14 CFR Part 97

[Docket No. 30817; Amdt. No. 3456]

Standard Instrument Approach Procedures, and Takeoff Minimums and
Obstacle Departure Procedures; Miscellaneous Amendments

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This rule establishes, amends, suspends, or revokes Standard
Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums
and Obstacle Departure Procedures for operations at certain airports.
These regulatory actions are needed because of the adoption of new or
revised criteria, or because of changes occurring in the National
Airspace System, such as the commissioning of new navigational
facilities, adding new obstacles, or changing air traffic requirements.
These changes are designed to provide safe and efficient use of the
navigable airspace and to promote safe flight operations under
instrument flight rules at the affected airports.

DATES: This rule is effective December 20, 2011. The compliance date
for each SIAP, associated Takeoff Minimums, and ODP is specified in the
amendatory provisions.
    The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of December 20, 2011.

ADDRESSES: Availability of matters incorporated by reference in the
amendment is as follows:
    For examination--
    1. FAA Rules Docket, FAA Headquarters Building, 800 Independence
Avenue SW., Washington, DC 20591;
    2. The FAA Regional Office of the region in which the affected
airport is located;
    3. The National Flight Procedures Office, 6500 South MacArthur
Blvd., Oklahoma City, OK 73169 or

information on the availability of this material at NARA, call (202)
741-6030, or go to: http://www.archives.gov/federal_register/code_of_federal_regulations/ibr_locations.html.
    Availability-- All SIAPs and Takeoff Minimums and ODPs are
available online free of charge. Visit http://www.nfdc.faa.gov to
register. Additionally, individual SIAP and Takeoff Minimums and ODP
copies may be obtained from:
    1. FAA Public Inquiry Center (APA-200), FAA Headquarters Building,
800 Independence Avenue SW., Washington, DC 20591; or
    2. The FAA Regional Office of the region in which the affected
airport is located.

FOR FURTHER INFORMATION CONTACT: Richard A. Dunham III, Flight
Procedure Standards Branch (AFS-420), Flight Technologies and Programs
Divisions, Flight Standards Service, Federal Aviation Administration,
Mike Monroney Aeronautical Center, 6500 South MacArthur Blvd., Oklahoma
City, OK 73169 (Mail Address: P.O. Box 25082, Oklahoma City, OK 73125)
Telephone:<PHONE_NUMBER>.

SUPPLEMENTARY INFORMATION: This rule amends Title 14 of the Code of
Federal Regulations, part 97 (14 CFR part 97), by establishing,
amending, suspending, or revoking SIAPS, Takeoff Minimums and/or ODPS.
The complete regulators description of each SIAP and its associated
Takeoff Minimums or ODP for an identified airport is listed on FAA form
documents which are incorporated by reference in this amendment under 5
U.S.C. 552(a), 1 CFR part 51, and 14 CFR part 97.20. The applicable FAA
Forms are FAA Forms 8260-3, 8260-4, 8260-5, 8260-15A, and 8260-15B when
required by an entry on 8260-15A.
    The large number of SIAPs, Takeoff Minimums and ODPs, in addition
to their complex nature and the need for a special format make
publication in the Federal Register expensive and impractical.
Furthermore, airmen do not use the regulatory text of the SIAPs,
Takeoff Minimums or ODPs, but instead refer to their depiction on
charts printed by publishers of aeronautical materials. The advantages
of incorporation by reference are realized and publication of the
complete description of each SIAP, Takeoff Minimums and ODP listed on
FAA forms is unnecessary. This amendment provides the affected CFR
sections and specifies the types of SIAPs and the effective dates of
the, associated Takeoff Minimums and ODPs. This amendment also
identifies the airport and its location, the procedure, and the
amendment number.

The Rule

    This amendment to 14 CFR part 97 is effective upon publication of
each separate SIAP, Takeoff Minimums and ODP as contained in the
transmittal. Some SIAP and Takeoff Minimums and textual ODP amendments
may have been issued previously by the FAA in a Flight Data Center
(FDC) Notice to Airmen (NOTAM) as an emergency action of immediate
flight safety relating directly to published aeronautical charts. The
circumstances which created the need for some SIAP and Takeoff Minimums
and ODP amendments may require making them effective in less than 30
days. For the remaining SIAPS and Takeoff Minimums and ODPS, an
effective date at least 30 days after publication is provided.
    Further, the SIAPs and Takeoff Minimums and ODPS contained in this
amendment are based on the criteria contained in the U.S. Standard for
Terminal Instrument Procedures (TERPS). In developing these SIAPS and
Takeoff Minimums and ODPs, the TERPS criteria were applied to the
conditions existing or anticipated at the affected airports. Because of
the close and immediate relationship between these SIAPs, Takeoff
Minimums and ODPs, and safety in air commerce, I find that notice and
public procedures before adopting these SIAPS, Takeoff Minimums and
ODPs are impracticable and contrary to the public interest and, where
applicable, that good cause exists

for making some SIAPs effective in less than 30 days.

Conclusion

    The FAA has determined that this regulation only involves an
established body of technical regulations for which frequent and
routine amendments are necessary to keep them operationally current.
It, therefore--(1) is not a ``significant regulatory action'' under
Executive Order 12866; (2) is not a ``significant rule '' under DOT
Regulatory Policies and Procedures (44 FR 11034; February 26, 1979);
and (3) does not warrant preparation of a regulatory evaluation as the
anticipated impact is so minimal. For the same reason, the FAA
certifies that this amendment will not have a significant economic
impact on a substantial number of small entities under the criteria of
the Regulatory Flexibility Act.

SUPPLEMENTARY INFORMATION:

Background

    Section 804 of the FAA Modernization and Reform Act of 2012 (Pub.
L. 112-95) requires the FAA to develop a plan for realigning and
consolidating facilities in an effort to support the transition to
NextGen and reduce costs where such cost reductions can be implemented
without adversely affecting safety. To address Section 804
requirements, the FAA formed a collaborative workgroup of
representatives from the FAA and NATCA and PASS Labor Unions to develop
a comprehensive process to analyze different realignment and
consolidation scenarios. The collaborative process takes into account
the following factors and criteria when prioritizing facilities for
realignment analysis: NextGen readiness; the Terminal Automation
program schedule; operational and airspace factors; existing facility
conditions and workforce needs; industry stakeholder input; and the
costs and benefits associated with each potential realignment
alternative.
    In 2014, the collaborative workgroup initiated activities to
evaluate existing Terminal Radar Approach Control (TRACON) facilities
and prioritize them for annual analysis; develop an initial set of
realignment scenarios and define alternatives for each scenario;
collect facility and operational data, and document system
requirements; document facility, equipment, infrastructure, operational
and safety data; capture qualitative workforce considerations,
including training, transition, facility, and potential workforce
impacts of potential realignments; consider potential impacts on
operations, airspace modifications, route/fixes changes, arrival/
departure procedures, intra/inter-facility coordination, and aviation
community interaction; collect and consider industry stakeholder
inputs; document and quantify benefits and cost of potential
realignments; and develop a recommendation for each realignment
scenario. The recommendations for the first two scenarios analyzed by
the Section 804 collaborative workgroup are contained in the report
entitled ``FAA National Facilities Realignment and Consolidation Report
Year 1, Part 1 Recommendations,'' a copy of which has been placed in
the docket for this notice. The docket may be accessed at http://www.regulations.gov. A copy of the report has also been made available
on the FAA's Web site at http://www.faa.gov/regulations_policies/rulemaking/recently_published/.
    The realignment recommendations outlined in the Year 1 Part 1
report are the result of a collaborative process that involved a multi-
disciplinary team of FAA subject matter experts, financial analysts,
operational experts, and Labor and FAA leadership participants. The
Section 804 process serves as a stable foundation for future
realignment analyses and recommendations. The process aims to maximize
operational, administrative, and maintenance efficiencies and deliver
the highest value to stakeholders.
    The FAA is requesting comments on this report pursuant to Section
804 of the FAA Modernization and Reform Act of 2012. The agency will
consider all comments received on or before May 11, 2015. Following a
60-day comment review period, the final report along with public
comments will be submitted to Congress. The FAA continues to analyze
data collected from facilities across the United States and evaluate
possible realignment scenarios. The FAA will make its next
recommendations when it submits Part 2 of the report in mid-2015.

    Issued in Washington, DC, on March 20, 2015.

Future Facilities Group Manager.

SECURITIES AND EXCHANGE COMMISSION

[SEC File No. 270-357, OMB Control No. 3235-0404]

Submission for OMB Review Comment Request

Upon Written Request Copies Available From: Securities and Exchange
Commission, Office of FOIA Services, 100 F Street NE, Washington, DC
20549-2736

Extension:
    Form F-80

    Notice is hereby given that, pursuant to the Paperwork Reduction
Act of 1995 (44 U.S.C. 3501 et seq.), the Securities and Exchange
Commission (``Commission'') has submitted to the Office of Management
and Budget this request for extension of the previously approved
collection of information discussed below.
    Form F-80 (17 CFR 239.41) is a registration form used by large,
publicly-traded Canadian issuers to register securities that will be
offered in a business combination, exchange offer or other
reorganization requiring the vote of shareholders of the participating
companies. The information collected is intended to make available
material information upon which shareholders and investors can make
informed voting and investment decisions. The information provided is
mandatory and all information is made available to the public upon
request. Form F-80 takes approximately 2 hours per response and is
filed by approximately 4 issuers for a total annual reporting burden of
8 hours (2 hours per response x 4 responses). The estimated burden of 2
hours per response was based upon the amount of time necessary to
compile the registration statement using the existing Canadian
prospectus plus any additional information required by the Commission.
    An agency may not conduct or sponsor, and a person is not required
to respond to, a collection of information unless it displays a
currently valid control number.
    The public may view the background documentation for this
information collection at the following website, www.reginfo.gov.
Comments should be directed to: (i) Desk Officer for the Securities and
Exchange Commission, Office of Information and Regulatory Affairs,
Office of Management and Budget, Room 10102, New Executive Office
Building, Washington, DC 20503, or by sending an email to:
<EMAIL_ADDRESS>and (ii) Charles Riddle, Acting Director/
Chief Information Officer, Securities and Exchange Commission, c/o
Candace Kenner, 100 F Street NE, Washington, DC 20549 or send an email
to<EMAIL_ADDRESS>Comments must be submitted to OMB within 30
days of this notice.

    Dated: February 19, 2019.

Deputy Secretary.

DEPARTMENT OF ENERGY

Federal Energy Regulatory Commission

[Docket No. CP08-403-000]

Wyoming Interstate Company, Ltd.; Notice of Application

May 29, 2008.
    Take notice that on May 20, 2008, Wyoming Interstate Company, Ltd.
(WIC), Post Office Box 1087, Colorado Springs, Colorado 80944, filed in
the above referenced docket an application pursuant to section 7(c) of
the Natural Gas Act (NGA), and section 157.5, et seq. of the
Commission's regulations for an order granting a certificate of public
convenience to construct and operate new compression facilities, with
appurtenances, to be located in Moffat and Rio Blanco Counties,
Colorado. Referred to as the Piceance Compression Expansion Project, it
will allow WIC to transport additional volumes of natural gas from the
Piceance Basin production area in northwestern Colorado to
interconnects with various other interstate pipelines at the Opal Hub,
located in Sweetwater County, Wyoming. As part of this project, WIC is
also seeking a pre-determination of roll-in for the costs associated
with the project and the authorization for an incremental fuel charge
for the related fuel costs from the proposed facilities, all as more
fully set forth in the application which is on file with the Commission
and open to public inspection. The filing may also be viewed on the Web
at http://www.ferc.gov using the ``eLibrary'' link. Enter the docket
number excluding the last three digits in the docket number field to
access the document. For assistance, please contact FERC Online Support
at<EMAIL_ADDRESS>or toll free at<PHONE_NUMBER>, or TTY,
contact<PHONE_NUMBER>.
    Any questions concerning this application may be directed to
Richard Derryberry, Director, Regulatory Affairs, Wyoming Interstate
Company, Ltd., P.O. Box 1087, Colorado Springs, Colorado 80944 at (719)
520-3782 or by fax at<PHONE_NUMBER> or Craig V. Richardson, Vice
President and General Counsel, Wyoming Interstate Company, Ltd., P.O.
Box 1087, Colorado Springs, Colorado 80944 at<PHONE_NUMBER> or by fax
at<PHONE_NUMBER>.
    Pursuant to section 157.9 of the Commission's rules, 18 CFR 157.9,
within 90 days of this Notice the Commission staff will either:
Complete its environmental assessment (EA) and place it into the
Commission's public record (eLibrary) for this proceeding; or issue a
Notice of Schedule for Environmental Review. If a Notice of Schedule
for Environmental Review is issued, it will indicate, among other
milestones, the anticipated date for the Commission staff's issuance of
the final environmental impact statement (FEIS) or EA for this
proposal. The filing of the EA in the Commission's public record for
this proceeding or the issuance of a Notice of Schedule for
Environmental Review will serve to notify federal and state agencies of
the timing for the completion of all necessary reviews, and the
subsequent need to complete all federal authorizations within 90 days
of the date of issuance of the Commission staff's FEIS or EA.
    There are two ways to become involved in the Commission's review of
this project. First, any person wishing to obtain legal status by
becoming a party to the proceedings for this project should, on or
before the comment date stated below, file with the Federal Energy
Regulatory Commission, 888 First Street, NE., Washington, DC 20426, a
motion to intervene in accordance with the requirements of the
Commission's Rules of Practice and Procedure (18 CFR 385.214 or
385.211) and the Regulations under the NGA (18 CFR 157.10). A person
obtaining party status will be placed on the service list maintained by
the Secretary of the Commission and will receive copies of all
documents filed by the applicant and by all other parties. A party must
submit 14 copies of filings made with the Commission and must mail a
copy to the applicant and to every other party in the proceeding. Only
parties to the proceeding can ask for court review of Commission orders
in the proceeding.
    However, a person does not have to intervene in order to have
comments considered. The second way to participate is by filing with
the Secretary of the Commission, as soon as possible, an original and
two copies of comments in support of or in opposition to this project.
The Commission will consider these comments in determining the
appropriate action to be taken, but the filing of a comment alone will
not serve to make the filer a party to the proceeding. The Commission's
rules require that persons filing comments in opposition to the project
provide copies of their protests only to the party or parties directly
involved in the protest.
    Persons who wish to comment only on the environmental review of
this project should submit an original and two copies of their comments
to the Secretary of the Commission. Environmental commentors will be
placed on the Commission's environmental mailing list, will receive
copies of the environmental documents, and will be notified of meetings
associated with the Commission's environmental review process.
Environmental commentors will not be required to serve copies of filed
documents on all other parties. However, the non-party commentors will
not receive copies of all documents filed by other parties or issued by
the Commission (except for the mailing of environmental documents
issued by the Commission) and will not have the right to seek court
review of the Commission's final order.
    The Commission strongly encourages electronic filings of comments,
protests and interventions in lieu of paper using the ``eFiling'' link
at http://www.ferc.gov. Persons unable to file electronically should
submit an original and 14 copies of the protest or intervention to the
Federal Energy regulatory Commission, 888 First Street, NE.,
Washington, DC 20426.
    This filing is accessible online at http://www.ferc.gov, using the
``eLibrary'' link and is available for review in the Commission's
Public Reference Room in Washington, DC. There is an ``eSubscription''
link on the Web site that enables subscribers to receive e-mail
notification when a document is added to a subscribed docket(s). For
assistance with any FERC Online service, please e-mail
