SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-62337; File No. SR-CBOE-2010-056]

Self-Regulatory Organizations; Chicago Board Options Exchange,
Incorporated; Notice of Filing of a Proposed Rule Change Related to the
CBSX Clearly Erroneous Policy

June 21, 2010.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934
(the ``Act''),\1\ and Rule 19b-4 thereunder,\2\ notice is hereby given
that on June 18, 2010, the Chicago Board Options Exchange, Incorporated
(the ``Exchange'' or ``CBOE'') filed with the Securities and Exchange
Commission (the ``Commission'') the proposed rule change as described
in Items I, II, and III below, which Items have been prepared by the
Exchange. The Commission is publishing this notice to solicit comments
on the proposed rule change from interested persons.
---------------------------------------------------------------------------

    \2\ 17 CFR 240.19b-4.
---------------------------------------------------------------------------

I. Self-Regulatory Organization's Statement of the Terms of Substance
of the Proposed Rule Change

    The Exchange is proposing to amend CBOE Stock Exchange's (``CBSX'',
the CBOE's stock trading facility) clearly erroneous policy . The text
of the proposed rule change is available on the Exchange's Web site
(http://www.cboe.org/Legal), at the Office of the Secretary, CBOE and
at the Commission.

II. Self-Regulatory Organization's Statement of the Purpose of, and
Statutory Basis for, the Proposed Rule Change

    In its filing with the Commission, the self-regulatory organization
included statements concerning the purpose of and basis for the
proposed rule change and discussed any comments it received on the
proposed rule change. The text of those statements may be examined at
the places specified in Item IV below. The Exchange has prepared
summaries, set forth in sections A, B, and C below, of the most
significant parts of such statements.

A. Self-Regulatory Organization's Statement of the Purpose of, and
Statutory Basis for, the Proposed Rule Change

1. Purpose
    The Exchange is proposing modifications to its Rule 52.4, entitled
``Clearly Erroneous Executions.'' First, the Exchange proposes
replacing

existing paragraph (c)(2) of Rule 52.4, entitled ``Unusual
Circumstances and Joint Market Rulings'' with a new paragraph, entitled
``Multi-Stock Events Involving Twenty or More Securities.'' Second, the
Exchange proposes replacing existing paragraph (c)(4) of Rule 52.4,
entitled ``Numerical Guidelines Applicable to Volatile Market Opens''
with a new paragraph, entitled ``Individual Stock Trading Pauses.''
Third, the Exchange is proposing changes to existing paragraphs (f) and
(g) of Rule 52.4 to eliminate the ability of the Exchange to deviate
from the Numerical Guidelines contained in paragraph (c)(1) (other than
under limited circumstances set forth in paragraph (f)) when deciding
which transactions will be reviewed by the Exchange as potentially
clearly erroneous. Finally, the Exchange proposes modifications to
paragraphs (c)(1), (c)(3) and (e) of Rule 52.4 consistent with the
proposed changes to paragraphs (c)(2) and (c)(4). As proposed, the
provisions of paragraphs (c), (e)(2), (f), and (g) of Rule 52.4, as
amended pursuant to this filing, would be in effect during a pilot
period set to end on December 10, 2010. If the pilot is not either
extended or approved permanent by December 10, 2010, the prior versions
of paragraphs (c), (e)(2), (f), and (g) of Rule 52.4 would be in
effect.
    The Exchange is proposing the rule changes described below in
consultation with other markets and Commission staff to provide for
uniform treatment: (i) Of clearly erroneous execution reviews in Multi-
Stock Events involving twenty or more securities; and (ii) in the event
transactions occur that result in the issuance of an individual stock
trading pause by the primary market and subsequent transactions that
occur before the trading pause is in effect on the Exchange. The
Exchange has also proposed additional changes to Rule 52.4 that reduce
the ability of the Exchange to deviate from the objective standards set
forth in the Rule. The proposed changes are described in further detail
below.
    Revised Paragraph (c)(2) Related to Multi-Stock Events Involving
Twenty or More Securities
    The Exchange proposes to eliminate the majority of existing
paragraph (c)(2), which provides flexibility to the Exchange to use
different Numerical Guidelines or Reference Prices in various ``Unusual
Circumstances.'' The Exchange proposes to replace this paragraph with
new language that would apply to Multi-Stock Events involving twenty or
more securities whose executions occurred within a period of five
minutes or less. The revised paragraph would retain language making
clear that during Multi-Stock Events involving twenty or more
securities the number of affected transactions may be such that
immediate finality is necessary to maintain a fair and orderly market
and to protect investors and the public interest. Accordingly, in such
circumstances, decisions made by the Exchange in consultation with
other markets could not be appealed. Further, as proposed, in
connection with reviews of Multi-Stock Events involving twenty or more
securities, the Exchange may use a Reference Price other than the
consolidated last sale in its review of potentially clearly erroneous
executions. With the exception of those securities under review that
are subject to an individual stock trading pause as described in
proposed paragraph (c)(4), and to ensure consistent application across
market centers when proposed paragraph (c)(2) is invoked, the Exchange
will promptly coordinate with the other market centers to determine the
appropriate review period, which may be greater than the period of five
minutes or less that triggered application of proposed paragraph
(c)(2), as well as select one or more specific points in time prior to
the transactions in question and use transaction prices at or
immediately prior to the one or more specific points in time selected
as the Reference Price. The Exchange will nullify as clearly erroneous
all transactions that are at prices equal to or greater than 30% away
from the Reference Price in each affected security during the review
period selected by the Exchange and other markets consistent with the
proposed paragraph (c)(2).
    Because the Exchange and other market centers are adopting a
different threshold and standards to handle large-scale market events,
which would include events occurring during times of high volatility at
the beginning of regular trading hours, the Exchange proposes deletion
of paragraph (c)(4) (``Numerical Guidelines Applicable to Volatile
Market Opens'') of the existing rule. The Exchange believes that this
provision is no longer necessary, and if maintained, could result in
extremely high Numerical Guidelines (up to 90%) in certain
circumstances.
    Revised Paragraph (c)(4) Related to Individual Stock Trading Pauses
    The primary listing markets for U.S. stocks recently amended their
rules so that they may, from time to time, issue a trading pause for an
individual security if the price of such security moves 10% or more
from a sale in a preceding five-minute period. In this regard, the
Exchange recently amended its rules to halt/pause trading in an
individual stock when the primary listing market for such stock issues
a trading pause in any Circuit Breaker Stocks, as defined in
Interpretation and Policy .03 of Rule 6.3C.\3\ As described above, the
Exchange is proposing to eliminate existing paragraph (c)(4)
(``Numerical Guidelines Applicable to Volatile Market Opens''). The
Exchange proposes adopting a rule, numbered as (c)(4) following such
elimination, which will provide for uniform treatment of clearly
erroneous execution reviews in the event transactions occur that result
in the issuance of an individual stock trading pause by the primary
listing market and subsequent transactions that occur before the
trading pause is in effect on the Exchange. The proposed rule change is
necessary to provide greater certainty of the clearly erroneous
Reference Price for transactions that trigger a trading pause (the
``Trigger Trade'') and subsequent transactions occurring between the
time of the Trigger Trade and the time the trading pause message is
received by the Exchange from the single plan processor responsible for
consolidation and dissemination of information for the security and put
into effect on the Exchange, especially under highly volatile and
active market conditions.
---------------------------------------------------------------------------

    \3\ See Rule 6.3C; see also Securities Exchange Act Release No.
62252 (June 10, 2010), 75 FR 34186 (June 16, 2010) (SR-CBOE-2010-
047).
---------------------------------------------------------------------------

    The Exchange proposes to revise paragraph (c)(4) of Rule 52.4 to
allow the Exchange to use the price that triggered a trading pause in
an individual stock (the ``Trading Pause Trigger Price'') as the
Reference Price for clearly erroneous execution reviews of a Trigger
Trade and transactions that occur immediately after a Trigger Trade but
before a trading pause is in effect on the Exchange. As proposed, the
phrase ``Trading Pause Trigger Price'' shall mean the price that
triggered a trading pause in any Circuit Breaker Stocks as defined in
Interpretation and Policy .03 of Rule 6.3C. The Trading Pause Trigger
Price reflects a price calculated by the primary listing market over a
rolling five-minute period and may differ from the execution price of a
transaction that triggered a trading pause. The Exchange will rely on
the primary listing market that issued an individual stock trading
pause to determine and communicate the Trading Pause Trigger Price for
such stock. The Exchange proposes to make clear in the text that the
proposed standards in paragraph (c)(4) apply regardless of whether the
security at

issue is part of a Multi-Stock Event involving five or more securities
as described in proposed paragraphs (c)(1) and (c)(2).
    As proposed, the Numerical Guidelines set forth in Rule 52.4(c)(1),
other than those Numerical Guidelines applicable to Multi-Stock Events,
would apply to reviews of Trigger Trades and subsequent transactions.
The Exchange proposes to review, on its own motion pursuant to
paragraph (g) of the Rule, all transactions that trigger a trading
pause and subsequent transactions occurring before the trading pause is
in effect on the Exchange. The Exchange has proposed to limit such
reviews to reviews of transactions that executed at a price lower than
the Trading Pause Trigger Price in the event of a price decline and
higher than the Trading Pause Trigger Price in the event of a price
rise. Because the proposed rules for trading pauses would only apply
within Regular Trading Hours,\4\ an execution would be reviewed and
nullified as clearly erroneous if it exceeds the following thresholds:
---------------------------------------------------------------------------

    \4\ Regular Trading Hours are defined in Rule 51.2 as the time
between 8:30 a.m. and 3 p.m. Central Time. According to the rules of
the primary listing markets, an individual stock trading pause can
be issued based on a Trigger Trade that occurs at any time between
8:45 a.m. and 2:35 p.m. Central Time. See NASDAQ Rule 4120(a)(11),
NYSE Rule 80C, and NYSE Arca Rule 7.11.

                                          2x).
------------------------------------------------------------------------

    Revisions to Paragraphs (f) and (g)
    Consistent with other proposals made in this filing, the Exchange
proposes modifying paragraphs (f) and (g) to eliminate the ability of
an Exchange official to deviate from the Numerical Guidelines contained
in the Rule other than under very limited circumstances set forth in
paragraph (f).
    Current paragraph (f) provides that an Official \5\ of this
Exchange has the ability, on his or her own motion, to review and rule
on executions that result from ``any disruption or a malfunction in the
use or operation of any electronic communications and trading
facilities of CBSX, or extraordinary market conditions or other
circumstances in which the nullification of transactions may be
necessary for the maintenance of a fair and orderly market or the
protection of investors and the public interest exist * * * ''. Without
modification, the language ``extraordinary market conditions or other
circumstances * * * '' would leave the Exchange with broad discretion
to deviate from the Numerical Guidelines set forth in paragraph (c)(1).
Thus, the Exchange proposes narrowing the scope of paragraph (f) so
that it only permits the Exchange to nullify transactions consistent
with that paragraph (including at a lower Numerical Guideline) if there
is a disruption or malfunction in the operation of the Exchange's
system. For the same reason, the Exchange proposes eliminating the
words ``use or'' from the language in paragraph (f) to make clear that
the provision only applies to a disruption or malfunction of the
Exchange's system (and not of an Exchange user's systems).
---------------------------------------------------------------------------

    \5\ For purposes of Rule 52.4, an ``Official'' is defined as one
or more senior level officials of CBSX designated by the President.
See Rule 52.4(b).
---------------------------------------------------------------------------

    Paragraph (g) gives an Official of the Exchange the ability, on his
or her own motion, to review transactions as potentially clearly
erroneous. Consistent with the goal of achieving more objective and
standard results, the Exchange proposes deleting language in existing
paragraph (g) that would allow the Exchange to deviate from the
Numerical Guidelines contained in paragraph (c)(1). In addition, the
Exchange proposes to make clear that any Official of the Exchange
reviewing transactions on his or her own motion must follow the
guidelines set forth in proposed paragraph (c)(4), if applicable.
Accordingly, the Exchange proposes to modify paragraph (g) to state
that an officer must rely on paragraphs (c)(1)-(4) of Rule 52.4 when
reviewing transactions on his or her own motion.
    Additional Conforming Revisions to Paragraphs (c)(1), (c)(3) and
(e)
    Based on proposed paragraph (c)(2), the Exchange has proposed
certain conforming changes to paragraphs (c)(1), (c)(3) and (e) of the
existing Rule, as described below.
    Under current Rule 52.4, a transaction may be found to be clearly
erroneous only if the price of the transaction to buy (sell) that is
the subject of the complaint is greater than (less than) the Reference
Price by an amount that equals or exceeds the Numerical Guidelines set
forth in paragraph (c)(1) of the Rule. The ``Reference Price'' is
currently defined as ``the consolidated last sale immediately prior to
the execution(s) under review except for in Unusual Circumstances as
described in paragraph (c)(2)'' of Rule 53.4. The Exchange proposes
modifying paragraph (c)(1) consistent with the changes described above
such that the Exchange shall use the consolidated last sale immediately
prior to the execution(s) under review as the Reference Price except
for: (i) Multi-Stock Events involving twenty or more securities, as
described in proposed paragraph (c)(2); (ii) transactions not involving
a Multi-Stock Event as described in proposed paragraph (c)(2) that
trigger a trading pause and subsequent transactions, as described in
proposed paragraph (c)(4), in which case the Reference Price shall be
determined in accordance with that paragraph (c)(4); and (iii) in other
circumstances, such as, for example, relevant news impacting a security
or securities, periods of extreme market volatility, sustained
illiquidity, or widespread system issues, where use of a different
Reference Price is necessary for the maintenance of a fair and orderly
market and the protection of investors and the public interest. The
Exchange also proposes modifying paragraph (c)(1) to reduce uncertainty
as to the applicability of the Numerical Guidelines, by requiring a
finding that an execution was clearly erroneous if such execution
exceeds the Numerical Guidelines, subject only to the Additional
Factors included in paragraph (c)(3). Moreover, the Exchange proposes
revising the existing description for Multi-Stock Events that is
contained on the Numerical Guidelines chart to make clear that
different Numerical Guidelines apply for Multi-Stock Events involving
five or more, but less than twenty, securities whose executions
occurred within a period of five minutes or less. In

addition, the Exchange proposes adding to the Numerical Guidelines
chart a row that contains the Numerical Guidelines (30%) for Multi-
Stock Events involving twenty or more securities whose executions
occurred within a period of five minutes or less.
    The Exchange proposes clarifying paragraph (c)(3) to make clear
that the additional factors set forth in that paragraph are not
intended to provide any discretion to an Exchange Official to deviate
from the guidelines that apply to Multi-Stock Events or to transactions
in securities subject to individual stock trading pauses. The Exchange
also proposes to add Extended Trading Hours executions as an additional
factor that may be considered to determine whether an execution is
clearly erroneous under paragraph (c)(3).\6\
---------------------------------------------------------------------------

    \6\ This change would conform the list of additional factors
identified in paragraph (c)(3) of the Exchange's Rule 52.4 to the
list of additional factors identified in other markets' clearly
erroneous rules. See, e.g., BATS Rule 11.17(c)(3).
---------------------------------------------------------------------------

    Finally, the Exchange proposes amending paragraph (e)(2), related
to appeals of clearly erroneous execution decisions by the Exchange, to
preserve non-appealability of all joint rulings between the Exchange
and one or more other market centers. The Exchange believes that
certainty and consistency is critical to reviews of related executions
that span multiple market centers. Accordingly, although the Exchange
has proposed deletion of such language from existing paragraph (c)(3),
the Exchange proposes adding such language back in to paragraph (e)(2)
to make clear that joint market rulings are not appealable.
2. Statutory Basis
    Approval of the rule change proposed in this submission is
consistent with the requirements of the Act and the rules and
regulations thereunder that are applicable to a national securities
exchange, and, in particular, with the requirements of Section 6(b) of
the Act.\7\ In particular, the proposed change is consistent with
Section 6(b)(5) of the Act,\8\ because it would promote just and
equitable principles of trade, remove impediments to, and perfect the
mechanism of, a free and open market and a national market system, and,
in general, protect investors and the public interest. The proposed
rule change is also designed to support the principles of Section
11A(a)(1) \9\ of the Act in that it seeks to assure fair competition
among brokers and dealers and among exchange markets. The Exchange
believes that the proposed rule meets these requirements in that it
promotes transparency and uniformity across markets concerning reviews
of potentially clearly erroneous executions in various contexts,
including reviews in the context of a Multi-Stock Event involving
twenty or more securities and reviews resulting from a Trigger Trade
and any executions occurring immediately after a Trigger Trade but
before a trading pause is in effect on the Exchange. Further, the
Exchange believes that the proposed changes enhance the objectivity of
decisions made by the Exchange with respect to clearly erroneous
executions.

Amendment 39-15548; AD 2008-12-05]

Airworthiness Directives; Boeing Model 777 Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Boeing Model 777 airplanes. This AD requires an inspection to determine
the manufacturer and manufacture date of the oxygen masks in the center
and outboard passenger service units, crew rests, and lavatory and
flight attendant oxygen boxes, as applicable. This AD also requires
related investigative/corrective actions if necessary. This AD results
from a report that several passenger masks with broken in-line flow
indicators were found following a mask deployment. We are issuing this
AD to prevent the in-line flow indicators of the passenger oxygen masks
from fracturing and separating, which could inhibit oxygen flow to the
masks and consequently result in exposure of the passengers and cabin
attendants to hypoxia following a depressurization event.

DATES: This AD is effective July 16, 2008.
    The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of July 16,
2008.

ADDRESSES: For service information identified in this AD, contact
Boeing Commercial Airplanes, P.O. Box 3707, Seattle, Washington 98124-
2207.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an airworthiness directive (AD) that would apply to
certain Boeing Model 777 airplanes. That NPRM was published in the
Federal Register on January 10, 2008 (73 FR 1844). That NPRM proposed
to require an inspection to determine the manufacturer and manufacture
date of the oxygen masks in the center and outboard passenger service
units (PSUs), crew rests, and lavatory and flight attendant oxygen
boxes, as applicable. The NPRM also proposed to require related
investigative/corrective actions if necessary.

Comments

    We gave the public the opportunity to participate in developing
this AD. We considered the comments received from the two commenters.

Request To Revise the Relevant Service Information Section

    Boeing requests that we revise the Relevant Service Information
section of the NPRM to include a general visual inspection of the flow
indicator to determine whether the letter ``W'' appears on the right
side of the identification (ID) label. Boeing states that this
inspection should be included in the NPRM, since the presence of the
letter ``W'' on the ID label indicates that the corrective actions have
already been accomplished.
    We agree to clarify the related investigative and corrective
actions required by this AD. If the ID label on the oxygen mask shows
that the mask was manufactured by B/E Aerospace between January 1, 2002
and March 1, 2006, then the related investigative action must be done.
The related investigative action includes doing a general visual
inspection of the flow indicator to determine the color of the flow
direction mark and the word ``flow'' on the flow indicator, and to
determine whether the letter ``W'' appears on the right side of the ID
label. If the flow direction mark and the word ``flow'' on the flow
indicator of the oxygen mask are not green and the letter ``W'' is not
shown on the right side of the ID label, then the corrective action
must be done. The corrective action includes replacing the oxygen mask
with one that was not manufactured by B/E Aerospace between January 1,
2002, and March 1, 2006, or with a modified oxygen mask having an
improved flow indicator. We have revised paragraph (f) of this AD
accordingly. (Boeing Special Attention Service Bulletin 777-35-0019,
dated March 9, 2006, refers to B/E Aerospace Service Bulletin 174080-
35-01, dated February 6, 2006; and Revision 1, dated May 1, 2006; as
additional sources of service information for modifying the oxygen mask
assembly by replacing the flow indicator with an improved flow
indicator.) The intent of this AD is to accomplish all of the
applicable actions specified in the Accomplishment Instructions of
Boeing Special Attention Service Bulletin 777-35-0019. Since the
Relevant Service Information section is not retained in an AD, we have
not changed this AD in this regard.

Request To Revise the Discussion Section

    Boeing requests that we add a statement to the Discussion section
of the NPRM clarifying that only masks manufactured by B/E Aerospace
between January 1, 2002 and March 1, 2006 would require corrective
action. Boeing states that no further action is required for oxygen
masks manufactured outside those dates or manufactured by other
suppliers. Boeing also states that not including all of the contents of
Boeing Special Attention Service Bulletin 777-35-0019 in this AD, and
not clarifying the intent of the AD, will generate many requests for
clarification from operators.
    We have clarified the requirements of this AD in our response to
the previous comment. No additional change to this AD is necessary in
this regard, since the Discussion section of the NPRM is not retained
in this final rule.

Request To Delete Certain Requirements or Add a Terminating Action

    British Airways states that it does not agree with the proposed
requirement to replace a discrepant oxygen mask with one having an
improved flow indicator because only the oxygen masks identified in
Boeing Special Attention Service Bulletin 777-35-0019 are potentially
defective. The commenter also states that it has inspected some of its
airplanes and replaced all discrepant masks with new masks that do not
fall within the rejection criteria. The commenter believes that it
should not have to re-inspect the oxygen mask assemblies for the
presence of an improved flow indicator after this AD is issued. The
commenter, therefore, requests that we revise this AD in either one of
the following ways:
     Delete the phrase from paragraph (f) of this AD that
states ``* * * except where the service bulletin specifies installing a
new oxygen mask, replace the oxygen mask with a new or modified oxygen
mask having an improved flow indicator.''
     Add a statement to this AD specifying that inspections
done in accordance with Boeing Special Attention Service Bulletin 777-
35-0019 before issuance of this AD comply with the intent of this AD
and do not need to be repeated.
    We agree that inspections done in accordance with Boeing Special
Attention Service Bulletin 777-35-0019 before the effective date of
this AD do not need to be accomplished again. However, no change is
necessary in this regard, since a similar statement is contained
already in paragraph (e) of this AD. Further, as stated previously, we
have clarified the phrase regarding replacement of the oxygen mask in
paragraph (f) of this AD. The intent of that phrase is to provide the
option of replacing a discrepant oxygen mask with one that was not
manufactured by B/E Aerospace between January 1, 2002, and March 1,
2006, or with a modified oxygen mask having an improved flow indicator
in accordance with B/E Aerospace Service Bulletin 174080-35-01.

Conclusion

    We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
the AD with the change described previously. We also determined that
this change will not increase the economic burden on any operator or
increase the scope of the AD.

Costs of Compliance

    There are about 433 airplanes of the affected design in the
worldwide fleet. This AD affects about 123 airplanes of U.S. registry.
The required actions take about 70 work hours per airplane, with an
average of 480 oxygen masks per airplane, at an average labor rate of
$80 per work hour. Based on these figures, the estimated cost of the AD
for U.S. operators is $688,800, or $5,600 per airplane.

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.
    We are 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) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979), 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.
    You can find our regulatory evaluation and the estimated costs of
compliance in the AD Docket.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2008-12-05 Boeing: Amendment 39-15548. Docket No. FAA-2007-0393;
Directorate Identifier 2007-NM-183-AD.

Effective Date

    (a) This airworthiness directive (AD) is effective July 16,
2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Boeing Model 777-200, -200LR, -300, and -
300ER series airplanes, certificated in any category; as identified
in Boeing Special Attention Service Bulletin 777-35-0019, dated
March 9, 2006.

Unsafe Condition

    (d) This AD results from a report that several passenger masks
with broken in-line flow indicators were found following a mask
deployment. We are issuing this AD to prevent the in-line flow
indicators of the passenger oxygen masks from fracturing and
separating, which could inhibit oxygen flow to the masks and
consequently result in exposure of the passengers and cabin
attendants to hypoxia following a depressurization event.

Compliance

    (e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.

Inspection and Related Investigative/Corrective Actions if Necessary

    (f) Within 60 months after the effective date of this AD, do a
general visual inspection to determine the manufacturer and
manufacture date of the oxygen masks in the center and outboard
passenger service units, crew rests, and lavatory and flight
attendant oxygen boxes, as applicable, and do the applicable related
investigative and corrective actions, by accomplishing all of the
applicable actions specified in the Accomplishment Instructions of
Boeing Special Attention Service Bulletin 777-35-0019, dated March
9, 2006; except where the service bulletin specifies installing a
new oxygen mask, replace the oxygen mask with one that was not
manufactured by B/E Aerospace between January 1, 2002, and March 1,
2006, or with a modified oxygen

mask having an improved flow indicator. The related investigative
and corrective actions must be done before further flight.

    Note 1: The Boeing service bulletin refers to B/E Aerospace
Service Bulletin 174080-35-01, dated February 6, 2006; and Revision
1, dated May 1, 2006; as additional sources of service information
for modifying the oxygen mask assembly by replacing the flow
indicator with an improved flow indicator.

Alternative Methods of Compliance (AMOCs)

    (g)(1) The Manager, Seattle Aircraft Certification Office, FAA,
has the authority to approve AMOCs for this AD, if requested in
accordance with the procedures found in 14 CFR 39.19.
    (2) To request a different method of compliance or a different
compliance time for this AD, follow the procedures in 14 CFR 39.19.
Before using any approved AMOC on any airplane to which the AMOC
applies, notify your appropriate principal inspector (PI) in the FAA
Flight Standards District Office (FSDO), or lacking a PI, your local
FSDO.

Material Incorporated by Reference

    (h) You must use Boeing Special Attention Service Bulletin 777-
35-0019, dated March 9, 2006, to do the actions required by this AD,
unless the AD specifies otherwise.

Contact Name: Russell G. Oliver Phone No.: ( 225) 562 3501 Name: Bob Southworth Eastern Research Group, Inc.

GENERAL SUBJECT: SIC Code for Uncle Sam and Faustina facilities TOPICS DISCUSSED AND ACTION TAKEN On November 18, 2003, I spoke with Russell G. Oliver of IMC Phosphates Co. concerning the SIC code for two IMC Phosphates facilities. One facility is located in Uncle Sam, LA., and the other facility is located in Donaldson, LA. ( i. e., the Faustina facility).

Mr. Oliver said that the Uncle Sam facility produces sulfuric acid by burning sulfur and that all of the sulfuric acid produced is used in the manufacture of phosphoric acid. The only wastewater generated by this process is non contact cooling water. There is also runoff from storage piles. The NPDES permit for this facility contains a pH requirement for the non contact cooling water just in case the cooling water accidentally contacts the process water.

Other operations at the Uncle Sam facility include the manufacture of phosphoric acid by a wet process, the defluorination of phosphoric acid, and the manufacture of hydrofluoric acid. Mr. Oliver agreed that the SIC Code for the Uncle Sam facility is 2874 ( phosphates), not 2873 ( fertilizer).

Mr. Oliver said that the operations at the Faustina facility include the production of ammonia and three finished fertilizer processes in which phosphoric acid produced at the Uncle Sam facility is mixed with ammonia produced at the Faustina facility. However, effluent limits for the Faustina facility, which require double lime treatment of runoff, are from the effluent limitations guidelines for the phosphate category. Mr. Oliver didn't know which SIC code should be assigned to the Faustina facility.

ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R08-OAR-2021-0002; FRL-10024-54-Region 8]

Approval and Promulgation of Implementation Plans; North Dakota;
Revisions to Air Pollution Control Rules; Regional Haze

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is finalizing
approval on a revision to the North Dakota State Implementation Plan
(SIP) submitted by the State of North Dakota on November 11, 2016 and
supplemented on March 15, 2021, that addresses amendments to the
regional haze provisions of the North Dakota Administrative Code
(NDAC). These revisions were submitted to remove certain regional haze
requirements related to Best Available Retrofit Technology (BART) in
the first planning period. EPA is also finalizing approval on a
revision to the North Dakota SIP submitted on August 3, 2020, that
addresses additional amendments to the regional haze provisions of the
NDAC. The 2020 SIP revision was submitted to update the incorporation
by reference date for regional haze definitions, add emission reduction
requirements to make reasonable progress during the second and
subsequent regional haze planning periods, and revise the regional haze
monitoring, recordkeeping, and reporting requirements to be applicable
under the second and subsequent planning period. EPA is taking this
action pursuant to section 110 and Part C of the Clean Air Act (CAA).

DATES: This rule is effective on July 8, 2021.

ADDRESSES: The EPA has established a docket for this action under
Docket ID No. EPA-R08-OAR-2021-0002. All documents in the docket are
listed on the http://www.regulations.gov website. Although listed in
the index, some information is not publicly available, e.g., CBI or
other information whose disclosure is restricted by statute. Certain
other material, such as copyrighted material, is not placed on the
internet and will be publicly available only in hard copy form.

Division, EPA, Region 8, Mailcode 8ARD-IO, 1595 Wynkoop Street, Denver,
Colorado 80202-1129,<PHONE_NUMBER><EMAIL_ADDRESS>
SUPPLEMENTARY INFORMATION: Throughout this document ``we,'' ``us,'' and
``our'' means the EPA.

I. Background

    The background for this action is discussed in detail in our April
1, 2021 proposal (86 FR 17101). In that document we proposed to approve
North Dakota's regional haze SIP revision submitted by the State of
North Dakota on November 11, 2016 and supplemented on March 15, 2021.
Specifically, we proposed to approve North Dakota's removal of NDAC
section 33-15-25-02.1 (requirement pertaining to the submittal of a
regional haze BART analysis) and section 33-15-25-03 (requirement that
references the federal guidelines for BART determinations under the
regional haze rule) from the regional haze provisions provided in NDAC
section 33-15-25.\1\
---------------------------------------------------------------------------

    \1\ On August 6, 2018, North Dakota submitted a SIP to EPA that
recodified the Air Pollution Control Rules, including those that
address regional haze, from NDAC section 33-15 to NDAC section 33.1-
15. EPA approved the recodification on February 5, 2019 (84 FR
1610). The recodification made the regional haze section of NDAC to
be changed from section 33-15-25 to section 33.1-15-25. The 2018 SIP
reflected the deletions of section 33.1-15-25-02.1 and section 33.1-
15.25-03 (formerly referred to as section 33-15-25-02.1 and section
33-15-25-03).
---------------------------------------------------------------------------

    We also proposed to approve a portion of North Dakota's August 3,
2020, SIP revision that addresses NDAC section 33.1-15-25 of the Air
Pollution Control Rules for regional haze.\2\ Specifically, we proposed
to approve the following revisions to NDAC: Section 33.1-15-25-01 which
updates the incorporation by reference date for regional haze
definitions; section 33.1-15-25-03 which adds emission reduction
requirements to make reasonable progress for the second and subsequent
planning periods; and section 33.1-15-25-04 which revises the regional
haze monitoring, recordkeeping, and reporting requirements to be
applicable to sources under the second and subsequent planning periods.
---------------------------------------------------------------------------

    \2\ EPA will act on the remaining portions of the ND August 3,
2020, SIP in a separate future rulemaking.
---------------------------------------------------------------------------

    We did not receive any comments on the proposed rule.

II. Final Action

    In this action, EPA is finalizing approval on SIP amendments to
North Dakota Air Pollution Control Rules, shown in Table 1, submitted
by the State of North Dakota on November 11, 2016, and supplemented
March 15, 2021, and August 3, 2020.

                                15, 2021
NDAC section 33-15-25-02.1,\3\ NDAC section 33-15-25-03.\4\

            Amended Sections in the August 3, 2020 Submittal
NDAC section 33.1-15-25-01, NDAC section 33.1-15-25-03, NDAC section
 33.1-15-25-04.

III. Incorporation by Reference
---------------------------------------------------------------------------

    \3\ Since North Dakota's NDAC recodification in 2018, section
33-15-25-02.1 is referred to as section 33.1-15-25-02.1.
    \4\ Since North Dakota's NDAC recodification in 2018, section
33-15-25-03 is referred to as section 33.1-15-25-03.
---------------------------------------------------------------------------

    In this document, EPA is finalizing regulatory text that includes
incorporation by reference. In accordance with requirements of 1 CFR
51.5, EPA is finalizing the incorporation

by reference of NDAC as described in section II of this preamble. EPA
has made, and will continue to make, these materials generally
available through www.regulations.gov and at the EPA Region 8 Office
(please contact the person identified in the FOR FURTHER INFORMATION
CONTACT section of this preamble for more information). Therefore,
these materials have been approved by EPA for inclusion in the SIP,
have been incorporated by reference by EPA into that plan, are fully
federally enforceable under sections 110 and 113 of the CAA as of the
effective date of the final rulemaking of EPA's approval, and will be
incorporated by reference in the next update to the SIP compilation.\5\
---------------------------------------------------------------------------

    \5\ 62 FR 27968 (May 22, 1997).
---------------------------------------------------------------------------

IV. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a
SIP submission that complies with the provisions of the Act and
applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a).
Thus, in reviewing SIP submissions, the EPA's role is to approve state
choices, provided that they meet the criteria of the Clean Air Act.
Accordingly, this action merely approves state law as meeting Federal
requirements and does not impose additional requirements beyond those
imposed by state law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to
review by the Office of Management and Budget under Executive Orders
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21,
2011);
     Does not impose an information collection burden under the
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Is certified as not having a significant economic impact
on a substantial number of small entities under the Regulatory
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or
uniquely affect small governments, described in the Unfunded Mandates
Reform Act of 1995 (Pub. L. 104-4);
     Does not have Federalism implications as specified in
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based
on health or safety risks subject to Executive Order 13045 (62 FR
19885, April 23, 1997);
     Is not a significant regulatory action subject to
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of section 12(d) of the
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272
note) because application of those requirements would be inconsistent
with the CAA; and
     Does not provide EPA with the discretionary authority to
address, as appropriate, disproportionate human health or environmental
effects, using practicable and legally permissible methods, under
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, the SIP is not approved to apply on any Indian
reservation land or in any other area where EPA or an Indian tribe has
demonstrated that a tribe has jurisdiction. In those areas of Indian
country, the rule does not have tribal implications and will not impose
substantial direct costs on tribal governments or preempt tribal law as
specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the
Small Business Regulatory Enforcement Fairness Act of 1996, generally
provides that before a rule may take effect, the agency promulgating
the rule must submit a rule report, which includes a copy of the rule,
to each House of the Congress and to the Comptroller General of the
United States. EPA will submit a report containing this action and
other required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the rule in the Federal Register. A major rule cannot
take effect until 60 days after it is published in the Federal
Register. This action is not a ``major rule'' as defined by 5 U.S.C.
804(2).
    Under section 307(b)(1) of the Clean Air Act, petitions for
judicial review of this action must be filed in the United States Court
of Appeals for the appropriate circuit by August 9, 2021. Filing a
petition for reconsideration by the Administrator of this final rule
does not affect the finality of this action for the purposes of
judicial review nor does it extend the time within which a petition for
judicial review may be filed, and shall not postpone the effectiveness
of such rule or action. This action may not be challenged later in
proceedings to enforce its requirements (see section 307(b)(2)).
