or use of pesticides.

B. What should I consider as I prepare my comments for EPA?

    1. Submitting CBI. Do not submit this information to EPA through
regulations.gov or email. Clearly mark the part or all of the
information that you claim to be CBI. For CBI information in a disk or
CD-ROM that you mail to EPA, mark the outside of the disk or CD-ROM as
CBI and then identify electronically within the disk or CD-ROM the
specific information that is claimed as CBI. In addition to one
complete version of the comment that includes information claimed as
CBI, a copy of the comment that does not contain the information
claimed as CBI must be submitted for inclusion in the public docket.
Information so marked will not be disclosed except in accordance with
procedures set forth in 40 CFR part 2.
    2. Tips for preparing your comments. When preparing and submitting
your comments, see the commenting tips at https://www.epa.gov/dockets/comments.html.

II. What action is the Agency taking?

    This notice announces receipt by the Agency of requests from
registrants to cancel certain pesticide products registered under FIFRA
section 3 (7 U.S.C. 136a) or 24(c) (7 U.S.C. 136v(c)). These
registrations are listed in sequence by registration number (or company
number and 24(c) number) in Table 1 of this unit.
    Unless the Agency determines that there are substantive comments
that warrant further review of the requests or the registrants withdraw
their requests, EPA intends to issue an order in the Federal Register
canceling all of the affected registrations.

III. What is the Agency's authority for taking this action?

    Section 6(f)(1) of FIFRA (7 U.S.C. 136d(f)(1)) provides that a
registrant of a pesticide product may at any time request that any of
its pesticide registrations be canceled. FIFRA further provides that,
before acting on the request, EPA must publish a notice of receipt of
any such request in the Federal Register.
    Section 6(f)(1)(B) of FIFRA (7 U.S.C. 136d(f)(1)(B)) requires that
before acting on a request for voluntary cancellation, EPA must provide
a 30-day public comment period on the request for voluntary
cancellation or use termination. In addition, FIFRA section 6(f)(1)(C)
(7 U.S.C. 136d(f)(1)(C)) requires that EPA provide a 180-day comment
period on a request for voluntary cancellation or termination of any
minor agricultural use before granting the request, unless:
    1. The registrants request a waiver of the comment period, or
    2. The EPA Administrator determines that continued use of the
pesticide would pose an unreasonable adverse effect on the environment.
    The registrants in Table 2 of Unit II, have requested that EPA
waive the 180-day comment period. Accordingly, EPA will provide a 30-
day comment period on the proposed requests.

IV. Procedures for Withdrawal of Request

    Registrants who choose to withdraw a request for cancellation
should submit such withdrawal in writing to the person listed under FOR
FURTHER INFORMATION CONTACT. If the products have been subject to a
previous cancellation action, the effective date of cancellation and
all other provisions of any earlier cancellation action are
controlling.

V. Provisions for Disposition of Existing Stocks

    Existing stocks are those stocks of registered pesticide products
that are currently in the United States and that were packaged,
labeled, and released for shipment prior to the effective date of the
cancellation action. Because the Agency has identified no significant
potential risk concerns associated with these pesticide products, upon
cancellation of the products identified in Table 1 of Unit II, EPA
anticipates allowing registrants to sell and distribute existing stocks
of these products for 1 year after publication of

the Cancellation Order in the Federal Register.
    Thereafter, registrants will be prohibited from selling or
distributing the pesticides identified in Table 1 of Unit II, except
for export consistent with FIFRA section 17 (7 U.S.C. 136o) or for
proper disposal. Persons other than registrants will generally be
allowed to sell, distribute, or use existing stocks until such stocks
are exhausted, provided that such sale, distribution, or use is
consistent with the terms of the previously approved labeling on, or
that accompanied, the canceled products.
    Authority: 7 U.S.C. 136 et seq.

Airworthiness Directives; Boeing Model 737-300 and -400 Series
Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD)
for certain Boeing Model 737-300 and -400 series airplanes. This
proposed AD would require testing and inspecting a certain web panel of
the main wheel well pressure deck to determine the material type and
thickness; and related investigative and corrective actions if
necessary. This proposed AD results from several reports indicating
that cracks ranging from 0.8 to 8.0 inches long were found on a certain
web panel of the main wheel well pressure deck. We are proposing this
AD to prevent fatigue cracking in the web panel of the main wheel well
pressure deck, which could result in venting and consequent rapid
decompression of the airplane.

DATES: We must receive comments on this proposed AD by February 25,
2008.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Portal: Go to http://www.regulations.gov.
 Follow the instructions for submitting comments.

     Fax:<PHONE_NUMBER>.

Discussion

    We have received several reports indicating that cracks ranging
from 0.8 to 8.0 inches long were found on a certain web panel of the
main wheel well pressure deck. These cracks were found on certain
Boeing Model 737-300 and -400 series airplanes. Boeing analyzed pieces
of the cracked web sections on three airplanes and found that in each
case, the webs were made of the wrong material type and thickness.
According to design, the web should be 0.050 inch thick 2024-T42 bare
sheet. The webs were found to be 7075 Clad material, with thicknesses
of 0.040 inches nominal. (Webs made from this material and thickness
are more likely to crack.) The flight cycles on the airplanes when the
cracking was found ranged from 13,332 to 22,849 total flight cycles.
Cracking in the web panel, if not corrected, could result in venting
and consequent rapid decompression of the airplane.

Relevant Service Information

    We have reviewed Boeing Special Attention Service Bulletin 737-57-
1289, dated June 13, 2007. The service bulletin describes procedures
for testing and inspecting a certain web panel of the main wheel well
pressure deck to determine if the material type and thickness are
discrepant, and performing related investigative and corrective actions
if necessary.
    The testing and inspection procedures include performing either a
one-time chemical spot test or a one-time evaluation with a Scanning
Electron Microscope (SEM) of the web material of the main wheel well
pressure deck to determine the type of web material, and performing a
one-time ultrasonic inspection to determine the material thickness. For
airplanes on which the web thickness is discrepant (the thickness is
less than 0.047 inches, or if the web material is 7000 series
aluminum), the procedures for the related investigative and corrective
actions include the following:
     For airplanes on which the web thickness is less than
0.037 inches, replace the web panel before further flight.
     For airplanes on which the web thickness is greater than
or equal to 0.037 inches and less than 0.047 inches, or the web
material is 7000 series aluminum: Perform a detailed inspection for any
crack and a general visual inspection for any corrosion before further
flight. If no crack or corrosion is found, repeat the inspections until
the web panel is replaced. Accomplishing the replacement eliminates the
need for the repetitive inspections.
    If any crack or corrosion is found during any inspection, replace
the web panel or contact Boeing for repair instructions and repair
before further flight.
    Accomplishing the actions specified in the service information is
intended to adequately address the unsafe condition.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an
unsafe condition that is likely to exist or develop on other airplanes
of this same type design. For this reason, we are proposing this AD,
which would require accomplishing the actions specified in the service
information described previously, except as discussed under
``Difference Between the Proposed AD and Service Information.''

Difference Between the Proposed AD and Service Information

    The service bulletin specifies to contact the manufacturer for
instructions on how to repair certain conditions, but this proposed AD
would require repairing those conditions in one of the following ways:
     Using a method that we approve; or
     Using data that meet the certification basis of the
airplane, and that have been approved by an Authorized Representative
for the Boeing Commercial Airplanes Delegation Option Authorization
Organization whom we have authorized to make those findings.

Costs of Compliance

    There are about 31 airplanes of the affected design in the
worldwide fleet. This proposed AD would affect about 1 airplane of U.S.
registry. The proposed tests and inspections would take about 3 work
hours per airplane, at an average labor rate of $80 per work hour.
Based on these figures, the estimated cost of the proposed AD for this
U.S. operator is $240.

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

    We have determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 the proposed
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order
12866;
    2. Is not a ``significant rule'' under the 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.
    We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket. See the
ADDRESSES section for a location to examine the regulatory evaluation.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Safety.

The Proposed Amendment

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

PART 39--AIRWORTHINESS DIRECTIVES

    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]

    2. The Federal Aviation Administration (FAA) amends Sec.  39.13 by
adding the following new airworthiness directive (AD):

Boeing: Docket No. FAA-2007-0395; Directorate Identifier 2007-NM-
157-AD.

Comments Due Date

    (a) The FAA must receive comments on this AD action by February
25, 2008.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Boeing Model 737-300 and -400 series
airplanes, certificated in any category; as identified in Boeing
Special Attention Service Bulletin 737-57-1289, dated June 13, 2007.

Unsafe Condition

    (d) This AD results from several reports indicating that cracks
ranging from 0.8 to 8.0 inches long were found on a certain web
panel of the main wheel well pressure deck. We are issuing this AD
to prevent fatigue cracking in the web panel of the main wheel well
pressure deck, which could result in venting and consequent rapid
decompression of the airplane.

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.

Testing/Inspecting/Investigative and Corrective Actions

    (f) Within 6 months after the effective date of this AD: Do a
test of the web panel of the main wheel well pressure deck to
determine the material type, and do an ultrasonic inspection to
determine material thickness, by doing all the applicable actions
specified in the Accomplishment Instructions of Boeing Special
Attention Service Bulletin 737-57-1289, dated June 13, 2007.
    (g) For airplanes on which the web thickness or material is
found to be discrepant during the test and inspection required by
paragraph (f) of this AD, accomplish the applicable actions
specified in paragraphs (g)(1) and (g)(2) of this AD at the time
specified, in accordance with the Accomplishment Instructions of
Boeing Special Attention Service Bulletin 737-57-1289, dated June
13, 2007.
    (1) Do all applicable related investigative and corrective
actions (including detailed and general visual inspections) before
further flight, by doing all the actions specified in the
Accomplishment Instructions of the service bulletin; except as
provided by paragraph (h) of this AD. Repeat the inspections
thereafter at intervals not to exceed 1,000 flight cycles until
paragraph (g)(2) of this AD has been done.
    (2) Within 30 months or 6,000 flight cycles after accomplishing
the actions required by paragraph (g)(1) of this AD, whichever is
later, replace the web panel in accordance with the Accomplishment
Instructions of the service bulletin. Doing this replacement ends
the repetitive inspections required by paragraph (g)(1) of this AD.

Corrective Actions

    (h) If any crack or corrosion is found during any inspection
required by paragraph (g)(1) of this AD, and Boeing Special
Attention Service Bulletin 737-57-1289, dated June 13, 2007,
specifies to contact Boeing for repair instructions: Before further
flight, repair according to a method approved in accordance with the
procedures specified in paragraph (i) of this AD.

Alternative Methods of Compliance (AMOCs)

    (i)(1) The Manager, Seattle ACO, 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.
    (3) An AMOC that provides an acceptable level of safety may be
used for any repair required by this AD, if it is approved by an
Authorized Representative for the Boeing Commercial Airplanes
Delegation Option Authorization Organization who has been authorized
by the Manager, Seattle ACO, to make those findings. For a repair
method to be approved, the repair must meet the certification basis
of the airplane, and the approval must specifically refer to this
AD.

    Issued in Renton, Washington, on December 21, 2007.

SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-78684; File No. SR-CHX-2016-15]

Self-Regulatory Organizations; Chicago Stock Exchange, Inc.;
Notice of Filing and Immediate Effectiveness of a Proposed Rule Change
To Modify the Handling of Intermarket Sweep Orders

August 25, 2016.
    Pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934
(''Act''),\1\ and Rule 19b-4 \2\ thereunder, notice is hereby given
that on August 17, 2016, the Chicago Stock Exchange, Inc. (''CHX'' or
the ``Exchange'') filed with the Securities and Exchange Commission
(''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.
---------------------------------------------------------------------------

    \1\ 15 U.S.C. 78s(b)(1).
    \2\ 17 CFR 240.19b-4.
---------------------------------------------------------------------------

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

    CHX proposes to amend the Rules of the Exchange (''CHX Rules'') to
modify the handling of Intermarket Sweep Orders (''ISOs'').
    CHX has designated this proposed rule change as non-controversial
pursuant to Section 19(b)(3)(A) \3\ of the Act and Rule 19b-4(f)(6) \4\
thereunder and has provided the Commission with the notice required by
Rule 19b-4(f)(6)(iii).\5\

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

    The text of this proposed rule change is available on the
Exchange's Web site at (www.chx.com) and in the Commission's Public
Reference Room.

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 CHX included statements
concerning the purpose of and basis for the proposed rule changes and
discussed any comments it received on the proposed rule change. The
text of these statements may be examined at the places specified in
Item IV below. The CHX has prepared summaries, set forth in sections A,
B and C below, of the most significant aspects of such statements.

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

1. Purpose
    The Exchange proposes various amendments to the CHX Rules to amend
the operation of the Exchange's ISO modifiers as follows:

     Amend the operation of the ISO modifier to be similar
to the ISO modifiers offered by other national securities
exchanges.\6\ As amended, a limit order marked ISO (''ISO limit'')
would behave like a simple limit order \7\ (i.e., executable through
multiple price points not beyond its limit price with the unexecuted
balance to be immediately cancelled or ranked on the CHX book
depending on the attached Time-In-Force \8\ and display modifier
\9\), but without regard to the Protected Quotations \10\ of away
markets when it is being processed as a new incoming order.
---------------------------------------------------------------------------

    \6\ See e.g., NYSE ARCA Equities Rule 7.31(e)(2); see also e.g.,
Bats BYX Rule 11.9(d).
    \7\ See CHX Article 1, Rule 2(a)(1).
    \8\ See CHX Article 1, Rule 2(d).
    \9\ See CHX Article 1, Rule 2(e).
    \10\ See 17 CFR 242.600(b)(58).
---------------------------------------------------------------------------

     Require a limit order marked by any one of the
Exchange's three ISO modifiers (i.e., BBO ISO,\11\ Price-Penetrating
ISO,\12\ and ISO \13\) to be handled as if it were marked ISO, as
amended.\14\
---------------------------------------------------------------------------

    \11\ See CHX Article 1, Rule 2(b)(1)(A).
    \12\ See CHX Article 1, Rule 2(b)(1)(E).
    \13\ See CHX Article 1, Rule 2(b)(3)(B).
    \14\ In order to facilitate the transition to the amended ISO,
the Exchange does not propose to eliminate the BBO ISO and Price-
Penetrating ISO modifiers at this time.

The Exchange also proposes to clarify the current handling of cross
orders \15\ marked ISO (``ISO cross'') and Participants' \16\
obligations with respect to ISOs.
---------------------------------------------------------------------------

    \15\ See CHX Article 1, Rule 2(a)(2).
    \16\ A ``Participant'' is a ``member'' of the Exchange for
purposes of the Act. See CHX Article 1, Rule 1(s).

    The Exchange believes that the proposed rule change will harmonize
the operation of the Exchange's ISO modifier with ISO modifiers offered
by other national securities exchanges, as well as clarify and simplify
the order types and modifiers offered by the Exchange, all of which
further the objectives of the Act, as described below.
Current CHX ISOs
    The Exchange currently offers three different ISO modifiers: BBO
ISO, Price-Penetrating ISO, and ISO.\17\ While all three modifiers can
be used to mark an order as required by Rule 600(b)(30) of Regulation
NMS,\18\ each modifier is handled differently by the CHX Matching
System (''Matching System'').\19\
---------------------------------------------------------------------------

    \17\ BBO ISO and Price-Penetrating ISOs are limit order
modifiers, whereas ISO is a limit and cross order modifier. The
Exchange last modified the operation of BBO ISO and Price-
Penetrating ISO in 2014. See Securities Exchange Act Release No.
73572 (November 10, 2014), 79 FR 68736 (November 18, 2014) (SR-CHX-
2014-18).
    \18\ See 17 CFR 242.600(b)(30).
    \19\ The Matching System is an automated order execution system,
which is a part of the Exchange's ``Trading Facilities,'' as defined
under CHX Article 1, Rule 1(z).
---------------------------------------------------------------------------

    An incoming BBO ISO will execute against orders resting on the CHX
book at prices not to exceed the more restrictive of its limit price or
the contra-side displayed best bid or offer. Any unexecuted balance of
the BBO ISO will be immediately cancelled if -1- marked Immediate Or
Cancel (''IOC'') \20\ or -2- the incoming BBO ISO sell (buy) order
could execute against any resting order(s) priced below (above) the
displayed best bid (offer), regardless of the Time-In-Force. If the
unexecuted balance of the BBO ISO would not be cancelled as described
above, it will be ranked on the CHX Book and will be displayable at its
limit price. A limit order marked BBO ISO may not be marked Do Not
Display.\21\ The Matching System, in executing the ISO as soon as the
order is received by the Matching System, will not take any of the
actions described in Article 20, Rule 5 to prevent an improper trade-
through or any of the actions described in Article 20, Rule 6 to
prevent a locked or crossed market; provided, however, that in
executing any initially unexecuted balance of the ISO that is placed in
the Matching System, the requirements of Article 20, Rule 5 will be
followed. These orders shall be executed on the assumption that the
Participant routing the order to the Matching System has already
satisfied the quotations of other markets as required by Rule
600(b)(30) \22\ and shall be displayed

because the Participant routing the order to the Matching System has
already satisfied the quotations of other markets as required by
Article 20, Rule 6(c)(3). A limit order marked BBO ISO shall be deemed
to have been received Do Not Route,\23\ which cannot be overridden by
the order sender.
---------------------------------------------------------------------------

    \20\ See CHX Article 1, Rule 2(d)(4).
    \21\ See CHX Article 1, Rule 2(c)(2).
    \22\ 17 CFR 242.600(b)(30).
    \23\ See CHX Article 1, Rule 2(b)(3)(A).
---------------------------------------------------------------------------

    A Price-Penetrating ISO will execute at or better than its limit
price as soon as the order is received by the Matching System, with any
unexecuted balance of the order to be immediately cancelled, as it is
always handled IOC. A Price-Penetrating ISO cannot be displayed or
otherwise post to the CHX book. Price-Penetrating ISOs will execute
against any eligible orders in the Matching System (including any
Reserve Size or undisplayed orders) through multiple price points. The
Matching System, in executing these orders, will not take any of the
actions described in Article 20, Rule 5 to prevent an improper trade-
through. A limit order marked Price-Penetrating ISO shall be deemed to
have been received IOC, which cannot be overridden by the order sender.
    ISO is a limit and cross order modifier. A limit order marked ISO
that is not marked BBO ISO is deemed to have been received Price-
Penetrating ISO, which cannot be overridden by the order sender. Thus,
a limit order marked ISO will always be handled as a BBO ISO or Price-
Penetrating ISO. A cross order marked ISO is handled like a simple
cross order, except that the Exchange would not take any actions
described in Article 20, Rule 5 to prevent an improper trade-
through.\24\
---------------------------------------------------------------------------

    \24\ In eliminating the definition of ``ISO Cross'' in 2013, the
Exchange explained that ``ISO Cross is simply a cross order marked
ISO and not a distinct order modifier.'' See Exchange Act Release
No. 69538 (May 8, 2013), 78 FR 28671 (May 15, 2013) (SR-CHX-2013-
10).
---------------------------------------------------------------------------

Amended CHX ISOs
    The Exchange now proposes to amend the definition of ``ISO'' under
Article 1, Rule 2(b)(3)(B) so that the amended ISOs behave like ISOs
offered by other national securities exchanges.\25\ Specifically, the
Exchange proposes to amend the definition of ISO to -1- require an ISO
limit to behave like a simple limit order (i.e., executable through
multiple price points not beyond its limit price with the unexecuted
balance to be immediately cancelled or posted to the CHX book depending
on the attached Time-In-Force), but without regard to the Protected
Quotations of away markets when it is being processed as a new incoming
order; \26\ -2- provide that the default Time-In-Force for an ISO limit
is IOC, unless it is marked with another available Time-In-Force \27\
(i.e., Day \28\ or GTD); \29\ -3- clarify the current applicability of
the ISO modifier to cross orders; -4- clarify that it is the
Participant's responsibility in complying with the requirements of
Regulation NMS when submitting an ISO to the Exchange; and -5- delete
obviated language. The mechanical result of these proposed amendments
is that an amended ISO limit will behave like the current Price-
Penetrating ISO, except that the amended ISO limit may have a Time-In-
Force other than IOC, which would permit the unexecuted balance of the
amended ISO limit to be ranked on the CHX book and displayable at its
limit price. To this end, amended Article 1, Rule 2(b)(3)(B) provides
as follows:
---------------------------------------------------------------------------

    \25\ See supra note 6.
    \26\ The Exchanges notes that the current BBO ISO may be ranked
on the CHX book if it is -1- not marked IOC and -2- does not execute
against any contra-side orders within the Matching System at prices
inferior to the then-current best displayed contra-side order on the
CHX book. See current CHX Article 1, Rule 2(b)(1)(A). As proposed,
an ISO will be permitted to be ranked on the CHX book even if a
portion of the ISO executes against contra-side orders within the
Matching System at prices inferior to the then-current best
displayed contra-side order on the CHX book.
    \27\ The Exchange notes that the Fill Or Kill modifier, as
defined under CHX Article 1, Rule 2(d)(2), has been unavailable
since December 4, 2013. Any order marked FOK will be rejected upon
receipt. See CHX Market Regulation Department Information Memorandum
No. MR-13-12 (December 3, 2013).
    \28\ See CHX Article 1, Rule 2(d)(1).
    \29\ See CHX Article 1, Rule 2(d)(3).

    ''Intermarket Sweep'' or ``ISO'': a limit or cross order
modifier that marks an order as required by SEC Rule 600(b)(30).\30\
The Exchange relies on the marking of an order as an ISO when
handling such an order, and thus, it is the entering Participant's
responsibility, not the Exchange's responsibility, to comply with
the requirements of Regulation NMS and Article 20, Rule 6(c)(3) \31\
relating to ISOs. Any new incoming order marked ISO will not be
rejected or cancelled if it would lock, cross, or trade-through a
Protected Quotation of an away market. ISOs shall be deemed to have
been received ``Do Not Route,'' as defined under paragraph
(b)(3)(A), which cannot be overridden by the order sender.
---------------------------------------------------------------------------

    \30\ See 17 CFR 242.600(b)(30).
    \31\ CHX Article 20, Rule 6(c)(3) excepts a Participants [sic]
from the locked and crossed markets prohibition described under CHX
Article 20, Rule 6(b) if ``The Exchange Participant displaying the
locking or crossing quotation simultaneously routed an intermarket
sweep order to execute against the full displayed size of any locked
or crossed protected quotation.''
---------------------------------------------------------------------------

    (i) ISO limit. A new incoming limit order marked ISO (''ISO
limit'') may be executed at one or multiple price levels in the
Matching System without regard to Protected Quotations at away
markets consistent with Regulation NMS. All ISO limits shall be
deemed to have been received IOC, unless an ISO limit is marked with
another Time-In-Force.
    (ii) ISO cross. A cross order marked ISO (''ISO cross'') may
execute at its crossing price as soon as it is received by the
Matching System without regard to Protected Quotations at away
markets consistent with Regulation NMS. An ISO cross that could not
be immediately executed within the Matching System upon receipt
shall be immediately cancelled.\32\
---------------------------------------------------------------------------

    \32\ Cross orders are always handled IOC. See CHX Article 1,
Rule 2(a)(2).

    The Exchange also proposes to amend Article 1, Rule 2(b)(1)(A) and
Article 1, Rule 2(b)(1)(E) to delete the current definition of BBO ISO
and Price-Penetrating ISO, respectively, and replace each definition
with language that provides that the modifier is a limit order modifier
that shall be handled as an ISO, as defined under amended paragraph
(b)(3)(B).\33\ Moreover, so as to contemplate the proposed default IOC
handling of ISO limits, the Exchange proposes to amend the definition
of ``Limit order'' under Article 1, Rule 2(a)(1) to provide that all
limit orders, except those marked Price-Penetrating ISO, BBO ISO, and
ISO, shall be deemed to have been received Day, if an order duration
modifier is not specified.
---------------------------------------------------------------------------

    \33\ See supra note 14.
---------------------------------------------------------------------------

Interaction With Certain Order Modifiers
    The Exchange notes that the amended ISO would be compatible with
all display modifiers (i.e., Always Quote,\34\ Do Not Display,\35\ and
Reserve Size \36\). A new incoming ISO limit marked Day and Do Not
Display would be permitted to trade-through and/or lock or cross
Protected Quotations of away markets and the unexecuted balance would
be ranked on the CHX book at its limit price. Similarly, a new incoming
ISO limit marked Day and Reserve Size would be permitted to trade-
through and/or lock or cross Protected Quotations of away markets and
the unexecuted balance would be ranked on the CHX book at its limit
price with the displayable portion displayed at its limit price. Also,
an ISO limit marked Day and Always Quote would be permitted to trade-
through and/or lock or cross Protected Quotations of away markets and
the unexecuted balance would be ranked on the CHX book if it could be
displayed at its limit price or cancelled if it could not be displayed
at its limit price.
---------------------------------------------------------------------------

    \34\ See CHX Article 1, Rule 2(c)(1).
    \35\ See CHX Article 1, Rule 2(c)(2).
    \36\ See CHX Article 1, Rule 2(c)(3).
---------------------------------------------------------------------------

    Moreover, if the Exchange were to receive an ISO limit marked CHX

Only,\37\ the Exchange will ignore the CHX Only modifier and handle the
ISO limit as if it were not marked CHX Only, which is consistent with
current practice.\38\ This is because the ISO and CHX Only modifiers
are incompatible in that ISO instructs the Exchange to ignore the
Protected Quotations of away markets when initially processing the
order, whereas CHX Only requires the Exchange to price slide the order
upon initial receipt to prevent locked and crossed markets.
---------------------------------------------------------------------------

    \37\ See CHX Article 1, Rule 2(b)(1)(C).
    \38\ See Securities Exchange Act Release No. 69075 (March 8,
2013), 78 FR 16311 (March 14, 2013) (SR-CHX-2013-07).
---------------------------------------------------------------------------

Examples
    The following Examples are illustrative of the amended ISO
modifier, but do not exhaustively depict every possible scenario
regarding ISOs. Moreover, the Examples do not necessarily depict the
actual technical processes of prioritizing messages and executing
orders.

    Example 1. Assume that proposed rule change is operative and the
following:
     The NBBO for security XYZ is 10.00 x 10.01.
     The displayed CHX BBO for XYZ is 9.99 x 10.01.
     There is only one buy order for XYZ priced at 9.99
resting on the CHX book (''CHX Buy Order'') and there are no
undisplayed orders for XYZ resting on the CHX book.
     There is only one away market with a Protected Bid for
XYZ at 10.00 (``Away Protected Bid'').
     All Protected Quotations in XYZ are for 100 shares.
    Assume then that the Exchange receives an ISO limit marked Day
to sell 200 shares of XYZ at 9.99 (''Incoming Sell ISO Limit'').
    Under this Example 1, the Exchange would execute 100 shares of
Incoming Sell ISO Limit against the CHX Buy Order at 9.99, without
taking any actions to prevent a trade-through of Away Protected Bid.
The Exchange would then rank and display the unexecuted 100 shares
of Incoming Sell ISO Limit at 9.99, without taking any actions to
prevent a crossed market.
    Example 2. Assume the same as Example 1, except that Incoming
Sell ISO Limit is not marked with a Time-In-Force. Under Example 2,
the unexecuted balance of Incoming Sell ISO Limit would be
cancelled, as the default handling for ISO limits is IOC.
    Example 3. Assume the same as Example 1, except that Incoming
Sell ISO Limit is marked Price-Penetrating ISO or BBO ISO and is
also marked Day. Under Example 3, Incoming Sell ISO Limit would be
handled as if it were marked ISO and would behave identically as
described under Example 1.
    Example 4. Assume the same as Example 1, except that Incoming
Sell ISO Limit is marked Price-Penetrating ISO or BBO ISO and is not
marked by a Time-In-Force. Under this Example 4, the Exchange would
cancel the unexecuted balance of Incoming Sell ISO Limit, as an ISO
that does not have a Time-In-Force identified would be handled IOC.
Operative Date
    The proposed rule change shall be operative pursuant to notice to
Participants on a date after the expiration of the 30-day preoperative
waiting period.
2. Statutory Basis
    The Exchange believes that the proposed rule change is consistent
with Section 6(b) of the Act in general,\39\ and furthers the
objectives of Section 6(b)(5) in particular,\40\ in that it is designed
to promote just and equitable principles of trade, to foster
cooperation and coordination with persons engaged in facilitating
transactions in securities, to remove impediments and perfect the
mechanisms of a free and open market, and, in general, to protect
investors and the public interest; and is not designed to permit unfair
discrimination between customers, issuers, brokers, or dealers.
Specifically, the Exchange submits that harmonizing the operation of
the ISO modifier with the ISO modifiers offered by other national
securities exchanges, such as NYSE Arca and Bats BYX, would provide
market participants with consistent and predictable handling of ISOs,
which would facilitate their compliance with Regulation NMS regarding
the use of ISOs, thereby removing impediments and perfecting the
mechanisms of a free and open market.

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

    Moreover, the Exchange believes that requiring the Exchange's
various ISO modifiers to operate in the same manner and clarifying the
handling of ISO crosses simplifies the CHX Rules, which furthers the
objectives of Section 6(b)(1) \41\ in that it further enables the
Exchange to be so organized as to have the capacity to be able to carry
out the purposes of the Act and to comply, and to enforce compliance by
its Participants and persons associated with its Participants, with the
provisions of the Act, the rules and regulations thereunder, and the
rules of the Exchange.

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

B. Self-Regulatory Organization's Statement of Burden on Competition

    The Exchange does not believe that the proposed rule change will
impose any burden on competition that is not necessary or appropriate
in furtherance of the purposes of the Act. To the contrary, the
Exchange believes that the proposed rule change will reduce the
regulatory burden placed on market participants engaged in trading
activities across different markets by harmonizing the operation of the
Exchange's ISO modifier with those of other national securities
exchanges. The Exchange believes that such harmonization across the
various markets will reduce burdens on competition by removing
impediments to participation in the national market system.

C. Self-Regulatory Organization's Statement on Comments Regarding the
Proposed Rule Changes Received From Members, Participants or Others

    No written comments were either solicited or received.

III. Date of Effectiveness of the Proposed Rule Changes and Timing for
Commission Action

    The Exchange believes that the proposal qualifies for immediate
effectiveness upon filing as non-controversial under Section
19(b)(3)(A) of the Act \42\ and paragraph (f)(6) of Rule 19b-4
thereunder.\43\
---------------------------------------------------------------------------

    \42\ 15 U.S.C. 78s(b)(3)(A).
    \43\ 17 CFR 240.19b-4.
---------------------------------------------------------------------------

    The Exchange asserts that the proposed rule change: (1) Will not
significantly affect the protection of investors or the public
interest, (2) will not impose any significant burden on competition,
and (3) and will not become operative for 30 days from the date on
which it was filed, or such shorter time as the Commission may
designate. In addition, the Exchange provided the Commission with
written notice of its intent to file the proposed rule change, along
with a brief description and text of the proposed rule change, at least
five business days prior to the date of filing, or such shorter time as
designated by the Commission.\44\ The Exchange believes that the
proposed rule change raises no novel issues, as the amended ISO
modifier will operate similarly to the ISO modifiers of other national
securities exchanges, such as NYSE Arca and Bats BYX.\45\ As such, the
Exchange has designated this rule filing as non-controversial under
Section 19(b)(3)(A) of the Act \46\ and paragraph (f)(6) of Rule 19b-4
thereunder.\47\

    \47\ 17 CFR 240.19b-4.
---------------------------------------------------------------------------

    At any time within 60 days of the filing of the proposed rule
change, the Commission summarily may temporarily suspend such rule
change if

it appears to the Commission that such action is necessary or
appropriate in the public interest, for the protection of investors, or
otherwise in furtherance of the purposes of the Act. If the Commission
takes such action, the Commission shall institute proceedings under
Section 19(b)(2)(B) of the Act \48\ to determine whether the proposed
rule should be approved or disapproved.

ENVIRONMENTAL PROTECTION AGENCY

[FRL-8926-01-OA]

Request for Nominations of Candidates for Two Review Panels of
the Clean Air Scientific Advisory Committee (CASAC)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

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

SUMMARY: The EPA Science Advisory Board (SAB) Staff Office requests
public nominations of scientific experts for two ad hoc review panels
of the Clean Air Scientific Advisory Committee (CASAC). The review
panels will provide advice through the chartered CASAC on the
scientific and technical aspects of air quality criteria and the
primary and secondary National Ambient Air Quality Standards (NAAQS)
for lead and the secondary NAAQS for oxides of nitrogen, oxides of
sulfur, and particulate matter (PM).

DATES: Nominations should be submitted by September 29, 2021 per the
instructions below.

FOR FURTHER INFORMATION CONTACT: Any member of the public wishing
further information regarding this Notice and Request for Nominations
may contact Mr. Aaron Yeow, Designated Federal Officer (DFO), SAB Staff
Office, by telephone/voice mail at<PHONE_NUMBER> or via email at
<EMAIL_ADDRESS>General information concerning the CASAC can be
found on the following website: https://casac.epa.gov.

SUPPLEMENTARY INFORMATION:
    Background: The CASAC was established pursuant to the Clean Air Act
(CAA) Amendments of 1977, codified at 42 U.S.C. 7409(d)(2), to review
air quality criteria and NAAQS and recommend to the EPA Administrator
any new NAAQS and revisions of existing criteria and NAAQS as may be
appropriate. The CASAC shall also: Advise the EPA Administrator of
areas in which additional knowledge is required to appraise the
adequacy and basis of existing, new, or revised NAAQS; describe the
research efforts necessary to provide the required information; advise
the EPA Administrator on the relative contribution to air pollution
concentrations of natural as well as anthropogenic activity; and advise
the EPA Administrator of any adverse public health, welfare, social,
economic, or energy effects which may result from various strategies
for attainment and maintenance of such NAAQS. As amended, 5 U.S.C.,
App. Section 109(d)(1) of the Clean Air Act (CAA) requires that EPA
carry out a periodic review and revision, as appropriate, of the air
quality criteria and the NAAQS for the six ``criteria'' air pollutants,
including lead, oxides of nitrogen oxides, oxides of sulfur, and PM.
    The CASAC is a Federal advisory committee chartered under the
Federal Advisory Committee Act (FACA). As a Federal Advisory Committee,
the CASAC conducts business in accordance with the Federal Advisory
Committee Act (FACA) (5 U.S.C. App. 2) and related regulations. The
CASAC and the CASAC Review Panels will comply with the provisions of
FACA and all appropriate SAB Staff Office procedural policies.
    History of the Lead NAAQS Review: With the publication of the
National Ambient Standards for lead (81 FR 71906) on October 18, 2016,
the Agency completed its most recent review of the lead NAAQS. The
CASAC's Lead Review Panel for that review was formed in July 2010 and
completed its work in June 2013. In July 2020, the EPA publicly
announced the initiation of the current primary and secondary NAAQS
review for lead (85 FR 40641).
    This Federal Register notice solicitation is seeking nominations
for subject matter experts to serve on the CASAC Lead Review Panel for
the next review of the lead NAAQS that began with a call for
information in July 2020 (85 FR 40641). The Panel will be charged with
reviewing the science and policy assessments, and related documents,
that form the basis for the EPA's review of the lead NAAQS, and will
provide advice through the Chartered CASAC.
    History of the Current Oxides of Nitrogen, Oxides of Sulfur, and PM
Secondary NAAQS Review: In August 2013, the EPA publicly announced the
initiation of the NAAQS review for oxides of nitrogen and oxides of
sulfur (78 FR 53452). In the Integrated Review Plan for the Secondary
NAAQS for Ecological Effects of Oxides of Nitrogen, Oxides of Sulfur,
and Particulate Matter (IRP), EPA recognized the combined contribution
of oxides of nitrogen, oxides of sulfur and PM to deposition of
nitrogen and sulfur and the overlap of effects of these air pollutants
on ecological systems. As such, EPA stated the plan to review the
ecological effects of these three criteria pollutants together in this
review and the IRP was finalized in 2017 following consultation with
the CASAC and the CASAC Secondary NAAQS Review Panel for Oxides of
Nitrogen and Sulfur. The first and second drafts of the Integrated
Science Assessment for Oxides of Nitrogen, Oxides of Sulfur and
Particulate Matter--Ecological Criteria were released in 2017 and 2018
and reviewed by the CASAC and the CASAC Secondary NAAQS Review Panel
for Oxides of Nitrogen and Sulfur. The final ISA was published in 2020
(85 FR 66328). In addition, EPA released the Review of the Secondary
Standards for Ecological Effects of Oxides of Nitrogen, Oxides of
Sulfur, and Particulate Matter: Risk and Exposure Assessment Planning
Document in 2018 (83 FR 42497), which the CASAC Secondary NAAQS Review
Panel for Oxides of Nitrogen and Sulfur provided consultative advice
on.
    On March 31, 2021, the Administrator reset membership of the
Chartered CASAC and existing CASAC panels, including the CASAC
Secondary NAAQS Review Panel for Oxides of Nitrogen and Sulfur. On June
17, 2021, the new Chartered CASAC members were announced.
    This Federal Register notice solicitation is seeking nominations
for subject matter experts to serve on the CASAC Oxides of Nitrogen,
Oxides of Sulfur, and PM Secondary NAAQS Panel to review the Policy
Assessment for the EPA's review of the Oxides of Nitrogen, Oxides of
Sulfur, and PM Secondary NAAQS, and will provide advice through the
Chartered CASAC.
    Request for Nominations: The SAB Staff Office is seeking
nominations of nationally and internationally recognized scientists
with demonstrated expertise and research in the field of air pollution
related to criteria pollutants.
    For the Lead Panel, experts are being sought in the following
fields, especially with respect to lead: Air quality; environmental
fate and transport; exposure and biomarker assessment; biokinetic
modeling; toxicology; epidemiology; risk assessment; biostatistics; and
ecology.
    For the Oxides of Nitrogen, Oxides of Sulfur, and PM Secondary
NAAQS Panel, experts are being sought in the following fields,
especially with respect to nitrogen oxides, sulfur oxides and PM:
Ecological effects of atmospheric concentrations and deposition to
terrestrial, wetland and aquatic ecosystems; ecosystem exposure and
risk assessment/modeling; ecosystem service and resource valuation; and
atmospheric sciences.

    Process and Deadline for Submitting Nominations: Any interested
person or organization may nominate qualified individuals in the areas
of expertise described above. Individuals may self-nominate.
Nominations should be submitted in electronic format (preferred) using
the online nomination form under ``Public Input on Membership'' on the
CASAC web page at https://casac.epa.gov. To be considered, all
nominations should include the information requested below. EPA values
and welcomes diversity. All qualified candidates are encouraged to
apply regardless of sex, race, disability or ethnicity. Nominations
should be submitted by September 29, 2021.
    The following information should be provided on the nomination
form: Contact information for the person making the nomination; contact
information for the nominee; and the disciplinary and specific areas of
expertise of the nominee. Nominees will be contacted by the SABSO and
will be asked to provide a recent curriculum vitae and a narrative
biographical summary that includes: Current position, educational
background; research activities; sources of research funding for the
last two years; and recent service on other national advisory
committees or national professional organizations. Persons having
questions about the nomination process or the public comment process
described below, or who are unable to submit nominations through the
CASAC website, should contact the DFO, as identified above. The names
and biosketches of qualified nominees identified by respondents to this
Federal Register notice, and additional experts identified by the SAB
Staff Office, will be posted in a List of Candidates on the CASAC
website at https://casac.epa.gov. Public comments on each List of
Candidates will be accepted for 21 days from the date the list is
posted. The public will be requested to provide relevant information or
other documentation on nominees that the SAB Staff Office should
consider in evaluating candidates.
    For the EPA SAB Staff Office, a balanced review panel includes
candidates who possess the necessary domains of knowledge, the relevant
scientific perspectives (which, among other factors, can be influenced
by work history and affiliation), and the collective breadth of
experience to adequately address the charge. In forming this expert
panel, the SAB Staff Office will consider public comments on the List
of Candidates, information provided by the candidates themselves, and
background information independently gathered by the SAB Staff Office.
Selection criteria to be used for panel membership include: (a)
Scientific and/or technical expertise, knowledge, and experience
(primary factors); (b) availability and willingness to serve; (c)
absence of financial conflicts of interest; (d) absence of an
appearance of a lack of impartiality; (e) skills working in committees,
subcommittees and advisory panels; and (f) for the panel as a whole,
diversity of expertise and viewpoints.
    Candidates may be asked to submit the ``Confidential Financial
Disclosure Form for Special Government Employees Serving on Federal
Advisory Committees at the U.S. Environmental Protection Agency'' (EPA
Form 3110-48). This confidential form is required for Special
Government Employees (SGEs) and allows EPA to determine whether there
is a statutory conflict between that person's public responsibilities
as an SGE and private interests and activities, or the appearance of a
loss of impartiality, as defined by Federal regulation. The form may be
viewed and downloaded through the ``Ethics Requirements for Advisors''
link on the CASAC home page at https://casac.epa.gov. This form should
not be submitted as part of a nomination.
