given that the
Commission will have certified all TIS
transmitter models on the market for
proper operation; that the 5-kHz filter
we prescribe has a steeper roll-off curve
than current 3-kHz filters, and that AM
radio limits the upper modulating
frequency to 5 kHz, we believe this
likely to be of only minimal concern.
We revise our TIS rules to allow for
a placement of the audio filter either
ahead of the transmitter or between the
modulation limiter and the modulated
stage. This allows for either an outboard
filter ahead of the transmitter circuit
board before the board’s modulation
limiter, or a filter integrated into the
transmitter circuit board in the present
position after the modulation limiter.
We expect our action will lead to
improved audio quality at reasonable
cost for TIS operators who wish to take
advantage of the new rules and will not
increase the potential for harmful
interference. We therefore revise our
rules to permit TIS operators to retrofit
TIS equipment equipped with 3 kHz
filters by placing the outboard 5 kHz
audio filter at the transmitter audio
input, and deactivate the 3 kHz filter, as
AAIRO recommends. Similarly, we will
allow manufacturers to manufacture,
market, and sell already certified TIS
systems that have been retrofitted
accordingly. Alternatively,
manufacturers may design new TIS
systems where the 5 kHz audio filter is
at the current placement between the
modulation limiter and the modulated
stage, or a system equipped with an
audio processor that performs the
filtering with the prescribed roll-off
performance. However, to avoid
imposing burdens on manufacturers, we
do not require any redesigns of TIS
equipment. We realize that interested
manufacturers may choose the first
option out of cost considerations, as
AAIRO observed in its comments to the
Filtering PN. We discuss the FCC
equipment certification of these
permutations below.
Certification
Many FNPRM commenters who
supported elimination of the filtering
requirement also requested that no
recertification requirement accompany
such change. The Filtering PN sought
comment on whether audio filter
elimination/replacement and AAIRO’s
foregoing suggestion regarding filter
placement would either: (1) Constitute a
change to TIS transmitters that requires
recertification; (2) constitute a
permissive change in certificated
equipment that does not require
recertification; or (3) be exempt from the

rljohnson on DSK3VPTVN1PROD with RULES
25608
Federal Register / Vol. 80, No. 86 / Tuesday, May 5, 2015 / Rules and Regulations
Commission’s equipment authorization
rules.
No commenter spoke to the question
of whether any of the foregoing changes,
i.e., raising the minimum frequency for
filtering a TIS transmitter from 3 to 5
kHz, the modification of the roll-off
curve, and replacing the filter, would
thereafter require recertification of the
equipment under the Commission’s
rules. A retrofit to already certified
equipment, i.e., the addition of an
outboard 5 kHz filter at the audio input
of equipment with ‘‘deactivated’’ 3 kHz
filters, will require a Class II permissive
change under § 2.1043(b)(2) of the
Commission’s rules, because the
performance characteristics will be
degraded from the time of the initial
certification but will still meet the
minimum requirements of the
applicable rules. In this instance,
manufacturers should file a Class II
permissive change request with the
Commission for each TIS model they
seek to have retrofitted, and each
permissive change filing should include
a list of filters, if more than one to be
approved with the system, and clear and
concise instructions for TIS operators to
perform the retrofit themselves.
Grantees should make such instructions
available to their customers and other
interested TIS operators. Licensees
interested in retrofitting existing
equipment with 5 kHz filters must
verify that their equipment model has
received a Class II permissive change
grant from the Commission and only use
approved filters for the system. Then,
such licensees may retrofit the
equipment per the manufacturer’s
instructions without further
Commission authorization.
Alternatively, if manufacturers design
new TIS transmitters that contain 5 kHz
audio filters between the modulation
limiter and the modulated stage, that is,
integrated into the circuit board, this
will require a new Commission
certification because this would
effectively require a new design, which
is essentially a whole new TIS
transmitter system. Absent a dedicated
5 kHz filter, use of an audio processor
to perform the 5 kHz filtering, including
a digital audio player as AAIRO
mentions, will require Commission
certification to operate under § 90.242 to
ensure that their output—independent
of the input frequency content—satisfies
the prescribed roll-off requirements.
Mandatory Nature of Change to
Filtering Requirement
The Filtering PN also sought comment
on whether, if the Commission either
relaxes or eliminates the TIS filtering
requirement, it should also require
VerDate Sep<11>2014
15:13 May 04, 2015
Jkt 235001
existing licensees to comply with the
relaxed filtering parameters. According
to AAIRO, the only commenter on this
issue, the ‘‘change to new filtering
requirements should be made optional
to individual licensees rather than being
mandated. Certainly, none are harmed,
if a licensee determines that s/he will
retain the present 3-kHz filter.
Mandating the change for all current TIS
operators would present a significant
financial burden to governmental
entities.’’ We find AAIRO’s arguments
persuasive on this issue. Accordingly,
we find that there is in fact no reason
to mandate that all TIS licensees replace
their 3 kHz filter since, if a licensee does
not choose to relax its own TIS
transmitter filtering parameters, there
would be no change from the present,
more stringent TIS filtering
requirements. Manufacturers may also
continue to manufacture, market, and
sell already certified TIS systems, which
have the 3 kHz filters ‘‘activated,’’ as
these systems are in compliance with
both the existing filtering rule and the
more relaxed rule we adopt today.
Music Content
Finally, SBE provided anecdotal
reports of musical content over TIS and
contends that ‘‘[w]hile most voice
content is below 3 KHz, music expands
that bandwidth.’’ However, AAIRO
asserts that ‘‘[n]one of AAIRO’s nearly
400 members ‘broadcast musical
content.’ ’’ NAB argues that music’s
wider bandwidth ‘‘may not be
adequately filtered by a 5 kHz filter and
could cause harmful interference to
neighboring AM radio services,’’ and
‘‘reiterate[s] that relaxing the TIS
filtering requirement must be contingent
on TIS stations’ strict compliance with
47 CFR 90.242(a)(7).’’ While we cannot
take enforcement action at this time
based on the limited evidence before us,
we take this opportunity to remind
licensees that only voice content is
permitted per § 90.242(a)(7) of our rules,
and that music content of any kind is
not permitted.

SUPPLEMENTARY INFORMATION:
Background
The U.S. Atlantic swordfish fishery is
managed under the 2006 Consolidated
HMS FMP. Implementing regulations at
50 CFR part 635 are issued under the
authority of the Magnuson-Stevens Act,
16 U.S.C. 1801 et seq., and ATCA, 16
U.S.C. 971 et seq. ATCA authorizes the
Secretary of Commerce (Secretary) to
promulgate regulations as may be
necessary and appropriate to implement
ICCAT recommendations.
For North Atlantic swordfish, this
final action maintains the U.S. baseline
quota of 2,937.6 metric tons (mt)
dressed weight (dw) and implements an
ICCAT-recommended quota transfer of
18.8 mt dw from the United States to
Mauritania. For South Atlantic
swordfish, this action maintains the
U.S. South Atlantic swordfish quota at
75.2 mt dw (100 mt whole weight (ww)),
carries over 75.1 mt dw of 2014
underharvest, and authorizes the
transfer of 50 mt ww (37.6 mt dw) to
ˆ
Namibia, 25 mt ww (18.8 mt dw) to Cote
d’Ivoire, and 25 mt ww (18.8 mt dw) to
Belize, consistent with ICCAT
Recommendation 13–03. Information
regarding the quota calculations can be
found below. Additional details
regarding the quotas and other actions
in this rule and their impacts can be
found in the proposed rule (80 FR 8838,
February 19, 2015).
North Atlantic Swordfish Quota
At the 2013 ICCAT annual meeting,
Recommendation 13–02 was adopted,
maintaining the North Atlantic
swordfish total allowable catch (TAC) of
10,301 metric tons (mt) dressed weight
(dw) (13,700 mt whole weight (ww))
through 2016. Of this TAC, the United
States’ baseline quota is 2,937.6 mt dw
(3,907 mt ww) per year. ICCAT
Recommendation 13–02 also includes
an 18.8 mt dw (25 mt ww) annual quota
transfer from the United States to
Mauritania and limits allowable 2014
and any future underharvest carryover
PO 00000
Frm 00029
Fmt 4700

25609
to 15 percent of a contracting party’s
baseline quota. Therefore, the United
States may carry over a maximum of
440.6 mt dw (585.9 mt ww) of
underharvest from 2014 to 2015. This
final rule adjusts the U.S. baseline quota
for the 2015 fishing year to account for
the annual quota transfer to Mauritania
and the 2014 underharvest.
The 2015 North Atlantic swordfish
baseline quota is 2,937.6 mt dw (3,907
mt ww). The preliminary estimate of
North Atlantic swordfish underharvest
for 2014 is 2,395.6 mt dw (3,186.1 mt
ww). Even without including an
estimate of dead discards, the estimated
underharvest is larger than the
maximum carryover cap (440.6 mt dw
or 585.9 mt ww). Therefore, as
proposed, NMFS is carrying forward
440.6 mt dw, the maximum carryover
allowed per Recommendation 13–02.
Additionally, this final rule reduces the
2,937.6 mt dw baseline quota by the
18.8 mt dw (25 mt ww) annual quota
transfer to Mauritania. These two
changes result in an adjusted North
Atlantic swordfish quota for the 2015
fishing year of 3,359.4 mt dw (2,937.6
baseline quota + 440.6 underharvest
¥18.8 transfer to Mauritania = 3,359.4
mt dw or 4467.47 mt ww). From that
adjusted quota, 50 mt dw is allocated to
the reserve category for in season
adjustments and research, and 300 mt
dw is allocated to the incidental
category, which includes recreational
landings and landings by incidental
swordfish permit holders, per
§ 635.27(c)(1)(i). This results in an
allocation of 3,009.4 mt dw (3,359.4
adjusted quota ¥50 to the reserve
quota—300 mt dw to the incidental
quota = 3,009.4 mt dw) for the directed
category, which is split equally between
two seasons in 2015 (January through
June, and July through December) (Table
1).
South Atlantic Swordfish Quota
In 2013, ICCAT Recommendation 13–
03 established the South Atlantic
swordfish TAC at 11,278.2 mt dw
(15,000 mt ww) for 2014, 2015, and
2016. Of this, the United States receives
75.2 mt dw (100 mt ww).
Recommendation 13–03 limits the
amount of South Atlantic swordfish
underharvest that can be carried
forward, and the United States may
carry forward up to 100 percent of its
baseline quota (75.2 mt dw).
Recommendation 13–03 also included a
total of 75.2 mt dw (100 mt ww) of
quota transfers from the United States to
other countries. These transfers were
37.6 mt dw (50 mt ww) to Namibia, 18.8
ˆ
mt dw (25 mt ww) to Cote d’Ivoire, and
18.8 mt dw (25 mt ww) to Belize.

Introduction
Commission rules authorize Public Safety Pool-eligible entities to
use Travelers' Information Stations (TIS) to transmit noncommercial,
travel-related information over AM band frequencies to motorists on a
localized basis. Sec. 90.242(b)(8) of the Commission's rules requires
the filtering of audio frequencies between 3 and 20 kHz. Based on a
comment record indicating that this filtering decreases the audibility
of TIS broadcasts in general, and especially at night and over
difficult terrain, the Commission adopted a Further Notice of Proposed
Rulemaking (FNPRM) concurrently with the Report and Order proposing
elimination of the TIS filtering requirement. In comments to the FNPRM,
the National Association of Broadcasters (NAB) proposed relaxing, but
not eliminating, the filtering requirement from 3 kHz to 5 kHz. The
Commission sought comment on this proposal. The subsequent record
indicates that a relaxed filtering requirement could improve TIS audio
quality to match that of AM broadcast stations, while still retaining a
sufficient filtering requirement to minimize adjacent channel
interference. Accordingly, in this proceeding we adopt a Second Report
and Order that maintains a filtering requirement but relaxes it from 3
kHz to 5 kHz. We will also do the following: (1) Require use of a new
roll-off curve to maintain the required 50 dB attenuation at 20 kHz;
(2) allow placement of the filter ahead of the TIS transmitter in
addition to current filter placement requirement and; (3) require
certification only for newly manufactured equipment that implements
these new rules.
Background
The Commission established TIS in 1977 in order to ``establish an
efficient means of communicating certain kinds of information to
travelers over low power radio transmitters licensed to Local
Government entities.'' The Commission specifically noted that such
stations had been used to reduce traffic congestion and to transmit
``road conditions, travel restrictions, and weather forecasts to
motorists.'' Further, the Commission anticipated that TIS also would be
used to ``transmit travel related emergency messages concerning natural
disasters (e.g., forest fires, floods, etc.), traffic accidents and
hazards, and related bulletins affecting the immediate welfare of
citizens.''
Although the NPRM did not raise the issue of removal of the
filtering provision of Sec. 90.242(b)(8), numerous commenters
supported it in the record. The FNPRM thus sought further comment on
this issue in order to establish a more complete record. The NPRM
received eleven comments (three from the American Association of
Information Radio Operators (AAIRO)) and four reply comments (two from
AAIRO). Because NAB proposed relaxing rather than eliminating this
requirement in its comments, and AAIRO expressed accord with this
compromise position in its own comments, the Commission sought further
comment on this newly raised option in the Filtering PN.
Second Report and Order
We now consider the record in this proceeding with respect the
issues of relaxing or eliminating the filtering provision of Sec.
90.242(b)(8), which requires the filtering of TIS audio frequencies
above 3 kHz.
As noted, although the NPRM did not raise the issue, numerous
commenters argued in the docket for removal of the TIS filtering
requirement. Commenters contended that this requirement decreases the
audibility of TIS broadcasts in general, and especially at night and
over difficult terrain. One commenter in particular, Burden, stated
that he had conducted: ``An experiment at the site of a TIS facility
which had a first adjacent [AM broadcast station] audibly present but
outside of its protected contour. I removed the 3 kHz filter opening
the transmitted response to that of the 8 kHz program line. The result
confirmed the intelligibility of the transmitted signal as considerably
improved with no audible interference presented to the reception of the
first adjacent.''
Burden continued that: ``AM broadcast bandwidth specified by the
NRSC-2 Spectrum Mask adopted by the FCC some time ago to resolve
interference issues, limits the audio frequency response of AM
broadcast transmission to 10 kHz. Limiting the bandwidth of TIS
transmission to the same bandwidth as the NRSC mask should be logical.
A recent study into acceptable audio bandwidths conducted by NPR Labs
in an AM-DAB study for the NRSC, concluded that limitations to an audio
bandwidth less than 7 kHz was not advisable for AM broadcast
facilities.''
Because this particular issue was not raised in the NPRM but rather
was introduced by commenters in the record, the Commission sought
further comment in the FNPRM on removing the filtering provision,
asking whether there is any reason this restriction should not be
removed. All commenters to the FNPRM, save two, supported elimination
of the filtering requirement. In addition, many commenters, while
supporting this elimination, opposed a mandate to ``require filter
removal for existing licensees.'' According to AAIRO, ``if the FCC were
to mandate that all TIS licensees who wish to remove the filters must
go through a new type acceptance/recertification, that requirement
would present an undue financial burden [and t]he imposition of both
the above requirements would likely cause most TIS Services to cease
due to expense and logistics.''
The Society of Broadcast Engineers (SBE) and NAB were the only
commenters opposing removal of the TIS filtering restrictions.
According to SBE ``there is a significant potential for increased
interference from this proposal.'' SBE took particular issue with
Burden's claim that he ``conducted an experiment removing the `3 kHz
filter . . . with no audible interference presented to the reception of
the first adjacent,' '' because ``[t]he commenter's
[[Page 25606]]
anecdotal experiment lacked any demonstration of technical validity or
proper scientific methodology.''
SBE also took issue with Burden's claim that `` `limitations to an
audio bandwidth less than 7 kHz was not advisable for AM broadcast
facilities' and `it only follows that the audio quality of the
emergency message needs to be offered with the same intelligibility as
that from AM radio broadcast facilities' '' because ``[w]hat these
allegations fail to mention was that all the standards and studies
cited were relative to AM full power broadcast stations.'' SBE asserts
that the findings of those studies ``were not intended to be applied to
TIS stations, which are licensed under very different standards and
with a different allocation status.''
SBE further alleged that ``many TIS stations fail to adhere to
generally accepted modulation standards employed by AM broadcasters. .
. . SBE members have observed and reported that many TIS stations
grossly over- or undermodulate their carriers resulting in poor audio
quality and/or poor listenability. This is a . . . supervening
contributor to the poor audio quality that they attribute incorrectly
to the audio filters.'' While NAB shared many of SBE's concerns, it
also submitted ``that a compromise approach may be workable.''
Specifically, NAB stated that ``a filter capable of filtering audio
frequencies above 5 kHz should allow for a TIS signal of sufficiently
higher quality, without impeding neighboring AM services.'' NAB noted
that ``full-power AM radio stations routinely use 5 kHz filters to
address and prevent interference among AM stations, with few
significant problems.'' Accordingly, NAB offered ``a proposal to allow
TIS operators to use a 5 kHz filter, presuming TIS stations broadcast
only voice content, as required under the Commission's rules.''
AAIRO responded that it ``can . . . support the compromise proposed
by the National Association of Broadcasters, . . .'' because ``[t]he
wider filter bandpass would markedly improve TIS voice transmissions
and would also protect adjacent broadcasters should a TIS operator
transmit non-voice material without authorization.'' AAIRO further
stated that if: A wider bandwidth filter may be substituted in place of
the present 3-kHz filter . . . the filter [should] be outboard to the
TIS transmitter and immediately ahead of its audio input. The FCC
should prescribe the exact formula for the audio filter and require its
use by all TIS operations--new or existing--whose 3-kHz filters have
been deactivated. AAIRO suggests the use of the same roll-off curve
presently used in the 3-kHz filter, as it has proven to be adequate
during the 30+ years of the TIS service's existence. The use of an
outboard filter will streamline the timeline to improve the service and
dramatically lower costs for existing operators who would otherwise be
required to purchase new transmitters or have their present
transmitters modified and recertified.''
Because this compromise proposal was developed in the FNPRM comment
record, the Bureau released the Filtering PN which not only sought
comment on the issue of relaxation versus elimination of the TIS
filtering requirement, but also whether, if the relaxation proposal
were adopted, (1) revision of the related operational requirements
would be required; (2) the rules regarding placement of the filter
could be revised; (3) recertification would be required for such
changes; and (4) relaxation of the filtering requirement (and the
associated operational changes) should be mandatory or at the
licensee's discretion. We address each of these issues, below.
Elimination Versus Relaxation of the TIS Filtering Requirement
The filtering requirement limits the bandwidth of the TIS signal,
thereby reducing the risk of interference to the reception of adjacent
channel AM stations. However, the rule also has the effect of
distinguishing TIS sonically from other AM stations, so that a motorist
tuning her radio manually may know intuitively that she has tuned to a
TIS station. Specifically, TIS stations have smaller audio bandwidth
due to the 3-kHz filter than AM stations, so the audio fidelity of TIS
is lower and less intelligible. Based on the record on this filtering
issue that prompted us to adopt the FNPRM, and the record we have
developed in response to the FNPRM, we find that the public interest
benefits of this sonic distinction are minor at best, and that the
public interest would be better served by allowing TIS to transmit more
intelligible audio to ensure that motorists receive and understand
travel-related information.
The Filtering PN first sought comment on whether the public
interest was better served by relaxing the filter requirement from 3
kHz to 5 kHz or eliminating it as proposed in the FNPRM. Burden still
calls for complete elimination based on his previously discussed
experiment. All the other responding commenters support or would accept
relaxation of the filtering requirement, although North Plainfield
would prefer complete elimination of the requirement.
The record indicates that relaxation of the filtering requirement
from 3 kHz to 5 kHz could improve TIS audio quality and intelligibility
to match that of commercial AM broadcasting, while still minimizing
adjacent channel interference. Even though Burden's experiment
purported to demonstrate that a TIS station without a filter caused no
audible adjacent channel interference to the reception of a first
adjacent AM station outside its protected contour, we note that it was
conducted at a single site and contains no information about the call
signs, coordinates, power levels, or received signal strengths of the
TIS or AM stations. Therefore, Burden's experiment provides us neither
a sufficient pool of results nor sufficient data to make a general
conclusion that there would be no adjacent channel interference
anywhere were we to entirely remove the TIS filtering requirements.
Accordingly, in this Report and Order we adopt rules relaxing the
minimum filtering requirement for TIS transmitters from 3 kHz to 5 kHz.
We note, however, that licensees may continue to employ the 3-kHz
requirement at their option.
Revision of Operational Requirements
The current TIS rule requires that at audio frequencies between 3
kHz and 20 kHz, the filter ``shall have an attenuation greater than the
attenuation at 1 kHz by at least: 60 log10(f/3) decibels, where `f' is
the audio frequency in kHz.'' At audio frequencies above 20 kHz, the
attenuation shall be at least 50 decibels greater than the attenuation
at 1 kHz. This produces a roll-off curve that starts at 0 dB
attenuation for 3 kHz, then increases attenuation to approximately 50
dB at 20 kHz. In its FNPRM comments, AAIRO suggested that the
Commission should use ``the same roll-off curve presently used in the
3-kHz filter'' for a 5-kHz filter. However, if one slides this curve up
in frequency to have 0 dB attenuation at 5 kHz but maintains the same
slope, then the curve would attenuate signals only by 36 dB at 20 kHz.
Accordingly, the Filtering PN sought comment on whether 36 dB
attenuation at 20 kHz would be sufficient or whether the roll-off curve
for a 5 kHz audio filter in a TIS system should have 50 dB attenuation
at 20 kHz, consistent with the existing rule.
The Filtering PN also noted that a roll-off curve of 83 log10(f/5)
decibels for frequencies between 5 kHz and 20 kHz would have 0 dB
attenuation at the 5 kHz starting point, and would achieve
[[Page 25607]]
50 dB attenuation at 20 kHz. However, this is a steeper roll-off curve
than the formula prescribed in the current rule. Accordingly the
Filtering PN also sought comment on whether the Commission should
impose this attenuation if the Commission decides to relax the
filtering requirement from 3 kHz to 5 kHz. It also sought comment on
whether affordable audio filters exist in the marketplace that satisfy
this roll-off curve; whether equipment manufacturers could retrofit
existing filters or economically design, manufacture, and market such
filters in the near term; and on the general availability of 5 kHz
audio filters in the marketplace, the roll-off curves of specific
models, and whether, alternatively, we should impose one of those roll-
off curves in our rules.
In its Filtering PN comments, AAIRO states that although it
``suggested previously that the same 3-kHz filtering formula could be
employed for a 5-kHz filter for convenience of design . . . if an
alternate formula would provide superior protection to adjacent
frequencies, it should be employed.'' NAB too supports the Commission
requiring the proposed new roll-off curve to achieve the required
attenuation. No commenter opposed these proposed roll-off requirements
for use with a 5-kHz filter. Moreover, these roll-off requirements are
in the public interest because they provide similar interference
protection to the reception of adjacent channel AM stations as existing
3 kHz filters based on the same 50 dB attenuation at 20 kHz. AAIRO
states that ``[s]tand-alone filters that comply with new rules for the
TIS service can be built by TIS transmitter manufacturers, some of whom
have already committed to stand-alone filter manufacture and to making
those filters available to the market when new filtering rules are
issued. The cost to manufacture a passive stand-alone filter is
nominal.'' We are persuaded that 5 kHz filters will be available for
TIS at reasonable cost. Accordingly, we adopt these new operational
requirements for 5 kHz filters in TIS systems.
Revision of the Filter Placement Requirements
The current rule requires that ``[e]ach transmitter in a Travelers
Information Station shall be equipped with an audio low-pass filter
[that] shall be installed between the modulation limiter and the
modulated stage.'' However, as noted, in response to the FNPRM, AAIRO
suggested that ``the [replacement] filter [should] be outboard to the
TIS transmitter and immediately ahead of its audio input.'' AAIRO
further noted that ``[t]he use of an outboard filter will streamline
the timeline to improve the service and dramatically lower costs for
existing operators who would otherwise be required to purchase new
transmitters or have their present transmitters modified and
recertified.'' Accordingly, the Filtering PN sought comment on the
feasibility of AAIRO's suggestion and whether to require such
configuration in our rules in the event the Commission were to relax
the filtering requirement.
In its Filtering PN comments, AAIRO reiterates that the ``least
burdensome way for a willing licensee to make a filter change is to
merely `turn off' the existing 3-kHz TIS filter in the transmitter
(which can be done by merely removing a single jumper on a circuit
board) and to add a stand-alone 5-kHz filter ahead of the transmitter
in the audio chain.'' NAB states that the filter should still be
installed between the modulation limiter and the modulated stage as
required by the current rule. However, NAB also states that it could
accept an alternative: audio processors that incorporate what it refers
to as 5 kHz ``brick wall'' filtering, so long as those processors are
commonly accepted and approved for the commercial AM broadcast service.
The current filter placement is at the last stage in the audio
chain before modulation of the signal to radio frequencies (RF). The
filter placement required in the rule ensures that any signal
distortion introduced by the modulation limiter does not effectively
increase the bandwidth of the audio signal before the modulation to RF.
Based on AAIRO's description of the filter placement, the filter is
integrated onto a circuit board and cannot be replaced by a user.
Placing a 5 kHz filter between the modulation limiter and the modulated
stage, as NAB requests, would effectively require a circuit board
replacement, which is essentially the whole TIS transmitter system.
However, NAB's alternative suggestion, an audio processor, would
replace the modulation limiter and audio filter and thus would also
require a circuit board replacement. The cost for TIS operators to
replace a typical TIS transmitter would be $18-23,000 for equipment and
installation. While either of NAB's proposals would reduce slightly the
likelihood of harmful interference from TIS operations to broadcast
stations in the AM band relative to an outboard filter, neither slight
improvement would be significant enough to warrant the associated costs
that would be imposed on TIS operators. Modulation limiters may have
the potential to introduce some distortion into the signal after the
signal has passed through an outboard 5 kHz filter, but given that the
Commission will have certified all TIS transmitter models on the market
for proper operation; that the 5-kHz filter we prescribe has a steeper
roll-off curve than current 3-kHz filters, and that AM radio limits the
upper modulating frequency to 5 kHz, we believe this likely to be of
only minimal concern.
We revise our TIS rules to allow for a placement of the audio
filter either ahead of the transmitter or between the modulation
limiter and the modulated stage. This allows for either an outboard
filter ahead of the transmitter circuit board before the board's
modulation limiter, or a filter integrated into the transmitter circuit
board in the present position after the modulation limiter. We expect
our action will lead to improved audio quality at reasonable cost for
TIS operators who wish to take advantage of the new rules and will not
increase the potential for harmful interference. We therefore revise
our rules to permit TIS operators to retrofit TIS equipment equipped
with 3 kHz filters by placing the outboard 5 kHz audio filter at the
transmitter audio input, and deactivate the 3 kHz filter, as AAIRO
recommends. Similarly, we will allow manufacturers to manufacture,
market, and sell already certified TIS systems that have been
retrofitted accordingly. Alternatively, manufacturers may design new
TIS systems where the 5 kHz audio filter is at the current placement
between the modulation limiter and the modulated stage, or a system
equipped with an audio processor that performs the filtering with the
prescribed roll-off performance. However, to avoid imposing burdens on
manufacturers, we do not require any redesigns of TIS equipment. We
realize that interested manufacturers may choose the first option out
of cost considerations, as AAIRO observed in its comments to the
Filtering PN. We discuss the FCC equipment certification of these
permutations below.
Certification
Many FNPRM commenters who supported elimination of the filtering
requirement also requested that no recertification requirement
accompany such change. The Filtering PN sought comment on whether audio
filter elimination/replacement and AAIRO's foregoing suggestion
regarding filter placement would either: (1) Constitute a change to TIS
transmitters that requires recertification; (2) constitute a permissive
change in certificated equipment that does not require recertification;
or (3) be exempt from the
[[Page 25608]]
Commission's equipment authorization rules.
No commenter spoke to the question of whether any of the foregoing
changes, i.e., raising the minimum frequency for filtering a TIS
transmitter from 3 to 5 kHz, the modification of the roll-off curve,
and replacing the filter, would thereafter require recertification of
the equipment under the Commission's rules. A retrofit to already
certified equipment, i.e., the addition of an outboard 5 kHz filter at
the audio input of equipment with ``deactivated'' 3 kHz filters, will
require a Class II permissive change under Sec. 2.1043(b)(2) of the
Commission's rules, because the performance characteristics will be
degraded from the time of the initial certification but will still meet
the minimum requirements of the applicable rules. In this instance,
manufacturers should file a Class II permissive change request with the
Commission for each TIS model they seek to have retrofitted, and each
permissive change filing should include a list of filters, if more than
one to be approved with the system, and clear and concise instructions
for TIS operators to perform the retrofit themselves. Grantees should
make such instructions available to their customers and other
interested TIS operators. Licensees interested in retrofitting existing
equipment with 5 kHz filters must verify that their equipment model has
received a Class II permissive change grant from the Commission and
only use approved filters for the system. Then, such licensees may
retrofit the equipment per the manufacturer's instructions without
further Commission authorization. Alternatively, if manufacturers
design new TIS transmitters that contain 5 kHz audio filters between
the modulation limiter and the modulated stage, that is, integrated
into the circuit board, this will require a new Commission
certification because this would effectively require a new design,
which is essentially a whole new TIS transmitter system. Absent a
dedicated 5 kHz filter, use of an audio processor to perform the 5 kHz
filtering, including a digital audio player as AAIRO mentions, will
require Commission certification to operate under Sec. 90.242 to
ensure that their output--independent of the input frequency content--
satisfies the prescribed roll-off requirements.
Mandatory Nature of Change to Filtering Requirement
The Filtering PN also sought comment on whether, if the Commission
either relaxes or eliminates the TIS filtering requirement, it should
also require existing licensees to comply with the relaxed filtering
parameters. According to AAIRO, the only commenter on this issue, the
``change to new filtering requirements should be made optional to
individual licensees rather than being mandated. Certainly, none are
harmed, if a licensee determines that s/he will retain the present 3-
kHz filter. Mandating the change for all current TIS operators would
present a significant financial burden to governmental entities.'' We
find AAIRO's arguments persuasive on this issue. Accordingly, we find
that there is in fact no reason to mandate that all TIS licensees
replace their 3 kHz filter since, if a licensee does not choose to
relax its own TIS transmitter filtering parameters, there would be no
change from the present, more stringent TIS filtering requirements.
Manufacturers may also continue to manufacture, market, and sell
already certified TIS systems, which have the 3 kHz filters
``activated,'' as these systems are in compliance with both the
existing filtering rule and the more relaxed rule we adopt today.
Music Content
Finally, SBE provided anecdotal reports of musical content over TIS
and contends that ``[w]hile most voice content is below 3 KHz, music
expands that bandwidth.'' However, AAIRO asserts that ``[n]one of
AAIRO's nearly 400 members `broadcast musical content.' '' NAB argues
that music's wider bandwidth ``may not be adequately filtered by a 5
kHz filter and could cause harmful interference to neighboring AM radio
services,'' and ``reiterate[s] that relaxing the TIS filtering
requirement must be contingent on TIS stations' strict compliance with
47 CFR 90.242(a)(7).'' While we cannot take enforcement action at this
time based on the limited evidence before us, we take this opportunity
to remind licensees that only voice content is permitted per Sec.
90.242(a)(7) of our rules, and that music content of any kind is not
permitted.
Procedural Matters
Regulatory Flexibility Analysis
As required by the Regulatory Flexibility Act of 1980, see 5 U.S.C.
603, the Commission has prepared a Final Regulatory Flexibility
Analysis (FRFA) of the possible significant economic impact on small
entities of the policies and rules addressed in this document. The FRFA
is set forth in Appendix C of the Second Report and Order. The
Commission's Consumer and Governmental Affairs Bureau, Reference
Information Center, will send a copy of the Second Report and Order,
including this FRFA, to the Chief Counsel for Advocacy of the Small

Paperwork Reduction Act Analysis
This Second Report and Order does not contain 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 burden for small
business concerns with fewer than 25 employees, pursuant to the Small
Business Paperwork Relief Act of 2002, Pub. L. 107-198, see 44 U.S.C.
3506(c)(4).
Ordering Clauses
Accordingly, it is ordered that pursuant to sections 4(i) and 303
of the Communications Act of 1934, as amended, 47 U.S.C. 154(i) and
303, that this Second Report and Order is adopted.
It is further ordered that the Commission's Consumer and
Governmental Affairs Bureau, Reference Information Center, shall send a
copy of this Second Report and Order, including the Final Regulatory
Flexibility Analysis, to the Chief Counsel for Advocacy of the Small
Business Administration.
It is further ordered that the Commission shall send a copy of this
