List of Subjects in 6 CFR Part 5
Freedom of information; Privacy.
■ For the reasons stated in the preamble,
DHS amends Chapter I of Title 6, Code
of Federal Regulations, as follows:
accounting of disclosures made from DHS/
CBP—007 Border Crossing Information
system of records to agencies (Federal, State,
Local, Tribal, Foreign, or International), in
accordance with the published routine uses.
For the accounting of these disclosures only,
the Secretary of Homeland Security has
exempted this system from the following
provisions of the Privacy Act, subject to the
limitations set forth in 5 U.S.C. 552(c)(3);
(e)(8); and (g) pursuant to 5 U.S.C. 552a(j)(2).
Additionally, for the accounting of these
disclosures only, the Secretary of Homeland
Security has exempted this system from the
following provisions of the Privacy Act,
subject to the limitations set forth in 5 U.S.C.
552(c)(3); (e)(8); and (g) pursuant to 5 U.S.C.
552a(k)(2). Further, no exemption shall be
asserted with respect to biographical or travel
information submitted by, and collected
from, a person’s travel documents or
submitted from a government computer
system to support or to validate those travel
documents. After conferring with the
appropriate component or agency, DHS may
waive applicable exemptions in appropriate
circumstances and where it would not appear
to interfere with or adversely affect the law
enforcement purposes of the systems from
which the information is recompiled or in
which it is contained. Exemptions from the
above particular subsections are justified, on
a case-by-case basis to be determined at the
time a request is made, when information in
this system or records is recompiled or is
created from information contained in other
systems of records subject to exemptions for
the following reasons:
(a) From subsection (c)(3) (Accounting for
Disclosures) because making available to a
record subject to the accounting of
disclosures from records concerning him or
her would specifically reveal any
investigative interest in the individual.
Revealing this information could reasonably
be expect to compromise ongoing efforts to
investigate a violation of U.S. law, including
investigations of a known or suspected
terrorist or criminal, or other person of
interest, by notifying the record subject that
he or she is under investigation. This
information could also permit the record’s
subject to take measures to impede the
investigation, e.g., destroy evidence,
intimidate potential witnesses, or flee the
area to avoid or impede the investigation.
(b) From subsection (e)(8) (Notice to
Individuals) because to require individual
notice of disclosure of information due to
compulsory legal process would pose an
impossible administrative burden on DHS
and other agencies and could alert the
subjects of counterterrorism or law
enforcement investigations to the fact of
those investigations when not previously
known.
ER03FE10.000</MATH>
• Retention of records should only be
in cases were there is a reasonable
suspicion of criminal or terrorist
activity;
• The retention period should be
shortened;
• Records should only be maintained
on non-U.S. Citizens; and
• Records should only be shared
pursuant to a court order.
Responses to all these
recommendations have been provided
elsewhere within this document.
Upon careful review of the submitted
public comments, having taken into
consideration public comments
resulting from this NPRM and SORN, as
well as the Department’s position on
these public comments, DHS has
determined that for the reasons stated,
it is important that the exemptions
remain in place. DHS will implement
the rulemaking as proposed.

Fisheries of the Northeastern United
States; Reporting Requirement for
Midwater Trawl Vessels Fishing in
Closed Area I
WReier-Aviles on DSKGBLS3C1PROD with RULES
AGENCY: National Marine Fisheries
Service (NMFS), National Oceanic and
Atmospheric Administration (NOAA),
Commerce.
ACTION: Final rule; effectiveness of a
collection-of-information requirement.
SUMMARY: NMFS announces approval by
the Office of Management and Budget
(OMB) of a collection-of-information
requirement contained in Northeast
(NE) Multispecies regulations for
midwater trawl herring vessels that fish
in groundfish Closed Area I (CA I). The
intent of this final rule is to implement
these additional reporting requirements.
DATES: This rule is effective March 5,
2010. The amendments to 50 CFR
648.14(r)(2)(vii) and 648.80(d)(7)(iii)(B),
published in the Federal Register on
November 2, 2009 (74 FR 56562), will
become effective on March 5, 2010.
ADDRESSES: Written comments
regarding the burden-hour estimates or
other aspects of the collection-ofinformation requirements contained in
this final rule may be submitted to the
Regional Administrator, NMFS
Northeast Region, 55 Great Republic
Drive, Gloucester, MA 01930 and by email to DavidlRostker@omb.eop.gov,
or fax to (202) 395–7285.
FOR FURTHER INFORMATION CONTACT:
Douglas Potts, Fishery Policy Analyst,
(978) 281–9341, fax (978) 281–9135.
SUPPLEMENTARY INFORMATION: A final
rule implementing modifications to the
Gulf of Maine/Georges Bank (GOM/GB)
Herring Midwater Trawl Gear Letter of
Authorization (LOA) published in the
Federal Register on November 2, 2009
(74 FR 56562). The measures contained
VerDate Nov<24>2008
14:52 Feb 02, 2010
Jkt 220001
in the rule were effective upon
publication, with the exception of new
requirements for vessel operators to
complete and submit a CA I Midwater
Trawl Released Codend Affidavit.
Because OMB approval of the CA I
Midwater Trawl Released Codend
Affidavit had not been received by the
date the final rule was published, NMFS
delayed the effective date of the
associated reporting requirements.
These reporting requirements were
detailed in the proposed rule
(September 4, 2009; 74 FR 45798), with
public comment accepted through
September 27, 2009. All comments
received on the proposed measures were
addressed in the November 2, 2009,
final rule and are not repeated here.
On January 4, 2010, OMB approved,
without change, the collection-ofinformation contained in the CA I
Midwater Trawl Released Codend
Affidavit. Accordingly, effective March
5, 2010, if a vessel issued an All Areas
and/or an Areas 2 and 3 Limited Access
Herring Permit releases a net in CA I
before the fish can be sampled by the
observer, the vessel operator must
complete and sign a CA I Midwater
Trawl Released Codend Affidavit, as
specified in §§ 648.14(r)(2)(vii) and
648.80(d)(7)(iii)(B). The CA I Midwater
Trawl Released Codend Affidavit form
includes details of where, when, and
why the net was released as well as a
good-faith estimate of both the total
weight of fish caught on that tow and
the weight of fish released (if the tow
had been partially pumped). The
completed affidavit form must be
submitted to NMFS within 48 hr of the
completion of the trip.
Under NOAA Administrative Order
205–11, 7.01, dated December 17, 1990,
the Under Secretary of Oceans and
Atmosphere has delegated to the
Assistant Administrator for Fisheries,
NOAA, the authority to sign material for
publication in the Federal Register.
Classification
There is good cause under 5 U.S.C.
§ 553(b)(B) to waive prior notice and an
opportunity for public comment on this
action, as notice and comment would be
unnecessary and contrary to the public
interest. This reporting requirement was
detailed in the September 4, 2009,
proposed rule, with public comments
accepted through September 27, 2009.
This reporting requirement was also
detailed in the November 2, 2009, final
rule, which also explained that
implementation of the requirement was
delayed pending OMB approval of the
form. Therefore, the public has
previously been provided with notice of
this measure and opportunity to
PO 00000
Frm 00012
Fmt 4700
Sfmt 4700
comment. Providing additional notice
and comment would further delay the
collection of bycatch discard
information. The time required for
additional notice and public comment
would likely delay the implementation
of this reporting requirement past the
period in early spring when midwater
trawl vessels have historically fished in
Closed Area I. If this reporting
requirement were not in place by that
time, valuable information on bycatch
discard would not be collected. The
New England Fishery Management
Council has expressed an interest in
using data collected under this program
in the current development of
Amendment 5 to the FMP.
This final rule has been determined to
be not significant for purposes of
Executive Order 12866.
This final rule contains a new
collection-of-information requirement
subject to the Paperwork Reduction Act
(PRA). The new collection-ofinformation requirement pertaining to
the CA I Midwater Trawl Released
Codend Affidavit has been approved by
OMB under OMB control number 0648–
0602. Public reporting burden for these
requirements is estimated to average 5
min per response, including the time for
reviewing instructions, searching
existing data sources, gathering and
maintaining the data needed, and
completing and reviewing the collection
of information.
Send comments regarding these
burden estimates or any other aspect of
this data collection, including
suggestions for reducing the burden, to
NMFS at the ADDRESSES above, and email to DavidlRostker@omb.eop.gov,
or fax to (202) 395–7285.
Notwithstanding any other provision
of the law, no person is required to
respond to, and no person shall be
subject to penalty for failure to comply
with, a collection of information subject
to the requirements of the PRA, unless
that collection of information displays a
currently valid OMB control number.
