SECURITIES AND EXCHANGE COMMISSION

Sunshine Act Meetings

TIME AND DATE: Notice is hereby given, pursuant to the provisions of
the Government in the Sunshine Act, Public Law 94-409, that the
Securities and Exchange Commission will hold an Open Meeting on
Wednesday, December 14, 2022 at 10:00 a.m.

PLACE: The meeting will be webcast on the Commission's website at
www.sec.gov.

STATUS: This meeting will begin at 10:00 a.m. (ET) and will be open to
the public via webcast on the Commission's website at www.sec.gov.

MATTERS TO BE CONSIDERED:
    1. The Commission will consider whether to adopt amendments to Rule
10b5-1 under the Securities Exchange Act, and new disclosure regarding
Rule 10b5-1 trading arrangements and insider trading policies and
procedures, as well as amendments regarding the disclosure of the
timing of certain equity compensation awards and reporting of gifts on
Form 4.
    2. The Commission will consider whether to propose rule amendments
to update the disclosure required by Rule 605 under Regulation NMS of
the Securities Exchange Act of 1934 for order executions in national
market system stocks. The proposed rule amendments would expand the
scope of entities subject to Rule 605, modify the information required
to be reported under the rule, and change how orders are categorized
for purposes of the rule.
    3. The Commission will consider whether to propose amendments to
certain rules under Regulation NMS of the Securities Exchange Act of
1934 to adopt variable minimum pricing increments for the quoting and
trading of NMS stocks, reduce access fee caps, and enhance the
transparency of better priced orders.
    4. The Commission will consider whether to propose a new rule under
Regulation NMS of the Securities Exchange Act of 1934 titled the Order
Competition Rule, which would require certain equity orders of retail
investors to be exposed to competition in fair and open auctions before
such orders could be executed internally by any trading center that
restricts order-by-order competition.
    5. The Commission will consider whether to propose new rules under
the Securities Exchange Act of 1934 titled Regulation Best Execution,
which would establish a best execution standard and require detailed
policies and procedures for brokers, dealers, government securities
brokers, government securities dealers, and municipal securities
dealers and more robust policies and procedures for entities engaging
in certain conflicted transactions with retail customers, as well as
related review and documentation requirements.

BILLING CODE 4910-13-P


Laboratory Assessment of Potential Impacts to Dungeness Crabs from
Disposal of Dredged Material from the Columbia River.  Pacific Northwest
National Laboratory, Richland, WA.

 Pursuant to the Ocean Dumping Regulations at 40 CFR § 227.13(b),
dredged material which meets the following criteria is environmentally
acceptable for ocean dumping without further testing:  (1) dredged
material composed primarily of sand, gravel, rock, or any other
naturally occurring bottom material with particle sizes larges than
silt, and the material is found in areas of high current or wave energy
such as streams with large bed loads, or coastal areas with shifting
bars and channels; or (2) dredged material for beach nourishment or
restoration and is composed primarily of sand, gravel, or shell with
particle sizes compatible with material on the receiving beaches; or (3)
when the material is substantially the same as the substrate at the
proposed disposal site and the site from which the material is taken is
far removed from known existing and historical sources of pollution such
that there is a reasonable assurance that the material has not been
contaminated by such pollution.  The use of the SEF screening levels
provides an additional safeguard for material that would otherwise meet
the regulatory criteria for environmentally acceptable material for
ocean dumping without further testing.

DEPARTMENT OF TRANSPORTATION

Federal Motor Carrier Safety Administration

[Docket No. FMCSA-2022-0236]

Agency Information Collection Activities; Renewal of Currently
Approved Information Collection: Hazardous Materials Safety Permits

AGENCY: Federal Motor Carrier Safety Administration (FMCSA), Department
of Transportation (DOT).

ACTION: Notice and request for comments.

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

SUMMARY: In accordance with the Paperwork Reduction Act of 1995, FMCSA
announces its plan to submit the Information Collection Request (ICR)
described below to the Office of Management and Budget (OMB) for review
and approval and invites the public to comment. FMCSA is seeking to
renew an existing ICR titled, ``Hazardous Materials Safety Permits.''
This ICR requires companies holding safety permits to develop
communication plans that allow for the periodic tracking of hazardous
materials shipments. A record of the communications that includes the
time of the call and location of the shipment may be kept by either the
driver (e.g., recorded in the logbook) or the company. These records
must be kept, either physically or electronically, for at least 6
months at the company's principal place of business or readily
available to the employees at the principal place of business. This ICR
has been updated only to the extent that the number of motor carriers
with an active Hazardous Materials (HM) Safety Permit has increased
from 987 to 1065.

DATES: Comments on this notice must be received on or before July 10,
2023.

ADDRESSES: Written comments and recommendations for the proposed
information collection should be sent within 30 days of publication of
this notice to www.reginfo.gov/public/do/PRAMain. Find this information
collection by selecting ``Currently under 30-day Review--Open for
Public Comments'' or by using the search function.

FOR FURTHER INFORMATION CONTACT: Ms. Melissa Williams, Office of
Safety, Hazardous Materials Division, DOT, FMCSA, 6th Floor, West
Building, 1200 New Jersey Avenue SE, Washington, DC 20590-0001; 202-
366-4163; [email protected].

SUPPLEMENTARY INFORMATION:
    Title: Hazardous Materials Safety Permits.
    OMB Control Number: 2126-0030.
    Type of Request: Renewal of a currently approved information
collection.
    Respondents: Motor Carriers subject to the Hazardous Materials
Safety Permit requirements in 49 CFR part 385, subpart E.
    Estimated Number of Respondents: 1065.
    Estimated Time per Response: 5 minutes. The communication between
motor carriers and their drivers must take place at least two times per
day. It is estimated that it will take 5 minutes to maintain a daily
communication record for each driver.
    Expiration Date: September 30, 2023.
    Frequency of Response: On occasion.
    Estimated Total Annual Burden: 750,000 hours [9 million trips x 5
minutes per record / 60 minutes per hour = 750,000, rounded to the
nearest thousand].
    Background: The Secretary of Transportation is responsible for
implementing regulations to issue safety permits for transporting
certain HM in accordance with 49 U.S.C. 5101 et seq. The HM Safety
Permit regulations (49 CFR part 385, subpart E) require initial or
first time HM Safety Permit carriers to file the Unified Registration
System Form MCSA-1. Update and renewal applications must be filed with
FMCSA using the ``Combined Motor Carrier Identification Report and HM
Permit Application'' (Form MCS-150B). The HM Safety Permit regulations
also require carriers to have a security program. As part of the HM
Safety Permit regulations, carriers are required to develop and
maintain route plans so that law enforcement officials can verify the
correct location of the HM shipment. FMCSA requires companies holding
permits to develop a communications plan that allows for the periodic
tracking of the shipment. This information covers the record of
communications that includes the time of the call and location of the
shipment. The records may be kept by either the driver (e.g., recorded
in the logbook) or the company. These records must be kept, either
physically or electronically, for at least 6 months at the company's
principal place of business or be readily available to employees at the
company's principal place of business.
    Public Comments Invited: You are asked to comment on any aspect of
this information collection, including: (1) whether the proposed
collection is necessary for the performance of FMCSA's functions; (2)
the accuracy of the estimated burden; (3) ways for FMCSA to enhance the
quality, usefulness, and clarity of the collected information; and (4)
ways that the burden could be minimized without reducing the quality of
the collected information.

SUPPLEMENTARY INFORMATION:

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to Umlaut Engineering GmbH
(previously P3 Engineering GmbH) fire extinguisher part numbers (P/Ns)
P3APP003010A and P3APP003010C with a manufacturing date of March 2019
through July 2019 inclusive and with a serial number (S/N) listed in
Appendix 1 of Umlaut Vendor Service Bulletin Doc. No. P3VSB000001,
Issue C, dated December 13, 2019 (VSB P3VSB000001, Issue C), that may
be installed on various model helicopters. The NPRM published in the
Federal Register on October 8, 2021 (86 FR 56232). In the NPRM, the FAA
proposed to require removing affected fire extinguishers from service
and prohibit installing affected fire extinguishers on any aircraft.
    The NPRM was prompted by EASA AD 2020-0013, dated January 29, 2020
(EASA AD 2020-0013), issued by EASA, which is the Technical Agent for
the Member States of the European Union, to correct an unsafe condition
for Airbus Helicopters Model AS 332 C, C1, L, L1, and L2, AS 365 N2 and
N3, EC 155 B and B1, EC 175 B, EC 225 LP, SA 330 J, and SA 365 C1, C2,
C3, N, and N1 helicopters; Airbus Helicopters Deutschland GmbH Model
EC135 P1, P2, P2+, P3, T1, T2, T2+, and T3, EC635 P2+, P3, T1, T2+, and
T3, and MBB-BK117 A-1, A-3, A-4, B-1, B-2, C-1, C-2, and D-2
helicopters; Leonardo S.p.A. Model AB139, AB 204B, AB 205 A-1, AB 212,
AB 412, AB 412EP, AS-61N, AS-61N1, AW139, AW169, and AW189 helicopters;
and WSK PZL-SWIDNIK S.A. Model PZL W-3A and PZL W-3AS helicopters. EASA
advises of occurrences that have been reported of a quality issue on
certain fire extinguishers, manufactured by Umlaut Engineering GmbH
(formerly P3 Engineering GmbH), where the spindle geometries of the
extinguishers were found to be out of tolerance. The manufacturing
defect was identified in certain serial-numbered fire extinguisher P/Ns
P3APP003010A and P3APP003010C with a manufacturing date of March 2019
through July 2019 inclusive, where prolonged exposure (12 hours or
more) to high temperature conditions of more than 68 [deg]C (154.4
[deg]F) could cause a non-detectable seizure of the spindle that could
cause the fire extinguisher to be inoperative. This condition, if not
addressed, could prevent proper extinguishing of a fire in the cabin,
possibly resulting in damage to the helicopter and injury to the
occupants.
    Accordingly, EASA AD 2020-0013 requires replacing affected fire
extinguishers and prohibits installing an affected fire extinguisher on
any helicopter.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from one commenter; Net Jets. Net Jets
commented that there is a more recent revision of the service
information. The following presents the comments received on the NPRM
and the FAA's response to each comment.

Comment Regarding Updated Service Information

    Net Jets stated that VSB P3VSB000001, Issue C, which is cited in
the applicability paragraph of the NPRM, has been revised to Umlaut
Vendor Service Bulletin Doc. No. P3VSB000001, Issue D, dated September
9, 2020 (VSB P3VSB000001, Issue D), and that it adds S/Ns.
    Although Net Jets did not request any changes to the NPRM, the FAA
infers that Net Jets would like the FAA to update the required service
information (VSB P3VSB000001, Issue C), which is required to use to
identify an affected fire extinguisher as proposed in the applicability
paragraph of the NPRM, to VSB P3VSB000001, Issue D. The FAA reviewed
VSB P3VSB000001, Issue D, and while it updates certain information,
there are no changes to the S/Ns identified in its Appendix 1. In light
of this, the FAA has determined to allow the use of VSB P3VSB000001,
Issue C, or VSB P3VSB000001, Issue D, in the applicability paragraph of
this final rule.

Conclusion

    These products have been approved by EASA and are approved for
operation in the United States. Pursuant to the FAA's bilateral
agreement with the European Union, EASA has notified the FAA about the
unsafe condition described in its AD. The FAA reviewed the relevant
data, considered the comments received, and determined that air safety
requires adopting this AD as proposed. Accordingly, the FAA is issuing
this AD to address the unsafe condition on these products. Except for
minor editorial changes, and any other changes described previously,
this AD is adopted as proposed in the NPRM. None of the changes will
increase the economic burden on any operator.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed VSB P3VSB000001, Issue C, which specifies
procedures for identifying P3HAFEX fire extinguisher P/Ns P3APP003010A
and P3APP003010C, with a date of manufacture between March 2019 through
July 2019, and an S/N listed in its Appendix 1, to determine if the
fire extinguisher should be replaced. VSB P3VSB000001, Issue C, also
specifies procedures for removing, installing, and tracking affected
P3HAFEX fire extinguishers.
    The FAA also reviewed VSB P3VSB000001, Issue D, which specifies the
same procedures as VSB P3VSB000001, Issue C, except VSB

P3VSB000001, Issue D, updates Component Maintenance Manual (CMM)
references and material information.
    This material is reasonably available because the interested
parties have access to it through their normal course of business or by
the means identified in the ADDRESSES section.

Differences Between This AD and the EASA AD

    EASA AD 2020-0013 is issued against various model helicopters and
defines an affected part, whereas this AD is an appliance AD action
against affected fire extinguishers because the unsafe condition exists
in the appliance itself and not in the installation of the appliance on
certain aircraft. EASA AD 2020-0013 identifies some helicopter models
that are affected by this unsafe condition that are not identified as
possibly affected in this AD because those model helicopters are not
FAA type-certificated.

Costs of Compliance

    The FAA estimates that this AD affects 762 helicopters of U.S.
Registry. Labor rates are estimated at $85 per work-hour. Based on
these numbers, the FAA estimates that operators may incur the following
costs in order to comply with this AD.
    Replacing a fire extinguisher takes about 0.25 work-hour and parts
cost about $1,200 for an estimated cost of $1,221 per fire
extinguisher.
    According to Umlaut Engineering GmbH service information, some of
the costs of this AD may be covered under warranty, thereby reducing
the cost impact on affected individuals. The FAA does not control
warranty coverage by Umlaut Engineering GmbH; accordingly, all costs
are included in this cost estimate.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
    The FAA is issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: General requirements.
Under that section, Congress charges the FAA with promoting safe flight
of civil aircraft in air commerce by prescribing regulations for
practices, methods, and procedures the Administrator finds necessary
for safety in air commerce. This regulation is within the scope of that
authority because it addresses an unsafe condition that is likely to
exist or develop on products identified in this rulemaking action.

Regulatory Findings

    This AD will not have federalism implications under Executive Order
13132. This AD will not have a substantial direct effect on the States,
on the relationship between the national government and the States, or
on the distribution of power and responsibilities among the various
levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive
Order 12866,
    (2) Will not affect intrastate aviation in Alaska, and
    (3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
